Abstract
Preformed concrete panels are described for use in the construction of buildings. Roof panels are designed such that they have self-sealing abutting edges when assembled, and the roof panels interlock with wall panels and, preferably, with other roof panels supported by a center building beam. One type of wall panel has a support member projecting form one surface which is adapted to support a floor structure.
Claims7
A roof structure comprising a plurality of concrete building panels supported, by a supporting means, in abutting edge-to-edge relationship, each said building panel having a downwardly projecting rib extending along each of two opposite side edges on the bottom surface of said panel, each said rib being integral with said bottom surface, a layer of foam covering said bottom surface and extending around each said rib so as to at least partially cover said opposite side edges of said panel, wherein the thickness of each rib is greater at said bottom surface of said panel than at the projecting end of said rib, wherein abutting edges of said panels are received in and supported by a V-shaped notch in said supporting means. whereby said foam on said abutting edges of said plurality of panels is compressed so as to form a seal.
A method for interconnecting abutting ends of roof panels of the type which are supported by a central beam, wherein the method comprises the steps of:
- a. positioning one end of a first roof panel on said central beam, said end of said panel having a projecting step, integral with said panel, which is adapted to be supported by, and connect to, said central beam, and said end being covered by a layer of foam,
- b. connecting said end of said first roof panel to said central beam.
- c. positioning one end of a second roof panel solely on said projecting step of said first roof panel, wherein said end of said second roof panel is complementary to said end of said first roof panel and is adapted to connect thereto, said end of said second panel being covered by a layer of foam,
- d. connecting said end of said second roof panel to said end of said first roof panel by means of a pin and a tongue-in-groove connection, whereby said foam on said ends is compressed so as to form a seal.
