Definitions

  • the present invention relates to a method for manufacturing any composite structural building element of wood or its derivatives and concrete such as floors and beams also provided with overhanging parts, pillars and partitions, etc., both manufactured in factory or on building yard, both delivered at or directly installed on site, and suitable both for new constructions or the static retrofitting of the already existing constructions, also in earthquake zones, as well as constructions able to withstand a considerable fire load, moreover also the static retrofitting and the functional recovery generally of buildings and particularly of sport facilities, a lot of buildings even of recent construction needing the improvement of their basic structure and the refurbishment of their side structures ⁇ and roof coverings .
  • a peculiar feature of the finding is to accomplish the integral connection between wood and concrete by the preliminary application to wood of an adhesive having a high resistance and molecular stability in time such as a two-component epoxy adhesive (or resin) . Furthermore, the ' following green-mixed, fibre- reinforced filling concrete casting is bound to the adhesive before the latter begins to cure.
  • connecting elements of metal or other materials between wood and concrete are not indispensable .
  • wood-concrete methods of construction will still be more basic in the near future for many reasons, including: wood is a material that can be renewed, has a reduced volume mass and can be easily worked; - the today methods, as it is the case of the laminated materials, allow large-size elements without any great defect to be provided;
  • - concrete is a good protection of wood if suitably waterproofed, especially in case of constructions exposed to weather such as footbridges and wharves;
  • - wood-concrete combinations allow considerable structural simplifications because of the natural self-carrying tendency of wood which can perform initially the function of supporting the concrete casting with which it will form one body after the maturation of the mixture;
  • the new method is more advantageous than other construction methods even because the energy cost due to weight, working and installation is reduced;
  • the present finding is a new, original solution over any known technique and any so far applied method as well, and is valid for the construction both of horizontal and vertical structures of any size without the need to use connecting elements of metal or other materials either to be embedded both into wood and concrete or fastened to one of them and embedded into the other one.
  • the wood-concrete integration and the hindrance to their mutual sliding are achieved by the application of a viscous adhesive to wood, thus providing a waterproof effect to the latter.
  • the adhesive is integral both with wood and concrete which is cast (poured and spread) under green-mix condition as the curing of the resin is still in the initial step, i.e. before the state of gel is reached. Accordingly, the gluing of concrete begins under its green-mix condition and sets upon maturation (setting) and remains as such all over the life time of the construction.
  • the method according to the invention allows not only to do without the known connectors but also the coating technique that uses bands, fibre tissues, and sheets of pre-impregnated fibres or steel.
  • the finding is able to match the resistance properties of structural elements in earthquake zones, as well as constructions that should withstand a considerable fire load. In those cases, the finding has a great importance not only in the new constructions but also in the recovery of the existing building estate.

  • an adhesive or resin 2 preferably a two-component, epoxy resin, is directly applied to the surface of wood 1, and the concrete casting 3 is poured during the "open time" of adhesive 2, i.e. the time in which the resin keeps its property of adhesion to materials.
  • Said adhesive 2 should have a limit workability duration (also called “pot life” or “open time”, i.e. period of time from the preparation during which an adhesive is usable for the following operations before setting or reticulation which modifies essentially the viscosity, adhesion capability, etc.) which is compatible with the middle-long operation time to carry out the concrete casting 3 during the pre- manufacturing or on yard.
  • a limit workability duration also called “pot life” or "open time”
  • adhesive 2 can cover as a whole one or more surfaces of wood 1 or be spread in parallel strips, orthogonal or oblique cross strips, or in lengths.
  • the surface of wood 1 on which adhesive 2 is spread must be clean and preferably dry (reduced humidity content) but not wet, otherwise a water film between wood and adhesive would be formed.
  • Adhesive 2 can also be enriched by metal fibres, synthetic fibres or any other kind of fibres and something else which is compatible and suitable to be embedded to improve the static performance and the safety over long time.
  • Concrete casting 3 having the designed resistance for example due to the reinforcement with steel, carbon, glass, synthetic, hybrid fibres, etc. is applied directly to wood surface 1 treated by adhesive 2 which is still in the state of "open time", i.e. in the time interval during which the curing is at its initial state and far from reaching the state of gel, in order to prevent cracking, to accomplish a considerable tensile strength, to increase the shearing stress strength,, and to improve ductility and toughness as well .
  • Lightened concrete 3 can also be used and there is no contraindication to the use of known measures such as fluidising additives, superfluidising agents, retardant agents, accelerators, aeration agents, antifreeze, expanders, water-repellants, etc., provided that they are compatible with adhesive 2 used.
  • lightening elements of polystyrene 5 or the like or hollow elements of fired bricks or wood-cement can certainly be inserted into the composite system.
  • the resistance of the inner ribs of concrete which are formed between lightening elements 5 should always be tested.
  • tubular, spherical or differently shaped elements can also be inserted into composite wood-concrete elements 1, 3 if this is compatible with the structure or necessary for any reason.
  • channels 6 for the passage of pipes, etc. can also be arranged in the thickness of concrete 3.
  • the method is also suitable for the reinforcement of the already existing floor and beams subject to thorough cleaning of the surfaces on which the adhesive will be applied and after having supported the wooden elements from the bottom or linked the same by provisional tie rods which are fastened to the high portion of the side walls or other overlying structural elements and held in their positions until concrete sets and achieves its carrying capability in combination with wood.
  • the method is also applicable to the recovery of old wooden structures of coverings such as trusses ands beams.
  • plate systems cab be provided by applying adhesive 2 and the following concrete casting 3 and, if necessary, by using also lightening elements.
  • the horizontal thrusts can also be born by the already existing wooden chains reinforced inside by glued steel bars (for example FeB44k for reinforced concrete or Dywidag steel bars 900(1000) .
  • the solution may also involve the additional use of connectors (e.g. stakes) to be inserted into the rafters of trusses and beams.
  • electrically welded meshes 8 having an anti-shrinkage function can also be inserted into concrete casting 3 or steel bars for reinforced concrete can be used at the bearings of combined wood-concrete beams when the static continuity is a necessity (figs. 16 and 17).
  • the disclosed method provides additional connectors in those cases where the static loads are greater and the static bearing capability must guarantee the maximum safety, for example, where conventional connectors, brackets, plates and anything else including coating techniques with fibre fabrics are used, and where the structural elements manufactured by the disclosed method have been too thinned during the construction work as it is the case of the unexpected passage of pipes 6 or the application of excessive loads.
  • both composite structural elements which are prefabricated in factory or on yard and composite structural elements directly manufactured upon installation can be provided according to the invention by the same advantages and procedures.
  • suitable casting containment side walls are used (fig. ⁇ ) .
  • An adhesive 2 for example a two-component epoxy resin, with a pot life compatible with the prefabrication time in factory or the construction time on yard is spread in strips or lengths on the whole surface or a portion thereof of the previously cleaned wooden structure 1.
  • the composite structural element is integrated by the concrete casting 3 having the resistance defined by the design calculation and carried out according to the invention within the "pot life" of adhesive 2.
  • concrete 3 can be reinforced with metal or synthetic fibres 4 and the mixture can be corrected by the addition of additives.
  • the composite element can be lightened by the insertion of synthetic material 5 and/or provided with channels 6 or other (figs. 14 and 15) .
  • surface cuts 9 can be made in a direction which is essentially transversal to the wood fibres 1 in order to receive steel rods 10 preferably having improved adherence or any other known materials (for example glass pr carbon fibre rods or wood lists or its derivatives) which are able to be glued upon manufacturing prefabricated wooden panels or during the application of- adhesive 2 in order to avoid or considerably reduce the capability of wood 1 of being deformed (swelling or shrinkage) in the transversal direction caused, for example, by the inside humidity variations (fig.. 10 and 11) .
