When the shearing wall formwork is slid into the sealing base 1, the fastening bolt 2 can be twisted by the construction personnel to pre-tighten the shearing wall formwork, so that the shearing wall formwork and the sealing base 1 are not too loose, and the sealing base 1 installed in the first half is separated from the shearing wall formwork when the construction personnel installs the sealing base 1 and the shearing wall formwork. A ejection mechanism is arranged between the shearing wall formwork and the sealing base 1. When the sealing base 1 is installed with the shearing wall formwork through the fastening bolt 2, the construction personnel can use the ejection mechanism to reinforce the connection between the sealing base 1 and the shearing wall formwork, and the ejection mechanism can provide jacking force for the upper and lower ends of the sealing base 1, so as to provide sealing effect for the connection between the sealing base 1 and the shearing wall formwork, and avoid a large amount of concrete flowing out when the concrete is poured;

[0026] Meanwhile, each sealing base 1 is rotationally connected through a hinge 15, so that when the construction personnel connects the sealing base 1 and the shearing wall formwork, the angle of the sealing base 1 can be finely adjusted through the bending mode. Therefore, the sealing base 1 can be connected and installed with the shearing wall formwork even if the bottom of the wood board used by the shearing wall formwork is inclined to a certain extent.

[0027] It should be noted that the shearing wall formwork in the present application is made of wood.

[0028] The ejection mechanism comprises a sliding plate 11 slidingly arranged inside the sealing base 1, an ejection blade 9 fixedly arranged between the sliding plate 11 and the shear wall formwork, and a lifting block 13 for lifting the ejection blade 9 upward, the lifting block 13 is arranged on the side of the inclined surface of the lifting block 13 and is fixedly connected with a lifting rod 12, and two driving rods 3 are arranged on the outer side of the sealing base 1 and are used for slidingly driving the lifting block 13, when the construction personnel further fix the sealing base 1 and the shear wall formwork by using the ejection mechanism, first, the construction personnel drives the driving rod 3, the driving rod 3 drives the lifting block 13 to move when rotating, so that the lifting block 13 gradually moves to the bottom of the lifting rod 12, and the lifting rod 12 is gradually lifted upward by the inclined surface of the lifting block 13, so that the ejection blade 9 moves upward along with the lifting rod 12, and then the ejection blade 9 gradually inserts into the shear wall formwork;

[0029] When the ejection blade 9 is inserted into the shear wall formwork, the sealing base 1 is subjected to downward resistance, so that the bottom of the sealing base 1 is in abutment with the placing surface, so that the connection between the device and the shear wall formwork plays the sealing role mentioned above.

[0030] Further, the two driving rods 3 are rotatably connected with the outer side of the sealing base 1 through the rotating shaft 6, the lower half of the driving rod 3 is fixedly provided with a connecting rod 4, the end of the connecting rod 4 away from the driving rod 3 is slidingly connected with the lifting block 13, the outer side of the sealing base 1 is provided with two arc-shaped sliding grooves 5 for slidingly accommodating the connecting rod 4, and the lifting block 13 is also provided with a vertical sliding groove 14 for vertically slidingly accommodating the connecting rod 4, and the driving rod 3 is rotatably connected with the sealing base 1 through the rotating shaft 6, so that the construction personnel can drive the driving rod 3, so as to drive the lifting block 13 to move by using the driving rod 3;

[0031] It should be noted that the arc-shaped sliding groove 5 and the vertical sliding groove 14 arranged on the sealing base 1 and the lifting block 13 respectively can make the connecting rod 4 slide on the sealing base 1 and the lifting block 13 respectively;

[0032] The vertical sliding groove 14 moves in a fan shape on the sealing base 1 and moves vertically in a small amplitude on the lifting block 13, so that when the connecting rod 4 moves in a fan shape, the lifting block 13 is pulled to move in the moving direction, so that the driving rod 3 can drive the lifting block 13 to move through the connecting rod 4, and the lifting block 13 can lift the lifting rod 12 upward through the inclined surface.

[0034] When it is necessary to adjust the sealing base 1 and the shear wall formwork, the construction personnel first pull the pull rod 8, so that the pull rod 8 can drive the ejection blade 9 to move downward together, so that the ejection blade 9 gradually moves away from the bottom of the shear wall formwork, then the construction personnel loosen the two fastening bolts 2, so that the sealing base 1 can be connected to the shear wall formwork, and thus the sealing base 1 can be directly adjusted.
