Detailed Description

A truss wallboard for making shear force wall include concrete slab 1, parallel arrangement multiunit steel bar truss on concrete slab 1, each steel bar truss all includes

last string muscle

2, 2 both sides of last string muscle set up

web muscle

3, 3 lower parts of web muscle are pre-buried in

concrete slab

1, 2 one end of last string muscle are located outside concrete slab 1, the 2 other ends of last string muscle flush with concrete slab 1. The upper chord ribs 2 can be used as longitudinal steel bars of the shear wall, so that the steel bars of the upper and lower wall boards are overlapped, the steel bars do not need to be penetrated and fixed additionally when the shear wall is manufactured, the construction steps are simplified, the steel bar truss can improve the rigidity and the compression resistance of the wall body, and the probability of damage of the wall boards in construction and transportation is reduced.
