Construction method of large-span special-shaped curved surface concrete dome structure

Abstract

The invention relates to a construction method of a large-span special-shaped curved surface concrete dome structure, which comprises the following steps: providing a bottom template matched with the design shape of the dome structure, and supporting the bottom template at the top of a wall body corresponding to the design position of the dome structure; annular vertical reinforcing meshes with different sizes are provided, the multiple vertical reinforcing meshes are sequentially and vertically arranged on the bottom formwork at intervals in a nested mode, and an annular pouring area is formed between every two adjacent vertical reinforcing meshes; and concrete is poured into the annular pouring areas in sequence from outside to inside, and therefore the dome structure is constructed and completed. The problem that excessive concrete flows to the bottom of the bottom formwork due to one-time pouring can be avoided, the concrete can be vibrated more sufficiently by only arranging the bottom formwork, and the forming quality of the concrete is ensured.

Description

technical field [0001] The invention relates to the technical field of buildings, in particular to a construction method for a large-span special-shaped curved concrete dome structure. Background technique [0002] In recent years, Western European style and Chinese traditional architectural form have become the trend of domestic architecture. The dome is beautiful in shape, which is a combination of Chinese classical architecture and Western religious architectural style, and is favored by people. Large-span structures are mostly used in theaters, gymnasiums, exhibition halls, great halls, airport waiting halls and other large public buildings in civil buildings, large-span workshops, aircraft assembly workshops and large warehouses in industrial buildings. [0003] In the prior art, when pouring a large-span concrete dome structure, if only the bottom formwork is provided, due to the large curvature of the dome structure, the concrete will flow to the bottom of the bottom ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the defects of the prior art, and provide a construction method for a large-span special-shaped curved concrete dome structure, so as to solve the problems caused by pouring in the existing construction method. The concrete dome structure has the problem that the concrete cannot be densely combined, and it is easy to produce poor forming effects such as honeycomb pitting
