摘要:
The present invention relates to an industrialized construction process of at least part of a structure (1) to be constructed, by applying it, for example, to bridge decks, in which the filling material (8) is poured in situ on empty segments (3) prefabricated ex situ. The construction process according to the present invention comprises the prefabrication of empty segments (3) including the assembling of steel reinforcement elements (9) and assembling fixing elements (4) whereby these comprise rigid elements (22) and at least part of the moulds (13), which occur at a location (5) ex situ, for example at the factory, construction site or at a place close to the works front line; transport and placement of the empty segments (3) in the final position in the structure (1); the operation of pouring the filling material (8); consolidation or curing of the filling material; prestressing the structure (1), if applicable; removal of the moulds (13) and fixing elements (4); followed by the start of the next cycle, if applicable. The present invention also relates to a construction system adapted for carrying out a construction process of a structure (1) to be constructed.
摘要:
A mould for constructing a protection and securing element of the mattress type comprises an upper frame (10), a lower frame (30) and a plurality of dies engaged in the lower frame and particularly suitable during use for receiving cement material. The upper and lower frames are modular structures which each comprise a plurality of carrier elements which are selectively connected to each other, the number and/or length of the carrier elements being variable, during use, so as to vary the length and/or the width of the mould.
摘要:
A wound construction form (10) comprising a plurality of flexible sheet material layers wound one upon another about an axis and bonded together to form a tube, wherein all of the flexible sheet material layers comprise transparent polymer film. The tube thus is transparent such that a settable composition (20) poured into the tube can be seen through the tube wall. If an air bubble is present adjacent the wall, it can be eliminated while the composition is still fluid by puncturing the wall with a small hole at the bubble so that the air can escape and the composition can fill the void.
