Building structural system

Claim 1

A building structural system comprising, a plurality of preformed elongate structural elements positionable in both angular and parallel interrelation with adjacent parts of elements in abutting relation, said elements including a sill element, a plate element, and a plurality of vertically extending stud elements each having a lower end directly engaging and supported by said sill element to define the basic wall frame of a building, each of said elements being of metal sheet material and having a box cross-section with a full width planar panel, a pair of planar panels in spaced parallel relation to said full width panel, and a pair of interconnecting planar panels, each of said planar panels having a series of uniformly spaced-apart fastener-receiving and locking devices and with each of said devices being comprised of a pair of flanges deformed from the planar panel to extend angularly toward each other with closely adjacent free ends and define a narrow elongate slot for receipt of a fastener, all of said series of devices having the same spacing between devices and all of said series of devices being uniformly interrelated to have a device from each planar panel at the same location lengthwise of the structural element, said plurality of stud elements having their interconnecting panels in a common plane with said interconnecting panels of said sill and plate elements to place a plurality of said fastenerreceiving and locking devices on the interconnecting panels of the stud elements, sill element and plate element in said common plane, and a plurality of members of different shapes interconnecting said elements in the desired interrelation and each having fasteners in the form of integral planar tabs extending therefrom and inserted into the slots of several ones of said locking devices and held against removal by said pairs of flanges, each of said planar tabs having a width substantially equal to the length of said slot to avoid play therebetween lengthwise of said slot.
