An Independent claim is also included for a process for manufacturing a run-off channel by bending sheet material.

Description

State of the art

The invention relates to a formed as a channel profile and drainage channel that can be made from a single sheet metal part, for laying in a floor with holding devices protruding laterally from the outside of the drainage channel walls and fixing devices, with one formed by the gutter walls Interior with a slope, the free ends of the gutter extending away from the interior are shoulder-shaped and are spaced apart in such a way that an opening forms, as well as a method for producing a Drainage channel.

Drainage channels of the above type are known in various designs. They are used as drainage devices in large kitchens, Dairies, butchers or wineries used to make appropriate Liquids, free-flowing or pasty materials as well as solids to be transported and disposed of via a drain system.

Such gutters have holding and fixing devices that project laterally away by means of which such channels are fixed on a floor, before a so-called screed (fine floor) is applied. alternative for this purpose, such channels are provided in recesses provided in floors involved.

Depending on the respective application, it is necessary between the holding and fixing device and the Foam the space between the channels to allow bacteria and fungi to form is avoided in this space. However, this is very high effort and associated high costs.

Such a floor channel is known for example from EP 0893 545 A. This drainage channel shown here has a polygonal cross section on, with the side walls initially moving from the opening Extend outwards, then vertically away from the opening extend and then subsequently at a defined angle to the Extend due to the drain profile. The holding and fixing devices are sheet metal parts at defined intervals along the length of the floor channel on the outside of the channel wall, which is directly from the Opening extends, arranged. This sheet-like formations of the Holding and fixing devices extend at a certain angle away from the gutter and each have one at their free ends Opening that in a corresponding fixing device, for example Bolts, which are then anchored in the ground, can be inserted.

The gutters of the above type are through several bending processes produced. They have the disadvantage that in particular below shoulder-like training, provided the drainage channels are not directly in are embedded in the screed, dirt accumulates. They are also Channels of the cross-sectional shapes or polygonal formations of the gutters very difficult to see, because they have undercuts. In addition, the radii are between the individual outer walls stretching away from the opening at such angles arranged to each other that dirt, especially in the angular ranges can accumulate.

The gradient in the gutters according to the prior art becomes like this creates that the vertical from the opening to the bottom Shorten side walls. This ensures that the reason for the the entire length of the gutter and create a slope can.

From US 4,787,773 is a gutter for laying in a floor known. The gutter points laterally from the outside of the gutter walls protruding holding and fixing devices and one in the interior slope formed on the gutter. The free ends of the gutter are school-like thanks to the corresponding drainage channel walls connected elements formed and spaced from each other, so that an opening is formed. The outer side walls extend from the First opening outwards and then form a semicircular cross section formed pot-like element by a deep-drawing process can be produced.

Object of the invention

Therefore, the object of the invention is a simplified training to create a gutter that after the disadvantages of the stand avoiding technology.

Advantages of the invention

The invention goes the way to create a gutter that means few advanced and other machining processes inexpensive can be produced. For this purpose, it is proposed according to the invention that the Drainage channel of the above type is designed such that the External walls from the opening first to the outside and then immediately extend inward to the bottom of the drainage channel. In addition, the Bending radii have a large radius, so that no dirt accumulates here are more possible.

In the invention, the way is left, the slope by shortening the To produce side walls. Rather, by setting up a different one Bending angle at the beginning of a sheet blank and at the end of the Sheet metal cut created the slope. Preferably in a last Bending step this slope is created by the two curved sides of the profile are bent to each other at the defined angle, so that the free ends of the profile are aligned accordingly.

Because of the cross-sectional geometry of the channel profile according to the invention two bending processes are saved. First, in a first bending step with a trapezoidal design of the sheet metal part along a Trapezoid outside curved. In a further step, the opposite trapezoidal side in the second step, in the third step along another line that runs between the axis of symmetry of the trapezoidal Training and a trapezoidal side is bent. In one penultimate step finds the identical one on the opposite side Bend with the identical bending radius instead. In a final step the bottom of the channel and thus the slope of the channel is created, by tracing the trapezoidal shape along the axis of symmetry is bent. As a result, the training according to the invention can be carried out in five steps of the channel profile.

Provided the free ends of the shoulder-shaped design of the channel profile to be skewed, there is an additional bend here instead of.

Another significant advantage of the invention is that due to the bending geometry creates an interior that is complete is visible so that it can be checked in a simple manner whether There is dirt in the gutter.

Another advantage of the invention is that the space, the between the shoulder-shaped free ends of the channel profile and the fixing and holding device is completely closed, by the fixing and holding device is attached in such a way that it on the one hand is arranged directly on the outer wall, which is different from the Opening extends away and on the other hand arranged on the outer wall is that the cavity is closed like a lid.

The fixing and holding device advantageously extends over the entire length of the gutter, so no dirt or the like can get into the cavity.

Preferably there is a drainage channel and the holding and fixing device made of stainless steel. Depending on the application, other materials are also available conceivable.

In order to achieve a very smooth surface in particular and advantageously To create interior of the gutter, and to prevent any Dirt particles can deposit here is also provided Electropolish surface.

Further advantageous configurations are given in the descriptions below as well as from the drawings.

Description of an embodiment

In Fig. 1 the gutter 1 is shown in perspective.

It comprises drainage channel walls 2, which are arranged almost in a diamond pattern with respect to one another are, the drainage channel 1 opening 3 on one side has the shoulder-like extending laterally away from the opening 3 Training 4 includes.

Furthermore, an interior space 5 is formed by the drainage channel walls 2.

On the shoulder-like formations 4 preferably one in the Drawing not shown grid are placed, so here only accordingly large parts can fall into the gutter 1. This grating, not shown in the drawing, can not be used in more detail shown holding devices on the shoulder-like training 4 be attached. Furthermore, a holding and fixing device 8 is provided.

In Fig. 2 the formation of the channel profile of the gutter 1 is clear to recognize. The free ends 6 of the gutter 1 also indicate an end 7 at its ends. In addition are under the bends 7 holding and fixing elements 8 arranged, these being almost U-shaped are formed and one end of the U-shaped holding and fixing element 8 strikes immediately at the end of the offset 7, so that between the free end 6 of the offset 7 and the holding and fixing element 8 a cavity 9 which is closed per se is formed. Since the Holding and fixing device 8 preferably over the entire length of the Drainage channel 1 extends, the cavity 9 is formed over the entire Length of the drainage channel 1 closed, so that foaming this Partly can be omitted.

The other free end of the U-shaped holding and fixing element 8 is provided for one not in the drawing of FIG. 2 in more detail shown bolt element 10, by means of which the gutter 1 can be attached to a floor, not shown.

The drainage channel 1 shown in FIG. 2 is about an axis of symmetry 11 constructed symmetrically. A first wall part T1 extends from the opening 3 at an angle W1 away from the axis of symmetry. it a further wall part T2 is then arranged at an angle W2, which extends to the bottom 12 of the gutter 1.

A slope 13 is arranged inside the interior 5. This slope 13, which is shown in section in FIG. 3, is achieved in that a trapezoidal sheet metal part 15 is used to produce the gutter 1 which is shown in Fig. 4. In a first bending step along a line A becomes the shoulder-shaped formation Part T0 bent and created. Then in a further step symmetrical to the axis of symmetry 11 on the opposite side further shoulder-shaped training 4 or part T0 created.

In a further bending process is then along a line C that is parallel is formed to line A, which extends away from the opening 3 Part T1 created. The next step is the symmetrical one Page created along a line D.

In a final machining process, a line E is then bent, which is also the axis of symmetry 11 and the base 12 in the channel profile equivalent. In order to ensure a symmetrical arrangement of the gutter 1, it is necessary to adjust the bending angle at one end (trapezoidal side S3) towards the other end (trapezoidal side S4).

The holding and fixing devices are preferably by means of Welding spots attached to the outside of the outer walls 2. The Interior, which is formed by the corresponding walls, preferably faces a very smooth surface. To such a smooth surface to achieve is more advantageous when using stainless steel sheets Way provided to electropolish them.

Furthermore, the corresponding bending radii R have large radii it is avoided that dirt or the like in these areas can set as well as bacteria and fungi.
