Title: Guide rail for applying plaster to wall - has T=shaped cross=section with small U=section fitted to web
Inventor: DRISCHLER ROLAND STEPHAN
IPC: E04F15/14
Filed: 1990-11-15
Abstract: The guide rail (1) is used when applying plaster to a wall in order to achieve a flat finished surface. When the plaster has hardened, the guide rail is removed and the gap is then filled with plaster to achieve a flush surface with the surrounding plaster. In order to reduce the volume of plaster to fill the gap left by the guide rail, the invention proposes using a T-section guide rail which is fixed to the wall by its flange. A U-section rail is fitted over the web of the T-section. After the applied plaster has hardened only this U-section rail is removed, thus leaving only a small gap to be filled with plaster.  This type of rail can also be used for laying concrete floors. USE - Applying plaster to walls in building.
