ABSTRACT:
TECHNICAL FIELD
The present invention relates to a prefabricated self-supporting building structure consisting of a plurality of substantially triangular shaped panels which are interconnected to form roof segments which are easy to erect and to connect together.
BACKGROUND ART
Various prefabricated building structures are known and the majority of these comprise pre-casted or pre-assembled panel structures which are transported to an erection site and assembled. Although many of the component parts of the buildings are pre-fabricated, the erection time can be fairly lengthy and inclement weather conditions can further slow down the erection time as well as expose building materials to rain or snow which sometimes will cause the materials to become damaged. Often, the pre-assembled parts are difficult to transport and the transport vehicle must be operated at slow speed, particularly in a situation where an entire home is prefabricated in two sections. They require long trailer vehicles and special vehicles to warn oncoming traffic of the danger of the wide load on the transport vehicle.
Another disadvantage of prefabricated structures is that they are heavy to manipulate and often require large cranes which are expensive. Many of the prefabricated or other type home or building structures are constructed for permanent installation and cannot be easily dismantled and reassembled on another site. A still further disadvantage of prefabricated structures is that often these are not very structurally sound and can become damaged if exposed to tornadoes or hurricane force winds. A still further disadvantage is that some of these structures are erected directly on a slab of cement which is poured on the ground and therefore are easily exposed to flooding with resulting serious damage. Some of these are also not well insulated or resistant to insect infestation such as by termites. Often, their construction causes condensation to set into the structure which can also affect building materials. Still further prefabricated building structures require expensive foundations made of concrete thereby increasing the cost of the prefabricated structure.
Typical examples of prefabricated structures can be found in U.S. Pat. Nos. 5,960,593; 5,950,374; 5,758,461; 4,660,332; 5,904,005; 5,921,047; 4,741,133; 4,912,891; 5,765,316; 5,797,224 and 5,461,832.
SUMMARY OF INVENTION
It is a feature of the present invention to provide a prefabricated self-supporting building structure and a method of erecting such building structure and which substantially overcomes the above-mentioned disadvantages of the prior art.
According to the above features, from a broad aspect, the present invention provides a prefabricated, self-supporting, building structure which is comprised of a plurality of substantially triangular shaped panels. Each of the panels has a front edge, a straight top edge, a straight hypotenuse edge and a junction point at an intersecting end of the hypotenuse edge and the front edge. The panels are connected in juxtaposed pairs by a hinge connection means which interconnects the top edge of each juxtaposed pair of panels to form a collapsible roof segment. There are four roof segments interconnected together in side-by-side relationship at right angles to one another to form the building structure. Each panel of the juxtaposed pairs of panels are connected along their straight hypotenuse edge by a further hinge connection means to the straight hypotenuse edge of a panel of an adjacent roof segment. Attachment means is provided at the junction point of the panels for securing the roof segments in elevated position on a support means. Connector means are provided at a forward end of the top edge of at least one panel of two of the roof segments interconnected back-to-back for attachment to pulling means. The pulling means causes the panel segments to be erected to form a roof structure anchored at the attachment means.
The method consists essentially of connecting the attachment means at the junction point of the roof segments of two panel sections to a support means and connecting a pulling cable to the connector means at a forward end of the top edge of the roof segment of two panel sections. The two panel sections are erected back-to-back by pulling the cable with the further panels of each of the two panel sections having their straight top edge at right angles to the straight top edge of its associated roof segment. Adjacent ones of the top edge of the further panels are secured together by ridge capping connection means whereby to secure the two panel sections together back-to-back and to form a building structure having four roof segments disposed at right angles to one another.
Floor segments can also be secured under the building structure and connected to the roof segments.
