Construction method of rubber shock insulation support

Abstract

The invention relates to a construction method of a rubber shock insulation support. The method comprises the following construction processes of: constructing a cushion cap and a base plate; locating the position of the shock insulation support, measuring anchor bars and paying off, and binding lower support pier steel bars; pre-tightening a sleeve with high-tensile bolts, fixing the anchor bars, installing a steel pattern plate in a position same with the measured and located shock insulation support, and locating and fixing the steel pattern plate, the sleeve and the anchor bars; installing a lower support pier pattern plate, casting concrete, and aligning the concrete surface; removing the steel pattern plate, aligning the concrete surface, installing the shock insulation support, measuring the elevation and the horizontal position of the shock insulation support, and fastening with the high-tensile bolts and the sleeve; flatly laying a layer of asphalt felt which is cut and punched based on the same size of a shock insulation pad and the position of the sleeve on the upper surface of the shock insulation support; connecting upper embedded bars with the sleeve and fixing on the shock insulation support; setting a bottom pattern plate of an upper support pier; binding the upper support pier steel bars, and casting concrete after the examination and acceptance; and removing the pattern plates, and repairing and maintaining the paint of the shock insulation support.

Description

technical field [0001] The invention relates to a building shock isolation technology, in particular to a construction method of a rubber shock isolation bearing. Background technique [0002] Earthquake is one of the most serious natural disasters faced by human society. "Earthquake disaster mitigation" has become a worldwide concern, especially the "5.12" Wenchuan Earthquake, which caused a huge loss of property and people's lives. The research, development and application of seismic technology have brought great urgency and necessity. Rubber pad seismic isolation technology is a popular new engineering anti-seismic technology in the world. It places the vibration isolation and energy dissipation device (rubber vibration isolation pad) between the bottom of the structure and the foundation (or the top of the bottom column) to separate the upper structure and the foundation. "Separate". In this way, the dynamic characteristics and dynamic effects of the structure are chan...

Problems solved by technology

[0004] At present, there is no mature construction technology and construction method for the installation of rubber laminated seismic isolation bearings in China. Usually, the secondary grouting method is used or the pier concrete is poured twice; the secondary grouting method is to pour the concrete of the lower pier to the seismic isolation support. A height of 5cm is reserved under the seat, and the seismic isolation support is placed on the sleeve and fixed, and then the reserved 5cm is filled with high-strength grouting material; Well, reserve 200-400mm height for concrete pouring, and pour the reserved 200-400mm concrete again after installing the vibration isolation pad; this kind of construction is complicated and cumbersome, and the efficiency is not high
