Description

Technical Field

[0001] This invention relates to the field of building engineering leveling technology, and more specifically, to a leveling device and method for primary structure floor concrete. Background Technology

[0002] With the rapid development of my country's national economy, integrated structural decoration construction has gradually entered a popular era, especially in first-tier cities where the integrated structural decoration construction market for fully furnished apartments has developed rapidly, with its market share steadily increasing year by year. Traditionally, unfinished apartments require a 5cm thick C20 fine stone concrete leveling layer for the interior floors, serving as the base layer for the owner's subsequent floor tiling or wood flooring installation. If this leveling layer (base layer) is not properly treated, it can cause quality problems such as hollow areas, sandiness, shrinkage, and cracks, and also reduce the floor height, increase construction time, and raise maintenance costs.

[0003] In existing technologies, floor leveling is usually done by using a screed or a roller. Screed leveling has low precision, while roller leveling can cause concrete to stick to the roller, resulting in an uneven surface of the leveling layer. Summary of the Invention

[0004] The present invention aims to provide a leveling device and method for concrete floor slabs in a single-stage structure, in order to solve the problems of low flatness accuracy when using a scraper for leveling and unevenness of the leveling layer surface when using a roller for leveling.

[0005] This invention is achieved using the following technical solution:

[0006] The present invention provides a primary structure concrete leveling device, including a leveling frame, wherein the leveling frame is connected to multiple support columns, the support height of each support column is adjustable, and a tubular level is installed on the leveling frame.

[0007] The leveling frame is provided with pedestrian walkways on both sides, and the leveling frame is provided with guide rails. Push rods are provided on the guide rails and can move back and forth along the guide rails.

[0008] A leveling tool is connected to the push rod, and the lower end of the leveling tool is at the same elevation as the designed elevation of the top surface of the floor leveling layer.

[0009] As a preferred technical solution:

[0010] The leveling frame includes a set of oppositely arranged transverse wall panels and a set of oppositely arranged longitudinal wall panels, which together form a hollow column.

[0011] As a preferred technical solution:

[0012] A tubular level is installed on the top surface of both the transverse wall panel and the longitudinal wall panel.

[0013] As a preferred technical solution:

[0014] The bottom surface of the scraper is arc-shaped, with the lowest point in the middle and the highest points at the front and rear ends.

[0015] As a preferred technical solution:

[0016] A guide rail is installed on the top of each of the two transverse wall panels, the guide rails are arranged along the length of the transverse wall panels, and the push rod is arranged between the two guide rails.

[0017] As a preferred technical solution:

[0018] The push rod has sliders installed at both ends, and the sliders are adapted to the corresponding guide rails. The sliders have slots formed on them, and the sliders are engaged with the guide rails. The sliders can slide back and forth along the guide rails.

[0019] As a preferred technical solution:

[0020] The support column is a screw rod, and the leveling frame has multiple screw holes. The screw rod is connected to the leveling frame by a thread.

[0021] As a preferred technical solution:

[0025] The present invention further provides a leveling method based on the above-mentioned primary structural floor concrete leveling device, comprising the following steps:

[0026] Step 1: From the project elevation control point, transfer the floor structure design elevation +50cm line to the floor elevation control stake. The floor structure design elevation +50cm line provides a reference for the pouring of the floor concrete foundation.

[0027] Step 2: Adjust the support height of each support column so that the lower end elevation of the leveler is consistent with the design elevation of the top surface of the floor leveling layer, and ensure that all the pipe levels on the leveling frame are horizontal.

[0028] Step 3: Pour concrete on the concrete subfloor to form a floor leveling layer. Before the concrete sets, level it using the primary structural floor concrete leveling device. Use the scraper to scrape the concrete surface back and forth until the elevation and flatness of the floor leveling layer meet the standard for a floor that does not require leveling.

[0029] Step 4: Based on the floor structure design elevation +50cm line, check again whether the elevation and flatness of the top surface of the leveling layer of each floor meet the requirements.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1

[0039] like Figures 1-3 As shown in the figure, this embodiment proposes a single-stage concrete leveling device for floors, including a leveling frame connected to multiple support columns for supporting the leveling frame. One end of each support column is connected to the leveling frame, and the other end rests on the floor surface. The support height of each support column is adjustable, facilitating the leveling frame to be leveled. The floor surface includes a concrete sub-base 12 and a leveling layer on its upper surface. In this embodiment, the support columns rest on the concrete sub-base 12.

[0040] In this embodiment, the support column is a screw 3, and the leveling frame has multiple screw holes. The screw 3 is connected to the leveling frame by a thread. The support height of the support column can be adjusted by adjusting the length of the screw 3 screwed into the screw hole.

[0041] In this embodiment, the leveling frame includes a set of opposing transverse wall panels 1 and a set of opposing longitudinal wall panels 2, which together form a hollow column. Of course, the structure of the leveling frame is not limited to this; other frame structures are also possible.

[0042] In this embodiment, a screw rod 3 is installed at the connecting corner of the transverse wall panel 1 and the longitudinal wall panel 2 to achieve uniform support.

[0043] The top surfaces of the transverse wall panel 1 and the longitudinal wall panel 2 are each equipped with a tube level 4. By adjusting the length of each of the screws 3, the bubble of all the tube level 4 is centered, thereby achieving the leveling of the leveling frame.

[0044] A pedestrian walkway 5 is provided on the leveling frame. In this embodiment, a cantilever slab is connected to the outer side of the top of the two horizontal wall panels 1 to serve as a pedestrian walkway 5. A protective fence 6 is installed on the outer side of the pedestrian walkway 5, and a protective door 7 is installed at each end of the pedestrian walkway 5.

[0045] Depending on the floor area, multiple leveling frames can be installed on the concrete subfloor 12 of the floor, and the multiple leveling frames are spliced ​​together sequentially on the concrete subfloor 12 of the floor.

[0046] A guide rail 8 is mounted on the top of each of the two transverse wall panels 1, and the guide rail 8 is arranged along the length of the transverse wall panel 1. A push rod 9 is arranged between the two guide rails 8, and a slider 10 is mounted on each end of the push rod 9. The slider 10 is adapted to the corresponding guide rail 8. A slot is formed on the slider 10, and the slider 10 is engaged with the guide rail 8. The slider 10 can slide back and forth along the guide rail 8, thereby driving the push rod 9 to move back and forth along the guide rail 8.

[0047] A leveling tool 11 is mounted on the push rod 9. The bottom surface of the leveling tool 11 is for contact with the concrete. The leveling tool 11 follows the push rod 9 and is pushed forward along the guide rail 8 to level the concrete. The bottom surface of the leveling tool 11 is curved, with the lowest point in the middle and the highest points at the front and rear ends. The lowest point of the curved surface contacts the concrete. Because the front and rear ends of the bottom surface of the leveling tool 11 are higher than its middle point, it is possible to avoid the leveling tool 11 pushing up and accumulating concrete in front of it during the scraping process. The curved surface design allows for smooth leveling of the concrete, achieving the leveling of the floor surface leveling layer.

[0048] Before the concrete of the floor leveling layer has fully set, the concrete surface is leveled back and forth using the scraper 11 until the elevation and flatness of the floor leveling layer meet the standards for a floor that does not require leveling. During the operation, workers stand on the pedestrian walkway 5 outside the transverse wall panel 1 and simultaneously push both ends of the push rod 9.

[0049] To facilitate forward pushing by workers, the push rod 9 is a roller, and the slider 10 is a rolling slider. The slider 10 engages with the guide rail 8 and is tumbled to the guide rail 8. The slider 10 and the roller roll together forward or backward. To prevent the leveler 11 from rolling along with the roller, the leveler 11 is connected to the roller via a bearing, and the leveler 11 always remains in contact with the concrete surface.

[0050] The leveling method based on the above-mentioned primary structural floor concrete leveling device includes the following steps:

[0051] Step 1: From the project elevation control point, use a level or steel ruler to transfer the floor structure design elevation +50cm line to the floor elevation control stake. The floor structure design elevation +50cm line provides a reference for the pouring of the floor concrete foundation 12.

[0052] Step 2: Adjust the support height of each support column so that the lower end elevation of the scraper 11 is consistent with the design elevation of the top surface of the floor leveling layer, and make all the pipe levelers 4 on the leveling frame level.

[0053] Step 3: Pour concrete on the concrete subbase 12 of the floor to form a floor leveling layer. Before the concrete sets, level it using the above-mentioned primary structure floor concrete leveling device, so that the scraper 11 scrapes the concrete surface back and forth until the elevation and flatness of the floor leveling layer reach the standard of a floor that does not require leveling.

[0054] Step 4: Based on the floor structure design elevation +50cm line, check again whether the elevation and flatness of the top surface of the leveling layer of each floor meet the requirements.

[0055] The concrete leveling device for primary structural floors described in this invention enables rapid, efficient, and precise leveling of primary structural floors. Based on the size and shape of the primary structural floor area, a certain number of elevation control lines are marked at different locations around the perimeter. Using these control lines as a reference, the leveling frame is adjusted by cooperating with the telescopically adjustable support columns and the tubular level 4 on the leveling frame. Finally, the leveling is achieved by manually moving the scraper 11. This device is highly adaptable, fast-paced, and highly accurate, significantly improving construction efficiency and reducing construction costs.

[0056] Example 2

[0057] The difference between this embodiment and Embodiment 1 is that the two ends of the push rod 9 are connected to a driving device, which provides power to the push rod 9, so that the push rod 9 automatically rolls and stops on the guide rail 8, realizing automated leveling, which helps to reduce the workload of workers and improve work efficiency.

[0058] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
