The exterior wall formwork 1 and the interior wall formwork 2 are arranged to form a receiving cavity 11 for receiving concrete. The exterior wall formwork 1, the interior wall formwork 2 and the pull tab 4 are all made of aluminum alloy material.

[0035] Reference Figure 1 and Figure 2 , the exterior wall formwork 1 and the interior wall formwork 2 are both made of a number of standard blocks 3. Figure 2 The standard plate includes a panel 31, an end plate 32, a transverse rib 33 and a longitudinal rib 34. The end plates 32 are fixed to both sides of the panel 31, and the end plates 32 abut against the panel 31. In this embodiment, the end plates 32 and the panel 31 are integrally formed. The panel 31 is used to contact with concrete. The end plates 32 are arranged vertically, and the end plates 32 of adjacent standard plates abut against each other. The transverse rib 33 and the longitudinal rib 34 are arranged between the oppositely arranged end plates 32, and the transverse rib 33 is arranged perpendicular to the longitudinal rib 34. The transverse rib 33 and the longitudinal rib 34 are used to improve the rigidity of the panel 31.

[0036] Reference Figure 1 and Figure 3 The standard plates are connected into a piece by pins 6 and locking plates 7. The relatively arranged standard plates are connected and fixed by pull tabs 4.

[0037] Reference Figure 3 and Figure 4 Along the length direction of the end plate 32, a plurality of grooves 321 for the pull tab 4 to pass through are provided at intervals on the side of the end plate 32 away from the panel 31; a plurality of first through holes 322 for the pin 6 to pass through are provided at intervals on the end plate 32, the pull tab 4 is provided with a second through hole 41 for the pin 6 to pass through, and a fixing hole for the locking piece 7 to pass through is provided at the end of the pin 6. Thus, the position of the standard plate and the pull tab 4 is fixed by the cooperation of the pin 6 and the locking piece 7.

[0038] The outer side of the standard plate on the same side is provided with a back rib 8 and a square buckle 9, which is plugged and fixed with the first through hole 322, and the back rib 8 is fixedly connected to the standard plate through the square buckle 9; thereby improving the structural rigidity of the aluminum alloy formwork. The back rib 8 and the square buckle 9 are prior art, and the specific structure of the square buckle 9 is not described in detail in this embodiment. One end of the diagonal brace 10 is fixedly connected to the embedded part of the floor slab, and the other end is connected to the back rib 8 through a connecting piece to improve the stability of the aluminum alloy formwork.

[0039] Reference Figure 3 The tensioning assembly 5 is arranged at the bottom of the exterior wall formwork 1 and the interior wall formwork 2. Figure 3 , Figure 5 and Figure 6The tension assembly 5 includes a tension bolt 51, a tension nut 52, a PVC conduit 53 and a rubber sleeve 54. The panel 31 is provided with a third through hole 311 for the tension bolt 51 to pass through. The tension bolt 51 is passed through the panel 31 arranged opposite to each other. The end of the tension bolt 51 is threadedly connected with the tension nut 52, and the tension nut 52 abuts against the panel 31. In this embodiment, the tension bolt 51 is arranged between two back ribs 8; and the tension nut 52 abuts against the back ribs 8 through a gasket; thereby increasing the tension effect of the tension bolt 51 on the standard plate. The tension nut 52 and the tension bolt 51 are made of steel.

[0040] When workers pour shear wall concrete into the accommodating cavity 11, the standard plate at the bottom of the aluminum alloy formwork will be subjected to a large lateral pressure, causing the bottom pull tab 4 to be subjected to a large tensile force. By adding a tension assembly 5 at the bottom of the aluminum alloy, the tension bolts 51 have a strong tensile performance, so that the tensile bolts are used to share the tensile force on the pull tab 4; thereby reducing the risk of the pull tab 4 being broken by the standard plate and reducing the risk of the aluminum alloy formwork exploding.

[0041] The PVC conduit 53 is arranged between the exterior wall formwork 1 and the interior wall formwork 2, and the PVC conduit 53 is in contact with the panel 31, and the PVC conduit 53 is sleeved on the outer periphery of the tension bolt 51. The rubber sleeve 54 is fixed on both sides of the PVC conduit 53, and the rubber sleeve 54 is provided with a connecting hole 541 for the tension bolt to pass through; the rubber sleeve 54 is in contact with the panel 31. The tension bolt 51 is separated from the concrete by the PVC conduit 53; thereby, it is convenient for the staff to remove the tension bolt 51 from the shear wall, facilitate the demoulding of the staff, and reduce the work intensity of the staff. At the same time, rubber sleeves 54 are arranged on both sides of the PVC conduit 53, so as to use the rubber sleeves 54 to block the gap that may appear between the PVC conduit 53 and the standard plate, further reducing the occurrence of slurry in the concrete entering the interior of the PVC conduit 53, so as to facilitate the staff to remove the tension bolt 51 from the PVC conduit 53.

[0042] In this embodiment, the rubber sleeve 54 includes an abutment portion 542 and an insertion portion 543, and the abutment portion 542 and the insertion portion 543 are integrally formed; the insertion portion 543 is plugged and fixed to the inner circumferential wall of the PVC conduit 53, and the abutment portion 542 abuts against the panel 31. And along the direction away from the panel 31, the distance from the outer periphery of the abutment portion 542 to the central axis decreases. The outer periphery of the abutment portion 542 of the rubber sleeve 54 is inclined, so as to utilize the lateral pressure of the concrete on the abutment portion 542 to increase the degree of extrusion between the rubber sleeve 54 and the standard plate, and further reduce the occurrence of slurry in the concrete flowing into the PVC conduit 53. The insertion portion 543 of the rubber sleeve 54 is plugged and fixed to the inner circumferential wall of the PVC conduit 53 to reduce the contact area between the rubber sleeve 54 and the concrete, thereby facilitating the staff to pull out the rubber sleeve 54. Refer to Figure 3 and Figure 4 At the same time, notches 42 are provided on both sides of the pull tab 4, and the notches 42 are provided between the exterior wall formwork 1 and the interior wall formwork 2; and the edges of the notches 42 abut against the panel 31.
