摘要:
A sectional nog structure for fastening a covering element to a foamed plastic slab (5, 6, 35, 39, 49, 54) comprises at least one insert (2, 3), flush-insertable in the slab (5, 6, 35, 39, 49, 54) and associated with a tierod (4), having a base (10) accessible from the outside of the slab and constituting respective means for fastening to the slab (5, 6, 35, 39, 49, 54) the chosen covering element. Advantageously, this sectional nog structure allows to manufacture composite and modular construction elements, such as for example lost formworks and panels incorporating at least one foamed plastic slab and being able to support any covering element.
摘要:
Un élément modulaire composite pour des constructions comprenant généralement un corps en matériau synthétique expansé est muni de panneaux de revêtement (9,10) préformés sur les deux faces externes opposées de l'élément modulaire. Les panneaux de revêtement peuvent être formés au chantier en coulant et en rasant un mortier de ciment de préférence renforcé à l'aide de fibres sur un "coffrage" composé d'un bord périmétral (6) formé sur la face du corps de résine expansée et sur laquelle se trouve également un sillon périmétral à l'intérieur de ce bord, ainsi qu'une série de sillons transversaux pour donner naissance à autant de nervures (11) du panneau de mortier de ciment formé, lequel assume des propriétés portantes intrinsèques. Les éléments modulaires peuvent être posés sans étriers de soutien, en vertu de leur poids et de leurs capacités portantes et les panneaux d'une façade sont unis de façon permanente en "consommant" à l'aide d'une torche thermique la résine expansée des bords le long des lignes de jonction entre les éléments posés et en remplissant les fuites ainsi créées au mortier, en rasant la surface de la façade externe.
