Description

[0001] The invention relates to an attachment system according to the preamble of claim 1. Furthermore, the invention relates to a street drain and a method. An adapter element of the Attachment system according to claim 1 is known for example from DE 296 01 230 U1.

[0002] Street drains are usually installed in curbs. It is common practice to construct curbs as concrete slabs or to pave them. The construction of such curbs is expensive and time-consuming. Therefore, bituminous surfaces are increasingly being used for curbs. For this purpose, a wider surface layer made of bituminous surface is produced or laid. Curbs can then be arranged on the surface layer, for example, glued on. Alternatively, the curbs can be arranged in front of the surface layer and the surface layer then laid up to the curbs. However, problems arise when installing conventional street drains in bituminous surfaces. Such a street drain is known from CA 2 212 401 C. The drain comprises a rectangular attachment to which a cylindrical nozzle is arranged, and a drain body. The attachment is formed as a single piece with the nozzle and is inserted into the drain body.If the above-described extension is to be rolled into a bituminous surface, the extension cannot be properly supported with the bituminous surface when the rectangular extension is placed on the drain body. Undercuts will form between the extension and the drain body. These undercuts prevent the bituminous surface from being laid all the way to the outer contour of the extension. As a result, the bituminous material of the road surface can no longer be sufficiently compacted. This means that there is no load-bearing substructure that can withstand traffic loads. As a result, the extension sinks when subjected to force.

[0003] An adapter typically used in street gullies is described, for example, in the aforementioned DE 296 01 230 U1. DE 296 01 230 U1 describes an adapter consisting of a pipe section that, when installed, is inserted into a hollow cylindrical concrete shaft, an annular flange arranged at the upper end of the pipe section, and a square frame for a cast attachment frame.

[0004] The present invention is therefore based on the object of providing an attachment system that prevents undercuts. Furthermore, the invention aims to provide a road gully, an adapter element, and a method.

[0005] According to the invention, this object is achieved with regard to the attachment system by the subject matter of claim 1, the street drain by the subject matter of claim 10 and the method by the subject matter of claim 11 solved.

[0006] Specifically, the problem is solved by an attachment 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 that can be inserted into the frame, the frame being rectangular at least in sections. The attachment system has a separate adapter element that, in the installed state, is arranged between the frame and a drain body that is at least partially circular in cross-section, the adapter element comprising a first region and a second region, the first region being adapted to receive the frame and the second region being adapted to extend at least in sections into the drain body.At the upper edge of the frame, in the installed state, a collar is arranged which extends away from the frame, the collar having a profile which comprises a plurality of extensions arranged in rows and perpendicular to the collar, the frame and the collar having a border which extends in the direction of the profile and is aligned with the profile in a plane.

[0007] The adapter element is a separate component of the top-mounted system. This allows the adapter element to be handled and marketed as a standalone component. In other words, the adapter element is detachably connected to the top and drain body before installation. The top-mounted system consists of several parts.

[0008] When installed, the adapter element is cast in a bituminous material. The adapter element is preferably adapted so that it can be positioned between the drain body and the attachment without additional fasteners such as screws or rivets. Alternatively, the adapter element can be secured with additional fasteners.

[0009] The adapter element enables a transition from the essentially circular geometry of the drain body to the essentially rectangular geometry of the top. The first section of the adapter element is adapted to receive the frame. The second section is adapted to extend into the drain body. The first section is arranged on the upper side of the adapter element when installed. The second section is arranged on the lower side of the adapter element when installed.

[0010] When installed, the frame is arranged above the adapter element and is preferably rolled into the bituminous material.

[0011] The adapter element is arranged, in particular placed, on the drain body when installed. This enables a direct, seamless transition to a cross-sectional geometry adapted to the attachment. This makes it possible to use a formwork element with a geometry adapted to the frame of the attachment, in particular a rectangular geometry. The adapter element thus prevents the formation of undercuts. This allows the laying and compaction of the bituminous surface directly up to the outer contour of the attachment. The adapter element and the attachment are preferably connected to each other only by the bituminous material. No additional fasteners such as screws are required. The use of the attachment system thus enables faster installation.

[0012] Preferred embodiments of the invention are specified in the subclaims.

[0013] In a preferred embodiment, the first portion of the adapter element is rectangular and the second portion of the adapter element is cylindrical. This is advantageous because the two portions can be easily adapted to the cross-section of the frame and the cross-section of the drain body.

[0014] In a further preferred embodiment, the frame is arranged in the adapter element so that it can be axially moved in a direction perpendicular to the road surface. This allows the frame to be adjusted to the level of the road surface during installation in a bituminous pavement.

[0015] In a further embodiment, the collar extends away from the frame in a direction parallel to the road surface and is adapted to be rolled into a bituminous surface. Preferably, two opposite sides, in particular two opposite transverse sides, of the attachment each comprise a collar extending in opposite directions. The collar enables the frame to be rolled into the bituminous surface evenly. The collar is advantageous because it provides a large surface area for connection to the bituminous surface.

[0016] Advantageously, the collar has a profile, in particular consisting of several projections, arranged on the surface of the collar that is exposed when installed. The profile increases the collar's safety against slipping, both for vehicles and pedestrians. The projections are preferably designed as studs. Other shapes that increase slipping safety are possible.

[0017] In a preferred embodiment, a support flange is arranged in the transition area between the two sections, which rests on the drain body when installed. The support flange is advantageous for arranging the adapter element on the drain body, as it allows the adapter element to be easily aligned with a flat surface. Furthermore, the support flange prevents bituminous material from entering the drain body during installation.

[0018] In a further embodiment, the support flange comprises a portion of the lower surface of the first region of the adapter element and two circular-segment-shaped wings arranged on opposite sides, in particular opposite longitudinal sides. Circular-segment-shaped means that the wings are bounded by a circular arc and a chord.

[0019] In a further embodiment, the first region has longitudinal and transverse sides, and the second region is cylindrical, with the length of the transverse sides being smaller than the diameter of the second region. This embodiment is advantageous for cuboid-shaped attachments that are arranged on a cylindrical drain body.

[0020] It is advantageous if the adapter element comprises a metal, a plastic, and / or a composite material, especially polymer concrete. This allows a suitable material to be selected depending on the requirements. For example, a plastic adapter element is advantageous when large quantities are to be produced.

[0021] Within the scope of the invention, a street drain with an attachment system according to one of the preceding claims and a drain body is disclosed and claimed.

[0022] Furthermore, outside the scope of the invention, an adapter element for a drain for draining traffic areas for rolling into bituminous surfaces is described, wherein the adapter element comprises a first region and a second region, wherein the first region is adapted to receive a frame and the second region is adapted to extend at least partially into a drain body, wherein in the transition region of the two regions a support flange is arranged which rests on the drain body in the installed state.

[0023] Within the scope of the invention, a method for assembling an attachment system is further disclosed and claimed, in which a) the adapter element is arranged on the drain body such that the second region of the adapter element extends at least partially into the drain body, b) a first cover element, in particular a steel plate, is arranged on the adapter element, c) a binder layer is applied on and around the first cover element, d) the binder layer is removed from the first cover element and then the first cover element is removed, whereby a first step is formed directly around the adapter element, e) a formwork element, which has essentially the same cross-section as the first region of the adapter element, is placed on the adapter element such that a gap is formed between the formwork element and the binder layer and the gap is then filled flush with the bituminous material of the binder layer, f) the attachment is inserted into the adapter element and rolled into the binder layer,g) a second covering element is arranged on the frame and the grate and a covering layer is applied, h) the covering layer is removed from the second covering element and then the second covering element is removed, whereby a second step is formed around the attachment and i) the attachment is then lifted, lined and rolled into the covering layer.

[0024] The invention is explained in more detail below using exemplary embodiments with reference to the accompanying drawings.

[0026] 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 street drains.

[0027] 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.

[0028] 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 when installed. The collar 18 extends away from the frame 12. More precisely, the collar 18 is arranged perpendicularly on the transverse sides such that the collar 18 is parallel to a road surface when installed.

[0029] The collar 18 has a profile 19. The profile 19 comprises several extensions arranged in rows. The extensions are arranged perpendicularly 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 one plane.

[0030] The adapter element 14 has a first region 16, a second region 17 and a passage opening.

[0031] The first region 16 is rectangular. The length ratio of the longitudinal and transverse sides of the inner contour of the first region 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 region 16 is larger than the outer contour of the frame 12 and is adapted to accommodate the frame 12. Other contours are possible.

[0032] The second region 17 is circular. More precisely, the second region 17 is cylindrical. The second region 17 is adapted to extend into a cylindrical drain body 15 when installed. The outer diameter of the second region 17 is smaller than the inner diameter of the drain 15. Other contours of the second region 17 and the drain body 15, which are adapted to one another such that the second region 17 extends into the drain body, are possible.

[0033] The first and second regions 16, 17 extend substantially perpendicular to the road surface. The diameter of the cylindrical second region 17 is greater than the distance between the opposite longitudinal sides of the frame 12. The two regions 16, 17 are connected by a surface that extends parallel to the road surface.

[0034] A support flange 20 is arranged in the transition area between the two regions 16, 17. The support flange 20 is formed by the surface that connects the first and second regions 16, 17 and two circular-segment-shaped wings arranged on the longitudinal sides. The circular-segment-shaped wings each have a contour defined by a circular arc and a chord. The 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.

[0035] 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. During installation, the attachment 11 is positioned on a bituminous material so that the frame 12 rests on the bituminous material. The attachment 11 is then rolled into place. The collar 18 sinks into the bituminous material. After rolling, the border is flush with the bituminous material. Compaction is preferably performed by rolling. Alternatively, other methods are possible, such as vibrating or tamping.

[0036] The collar 18 is visible after rolling and forms a surface that can be driven over.

[0037] The profile, which is arranged on the collar 18 on the surface visible when installed, increases safety against slipping, for example, in wet conditions. Furthermore, the border forms a kind of trough, which is beneficial for rainwater drainage.

[0038] The adapter element 14 forms an interface between the drain body 15 and the attachment 11. The attachment 11 is arranged in the first region 16 when installed. The second region 17 extends into the drain body 15. For this purpose, the first region 16 of the adapter element 14 is preferably rectangular or has a rectangular contour. The second region 17 is preferably cylindrical or has 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.

[0039] The support flange 20 enables the adapter element 14 to rest tightly on the drain body 15. Furthermore, the adapter element 14 can be positioned straight on the drain body. Furthermore, the support flange prevents bituminous material from entering and contaminating the drain body 15 during installation. Alternatively, it is conceivable for the adapter element 14 to be connected to the drain body 15 via the support flange 20 using screws or rivets.

[0040] In the Figures 4 to 14 An example of how to assemble the above-described embodiment of an attachment system is shown.

[0041] 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.

[0042] The adapter element 14 is then inserted as shown in Fig. 5 shown, covered with a first cover element 21.

[0043] In Fig. 6 First, the binder layer 21 made of bituminous material is 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 asphalt construction are possible.

[0044] In the Figures 7 and 8 It shows how, after the binder layer 21 has been applied, the first covering element 21 is removed again. For this purpose, the binder layer 21 is removed from the first covering 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.

[0045] Next, as in Fig. 9 shown, the attachment 11 is inserted into the adapter element 14 and rolled into the binder layer 21.

[0046] Subsequently, the attachment 11 is covered with a second covering element 26 and a covering layer 27 made of a bituminous material is applied (cf. Fig. 10 and Fig. 11 ). The bituminous material of the covering layer 27 has a finer grain size than the bituminous material of the binder layer 22.

[0047] In the Figures 12 and 13 It shows how the covering layer 27 on the second covering element 26 is removed again and the second covering element 26 is removed. Subsequently, the attachment 11 is lifted and lined with the bituminous material of the covering layer.

[0048] Finally, the attachment 11 is inserted into the top layer as shown in Fig. 14described, rolled in. After rolling in, the surface of the attachment is essentially flush with the road surface.

[0049] The top layer 11 is rolled into the binder layer 22 and the surface layer 27 to create a good substructure. This compacts the binder layer 22 and the surface layer 27 up to the frame 12 of the top layer 11.

[0050] The first and second cover elements 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. This ensures that neither too much nor too little bituminous material is removed when removing the cover elements 21, 26.

[0051] The various layers have different grain sizes. The surface course has a finer grain than the binder course. Other grain sizes 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. List of reference symbols
