Horizontal connecting node structure of T-shaped shear wall

Abstract

The invention discloses a horizontal connecting node structure of a T-shaped shear wall, comprising a first prefabricated shear wall and a second prefabricated shear wall, wherein a T-shaped structure is formed between the first prefabricated shear wall and the second prefabricated shear wall; the first prefabricated shear wall and the second prefabricated shear wall are separated at nodes for a certain distance and respectively provided with a first horizontal steel bar and a second horizontal steel bar internally; a groove is arranged at the node of the second prefabricated shear wall, and cast-in-situ concrete is filled the separation part of the groove and the prefabricated shear walls; the first horizontal steel bar extends into the cast-in-situ concrete from the first prefabricated shear wall and bends inwards when going to the edge of the second prefabricated shear wall; and an embedded column stirrup is arranged in the second prefabricated shear wall and also extends into the cast-in-situ concrete. The invention has simple structure, convenient construction and low cost, realizes that the first prefabricated shear wall and the second prefabricated shear wall form an integer by extending the first horizontal steel bar and arranging the embedded column stirrup in the second prefabricated shear wall, can well bear the external force in a horizontal direction and has the characteristics of shock resistance and safety.

Description

technical field [0001] The invention relates to a horizontal connection node structure of a T-shaped shear wall, and belongs to the technical field of building structures. Background technique [0002] Shear wall is a wall made of reinforced concrete. The structure of shear wall that bears vertical and horizontal action becomes a shear wall structure. One of the important functions of shear wall is to resist horizontal action, and The horizontal shear force to be resisted by a high-rise building is only caused by an earthquake, so the shear wall can effectively control the horizontal shear force of the structure, resist damage and earthquake. The shear wall and the shear wall need to be connected as a whole to keep it continuous. Under the action of external forces such as earthquake force, the horizontal shear force and vertical reaction force can be transmitted. The connection between the shear walls is very important, and the current horizontal connection between the she...

Problems solved by technology

However, the shear wall and the shear wall need to be connected as a whole to keep it continuous. Under the action of external forces such as earthquake force, the horizontal shear force and vertical reaction force can be transmitted. Therefore, the shear wall The connection between the shear walls is very important, and the current horizontal connection nodes between the shear walls mostly use horizontal steel bars and vertical steel bars in the shear walls, which makes the amount of steel bars large and the cost is high , and the ability to transmit external forces in the horizontal direction is limited
