Mounting and demounting method roof plate formwork support platform of concrete silo

Abstract

The invention discloses a method for mounting and detaching a top plate template supporting platform of a concrete silo, which comprises the following steps: providing an embedded part; fixing a steel corbel on the embedded part; descending a construction platform; fixing the construction platform and a silo wall (1); hanging away decomposed and detached slip forms by tools, and the like; establishing a template, a bracket and a component on a special supporting platform (3), and arranging ribs on the template; pouring concrete of a top plate (9); decomposing and detaching the template, the bracket and the component established on the special supporting platform (3); separating the special supporting platform (3) and the silo wall (1); descending the special supporting platform (3) to the bottom of the silo; and detaching the special supporting platform (3). The method for mounting and detaching the top plate template supporting platform of the concrete silo can simplify construction process, improve construction efficiency, reduce construction intensity, shorten construction period, save construction materials, and avoid potential safety hazard.

Description

technical field [0001] The invention relates to a civil engineering construction method, in particular to a method for installing and disassembling a roof formwork support platform of a concrete (round) silo. Background technique [0002] Because the concrete structure is economical, practical, easy to obtain materials, and has good moisture-proof and electrical damage-proof effects, the concrete silo structure is often used in the storage of grain and other granular items. Generally, the diameter of the silo is between 10m and 20m, the height is between 30m and 50m, and the wall thickness of the cylinder is not less than 20cm. [0003] In order to ensure the construction quality and progress of this special high-rise structure, the existing technology mostly adopts relatively mature slip-form construction technology for the construction of the silo wall of the concrete silo. Such as figure 1 As shown, the construction method is generally as follows: in the middle of the c...

AI Technical Summary

Problems solved by technology

[0005] The above construction methods have the following defects: Since the height of the silo generally exceeds 30m, the steel pipes of the fastener-type steel pipe support in the silo and the steel pipes of the support members must be closely spaced and the quantity must be large, so a large amount of steel pipes and fasteners are required. The material consumption is large, the material cost is high, and the construction process is complicated, the construction difficulty is high, the labor intensity of the construction personnel is high, the construction efficiency is low, the construction period is long, and the labor cost is high

And because the height of the roof is generally more than 30m from the ground, the vertical direction of the steel pipe is too long, and it is easy to lose stability, so there is a potential safety hazard
