Abstract

A retainer clamp membrane fastening system is disclosed particularly adapted for retaining elastomeric membrane materials in position on a building roof. Various embodiments are described which may be attached to an upwardly projecting wall around the roof or which may be mounted directly to the roof perimeter. Each of the retainer clamp assemblies includes a core member which is fastened to the roof or wall surface. The core member has a pair of outwardly projecting arm portions. The membrane material is placed over the core member and a retainer clip is clipped over the membrane. The retainer clip includes leg sections having converging and diverging sections. The converging section conforms with the shape of a portion of the core member arms; the diverging sections engage with teeth of a clamping piece which fits over the entire assembly. The retainer clamp assembly according to this invention is inexpensive, attractive and reliable in preventing wind and water leakage of the roof.
