Abstract: An expansion joint system for a wall is provided herein wherein a first concrete wall component is substantially separated from a second concrete wall component via a rigid plate such that contraction of the first concrete wall component does not create significant stresses in the first or second concrete wall component so as to create cracks in the first or second concrete wall component. Moreover, a compressible material may be disposed between the rigid plate and/or the first and/or second concrete wall component such that expansion of the first concrete wall component compresses the compressible material instead of imposing significant stresses on the first or second concrete wall component so as to be likely to form cracks in the first or second concrete wall component.

Abstract: Disclosed is a crash paddle for reinforcing a primary fuselage structure of an aircraft. The crash paddle may be used for connecting the floor to the primary fuselage structure. The crash paddle includes a beam with in particular an H-shaped cross-sectional geometry, butt straps being arranged at both ends of the beam for connecting the crash paddle. In the region of the ends of the beam, the beam respectively has a resting surface 13, 14, the geometrical shape of which substantially corresponds to a hollow cylinder halved in the longitudinal direction. Placed around both resting surfaces and the longitudinal sides of the beam, in a peripheral groove is at least one endless loop. The endless loops respectively comprise an arrangement of reinforcing fibers, which is formed by a plurality of reinforcing fibers, such as for example carbon fibers, running substantially parallel to the longitudinal axis of the beam.

Abstract: A knockdown structure and assembly method are provided so as to prevent cracking of the sealant, reinforce the junction between sections, and improve the livability of the structure. A structure's body is assembled by using a mortar-powder mixed adhesive to join together a plurality of sections that are made of foam polystyrene and that constitute the parts of a structure having a predetermined shape. The adhesive is applied to cover at least the places where the sections are joined together with a woven inorganic-fiber mesh sheet. A sealant is applied, made by dispersing inorganic fiber and mortar powder in a plastic-type paint, onto the exterior and interior faces of the structure in a predetermined thickness. Onto the sealant of the exterior of the structure is applied, on the exterior of the structure, a paint that is water repellant and can screen out ultraviolet light, and applying, over the sealant of the interior of the structure, a clayey paint made of natural substances.

Abstract: This invention concerns an arch structure. In particular, the invention relates to an arch structure comprised of at least two segments which are rotatably linked to each other via hinges or equivalent means to form a continuous bendable chain of attached segments. The segments have magnets above the rotatable or hinged link on opposed end faces, positioned to oppose magnets on confronting end faces of adjacent arch segments, with like poles facing one another, thereby creating a repulsion force. The repulsion force inhibits the arch segments from being brought together and into contact. Due to this effect, the aggregate of the arch segments define an arcuate path (convex upward), maintained by the repulsion forces of the magnets.

Abstract: The panel-like laminate comprises a flexible skin (1), a rigid substrate (2) and an intermediate layer (3). The flexible skin (1) comprises a main part (8) which forms the front side of the laminate and at least one flange (9) which extends from the main part (8) of the skin towards the substrate (2) to form at least a portion of the lateral side of the laminate. In order to avoid foam leakage when molding the intermediate layer (3) between the skin (1) and the substrate (2), the flange (9) is extended by a border part (10) which comprises a flexible lip (11). The flexible lip is pressed against the rigid substrate (2) so that the flexible lip (11) forms a seal between the skin and the substrate. To prevent deformation of the skin, the border part (10) of the skin further comprises at least one continuous or discontinuous ridge (12) which extends along the flange (9) of the skin (1) and which prevents a sliding of this border part when closing the mold.

Abstract: A plurality of elongated panels of light transmitting plastics sheet material each have longitudinally extending parallel spaced ribs and longitudinally extending co-planner opposite edge portions. An elongated support member for each panel has a base portion secured to the opposite edge portions of the panel adjacent the upper end portion of the panel and includes a hook portion adapted to engage a hook-shaped support rail mounted on a building over a window or door opening. Each hook portion has end surfaces recessed inwardly from opposite edge surfaces of the panel and provide for overlapping edge portions of adjacent panels. The lower end portion of an outer panel is supported by a sill bracket mounted on the building under the opening and receives a U-shaped track member secured to the panel. The bracket and track member are connected by pull pins located within the ribs of the outer panel.

Abstract: Methods and systems for plugging a hole are described. A plug may comprise a substantially tubular member having a proximal end and a distal end interconnected by a side wall, the side wall having an inward facing surface and an outward facing surface, at least the outward facing surface being substantially conformable, an adhesive disposed on the outward facing surface, a fire-resistant ring disposed substantially at one of the ends of the tubular member, and a thread disposed along the inward facing surface, the thread adapted to receive a cover.

Abstract: A tornado resistant dome house. The shape of the dome house is a spheroid section, and is given by a formula. The dome house shell is made up of a plurality of tiles formed to conform to the shape of the dome house. The tiles are mutually connected by means of horizontally and vertically disposed elongate members extending through lumens in adjacent tiles. The tiles are also attached to a dome house foundation. The curved, low-profile shape of the house, combined with the mutual attachment of the tiles, and their attachment to the dome house foundation, improves the resistance of the dome house to high winds associated with tornadoes and hurricanes. Adjacent tiles are cushioned by springs, and are maintained in position relative to each other by means of a tongue-in-groove attachment between adjacent tiles.

Abstract: A double sliding door arrangement cooperating with a double-wide door opening formed in an upright wall. A top header beam extends across and defines the upper extremity of the door opening. A pre-tensioning arrangement mounted on and extending lengthwise of the top header beam causes the header beam to be deflected upwardly into a shallow bowed shape. A support track is fixed to and extends lengthwise of the header beam and horizontally for predetermined distances along and rigidly fixed to the wall adjacent right and left sides of the door opening. Right and left slab doors are supported on and vertically suspended downwardly from said track in sidewardly co-planar relationship, and are movable along said track between closed and open positions. The doors in the closed position vertically load and downwardly deflect the header beam, whereby the initial upwardly bowed shape minimizes outward swinging between opposed inner edges of the doors when in the closed position.

Abstract: A bracketing system is provided having two brackets joined by a flexible adhesive material that allows bridging or backing members of variable lengths and widths to be mounted between vertical studs to enhance stability of the wall construction. A wall construction assembly according to an embodiment of the invention comprises two vertical studs and a bridge backing member mounted there between by a bracketing system, which includes a left bracket and a right bracket connected by a flexible adhesive material. Because the bridge backing member can be adjustably sized to be secured on the brackets, it can be sized to fit between studs regardless of any variation in the spacing of the studs. This obviates the need to prefabricate bridge backing members to fit between variably spaced studs. The bridge backing member can be mounted flush with the stud to eliminate unevenness in the wall structure. Bridge or backing members of various widths and lengths can be mounted to the bracketing system.
