Research And Application Of Low Cost Seismic Isolation Technology In Rural Buildings

Earthquake is a kind of destructive but unexpected natural disasters. Due to the rural areas are relatively backward economic development, a large number of serious shortage of the seismic resistance of rural self-built housing, when confronted with the earthquake hit, rural self-built housing, collapse of damage and the loss of casualties far above the city. So, how to improve the ability of rural areas self-built houses to resist earthquake damage has become a major topic of earthquake disasters field.This paper briefly analyzes the current isolation technology development present situation.Fairly effective seismic isolation technology as the current technology, the cost is higher, but the traditional isolation device to popularization and application in the village houses. So, research and development is economic and effective is suited for popularization and application of vibration isolation in villages and towns construction materials, equipment and technical measures has important practical significance.Based on the analysis, on the basis of investigation and research, in order to SBS modified asphalt isolation cushion isolation technology, pitch and mixed sand cushion isolation technology, gravel cushion isolation technology and sand cushion isolation technology as an example, discuss the analysis is given priority to with friction-sliding low cost of the basic principle of isolation technology and the technical method.Then in villages and towns monolayer house, for example, in view of the low cost of sand cushion and vibration isolation cushion is the SBS modified asphalt, analyzed by using two kinds of isolation measures after the isolation effect of the building.Analysis results show that using low cost in the villages and towns construction sand cushion and vibration isolation cushion is the SBS modified asphalt technology has a good damping effect. In this paper, combined with its isolation principle and the main factors of affecting the isolation effect, should be paid attention to in the construction of isolation layer is discussed the main problems, construction technology and technical measures.
