Definitions

  • the invention relates to an insert element for producing a drainage object or for locking a cover on a polymer concrete body or a concrete body, for example on a yard drain or on a drainage channel, and a yard drain.
  • Courtyard drains made of composite materials are known in the prior art. Furthermore, yard drains, which are composed of a modular system, are known. Such a modular system u. a. composed of a basic body, optionally a top element to adjust the yard drain to a floor level, and a cover element. The base body or the attachment element are designed to receive the cover element. For this purpose, the base body or the attachment element have cutouts which interact with a locking device of the cover element.
  • Courtyard drains of the type mentioned above are produced by casting processes.
  • the cutouts for the locking device are formed, for example, by slides or lost formwork, which are arranged on the base body or on the attachment element during the casting process. This can be at an upper edge of the Cut out air pockets or air bubbles. When the slider is removed, this leads to unevenness on the edge, which results in a deterioration in the locking security and visual defects.
  • the invention is therefore based on the object of specifying an insert element for producing a courtyard drain, which provides a receptacle for a locking element and a support surface for a cover and enables secure locking. Furthermore, the invention is based on the object of specifying a yard drain.
  • the object is achieved by an insert element, in particular for the production of a drainage object or for locking a cover on a polymer concrete body or a concrete body, for example on a yard drain or on a drainage channel which is cast with a composite material, in particular polymer concrete.
