  • Process for obtaining hollow structures such as conduits, silos or shelters
    Patent number: 4835936
    Abstract: A process for obtaining hollow structures by assembling a plurality of prefabricated, longitudinal elements each corresponding to a portion of the cross-section of the structure on supports intended to prevent friction between the ground and the base of the structure, the structure being subjected to a prestressing operation in which the elements of the structure are displaced relative to the supports on which they are assembled.
    Type: Grant

    Date of Patent: June 6, 1989
    Inventor: Marcel Matiere
  • Buried large cross-section conduit
    Patent number: 4735234
    Abstract: A buried conduit consisting, in transverse cross-section, of a lower component (2) and a covering upper component (1) which bears on the upper part of the side walls (22) of the lower component (2) by means of lengthwise bearing members (3). According to the invention, the upper component (1) forms an arched vault made so as to have sufficient flexibility to distort slightly under the effect of the forces to which it is subjected, and the lower component (2) is made so as to resist, without distortion, the forces transmitted by the ground and by the upper component (1), both components being fixed to each other along the lengthwise bearing members (3) and the latter consisting of socket joints, so as to permit the bearing parts of the distortable upper component to pivot without sliding relative to the undistortable lower component.

  • Method of producing hollow structures and hollow structures
    Patent number: 4693635
    Abstract: A method for producing cylindrical hollow bodies bearing on the ground along one generatrice, of large cross sectional area, by assembling on site previously prepared longitudinal components.The method consists in determining by calculation the optimum cross-sectional profile of said hollow body as a function of known parameters concerning the site, conditions of use of said hollow body and its inherent characteristics; divising said optimum cross-sectional profile into adjacent sections each corresponding to a longitudinal component of the hollow body and together providing a substantially continuous interior surface; and giving the transverse wall section of at least some of said components a variable thickness for adapting the latter component to the stresses to be exerted thereon.

  • Modular construction system for a covered structure
    Patent number: 4685829
    Abstract: The invention relates to a modular construction system for a covered structure of large section produced by assembling prefabricated elements, namely floor elements (1), side elements (2) placed on each side of the floor, and roof elements (4).
