Shock insulation groove system of novel house building foundation shock insulation structure

Abstract

The invention discloses a shock insulation groove system of a novel house building foundation shock insulation structure. The shock insulation groove system comprises a leakage-proof shock insulation groove formed between a shock insulation building body and a peripheral fixture, a shock insulation groove retaining wall, an underground outer wall, a reinforced concrete cushion layer at the bottom of the shock insulation groove, and a one-way compression laminated polystyrene foam filling body stuffed in the shock insulation groove, wherein the shock insulation groove retaining wall and the underground outer wall are arranged in the shock insulation groove. The shock insulation groove system has very high horizontal compression performance and necessary vertical strength and rigidity, so that the seismic isolation groove system can freely move in the horizontal direction under the action of an earthquake and can vertically meet the requirement for passing of personnel. The shock insulation groove system has the advantages that the industrialization degree is high, mounting and construction are easy, misoperation of constructors is reduced, the construction speed is increased, it is guaranteed that the upper structure of the shock insulation building body and a peripheral site fixture 2 can freely deform, and the shock insulation efficiency of the shock insulation structure is improved.

Description

technical field [0001] The invention relates to the field of building foundation shock-isolation engineering, in particular to a novel shock-isolation ditch system for building foundation shock-isolation structures. Background technique [0002] As a natural disaster, earthquake has caused huge disasters to human beings many times in history. In recent years, with the continuous deepening of the research on shock absorption and isolation technology for construction engineering, engineering application work has been carried out in some high-seismic areas in my country. The safety of people's life and property has produced good social benefits. Practice has proved that shock absorption and isolation technology can effectively reduce the effect of earthquakes and improve the anti-seismic fortification capacity of building construction projects. [0003] Base isolation is one of the earlier researched, more mature and widely used technologies in the seismic isolation technology...

AI Technical Summary

Problems solved by technology

The cast-in-place cantilever type seismic isolation ditch cover has the following defects: (1) Although measures such as smooth surface and graphite powder coating are required in the design, there is often a gap between the movable prefabricated concrete slab and the concrete base due to reasons such as construction and later maintenance. Excessive friction hinders the large deformation of the seismic-isolation building theme under rare earthquakes; (2) During the building surface and water-spray construction, the construction personnel misunderstand the design or pay insufficient attention to the seismic-isolation structure, It is easy to cause the cover plate of the seismic isolation trench, the movable precast concrete slab and the upper building surface of the ramp (step) to be poured into one by mistake, which affects the free movement of the upper structure; (3) the gap of the horizontal seismic isolation joint is very small, and the construction The accuracy is difficult to control, and the construction error will easily cause the gap between the cover plate of the isolation ditch and the retaining wall of the isolation ditch to not slide freely, which will greatly limit the isolation efficiency of the isolation structure when an earthquake occurs, and even cause damage; (4 ) Once the cantilevered seismic isolation ditch cover plate is damaged, it is difficult to repair; (5) The seismic isolation structure measures are concealed projects, and the site signs are not obvious
