Description

TECHNICAL FIELD

[0001] The utility model relates to prefabricated wall technical field, concretely relates to a full assembled prefabricated shear wall. BACKGROUND

[0002] In traditional building structures, shear walls serve as an important anti-stress component and are widely used in high-rise buildings and seismic fortification areas. Traditional shear wall construction usually adopts the method of site pouring. Although this method can ensure the integrity of the structure, it also has many problems, such as long construction period, difficult quality control, serious environmental pollution, etc. With the advancement of building industrialization, prefabricated building technology has gradually become the development trend of the construction industry. As a new type of building structure, full assembled prefabricated shear wall has attracted widespread attention due to its fast construction speed, controllable quality, environmental protection and energy saving, etc.

[0003] The core of full assembled prefabricated shear wall is to complete the production of the wall in advance through factory prefabrication, and then assemble it on the construction site. This construction method not only greatly shortens the construction period, but also reduces the complexity and uncertainty of on-site construction. However, the design and construction of prefabricated shear wall still face some technical challenges, especially in terms of seismic performance and crack control. When subjected to earthquake action, traditional prefabricated shear wall often forms a plastic region at the bottom of the wall, resulting in shear force concentration and crack generation, which affects the overall performance and safety of the structure.

[0004] In order to solve the above problems, researchers have proposed a new design method for full assembled prefabricated shear wall. This method effectively reduces the shear force concentration phenomenon of the plastic region at the bottom of the wall by setting a support frame inside the prefabricated wall, and inhibits the generation of cracks. Specifically, the design of the support frame can transfer part of the shear force to the upper area of the wall, thereby dispersing the shear force concentration at the bottom and improving the overall seismic performance of the wall. In addition, the presence of the support frame can also enhance the overall stiffness of the wall, reduce the deformation of the wall during loading, and further inhibit the generation of cracks. SUMMARY

[0005] In order to solve the above problems, the utility model embodiment provides a full assembled prefabricated building wall with strong structural stability.

[0006] The embodiment of the utility model discloses in order to realize above-mentioned purpose, specifically adopt following technical scheme: a full assembly type prefabricated shear wall, including several first and last joint assembly wall, the connecting piece is set between two adjacent assembly walls, the inside of assembly wall is provided with support framework, the both ends of support framework are provided with support beam, the bottom of support framework is provided with the position-avoiding frame for placing connecting piece, the top of position-avoiding frame is provided with the reinforcing rib rib that connects with support framework, the middle part of support framework is provided with pull rod.

[0007] As a further improvement of the above technical solution:

[0008] The support framework is formed by welding a plurality of horizontal ribs and vertical ribs, and the number of the support framework is two and is distributed in a staggered manner along the thickness direction of the assembly wall.

[0009] The pull rod is arc-shaped and abuts against the inner side walls of the two support beams at both ends, the number of the pull rod is two, and the pull rod is symmetrically distributed along the center line of the assembly wall.

[0010] The top of the position-avoiding frame is provided with anchor rods extending into the support framework, the number of the anchor rods is multiple and is symmetrically distributed about the center line of the position-avoiding frame.

[0011] The connecting piece includes a wall shoe arranged at the bottom of the position-avoiding frame and a positioning rod located at the top of the assembly wall and corresponding to the position of the wall shoe, the middle part of the wall shoe is provided with a through hole, and the top of the wall shoe is provided with a locking piece.

[0012] The locking piece includes a backing plate and a locking bolt, and the middle part of the backing plate is provided with a through hole coaxially distributed with the locking bolt.

[0013] The full assembly type prefabricated shear wall can improve the overall strength of the assembly wall, reduce the shear force of the plastic area at the bottom of the wall body, and inhibit the generation of cracks in the wall body.

[0014] The use of the connecting piece can quickly complete the on-site assembly of the assembly wall, reduce the carbon emission of the on-site construction, and save the time cost of the construction of the pouring formwork and the disassembly, thereby improving the work efficiency.
