Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, and in particular to a crack-resistant and anti-detachment device for composite shear wall connection nodes. Background Technology

[0002] Crack-resistant and anti-detachment devices for shear wall connection nodes effectively slow down or prevent crack propagation at connection nodes and prevent wall detachment or shear failure, thereby improving the seismic performance of the entire shear wall structure. The device increases the stability of the connection node, reduces the risk of structural instability due to crack propagation, and improves the load-bearing capacity of the connection node and the overall structural stability. The device effectively protects the connection node from external environmental factors such as wind and rain erosion and chemical corrosion, thus improving the durability and long-term stability of the structure. Crack-resistant and anti-detachment devices typically have good reliability and durability, reducing the frequency and workload of maintenance and repair work, and lowering maintenance costs. Enhancing the stability of connection nodes and the overall seismic performance of the structure can improve building safety, reduce the risk of accidents, and protect the safety of people and property. Crack-resistant and anti-detachment devices for shear wall connection nodes effectively improve the seismic performance, stability, and durability of the structure, extend the service life of the structure, reduce maintenance and repair costs, and improve the safety and reliability of the building.

[0003] Existing technology discloses a crack-prevention structure at the connection between a shear wall and an infill wall, comprising: a shear wall with a tongue and groove joint at one end, a first positioning groove inside the shear wall, an angle steel at the other end of the tongue and groove joint, tie bars inside the shear wall, an infill wall at one end of the shear wall, and a second positioning groove inside the infill wall; and a tension plate located at one end of the tongue and groove joint. By pre-reserving a tongue and groove joint at the connection between the shear wall and the infill wall, a certain transition distance is provided for the plastering at the connection, changing the original three materials at the connection to two materials: masonry and concrete, reducing the possibility of cracking. Furthermore, the tie bars and tension plate provide tensile strength to both the shear wall and the infill wall. However, the structural components and the shear wall do not fit well together, thus reducing the crack-prevention and anti-detachment effect. Therefore, the existing technology still has shortcomings and deficiencies. How to provide a crack-prevention and anti-detachment device for a composite shear wall connection node that can fit well with the shear wall is a technical problem that urgently needs to be solved by those skilled in the art.

The fastener can be a bolt or a screw, etc. In this embodiment, the first connecting block 12 is provided with a first bolt 121, which is used to connect with the wall surface of the superposed shear wall.

[0029] The fitting assembly is provided on the main body 10, and the fitting assembly includes a screw rod 22, a sliding plate 23, an extension column 26 and a resistance plate 27.

When the screw rod 22 rotates, the extension column 26 is moved through the sliding plate 23, so that the resistance plate 27 approaches or moves away from the wall surface of the superposed shear wall.

[0030] In use, the superposed shear wall connecting joint anti-cracking and anti-falling device provided in this embodiment is arranged on one side of the superposed shear wall, the first connecting block 12 on the main body 10 is connected with the wall surface of the superposed shear wall through the first bolt 121, the sliding plate 23 is moved along a straight line through the rotation of the screw rod 22, and then the extension column 26 is moved along a straight line, so that the resistance plate 27 is attached to the wall surface of the superposed shear wall.

The resistance plate 27 is fully attached to the wall surface of the superposed shear wall, so as to guarantee the effect of anti-cracking and anti-falling.

[0031] Referring to Figures 1 to 4 The anti-cracking and anti-falling device for the connecting joint of the laminated shear wall provided by the embodiment further comprises a mounting plate 13 movably arranged in the main body 10. The main body 10 is provided with an inner cavity, and the mounting plate 13 is at least partially accommodated in the inner cavity of the main body 10. The mounting plate 13 enters the inner cavity of the main body 10 from the lower part of the main body 10, and the mounting plate 13 can move in the vertical direction along the main body 10 in the above-mentioned inner cavity, so as to adjust the length of the mounting plate 13 extending out of the inner cavity of the main body 10.

[0040] The protection box 20 is located on the side of the main body 10, and the servo motor 21 is installed in the protection box 20. The protection box 20 provides protection for the servo motor 21 and other components, prevents the servo motor 21 from being eroded by water, sand, dust, corrosion and other pollutants, improves stability and reliability, and prolongs the service life of the device. The servo motor 21 outputs rotary motion to drive the screw rod 22 to rotate, and then drives the abutting plate 27 on the other side of the main body 10 to move linearly through the sliding plate 23 and the telescopic column 26, so that the abutting plate 27 is finally attached to the wall surface of the laminated shear wall.

[0041] In addition, the protection box 20 is also provided with a guide rod, and the sliding plate 23 is slidingly connected with the guide rod, which supports and guides the movement of the sliding plate 23.

[0043] For reference Figures 1 to 4 The servo motor 21 is fixedly installed in the protection box 20 through a motor base 211.
