Definitions

  • the invention relates to reinforced concrete bridges with integrated formwork.
  • Reinforced concrete bridges are conventionally poured onto wooden or metallic or mixed formwork: this amounts to building a pre-bridge, a long and costly operation.
  • the object of the present invention is to propose a solution which allows very inexpensive formwork to be put in place very quickly, without means other than current.
  • the subject of the invention is a reinforced concrete bridge with integrated formwork, characterized in that the formwork consists essentially of parallel steel tubes, extending between the supports of the bridge.
  • - The tubes are juxtaposed and joined together to form the formwork; - the tubes are spaced from each other and, between two neighboring tubes, the formwork is completed by connecting strips; - the tubes are fitted with connectors to improve their connection with the reinforced concrete of the bridge; - the connection strips are made of sheet metal and can be dismantled; - the connection strips are made of sheet metal and integrated into the formwork; - the connection strips are made of wood and supported by supports; - the connection strips are prefabricated reinforced concrete plates and are supported by cleats.
  • the reinforced concrete bridge 1 supports a roadway 2 and a sidewalk 3 provided with a guardrail 4.
  • the formwork used for pouring the concrete of the bridge consists essentially of tubes 5 -9 in steel. These tubes extend over the entire length of the bridge, or at least over each span. They are of a diameter which can go up to approximately 1.5 m without this dimension constituting a limit. These tubes are juxtaposed or arranged with a certain spacing as shown in the drawing.
  • the formwork is completed by connecting strips which connect the pipes two by two.
  • These connecting strips are for example: folded steel sheets fixed to the tubes outside 10 or inside 11 relative to the concrete; pieces of wood 12 supported by supports 13; or prefabricated reinforced concrete plates 14 supported by cleats 15. They are generally placed towards the lower part of the tubes so that the greater part of the circumference of the tubes is in contact with the concrete.
  • the formwork After mounting the formwork and putting in place the metal reinforcements, concrete is poured which fills the space between the tubes and extends above the tubes to form a slab. It is on this slab that the pavement and the sidewalk are arranged.
  • the formwork being made of steel, contributes to the mechanical strength of the bridge and must be taken into account in the calculation of the structure, which results in an economy of iron in the reinforcements of reinforced concrete.
  • the formwork consists of large size tubes of any cross-section and thin. Such tubes are manufactured industrially from strip and are therefore inexpensive, similar to those of laminated sections. They have good inertia in all directions, which makes it easy to handle them in great lengths, given, on the other hand, their relatively small weight for their length.
  • the tubes thus laid, the interval between the tubes at the bottom is closed, regularized and maintained by a formwork in strips fixed to the tubes.
  • This formwork can be made of wood, prefabricated reinforced concrete plates, or steel sheets. In the case of steel formwork, these can either be dismantled later, or secured to the poured concrete by connectors and thus participate in the strength of the structure.
  • the structure according to the invention can be produced very quickly with very common means, at prices much lower than those of conventional solutions, because in fact the formwork is easily and very quickly laid, and does not entail additional cost because it partially replaces reinforced concrete steels.
  • the integration of tubular formwork makes the structure more homogeneous, more resistant. The whole is without problems of calculation and longevity.
