A
Abstract:

PURPOSE: To provide a plastic-made hollow molded product which is thick in wall, long, free from residual stress, and suitable as a structural material of construction or the like in a park or the like.

CONSTITUTION: A false wood like hollow molded body of 10mm-50mm wall thickness (t) and at least 1m length (l) which is made of a waste plastic as a raw material, is used by filling a core material 2 in a hollow part 3. Since it is sufficiently cooled when molding, free from residual stress, and a vacant space of a specific width is provided between an inner wall surface of the hollow part 3 of the hollow molded body 1 and an outer wall surface of the core material, any crack is not generated even by expansion and contraction owing to fluctuation in atmospheric temperature.
