Earthquake-insulation construction process based on LRBLNR type support seat

Abstract

The invention discloses an earthquake-insulation construction process based on an LRBLNR type support seat. The earthquake-insulation construction process comprises the steps that (1), deepening design is performed according to the construction requirements; (2), lower buried plate assembling, hoisting and positioning are performed; (3), upper buried plate and support seat assembling, hoisting andinstalling are performed; (4), earthquake-insulation support seat circumferential sealing blocking is performed; and (5), bracket installing is performed. By means of the earthquake-insulation construction process based on the LRBLNR type support seat, the primary installation success rate of the earthquake-insulation support seat is improved, errors in the installation procedure are reduced, theconstruction schedule is greatly accelerated, the concrete compactness in casting is greatly improved, and construction quality control is conveniently performed, convenience is provided for follow-up construction, influence of high temperature or molten slag on the support seat in the upper-portion steel structure welding process can be prevented, deface caused to the support seat in the upper-portion structural concrete pouring process is avoided, and the situation that concrete intrudes into a connecting plate to influence later-period replacement of the support seat further can be prevented.

Description

technical field [0001] The invention relates to a technology for earthquake-isolation construction, in particular to an earthquake-isolation construction technology based on LRBLNR type bearings, and belongs to the technical field of building construction. Background technique [0002] Earthquake is an unavoidable natural disaster in human society, which will seriously affect people's normal life and economic operation, and cause serious economic losses. 90% or more of the casualties and economic losses caused by earthquakes are caused by the collapse of buildings. Therefore, it is very important to improve the anti-seismic fortification level and anti-seismic ability of construction projects. Since modern times, seismic isolation technology has been introduced into structural anti-seismic engineering and has achieved good results. Seismic isolation mainly uses isolation devices to prevent earthquakes from moving upward Transmission, to achieve the purpose of reducing struct...

[0002] Earthquake is an unavoidable natural disaster in human society, which will seriously affect people's normal life and economic operation, and cause serious economic losses. 90% or more of the casualties and economic losses caused by earthquakes are caused by the collapse of buildings. Therefore, it is very important to improve the anti-seismic fortification level and anti-seismic ability of construction projects. Since modern times, seismic isolation technology has been introduced into structural anti-seismic engineering and has achieved good results. Transmission, to achieve the purpose of reducing structural vibration, LRB / LNR type bearings are often used in building construction as a shock isolation device, in the existing technology, the concrete density poured when constructing LRB / LNR type bearings Not high, the construction quality is not easy to control, and the support is easy to be stained and damaged in the later construction, some poor construction technology makes it difficult to replace the later support, the construction efficiency is low, and the success rate is not high
