Light steel keel type corner wall formwork reinforcing system

Abstract

The invention discloses a light steel keel type corner wall formwork reinforcing system. Holding type fastening on corner wall formwork vertical back edges is formed through multiple back edge reinforcing frames which are vertically distributed at intervals; each back edge reinforcing frame comprises multiple transverse bars; the front end of one transverse bar in the two adjacent transverse barsat each corner is connected to the side face of the other transverse bar in an abutting manner, and every two adjacent transverse bars which are connected in an abutting manner are fixedly connected to be in a perpendicular state through a right angle ensuring device; except inner wall corners, every two adjacent transverse bars which are perpendicular to each other are reinforced through an angleopposite-pulling device; every two parallel transverse bars are pull-pressed and locked through a parallel opposite-pulling device; each right angle ensuring device comprises a right-angle-shaped angle iron body, and the two right-angle edges of each right-angle-shaped angle iron body are fixedly attached to the outer side faces of the corresponding transverse bar through a first T-shaped bolt and a locking nut which are arranged in a penetrating manner; and preferably, each transverse bar is composed of two pieces of parallel C-shaped light steel. The light steel keel type corner wall formwork reinforcing system has the beneficial effects that the reinforcing frames are good in right angle ensuring performance and overall rigidity and high in strength; building and disassembling operation is convenient, and the building and disassembling efficiency is high; and in addition, no hidden danger of damaging other components occurs in the turnover process, and the construction cost is low.

Description

technical field [0001] The invention relates to a formwork reinforcement system, in particular to a light steel keel type corner wall formwork reinforcement system. Background technique [0002] In the process of building construction, it is necessary to use formwork to erect supporting columns or mold cavities for walls, and the formwork is fastened and fixed by a reinforcement system composed of a reinforcement frame with a vertical back corrugation. In order to meet the requirements of modern construction, the reinforced frame not only needs to have sufficient strength to provide safety protection, but also should be easy to disassemble and assemble for repeated use, thereby reducing construction costs. The existing reinforcement system for corner wall formwork is usually reinforced by tensioning the horizontal bars, and the reinforcement methods include wedge locking, half-pull or oblique tension and so on. However, the two adjacent horizontal bars in the existing reinf...

Problems solved by technology

However, the two adjacent horizontal bars in the existing reinforced frame do not form an abutting relationship, or the abutting surface is limited to the section of the horizontal bar, and it is difficult to ensure that the adjacent horizontal bars are perpendicular to each other during the fastening process, or the operating space for the pull is limited. It is easy to make it difficult to guarantee the verticality of the two formwork surfaces that should be perpendicular to each other in the corner wall formwork, resulting in irregular shape of the wall after pouring
