Description

Technical Field

[0001] This application relates to the technical field of building materials, and in particular to a composite wall. Background Technology

[0002] Currently, building walls are generally made of brick or lightweight cement board. Their disadvantages include numerous construction procedures, long construction periods, significant susceptibility to climate, and high maintenance costs. Therefore, in order to protect land resources and the environment and reduce construction costs, various composite building materials are gradually being promoted and used, especially composite wall materials that integrate wall insulation, which have attracted increasing attention.

[0003] In existing technologies, composite walls are assembled sequentially from multiple prefabricated templates, with insulation boards installed inside each template. The sequential assembly of multiple prefabricated templates forms a composite wall that integrates wall insulation, greatly improving the construction period. However, this type of composite wall has poor environmental adaptability. In hot summers, the heat inside the room dissipates slowly through the composite wall, causing the room to remain in a high-temperature state for a long time, which inconveniences people's normal lives. Therefore, further improvements are needed. Summary of the Invention

[0004] To improve the environmental adaptability of composite walls, this application provides a composite wall.

[0005] The composite wall provided in this application adopts the following technical solution:

[0006] A composite wall includes a base and multiple prefabricated templates disposed on top of the base. Each prefabricated template has an insulation cavity, which includes a first insulation zone and a second insulation zone that are interconnected. A first insulation board is disposed in the first insulation zone, and a second insulation board is slidably installed in the second insulation zone. One side of the second insulation board extends into the first insulation zone and is in contact with the first insulation board. The prefabricated template is provided with a driving component for moving the first insulation board to the first insulation zone.

[0007] By adopting the above technical solution, the first and second insulation boards are respectively placed in the first and second insulation zones of the insulation cavity, thereby improving the insulation effect of the precast template and reducing the rate of heat loss from the composite wall. In summer, when the indoor temperature is relatively high due to prolonged exposure to sunlight, the second insulation board can be moved to the first insulation zone by the drive component. After the second insulation board is removed, the insulation effect of the second insulation zone decreases, and the indoor heat is more easily dissipated outward through the second insulation zone, thereby increasing the rate of heat dissipation and improving the environmental adaptability of the composite wall.

[0008] Optionally, a connecting rod is provided between two vertically adjacent prefabricated templates, and the two ends of the connecting rod abut against two vertically adjacent second insulation boards respectively. The two vertically adjacent second insulation boards abut against each other through the connecting rod. The base is provided with an installation cavity. The driving assembly includes a lifting plate, a lifting rod, and a driving component. The lifting plate is slidably installed in the installation cavity. One end of the lifting rod is connected to the lifting plate, and the other end extends out of the base and abuts against the second insulation board of the adjacent prefabricated template. The prefabricated template has a through slot for the connecting rod or the lifting rod to pass through. The driving component is provided on the lifting plate to drive the lifting plate to rise and fall.

[0009] By adopting the above technical solution, through the setting of lifting plate, lifting rod and driving component, the driving component drives the lifting plate to rise, and the lifting plate drives the lifting rod to move upward, thereby pushing the second insulation board of the adjacent prefabricated template upward. The two vertically adjacent insulation boards are connected to each other by the connecting rod, so that the lifting plate can drive multiple second insulation boards in a vertical row to move synchronously, forcing the second insulation boards to move into the first insulation zone, so that the heat in the room can be easily dissipated outward through the multiple vertical second insulation zones, improving the heat dissipation effect of the overall structure; on the other hand, the connecting rod is inserted through the two vertically adjacent prefabricated templates, and the connecting rod can serve as the skeleton of the composite wall, improving the stability of the overall structure.

[0010] Optionally, the driving component includes a driving rod and a connecting rod. The driving rod is rotatably mounted in the mounting cavity and is provided with a moving block. The moving block is sleeved on the driving rod and threadedly connected to the driving rod. One end of the connecting rod is hinged to the moving block, and the other end is hinged to the lifting plate. One end of the driving rod extends out of the base and is detachably connected to a driving handwheel.

[0011] By adopting the above technical solution, and through the setting of the drive rod and connecting rod, when the second insulation board is moved, the drive rod is driven to rotate by the drive handwheel, so as to drive the moving block to slide along the length direction of the drive rod. The moving block forces the lifting plate to rise through the connecting rod, thereby pushing the second insulation board to the first insulation zone, improving the convenience of moving the second insulation board.

[0012] Optionally, a sliding frame is slidably installed in the second insulation zone, and the second insulation board is disposed in the sliding frame. The second insulation board is slidably installed in the second insulation zone through the sliding frame. The bottom wall and the top wall of the sliding frame are provided with mating grooves. The mating grooves are used for mating rods or lifting rods to be inserted. The second insulation board and the mating rod or the second insulation board and the lifting rod are abutted by the sliding frame.

[0013] By adopting the above technical solution, the sliding frame provides an installation carrier for the second insulation board, allowing the second insulation board to slide and install in the second insulation area. The docking groove is used for the matching insertion of docking rods or lifting rods, so that the docking rod and the sliding frame, or the lifting rod and the sliding frame, can be connected to limit the docking rod or the lifting rod. The docking rod can serve as a skeleton between two vertically adjacent prefabricated templates, improving the stability of the overall structure.

[0014] Optionally, the precast template has a sealing groove on its surface, with both ends of the sealing groove extending along the height direction. A connecting strip is installed between two horizontally adjacent precast templates, and the connecting strip is embedded between the sealing grooves of the two horizontally adjacent precast templates. The side wall of the connecting strip is provided with a sealing strip. A locking component is provided between the connecting strip and the precast template, and the connecting strip and the precast template are connected by the locking component.

[0015] By adopting the above technical solution, the connecting strip provides an installation carrier for the sealing strip, allowing the sealing strip to be installed between the sealing grooves of two horizontally adjacent prefabricated templates, thereby improving the sealing effect of the overall structure; the connecting strip is fixed by the locking component, improving the connection stability of the sealing strip.

[0016] Optionally, an installation groove is provided at the connection between adjacent sidewalls of the precast template. The installation groove penetrates the surface of the precast template away from the sealing groove. The installation groove is an arc-shaped groove, and the installation grooves of adjacent precast templates form a complete circular groove structure. The locking assembly includes a locking rod, a locking block, and a locking element. One end of the locking rod is connected to the connecting strip, and the other end passes through the adjacent precast template and extends to the installation groove. A limiting ring groove is provided on the outer peripheral wall of the locking rod, located within the installation groove. A cutting surface communicating with the limiting ring groove is provided on the outer peripheral wall of the end of the locking rod away from the connecting strip. The locking block is disposed in the installation groove of the adjacent precast template. The locking block has a sliding groove for the end of the locking rod away from the connecting strip to be fitted through. When the locking block moves to the limiting ring groove and rotates, the locking block engages with the limiting ring groove. The locking element is disposed between the installation groove and the locking block to restrict the circumferential rotation of the locking block.

[0017] By adopting the above technical solution, through the setting of locking rod, locking block, and locking fastener, during the installation of the connecting strip, the connecting strip is embedded in the sealing groove, and one end of the locking rod passes through the installation groove. Then, the locking block is inserted into the locking rod from the side away from the connecting strip. When the locking block moves to the limiting ring groove, it is driven to rotate a certain angle around the axial direction of the locking rod, so that the locking block is engaged with the inner wall of the limiting ring groove. Through the circumferential rotation of the locking block by the locking fastener, the locking block and the locking rod are connected as a whole, so as to fix the connecting strip in the sealing groove, improving the ease of installation of the connecting strip. On the other hand, after the locking block is engaged with the limiting ring groove, the locking block abuts against the bottom wall of the installation groove, thereby limiting the adjacent precast templates, so that the adjacent precast templates are connected as a whole, greatly improving the stability of the overall structure.

[0018] Optionally, the bottom wall of the mounting groove is provided with a first locking hole, and the locking block is provided with a second locking hole. When the locking block is located at the cutting surface of the locking rod, the first locking hole and the second locking hole are misaligned. The locking device includes a locking post and a locking spring. The locking post is slidably installed in the first locking hole, and the locking spring is installed between the locking seat and the first locking hole. In its normal state, the locking spring causes the locking post to be partially exposed in the first locking hole for insertion into the second locking hole.

[0019] By adopting the above technical solution, through the setting of the locking pin and locking spring, during the process of the locking block being sleeved on the locking rod from the end away from the connecting bar (when the locking block has not moved to the limiting ring groove), the first locking hole and the second locking hole are misaligned. As the locking block continues to move towards the limiting ring groove, the side wall of the locking block near the limiting ring groove can push the locking pin and force the locking pin to move into the first locking hole. When the locking pin moves into the first locking hole, the locking block moves to the limiting ring groove. Then, the locking block is rotated so that the locking block is engaged in the limiting ring groove. By controlling the rotation angle of the locking block, the first locking hole and the second locking hole are kept relative. When the first locking hole and the second locking hole are relative, the locking pin is inserted into the second locking hole under the action of the locking spring to restrict the circumferential rotation of the locking block, which greatly improves the ease of installation between the locking block and the locking rod.

[0020] Optionally, the second locking hole is a through hole penetrating the locking block. The locking block is detachably connected to an unlocking disc, which is provided with multiple unlocking pins. The unlocking pins are used to be inserted into the second locking hole to push the locking pins out of the second locking hole.

[0021] By adopting the above technical solution and setting the unlocking disc, when it is necessary to disassemble the composite wall, the unlocking pin of the unlocking disc is inserted into the second locking hole to push the locking pin out of the second locking hole, thereby releasing the limiting effect on the locking block. Then, the unlocking disc is driven to rotate a certain angle, which allows the locking block to disengage from the limiting ring groove, improving the ease of disassembly of the locking block. This facilitates the recycling of prefabricated templates and other components in the composite wall, thereby improving the flexibility of the overall structure.

[0022] Optionally, the second locking hole is a through hole penetrating the locking block. A decorative block is provided on the side of the locking block away from the connecting strip. An elastic post for insertion into the second locking hole is fixed on the side wall of the decorative block near the locking block. When the elastic post is fully inserted into the second locking hole, the elastic post deforms, and the side wall of the decorative block away from the locking block remains flush with the surface of the precast template away from the connecting strip.

[0023] By adopting the above technical solution, after the installation of the locking block is completed, the elastic column of the decorative block is aligned with the second locking hole of the locking block, and then a certain pushing force is applied to deform the elastic column and embed it into the second locking hole. The side wall of the decorative block away from the locking block is flush with the surface of the precast template away from the connecting strip, thereby improving the flatness of the composite wall surface and thus improving the aesthetics of the overall structure.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. By setting up the first and second insulation boards, the first and second insulation boards with insulation effects are respectively set in the first and second insulation areas of the insulation cavity, thereby improving the insulation effect of the precast template and reducing the rate of heat loss from the composite wall. In summer, when the indoor temperature is relatively high due to prolonged exposure to sunlight, the second insulation board can be moved to the first insulation area by the drive component. After the second insulation board is removed, the insulation effect of the second insulation area decreases, and the indoor heat is more easily dissipated to the outside through the second insulation area, thereby increasing the rate of heat dissipation from the inside and improving the environmental adaptability of the composite wall.

[0026] 2. By setting up connecting rods, which pass through two vertically adjacent precast templates, the connecting rods can serve as the skeleton of the composite wall, improving the overall structural stability;

[0027] 3. By using locking rods, locking blocks, and locking fasteners, during the installation of the connecting strip, the connecting strip is embedded in the sealing groove, and one end of the locking rod passes through the installation groove. Then, the locking block is inserted into the locking rod from the side away from the connecting strip. When the locking block moves to the limiting ring groove, it is driven to rotate a certain angle around the axial direction of the locking rod, so that the locking block is engaged with the inner wall of the limiting ring groove. Through the circumferential rotation of the locking block by the locking fasteners, the locking block and the locking rod are connected as a whole, thus fixing the connecting strip in the sealing groove and improving the ease of installation of the connecting strip. On the other hand, after the locking block is engaged with the limiting ring groove, the locking block abuts against the bottom wall of the installation groove, thereby limiting the adjacent precast templates and connecting the adjacent precast templates as a whole, greatly improving the stability of the overall structure.

[0037] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0038] This application discloses a composite wall.

[0039] Reference Figure 1 A composite wall includes a base 1 and a prefabricated template 2. In this embodiment, the base 1 is a long strip structure and is used to be installed on the ground or floor surface. It should be noted that when the base 1 is set on the ground, multiple anchor rods (not shown in the figure) can be set on the bottom wall of the base 1. The base 1 is fixed to the ground by inserting the anchor rods. When the base 1 is set on the floor surface, the base 1 can be installed on the floor surface by bolt connection.

[0040] Reference Figure 1 , Figure 2 , Figure 3Multiple precast templates 2 are provided, and all precast templates 2 are set on the top of the base 1. Multiple precast templates 2 are stacked sequentially along the height direction. The base 1 and multiple precast templates 2 are combined to form a composite wall. The precast template 2 includes a first precast slab 27 and a second precast slab 28. The slab surfaces of the first precast slab 27 and the second precast slab 28 are attached to each other. The top walls of the first precast slab 27 and the top walls of the second precast slab 28 are fixedly installed with insertion strips 271. The bottom walls of the first precast slab 27 and the bottom walls of the second precast slab 28 are provided with insertion grooves 272. The insertion grooves 272 are used for the insertion strips 271 to be matched and inserted. Two vertically adjacent precast templates 2 are connected and engaged with each other through the insertion strips 271 and the insertion grooves 272.

[0041] Reference Figure 2 , Figure 3 A connector 29 is installed between the first precast slab 27 and the second precast slab 28. The first precast slab 27 and the second precast slab 28 are detachably connected by the connector 29. In this embodiment, the connector 29 includes a connecting bolt 291 and a connecting nut 292. The connecting bolt 291 passes through the insertion strip 271 of the first precast slab 27 and the insertion strip 271 of the second precast slab 28 in sequence. The connecting nut 292 is sleeved on the connecting bolt 291 and threadedly connected to the connecting bolt 291. The first precast slab 27 and the second precast slab 28 are combined by the connecting bolt 291 to form the precast template 2.

[0042] It should be noted that the connecting bolt 291 in this embodiment is a countersunk bolt. The inner wall of the insertion groove 272 of the first precast plate 27 and the inner wall of the insertion groove 272 of the second precast plate 28 are provided with a relief groove 273 to avoid the connecting bolt 291. With this design, the first precast plate 27 and the second precast plate 28 are connected into a whole by the connecting bolt 291. When the insertion strip 271 is inserted into the insertion groove 272 in the upper precast template 2, the insertion groove 272 can limit the connecting bolt 291, reducing the possibility of the connecting bolt 291 and the connecting nut 292 separating.

[0043] Reference Figure 2 , Figure 4 A sealing groove 25 is provided on the surface of the precast template 2 (i.e. the surface of the first precast slab 27 away from the second precast slab 28). The two ends of the sealing groove 25 extend along the height direction. Each precast template 2 has two sealing grooves 25. The two sealing grooves 25 are symmetrically distributed on both sides of the surface of the first precast slab 27. The sealing grooves 25 of two horizontally adjacent precast templates 2 are interconnected. A connecting strip 5 is installed between two horizontally adjacent precast templates 2. The connecting strip 5 is embedded between the sealing grooves 25 of two horizontally adjacent precast templates 2. The two ends of the connecting strip 5 extend along the height direction and are embedded in the sealing grooves 25 of all vertical precast templates 2.

[0044] Reference Figure 1 , Figure 4 It should be noted that the lower end of the connecting strip 5 extends to the base 1 and is fixedly connected to the surface of the base 1 by bolts; a sealing strip 51 is fixed to the side wall of the connecting strip 5 near the second precast plate 28. The two ends of the sealing strip 51 extend along the length of the connecting strip 5. The sealing strip 51 is a rubber strip, which is used to improve the sealing between two horizontally adjacent precast templates 2.

[0045] Reference Figure 2 , Figure 4 , Figure 5 An installation groove 26 is provided at the connection between adjacent side walls of the second precast slab 28. There are four installation grooves 26, which are distributed at the four top corners of the second precast slab 28. The installation grooves 26 penetrate the surface of the second precast slab 28 away from the first precast slab 27. In this embodiment, the installation groove 26 is an arc-shaped groove, and the installation grooves 26 of the four adjacent second precast slabs 28 form a complete circular groove structure. A locking component 6 is provided between the connecting strip 5 and the precast template 2, and the connecting strip 5 and the precast template 2 are connected by the locking component 6.

[0046] Reference Figure 4 , Figure 5 , Figure 6 The locking assembly 6 includes a locking rod 61, a locking block 62, and a locking element. The locking rod 61 has a circular rod-shaped structure. One end of the locking rod 61 is fixedly connected to the side wall of the connecting strip 5 near the second precast plate 28. The locking rod 61 and the connecting strip 5 are fixedly connected by welding. The other end of the locking rod 61 passes through four adjacent first precast plates 27 and four adjacent second precast plates 28 in sequence and extends to the mounting groove 26. A limiting ring groove 611 is formed on the outer peripheral wall of the locking rod 61. The limiting ring groove 611 is arranged in a ring around the axial direction of the locking rod 61 and is located in the mounting groove 26. A cutting surface 612 is formed on the outer peripheral wall of the end of the locking rod 61 away from the connecting strip 5. There are two cutting surfaces 612. The two cutting surfaces 612 are symmetrically distributed around the axial direction of the locking rod 61. The cutting surfaces 612 are connected to the limiting ring groove 611, and the distance between the two cutting surfaces 612 is equal to the outer diameter of the limiting ring groove 611.

[0047] Reference Figure 4 , Figure 5 , Figure 6For ease of description, the portion of the locking rod 61 with the cutting surface 612 (i.e., the portion of the locking rod 61 with the cutting surface 612) is defined as the locking part 613. In this embodiment, the locking block 62 is configured as a circular block structure. The locking block 62 has a sliding groove 621 that penetrates through the locking block 62. The shape of the sliding groove 621 is adapted to the cross-sectional shape of the locking part 613. The locking block 62 slides and is fitted onto the locking part 613 through the sliding groove 621. When the locking block 62 is fitted onto the locking part 613 and moves to abut against the bottom wall of the mounting groove 26, the locking block 62 moves into the limiting ring groove 611. When the locking block 62 is rotated to make the locking block 62 and the cutting surface 612 misaligned, the locking block 62 is engaged with the inner wall of the limiting ring groove 611.

[0048] Reference Figure 4 , Figure 5 Each mounting groove 26 has a first locking hole 261 on its bottom wall, and the locking block 62 has a plurality of second locking holes 622. In this embodiment, the number of second locking holes 622 is set to four. The four second locking holes 622 are corresponding to the first locking holes 261 in the mounting grooves 26 of the four adjacent second precast plates 28. When the locking block 62 is fitted onto the locking part 613 through the sliding groove 621, the first locking holes 261 and the second locking holes 622 are misaligned. When the locking block 62 moves into the limiting ring groove 611 and is driven to rotate a certain angle, the second locking holes 622 can rotate to a state opposite to the first locking holes 261. In this embodiment, when the rotation angle of the locking block 62 is 45 degrees, the second locking holes 622 rotate to a state opposite to the first locking holes 261.

[0049] Reference Figure 4 , Figure 5The locking device is installed between the mounting slot 26 and the locking block 62 to restrict the circumferential rotation of the locking block 62. Multiple locking devices are provided, corresponding to multiple first locking holes 261. Each locking device includes a locking post 63 and a locking spring 64. The locking post 63 is slidably installed in the first locking hole 261, and the locking spring 64 is installed within the first locking hole 261. One end of the locking spring 64 is fixedly connected to the first locking hole 261, and the other end is fixedly connected to the locking post 63. Normally, the locking spring 64 causes one end of the locking post 63 to be partially exposed in the first locking hole 261 for insertion into a second locking hole. 622; With this design, when installing the locking block 62, the locking block 62 is fitted onto the locking part 613 and pushed to the limiting ring groove 611. Then, the locking block 62 is driven to rotate a certain angle, so that the second locking hole 622 rotates to be opposite to the first locking hole 261. The locking pin 63 is inserted into the second locking hole 622 under the action of the locking spring 64 to restrict the circumferential rotation of the locking block 62, so that the locking block 62 is kept locked in the limiting ring groove 611, thereby connecting the locking block 62 and the connecting strip 5 into a whole, and further connecting the connecting strip 5 and all the prefabricated templates 2 into a whole.

[0050] Reference Figure 7 In this embodiment, the second locking hole 622 does not penetrate the through hole of the locking block 62. The locking block 62 is detachably connected to the unlocking disc 7, which is circular in shape. Multiple unlocking posts 71 are fixedly installed on the side wall of the unlocking disc 7. All unlocking posts 71 are correspondingly arranged with all the second locking holes 622 of the locking block 62. The length of the unlocking post 71 is adapted to the thickness of the locking block 62. The unlocking post 71 is used to insert into the second locking hole 622 to push the locking post 63 out of the second locking hole 622. This design allows the locking block 62 to be detachably installed on the locking rod 61, so that when the composite wall needs to be disassembled, the locking block 62 can be disassembled, improving the ease of disassembly and assembly of the overall structure.

[0051] Reference Figure 4 , Figure 5 A decorative block 8 is installed on the side of the locking block 62 away from the connecting strip 5. Multiple elastic posts 81 are fixedly installed on the side wall of the decorative block 8 near the locking block 62. The multiple elastic posts 81 are correspondingly arranged with multiple second locking holes 622. The elastic posts 81 are elastically arranged and are used to be inserted into the corresponding second locking holes 622. When the elastic posts 81 are fully inserted into the second locking holes 622, the elastic posts 81 deform, and the side wall of the decorative block 8 away from the locking block 62 remains flush with the surface of the precast template 2 away from the connecting strip 5. The decorative block 8 can be detachably installed on the locking block 62 through the elastic posts 81.

[0052] Reference Figure 1A sealing strip 9 is installed on the top of the base 1. All precast templates 2 are located between the base 1 and the sealing strip 9. The two ends of the sealing strip 9 extend along the length of the base 1. The bottom wall of the sealing strip 9 has multiple sealing grooves (not shown in the figure). The multiple sealing grooves are used for the insertion of the connector strip 271 of the precast template 2. In this embodiment, the upper end of the connecting strip 5 is detachably connected to the sealing strip 9. The connecting strip 5 is detachably connected to the sealing strip 9 by bolts. Multiple first sealing blocks 91 are fixedly installed on the bottom wall of the sealing strip 9. All first sealing blocks 91 are spaced apart along the length of the sealing strip 9. Multiple second sealing blocks 12 are fixedly installed on the top wall of the base 1. All second sealing blocks 12 are spaced apart along the length of the base 1. The first sealing blocks 91 and the second sealing blocks 12 are both used to embed into the installation groove 26 of the precast template 2 to ensure the flatness of the surface of the composite wall.

[0053] Reference Figure 3 The first precast slab 27 has grooves on its surface near the second precast slab 28, and the second precast slab 28 has grooves on its surface near the first precast slab 27. The grooves of the first precast slab 27 and the second precast slab 28 are combined to form an insulation cavity 21. The insulation cavity 21 includes a first insulation area 211 and a second insulation area 212. The first insulation area 211 is located above the second insulation area 212, and the first insulation area 211 and the second insulation area 212 are interconnected.

[0054] Reference Figure 3 A fixed frame 215 is fixedly installed in the first insulation zone 211. The fixed frame 215 is located in the sink of the second precast slab 28. A first insulation board 22 is fixedly installed in the fixed frame 215 and is fixedly installed in the first insulation zone 211 through the fixed frame 215. A slide rail 216 is fixedly installed on the inner wall of the second insulation zone 212. The two ends of the slide rail 216 extend along the height direction, and the upper end of the slide rail 216 extends to the first insulation zone 211. A sliding frame 213 is provided in the second insulation zone 212. The sliding frame 213 is slidably installed on the slide rail 216, and the sliding frame 213 normally moves to the second insulation zone 212 under its own gravity. A second insulation board 23 is fixedly installed in the sliding frame 213. The second insulation board 23 is slidably installed in the second insulation zone 212 through the sliding frame 213 and can move towards the first insulation zone 211 (i.e., move upward) through the slide rail 216.

[0055] In this embodiment, the top wall of the second insulation zone 212 extends to the first insulation zone 211 and abuts against the first insulation board 22; both the first insulation board 22 and the second insulation board 23 are polyurethane insulation boards; with this design, the second insulation board 23 is normally located in the second insulation zone 212, so that the first insulation board 22 and the second insulation board 23 are normally staggered along the height direction to fill the insulation cavity 21 and improve the insulation effect of the prefabricated template 2.

[0056] Reference Figure 3 In this embodiment, the bottom wall and top wall of the sliding frame 213 in each prefabricated template 2 are provided with a docking groove 214. A docking rod 4 is installed between two vertically adjacent prefabricated templates 2. The two ends of the docking rod 4 are respectively inserted into the insulation cavity 21 of the two vertically adjacent prefabricated templates 2 and matched and inserted into the docking groove 214 of the sliding frame 213. The two vertically adjacent second insulation boards 23 are connected to each other by the docking rod 4 and the sliding frame 213 to form a whole in series. The prefabricated template 2 is provided with a driving component 3 for driving the first insulation board 22 to move to the first insulation area 211.

[0057] Reference Figure 3 , Figure 8 The base 1 has an installation cavity 11. The side wall of the base 1 is equipped with a cover plate 13 for opening and closing the installation cavity 11. The cover plate 13 can be detachably installed on the base 1 by bolt fixing. The drive assembly 3 includes a lifting plate 31, a lifting rod 32 and a drive component. A guide rod 14 is fixedly installed in the installation cavity 11. The axial direction of the guide rod 14 is vertical. The lifting plate 31 is slidably installed in the installation cavity 11. The guide rod 14 passes through the lifting plate 31. The lifting plate 31 is slidably installed in the installation cavity 11 through the guide rod 14 so that it can be raised and lowered. One end of the lifting rod 32 is fixedly connected to the top wall of the lifting plate 31. The other end passes through the base 1 and matches the docking groove 214 of the sliding frame 213 in the adjacent precast template 2. The precast template 2 (i.e. the first precast plate 27) has a through groove 24 for the docking rod 4 or the lifting rod 32 to pass through.

[0058] Reference Figure 1 , Figure 8 A driving component is installed on the lifting plate 31 to drive the lifting plate 31 to rise and fall. The driving component includes a driving rod 33 and a connecting rod 34. The driving rod 33 is rotatably installed in the mounting cavity 11. The axial direction of the driving rod 33 is perpendicular to the length direction of the lifting rod 32. One end of the driving rod 33 protrudes through the side wall of the base 1 and is detachably mounted with a driving handwheel 35. The driving handwheel 35 has a driving sleeve 351, which is sleeved on one end of the driving rod 33 and circumferentially linked with the driving rod 33 (that is, when the driving sleeve 351 rotates, it can drive the driving rod 33 to rotate). The driving rod 33 is equipped with a moving block 331, which is sleeved on the driving rod 33 and threadedly connected to the driving rod 33. One end of the connecting rod 34 is hinged to the moving block 331, and the other end is hinged to the bottom wall of the lifting plate 31.

[0059] It should be noted that, in other embodiments, ventilation holes communicating with the second insulation zone 212 can be opened on the surface of the first precast plate 27 and the surface of the second precast plate 28, so that when the second insulation plate 23 moves to the first insulation zone 211, the ventilation holes can further improve the heat dissipation effect of the second insulation zone 212.

[0060] The implementation principle of a composite wall in this application embodiment is as follows: During the installation of the composite wall, multiple prefabricated templates 2 are stacked sequentially on the top of the base 1 through the cooperation of the interlocking strips 271 and the interlocking holes. For each layer of prefabricated templates 2 stacked, a connecting rod 4 needs to be inserted into the prefabricated template 2 so that after two vertically adjacent prefabricated templates 2 are stacked, the connecting rod 4 can pass between the two vertically adjacent prefabricated templates 2. Then, a connecting strip 5 is installed on one side of the first prefabricated plate 27 so that the locking rod 61 passes into the installation groove 26 and is locked by the locking block 62, so that the base 1 and all the prefabricated templates 2 are connected as a whole to form a composite wall.

[0061] When the composite wall is used in construction sites or other places with a short service life, the locking block 62 can be disassembled by unlocking the plate 7 to facilitate the separation of multiple prefabricated templates 2, which greatly improves the ease of disassembly and assembly of the overall structure; the disassembled prefabricated templates 2, base 1, etc. can be transferred to other places for reuse, which greatly improves the flexibility of the overall structure.

[0062] Under normal conditions, the first insulation board 22 and the second insulation board 23 are used to improve the insulation effect of the precast template 2. When it is hot in summer and the indoor heat needs to be dissipated in time, the drive rod 33 is rotated and the lifting rod 32 can simultaneously lift multiple second insulation boards 23 upwards, so that the second insulation boards 23 are moved into the first insulation zone 211. After the second insulation boards 23 are lost, the insulation effect of the second insulation zone 212 is reduced, and the indoor heat is easily dissipated to the outside through the second insulation zone 212, thereby increasing the speed of indoor heat dissipation and thus improving the environmental adaptability of the composite wall.

[0063] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
