Description

Technical Field

[0001] This application relates to a flooring construction method, and more particularly to a large-area emery flooring construction method. Background Technology

[0002] Emery flooring is a common name in China for wear-resistant hardened flooring. It has advantages such as wear resistance, pressure resistance, dust reduction, hard surface, easy cleaning, and economic durability.

[0003] The traditional construction method for large-area emery flooring is as follows:

[0004] 1. The traditional method for constructing large-area emery aggregate flooring involves creating mortar spots, screeds, setting out lines and erecting side formwork, transporting concrete by dump truck, initial leveling by hand, compacting the concrete with a vibrator, and then using a specially designed double-row steel pipe for vibratory compaction and repeated leveling. This method is slow, inefficient, requires extensive side formwork, cannot guarantee construction quality, results in poor levelness and flatness, produces numerous construction joints, is prone to cracking, is labor-intensive, and has low economic benefits.

[0005] 2. Using a laser leveling machine for construction has the advantages of high construction quality, fast construction speed (average 4000㎡ can be completed per day), reduced side formwork support, high degree of automation, low labor intensity and high economic benefits. The flatness of the ground can be ≤±3mm / 2m, but the elevation difference within 1000㎡ is <20mm, which means there is still a problem of large levelness error. Summary of the Invention

[0006] This application provides a method for constructing large-area diamond abrasive flooring to solve the problems existing in related technologies. The technical solution is as follows:

[0007] This application provides a method for constructing a large-area diamond abrasive floor, including the following steps:

[0008] Preliminary calibration of floor elevation: Divide the floor foundation into multiple units, measure the relative elevation of each unit, and calibrate the floor elevation based on the lowest relative elevation among the measured multiple relative elevations to ensure that the floor elevation is not lower than the set elevation, and mark the calibrated floor elevation on the wall.

[0009] Floor zoning: Based on the centerline of the width direction of the floor foundation, the floor foundation is divided into a first area and a second area. The first area is further divided into multiple first sub-areas, which are arranged sequentially along the length direction of the floor foundation. The second area is also divided into multiple second sub-areas, which are arranged sequentially along the length direction of the floor foundation. The width of the first and second sub-areas along the length direction of the floor foundation is 4.5m.

[0010] Subfloor preparation: Roughen the surface of the subfloor base and clean it to remove impurities.

[0011] Preparation of screeds: Screeds are prepared at both ends of the first region along its length, between each two adjacent first sub-regions, at both ends of the second region along its length, and between each two adjacent second sub-regions. The screeds extend along the width of the ground foundation, and the height of the screeds is less than the ground elevation. After the screeds are completed, the levelness and flatness of the screeds are inspected.

[0012] Concrete pouring: Pour concrete into each of the first sub-areas and each of the second sub-areas. During the concrete pouring process, ensure that the concrete stacking height is 20-50mm higher than the ground elevation. Then, manually level the corners of each of the first and second sub-areas.

[0013] Laser screed leveling: The laser emitter of the laser screed is set according to the ground elevation, and the laser receiver of the laser screed is installed at the same time. Then, the laser screed is used to level the concrete on each first sub-area and each second sub-area along the width of the ground. During the leveling process, the concrete is added or reduced manually.

[0014] Sprinkle with corundum;

[0015] Maintenance;

[0016] Cutting a slit.

[0017] In one embodiment, during the floor zoning step, a first concrete transport channel is formed between the first area and the second area. The second area is divided into a third area and a fourth area based on the centerline along its length. A second concrete transport channel is formed between the third area and the fourth area. The second concrete transport channel is perpendicular to the first concrete transport channel and is connected to the first concrete transport channel. Neither the second concrete transport channel nor the first concrete transport channel has screeds. Both the second concrete transport channel and the first concrete transport channel are used for the passage of concrete transport vehicles.

[0018] In one embodiment, during the concrete pouring step, concrete is poured simultaneously into the first area and the second area, followed by concrete pouring into the first concrete transport channel and the second concrete transport channel.

[0019] In one embodiment, prior to the step of applying corundum, the method further includes:

[0020] Grinding and smoothing: After the concrete has initially set, the concrete floor is repeatedly leveled using a scraper, and then a power trowel is used to smooth the leveled concrete floor.

[0021] In one embodiment, the application of corundum is performed in two steps during the spreading step.

[0022] When applying the corundum for the first time, first spread the corundum evenly in a crisscross pattern. Then, use a hand-held power trowel with a special blade to smooth the concrete surface with the corundum. Finally, use a scraper to smooth and calibrate the smoothed concrete surface multiple times.

[0023] When applying the corundum for the second time, first spread the corundum evenly on the ground in a crisscross pattern, then use a ride-on power trowel with a disc to polish the ground with the corundum multiple times, and then use a walk-behind power trowel to finish the wear-resistant surface multiple times.

[0024] In one embodiment, during the maintenance step, the ground is sprayed with water and covered with a film. The film must completely adhere to the ground surface without any air bubbles.

[0025] In one implementation, water spraying and curing are carried out continuously during the cutting process, and after the cutting is completed, water spraying continues and the film curing is restored.

[0026] In one embodiment, after the slit-cutting step, the method further includes:

[0027] Sealing and hardening agent surface layer construction: After the curing is completed, clean the floor surface, then spray the sealing and hardening agent on the floor surface. When the sealing and hardening agent reaches the gel state, clean off the residual sealing and hardening agent, let the floor dry, and then grind and polish the floor.

[0028] In one embodiment, during the application of the sealant hardener surface layer, the sealant hardener is allowed to react on the concrete surface for more than 45 minutes before the residual sealant hardener is cleaned off.

[0029] In one embodiment, during the application of the sealant hardener surface layer, a high-speed polishing machine is used to grind and polish the ground in a cross-shaped manner.

[0030] In one embodiment, after the concrete pouring step, the method further includes:

[0031] Inserting the reinforcing mesh: Prepare the reinforcing mesh in advance, and insert it after the concrete is initially leveled.

[0032] The advantages or beneficial effects of the above technical solutions include at least the following:

[0033] The large-area corundum abrasive construction method of this invention firstly ensures that the thickness of the corundum abrasive floor is not less than the set thickness requirement by initially calibrating the floor elevation. Simultaneously, it facilitates controlling the flatness of the corundum abrasive floor within 3mm / 2m and the overall levelness within 5mm. Then, by rationally dividing the floor foundation into sections and setting screeds at the corners of each section and between sub-sections, when using a laser screed to level the concrete in each sub-section, the screeds on both sides along the length of the floor foundation in each sub-section can serve as the flatness and levelness benchmark, resulting in a corundum abrasive floor with high flatness and levelness. The laser screed achieves higher flatness, thus reducing the flatness and levelness errors of the concrete floor. Simultaneously, screeds can be used as formwork, achieving zero formwork and saving costs. Furthermore, the laser screed provides better overall surface integrity, reducing the likelihood of cracks and improving construction quality and efficiency. Additionally, during laser screeding, manual leveling of the corners and edges of each sub-area solves the problem of laser screeds being unable to level corners, further improving the flatness of the concrete floor and reducing manual grinding, thus further enhancing construction efficiency.

[0039] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0040] See Figure 1 The diagram illustrates a simplified construction method for a large-area corundum flooring project according to a preferred embodiment of the present invention. This method includes the following steps:

[0041] Preliminary calibration of floor elevation: The floor base is a concrete base. The floor base is divided into multiple units. The relative elevation of each unit is measured. The floor elevation is calibrated based on the lowest relative elevation among the multiple measured relative elevations to ensure that the floor elevation is not lower than the set elevation, which is 50mm. The calibrated floor elevation is then marked on the wall.

[0042] Floor zoning: Based on the centerline of the width direction of the floor foundation, the floor foundation is divided into a first area 10 and a second area 20. The first area 10 is further divided into multiple first sub-areas 11, which are arranged sequentially along the length direction of the floor foundation. The second area 20 is divided into multiple second sub-areas 21, which are also arranged sequentially along the length direction of the floor foundation. The width of the first sub-area 11 and the second sub-area 21 along the length direction of the floor foundation is 4.5m, ensuring that the laser screed can pass through without obstruction. The laser screed can level the concrete in the first sub-area 11 and the second sub-area 21 by running once along the width direction of the floor foundation, which helps to further reduce flatness and levelness errors.

[0043] Subfloor preparation: Roughen the surface of the subfloor base and clean it to remove impurities.

[0044] Preparation of screed 30: Screed 30 is prepared at both ends of the first region 10 along its length (i.e., the corner areas at both ends of the first region 10), between each two adjacent first sub-regions 11, at both ends of the second region 20 along its length (i.e., the corner areas at both ends of the second region 20), and between each two adjacent second sub-regions 21. The screed 30 extends along the width of the floor foundation, and the height of the screed 30 is less than the floor elevation. After the screed 30 is completed, the levelness and flatness of the screed 30 are inspected to improve the levelness and flatness of the emery floor.

[0045] Concrete pouring: Pour concrete into each first sub-area 11 and each second sub-area 21. During the concrete pouring process, ensure that the concrete stacking height is 20-50mm higher than the ground elevation. Then, manually level the corners of each first sub-area 11 and each second sub-area 21.

[0046] Laser leveling machine: Set the laser emitter of the laser leveling machine according to the floor elevation on the wall, and install the laser receiver of the laser leveling machine. Then use the laser leveling machine to level the concrete on each first sub-area 11 and each second sub-area 21 along the width of the floor. During the leveling process, add or reduce concrete manually.

[0047] Sprinkle with corundum;

[0048] Maintenance;

[0049] Cutting a slit.

[0050] The large-area corundum abrasive construction method of this invention firstly ensures that the thickness of the corundum abrasive floor is not less than the set thickness requirement by initially calibrating the floor elevation. Simultaneously, it facilitates controlling the flatness of the corundum abrasive floor within 3mm / 2m and the overall levelness within 5mm. Then, by rationally dividing the floor foundation into sections and setting screeds 30 at the corners of each section and between sub-sections, the screeds 30 on both sides along the length of the floor foundation in each sub-section can serve as a flatness and levelness benchmark when leveling the concrete in each sub-section using a laser screed. This ensures that the flatness and levelness of the finished corundum abrasive floor are achieved. The laser screed provides a higher surface smoothness, reducing flatness and levelness errors. Furthermore, the use of screed 30 as a formwork eliminates the need for formwork, saving costs. Additionally, the laser screed improves the overall integrity of the surface, reducing the likelihood of cracks and enhancing construction quality and efficiency. Moreover, the laser screed allows for preliminary leveling of the corners of each first sub-area 11 and each second sub-area 21 manually, addressing the laser screed's inability to level corners. This further improves the smoothness of the laser screed and reduces manual grinding, further increasing construction efficiency.

[0051] In one embodiment, during the initial calibration of the ground elevation, the ground foundation is divided into as many units as possible. For example, each first sub-region 11 is divided into multiple units, and these units are arranged sequentially along the length direction of the first sub-region 11 (i.e., the width direction of the ground foundation). Similarly, each second sub-region 21 is divided into multiple units, and these units are arranged sequentially along the length direction of the second sub-region 21 (i.e., the width direction of the ground foundation). This further improves the calibration accuracy of the ground elevation.

[0052] To facilitate concrete transportation, in one embodiment, during the floor zoning step, a first concrete transport channel 40 is formed by separating a first area 10 and a second area 20. The second area 20 is divided into a third area 22 and a fourth area 23 based on the centerline along its length. A second concrete transport channel 50 is formed by separating the third area 22 and the fourth area 23. The second concrete transport channel 50 is perpendicular to the first concrete transport channel 40 and is connected to the first concrete transport channel 40. Neither the second concrete transport channel 50 nor the first concrete transport channel 40 has screed 30. Both the second concrete transport channel 50 and the first concrete transport channel 40 are used for the passage of concrete transport vehicles.

[0053] In one embodiment, both the second concrete transport channel 50 and the first concrete transport channel 40 are 2m wide, which ensures that electric tricycles transporting concrete can pass through while making it easier to control the flatness and levelness of the emery floor in the areas where the second concrete transport channel 50 and the first concrete transport channel 40 are located, thus helping to further reduce the flatness and levelness errors of the emery floor.

[0054] In one embodiment, during the preparation of the screed 30, the height of the screed 30 is 2-3 mm lower than the ground elevation or the finished ground surface. The concrete strength of the screed 30 is the same as that of the ground concrete. After the screed 30 is constructed, it is cured in a timely manner to improve the quality of the screed 30.

[0055] To further improve construction efficiency, in one embodiment, during the concrete pouring step, concrete is poured simultaneously into the first region 10 and the second region 20, followed by concrete pouring into the first concrete transport channel 40 and the second concrete transport channel 50.

[0056] In one embodiment, during the concrete pouring step, ready-mixed concrete with a strength grade of not less than C25 is used. If necessary, steel fiber reinforced aggregate concrete can be used to reduce cracking. Concrete trucks must supply continuously, with intervals not exceeding 30 minutes. Small tricycles are used for concrete transportation. When delivering concrete, a slump test bucket is first used to test each batch of concrete arriving on site to ensure that its slump is 150±10 mm before it can be used.

[0057] In one embodiment, prior to the step of applying corundum, the method further includes:

[0058] Grinding and slurry preparation: After the concrete has initially set, the concrete surface is repeatedly leveled using a screed, and then a power trowel is used to level the surface to enhance the adhesion of the concrete and allow the abrasive to fully integrate with it.

[0059] Specifically, in one implementation, the application of corundum is carried out in two steps to reduce the shrinkage of the concrete itself.

[0060] When applying the corundum for the first time, first spread the corundum evenly in a crisscross pattern. Then, use a hand-held power trowel with a special blade to smooth the concrete surface with the corundum. Finally, use a scraper to smooth and calibrate the smoothed concrete surface multiple times.

[0061] When applying the corundum for the second time, first spread the corundum evenly on the ground in a crisscross pattern, then use a ride-on power trowel with a disc to polish the ground with the corundum multiple times, and then use a walk-behind power trowel to finish the wear-resistant surface multiple times.

[0062] In one embodiment, during the curing process, the ground is sprayed with water and covered with a film. The film must completely adhere to the ground surface without any air bubbles, in order to prevent uneven water absorption and color differences on the concrete surface, thereby improving the quality of the floor.

[0063] In one implementation, water spraying and curing are carried out continuously during the cutting process, and after the cutting is completed, water spraying continues and the film curing is restored.

[0064] In one embodiment, after the slit-cutting step, the method further includes:

[0065] Sealing and hardening agent surface layer construction: After the 14-day curing period, use a floor scrubber to clean the floor surface, then spray the sealing and hardening agent on the floor surface at a dosage of 0.2-0.3 kg / ㎡. When the sealing and hardening agent reaches a gel state, clean off any remaining sealing and hardening agent. After the floor dries, grind and polish the floor to give it a metallic luster.

[0066] In one embodiment, during the application of the sealant hardener surface layer, the sealant hardener is allowed to react on the concrete surface for more than 45 minutes before the residual sealant hardener is cleaned off.

[0067] In one embodiment, during the application of the sealant hardener surface layer, a high-speed polishing machine is used to grind and polish the ground in a cross-shaped manner to improve the quality of grinding and polishing while increasing construction efficiency.

[0068] In one embodiment, after the concrete pouring step, the method further includes:

[0069] Pressing in steel mesh: Prepare steel mesh in advance. After the concrete is initially leveled, press in the steel mesh. The protective layer of the steel mesh should be 2cm thick to improve the strength of the emery floor.
