[0025] An elastic cavity 8 is provided inside the thermal insulation core material 7 .
[0026] The corrugated steel plate 4 has a V-shaped structure.
[0027] This application fixes a foldable and stretchable corrugated steel plate in the deformation joint between two buildings. The foldable and stretchable corrugated steel plate can well adapt to the expansion and contraction of the deformation joint. A hollow insulation core material is set on the outside of the corrugated steel plate. The hollow insulation core material can not only well adapt to compression and extension, but also play a certain role in heat preservation of the building. One or more layers of waterproof layer are applied to the outside of the insulation core material. A leveling mortar layer is set on the outside of the waterproof layer to fill the outside of the deformation joint. Finally, an anti-cracking mortar layer is set on the outside of the leveling mortar layer and is integrated with the exterior walls of the two buildings. This not only beautifies the appearance, but also resists cracking and is waterproof. The specific structure and description of this application are as follows:
[0028] The first building body 1 and the second building body 2 generally refer to building units. A deformation joint 3 is provided between the first building body 1 and the second building body 2. The deformation joint 3 is mainly used to adapt to the deformation due to thermal expansion and contraction between the two adjacent buildings and prevent the two buildings from being squeezed against each other.
[0029] In order to make the overall appearance of the building more beautiful, prevent rainwater from entering the expansion joint, and at the same time have an insulation effect on the wall, step surfaces 13 are respectively opened on both sides of the deformation joint 3 and located on the outer side surface of the first building body 1 and the outer side surface of the second building body 2. A corrugated steel plate 4 is arranged in the deformation joint 3, and both sides of the corrugated steel plate 4 are fixed to the step surface 13 on the corresponding side by countersunk steel plate anchor bolts 5. At the same time, in order to prevent rainwater from invading the deformation joint 3 through the gap between the contact surface of the corrugated steel plate 4 and the step surface 13, a layer of sealing strip 6 is laid on the contact surface of the corrugated steel plate 4 and the step surface 13, so that the sealing strip 6 is clamped between the corrugated steel plate 4 and the step surface 13 to play a waterproof role. The step surface 13 is provided to facilitate the subsequent integration and leveling of the deformation joint 3 with the outer walls of the first building body 1 and the second building body 2, and on the other hand, it is convenient for fixing the corrugated steel plate 4, so that the corrugated steel plate 4 can be fixed on the step surface 13, and the countersunk steel plate anchor bolt 5 can be driven into from the front of the building without obstruction. At the same time, the corrugated steel plate 4 will not protrude from the outer wall surface of the building body, and the aesthetics is good.
[0030] The corrugated steel plate 4 is a V-shaped structure that can be folded and stretched, so that the corrugated steel plate 4 can adapt to a certain degree of deformation of the expansion joint. At the same time, the corrugated steel plate 4 can provide a certain inner support for the insulation and waterproof structure set on the outside of the corrugated steel plate 4.
[0031] An insulating core material 7 is fixed on the outside of the corrugated steel plate 4 and inside the deformation joint 3. In order to allow the insulating core material 7 to better adapt to deformation, the insulating core material 7 is designed to have an internal hollow structure, and an elastic cavity 8 is provided inside the insulating core material 7. In this way, the compression and ductility of the insulating core material 7 will be better, and it will better adapt to the deformation of the deformation joint 3.
[0032] A steel mesh concrete base layer 9 is fixed outside the insulation core 7 and within the expansion joint 3. Laying steel mesh in concrete effectively prevents concrete cracking and deformation. One or more layers of waterproof layer 10 are applied to the outer surface of the steel mesh concrete base layer 9, effectively preventing rainwater from intruding into the expansion joint 3.
[0033] A leveling mortar layer 11 is provided on the outside of the waterproof layer 10. This layer is used to fill the expansion joint 3 and the stepped surface 13, ensuring that the mortar layer outside the expansion joint 3 and the stepped surface 13 is flush with the mortar layer on the exterior walls of the first and second building bodies 1 and 2. An anti-cracking mortar layer 12 is provided on the outside of the leveling mortar layer 11. This anti-cracking mortar layer 12 is integrated with the anti-cracking mortar layers on the exterior walls of the first and second building bodies 1 and 2, enhancing the appearance of the buildings.

It cannot be considered that the specific implementation of the present application is limited to these descriptions. For ordinary technicians in the technical field to which the present application belongs, the present application will also have various simple replacements, improvements and changes without departing from the concept of the present application. Various simple replacements, improvements and changes made should be deemed to fall within the scope of protection of the present application.
