Definitions

  • the invention relates to a method for manufacturing a steel-reinforced plastic composite beam or pillar.
  • beams and pillars to be manufactured of plastic composites are known, in which beams or pillars e.g. glass fiber or carbon fiber is used as a reinforcement.
  • beams or pillars e.g. glass fiber or carbon fiber
  • beams or pillars comprising reinforced plastic bodies having steel reinforcements are known and their preparation disclosed in DE-A-1956826.
  • a method for manufacturing a steel-reinforced plastic composite beam or pillar characterized in that the plastic composite beam or pillar (20) is manufactured by placing steel reinforcements (30, 40) in the beam or pillar (20) by utilizing the pultrusion technique at the same time as the beam or pillar (20) is formed by pultrusion.
  • the pultrusion technique is, for example, described in US-A-4301201 and US-A-4394338.
  • the cross-sectional area of the beam produced according to the invention can in certain applications be dimensioned smaller than that of a conventional beam, whereby material is saved and also material costs are reduced, since the rigidity of the beam increases owing to the additional requirements.
  • the inner section of the beam or pillar can be filled with a poly-urethane, a cellular polystyrene or concrete filling for preventing the buckling of the plane-like surfaces of the cross-section during bending stresses.
  • the invention also provides more applications for plastic composite beams or pillars due to their additional rigidity, and the steel parts make the fixing of profiles with screw joints possible.
  • the solution according to the invention can also replace e.g. corresponding reinforced-concrete, wood or aluminium structures.
  • Fig. 1 In Fig. 1 is shown a straight beam or pillar 20, whose ends are supported via supports 12. The additional reinforcements are marked with dotted lines indicated by a reference number 30.
  • a plastic composite beam or pillar 20 comprises a reinforced-plastic body and as an inner material 32 polyurethane or cellular polystyrene.
  • the plastic composite beam or pillar 20 according to the embodiment shown in Fig. 2 is manufactured by utilizing the pultrusion technique in such a way that the steel reinforcements 30 are added to the plastic composite beam or pillar 20 in connection with the pultrusion.
  • Fig. 3 shows a plastic composite beam or pillar 20, in which the steel reinforcements are in the form of steel plates 40.
  • the remaining structure of the plastic composite beam or pillar 20 corresponds to that shown in the other figures in such a way that the reinforced-plastic body is indicated by the reference number 31 and the inner section of the beam, made of polyurethane or cellular polystyrene, is indicated by the reference number 32.
