Device for Forming shrinkage Joints in concrete works with Alternating elements in the Crack of ConcreteAnd they are constituted by trays mounted on linear Elements.

摘要

Provision for the formation of shrinkage Joints in Concrete Works constituted by a Plurality of trays of a material concrete separator mounted on Rigid linear elements of ManHe was responsive to either side of the line of surface crack on the top Face of the concrete surface and leaving gaps between them to allow cracking.The device facilitates the attachment of the adjacent slabs formed by the Board of retraction with consequent Improvement of the resistant behaviour.It is used in concrete works in situ such Earthworks, Roads, Canals, sewers, Tunnels, Railways, Dams and other.
