Definitions

  • the invention relates to a manhole cover according to the preamble of claim 1.
  • the invention relates to the construction and covering of shafts and the drainage of rainwater and other liquids from buildings of various types, in particular from streets, squares and bridges used.
  • these structures have a bitumen, concrete or cement layer, under which there is a substructure, which can consist of different materials, for example gravel, sand, concrete or the like.
  • a sealing film is placed between the substructure and the top layer to protect the substructure from the ingress of moisture.
  • the rainwater and other liquids accumulating on the above-mentioned structures must be drained off, using sewer shafts and water inlets of various types.
  • the From GB-A-1 249 860 a generic manhole cover is known, in which the base frame has pockets on the underside in which heads the screw bolts protrude, while the same are guided through holes in the frame and secured by nuts arranged on both sides or vice versa Bolts are supported in the frame and the base frame is secured by nuts.
  • the object of the invention is a Specify the shaft cover in which the base frame is easily and effortlessly adjustable in height and inclination and in which the full and secure support of the base frame is ensured even at larger angles of inclination. This object is achieved by the features in the characterizing part of claim 1.
  • the shaft cover shown in FIG. 1 is composed of a housing 1, a base frame 2 that can be inserted into the housing and adjusting means 3.
  • the housing 1 can also have an outer flange 4, which is adjoined by an approximately vertical or inclined wall part 5.
  • the outlet 7 can also be provided on the side of the wall part 5.
  • pockets 9 are provided in the vicinity of the wall part, which are partially opened upwards by a recess 10.
  • the pockets 9, of which at least three are arranged on the inner circumference of the wall part 5, have a rectangular shape (FIG. 2), while the recess 10 has a slot shape with a rounded base.
  • the base part 6 can have a greater wall thickness, which extends over the entire inner circumference of the housing 1 or can only be provided locally.
  • the base frame 2 is composed of two parts, one part of which is designed as a base frame upper part 11 and the other part as a base frame and lower part 12. However, it is also possible to manufacture the base frame 2 from one piece. The division into upper part 11 and lower part 12 is done for practical reasons, for example to simplify the manufacture.
  • the base frame upper part 11 and the base frame lower part 12 can also be firmly connected to one another, for example by screwing or welding (not shown).
  • the bores 13 are machined in the base frame lower part 12.
  • the bores 13 can have a cylindrical shape or, as shown in FIG. 1, a funnel shape that widens on both sides.
  • the number of holes 13 coincides with the number of pockets 9 and, moreover, the holes 13 are aligned with pockets 9.
  • a screw bolt 14 extends through the bores 13, the lower end 15 of which projects through the recesses 10 into the pockets 9.
  • a screw nut 16 is inserted, the outer contour of which is rectangular or square and fits into the pocket 9 with little side play. If the lower end 15 of the screw bolt 14 is now screwed into the screw nut 16, the screw nut 16 cannot rotate in the pocket 9, so that it can be screwed onto the lower end 15 until it fits snugly against the ceiling of the pocket 9 and forms a firm connection with the bottom part 6.
  • a pair of screw nuts 17, 18 are screwed onto the screw bolts 14, of which one screw nut 17 lies on the underside and the other screw nut 18 lies on the upper side of the base frame lower part 12.
  • a washer 19 is inserted, the side surface of which is directed toward the base frame lower part 12, that is to say is provided with a convex spherical surface 20.
  • the adjustment means 3, that is, the bolts 14, the nuts 17, 18 and the washers 19, allow an exact adjustment of the height of the base frame 2. But also a certain inclination can be achieved by the spherical surfaces 20 of the washers 19 and by the two sides expanding parts of the base frame 2 can be adjusted without jamming.
  • a hexagon socket, a cross-slot bore 21 or a slot for tightening the screw bolt 14 can be provided with an appropriate key or screwdriver.
  • the upper end 22 can also be designed as an external hexagon.
  • the manhole cover shown in FIG. 3 has the same adjustment means 3 as the manhole cover according to FIG. 1, which is why the chosen reference symbols have the same meaning as in FIG. 1.
  • the screw bolts 14 are also fastened in the base frame 2 in the same way as in the manhole cover according to FIG. a shoulder, a collar or a lock nut.
  • the base frame 2 is formed in one piece, which is arranged in place of the housing 1 in FIG. 1 in a frame 23 which delimits the upper end of a vertical shaft 24.
  • the frame 23 has ribs 25 arranged on the outer circumference, its shaft-side end having an outer flange 26 and an inner flange 27 of greater wall thickness, in which the pockets 9 for fastening the screw bolts 14 also lie.
  • the upper edge of the base frame 2 is designed as a seat 30, in which a manhole cover or a manhole grate (not shown) can be used.
  • the two described, adjustable in height and inclination manhole covers according to FIGS. 1 and 2 have a simple construction.
  • the base frame 2 can by means of Screw nuts 17, 18 can be set exactly, the screw nut 18, as a lock nut, preventing the position of the base frame 2 from shifting even under high loads and eccentric force application.
  • the same also applies to the screwing of the screw bolts 14 in the base part 6 of the housing 1 or in the inner flange 27 of the frame 23.
  • the number of bolts is determined by the size of the manhole cover and the load to be borne.
  • the cavity under the base frame 2 can be mortared if necessary; but this is not necessary.
  • the housing 1 can be laid on its own and the base frame 2 can be used subsequently. This makes it easier to lay the manhole cover in the ground.
