  • Patent number: 4799348
    Abstract: Pin point foundations are formed, the ground is flattened and levelled at the level of these foundations, peripheral recoverable shuttering is disposed on the ground and continuous rows of non recoverable shuttering defining the ribs are disposed at the center. The rows of shuttering are spaced apart by baryte cardboard elements providing sealing and insulation. On the upper face of the non recoverable shuttering are disposed means for spacing the trellis work reinforcing the floor. Then the concrete is poured by pumping and, after drying out the floor, only the peripheral shuttering is recovered.

  • Patent number: 4794742
    Abstract: A multi-conic shell and a process of creating multi-conic shells from flat materials which are bent and thereby forced into the configuration of continuous regions from oppositely oriented, tangential cones to create variably configured building structures and variably configured lightweight structural panels. The process of creating multi-conic shells from connecting cone segments corresponding to a theoretical array of regular (opening downward) and inverted (opening upward) cones provides an unlimited number of variations for the design of building structures and the design of structural panels. Such multi-conic structures achieve excellent strength to weight ratios by distributing loads into tension and corresponding tetrahedron structures which propogate throughout the shell.

  • Patent number: 4773195
    Abstract: A method and related apparatus for forming a sluiceway adjacent a wall and cement floor includes a sluiceway form made from a generally rectangular sheet of biodegradable material having a number of generally parallel fold lines to define a plurality of contiguous sluiceway panels disposed inwardly of opposite marginal portions of the sheet which are folded into face-to-face relation with each other to form an elongated sluiceway form having a body portion defined by the sluiceway panels and a tab defined by the marginal portions projecting from the body portion and extending along the entire length of the body portion. The sluiceway is formed by positioning the sluiceway form adjacent the wall with at least a part of the body portion below the level of the grade and the free edge of the tab extending in a generally parallel relation to the grade level. The tab is secured to the wall and the concrete floor is poured with the sluiceway form in position.

  • Patent number: 4750301
    Abstract: The use of a bifurcated joint to attach a conveniently sized metal flange to a flexible bellows material has been widely used, for example, in the manufacture of a building construction expansion joint cover. The known bifurcated joint is formed by clamping and engaging a marginal edge of the bellows material between opposed folded portions of the metal flashing. It has been found that the attaching force provided by this joint can be enhanced by providing teeth or protrusions in a portion of the metal bifurcated joint. Preferably a punch is used to upset teeth from one surface of the joint, preferably a corrugated portion of the joint, and then bend the thus toothed and corrugated portion into clamping engagement with the marginal edge of the bellows. The toothed hole clampingly engages the bellows material without piercing it and prevents pull out, both prior to curing of the adhesive bond as well as thereafter.
