[0002] Shear walls are important components of a building. A shear wall is a wall used to bear horizontal loads and vertical loads caused by wind loads or seismic actions, preventing the structure from being damaged by shear. In the conventional construction process, shear walls are usually constructed on the construction site using bricks and concrete in wet operations, which takes a long time and requires waiting for the concrete to solidify. Moreover, during the operation process, a large number of scaffolds are needed for support, making the construction site messy.

[0003] With the rise of prefabricated buildings, more and more prefabricated components are being applied, and shear walls are typical representatives. Shear walls are prefabricated in the factory and then transported to the construction site, where they are quickly connected to components such as precast columns and precast beams through steel structural members for assembly.

[0049] To make the technical problems, technical solutions and advantages to be solved by the present utility model clearer, the following will be described in detail with reference to the accompanying drawings and specific embodiments.

[0050] As shown in Figures 1-3As shown in the figure, an embodiment of the present utility model provides a shear wall without support, which includes a wall body 10. The wall body 10 is generally rectangular in shape and includes a main wall surface 11, side wall surfaces 12, an upper wall surface 13, and a lower wall surface. Among them, the two main wall surfaces 11 are arranged opposite to each other, the two side wall surfaces 12 are arranged opposite to each other, and the upper wall surface 13 and the lower wall surface are arranged opposite to each other. Connecting steel bars 20 are arranged in the vertical direction of the wall body 10, and a connecting hole 14 is arranged on the lower wall surface. The connecting hole 14 is arranged upward along the vertical direction from the lower wall surface, and the height of the connecting hole 14 is less than half of the height of the wall body 10. The upper end of the aforementioned connecting steel bar 20 penetrates out of the upper wall surface 13 by a part, and the lower end is located in the connecting hole 14. The diameter of the connecting hole 14 is larger than the diameter of the connecting steel bar 20. A grouting hole 15 is also arranged on the main wall surface 11, and the grouting hole 15 communicates with the connecting hole 14.

[0051] A U-shaped unit 30 is also arranged on the wall body 10. There are several groups of U-shaped units 30, and several groups of U-shaped units 30 are arranged at intervals along the vertical direction on the side wall surface 12. Each group of U-shaped units 30 includes one U-shaped steel bar or multiple U-shaped steel bars, and the multiple U-shaped steel bars are arranged along the vertical direction. The U-shaped steel bar includes a free end, and the free end is buried in the wall body 10 so that the U-shaped steel bar encloses a closed area.

[0052] A screwing unit 40 is also arranged on the side wall surface 12. The screwing unit 40 is embedded in the wall body 10. The screwing unit 40 includes a screw tube 41 with internal threads, and the screw tube 41 is arranged between adjacent U-shaped units 30. Preferably, there is at least one screwing unit 40.

[0053] A side plate 16 is also arranged on the side wall surface 12. The side plate 16 is arranged along the vertical direction of the side wall surface 12, and the height of the side plate 16 is the same as the height of the U-shaped unit 30. The side plate 16 is located on one side of any main wall surface 11.

[0054] In this application, the installation of the shear wall without support is convenient, and no other support structures are required for assistance during the installation process. At the same time, the shear wall without support can achieve rapid assembly, improving the assembly speed.

[0055] Furthermore, the screwing unit 40 further includes a reinforcing member 42. The reinforcing member 42 is perpendicularly connected to the screw tube 41, and the reinforcing member 42 and the screw tube 41 are embedded in the wall body 10. When the screwing unit 40 is embedded, one end of the screw tube 41 is partially exposed on the surface of the side wall surface 12 for convenient assembly. The reinforcing member 42 located at the other end of the screw tube 41 is located in the wall body 10. By setting the reinforcing member 42, the connection firmness between the screw tube 41 and the wall body 10 can be effectively improved.

[0056] Preferably, the screwing unit 40 is integrally formed and made of steel material.

[0057] Preferably, an avoidance groove is further provided on the side plate 16, and the avoidance groove is arranged on the side of the side plate 16 close to the U-shaped unit 30. The U-shaped steel bar includes a first connecting section, a second connecting section and an intermediate section. The first connecting section and the second connecting section respectively include a connecting end and a free end. The connecting sections of the first connecting section and the second connecting section are connected to both ends of the intermediate section. The free ends of the first connecting section and the second connecting section are embedded in the wall body 10, and the first connecting section or the second connecting section is located in the avoidance groove.

[0058] The purpose of setting the avoidance groove is to increase the length of the connecting section, so that the area surrounded by the U-shaped steel bar is larger, and more fixing steel bars 60 can be inserted into the surrounded area to enhance the connection strength between two adjacent shear walls.

[0059] When vertically assembling the shear wall, the connecting steel bar 20 of the lower shear wall is inserted into the connecting hole 14 of the upper shear wall, and concrete is injected into the connecting hole 14 through the grouting hole 15 to achieve longitudinal connection.

[0060] Based on the same utility model concept, the present application also discloses a shear wall assembly without support, which is used for at least two shear walls without support to be connected end to end in a straight line, as Figures 4-6 , which respectively include a first shear wall 1A and a second shear wall 1B. Both the first shear wall 1A and the second shear wall 1B are the aforementioned shear walls without support. The side plates 16 of the first shear wall 1A and the second shear wall 1B are arranged on different sides of the U-shaped unit 30. The first shear wall 1A and the second shear wall 1B are connected end to end, and the U-shaped units 30 of the first shear wall 1A and the second shear wall 1B overlap to form an overlapping area. A first connecting member 50A is further provided on the first shear wall 1A and the second shear wall 1B. The first connecting member 50A includes a first rectangular body, a first bolt 51 and a second bolt. A first through hole is provided on the first side surface of the first rectangular body, and a second through hole is provided on the second side surface opposite to the first side surface. The first bolt 51 passes through the first through hole and is screwed with the screw pipe 41 of the first shear wall 1A, and the second bolt passes through the second through hole and is screwed with the screw pipe 41 of the second shear wall 1B. The first connecting member 50A is used to preliminarily connect two adjacent first shear walls 1A and second shear walls 1B.

[0061] In order to facilitate the tightening of the first bolt 51 and the second bolt, an operation hole is further opened on the third side surface and / or the fourth side surface of the first connecting member 50A. The first connecting member 50A is made of steel material.

[0062] The first connecting member 50A extends into the space between the first shear wall 1A and the second shear wall 1B from the interval between the two vertical side plates 16. As the first connecting member 50A is locked, the U-shaped units 30 on the first shear wall 1A and the U-shaped units 30 on the second shear wall 1B overlap to form an overlapping area. At the same time, the sides of the overlapping area are respectively surrounded by the side walls 12 and side plates 16 of the first shear wall 1A and the second shear wall 1B.

[0063] Insert at least one fixing steel bar 60 into the overlapping area and pour concrete into the overlapping area. After the concrete solidifies, the transverse connection between the first shear wall 1A and the second shear wall 1B is completed. During the assembly process, the first connecting member 50A completes the connection between the first shear wall 1A and the second shear wall 1B, and the insertion of the fixing steel bar 60 and the solidification of the concrete further enhance the connection strength between the first shear wall 1A and the second shear wall 1B, making the connection strength between the first shear wall 1A and the second shear wall 1B meet the building code.

[0064] Preferably, both the first through hole and the second through hole are waist-shaped holes, and the projections of the first through hole and the second through hole on the side wall 12 of the first shear wall 1A or the second shear wall 1B are orthogonal.

[0065] The orthogonality of the projections of the first through hole and the second through hole can reduce the assembly accuracy of the first shear wall 1A and the second shear wall 1B, making it easier for the first shear wall 1A and the second shear wall 1B to be assembled together.

[0066] The present application also provides another shear wall assembly without support, such as Figures 7-9 , including a third shear wall 1C and a fourth shear wall 1D. Both the third shear wall 1C and the fourth shear wall 1D are the aforementioned shear walls. The side plates 16 in the third shear wall 1C and the fourth shear wall 1D are arranged on the same side of the U-shaped unit 30. The third shear wall 1C and the fourth shear wall 1D are connected end to end, and the third shear wall 1C is perpendicular to the fourth shear wall 1D. The U-shaped units 30 of the third shear wall 1C and the U-shaped units 30 of the fourth shear wall 1D overlap to form an overlapping area.

[0067] A second connecting member 50B is further included between the third shear wall 1C and the fourth shear wall 1D. The second connecting member 50B includes a second rectangular body, a third bolt 53, and a fourth bolt 54. The first side of the second rectangular body is provided with a first through hole, and the second side is provided with a second through hole. The first side and the second side are adjacent. The third bolt 53 passes through the first through hole and is screwed to the screw pipe 41 in the third shear wall 1C, and the fourth bolt 54 passes through the second through hole and is screwed to the screw pipe 41 in the fourth shear wall 1D.

[0068] The second connecting member 50B is used to preliminarily connect the adjacent third shear wall 1C and fourth shear wall 1D. The second connecting member 50B is made of steel material.

[0069] To facilitate the tightening of the third bolt 53 and the fourth bolt 54, an operation hole is provided on the third side surface and / or the fourth side surface of the second connecting member 50B.

[0070] The second connecting member 50B extends into the space between the third shear wall 1C and the fourth shear wall 1D from the area spaced by the side plates 16 of the third shear wall 1C and the fourth shear wall 1D. As the second connecting member 50B is tightened, the U-shaped units 30 on the third shear wall 1C and the U-shaped units 30 on the fourth shear wall 1D overlap to form an overlapping area. At the same time, the lateral sides of the overlapping area are respectively surrounded by the side wall surfaces 12 and the side plates 16 of the third shear wall 1C and the fourth shear wall 1D.

[0071] Insert at least one fixing steel bar 60 into the overlapping area, and pour concrete into the overlapping area. After the concrete solidifies, the connection between the third shear wall 1C and the fourth shear wall 1D is completed. Similarly, the insertion of the fixing steel bar 60 and the solidification of the concrete further enhance the connection strength between the third shear wall 1C and the fourth shear wall 1D, making the connection strength between the third shear wall 1C and the fourth shear wall 1D meet the building codes.

[0072] Preferably, both the first through hole and the second through hole are waist-shaped holes. The first through hole is horizontally arranged, and the second through hole is vertically arranged, or the first through hole is vertically arranged and the second through hole is horizontally arranged.

[0073] The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle described in the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
