Abstract
The utility model relates to a steel limit hybrid fiber concrete well lid, its characterized in that well lid main part comprises the hybrid fiber concrete, and its peripheral part parcel is in channel-section steel cover structure, and the channel-section steel cover has higher authority, lower level and side, wherein has the interior contained angle that inclines of 1-5 degrees between side and the vertical direction. The manhole cover has the advantages of simple structure and low manufacturing cost, can meet the requirements of theft prevention, tensile strength, bending resistance, impact resistance and fatigue resistance of the manhole cover, and can be widely applied to various pipeline inspection wellheads of municipal facilities.
Description
The utility model relates to a kind of well lid, specifically a kind of steel limit mixed-fiber reinforced concrete well lid.
Traditional well lid material is based on cast iron, and also useful ordinary reinforced concrete, is easily lost casting iron well lid cost height, thereby often causes very big economic loss and casualties; And reinforced concrete well lid can be avoided the generation of above-mentioned incident, but the shock resistance of invar reinforced concrete well lid is lower, very easily damaged in carrying, construction and use, again because concrete has certain porosity, the inner reinforcing bar of well lid is vulnerable to the corrosion of the pernicious gas in the underground pipeline, therefore can not use for a long time.And the effect that has high tensile, anti-shearing, shock resistance and antifatigue as raw-material well lid with mixed-fiber reinforced concrete, cost is low, can solve above-mentioned deficiency.But breakage is then caused easily if there is not the protection of other material in this raw-material well lid marginal portion; Only added the well lid of stirrup or other abrasion-resistant material and prior art adopts, and existed again between main body mixed-fiber reinforced concrete and the skirt materials and combine the problem that differs from the edge of mixed-fiber reinforced concrete well lid.
The purpose of this utility model is the deficiency that overcomes above-mentioned well lid, and provides a kind of simple in structure, can satisfy the tension of well lid, anti-folding, shock resistance and antifatigue requirement, and is cheap, and antitheft steel limit mixed-fiber reinforced concrete well lid.
The utility model is achieved in that
Steel of the present utility model limit mixed-fiber reinforced concrete well lid, main body is made of mixed fibrous concrete, and its peripheral part is wrapped in the channel-section steel nested structure, and the channel-section steel cover has top, bottom and side, wherein has the introversion angle of 1-5 degree between side and the vertical direction.
Steel of the present utility model limit mixed-fiber reinforced concrete well lid further has following feature:
The top of described channel-section steel cover is concordant with the well lid face.
The inboard of described mixed-fiber reinforced concrete well lid is the fish belly shape.
Steel of the present utility model limit mixed-fiber reinforced concrete well lid, described well lid matches with step on the mixed-fiber reinforced concrete walling crib.
There is identical tapering on step part that matches with well lid on the described walling crib and well lid steel avris limit.
The upper surface of described walling crib is provided with steel ring.
Steel of the present utility model limit mixed-fiber reinforced concrete well lid owing to used composite fibre coagulation scholar raw material, has not only guaranteed its requirement of strength, and has fundamentally solved the stolen problem of well lid.Its peripheral channel-section steel cover plays a very good protection to the mixed-fiber reinforced concrete of inside, has prevented the breakage of concrete material; And combine well with the concrete of inside, avoided only stirrup or other reinforcement not firm problem of combination that protective material brought being set at peripheral part.Simultaneously, the fitting face between channel-section steel cover side and the walling crib has certain tapering, and the edge carrying evenly has a load plane under the carrying conical surface, has not only strengthened the stability of well lid, reduces bearing surface beating and noise when vehicle crosses.And can avoid excessive and phenomenon that cause walling crib to rupture to the bearing capacity of walling crib.The fish belly shape structure of well lid can satisfy its mechanical property to greatest extent.
Fig. 1 is a generalized section of the present utility model.
Fig. 1 a represents the cross-section structure of well lid of the present utility model.
Fig. 1 b represents the cross-section structure of the walling crib that matches with well lid.
Below in conjunction with accompanying drawing embodiment of the present utility model is explained.
The periphery of the well lid 2 of the steel limit mixed-fiber reinforced concrete of present embodiment is a channel-section steel cover 1, the introversion angle theta that the side of channel-section steel cover 1 and vertical direction have the 2-3 degree, its top is mutually concordant with the well lid face, the inboard of well lid 2 is the fish belly shape, well lid 2 matches with step on the walling crib 3, the side and the bottom of the channel-section steel cover 1 on the well lid match with limit 5 and limit 4 on the walling crib 3 respectively, and there is identical tapering on limit 5 with the side of channel-section steel cover 1.Walling crib 3 upper surfaces further are provided with steel ring 7, and walling crib 3 its inner rising are strengthened and protective effect.Further, mixed-fiber reinforced concrete well lid of the present utility model can also be provided with hole for hoist and bar shaped asperity with reference to prior art on well lid, and the latter can increase anti-wear performance, and is anti-skidding, attractive in appearance, because said structure belongs to universal design, does not illustrate in the drawings.The steel limit mixed-fiber reinforced concrete well lid of present embodiment has in light weight, intensity height, characteristics such as long service life.
