Wedge set, especially for use in fastening floor joists

Wedge set, comprising:

• first and second interslidable wedges adapted to abut each other along cooperating first and second abutment surfaces respectively;
• third and fourth abutment surfaces extending substantially parallel to each other and respectively forming first and second acute angles with the first and second abutment surfaces;
• a rib attached to the first abutment surface;
• a groove formed on the second abutment surface;
• a plurality of teeth formed on opposing sides of the rib and a plurality of pawls formed on opposing sides of the groove, the teeth and pawls being adapted for retaining the first and second wedges in a mutual displacement so that the distance between the third and fourth abutment surfaces is reduced;
• and
• first and second longitudinal webs on opposing sides of the first abutment surface and first and second outwardly protruding projections on opposing sides of the second abutment surface, the first and second longitudinal webs and the first and second outwardly protruding projections adapted for retaining the first and second abutment surfaces in abutment with each other,
• wherein the teeth and pawls form a plurality of ratchets.
