Description

Technical Field

[0001] This utility model relates to the field of bridge three-wall waterproofing construction technology, specifically, to a construction tool for waterproofing the inner walls of a bridge. Background Technology

[0002] As an important protective component of the bridge structure, the inner side of the bridge's three walls is constantly exposed to a humid and dusty environment. To address the common problem of leakage in areas with stress concentration and complex structures in the bridge's three walls, the bridge engineering community has abandoned traditional rigid or overlapping waterproofing methods and instead adopted polyurethane waterproof coatings with high elasticity, seamless integrity, and excellent durability. Through systematic base treatment and standardized construction, a reliable flexible waterproof layer is formed, thereby fundamentally ensuring the safety and durability of the bridge's main structure.

[0003] Existing coating methods mainly rely on manual hand-held brushes or ordinary rollers. However, these methods are prone to uneven coating, missed areas, or accumulation during the coating process, which affects the waterproofing effect. Utility Model Content

[0004] The present invention aims to solve the problem that when workers are moving between multiple construction sites, they need to frequently and manually disassemble and assemble formwork for construction, which is cumbersome, difficult, and affects construction efficiency.

[0005] To solve the above problems, this utility model provides a waterproof coating construction tool for the three walls of a bridge, which is suitable for the construction of the three walls of a bridge. The three walls of the bridge include an A wall, a B wall and a protective wall, and include a block-shaped skeleton, with a plate-shaped coating component connected to the bottom of the skeleton. The width of the frame is not greater than the inner wall thickness of the three walls, so that the coating material fits into the inner wall of the three walls of the bridge.

[0006] The present invention provides a waterproof coating application tool for the three inner walls of a bridge, which, compared with the prior art, has the following beneficial effects, but is not limited to: This waterproofing coating application tool for the three walls of the bridge is used by operators who first manually apply a single coat of the evenly mixed coating to the areas to be coated on the inner walls. Then, the frame is attached to the steps of the three walls, ensuring the coating material adheres to the inner walls. The operator moves the frame at a uniform speed along the direction of the three walls, spreading the coating evenly across the area to be coated, forming a waterproof layer. The operator moves the tool while pre-applying the coating, ensuring continuous application. The coating material acts as a temporary support and guide layer for the coating, maintaining bidirectional contact with both the coating and the wall surface. This prevents the coating from piling up due to its fluidity when applied directly to the wall, and the adherence of the coating material to the inner walls ensures uniform coating thickness during transfer, preventing missed areas and effectively improving the waterproofing effect of the three walls.

[0007] Furthermore, the frame is made of square steel.

[0008] Furthermore, the square steel surface is coated with a hot-dip galvanized layer.

[0009] Furthermore, the coating component is a steel plate.

[0010] Furthermore, the steel plate is welded to the square steel.

[0011] Furthermore, the surface of the steel plate is ground to form a rough surface.

[0012] Furthermore, a handle is fixedly mounted on the frame.

[0013] Furthermore, the width of the skeleton is adapted to the inner wall thickness of the A wall.

[0014] Furthermore, the width of the skeleton is adapted to the inner wall thickness of the B wall.

[0015] Furthermore, the width of the frame is adapted to the thickness of the inner wall of the protective wall. Attached Figure Description

The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components.

[0023] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0024] See Figures 1-2 This utility model provides a waterproof coating application tool for the inner walls of a bridge, which is applicable to the construction of the three walls of a bridge, including wall A, wall B, and a protective wall.

[0025] The waterproofing coating application tool for the three walls of the bridge consists of a block-shaped frame with a plate-shaped coating component connected to the bottom of the frame.

[0026] The width of the frame is no greater than the inner wall thickness of the three walls, so that the coating fits snugly against the inner wall of the bridge's three walls.

[0027] In this embodiment, during use, the operator first manually applies the evenly mixed paint to the area to be coated on the inner walls of the three walls for a single pre-coating. Then, the frame is attached to the steps of the three walls, ensuring the coating component adheres to the inner walls of the bridge. The operator moves the frame at a uniform speed along the extension direction of the three walls. During the movement, the plate-shaped coating component spreads the paint in the area to be coated, ensuring the paint is evenly distributed on the inner walls to form a waterproof layer. The operator moves the tooling while pre-coating the paint, allowing for continuous coating as the tooling moves. The coating component, acting as a temporary support and guide layer for the paint, maintains bidirectional contact with both the paint and the wall surface. This avoids paint buildup due to its fluidity after direct application to the wall, and the adhesion between the coating component and the inner walls ensures uniform paint thickness during transfer, preventing missed areas and effectively improving the waterproofing effect of the three walls.

[0028] Furthermore, the width of the framework is no greater than the inner wall thickness of the three walls, which avoids gaps between the framework and the wall surface caused by the coating material protruding from the wall after the framework overlaps with the three-wall steps. In addition, the bottom surface of the framework is perpendicular to the side wall of the coating material, which conforms to the design shape of the three walls.

[0029] The inventors used an analogical logic to facilitate understanding of the tool's use. Analogical logic: similar to applying putty with a scraper, the scraper (corresponding to the coating tool) needs to be in close contact with the wall, and the putty (corresponding to the paint) fills the space between the scraper and the wall. Only when the scraper moves will the putty be evenly transferred to the wall.

[0030] It should be noted that the coating is a polyurethane coating that has been uniformly mixed according to the specified ratio. The coating is a viscous fluid, and this characteristic is effective during the pre-coating process, allowing the coating to form initial adhesion between itself and the wall surface, thus providing temporary support. During pre-coating, the coating will neither flow as quickly as water nor be unable to spread as a solid. It can also be fixed to the wall surface before the tooling is applied, preventing the coating from shifting while the tooling is still in place. Consequently, when the tooling is moved subsequently, the coating can form a stable coating layer between the application tool and the inner wall of the three walls.

[0031] Understandably, the entire coating process follows the principle of "thin coats, multiple coats". The next coat is applied after the previous coat has dried. The ambient temperature during construction is 5℃-35℃ and the humidity is no more than 85%. Avoid working in rainy, snowy, or windy weather.

[0032] Optionally, the frame is square steel 1, and the surface of square steel 1 is coated with hot-dip galvanized coating.

[0033] In this embodiment, the square steel 1 with the coating can improve the corrosion resistance and wear resistance of the tooling, thereby adapting to the high humidity environment of the bridge.

[0034] Optionally, the coating component is steel plate 2, which is welded to square steel 1.

[0035] In this embodiment, welding the steel plate 2 and the square steel 1 can make the tooling an integrated structure, which is convenient to use during construction and does not require on-site assembly, thus further improving construction efficiency.

[0036] Optionally, the surface of steel plate 2 is ground to form a rough surface.

[0037] In this embodiment, grinding the surface of the steel plate 2 can enhance the adhesion of the coating and prevent coating defects caused by slippage.

[0038] Optionally, the frame is fixedly equipped with a handle for easy movement.

[0039] Optionally, the dimensions of this tooling can be selected based on actual needs. When applying the coating to wall A, the width of the frame is adapted to the inner wall thickness of wall A, allowing the coating to adhere to the inner surface of wall A. Similarly, when applying the coating to wall B, the width of the frame is adapted to the inner wall thickness of wall B, allowing the coating to adhere to the inner surface of wall B. When applying the coating to the protective wall, the width of the frame is adapted to the inner wall thickness of the protective wall, allowing the coating to adhere to the inner surface of the protective wall.

[0040] The working principle of this utility model is as follows: During use, the operator first manually applies the evenly mixed coating to the area to be coated on the inner walls of the three walls for a single pre-coating. Then, square steel 1 is overlapped at the steps of the three walls, so that steel plate 2 is in contact with the inner walls of the bridge's three walls. The operator moves square steel 1 at a uniform speed along the extension direction of the three walls. As steel plate 2 moves with square steel 1, it spreads the coating in the area to be coated, ensuring the coating is evenly distributed on the inner walls of the three walls to form a waterproof layer. The operator moves the tooling while pre-coating, allowing the coating to be continuously applied as the tooling moves.

[0041] Although the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
