Description
Technical Field
[0001] This utility model relates to the field of building construction equipment technology, and in particular to a device for controlling the thickness of the concrete protective layer on the water-facing side of a basement exterior wall. Background Technology
[0002] The basement exterior wall concrete protective layer thickness control device is a specialized piece of equipment used in building construction to precisely control the construction thickness of the concrete protective layer on the water-facing side of basement exterior walls. Its core function is to limit the working range and depth of construction tools through structural design, ensuring that the protective layer thickness meets design specifications (e.g., ≥25mm above the groundwater level and ≥30mm below the groundwater level). It also helps improve the quality and efficiency of protective layer construction. This type of device typically needs to be adaptable to basement exterior walls of varying lengths, flexibly adjusting its positioning to avoid obstacles such as wall reinforcement and formwork reinforcement. It can also optimize the work process according to actual construction needs, ultimately achieving a uniform protective layer thickness, a smooth surface, and a strong bond with the wall structure, providing a fundamental guarantee for subsequent waterproofing layer construction and the durability of the wall structure. In traditional construction of concrete protective layers on the water-facing side of basement exterior walls, the thickness is often controlled by static tools such as concrete spacers and rebar positioning supports. This method requires the spacers and supports to be placed point-by-point, which cannot meet the continuous construction needs of walls of varying lengths. For ultra-long walls, positioning blind spots are prone to occur, and excessively large spacing between spacers can lead to localized thickness deviations in the protective layer, making it difficult to achieve overall uniformity control. Furthermore, traditional tools can only passively limit the distance between the rebar and the wall surface, failing to assist in construction operations. Rolling, troweling, and other operations rely entirely on manual experience, easily leading to unevenness on the protective layer surface, and even problems such as air bubbles and build-up, due to uneven pressure and incorrect operating angles. Subsequent repairs and leveling require additional personnel, resulting in low construction efficiency and making it difficult to meet the requirements for efficient and high-quality protective layer construction.
[0003] Therefore, it is necessary to provide a device for controlling the thickness of the concrete protective layer on the water-facing side of the basement exterior wall to solve the above-mentioned technical problems. Utility Model Content

Multiple adjacent control boards are inserted and fixed in the vertical direction.

[0012] Compared with related technologies, the present invention provides a device for controlling the thickness of the concrete protective layer on the water-facing side of a basement exterior wall, which has the following advantages: This utility model provides a device for controlling the thickness of the concrete protective layer on the water-facing side of a basement exterior wall. The primary advantage of this device is its versatility and adaptability. Multiple convex plates are spliced together to achieve controllable base length. Combined with a splicable control plate, the span of the device can be flexibly adjusted according to different lengths of the basement exterior wall, eliminating the need for custom-made devices for different wall sizes, reducing equipment costs and avoiding control blind spots. Secondly, it provides precise thickness control. The movable seat moves parallel to the water-facing side to avoid obstacles such as rebar positioning parts and formwork reinforcements. The positioning plate moves vertically along the water-facing side to precisely adjust the height of the control plate according to the designed thickness. During construction, the roller brush is placed on the control plate, directly limiting the brush's application range and avoiding inconsistent protective layer thickness caused by uneven force or experience deviations during manual operation, ensuring that the protective layer thickness of each wall section meets the specifications. Finally, it offers high operational convenience. No complex measurement and calibration steps are required. Construction personnel only need to adjust the device's position and height according to the design parameters to perform standardized operations using the control plate, reducing reliance on the professional skills of construction personnel and improving construction efficiency.
[0013] This invention provides a device for controlling the thickness of the concrete protective layer on the water-facing side of a basement exterior wall. The device features a scraper on one side of the control panel, which, during application with a roller brush, scrapes the already applied protective layer. The core advantage is optimized protective layer forming quality. After roller brush application, uneven coating, air bubbles, or excess material buildup are inevitable. The scraper, working in tandem with the roller brush, can smooth out protruding excess material in real time, squeezing out air bubbles within the coating, resulting in a smoother and denser protective layer surface. This reduces the risk of poor adhesion and water leakage in the waterproofing layer later due to uneven surface. Simultaneously, it strengthens… To ensure the uniformity of the protective layer, avoid localized areas of excessive material thickness leading to drying shrinkage and cracking, or localized areas of insufficient impermeability due to insufficient material thickness. This ensures consistent overall performance of the protective layer, further guaranteeing subsequent waterproofing effects and structural durability. A cleaning brush is installed on the other side of the control panel to clean the water-facing surface before construction. This effectively removes floating dust, cement slurry, fine sand, and other impurities from the wall surface, preventing impurities from getting trapped between the protective layer and the wall itself. This prevents the protective layer from becoming weakly bonded, resulting in hollow areas or detachment later due to impurities. This ensures the protective layer and wall form a unified whole, improving impermeability and protection. Attached Figure Description

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0016] Furthermore, the terms used below are defined based on the functions of this utility model and may vary depending on the user's or operator's intent or convention. Therefore, these terms are defined based on the entire contents of this specification.
[0017] Please see Figures 1-7 The present invention discloses a device for controlling the thickness of concrete protective layer on the water-facing side of basement exterior wall, comprising a base 1, a movable seat 2, a positioning plate 3, and a control plate 4. The base 1 is formed by merging multiple convex plates 11 along a straight line, and any two adjacent convex plates 11 are locked and fixed by positioning bolts 12. According to the actual construction site, the corresponding number of convex plates 11 are selected according to the length of the underground exterior wall so that the overall length of the base 1 matches the exterior wall. Meanwhile, in actual construction, a small number of the convex plates 11 can be fixed to the construction ground. The fixing method can be the traditional rivet fixing. A convex groove 13 is provided on the top of any convex plate 11. The movable seat 2 is inserted into the convex groove 13. The movable seat 2 can move within the convex groove 13, and the moving direction is parallel to the water-facing surface of the outer wall. A slot 21 is provided at the center of the top of the movable seat 2. A displacement block 23 is inserted into the slot 21. The displacement block 23 can move along the slot 21 in a direction perpendicular to the water-facing surface of the outer wall. A threaded hole 22 is provided on one side of the slot 21. A threaded locking rod 24 is installed in the threaded hole 22 by thread. When moving the displacement block 23, the threaded locking rod 24 should be loosened so that its end face is separated from the side wall of the displacement block 23. When locking, simply rotate the threaded locking rod 24 so that its end face is tightly attached to the side wall of the displacement block 23. To further increase the locking strength of the threaded locking rod 24 on the displacement block 23, an internal groove is provided on the end face of the threaded locking rod 24, and a rubber gasket is embedded in the internal groove. A grid pattern is provided at the end of the rubber gasket, and the rubber gasket with the grid pattern is in direct contact with the side wall of the displacement block 23. The positioning plate 3 is horizontally fixed on the top of the displacement block 23, and a connecting plate 31 is fixedly installed on the top of the positioning plate 3. The movement mode of the connecting plate 31, the positioning plate 3, and the displacement block 23 is consistent. The control plate 4 is symmetrically fixed on the upper end face of the connecting plate 31, that is, the control plate 4 moves synchronously with the connecting plate 31; The control panel 4 has an L-shaped cross-section, and its back is flush with the side wall of the positioning plate 3. The installation position of the control panel 4 relative to the connecting plate 31 can be referenced. Figure 1 As shown, the control plate 4 has two rows on the top of the connecting plate 31, and there is a construction gap between the two rows of control plates 4. The construction gap is used to place the roller brush tool for the protective layer. Multiple adjacent control plates 4 are inserted and fixed in the vertical direction. According to the actual height of the exterior wall, the corresponding number of control plates 4 are spliced and installed. In actual construction, simply place the roller brush tool at the construction gap position and roll it up and down along the control plate 4 to effectively control the construction thickness of the protective layer. In this embodiment, the span of the device can be flexibly adjusted according to the different lengths of the basement exterior wall, eliminating the need for separate customization for walls of different sizes, reducing equipment costs and avoiding control blind spots; The movable seat 2 can move parallel to the water-facing surface to avoid obstacles such as steel reinforcement positioning parts and formwork reinforcement parts. The positioning plate 3 can move vertically along the water-facing surface to precisely adjust the height of the control plate according to the design thickness (such as 25mm, 30mm). During construction, the roller brush tool is placed on the control board 4 for operation, which can directly limit the construction range of the roller brush and avoid the uneven thickness of the protective layer caused by uneven force and experience deviation during manual operation, ensuring that the thickness of the protective layer of each section of the wall meets the specifications. Furthermore, construction workers only need to adjust the position and height of the device according to the design parameters to carry out standardized operations with the help of the control panel 4, reducing the reliance on the professional skills of construction workers and improving construction efficiency.
[0018] In another embodiment, see Figures 1-7The outer wall of the control panel 4 has a limiting groove 41, and a limiting block 42 is inserted into the limiting groove 41. A support frame 43 is fixedly installed on the outer side of the limiting block 42, and an auxiliary block 44 is installed on the inner side of the support frame 43. The auxiliary block 44, the support frame 43 and the limiting block 42 can be understood as a whole. The three can move along the splicing path of the control panel 4, that is, parallel to the water-facing surface of the outer wall. An inner groove 441 is provided at the center of the outer side wall of the auxiliary block 44. In this embodiment, the roller brush tool can be placed in the inner groove 441 for construction. One of the support frames 43 is connected to a rotating shaft 46 in a damped rotatable manner at the center of its outer side. A scraper 47 is fixedly installed on the rotating shaft 46. When the roller brush tool is working in the inner groove 441, it drives the auxiliary block 44 and the support frame 43 to move, and drives the scraper 47 to scrape the protective layer that has been roller brushed. The scraper 47 can scrape the excess material in real time while the roller brush is working, and squeeze out the air bubbles inside the coating, making the surface of the protective layer smoother and denser, reducing the risk of poor adhesion and water leakage of the waterproof layer due to uneven surface in the later stage. At the same time, it can enhance the uniformity of the protective layer, avoid drying shrinkage and cracking caused by excessive local material thickness, or insufficient impermeability caused by excessive local thinness, ensure the overall performance of the protective layer is consistent, and further guarantee the subsequent waterproofing effect and structural durability.
[0019] Both the support frame 43 and the scraper 47 are made of ferromagnetic material. The outer wall of the support frame 43 is magnetically fitted with a limiting magnetic rod 431. In this way, when adjusting the angle of the scraper 47, the magnetic attraction of the limiting magnetic rod 431 can be used to further lock the position of the scraper 47, preventing the scraper 47 from deflecting during operation.
[0020] In another embodiment, reference is made to Figures 1-7 One of the support frames 43 has an adjustment groove 432 on its outer side wall. An adjustment seat 51 is inserted into the adjustment groove 432. A fixing bolt is installed inside the adjustment seat 51 by thread. A positioning shaft 52 is rotatably installed in the center of the adjustment seat 51. One end of the positioning shaft 52 extends into the limiting groove 41. A cleaning brush 53 is provided on the outer ring of the positioning shaft 52. The cleaning brush 53 can work simultaneously with the roller brush tool. That is, the cleaning brush 53 cleans the water-facing surface under the action of the auxiliary block 44 and other structures. It can effectively remove floating dust, cement slurry, fine sand and other impurities from the wall surface, avoid impurities from being trapped between the protective layer and the wall body, and prevent the protective layer from not adhering firmly, becoming hollow or falling off due to impurities in the later stage. It ensures that the protective layer and the wall form an integral whole and improves the anti-seepage and protective effect. Loosening the fixing bolts allows for adjustment of the position of the adjusting seat 5 relative to the support frame 43, thereby changing the contact area of the cleaning brush 53 with the wall surface and expanding its applicability.
[0021] Furthermore, a drive gear 54 is installed at one end of the positioning shaft 52 extending into the limiting groove 41. A toothed block 55 is arranged along the path on the inner wall of the limiting groove 41, and the drive gear 54 and the toothed block 55 mesh with each other. During the rising or falling process, the positioning shaft 52 will drive the drive gear 54 at the end position to gradually contact the toothed block 55. The positioning shaft 52 and the cleaning brush 53 rotate together. This rotation cleaning can deal with new impurities generated during the construction process in real time, and prevent impurities from adhering to the surface of the undried protective layer or the wall in time, so as to maximize the cleanliness of the construction surface and provide a pre-guarantee for the high-quality formation of the protective layer.
[0022] A connecting rod 45 is provided between the control plates 4, and the two ends of the connecting rod 45 are fixedly connected to the side wall of the auxiliary block 44, so that the positions of the two auxiliary blocks 44 are locked. The two are the same relative to the control plate 4, and it is easy to operate when the roller brush tool is placed on the auxiliary block 44.
[0023] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
