Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an auxiliary device for leveling walls in building construction. Background Technology

[0002] Wall leveling is a crucial step in building construction to achieve a smooth wall surface. It typically involves scraping, smoothing, and other operations to ensure a tight fit and a flat appearance during subsequent finishing processes (such as tiling and painting). The quality of this step directly affects the building's decorative effect and structural stability, making it an indispensable part of construction.

[0003] In actual construction, traditional wall leveling methods have the following shortcomings:

[0004] First, the lack of a stable positioning device makes it easy for the leveling benchmark to shift due to device shaking during construction, especially when working on large-area walls, making it difficult to ensure overall flatness.

[0005] Secondly, the screed tool has a fixed length, requiring frequent tool changes when facing walls of different widths. This is cumbersome and inefficient. Furthermore, mortar tends to stick to the tool during the screeding process, affecting the leveling accuracy and increasing the workload of subsequent cleaning. Utility Model Content

[0006] In view of the shortcomings of the existing technology, this utility model provides an auxiliary device for leveling the wall surface in building construction, which overcomes the shortcomings of the existing technology and effectively solves the problems of lack of stable positioning device, cumbersome operation and low efficiency.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A wall leveling auxiliary device for building construction includes a wall backing plate. Positioning plates are fixedly connected to both ends of the top outer wall of the wall backing plate. An array of pulleys is rotatably connected to the inner wall of one side of the wall backing plate. A baffle is slidably connected to the outer wall of one end of the wall backing plate, and a screw rod is screwed onto the inner wall of the baffle. One end of the screw rod is rotatably connected to the outer wall of one side of the wall backing plate. A scraper is welded to the outer wall of one side of the baffle, and an extension blade is slidably connected to the inner wall of the scraper. Adjacent fastening knobs are installed between the scraper and the extension blade.

[0009] Preferably, the outer wall of the top of the extension blade is provided with a strip groove, and the fastening knob is disposed through the inner wall of the strip groove.

[0010] Preferably, the outer wall of one side of the scraper is provided with an array of first serrations, and the outer wall of one side of the extended blade is provided with an array of second serrations.

[0011] Preferably, a handrail is welded to the outer wall of the wall panel on the side of the pulley.

[0012] Preferably, a tile is provided on one side of the wall panel, and a wall surface is provided on the other side of the tile.

[0013] Preferably, the pulley is slidably connected to the outer wall of the tile, and the positioning plate is tightly attached to the outer wall of the tile.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The wall leveling auxiliary device for building construction designed in this paper solves the problem of unstable positioning by cooperating with the wall support plate, positioning plate and pulley. The positioning plate is close to the outer wall of the tile to form a stable benchmark. The pulley reduces friction when sliding on the tile, ensuring that the device moves smoothly and avoiding insufficient flatness of the wall due to positioning deviation in traditional construction, thus improving the leveling accuracy.

[0016] 2. The wall leveling auxiliary device designed in this building construction solves the tool compatibility problem by combining a scraper and an extension blade. Loosening the fastening knob allows the extension length of the extension blade to be adjusted along the strip groove to adapt to walls of different widths, eliminating the need for frequent tool changes. At the same time, the first and second saw teeth reduce mortar adhesion, reduce cleaning difficulty, and effectively improve construction efficiency. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 Example 1: A wall leveling auxiliary device for building construction includes a wall backing plate 1. Both ends of the top outer wall of the wall backing plate 1 are fixedly connected to positioning plates 2, and an array of pulleys 3 are rotatably connected to the inner wall of one side of the wall backing plate 1. A baffle 4 is slidably connected to the outer wall of one end of the wall backing plate 1, and a screw rod 5 is screwed onto the inner wall of the baffle 4. One end of the screw rod 5 is rotatably connected to the outer wall of one side of the wall backing plate 1.

[0024] The positioning plates 2 at both ends of the top of the wall back plate 1 are used to fit the sides of the tile 13 to form a longitudinal positioning reference, ensuring that the device remains perpendicular to the wall 14. The pulley 3 on one side of the wall back plate 1 can roll along the surface of the tile 13, which not only supports the weight of the device but also reduces the resistance to movement, allowing the device to move up and down smoothly and providing a stable carrier for leveling operations. The baffle 4 is slidably connected to one end of the wall back plate 1. When the screw 5 is rotated, the baffle 4 slides along the wall back plate 1 to adapt to the needs of leveling layers of different thicknesses.

[0025] In this embodiment, the problem of unstable positioning is solved by the cooperation of the wall back plate 1, the positioning plate 2 and the pulley 3. The positioning plate 2 is in close contact with the outer wall of the tile 13 to form a stable reference. The pulley 3 reduces friction when sliding on the tile 13, ensuring that the device moves smoothly and avoiding insufficient flatness of the wall surface 14 caused by positioning deviation in traditional construction, thus improving the leveling accuracy.

[0026] In embodiment 2, a scraper 6 is welded to one side of the outer wall of the baffle 4, and an extension blade 7 is slidably connected to the inner wall of the scraper 6. Adjacent fastening knobs 8 are installed through the scraper 6 and the extension blade 7. A strip groove 9 is opened on the top outer wall of the extension blade 7, and the fastening knob 8 is disposed through the inner wall of the strip groove 9. An array of first serrations 10 is provided on one side of the outer wall of the scraper 6, and an array of second serrations 11 is provided on one side of the outer wall of the extension blade 7.

[0027] The extended blade 7 slides within the scraper 6, and the strip groove 9 provides a track for its movement. The fastening knob 8 passes through the strip groove 9 and can fix the position of the extended blade 7 when tightened, so as to achieve flexible adjustment of the leveling range. The first saw tooth 10 of the scraper 6 and the second saw tooth 11 of the extended blade 7 can cut off excess mortar, reduce the adhesion area between the tool and the mortar, and ensure the smoothness of the leveled surface.

[0028] In this embodiment, the tool compatibility problem is solved by combining the scraper 6 and the extension blade 7. Loosening the fastening knob 8 allows the extension length of the extension blade 7 to be adjusted along the strip groove 9, adapting to different widths of wall surfaces 14 without the need for frequent tool changes. At the same time, the first saw tooth 10 and the second saw tooth 11 reduce mortar adhesion, reduce cleaning difficulty, and effectively improve construction efficiency.

[0029] A handrail 12 is welded to the outer wall of the wall panel 1 on one side of the pulley 3.

[0030] The handrail 12 is welded to the side of the wall panel 1 near the pulley 3, making it easy for construction workers to hold and control the direction and force of the device's movement, thus improving the convenience and stability of operation.

[0031] A tile 13 is provided on one side of the wall panel 1, and a wall surface 14 is provided on one side of the tile 13. The pulley 3 is slidably connected to the outer wall of the tile 13, and the positioning plate 2 is tightly attached to the outer wall of the tile 13.

[0032] Tile 13 serves as a positioning reference, pulley 3 slides and engages with its outer wall, and positioning plate 2 is in close contact with its edge, ensuring that the device is always leveled with tile 13 as the reference, and ensuring that the wall surface 14 and tile 13 have the same installation flatness.

[0033] Working principle: During construction, first place the pulley 3 on one side of the wall back plate 1 on the surface of the tile 13, so that the positioning plate 2 is close to the outer wall of the tile 13. Adjust the position of the device through the handle 12 to ensure that the wall back plate 1 is parallel to the wall surface 14. According to the leveling width requirement, loosen the fastening knob 8, slide the extension blade 7 along the strip groove 9 to the appropriate length, and then tighten the fastening knob 8 to fix it. Turn the screw 5 to drive the baffle 4 and scraper 6 to move, so that the scraper 6 and the extension blade 7 are close to the area of ​​the wall surface 14 to be leveled.

[0034] The construction worker holds the handle 12 and pushes the device to slide along the surface of the tile 13. The pulley 3 rolls to reduce resistance. The first saw tooth 10 of the scraper 6 and the second saw tooth 11 of the extended blade 7 scrape the mortar. Excess mortar falls off along the saw teeth to avoid sticking. By repeatedly sliding, using the positioning plate 2 and the reference effect of the tile 13, the leveling layer of the wall surface 14 is ensured to be flat and consistent, and the efficient and precise leveling operation of the wall surface 14 is completed.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
