specific Embodiment approach 1

[0019] Specific implementation mode one: combine Figure 1 to Figure 3 To illustrate this embodiment, a post-earthquake repairable star-shaped beam end damper described in this embodiment includes two embedded parts 1 and a damping part;

[0020] The two embedded parts 1 are arranged opposite to each other, and are respectively fixed on both sides of the beam end and the bearing point or node at the beam end;

[0021] The damping element is layered between two embedded elements 1;

[0022] The damping parts include one-way hinges 2, ordinary bolts 3, connecting rods 4, friction-type high-strength bolts 5, core stable nodes 6, springs 7 and gaskets 8;

[0023] The core stable node 6 is arranged at the center between the two embedded parts 1 of the layer where the damping element is located, and the core stable node 6 is provided with a plurality of limbs; each limb of the core stable node 6 is connected with one end of the spring 7 respectively connected; gasket 8 is fixed on...

specific Embodiment approach 2

[0028] Specific embodiment 2: This embodiment further defines the post-earthquake repairable star-shaped beam end damper described in specific embodiment 1. In this embodiment, each layer of damping element is equipped with a one-way hinge 2. Simultaneously connect with one end of the two connecting rods 4 through the friction type high-strength bolt 5;

[0029] The gasket 8 that each layer of damping element is connected to the spring 7 is connected to the other end of the two connecting rods 4 at the same time, and the two connecting rods 4 that are simultaneously connected to the gasket 8 belong to two adjacent one-way Hinge 2. In this embodiment, on the premise of ensuring the rigidity of the connecting rod 4, the connecting rod 4 can adopt any length and cross-sectional form as required, and the end of the connecting rod 4 is widened to facilitate the bolt connection between the rods.

specific Embodiment approach 3

[0030] Specific implementation mode three: combination Figure 4 Describe this embodiment, this embodiment is to further define the post-earthquake repairable star-shaped beam end damper described in specific embodiment 1 or 2, in this embodiment, the one-way hinge 2 includes a fixed part 2-1 and connecting part 2-2;

[0031] The fixing part 2-1 is fixed on the embedded part 1;

[0032] One end of the connection part 2-2 is connected to the fixed part 2-1 by the ordinary bolt 3 as the rotation axis, wherein the direction in which the ordinary bolt 3 is arranged is perpendicular to the direction in which the friction-type high-strength bolt 5 is arranged, and the connection part 2- The other end of 2 is provided with connecting through hole.

[0033] In this embodiment, the fixing part 2 - 1 is arranged in parallel in the form of two blades, and one end of the connecting part 2 - 2 is arranged between the two blades, and is connected by a common bolt 3 in a shaft-connected ma...

Abstract

The invention discloses a post-earthquake-repairable star-like beam-end damper, and belongs to the technical field of building damping. For solving the problems that beam ends and joints of a frame structure in an earthquake are seriously damaged, and cannot be quickly repaired after the earthquake, two embedded parts are oppositely arranged, and are fixed to a beam end and the two sides of a beam-end bearing point or a joint respectively; a damping piece is arranged between the two embedded parts in layered mode; a core stable joint is arranged in the center of the two embedded parts, and isprovided with multiple branches; each branch is connected with a spring; gaskets are fixed at the ends of the springs; one-way hinging pieces are fixed on the embedded parts, and adopt common bolts asrotating shafts; one ends of connecting rods are in shaft connection with the one-way hinging pieces through friction-type high-strength bolts, and the other ends of the connecting rods are in shaftconnection with the gaskets through friction-type high-strength bolts. The post-earthquake-repairable star-like beam-end damper has multiple functions that post-earthquake deformation of a frame structure is reduced, earthquake energy is dissipated, and post-earthquake quick recovery is achieved, is flexible in arrangement and low in cost, and has good economy and practicability.

Description

technical field [0001] The invention belongs to the technical field of building shock absorption. Background technique [0002] Frequent earthquakes pose a serious threat to the safety of people's lives and property, and cause great damage and damage to various houses in the earthquake area; Concentrated at the beam ends and beam-column joints; due to the serious damage of the joints, the structure cannot be reused after the earthquake, so it has to be demolished forcibly; while causing great loss and waste, it also delays the recovery and reconstruction speed of the disaster area; and at this stage Two methods are mainly used to effectively protect beam ends and joints from damage caused by large earthquakes; first, to reinforce beam ends and joints. This method is simple and direct, easy to operate and understand, but due to the Uncertainty, it is difficult to accurately grasp the bearing capacity margin of beam ends and joints during design. While sacrificing economy, th...
