Abstract

Abstract Building frame units and building structures using such frame units as load-bearing wall sections or wall panels are disclosed. The frame units comprise hollow metal sections providing longitudinal frame members, end frame members and intermediate pillar frame members interconnected to form a rectangular skeletal frame. The top and bottom longitudinal frame members and the intermediate pillars are each composed of a pair of flanged channel sections assembled mouth-to-mouth and connected by C-cleats. The end frame members are each formed by a single flanged channel section having its open mouth presented outwardly. At least some frame units incorporate fittings such as windows and doors, but all residual spaces between adjacent frame members are closed by a sheet-like infill of plastics foam material providing a sealing and insulating barrier. A building structure is fabricated by assembling and erecting the frame units in endwise interconnected relationship upon a pre-constructed and levelled horizontal sub-frame base foundation.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 182 words
A method of constructing in situ a building structure having a plurality of building frame wall units disposed upon a supporting base foundation, said method comprising the steps of: (a) juxtaposing a plurality of elongate sub-frame sections to define a horizontal skeletal base sub-frame, (b) releasably fastening adjacent sub-frame sections together externally of the sub-frame, (c) releasably fastening a plurality of separate individual base plate means to said sub-frame sections, (d) connecting tie rods between at least some of the base plate means to brace the sub-frame sections of the base sub-frame, (e) leveling and trueing the sub-frame to fix all the base plate means in precise predetermined final positions with respect to each other before casting, then (f) casting a molded floor slab of rigid hard-setting molding material within said sub-frame to fix said base plate means and tie rods into said floor slab; and (g) removing said sub-frame sections so that the base sub-frame is dismantled and the base plate means and tie rods remain fixed into the floor slab to provide the supporting base foundation of the building structure.
Claim 2
Independent Claim 182 words
A method of constructing in situ a building structure having a plurality of building frame wall units disposed upon a supporting base foundation, said method comprising the steps of: (a) juxtaposing a plurality of elongate sub-frame sections to define a horizontal skeletal base sub-frame, (b) releasably fastening adjacent sub-frame sections together externally of the sub-frame, (c) releasably fastening a plurality of separate individual base plate means to said sub-frame sections, (d) connecting tie rods between at least some of the base plate means to brace the sub-frame sections of the base sub-frame, (e) leveling and trueing the sub-frame to fix all the base plate means in precise predetermined final positions with respect to each other before casting, then (f) casting a molded floor slab of rigid hard-setting molding material within said sub-frame to fix said base plate means and tie rods into said floor slab; and (g) removing said sub-frame sections so that the base sub-frame is dismantled and the base plate means and tie rods remain fixed into the floor slab to provide the supporting base foundation of the building structure.
Claim 3
Dependent Claim 43 words
A method as defined in claim 1, wherein a flexible sheet of plastic material is disposed over the entire upper surface of the molded floor slab and base plate means before erecting and fixing building frame wall units on the supporting base foundation.
Claim 4
Dependent Claim 33 words
A method as defined in claim 2, wherein channel section shoe means are fixed at intervals along the supporting base foundation to receive bottom horizontal frame members of said building frame wall units.
Claim 5
Dependent Claim 70 words
A method as defined in claim 1, wherein building frame wall units are erected and fixed in endwise interconnected relationship with respect to each other on the supporting base foundation, and roof trusses are fitted to span between building frame wall units of the external wall located at opposite sides of the erected structure of wall units and are connected to and supported by the top of said wall units.
Claim 6
Dependent Claim 41 words
A method as defined in claim 1, wherein apertures are located between horizontal frame members and vertical frame members in the building frame wall units composed of skeletal metal frames, and a thermally insulating rigid plastics foam material fills said apertures.
Claim 7
Dependent Claim 54 words
A method as defined in claim 5, wherein the horizontal and vertical frame members each have a hollow box-like interior including a pair of channel sections having inturned and re-entrant marginal flanges assembled in opposed mouth-to-mouth relationship, the hollow box-like interior of said frame members being filled with thermally insulating rigid plastics foam material.
Claim 8
Dependent Claim 56 words
A method as defined in claim 1, wherein the skeletal base sub-frame has a rectangular configuration and the base plate means includes a plurality of brackets each having an angular configuration and being positioned with one at each corner and at least one along each side defined by an elongate sub-frame section and intermediate adjacent corners.
Claim 9
Dependent Claim 30 words
A method as defined in claim 1, wherein building frame wall units are erected and fixed in endwise interconnected relationship with respect to each other on the supporting base foundation.
Claim 10
Dependent Claim 60 words
A method as defined in claim 8, wherein said base plate means includes a plurality of base plate elements positioned at each corner of the supporting base foundation and along each side of the foundation intermediate adjacent corners, each building frame wall unit has a bottom horizontal frame member which is spanned over and supported by adjacent base plate elements.
Claim 11
Dependent Claim 36 words
A method as defined in claim 1, wherein a plurality of said frame wall units are connected by C-cleats engaged with respective pairs of adjacent re-entrant flanges of the channel sections to form box-like elongate structures.
