Composite material polyurethane rigid foam decorative marble pillar

Abstract

A composite material polyurethane rigid foam decoration Roman column, includes: a column shell, which has an inner space is defined by the column shell closed rounding, wherein, the column shell comprises a column basis part, a column body part provided on the column basis part; and a column cap part provided on the column body part; and an inner layer, the material of which is PU, closely joints on the inner surface of the column shell, which is combined with the column shell to form a composite material to strengthen the support strength and the resistance of the column shell.

Description
