Description

Technical Field

[0001] The utility model relates to the technical field of structural assembly design, in particular to a prefabricated composite shear wall straight thread sleeve vertical connection structure. Background Art

[0002] The Outline of the 13th Five-Year Plan of my country proposes that we must firmly establish and implement the new development concept of innovation, coordination, greenness, openness and sharing, among which green development has become the main theme of the implementation of the Outline. The construction industry is one of the three high-energy-consuming industries, generating more than 300 million tons of new construction waste each year; in addition, there is currently 30%-40% resource waste in China's construction industry, and nearly half of the world's steel and cement are consumed in the construction industry each year, while the average life span of Chinese buildings is only 25 to 30 years. With the influence of environmental protection, population, technology and other factors, the development of prefabricated buildings is unstoppable, including prefabricated composite shear walls.

[0003] However, it still has the following disadvantages in actual use:

[0004] The existing technical research on prefabricated buildings is still based on a closed system, which has the disadvantages of low integration, limited structural forms, and lack of design flexibility. At the same time, the existing vertical steel bar overlap method in the composite shear wall is not convenient for force transmission, and cannot effectively transfer the force in the upper shear wall to the lower layer, and the steel bars in the wall cannot be accurately positioned on site. Utility Model Content

[0005] The purpose of the utility model is to provide a prefabricated composite shear wall straight threaded sleeve vertical connection structure to solve the problem that the technical research of the existing prefabricated buildings mentioned in the above background technology is still a locking system, with the disadvantages of low integration, limited structural forms, and lack of design flexibility. At the same time, the vertical steel bar overlap method in the existing composite shear wall is not convenient for force transmission, and the force in the upper shear wall cannot be effectively transmitted to the lower layer, and the steel bars in the wall cannot be accurately positioned on site.

[0006] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0007] The utility model is a prefabricated composite shear wall straight thread sleeve vertical connection structure, comprising:

[0008] A connection component, the connection component comprising an upper shear wall, a lower shear wall, and a floor slab;

[0009] The upper shear wall is connected above the floor slab, and the lower shear wall is fixed below the floor slab.

[0010] Furthermore, an upper layer of steel bars is fixedly connected inside the upper layer of shear wall, and a lower layer of steel bars is fixedly connected inside the lower layer of shear wall.

[0011] Furthermore, the lower layer of steel bars penetrates the top of the floor slab and extends to the interior of the upper layer of shear walls.

[0012] Furthermore, a connection hole is opened inside the upper shear wall, and the connection hole is a T-shaped hole.

[0013] Furthermore, a sleeve is threadedly connected to the top of the lower steel bar, and the top of the sleeve is rotatably connected to the upper steel bar.

[0014] Furthermore, vertical grooves are provided on both sides of the bottom of the connecting hole, and the sleeve is placed inside the vertical grooves;

[0015] A cast-in-place area is provided inside the floor slab.

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] 1. The utility model optimizes the vertical reinforcement connection mode from indirect overlap to mechanical connection, sets a solid blocking area at the bottom of the original composite shear wall component, opens a connection hole in this area, and opens vertical grooves on both sides of the bottom of the connection hole. The solid blocking method can be used as a component template. The connection hole ensures that the concrete can be poured downwards densely. The reinforcement inside the vertical groove is connected with a straight threaded sleeve, which solves the force transmission problem of indirect overlap of the vertical reinforcement, so that the internal force of the upper shear wall can be effectively transmitted to the lower layer. At the same time, the amount of on-site reinforcement insertion engineering is reduced, and the problem of too dense spacing of the reinforcement inside the cavity is solved. There is no need to accurately position the reinforcement on site, which solves the problem of inaccurate reinforcement positioning. The force mechanism is clear, easy to install, and stable performance, thereby improving the integration degree, opening up structural forms, and improving design flexibility.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
