Procedure, in particular
Road or bridge drain

The invention relates to a drain, in particular for road or bridge drainage, with opposite one Lower part height-adjustable upper part, which has the inlet and a downwardly protruding nozzle and means a retaining clip which surrounds the nozzle and can be locked on it by a force fit or form fit can be locked.

Such a sequence is known, for example, from US Pat. No. 1,873,275. The well-known

management forms of such processes mainly have the Disadvantage that the retaining disk is only used to lock the upper part during the installation of the process, but can hardly absorb or transfer any load from above. The transfer of the load from the upper part to Rather, the lower part usually takes place over the road surface, which consists, for example, of bitumen, as a result of which frequent damage to the surface of the road around the drain occur around. Another disadvantage is that

^! inclination and lateral displacement of the upper

part of the known processes is hardly possible. Through this

the installation of the processes and an adaptation of the upper part to a possible slope of the road surface is essential difficult.

The object of the invention is to remedy these disadvantages and to create a system that is as inexpensive and easily adaptable as possible and to create a built-in drain, especially for road or bridge drainage, of the following Requirements are met: The upper part must be rotatable with respect to the lower part of the drain during the installation time be designed; the upper part in which the grate is located must be attached to a road higher or lower

ceiling adaptable, i.e. adjustable in height. Farther the upper part has to be attached to the road inclines and curves be adaptable due to inclines during installation. After installation, the upper part must be in its be fixed in the correct position, if possible in such a way that it takes the entire load occurring during operation on the retaining plate on the lower part and thus on the construction

ι concrete can transfer the road or bridge.

According to the invention, a sequence of the type mentioned above is characterized in that the retaining disk is clear in its Width is adjustable. As a result, it can j frictionally so firmly with the upper part of the drain

j are connected that they are also the greatest loads on the

! Can transfer lower part. This applies in particular if

if like; '3 a preferred feature of the invention The outer surface of the connecting piece of the upper part, on which the retaining disk engages, tapers conically downwards. In this case, the power transmission is achieved not by frictional engagement, but by positive engagement. One Loosening of the retaining washer that is tightened on the nozzle counteracts the pressure load »The conical design of the nozzle is also part of the manufacture of the Upper part of the process as a cast body advantageous.

The retaining disk preferably consists of an axially extending collar and a radially extending flange. The arrangement is preferably made so that the flange of the retaining disk of the counter flange to a flange of the Drainage part is, and there is also the advantageous possibility of an insulating layer between the flanges clamp it in place and fasten it to the drain in a watertight manner.

Advantageously, the inner surface of the axial collar of the retaining disk also runs conically, in particular it has the same conicity as the outer surface of the connecting piece of the upper part. This is the static friction between the retaining washer and the connecting piece improved and the surface loading reduced.

The retaining disk is preferably designed to be resilient in the radial direction. Because a wide flange is a radial one Makes springs impossible, the flange advantageously has a number of recesses that go so far reach up to the federal government so that the retaining plate can spring at these points. The resilient design of the retaining washer makes it possible to bring about their adjustability in such a way that the retaining disc in the circumferential direction one Has interruption with a clamping device in their

Width is changeable. By tightening a single clamping device, for example a screw, the retaining washer on the nozzle and thus the final height of the Drain upper part can be adjusted.

The retaining disk is advantageously fastened to the lower part by flange screws which extend through the recesses of the flange extend. The recesses are advantageously dimensioned so wide that the retaining disk with inserted flange screws rotatable and displaceable to a limited extent relative to the lower part is.

The recesses can advantageously be designed as drainage holes for the drain at the same time. These Drainage holes allow the water that has penetrated into the street via the insulation layer to be drained away, thereby a destruction of the road surface by frost effects in the vicinity of the drain is prevented.

According to a further preferred feature of the invention, the collar of the retaining disk is designed and in its axial height dimensioned so that a tilting of the upper part relative to the retaining plate is possible to a limited extent is. The inner surface of the collar of the holding

washer convex. This enables the upper part of the drain to be adapted to a slope at the end of the road CKt- possible.

The sequence according to the invention is preferably further characterized in that the retaining disk is designed in this way Is that its inner surface resting on the socket of the upper part is below the level of the insulating layer or the road or bridge concrete is arranged. In this way, the thickness of the the seal or the road surface to be applied to the concrete, i.e. the distance between the inlet and choose the concrete as small as you like. Depending on the circumstances, you can completely adjust the overall height of the drain reduce significantly.

The old disk advantageously rests on a support of the lower part which is below the level the insulating layer or the road or bridge concrete is arranged. There is the possibility of the Forces acting on the drain from the upper part directly to the lower part without the interposition of the seal transferred to. This leads, on the one hand, to a particularly good retention of the upper part and, on the other hand, to a Relief and thus a protection of the seal.

The support is preferably the base of a washer which surrounds the upper part in a ring shape and the retaining washer receiving recess of the lower part formed.

The entire process becomes a compact one

eny
That is, the individual parts of the MÜS can also be manufactured with little manufacturing effort. With this arrangement, the shape of the retaining disk can be adapted to the formation of the recess.

Another advantageous feature of the process according to the invention consists in the fact that when using of a lateral drainage pipe, the upper part has a recess on the side adjacent to the lateral drainage pipe having. This recess offers the possibility of the side drainpipe in the simplest possible way to clean, and also creates a facilitated water drainage towards the side drainage pipe. Such a recess also brings its advantages to use when it is adjustable in height Drains that have a side drain pipe is used. In particular, this is then FaJ1 if the upper part is relatively far into the lower part protrudes. In the process according to the invention, such conditions are given above all, if the inner surface of the retaining disc resting on the neck of the upper part is below the level of the Insulating layer is arranged.

Fig. 3 shows a section through a second embodiment.

The sequence shown consists of an upper part 1 and a lower part 2. The upper part 1 essentially forms the frame for the inlet grate J5 and has a nozzle 4 protruding downward. Inside the upper part 1 hangs under the inlet grate J ^θ ^ ^η dirt bucket 5 · The lower part 2 surrounds the nozzle 4 of the upper part at a distance and narrows in the shape of a funnel to a drainage nozzle 6. The lower part 2 is firmly in the (not shown) concrete of the road or embedded bridge.

to be transferred directly to the lower part and thus to the concrete, without the road or bridge covering layer IJ, which is flush with the upper part 1, which z «.B. consists of bitumen, to load, a retaining disk 7 is provided. This is in Fi ^. 2 shown in plan view. It consists of an axially extending collar 8 and a radial flange 9 and has an interruption Io in the circumferential direction, which can be pulled together by a clamping means, here a clamping bolt 11 extending through abutment 12, so that the clear width of the retaining disk can be changed . In the flange 9, several (in this example four) notches or recesses 15 reaching up to close to the collar 8 are provided in order to enable a resilient deformation of the collar at these points when the screw 11 is tightened.

As can be seen from FIG. 1, the retaining disk 7 rests against the connector 4 of the upper part 1, is clamped there by tightening the clamping screw 11 and is supported with its flange 9 against a corresponding flange 14 of the lower part 2. An insulating layer 15, for example made of roofing felt or plastic, can be clamped between the flanges 9 and 14. The fastening of the retaining plate ¹ J on the lower part 2 is carried out by screws 16, which are through the

Recesses Ij5 are screwed through into the plan 14 of the lower part. The recesses I ^ are dimensioned wider than the screws 16, so that the retaining disk J together with the upper part 1 can still be rotated or displaced to a limited extent relative to the lower part 2 even when the screws are inserted.

It can be seen from the drawing that the nozzle 4 of the Upper part 1 tapers conically downwards. For this reason there is a certain setting of the clear The width of the retaining disk 7 clearly defines the height of the upper part 1. The inner surface of the collar 8 of the retaining disk 7 preferably also approximately corresponds to the conicity of the connecting piece 4. However, an (from the drawing (not visible) slight convexity of the inner surface of the collar 8 is advantageous because then the upper part 1 with respect to the retaining disk 7 is tilted to a limited extent and can thereby be adapted to a slope of the road surface.

The drain is assembled as follows: After the lower part 2 in the Konstriüctionsbeton the street or Bridge has been firmly set in concrete, becomes the retaining washer

and then the upper part 1 of the drain into the lower part 2 used. Here, the upper part 1 can be rotated so that the mostly rectangular grate 3 with the roadside runs parallel. The upper part can therefore be rotated before the final installation in the lower part. This is where the top is 1 and thus also the grate 3 with the help of the retaining plate 7 in its height corresponding to the height of the road surface created and further adapted by tilting with respect to the retaining plate 7 to a slope of the road surface. Then, by tightening the retaining washer 7, the Fixed upper part Another limited horizontal shift for precise adjustment of the upper part of the drain can be done before the final tightening of the screws 16. When the upper part is finally adjusted and fixed, wiri der road surface 17 finished poured.

In the modified embodiment of Figure 3 is the holding disk 7 is designed such that its inner surface, which rests against the connection piece 4 of the upper part 1, is below the Nivear "17, which corresponds to the level of an insulating layer (not shown) 15 corresponds to FIG. 1, is arranged. The surface is also at this level the road or bridge concrete into which the lower part 2 of the drain is embedded. As shown in Fig. 3

occurs, there is such an arrangement
Possibility to insert the upper part 1 very deeply into the lower part
2 and thus the drain to very thin ones
Adapt layers of a road surface.

The retaining disk rests on a support 18 of the
Lower part 2, which is below the level 17 of the
Roof insulation layer 15 or the road or bridge concrete is arranged. The forces that the upper part absorbs can therefore be transmitted directly to the lower part without the interposition of the insulating layer.
Independently of this function, the insulating layer can also be clamped between the holding disk and the lower part. It is not burdened any further and is therefore spared. The support 17 forms the bottom
an annular recess of the lower part 2, in which the retaining disk 7 is received.

In the illustrated embodiment, instead of a vertical drainpipe a side drainpipe

19 used. To clean this pipe with no effort too
can, even when the upper part 1 protrudes relatively far into the lower part 2, is in the upper part
the side facing the drain pipe 19 has a recess

20 provided. This recess also facilitates the rest the drainage of the water in that direction.
