Ceiling panel of a large surface area necessary after assembling the form of several elements of the ceiling in concrete weapon prefabricated and method of manufacture of such elements of the ceiling and the ceiling panel

摘要

P the invention relates to the panels of ceilings of large surface area necessary, after assembly. / p & & p & is constructed, the ceiling panel from ceiling elements 1 in which are made of the channels 2 extending longitudinally closed at their base, but which opens towards the top, channels which are interrupted by the ribs 3 and in that the vertical oblong holes 7 are provided in these ribs. The ceiling elements are juxtaposed in such a way that their channels are connected between them. There are threaded the cables of stress in a straight line in the channels, after which it is possible to give them a voltage surge by bending in the channel open at the locations necessary (by pulling downwards) without difficulty. The cables thus surtendus by bending are fixed by the concreting of the channels. / p & & p & application to the embodiment of the ceiling panels which can reach 40 to 80 m * * 2. / p
