Description
Technical Field
[0001] This utility model belongs to the field of building construction technology, specifically relating to an auxiliary tool for plastering inside 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 inside corners (recessed corners on the wall, also called interior corners, such as the four corners of a room). Multiple back-and-forth plastering passes are required to complete the job. This not only reduces construction efficiency but also results in poor plastering quality, specifically decreased flatness and verticality of the inside corner plaster, leading to a low rate of acceptable measurements for inside 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 inside corners, which aims to solve the problems of low construction efficiency, poor plastering effect and low overall strength of existing plastering tools when plastering inside corners.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A corner plastering auxiliary tool 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. 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 is away from the support frame to form a protrusion for matching the corner. 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 first plate, the ribbed plate, and the second plate together form a recess, and the support frame and the handle are disposed in the recess.
[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 protrusion formed between the first and second plates, away from the support frame, and creates a 90° angle between them. This allows for convenient right-angle plastering of the inside corner by inserting the protrusion into the groove formed by the inside corner, resulting in high construction efficiency and excellent plastering effect.

[0020] See Figure 1 and Figure 2 As shown in the figure, this utility model embodiment provides an auxiliary tool for plastering inside corners. This 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, with an included angle of 90° between them. A protruding portion 6, formed by the protruding portion 6 between the first plate 2 and the second plate 3 and extending away from the support frame 4, is provided to match the inside corner. By gripping the handle 1 and inserting the protruding portion 6 into the groove formed by the inside corner, right-angle plastering can be easily performed on the inside corner using the first plate 2 and the second plate 3. This method has high construction efficiency and excellent plastering effect, improving the flatness and verticality of the inside corner plastering, thereby increasing the measured pass rate of the inside 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 inside corners, and improves the flatness of the plastering.
[0022] In some embodiments, the first plate, the rib plate 5, and the second plate 3 together form a recessed portion, and the support frame 4 and the handle 1 are disposed in the recessed portion 7 to effectively utilize space and make the structure compact.
[0023] 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 to further improve the overall strength of the first plate 2 and the second plate 3 and the stability of their connection, thereby greatly improving 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 fixedly connected to the second plate 3. The first rib 51 and the second rib 52 are configured in an L-shaped structure so that they can match the L-shaped structure formed by the first plate 2 and the second plate 3.
[0024] 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.
[0025] 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.
[0026] In summary, this utility model utilizes a protrusion 6 formed between the first plate 2 and the second plate 3, away from the support frame 4, and makes the included angle between the first plate 2 and the second plate 3 90°. This allows for convenient right-angle plastering of the inside corner by inserting the protrusion 6 into the groove formed by the inside corner when plastering. The construction efficiency is high and the plastering effect is excellent. Secondly, the reinforcement plate 5 fixed to the first plate 2 and the second plate 3 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 and the flatness of the inside corner plastering.
[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
