Abstract
An anti-seismic beam-column joint of a single-layer assembly type cold storage structure comprises winged cow-leg pillars and precast concrete beams, wherein each precast concrete beam is arranged at the top end of the corresponding winged cow-leg pillar. The anti-seismic beam-column joint is characterized in that a high-damping seismic mitigation and absorption rubber support is arranged between the top end of each winged cow-leg pillar and the corresponding precast concrete beam; each high-damping seismic mitigation and absorption rubber support is of a structure that steel plates and rubber pieces are alternately overlapped to form a seismic insulation layer; a lead is arranged at the center of each seismic insulation layer, and each seismic insulation layer and the corresponding lead are fixed to the top end of the corresponding winged cow-leg pillar; the shape and the size of each seismic insulation layer are matched with the shape and the size of the top of the corresponding winged cow-leg pillar. According to the anti-seismic beam-column joint, the corresponding seismic insulation layer is arranged on the four-winged cow-leg pillar so that the seismic effect can be effectively isolated. Meanwhile, a TMD is formed between each precast concrete beam and the corresponding seismic insulation layer in the horizontal direction, and therefore stress and acceleration response of the cold storage structure under the seismic effect are beneficially reduced, safety of the cold storage structure under the seismic effect is ensured, and the earthquake fortification aims that the anti-seismic beam-column joint can not be damaged in the small earthquake, can be repaired in the medium earthquake and can not collapse in the large earthquake are achieved.
Description
Technical field
The utility model relates to a kind of antidetonation bean column node of individual layer panel-assembled cold store structure, is conducive to improve the anti-seismic performance of assembled integral individual layer freezer structure.Node horizontal direction adopts respectively prestressing steel wire bunch and rigid connector with the globality in raising face and outside face, and Seismic Isolation of Isolation Layer is set between beam column significantly to weaken earthquake motion effect.
