Description

Anti-seismic building pile

Technical Field

The utility model belongs to the technical field of building antidetonation facility, specifically relate to an antidetonation building pile.

Background

With the occurrence of the earthquake in Tangshan and Wenchuan, the nation puts higher requirements on the earthquake resistance of buildings,

the building shock insulation support is a shock insulation device which is widely applied in the world and has mature technology. The vibration isolation device is placed on the base part or a certain position of a building to form a vibration isolation layer, the upper structure is separated from the lower base, so that seismic energy is isolated or dissipated, the transmission of the seismic energy to the upper structure is avoided or reduced, the safety of the upper structure and personnel and equipment inside the upper structure is effectively guaranteed, and the normal operation of indoor equipment is not influenced.

Compared with the traditional anti-seismic technology, the rubber shock insulation technology is safer, more reliable and more economical. The traditional anti-seismic technology is mainly characterized in that the anti-seismic technology is 'anti', the foundation and the foundation of a building are firmly connected together, the upper structure moves due to the occurrence of earthquake vibration, and when the bearing capacity of the material is exceeded, the decoration and internal equipment of the building are greatly damaged; the seismic isolation technology has the advantages that the upper structure is separated from the lower foundation by exerting the effect of 'isolation' by each town, the rigidity of a seismic isolation layer is small, the seismic reaction can be effectively reduced by 70-90%, the seismic intensity is reduced by 1-2 degrees, the construction cost is saved by 5-20%, the seismic isolation technology is widely applied to lifeline engineering, key construction projects and common house buildings, is widely applied to improvement and reinforcement of old buildings besides new construction, and is considered as a major leap of the seismic isolation technology: lead core, high damping and other shock absorption and isolation rubber supports and friction pendulum shock absorption and isolation supports appear in the market, and products are uneven;

in recent years, the environment protection is more and more emphasized and the punishment is more and more strict. The damping ratio of the lead core support is larger than that of the high-damping shock insulation rubber support, so that the seismic energy can be effectively reduced, but the lead core support has certain pollution to the environment due to the fact that heavy metal lead is contained in the lead core support. And the damping of the high-damping support is relatively small, and some earthquake working conditions cannot meet the design requirements. In recent two years, ultrahigh damping shock insulation rubber support products appear, the damping ratio of the high damping support is improved to a certain extent, but the rubber formula and the process are complex, the cost is high, the product quality is not easy to control, and the using amount is small.
