A gutter section (16) is at the upper surface with an identical entry (Q1A) and exit (Q1E) cross section. The under side of the block also has a gutter (17), with its entry (Q2A) and/or exit (Q2E) cross section identical with the dimensions of the upper gutter.

Description

The invention relates to a flooring element for formation a gutter according to the preamble of claim 1, with a top, a bottom and several side surfaces, with a first channel section on the top with an initial cross section and with it identical end cross section is formed.

For example, for the formation of a drain or floor channel on the side of the road or on paved paths or Places are from DE 85 33 167 U1 special flooring elements and in particular flooring slabs made of concrete, natural or artificial stone known, the top of a groove-like have formed channel section, which on a side edge with an initial cross section and at another Side edge with an identical end cross section opens. Multiple flooring tiles can be used to form a floor channel with their gutter sections put together due to the identity of the initial and final cross-sections a smooth transition between the individual Channel sections is guaranteed. On the bottom is the floor covering plate shown in DE 85 33 167 U1 formed a recess, the use of which in the DE 85 33 167 U1 is not specified.

Although with the flooring tiles according to DE 85 33 167 U1 easily form a straight floor channel lets are for the design of curved channel sections or from side inlets and outlets or of branches or crossings of the gutter special Constructions necessary, usually on the construction site must be manufactured in in-situ concrete, is time consuming and therefore costly.

The invention has for its object a flooring element to create the kind with which the training a non-rectilinear gutter is.

Proceeding from the preamble of claim 1, this task is carried out in the case of a floor covering element Art solved according to the invention in that on the bottom a second channel section with an initial cross section and an end cross section is formed, wherein the initial cross-section and / or the final cross-section of the second channel section equal to the start and the end cross section of the first channel section is being, the course of the first channel section, i.e. the geometric shape of the channel section especially under supervision, different from that The course of the second channel section is. On the Construction site, the user of the flooring element can decide whether he does this with the first channel section or the installs the second channel section in the floor channel to be formed. In this way there are a variety of design options given that the formation of non-linear, for example curved or branching gutters facilitated.

Preferably, one of the channel sections is and in particular the upper first channel section is straight with an im essentially constant cross section. Such a designed first channel section can then in a conventional Way to make a straight, continuous Gutter can be used. The underside second Channel section is designed as a special shape and can for example with a substantially constant cross section run sinusoidally or to form a Redirection of the course of the floor channel continuously curved in one direction his. Within the second channel section, too a cross-sectional constriction serving as a throttle or also a barrier serving as a retaining element or sieve his.

The first initial cross-section and the first final cross-section of the first Channel sections are identical in a known manner. The the second initial cross section preferably also has an identical shape and the second end cross section of the second channel section, so that always a continuous, stepless Transition between the channel sections laid together Flooring elements are given regardless of which one of the two gutter sections used to form the bottom gutter becomes.

In a special embodiment of the second channel section can be provided that this is a branch point with at least one side arm. The side arm serves to form an inlet or outlet of the floor channel or also, two gutters to a common gutter merge.

The side arm opens on a side edge of the flooring element with a final cross section that is preferably the same the first start and the first end cross section of the first channel section is. Because in this case all start and end cross sections are identical, the training is again of continuous, smooth transitions between the gutter sections of adjacent flooring elements ensured. It is preferably provided that the Sidearm extends at an angle ranging from 45 ° to 90 ° and in particular perpendicular to the second channel section extends, which in this case be rectilinear can.

In a development of the invention it can be provided that in the second channel section in the area of the junction a flow guide device is arranged in which it is a hydraulic obstacle, for example can, which is integrally formed on the flooring element is. On the one hand, the hydraulic obstacle can serve to divide the flow in the desired manner or Merge partial flows and excessive if necessary To prevent flow turbulence. This is particularly so possible if the hydraulic obstacle on the side of the second channel section facing away from the side arm is arranged. In addition, the hydraulic obstacle serve to be carried in the water flow Foreign objects, for example an empty beverage can or to hold the bottle back, which is helpful if the hydraulic Obstacle arranged in the middle of the second channel section is.

The floor covering element is preferably made as a finished part Concrete, but it can also be made from natural stone, Artificial stone or plastic. In particular it should be plate-shaped with an essentially rectangular Floor plan, alternative floor plans, for example, are a trapezoidal floor plan also possible.

possible cross-sectional shapes of the channel sections.

A floor covering element 10 shown in FIGS. 1 and 2 for forming a floor channel has an essentially cuboid shape with a rectangular outline and has an upper side 11, a lower side 12 and four vertical side surfaces, of which only three side surfaces 13, 14, 15 are visible. The floor covering element 10 is a prefabricated prefabricated concrete part and has on its upper side a first channel section 16 which extends in a straight line from the front end face 13 to the opposite rear end face 15 and has a cross section which is constant over its entire length. The first channel section 16 has a first initial cross section Q _1A on the front end face 13 and opens out on the opposite rear end face 15 with an identical first end cross section Q _1E .

The cross section of the first channel section 16 is shown in FIG 15A explained in detail. As shown there takes the cross section of the first channel section 16 substantially the middle half of the width of the flooring element 10 a. Those remaining next to the first channel section 16 Areas 11a of the top 11 of the flooring element 10 extend substantially horizontally. On the inside close steeply, i.e. to the Middle of the flooring element 10 falling flanks F, which in slightly inclined downwards towards the middle of the 1st channel section 16 Pass over floor sections B. The cross section of the first Channel section 16 is symmetrical to the vertical, in Longitudinal center plane of the flooring element, so that the lowest point of the cross section in the Middle level lies.

15B shows a modification of the cross section according to FIG. 15A and differs from it only in that the areas running next to the first channel section 16 11a of the top 11 of the flooring element 10 itself not horizontally, but to the first channel section 16 Extend slightly inclined, causing the flooring element 10 rainwater strikes the first Channel section 16 is supplied.

Another alternative cross-sectional design is shown in FIG. 15C, the actual first channel section 16 having a V-shaped cross section with sloping bottom sections B. and which lie laterally next to the first channel section 16 Areas 11a of the top 11 of the flooring element are inclined downward towards the first channel section 16 and go directly into the bottom sections B.

As shown in FIG. 2 in particular, the floor covering element 10 has a second channel section 17 on the underside 12, which comprises a straight main arm 17a and a side arm 19 which branches off from the main arm 17a at a branching point 18. The main arm 17a extends in a straight line between the front end face 13 and the opposite rear end face 15 and has a constant cross section which corresponds to the cross section of the first channel section 16 on the top side 11 of the floor covering element 10. In this way, the second gutter section 17 is equipped with a second initial cross section Q _2A and a second end cross section Q _1E , which are identical to the first initial cross section Q _1A and the second end cross section Q _{1E of} the first gutter section 16.
