Definitions

  • the invention relates to a sound screen, comprising a plurality of plate parts of an at least substantially light-transmissive mate­rial arranged in a side-to-side configuration, each plate part being secured to support members.
  • Such a sound screen is particularly employed when abating the sound caused eg. by motorcars or trains, in order to reduce the noise nuisance in residential areas that are eg. located along motorways or railroads, respectively.
  • This known sound screen con­sists of regularly interspaced posts, anchored in a foundation, and flat, transparent plastic plates secured to said posts.
  • the height of the sound screen can be varied, dependent on the adja­cent buildings, and it is also determined by the demands made on the extent of noise reduction.
  • the known sound screen has the disadvantage that on account of the presence of the posts, particularly at an incident angle that is oblique with respect to the screen, the screen is opaque. This is contrary to the effect intended by the transparent plate parts, i.e. the invisibility of the sound screen. This invisibility is of great importance, as tests have shown, as with this type of sound barrier residents prefer a sound screen that hampers their view to the least possible extent, whereas on the other hand motorists also prefer a screen that is transparent to the largest possible extent in order to be able to visually relate to their surround­ings as naturally as possible and thus to be able to get their bearings.
  • each plate part comprises a stiffening of a substantially light-transmissive material, which stiffening extends at least in a direction perpen­dicular to the longitudinal direction of the sound screen.
  • the stiffening is preferably formed by at least one rib that extends in a direction perpendicular to the longitudinal direction of the sound screen.
  • each plate part may have a substantially arched curvature in a direction perpendicular to the longitudinal direction of the sound screen, the rib being located at the round surface of the plate part.
  • this curvature also contributes to removing the optical illusion that the road is narrowed as a result of the presence of the sound screen, which phenomenon is experienced as quite disturbing by motorists.
  • Fig. 1 shows a part of a first embodiment of the sound screen according to the present invention, in which in this example the sound screen has been placed along one side of a road.
  • the sound screen 1 comprises plate parts 2 that have been made of a light-­transmissive material, such as (laminated) glass, a glass-fibre-­reinforced polyester, transparent polyvinylchloride (PVC), acryl­ate, preferably polymethylmethacrylate (PMMA), polycarbonate and the like.
  • PVC polyvinylchloride
  • PMMA polymethylmethacrylate
  • Acrylate has a relatively high impact resistance and is also quite resistant against ultraviolet light and chemicals.
  • the plate parts 2 may comprise a colour shade or they may have been treated at their surface in a manner that influences the transpar­ency and/or in order to avoid possible undesired light reflec­tions.
  • the plate parts 2 are sup­ported by a foundation 10 that may consist of steel, concrete poured on the spot and/or prefab concrete.
  • the arched curvature shown in fig. 1 of the plate parts 2 in a direction perpendicular to the longitudinal direction of the sound screen may e.g. have been obtained by bending an initially flat plate part, e.g. by means of heating, in a mould.
  • the plate parts are extremely form-retaining.
  • the thickness of the plate parts 2 and the extent of the curvature will also be determined by the demands made on the extent of the noise reduction. Occasionally a thickness of 5-12 mm and a screen height of 3 to 6 m is sufficient. With a thickness of 6 mm a sound resistance of as much as 30 dB is obtained.
  • a sound screen 1 may also be impor strictlytant to the form of the curvature whether a sound screen 1 is placed on either side of the road, in view of reverberation of the sound reflected by one sound screen to the opposite sound screen. If the curvature is suitably chosen, standing waves can be avoided and the sound is reflected upwards.
  • fig. 5 shows a number of embodiments of the sound screen according to the invention, each having a differ­ent screen height.
  • the extent of the curvature from the base of the screen is always the same, so that even with screens of which the height varies in the longitudinal direction, a con­tinuous connection of the plate parts is obtained.
  • the sound screen 1 will substantially obtain its sound-abating quality due to a reflection of sound on the plate parts 2.
  • the plate parts 2 comprise a stiffening in the form of ribs 3 that are glued to the round surface of the plate parts 2 by means of a transparent glue or fixed by means of dowel joints (not shown), preferably with dowels of a light-transmissive plastic.
  • the ribs 3 may e.g. have cross-sectional dimensions in the range of 50-100 mm in the one direction, and extend to approximately 300 mm at the most in the other direction.
  • securing means 5 and 6 are present for securing the rib to the pertaining support members.
  • the material of the ribs 3 is at least substantially light-transmissive and preferably the same as that of the plate parts 2.
  • the stiffening may also have the form of edges, e.g. bent thermoplastically, at the upper and/or lower edge of each plate part 2.
  • Fig. 4 shows a bent edge 21 illustrated at the top edge of the plate parts 2 in a second embodiment of the sound screen according to the present invention.
  • Fig. 2 shows a section along the line I-I in fig. 1.
  • the ribs 3 are each mounted on the head edge of a plate part, so that the securing means 5 and 6 of adjacent ribs of adjacent plate parts 2 may be joint, so as to provide a joint securing of the pair adjacent ribs to the pertaining support members.
  • the adjacent ribs may be interconnected by means of dowels 4 of a light-transmissive synthetic material, vide fig. 1.
  • a possible thermal expansion of the plate parts is taken into account and also tolerances of the plate parts and other parts of the sound screen, as well as adjustment tolerances by means of e.g. fixedly glueing a dowel to the one rib and by allowing some clearance in the other ribs with respect to the hole into which the dowel is inserted.
  • the securing means 6 and also the securing means 5 are preferably formed by a hole that is provided in the rib 3, through which a sleeve 7 is inserted, having an outer diameter of e.g. 30 mm, said sleeve 7 comprising threadings at its ends, which threadings co­operate with threaded metal bolts 11. Rings have been received be­tween the bolts 11 and the ribs 3.
  • the pin connection can be devised as light-transmissive to the largest possible extent.
  • the support member 8 is formed by a base 12 comprising an upright steel plate 13 with a hole for allowing the sleeve 7 to pass. In this manner a hinge bearing with the pin connection is obtained.
  • Fig. 3 shows a view from the line II-II in fig. 1.
  • the support member 9 is formed by a base 15 with an extension piece in the form of a rod 16 with a diameter of e.g. 100 mm, a steel plate 17 being secured to the base 15.
  • Said plate 17 comprises a hole for allowing a sleeve 19 to pass, in order to provide a pin connection that is similar to the pin connection of the support member 8.
  • the rod 16 is preferably made of a light-transmissive material, e.g.
  • acrylate and is connected to the base 15 by a swivel connection via a bow 20 comprising two parallel plates with coaxial holes on the one hand, and to a plate cooperating with the securing means 5 on the other hand, so that it is possible to adjust the length of the support member 9 when positioning the sound screen 1.
  • the plate cooperating with the securing means may be formed in accord­ance with the plate 13 of the base 12 or the bow 20 at the other end of the rod 16.
  • a tensioning construction 14 can be provided as indicated in dotted lines in figure 1, so as to further reinforce the support members 8 and 9.
  • Fig. 4 shows an illustration of a support member 22 which com­prises a horizontal, steel perimeter beam 23 on which on either side of a pair of ribs 3, shoes 24 have been mounted that keep the plate parts 2 in their position by means of pins 25, e.g. bolts that are inserted in the holes provided in the ribs.
  • the perimeter beam 23 is mounted on foundation piles 27 that are stuck into the ground and that are horizontally anchored by means of obliquely bored anchores 28.
  • a soil retainer 29 of prefab re­ inforced concrete is arranged between the piles 27.
  • each rib is preferably provided opposite each shoe with one or more steel plates 26 with corresponding pin holes, which plates are each glued to the rib.
  • Fig. 4 shows only one plate 26.
  • the support member 22 can be of relatively limited dimensions.
  • the support members 8 and 9 in the embodiment according to fig. 1 may also be provided with plates 26.
  • Fig. 5B shows a section of the screen according to fig. 4.
  • the shoes 24, the plates 26, the perimeter beam 23 and the piles 27 are preferably made of thermally galvanized steel.
  • the peri­meter beam 23 may e.g. comprise elements of set plate steel with a thickness of 8 mm and a length of 4 m.
  • the perimeter beam 23 may have adjustment means both in horizontal and vertical direction for precise positioning.
  • the support members 22 only take up little surface area, which is important in practice, e.g. if the sound screen is mounted on viaducts in large towns.
  • Fig. 6 shows a further illustration of the mounting of the sound screen on a viaduct.
  • the piles 27 are anchored to the road sur­face.
  • Plate parts 2 of relatively great heights may comprise support members 22 that moreover comprise an extension piece 30 in the form of a steel fork, as is represented in fig. 5C and, in more detail, in fig. 7.
  • the extension piece 30 may be integrated with the pertaining shoes 24.
  • a light-trans­missive, flexible sealing means is accommodated for sealing the slits between the adjacent ribs 3.
  • the seal­ing means is formed by a transparent hose 18 of plastic, said hose 18 extending over the length of the pair of ribs.
  • the sealing means e.g. of extruded, transparent acrylate, may also be a strip that has been inserted in two oppositely disposed grooves in the ribs.
