Description
Technical field:
The utility model relates to a kind of well lid, relates in particular to a kind of steel limit steel fibrous concrete manhole cover.
Background technology:
In order to satisfy the requirement of well lid at aspects such as tension, anti-folding, shock resistance and antifatigues, and avoid easily losing, defective such as cost height, in the prior art, for example Chinese utility model patent ZL99213807.8 provides a kind of steel limit mixed-fiber reinforced concrete well lid, it comprises well lid main body that is mixed by steel fibre and concrete and the channel-section steel cover that is wrapped in described well lid body peripheral edge, the well lid main body is provided with hole for hoist, and well lid main body bottom is provided with the solid reinforcement of fish belly shape.The deficiency of this well lid is: 1, after installing and using a period of time on the road, foreign material such as the dust on the highway, sandstone enter in the gap of well lid and well lid bearing, and through reasons such as rainwater and automobile roll offs, well lid only is difficult to open with two holes for hoist; 2, the solid reinforcement of well lid main body bottom setting has satisfied the intensity of well lid to greatest extent, but has also made well lid weight increase greatly simultaneously, when needs are opened or are placed, use very inconvenient, simultaneously, because solid reinforcement materials are more, cause cost to increase.
The utility model content:
The technical problem that the utility model solves is the deficiency that overcomes above-mentioned prior art, and a kind of steel limit steel fibrous concrete manhole cover is provided, and it is not only opened easily, and on the basis of guaranteed strength, weight alleviates greatly, and is easy to use, also provides cost savings.
A kind of steel limit steel fibrous concrete manhole cover that provides according to the utility model, comprise well lid main body that mixes by steel fibre and concrete and the channel-section steel cover that is wrapped in described well lid body peripheral edge, described channel-section steel cover has top, bottom and side, and described channel-section steel puts and is provided with the sled hole; The bottom of described well lid main body is provided with many reinforcing ribs.
The utility model also has following attached technical characterictic:
The up-small and down-big semicircle shoulder hole of described sled Kong Weiyi, it is arranged on the outer edge of described channel-section steel cover and opening outwardly, and inside also is provided with and helps skid plate.
Described sled hole comprises last hole that is formed by the breach on the top of described channel-section steel cover and the following hole that is formed jointly by breach on the side of described channel-section steel cover and the breach on the described well lid main body, separates by the c-shaped steel plate in a cross section between described hole down and the described well lid main body; The described bottom surface that helps skid plate to be located at described channel-section steel cover top.
The described radius of going up the hole is 10～30mm, and the described radius in hole down is 14～34mm, and the thickness of described steel plate is 2～9mm.
The described radius of going up the hole is 20mm, and the described radius in hole down is 24mm, and the thickness of described steel plate is 5mm.
Described reinforcing rib is radial even distribution, and the inner is intersected and formed a round boss, and the height of described reinforcing rib outwards diminishes gradually from described round boss periphery.
Described reinforcing rib has 6.
Described well lid main body is provided with two holes for hoist, and described channel-section steel cover side and vertical direction have the introversion angle b of 1～5 degree.
According to a kind of steel limit steel fibrous concrete manhole cover that the utility model provides, prior art has following advantage relatively:
At first, the utility model puts at channel-section steel and is provided with the sled hole, when needs are opened well lid, can stretch in the sled hole with ripping bar earlier utilizes lever principle that well lid is pried open, can remove well lid easily by hole for hoist this moment again, thereby avoided in the prior art entering the phenomenon that is difficult to open that gap between well lid and the well lid bearing etc. is former thereby cause because of foreign material such as dust and sandstones.
Secondly, the utility model replaces solid reinforcement of the prior art with many reinforcing ribs, not only guaranteed the bulk strength of well lid, and make well lid weight alleviate greatly, easy to use, simultaneously, also reduce the material usage of reinforcement, helped to save cost.
Description of drawings:
The embodiment that provides below in conjunction with accompanying drawing is elaborated to the utility model:
The diagrammatic top view of the steel limit steel fibrous concrete manhole cover that provides according to the utility model is provided Fig. 1;
Fig. 2 is along the schematic sectional view of A-A direction among Fig. 1;
