Definitions

  • the present invention relates to a structural element and a shaft for a drainage ditch, formed from at least two shaft elements which are manufactured from a plurality of the structural elements.
  • Infiltration trenches are used to collect, store, and discharge a fluid, particularly rainwater.
  • a shaft is provided to provide access to such a trench, allowing inspections, maintenance, and cleaning of the trench.
  • These shafts are complex to manufacture from polymer materials, either by welding them together from semi-finished products or by blow molding or rotational molding.
  • the wall thicknesses of the shaft or shaft element are uneven with the blow molding and rotational molding processes. Therefore, either the stability of these shafts or shaft elements needs to be improved, or—to counteract this—a thicker wall must be created, which requires increased material usage.
  • a component which can be used in a variety of ways to construct a water absorption device, wherein the component is flat, has several sides and connecting means to connect such components to one another.
  • a water absorption device comprising a plurality of identical components, wherein the component has surfaces and sides, and wherein mutually adapted connecting means are designed to connect several such components to form an arrangement.
  • a further water storage device comprising a concrete base plate laid on a lower part of a hole dug in the ground, a storage assembly provided on the base plate and housed in the hole, a square tubular concrete side wall provided around the storage assembly, and a side wall forming member configured to form the side wall into a square frame shape.
  • the storage assembly includes a plurality of square, tabular partition plates, tubular spacers connected to the partition plates, and an outermost layer portion provided on the outermost side of the storage assembly.
  • the sidewall forming member includes quadrangular tubular multi-stage inner molds formed from a plurality of first plate members, a plurality of vertical reinforcing bars inserted into the multi-stage partition plates, and a quadrangular tubular single-stage outer mold containing a plurality of second plate members through a plurality of separators.
  • the structural element used to create a shaft element can be designed to be particularly stable. Appropriate precautions can also be taken to ensure that the structural elements are very firmly connected to each other to form the shaft element.
  • the component is designed in such a way that the first connecting means on the third side and the second connecting means on the fourth side are designed congruently to one another in such a way that when a connection state is established between two adjacent identical components, by connecting the first connecting means on the third side of the first component to the second connecting means on the fourth side of the second component or by connecting the second connecting means on the fourth side of the first component to the first connecting means on the third side of the second component, the components are arranged at an angle of 90° or approximately 90° with respect to the orientation of the respective first side of the components.
  • Such a shaft element can be assembled from four individual identical components, each connected to the other at an angle of 90° or approximately 90°.
  • a very advantageous further development of the present invention can consist in that the component is designed in such a way that the third connecting means on the fifth side and the fourth connecting means on the sixth side are designed congruently to one another in such a way that when a connection state is established between two adjacent identical components, these are arranged in alignment or approximately in alignment with respect to the orientation of the respective first side of the components.
  • shaft elements can be stacked in a simple manner by arranging them in alignment one above the other and establishing the connection state with the aid of the connecting means so that the individual shaft elements are firmly connected to one another, whereby a shaft is formed from at least two shaft elements.
  • the first connecting means on the third side and the second connecting means on the fourth side each have two rear gripping sections.
  • first and second connecting means By providing several rear gripping sections on the first and second connecting means, a particularly stable, secure and firm connection of two components arranged next to one another can be achieved and ensured.
  • the component of the present invention can be designed in a particularly practical manner if it is provided that a projection projects approximately vertically from the second side, which projection is preferably formed at the end of the second side in the direction of the sixth side.
  • Such a projection is particularly practical for sections of a shaft or shaft element that, when installed underground, are aligned either in or against the direction of gravity. This makes it particularly easy to close the shaft in or against the direction of gravity by arranging, attaching, or assigning covers, adapters, or similar devices to the projections or with the aid of the projections.
  • the projection has at least in sections the contour of a circular ring, in particular the contour of a quarter-circular ring.
  • an opening can be formed during the manufacture of a shaft element from four identical components, which is bordered by the projections.
  • Such an opening in a shaft element can advantageously be used as access to the shaft or shaft element.
  • the component is designed in such a way that it consists of or contains a polymer material, wherein the polymer material is selected from a thermoplastic, in particular from a polyolefin, such as polypropylene (PP), polyethylene (PE), polybutylene (PB), their copolymers and mixed compositions.
  • a polymer material is selected from a thermoplastic, in particular from a polyolefin, such as polypropylene (PP), polyethylene (PE), polybutylene (PB), their copolymers and mixed compositions.
  • Fiber-reinforced polymer materials and/or mineral-filled polymer materials can also be used advantageously.
  • Long and short fibers are suitable. These can be selected from mineral fibers and synthetic reinforcing fibers. Examples include fibers from glass, polyamide, aramid, carbon, polyester, and others. Natural reinforcing fibers from plants, such as cotton, kapok, poplar down, bamboo, nettle, hemp, jute, linen, ramie, wood, sisal, coconut, and Manila hardboard, can also be used. Suitable mineral fillers include chalk, talc, mica, serpentine, vermiculite, muscovite, kaolinite, and others.
