Description
Technical field
The utility model belongs to well lid technical field, and in particular to a kind of bearing type fabric reinforcement concrete manhole cover.
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.
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
Manhole cover.
A kind of bearing type fabric reinforcement concrete manhole cover, including outer rim, concrete, upper skeleton, lower skeleton, feature
It is: is welded with supporting plate on the inside of the outer rim top, the supporting plate is annular shape, is equipped in the outer rim interior zone
Upper skeleton, lower skeleton, the upper skeleton, lower skeleton are welded by round steel, upper skeleton, lower skeleton section be spoke
Shape is welded on the inner wall of supporting plate on the outside of the upper skeleton, is welded on the inner wall of outer rim on the outside of the lower skeleton, institute
It is integral by the connecting rod connection of vertical direction to state upper skeleton, lower skeleton, concrete has been poured in the interior zone, it is described
It is mixed with steel fibre in concrete, is equipped with central boss at the center on the concrete top, the side of the central boss is set
Having section is the supporting block of triangle.
Preferably, the side of the concrete is equipped with manhole, and the manhole is through-hole.
Preferably, the upper skeleton is parallel with the upper surface of concrete.
Preferably, the vertical interval between the upper surface and supporting plate of the central boss is 30-70mm.
Compared with prior art, the utility model has the beneficial effects that
When the utility model is used, central boss towards lower cover in walling crib, supporting plate is contacted with the step in walling crib, when need
When overhauling, using hook from manhole by well lid pull-up；By in concrete mixing steel fibre, to greatly improve well lid
Intensity has the advantages that intensity height, long service life, safety are good；It can be further increased by setting upper skeleton, lower skeleton
The intensity of well lid；Well lid and the contact position of walling crib are all made of metal material, can further prolong the service life.

Specific embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of bearing type fabric reinforcement concrete manhole cover, including outer rim 1, concrete
4, upper skeleton 3, lower skeleton 7, it is characterised in that: supporting plate 2 is welded on the inside of 1 top of outer rim, the supporting plate 2 is annulus
Shape, is equipped with upper skeleton 3, lower skeleton 7 in 1 interior zone of outer rim, the upper skeleton 3, lower skeleton 7 welded by round steel and
Section at, upper skeleton 3, lower skeleton 7 is spoke-like, and the outside of the upper skeleton 3 is welded on the inner wall of supporting plate 2, described
The outside of lower skeleton 7 is welded on the inner wall of outer rim 1, and the upper skeleton 3, lower skeleton 7 are connected by the connecting rod 5 of vertical direction
It is integral, concrete 4 has been poured in the interior zone, has been mixed with steel fibre in the concrete 4, on the concrete 4
Central boss 6 is equipped at the center in portion, the side of the central boss 6 is equipped with the supporting block 8 that section is triangle.
The side of the concrete 4 is equipped with manhole 9, and the manhole 9 is through-hole.
The upper skeleton 3 is parallel with the upper surface of concrete 4.
Vertical interval between the upper surface and supporting plate 2 of the central boss 6 is 30-70mm.
The working principle of the utility model is:
