Total Claims: 2
Claim 1
Independent Claim 267 words
Apparatus for the manufacture of reinforced concrete buildings open on one side, in particular prefabricated ferroconcrete garages comprising: inner and outer moulds intended for use in a pit below ground or floor level; a frame upon which the building is moulded and against which the open front of the building rests, said frame establishing means by which the moulded building can be lifted from the moulds; the outer mould comprising mould panels; a fixed mould scaffolding having a vertical part and a horizontal substructure beneath said frame for supporting same; guide link means articulating the mould panels to the said vertical part of the mould scaffolding for moving said panels toward and away from said frame; drive means operative in the plane of the guide link means to withdraw the mould panels from the moulded building; presses between said horizontal substructure and said frame for the building for releasing the attachment of the building to the inner mould so that it can be raised by means of a lifting appliance; a rigid rectangular mould core constituting the inner mould; rigid mould panels on two opposite sides of said core; said rigid mould panels tapering inwardly from bottom to top to enable separating the moulded building therefrom; mould panels on the other two sides of said core movably mounted for movement away from the moulded building; the bearing of each such movable mould panel consisting of pairs of guide links; mutual hinges for said links; and a tiering attachment movable parallel to the plane of the panels between said panels and the mould core for operating said hinges.
