Title (EN) FRAMING FOR MAKING CONCRETE SLABS
(FR) ENVELOPPE COFFRAGE POUR LA FABRICATLON DE DALLES EN BETON
Abstract: front page image
(EN)The framing envelope consists in a double lattice the upper part (2) and lower part (1) of which are interlaced at the edges (3 and 4) of the envelope. The upper part (2) is connected to the lower part (1) along the edges (3 and 4), parallel to them, while forming several rectangular or square chambers (7). The chambers (7) are connected to at least one opening for the filling with concrete, and partitions (8) are provided in each chamber, which limit the bulging of the walls of the envelope. In order to keep, in a concrete slab made by means of this framing, the blocks surrounding the breakage zones interconnected after the envelope has been destroyed, reinforcing extensible threads (11) which are anchored at least in the lower part of the envelope are provided in this envelope. These threads extend throughout the concrete in a zigzag fashion.
(FR)L"enveloppe coffrage consiste en un treillis double dont la partie superieure (2) et la partie inferieure (1) sont entrelacees au bord (3 et 4) de l"enveloppe. La partie superieure (2) est reliee a la partie inferieure (1) parallelement le long des bords (3 et 4) en formant en plan plusieurs chambres (7) rectangulaires ou carrees. Les chambres (7) sont reliees a au moins une ouverture de remplissage pour le beton et des cloisons (8) sont prevues dans chaque chambre limitant le bombement des parois de l"enveloppe. Afin que dans une dalle de beton fabriquee a l"aide de ce coffrage les blocs entourant les zones de rupture restent relies entre eux aussi apres la destruction de l"enveloppe, il est prevu dans cette enveloppe des fils d"armature (11) extensibles qui sont ancres au moins dans la partie inferieure de l"enveloppe. Ces fils s"etendent a travers le beton en zigzag.
