Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated concrete components, in particular to a prefabricated shear wall connection structure. Background Art

[0002] With the development of modern industry and the emergence of more and more high-rise buildings, the design of houses has gradually transformed from cast-in-place to prefabricated assembly. Concrete prefabricated structure uses concrete as the main structure, relying on nodes and joints to connect the structure into a whole and meet the bearing capacity, stability, rigidity, ductility and other requirements of the use stage and the construction stage at the same time. It has the advantages of low project cost, high construction efficiency, green and environmental protection. Nowadays, prefabricated housing is the development trend of my country's construction industry.

[0003] The connection technology of prefabricated shear wall structures includes two aspects: one is the connection between components, and the other is the connection between the structure and the foundation. The connection between components is usually made by bolt connection or welding. Bolt connection is suitable for structures that need to be disassembled, and welding connection is suitable for structures that require tighter connection. The connection between the structure and the foundation usually adopts the following connection methods: anchor connection and embedded connection. Anchor connection is to connect the prefabricated shear wall structure to the concrete foundation through bolts or welding, while embedded connection is to reserve connecting parts in the concrete foundation, and then connect the prefabricated shear wall structure to the reserved connecting parts.

[0004] When the existing prefabricated shear wall connection structure is spliced up and down, it is necessary to lift the upper shear wall by machinery, and then install it on the bottom shear wall with manual labor, and then fix the two by the structure between the shear walls. However, the existing shear wall has a low connection strength at the connection structure between the upper shear wall and the lower shear wall because the spliced parts are too flat, resulting in low overall structural strength of the wall. Utility Model Content

[0005] The purpose of this application is to solve the problem that the connection strength of the connection structure between the upper shear wall and the lower shear wall is not high because the joints between the existing shear walls are too flat.

[0036] When the prefabricated shear walls are connected up and down through this structure, the bottom shear wall is installed on the ground, and then the other shear wall is lifted by the crane tool, and then the crane is controlled to move it to the top of the bottom shear wall, and then the position of the lifted shear wall is adjusted manually so that the arc strip 12 of the bottom shear wall enters the arc groove of the lifted shear wall, and the shielding plate 6 blocks the gap between the two shear walls, and then the process of installing the shear wall is guided by the installation structure, and then the two are fixed through the installation structure, and finally the steel bars are inserted from the steel bar holes 13 of the two to connect the adjacent shear walls, which makes the device more convenient in the process of shear wall installation and also improves the connection strength between the shear walls.

[0037] Reference Figure 1 and Figure 2 、 Figure 3 The mounting structure includes a tapered bar 9 fixedly connected to the top of the wall 1. The tapered bar 9 is fixedly connected to the curved bar 12. A tapered groove is provided at the bottom of the wall 1. The tapered groove is connected to the curved groove, and the tapered groove is adapted to the tapered bar 9. A limit pin 11 is fixedly connected to the curved bar 12. A limit groove 17 is provided inside the curved groove. The limit pin 11 is adapted to the limit groove 17. A connecting groove 10 is provided on the curved bar 12. A connecting groove is provided on the wall 1. The connecting groove corresponds to the curved groove. A threaded rod 16 is provided in the connecting groove 10 and the connecting groove. The end of the threaded rod 16 is fixedly connected to the handle 5. A threaded sleeve 14 is fixedly connected in the connecting groove. The threaded sleeve 14 is adapted to the threaded rod 16.

[0038] When the shear wall is installed up and down, the arc groove on the upper wall 1 is first matched with the arc strip 12 at the lower end, and then the upper wall 1 is lowered by a crane. During the lowering process, the arc strip 12 is guided by the tapered groove to move toward the position of the arc groove, and then enters the inside of the arc groove and enters the limiting groove 17 through the limiting nail 11, making the installation of the arc groove more stable, reducing the manual guidance during the installation between the upper and lower shear walls, and allowing it to automatically limit the arc groove and the arc strip 12 when it falls freely. Then, the threaded rod 16 is extended from the connecting groove into the connecting groove 10 to pass through the arc strip 12, and then one end of it is turned into the threaded sleeve 14 to limit the two shear walls. Through multi-directional limitation, the installation of the shear wall is simpler and the connection strength of the shear wall connection is improved.

[0039] Reference Figure 2 and Figure 3 、 Figure 4 、 Figure 5 The wall 1 is fixedly connected to a top plate 2, and the wall 1 is fixedly connected to a bottom plate 7. The top plate 2 is adapted to the bottom plate 7. Both the top plate 2 and the bottom plate 7 are provided with fixing grooves, and fixing bolts 15 are provided in the fixing grooves. The bottom plate 7 is fixedly connected to a limit plate 4, and the limit plate 4 is fixedly connected to the limit plate 2.

[0040] When the two shear walls are stacked together, the top plate 2 and the bottom plate 7 fit together, and the T-shaped plate 22 is inserted into the top plate 2 along the installation groove 18. As the T-shaped plate 22 moves, the semicircular limit groove 23 thereon moves to the semicircular limit block 21. At this time, the spring 20 resets and pushes the semicircular limit block 21 to move into the semicircular limit groove 23, thereby limiting the position between the top plate 2 and the T-shaped plate 22, thereby pre-fixing the top plate 2 and the bottom plate 7, reducing the shaking of the L shear wall during installation, and then fixing the top plate 2 and the bottom plate 7 on both sides of the fixing groove by the fixing bolts 15, so that the adjacent shear walls are fixed, thereby improving the stability of the shear wall when fixed, making its installation more convenient.

[0041] Working principle: When the shear wall is installed up and down, the arc groove on the upper wall 1 is first matched with the arc strip 12 at the lower end, and then the upper wall 1 is lowered by a crane. During the lowering process, the arc strip 12 is guided by the tapered groove to move toward the position of the arc groove, and then enters the inside of the arc groove and enters the limiting groove 17 through the limiting nail 11, so that the installation of the arc groove is more stable, and the manual guidance during the installation between the upper and lower shear walls is reduced, so that the free fall can automatically limit the position between the arc groove and the arc strip 12, and then the threaded rod 16 is extended from the connecting groove into the connecting groove 10 to pass through the arc strip 12, and then one end of the threaded rod is turned into the threaded sleeve 14 to limit the position between the two shear walls. Through multi-directional limitation, the installation of the shear wall is simpler and the connection strength of the shear wall connection is improved.

[0042] When the two shear walls are stacked together, the top plate 2 and the bottom plate 7 fit together, and the T-shaped plate 22 is inserted into the top plate 2 along the installation groove 18. As the T-shaped plate 22 moves, the semicircular limit groove 23 thereon moves to the semicircular limit block 21. At this time, the spring 20 resets and pushes the semicircular limit block 21 to move into the semicircular limit groove 23, thereby limiting the position between the top plate 2 and the T-shaped plate 22, thereby pre-fixing the top plate 2 and the bottom plate 7, reducing the shaking of the L shear wall during installation, and then fixing the top plate 2 and the bottom plate 7 on both sides of the fixing groove by the fixing bolts 15, so that the adjacent shear walls are fixed, thereby improving the stability of the shear wall when fixed, making its installation more convenient.
