A construction method for reverse installation of a hanging steel structure

Abstract

The invention discloses an inverted mounting and constructing method for a hanging type steel structure. The inverted mounting and constructing method for the hanging type steel structure comprises the following steps: arranging an embedded structure of the hanging type steel structure in a process of constructing a main body concrete structure of the hanging type steel structure; erecting a temporary supporting structure in the constructed main body concrete structure; and constructing a temporary supporting surface at a position below a main steel beam of the hanging steel structure; assembling a main steel beam and a hanging pillar; hoisting the main steel beam and the hanging pillar which are assembled to the temporary supporting surface, and fixing an end of the main steel beam with the embedded structure; hoisting the hanging type steel structure layer by layer from top to bottom at a position below the main steel beam and the hanging pillar, and fixing the end of the hanging type steel structure by the embedded structure after the different layers of the hanging type steel structure is hoisted in place; finishing hoisting and fixing of all the layers of the hanging steel structure; and disassembling the temporary supporting structure. BIM simulation analysis, ultra-high supporting and inverted vertical crossing construction are implemented, problems can be pre-analyzed and treated, construction quality is guaranteed, the costs are reduced, and the construction period is shortened.

Description

technical field [0001] The invention relates to the construction field of steel structure building systems, in particular to a method for reverse installation and construction of a bottom-hanging steel structure. Background technique [0002] With the development of the national economy and the diversification of architectural design, more and more space special-shaped steel truss structures are used in various large-scale stadium buildings. It has been developed from the ground to be installed on the roof of the concrete building, and it is cross-constructed with other professions. The space available for hoisting is very small, and the conventional hoisting process cannot solve such problems. [0003] At present, during the construction of steel truss structure buildings, it is difficult to lift the steel truss from bottom to top. Under the condition of narrow space, it cannot be hoisted directly on the reinforced concrete structure floor, and the arc-shaped main truss is ...

[0002] With the development of the national economy and the diversification of architectural design, more and more space special-shaped steel truss structures are used in various large-scale stadium buildings. Developed from the ground to be installed on the roof of the concrete building, cross-construction with other professions, the space available for hoisting is very small, and the conventional hoisting process cannot solve such problems

[0003] At present, during the construction of steel truss structure buildings, it is difficult to lift the steel truss from bottom to top. Under the condition of narrow space, it cannot be hoisted directly on the reinforced concrete structure floor, and the arc-shaped main truss is laterally stable during the hoisting process. It is not easy to control; high-altitude assembly and welding operations and three-dimensional crossing operations are large, requiring a large number of mechanical shifts and supporting tire frames, which are high in cost and low in efficiency; when the segmented truss is lifted and installed, the lateral stability of the arc-shaped main truss is difficult to control ; The problem of easy deformation and instability during the hoisting of multi-level steel trusses
