Abstract
The invention relates to a light-weight concrete construction panel having a layer of reinforcing mesh bonded to each of the two faces. Such panels are used on walls and floors as backerboards for the installation of ceramic tile and other facing materials. In this invention the web of mesh or other fabric wraps around the edge of the panel and is bonded in place on the top and bottom faces. The strip of mesh covering the edge is left unbonded and open; when two panels are placed abutting each other the unbonded strip of mesh along the edge captures the mortar that is applied to fill the joint. This permits improved edge-to-edge bonding.
Claims10
A fabric reinforced cementitious construction panel comprising a cementitious core layer and a layer of pervious reinforcing fabric covering each of the two faces of said core layer, said fabric also wrapping at least one of the two longitudinal edges of said panel, said fabric being bonded to each of said two core faces and being unbonded along said wrapped longitudinal edge of said panel.
A fabric reinforced cementitious panel consisting of a core layer comprising light-weight aggregate and cementitious material and a layer of pervious reinforcing fabric bonded to each of the two faces of said core layer with cementitious material, at least one of the longitudinal edges of said panel being wrapped with said reinforcing fabric, said reinforcing fabric being open and substantially free of said cementitious material along said panel edge.
A fabric reinforced cementitious panel consisting of a core layer comprising light-weight aggregate and cementitious material and a layer of pervious reinforcing fabric covering each of the two faces of said core layer, said fabric also wrapping at least one of the two longitudinal edges of said core layer, said fabric being bonded to each of said two faces of said panel with cementitious material, said fabric being open and unbonded along said wrapped longitudinal edge of said panel.
A fabric reinforced cementitious panel consisting of a core layer comprising a portland cement material and a light-weight aggregate and a layer of pervious fiber glass scrim bonded to each of the two faces of said core layer with said cementitious material, at least one of the longitudinal edges of said panel being wrapped with said scrim, said scrim being sufficiently open along said panel edge as to permit penetration of joint filling material.
A fabric reinforced cementitious construction panel comprising a cementitious core layer and a web of pervious reinforcing fabric covering the lower face of said core layer, said fabric also wrapping the two longitudinal edges of said panel and covering at least a portion of the top face of said core layer, said fabric being bonded to said faces of said core layer, said fabric being sufficiently open along said panel edges as to permit penetration of joint filling material.
