Description
Technical Field
[0001] This utility model belongs to the field of building construction technology, specifically relating to an auxiliary tool for plastering external corners. Background Technology
[0002] The trowel is the most common and widely used traditional plastering tool in current construction. Due to its simple structure, convenient operation, and low price, it has been used to this day and remains one of the main tools for plastering operations in my country.
[0003] However, most existing plastering tools are flat, which is very inconvenient when plastering external corners (referring to protruding corners on the wall, such as the four protruding corners of the exterior of a building and the angle between door and window openings and the wall). Multiple back-and-forth plastering steps are required to complete the task. This not only reduces construction efficiency but also results in poor plastering quality, specifically decreased flatness and verticality of the external corner plaster, leading to a low rate of acceptable measured values for external corners. Furthermore, the overall strength of these plastering tools is not high, making them prone to deformation during plastering and resulting in poor plaster flatness. Utility Model Content
[0004] The purpose of this utility model embodiment is to provide an auxiliary tool for plastering external corners, which aims to solve the problems of low construction efficiency, poor plastering effect and low overall strength of existing plastering tools when plastering external corners.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: An auxiliary tool for plastering external corners includes a handle, a first plate, a second plate, a support frame, and a rib plate. One end of the support frame is fixedly connected to the handle, and the other end of the support frame is fixedly connected to the first plate and the second plate respectively. The first plate and the second plate are connected and integrally formed. A groove for inserting an external corner is formed between the first plate and the second plate. The groove is away from the support frame. The included angle between the first plate and the second plate is 90°, and the included angle between the first plate and the second plate protrudes towards the support frame. The reinforcing plate is fixedly connected to the side of the first plate near the support frame and the side of the second plate near the support frame.
[0006] As a preferred embodiment, the upper edges of the first plate and the second plate, as well as the lower edges of the first plate and the second plate, are all connected to the reinforcing plates.
[0007] As a preferred embodiment, the reinforcing plate is fixedly connected to the middle of both the first plate and the second plate.
[0008] As a preferred embodiment, the reinforcing plate includes a first rib and a second rib integrally connected to each other; the first rib is fixedly connected to the first plate, and the second rib is fixedly connected to the second plate.
[0009] As a preferred option, the first rib and the second rib are configured in an L-shaped structure.
[0010] As a preferred embodiment, the handle is cylindrical, and the axis of the handle is parallel to the first plate and the second plate.
[0011] As a preferred embodiment, the support frame is welded and fixed to the handle, the first plate, and the second plate, respectively.
[0012] As a preferred embodiment, the support frame has two components, which are spaced apart from each other.
[0013] As a preferred embodiment, each of the support frames includes a first support member and a second support member, one end of the first support member is welded and fixed to the first plate, the other end of the first support member is welded and fixed to the handle, one end of the second support member is welded and fixed to the second plate, and the other end of the second support member is welded and fixed to the handle.
[0014] As a preferred embodiment, the handle, the first plate, the second plate, the support frame, and the reinforcing plate are all made of steel.
[0015] Compared with the prior art, the beneficial effects of this utility model embodiment are as follows: This invention utilizes a 90° angle between the first and second flat plates to form a 90° groove. This groove allows for easy right-angle plastering of external corners by inserting the corner piece through the first and second flat plates, resulting in high construction efficiency and excellent plastering effect. Furthermore, the addition of ribs to the first and second flat plates enhances their strength and connection stability, thereby improving overall strength and ensuring a smooth plastering finish at the external corners.

[0020] See Figure 1 and Figure 2 As shown in the figure, this utility model embodiment provides an auxiliary tool for external corner plastering. The auxiliary tool includes a handle 1, a first plate 2, a second plate 3, a support frame 4, and a reinforcing plate 5. One end of the support frame 4 is fixedly connected to the handle 1, and the other end of the support frame 4 is fixedly connected to the first plate 2 and the second plate 3 respectively. The first plate 2 and the second plate 3 are connected and integrally formed. A groove 6 for inserting an external corner is formed between the first plate 2 and the second plate 3. This groove 6 faces away from the support frame 4, and the included angle between the first plate 2 and the second plate 3 is 90°, with the included angle protruding towards the support frame 4. By gripping the handle 1 and using the 90° groove 6 formed between the first plate 2 and the second plate 3 for inserting the external corner, it is possible to conveniently perform right-angle plastering on the external corner using the first plate 2 and the second plate 3. This results in high construction efficiency and excellent plastering effect, improving the flatness and verticality of the external corner plastering, thereby increasing the measured pass rate of the external corner.
[0021] In some embodiments, the rib plate 5 is fixedly connected to the side of the first plate 2 near the support frame and the side of the second plate 3 near the support frame. This can improve the strength of the first plate 2 and the second plate 3, and improve the stability of the connection between the first plate 2 and the second plate 3, thereby improving the overall strength. This makes it less likely for the first plate 2 and the second plate 3 to deform when plastering the external corner, and improves the flatness of the plaster.
[0022] In some embodiments, the upper and lower edges of the first plate 2 and the second plate 3 are both connected to the reinforcing plate 5, and the middle portions of the first plate 2 and the second plate 3 are both fixedly connected to the reinforcing plate 5. In this embodiment, the distance from the reinforcing plate 5 in the middle portion of the first plate 2 to the reinforcing plate 5 at the upper end of the first plate 2 is equal to the distance from the reinforcing plate 5 in the middle portion of the first plate 2 to the reinforcing plate 5 at the lower end of the first plate 2, so as to further improve the stability of the connection between the first plate 2 and the second plate 3 and greatly improve the overall strength of the corner plastering auxiliary tool. Specifically, the reinforcing plate 5 includes a first rib 51 and a second rib 52 integrally connected to each other; the first rib 51 is fixedly connected to the first plate 2, and the second rib 52 is fixed to the second plate 3, and the first rib 51 and the second rib 52 are configured in an L-shaped structure.
[0023] In some embodiments, the handle 1 is cylindrical, and the axis of the handle 1 is parallel to the first plate 2 and the second plate 3, so as to facilitate gripping the handle 1 for plastering operations.
[0024] In some embodiments, there are two support frames 4, which are spaced apart from each other. The support frames 4 are welded and fixed to the handle 1, the first plate 2, and the second plate 3, respectively, to improve the connection stability of each component. The handle 1, the first plate 2, the second plate 3, the support frame 4, and the reinforcing plate 5 are all made of steel to improve overall stability. Specifically, each support frame 4 includes a first support member 41 and a second support member 42. One end of the first support member 41 is welded and fixed to the first plate 2, and the other end of the first support member 41 is welded and fixed to the handle 1. One end of the second support member 42 is welded and fixed to the second plate 3, and the other end of the second support member 42 is welded and fixed to the handle 1.
[0025] In summary, this utility model utilizes the 90° angle between the first plate 2 and the second plate 3 to form a 90° groove 6 between them. This allows for convenient right-angle plastering of the external corner by inserting the external corner into the groove 6, resulting in high construction efficiency and excellent plastering effect. Furthermore, the reinforcement plate 5, fixed to the first plate 2 and the second plate 3, enhances the strength of the first plate 2 and the second plate 3 and improves the stability of their connection, thereby increasing the overall strength and ensuring a smooth plastering surface at the external corner.
[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
