Description

Technical Field

[0001] The utility model relates to the field of shock-absorbing and energy-consuming structural parts, in particular to an axial energy-consuming rotating rod damper. Background Art

[0002] Traditional buildings mainly rely on the deformation of their own structures to absorb earthquake energy. Many main components are difficult to repair after being damaged. Structural earthquake resistance has gradually shifted from anti-collapse design to recoverable functional design, in order to minimize the losses to the entire society after the earthquake.

[0003] At present, metal dampers are usually used in various types of building structures. Their working principle is usually to increase their energy dissipation and shock absorption capabilities by increasing relative displacement. Publication No. CN219548547U discloses an axial tension-compression corrugated soft steel plate energy dissipation damper, which uses corrugated energy dissipation soft steel as the core energy dissipation element. The corrugated energy dissipation soft steel will produce a small accordion effect during the deformation process, and has a strong energy dissipation capacity. During the deformation and energy dissipation process of the corrugated energy dissipation soft steel, the upper and lower flange plates will produce bending deformation energy dissipation to reduce the damage of the external tensile and compressive stress to the shear wall structure. However, the energy dissipation structure in this structure is single, and the damper is subjected to tensile and compressive stresses, and it does not involve how to dissipate the reciprocating horizontal external force generated during an earthquake.

DETAILED DESCRIPTION

[0032] The present invention will be further described in detail below in conjunction with specific embodiments, which are intended to explain the present invention rather than to limit it.

The inner sides of the first horizontal convex plate 2-1 and the second horizontal convex plate are provided with mounting holes, and the two ends of the vertical rotating tube 2-8 are provided with integrally formed round tables to cooperate with the mounting holes.

[0034] The second vertical arc plate 2-3 is fixed to the other side of the mounting seat, and the vertical rotating tube 2-8 is rotatably arranged between the first horizontal convex plate 2-1 and the second horizontal convex plate.

[0035] The inner side of the first vertical arc plate 2-4 and the inner side of the second vertical arc plate 2-3 are both provided with arc-shaped long grooves, and the rotating roller 3-2 slides along the arc-shaped long grooves. A serrated friction rubber strip is provided in the arc-shaped long grooves. The purpose of the serrated friction rubber strip is to increase the roughness of the contact surface. The serrated rubber 2-7 increases the friction of the pulley sliding to achieve energy consumption. During the rotation of the rotating rod 3-1, further energy consumption is achieved by the friction between the rotating roller 3-2 and the serrated rubber 2-7.

[0036] Reference Figure 1 , 5 6. The rotating rod 3-1 is provided with a reset spring 3-4 on both sides along its rotating plane. The reset spring 3-4 is connected to a mounting seat at one end away from the rotating rod 3-1. When installed, the reset springs 3-4 on both sides of the rotating rod 3-1 are in an extended state. In order to facilitate the installation of the reset spring 3-4, a vertical connecting plate 2-5 is provided between the first horizontal convex plate 2-1 and the second horizontal convex plate for support. One end of the reset spring 3-4 is connected to the rotating rod 3-1, and the other end is connected to the vertical connecting plate 2-5. The vertical connecting plate 2-5 also plays a supporting role and forms a mounting seat together with the first horizontal convex plate 2-1 and the second horizontal convex plate. The first horizontal convex plate 2-1, the second horizontal convex plate and the vertical connecting plate 2-5 can be connected by bolts, or by welding or other methods.

[0037] The first end plate 1-1 is disposed outside the first vertical arc plate 2-4, and the second end plate 1-2 is disposed outside the second vertical arc plate 2-3. The first end plate 1-1 and the second end plate 1-2 are used to connect to the outside. In this embodiment, the first end plate 1-1 and the second end plate 1-2 are connected by welding, or other detachable fixed connection methods.

[0038] Reference Figure 1 , 6 The corner of the first end plate 1-1 on the side away from the first vertical arc plate 2-4 and the corner of the second end plate 1-2 on the side away from the second vertical arc plate 2-3 are both provided with stiffening structures; four stiffening structures are provided on the first end plate 1-1, which are respectively arranged on the upper and lower sides of the two corners of the first end plate 1-1, and the two stiffening structures on the same side are symmetrically arranged, and the two vertical stiffening structures are fixed by connecting bolts 1-5; the stiffening structure on the second end plate 1-2 has the same arrangement and connection method as the stiffening structure on the first end plate 1-1.

The bottoms of the first vertical stiffening plate 1-4 and the second vertical stiffening plate are connected to the first end plate 1-1. The horizontal stiffening plate 1-3 is horizontally arranged with the first end plate 1-1, and is connected to the tops of the first vertical stiffening plate 1-4 and the second vertical stiffening plate.

[0040] The installation steps of an axial energy dissipation rotating rod damper of the utility model are as follows:

[0041] First, connect the connecting bolts 1-5 to the external structure with bolts, and then connect the connecting bolts 1-5 to the horizontal stiffening plate 1-3; then weld the horizontal stiffening plate 1-3 to the vertical stiffening plate, and fix them to the first end plate 1-1 and the second end plate 1-2 by welding; the first end plate 1-1 and the second end plate 1-2 are welded to the first vertical arc plate 2-4 and the second vertical arc plate 2-3 respectively; the first horizontal convex plate 2-1 and the second horizontal convex plate are welded to the second vertical arc plate 2-3 by welding.

[0042] A rotatable vertical rotating tube 2-8 is installed at the center of the first horizontal convex plate 2-1 and the second horizontal convex plate to ensure that the vertical rotating tube 2-8 can rotate and cannot be horizontally displaced; the central parts of the upper and lower rotating rods 3-1 pass through the vertical rotating tube 2-8, and rotating rollers 3-2 are respectively installed at both ends of the rotating rod 3-1, and then a reset spring 3-4 is welded on both sides of the rotating rod 3-1, and the other end of the reset spring 3-4 is welded to the vertical connecting plate 2-5; rubber strips are placed on the inner sides of the first vertical arc plate 2-4 and the second vertical arc plate 2-3, and then the first vertical arc plate 2-4 and the second vertical arc plate 2-3 are connected by welding to realize the connection of the corrugated connecting piece 2-6.

[0043] When an earthquake occurs, the rotating rod 3-1 is arranged in two layers, and energy is consumed by friction between the rotating roller 3-2 and the serrated rubber 2-7. After the damper is compressed and deformed, it is reset by the reset spring 3-4, and friction energy is consumed while the damper is tensilely deformed. The first vertical arc plate 2-4 is connected to the first horizontal convex plate 2-1 and the second horizontal convex plate by four corrugated connecting plates 2-6. During the tension and compression process of the damper, the corrugated plate is deformed by tension and compression to form an accordion effect, thereby realizing energy consumption.

[0044] When the damper receives the horizontal force transmitted by the earthquake, the vertical rotating tube 2-8 will produce left and right reciprocating motion in the horizontal direction, and the vertical rotating tube 2-8 will drive the rotating rod 3-1 to reciprocate, and the rotating rod 3-1 will rotate with the vertical rotating tube 2-8 as the axis due to the restriction of the return springs 3-4 on both sides, so as to achieve the dissipation of the horizontal energy of the earthquake. When the damper is tensilely deformed, friction energy is consumed at the same time. The first vertical arc plate 2-4 is connected with the first horizontal convex plate 2-1 and the second horizontal convex plate by four corrugated connecting plates 2-6. During the tension and compression process of the damper, the corrugated plate is tensilely deformed to form an accordion effect, thereby achieving energy dissipation.
