Abstract
Abstract The element moulding consists of metal mesh and contains prepunched perforations. These perforations for the introduction of reinforcing bars are arranged in a row parallel to the longitudinal edge of the element moulding. When concreting the first stage the element moulding is buttressed unilaterally with wooden support elements. Before commencing the concreting of the second stage the wooden support elements are removed. The element moulding is used as sunken shuttering for both stages of the concrete structure. The erection of element moulding shuttering is easy and effortless; the bonding of both stages flawlessly effected.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
168 words
Apparatus for use in a two-stage concrete pouring construction process such as pouring floors or ceilings for buildings, comprising: a horizontal shuttering; an element moulding for use as a sunken shuttering comprising a rigid profile metal mesh on said horizontal shuttering, said mesh having two longitudinal edges; a plank liner arranged between the metal mesh and the horizontal shuttering for spacing the mesh from the horizontal shuttering, said plank liner being removable before the concrete pouring of the second stage; a plurality of horizontally oriented reinforcing bars; perforation means in said element moulding for introducing the plurality of horizontally oriented reinforcing bars, said perforation means being disposed in two parallel lines, each line laying near one of the two longitudinal edges of the element moulding; and support means for laterally buttressing the element moulding metal mesh on one side and to be fixed to said horizontal shuttering before the introduction of the concrete pouring of a first stage, and removable before the concrete pouring of the second stage.
