A wedge set for use in fastening floor joists consists of two interslidable wedge members (1, 2) adapted to abut each other along cooperating first abutment surfaces (3, 10), each wedge member (1, 2) having a second abutment surface (4, 11) forming an acute angle with the corresponding first abutment surface. The second abutment surfaces (4, 11) on the two wedge members (1, 2) of the wedge set extend substantially parallel to each other. The wedge members (1, 2) have cooperating locking means (6, 7, 13, 14), which are adapted for retaining them from a mutual displacement so that the distance between their second abutment surfaces (4, 11) is reduced, and retaining means (9, 15), which are adapted for retaining the first abutment surfaces (3, 10) in abutment with each other. The first abutment surfaces (3, 10) are plane and the locking means (6) consist of ratchets. |
