Definitions
- the invention relates to an upper part for a shaft.
- Shaft tops are known from the prior art and usually have an outwardly curved shape. Due to this shape, these shaft tops have a good resistance to compressive forces exerted by the underground surrounding the shaft. In the area of the transition from shaft cone and shaft access part, however, there are always deformations. In this area, radially inwardly directed force components can cause the shaft top part to bend inwards at this point or to be pressed in over the tolerance range.
- EP 0 906 477 B1 discloses a top part for a manhole with an access part and a manhole cone which is connected to the access part and can be placed on a manhole ring with a peripheral edge on the side of the manhole cone opposite the access part, wherein the manhole cone is essentially a outwardly arched basic shape, wherein in the region of the transition from the access part to the manhole cone a substantially parallel to the plane in which the peripheral edge is located aligned reinforcing rib is provided on the outer surface of the manhole cone, which extends over the entire circumference.
- A1 shaft top part for a shaft is known with an access part and a shaft cone which is connected to an access part and with a connecting element on the opposite side of the access part of the shaft cone can be placed on a further shaft element, wherein the shaft cone a substantially outwardly arched basic shape, wherein the duct cone has at least 3 sections in which substantially mutually parallel stiffening elements are arranged.
- the object of the invention was to provide a shaft top with the lowest possible wall thickness, but great stability, which is easy to produce even with simple tools.
- the invention is therefore an upper part of a shaft, with an access part and a shaft cone, which is connected to an access part and with a connecting element on the access part opposite side of the shaft cone can be placed on a further shaft element, wherein the shaft cone a substantially Having convex basic shape, characterized in that in the region of the shaft dome stiffening structures are arranged on the inner surface of this shaft dome, which is substantially radially or parallel, angular or concentric of one or more imaginary points or lines inside or outside the dome on the extend curved shape of the shaft cone down.
- the shaft top according to the invention has the same wall thickness as the prior art higher load capacity. With significantly reduced wall thickness same load capacity is achieved.
- a connecting element is provided by means of which the shaft top according to the invention can be placed sealingly on other shaft parts.
- the stiffening structures of the shaft upper part according to the invention allow the resulting loads (for example, traffic load, pressure load) to be reliably reduced.
- the internal stiffening structures can be considered in cross-section as a rib, bead, bead, trapezoidal, diamond-shaped or I-beam semicircular, elliptical, square, triangular or optimized depending on the application polygonal structure, so that the stiffness of the curved basic shape of the shaft cone optimized becomes.
- the distances between the stiffening structures and the dimension of the stiffening structures are also optimized and executed depending on the geometry and load requirements.
- the internal stiffening structures are protected against damage by the filling material (earth, gravel, gravel and the like) or by manipulation (for example during installation). Therefore, a stable stability of the shaft top is guaranteed.
- the substantially smooth outer side also allows a more homogeneous compaction of the filling material than in known shaft tops.
- the shaft top may include further internal stiffening structures that may extend over the inner circumference.
- these elements can be viewed in cross-section as a rib, bead, bead, trapezoidal, diamond-shaped or I-beam semicircular, elliptical, square, triangular or designed as depending on the application optimized polygonal structure. They may be concentric, eccentric radial, or angular around an imaginary point inside or outside the dome.
- the upper part of the shaft may have, on its outer side, optionally circumferentially extending buoyancy securing elements, which may be in the form of ribs, webs, segments, tabs, knobs, tips and the like. In this case, these buoyancy securing elements can be arranged continuously or not continuously, depending on the shape, for example, in the form of concentric circles (from an imaginary center, which may be the same or different to the imaginary point from which the stiffening extend).
- the shape of the buoyancy protection elements can be optimized depending on the backfill material used.
- the access part can be arranged eccentrically or centrally, optionally holding elements can be provided inside.
- a device may be provided on the ring of the shaft top, which allows a centering of the upper part of a Schachtstoff- or -unterteil.
- This device can be designed as an optical marking or as a mechanical guide aid (for example as a guide pin or fork or the like).
- the upper shaft part according to the invention is preferably produced from thermoplastically processable plastics, preferably in an injection molding process.
- the shaft top according to the invention is, for example, for sewage shafts, water pump shafts, safety shafts, one-man Bunkers, water storage tanks, pellet storage tanks, geothermal storage tanks, service shafts (eg for electric cables).
- the shaft top according to the invention is shown in Figures 1 to 3.
