Metal casing for concrete surface draining gutter shell - uses threaded connections for adjustable fit

摘要

The galvanised metal bordering element for U-shaped drainage gutter shells made of cement or plastics bonded concrete, asbestos cement and plastics as used for surface drainage, is for insertion in a gutter base component which forms the gutter channel. At least one adjustable clamp connection for bordering element and gutter base component (11) is made by a threaded connection for the locking component (26). This connection may use dowel plugs (5a) in the sidewalls of the gutter base. The element provides firm connection between the gutter half shell and the casing element, and is adjustable for gutter coverings of different widths.
