Large reinforced concrete floor slab formwork template - has flat top of lattice girder, pierced by wire ends, integrally retained

摘要

The form beam, with the assembly seated on its underside at the bottom of a pit is used in prodn. of large reinforced concrete floor or foundation slabs, flattened on top by a skimmer board. Use is made of a lattice girder, with upper and lower chord and lattice structure. The girder has a levelled upper chord top as template, at the level of the intended slab top, remaining in the slab as integral component subjected to force flow. The girder has overlapping ends of the wires in the reinforcing mats or mesh passing transversely through it. The girder may be flat or triangular.
