- the jacket is applied with sufficient force against the flanks of the rail to hold the rail in position when a vehicle passes on this rail.
- this force is achieved by fastening means comprising a removable clamping element extending over the entire length of the rail and firmly applied against the outer face of the jacket in the direction of the flanks of the rail. Thanks to the fact that the clamping element is removable, it can be removed so as to allow the rail to be released into the channel and easily removed from the latter by keeping the jacket intact. Thus, the latter can be reused when laying a new rail.
- Figures 1 to 5 show a first embodiment of the noise protection device according to the invention.
- the jacket consists of two parts 1 and 2 separated elastic material of parallelepiped right look extending on either side of a rails 3 against the side flanks 4 and 5 of the latter.
- This elastic material is of the same nature as that referred to in the European patent
- This channel 6 is lined on either side of the rail 3 by walls 7 and
- the slot is provided in the channel 6 on the side of the elastic part 1 opposite to the one oriented towards the rail
- the walls 7 and 8 each have a hollow all along their length
- the clamping element 9 is somewhat bulging on the side faces so that this element 9 can engage in the recess 10 of the wall 7 and in a corresponding recess 10 'provided in Part 1 of the jacket.
- the elastic portion 2 enters the recess 11 of the wall 8, under the action of the clamping element 9 which engages in the recess 10 of the wall 7.
- the rail 3 rests on a sole of rigid elastic material 12 located on the bottom of the channel 6.
- the side walls 7 and 8 and the sole 12 rest on their side on a succession of rigid supports 13 spaced also bearing against the face 14 outer walls 7 and 8 opposite to that facing the rail 3.
- Concrete 23 is then cast around the walls 7 and 8 and the sole 12 so as to form the channel 6 containing the rail 3 and the two parts 1 and 2 of the elastic material of the jacket, reserving on both sides rail at regular distances from recesses 21.
- the parts 1 and 2 of the jacket and the clamping member 9 extend to the recess 21 so that in this recess 21 the rail 3 and accessible.
- the recesses 21 give, in particular, access to the rail 3 for cutting it by means of a saw and removing the rail end between two recesses after eliminating the clamping element 9.
- the recesses 21 also provide access to this element 9 so as to be able to push it out of the slot between the wall 7 and the part 1 of the jacket.
- This clamping element 9 is, in particular, manually removed with appropriate material, such as a presser foot or a lever, which is inserted into the space below the clamping element 9 and accessible by the obviously 21.
- FIG. 6 relates to a second embodiment, according to the invention, which is essentially distinguished from the first by the nature of the clamping elements 9.
- the clamping elements 9 comprise Z-shaped bearing profiles 15 threaded onto spaced vertical threaded rods 16 secured by their lower end to a base 17 on which the rail 3 is supported by means of 12.
- the profiles 15 can be moved downwards and thus act on the upper surface of the two. parts 1 and 2 of the jacket to compress and apply them firmly against the flanks 4 and 5 of the rail 3.
- An L-shaped protection profile 19 covers the upper end of the threaded rod 16 and is fixed thereto by a screw 20. Concrete 23 is then cast around the assembly formed by the rail 3 and the jacket 1 , 2 to the level of the upper surface thereof, so as to form a channel 6 containing the rail 3 with the jacket 1, 2.
- Figure 7 relates to a third form of embodiment of the invention which differs essentially from the previous embodiments in that the channel 6 has a trapezoidal cross section in such a way as to gradually narrow towards the bottom thereof and thus to present inclined flat walls 7 and 8.
- the clamping elements 9 may for example be of the same kind as in the second embodiment.
- the clamping element 9 may be formed by a flat, long and narrow profile 15 'fixed by screws 18 on the concrete edges 22 delimiting the channel 6 and protruding relative to the latter. taking support on the upper face of the jacket. As a result of the force exerted by the section 15 'on the parts 1 and 2 of the jacket they are pushed against the lateral flanks 4 and 5 of the rail 3 and the latter is held in position during the passage of a vehicle on the rail.
