<p>PROBLEM TO BE SOLVED: To absorb fluctuation formed between a main piping buried in the underground and the main piping of a building so as to obtain good antiseismic performance by connecting and piping a flexible pipe having a prescribed length nearly in a right direction, connecting one end part of the piping to an underground buried piping, and connecting the other end to a feed piping of the building. SOLUTION: In the building 10 built by a base isolation construction method, a laminated rubber 12 is arranged between the building 10 and a ground foundation 11 so as to absorb vibration of the building. A main piping 13 for gas and feed/drain water piped in each floor of the building 10 is connected to an underground buried pipe 14 through an antiseismic piping 20 which is formed in such a constitution that two metal flexible pipings 21, 22 are connected by, for example, metal piping joint elbow 23, whose one end 24 is fixed to a ground side and connected to the underground buried piping 14, and whose the other end 25 is fixed to the building 10 side and connected to the piping 13 in the building. The pipe joint elbow 23 is mounted and fixed to a frame 30 installed a coma which is moved freely on its lower part.</p> |
