Definitions

  • the present invention relates to a bridge joint, that is to say a joint between two sections of the roadway of a bridge.
  • Bridge joints are required primarily because of thermal expansion and contraction in the roadway of a bridge. Also they accommodate initial contract on setting of concrete in the roadway and relative shear and rise/fall of adjacent roadway sections.
  • the object of the present invention is to provide an improved bridge joint.
  • a bridge joint according to the invention comprises:
  • edge beams having support formations extending therealong, the edge beams being adapted to be fixed to respective opposite ones of the roadway sections and
  • crossbeams spacing features fixed on at least some of the crossbeams and co-operating with the intermediate beams for evenly spacing the latter.
  • the crossbeams will be of uniform length, whereby their angle with respect to the edge beams is determined by the separation of the edge beams and they are maintained parallel.
  • the support formations are open, circular section grooves; and the crossbeams have spherical ends which fit the grooves.
  • the grooves may be supplemented by support lips abutting the underside of the crossbeams, particularly where the edge beams are not expected to rise and fall with respect to each other.
  • the spacing features are cams fixed to the crossbeams and acting on the intermediate beams.
  • the cams may be fixed to the top of the crossbeams; in the preferred embodiment, they are fixed to the bottom of the crossbeams.
  • the intermediate beams have apertures through which the crossbeams extend, with the cams acting on bottom portions of the intermediate beams.
  • Figure 1 is a cross-sectional side view of a bridge joint of the invention.
  • Figure 2 is an underside view of the bridge joint of Figurel .
  • the bridge joint 1 shown in the drawings is set between two adjacent bridge roadway sections 2,3, which are liable to move by a small amount with respect to each other.
  • the joint has steel edge beams 4,5 arranged at the edge of the concrete C of the roadway sections.
  • Each edge beam has a central section 6, which is generally square in cross-section, a horizontal flange 7, which is cast into the concrete and a vertical flange 8, which edges the concrete.
  • the central section has a circular cross- section groove 9, which opens towards the gap G between the roadway sections and the opposite edge beam.
  • Cross beams 10 are regularly spaced along the length of the joint, i.e. across the width of the roadway. They are of square section mild steel tube, with a stainless steel sheath 12 to improve their bearing qualities.
  • a spherical steel ball 14 is fixed, as by welding or pinning. The balls are sized to fit in the groove 9.
  • the angle which the crossbeams make with the edge beams is determined by the fixed length L of the crossbeams between the balls and the variable separation S of the edge beams. Whilst the edge beams remain parallel, the crossbeams will also remain parallel.
  • a number of spacer balls 15 is arranged in each groove 9 between each adjacent pair of crossbeam balls 14.
  • the crossbeams support a number, three as shown, of intermediate roadway beams 20. They are of general I-beam shape, with small grooves 21 in their heads 22. The edge flanges 8 of the edge beams also have such small grooves 21. Via these a diaphragm seal 23 is connected between each adjacent pair of roadway beams. These seals exclude water and dirt from the parts of the joint beneath them.
  • the heads of the roadway beams provide the roadway surface between the concrete of the roadway sections 2,3. Feet 24 of the intermediate beams rest on the crossbeams. These transfer road loads to the edge beams via the balls 14 and lips 16 at the lower side of the mouth of the grooves 9.
  • cams 17 are fixed to the underside of the crossbeams 10. They act against lower extensions 25 of the beams 20, the extensions being fitted to the beams after laying of them on the crossbeams.
  • the joint is thus a coherent structure, which has a variable width.
  • the cams are so shaped as to define a gap therebetween which is the same size as the thickness extensions 25, regardless of the angle ⁇ .
  • the number of intermediate beams can vary. Since the intermediate roadway beams are stiff, the cams need not be provided on each crossbeam. The cams can be provided above the crossbeams, acting against the webs of the intermediate beams, if there is insufficient space for them to act against the beams' feet. For applications where little relative rise/fall is expected, the balls can be replaced by short studs, with flat bottoms bearing against flat bottoms to the grooves in the edge beams.

Abstract

La présente invention concerne un raccord de pont (1) comportant des poutres d'arête en acier (4, 5) disposées au niveau de l'arête du béton (C) des parties de chaussée. Chaque poutre d'arête présente une rainure (9) de section circulaire ouverte du côté d'un espacement (G) entre les deux parties de chaussées et la poutre d'arête opposée. Des poutres transversales (10) se trouvent sur toute la longueur du raccord à intervalles réguliers, par exemple en travers de la largeur de la chaussée. A chaque extrémité des poutres transversales est fixée une bille sphérique en acier (14), par exemple par soudage ou laminage. Les billes ont une taille qui leur permet de s'adapter à la rainure (9). Les poutres transversales supportent un certain nombre de poutres de chaussée intermédiaires (20), généralement en forme de I et dotées de petites rainures (21) dans leur partie supérieure (22). Les bords d'arête (8) des poutres d'arête présentent également de telles petites rainures (21). Cela permet de relier un joint à diaphragme (23) entre chaque paire de poutres de chaussée adjacentes. Les parties inférieures (24) des poutres intermédiaires reposent sur les poutres transversales. Cela permet de transférer les charges qui s'exercent sur la route sur les poutres d'arête par l'intermédiaire des billes (14) et des rebords (16) se trouvant en-dessous de l'ouverture des rainures (9). Afin de maintenir les poutres intermédiaires (20) uniformément espacées, des cames (17) sont fixées en-dessous des poutres transversales (10) et agissent contre des extensions inférieures (25) des poutres (20), lesdites extensions étant adaptées aux poutres après placement de ces dernières sur les poutres transversales.
