Ladder shaped spacer for cast concrete wall construction, has posts including sections co-operating in longitudinal sliding relation with profiles of rails of panels and setting plane of ladder orthogonal to planes of panels, respectively

摘要

The spacer (1) has two parallel posts (10) connected by two cross pieces (11) that are perpendicular to the posts, where the spacer is made of thermoplastic synthetic material. The posts have profile sections co-operating in longitudinal sliding relation with profiles of stiffener rails (4) of panels (2, 2') and setting a plane of the ladder orthogonal to planes of the panels, respectively. Each post has a groove (12) with a shape complementary to a wing (6) and a wing return unit (7) of the corresponding rail, and forming a stop non-parallel to the plane of the ladder.
