Hollow profile-shaped support component

摘要

The walling consists of a number of layers of paper. The layers comprise strips which are wound spiral fashion and overlap, and are connected by waterproof glue. The cross-section of the support component (1) is the same over its complete length. There is a woven layer, consisting of natural or artificial fibres between several layers of paper. The basic body of the support component is formed by a compound support (2) consisting of two basic bodies (4,5). The outer diameter of the smaller basic body corresponds to the inner diameter of the larger basic body. The one body is pushed coaxially inside the other and glued.
