OPTIMIZED LEVELING DIG FOR CONCRETE SLABS

Abstract

The invention relates to a leveling gauge (1) for the creation of a concrete screed made on a substrate, said leveling gauge (1) comprising a rod (2), a base (3), located in the lower part of the rod (2) and intended to come into contact with the substrate, the rod (2) being integral with said base (3) and a level indication member (4), movable along the rod (2) and held on the rod (2) at any height along said rod (2) so as to constitute a visual reference of adjustable height. According to the invention, the rod (2) has a cylindrical shape, one end of which has a thread (2a) engaged by screwing into a tapped hole (6a) provided in the base (3), the level indicator member having at least one retaining clip (5, 16, 12, 14) elastically deformable to allow engagement on the rod (2), sliding and holding in position of the level indicator member (4) on the rod (2).Figure for the abridged version: Fig 1.

Claims

upper end, a target (25) intended to cooperate with a light or laser beam to constitute the visual height reference for the height adjustment of the leveling rod (1).

15. Leveling pin (1) according to any one of claims 1 to 14, characterized in that the base (3) has an extension (24) transverse to the longitudinal axis (L) of the rod (2), intended to be in contact with the substrate and to be held against the substrate by the foot of the operator during the placement and height adjustment of the visual reference of the leveling pin (1). 6a [Fig. 4] [Fig. 5] [Fig- 7]
