Shaped stone with internal drainage channel

The innovation concerns a shaped block with an inner drainage channel and a large number of one behind the other with spacing between them arranged breakthroughs between the stone surface and the drainage channel, which expand downwards and approximate have a rectangular cross-section.

There is already such a shaped block made of concrete o. The like. Known (DE-OS 22 42 736), which has a rectangular elongated Owns shape. The molded stone material directly delimits the longitudinal channel and the inlet openings. This well-known shaped stone is used as a so-called drainage block for the drainage of e.g. roadside shoulders, squares etc. and should be used against others The designs used have increased compressive strength in the transverse direction exhibit.

For this purpose, the openings are designed and arranged so that the longer sides of their rectangular cross-sections run across the drainage block. However, the disadvantage of this known block is its comparative nature complex production, which requires a large number of operations, especially for forming the inlet openings. On the other hand, the upper edges of the inlet openings can become higher, sometimes more jerky, under the effect Loads crumble and are pressed into the breakthroughs - despite their shape expanding downwards, so that there is constipation. In addition, there is a risk of water between the bumps from one another laid drainage blocks seeps through, which can lead to warping and frost breakouts in winter.

From GB-PS 1 399 113 another shaped stone for drainage purposes is known, which is also a rectangular one Cross-section and an inner drainage channel possessed by means of a channel extending over almost the entire length of the stone Slot is connected to the stone surface. For connecting two stones laid one behind the other separate socket pieces are used, which are inserted into correspondingly widened end sections of the inner longitudinal channel will. With this known stone there is also the risk of breaking off or crumbling of the slot edges, if the stone is laid e.g. on highly loaded loading areas.

The object of the innovation is to provide a molded block of the initially introduced that eliminates the disadvantages of known designs to create mentioned type, which can be produced much easier and with the breakouts in the edge area the breakthroughs are avoided.

According to the invention, this object is achieved in that the drainage channel is fixed by one in the molded stone material embedded plastic pipe is formed with round openings in the apex area, in which the molded stone material tightly enclosed inlet spouts made of plastic are attached, their flush with the stone surface Openings form the inlet openings of the breakthroughs.

The use of inlet spouts and a plastic pipe as quasi linings of the drainage channel and the Breakthroughs lead to a much simpler production because the pipe with the previously attached to it Inlet spouts themselves form the mold core for shaping the stones. Due to the flush finish of the grommet openings along with the stone surface, there are also breaks in the edge area and the resulting blockages of the breakthroughs safely avoided.

According to an advantageous further development, the grommets are held securely and leak-tight in the plastic pipe the innovation through a threaded attachment at the lower wide end of the inlet spouts and a sealing one Reached annular flange, the lower surface of which is adapted to the arch shape of the plastic pipe and screwed in Condition rests evenly on the edge of the pipe openings. For better anchoring of the plastic sleeves in the surrounding concrete, lateral tabs are molded on.

A leak-tight laying of the Pormsteine to be continuous Drain pipes is achieved according to another expedient development in that in each case one end part of the

Plastic pipe as part of a push-in socket connection is formed, with one of these parts having an enlarged cross-section and the other end part protrudes from the abutment surface of the stone by a corresponding amount. A precise fixation of the position of the individual shaped stones is achieved by at least one bolt in the bottom of each stone that protrudes beyond its abutment surface and its hook-shaped end engages in a corresponding recess in the bottom of the next stone.

The following is an example of the innovation described in detail with reference to the drawing. Show it:

1 shows a shaped block in cross section;

FIG. 2 shows the shaped block according to FIG. 1 in a perspective illustration; FIG.

Fig. 3 two interconnected shaped bricks in longitudinal section.

The shaped block shown has a substantially rectangular cross section and is preferably made of Concrete 1. In the lower part of the shaped stone extends a longitudinal channel 2, which is firmly enclosed by the concrete Plastic tube 3 is formed. In the apex of this plastic pipe 3 round openings 4 are predetermined Intermediate spacings arranged one behind the other, in which inlet spouts 5 sit made of plastic. These plastic grommets have a rectangular cross-section which widens from the inlet opening 6 to the outlet pipe 2, 3. The long sides of the rectangular grommet cross-sections extend parallel and symmetrically to the long sides of the Formsteins. The surfaces of the shaped stones have an arched

shaped channel 7, in the deepest section of which the nozzles 5 open out with their openings 6.

To firmly embed the grommets in the concrete material 1 are in their middle area on each long side a tab 8 is integrally formed, in which recesses can be arranged to achieve a toothing engagement. The lower part of each grommet contains a threaded attachment 9 with which the grommet can be inserted into the opening 4 of the plastic pipe 3 is screwed in, as well as an annular flange 10, which is located with its lower arcuate annular surface on the pipe jacket supported over a large area and together with a tensioning effect of the inside of the pipe when the grommet is screwed in Threaded extension 9 causes a liquid-tight seal.

Reinforcements 11 are anchored in the concrete material 1 protrude over the side and bottom surfaces in the form of splayed fork ends and when laying the stone e.g. as an element of closed asphalt or concrete pavements, a high-strength connection to the adjacent materials produce.

As can be seen from FIGS. 2 and 3, an end section 12 of the pipe 3 is expanded to form an outer sleeve, whereas the other pipe end piece 13 protrudes by a predetermined amount over the abutment surface 14 of the shaped block. According to FIG. 3, this protruding end piece 13 engages in the enlarged socket part 12 of an adjoining shaped block a, whereby due to the sealing properties of the plastic materials (PVC) a self-sealing without additional measures are achieved. For the secure fixation of two adjoining shaped stones as well as serve to secure the socket connection 12, 13 in FIG. 3

their end hooks 16, 17 in corresponding recesses 18 in the bottom part of the molded blocks on the side of the plastic pipe 3 are arranged. These bars can, however, also be cast into the molded block on one side and correspond to one de length protrude freely over the abutment surface 14 of this stone.

The innovation is not limited to the embodiment shown. For example, instead of the fork-shaped reinforcements 11 no or differently designed Reinforcements are provided. Plastic strips, for example, can be used to seal the gaps between adjacent joints 20 can be printed in this column. Also filling or greasing these gaps with mortar or cement is possible. Appropriately, the spouts have a greater length before the stone is formed, with their topmost, if necessary, closed end cap is cut off after the stone has been shaped, in order to ensure that it is exactly flush Arrangement of the nozzle openings 6 of the surface of the shaped stone to obtain.
