Improved shear wall formwork reinforcing method

Abstract

The invention discloses an improved shear wall formwork reinforcing method. The improved shear wall formwork reinforcing method is suitable for a shear wall with the height not larger than 6 m and the thickness not larger than 500 mm and is characterized by comprising the following steps that a, composite wood plywood is transversely laid; b, the distance between secondary edges of vertical steel pipes is 150 mm; c, the reinforcing distance between secondary lower ends is 700 mm; and d, the middle reinforcing distance takes the width of the composite wood plywood as the boundary, wherein a splicing seam of the laminated wood plywood is sealed by a wood brace of 40mm * 90mm * 3000mm from bottom to top. The improved shear wall formwork reinforcing method has the advantages that the reinforcing structure is simple, operation is easy, the construction efficiency is improved, pull screws penetrate through the wall at an abutted seam of two panels, through-wall screw holes are reduced, the concrete forming quality and the risk of water seepage blocking of the screw holes in the later period are guaranteed, the quality is guaranteed, the effect is remarkable, and the engineering cost is reduced.

Description

technical field [0001] The invention relates to a method for supporting a shear wall formwork, in particular to an improved reinforcement method for a shear wall formwork. Background technique [0002] Reinforced concrete structure is the main structural form of modern buildings or structures. Among them, shear wall is commonly used, also known as wind-resistant wall and seismic wall. It mainly bears the horizontal load and vertical load caused by wind load or earthquake. Prevents structural shear damage. With the integral pouring of walls, columns, beams, and slabs, although the quality of the concrete structure is significantly improved, the reinforcement of the shear wall formwork is often not firm, and it is easy to expand, deform, and shift, resulting in irregular concrete molding. The traditional reinforcement is assembled with wooden molds (900mm×1830mm), the panel is made of 15mm thick wood plywood, the secondary corrugation is made of 40mm×90mm wooden beams, the sp...

Problems solved by technology

[0003] However, the traditional reinforcement method is not conducive to the recycling of turnover materials, especially the sub-fluted wood and glued wood panels. After repeated use, they basically lack edges and corners, and the moment of inertia decreases. They are later used as waste wood fuel, and the initial investment cost is high.

At the same time, the entire 900mm×1830mm panel is mostly screw holes through the wall, which affects the quality of subsequent concrete molding

[0004] Therefore, there are above-mentioned inconveniences and problems in the known shear wall formwork reinforcement method
