Novel supporting type metal damper

Abstract

The invention relates to the field of energy-dissipation components of building structures, in particular to a supporting type metal damper which is simple in mechanical property, convenient to mount and stable in energy dissipation. The novel supporting type metal damper comprises a connecting component and an energy dissipation component. The connecting component comprises a first connecting plate, a third connecting plate and a second connecting plate, wherein the first connecting plate, the third connecting plate and the second connecting plate are sequentially placed in parallel from top to bottom. The energy dissipation component comprises a first shearing energy-dissipation steel plate and a second shearing energy-dissipation steel plate, wherein the first shearing energy-dissipation steel plate is fixedly arranged between the lower plate surface of the first connecting plate and the upper plate surface of the third connecting plate, and the second shearing energy-dissipation steel plate is fixedly arranged between the lower plate surface of the third connecting plate and the upper plate surface of the second connecting plate. The supporting type metal damper is arranged between a beam and a column in an obliquely-supported mode, and hinge steel plates used for being connected with a beam-column frame of a building are arranged at the ends of the connecting plates correspondingly. The novel supporting type metal damper is simple in mechanical property, convenient to mount and stable in energy dissipation; and besides, the supporting type metal damper is simple and easy to transform, the construction period is short, and the apparent characteristics can be easily checked.

Description

technical field [0001] The invention relates to the field of energy-consuming components of building structures, in particular to a support type metal damper with simple mechanical properties, convenient installation and stable energy consumption. Background technique [0002] Earthquakes are known as one of the major natural disasters that threaten the safety of human life and property, and stronger earthquakes can cause damage to buildings. In the past, the traditional anti-seismic structural system often achieves the goal of consuming energy through the damage of the structure and load-bearing components, which will lead to different degrees of damage or even destruction of the structure after the earthquake. Structural energy dissipation and shock absorption technology is a new disaster prevention and anti-seismic technology. As a passive control measure, energy dissipation and shock absorption is to guide the seismic energy input into the structure to special mechanisms...

AI Technical Summary

Problems solved by technology

[0003] The traditional damper needs to pour mortar into the steel sleeve, which belongs to wet construction and requires a long construction period. There is a certain distance between the energy-dissipating steel plate and the inner filling mortar. The distance directly affects the ability of supporting plastic deformation to dissipate energy. However, scholars have obtained a more appropriate gap size based on research on some supports. Based on market demand, products have different requirements, and the gap size is not easy to optimize.
