In the process of transporting the double-skin wall, one end of the outer plate 21 is detachably connected with the outer leaf plate 11 through a bolt, the outer protective frame 111 is abutted against the outer plate 21, one end of the inner plate 22 is detachably connected with the inner leaf plate 13 through a bolt, the outer plate 21 is in contact with the inner plate 22 and is perpendicular to the inner plate, and the inner plate 22 and the outer plate 21 are detachably connected through a bolt. Therefore, the inner and

outer plates

22 and 21 and the inner and outer

protective frames

131 and 111 can effectively protect the ends of the inner and

outer sheets

13 and 11 during transportation.

Referring to fig. 2 and 3, the outer sheet 11 is further provided with a communicating groove 112, the communicating groove 112 is located on one side of the outer sheet 11 close to the inner sheet 13, and the communicating groove 112 penetrates through one end of the outer sheet 11 close to the outer protective frame 111. In this embodiment, the inner protection frame 131 is formed by extending the steel reinforcement frame in the inner leaf 13, and the outer protection frame 111 is formed by extending the steel reinforcement frame in the outer leaf 11. Outer protection frame 111 and interior protection frame 131 all include the reinforcing bar of many level settings, have the interval between the adjacent reinforcing bar.

Therefore, when concrete grout enters the cavity 24, the concrete grout is less likely to leak from the joint between the inner plate 22 and the outer plate 21, and the elastic layer 42 abuts against the inner wall of the protruding cavity 211, so that the probability of the concrete grout entering the protruding cavity 211 can be reduced.

Referring to fig. 2 and 3, the protruding cavity 211 is communicated with the first threaded hole 212, the pushing mechanism comprises a first hinge plate 32 and a spring 31, the first hinge plate 32 is hinged to the outer plate 21, the hinge axis is perpendicular to the horizontal plane, one end of the first hinge plate 32 is in contact with one end of the resisting plate 4 and is connected with the resisting plate 4 through a connecting rope 33, namely, one end of the connecting rope 33 is fixedly connected with the resisting plate 4, the other end of the connecting rope is connected with one end of the first hinge plate 32, and the other end of the first hinge plate 32 extends into the first threaded hole 212. The spring 31 is positioned in the first threaded hole 212, one end of the spring is fixedly connected with the bottom of the first threaded hole 212, and the other end of the spring is abutted against the first hinge plate 32.

When the outer plate 21 and the inner plate 22 are connected, the fixing bolt 221 extends into the first threaded hole 212, and when the fixing bolt 221 abuts against one end of the first hinge plate 32 located in the first threaded hole 212, the other end of the first hinge plate 32 moves to push the abutting plate 4 out of the protruding cavity 211, so that the elastic layer 42 abuts against the inner plate 22. Thereby achieving the sealing effect. The spring 31 is now in a compressed state. When it is necessary to separate the inner and

outer plates

22 and 21, the fixing screw is removed from the first screw hole 212. At this time, the spring 31 is restored, so that the end of the first hinge plate 32 located in the first threaded hole 212 is reset, and then the end of the first hinge plate 32 moves towards the direction away from the cavity opening of the protruding cavity 211, and then the fastening plate 4 can be pulled through the connecting rope 33, so that the fastening plate 4 does not protrude out of the protruding cavity 211, and therefore a good protection effect can be achieved on the fastening plate 4.
