Abstract
The invention provides a device for forming joints in a floor or pavement, generally made of concrete. The device includes a guide bar and assembling members, having oblique legs forming an inverted V. The summit of the inverted V has a part rising from it in the form of a crest with vertical sides and a horizontal edge. The guide bar has a profile with a lower part which has the shape of a two legged clamped-nail, each of the legs of the clamp-nail having on their internal side, at some distance down from the summit of the clamp-nail, a boss forming a locking means for holding together the guide bar and the assembling members when said guide bar is placed astride the crest of an assembling member.
