Patent ID: 7866114

Claim:
A device to separate or space out metallic structural elements for reinforcing concrete from each other and from the surface on which the concrete is going to be poured, wherein the device is formed by two opposite vertical walls joined to one another by a third transverse vertical wall, and a horizontal reinforcing surface dividing the device in an upper section for receiving the metallic structural elements and a lower section with a plurality of support legs; each one of the opposite vertical walls presenting a semi-circular cavity on their upper edge formed to receive a metallic structural element to be supported; and in its lower part, each one of the two opposite vertical walls is divided into two legs defined by outside edges of the vertical walls and an arched cavity between them, and a third intermediate leg is formed by a projection of the third transverse vertical wall; the third transverse vertical wall extending upwardly to the lowest point of the semicircular cavities, where the upper edge of the third transverse vertical wall supports the structural element as well; the load of the structural element being distributed along the upper edge of the third wall, as load axis, toward the vertical walls of the device, and is finally concentrated on the contact surfaces of the three legs.
