Analysis of the application of concrete laser leveling machine in large-area floor construction The concrete laser leveling machine is a device that uses the laser emitted by the transmitter as the reference plane, and controls the leveling head in real time through the laser receiver on the laser leveling machine, thereby achieving high-precision and rapid leveling of concrete. In large-area floor construction, its application is as follows: Application advantages – High-precision leveling: The ground elevation is controlled by a laser system consisting of a laser transmitter, a laser receiver and a leveling rod. The laser transmitter emits lasers at a frequency of 10 times or even higher per second to form a control plane. The laser receiver on the laser leveling machine monitors the leveling head elevation in real time. The computer control system automatically adjusts the leveling head height according to the deviation to ensure the flatness and levelness of large-area floors. The accuracy can reach millimeter level (within ±3mm). Compared with traditional methods, the flatness and levelness are improved by more than 3 times. – High construction efficiency: Mechanized construction replaces a large number of manual labor, and the work efficiency is more than 3-5 times that of manual labor. For example, laser screed construction can adopt large-area compartments, with each compartment area up to 2,000 square meters, reducing the setting of construction joints, while reducing the work of force transmission rods and formwork support, speeding up the construction progress. Some large telescopic arm laser screeds can complete the leveling of 15 square meters of concrete each time, and some equipment can spread up to 5,000 square meters per day. – Improve ground quality: The powerful vibrator can vibrate at a frequency of up to 4,000 times/minute, which can ensure that the concrete is vibrated and compacted, making the entire paved concrete matrix homogeneous and dense, and the density and strength are more than 20% higher than traditional methods, effectively enhancing the wear resistance and impact resistance of the ground. – Save labor costs: The use of concrete laser screeds can save about 35% of labor, and some robot equipment can be remotely controlled by one person, which reduces manpower input while also reducing the labor intensity of workers. – Flexible adaptation to various working conditions: It can automatically control the longitudinal and transverse slopes, and can also be equipped with a three-dimensional special-shaped ground processing system to meet the construction of complex-shaped ground with high requirements such as drainage, such as squares with special drainage designs, airport runways and other places. Application Cases – Industrial Plant: The third phase of the Flanders Plant is an industrial plant for manufacturing transmission parts assembly and testing. The steel fiber concrete metal wear-resistant floor area is 22,000 square meters and the floor thickness is 300 mm. It has high requirements for flatness and bearing capacity. The floor flatness error is required to be controlled within 3 mm. The use of laser leveling machine construction meets high standards. – Underground Garage: The underground garage of the National Treasury Unified Payment Center in Xicheng District, Beijing has an area of ​​10,500 square meters of metal wear-resistant floor and a floor thickness of 200 mm. The use of this equipment has achieved good results; in the construction of the basement concrete floor of a company's production headquarters project in Suzhou, the four-wheel laser floor leveling robot solved the construction problems of large volume, tight schedule, and high strength, and the flatness deviation was controlled within 5 mm. – New Energy Vehicle Intelligent Industrial Park: In order to ensure the safety of AGV transport vehicles, the Feixi New Energy Vehicle Intelligent Industrial Park EPC project has strict requirements on floor quality. The steel fiber concrete leveling process of this project uses a large laser leveling machine, which greatly improves the flatness of the ground. Application Notes – Equipment Debugging and Maintenance: Before construction, the laser transmitter, receiver and other equipment must be accurately installed and debugged to ensure that their position is accurate and they operate normally; during the construction process, the equipment must be regularly inspected and maintained to avoid equipment failures affecting the construction quality and progress. – Construction Site and Environment: The construction site should be cleared of obstacles in advance to ensure that the laser signal is not blocked; at the same time, the impact of environmental factors such as temperature and wind on the construction should be considered, and corresponding measures should be taken to deal with it, such as paying attention to the concrete setting speed at high temperatures and avoiding the shaking of the laser transmitter in windy weather. – Concrete Quality Control: Strictly control the mix ratio, slump, initial setting time and other parameters of the concrete to ensure that the quality of the concrete is uniform and stable, so as to ensure the construction effect of the laser leveling machine. – Personnel operating skills: Operators must undergo professional training, be familiar with the operating procedures and techniques of the equipment, and be able to skillfully deal with various construction situations to ensure smooth construction.

What factors affect the elevation accuracy of the concrete laser leveling machine? The factors that affect the elevation accuracy of the concrete laser leveler are mainly the following: Equipment itself and installation factors – Laser transmitter: If its installation position is unstable, it is subject to collision, vibration, or displacement or angle changes due to environmental factors such as high temperature and strong wind on the site, the emitted laser reference plane will change, resulting in inaccurate elevation. In addition, the accuracy of the laser transmitter itself is limited, and long service life and aging of internal components will also cause deviations in the emitted laser signal. – Laser receiver: If it fails, such as damage to the sensing element, poor contact of the signal transmission line, etc., it cannot accurately receive and analyze the laser signal, and it is difficult to accurately control the elevation of the leveling head; if the installation position is inaccurate or shifts during construction, the received signal will also deviate from the actual elevation. – Leveling head and transmission system: Structural deformation and wear of the leveling head, such as wear and deformation of the scraper, will affect its leveling effect on concrete; transmission system failures, such as belt slippage and chain loosening, will cause the leveling head to run unstably and fail to accurately adjust the height according to the control system instructions, thereby affecting the elevation accuracy. – Hydraulic system: Poor quality of hydraulic oil, impurities, or leakage and unstable pressure in the hydraulic system will reduce the response speed and control accuracy of the hydraulic system, and fail to adjust the leveling head height in a timely and accurate manner. Construction environment factors – Obstacles: Tall buildings, large equipment, and stacked materials at the construction site may block the laser signal, causing the laser receiver to be unable to receive complete and accurate signals, causing the leveling machine to have elevation control deviations in some areas. – Ground foundation conditions: The base surface is uneven and the density is uneven. After the concrete is poured, the concrete surface elevation may be inconsistent due to the settlement difference of the base; soft or raised parts of the base will also affect the normal operation and elevation control of the leveling machine. – Temperature change: Large temperature changes may cause thermal expansion and contraction of equipment components, affecting the mechanical structure of the equipment and the accuracy of the laser system; at the same time, temperature affects the setting speed and fluidity of concrete. If the construction parameters are not adjusted in time, it may also cause deviations in elevation control. – Wind impact: Construction in a windy environment may cause the laser transmitter to shake, affecting the stability of the laser signal; strong winds may also disturb the concrete surface, causing the newly leveled concrete surface to fluctuate, affecting the accuracy of the elevation. Concrete materials and construction factors – Concrete performance: The slump of concrete is inconsistent, which will lead to different fluidity. During the leveling process, the thinner concrete and the drier concrete have different forces on the leveling machine, which will affect the height control of the leveling head and cause elevation deviation; in addition, the unstable setting time of concrete will also affect the construction progress and leveling effect. – Construction operation: Operators are not familiar with equipment operation, such as uneven walking speed, improper lifting and lowering of the leveling head, etc., which will affect the leveling effect and elevation accuracy of the concrete; during the concrete pouring process, uneven distribution, local concrete accumulation or shortage will also cause elevation errors in the leveling machine during the leveling process. – High-level verification: Inaccurate setting of the benchmark leveling point before construction, or damage to the benchmark leveling point during construction, and operating errors of the handheld receiver during the high-level verification, etc., will lead to inaccurate elevation benchmarks introduced into the leveling machine.

What long-term impact does a concrete laser leveling have on construction quality? Long-lasting flatness guarantee An automatic concrete floor levelling machine, such as a concrete laser floor leveling machine, utilizes a laser system for highly precise leveling. It can minimize the error in the flatness of the concrete surface. In the long-term use, this high-precision initial flatness ensures that the pressure is evenly distributed when the ground bears various loads. For example, in an industrial plant, the frequent movement of heavy machinery will not cause concentrated stress due to local unevenness of the ground. This effectively prevents problems such as pitting and sanding on the ground, keeping the ground in good condition for a long time and greatly extending the maintenance cycle of the ground. If you are looking for a concrete laser leveling machine for sale, you can find a device that can achieve such long-term flatness effects Enhance structural stability A concrete laser leveling machine enables more uniform pouring thickness of concrete through accurate leveling. In building structures, uniform concrete thickness helps to ensure the balanced force of the entire structure. Take the floor of a large shopping mall as an example. The floor leveled by a concrete laser leveling machine can better support the upper-level buildings, as well as the loads of people and goods, reducing the risk of structural deformation caused by uneven local thickness. In the long run, this is of great significance for maintaining the overall structural stability of the building, reducing the building structure safety hazards caused by ground problems. The price of a concrete laser leveling machine varies according to different models and functions, but the investment in it can bring long-term structural stability benefits. Improve durability A well-leveled and evenly-thick concrete surface can effectively reduce water penetration. Water is one of the key factors causing concrete corrosion and steel bar rust. For the floor leveled by a concrete laser leveling machine, due to the reduction of water-accumulation areas, it is difficult for water to penetrate into the concrete interior, thus reducing the carbonation rate of concrete and protecting the internal steel bars from rust. This significantly improves the durability of the concrete structure. Over decades of use, it can still maintain good physical properties, reducing the cost and time of large-scale renovation due to insufficient durability. When considering the purchase of a concrete laser leveling machine for sale, durability improvement should be an important factor to consider. Improve wear resistance During the leveling process of a concrete laser leveling machine, the compactness of the concrete surface is improved. Under long-term friction from people walking and vehicle driving, the compact surface can better resist wear. For example, in a logistics warehouse, the frequent operation of forklifts causes serious wear to the ground. The ground constructed by a concrete laser leveling machine has obvious wear-resistance advantages, which can keep the surface intact for a long time, reduce dust generated by ground wear, provide a better guarantee for the warehousing environment, and also reduce the frequency of ground maintenance and replacement. Different concrete laser leveling machine prices are related to their performance in aspects such as wear-resistance improvement.

How to operate the concrete laser leveling machine The operation method of the concrete laser leveling machine generally includes pre-operation preparation, equipment debugging, construction operation and post-operation processing. The following are the specific contents: Pre-operation preparation 1. Site cleaning: Clear the debris and obstacles in the construction site to ensure that the ground is flat and there are no sharp objects to avoid affecting the operation of the equipment or damaging the tires and scrapers and other parts. 2. Equipment inspection: Conduct a comprehensive inspection of the equipment, including whether the connections of each component are firm, whether the electrical system and hydraulic system are normal, whether the laser transmitter and receiver can work normally, whether the water tank and oil tank levels are within the normal range, etc. 3. Material and tool preparation: Prepare the required concrete materials to ensure that their quality and performance meet the construction requirements. At the same time, prepare necessary auxiliary tools such as shovels, trowels, etc. 4. Staffing: Arrange at least one skilled operator and auxiliary construction personnel to be responsible for the loading and paving of concrete. Operators should be familiar with the operation methods and safety precautions of the equipment and wear appropriate personal protective equipment, such as safety helmets and safety shoes. Equipment debugging 1. Laser system debugging: Turn on the laser transmitter and set the height and slope of the laser according to the construction requirements. Install the laser receiver on the corresponding position of the leveler, and adjust the height and angle of the receiver so that it can accurately receive the laser signal. Start the leveler and move the equipment to check the signal reception of the laser receiver to ensure that the signal is stable and accurate. 2. Scraper and vibration plate debugging: According to the paving thickness and construction requirements of the concrete, adjust the height and angle of the scraper to keep a suitable distance from the ground. Generally, the distance between the bottom of the scraper and the ground is slightly less than the design thickness of the concrete. At the same time, debug the vibration frequency and amplitude of the vibration plate. Usually, it is adjusted according to the slump and density requirements of the concrete. The vibration frequency and amplitude can be appropriately increased for concrete with a small slump. 3. Travel system debugging: Start the travel system and check whether the forward, backward, steering and other functions of the equipment are normal. Adjust the travel speed. According to the paving speed of the concrete and the construction progress requirements, select a suitable travel speed, generally within the range of 1-3 meters/minute. Construction operation 1. Concrete loading and paving: Use concrete conveying equipment to transport concrete to the construction site, and auxiliary construction personnel will cooperate to evenly spread the concrete on the ground. The paving thickness should be slightly higher than the designed thickness, generally 5-10 cm higher, to compensate for the concrete sinking during the leveling process. 2. Leveling operation: The operator starts the concrete laser leveling machine and drives the equipment forward slowly. During the movement of the equipment, the scraper will scrape the raised concrete flat, and the vibration plate will vibrate and compact the concrete to make the concrete surface initially flat. During the leveling process, the operator should closely observe the signal changes of the laser receiver, and adjust the height of the scraper and vibration plate in time according to the signal indication to ensure that the flatness of the concrete surface meets the requirements. 3. Edge and corner processing: For corners that are difficult for the equipment to reach, auxiliary construction personnel need to use shovels, trowels and other tools for manual leveling to ensure the flatness and density of the entire construction surface. 4. Multiple leveling: For large-area concrete construction, multiple leveling operations may be required. After the first leveling, wait for the concrete surface to dry slightly, and then perform the second leveling to further improve the flatness and finish of the concrete surface. Post-operation processing 1. Equipment cleaning: After the construction is completed, turn off the power supply of the equipment in time, use a high-pressure water gun or compressed air to thoroughly clean the equipment, and remove concrete residues, dust and other debris on the surface and components of the equipment. In particular, the scraper, vibrating plate, spiral feeder and other parts must be cleaned to prevent damage to the equipment after the concrete solidifies. 2. Component inspection and maintenance: Perform a comprehensive inspection of the equipment to check whether the components are damaged or loose, and repair and tighten them in time if there are any problems. At the same time, lubricate and maintain the parts that need lubrication in accordance with the equipment maintenance requirements, and add or replace lubricating oil, hydraulic oil, etc. 3. Storage equipment: Park the equipment at the designated storage location, ensure that the storage site is flat and dry, and avoid the equipment from being affected by natural factors such as rain and sun. If the equipment is not used for a long time, appropriate protective measures should be taken, such as covering with canvas.

The ground treatment after the construction of the concrete laser leveling machine is an important part of ensuring the quality of the floor. The following are the specific treatment methods Polishing and finishing – Polishing : When the poured and leveled concrete reaches the initial setting, the ground polishing process begins. First, use a single-disc polishing machine and a trowel disc to cross-break the slurry and trowel to ensure the flatness control of the machine operation process. Then, use a 3-meter scraper to rotate 360° to level the surface layer to achieve full control of flatness. After the first disc cross-trowel, professional technicians use a 3-meter scraper to fully level the compacted concrete surface layer. – Finishing : As the disc trowels, the machine uses a blade to smooth it. According to the speed of the strength increase, when the concrete theoretically reaches the final setting, the mechanical vertical knife method is used, combined with the machine speed and blade angle, to perform the final finishing on the surface layer. Maintenance – Moisturizing maintenance: After the floor is finished, use a maintenance blanket or a special maintenance non-woven fabric to cover it and water it to keep it moist. Concrete needs to be cured 12 hours after pouring. It can be covered with plastic cloth, watered, or sprayed for maintenance. The curing should be carried out for at least 7 days. – Temperature control: Ensure that the temperature difference between the inside and outside of the concrete is less than 25℃, assign a special person to watch over it, ensure that the concrete surface is clean and watered in place. Finished product protection – Cover protection: If the upper construction continues on the finished floor, it is necessary to strengthen the protection of the finished product. The paper fiberboard can be used to cover the entire system to protect the concrete surface. – Protective measures: When dismantling the shelf, you can use a protective bamboo fence to cover the entire range of the dismantled shelf, and throw the dismantled steel pipes and fasteners on the bamboo fence to prevent the steel pipes and fasteners from directly hitting the "clear water concrete" floor (ground). Other treatments – Anti-pollution treatment: If there are anti-pollution requirements for the finished floor (ground) surface, a special concrete sealing wax can be applied to the finished surface to form a surface wax coating to prevent pollution from damaging the floor (ground) surface. – Expansion joint cutting: After the concrete is finally set, the expansion joint is cut according to the design requirements to prevent the ground from cracking.

The following is a discussion on the process of using laser leveling machine for floor construction: 1. Construction preparation: – Equipment debugging: Perform a comprehensive inspection and debugging of the laser leveling machine to ensure its good performance and normal operation. – Benchmark setting: Make at least 2 fixed benchmark leveling points based on the original leveling point to control the floor elevation. – Site cleaning: Remove debris, garbage, etc. in the construction area to ensure that the base is flat and clean. – Material preparation: Prepare the required concrete, hardened materials, etc., and ensure that their quality meets the requirements. 2. Concrete paving: – Within the effective range of the telescopic arm of the laser leveling machine, first spread the concrete roughly by hand, and the thickness is slightly higher than the design elevation. – Then the laser leveling machine completes the vibration, compaction, and leveling work at one time to ensure that the concrete surface is flat and uniform. 3. Spreading of hardened materials: – When the concrete is initially set (a 3-5mm mark is left by the finger pressure test), first spread 2/3 of the hardened aggregate (non-metallic aggregate or metal aggregate and alloy aggregate) evenly in the vertical and horizontal directions to allow the material to fully absorb the moisture in the concrete. – Use a smoothing machine to smooth it, and then spread the remaining 1/3 of the hardened aggregate evenly, smooth it several times and then smooth it. The corners should be smoothed and smoothed with a manual trowel. 4. Maintenance and cutting of expansion joints: – After the construction is completed, the curing agent (water plus film, wax, sealing curing agent) can be used for curing, and the curing time should not be less than 7 days. – Cutting should be carried out at the earliest time while ensuring that the cutting does not burst the edge. Generally, the cutting should be completed 1-3 days after completion depending on the weather conditions and the concrete conditions at the time to prevent irregular cracking. The spacing of the cutting joints is determined according to the distance between the workshop columns, and it is preferably no more than 6m. The cutting line should be uniformly marked to ensure that the cutting joints are neat and straight, and the cutting depth should be at least 1/3 of the thickness of the concrete base. 5. Flatness test: – Use f-meter or measuring equipment of the same level to test the flatness to ensure that the flatness of the floor meets the requirements. – Repair the uneven areas detected in time. 6. Seam filling: – Before using the floor, fill the cut seams with seam filling glue to prevent debris from entering the seams and affecting the service life of the floor. The use of laser leveling machine for floor construction can greatly improve the construction efficiency and quality, reduce manual errors, and make the floor flatter and smoother. During the construction process, the operation should be carried out strictly in accordance with the construction process requirements to ensure construction safety and quality.

Exploring the excellent technology of concrete laser leveling machine in floor construction: Taking Shandong Vanse Machinery as an example In the field of modern floor construction, technological innovation continues to promote the development of the industry. As a revolutionary technology, the concrete laser leveling machine is gradually becoming the preferred equipment for floor construction, especially the concrete laser leveling machine series of Shandong Vanse Machinery Technology Co., Ltd., which has attracted worldwide attention with its advanced technology and excellent performance. 1. Working principle and technical advantages of laser leveling machine Laser leveling machine, also known as automatic laser concrete leveling machine, has a core working principle based on high-precision measurement and automatic control of laser technology. Shandong Vanse Machinery's laser leveling machine emits a precise horizontal laser beam through a laser transmitter to establish an absolutely horizontal reference plane for the entire construction area. The laser receiver captures the laser signal in real time. Once the deviation between the leveling machine scraper and the laser plane is detected, the automatic control system will respond quickly and accurately adjust the height of the scraper through the hydraulic system to ensure that the scraper always moves along the laser plane, thereby achieving high-precision leveling of the concrete surface. This advanced working principle gives the laser leveling machine a significant technical advantage. Compared with traditional floor construction methods, laser leveling machines can achieve higher flatness accuracy, and the error can be controlled within a very small range, meeting the construction needs of places such as industrial plants and logistics warehouses that have extremely high requirements for ground flatness. At the same time, its automated construction process greatly reduces the error and time cost of manual operation, significantly improves construction efficiency, and is a truly automatic concrete leveling machine. 2. Construction process and process The use of Shandong Vanse Machinery's concrete laser leveling machine for floor construction has a set of scientific and rigorous process flows. In the construction preparation stage, the construction site must first be fully cleaned and leveled to ensure that the flatness of the base meets the requirements. Then, according to the size and shape of the construction site, the laser transmitter is reasonably installed and calibrated to establish an accurate reference plane for the entire construction process. At the same time, prepare concrete raw materials that meet the design requirements, and strictly control its slump and other indicators. During the concrete pouring process, the concrete is evenly poured into the construction area, and the method of pouring in compartments is adopted. The area of ​​each compartment is reasonably divided according to the actual situation, and generally should not exceed a certain range to ensure the pouring quality of the concrete. After the initial vibration of the concrete, the laser leveling machine (concrete laser leveling floors machine) is started immediately. According to the feedback signal from the laser receiver, the operator accurately controls the walking speed and scraper height of the leveling machine, so that the scraper moves at a uniform speed along the laser plane and accurately level the concrete. During the leveling process, the operator should pay close attention to the flatness of the concrete surface and the working status of the leveling machine, and make adjustments in time. 3.

Technical Principle (I) Laser emission and reception The laser transmitter equipped with Vanse laser leveling machine can be installed on a stable reference point to emit a horizontal laser beam to the construction area to form an accurate plane reference. Whether it is a rotating or fixed laser transmitter, it can be flexibly selected according to the size and shape of the construction site to ensure that the horizontal accuracy can reach ±0.5mm/10m. It uses 635nm or 650nm visible red light wavelengths that are safe for human eyes, which is convenient for construction personnel to observe and calibrate. The power range is 5mW-10mW, which meets the signal strength requirements within the construction range. At the same time, the laser receiver on the leveler can receive laser signals in real time, providing accurate data for subsequent automatic control. (II) Automatic control and feedback When the laser receiver detects that there is a deviation between the position of the leveler scraper and the laser plane, the advanced control system of the Vanse laser leveler begins to play a role. The system adopts PLC (programmable logic controller) or microcomputer control system, with automatic control, manual adjustment and fault diagnosis functions, and uses advanced PID (proportional-integral-differential) control algorithm to automatically adjust the height of the scraper according to the deviation signal. The scraper is driven up or down by the hydraulic system to keep the scraper on the laser plane at all times, thereby ensuring that the flatness error of the concrete surface is controlled within a very small range.
