Title (EN) ARRANGEMENT FOR LAYING CONCRETE FLOORS
(FR) DISPOSITION POUR LE COULAGE DE PLANCHERS EN BETON
Abstract: front page image
(EN)Arrangement for casting concrete floors against a hardened base with the aid of surface vibrators for levelling and vibrating the concrete. The arrangement consists of screed guides for these surface vibrators. The screed guides are designed in such a way that their cross-section is I-shaped. The upper horizontal surface serves as a slide face for surface vibrators (1). The lower horizontal surface series as a support against the base material (2). The beam web is provided with holes for dowels or other connecting devices (4). The beam web is also provided with brackets which can carry the reinforcement material for the concrete (3). The invention also includes reinforcing the above-mentioned beams by means of welded mesh reinforcement of metal and/or glass fibres. The latter can, but need not necessarily be, of alkali-resistent glass. The invention also embraces a method for using the above mentioned arrangement. This method entails using the beams as permanent formwork, i.e. the beam is not removed after the concrete has hardened.
(FR)Disposition pour le coulage de planchers en beton sur une base durcie a l"aide de vibrateurs de surface servant a niveler et vibrer le beton. La disposition consiste en des guides pour ces vibrateurs de surface. La section transversale des guides est un profile en forme de I. La surface horizontale superieure sert de face de glissement pour les vibrateurs de surface (1). La surface horizontale inferieure sert de support contre le materiau de base (2). L"ame de la poutre est pourvue de trous pour des goujons ou d"autres dispositifs de fixation (4). L"ame de la poutre est aussi pourvue d"agrafes pouvant supporter le materiau de renfort pour le beton (3). L"invention comprend aussi le renforcement des poutres decrites au moyen de mailles de renfort soudees en metal et/ou en fibres de verre. Ces dernieres peuvent, mais ceci n"est pas absolument necessaire, etre composees d"un verre inattaquable par les alcalis. L"invention decrit aussi un procede pour l"utilisation de la disposition decrite. Ce procede implique l"utilisation des poutres en tant que coffrage permanent c"est-a-dire que la poutre n"est pas enlevee apres la prise du beton.
