An apparatus for molding a continuous foamed plastics element (2), such as a floor construction member of the type comprising a substantially parallelepipedic central body (3) and at least one lateral projection (5,6), includes a mold (13) comprising a forming chamber (13a) and a stabilization chamber (13b) defined between a bottom wall (22), a pair of opposite side walls (20,21), and a cover (23). Advantageously, the cover (23) and/or one or both the side walls (20,21) of the mold (13) comprise a plurality of structurally independent segments which may be adjustably positioned toward and away from the bottom wall (22) of the mold (13) for independently adjusting, in a substantially continuous manner, the height of the molding seats of the central body (3) and/or of the lateral projection (5,6) of the continuous element (2) in each of the forming (13a) and stabilization (13b) chambers of the mold (13).
摘要:
Un panneau composite (1) adapté notamment au domaine de la construction est doté d'un cadre (4) structurel en bois porteur de charge et formé par un corps parallelipipédique en matériau synthétique expansé ayant une épaisseur normalisée, une largeur normalisée modulaire et une hauteur adaptée à un usage particulier, lequel est conforme à la hauteur du plancher de l'immeuble à construire. Les panneaux présentent une pluralité de canaux longitudinaux s'étendant sur la totalité de la hauteur dudit panneau. Une série de canaux (2, 3) espacés et échelonnés uniformément dans le sens de ladite largeur et de ladite épaisseur du panneau sont ouverts sur la face adjacente de ce dernier et présentent une coupe transversale en forme de "T". Dans ces canaux ouverts s'adaptent des montants en bois (4) à coupe transversale en forme de "T", dont la partie de queue (4b) desdits canaux ouverts et est saillante à partir de la surface du panneau. La série de montants en bois en "T" échelonnés confère des capacités porteuses au panneau composite tout en formant des "nervures" orientées verticalement dépassant de la face du panneau en matériau synthétique expansé sur lesquelles on peut facilement appliquer une finition extérieure du mur.
摘要:
A composite article of manufacture for constructing concrete floors is completely factory assembled. The composite panel of the present invention comprises a body of expanded plastic having at least two parallel channels, open on the upper surface of the panel, that extend for the whole length of the article, adapted to be filled with concrete poured over the panel. A steel reinforcement bar fabric is installed into each channel. It may be composed of at least two parallel steel bars connected by at least an order of cross bars disposed at regular intervals along the length of the reinforcement fabric. At least same or preferably all the cross bars extend beyond a lowest reinforcement steel bar of the fabric for constituting a plurality of spikes of length sufficient to pass through the expanded plastic bottom of the accommodating channel in order to sustain in a stable upright position inside the channel the reinforcement fabric, and to protrude from of the underside surface of the expanded plastic body. One or more rolled or stamped sheet metal shrouds with at least one row of aligned holes spaced from one another at intervals identical to those of said array of protruding spike ends are applied to the underside surface of the expanded plastic body hung from the protruding ends of the spike by fastening nuts or caps stably engaged with the ends of the metal spike body reinforcement fabric, that cover the hole of passage of the spikes. The fastening nuts or caps may be of a sufficiently malleable metallic material capable of self threading on a helicoidal thread formed in the end position of the metal spikes or of a plastic material having a significant resistance to fire, such as for example a polytetrafluoroctilene or similar.

A composite construction element (1) is described comprising a body (2) made of expanded plastics material provided with opposite faces (8, 9) and at least one reinforcing section bar (10, 11), transversely extending in the body (2) between the faces (8, 9) and incorporated in the expanded plastic materials. The reinforcing section bar (10, 11) comprises a central portion (12) having at least one fin (13, 14) extending in a cantilevered fashion from the same and forming a longitudinal edge (15a, 15b) therewith and a plurality of openings (16, 17) at least partially formed in the central portion (12) of the section bar (10, 11) at the longitudinal edge (15a, 15b). Advantageously, the construction element (1) has improved self-supporting characteristics and improved characteristics of resistance to bending loads which it is subjected to during installation.
