Definitions

  • the present invention which of model tests and studies were carried out at ENPEPE-FORMEQUIP Geomaterials Laboratory, concerns the realization of mixed wood-concrete structures, especially for obtaining aprons of engineering structures such as bridges.
  • Such structures include solid wood or laminated beams glued to their part lower and a concrete compression slab connected on the beams at their upper part.
  • the object of the present invention is to remedy to this disadvantage and it proposes for this purpose substitute, for metal beams, modes of known construction mentioned above, beams of wood of section defined according to the loads applied (may vary from solid wooden section solid in an I-section also in solid wood or a section of complex shape in glued laminate). She has also for object, thanks to a judicious choice of position of the neutral fiber of the composite section (at the border between wood and concrete), to decrease considerably the quantities of steel to be put in place to arm the compression slab.
  • connection systems which have only used for building floors and low capacity gateways, are not designed to withstand all compression and shear generated in engineering structures.
  • the connector which can be consisting of a folded sheet or obtained by welding two standard angles in head-to-tail position, has an opening on its upper vertical wing for the passage of a longitudinal streak intended to be drowned in concrete.
  • the connector according to the invention is perfectly suited to the execution of decks with a mixed wood-concrete structure. Indeed its upper part works exactly as in mixed metal / concrete decks in which the connector is embedded in the compressed part of the transmitting concrete a compression which dimensions it (it also prevents, thanks to the thread passing through all connectors in a row, lifting the slab). Of even its lower part pressed into a slot in the beam transmits in the best possible conditions wood compression within the limits of constraints admissible of it (defined by calculation). The mobilization of efforts is ensured by filling of the slit using the product defined above.
  • the connector is temporarily fixed on the wood by a point and the efforts of tearing off connector-wood are taken up by constituted bolts a rod inserted in a pilot hole and sealed with product defined above in order to reconstitute the material around the stem, and a head opposing the uprising.
  • the set of connectors thus defined according to the invention is able to resist all efforts generated by the cutting forces known in the engineering structures including fatigue efforts.
  • the longitudinal wooden beams are normally braced at a rate defined by the calculation. These spacers are in principle made up a steel tube taking up the shears crossing a wooden concrete element which takes up the compressions and a FE 500 steel clamping rod or hard steel - (depending on the efforts concerned) - which resumes pull-ups.
  • the wooden beams rest on headers constituting supports.
  • prefabricated elements placed on the bank of the deck on a side notch of the edge beams both serve as vertical lost formwork for the compression slab and the overlying sidewalk but also of protection against the flow of water the along the edge beams and decorative facing.
  • the invention as defined can be implemented implemented both in developing countries development for its maximum use of local resources and the simplicity of its execution, and in industrial countries that wish to develop the wood industry at reasonable costs thanks to low consumption of labor on site properly said.
  • FIG. 1 there is shown a bridge deck produced according to the invention, which comprises wooden beams 1 which can be solid or laminated glued.
  • the beams are section in I and consist of several elements superimposed assembled together. They could however be rectangular.
  • Beams 1 extend in the direction longitudinal of the bridge between piers and abutments, and they are braced using a set made of 2 steel tubes passing through butons wood 3, the whole being tightened by pre-stressed rods 4.
  • the beams 1 are notched by notches 5, intended to receive prefabricated concrete vaults 6 which are arranged in arch shape and serve to form the space included between the beams 1.
  • the outer notches 5 of the edge beams allow to support cornices prefabricated 7 which have as their object, in addition to their role decorative and protective beams, formwork vertically the concrete slab 8 of the deck as well as the overlying sidewalk 9.
  • Beams 1 and prefabricated concrete blocks 6 serve as formwork for pouring the concrete slab 8, which is simply armed with a double layer of trellis welded to resist some conditions to limits, and not at the transverse moments which are eliminated thanks to the arch effect created by the concrete blocks 6.
  • Connectors 12 in the form of a double angle connect the wooden beams 1 to the concrete slab 8 in opposing the sliding forces between these elements.
  • a sealing layer 10 and a wearing layer 11 cover the concrete slab 8.
  • the connector 12 consists of a sheet folded about 8mm thick S-shaped without upper and lower bars produced by folding or by welding two angles together.
  • the amount upper 13 has dimensions of the order of 10cm x 10 cm. It is drilled with a hole 14 allowing the introduction of a round strip of about 12mm.
  • a central hole 19 allows the introduction of a connector positioning and fixing tip.
  • the lower upright 20 has dimensions of the order of 10cm x 3.5cm.
  • the vault in prefabricated concrete blocks are made using two shore lines 22 and a key line 23 extending slightly beyond the beam in order to form the ends 24 of the apron projecting from the beams wood.
