Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for building construction, specifically a working platform suitable for high-altitude installation of irregular curved trusses. Background Technology

[0002] In recent years, large-span spatial structures have been widely used in public buildings such as exhibition halls, stadiums, and train station waiting halls. Steel pipe trusses have become the mainstream structural form due to their reasonable stress distribution, light weight, and diverse shapes. However, in actual construction, for truss structures with complex shapes, arcs, or curved surfaces, it is usually necessary to prefabricate them in sections, hoist them in sections, and then weld them together at high altitude to form a whole.

[0003] In existing technologies, construction companies mostly use temporary measures such as erecting conventional scaffolding, suspended platforms, or mobile aerial work platforms to provide working surfaces. These measures have the following problems:

[0004] Poor adaptability: Conventional scaffolding is laid out in a flat plane and cannot fit the surface of irregular curved trusses, which can easily cause large gaps between the scaffolding and the components, affecting operational safety. Therefore, a working platform suitable for high-altitude installation of irregular curved trusses is proposed. Utility Model Content

[0008] To achieve the above objectives, this utility model provides the following technical solution: a working platform suitable for high-altitude installation of irregular curved trusses, comprising two horizontally parallel load-bearing structures, with several steel beams arranged along the curvature of the truss between the two load-bearing structures. The load-bearing structure includes a bottom frame structure, which is formed into a rectangle by welding two steel rods one and two steel rods two. Support pipes one are symmetrically arranged at the front bottom corner of the bottom frame structure, and support pipes two are symmetrically arranged at the rear bottom corner of the bottom frame structure. The height of the support pipes two is greater than that of the support pipes one. A diagonal frame rod is detachably connected between the support pipes one and two.

[0009] As a further preferred embodiment of this utility model, the inclined support rod is long and narrow, with its front and rear ends inserted into the inner sides of the first and second support tubes. The tops of the two first support tubes are connected to the first reinforcing plate, and the tops of the two second support tubes are connected to the second reinforcing plate.

[0013] (III) Beneficial Effects

[0014] This utility model provides a working platform suitable for high-altitude installation of irregular curved trusses. It has the following beneficial effects:

[0015] High adaptability: The inclined frame and steel beam structure are arranged according to the curvature of the truss, and the platform fits closely with the irregular curved truss, reducing the working gap and improving the installation accuracy.
