The concrete poured inside has a reliable mechanical engagement effect with the surface, and the concrete and the EPS can work cooperatively. The binding force of the anti-crack mortar or concrete and EPS is improved, the module cannot be damaged due to collision of sharp corners in the transportation process, and meanwhile, the demoulding is convenient and the binding force is improved.

Optionally, in the two second dovetail grooves 280 on the inner surfaces of the two L-shaped templates 200, two oppositely-arranged insert plates are arranged in the two second dovetail grooves 280, and the insert plates divide a pouring cavity enclosed by the two L-shaped templates 200 into a concrete pouring cavity and a sediment pouring cavity. Concrete and silt are poured at intervals, so that the economical efficiency is better. Irregular columns with any size can be formed, as shown in figures 1 to 3, reinforced concrete can be poured into the irregular columns, heat-insulating mortar or common mortar is poured outside the split areas of the inserting plates, and the manufacturing cost can be effectively reduced (each cube of the mortar is about 40% of the manufacturing cost of the concrete). The safety is ensured, and the beam column is not exposed.

Alternatively, referring to fig. 1 to 3, the connecting member 300 includes a first connecting member 310 and a second connecting member 320. The first and

second connectors

310 and 320 are alternately spaced between the two L-shaped formworks 200, and the first and

second connectors

310 and 320 are alternately spaced between the L-shaped formworks 200 and the straight-type formwork 100. The width of the first connecting member 310 in the vertical direction is greater than the width of the second connecting member 320, and the upper surface of the first connecting member 310 and the upper surface of the second connecting member 320 are located on the same horizontal plane or the lower surface of the first connecting member 310 and the lower surface of the second connecting member 320 are located on the same horizontal plane. Optionally, the width of the first connector 310 in the vertical direction is 2 times the width of the second connector 320. Along the length direction of the two L-shaped shear walls, the first connecting members 310 and the second connecting members 320 are arranged in a staggered manner, so that the strength can be ensured, and meanwhile, the waste of materials is effectively avoided, so that the requirements on the uniformity and the economy of the module are met. The first connecting member 310 and the second connecting member 320 are chamfered at the sharp corners for demolding. The first connecting pieces 310 and the second connecting pieces 320 are arranged in a staggered mode, so that the middle through portion of the module is effectively reinforced, compared with the existing market module, the serpentine through mode is changed into the pull beam type direct through mode, and the stress is direct. Meanwhile, the arrangement of the first connector 310 and the second connector 320 can improve the transportation efficiency by about 15-20%.

Optionally, the upper surface of the first connecting piece 310 and the upper surface of the second connecting piece 320 are located on the same horizontal plane, a plurality of accommodating grooves 330 are disposed on both the upper surface of the first connecting piece 310 and the upper surface of the second connecting piece 320, and reinforcing steel bars are placed in the accommodating grooves 330. Optionally, protruding strips 340 protruding upwards are disposed on both the upper surface of the first connecting piece 310 and the upper surface of the second connecting piece 320 at intervals, and the receiving groove 330 for placing a reinforcing steel bar is formed between two adjacent protruding strips 340. Optionally, the surfaces of the first connecting member 310 and the second connecting member 320 have three receiving grooves 330, and one steel bar may be placed in the middle, two steel bars may be placed on two sides, and three steel bars may be placed as required. The protruding strips 340 do not weaken the cross-sections of the first and

second connectors

310 and 320, and do not form defects on the upper surfaces of the first and

second connectors

310 and 320, thereby further preventing the breakage of the connectors 300 and facilitating the operation of workers without the hands from being too deep into the modules when binding the reinforcing bars. The existence of the connecting piece 300 enables the concrete shear wall to form vertical joints, after concrete is poured, the connecting piece 300 only has EPS and does not have concrete, and as the elasticity modulus of the EPS is far greater than that of the concrete, the EPS is equivalent to a shear wall with vertical joints, namely, gaps are formed in the concrete shear wall, so that the EPS shear wall has better integrity in an elasticity range, the rigidity reduction is smaller, and the EPS shear wall has good shear bearing capacity with a common shear wall.
