Novel manhole cover

Affiliated technical field:

The utility model relates to a kind of manhole cover, especially structure advanced person, support force strong, use that steel are few, carrying weight load is big, indeformable, pressure is not bad, in light weight, cost is low, the novel manhole cover of long service life, theft protection, can guarantee vehicle and pedestrian's safety.

Background technology

The sewer manhole cover that uses on the highway is generally all made with iron casting at present, can carry bigger weight load, but it is big with the iron amount, the manufacturing cost height be the more important thing is, because the recovery utilization rate height of iron, price is also somewhat expensive, the thief is lucrative, so the cast iron manhole cover is stolen by madness, has caused a lot of cloudy wells not have lid to form the tiger mouth of eating the people.The generation of vehicle and personnel casualty accidents is often arranged, very dangerous, people are for vehicle and pedestrains safety, for antitheft, adopted the reinforced cement concrete structure or made manhole cover, but shortcoming is:, do not carry the weight load all without usefulness with composite material, easy deformation and damage, also very dangerous.

Summary of the invention:

In order to solve the difficult problem that existing manhole cover is antitheft and carrying weight load deformation damages, I am according to building structure and the steel work and the use of factory building structure and steel work and the large bridge and the railway bridge large span of large-scale large span of modern times The reinforced cement concrete structure and the use of font

The steel work of font, utilize the load-bearing principle of " column supports very heavy ", develop a kind of structure advanced person, support force strong, use that steel are few, carrying weight load is big, indeformable, pressures is not bad, in light weight, cost is low, long service life, can guarantee to be fit to the novel manhole cover of vehicle and pedestrains safety, theft protection use and popularization.

The utility model, mainly by sheet iron bar and auxiliary material, cement, yellow sand, handstone or composite material are formed.

The technical scheme that its technical problem that solves the utility model adopts is: do not have now ready-made small-sized on the market

Type and

The structural section supply, we just make of the 1-2mm sheet iron ourselves.Needs according to carrying weight load, also can make of thicker iron sheets, we earlier are cut into iron sheet the iron straps of two kinds of different size width of " wide " " narrow ", cut off according to the length needs, and are used for interconnective hole when being provided with a plurality of cast auxiliary material on iron straps.We are according to the load-bearing principle of " column supports very heavy ".So iron straps is stood vertically end face

Font.Again according to product specification size needs, the iron straps that stands vertically is welded into the frame of circle, square and rectangle or other shape.In frame, also iron straps is holded up again

Font, the iron straps support force that erects like this is very strong, can carry the weight load, many iron straps that erect is intersected in length and breadth to be welded into network again bracket end face and frame welding.Weld the vertical type network with iron straps like this, just can carry the weight load.If length, span is long or the diameter span is bigger, can on iron straps, presses reinforcing rib its end face is become Type, as required can also several roads of multiple pressure reinforcing rib, the weight load of such iron straps carrying is just bigger, also can be on the iron bar of netted up-right support or below again in the downhand welding iron straps of " narrow " its end face is become

Or Type, such structure network can carry quite heavy weight load, if length, span, diameter span, carrying capacity are all quite big, we can be on netted upright iron straps and the burn-on iron straps of " narrow " of lower plane, and its end face is become

Font, such net structure support just can be carried quite heavy weight load.The iron straps that stands vertically in a word is wide more, thick more, the weight load of carrying is just big more.So we will come choice structure and materials according to the load of carrying weight.But no matter be

Or

Or

Or

Or

The type support all be can't do without standing vertically The contribution of font iron straps.The weight of all carryings load all be by

The iron straps that font stands vertically supports, and the weight load can be decomposed, decomposes on the cloudy well seat fast to four limits fast, so just can reduce the weight load of manhole cover, makes its indeformable pressure not bad.Can make iron straps

With
