Title: HOLLOW PLASTIC SECTION
Abstract:
The invention relates to a hollow plastic section, comprising embedded reinforcing elements. Said hollow plastic section is preferably configured as a frame section for windows or doors. According to the invention, the section has several inner chambers which are delimited by separating walls (7, 8, 9, 14, 15, 16, 17, 18) that extend in the longitudinal direction of the section. Strip-shaped stiffening elements (4, 5, 11, 12, 25) that are not interconnected are used as reinforcing elements. The reinforcing elements can consist of either a metal or embedded bands or strips consisting of fiber-reinforced plastic. Several inner chambers with a small cross-section that are delimited by separating walls (7, 8, 9, 14, 15, 16, 17, 18) extending in the longitudinal direction of the section are provided.
