(54) Regulable manhole cover


(57) DEALS ON AN INDUSTRIAL INVENTION THAT DETECTES A SOLUTION FOR THE NEED TO REPLACE ON LEVEL THE MANHOLE-COVER (CLOSED OR GRATED), AS REGARDS OF A NEW LEVEL SURROUNDING PAVING.
THIS REPOSITIONING ON LEVEL IS CARRIED OUT WITHOUT UNWALL THE MANHOLE-COVER OUT OF ITS EXACT PLACE (PICTURE 2-3).
THE SOLUTION OF THE PROBLEM IS CARRIE OUT KEEPING UP WELL KNOW BULDING TECHNIQUE' USE, AND ALSO THE USUAL MATERIAL OF PRESENT MANHOLE-COVER (CAST IRONIC AND P.V.C.) BUT ADDING ON IT INSIDE A MECHANICAL DEVICE FOR THE HEIGHT'S REGOLATION (PICTURE 1).










Description

DISCLOSURE OF INDUSTRIAL INVENTION



[0001] On behalf of Sabellico Luigi, bom in Formia (LT) the 29 of June 1952 and there resident in Via delle Vigne s.n.c., as applicant, this report is been presented contained description of industrial invention.

[0002] The manhole cover in object represents a very innovation into the functional use of this road element, also keeping up, in its structure and typology (closed or grated) well know building technique' use and the usual material of present manhole cover (cast iron and p.v.c.).

[0003] It is common knowledge that a manhole cover is substantially an opened or detachable door from its below support-frame where it's mortised. The manhole's cover lifting allows the inspections and makes interventions on below services much easier.

[0004] The manholes cover, normally, are positioned and fixed into the concrete before the street's bituminition is done. They are concreted a few centimetres increased as regard the existent ground, so that laying low in advance street's mantle restoring it trimmed and levelled with the asphalt.

[0005] The subsequent and dues remaking of surface's bynder, that normally is high 3 centimetres for each layer, lets the standard manhole cover subordinate. It having been concreting with a previous level, remains obviously below the new street's level. To trim the gap one have got to intervene to detache it from the anchorage' concrete and subsequently replace it with the new street's level. The "adjustable manhole cover" contains a different functional that eliminates all that's works, expenses and discomforts of road' conditions.

[0006] The manhole cover in object is composed by two frames: one of those is fixed and remains anchored into the cement's maltha necessary for its fixing, the other one is sliding and reliftable as regards the first laying level with the easy substitution of "thickness" element below to each side of the sliding frame. The manufacture of thicknesses, with a large choice of measures, it made an easy levelling at the street, when it's been relayed the asphalt on it.

[0007] Apart from the functional innovation of the thicknesses, the "adjustable manhole cover" contains a further possibility of regulation situated on each angle of the cover.

[0008] Deals on to position a "bolt-foot" into a frame's notch where it remains completely in when it's in uselessness position.

[0009] Screwing down each "bolt-foot" tightening some thicknessed washer allows a perfect levelling of "adjustable manhole cover" to the surrounding street's level.

[0010] This remarkable regulation lets, besides, the elimination of concavity's defect which can be checked into the cast iron's manhole cover casting.

[0011] A shaky cover has an imperfect adherence with the support's frame and causes that annoying noise of metals collision when every single load passes on the manhole cover.

[0012] Illustration of "adjustable manhole cover" and its functioning:
  1. 1) Fixed frame (picture 1-A)
  2. 2) Sliding frame (picture 1-B)
  3. 3) Thickness element (picture 1-C)
  4. 4) Manhole's cover (picture 1-D)
  5. 5) "Bolt-Foot" (picture 1-E)


[0013] To relocate the manhole cover on new surrounding level (pictures 2 and 3) needs: to take off the sliding frame, to substitute the below thicknesses elements with those suitable for the new street's level height, to replace the sliding frame and to position the cover.
