Description

The invention relates to a flooring element for formation a gutter, with a top on which a gutter section is formed, a bottom, two on opposite Pages arranged in the longitudinal direction of the Channel section extending long sides, a first End face, on which a first cross-section of the mouth of the channel section lies, and one opposite the first end face second face, on the second cross section of the mouth of the channel section, with the End faces in each case at least one in the longitudinal direction of the channel section protruding engagement section and at least a recessed in the longitudinal direction of the channel section Receiving section is formed, each engagement section with one receiving section and each receiving section with an engaging portion of an adjacent one Flooring element can be brought into engagement, wherein one formed between the underside and the first end face Edge has a course that is essentially congruent with a course of one between the bottom and the second end face formed edge and the edges are not parallel to each other.

For the formation of a drain or floor gutter, for example on roadsides or paved paths or Squares are usually prefabricated gutter stones used, each forming a channel section and in be put together in a row, whereby the groove is formed is. To ensure mutual security of neighboring positions To reach gutter stones, it is for example from DE 85 09 982 U1 and DE 295 14 127 U1 known, on the one respective mouth cross-section of the channel section end faces each have at least one in the longitudinal direction of the groove portion protruding engagement portion to form and to provide recesses in the engage an engaging portion of an adjacent gutter stone can. This way, between neighboring Gutter stones a mutual engagement in the form of a toothing reached, the relative displacement of the gutter stones prevented transversely to the longitudinal direction of the channel.

In the gutter stone both according to DE 85 09 982 U1 also according to DE 295 14 127 U1 have the end faces of the gutter stone is a complementary shape and thus congruent Courses of their between the bottom and of the respective end face formed. In this way can be the first face of a first gutter stone with a close fit to the second face of an identical create the shaped adjacent second gutter stone. and engage with it. The shape of the end faces is symmetrical to a central longitudinal axis of the gutter stone and the end faces run in a basic version of the gutter stone essentially parallel to each other and perpendicular to the longitudinal direction of the Gutter section. This way you can use the gutter stone according to the basic version, however, only linear Reach channels. In many cases, next to one straight course of a gutter also training a curve desired. For this purpose, according to DE 85 09 982 U1 and DE 295 14 127 U1 special curve stones provided, which differs from the basic version of the gutter stone differ in that the end faces are not parallel run to each other, but one between themselves Include an acute angle. In this way the mouth cross section of the channel section on the first End face relative to the mouth cross section of the channel section angularly offset on the opposite second face or twisted, whereby the course of the gutter undergoes a redirection.

A disadvantage of those from DE 85 09 982 U1 and DE 295 14 127 U1 known flooring elements, however, is that for the formation of a straight channel section and for the Formation of a curved channel section different Gutter blocks must be used, which is not only in terms of manufacturing and warehousing, but also is unfavorable when setting up the gutter.

The invention is based on the object; a flooring element of the type mentioned, with which both a rectilinear as well as a curved channel course can be formed is.

This object is achieved in a flooring element of the type mentioned in that the edge K _1.1 formed between the underside and the first end face and the edge K _2.1 formed between the underside and the second end side each have a center point P ₁ or P ₂ point symmetrical course. The point-symmetrical course of the edges K _1.1 and K _{2.1 of} the floor covering element according to the invention makes it possible to place a floor covering element in one of two possible orientations on an already laid floor covering element. In the floor covering element according to the invention, the edges K _1.1 and K _{2.1 have} an essentially congruent course, but are not arranged parallel to one another and form a preferably acute angle α between them. This corresponds to the structure of the curve stones known from the prior art. If the floor covering elements according to the invention are placed against one another in the same orientation, the first end face of one floor covering element engaging with the second end face of the adjacent floor covering element, the course of the floor channel is deflected by the angle α for each floor covering element.

Alternatively, however, it is also possible to apply a floor covering element in an orientation rotated by 180 ° about a vertical central axis, so that the second end face of one gutter block then engages with the second end face of the adjacent gutter block. With this orientation, the deflections cancel each other out by the angle α in the two gutter stones, so that the gutter has a substantially straight profile. In this way, the user can optionally form straight or curved sections of the floor channel with a single type of flooring element. This advantage is achieved according to the invention in that each end face of the gutter block according to the invention can optionally be brought into engagement with the first or the second end face of an adjacent gutter block, which is ensured by the point-symmetrical course of the edges K _1.1 and K _2.1 .

In a preferred embodiment of the invention it is provided that the edges K _1.1 and K _2.1 each have a polygonal course, which can preferably be a zigzag course and in particular an S or Z-shaped course. Due to the zigzag shape of the edges K _1.1 and K _{2.1 there} is a good mutual engagement of adjacent flooring elements and in particular a large mutual contact with a lateral load acting transversely to the longitudinal direction, so that high point stresses are avoided and a high level of fracture resistance is ensured is.

Both the end faces and the long sides of the floor covering element preferably comprise vertical wall sections which are oriented essentially perpendicular to the underside. In this way, the floor covering element has a constant outline contour over its entire height and an edge K _1.2 formed between the upper side and the first end face lies in the vertical projection of the edge K _1.1 formed between the underside and the first end face. Accordingly, an edge K _2.2 formed between the upper side and the second end face lies in the vertical projection of the edge K _2.1 formed between the underside and the second end face.

In one possible embodiment of the invention, that on each face there is a single one, about the entire height-extending engagement section and a corresponding a recess forming a receiving section is trained. To ensure safe intervention from neighboring To ensure flooring elements, the engagement section should by a sufficient amount in the longitudinal direction of the channel section protrude from the front. It has proven to be advantageous if the extent to which the engaging portion protrudes from the respective end face, about 0.1 to 0.4 times and especially 0.2 times that measured transversely to the longitudinal direction of the channel section Width of the flooring element is.

The mutual angular offset between the edges K _1.1 and K _2.1 takes place around a point D lying outside the floor covering element. The two edges enclose an angle α between them which is in the range from 2 ° to 10 ° and in particular in the range from 5 ° to 7 ° lies. The point D should have a distance of approximately 5 to 25 times and in particular 8 to 12 times the width of the floor covering element measured transversely to the longitudinal direction of the channel section from the center thereof.

In practice, the problem often occurs with the gutter form a curve over an angular range of 90 °. For this reason, the offset angle α should be between the two end faces of the flooring element so chosen be: n x α = 90 °, where n is a natural whole Number is.

If the flooring elements form a substantially rectilinear gutter arranged in an alternating arrangement the outer surface of the gutter should be straight and run in one plane. This will be in continuing education the invention achieved in that the long sides run straight and parallel to each other.

The course of the channel section within the flooring element can either be straight or slightly curved his. To especially when forming a curved Gutter course an excessive deflection of the Preventing flow is in an embodiment of the invention provided that a longitudinal center line of the gutter section runs curved and especially on a circular arc around a center lying outside the flooring element lies around which the end faces are relative to each other are angularly offset. It can be provided that the

Distance of the center point from the longitudinal center line greater than or equal to the distance of point D from the Longitudinal centerline is. The distance from the center of the longitudinal center line should be larger by a factor f than the distance of point D from the longitudinal center line be, the factor f in the range of 1.0 to 5.0 and is in particular in the range from 2.0 to 3.0. The point D and the center are arranged so that the point D lies between the center and the flooring element.

In a preferred embodiment, the channel section has of the flooring element relative to its longitudinal center line symmetrical cross section that is either continuous be curved concave or polygonal can. The lowest point of the flow cross-section of the channel section is called the bottom point. The bottom points all successive cross sections of the channel section thus result in a bottom line that is preferred corresponds to the longitudinal center line of the channel section.

To give the gutter a look as if it were made from one Variety of single cuboid or polygonal or assembled in otherwise shaped blocks is, it is preferably provided that the surface of the Channel section formed with a dummy structure is. The false joints, the groove-like depressions on the top formed, also hinder the flow of water and reduce the flow rate.

The flooring element is preferably made of concrete, however, appropriate flooring elements can be used also manufacture from natural stone or artificial stone.

a flooring element composed of two stone parts.

A flooring element 10 shown in FIGS. 1 to 3 in the form of a monolithic concrete part has a flat, substantially horizontal bottom 16 and a top 11, on which a channel section 20 is formed, the runs in the longitudinal direction L and on a first end face 12 a first cross section of the muzzle and on one of the first end face 12 opposite second end face 13 has a second mouth cross-section. The gutter section 20 is arranged from two on opposite sides, extending in the longitudinal direction L of the channel section 20 Long sides 14, 15 limited. The first face 12, the second end face 13 and the long sides 14 and 15 each have vertical wall sections that are essentially run perpendicular to the underside 16.

3 shows, the channel section 20 has a symmetrical, polygonal concave cross section with an in Longitudinal direction L running longitudinal center line S which the Bottom line of channel section 20, i.e. the the low points of all the channel cross-sections lying one behind the other Line corresponds.

The long sides 14 and 15 run parallel to one another and each comprise a vertical wall surface. The first end face 12 and the second end face 13 have a polygon-like course composed of a plurality of wall sections. As can be seen from FIG. 2, an edge K _1.1 formed between the underside 16 and the first end face 13 has a course which is essentially congruent with the course of an edge K _2.1 formed between the underside 16 and the second end face 13, wherein however, the edges K _1.1 and K _2.1 do not run parallel to one another, but are angularly offset by an angle α about a point D outside the floor covering element 10 (see FIG. 4). The point D has a distance from the center of the floor covering element of approximately 8 to 12 times the width of the floor covering element measured transversely to the longitudinal direction L of the channel section and the angle α is preferably in the range from 3 ° to 7 ° and in particular in Range from 5 ° to 7 °, it being pointed out that the dimensions and angles shown in the figures are shown enlarged for the purpose of illustration.

Both the edge K _1.1 and the edge K _{2.1 have} an S-shaped course which is also at their center P ₁ or P ₂ . The center point P ₁ lies below the longitudinal center line S of the channel section 20. The same applies to the center point P _{2 of} the edge K _2.1 on the second end face 13.

5, the first end face 12 thus related to an imaginary connecting line T between the front ends of the long sides 14 and 15 one protruding in the longitudinal direction L of the channel section, in supervision triangular engagement portion 12a one side of the longitudinal center line S of the gutter section and a complementary receiving portion 12b on the other side of the longitudinal center line S. The in Longitudinal direction L of the channel section measured maximum Extension h of the engagement section 12a should at least have 0.1 times the width of the flooring element and points in the embodiment shown in FIG. 5 about 0.2 times the width of the flooring element on.

A corresponding engagement section 13a and a corresponding receiving section 13b are formed on the second end face 13 opposite the first end face 12, these sections, however, due to the congruent course of the edges K _1.1 and K _2.1 compared to the arrangement on the first end face 12 in an exchanged manner Arranged in this way, that is, on the side of the longitudinal center line S of the channel section 15, on which the first end face 12 has the engagement section 12a, a complementary receiving section 13b is formed on the second end face 13, and on that side of the longitudinal center line S of the channel section 20, on which the first end face 12 has the receiving section 12b, the complementary engagement section 13a is formed on the second end face 13.

As shown in FIGS. 2 and 4, the longitudinal center line runs S of the channel section 20 curved around on a circular arc a center, not shown, of the flooring element 10 is further away than point D, where the point D between the center point and the flooring element lies. The in the longitudinal direction L of the channel section extending longitudinal sides 14 and 15, however, run in a straight line and parallel to each other.

As can be seen in FIG. 2, the outer top point P _{E1 of} the engaging section 12a of the first end face 12 is a small amount relative to the upper, most retracted point P _{A2 of} the receiving section 13b of the second end face 13 with respect to the longitudinal direction L of the channel section 20 laterally offset. A corresponding lateral offset also exists between the upper, most retracted point P _{A1 of} the receiving section 12b of the first end face 12 relative to the upper outer tip point P _{E2 of} the engaging section 13a of the second end face 13. This offset is due to the angular offset between the edges K _1.1 and K _{2.1 due} to the angle α. As can also be seen in FIG. 3 ', there is also a slight height offset between the points mentioned in order to avoid excessive cracks in the surface of the channel when a channel is built up.

Fig. 6 shows the construction of a gutter from several flooring elements 10, which are placed in the same orientation are, i.e. a first floor covering element 10 * is present its second face with the first face one adjacent flooring element 10 ** in plant, the Engagement section 12a ** of the first end face of the applied Flooring element 10 ** with a tight fit in the Receiving section 13b * of the second end face of the first Flooring element 10 * engages. Accordingly, the Engagement portion 13a * of the second end face of the first Flooring element 10 * with a tight fit in the receiving section 12b ** the first end face of the created flooring element 10 ** a. The result is a curved one Gutter, because each flooring element created around the Angle α compared to the previous flooring element is twisted.

Alternatively, however, one is also possible to form a straight channel as shown in FIG. 7 is. For this purpose, the flooring elements are alternating Alignment aligned. To a first one Floor covering element 10 * becomes a second floor covering element 10 ** created so that the second end face 13 * of the first Floor covering element 10 * with the second end face 13 ** of applied flooring element 10 ** engages. by virtue of this arrangement becomes the angular offset by the angle α, between the first face and the second Front face of the first flooring element 10 * occurs, by the corresponding angular misalignment α between the second End face and the first end face of the created flooring element 10 ** canceled so that one in essentially straight gutter can be built, the individual channel sections 20 due to the minor Curvature of their longitudinal center line S a slight serpentine shape form, as is apparent from Fig. 7. Since the Long sides 14, 15 of the flooring element, however, in a straight line and run parallel to one another, the groove 15 has a flat end surface on the outside.

The floor covering element shown in supervision in FIG. 8 differs from the aforementioned flooring element essentially in that on the top all over a dummy joint structure 17 is formed that intersects Grooves, which creates the visual impression, as if the flooring element made of a variety of individual stones be composed. All other essentials Features of the flooring element according to FIG. 8 correspond 1 to 5.

The floor covering element according to FIG. 9 differs from the floor covering element according to FIG. 8 on the one hand in that the false joint structure is not applied in a substantially square or diamond-shaped grid, but in a large rectangular grid with square sections in between. In addition, the end face each has two engagement sections 12a projecting in the longitudinal direction of the channel section and two receiving sections 12b and 13b complementary thereto. The edges K _1.1 and K _2.2 thus have a course in the form of a double Z or a double S.

Fig. 10 shows a modification of the flooring element according to 1, which differs from this only in that that the flooring element 10 from two individual stone parts 10 'and 10' '. For this purpose, the flooring element 10 in the longitudinal direction in the two stone parts 10 'and 10' 'split, thus forming the flooring element 10 are assembled laterally. As Fig. Figure 10 shows the interface between the two Stone parts 10 'and 10' 'in the longitudinal direction L of the flooring element and has a zigzag or S or Z-shaped course, so that a good mutual engagement of the two stone parts is reached. The dividing surface runs in the area of the longitudinal center line S of the channel section serpentine around it, so that a Part of the longitudinal center line S on the one stone part 10 ' and the remaining part of the longitudinal center line S on the other stone part 10 ''. After the two stone parts 10 'and 10' 'laterally assembled to the floor covering element 10 are in the context of the Fig. 1 to 5 explained features and advantages on the this point should not be discussed again.
