Definitions

  • the present invention relates to a structural element and a shaft element produced with the structural element and a shaft for a trench.
  • Trenches are used to take up, store and release a fluid, especially rainwater.
  • a shaft is provided for access to such a trench so that inspections, maintenance and cleaning of the trench can be carried out from there.
  • These shafts are complex to manufacture from polymer material, in which they are either welded together from semi-finished products, or are produced in a blow molding process or in a rotary sintering process.
  • the wall thicknesses of the shaft or shaft element are uneven, so that either the stability of these shafts or shaft elements is in need of improvement, or - in order to counteract this - a high wall thickness must be formed, which requires increased use of material.
  • a component for producing a manhole element completely solves the task if it is provided that the component is essentially plate-shaped with a first side and a second side opposite the first side, each flat and are arranged substantially parallel to each other, with a third side and a fourth side opposite the third side, wherein connecting means are provided on the third side and on the fourth side, such that a first connecting means on the third side and a second connecting means on the fourth side is formed, and a fifth side and a sixth side, wherein the sixth side is opposite to the fifth side and both are each arranged flat and substantially parallel to one another, connection means being provided on the fifth side and on the sixth side, such that a third connection means is formed on the fifth side and a fourth connection means is formed on the sixth side, the first Connecting means on the third side and the second connecting means on the fourth side are designed to be congruent to one another in order to establish a connection state in one spatial direction between two adjacent identical components, and wherein the third connecting means on the fifth side
  • the component for producing a shaft element can be designed to be particularly stable in this way. Appropriate precautions can thus also be taken so that the connection of the components to one another to form the shaft element is designed to be very solid.
  • 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 so that they are congruent to one another that when a connection state is established between two adjacent same 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.
  • a very favorable 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 so that they are congruent to one another when a connection state is established between two adjacent ones Components these are arranged in alignment or approximately in alignment with respect to the orientation of the respective first side of the components.

  • the projection has, at least in sections, the contour of a circular ring, in particular the contour of a quarter circular ring.
  • an opening which is delimited by the projections can be formed when a manhole element is produced from four identical components.
  • Such an opening of 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 a polymer material or contains one, the polymer material being selected from a thermoplastic, in particular a polyolefin such as polypropylene (PP), polyethylene (PE), polybutylene (PB), their copolymers and mixed compositions.
