Metal or plastic box rainwater gutter having a load-bering structure which is concealed from the outside

摘要

The aim of the abovementioned box-rainwater-gutter structure is to introduce a gutter of improved architectural design in addition to the hitherto conventional semicircular rainwater gutter without substantial extra costs. Furthermore, cutting down on the numerous gutter steel hangers - one on each rafter - also forms a basis for the invention.
