To attain the shortening of construction term, efficiency improvement, industrialization and the unnecessitating of fastening tool, to decrease the amount of waste materials at the job site of construction and to facilitate the construction at the job site by providing the terminal part of piping, which appears on the outer surface of a planar material, with bonding joint for pushing in and bonding the joint of an external piping terminal part.

A construction panel 10 for piping is provided with an almost cylindrical bonding joint fixer 60 fixed on its planar material 21 and a bonding joint 40. The bonding joint 40 is fixed into the bonding joint fixer 60 at the upper end part of piping 30 and the joint at the terminal part of piping 30 is pushed in and bonded. Before the construction, first of all, the bonding joint 40 is screwed and fixed into one terminal part of fixed piping 32 at a factory and fixed through a fixture nut 56 to a bottom part 64 of the bonding joint fixer 60. Thus, the fixed piping 32, bonding joint fixer 60 and bonding joint 40 are integrated and fixed through nails 61 onto the planar material 21 of the construction panel 10 for piping. Since it is enough only to convey such an integrated object to the job site and to construct it, labor for conveyance is simplified and job site management is facilitated as well.
