Rigid structural members and structures for buildings and retaining means for securing sheets thereto

A holding member for insertion into a groove of a rigid structural member comprising a base and two legs extending in laterally spaced relationship away from the base, the legs being relatively flexibly movable towards each other or apart, one of the legs having a locking free end portion which is flexible upon its associated leg and in a normal position is inclined in a direction generally towards the other leg, the legs being insertable in positions moved toward each other through a narrow opening and into the groove and, during insertion, the locking free end portion is engagable with a surface of the groove to cause deflection of the free end portion from the normal position and apply pressure to the other leg and hold the legs apart to retain the legs within the groove.

A kit comprising a plurality of building sections, each building section formed by four elongate rigid structural members each having four sides each of which is formed with a groove extending longitudinally of the member, the member also having lip means defining a narrow opening to each of the grooves, the four structural members of each section hinged together end to end for folding flat for transport and storage, and for unfolding to form a pair of upright members and a pair of roof members, and a plurality of spacers and fastening means for interconnecting adjacent unfolded ones of said plurality of building sections in spaced relation to form a building structure.

A structural assembly for a building comprising two wall structures and two roof structures, each structure comprising two main elongate rigid side structural members each having four sides, each side formed with a groove extending longitudinally of the member, each member also having lip means defining a narrow opening to each of the grooves, and the two main elongate rigid side structural members are located at the sides of the structure and are held spaced apart by secondary elongate rigid structural members extending between and secured to the main structural members with two of the grooves of each main member provided in oppositely outwardly facing sides of the structure to provide grooves for releasably accepting panel holding members for mounting upon the structure two panels extending in face-to-face relationship across the two opposite sides of the structure, and the structures are hinged together in series as an assembly with the two wall structures at ends of the series and separated by the two roof structures, the structures being relatively movable about hinged positions between an erected state of the assembly and a collapsed state of the assembly.

An elongate rigid structural member having four sides, each of which is formed with a groove extending longitudinally of the member, the member also having lip means defining a narrow opening to each of the grooves, wherein each groove has a bottom surface which is convex in a lateral cross-section of the groove.
