Description

Technical Field

[0001] This utility model relates to a vibration-damping building embedded part, specifically to a connection node between a concrete component and a viscous damper embedded part. Background Technology

[0002] In recent years, the country has been encouraging and supporting the development of seismic isolation and damping technology, and the application of dampers has become more and more widespread, such as viscous dampers. Viscous dampers basically do not occupy the building function, while increasing the additional damping ratio of the structure. They can reduce the amount of reinforcement used in shear walls, beams and columns, and the cross-sectional dimensions of components. They are not only suitable for the seismic and wind resistance of newly built civil engineering structures, but can also be widely used in the seismic reinforcement or post-earthquake repair of existing civil engineering structures.

[0003] As the load-bearing capacity of dampers increases, the reinforced concrete walls connected to the frame beams and the embedded parts at the joints also become larger and heavier to match the load-bearing capacity, making installation and transportation extremely difficult.

[0004] In addition, due to the location of the embedded parts, the reinforced concrete wall is very thin and has a lot of steel bars, which can easily cause conflicts between the steel bars and the embedded parts, increasing the difficulty of construction.

[0005] Therefore, a new type of embedded connection node is needed to solve this problem. Utility Model Content

[0006] To address the construction difficulties caused by conflicts between reinforcing bars and embedded parts in shear walls, this utility model provides a connection node between a concrete component and a viscous damper embedded part. By adjusting the arrangement of reinforcing bars and using a special embedded part design, the problem of conflicts between reinforcing bars and embedded parts in shear walls is avoided.

[0007] This utility model provides the following technical solution: A connection node between a concrete component and a viscous damper embedded part is installed between beams of a building. It includes a concrete component part and an embedded connection part. The concrete component part includes a first concealed column longitudinal reinforcement, a second concealed column longitudinal reinforcement, a concealed column stirrup, a horizontal structural reinforcement, a vertical structural reinforcement, and a tie bar. The embedded connection part includes an end plate, a first steel plate, a second steel plate, a third steel plate, and a stud. The concrete hidden column stirrups are perpendicular to the longitudinal bars of the first and second concrete hidden columns and surround the longitudinal bars of the first and second concrete hidden columns; the concrete hidden column stirrups are arranged adjacent to the concrete horizontal structural reinforcement bars; the concrete horizontal structural reinforcement bars are arranged in a U-shape closed with the longitudinal bars of the first and second concrete hidden columns; the concrete vertical structural reinforcement bars are bent into a V-shape to surround the longitudinal bars of the first concrete hidden column, and the concrete tie bars are vertically tied to the concrete horizontal structural reinforcement bars at both ends. The first steel plate is welded to the second steel plate and the third steel plate, and the first steel plate, the second steel plate and the third steel plate are respectively welded to the end plate.

[0008] Furthermore, the longitudinal reinforcement bars of the first and second concealed concrete columns are bent in a U-shape to form a frame and anchored in the building beams, with an anchorage length of LAE.

[0009] Furthermore, the vertical structural reinforcement of the concrete is perpendicular to the horizontal structural reinforcement of the concrete.

[0010] Furthermore, the first steel plate and the third steel plate are respectively vertically welded to both ends of the second steel plate. The first steel plate and the third steel plate should be the same size and arranged in parallel.

[0011] Furthermore, the first steel plate, the second steel plate, and the third steel plate are perpendicular to the end plate and are connected by welding.

[0012] Furthermore, the first and third steel plates are symmetrically arranged with studs and connected by welding.

[0013] Furthermore, the spacing between the studs is 100mm, and there is at least one stud on each of the first and third steel plates.

[0014] Compared with the prior art, the beneficial effects of this utility model are: (1) By adjusting the arrangement of the reinforcing bars and adopting a door-shaped bend, this utility model effectively avoids the conflict between the reinforcing bars of the shear wall and the embedded parts.

[0015] (2) Compared with traditional anchor bar embedded parts, this utility model adopts a combination of steel studs, which can effectively improve the shear and bending resistance of the embedded parts. The studs can effectively improve the bond force between the embedded parts and the concrete, making it more reliable under the high-frequency reciprocating load of the viscous damper.

[0016] (3) This practical application has low construction difficulty, is easy to install and transport, can improve construction efficiency, and the shear bearing capacity of the embedded parts is greatly improved. Attached Figure Description
