During the alignment process, the insertion rod 22 fixedly arranged on the insertion portion is inserted along the positioning groove 23, so that the accommodating portion and the insertion portion are tightly attached.

[0033] As a further provided embodiment of the utility model, the outer wall board 2 is provided with an inclined surface at both ends, and an insertion rod 22 and a positioning groove 23 are arranged at both ends respectively.

[0034] Specifically, the first end of the easily deformed arc plate 55 is fixedly connected with the waterproof plate 5, and the second end opposite to the first end is slidingly inserted into the limiting groove 31, and the adjacent surfaces of the two easily deformed arc plates 55 are provided with sawtooth grooves. The waterproof plate 5 is in a state as shown in FIG. 5 in a default state, at which time the easily deformed arc plate 55 is in an arc structure, the arc structure limits the insertion of the easily deformed arc plate 55 into the limiting groove 31, so that the waterproof plate 5 is kept arched. Figure 4 When the waterproof plate 5 is pushed by the cushion block 21, the waterproof plate 5 is bent along the gap 52 and clamps the cushion block 21. At this time, the force of the cushion block 21 on the waterproof plate 5 is directed to the center of the waterproof plate 5, thereby driving the easily deformed arc plate 55 to deflect to the center. The easily deformed arc plate 55 is bent along the sawtooth groove, and the two side walls of the sawtooth groove are tightly attached to each other, so that the easily deformed arc plate 55 is in a flat state. At this time, the easily deformed arc plate 55 can be inserted into the limiting groove 31, and the limiting groove 31 and the waterproof plate 5 are tightly connected through the easily deformed arc plate 55.

[0035] As a further provided embodiment of the utility model, the outer wall board 2 is provided with an inclined surface at both ends, and an insertion rod 22 and a positioning groove 23 are arranged at both ends respectively.

[0036] Specifically, the waterproof plate 5 is located on the heat insulation partition plate 3, and the waterproof plate 5 is slidingly inserted into the limiting groove 31 arranged on the heat insulation partition plate 3. The plastic film 51 is used to connect the waterproof plate 5 and the heat insulation partition plate 3, and the plastic film 51 is used to enclose the interior of the waterproof plate 5 to form a sealed cavity 54 for preventing water seepage, and the clamping strip 24 is in communication with the sealed cavity 54. The waterproof plate 5 is bent by the pushing of the cushion block 21, and the waterproof plate 5 is inserted into the limiting groove 31, so that the volume of the sealed cavity 54 is reduced, the gas in the sealed cavity 54 is extruded into the clamping strip 24, and the clamping strip 24 is expanded and clamps the insertion rod 22, further playing a fixing role.

[0037] As further provided by the utility model, the connecting piece 4 is assembled on the inner wall plate 1 through bolts, and the connecting piece 4 has a U-shaped piece abutting against the inner wall plate 1.

[0038] Specifically, the U-shaped piece is provided with wing-shaped parts 41 in triangular structure on two sides, and the wing-shaped parts 41 are provided with secondary through holes 43. The inner wall plate 1 is provided with a protruding part for clamping the U-shaped piece, and the connecting piece 4 is provided with a positioning through hole 42 for bolt fixation. During the bolt tightening process, the right-angle edges of the wing-shaped parts 41 gradually abut against the wall surface, and the stable characteristics of the triangular structure can ensure the connection of the two outer hanging wall plates.

[0039] Working principle: when assembling the outer hanging wall plate, the wall plate being hoisted is corresponded to the assembled wall plate, and then the insertion part in the hoisted wall plate is corresponded to the accommodating part of the assembled wall plate. During the alignment process, the insertion rod 22 fixedly arranged on the insertion part is inserted along the positioning groove 23, so that the accommodating part and the insertion part are tightly abutted.

During the abutting process of the pad 21 against the waterproof plate 5, the waterproof plate 5 is bent along the notches 52, so that the plurality of notches 52 are closed, and the waterproof plate 5 drives the pad 21 to be clamped.

[0041] At this time, the force of the pad 21 on the waterproof plate 5 is directed to the center of the waterproof plate 5, so as to drive the easily-deformable arc plate 55 to deflect to the center. The easily-deformable arc plate 55 is bent along the sawtooth groove, the two side walls of the sawtooth groove are tightly abutted against each other, so that the easily-deformable arc plate 55 is in a flat state. At this time, the easily-deformable arc plate 55 can be inserted along the limiting groove 31, the volume of the sealed cavity 54 is reduced, the gas in the sealed cavity 54 is extruded into the clamping strip 24, so that the clamping strip 24 is expanded and clamps the insertion rod 22.

[0042] The pad 21 is provided with an opening on each side. During the bending process of the waterproof plate 5, the clamping piece 53 is deflected, and the clamping piece 53 is clamped with the opening.
