TECHNICAL FIELD
[0001] The present application relates to the technical field of energy dissipation viscous damping wall, and particularly relates to a straight chute 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, is a speed-dependent damper, and utilizes relative movement between structural layers to play a role of energy dissipation of the viscous damping wall. The traditional viscous damping wall is composed of an inserted steel plate, an outer steel plate and internal high-viscosity damping medium, and mechanical energy of a structure is converted into heat energy dissipation through 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 previous earthquakes, the viscous damping wall is prone to buckling at the connection, thereby causing instability and damage of the damping wall and losing the role of energy dissipation and seismic mitigation under earthquakes. The reason is that the traditional viscous damping wall only considers in-plane seismic mitigation of the damping wall, and does not consider that when out-of-plane forces under multidimensional earthquakes act on the connection of the damping wall, buckling occurs at the connection. SUMMARY
[0004] The purpose of the present application is to overcome at least one of the defects of the prior art and provide a straight chute connecting device for releasing out-of-plane constraint of 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 through the designed straight chute connecting device to reduce the risk of instability and damage of the damping wall under multidimensional earthquakes.
[0006] Under multidimensional earthquakes, the main displacement direction of the viscous damping wall normally works, and the force is conducted to the upper layer through the rib plate; in the direction perpendicular to the plane of the damping wall, the damping wall freely slides on the sliding box through the sliding block to release the out-of-plane force.
[0007] The purpose of the present application can be achieved by the following technical solutions:
[0008] A straight chute connecting device for releasing out-of-plane constraint of viscous damping wall is installed between an upper beam and a damping wall, and comprises:
[0009] The sliding block is in the shape of a V, and the inner concave side is connected to the end of a support member provided on the upper end face of the damping wall; the support member comprises a steel plate inserted into the damping wall and an upper connecting plate provided on the upper end face of the steel plate, and the inner concave side of the sliding block is connected to the end of the upper connecting plate;
[0010] The sliding block is located in the sliding box body and in frictional contact with the sliding box body, and the upper end surface of the sliding box body is fixedly connected with the upper abutment provided on the lower end surface of the upper beam.
[0011] The rib plate is provided on the outer lateral wall of the sliding box body.
[0012] The sliding block and the sliding box body are one-to-one corresponding, two in number, and symmetrically arranged at the two ends of the upper connecting plate.
[0013] Further, the sliding block comprises an extension block in the shape of a V, and a first universal ball provided on the lateral wall of the extension block. Specifically, the sliding block is connected to the main body of the damping wall. The first universal ball is installed on the extension block (which can reduce the resistance generated by the frictional contact between the sliding block and the top plate and the bottom plate when sliding, and prevent structural damage due to friction.
[0014] Further, the first universal ball has an even number of balls, and is symmetrically arranged on the upper and lower end surfaces of the extension block in contact with the inner wall of the sliding box body. Preferably, the first universal ball has four balls.
[0015] Further, the sliding box body is surrounded by a bottom plate, two folding plates, a top plate, and a universal ball plate;
[0016] The folding plate is an L-shaped plate, which is divided into a first handle end and a second handle end, the first handle end is connected with the top plate, and the second handle end serves as the inner wall of the box body;
[0017] The folding plates are symmetrically arranged, and the bottom plate is clamped between the symmetrically arranged second handle ends; the lower end surface of the top plate is fixedly connected with the end surface of the outer convex side of the first handle end;
[0018] The universal ball plate is embedded in the area surrounded by the bottom plate, the two folding plates, and the top plate;
[0019] The upper end surface of the top plate is fixedly connected with the upper abutment.
[0020] Further, the bottom plate, the two folding plates, the top plate, and the universal ball plate that abut each other are fixed by welding.
[0021] Further, the end surface of the outer convex side of the second handle end of the folding plate is provided with a flexible material layer.
[0022] Specifically, the bottom plate, the folding plate, the top plate, and the universal ball plate should surround a box body with one side open, the opening facing the direction of the damping wall, so that the sliding block can slide inside the surrounded open box body, and the flexible material layer is attached to the inner side of the box body to reduce damage to the connecting device caused by sliding impact.
[0023] Further, the first handle end of the top plate and the folded plate abut each other, and a threaded hole corresponding in size and position is preformed at the abutted region of the two; the threaded hole is used for threaded connection of the straight chute connecting device and the upper pier. Specifically, the bolt can be directly fixed through the threaded holes on the folded plate and the top plate and the upper pier, so as to realize the fixed connection between the straight chute connecting device and the upper pier.
[0024] Further, the universal ball plate comprises a connecting plate and a plurality of second universal balls arranged in a matrix on the end face of the connecting plate; the second universal balls are located in the sliding box body. The second universal balls are fixed on the connecting plate by bolts. The second universal balls cover the entire connecting plate surface of the connecting plate, so as to reduce the friction resistance of the sliding block when sliding on the connecting plate surface.
[0025] Further, the rib plate is welded to the area surrounded by the top plate and the universal ball plate. Specifically, the rib plate is welded and fixed with the universal ball plate and the top plate, so as to increase the rigidity of the sliding box body, so that when the universal ball plate is subjected to compressive stress in the main displacement direction of the damping wall, the force transmission can be supported, and the in-plane structural strength is increased.
[0026] Further, the first universal ball is in frictional contact with the bottom plate and the top plate, and the convex surface of the extension block is in frictional contact with the universal ball plate, so that the sliding block can slide in the sliding box body. Specifically, the first universal ball is in frictional contact with the bottom plate and the top plate, and the side surface of the extension block is in frictional contact with the universal ball plate, so that the sliding block can be constrained in the sliding box body and only slide in the direction perpendicular to the plane of the damping wall.
[0027] Compared with the prior art, the present application has the following beneficial effects:
[0028] (1) In the present application, the upper viscous damping wall is not directly connected with the upper main beam, but is connected with the sliding block and the sliding box body which are two relatively independent structures. By the back and forth movement of the sliding block on the sliding box body, the out-of-plane force acting on the damping wall is released at this position, effectively avoiding the damage of the structure and the instability of the damper caused by the out-of-plane force acting on the connection of the damping wall.
[0029] (2) The present application does not affect the energy dissipation and shock absorption in the main displacement direction of the damping wall, and improves the reliability of the viscous damping wall under the out-of-plane force. BRIEF DESCRIPTION OF DRAWINGS
