Definitions

  • Manhole covers are usually inserted in roadway openings and rest upon annular bases made of concrete or other materials that are extremely resistant against heavy loads and that, as well as realizing the supporting bases for the manhole covers, also realize the walls of the drain well.
  • drains are realized for discharging water or for other purposes. These drains are usually communicating with the outside through conduits 10 or drain wells having walls 11 normally made of concrete. A manhole cover 12 is usually resting on the extremities of the walls 11 so as to be level to the road's surface.
  • a frame is inserted, consisting of two separate sections 13 and 14.
  • Section 13 which has an L shaped cross section, rests directly on the extremities of walls 11. It is also provided with a plurality of holes 15 in correspondence of which there are respective screw nuts 16 which are carried by section 13 itself.
  • Section 14 instead, has a substantially T shaped cross section.
  • the central flange 17 is provided with a plurality of threaded pins 18 that are welded on it and that are meant to be screwed into nuts 16, pass through holes 15 of section 13 and slip into cavities 19 obtained in the walls 11.
  • the manhole cover 12 will stand on the flanges 17 of T shaped section 14 while the other two flanges of such section, that is the superior flange 20 and the inferior flange 21 will form respectively an element for containing the manhole cover sideways and a guiding element for the vertical translation for the section 14 laterally to the walls 11.
  • the adjustment of the height of the section 14 may have an infinite number of positions, so that the alignment of the manhole cover 12 with respect to the road surface is always guaranteed. It can be understood that this kind of adjustment is extremely easy and quick, and that it will only be necessary to choose adequate dimensions for sections 13 and 14, for pins 18 and for nuts 16 to make the whole structure extremely rigid and reliable, as if the manhole cover was resting directly upon the concrete base that actually consists of the walls 11.
  • these can be covered by elastic sleeves 22 that prevent them from infiltrations from the outside and avoid the leakage of lubricant grease that is spreaded on the pins 18 and is applied inside the cavities 19 of the walls 11 so to guarantee the correct operation of the device.
  • a screw nut 30 is welded on the inferior surface of the central flange 17 of section 14.
  • a threaded pin 18 is screwed at first into nut 30, then into a second nut 31 and finally into a lock nut 32; these last two nuts grip the superior flange 33 of a C shaped section 34; a through hole 35, in which the threaded pin 18 is inserted, is obtained in flange 33.
  • the inferior flange 36 of section 34 stands directly on the basement 37 of the conduit 10.
  • a horizontal flange 38 is welded on the vertical flange 39 of section 34 near said basement sticking out towards the outside of the conduit 10.
  • Such external flange 38 represents the lower limit stop for section 14.
  • the height adjustment of said section is carried out as follows: first of all lock nut 32 has to be unscrewed; then nut 31 has to be tightened or untightened to raise or lower section 14 and consequently the manhole cover 12.
  • a sleeve 40 is welded to flange 33 to protect pin 18 from any dirt infiltration, as done in a similar way by the elastic sleeves 22 shown in fig. 1.
  • the frame When installed, the frame is fitted on top of the basement 37, and the concrete for realizing the walls 41 is casted externally with respect to the frame, with section 14 acting as a formwork. After the concrete setting, the height of section 14 can be adjusted.
  • the external surfaces of the latter may be previously spreaded with grease before casting the concrete.
