Description

Description

The invention relates to a street drain with a base body that has a sludge chamber or a floor drain and a sludge bucket, as well as with a support ring on which an attachment can be arranged.

According to the German standard DIN 4052 "Concrete parts and buckets for street drains", the street drains have a concrete part designed as a container with an outlet pipe arranged at a certain height above the floor of the street drain.

The street drains can also be provided with a base and an outlet pipe arranged in the base area. In this case, a sludge bucket is arranged in the street drain.

What these street drains have in common is that a support ring rests on the base body of the street drain. An attachment is placed on the support ring. The support ring absorbs the force or load that acts from above on the attachment or directly on the support ring and transfers the load to the base body of the street drain.

These concrete road gullies have the disadvantage that they are very difficult to handle during installation because they have a very high dead weight. In addition, the high dead weight also makes it difficult to transport them from the manufacturer to the company that installs the road gullies and from the company that installs the road gullies to the final location of the road gully.

In addition, these road drains cause problems in storage, as their heavy weight also causes problems.

According to the state of the art (EP 0 178 829 A2), street drains are known which are made in one piece from plastic. The street drain known from this publication has the outlet pipe in the upper third of the main body of the street drain. A guide surface is arranged in front of the outlet pipe, which reaches up to the area of the highest water level in the street drain. This design is intended to prevent odor nuisance from the street drain.

This state-of-the-art road gully is relatively complex in construction due to the guide surface and a closable opening arranged in the guide surface.

The technical problem underlying the invention is to provide a street drain that is simple in terms of construction and is also easy to handle.

This technical problem is solved by the features of claim 1.

Because the base body of the street drain is made of plastic, it has a low weight. The support ring is arranged independently of the base body of the street drain in the ground and/or concrete in such a way that the support ring at least partially encloses the upper area of the street drain without pressure. As a result, the support ring absorbs the entire pressure applied to the support ring from above.

acting force (road traffic loads, weights of the frames and gratings) and transfers this to the concrete and the ground in which the support ring is preferably arranged. The base body of the street drain is no longer exposed to any load. This makes it possible to design the base body in such a way that it no longer performs a load-bearing function, but only has the function of collecting the water and mud flowing into the street drain. This means that the base body of the street drain can be designed simply. The structure of the base body of the street drain is only subject to the condition that the base body is arranged in the ground in a self-supporting manner, i.e. that no vertical loads or no traffic loads acting directly from above act on the base body.

The support ring is preferably arranged in such a way that it encloses the upper area of the street drain without pressure. For this purpose, the inner diameter of the support ring is larger than the outer diameter of the base body.

To simplify assembly, the support ring is designed in several parts according to the invention. A preferred embodiment is the two-part design. If the support ring is made of concrete, this makes it easier to handle. On the one hand, only the individual parts of the support ring need to be transported. On the other hand, the parts of the support ring are arranged individually around the base body, which is easier than placing a one-piece support ring.

It is advantageous for the support ring to be reinforced with iron, steel and/or plastic fibres. This gives the support

bearing offers greater stability and therefore greater resistance to breakage.

The support ring can also advantageously be made of plastic.

The ends of the parts of the support ring are designed in such a way that the parts of the support ring can be positioned relative to one another in such a way that the parts of the support ring form an upper level on which the attachment or the grate rests flat. For this purpose, the ends are advantageously designed in a stepped shape or with dovetail-shaped and/or groove-shaped ends.

The base body is advantageously made of one piece plastic. This is useful for a simplified manufacturing process.

According to the invention, the base body can also be designed to be height-adjustable. In this case, an extension piece, which is tubular, is arranged in the upper area of the base body. The extension piece advantageously engages in the upper area of the base body. It is also possible, however, for the tubular extension piece to overlap the upper area of the base body.

According to the invention, at least one socket seal is provided between the pipe and the base body. However, it is also possible to dispense with the socket seal, since plastic parts can usually be manufactured in such a way that the base body and the extension piece lie flat and tightly against one another.

According to the invention, the base body has an articulated outlet pipe section. This has the advantage that the connection between the base body and a connecting pipe lying in the ground can be easily established by placing the outlet pipe section over the articulated support in such a way that it points in the direction of the connecting pipe. The pipe sections can then be easily put together. No further aids are required for connecting the base body and a connecting pipe.

According to the invention, the base body is made of plastic. Construction materials for the base body are polymers, polycondensates or polyadducts.

The plastics used are preferably polyethylene (PE 32, PE 40, PE 63, PE 80 or PE 100), polypropylene (PP-H, PP-B, PP-R), polybutene (PB), plasticizer-free polyvinyl chloride (PVC-U, PVC-C, PVC-HI 1, PVC-HI 2, PVC-U-K), acrylonitrile-butadiene-styrene (ABS), acrylonitrile-styrene-acrylic ester (ASA) or styrene copolymers (linear polyesters, polycarbonates, unsaturated polyesters, epoxy resins, crosslinked polyesters, linear polyurethanes, crosslinked polyurethanes, polystyrenes).

The base body consisting of the above-mentioned construction materials advantageously contains reinforcing materials such as minerals, chalk, talcum, glass fibers, metallic fibers, plastic fibers or the like. This achieves higher material properties, so that the base body has greater stability and thus greater compressive strength.

The one-piece construction principle of the base body of the road gully according to the invention is achieved by suitable

Processing methods such as injection molding, rotational molding, bonding or welding.

According to the invention, the street drain has an odor trap. The odor trap is arranged on the drain pipe. The drain pipe, which is basically arranged to run diagonally downwards, makes an upward bend and another downward bend, such that the final direction of the drain pipe is at least approximately parallel to the direction of the drain pipe of the street drain. The draining water collects in the curved design of the drain pipe and remains there, so that odors that rise from the sewer system through the drain pipe cannot pass through the water collected in the bend.

Further details of the invention can be found in the subclaims.

The drawing shows an embodiment of the invention, namely:

Fig. 11 shows a bend of the outlet pipe with adjustable angle in section.

Fig. 1 shows a street drain (1) according to the invention with a support ring (2). The street drain (1) is arranged between a curb (3) and a street surface (4) in a drainage channel (5).

Fig. 2 shows the street drain (1) which is arranged in the sub-concrete (6, 7). In addition, the street drain (1) is fixed by the soil (8). The street drain (1) has a bucket (9) to collect mud or the like. A drain pipe (10) is also provided which is connected via an intermediate piece (11) to a drain pipe (12) lying in the soil (8).

The curb (3) is arranged in the sub-concrete (7). The support ring (2) is also arranged in the sub-concrete (6 and 7) in such a way that the support ring (2) encloses an upper area (13) of the street drain (1). The support ring (2) is completely supported by the sub-concrete (6, 7). A frame (14) made of cast iron for a cover is provided on the support ring (2). A grate (15) is provided above the street drain (1).

Because the support ring (2) is arranged in the sub-concrete (6, 7), the base body (16) of the road drain (1) no longer has a supporting function. For this reason, the base body (16) is made of plastic.

According to Fig. 2, a joint (22) is provided between the frame (14) and the high edge (3). This joint is filled with grout like the gutter (5).

The bucket (9) rests loosely or detachably attached to projections (23, 24) of the frame (14).

Fig. 3 shows the street drain (1) with the base body (16) and the drain pipe (10). Four pipe sections (32, 39, 40, 41) with sockets (33) are arranged in an arc on the drain pipe (10), each angled at 45°. The angles of the pipe sections (32, 39, 40, 41) are preferably 45°. However, it is also possible to make angles of 67.5° or 90°, for example. It is also possible to use fewer or more pipe sections instead of four pipe sections.

Due to the curved design of the pipes (32, 39, 40, 41) water remains with an upper water line (36) in

the pipe sections (32, 39, 40, 41). As a result, unpleasant odors from the sewer, which can rise through a drainpipe (34) into the street drain (1), cannot get past the water into the street drain (1), so that the street drain (1) remains odor-free or almost odor-free.

According to Fig. 4, the base body (16) of the street drain (1) is made up of several parts. The base body (16) has a wall (17) and a base (18).

According to Fig. 5, the base body (16) is made in one piece. This makes the manufacture of the base body even easier.

Fig. 6 shows the support ring (2), which consists of two parts (19, 20).

According to Fig. 7, the parts (19, 20) form an upper surface (21). The parts (19, 20) engage in a stepped manner, so that a support ring (2) is created with a uniform surface (21), in which the parts (19, 20) are firmly assigned to one another.

According to Fig. 8, the street drain (1) is designed to be height-adjustable. An extension pipe (25) is inserted into the base body (37) in the upper area (13) of the base body (37). In order to achieve a tight connection between the pipe (25) and the base body (37), an annular groove (38) is formed on the base body (37), which accommodates a socket seal (26).

For the purpose of a simplified representation, the drain pipe (10) of the bucket (9) and the other parts have been omitted from Fig. 8.

Fig. 9 shows the drain pipe (10) with an outlet pipe section (27). The outlet pipe section (27) has a collar (28). The drain pipe (10) has a double-walled design with walls (29, 30) in the area of the outlet pipe section (27). The collar (28) is arranged in a recess (31) which lies between the walls (29, 30). This allows the outlet pipe section (27) to move in the direction of arrow A and perpendicular to the plane of the drawing. The pipe section (27) can thus be rotated in the direction required for connection to a drain pipe (not shown).

Fig. 10 shows an outlet pipe section (42) which is arranged on an outlet pipe (44) of the base body (16) (not shown) by means of a ball joint (43).

The outlet pipe (44) can be pivoted to the central axis B of the outlet pipe section (42) by up to an angle α. Since it is a ball joint (43), pivoting directions with a component perpendicular to the drawing plane are also possible.

According to Fig. 11, a further embodiment is shown for the angular adjustability of an outlet pipe piece (45) to an outlet pipe (46) arranged in the base body (16) (not shown). The outlet pipe piece (45) and the outlet pipe (46) are detachably connected to one another by means of a clamping ring (47). A seal (48) is provided between the outlet pipe piece (45) and the outlet pipe (46).
