Description

In DK 175725 B1

The invention relates to a modular wall. especially a noise shield according to the preamble

of claim 1, for installation along, for example, roads or railways. IN

From EP 0213521 a modular wall is known in which two adjacent screens are adjacent

elements in the form of transparent glass panels are clamped against a post with a plane I

5 flat. A disadvantage of this system is that high accuracy is required with respect to the input

the position of the posts is burdened, and they must be completely vertical if the cutting itself

but must stand completely vertical. IN

From US 4,214,411 a modular wall is known in which the screen elements are made of I

flexible plastic and is provided with curved side edges for attachment around I

10 vertical bars. This system also requires special care when setting up the posts. IN

From WO 98/01625 a noise shield according to the preamble of claim 1. is known.

this noise shield is that the posts have a relatively complex profile with longitudinal groove I

for recording mounting means. These tracks also mean that the posts must be positioned

correct with respect to rotation about the vertical axis of the post during alignment I

15 for the screen itself. IN

The object of the invention is to provide a new and improved modular wall in which:

With simple means a quick and safe installation can be achieved. IN

The wall system according to the invention is peculiar in that the post has a circular cross section, and

the mounting means is formed with a circular opening corresponding to the cross-section of the post so that you

The mounting means can be rotated about the post for fixation in any I

angular position, and the screen element comprises at least one, in the screen mounted condition, I

a horizontal extending slot and the free end of each arm of the mounting member is arranged

to be able to engage and secure in this slot. With such a panel system, I

with very simple means a quick and simple installation, the combination of the rotatable I

25 mounting means and slots ensure relatively large tolerances with respect to arrangement I

I DK 175725 B1 I 2 I of the post. Even if the pole is not completely vertical, the screen ends can be mounted vertically. The poles themselves are very simple and inexpensive to manufacture, simply having a round cross section.

According to the invention, the mounting means may comprise clamping means for securing the mounting means around the post at any angular position. Thus, when the screen during installation has been correctly positioned, the structure is fixed by tightening these clamping means.

According to the invention, the slots may be located at the vertically extending edges of the screen element, whereby one and the same post can be used for mounting two adjacent screen elements adjacent to each other.

According to a convenient embodiment, each screen member is rectangular and provided with a spring along the vertically extending edge of one of the screen elements and a groove along the other vertically extending edge. During the assembly process, the spring H can be inserted into the groove and ensure correct positioning of the shield elements relative to each other, just as the entire module wall will run uninterrupted, ie. the noise prevents H from penetrating through spaces between the individual screen elements.

H According to the invention, the shield element may comprise a plate element, a condition in the condition of the shield element H, a vertical groove profile element, a vertical spring profile element and at least two horizontal clamping profile elements, which clamping profile elements are provided with the slots. Hereby, it can be achieved that any differences between the thermal expansion coefficients of the plate element and the clamping profile elements do not cause damagingly large voltages.

According to a preferred embodiment, the clamping profile element may comprise a horizontal protruding flange portion comprising the slots. This is a particularly simple embodiment of the invention.

In DK 175725 B1 [according to a particularly convenient embodiment of the wall system according to the invention, the mounting means for two adjacent screen elements can be mounted on the same post, which is located at two adjacent vertically extending edges on two screen elements. Such a system uses a minimum number of posts.

According to the invention, the plate element may consist of a transparent material, e.g. glass or plastic, especially acrylic plastic. This is particularly appropriate, as the view from a road or railway line is not unduly limited, and the view from buildings adjacent to the road / rail is not unduly restricted.

Alternatively, the plate member may consist of a sound-absorbing cassette, which may consist of two 10 perforated aluminum sheets, between which a sound absorber, e.g. mineral wool, is located.

The invention will now be explained in more detail with reference to the preferred embodiment shown in the drawing, in which: FIG. 1 shows a panel system according to the invention,

FIG. 2 is a top view of the panel system according to the invention;

FIG. 3 is a perspective view of the section shown in FIG. 2 and I

FIG. 4 is a perspective view of the panel system shown in FIG. 1. IN

The modular wall shown in FIG. 1 according to the invention consists as main elements I

of some screen elements 1, only three of which are shown here, some posts 2 and mounting members I

20 for attaching the shield elements 1 to the posts 2. The wall system I shown in Figure 1

in the illustrated embodiment is designed as a noise shield for noise shielding of a road and I

I DK 175725 B1 | I 4 I is mounted along the edge of a bridge deck 20. However, the noise shield can be mounted either on terrain or on a support wall.

In Figure 2, a section of the noise screen shown in Figure 1 is shown from above. It can be seen how two adjacent screen elements 1 are mounted by means of mounting means 3 to a post 5. The post 2 has a circular cross section and the mounting means 3 has a circular opening I corresponding to the cross section of the post and thus can be clamped about the post at any angular position. Each mounting member 3, in the embodiment shown, consists essentially of two ring halves 3a and 3b, which can be screwed around the post by two bolts 7 joining the two ring halves at their respective ends. One ring half 3a is provided with a protruding arm portion 4, the free end of which is provided with a

ring part 15. The ring part 15 has a threaded hole for receiving a mounting bolt 7, by means of I

of which the shield elements 1 can be fixed to the protruding arm portion 4, as will be described below. The shielding elements are essentially made up of plate elements 14, which may consist of e.g. transparent glass or plastic sheets or of sound-absorbing cassettes, vertically extending profile elements 11, 12, horizontal clamping profiles 10 H and clip profiles 13. The clip profiles 13 are known per se and can be clipped to the in-H tension profiles and thereby clamp the plate elements 14 . As can be seen in Figure 2, the plate elements 14 extend beyond the vertical profiles 11, 12. This is an advantage, since the plate elements 14 may conveniently be made of transparent acrylic plastic 20, whose temperature expansion coefficient differs in part from the temperature expansion coefficient of the materials, e.g. aluminum to which the profile elements 10, 11, 12 are made

The clamping profile elements 10 have a horizontally extending flange portion 6 which is provided with a longitudinally extending slot 5. This slot is used for attachment 25 of the shield element 1 to the free end of the mounting arm 4. of the mounting member 3, a bolt H 7, the head of which is wider. Thus, than the slot 5, it can be passed from one side through the slot H 5 and screwed into the threaded hole in the ring portion 15 of the protruding arm part 4. As can be seen in Figure 2, the mounting member 3 retaining the screens on the left in the figure is - 175 · DK 175725 B1 element 1, located above the flange portion of the clamping profile 10, whereas the mounting member 3, which retains the shield element at the right of the figure, is located below the flange portion of the clamping profile 10.

The vertical profile of one of each screen element 1 (element 12 is formed with an I)

5 feather 8. whereas the second of each screen element 1 vertically extending profile element 11 I

is designed with a groove 9. During mounting, a screen element spring 8 can thus grip I

into the side 9 of the standing screen element and thereby isolate the noise and noise

the gap between two screen elements. The feather / groove connection also contributes to the management of I

the screen elements relative to each other during assembly of the noise shield. IN
