Adjustable steel wire rope truss device for reinforcing column formwork

Abstract

The invention discloses an adjustable steel wire rope truss device simple in structure, high in universality and maneuverability and convenient and rapid to construct, assemble and disassemble for reinforcing a column formwork. The adjustable steel wire rope truss device is free of cross-pulling screws, reduces labor and materials, and can be used for reinforcing the column formwork with various sectional sizes. The adjustable steel wire rope truss device comprises corner back edges (1) for the four corners of the column formwork (9), telescopic back edges (2) for connecting the adjacent corner back edges (1) on the four side faces of the column formwork (9), and flexible fastening connectors (3) for circumferentially connecting and fastening the corner back edges (1) and the telescopic back edges (2) to form an integral type annular truss. The depth of the telescopic back edges (2) inserted in the corner back edges (1) can be adjusted through inserted connection, and the column formwork with different lengths and widths is reinforced. The adjustable steel wire rope truss device can be widely applied to the field of building formworks.

Description

technical field [0001] The invention relates to an adjustable steel wire rope truss device used for column formwork reinforcement. Background technique [0002] With the continuous development of the construction industry, the proportion of cast-in-place concrete structures is increasing day by day. The traditional wooden formwork has low strength, less turnover times, and consumes a lot of wood and human resources; the steel formwork is heavy and difficult to demould, and the construction requires the assistance of mechanical equipment. Aluminum alloy building formwork is a new type of building formwork. It has the advantages of light weight, fast disassembly and assembly, many turnover times, low turnover cost, and clean surface of formed concrete. It has been widely concerned and applied. [0003] Generally, the columns of buildings are relatively high. During the process of pouring concrete columns, the concrete lateral pressure on the column formwork is relatively larg...

AI Technical Summary

Problems solved by technology

[0003] Generally, the columns of buildings are relatively high. During the process of pouring concrete columns, the concrete lateral pressure on the column formwork is relatively large. Due to its large deformation, it is easy to make the forming quality of the concrete columns difficult to meet the relevant requirements. Therefore, it is necessary to add reinforcements to Improve the bearing capacity of the column formwork, while trying not to affect the construction period of the formwork project

The existing back corrugations used to reinforce the column formwork are specially designed for concrete columns with specific dimensions. Due to the different types of column sections and the changes in the types of column sections on different floors, there are too many different sizes and models of column formwork reinforcement back corrugations. , so its versatility is poor, mobility is poor, the value of recycling is low, and some structures are very complicated

The existing back flute for column formwork reinforcement has to pull the screw rods in opposite directions, wasting materials and labor
