Title: Gutter part for a drainage gutter system

The invention relates to a gutter part for a drainage gutter system on streets, squares, etc. Such drainage gutter systems generally consist of several gutter pieces made of concrete or other materials arranged in a row, which have a gutter recess that is open at the top and are covered with a walkable cover grid or a cover plate with openings.

To carry out changes in direction, curved gutter parts have already become known, which are inserted into the drainage gutter system according to the desired gutter course.

Such arched gutter parts are relatively expensive to manufacture. In addition, once an arched part has been formed, the curvature is fixed and

· i

&igr; t ·

For other curves, additional arched channel parts must be manufactured, which also require new shapes.

The present invention is based on the object of creating a gutter part for a drainage gutter system on streets, squares, etc., with which any change in direction of the drainage gutter or an arcuate or circular design of the drainage gutter system can be carried out in a simple manner.

To solve the problem, a gutter part of the type mentioned at the beginning is proposed, which is characterized in that the gutter part has a trapezoidal plan and cross-section perpendicular to the course of the gutter recess or the flow direction of the water with parallel side edges and front edges running at an angle to each other.

The gutter part according to the invention has the significant advantage that any desired change in direction in the drainage gutter system can be created by arbitrarily arranging the gutter parts according to the invention. Furthermore, larger curved courses and circular drainage gutters can also be produced in a simple manner using the gutter part according to the invention. If larger circular radii are required, the gutter parts according to the invention can be laid alternately with straight, rectangular gutter parts.

A further advantage is that the gutter part can be manufactured very easily by using existing moulds, whereby only partition walls have to be built into the mould in accordance with the trapezoidal plan or cross-section. |

Gortiäß of a special embodiment is for a

Gutter part according to the invention, the ratio of the longer side edge to the shorter side edge is approx. 1 : 1.2

\ to 1 : 1.3. This means that the front edges of the

inner part at an angle of approximately 15° to each other

get lost.

The channel part according to the invention can be attached to the upper

j! Side edges have correspondingly long angle attachments

S Sen, in which a trapezoidal grid cover or

ff a concrete cover with drainage holes is placed

&ngr;- and can be fixed using screws, for example

&lgr; can.

The drawings are intended to illustrate the example of a preferred \ th embodiment, the gutter part according to the invention

and the drainage gutter systems that can be manufactured with it are explained in more detail.

In the drawings, ■ Fig. 1 shows a plan view, and

Fig. 2 shows a section of a particular embodiment of the gutter part according to the invention.

Figures 3 to 6 show plan views of sections of a drainage channel system with the channel part according to the invention.

Fig. 7 shows the design of a circular gutter system in plan view, which can be arranged, for example, around a well.

As can be seen from the figures in the drawings,

the channel part consists of a molded body 1 made of concrete with an inner, U-shaped channel recess 2. Perpendicular to the flow direction, according to arrow 3, the channel part has a trapezoidal outline or a trapezoidal cross-section (Fig. 1) with two parallel side edges 4, 5 and two front edges 6, 7 running at an angle to each other. The ratio of the long side edge 4 to the short side edge 5 is approx.

I : 1.2 to 1 : 1.3. In this way, the two front edges 6, 7 run at an angle <3C of 15° to each other.

A long angle piece 8 and a short angle piece 9 are attached to the upper surfaces of the side edges 4, 5. A suitably shaped cover, for example a cover grate 10 (Fig. 3) or a concrete slab with openings, can be fitted into these two angle pieces 8, 9.

II (Fig. 4).

Fig. 3 shows a top view of how the drainage direction of a straight gutter section 12 can be changed by 30° by means of two gutter parts according to the invention.

In Fig. 4 a similar arrangement is shown in which a change in the flow direction of 45° is produced by means of three channel parts according to the invention.

Fig. 5 shows a further possible embodiment in which a change in flow direction of 60° can be produced by four channel parts according to the invention.

Fig. 6 shows the course of a drainage channel system in which the drainage direction is initially at an angle of 45° in one direction and then in

ft · t f &igr;&igr; t «

&bull; · t · ■ t * · ■

an angle of 45° in the opposite direction. All that is needed is three plus three gutter parts, which are lined up with their short side edges first in one direction and then in another direction. This means that any drainage gutter system can be created using any combination.

A particular example is shown in Fig. 7. Here, with the aid of twenty-four gutter parts according to the invention, a circular drainage gutter system is created, which is arranged, for example, around a well 13 shown in principle.

The gutter part according to the invention can be made of concrete or other materials.
