Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and in particular relates to a prefabricated building shear wall. Background Technology

[0002] A shear wall is a type of wall in a building structure that is primarily used to resist horizontal forces. Under the influence of earthquakes or strong winds, buildings are subjected to enormous horizontal thrust or tension (called horizontal loads or lateral forces). Shear walls act as "lateral supports" or "skeletons" for buildings, bearing and transmitting these horizontal forces to prevent buildings from tilting, collapsing, or swaying excessively.

[0003] Typically, prefabricated building shear walls mainly consist of wall panels and reinforcing bars. Simply put, workers leave the ends of the reinforcing bars on two wall panels, and use prefabricated spiral stirrups, straight thread sleeves, and other mechanical connectors to connect the reinforcing bars of the two wall panels together. Then, concrete is poured on the outside of the connectors.

[0004] However, the connection methods between steel bars are usually welding or lap splicing. Among them, lap spliced ​​steel bars transfer stress through the bond force of concrete, which has a large dispersion and relatively low reliability. Under repeated loading such as earthquakes, they are prone to slippage or even pull-out failure. Welding is not suitable for all steel bars, is prone to welding defects, and requires professional welders and equipment, resulting in low construction efficiency. Therefore, a prefabricated building shear wall is needed to solve the above problems. Utility Model Content

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] like Figures 1 to 4 As shown, this utility model embodiment provides a prefabricated building shear wall, including:

[0027] The shear wall body 1 includes wall panels 11 and reinforcing bars 12. There is a pair of wall panels 11 arranged in parallel to each other. There are two sets of reinforcing bars 12, and each set of reinforcing bars 12 has multiple bars. The multiple bars 12 are arranged in parallel at the same interval. One set of reinforcing bars 12 is inserted into the other set of reinforcing bars 12. A connecting hole 121 is provided at the intersection of every two reinforcing bars 12.

[0028] The connecting component 2 is provided in multiple ways. Each connecting component 2 includes a plug rod 21, a sliding plate 22, a connecting rod 23, and a fixing member 24. The plug rod 21 is plugged into two oppositely arranged connecting holes 121. There are two sets of sliding plates 22 and connecting rods 23. Each set of connecting rods 23 has two connecting rods. One end of each set of connecting rods 23 is rotatably connected to one end face of each sliding plate 22. The ends of each set of connecting rods 23 away from the sliding plate 22 are rotatably connected to each other. The sliding plate 22 is slidably arranged on the plug rod 21. The plug rod 21 has a pair of oppositely arranged placement slots 211. The connecting rods 23 are arranged in the placement slots 211. The fixing member 24 is installed on the plug rod 21 and is detachably arranged at the rotatably connected end of each set of connecting rods 23. The end face of the sliding plate 22 away from the connecting rod 23 abuts against the reinforcing bar 12. The two ends of the plug rod 21 abut against each wall panel 11.

[0029] In this embodiment, during installation, firstly, the worker inserts one set of reinforcing bars 12 into another set of reinforcing bars 12, aligning the connecting holes 121 on the reinforcing bars 12. Then, the two ends of the insertion rod 21 are respectively inserted into a pair of opposing connecting holes 121, ensuring that a pair of sliding plates 22 slidably connected to the insertion rod 21 are positioned between the pair of connecting holes 121. At this time, a pair of connecting rods 23 rotatably connected to the pair of sliding plates 22 form an angle of 0° to 180°. After the insertion rod 21 is inserted into the connecting holes 121, the worker slides the pair of sliding plates 22, causing the sliding plates 22 to abut against the reinforcing bars 12. At this time, a pair of connecting rods 23 rotatably connected to the pair of sliding plates 22 form an angle of 180°, and then, using the fixing member 24, the connecting rods 23 are placed in the placement groove 211. In this way, by setting the insertion rod 21 and the sliding plates 22, the two sets of reinforcing bars 12 are fixed together. The operation is simple, applicable to all reinforcing bar 12 materials, and requires no professional personnel or equipment, making it widely applicable.

[0030] Specifically, the fastener 24 includes a fixing plate 241 and a fixing nut 242. Each fixing plate 241 and fixing nut 242 is provided in pairs. The two ends of each pair of fixing plates 241 are fitted together. Each pair of fixing nuts 242 is detachably installed at the two ends of the fixing plate 241. The opposite end faces of each pair of fixing plates 241 abut against one end of each set of connecting rods 23 that are rotatably connected. The inner wall of the fixing plate 241 is fitted against the side wall of the plug rod 21.

[0031] In this embodiment, the worker attaches a pair of fixing plates 241 together and ensures that the opposite end faces of the fixing plates 241 abut against the end of a pair of connecting rods 23 that are rotatably connected. Then, the worker rotates the fixing nut 242 to fix the pair of fixing plates 241 together. In this way, by setting the fixing plates 241 and the fixing nut 242, the sliding plate 22 is prevented from sliding at will, and the stability between the reinforcing bars 12 is further ensured.

[0032] Specifically, the sliding plate 22 has a sliding hole 221, the cross-section of the sliding hole 221 is adapted to the cross-section of the middle section of the plug rod 21, and the inner wall of the sliding hole 221 is in contact with the plug rod 21.

[0033] Specifically, the wall panel 11 also includes a plurality of spaced abutment grooves 111, and the connecting assembly 2 also includes a connecting column 25 and an abutment plate 26. Each connecting column 25 and abutment plate 26 is provided in a pair. Each abutment plate 26 is fixedly connected to one end of each connecting column 25. Each pair of abutment plates 26 is placed in the abutment groove 111 on each pair of wall panels 11. The ends of a pair of connecting columns 25 away from the abutment plate 26 are detachably connected to the two ends of the plug rod 21. The abutment plate 26 abuts against the reinforcing bar 12 at the end face away from the abutment groove 111.

[0034] Specifically, threaded posts 212 are provided at both ends of the plug rod 21, and threaded holes 251 are provided at the end of the connecting post 25 away from the abutment plate 26. The threaded posts 212 are threadedly connected to the threaded holes 251.

[0035] In this embodiment, the worker rotates the abutment plate 26 so that the threaded hole 251 on the connecting post 25 connected to the abutment plate 26 is threadedly connected to the threaded post 212 on the plug rod 21; then a pair of wall plates 11 are placed on both sides of the reinforcing bar 12 to ensure that the abutment plate 26 is placed in the abutment groove 111 of the wall plate 11, ensuring that the position between the wall plate 11 and the reinforcing bar 12 will not easily change; at the same time, the abutment plate 26 abuts against the reinforcing bar 12, at which time each group of reinforcing bars 12 is placed between the abutment plate 26 and the sliding plate 22, further ensuring a more secure connection between the reinforcing bars 12;

[0036] Specifically, the cross-sections of both the sliding plate 22 and the abutment plate 26 are circular.

[0037] The working principle of this utility model is as follows:

[0038] During installation, firstly, the worker inserts one set of reinforcing bars 12 into another set of reinforcing bars 12 so that the connecting holes 121 on the reinforcing bars 12 are aligned with each other; then, the two ends of the insertion rod 21 are respectively inserted into a pair of opposite connecting holes 121, and a pair of sliding plates 22 slidably connected to the insertion rod 21 are placed between the pair of connecting holes 121; at this time, a pair of connecting rods 23 rotatably connected to the pair of sliding plates 22 form an angle of 0° to 180°.

[0039] After the insertion rod 21 is inserted into the connection hole 121, the worker slides a pair of sliding plates 22 so that the sliding plates 22 abut against the reinforcing bar 12; at this time, a pair of connecting rods 23, which are rotatably connected to the pair of sliding plates 22 respectively, form an angle of 180° and are placed in the placement groove 211; in this way, by setting the insertion rod 21 and the sliding plates 22, the two sets of reinforcing bars 12 are fixed to each other; the operation is simple, applicable to all reinforcing bar 12 materials, and does not require professional personnel or equipment, and has a wide range of applications;

[0040] Then, the worker attaches a pair of fixing plates 241 together and ensures that the opposite end faces of the fixing plates 241 abut against the end of the pair of connecting rods 23 that are rotatably connected. Then, the worker rotates the fixing nut 242 to fix the pair of fixing plates 241 together. In this way, by setting the fixing plates 241 and the fixing nut 242, the sliding plate 22 is prevented from sliding at will, and the stability between the steel bars 12 is further ensured.

[0041] Finally, the worker rotates the abutment plate 26 so that the threaded hole 251 on the connecting post 25 connected to the abutment plate 26 is threadedly connected to the threaded post 212 on the plug rod 21; then a pair of wall plates 11 are placed on both sides of the reinforcing bar 12 to ensure that the abutment plate 26 is placed in the abutment groove 111 of the wall plate 11, ensuring that the position between the wall plate 11 and the reinforcing bar 12 will not easily change; at the same time, the abutment plate 26 abuts against the reinforcing bar 12, and at this time each group of reinforcing bars 12 is placed between the abutment plate 26 and the sliding plate 22, further ensuring a more secure connection between the reinforcing bars 12.
