Initialization pipe arrangement construction method and initialization pipe arrangement component null of flexibility tube from inside

摘要

PURPOSE: To do a construction work easily at low cost by a method wherein a part of a flexible pipe in a slab that is coming out to outside the slab is covered with a piping member which is constituted of a flexible pipe and the flexible pipe is so positioned that one end of the piping member may be inside the slab and the other end outside the slab. CONSTITUTION: A reinforcing steel member 19 and a frame 33 are assembled to form a slab 21 and then a flexible pipe 11 is lain in the assembly. An end of the flexible pipe 11 is raised aslant to come above a slab surface 21. The end of the flexible pipe 11 is covered with a rising piping member 27 which is formed from a foam polyethylene pipe and is fixed to the reinforcing steel member 19 with a wire. The piping member 27 is so positioned that its one end may be inside the slab and the other end may be outside the slab. Concrete is placed inside the frame 33 and is hardened and thereby the slab 21 is formed. Part of the piping member 27 which comes outside the slab surface 21a is cut off. As an opening of the slab surface 21a is nearly oval, the position of the flexible pipe can be arranged, By this method, a piping work can be simplified and the performed at low cost.
