摘要:
A top sheet and a bottom sheet are connected together by wing members, each having a center segment hinged to the top sheet and to the bottom sheet about parallel axes. Wings protrudes from the center segments and are biased to project out of a plane defined between the hinge axes. In a collapsed condition the top and bottom sheets are close together with the wings distorted from their relaxed positions. In the expanded condition the sheets are spaced apart and the wings return to their relaxed positions projecting out from the center segments and conferring stiffness on the structural member and resisting the return of the member to its collapsed configuration. In storage, the sheets are secured along the edges with an underlying rip cord, and may be rolled. The wings may be formed as part of metal or plastic spring members.

A pre-formed building panel comprising a metal core substantially completely encapsulated in a low density material and acting as a reinforcement member therein, that member comprising first and second sets of lengthwise-extending segments at different elevations within the panel and connected to adjacent segments of the opposite set by generally vertically extending segments, the panel optionally being provided at its side edges with portions adapted to be overlapped with corresponding portions of an adjacent panel, the panels being provided with metal edge plates at top and bottom, those edge plates optionally having a width less than the width of the panel, the general vertically extending segments being provided with relatively large holes spaced lengthwise therealong while the segments of the first and second sets are substantially free of holes, with the metal reinforcement member optionally carrying a vertical wall extending from a side edge of said member, the segments of said first and second sets, the edge plates and that vertically extending wall, if present, facilitating the attachment of external objects to the panel, an optional adapter plate fitting over the upper edge of the panel and having an inclined top wall to which roof elements and the like may be attached if desired.
摘要:
A monolithic construction of concrete reinforced with dispersed metal fibers having a bottom wall spaced from a top wall with each of the top and bottom walls having a top face generally parallel to an under face having a generally corrugated relief with alternating recesses and ridges extending in a substantially horizontal direction. A plurality of sidewalls extend upwardly from the bottom wall to the top wall and each sidewall has a generally overall corrugated cross section. An insulating foam panel covers the under face of each of the top wall and the bottom wall and there is a set of insulating foam panels between which each of the sidewalls is sandwiched, the insulating foam panels being the concrete formwork of the concrete structure.

A wall for making tanks includes two superimposed plates connected to each other at respective spaced apart connected points distributed on a surface of the plates, at least one of the two plates, between respective connecting zones, bulging outward, so that separation between the two plates increases in every radial direction with distance from each connected point to a maximum separation midway between neighboring connected points. The wall has a quilted appearance.
摘要:
A reinforced concrete deck structure particularly adaptable for bridge spans is made up of superimposed layers of concrete with a corrugated metal pan therebetween along with a plurality of reinforcing bars which extend transversely of and through the corrugations. Individual, partially completed slabs are precast and are then placed on a bridge span and covered with a second layer.
摘要:
A modular house is constructed with Engineered Structural Modular Units (EMSU's) made from Stucturally Engineered Oriented Strand Boards (SEOSB's). Unitized structures are formed from modular units comprising two SEOSB panels with internal webbing for floor, wall, ceiling and roof modules; and adapter units such as corner adapter units, U-channel adapters, alignment connectors, trim adapters, and roof support adapters. Window and door openings can be cut on-site during construction. Any insulation meeting local building code requirements can be installed on-site. Standard electrical, plumbing, and mechanical products and procedures can be used as required by local building codes. All roofing and exterior wall coverings that meet local building codes can be used as required by architectural design.

A stiffener system includes a stiffener and a fastener means. The stiffener includes an extruded body that includes a plurality of projections. The stiffener couples to the apparatus to facilitate increasing a structural integrity of the apparatus. The fastener means secures the stiffener to the apparatus.
摘要:
A lightweight panel construction in which a thin layer or veneer of gypsum board is laminated as a facing sheet onto a backing of lightweight open cell reinforcing material to form a composite panel that has the same surface characteristics and appearance as a sheet of conventional gypsum board and is suitable as a lightweight but strong substitute for conventional gypsum board. Portions of the open cell reinforcing material may be removed or omitted to form raceways or channels for utilities or the like.
摘要:
A corrugated structural metal plate includes longitudinally extending corrugations defined by alternating crests and valleys. Each of the crests and valleys includes longitudinally extending flat segments that are configured to reduce buckling of the plate when the plate is curved about an axis generally transverse to its longitudinal axis.
摘要:
A stiffening member, as well as a diaphragm of a building in which the stiffening member is used, is disclosed. The diaphragm includes a horizontal wide-flange beam, a corrugated deck, and a corrugated stiffening member. The stiffening member is an elongate, corrugated strip. The stiffening member's corrugations are formed by a series of U-shaped portions that alternate with, and are integrally connected to, a series of horizontal upper portions. Each U-shaped portion consists of three planar portions: two substantially vertical side portions and one horizontal floor portion. Each U-shaped portion is reinforced with two parallel raised ribs. In a second embodiment of the stiffening member, the U-shaped portion is reinforced with two parallel tab portions attached at the sides of the stiffening member. The stiffening member nestingly overlies the corrugated deck, and is attached to the deck and to the underlying horizontal beam with either welds or pins.
