Description

Technical Field

[0001] This utility model specifically relates to a metal grille structure for hanging under stairs, belonging to the field of architectural decoration technology. Background Technology

[0002] In large venues or buildings, external staircases are often built to facilitate the movement of people. Since the space is open and the bottom of the staircase is not open, a suspended ceiling is usually installed at the bottom of the staircase to improve aesthetics and safety. This is especially true in sports venues with large construction areas. Using metal grilles for suspended ceiling decoration is a relatively beautiful and economical decoration method.

[0003] For example, Chinese invention patent application CN202010033206.X provides an aluminum grid ceiling, relating to the field of building decoration technology. This aluminum alloy ceiling has low installation difficulty and low construction intensity. The aluminum grid ceiling mainly includes interconnected grid components and connecting components. The grid components are installed with their internal parts through the connecting components, which provide an installation platform for the grid components. The aluminum grid ceiling can be directly installed to the wall through the connecting components, simplifying the process and reducing installation difficulty and construction intensity. One end of the connecting component has a protrusion with a threaded hole. The connecting component is installed to the wall through the threaded hole and screws. The protrusion provides a fixed position for the connecting component, and because the connecting component is directly connected to the wall through the threaded hole and screws, the installation steps of the aluminum grid ceiling are greatly simplified, thus significantly reducing the workload of construction workers.

[0004] The aforementioned document provides an installation platform for the grid assembly by connecting components, thereby simplifying the installation process. While this does reduce installation steps when setting grids in a cross pattern, it is necessary to closely arrange the grids when installing the bottom ceiling of a staircase. Therefore, repeatedly setting up the grid assembly is a considerable amount of work. Furthermore, the bottom of the staircase has inclinations and angle changes, and traditional construction generally requires the main and secondary keel systems to be suspended by hangers, making the construction process even more complicated. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a metal grid structure for hanging under stairs, which can greatly reduce bolt drilling and welding, improve construction efficiency, and use mortise and tenon joints to fasten and fix the grid bodies together, making construction faster and more convenient.

[0006] A metal grille structure for a staircase includes an outer shell fixed to the bottom edge of the staircase. The outer shell conceals side fixing plates and assists in fixing them.

A triggering mechanism is fixedly installed on the inner wall of the U-shaped shell on the opposite side of the limiting component. A central rod located on one side of the limiting component is also fixed at the bottom of the staircase. The central rod is used to engage with the limiting component to limit movement and prevent the main body of the grille from sliding.

[0010] The limiting assembly includes a support cylinder fixed to the inner wall of the U-shaped shell. A trigger ring is rotatably engaged on the outer wall of the support cylinder. There is a pair of trigger rings. A limiting hook rod is fixed on the trigger ring in a mirror arrangement. The top end of the limiting hook rod is roughened. The bottom of each trigger ring is fixed with a limiting protrusion. There is an included angle between the limiting protrusions.

A protruding strip 205 is fixed on one side of the snap-fit ​​folding plate 203. One side of the protruding strip 205 is attached to the support rod 102. The protruding strip 205 is fixed to the support rod 102 by rivets or self-tapping screws, which can better improve the structural strength.

[0025] A limiting component 3 is fixed on the inner wall of the U-shaped shell 201 near the contact plate 202. A triggering mechanism 4 is fixedly installed on the inner wall of the U-shaped shell 201 on the opposite side of the limiting component 3. A central rod 5 located on one side of the limiting component 3 is also fixed at the bottom of the staircase. The central rod 5 is used to engage with the limiting component 3 to limit movement and prevent the grid body 2 from sliding.

[0026] The limiting component 3 includes a support cylinder 301 fixed on the inner wall of the U-shaped shell 201. A trigger ring 302 is rotatably engaged on the outer wall of the support cylinder 301. There is a pair of trigger rings 302.
