MOLDING BASE FOR MANUFACTURE OF REINFORCED-CONCRETE PRODUCTS ON LONG BEDS Russian patent published in 2002 - IPC

FIELD: manufacture of building products, in particular, heat treatment of concrete and reinforced-concrete products on long beds. SUBSTANCE: the molding bed has a stiff reinforced-concrete slab, heating element and metal plates, successively placed on the reinforced-concrete slab are heatinsulating material of a layer of foam concrete and stiff mineral wool plates, each enclosed in a water-proofing envelope, for example, of polyethylene, concrete covering placed on whose surface in a wave-like manner is the heating element in the form of an electric heating cable with a wavelength of 2-3 m, amplitude of 0.1-0.2 m, and the distance between the cables and the plate edges equals 48-52 mm, and 88-92 mm in the middle of the plate, layer of fine-grained concrete and metal covering plates. EFFECT: saved heat and created favorable heat-moisture conditions. 1 dwg
