Abstract
A decking clamp for use in an underhung roof system. A C-shape housing has opposed arms and a variable gap opening in a clamping cavity. A threaded retention nut is secured within two opposed slots in a front section of one of the opposed arms rearward of a partition wall. The retention nut will not fall out of the housing during use by an installer.
Claims3
A decking clamp for use in an underhung roof system comprising:
- a substantially C-shaped housing having first and second opposed arms and a clamping cavity with a variable gap opening to said cavity;
- a threaded retention nut having an outer diameter dimension secured within a two opening notch in a front section of said first opposed arm;
- and
- a threaded fastener member extensible through said housing and said threaded retention nut, said fastener member rotatable through said nut to vary the width of said variable gap opening between said first and second opposed arms.

A method for making a decking clamp for use in an underhung roof system comprising the steps of:
- (a) providing a generally planar clamp template, said template further comprising:
- a transverse axis generally dividing said template into first and second sides and a longitudinal axis generally dividing said template into an upper section and a lower section;
- a first retention nut opening in said first side of said template and a second retention nut opening in said second side of said template, said first and second nut openings spaced equidistance from said transverse axis, and in said upper section of said template;
- a partition wall between said first and second nut openings;
- and
- a clamping cavity opening in a generally central section of said template, said clamping cavity opening having a shape symmetrical about said transverse axis of said template;
- (b) providing a threaded retention nut and a threaded fastener member;
- (c) initiation of folding said template along said transverse axis;
- (d) inserting said retention nut in said first and second nut opening and along a rear side of said partition wall while folding said template;
- (e) completing folding of said template into a C-shaped clamp until a side wall gap width of less than the diameter of said nut is achieved, said nut being securely retained in said nut openings and rearward of said partition wall;
- and
- (f) passing said threaded fastener member through a channel in an upper section of said folded C-shaped clamp and threading said fastener number through said nut until the head of said fastener member forms a gap opening in said cavity in said folded C-shaped clamp, said gap opening having a variable width corresponding to the distance of threaded movement of said fastener member through said nut.
