Abstract: The method of manufacturing building bricks from an earth-based material, comprises:providing an open topped variable volume mold (140) whose bottom face is constituted by a piston (156);placing the open top of the mold under a feeder (95) for supplying earth-based compressible material;lowering the piston to a predetermined level to gravity load the chamber with a predetermined volume of material;displacing the mold transversely (204) relative to the loading direction until the said opening is closed by a compression plate;driving the piston (156) by means of a pressure-controlled jack (160) to compress the contents of the mold chamber to a predetermined pressure;displacing the mold transversely a second time to disengage the said opening from the compression plate, and raising the said piston by means of the said pressure-controlled jack to eject the compressed-earth product.

Abstract: A jointing device for long-limbed framework elements in reinforced concrete and framework comprising framework elements jointed by such devices.Means are provided for housing with a tightening fit the ends of the sections to be assembled. In a realization said means comprise a body from which depend at least two sleeves provided for housing with a tightening fit a portion of the sections to be assembled. The sleeves are preferably removably fixed to the body.
