Problems solved by technology

After the limit device is installed in the earthquake-isolated house, when an earthquake occurs, the house will not experience excessive displacement during the sliding process of the earthquake-isolation layer. Displacement, even damaged and collapsed, did not achieve the proper shock isolation effect

Abstract

The invention relates to a base isolation limiting device and a manufacturing method, and belongs to the technical field of building structure earthquake resistance. The device comprises a circular limiting steel plate, a lower nut, a limiting screw rod and an upper nut. When a lower foundation beam of a house is manufactured, a section of steel pipe is embedded, a hole is reserved below the steel pipe, the lower nut is welded to the circular limiting steel plate and placed into the hole of the lower foundation beam, and then the limiting screw rod is inserted into the steel pipe and connected to the lower nut. The two sides of the hole are plugged with concrete plug blocks, fine sand is poured into the steel pipe from an upper opening, and the steel pipe and the hole are filled with the fine sand. The lower foundation beam is paved with a base isolation layer, an upper foundation beam is cast on the base isolation layer, the limiting screw rod penetrates through the base isolation layer, a part of the limiting screw rod is cast into the upper foundation beam, the top end of the limiting screw rod extends out of the upper foundation beam, and then the upper nut is screwed. The base isolation limiting device has the advantages of being economical, reasonable, convenient to construct, good in limiting effect and the like.

Description

technical field [0001] The present invention relates to a base shock-isolation limiting device and a manufacturing method thereof, which are applied to low-rise masonry houses in villages and towns provided with a shock-isolation layer. . Background technique [0002] my country is an earthquake-prone country. In recent years, the Wenchuan earthquake and Yushu earthquake have caused huge casualties and property losses. my country's earthquake areas are widely distributed, and the areas with fortification intensity of 6 degrees and above account for more than 60% of the country's land area, and are mainly distributed in the vast rural and township areas. Due to the limitation of economic capacity in the vast rural areas and towns, the anti-seismic ability of villages and towns is poor. When subjected to the same earthquake intensity, the degree of collapse and damage of rural buildings and the number of casualties are much higher than those in cities, and the earthquake disa...
