Patent number: 4785600Abstract: 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.Type: GrantFiled: February 16, 1988Date of Patent: November 22, 1988Inventor: Raymond M. L. Ting

Patent number: 4741134Abstract: A composite metal/concrete floor system and method of installation. The system includes a novel decking profile; snap-in cover plates to provide longitudinal cells for three services; a lateral trench with sheet metal rails and bottom plates; and cooperating preset inserts. The deck and cover plate may be used as distribution cells suspended between the bar joists of a formed deck.Type: GrantFiled: October 22, 1985Date of Patent: May 3, 1988Assignee: Consolidated Systems, Inc.Inventor: Larry A. Stohs

Patent number: 4697399Abstract: A deck structure is disclosed in which overlapping and interlocking corrugated members, each formed from a single sheet of metal, are covered with a layer of concrete. Each corrugated member has at least one longitudinally extending valley along one side and a substantially flat flange provided on an opposite side. The flange may include spaced-apart longitudinally extending shallow depressions spaced at a distance and configured to receive and interlock with an adjacent member. When the decking is used as a deck form, the end portions of the sheet members may be partially or completely closed. Perforations which may be provided in flange portions of the members, allow water and other liquids to drain through deck form and to be caught in a vented valley portions of an adjacent member.Type: GrantFiled: January 17, 1986Date of Patent: October 6, 1987Assignee: Cyclops CorporationInventor: Thomas G. Ryan

Patent number: 4630414Abstract: 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.Type: GrantFiled: June 7, 1985Date of Patent: December 23, 1986Inventor: Raymond M. L. Ting

Patent number: 4529051Abstract: A scale assembly includes a plurality of force measuring transducers which are connected with an improved platform. The platform has an upper portion which withstands compressive stresses and a lower portion which withstands tensile stresses during the weighing of a load. The upper portion of the platform includes a body of concrete having a corrugated lower major side and a flat upper major side which receives a load to be weighed. The lower portion of the platform includes a metal structure having a plurality of elongated ribs which are disposed in abutting engagement with the corrugated lower major side of the body of concrete. The ribs are connected with a bottom plate which cooperates with the ribs to form elongated cavities. At least a major portion of each of the cavities is disposed within the spatial envelope of the body of concrete to minimize the mass of the concrete.Type: GrantFiled: September 19, 1983Date of Patent: July 16, 1985Assignee: Masstron Scale, Inc.Inventors: Ronald D. Stolz, Benny N. Dillon, Frederick H. Weihs

Patent number: 4507901Abstract: A sheet metal structural shape for use as a stud or mullion in wall construction or a purlin or sub-purlin in deck construction which is symmetrical about a vertical bisecting plane having a central vertical web, two diagonal legs projecting downwardly from one end of the web forming an included angle of about 30.degree. to about 90.degree., each of the diagonal legs having a leg projecting downwardly at its extremity in a plane substantially parallel to the web, each of the parallel legs having flanges extending outwardly at their extremity, a closure side extending between the extremities of the flanges enclosing the area formed by the diagonal sides, parallel sides and closure side, and a stiffening member at the other end of the web. A wall structure utilizing a spaced series of the metal structural shapes with a wall material attached to the flanges of adjacent structural shapes.Type: GrantFiled: September 19, 1978Date of Patent: April 2, 1985Inventor: Frank E. Carroll

Patent number: 4457115Abstract: A poured concrete deck structure which extends to the external building line or to a designated line of an internal opening of a building has a form deck which is supported by metal structural girders, including edge girders which are spaced from the building line or designated line, and an edge construction which retains the concrete according the building specifications. The edge construction is improved by terminating the form deck at the edge girders, providing a plurality of spaced support means secured to the top of the edge girders and extending towards the building line or designated line and providing a plurality of adjacent pans for retaining the poured concrete. The pans are supported by at least two supports, and are in communication with an edge girder. The pans may be secured to the edge girder, to the support means, or to both, after proper alignment with the building line or designated line.Type: GrantFiled: July 27, 1981Date of Patent: July 3, 1984Assignee: Multuloc CorporationInventors: Kenneth R. Grearson, Robert Watson, Jr.
