(57) [summary] (modified with) [purpose] is assembled using a resin-coated steel pipe as a structural material, and a stray di rack and cultivation for the House other so-called lightweight structural materials, especially load bearing, rigidity is exceptional large strut Toka beams, to provide a joint member of lightweight structural resin-coated steel pipe, which is used to make such digit. [Configuration] outer peripheral surface and the same shape of the resin-coated steel pipe, concave 1 of the university There are formed at least two sides in the longitudinal direction, the concave surface 1 and is formed in the skin layer of a low foaming surface, the interior is 1.5 to. Is a foamed molded article having an 8-fold expansion ratio, the concave one Two or more resin-coated steel pipe by which the resin-coated steel pipe is to be melted and joined in abutment by a solvent type adhesive liquid is combined substantially parallel to the tube axis.
