Description

Technical Field

[0001] This invention relates to the field of building wall technology, and in particular to a prefabricated sandwich insulated wall and its connectors. Background Technology

[0002] Concrete sandwich composite wall panels have obvious advantages, but the thermal bridging effect of the connectors in concrete sandwich composite wall panels still restricts the thermal insulation performance of the building envelope, and a large amount of heat is lost from the wall panels at the connectors of the building envelope.

[0003] While threaded metal rod connectors can meet the bonding strength requirements of inner and outer leaf walls, the high thermal conductivity of metal creates thermal bridges within the wall, increasing heat loss and affecting the insulation performance of the enclosure structure. Furthermore, while connectors are typically used to fix insulation layers, multiple insulation layers cannot be assembled together, leading to high repair costs when insulation layers are damaged. Therefore, this paper proposes an assembled sandwich insulation wall and its connectors. Summary of the Invention

The structural wall and the protective layer are uniformly attached to the outer walls of the several insulation layers on adjacent sides. Two irregularly shaped slots are respectively opened on adjacent sides of the rear surface of each insulation layer. Limiting grooves are uniformly opened on the inner walls of the irregularly shaped slots. Two support blocks are respectively installed on the other adjacent side of the rear surface of each insulation layer. Square blocks are uniformly installed on the side of each support block away from the insulation layer. Limiting protrusions are symmetrically installed on the outer walls of the square blocks.

The outer walls of the square blocks 9 and support blocks 8 on one insulation layer 103 are attached to the inner wall of the irregular groove 3 on another insulation layer 103. The outer wall of the upper limit protrusion 10 of one insulation layer 103 is attached to the inner wall of the upper limit groove 11 of another insulation layer 103.

[0036] In one embodiment, two placement plates 5 are respectively installed on the opposite side of the rear surface of the insulation layer 103. The lower surface of the placement plate 5 is respectively installed on the upper surface of the support block 8 and the square card block 9.

The outer wall of the placement plate 5 on one insulation layer 103 is attached to the inner wall of the placement groove 4 on the other insulation layer 103. By setting the placement plate 5 and the placement groove 4, the sealing performance of the assembly of multiple insulation layers 103 can be improved, and the strength of the assembly of multiple insulation layers 103 can be enhanced.

[0037] In one embodiment, an arc-shaped portion 27 is provided on the inner top wall of the limiting groove 11. The arc-shaped portion 27 is provided to facilitate the movement of the limiting protrusion 10 into the limiting groove 11.

[0038] The connector 2 of the prefabricated sandwich insulated wall includes a hexagonal post 201, a connecting rod 202, and a threaded rod 203. A hexagonal through hole 6 is formed on the front surface of the insulation layer 103. A second hexagonal groove 13 and a third hexagonal groove 22 are evenly formed on the adjacent side of the structural wall 101 and the protective layer 102, respectively. A first hexagonal groove 12 and a fourth hexagonal groove 24 are evenly formed on the opposing side of the structural wall 101 and the protective layer 102, respectively. A fourth through hole 23 is formed on the inner wall of the third hexagonal groove 22, and the fourth through hole 23 and the fourth hexagonal groove 24 are connected. A first through hole 14 is formed on the inner wall of the second hexagonal groove 13, and the first hexagonal groove 12 and the first through hole 14 are connected. A third through hole 6 is formed on one side of the hexagonal post 201. The outer walls of the hole 20 and the hexagonal column 201 are respectively attached to the inner walls of the second hexagonal groove 13 and the third hexagonal groove 22. The outer walls of the connecting rod 202 are respectively attached to the inner walls of the fourth through hole 23 and the third through hole 20. A second hexagonal stop block 25 is installed at one end of the connecting rod 202. The outer wall of the second hexagonal stop block 25 is attached to the inner wall of the fourth hexagonal groove 24. A hexagonal plate 18 is provided inside the first hexagonal groove 12. One side of the hexagonal plate 18 is installed at one end of the threaded rod 203. A threaded cavity 21 is opened at the other end of the connecting rod 202.

A first hexagonal heat insulation block 19 and a second hexagonal heat insulation block 26 are respectively installed on the inner walls of the first hexagonal groove 12 and the fourth hexagonal groove 24.

[0039] In one embodiment, a hexagonal locking block 7 is installed on the outer wall of the hexagonal column 201. The outer wall of the hexagonal locking block 7 is attached to the inner wall of the hexagonal through hole 6. By setting the hexagonal locking block 7, the position of the insulation layer 103 can be easily locked, and the position of the hexagonal column 201 can be limited.

[0040] In one embodiment, the inner wall of the first hexagonal groove 12 is fitted with a first hexagonal stop 15, and a second through hole 16 is provided on one side of the first hexagonal stop 15.

[0042] In operation, this invention involves the following steps: Multiple insulation layers 103 are sequentially connected via a support block 8, a square locking block 9, and a shaped slot 3. The square locking block 9 engages with the limiting protrusion 10 within the limiting groove 11. The assembled insulation layer 103 is then positioned between the structural wall 101 and the protective layer 102. The hexagonal post 201, along with the hexagonal locking block 7, is moved into the hexagonal through-hole 6 on the insulation layer 103. The hexagonal post 201 then moves into the second hexagonal groove 13 and the third hexagonal groove 22, respectively, where it is locked. The second hexagonal stop block 25 is moved into the fourth hexagonal groove 24. The second hexagonal stop block 25 then drives the connecting rod 202 sequentially through the fourth... Inside the through hole 23 and the third through hole 20, the first hexagonal stop block 15 is placed inside the second through hole 16, and a washer 17 is installed outside the threaded rod 203. At this time, the hexagonal plate 18 drives the threaded rod 203 to rotate through the second through hole 16 in the threaded cavity 21. Personnel use a sleeve to drive the hexagonal plate 18 and the threaded rod 203 to rotate in the threaded cavity 21, which is used to facilitate the reinforcement and fixation between the structural wall 101, the protective layer 102 and the insulation layer 103. At this time, it is only necessary to move the first hexagonal insulation block 19 and the second hexagonal insulation block 26 into the first hexagonal groove 12 and the fourth hexagonal groove 24 respectively, and then seal them with cement again.

Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and these should all be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
