Claims (1)

[Scope of Claim for Utility Model Registration] [1] Plate-shaped body 2 protruding in the radial direction of the tube 1,
A groove 3 formed in the longitudinal direction of the tube by the groove 3 and a rib 7 fitted into the groove 3 and integrally fixed to the plate-shaped bodies 2, 2 allow two or more tubes 1, 1 to move along the tube axis. A pipe composite structure for lightweight structural materials, characterized by being assembled and integrated in substantially parallel ways. [2] Scope of Claims for Utility Model Registration The pipe 1 described in item 1 is a resin-coated metal pipe in which the outer periphery of a thin-walled steel pipe 5 is coated with synthetic resin 6 in an even thickness and bonded, and the pipe 1 is a resin-coated metal pipe in which the outer periphery of a thin-walled steel pipe 5 is coated with a synthetic resin 6 in an even thickness and bonded. A pipe composite structure for a lightweight structural material, characterized in that the shaped body 2 is also formed integrally with the covering portion 6 made of the synthetic resin. [3] Scope of Claims for Utility Model Registration The pipe 1 described in item 1 is a resin-coated metal pipe in which the outer periphery of a thin-walled steel pipe 5 is coated with a synthetic resin 6 of equal thickness and bonded, and the ribs 7 are attached to the pipe 1. A pipe composite structure for a lightweight structural material, characterized in that it is integrally formed with the synthetic resin covering portion 6 as a plate-like body that projects in the radial direction of the pipe and is elongated in the pipe axis direction of the pipe. [4] Scope of claims for utility model registration, paragraph 2 or 3
A pipe composite structure for a lightweight structural material, characterized in that the plate-like bodies 2, 2 forming the grooves 3 and the ribs 7 described in 1. are bonded together with a synthetic resin adhesive. [5] Scope of claims for utility model registration, paragraph 2 or 3
The plate-shaped bodies 2, 2 and the ribs 7 forming the grooves 3 described in Section 1 are each provided as a pair for one tube 1, and are separated by an angle θ in the circumferential direction appropriate for the composite mode of the tubes. A pipe composite structure for lightweight structural materials, characterized by being formed in one piece. [6] It is noted that the rib 7 described in Claim 1 of the Utility Model Registration is independent from the pipe 1 and is formed as a plate-shaped body with a cross-sectional shape appropriate for the combination of pipes. Features: A pipe composite structure for lightweight structural materials.
