Aluminum profile with fillet at internal corner

Abstract

This utility model relates to an internal corner rounded aluminum profile, including a rounded triangular piece and a rounded side strip. The two sides of the triangular piece connect to the side strip, and a vertical extension piece extends upward from the top edge of the triangular piece. The triangular piece and the extension piece are integrally formed. Fixing pieces extending towards the back are provided on both sides of the extension piece, and the extension piece is fixedly connected to the wall via the fixing pieces. The internal corner rounded aluminum profile provided by this utility model features an extension piece at the top of the triangular piece, designing the two as an integral structure. The triangular piece is fixed and supported by the fixing pieces on the back of the extension piece to the wall. This eliminates the need for a support on the back of the triangular piece to fix it at the corner, avoiding the problem of insufficient support from a single triangular piece, which can cause the triangular piece to dent inward when pressed.

Description

Technical Field

[0001] This utility model belongs to the field of cleanroom construction technology, and specifically relates to aluminum profiles with rounded internal corners. Background Technology

[0002] To ensure a clean production environment, cleanrooms need to minimize contamination. However, recessed corners, where walls and floors meet, create dead spaces where dirt and grime easily accumulate and are difficult to clean. The narrow angles prevent conventional cleaning tools (such as brooms and mops) from fully reaching the bottom, and water stains easily remain in these corners, mixing with dust to form grime. Prolonged dampness can also lead to mold, blackening, and bacterial growth. Therefore, aluminum profiles are used to round off the corners of cleanrooms, and PVC flooring is used to cover them. Especially at the corner bends, individual triangular brackets need to be installed. If these brackets are not properly secured, they can dent, affecting structural strength. Utility Model Content

[0003] In view of this, the purpose of this utility model is to address the shortcomings of the existing technology by providing an aluminum profile with rounded corners that can ensure that the triangular pieces at the corners do not dent without the need for additional auxiliary supports.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The rounded aluminum profile for inside corners includes a rounded triangular piece and a rounded side strip. The two sides of the triangular piece are connected to the side strip. The top edge of the triangular piece extends upward to a vertical extension piece. The triangular piece and the extension piece are integrally formed. Both sides of the extension piece are provided with fixing pieces extending to the back. The extension piece is fixedly connected to the wall through the fixing pieces.

[0006] To better realize this utility model, the above structure is further optimized by bonding and fixing the fixing piece to the wall.

[0007] To better realize this utility model, the above structure is further optimized by including a fixing strip, on which a first buckle component is provided, and on the back of the side strip a second buckle component is provided, and the second buckle component is buckled to the first buckle component.

[0008] To better realize this utility model, the above structure is further optimized. The fixing strip includes a base plate and two side plates symmetrically arranged on both sides of the base plate. The included angle between the two side plates is a right angle, and the two side plates are fixedly connected to the two side walls at the inside corners respectively.

[0009] To better realize this utility model, further optimizations are made to the above structure. The first buckle component consists of two symmetrically arranged snap-fit ​​strips, which are respectively located at the corners of the base plate and the two side plates. The second buckle component consists of two symmetrically arranged insert strips, which are inserted from the inside of the two snap-fit ​​strips and abut against the corners.

[0010] Compared with the prior art, this utility model has the following advantages:

[0011] The rounded aluminum profile for inside corners provided by this utility model has an extension piece set on the top of the triangular piece, and the two are designed as an integrated structure. The fixed support of the triangular piece is achieved by fixing the fixing piece on the back of the extension piece to the wall. It is not necessary to install a support on the back of the triangular piece to fix the triangular piece at the corner, thus avoiding the problem that the individual triangular pieces have insufficient support and the triangular pieces will dent inward when pressed.

[0021] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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 mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] Please refer to Figures 1-4 The present invention provides an arc-shaped aluminum profile for internal corners, comprising an arc-shaped triangular piece 1 and an arc-shaped side strip 2. The two sides of the triangular piece 1 are connected to the side strip 2, and the top edge of the triangular piece 1 extends upward with a vertical extension piece 3. The triangular piece 1 and the side strip 2 together form an arc transition structure used at the internal corner of a cleanroom. The side strip 2 is used for the angle between the wall and the ground, and the triangular piece 1 is used for the angle at the internal corner.

[0023] This application designs the triangular piece 1 and the extended piece 3 as a single integral molding, and the height of the extended piece 3 can be designed according to actual usage. For example, the height can be appropriately reduced due to uneven ground, and it can be cut and trimmed on-site as needed. Both sides of the extended piece 3 are provided with fixing plates 301 extending towards the back. The extended piece 3 is fixedly connected to the wall via the fixing plates 301, and structural adhesive can be used for bonding and fixing. By fixing the fixing plates 301 on the back of the extended piece 3 to the wall, the triangular piece 1 is fixedly supported. It eliminates the need for a support on the back of the triangular piece 1 to fix it at the corner, avoiding the problem of insufficient support for a single triangular piece 1, which could cause the triangular piece 1 to dent inward when pressed.

[0024] The side strip 2 is relatively long and requires a fixing strip 4 for support and fixation. The fixing strip 4 is equipped with a first buckle assembly 5, and a second buckle assembly 6 is located on the back of the side strip 2. The second buckle assembly 6 is connected to the first buckle assembly 5 via a snap-fit ​​connection, making installation quick and convenient. The fixing strip 4 includes a base plate 401 and two side plates 402 symmetrically arranged on both sides of the base plate 401. The angle between the two side plates 402 is a right angle. The two side plates 402 are fixedly connected to the walls on both sides at the internal corners, providing support. The first buckle assembly 5 consists of two symmetrically arranged snap-fit ​​strips, located at the corners of the base plate 401 and the two side plates 402. The second buckle assembly 6 consists of two symmetrically arranged insert strips, inserted from the inside of the two snap-fit ​​strips and abutting against the corners. By utilizing the corners, the pressure applied to the side strip 2 is transferred to the wall through the buckle assembly, thereby improving the structural strength of the side strip 2. Even under significant pressure, the side strip 2 and the fixing strip 4 will not deform.

[0025] When installing in combination, such as Figure 1 As shown, the rounded aluminum profile at the inside corner is installed at the inside corner of the cleanroom and fixed firmly. When laying the PVC plastic floor, the rounded transition structure at the inside corner is directly covered and hidden. The PVC plastic floor is flipped up about 10cm on the wall, resulting in a neat and beautiful appearance.

[0026] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
