Title: Method of constructing buildings and other structures using corrugated material

Description:
The present invention relates generally to a method of constructing buildings and other structures and, in particular, a quick and inexpensive method of constructing buildings and other structures using corrugated material. 
     BACKGROUND OF THE INVENTION 
     The need to quickly construct inexpensive structures such as homes or other types of buildings is ever present. Further, these structures must be soundly built to accommodate the forces of nature including natural disasters and/or man-made disasters such as a fire. For example, should a natural disaster such as a hurricane strike, hundreds or thousands of people might be left without housing. This situation is magnified if such a disaster occurs in a poorer section of the world where many of the people would not have the means necessary to quickly rebuild or relocate. Therefore, there is a need to have numerous housing structures, whether temporary or permanent, to be built in a quick, efficient and inexpensive manner. 
     Further, these structures must be strong and secure such that they may be lived in safely and permanently if needed or desired. Accordingly, there is a need for a strong, relatively lightweight, inexpensive, fireproof and easy to assemble construction material and method of constructing buildings and other structures. Prior art construction material and systems have failed to adequately meet these needs.

Mancini, et al. does not disclose a quick and inexpensive method of constructing buildings using corrugated material as does the present invention. 
     U.S. Pat. No. 3,031,044 issued to Stitt, et al. discloses a fire retardant wall construction. Stitt, et al. differs from the present invention in that the wall comprises two sets of spaced apart panels between which are arranged four panels of fire retardant material and utilizes a complicated clip mechanism to attach the structure. Stitt, et al. does not disclose a quick and inexpensive method of constructing buildings using corrugated material as does the present invention. 
     U.S. Pat. No. 683,060 issued to New discloses an insulating construction. New differs from the present invention in that the insulating construction comprises a wooden block having a plurality of partitions therein spread or separated by air-spaces. New does not disclose a quick and inexpensive method of constructing buildings using corrugated material as does the present invention. 
     U.S. Pat. No. 3,192,099 issued to Beckman, et al. discloses a furniture panel. Beckman, et al. differs from the present invention in that the furniture panel comprises a corrugated, foam sandwich core enclosed by a jacket having a decorative exterior.

     U.S. Pat. Nos. 5,215,806 and 5,032,447 issued to Bailey disclose a fire barrier material for use in building construction. Bailey differs from the present invention in that the fire barrier material is used in conjunction with wall, ceiling or floor expansion joint systems. Bailey does not disclose a quick and inexpensive method of constructing buildings using corrugated material as does the present invention. 
     U.S. Pat. No. 897,158 issued to Ryan discloses a plaster board. Ryan differs from the present invention in that the plaster board comprises of a layer of plaster of paris, a sheet of coarse burlap, a second plaster layer and a second sheet of burlap to which asbestos is applied. Ryan does not disclose a quick and inexpensive method of constructing buildings using corrugated material as does the present invention. 
     SUMMARY OF THE INVENTION 
     The present invention relates to the manufacture of a prefabricated building sections which are easily and quickly mounted together to form an entire building or structure. The sections, described in my co-pending U.S. application Ser. No. 08/199,590 for &#34;METHOD OF CONSTRUCTION USING CORRUGATED MATERIAL&#34; are made of gypsum board mounted on either a double or triple layer of a length of U- or C-shaped corrugated cardboard in approximately two foot widths. The completed sections are then used in home or building constructions. 
     Within the shaped cardboard is a sheet of fireproof foam. Metal stays bolted in place at the ends and corners of the corrugated cardboard, used to attach sections together, assist in the rigidity of the resulting sections and building structures. 
     A first section, preferably a wall section, is made up of a outer layer of gypsum board laminated to a layer of corrugated, which is laminated to a layer of fireproof or fire resistant foam. The sides of the corrugated fold inward to form the structural studs of the section. 
     In a second section, preferably a roof section, the outer layer of gypsum board is laminated to a layer of corrugated followed by a layer of foam followed by an additional layer of corrugated. The ends of each layer of corrugated fold outward to form the structural studs of this section. The sections are fastened together at the structural studs. 
     Accordingly, it is an object of the present invention to provide construction material and a method of constructing buildings and other structures using corrugated material. 
     It is another object of the present invention to provide pre-fabricated building sections which can be quickly and inexpensively used to construct or form a structure. 
     It is an additional object of the present invention to provide a building section which is strong and secure with which a structure can be constructed solely out of the material of the pre-fabricated building sections. 
     It is a further object of the present invention to provide a structure formed from a plurality of fireproof building sections using corrugated material. 
     It is yet another object of the present invention to provide a method of constructing utilizing pre-fabricated building sections containing corrugated material. 
     It is a still further object of the present invention to provide a plurality of pre-fabricated building sections which can be quickly assembled into a building or other structure utilizing only a simple tool which can fasten bolts in metal stays.

     Before construction, interior and exterior surface of sections 10 and 110, including the corrugated flaps, are coated with a fire-retardant material (i.e. paint) to make sections 10 and 110 completely fireproof and prevent spontaneous combustion. Fire resistancy is preferably obtained by the use of Tough/Coat fire resisting paints, manufactured by Space Age Technology Products, Inc. of Chicago, Ill., used as a primer coat for the corrugated material. The Tough/Coat paints also give a water-resistancy to and strengthen and stiffen the corrugated material. 
     All building sections will be pre-drilled to allow for simple and fast construction. A builder only need use basic bolt fastening tools. The sections of the present invention can be cut to accommodate windows, doors, etc. The layers of the present invention can be fastened together in any suitable manner. Preferably, the layers are laminated or glued to one another by any suitable adhesive means, prior to the drilling of holes for fasteners 60, 160. 
     The sections 10, 110 can be used in the construction of building or other structures. Construction using sections 10, 110 is fast, safe and efficient and can be achieved at a far less expense than present construction material. Sections 10,110 could be any shape or size but preferably are two foot wide panels with a length approximately that of a wall board or plastic board. 
     The wall sections 10 which form the short sides of building 200, perpendicular to roof apex stud 239, are preferably successively cut at a rising slope at their roof ends. These wall sections are cut in this manner to provide a sloped roof once the roof sections 110 are attached. The slope of the roof can vary as desired. Sections 10 and 110 can be modified slightly as desired or needed to ensure proper fit or connection. For example, a side flap could be cut-off at a wall corner connection to ensure proper connection. 
     Building 200 could be any size or shape. The windows of the building are preferably made from acrylic, not glass. The ceiling beam could be a pipe instead of wooden beams. The T-shaped and J-shaped plastic strips are held in place by any suitable fastening means, such as a screw. 
     It is to be understood that the embodiments herein described are merely for illustrative of the principles of the present invention. Various modifications may me made by those skilled in the art without departing from spirit or scope of the claims which follow.
