Description

A curved energy-dissipating connector

technical field

The energy-dissipating connector of the present invention can connect prefabricated components in prefabricated buildings and reduce the impact caused by small relative angles between components.

Background technique

The basic principle of shock absorption in engineering structures is to use special shock absorbing components or devices to make them enter the plastic state first under strong earthquakes to generate damping, thereby consuming the energy input into the building structure system, reducing the dynamic response of the structure, and better It is an effective, safe and economical engineering shock absorption technology to ensure the safety of the main structure. For this reason, technicians at home and abroad have developed and developed many types of damping devices.

There are two types of connections in prefabricated concrete structures: wet connections and dry connections. Dry connection is the connection of components by welding, bolting, post tensioning and pin connection. In the dry connection method, the stiffness of the joint is usually smaller than that of the component, and slippage occurs under a certain load value, and there is a weak part in the structure, so the deformation is mainly concentrated at the joint. The connecting member is then designed as a damper, making it an energy dissipating element inside the structure.

Generally, the relative displacement or rotation angle between the structural components of the building under the external force, earthquake or wind load is small, and the existing displacement-related energy dissipators need the structure to have a large relative deformation to fully To achieve the effect of energy consumption. At the same time, the existing energy-dissipating devices occupy a large space or require a more complex support system, which affects the space efficiency of the building and also affects the overall stiffness of the structure, so it is often limited in practical applications.

Contents of the invention

The purpose of the present invention is to develop a bending type energy-dissipating connecting element. On the one hand, in the prefabricated building structure, it can realize the connection between the bending deformation-based components without affecting the normal internal use and layout of the building. . On the other hand, the relatively small rotation angle caused by the external load (seismic action, etc.) can be amplified, and the energy dissipation capacity of the friction plate in the connector can be fully utilized to better realize the effective shock absorption of the building.
