Prefabricated shear wall tooth groove type connecting structure

Abstract

The invention relates to the technical field of building construction, in particular to a prefabricated shear wall tooth groove type connecting structure which comprises a shear wall body, first protrusions arranged at the top of the shear wall body at intervals and second protrusions arranged at the bottom of the shear wall body at intervals. A first notch used for containing the corresponding second protrusion of the shear wall body on the upper layer is formed between every two adjacent first protrusions, and each first notch is provided with a first sleeve installation hole extending into the shear wall body. A second notch used for containing the corresponding first protrusion of the shear wall body on the lower layer are formed between every two adjacent second protrusions, and each second notch is provided with a second sleeve installation hole extending into the shear wall body. According to the prefabricated shear wall tooth groove type connecting structure provided by the invention, through the mode that the first protrusions are connected with the first notches in a matched mode and the second protrusions are connected with the second notches in a matched mode, the shear wall is convenient to install and position vertically, the installation efficiency is high, and the installation effect is good.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an assembled shear wall alveolar connection structure. Background technique [0002] Shear walls are also called wind-resistant walls, seismic walls or structural walls. Walls in houses or structures that mainly bear horizontal loads and vertical loads caused by wind loads or earthquakes to prevent structures from being damaged by shearing. The prefabricated shear wall has been widely used due to its high degree of mechanization, reliable quality, convenient construction, energy saving and environmental protection. However, the existing prefabricated shear walls have the following defects during installation: [0003] 1. The positioning of the upper and lower shear walls is difficult, making it difficult for the steel bars pre-embedded in the upper wall to be inserted into the grouting sleeves pre-embedded in the lower wall, so that the installation efficiency of ...

AI Technical Summary

Problems solved by technology

[0003] 1. The positioning of the upper and lower shear walls is difficult, making it difficult for the steel bars pre-embedded in the upper wall to be inserted into the grouting sleeves pre-embedded in the lower wall, thus making the installation efficiency of the upper and lower shear walls low

[0004] 2. The connection nodes of the upper and lower shear walls are located on the same horizontal line, which makes the seismic effect of the assembled shear wall poor

[0005] 3. The left and right shear walls have low installation efficiency and poor connection effect

The installation of the shear wall does not need to consider the interference of the horizontal ribs. After the shear wall is placed, insert the driving rod into the straight groove, and under the action of the driving rod, the connecting rod will move to the left through the driving rod to protrude the shear wall. Force wall, this structure can speed up the installation speed of the left and right shear walls to a certain extent, but the effect is not very obvious, so further improvement is needed on the left and right connection structures of the existing shear walls

In addition, it does not propose a solution on how to improve the installation efficiency of the upper and lower shear walls and how to improve the seismic effect of the shear walls

[0008] The patent with the application number CN202020316896.5 discloses a type of up and down quick assembly shear wall, the bottom of the upper shear wall is crimped with the top of the lower shear wall, and the inner cavity of the upper shear wall is provided with a first chute , the inner surface of the first chute is slidably connected with a first slide plate, the bottom of the first slide plate is fixedly connected with a slide bar, the pressing bar and the fixing bar fix the position of the J-shaped bar, and then cooperate with the positioning bar to adjust the position of the J-shaped bar. The position of the positioning column is fixed, so as to fix the relative position of the second slide plate and the lower shear wall. The first chute facilitates the sliding of the first slide plate, thereby facilitating the sliding of the slide bar and the second slide plate. The position of the second slide plate is fixed , the positions of the first sliding plate and the upper shear wall are stable, and then cooperate with the sliding bar to fix the relative position of the upper shear wall and the lower shear wall. Although the shear wall structure can solve the positioning problem, the overall The structure is complex, the operation is inconvenient, and it cannot effectively improve the installation efficiency of the upper and lower shear walls

In addition, it does not propose a solution on how to improve the installation efficiency of the left and right shear walls and how to improve the seismic effect of the shear walls
