Description

Technical Field

[0001] The utility model relates to a wall-mounted stair railing handrail fixing structure. Background Art

[0002] Glass railings can be seen everywhere in real life. In the current construction industry, the handrails of wall-mounted stairs are fixed to the wall using embedded parts, and then the connecting parts are welded. Finally, the railings and fixed components are welded after the decorative panels are installed. However, this fixing method requires the connecting parts to be installed before the wall aluminum plate is installed, and it is impossible to accurately achieve the length and size of the connecting parts and the interlacing of the processes.

[0003] This process cannot accurately install the dimensions of the connectors, and when the angles of the stair railings are inconsistent, the installation length cannot be determined. The angles of the embedded parts and connectors during installation are very strict. If any angle deviation occurs, the aluminum plate will not be able to fix the handrail, and rework will be required. The aluminum wall panels must be laid out and punched in the processing plant. If there is an error in the hole position, accurate installation is impossible and the desired effect will not be achieved after installation.

[0004] Conventional installation methods have requirements for the installation sequence of the process. The wall decoration panels must be installed after the pre-installation is completed, and finally the connectors and angle brackets are welded. If the wall decoration panels are aluminum plates, the finished aluminum plates will be damaged during welding, and the finished products cannot be protected. The construction period cannot be guaranteed and the construction flexibility is poor. Therefore, a wall-mounted stair railing handrail fixing structure is proposed to address the above problems.

In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] like Figure 1-4 As shown, a wall-mounted stair railing fixing structure includes a connector 1, an expansion bolt 2, a second bolt 3, and a steel angle bracket 4. One end of the connector 1 is connected to the concrete wall 5 via the expansion bolt 2; the other end is connected to the second bolt 3, which passes through the decorative panel 6 and connects to the steel angle bracket 4, which is then connected to the railing 7. Both the connector 1 and the steel angle bracket 4 are made of stainless steel.

[0021] Specifically, the connector 1 is a square hollow tube. The inner wall of the connector 1 is connected to the first nut 8, which is connected to the expansion bolt 2 through the first nut 8; the outer wall on the other side of the connector 1 is connected to the second nut 9, and the second bolt 3 is connected to the connector 1 through the second nut 9. The first nut 8 and the second nut 9 are welded to the connector 1. The connector 1 uses a 50mm*50mm*50mm cube, which is welded from 50mm wide and 3mm thick flat iron. There is no flat iron welded on the upper and lower sides of the cube, and flat iron is welded on the other four sides. Holes are opened in the center of the flat iron on the front and back, and A12mm nuts (first nut 8 and second nut 9) are welded on the front, and only holes are opened on the back.

[0022] Specifically, the connecting member 1 is located on the inner side of the decorative panel 6; the second bolt 3 located on the outer side of the decorative panel 6 is sleeved with a gasket 10, a third nut 11 and an outer decorative cover 12, the gasket 10 is tightly attached to the outer wall of the decorative panel 6 through the third nut 11, and the outer decorative cover 12 covers the gasket 10 and the third nut 11.

[0023] Specifically, expansion bolts 2 are used to secure connector 1 to concrete wall 5. After decorative panel 6 is installed, a hole is drilled on-site in the decorative panel 6 at the location corresponding to connector 1. The hole is 2mm larger than the diameter of connector 1. One end of a second bolt 3 is connected to a steel angle bracket 4. A washer 10 with an inner diameter of 14mm, an outer diameter of 30mm, and a thickness of 2mm is added to the second bolt 3. The other end of the second bolt 3 is connected to the second nut 9 of connector 1. A third nut 11 is added to the outside of washer 10, near the steel angle bracket 4, to secure the steel angle bracket 4 and adjust its angle. An outer decorative cover 12 is installed on the outside of the third nut 11.

[0024] This wall-mounted stair railing handrail fixed structure is simple to operate and does not affect the layout of wall decorative panels. The angle of the steel angle code can be adjusted at will. The connectors are mechanically connected to each other, the installation quality is guaranteed, and the work efficiency is high. The decorative panels can be installed after the connectors are installed, which can save construction time. Compared with traditional processes, the construction process is reduced, thereby reducing the labor input, saving labor, and further reducing construction costs.

[0025] The connector 1 is made of stainless steel and is fixed to the concrete wall 5 by a mechanical structure, which ensures the quality of raw materials and facilitates construction. The types and amounts of materials used are reduced, saving on material costs and retesting fees, thus reducing costs.

[0026] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
