SELF-LEVELING ROAD DEVICE AND METHOD

ASSEMBLY OF SUCH A DEVICE

The present invention relates to a self-leveling road system, comprising a guide frame for mounting on a manhole, a guided frame for telescopically mounting in the guide frame and for receiving a buffer and a sealing element for sealing between the frames. .

The present invention also relates to a method of assembling such a device.

Such self-leveling road devices are for example described in FR 2 811 690. A disadvantage of these devices is that in reality, in the state where the device is integrated in the roadway, the sealing element rarely fulfills its sealing function.

When mounting the device, the guided frame is first introduced into the guide frame and slid completely into it. Then there are road works where heavy vehicles maneuvering on the device load the sealing element. After that, when we want to place the guided frame in its final position, by lifting the guided frame, the sealing element is typically torn or torn from the guide frame. This sealing element is rarely replaced, as we do not need this element to properly install the frames. On the one hand the guide frame rests on the gaze and on the other hand, the guided frame typically rests on the asphalt. At the time of deposition, on site, we no longer take care of this sealing element.

The objective of the invention is to provide such a device in which in the assembled state, the sealing element can still fulfill its sealing function.

According to the invention, this objective is achieved with a self-leveling road system, comprising:

- a guide frame for mounting on a manhole;

BE2016 / 5715

- a guided frame to mount telescopically in the guide frame and to receive a pad;

a sealing element for sealing between the frames;

- And a ring for mounting on the guide frame or the guided frame, to tighten the sealing element between the ring and the frame to which the ring is mounted in the assembled state.

As according to the invention, the sealing element is clamped between a ring and a frame of the device, it can withstand greater loads and it is less easy to tear off or tear it.

As a sealing element, it is possible for example to advantageously use an EPDM gasket of 80 shore for example. Alternatives for such a sealing element are conceivable.

The frames, the ring and the pad are preferably made of cast iron but could also be made of other suitable materials.

In the assembled state, the ring of a preferred device according to the invention is mounted on the guide frame. Less advantageously, it could be mounted on the guided frame.

A preferred device according to the invention comprises fixing elements for fixing the ring on the corresponding frame.

More specifically, these fastening elements can for example comprise bolts.

The sealing element of a device according to the invention preferably comprises several projections around its contour. In this case, in the assembled state, the mentioned fastening elements are preferably arranged at the height of these projections. Even better, the fastening elements which are arranged at the height of these projections are mounted through these projections.

BE2016 / 5715

When the sealing member includes such projections, the frame on which the ring is mounted preferably also includes projections on its outline, corresponding to the projections of the sealing member, and the ring preferably includes projections on its outline, also corresponding to the projections of the sealing element.

The ring of a device according to the invention preferably comprises a flange for receiving the sealing element, so that it is easy to position the sealing element relative to the ring.

Even better, in the assembled state, this edge of the ring projects beyond the edge of the frame to which the ring is mounted, so that it is easy to position the ring relative to this frame.

The object of the invention is also achieved with a method of assembling such a self-leveling road system by means of a ring with a mentioned flange where the sealing element is applied to the ring against this flange. , before mounting the ring on the guide frame or the guided frame with the sealing element between the ring and this frame.

The present invention will now be explained in more detail by describing preferred devices and methods according to the invention. This description is only intended to provide an illustrative example of the invention and to reveal other advantages and details of the devices and methods according to the invention, and it should in no way be interpreted as a limitation of the field of use of the invention or patent rights claimed in the claims.

Figure 9 is a sectional view of the device of Figure 1, with a maximum inclination.

In the figures, a particular case of a self-leveling road system (1) according to the invention is shown.

This device (1) comprises a guide frame (2), a guided frame (3), an articulated pad (4), two seals (5, 13), a ring (6) and bolts (7).

In the device (1) illustrated, the frames (2), the buffer (4) and the ring (6) are made of cast iron, the seals (5, 13) are made of EPDM and the bolts (7) are made in steel.

The guided frame (3) slides into the guide frame (2) and rests on the asphalt 25 with its edge (8).

This guided frame (3) receives the articulated buffer (4). This articulated buffer (4) includes a seal (13) over the entire contour of its installation.

The guided frame (3) illustrated is round, but could also take other forms.

BE2016 / 5715

The base (9) of the guide frame (2) comes to rest on the inspection chamber. The illustrated guide frame (2) comprises a square base (9). It could also include a round base.

A seal (5) which is made in one piece is blocked between on the one hand the guide frame (2) and on the other hand the ring (6). The illustrated ring (6) is made in two parts. To fix this seal (5) between the guide frame (2) and the ring (6), this seal (5), this frame (2) and this ring (6) comprise projections (10, 11) corresponding to their contour. Bolts (7) are mounted through these projections (9).

To facilitate the mounting of the ring (6) and the seal (5), the ring (6) comprises a flange (12) which on one side receives the seal (5) and on the other side projects beyond the edge (14) of the guide frame (2).

To assemble the device (1) we first put the seal (5) in the ring (6) and then put the ring (6) with the seal (5) on the guide frame (2), with the edge of the ring (6) projecting from the edge (14) of the guide frame (2). They are fixed together with the bolts (7), tightening the joint (5) between the guide frame (2) and the ring.

The entire guide frame (2) with the ring (6) and the seal are placed directly on the inspection chamber. The guided frame (3) is then slid into the guide frame (2) at its lowest level.

When road works are finished, the guided frame (3) is positioned in the road surface. The seal (5) deforms as a function of the inclination of the guided frame (3) relative to the guide frame (2).

When the guided frame (3) is at its highest level, as illustrated in Figures 2 and 7, the guided frame (3) is in full support on the asphalt.

When the guided frame (3) is at its lowest level, as illustrated in FIG. 8, part of the guided frame (3) descends into the inspection chamber.

In the different positions illustrated, sealing is always guaranteed.
