Definitions

  • the invention relates to a method for manufacturing a sound-absorbing element by stacking on top of each other a plurality of substantially annular members and at least partially filling the space formed by the thus stacked annular members with a filler.
  • a method for manufacturing a sound-absorbing element by stacking on top of each other a plurality of substantially annular members and at least partially filling the space formed by the thus stacked annular members with a filler.
  • annular members in particular discarded vehicle tyres, are partially cut through, folded open and stacked on top of each other in this state along a reinforcing frame.
  • the tyres which have been cut and folded open and which are therefore substantially W-shaped in top view are then stacked onto each other layer by layer and fixed to the reinforcing frame, and the space formed by the tyres and the reinforcing frame is filled with earth in which shrubbery can be arranged.
  • This method is relatively time-consuming since the tyres must first be cut through and folded open one at a time and subsequently connected to the frame before they can be filled.
  • the thus formed sound-absorbing elements are moreover not very easy to handle.
  • German utility model 7734600 is a sound-absorbing element which is constructed from horizontal rows of annular members, likewise in the form of used vehicle tyres, which are suspended mutually adjacently from horizontal suspension rods which in turn are supported locally by vertical uprights.
  • the tyres are mutually connected herein by connecting strips and enclosed by a jacket.
  • This method is also time-consuming because the tyres must be placed one by one over the horizontal suspension rods which must then be supported such that each tyre can pass the support.
  • the thus formed sound-absorbing element is also not very easy to handle.
  • the invention therefore has for its object to provide an improved method of the above described type.
  • This is achieved according to the invention by a method which has the feature that a curing material is chosen as filler, whereby the annular members are mutually connected.
  • a curing material is chosen as filler whereby the annular members are connected.
  • a sturdy and easily handled sound-absorbing element is obtained in simple manner in one operation.
  • Use can herein be made of a foam as filler.
  • the unfilled spaces inside the stack of annular members generally a stack of tyres, can be filled with a weighting material, for which purpose can be used a waste material reduced in size.
  • An easily handled and robust sound-absorbing element is thus obtained in simple manner and with very low material costs, while the waste problem is moreover alleviated through the use of a large number of waste materials.
  • the invention also relates to a method for manufacturing a noise barrier wherein a plurality of sound-absorbing elements manufactured by applying the above described method are placed mutually adjacently on a ground.
  • a sound-absorbing element 1 is manufactured by stacking on top of each other a plurality of annular members 2, in the shown embodiment discarded vehicle tyres (fig. 1). Use is preferably made therein of tyres having substantially the same diameter.
  • the tyres 2 are stacked between three adjusting members 3 which are displaceable in radial direction by means of displacing jacks 4.
  • Adjusting members 3 each have on their top a clamping element 5 which is displaceable in height direction by means of a jack 6.
  • Tyres 2 are further stacked round an upright reinforcing element 7 formed by a base plate 8, a basket 9 arranged thereon and a central pin 10 which has an end part 11 which protrudes beyond base plate 8.
  • a space 12 which is divided by the basket 9 of reinforcing element 7 into a space 13 located outside the basket and a space 14 bounded by the basket 9.
  • a curable filler 15 is arranged in space 13, which, after curing, forms a strong connection between tyres 2 (fig. 2).
  • Such a filler 15 could for instance be a foam such as PUR foam.
  • the space 14 inside basket 9 can herein be filled with a weighting material 16, for which purpose a waste material reduced in size can for instance be used.
  • a waste material reduced in size can for instance be used.
  • Very suitable for this purpose are for instance the ground remnants of used carpets, but it is also conceivable for this purpose to grind for instance used vehicle tyres of little used sizes which cannot be processed into the stacks. Mixtures of such waste materials can of course also be used. Because the weighting material 16 is poured into basket 9 and is thus bounded, the desired degree of weighting can be obtained by compressing this material in the basket 9.
  • the basket 9 having therein weighting material 16 is further enclosed by the curing foam 15 and thus firmly connected to the outer cylinder formed by tyres 2.
  • the basket 9 will in any case generally first be filled with weighting material 16 before filler 15 is introduced into the remaining space 13.
  • filler 15 can be a foam, but other substances, for instance liquid glues and the like, can also be envisaged. It is also conceivable for the weighting material to be simply mixed with the filler, or even for the whole inner space 12 defined by the tyres 2 to be filled with a curing filler.
  • cover element 17 (fig. 3) in which a plurality of apertures 18 are arranged through which pass threaded ends 19 of a plurality of bars of basket 9. Nuts 20 are tightened onto these threaded ends 19 whereby cover element 17 is fixed to the tyre stack.
  • cover element 17 has in the middle an opening through which a lifting eye 21 functioning as connecting member can be fixed to the central pin 10 of reinforcing element 7. Using this lifting eye 21 the sound-absorbing element 1 is simple to handle.
  • the sound-absorbing element 1 After the sound-absorbing element 1 is finished by arranging cover plate 17, it is provided with a coating layer to allow the sound-absorbing element 1 to better withstand all manner of environmental influences, in particular ultra-violet radiation.
  • the coating layer can further be chosen such that sound-absorbing element 1 is embellished thereby.
  • the sound-absorbing element 1 manufactured in the above described manner can be used as component of a noise barrier 25 (fig. 4).
  • a number of receiving spaces 23 are formed in a ground 22, for instance by pressing or striking foundation tubes into the ground, in which tubes can be received the protruding part 11 of reinforcing element 7 of each of the sound-absorbing elements 1.
  • the sound-absorbing elements 1 can be placed adjacently of each other in simple manner, whereafter they are further connected to each other for reinforcement by for instance a connecting cable 24 trained through the lifting eyes 21.
  • the sound-absorbing elements 1 can otherwise be placed in any desired pattern on the ground 22, wherein all that is important is that an uninterrupted row is formed. A very dense construction is achieved in simple manner with the staggered arrangement as shown in the figure.
  • the cavities between the cylindrical sound-absorbing elements 1 can further be filled with shrubbery by way of embellishment.
  • the noise barrier 25 can of course also be wholly concealed from view by placing shrubbery in front of it or for instance by covering it completely with earth.
  • the advantage of the method according to the invention and the thereby formed sound-absorbing elements 1 lies in the fact that a sturdy, robust and well manageable sound-absorbing element is obtained in relatively simple manner which can moreover be easily combined with other sound-absorbing elements for rapid forming of a noise barrier.
  • the manufacturing cost is relatively low because manufacture is simple and manufacture furthermore starts from basic materials easily obtainable at practically no cost such as discarded vehicle tyres and all kinds of reduced waste material.
  • a contribution is also made in this way toward solving the waste problem, since a large quantity of waste material which cannot be processed in other ways is thus used effectively.
