Fabricated frame structure damping reinforcing device and construction method thereof

Abstract

The invention relates to a fabricated frame structure damping reinforcing device and a construction method thereof. The fabricated frame structure damping reinforcing device comprises a first hinge seat, a second hinge seat, a first rod and a second rod; the first hinge seat and the second hinge seat are fixedly connected to a vertical column and a cross beam of a beam-column joint; the upper endof the first rod is hinged to the first hinge seat through a first hinge shaft, and a plurality of first radial through holes are formed in a rod body of the first rod in the axial direction at intervals; the lower end of the second rod is hinged to the second hinge seat through a second hinge shaft, and a rod body of the second rod is sleeved with the first rod; a plurality of second radial through holes which correspond to the multiple first radial through holes in a one-to-one mode are formed in the rod body of the second rod in the axial direction at intervals; and a positioning rod penetrates through the position between each first radial through hole and the corresponding second radial through hole. The energy dissipation and damping effects can be achieved through deformation energydissipation of the positioning rods and the hinge shafts, then only the positioning rods and the hinge shafts need to be replaced, the damping performance is good, the service life is long, construction is convenient, and mounting and dismounting are easy.

Description

Technical field: [0001] The invention relates to an assembled frame structure damping reinforcement device and a construction method thereof. Background technique: [0002] In recent years, my country has advocated the promotion of green and low-carbon prefabricated building structures, but the seismic performance of prefabricated concrete frame structures is often inferior to that of cast-in-place reinforced concrete frames. At the same time, prefabricated steel structures or steel-concrete composite structural frames also have seismic performance. Therefore, it is of great practical significance to carry out seismic reinforcement of frame structures. [0003] At present, arranging energy-dissipating and shock-absorbing devices in building structures to dissipate the energy input by earthquakes is a new technology to reduce earthquake response and earthquake damage. The existing energy-dissipating shock absorbers can be divided into two systems according to the different en...

Problems solved by technology

Metal damper: stable and reliable performance, not affected by temperature, simple structure, low cost, but difficult to control the threshold; friction damper: strong adaptability, can be widely promoted, but the expected friction coefficient will be affected by long-term static contact Changes; viscoelastic damper: excellent energy dissipation capacity, can work under large and small earthquakes, but greatly affected by ambient temperature, when the temperature rises, the energy dissipation capacity weakens; viscous damper: energy consumption Good performance, stable and reliable, provides additional damping but does not change the natural frequency, but the cost is high, the processing is difficult, and the viscous liquid is prone to leakage
