Description

Technical Field

[0001] The present invention relates to the technical field of earthquake prevention and disaster reduction, and more specifically, to a metal energy dissipation damper and an exchangeable energy dissipation connecting beam structure.

Background Art

[0002] In a seismic wall structure, two adjacent walls are connected by a connecting beam. Under the action of wind loads and earthquakes, in many cases, the internal force of the connecting beam is very large, resulting in large deformations, thereby absorbing a large amount of seismic energy and playing an important role in delaying the yielding of wall columns. The post-earthquake repair of conventional connecting beams has always been a difficult problem. In addition, when the connecting beam is damaged, serious damage occurs to the wall columns on both sides, resulting in large residual deformations in the structure, and the repair process is complex and time-consuming.

[0003] In recent years, researchers have proposed that by installing a metal damper in the center of the connecting beam, the main structure can be protected and seismic energy can be effectively dissipated. However, the metal damper still has problems to be solved, such as complex structure, difficult replacement, and heavy weight.

[0004] Therefore, how to provide an exchangeable damper structure with excellent energy dissipation effect is an urgent problem that those skilled in the art need to solve.

Summary of the Invention

Problems to be Solved by the Invention

[0005] In view of the above, the present invention provides a metal energy dissipation damper and an exchangeable energy dissipation connecting beam structure to solve the above technical problems.

Means for Solving the Problems

[0006] To achieve the above object, the present invention adopts the following technical solutions.

[0007] A metal energy dissipation damper, The damper energy dissipation section has connecting parts extending in opposite directions from the edges at both ends, and a non-adhesive slip layer is applied to both surfaces, The present invention includes a periphery-restraining steel plate that is provided around the outside of the damper energy dissipation section and has a gap between its inner wall and the outer wall of the damper energy dissipation section, wherein a flexible material is filled in the gap between the upper and lower edges of the damper energy dissipation section and the upper and lower inner walls of the periphery-restraining steel plate, and high-strength mortar is filled in the gap between the surfaces on both sides of the damper energy dissipation section and the inner walls on both sides of the periphery-restraining steel plate. Through the above technical solutions, the metal energy dissipation damper provided in the present invention consists of one energy dissipation section, a surrounding restraining steel plate, and a filling material. The upper and lower parts are filled with a flexible material, giving the damper energy dissipation section a certain deformation capacity in the vertical direction. The filling of both sides with high-strength mortar prevents the damper energy dissipation section from becoming unstable and bending. The structure is simple, and when relative displacement occurs in the vertical direction, the damper energy dissipation section deforms, thereby achieving energy dissipation.

[0008] Preferably, in the metal energy dissipation damper described above, the damper energy dissipation section is made of rectangular steel.

[0009] Preferably, in the metal energy dissipation damper described above, the connecting portion includes damper non-yield portions extending along both ends of the rectangular steel, the damper non-yield portions and the rectangular steel are formed by cutting the same steel plate, and damper end plates are perpendicularly welded to the edges of the opposite ends of the two damper non-yield portions.

[0010] Preferably, in the above-described metal energy dissipation damper, the non-yielding portion of the damper is an isosceles trapezoidal plate, the upper edge of the isosceles trapezoidal plate is docked to the end face edge of the rectangular steel section, and the lower edge of the isosceles trapezoidal plate is welded and fixed to the damper end plate. The shape of the isosceles trapezoidal plate is designed to prevent stress concentration.

[0011] Preferably, in the metal energy dissipation damper described above, a plurality of damper reinforcing ribs are provided at the welded portion of the isosceles trapezoidal plate to the damper end plate.

[0012] The present invention provides an interchangeable energy dissipation connecting beam structure comprising wall columns on both sides and connecting beam-shaped steel concrete sections provided continuously from the opposing inner walls of the wall columns on both sides, wherein a steel section is pre-embedded within the connecting beam-shaped steel concrete section, the ends of the steel section extend from the end faces of the connecting beam-shaped steel concrete section, and the ends exposed to the outside of the steel section are pre-fixed with embedded steel end plates, the metal energy dissipation dampers are connected between the two pre-embedded steel end plates, and the two connections are each connected to the two pre-embedded steel end plates via bolts.

[0013] With the above technical solutions, the energy dissipation damper provided in the present invention is connected to the main body structure via bolts, making removal and installation easy, allowing the energy dissipation component to be replaced, resulting in a lightweight design. The damper located in the center of the energy dissipation connecting beam has a small volume and a simple structure. When relative vertical displacement occurs in the connecting beam-shaped steel concrete sections on both sides, the damper energy dissipation component deforms, thereby achieving energy dissipation.

[0014] Preferably, in the above-described interchangeable energy dissipation connecting beam structure, the structural steel is an I-beam, the end of the I-beam that is separated from the pre-embedded structural steel end plate extends into the interior of the wall column, and connecting beam longitudinal ribs are welded and fixed to the surfaces of the upper and lower flange plates of the I-beam.

[0015] Preferably, in the above-described interchangeable energy dissipation connecting beam structure, there is a gap between the pre-embedded steel end plate and the corresponding end face of the connecting beam-shaped steel concrete section.

[0016] Preferably, in the above-described interchangeable energy dissipation connecting beam structure, corresponding screw holes for connecting the bolts are provided in both the pre-embedded steel end plate and the connecting portion.

[0017] Preferably, in the above-described replaceable energy dissipation connecting beam structure, the distance d between the upper inner wall and lower inner wall of the surrounding restraining steel plate and the upper and lower edges of the damper energy dissipation section is greater than the amount of shear deformation of the metal energy dissipation damper. [Effects of the Invention]

The energy dissipation damper can be replaced after an earthquake, and it is easy to operate and has excellent post-earthquake recovery capability. The structure is simple, and it is easy to manufacture and install. [Brief explanation of the drawing]
