Abstract: A prefabricated steel frame building structural system which is assembled with nuts and bolts and required no shop welding or site fabrication. The columns and beams in the building are fabricated from lengths of very high strength, light gauge, stiffened C-channel steel stock. Uniquely designed haunch plates and haunch plate stiffener angles are used for column-beam connections and novel ridge plates and ridge plate stiffener angles are used for beam-beam connections to form the two hinged end wall and intermediate frames for the building. Also used are novel corner girt clips for securing the girts to the corner columns; rake purlin angles for securing purlins to the rake beams; and purlin girt clips for securing purlins to the intermediate beams and for securing girts to the intermediate columns. Each of the mentioned components are designed so that they may be used interchangeably at both the left and right sides of the building, there being no specially designed left and right said components.

Abstract: Walls and partitions are constructed by securing of wallboard panels to a substructure, such as common wood or metal framing members, by a series of concealed clips of described construction, affixed to the framing members by nail or screw type fasteners. When the wall or partition is erected the fasteners are hidden from view so that joint treatment of the wallboard panels may be reduced or eliminated, depending on the type of wall structure constructed. The side or edge gripping clips are impaled along each side of abutting panels. When erected, a first series of clip fasteners are impaled on a side of a first wallboard and fastened to a framing member and a second series of such fasteners are impaled on an abutting or nearly abutting side of a second, wallboard panel, offset from the first series of clips so as to fit behind and be held by the first panel in a "tongue and groove" type cooperation.

Abstract: A fire rated, demountable partition structure is disclosed which provides H-shaped studs having a core of combustion-resistant insulation material and opposed channel-shaped metal members secured to opposite faces thereof. Spline clips secure one side of the stud to the panel at joints therebetween. Each clip includes a lateral projection extending with a close fit into a kerf in the edge of the panel and a reverse bend providing opposed clip walls which fit along opposite sides of an adjacent flange on the stud. If the partition is exposed to a fire or the like, which tends to cause shrinkage of the panels and opening of the joints, the core of the stud bridges the joint and prevents direct exposure of the metal channel elements of the stud to heat or water through the opened joint. The spline clips are free to expand if the clips are subjected to greater heat than the channel members so that the stud is not caused to bow toward the fire side of the partition.

Abstract: A series of rectangular roof panels and rectangular wall panels each include inner and outer corrugated sheet metal skins or skin portions which are rigidly secured by fasteners to opposite sides of formed sheet metal longitudinally extending spacer members rigidly connected by formed sheet metal laterally extending spacer members.

Inclined inner eave attachment plates or panels rigidly connect the skin portions of the roof and wall panels, and other eave attachment members rigidly connect the roof panels and wall panels to form a building structure which has substantial total strength and may be easily and quickly erected without the use of a crane. Each of the roof and wall panels is prepunched and may be formed from a single metal sheet which has a single major corrugation or a Z-shaped lateral configuration.

Abstract: Mechanically held fasteners or clips invisibly secure common end-abutting wallboard panels to common wood or metal framing members. The fasteners are spaced apart, extending from the backs of wallboard panels and beyond their vertical ends so as to be conveniently screw fastened to a framing member. When screw fastened to common wall framing members, the clips, due to their spacing structure, which also improves clip strength, secure the wallboard panels slightly off the framing member front surface to permit offset fasteners of abutting wallboard panels to slide between the fastened wallboard panels and the framing members and to be engaged by the fastened wallboard panels in a "tongue and groove" relationship, preventing transverse panel movement.

Abstract: An extruded metal construction stud for use within a multitude of different interior room wall systems is disclosed as comprising a substantially U-shaped structure defined by means of a base web and a pair of perpendicular sidewalls. Each of the sidewalls is substantially S-shaped in configuration, and the corresponding parts thereof are reversed such that the sidewalls are, in effect, mirror-images of each other. Each of the sidewalls defines a pair of oppositely facing open channels integrally connected by means of a common flange. One of the channels is open to the exterior of the stud and accommodates edge portions of wall board panels. Flanges of the channels separate from the common flange serve to define support surfaces for wall board panels as do laterally outer portions of the sidewalls. The different wall systems are able to be expeditiously erected by incorporating one or more of the construction studs within the particular wall structure in a variety of different modes.

Abstract: A wall construction of the type having horizontal sole plates which are attached to a foundation and a series of vertical studs which extend from the sole plates can be improved by constructing a building or other structure using individual modular sections for the wall construction. Each of the individual modular sections has a sole plate which is attached to or otherwise fastened to the foundation or other supporting structure. Resting on top of and attached to each end of the sole plate is a vertical end stud. Traversing across the top of the end studs is a singular top plate. The end studs are perpendicular to the sole plate and the end studs; the sole plate and the top plate all lie in the same plane. Extending between the top plate and the sole plate and placed a unit distance away from each end stud is a vertical interior stud. Depending upon the length of the modular section additional vertical interior studs are also symmetrically spaced between the end studs.

Abstract: Mountings for detachably connecting juxtaposed edges of at least two wall panels that radiate from the mounting are described wherein a jaw member is formed with two jaw surfaces that engage faces of the panels on one side of the panels close to the edges. The two jaw surfaces are spaced apart and an intermediate part either formed in one piece with the jaw member or fixed thereto, is located between the jaw surfaces and between the edges of the panels. The panels are maintained in contact with the jaw surfaces by two further such surfaces on a jaw device engaging faces on the opposite side of the panels. This jaw device is formed with a recess that fits onto the intermediate part and determines the extent of separation of the opposed jaw surfaces. At least one screw fixes the jaw device to the intermediate part. The location of the jaw surfaces determines the angle at which the panels are set relatively to one another.
