Abstract
Building frame elongate structural elements are provided having at least cavity which in transverse cross section has a mouth permitting access to said cavity, defined by a pair of opposed flanges which have first portions extending toward each other across the mouth and second portions extending inwardly of the cavity from said first portions and terminating at free edges so as to leave to each side of the mouth an undercut space which is behind the first portion and laterally outside the second portion, the said second portions of the flanges being deformable. Fixing members for combining said structural elements are also provided. The fixing members and structural elements are useful in making building frames from a plurality of the structural elements.
Claims10
A fixing member for a building frame elongate structural element having at least one cavity which as seen in transverse section has a mouth permitting access to the cavity, defined by a pair of opposed flanges which have first portions extending towards each other across the mouth and second portions extending inwardly of the cavity from said first portions and terminating at free edges so as to leave to each side of the mouth an undercut space which is behind the first portion and laterally outside the second portion at that side, the second portions of the flanges being deformable by bending laterally, said fixing member having a body and a cap which has opposite end portions directed towards the body with respect to a central portion, the cap in a first position being insertable into the said cavity of the structural element and being rotatable after insertion from said first position to a second position in which said end portions lie behind said flanges of the structural element, and the fixing member further having means to urge together the body and the cap when the cap is in the second position so as to clamp said flanges, and the body and the cap being so shaped, as to deform at least one of said flanges by bending laterally during the clamping thereby securing the fixing member to the structural element in a manner inhibiting slippage along the structural element.
In combination, a building frame elongate structural element having at least one cavity which as seen in transverse section has a mouth permitting access to the cavity, defined by a pair of opposed flanges which have first portions extending towards each other across the mouth and second portions extending inwardly of the cavity from said first portions and terminating at free edges so as to leave to each side of the mouth an undercut space which is behind the first portion and laterally outside the second portion at that side, the said second portions of the flanges being deformable by bending laterally, and a fixing member having a body and a cap which has opposite end portions directed towards the body with respect to a central portion, the cap in a first position being insertable into the said cavity of the structural element and being rotatable after insertion from said first position to a second position in which said end portions lie behind said flanges of the structural element, and the fixing member further having means to urge together the body and the cap when the cap is in the second position so as to clamp said flanges, and the body and the cap being so shaped, as to deform at least one of said flanges by bending laterally during the clamping thereby securing the fixing member to the structural element in a manner inhibiting slippage along the structural element.
