Definitions
- cassette-like wall parts made of aluminum are joined together in a caste shape to form a wall. These are mounted on spaced posts, the wall elements being inserted in the grooves of H-shaped steel profiles.
- Such made of aluminum wall elements are usually very expensive to achieve a sufficient soundproofing effect.
- precautions must be taken to protect the walls from the erosive effects of the environment.
- the wall elements of a noise barrier made of a combination of compacted mineral aggregates or aggregates of glass and organic adhesive high sound insulation is achieved due to the high porosity of the wall elements and the high density of the building material. Since sound insulation values generally depend on the density of an insulating material, the high specific weight of mineral aggregates or of glass has a fundamentally high effect. Another- On the other hand, the aggregates are also significantly cheaper than metals or processed wood. This is the case in particular when using quartzite, granite, basalt and quartz as aggregates.
- the grain size of the aggregates has a significant influence on the insulating effect, on the one hand the density of the building material, as mentioned above, should be high and on the other hand, the porosity has a dampening effect on the sound. Preference is given to aggregates whose average size of the grain is between 1 and 7 mm. With regard to the influence of the porosity, particularly favorable values result with a void fraction of up to 45%.
- Proven average grain sizes d k of the aggregates are in a range between up to 3 mm, 2 to 3 mm, 2 to 4 mm, 2 to 5 mm or 3 to 7 mm.
- the particle size distribution is defined according to DIN 66145.
- the parameter n is at least 9 and is determined neglecting 1% oversize and undersize each.
- the adhesive is preferably a two-component polyurethane adhesive. Also useful is a hot melt adhesive, a two component epoxy resin or a one component polyurethane adhesive. Suitable adhesives are offered, for example, by TerraElast AG.
- a major advantage of using two-component epoxy resin adhesive is seen in its environmental impact.
- the building material of the wall elements for example, has no toxic effect on molds and is considered microbially difficult to degrade. Nevertheless, substances elutable from the wall element can be well degraded, as material trials have shown. As washing tests prove, there is no chemical interaction between surface water and the building material, so that rainwater that seeps through the wall elements can be discharged untreated into the sewer or can safely drain into the groundwater. Finally, you can
- Wall elements are disposed of after their use phase in a soil or gravel washing system without negative environmental effects. Alternatively, after comminution, reuse as granules is also possible.
- a structure of the noise protection wall by the wall elements between spaced posts are mounted, while several wall elements can be arranged one above the other.
- An adhesion of the wall elements together avoids gaps through which the sound insulation could be disturbed.
- a particularly effective improvement of the sound damping results from a construction of the noise protection wall after which the noise protection wall is designed to form gaps between two walls, wherein at least one wall is designed with the wall elements.
- the noise protection wall is designed to form gaps between two walls, wherein at least one wall is designed with the wall elements.
- the spaces are filled with sound-insulating filling material such as blast furnace slag or tire granules. Erflndungsloom the task is achieved with respect to the method for producing a noise barrier by the features of claim 15. Accordingly, the production takes place according to the following process steps:
- the mixing takes place in a location remote from the construction site and that subsequently the mixture is stored in a container, e.g. Container or transported by a silo vehicle to the site and processed there.
- a container e.g. Container or transported by a silo vehicle to the site and processed there.
- FIG. 1 a schematic representation of a noise protection wall mounted along a road
- FIG. 2 a horizontal section through a noise protection wall in a two-shell construction
- Fig. 3 is a horizontal section through a noise barrier with several juxtaposed wall elements and Fig. 4 is a horizontal section through a noise barrier in single-shell design.
- FIG. 1 clearly shows the arrangement of a noise protection wall 1 along a road and the necessary elevation, which results on the basis of the guidelines for road noise protection (RLS).
- the noise barrier is connected to the ground via a foundation.
- a noise protection wall 1 is shown in bivalve design. Between two spaced posts 2 from a U-shaped steel girder, one wall element 3 forms the front and the rear wall of the noise protection wall 1. The posts 2 are each anchored in the ground via a foundation (not further shown). The two wall elements 3 are spaced apart in parallel and thereby form a gap 4, which is filled with a sound-absorbing, free-flowing material.
- the wall elements 3 are each mounted on the inside of the web 5 of the post 2. In the formed by the post 2, directed to the wall elements 3 groove 6, the wall elements 3 are held, which thus withstand the pressure of the filling. In the groove 6 more, each 6 cm thick wall elements 3 are inserted one above the other and glued together at the end faces.
- a plurality of cassette-shaped noise protection elements 7 are arranged side by side to form an elongated noise protection wall 1.
- the noise protection elements 7 are designed in two shells with wall elements 3 arranged one above the other.
- a respective termination post 2 ' is positioned, which holds the wall elements 3.
- one center post 2 is provided, which is formed by an H-shaped steel beam.
- the building material of Wandeiemente 3 is a combination of aggregates with a hot melt adhesive.
- Suitable additives are a selection of quartzite, granite, basalt and quartz; in the described embodiment, colored granite is used.
- the average size of the granite grain is in the range between 2 and 5mm.
- the particle size distribution is defined according to DIN 66145, with a parameter of at least 9 and neglecting 1% oversize and undersize.
- a noise protection wall 1 in inexpensive einschaliger construction shows the embodiment of FIG. 4. Between two spaced posts 2 from a U-shaped steel beams are several wall elements 3 in a thickness of about 10 cm are arranged one above the other.
- the wall elements 3 are each mounted in the groove 6 of the post 2 between the two webs 5 of the post 2.
- the noise barrier consists of a U-profile beam of different widths and heights.
- the filling consists of prefabricated TerraElast sheets with grain sizes 1-3 to 11/16 mm, depending on the required sound absorption values, these are min. 2 cm max. 10 cm attached to the carrier profiles inside left and right.
- the size of the elements can be produced in various sizes depending on the requirements profile and taking into account the wind pressure with or without reinforcement.
- the resulting cavity between the elements can be filled with different materials on site, depending on the desired sound absorption values.
- shredded old rubber tires or blast furnace slag are glued or filled unglued.
- noise protection wall not only the excellent sound absorption values, but also the speed of the construction of the wall, as well as the endless color design of the walls are to be emphasized.
- the production costs of the noise protection wall are around half as conventional concrete walls.
