Abstract

The invention discloses a high-altitude large-span cantilever structure construction platform and method. The construction platform comprises a concrete structure, a stand column pre-buried in the concrete structure, a parallel chord truss arranged on the stand column, an upper chord secondary beam arranged on a truss upper chord, a lower chord secondary beam arranged on a truss lower chord, and acontour plate or a supporting formwork arranged on the upper chord secondary beam. The construction platform can be used as the high-altitude cantilever concrete structure construction platform, andis particularly suitable for the situations of large suspension height, large span and large construction load. The construction platform is simple in structure and convenient to construct and install, the construction problem of the high-altitude large-span cantilever structure can be effectively solved, the construction method saves materials, the danger of high-altitude operation is reduced, the construction difficulty and the construction safety risk are reduced, meanwhile, cross operation with surrounding structures is avoided, and the construction efficiency of the high-altitude large-span cantilever structure is improved.

Description

technical field [0001] The invention belongs to the technical field of design and construction of building structures, and in particular relates to a construction platform and method for a high-altitude and large-span suspension structure. Background technique [0002] A cantilever structure is a suspended structure that protrudes outward from the structure. Generally speaking, the height and span are not large, and the self-weight is also small. However, due to the special process and layout requirements, nuclear power plants and other industrial structures appear high-altitude and large-span cantilevered concrete structures with large suspension heights, large spans, and self-heavy weight. For this kind of structure, due to the lack of construction platform, it is generally considered to use full hall scaffolding, cantilevered scaffolding, triangular braces, etc. to build temporary construction platforms; however, cantilevered scaffolding and triangular braces cannot be us...
