Description

Technical Field

[0001] This utility model relates to the field of shear wall technology, specifically to a bidirectional hollow composite shear wall. Background Technology

[0002] Shear walls are a common building structural component, specifically referring to wall structures in building structures that primarily bear horizontal loads (such as wind loads and seismic loads) and vertical loads (such as floor loads and roof loads).

[0003] Shear walls are widely used in high-rise buildings, multi-story buildings, and large public buildings, playing a vital role in modern building structures. Through their stiffness and strength, shear walls transfer loads to the foundation, thereby ensuring the stability and safety of the building.

[0004] Currently, shear walls are typically assembled using traditional methods, such as using cement or concrete as an adhesive. This method is labor-intensive and time-consuming. Utility Model Content

[0005] The purpose of this invention is to provide a bidirectional hollow composite shear wall to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A bidirectional hollow composite shear wall includes a wall body, wherein a steel reinforcement skeleton assembly is provided inside the wall body, the steel reinforcement skeleton assembly is a rectangular frame structure, and a cavity is also provided inside the wall body;

[0008] The wall is made of cast concrete;

[0009] The steel reinforcement cage assembly includes longitudinally arranged vertical distribution bars and transversely arranged horizontal distribution bars.

[0010] The cavity is formed by a steel frame assembly and a wall, and the cavity is open from top to bottom to form a two-way hollow structure.

[0011] In a further preferred embodiment of this utility model, a shrinkage rib is fixedly connected to the upper end of the vertical distribution rib, and a lap rib is fixedly connected to the upper end of the shrinkage rib, and the lap rib and the shrinkage rib are arranged on the outside of the wall.

[0012] In a further preferred embodiment of this utility model, each end of the horizontal distribution bar is provided with a hook bar, and the hook bars are provided on the outside of the wall.

[0013] In a further preferred embodiment of this utility model, the surface of the horizontal distribution reinforcement is fixedly overlapped with tie bars, and the tie bars are disposed inside the wall.

[0014] In the above technical solution, the beneficial effects of the bidirectional hollow composite shear wall provided by this utility model are as follows:

[0015] 1. This utility model reduces the solid part of the wall by setting a cavity inside the wall, thereby reducing the density of the wall and reducing the self-weight of the wall to reduce the inertial force of the wall under earthquake. At the same time, it also helps to make vertical overlapping between walls by using the cavity, making the splicing between walls more convenient.

[0016] 2. When two walls are joined vertically, the lap joint bars and shrinkage diagonal bars of this utility model are stretched open by their own elasticity to resist the cavity of the opposite wall, thereby strengthening the connection between the two walls.

[0017] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this disclosure.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0027] Please see Figures 1-4 A bidirectional hollow composite shear wall includes a wall 1, a steel reinforcement skeleton assembly is provided inside the wall 1, the steel reinforcement skeleton assembly is a rectangular frame structure, and a cavity 101 is also provided inside the wall 1.

[0028] Wall 1 is made of cast concrete;

[0029] The steel reinforcement cage assembly includes longitudinally arranged vertical distribution bars 2 and transversely arranged horizontal distribution bars 4;

[0030] The cavity 101 is formed by a steel frame assembly and a wall 1, and the cavity 101 is open from top to bottom to form a two-way hollow structure.

[0031] This utility model reduces the solid portion of the wall 1 by setting a cavity 101 inside the wall 1, thereby reducing the density of the wall 1 and reducing the self-weight of the wall 1 to reduce the inertial force of the wall 1 under earthquake action. At the same time, it also helps the walls 1 to be vertically overlapped by using the cavity 101.

[0032] Furthermore, the void ratio formed by cavity 101 is greater than or equal to 30%.

[0033] In a further embodiment of this utility model, a shrinkage rib 202 is fixedly connected to the upper end of the vertical distribution rib 2, and a lap rib 201 is fixedly connected to the upper end of the shrinkage rib 202. The lap rib 201 and the shrinkage rib 202 are arranged outside the wall 1.

[0034] Furthermore, when the two walls 1 are joined together vertically, the lap joint 201 and the shrinkage diagonal rib 202 are stretched open by their own elasticity to resist the cavity 101 of the opposite wall 1, thereby strengthening the connection between the two walls 1.

[0035] In a further embodiment of this utility model, each end of the horizontal distribution bar 4 is provided with a hook bar 401, and the hook bar 401 is provided on the outside of the wall 1.

[0036] Specifically, the hook reinforcement 401 enhances the bond between the wall 1 and other concrete, thereby improving the integrity and stability of the wall 1.

[0037] In a further embodiment of this utility model, a tie bar 3 is fixedly overlapped on the surface of the horizontal distribution rib 4, and the tie bar 3 is disposed inside the wall 1.

[0038] Furthermore, the tie bar 3 connects the horizontal distribution bars 4 on both sides to ensure the transmission and balance of stress between the reinforcing bars.

[0039] Specifically, when wall 1 is subjected to horizontal loads such as wind loads or seismic loads, the tie rod 3 can play a role in transferring shear force, thereby helping to maintain the integrity of wall 1 during the stress process.

[0040] In this utility model, when two wall sections 1 need to be stacked, one wall section 1 is vertically connected above the other wall section 1, and the lap bar 201 of the lower wall section 1 extends into the cavity 101 of the upper wall section 1, so that the shrinkage diagonal bar 202 continuously abuts against the cavity 101 of the upper wall section 1, and then the subsequent processes are carried out, thereby strengthening the connection strength between the two wall sections 1; when the left and right sides of the wall section 1 need to be connected, the hook bar 401 enhances the connection strength between the wall section 1 and other concrete.

[0041] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
