Title (EN) SHUTTERING PANEL FOR CONCRETING
(FR) PANNEAU DE COFFRAGE POUR TRAVAUX DE BETONNAGE
Abstract:
(EN) A shuttering panel in the form of a laminated structure consists of two opposing wall-forming sheets (10, 11) and an intermediate cellular-plastic layer (19) connected to the wall sheets. The circumferential edge portions of the shuttering panel are coated with a protective layer (23) of plastic or elastomeric material which covers the edges of the sheets and the cellular-plastic layer. The protective layer (23) not only mechanically protects the edge portions of the shuttering panel, but also seals between abutting shuttering panels when several such panels are assembled into a formwork. The sheets (10, 11) may consist of plywood, and the cellular-plastic layer (19) preferably is made of extruded, expanded polystyere plastic. The protective layer (23) is preferably made of rubber or plastic material. Corner elements (20) are recessed into the corners to protect these and serve as spacers between the opposing wall sheets.
(FR) Le panneau de coffrage décrit, qui se présente sous la forme d'une structure stratifiée, se compose de deux plaques (10, 11) formant les parois opposées et d'une couche de plastique cellulaire intermédiaire (19) reliée aux plaques formant les parois. Les parties de bord circonférentielles du panneau de coffrage sont recouvertes d'une couche protectrice (23) en matériau plastique ou élastomère, qui recouvre les bords des plaques et de la couche de plastique cellulaire. La couche protectrice (23) non seulement protège mécaniquement les parties de bords du panneau de coffrage mais forme également un joint d'étanchéité entre plusieurs panneaux de coffrage en about assemblés de façon à former un coffrage. Les plaques (10, 11) peuvent être constituées de contreplaqué et la couche de plastique cellulaire (19) est de préférence en plastique de polystyrène expansé extrudé. La couche protectrice (23) est de préférence en caoutchouc ou en matériau plastique. Les éléments d'angle (20) sont évidés aux coins de façon à protéger ceux-ci et à servir de pièces d'espacement entre les plaques formant les parois opposées.
