Description

The invention relates to an attachment system according to the preamble of claim 1. Furthermore, the invention relates to a road gully, an adapter element and a method.

Road gullies are usually built into on-board gutters. It is known to design or pave board gutters as concrete slabs. The production of such board gutters is expensive and time-consuming. This is why bituminous coverings are increasingly being used on curb gutters. For this purpose, a broader surface layer made of bituminous pavement is produced or laid. Then curbs can be arranged on the cover layer, for example glued on. Alternatively, the curbs can be arranged in front of the surface course and the surface course can then be laid up to the curbs. However, problems arise when installing conventional road gullies in bituminous pavements.

Such a street gully is over CA 2 212 401 C known. The drain comprises a rectangular attachment on which a cylindrical connector is arranged, and a drain body. The attachment is designed in one piece with the socket and is inserted into the drain body.

If the attachment described above is to be rolled into a bituminous surface, when the rectangular attachment is placed on the drain body, the attachment cannot be properly lined with the bituminous surface. Undercuts are created between the attachment and the drain body. The undercuts prevent the bituminous covering from being laid up to the outer contour of the attachment. As a result, the bituminous material of the road surface can no longer be sufficiently compacted. This means that there is no stable substructure that can withstand the traffic loads. As a result, the attachment lowers when a force is applied.

The present invention is therefore based on the object of specifying an attachment system in which undercuts are prevented. A further object of the invention is to specify a road gully, an adapter element and a method.

gelöst.According to the invention, this object is achieved with a view to

• the attachment system by the subject matter of claim 1,
• the road gully through the subject matter of claim 10,
• the adapter element by the subject matter of claim 11 and
• the method by the subject matter of claim 12

solved.

Specifically, the object is achieved by an add-on system for a drain for draining traffic areas, in particular for a street drain. The attachment system comprises an attachment with a frame and a grate which can be inserted into the frame, the frame being at least partially rectangular. The attachment system has a separate adapter element which, in the installed state, is arranged between the frame and a drain body which is at least partially circular in cross section, the adapter element comprising a first area and a second area, the first area being adapted to accommodate the frame, and the second area is adapted to extend at least in sections into the drain body.

The adapter element is a separate component of the attachment system. The adapter element can thus be handled and marketed as an independent component. In other words, the adapter element is releasably connected to the attachment and the drain body prior to assembly. The attachment system is made up of several parts.

When installed, the adapter element is cast in a bituminous material. The adapter element is preferably adapted in such a way that an arrangement between the drain body and the attachment is possible without additional connecting means such as screws or rivets. Alternatively, it is possible to fix the adapter element with additional connecting means.

The adapter element enables a transition from the essentially circular geometry of the drain body to the essentially rectangular geometry of the attachment. The first area of the adapter element is adapted to receive the frame. The second area is adapted to extend into the drain body. In the installed state, the first area is arranged on the upper side of the adapter element. In the installed state, the second area is arranged on the lower side of the adapter element.

In the installed state, the frame is arranged above the adapter element and is preferably rolled into the bituminous material.

In the installed state, the adapter element is arranged, in particular placed, on the drain body. This enables a direct, seamless transition to a cross-sectional geometry that is adapted to the attachment. This makes it possible to use a formwork element which has a geometry that is adapted to the frame of the attachment, in particular a rectangular geometry. The adapter element thus prevents undercuts from occurring. This enables the bituminous pavement to be laid and compacted right up to the outer contour of the attachment. The adapter element and the attachment are preferably only connected to one another by the bituminous material. No additional fasteners such as screws are necessary. The use of the add-on system enables faster assembly.

Preferred embodiments of the invention are specified in the subclaims.

In a preferred embodiment, the first area of the adapter element is rectangular and the second area of the adapter element is cylindrical. This is advantageous because in this way the two areas can be easily adapted to the cross section of the frame and the cross section of the drain body.

In a further preferred embodiment, the frame is arranged axially movable in a direction perpendicular to the road surface in the adapter element. In this way, the frame can be adapted to the level of the surface during assembly in a bituminous surface.

In a further embodiment, the frame has at least one collar which is arranged on an upper edge of the frame when installed, extends away from the frame in a direction parallel to the road surface and is adapted to be rolled, in particular into a bituminous pavement to be rolled in. Preferably, two opposite sides, in particular two opposite transverse sides, of the attachment each include a collar which extend in opposite directions. The collar enables the frame to be rolled evenly into the bituminous surface. The collar is advantageous because it provides a large area for connection to the bituminous pavement.

The collar advantageously has a profile, in particular composed of a plurality of extensions, which is arranged on the exposed surface of the collar in the installed state. The profile increases the safety of the collar against slipping in vehicles and pedestrians. The extensions are preferably designed as knobs. Other shapes that increase safety against slipping are possible.

In a preferred embodiment, a support flange is arranged in the transition area of the two areas, which when installed rests on the drain body. The support flange is advantageous for the arrangement of the adapter element on the drain body, since the adapter element can thus easily be aligned with a flat surface. About that In addition, the support flange prevents bituminous material from getting into the drain body during assembly.

In a further embodiment, the support flange comprises part of the lower surface of the first region of the adapter element and two wings in the shape of a segment of a circle, which are arranged on opposite sides, in particular opposite longitudinal sides. Segment-shaped means that the wings are bounded by an arc and a chord.

In a further embodiment, the first area has longitudinal and transverse sides and the second area is cylindrical, the length of the transverse sides being smaller than the diameter of the second area. This embodiment is advantageous for cuboid attachments which are arranged on a cylindrical drain body.

It is advantageous if the adapter element comprises a metal, a plastic and / or a composite material, in particular polymer concrete. In this way, a suitable material can be selected depending on the requirements. For example, an adapter element made of plastic is advantageous if large quantities are to be produced.

In the context of the invention, a road gully with an attachment system according to one of the preceding claims and a gully body is disclosed and claimed.

Furthermore, within the scope of the invention, an adapter element for a drain for draining traffic areas for rolling into bituminous pavements is disclosed and claimed, the adapter element comprising a first area and a second area, the first area being adapted to receive a frame, and the second area is adapted to extend into a drain body at least in sections, wherein a support flange is arranged in the transition area of the two areas, which rests on the drain body in the installed state.

The Figures 1 to 3 show an attachment system 10. The attachment system 10 comprises an attachment 11 and an adapter element 14. The attachment system 10 is suitable for use in road gullies.

The attachment 10 has a frame 12 and a grate 13. The grate 13 is inserted into the frame 12. The frame 12 is rectangular and has longitudinal and transverse sides.

A collar 18 is arranged on the transverse sides of the frame 12. The collar 18 is arranged on an upper edge of the frame 12 in the installed state. The collar 18 extends away from the frame 12. More precisely, the collar 18 is arranged vertically on the transverse sides in such a way that the collar 18 is parallel to a road surface in the installed state.

The collar 18 has a profile 19. The profile 19 comprises several extensions arranged in rows. The extensions are arranged vertically on the collar 18. The frame 12 and the collar 18 have a border. The border extends in the direction of the profile and is flush with the profile in a plane.

The adapter element 14 has a first area 16, a second area 17 and a passage opening.

The first area 16 is rectangular. The length ratio of the longitudinal and the transverse sides of the inner contour of the first area 16 corresponds to the length ratio of the longitudinal and transverse sides of the outer contour of the frame 12. The inner contour of the first area 16 is larger than the outer contour of the frame 12 and adapted to the frame 12 to include. Other contours are possible.

The second area 17 is circular. More precisely, the second area 17 is cylindrical. The second area 17 is adapted to extend into a cylindrical drain body 15 in the installed state. The outside diameter of the second area 17 is smaller than the inside diameter of the drain 15. Other contours of the second area 17 and the drain body 15, which are adapted to one another in such a way that the second region 17 extends into the drain body, are possible.

The first and second areas 16, 17 extend essentially perpendicular to the road surface. The diameter of the cylindrical second region 17 is greater than the distance between the opposing longitudinal sides of the frame 12 from one another. The two areas 16, 17 are connected to one another by an area which extends parallel to the road surface.

A support flange 20 is arranged in the transition area between the two areas 16, 17. The support flange 20 is formed from the surface that connects the first and second areas 16, 17 to one another and two wings in the shape of a segment of a circle, which are arranged on the longitudinal sides. The wings in the shape of a segment of a circle each have a contour which is delimited by an arc of a circle and a chord of a circle. The circular chord extends in the longitudinal direction of the attachment 11. The circular arc extends away from the adapter element 14. In other words, the circular arc of the support flange 20 protrudes.

The collar 18, which is arranged on the frame 12 of the attachment 11, enables the attachment 11 to be rolled into a bituminous layer. The attachment 11 is arranged on a bituminous material during assembly, so that the frame 12 rests on the bituminous material. The attachment 11 is then rolled in. The collar 18 sinks into the bituminous material. After rolling in, the border is flush with the bituminous material. The compaction is preferably carried out by rolling. Alternatively, other methods are possible, such as shaking or tamping. The collar 18 is visible after rolling and forms a surface that can be driven over.

The profile, which is arranged on the collar 18 on the surface that is visible in the installed state, increases the safety against slipping, for example when wet. Furthermore, the border forms a kind of tub, which is advantageous for the drainage of rainwater.

The adapter element 14 forms an interface between the drain body 15 and the attachment 11. The attachment 11 is arranged in the first area 16 in the installed state. The second area 17 extends into the drain body 15. For this purpose, the first area 16 of the adapter element 14 is preferably rectangular or includes a rectangular contour. For this purpose, the second region 17 is preferably of cylindrical design or comprises a cylindrical contour. Alternatively, other shapes or contours are possible. The adapter element 14 forms a transition from the attachment 11 to the drain body 15.

The support flange 20 enables the adapter element 14 to lie tightly on the drain body 15. Furthermore, the adapter element 14 can be arranged straight on the drain body. Furthermore, the support flange prevents bituminous material from getting into the drain body 15 during assembly and contaminating it. Alternatively, it is conceivable that the adapter element 14 is connected to the drain body 15 by the support flange 20 with screws or rivets.

In the Figures 4 to 14 an embodiment for the assembly of the embodiment of an attachment system described above is shown.

In Fig. 4 a drain body 15 is shown, which is arranged in a support layer 29. The adapter element 14 is arranged, in particular placed, on the drain body 15 and the support layer 29, so that the second region 17 of the adapter element 17 extends into the drain body 15.

Then the adapter element 14 is as in Fig. 5 shown, covered with a first cover element 21.

In Fig. 6 the binder layer 21 made of bituminous material is first applied so that the adapter element 14 with the first cover element 21 is completely surrounded by the binder layer 21. Other materials that can be used in the asphalt construction are possible.

In the Figures 7 and 8 it is shown how, after the binder layer 21 has been applied, the first cover element 21 is removed again. For that will the binder layer 21 is removed from the first cover element 21 and a first step 23 is formed around the attachment 11. A formwork element 24 is arranged on the exposed adapter element 14. A gap is formed between the formwork element 24 and the binder layer 21. The gap is filled flush with the bituminous material of the binder layer 22.

Next, as in Fig. 9 shown, the attachment 11 inserted into the adapter element 14 and rolled into the binder layer 21.

The attachment 11 is then covered with a second cover element 26 and a cover layer 27 made of a bituminous material is applied (cf. Fig. 10 and Fig. 11 ). The bituminous material of the cover layer 27 has a finer grain size than the bituminous material of the binder layer 22.

In the Figures 12 and 13th it is shown how the cover layer 27 on the second cover element 26 is removed again and the second cover element 26 is removed. The attachment 11 is then raised and lined with the bituminous material of the top layer.

Finally, the attachment 11 is in the top layer, as in Fig. 14 described, rolled in. After rolling in, the surface of the attachment is essentially flush with the road surface.

The attachment 11 is rolled into the binder layer 22 and into the cover layer 27 in order to produce a good substructure. As a result, the binder layer 22 and the cover layer 27 are compressed up to the frame 12 of the attachment 11.

The first and the second cover element 21, 26 have different dimensions. The dimensions of the first cover element 21 are adapted to the adapter element 14 and the dimensions of the second cover element 26 are adapted to the attachment 11. As a result, not too much or too little bituminous material is removed when the cover elements 21, 26 are removed.

The different layers have different grain sizes. The top layer has a finer grain size than the binder layer. Other grits are possible. The base course can be made of a bituminous material or concrete. In addition to bituminous materials, tar-based materials are also possible.
