Definitions

  • the invention relates to a concrete block according to the preamble of patent claim 1 and a method for producing a concrete block according to the preamble of claims 12 and 15.
  • Concrete blocks in particular paving stones, steps, wall and boundary stones made of concrete are well known from the prior art. Such concrete blocks are often used in the construction of roads, traffic routes and landscaping for the production of surface coverings, walls, stairs or other structures built into the ground.
  • such concrete blocks or concrete slabs are often used in urban areas to create surface coverings, for example to design squares and streets.
  • Such surface coverings are particularly suitable not only to be walked on by pedestrians, but also to be driven on by vehicles. Therefore, surface coverings produced from the concrete blocks or concrete slabs mentioned are often subject to a strong dynamic load as a result of the acceleration and braking of passenger cars, trucks or other heavy goods vehicles. This can damage the traffic area created with the concrete blocks.
  • displacement safeguards are already used in the prior art, which can be designed in different ways.
  • Known displacement locks have in common that they are used when laying the concrete blocks or concrete slabs in such a way that they rest against the concrete blocks or concrete slabs and cause support or anchoring of them in the subsoil or the bedding or the base course at least in a predetermined displacement direction.
  • the threaded pins can also extend from the underside of the base plate through the threaded hole over the top side of the base plate and protrude upwards from the latter.
  • contact surfaces or contact webs are created for the side surfaces of the concrete blocks or concrete slabs, which effectively prevent displacement thereof in at least one displacement direction.
  • Concrete blocks within the meaning of the invention can in particular be concrete slabs, paving stones, steps, wall and boundary stones made of concrete.
  • the present invention relates to a concrete block in which at least one plate-shaped holding element is integrated into the concrete block body in the area of the concrete block underside, wherein the plate-shaped holding element has at least one fastening opening which is accessible from the concrete block underside and extends in the direction of the concrete block upper side for receiving and fastening a Has shift locking element. It is particularly advantageous that part of the intended displacement system is already firmly integrated into the stone body during the production of the concrete block, in particular paving stone made of concrete, preferably in the area of the underside of the stone, so that the concrete block system can be anchored centrally in the subsurface.
  • the Anti-displacement elements only before or during laying, that is, introduced on the construction site into the holding element prepared in the concrete block, the number and / or arrangement of which can be selected depending on the application. For this purpose, for example, several fastening openings can be provided, distributed over the plate-shaped holding element.
  • the integration of the shift protection system into the concrete block also enables easier transport.
  • the at least one plate-shaped holding element is received in the concrete block body flush with the underside of the concrete block. This enables optimal use of the shift protection.
  • the shift locking element is also advantageously formed by an elongated and / or rod-shaped locking pin or locking pin.
  • the anti-shift element can be implemented at least in sections in the form of a profile element.
  • the at least one plate-shaped holding element and / or the anti-displacement element are made of metal or plastic, so that the absorption of high dynamic forces is also ensured.
  • the at least one fastening opening is through a hole or through hole, preferably each with an internal thread.
  • the hole or through-hole can have a hexagonal cross-section, which is designed to receive a hexagonal screw nut, preferably in a form-fitting manner.
  • the anti-displacement element has at least one free-end connection section via which a detachable screw or plug connection can be established with the plate-shaped holding element, namely by screwing or plugging into the fastening opening.
  • connection section on the free end for producing the releasable screw connection can have an external thread, at least in sections.
  • the free-end connection section for producing the detachable plug connection can have, at least in sections, a cross section deviating from the circular shape and / or plug connection means.
  • the at least one plate-shaped holding element and / or the anti-displacement element form a displacement protection system that is at least partially integrated in the concrete block.
  • the plate-shaped holding element can have at least one anchoring or reinforcement element protruding from the top in the direction of the concrete block top, whereby an improved integration into the concrete is achieved.
  • the plate-shaped holding element also advantageously has a right-angled or L-shaped cross section.
  • the invention also relates to a method for producing a concrete block, in which a formwork is provided with at least one production plate, in which concrete is introduced into the formwork, the introduced concrete is then compacted and cured and the formwork is removed from the concrete.
  • a plate-shaped holding element Before the concrete is introduced into the formwork on the production plate, at least one plate-shaped holding element is particularly advantageously introduced and fixed in a precisely positional and positional manner.
  • the location and / or position in and / or on which the at least one plate-shaped holding element is to be introduced and fixed is advantageously projected onto the production plate by means of display means, preferably a laser pointer unit.
  • the plate-shaped holding element can be held or fixed on the production plate by applying a magnetic force to a permanent magnet arranged in or on the plate-shaped holding element.
  • a formwork is provided and concrete is introduced into the formwork, the introduced concrete then being compacted and hardened and the formwork being removed from the concrete.
  • at least one plate-shaped holding element is particularly advantageous in the precise position and position in the Formwork located, preferably already pre-compacted concrete introduced and then compacted or further compacted.
  • Figure 1 is shown by way of example a schematic and perspective view of a concrete block 1 according to the invention.
  • the concrete block 1 is preferably designed in the form of a surface element that can be laid in a composite to create a surface covering.
  • concrete block or concrete slab is understood to mean essentially structurally identical elements that can be used in a manner known per se to create a surface covering.

  • Figure 3 shows a schematic side view of the concrete block body 2 according to the invention, the location and position of the plate-shaped holding element 3 integrated in the concrete block body 2 being indicated by means of a dotted line.
  • Figure 4 shows, by way of example, a section along the two fastening openings 4, 4 ', each with a displacement security element 5, 5' received therein, which in the present exemplary embodiment is formed in the form of a so-called "spike".
  • one or more such plate-shaped holding elements 3 can be accommodated in the concrete block body 3, in particular in almost any rotational position in relation to the central longitudinal axis MLA of the concrete block 1. It is particularly advantageous through the selection of the rotational angle position of the plate-shaped holding element 3 in relation to the central longitudinal axis MLA the shift direction can be set in which the effective shift protection direction is set
