Title (EN) A METHOD OF CASTING CONSECUTIVE CONCRETE ELEMENTS IN A LONG MOULD BED,AND A RAIL-BOUND CARRIAGE FOR MOULD-STRIPPING
(FR) PROCEDE DE COULAGE D"ELEMENTS EN BETON CONSECUTIFS DANS UN LIT ALLONGE A MOULES, ET CHARIOTS MONTES SUR RAIL POUR LE DEMOULAGE
Abstract: front page image
(EN)When casting consecutive concrete elements, e.g. concrete sleepers, there is used an elongate mould bed comprising a plurality of mutually adjacent vertically movable moulds. Mould-stripping, removal of cast concrete elements, cleansing of the mould and the preparation for a further casting operation are effected with the aid of carriages arranged for movement along the mould bed on rails. The carriage for successively stripping the moulds is provided with horizontally extending cylinders (14) arranged to withdraw the mould holders (15) of the mould (16) and spring-loaded down-pressing rods (13) arranged to press the mould downwardly against vertically movable mould holder elements (5) arranged to be swung in beneath the mould. The mould is then cleaned with the use of a separate carriage having a plurality of vertically movable scraper plates (78) arranged to engage the sides of the mould, and a plurality of blow nozzles (67) arranged to deliver a jet of air at high pressure. The separate insert elements which are to be cast in the concrete element may comprise rubber plates (59) or the like carried in cassettes (47) provided with an outfeed mechanism and arranged on the further carriage, which also has separate means (52) for firmly pressing the plates inserted in the mould and sealing the mould.
(FR)Pour couler des elements en beton consecutifs, p.ex. des traverses en beton, on utilise un lit allonge a moules comprenant une pluralite de moules mobiles verticalement et adjacents entre eux. Le demoulage, l"enlevement des elements en beton coule, le nettoyage du moule et la preparation pour une nouvelle operation de coulage sont effectues a l"aide de chariots mobiles sur des rails le long du lit a moules. Le chariot permettant d"effectuer le decoffrage successif des moules est pourvu de cylindres s"etendant horizontalement (14) concus pour retirer les supports de moules (15) du moule (16), et est aussi pourvu de bielles armees par un ressort et appuyant vers le bas (13) concues pour pousser le moule vers le bas contre les elements de support de moules (5) mobiles verticalement, lesquels elements oscillent sous le moule. Le moule est ensuite nettoye en utilisant un chariot different ayant une pluralite de grattoirs mobiles verticalement (78) engageant les cotes du moule, et une pluralite d"ajutages (67) envoyant un jet d"air a haute pression. Les elements d"insertion separes qui doivent etre coules dans l"element en beton peuvent comprendre des plaques en caoutchouc (59) transportees dans des cassettes (47) pourvues d"un mecanisme de sortie et montees sur l"autre chariot, qui possede aussi des moyens separes (52) pour comprimer fermement les plaques introduites dans le moule et fermer le moule hermetiquement.
