Abstract: This invention relates to the wall joint design using composite wall panels each consisting of two metal facing skins sandwiched with a structural foam core. The sealing, stuructural performance, and fire performance of the panel sidejoint are significantly improved without compromising other functional performances. The vertical wall joint in horizontal panel application is improved with respect to sealing integrity, thermal insulating value, and easiness in construction.

Abstract: A building panel assembly comprising two or more individual panel members. The panel members in turn are comprised of an outer metal facing sheet forming an exterior panel surface, an inner metal facing sheet forming an interior panel surface and a structural foam core. Once the individual panel members are secured to a structural support, a foam plug is inserted between the panel members to enhance the insulated properties of the assembly.

Abstract: The vertically slidable connection mean for the erection of curtainwall mullion is assembled from a housing clip, a holding clip and two side fastening clips to provide easiness in depthwise, lateral, and rotational adjustments during erection. At the location of supporting the dead weight of curtainwall, a load bearing member is preinstalled below the regular slidable connection mean, thus a unified erection procedure for all connection points is maintained.

Abstract: This invention relates to the water-tight performance of an exterior wall panel system. Each individual wall panel consists of an exterior facing member and four perimeter extrusions. The design prevents the exterior water from reaching the wall joint seals eliminating water leakage without using an internal gutter system and water drainage mechanism is provided within the wall cavities which are pressure equalized to the exterior environmenal air.

Abstract: This invention relates to the construction of a composite beam structure in a composite steel deck floor system. A T-shaped beam is welded through the valleys of the steel deck onto the top flange of the supporting beam. After concrete pouring, the T-beam is buried within the concrete slab to act as the shear transferring device to achieve the composite beam action. The T-beam also serves to strengthen the supporting beam in resisting the load during the concreting operation and to facilitate the placement of the concrete shrinkage control wire mesh.

Abstract: This invention relates to the water tight performance of exterior panel wall systems erected in the horizontal mode. A water tight exterior wall system is accomplished by providing a pressure equalized chamber and a water drainage groove in front of the primary sealant lines without using an internal drainage system.

Abstract: A composite foam panel with an outer metal skin and an inner metal skin which sandwich a structural foam core. The thermal blistering problem, which is common to a composite foam panel is solved by this invention by using an internal gas venting system adjacent the inner surface of at least one of the outer skins of the panel.

Abstract: This invention relates to a composite wall panel structure consisting of two metal facing skins sandwiched with a structural core. The sealing and structural performances of the panel sidejoint are significantly improved. This invention is particularly useful for panels erected in the horizontal mode.

Abstract: This invention relates to a metal plate curtain wall structure. The joints of the metal plate structure are sealed weathertight without exposed caulking. A second line defense against water infiltration is formed by a concealed internal drainage system without exposed weep holes eliminating the water stain problem under the weep holes and enhancing the architectural appearance.A plate connection system securely fastened to the structural support is slidable in the direction parallel to the plate surface allowing free thermal expansion of the plate without weakening the resistance against wind load acting normal to the plate surface. The connection system is also designed to absorb any conceivable dimensional tolerance of the support frame facilitating the easiness of field erection.

Abstract: Cellular steel flooring is provided which includes corrugated steel decking and separately applied cover plates which establish a lengthwise cell in cooperation with a valley and the two connecting sloping sidewalls. The resulting cellular steel decking permits distribution of electrical wiring or ventilation air throughout a building without requiring perforations or penetrations of the crest surfaces or sloping sidewall surfaces of the decking. The resulting wet strength of the cellular steel decking remains undiminished. The exposed corrugated undersurface of the corrugated steel decking provides an improved adhesion surface for subsequently applied fireproofing materials. Special cover plates for noncellular troughs are provided along the locus of transverse electrical trench structures to facilitate the mounting of the electrical trench and to permit strengthening concrete to be applied beneath the electrical trench.

Abstract: Improved corrugated steel decking of the type having plural crest surfaces, plural valley surfaces and plural sloping web surfaces connecting each crest surface to the adjoining valley surface. An inwardly depressed groove is provided in each of the sloping web surfaces adjacent to the crest surface.

Abstract: An improved double skin metal wall liner for a building formed from spaced-apart structural liner panels and interposed non-structural liner panels. The non-structural liner panels are formed from sheet metal having less thickness than the structural liner panels. Both panels are secured to a building framework and to each other. The outboard ends of the structural liner panels comprise mounting surfaces for fastening an outer facing wall for the building.

Abstract: A building wall construction employing liner panels and facing panels. Liner panels are positively secured and releasably secured between adjacent horizontal frame members of the building. Facing panels are positively secured at their mid-region to a horizontal frame member and are positively secured at one end to a liner panel and releasably secured at the other end to a liner panel. The resulting building wall will fail at predictable pressure differentials.

Abstract: A thermally insulated wall panel for building construction having a metal liner panel and a metal facing panel with interconnected side-joint profiles which provide positive connections of facing panels of adjoining wall panels when outward stress is applied. Positive connections of the liner panels of adjoining wall panels can be obtained when outward stress is applied.

Abstract: A pad adapted to sustain an impact load by stepwise absorption of kinetic energy. The pad incorporates a collapsible, i.e., crushable core adapted to undergo stepwise deformation under the force of the impact load. Stepwise deformation of the core provides, during impact load application, a significant lowering of the peak dynamic load sustained by the pad and applied to the pad support. The normally encountered high buckle-initiating peak loads are entirely avoided by the present pad.

Abstract: A fastening device for securing adjacent double-skin foam-core wall panels to the structural framework of a building. One panel has a channel formed in the outer skin which extends laterally inwardly of a gap presented between the adjacent edges of the inner and outer skins. The adjacent panel has a tongue formed along the outer skin which is engaged in the channel. The fastening device includes a clip member and a fastener. The clip member has an edge strip engaged with the channel, a flange penetrating the core terminating proximate to the inner skin, and a medial strip connecting the edge strip to the flange. The medial strip is offset from the plane of the edge strip to provide space for the head of the fastener. The fastener extends through the medial strip, the core and the inner skin and secures the panel to the subgirt. The clip member may be mechanically connected with the channel to increase the suction load resistance of the joint.

Abstract: A controlled release wall structure is provided which relies on controlled strength distribution and which disengages from a building framework at a selected applied load -- failure load -- and collapses in the direction of the applied load, that is, inwardly or outwardly of the building. Under normal wind load conditions, the present wall structure will safely sustain the expected elastic deflection and working stresses. However, under abnormally high loadings such as applied by explosion forces or by tornado and hurricane wind forces, the present wall structure collapses to create a substantial open area whereby a minimal loading is transmitted to the structural framework. The present wall structure protects the building framework from being overstressed during tornadoes or hurricanes; and also is capable of quickly relieving excessive pressures generated by an explosion within or without the building.

Abstract: A non-composite impact-resistant structure of lightweight construction is particularly useful in offshore power stations where weight is a prime consideration, and also is useful as the roof of inland power stations. The structure is fabricated from two types of sheet metal units and reinforcing elements which are enclosed thereby. An inner cellular panel is secured to outboard members of a building framework. The cells of the inner cellular panel extend vertically or horizontally when used as a wall structure or may reside in a generally horizontal plane when used as a roof structure. Outer corrugated panels (or outer cellular panels) are secured outboard to the inner cellular panel with the corrugations (or cells) of the outer panel perpendicular to the cells of the inner panel. The inner cellular panel cooperates with the outer corrugated panels to define passageways providing peripheral metal enclosure for reinforcing elements.

Abstract: An impact-resistant wall structure is fabricated from two types of sheet metal cellular panel units and concrete columns which are enclosed thereby. Inner sheet metal cellular panel units are secured to outboard members of a building framework. Outer sheet metal cellular panel units are secured outboard to the inner sheet metal cellular units with the cells of the inner units perpendicular to the cells of the outer units. The inner sheet metal cellular units cooperate with the outer sheet metal cellular units to provide total peripheral metal enclosure for concrete columns. The outer sheet metal cellular units are fastened to the inner sheet metal cellular units at contiguous points preferably by means of threaded fasteners which extend into the concrete columns. Reinforcing rods positioned within the cells of certain or all of the panel units provide increased tension reinforcement, increased shear resistance, and produce local damage to impacting missiles.

Abstract: A wall structure of the double-skin insulated type which spans across at least first and second building frame members. The wall structure comprises a liner sheet positively secured to the second frame member and having a liner sheet end lapping the first frame member; confinement means releasably retaining the liner sheet end to the first frame member; a facing sheet positioned outboard of the liner sheet; and at least two subgirts (a) entirely spaced-apart from the first frame member in the direction of the second frame member and from each other, (b) positioned between the facing sheet and the liner sheet, and (c) each secured to the facing sheet and to the liner sheet.The arrangement is such that the wall structure fails in a particular manner when subjected to abnormally high positive or negative wind pressures of preselected value. The failure load of the wall structure is controlled by the end-subgirt spacing -- the distance between the first frame member and the subgirt adjacent thereto.
