DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
This invention relates to reduction of the costs of the novel thermoplastic structural system and structural components therefor and building structures erected therefrom which are disclosed in my copending Canadian Application Ser. No. 2,070,079, filed May 29th, 1992 without adversely affecting their integrity.
BACKGROUND OF THE INVENTION
The structural system disclosed in my said copending application comprises novel interlocking thermoplastic structural components which can be mass produced at low cost and which can be quickly and easily interlocked together to erect a wide range of structures which will require minimal maintenance and will be safe from termites, corrosion, rust or rot and will be highly resistant to the effects of weathering.
The present invention is directed to significantly reducing the costs of such components and hence the costs of structures erected therewith without sacrificing the structural integrity of the components or system.
Further the invention is directed to such cost reductions of the components themselves and the structures formed therefrom without increasing the costs of production of the components or interfering with the ease of their assembly.
Further the invention is directed to providing such structural components as to aforesaid which will facilitate the conversion of the walls erected therewith into permanent wall structures, will enhance the air circulation in roofs erected therewith, and will provide reduced thermal transfer between the exterior and interwall surfaces of the walls and roofs.
DESCRIPTION OF PRIOR ART
While the use of plastic to form wall panels or the like for use in building construction has been proposed, such panels have not had the necessary load bearing or other structural requirements to form practical structures which could be mass produced at low cost and quickly and easily assembled to erect durable low cost structures and, in particular, low cost housing.
U.S. Pat. No. 3,992,839, for instance, discloses a plastic panel fabricated from separate panel members, preferably formed of polyvinyl chloride which snap together to form a thin wall panel. The panels in turn are formed to snap together to provide a wall structure. Such fabricated panels are inherently weak and lack the strength and load bearing capacity to form adequate structural components for use, for instance, in the forming of the walls and roof of a practical durable building.
U.S. Pat. No. 3,362,507 discloses the use of tongue and grooved individually prefabricated panels said to be preferably of plastic which are bonded or glued together and used particularly for the forming of basement walls. Such panels do not permit of high speed production and are not capable of being quickly and easily interlocked together in the erection of a house or other structure.
U.S. Pat. No. 4,457,091 discloses a hollow panel member having a width of about one and one-half inches (11/2") and a complicated interior formed by pultrusion, a process involving drawing long glass strands and a plastic binding material forcefully through a die under heat to form the glass strands into a compacted glass mat bound together by the plastic material. Such a process is prohibitively slow and expensive and the panels themselves do not provide acceptable or practical low cost structures for forming the walls and roofing of a housing system such as contemplated by the present invention.
While modular building structures using modular building components formed of steel have also been proposed, such as disclosed in U.S. Pat. No. 1,958,124, such systems involve welding together of the members to make up the components and the use of bolts or other fasteners to secure same together.. Such systems are not practical for low cost practical housing and the like with which the present invention is concerned.
SUMMARY OF THE INVENTION
In accordance with the present invention, the structural building components comprise elongated thermoplastic extrusions presenting spaced interconnectin
