Abstract
A method of connecting pipes for pipelines in a multistoried building and a flanged pipe joint used therein. The method comprises making a through-hole in a wall or floor portion of the building through which pipes are connected, the through-hole being larger in diameter than the pipes to be connected; providing a pair of anchor bolts in the building portion on both sides of the through-hole; covering the through-hole via an elastic gasket with a pipe joint provided with a flange having a pair of collars oppositely projecting therefrom; connecting the pipe joint with the pipes to be connected; and securing the collars to the building portion by the anchor bolts to seal the through-hole so as to prevent leakage of fluid therefrom. The pipe joint has a central bore at one end to receive one of the pipes to be connected via an elastic packing, another central bore at the other end to receive the other pipe and a flange to be secured to the building portion via an elastic packing in an air-tight manner to seal the through-hole.
