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

Deep camber spherical concrete structure formwork construction method
Technical field
The present invention relates to a kind of job practices, be specially a kind of deep camber spherical concrete structure formwork construction method.
Background technology
Architectural design moulding is now more and more new and original, the moulding that half bulb diameter occurring in engineering is less than the minor diameter spherical structure of five meters also gets more and more, the spherical shell that this hemispherical building fluid concrete normally will produce corresponding steel work is as mould, and then fluid concrete.This job practices is more clumsy, and needs custom mold, the expense of taking a lot of work material, and efficiency is low.
Summary of the invention
The present invention, in order to solve the technical problem of the construction of deep camber spherical concrete structure object, provides a kind of deep camber spherical concrete structure formwork construction method.
The present invention is realized by following technical scheme, a kind of deep camber spherical concrete structure formwork construction method, first utilize warp-wise reinforcing bar and broadwise reinforcing bar to intersect and fix spherical reinforcing cage in making, two adjacent broadwise reinforcing bar distances are 500-800mm, then adopt five-ply board or bamboo plywood, be cut into wide 200mm, the inner formword unit of long 2000-3000mm, then by some inner formword cellular installations in interior spherical surface of reinforcing cage, inner formword unit and broadwise reinforcing bar diagonal cross, and connect by steel wire; Below interior spherical reinforcing cage, supporting square timber and supporting steel pipe are set; And then utilize warp-wise reinforcing bar and broadwise reinforcing bar to intersect and fix making outer spherical reinforcing cage, two adjacent broadwise reinforcing bar distances are 500-800mm, then adopt five-ply board or bamboo plywood, be cut into wide 200mm, the exterior sheathing unit of long 2000-3000mm, then from downside, ring is splicing exterior sheathing unit circumferentially, is spliced to form endless belt template, then a fluid concrete, until whole casting completes are provided with connecting screw rod between inner formword and exterior sheathing.After concrete setting, form removal, can form spherical concrete structure.
Compare with there being technology, the method for the invention can effectively solve the problem of construction that diameter is less than the spherical shell building of five meters, and the method for the invention molding materials are few, simple in structure, and efficiency is high, has saved cost, and construction quality can be guaranteed.
