Building construction system

A method of constructing a panel assembly for a building structure, the method including the steps of erecting a support frame on a substrate, the support frame including a plurality of members extending in a first direction, all of the members extending in the first direction being first members and at least two members extending in a second direction, all of the members extending in the second direction being second members each of the first members and second members having at least a pair of attachment surfaces extending parallel to each other, each of the said parallel attachment surfaces of each said first member and each said second member attaching either structural sheeting or other first members or second members through the respective parallel attachment surfaces, attaching structural sheeting on the support frame so that the support frame is positioned between a pair of structural sheets and the support frame and structural sheeting together define a zone in which cementitious material is to be set, applying a cementitious, settable material to an inner surface of the structural sheeting to at least partially fill the zone with the settable material;

• and allowing the cementitious material to set.

A panel assembly for a building structure including a support frame that is mountable relative to a building substrate, the support frame including a plurality of first members extending in a first direction, all of the members extending in the first direction being first members and at least two members extending in a second direction and overlaying the members in the first direction, all of the members extending in the second direction being second members, each of the first members and second members having at least a pair of attachment surfaces extending parallel to each other, each of the said parallel attachment surfaces of each said first member and each said second member attaching either structural sheeting or other members through the respective parallel attachment surfaces, at least one sheeting member attached on at least one side of the support frame so that the support frame and the structural sheeting define a zone for a cementitious material, and a layer of cementitious material positioned against the structural sheeting to at least partially fill the zone.

A building construction system including a panel assembly for a building structure including a support frame that is mountable on a substrate, structural sheeting provided on the support frame so that the support frame is positioned between a pair of structural sheets and the support frame and the structural sheeting together define a hollow zone between the structural sheeting wherein the support frame includes a plurality of members extending in a first direction, all of the members extending in the first direction being first members and at least two members extending in a second direction, all of the members extending in the second direction being second members, each of the first members and second members having at least a pair of attachment surfaces extending parallel to each other, each of the said parallel attachment surfaces of each said first member and each said second member attaching either structural sheeting or other first members or second members through the respective parallel attachment surfaces.

A method of forming a panel assembly including the steps of erecting a support frame on a substrate, the support frame including a plurality of members extending in a first direction, all of the members extending in the first direction being first members and at least one member extending in a second direction, all of the members extending in the second direction being second members, each of the members having at least a pair of attachment surfaces extending parallel to each other, attaching structural sheeting on the support frame so that the support frame is positioned on one side of the structural sheeting, the support frame and structural sheeting together define one or more hollow zones in which cementitious material is to be set, initially applying the cementitious settable material to an inner surface of the structural sheeting in some of the hollow zones, allowing the material in those zones to at least partially set, applying the settable material to remaining zones, and using the at least partially set material in the zones as a guide for screeding the material in the remaining zones;

• and allowing the cementitious material to set.
