Technical field
The utility model belongs to well lid technical field, and in particular to a kind of bearing type steel fibre concrete manhole magnesium iron bone
Frame.
Background technique
Municipal works inspection shaft well lid is usually cylinder iron made.It is made of panel and ribs, is circular.Ribs is
Groined type or radiation arrangement.It has the disadvantage in that one is with a large amount of cast irons, structure bulky, and every piece is both needed to make
Make sand mold casting, complex process is at high cost, and production environment is severe；Second is that cast iron is fragile material, shock resistance is poor；Thirdly
It is to be easy corrosion；The fourth is being easily stolen surreptitiously.Successfully steel fibre concrete manhole is studied from scientific research institution of China Construction First Division in 1989, and
Thereafter by Zhongjian Building Science & Technology Inst., Beijing study successfully enhanced fiber mortar and fiber concrete heavy well cover with
It has been generalized to nearly 30 areas in the whole nation, has achieved economic benefit and social benefit outstanding.This well lid can only be with phase therewith
Matched concrete walling crib matches.
Existing concrete manhole cover often haves the defects that intensity is low, when rolling by automobile, lorry, easily occurs
Crackle, service life is shorter, and there are biggish security risks.And the principal element of this problem is caused to be its skeleton.
Utility model content
The purpose of the utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of bearing type steel fiber reinforced concrete
Well lid magnesium iron skeleton.
A kind of bearing type steel fibre concrete manhole magnesium iron skeleton, including walling crib, well lid, it is characterised in that: the well lid
By outer girth sheets, plectane, reinforcing rib, inner ring board group at the outside of the plectane is equipped with outer girth sheets, and the lower part at plectane center is equipped with
Interior girth sheets is equipped with the difference in height of 20-50mm, the interior girth sheets and outer ring between the interior girth sheets lower end surface and outer girth sheets lower end surface
It is connected between plate by reinforcing rib, the outside on the walling crib top is equipped with disk, and the middle part of walling crib is equipped with step, well lid insertion
Into the centre bore of walling crib, the outer girth sheets is ridden on the step, and supporting plate, the support are fixed on the inside of the walling crib lower part
Plate and annular shape, the top of the supporting plate are placed with lower support, and the lower end surface of the interior girth sheets is contacted with lower support abutting, described
Well lid is poured by spheroidal graphite cast-iron.
Preferably, the side of the plectane is equipped with manhole used for overhaul.
Preferably, the outer girth sheets, plectane, reinforcing rib, interior girth sheets are followed closely equipped with pawl.
Preferably, the section of the reinforcing rib is trapezium structure.
Preferably, the lower support is spoke-like, and lower support is poured by spheroidal graphite cast-iron.
Compared with prior art, the utility model has the beneficial effects that
When the utility model is used, the region in well lid pours the concrete for being mixed with steel fibre, when needing in well
It when being overhauled, is inserted into manhole by hook, pull-up well lid, is opening lower support.Pass through setting reinforcing rib, interior
Girth sheets has the advantages that long service life, intensity are high, safety is good to greatly reinforce the mechanical strength of well lid；Pass through setting
Pawl nail, can connection between reinforced concrete and well lid, the mechanical strength of well lid can be further increased；Pass through setting lower
Support, so that interior girth sheets rides in lower support, plays the role of support, can further increase the bearing capacity of well lid.
