Abstract

The invention relates to a construction method, in particular to a construction method for a support mould of a large-curvature spherical concrete structure. The technical problem of the construction of an object with a large-curvature spherical concrete structure is solved. The method comprises the following steps: firstly manufacturing an internally spherical reinforcement cage, then installing a plurality of inner templates on the surface of the internally spherical reinforcement cage and arranging square support woods and support steel pipes under the internally spherical reinforcement cage; and then manufacturing an externally spherical reinforcement cage, splicing external mould units along the circumference from the lower side to form an annule template, and then, depositing concrete till end. The method provided by the invention can effectively solve the construction problem of a spherical shell body building with the diameter less than 5m. With the adoption of the method provided by the invention, the usage amount of moulding materials is reduced, the structure is simple, the efficiency is high, the cost is saved, and the construction quality can be ensured.

Description

technical field [0001] The invention relates to a construction method, in particular to a large-curvature spherical concrete structure formwork support construction method. Background technique [0002] Nowadays, architectural design shapes are becoming more and more novel and unique, and there are more and more shapes of small-diameter spherical structures with a hemispherical diameter less than five meters in engineering. The pouring of concrete for such hemispherical buildings usually requires the manufacture of corresponding steel structures. The spherical shell serves as the mold before pouring the concrete. This construction method is clumsy, and requires custom molds, which is labor-intensive and inefficient. Contents of the invention [0003] In order to solve the technical problem of the construction of the large-curvature spherical concrete structure object, the present invention provides a large-curvature spherical concrete structure formwork support constructi...
