The spacer for reinforcement elements of concrete structures has a profiled load-bearing member (1) onto which a number of supports (6) are plugged. Each support (6) is of an A-shaped design in side view and has, in its upper part, a transverse web (7) in order to form a plug-through opening (8) for the load-bearing member (1). The load-bearing member (1) has a double-T profile having a web (2), at the foot end of which there is arranged a relatively wide foot beam (3) and on the upper half of which there is arranged a transverse beam (4) having a somewhat longer length than the inside width of the plug-through opening (8) at this point, and the head end (5) of which serves as bearing surface for the reinforcement elements. A spacer of this type has a high degree of stability and can be produced with a relatively low amount of outlay and material. Moreover, the upper part of the support serves as a stop for the accurate laying of the reinforcement elements. <IMAGE> |
