Preshaped form

摘要

A system of prefabricated plaster relief forms are manufactured to be applied to prepared walls of a building, such as a home or other structure. The prefabricated forms are made of an open work lattice material formed into a channel shape having a top, two depending sides and outward directed flange portions. The lattice material is configured to receive and hold a cementitious material such as plaster. The top and the sides of the prefabricated forms are configured to present a protuberant contour projecting away from the flange sections and thereby outwardly from the prepared wall. The cross section and the ends of the prefabricated forms are shaped to align end-to-end with identically shaped forms. Alignment of a plurality of such forms in a longitudinal direction provides a continuous relief band along the wall of a structure. The prefabricated relief form flange sections are configured for attaching to the prepared walls by means of nails, screws or adhesive. An alternative prefabricated form member includes one or more guide members oriented in the longitudinal direction and spaced apart from the top and the sides. The guide member provides a guide edge for guiding a plastering tool along the length of the form while the form is being coated with plaster. Alternative angled prefabricated forms are provided for joining with adjacent longitudinal forms to create continuous relief bands around the corners of intersecting walls or the corners of door and window openings.
