Abstract

A sound damping wall often causes vibration hindrance unless a ditch of sufficient depth is dug at the rear side. This is not longer necessary if a wall according to the invention is used. Said wall consists of multiplex contained in azobé, while the connecting means, with which the panels are attached to posts, have in the case of loading parallel to the surface of the panels, a greater thickness in the direction perpendicular to the panels. The connecting means are preferably metal clamping frames having a bevelled U-shaped cross-section.

Description

  • The invention is related to a sound damping wall comprising panels which are attached by connecting means to posts having a H-shaped cross-section, said connecting means getting a greater thickness in the direction perpendicular to the panels when loaded parallelly to the surface of the panel, and perpendicular to the posts by bolts and nuts.
  • Such a wall is known from CH-A 607 567. The connecting means of that known wall have an irregular S-like cross-section. There is a line- contact between the post and a kink between two straight parts of the cross-section of the connecting means. This feature can easily lead to vibrations. The engagement between the panel and the connecting means is based upon the elasticity of a circle-sector-shaped part of the cross-section of the connecting means. This elasticity will certainly be not very permanent so that it will not take very long until the panels start vibrating under the influence of wind and the traffic racing by. Not only can this lead in itself to noise pollution, but the posts can also start to vibrate as a result. These vibrations can then travel through the ground of the dwellings to be protected unless a ditch of adequate depth can be dug at the rear side of the wall. Of course, there is not always enough room for such a ditch and, furthermore, such a ditch entails extra digging and maintenance costs.
  • The invention now aims at producing a sound damping wall which abolishes the above- mentioned disadvantages and problems. Moreover, the invention aims at producing a wall, which can be manufactured and positioned simply and therefore cheaply, it being taken into account that the reflections of the noise will not reach any unacceptable values if the massive panel has a minimum weight for every surface unit.
  • The invented wall now has as characterizing features that said panels consist of plywood surrounded by a border of tropicai lumber known as azobe, and in that said connecting means consist of U-profiles having legs, a base and bevelled edges connecting the legs to that base.
  • The invention will be elucidated in more detail below with the aid of the drawing in which, by way of example, some details of a sound damping wall according to the invention are shown.
  • In the drawing there is shown:
    • Fig. 1 a horizontal section through a post, a panel and a connecting means, and
    • Fig. 2 a view of the direction of arrow A of Fig. 1.
  • Most of the sound damping walls placed along busy thoroughfares are constructed by placing posts 1, having a H-shaped cross-section at a certain mutual distance, such as 3 m. The parallel legs 2 and 3 of this profile are parallel to the thoroughfare and the centre piece 4 is perpendicular thereto. The distance between the parallel legs 2 and 3 is so great that a panel 5 easily fits inbetween, so that enough room remains for a connecting means 6.
  • Panel 5 consists of a border 7 of azobe, and a multiplex plate 8 of preferably 18 mm thickness, which is contained in grooves of the border. The azobé border parts of preferably the dimension 50x 100 mm are connected to one another in a known manner by wooden pins and preferably the cooperation between the border and the plate is improved even more with the aid of kit 9 in the grooves and/or kit 10 in the connection corners. As shown in Fig. 2 an extra recess can be placed in the border parts 7 for the benefit of kit 10. The panels are manufactured in a number of standard heights and are placed as a unit between the posts 1. To support the panels, corner profiles 11 are welded firmly to the posts on a level with the land.
  • The connecting means 6 consist in Fig. 1 of U-profiles extending over the height of a panel, leg 12 of said U-profiles possibly being somewhat longer than the other leg 13. The base part 14 of the U-profile is connected to the legs by means of bevelled edges 15. If the screw connection consisting of bolt 16 and nut 17 is now tightened, the base part 14 and the bevelled edges 15 will, at a given moment, want to come in each other's path, which will lead to a strong clamping action. If the left-hand space in Fig. 1 between legs 2 and 3 of the H-profile is also occupied by a panel, one should dispose of longer bolts 16.
