    Abstract: A shear frame assembly of the type having a pair of tensioned diagonal straps that provide resistance to shear loads. The shear frame assembly includes a pair of laterally opposed vertical supports each having a first end portion and each vertical support has an aperture in its first end portion. The aperture is sized to receive one of the tensioned diagonal straps therethrough. Transverse top and bottom plates extend between the end portions of the vertical supports. A strap-alignment member is positioned in each aperture and each alignment member is positioned to receive and align the tensioned strap within the aperture. A force distributing member is positioned in each aperture and interposed between the alignment member and the respective vertical support.

  • Patent number: 6067769
    Abstract: The reinforcing brace frame is utilized in building walls as a complete system of protection against both the severe shear stress and uplifting encountered during tornados, hurricanes and earthquakes. The reinforcing brace frame includes two vertically-spaced horizontally extending frame members joined at their opposite ends to two horizontally-spaced vertically extending frame members, and a diagonal member rigidly connected to opposite ends of the horizontally extending frame members. The reinforcing brace frame can also include spaced vertical support members between the vertical frame members. The reinforcing brace frame is directly attached to a concrete foundation by shear bolts and hold down bolts. Consequently, the reinforcing brace frame provides increased resistance against simultaneous shear stress and uplifting, eliminating the need for plywood shear panels.

  • Patent number: 5937608
    Abstract: Bridging is provided for use in joining joists or like construction elements so as to increase the strength and stability of those elements. The present invention utilizes flexible strapping to create the bridging structure, wherein a first flexible strap is attached to a first joist and a second flexible strap is attached to a second joist. The bridging structure is created by aligning the straps between the joists and joining the straps together. The various flexible straps can be directly attached to the joists, however when applied to wooden joists, stiffened supports are preferably positioned between the joists and the flexible strapping. The stiffened supports spread the force of the flexible strapping and prevent the strapping from deforming the material of the joist. To add to the integrity of the bridging structure, the stiffened supports can be mechanically or adhesively joined to the joists and the flexible strapping can be mechanically or adhesively joined to the stiffened supports and joists.

  • Patent number: 3975874
    Abstract: A swimming pool having sidewalls constructed from a series of prefabricated modular panels connected at the ends to enclose the interior of the pool. The panels are preferably formed of foamed synthetic resinous composition and of a limited number of configurations or modules which are interchangeably adapted for use in forming pools having a plurality of shapes, e.g. a straight panel, a concave curved panel and a convex curved panel. Each panel is adapted to mate and lock with the adjoining panel, and with an upper end with flanges and rib arrangements which are functional as well as serve to strengthen the panel. In a specific embodiment, a tongue is formed on the flange on one side and a mating groove on the flange on the other side of each panel for instant connecting and interlocking of adjacent panels when they are assembled in forming the pool wall. A sealing strip may be placed within the groove and abuts on the tongue of the adjoining panel thereby precluding leakage between the panels.

  • Patent number: RE34103
    Abstract: A lattice bridge construction system is characterized by the provision of lattice panels (A,B,C) which are of substantially identical length but of different depths relative to one another such that when variously combined one with another, with or without additional reinforcement, trusses having considerably more economic increments of bending strength may be achieved.
