Abstract
本发明涉及一种施工方法，具体为一种大曲率球形混凝土结构支模施工方法。解决大曲率球形混凝土结构物体的施工的技术问题，首先制作内球形钢筋笼，然后将若干内模板单元安装在内球形钢筋笼表面，在内球形钢筋笼下面设置支撑方木和支撑钢管；然后再制作外球形钢筋笼，然后从下侧开始，环周向拼接外模板单元，拼接形成一个环带模板，然后浇注混凝土，直至全部浇注完成。本发明所述方法可以有效解决直径小于五米的球形壳体建筑的施工的问题，制模用料少，结构简单，效率高，节约了成本，而且施工质量可以得到保证。
The invention relates to a construction method, in particular to a large-curvature spherical concrete structure formwork support construction method. To solve the technical problems of the construction of large-curvature spherical concrete structure objects, first make the inner spherical reinforcement cage, then install several inner formwork units on the surface of the inner spherical reinforcement cage, and set the supporting square timber and supporting steel pipes under the inner spherical reinforcement cage; then Make the outer spherical reinforcement cage, and then splice the outer formwork units circumferentially from the lower side to form a ring-shaped formwork, and then pour concrete until all the pouring is completed. The method of the invention can effectively solve the construction problem of the spherical shell building with a diameter of less than five meters, and has the advantages of less molding material, simple structure, high efficiency, cost saving, and construction quality can be guaranteed.
Description
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.
