Title (EN) COUPLING STRUCTURE FOR WATER CHANNELS
(FR) STRUCTURE D"ASSEMBLAGE POUR CANAUX D"AMENEE D"EAU
Abstract: front page image
(EN)A coupling structure for strengthening agricultural or industrial water channels is composed of a number of prefabricated concrete products connected in series against any settlement and upheaval. Connecting plates (1a, 1b) are engaged with recesses (8, 8) formed at adjacent concrete products (5, 5), respectively, and a bolt (9) is screwed through tightening hole (2) into an insert (6). After a bolt (10) is passed through a hole (13) of an eccentric seat plate (11), the bolt is screwed through a tightening hole (3) into an insert (7). When the seat plate (11) is rotated, the adjacent concrete products (5, 5) are urged towards each other. A stopper (4a) is provided in addition to a stopper (4b). Even if compressive force occurs between the concrete products (5 and 5) due to the settlement or upheaval, it is partially born by the bolt (9), the plates (1a, 1b), the seat plate (11), and the bolt (10).
(FR)Une structure d"assemblage pour renforcer les canaux d"amenee d"eau dans l"agriculture et l"industrie comprend une pluralite de pieces en beton prefabriquees reliees en serie et placees contre un tassement de terrain ou en elevation. Des plaques de connexion (1 a, 1b) se logent dans des evidements (8, 8) formes dans les pieces en beton adjacentes (5, 5), respectivement, et un boulon (9) est visse au travers d"un trou de serrage (2) dans une piece rapportee (6). Apres passage d"un boulon (10) a travers un trou (13) d"une plaque d"assise excentrique (11), le boulon est visse au travers d"un trou de serrage (3) d"une piece rapportee (7). Lorsque la plaque d"assise (11) tourne, les pieces en beton adjacentes (5, 5) sont poussees 1, une vers l"autre. Une butee (4a) est prevue en supplement d"une butee (4b). Meme si une force de compression se produit entre les pieces en beton (5, 5) a cause du tassement ou de l"elevation, elle est supportee partiellement par le boulon (9), les plaques (1a, 1b), la plaque d"assise (11), et le boulon (10).
