Claims
- 1. A method of constructing a polygonal building comprising:
- providing a plurality of precast concrete "T" beamed roof-floor panel elements, a plurality of pre-cast wall panels elements a plurality of hollow precast central core ring members and a plurality of vertical piers,
- casting a foundation comprised of at least a central concrete slab and a plurality of remote slab elements equal to the number of said floor panels and spaced in equal angular increments about said central concrete slab,
- stacking a first plurality of said precast central core ring members, one on another, on said central slab,
- securing one vertical pier on each remote slab element and having upper load bearing surface which is coplanar with the upper edge of the upper one of said first plurality of precast core members,
- placing said floor members in edge to edge juxtaposition, resting one beam on said upper edge of said upper ones of said first plurality of central core elements and the other end on the said upper load bearing surface of said pier, respectively,
- stacking a second plurality of said precast central core members, one on another on said floor panel members in axial alignment with said first plurality of central core elements,
- placing said wall panel elements in end to end relation directly on the load bearing surfaces of said piers with the lower edges thereof being below said floor panels,
- securing each panel to said piers and to said floor panels, and
- placing said roof members in edge to edge juxtaposition, resting one beam end on the joint between two wall panels and the other beam end on the upper edge of the last one of said second plurality of precast central core elements.
- 2. The invention defined in claim 1 wherein the step of securing each panel to said piers and said floor panels is by welding.
- 3. A method of rapidly constructing a monolithic polygonal building having interior angles of other than 90.degree. comprising the steps of:
- providing a plurality of precast concrete "T" beamed roof-panel elements constituted by a complementary pair of non co-planar triangularly shaped panels having a common base line integral with a concrete beam at said base line, piers and a plurality of hollow precast concrete central core ring members,
- casting a concrete foundation comprised of at least a central concrete slab portion and a plurality of remote slab elements equal in number to the number of said precast concrete "T" beamed roof panels and spaced in equal angular increments about said central concrete slab,
- stacking a first plurality of said precast central core ring members, one on another, in vertical axial alignment with each other on said central slab portion,
- securing one pier vertically on each remote slab element, each pier having a sloping, upper load bearing surface,
- placing said precast concrete "T" beamed roof-panel members in edge to edge juxtaposition, securely resting one beam end on each precast concrete "T" beamed roof-panel member on said upper edge of said upper one of said plurality of core elements respectively and the other end on the said sloping upper load bearing surface of said pier, respectively with the central axis of each concrete "T" beamed roof-panel element intersecting each other and the central axis of the stacked concrete central core elements, and securing all edges of "T" beamed panels in edge to edge juxtaposition to each other by welding.
- 4. The method defined in claim 3 wherein one side each of said complementary pair of non co-planar triangularly shaped panels forms a straight line with a side of a triangle of the complementary pair having the edge juxtaposed and securing a rigid straight building panel to said one side forming said straight line.

This is a division of application Ser. No. 767,590 filed Feb. 10, 1977, now U.S. Pat. No. 4,100,705.
There are a number of polygonal building structure systems known in the art with particular reference being made to those found in the Patent Office classification Class 52, Subclass 82. A number of these polygonal buildings are formed of prefabricated elements, usually wood or metal, with various forms of interfitting edges and joints for the prefabricated elements, see for example Vachon U.S. Pat. No. 3,727,355 and Preissler U.S. Pat. No. 3,827,200. Precast modular elements, for assembling concrete building structures and the like, are usually rectangular elements which seek to utilize the economic advantages of factory-made buildings and to minimize the time and mechanical operations and expense required for erection and other on-site work. See, for example, Lafferty U.S. Pat. No. 2,222,037. These structures may also utilize prestressing of precast sections, typically floor and roof panels, such as is disclosed in Dobell U.S. Pat. No. 2,776,471 and Ali-Oglu U.S. Pat. No. 3,562,979. These prior precast systems generally result in buildings which are boxy in appearance and otherwise generally unattractive.
The object of the present invention is to provide improvements in precast polygonal buildings and methods of constructing same. The present precast polygonal building structure reduces construction time to approximately twelve hours on-site erection time for a dwelling-type structure and thereby minimizes the costly on-site job labor. Moreover, it reduces delays in planning and scheduling and extends the construction seasons to all year round. By being constructed of concrete and/or other low cost castable cementious type building materials, the material has high durability, is fire resistant and essentially maintenance free. A wide variety of finish materials may be incorporated into the design and the control of the quality as well as performance for the building structure is assured. The internal layout of the building is open since the roof and floor panel elements are integrally beamed panel members. A built-in insulation may be incorporated in the wall panels for lowering energy consumption and the geometry of the roof structure is highly conductive to solar energy application.
The above and other objects, advantages and features of the invention will become more apparent from the following specification when taken in conjunction with the accompanying drawings wherein:
