The new building formwork reinforcement system, also known as the “new shear wall formwork support system”, is independently developed and produced by Changli County Tiangang Structure Sales Co., Ltd. It has the advantages of light weight, simple operation, light load, and frequent number of passes. It greatly reduces the labor intensity of workers' construction work. It is the first manufacturer in China to break through the traditional "wood side + steel pipe" formwork reinforcement process, and is the key technical measure to realize the shear wall free painting.

The principle and advantages of the new building formwork reinforcement system are mainly reflected in the advantages of high load strength, high rigidity and small deformation. The horizontal main keel is usually 9-way reinforcement, 5 reinforcement, and 3 reinforcement, of which Nantong Erjian Group 3 The main keel reinforcement process is the most mature. By reasonably setting the vertical square steel spacing, the number of transverse main keels is reduced. Through mechanical calculation and engineering practice, the shearing wall formwork three main keel reinforcement system can withstand the shear wall pouring process. And the side pressure after pouring.

The horizontal horizontal "standardized steel support" main keel components are composed of wall bars, L-bars, male angle locks, hole locks, transverse joints, and diagonal supports. The materials are all cold-rolled Q235 "C-type" strip series.

(1) Wall bar: 60mmX50mm "C-type" cold-rolled strip, wall thickness 2.75, weight 4.2Kg per meter, cross-section resistance moment W = 20.80 cubic centimeters. Function: It is used for lateral reinforcement of shear wall instead of steel pipe. Advantages: increase the vertical keel force area of ​​the building formwork, overcome the natural phenomenon of rising mold, uniform specifications, connect the positioning round hole on the side, convenient connection and assembly, and light weight Easy to operate and improve work efficiency.

(2) L-shaped bar: It consists of two short bars welded with the material of the horizontal bar, with an angle of 90 degrees. Function: It is used for horizontal reinforcement at the corner of the short-supported shear wall. Advantages: It can ensure the square corner of the shear wall and form a square square. It can be used with the wall bar to make the connection fast and easy to operate.

(3) Hole lock: consists of a short bar and two hook bolts. Function: It is used for template reinforcement of shear wall hole; Advantages: Use two hook bolts to hook the positioning hole on the horizontal bar to quickly tighten the short horizontal bar. By tightening the bolt, the verticality of the hole can be adjusted, and the hole can be quickly completed. Reinforcement of the template.

(4) Yang angle lock: consists of bolt, C-lock and reinforced top wire. Function: It is used for the reinforcement of the shear angle of the wall; Advantages: It can quickly complete the reinforcement of the positive angle by using one pin and one top, effectively avoiding the problem of loose deformation in the traditional shear wall reinforcement, and ensuring the positive angle of the positive angle. Slurry.

(5) Horizontal bar connector: It consists of a square steel pipe and two bolts. Acting on the positioning bar of the horizontal bar of the wall, quickly connecting the horizontal bar to ensure that the connecting point of the horizontal bar does not open the tension of the two ends; Advantages: It can ensure the integrity of the horizontal bar of the wall and avoid the phenomenon of rising mode.

(6) Oblique support: Through the adjustment of the screw rod, the top can be pulled and the verticality of the shear wall can be better controlled.

The structure of the new building formwork reinforcement system consists of two major parts: the (vertical vertical) secondary back and the (horizontal horizontal) main keel. The vertical secondary squat adopts small square steel instead of the traditional square wood, and the horizontal main keel adopts “new standard steel support of Changli Tianjian Industrial Factory” instead of the traditional steel pipe reinforcement. Changli Tianjian Industrial Factory, after years of technical research, the new standardized steel support (main keel) has been upgraded to the 4th generation.
