Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, and in particular to a prefabricated viewing platform. Background Technology

[0002] Currently, with the increase in arts and cultural activities, the locations and forms of these activities are becoming more and more diverse. Many event venues do not have fixed viewing platforms. Building fixed venues and stands before the event is impractical due to high costs and low utilization rates. In such cases, temporary viewing platforms are needed. Temporary viewing platforms can be assembled and disassembled. However, existing assembled and disassembled stands mostly use metal components, resulting in a high degree of fragmentation of parts. Even each step plate needs to be assembled manually, leading to low assembly and disassembly efficiency. Utility Model Content

The bottom of the multiple columns is fixed with a support base, the top of the multiple columns is provided with a diagonal brace, and a base plate is laid between adjacent diagonal braces.

[0008] In some embodiments of this application, the guardrail is a rectangular frame, with multiple round tubes evenly spaced inside the guardrail, and the top two corners of the guardrail are arc-shaped.

[0009] In some embodiments of this application, the step plate and the stair section are both made of aluminum alloy.

[0010] Compared with the prior art, this utility model has the following features and beneficial effects:

[0011] This utility model uses an installation platform to fix the grandstand passage to the grandstand, and the grandstand passage can be hoisted as a whole. The installation and disassembly of the grandstand passage are more convenient. It can be quickly installed and positioned with the installation platform through the first and second insert blocks, and fixed by assembly holes and screws to limit the displacement between the installation platform and the grandstand passage, which has strong stability. Its widespread use can produce good results. Attached Figure Description
