[0037] In order to enhance the anchoring performance and form a stable tension and compression force, such as Figure 2 As shown, the connecting rod 42 includes a main rod 421 and a support rod 422. The main rod 421 is a hollow rod, that is, a through hole 4211 is provided along the length direction of the main rod 421, and the support rod 422 is obliquely connected to the main rod 421. The connecting rod 42 also includes a first reinforcing rod 423, a second reinforcing rod 424 and a third reinforcing rod 425. The first reinforcing rod 423 and the second reinforcing rod 424 are arranged in parallel and are both vertically connected to the main rod 421. Preferably, the main rod 421 is connected to the middle of the first reinforcing rod 423 and the second reinforcing rod 424.

[0040] In this embodiment, combined with Figure 1 and Figure 2 As shown, the first cone 4212 , the second cone 4221 and the third cone 4222 are arranged in the inner leaf plate 1 , and the first reinforcing rod 423 , the second reinforcing rod 424 and the third reinforcing rod 425 are all arranged in the prefabricated wall panel component 2 .

[0041] Preferably, the integrated kit 4 is made of hard materials such as PVC (Polyvinyl chloride), FRP (Fiber Reinforced Polymer or Fiber Reinforced Plastic, fiber reinforced composite material), etc.

[0042] The inner blade 1 is a prefabricated concrete wall panel, which is not only a part of the shear wall, but also serves as an inner formwork during the construction stage. Preferably, the thickness of the inner blade 1 is 50 mm. Figure 1 and Figure 4 As shown, a steel bar 11 is provided inside the inner blade 1. In this embodiment, the inner blade 1 is provided only on one side of the prefabricated wall panel component 2, which can effectively reduce the weight by more than 50% compared with the fully prefabricated or double-layer laminated shear wall panel prefabricated components. The light weight of the components reduces the production and transportation costs and the tower crane costs (the tower crane selection can be selected with a lower tonnage, which reduces the cost).

[0043] The prefabricated wall panel component 2 is first produced in a factory as a prefabricated component, and then transported to the site to be formed by pouring concrete in the inner cavity of the prefabricated component. Figure 1 and Figure 4 As shown, the prefabricated wall panel component 2 is provided with a steel truss 21 and a shear wall distribution bar 22, and the steel truss 21 extends into the inner leaf plate 1. The insulation board 3 is also used as an external formwork during the construction stage. A single-layer insulation board or a double-layer composite insulation board can be used. Figure 1 As shown, a mortar layer 5 , a plastering layer and a finishing layer 6 are provided on the outer side of the thermal insulation board 3 .

[0044] In this embodiment, the inner blade 1 and the prefabricated wall panel component 2 are connected by steel bar overlap or steel bar mechanical connection, which has high installation efficiency and controllable construction quality compared with the sleeve grouting connection method commonly used in the full prefabricated shear wall, and can avoid the steel bar connection construction quality problems caused by improper worker quality or management. At the same time, the inner blade 1 and the insulation board 3 can be used as templates during the construction process, reducing the support of the on-site template, and the insulation is installed in place at the same time, and the post-pasting process is also eliminated, which improves the construction and installation efficiency and reduces the template and labor costs.

[0045] The exterior wall of this embodiment has good durability and adopts integrated exterior wall insulation technology. After pouring concrete in the cavity of the prefabricated wall panel component 2, the insulation board 3 is completely bonded to the structural layer, and an integrated kit 4 is provided to anchor the insulation board 3. This can effectively solve the problems of insulation hollowing, cracking, and falling off, and can conditionally achieve the same lifespan of the insulation and the structure.

[0046] like Figure 4 and Figure 5As shown, the thermal insulation integrated assembled composite shear wall also includes tension bolts 7 and back-stitching members 8 in the prefabrication stage. The back-stitching members 8 are arranged on the outside of the thermal insulation board 3. The tension bolts 7 pass through the through holes 4211 to connect the inner blade 1, the prefabricated wall panel member 2, the thermal insulation board 3 and the back-stitching members 8 together. The back-stitching members 8 provide rigidity for the thermal insulation board 3 during the concrete pouring process of the prefabricated wall panel member 2, and can be removed and reused after the pouring is completed. Preferably, the back-stitching members 8 are made of hard materials such as steel and FRP.

[0047] Specifically, when the shear wall does not have window openings, Figure 6 As shown, the back-ribbed component 8 includes a first block 81 and a second block 82. The size of the first block 81 is 500mm*1100mm, and the size of the second block 82 is 500mm*500mm. Three layers of blocks are arranged along the height direction of the prefabricated wall panel component 2. The bottom layer is four first blocks 81 evenly distributed along the width direction of the prefabricated wall panel component 2. The middle layer is four first blocks 81 evenly distributed along the width direction of the prefabricated wall panel component 2. The top layer is four second blocks 82 evenly distributed along the width direction of the prefabricated wall panel component 2. The second blocks 82 are connected to adjacent first blocks 81 by fastening bolts. The length direction of the first block 81 and the length direction of the second block 82 are consistent with the height direction of the prefabricated wall panel component 2.

[0048] Furthermore, when the shear wall has window openings, Figure 7 As shown, the back-ribbed component 8 also includes a third block 83, the size of the third block 83 is 500mm*700mm, and three layers of blocks are arranged along the height direction of the prefabricated wall panel component 2. The bottom layer is two first blocks 81 on both sides along the width direction of the prefabricated wall panel component 2, and two third blocks 83 are arranged in the middle. The length direction of the first block 81 and the length direction of the third block 83 are consistent with the height of the prefabricated wall panel component 2; the middle layer is a first block 81 on both sides along the width direction of the prefabricated wall panel component 2, and the length direction of the first block 81 is consistent with the height of the prefabricated wall panel component 2; the top layer is two first blocks 81 on both sides along the width direction of the prefabricated wall panel component 2, and a second block 82 is arranged in the middle. The second block 82 is connected to the first block 81 adjacent to the same layer by fastening bolts, and the length direction of the second block 82 is perpendicular to the width direction of the prefabricated wall panel component 2. It should be noted that a weight reduction block 9 is provided on the third block 83.

[0049] The combination of the first block 81, the second block 82 and the third block 83 can meet the requirements of most prefabricated wall panel components with a building height of 2.7 to 3.0 meters.

[0050] The structure of the block is described below by taking the structure of the first block 81 as an example. Figure 8As shown, the first block 81 includes a transverse rib 811, a longitudinal rib 812, a side rib 813, a panel 814, an oblong hole 815 and a fastening bolt hole 816. The transverse rib 811 is arranged along the length direction of the longitudinal rib 812. The panel 814 is installed in the area separated by the transverse rib 811 and the longitudinal rib 812. The side rib 813 forms a frame and is arranged around the grid structure formed by the transverse rib 811, the longitudinal rib 812 and the panel 814. The oblong hole 815 is arranged on the longitudinal rib 812 for installing the connecting rod 42 (the tension bolt 7 is installed in the through hole 4211). The fastening bolt hole 816 is arranged on the side rib 813 for installing the tension bolt 7. It should be noted that, as Figure 8 , Fig. 9 and Fig.10 As shown, the structures of the second block 82 and the third block 83 are similar to those of the first block 81 and are not described in detail herein.

[0051] The connector system of this embodiment includes an integrated kit 4, tension bolts 7, and back-ribbed members 8. The integrated kit 4, tension bolts 7, and back-ribbed members 8 together ensure the safety of the prefabricated wall panels during hoisting, transportation, and construction and installation. The integrated kit 4 bears the deadweight of the insulation board 3 and the back-ribbed member 8, and acts as a limiter for the insulation board 3 and the back-ribbed member 8. During the hoisting and transportation process, the wall panels are vertical, and the insulation board 3 and the back-ribbed member 8 need to be attached to the inner leaf plate 1 through the integrated kit 4 and tension bolts 7, that is, their deadweight needs to be borne by the integrated kit 4 and finally transferred to the inner leaf plate 1.

[0052] The thermal insulation integrated assembled composite shear wall of this embodiment is suitable for assembling an integral shear wall structure system and is used as the exterior wall of a building. The interior wall structure can adopt a cast-in-place shear wall structure, a composite shear wall, or a solid prefabricated shear wall, and the floor system can adopt a composite floor. The industrially produced structural thermal insulation integrated single-sided composite exterior wall panels, prefabricated interior wall panels, composite floor slabs and other components are connected by post-cast concrete and reliable stress-bearing steel bar connection technology to form an assembled integral shear wall structure, ensuring that the structure has the same ductility, bearing capacity and durability as the cast-in-place concrete structure.
