Definitions

  • the invention relates to a method for increasing the load capacity, Rigidity and vibration damping of a wooden beam ceiling arrangement according to the preamble of claim 1 and a wooden beam ceiling arrangement with increased load capacity, Stiffness and vibration damping according to the preamble of Claim 4.
  • the invention has for its object to provide a method for Increasing load capacity, rigidity and vibration damping a wooden beam ceiling arrangement as well as a wooden beam ceiling arrangement with increased load capacity, rigidity and Specify vibration damping, which refers to measures on the Restrain underside of an existing wooden beamed ceiling and an opening and coring of the compartments unnecessary.
  • This task is in a method according to the preamble of claim 1 by the features of this claim and in a wooden beam ceiling arrangement according to the preamble of the claim 4 solved by the features of that claim.
  • a static reinforcement of load-bearing wooden beams by clamping the wooden beams reached with wooden planks.
  • the wooden planks are aligned in the axial direction of the wooden beams and positioned at a distance to the supporting wooden beams.
  • full-thread screws are used for shear-resistant screwing through the wooden plank at an angle, or vertically to screwed in the top of the wooden beams, alternately in the middle area oblique to a vertical and in the support area both obliquely directed from below to the respective support as also perpendicular.
  • the full thread screws thus form connecting means, the statically considered the tension- and pressure-resistant diagonal bars of a Hidden truss with wooden beams as upper flange and represent wood plank as a lower flange. While in the middle Area only oblique bars are present, must be off Mounting reasons near the support a change of Truss system from only oblique bars to vertical Pressure rods and oblique to the support pointing Switzerlandstäben respectively.
  • the static system represents one by elevation and shear reinforcement prestressed wooden beams used in utility and Break load case a prestressed concrete analogous carrying behavior shows because the pair of forces from the predominantly pressurized upper wooden beams and the tensile lower Wooden plank forms a larger lever arm and thus essential can record higher moments than before.
  • the spacer between beam and screed can be replaced by the existing plaster on substructure or a newly arranged Made of wood wool lightweight panel.
  • Under the wooden planks can a springy suspended underside to be ordered.
  • the wooden planks take over the function of a safe and better oriented substructure for the lower ceiling and at the same time form compartments for damping the cavity between plaster and planking to improve the Sound insulation.
  • the advantage of the method according to the invention and the wooden beam ceiling arrangement is that as a result of stiffening the effectiveness of conventional measures to improve the air and impact sound insulation additionally is increased, or that in an old, may not more so viable wood beam ceiling arrangement in the first place the said conventional measures to improve the Air and impact protection are feasible.
  • the existing wooden beam ceiling made of load-bearing wooden beams 10 with a floor covering 12 on the top, a Gefach whllung 14, and a Sparschalung with plaster base 16 and plaster 18 on the bottom.
  • the existing saving formwork with plaster base 16 and plaster 18 as Spacer for a wooden plank attached to the underside 20, the original with the wooden beams 10 Wooden beam ceiling bolted by screws 22 shear-resistant is.
  • plaster does not exist on plaster base and saving formwork, e.g. on a visible wooden beam ceiling or in the production new wooden beamed ceilings, so is suitable as a spacer a wood wool lightweight panel of thickness 25 to 40 mm in particular, because their perforation to even better Damping the Beamfache leads.
  • the wooden planks 20 form a well-aligned substructure for a spring-suspended ceiling soffit 24 and a sufficient space for the arrangement of sound-absorbing Materials 26.
  • Fig. 2 shows the representation of the mounting operation for undervoltage the wooden beam 10 with wooden planks 20.
  • a pre-drilled Bohle is vertical by means of formwork support 28 and hydraulic pushed up. This transmits the power over the Spacers, e.g. Plaster 18 and saving formwork 16 or one Wood wool lightweight panel, in the wooden beams above 10. The existing deflection of the wooden beam 10 is doing partially or completely reduced.
  • the reaction force is via a load distribution 30 is displaced to a larger area of the floor 32, to reduce deflection of the floor 32.
  • FIG. 3 is an exaggerated representation of the deflection of Wood beam 20 and wooden beams 10, the wooden beams 10 and the wood plank 20 are bent upwards.
  • the wooden beam 10 and the wood plank 20 are bolted shear-resistant, the screws 22 in the middle beam area oblique rods form and to the supports 36, 3B towards vertical pressure bars and oblique to the supports pointing Gystäben switch.
  • the change to vertical pressure bars is for assembly reasons required because of the walls in the area of Supports 36, 38 a diagonal fitting from below, from the support directed away, not realizable.
  • Fig. 4 shows a graphical representation of the deflection over the load of a beam without undervoltage and undervoltage, which was determined in a load test attempt. In both cases results in a linear load deformation behavior without permanent deformation at multiple loads.
  • the measure according to the invention leads in the load deformation test to a doubling of rigidity the single bar. This leads to the conclusion that the carrying capacity the beamed ceiling is significantly improved. Thereby can also be old and maybe not like that anymore load-bearing beam cross-sections, especially for larger spans a very cost effective and economical improvement of the support system can be achieved.
  • Fig. 5 shows the cross section through a wooden beam 10 with a spaced apart and with the wooden beams 10th Schubfest bolted wooden plank 20.
  • the voltage curve is shown in the wooden beam 10 would occur without composite.
  • the right representation shows the voltage curve of the composite system of wooden beams 10 and shear-resistant wooden plank 20.
  • the figure shows that the invention by the load transfer also too a voltage rearrangement leads, despite doubling the external stress spares the old wooden beams 10 and the new Bohle 20 according to their calculable load capacity.
  • Fig. 6 shows a graphic representation of the airborne sound insulation over the frequency. It is recognizable that in the authoritative Frequency range between 100 and 3150 Hz the airborne sound insulation the original ceiling due to the undervoltage clearly is improved.
  • Fig. 7 shows a graphic representation of the impact sound level above the frequency also for a conventional beamed ceiling and an underfloor ceiling with soft flooring. Again, within the relevant frequency range, the Significant improvement in the impact sound protection visible.
