Spacers between two reinforcement layers
A spacer is inserted between the lower and upper reinforcement of a slab or the inside and outside reinforcement of a wall. It fixes the distance between the two reinforcement layers and keeps them in the structurally correct position during installation and concreting.
Basically, reinforcement spacers can be produced as flat lattice framework, which are bent out of the plane in the form of a sine curve, or they can be shaped in the form of a three-dimensional lattice cage. The former are called spacer strips, while the latter are continuous high chairs.
