Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of energy dissipation viscous damping wall, and particularly relates to a ring-shaped sliding groove connecting device for releasing out-of-plane constraint of viscous damping wall. BACKGROUND
[0002] The viscous damping wall is a damper which can be installed between structural layers as a wall body, and is a speed-dependent damper which utilizes the relative movement between structural layers to play the energy dissipation role of the viscous damping wall. The traditional viscous damping wall is composed of an inserted steel plate, an outer steel plate and an internal high-viscosity damping medium, and the mechanical energy of the structure is converted into heat energy dissipation through the movement of the inserted steel plate in the high-viscosity damping medium.
[0003] The viscous damping wall has been widely used in the field of buildings to meet the seismic requirements of buildings, but the influence of the damping wall under multidimensional earthquakes is not considered. In the past earthquakes, the viscous damping wall is prone to buckling at the connection, thereby causing the damping wall to be unstable and damaged, and losing the role of energy dissipation and seismic reduction under earthquakes. The reason is that the traditional viscous damping wall only considers the in-plane seismic reduction of the damping wall, and does not consider that the out-of-plane force under multidimensional earthquakes acting on the connection of the damping wall will cause the connection to buckle. SUMMARY
[0004] The purpose of the present application is to overcome at least one of the defects of the prior art and provide a ring-shaped sliding groove connecting device for releasing the out-of-plane constraint of the viscous damping wall.
[0005] The inventor believes that the out-of-plane force cannot be ignored in the design of the viscous damping wall, and in the present application, the inventor releases the out-of-plane force by designing a ring-shaped sliding groove connecting device to reduce the risk of instability and damage of the damping wall under multidimensional earthquakes.
[0006] The purpose of the present application can be achieved by the following technical solutions:
[0007] A ring-shaped sliding groove connecting device for releasing the out-of-plane constraint of the viscous damping wall is installed between the upper beam and the damping wall, and comprises a ring-shaped track and an extended universal ball structure.
[0008] The extended universal ball structure comprises a metal rod; the outer end of the upper end surface of the metal rod penetrates into the side of the ring-shaped track;
[0009] The upper end surface of the ring-shaped track is fixedly connected with the upper pier provided on the upper beam;
[0010] The lower end surface of the metal rod is fixedly connected with the supporting member provided in the damping wall. The supporting member comprises a steel plate inserted in the damping wall, and an upper connecting plate provided on the upper end surface of the steel plate, and the lower end surface of the metal rod is fixedly connected with the upper end surface of the upper connecting plate.
[0011] More specifically, the two annular tracks in the application are symmetrically arranged, and the metal rod is located between the two annular tracks, and the two ends of the metal rod extending outward from the upper end are respectively inserted into the sides of the annular tracks.
[0012] Further, the lower bottom surface of the end of the metal rod located in the annular track is provided with a first universal ball; and the end face of the end is provided with a flexible material layer and a metal sheet from inside to outside. Specifically, the flexible material layer is attached to the end face of the end of the metal rod at both ends, and a metal sheet is additionally attached to the outside of the flexible material layer. The flexible material layer can reduce the damage to the metal rod when the damping wall is in action.
[0013] Further, the first universal ball is connected to the lower bottom surface of the end of the metal rod located in the annular track by a bolt.
[0014] Further, the annular track comprises an annular box body and a top connecting column nested and connected with the upper end surface of the annular box body; a plurality of metal spheres abutting each other are arranged in the annular box body; and the upper end surface of the top connecting column is fixedly connected with the upper pier. Specifically, the annular box body is connected by the top connecting column, and the metal spheres are filled in the annular box body and abut against each other.
[0015] Further, the upper end surface of the top connecting column is fixedly connected with the upper pier by a bolt.
[0016] Further, after the first universal ball enters the annular track, the metal spheres abutting each other fill the remaining track plane of the annular track. Specifically, the metal spheres can fill the remaining track plane of the annular track after the universal ball enters the annular track; when the universal ball rolls back and forth in the straight box body, the metal spheres periodically move clockwise and counterclockwise under the pushing of the universal ball; at the same time, the metal spheres can also produce certain constraint effect on the movement of the metal rod out of the plane.
[0017] Further, a lubricant is added between the metal spheres abutting each other.
[0018] Further, the annular box body is divided into a straight box body section and a curved box body section connected in series; and the straight box body section and the curved box body section connected in series form a closed track.
[0019] The straight box body section is perpendicular to the plane of the damping wall, and the midpoint is located on the plane of the damping wall and close to the side of the extended universal ball structure.
[0020] The second universal ball is arranged on the inner side wall of the straight box section and is in contact with the metal sheet at the end face of the end of the metal rod in the annular track, the contact between the second universal ball on the inner side wall of the straight box and the metal sheet can reduce the friction force when the extension universal ball structure moves out of the plane, and the out-of-plane force can be better released.
[0021] Further, the diameter of the second universal ball is much smaller than that of the first universal ball.
[0022] Further, a rectangular hole is arranged on the outer side wall of the straight box section, the length of the rectangular hole is not less than the length of the track of the reciprocating movement of the first universal ball in the direction, and the width is not greater than the diameter of the metal ball. The extension universal ball structure can extend the end of the rod into the annular track through the rectangular hole, so that the universal ball rolls in the straight box.
[0023] Further, the straight box section and the curved box section are connected by welding.
[0024] Compared with the prior art, the present application has the following beneficial effects:
[0025] (1) The extension universal ball structure and the annular track are used to separate the connecting structure of the traditional viscous damping wall into two independent devices that can move freely in the direction perpendicular to the plane of the damping wall, which releases the out-of-plane force and effectively avoids the damage of the connecting structure of the damping wall and the instability of the damper.
[0026] (2) The annular track and the metal ball are designed to constrain and release the movement of the damping wall in different directions, ensuring that the working performance of the viscous damping wall in the energy dissipation direction is not affected under complex bidirectional forces, thereby improving the reliability of the viscous damping wall under out-of-plane forces.
