Description

The invention relates to a composite paving stone made of concrete with a circumscribing two squares Baseline and can be converted into one another at the four in pairs by shifting in parallel Steinsciten arranged straight side sections, the right and otherwise blunt at the stone corners Include angles with each other, protruding over the baseline and behind the Baseline receding indentations form, two consecutive times on the long stone sides Show the tooth profile of the short stone sides and preferably on the short stone sides are the same length.

Composite paving stones of this known type show both on their long stone sides and on its short stone sides have a toothing of indentations and protrusions. Building with a two squares circumscribing the baseline serves to indicate the possibility of laying in different Open stone groups in which the stones are offset against one another by part of their length can be arranged next to each other so that one stone is the connection joint of two neighboring stones bridged. With an ideal composite paving stone, each such bridge has a staple-like effect Composite effect on the two neighboring stones.

In the case of a known composite paving stone of the type mentioned (German utility model 1 858 336), the apexes of the projections and indentations run a total of about two thirds the length of their stone side parallel to the baseline and are through oblique to the baseline Side sections connected, which have to absorb the entire load when combined. the short stone sides can be converted into one another by means of a right-angled parallel shift, while an oblique parallel displacement is required to transfer the long stone sides, which distorts the stone symmetry. Furthermore, one long stone side is like a U-shaped bracket educated; the other long stone side therefore acts like the outside of the U as a wedge the two adjacent stones in a cross connection, so that only one stone long side is one real composite effect in the sense explained above. In addition, when laying in a cross connection the stones every second row of stones are rotated by 180 ° against each other, which is the laying difficult. The oblique offset of the long stone sides against each other also results in a The stone cross-section is not uniform in the longitudinal direction, which increases the susceptibility to breakage. Eventually they will not coincide with the corners of the baseline circumscribing the two squares Stone corners formed by crests of indentations and protrusions, thus putting together with the U-shaped basic shape a stacking of the stones on their provided with the teeth Stone sides is at least very difficult.

The invention is based on the object of improving the composite paving stone so that all of the above Disadvantages, which for the most part also have different types of composite paving stones (e.g. according to the Belgian patent specification 564 917 or German patent specification 960 359) are peculiar without acceptance other disadvantages are avoided at the same time.

The solution to this problem is according to the invention in the case of the composite paving stone of the aforementioned type achieved in that all the side sections, as known per se, in a zigzag order the baseline and, as is also known per se, are arranged centrally symmetrically.

The zigzag teeth are for example of one. also four-sided interlocked composite paving stone known, but its baseline is not two

ίο circumscribes squares and each other facing stone side pairs cannot be converted into one another by a parallel shift (German utility model 1898 954). The central symmetry is known from another Composite paving stone (Belgian patent 564 917) known per se, but its base line also does not circumscribe two squares in which the side sections inclined to the base line make up only about half of the associated side length and also in the cross connection it is necessary to rotate the stones of successive rows of stones by 180 ° relative to one another is.

The composite paving stone according to the invention is characterized by a better distribution of the interlocking forces over the entire length of the stone, with all the side sections at an angle to the base line are. It is stackable on all sides better than the well-known stone and shows one through the symmetry conditional better handling. In addition, it can be laid in a cross connection without mutual Rotate the stones consecutively! Lay rows of stones by 180 °. In this cross connection, but also in the following still to be considered writing compound in a herringbone pattern, not only one, but both have a long effect Stone sides as a bracket for two adjacent stones. The stone does not show at any point a weakened cross section; with the fact.

the fact that the stone shows no acute-angled protrusions or corners by its genus is evident thus also superior strength and no tendency to fracture.

It should also be noted that from the central symmetry together with the zigzag shape .urA, the baseline circumscribing two squares also dk Position of the right-angled corners of the stone on the corners of the rectangle described by the baseline follows. Finally, according to the particular genre that is preferred, all Side sections on the short stone sides are of the same length, from which in turn, together with dei Other features of the invention include the same length of the side sections on the long stone sides with the exception of the middle follows, where the side sections as a result of the centrally symmetrical! Connection are twice as long, there is an advantageous toothing with a fan-shaped mold construction depth. There is no protrusion or indentation extending to the corner of the stone, and the blunt angled apex of the projections and indentations conditions are each the same distance from the base line The composite paving stone is preferably g <-
