Description

Kit for the production of plantable noise barriers from prefabricated components

The invention relates to a kit for producing plantable Noise barriers made from prefabricated components according to the preamble of claim 1.

Known noise barriers that can be planted are used as transverse wall elements Frame-like support body is provided from support beams inclined towards each other in a roof-shaped manner, each transverse wall element with at least two from bottom to top stepped against each other offset supports for the longitudinal wall parts is formed.

In connection with each support beam, a vertically downwardly directed support foot is provided, which is in a foundation block can be used with a matching recess.

Such noise barriers have one of the span of the roof-shaped mutually inclined support beams correspond to the space required, but sometimes in very cramped conditions is not available / so that noise protection fences are used must be / which, however, often do not have the necessary sound absorption capacity and hardly adapt to the surroundings * In particular, a planting of such noise protection fences in the manner / as is the case with the known Schal.1 protection walls possible is / not given.

The invention is based on the object of providing a kit for the production of noise barriers that can be planted in particular to create from prefabricated concrete or artificial stone parts / with the such noise barriers even under very cramped conditions Conditions can be erected in a space- and material-saving, statically flawless construction.

This object is essentially achieved according to the invention by the characterizing part of claim 1.

Due to the inventive design of the transverse wall parts with a vertically towering / pole-shaped support body, the a support cross-section that is essentially the same from the support foot to the supports for the two upper stone longitudinal wall parts has and on which the side supports for the longitudinal wall parts with one of the support foot or the one below Support outgoing, on opposite sides of the support body each V-shaped outwardly directed support legs start, there are particularly favorable structural conditions in spite of the narrow, space-saving construction such plantable noise barriers with every occurring height to produce absolutely stable and permanent. In particular the longitudinal wall parts find a secure hold on the V-shaped outwardly directed support legs of the supports with optimal strength of the bulkhead parts despite the material-saving construction achieved.

Both in terms of statics and in terms of material consumption for the production of the transverse wall parts it is particularly advantageous according to a further feature of the invention, if the support quays on the transverse wall parts transverse to the

preferred embodiments of the invention are in Drawing shown schematically. Show it

Pig. 1 shows a structure of a noise protection wall from prefabricated concrete parts in a first production phase in FIG perspective view,

Pig. 2 a side view of an assembled noise barrier before filling with soil,

Pig. 3 shows a vertical section through the noise protection wall according to FIG Section line III - III of Fig. 2,

Pig. 4 the support foot of such a noise protection wall in an embodiment modified from FIG. 3 and

Pig. 5 shows a partially sectioned illustration of an upper section of the noise protection wall after it has been filled with Soil and after planting.

The noise barrier shown in the drawing consists of a prefabricated one Concrete or artificial stone parts and consists of vertical transverse wall parts 1 and these on opposite sides connecting longitudinal wall parts 2 together. The bulkhead parts 1 Bind with the support feet pointing downwards, inserted in matching foundation blocks 3.

The longitudinal wall parts 2 are on the transverse wall parts 1 in to the outside inclined lateral supports 4 arranged in steps one above the other and delimit a space for the recording between them of soil, which is then planted.

As shown in particular in Fig. 1 and 3 of the drawing / the transverse wall parts 1 are formed with a vertically protruding, substantially pole-shaped support body, the one from the support foot 5 to the supports 4a for the two uppermost longitudinal wall parts 2 atwa has a constant support cross-section and on which the lateral supports 4, 4a for the longitudinal wall parts 2 with one of the support foot 5 or the one below located support 4 outgoing support legs 6 attach on opposite sides of the central support body is directed outwards in a V-shape.

The individual support legs 6 on the transverse wall parts 1 are transverse to the bearing plane 7 of the longitudinal wall parts 2 from the supports 4, 4a tapered wedge-shaped towards the top and delimited each a wedge-shaped widened upward receiving slot 8 for the Longitudinal wall parts 2. The cut out at their two lower ends and on the transverse wall parts 1 at different heights Longitudinal wall parts 2 arranged vertically one above the other are each slightly inclined towards the outside relative to the vertical and thus emit the incident sound waves essentially downwards. The space between the arranged on both sides Longitudinal wall parts 2 is filled with soil.

At the upper end of each transverse wall part 1 there is one of the two uppermost lateral support 4a protruding, wedge-shaped tapered central support 4b with a vertical receiving slot 4c for the arrangement of vertical longitudinal wall parts 2 in the longitudinal symmetry plane of the noise protection wall.

While 3 of the support leg 5 of the Querwnndelementes 1 shown there interspersed in Fig. The associated foundation block 3 in full length with a constant rectangular cross-section, the support leg 5 is in the example shown in Fig. 4 exemplary embodiments game shorter auegebildet, and the foundation block 3 has an only upwardly open recess 9 for the support foot 5,

However, following the two vertical support leg limits upwards in accordance with the two bottom supports that are connected to it, V-shaped outwards legs 6 of each transverse wall part 1 is widened and forms lateral contact surfaces 9 a for the inclined support legs 6.
