Abstract
Abstract A building which requires a minimum of material is prefabricated by providing a series of prescored glass fibre reinforced double faced corrugated paperboard panels which are folded into rectangular section box beams on site. These box beams, a wooden platform with uprights and a roof ridge beam provide the complete shell for a house incuding the inside walls. Insulation is provided in the box cavity and the assembly can be carried out with unskilled labor using adhesive and stapling devices; prefinished doors and windows can be added as desired. The box beams are thus almost surrounded by a channel of glass fibre reinforcement and T-section splines are placed between channels and bonded to both the webs and base of the channels so that each outside wall and roof comprises an integral glass fibre reinforced shell with webs extending inwardly from the shell.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
194 words
A weather-proof shelter having a load bearing member comprising, in combination: a. a multitude of elongated similar paperboard beams, each beam having at least an outer surface portion and two web portions inwardly thereof to form a U-shaped channel, each of said portions having, on that face thereof which is directed away from the interior of the channel, a reinforcing coating of glass fibers in weather-resistant plastic adhered thereto, the three coatings together being adapted to cooperate to reinforce said three portions, the reinforcing coatings on the outside of the outer surface portions of the multitude of beams being substantially coplanar; and b. a multitude of elongated T-section splines of glass fiber plastic, each spline having a stem and a cross member, thE stem of each spline being between the coatings on the web portions of two adjacent beams and being bonded thereto, and the cross member of each spline being in engagement with the coatings on the outer surface portions of said two beams and being bonded thereto, in consequence of which each spline completes the structural integrity of the juncture of the two adjacent beams between which the respective spline is located.

A weather-proof shelter having a load bearing member comprising, in combination: a. a multitude of elongated similar paperboard beams, each beam having at least an outer surface portion and two web portions inwardly thereof to form a U-shaped channel, each of said portions having, on that face thereof which is directed away from the interior of the channel, a reinforcing coating of glass fibers in weather-resistant plastic adhered thereto, the three coatings together being adapted to cooperate to reinforce said three portions, the reinforcing coatings on the outside of the outer surface portions of the multitude of beams being substantially coplanar; and b. a multitude of elongated T-section splines of glass fiber plastic, each spline having a stem and a cross member, thE stem of each spline being between the coatings on the web portions of two adjacent beams and being bonded thereto, and the cross member of each spline being in engagement with the coatings on the outer surface portions of said two beams and being bonded thereto, in consequence of which each spline completes the structural integrity of the juncture of the two adjacent beams between which the respective spline is located.
Claim 3
Dependent Claim
41 words
The weather-proof shelter as claimed in claim 1, wherein the plastic of the glass fiber reinforcing coatings and the plastic of the glass fiber reinforcing spline are both polyester resins and the bonding material is a vinyl acetate modified polyester resin.
Claim 4
Dependent Claim
52 words
The weather-proof shelter as claimed in claim 1, and further comprising: c. an elongated angle section of glass reinforced plastic bonded to an end beam of the load bearing member at the outer surface portion and a web portion thereof to complete the integrity of an exposed corner of said end beam.
Claim 5
Dependent Claim
31 words
The weather-proof shelter as claimed in claim 3, wherein the angle section has the same dimensions as the stem and one half the cross member of one of said T-section splines.
