Definitions

  • plastics are sensitive to low temperatures and UV radiation and therefore require permanent control, monitoring, maintenance and periodic exchange.
  • the invention aims to solve these problems and one To create device of the type mentioned, the over long periods and in all possible climates is weatherproof and maintenance-free.
  • EPS is according to DIN 7728 T1 (April 1978) Short name for expandable polystyrene.
  • Polystyrene again, according to DIN 7728 T1 (April 1978) is the most common Term for poly (l-phenylethylene).
  • Expanded particles are now referred to as EPS concrete Polystyrene, which are bound in cement paste and optionally Additives such as fine sand, grit, gravel, expanded clay, pumice, Perlite or the like contain. Such a manufacturing process is described in AT 391 862 B.
  • polystyrene recycled EPS packaging materials that result in grain sizes up to 12 mm and larger, sometimes up to about 30 mm, be crushed and used as the main aggregate for the Concrete mixture used according to the invention can be used can.
  • EPS particles before merging with subject the cement paste to a heat treatment on the surface be causing the surfaces of the particles "glaze” and thus from a water impermeable Are surrounded.
  • EPS particles are used to produce the Noise protection device used EPS concrete in particular resistant to weathering. This heat treatment is closer in AT 394 548 and AT 401 774 B. described.
  • a noise barrier made of EPS concrete according to the invention is done either by making, i.e. casting between formwork elements, on the spot, or by Erecting the wall from prefabricated blocks, which is preferred becomes.
  • the latter variant can either do so be carried out from preferably horizontally placed Blocks the wall is erected, or that vertically erected blocks between stands or on one Heavy concrete wall to be attached.
  • blocks with a thickness of 5 to 10 cm, possibly also 15 or 20 cm thick and an area of 0.25 m 2 to 1 m 2 are preferably laid as brickwork as a brickwork .
  • the selected proportions depend on the available space and the transport and lifting devices available at the construction site and can vary within wide limits due to the low density of the material according to the invention combined with its great strength. Accessibility for machines and equipment along the road is usually good, so that large-format elements can be used.
  • the blocks can in this case have vertical recesses with which they on the Posts can be anchored, for example, that the posts come to rest in these recesses and the remaining space with fast curing Concrete or the like is backfilled.
  • these blocks can be installed both in the Condition horizontal as well as vertical direction through holes extending from end wall to end wall have several horizontally side by side Blocks or several vertically arranged one above the other Blocks joined together by inserted reinforcement elements also through concrete or the like. especially assembly foam firmly connected to the blocks to each other anchor and so the stability of the erected wall increase. It is of course possible to do such Reinforcement elements on the rear facing away from the sound source to provide the block in the form of grooves or depressions, whereby the introduction of the elongated Reinforcing elements is facilitated for backfilling the grooves but formwork is necessary.
  • An essential embodiment of the invention relates to Design of at least the surface facing the noise source of the pre-made elements.
  • This surface points According to an embodiment of the invention holes on the preferably go 6 to 10 cm deep in the wall element and end blind there. These holes are preferably different deep, with a certain number of holes, preferred not more than 25% deeper or less deep than this preferred depth range can be.
  • the cross-sectional areas of the holes are preferably over 25%, particularly preferably over 33% and very particularly preferably about 40% of the surfaces they cover.
  • the hole diameters are when circular holes are made preferably between about 4 and about 8 mm, but can holes up to 12 and 15 mm can also be provided.
  • the material used according to the invention allows this Holes not only by drilling, but also by indentation of nail-like thorns without it to a significant extent to damage material webs comes between the indented holes. It can push in a variety of holes at once so-called nail boards are used. In the preparation of of the holes in this way has proven to be beneficial proved the nails with water before each pressing, which may reduce the surface tension Detergents, for example a dishwashing detergent, was added to wet.
  • the particular advantage of using the holes such nail boards is not only the inexpensive one Creation compared to drilled holes, but also the fact that it is possible to do other than circular To generate cross sections, which has the particular advantage that a larger side wall is formed per hole, than with circular holes with a comparable cross-sectional area, causing the sound absorption that yes the surface by converting the sound energy into friction and thus takes place in heat, is improved.
  • the holes are formed by pressing in nails or thorns, but these are not made using a nail board normally driven to the surface to be treated, but are, preferably in a variety, on a pivotable Shaft arranged and have a circular arc shape with the Center of the circle on the axis of rotation of the shaft to bent when penetrating into the surface of the wall element Creating channels.
  • the holes run the surface with increasing depth of penetration and thus reliably prevent the ingress of water and thus the disadvantages of corrosion or degradation or of freezing.
  • This advantage can also be achieved by pushing it in at an angle straight, but arranged diagonally on a nail board Nails are achieved.
  • Another embodiment relates to the application of a thin, weatherproof paint through which the rough surface texture is retained, the Walls of the webs or the hole walls at least in the Area of the mouths of the holes to the surface water and be impregnated to repel dirt.
  • Fig. 1 is a section of a constructed according to the invention Noise barrier shown, made up of individual Blocks 1 of different height h is built.
  • the wall is only shown in its lower area.
  • the blocks have the same length a and width b and are tower-like in the illustrated embodiment, built without the usual longitudinal composite of masonry, but what because of the usually low height for touch-up cases in the event of damage caused by motor vehicles and the like is cheap.
  • each of the blocks 1 according to the invention shown is by dotting the creation of the invention preferred surface structure by attaching Holes indicated. It can, to make laying easier, each of the blocks 1 has such holes on all sides have, in order not to the orientation of the Block, but it is also, especially in the In case of non-square blocks, possible only one or to design two opposite sides according to the invention.
  • Fig. 2 is a horizontal section through a vertical mountable block 1 shown. She points to the Side grooves 2 facing away from the two grooves 4. In at least one of these grooves 4 comes anchored in the ground vertical post 5 to lie. After adjusting the Blocks this post 5 with block 1 through Pouring with concrete, by foaming with assembly foam or connected by attaching clamping means and so the block 1 fixed.
  • connection opening 6 shown in the Connection of the assembled blocks with the analog connection openings Align 6 of the neighboring blocks is coming.
  • connection openings 6 can be horizontal horizontal reinforcements, as is common in the construction industry are introduced and through concrete or assembly foam or the like. be fixed. In this way it becomes mechanical Stability of the noise barrier increased significantly when such reinforcements are introduced in the area below about a meter above the ground will be an improvement of impact protection in the event of a motor vehicle collision due to the tensile effect of the inserted reinforcement reached.
  • Fig. 3 is a surface of a block 1, the with rectangular holes according to the invention is provided, shown. These holes can be designed accordingly Thorns are created and preferred to exhibit Dimensions between 3 x 3 mm to about 20 x 10 mm, in Extreme cases up to 20 x 20 mm. As from Fig. 4 can be seen, there are similar dimensions for round holes between about 6 mm in diameter and 20 mm in diameter.
  • FIG. 5 shows in a schematic section like a curved nail 7 by twisting about an axis 8 bent holes 9 in a block 1 creates. It is in this Case, as already briefly indicated above, advantageous, mark the block so that it is clear in the case of assembly is determined in which direction the holes 9 are from the vertical to the surface to get a correct one Ensure assembly without the fitters each one Have to examine the block in detail.
  • the invention is not limited to the described embodiments limited, but can be modified in various ways will. So can increase mechanical stability the contiguous sides of the blocks be designed in the manner of tongue and groove, it can Fasteners and assembly elements in prefabricated Blocks can be cast in and it can be used for Cover the side ends and lie on the floor special precautions will be provided for upcoming blocks, around these special elements both mechanically and optically to adapt to their function.
