Abstract
The utility model relates to a suspended manhole cover which is composed of a board surface and a board bottom. The utility model is characterized in that the board surface is composed of an annular steel board and negative ribs which are arranged in a reticular mode, and two end heads of each of the negative ribs and the outer side edge of the annular steel board are welded and connected. Two steel tube holes are arranged on the board surface, and the board bottom is composed of an annular steel board, an inner annular steel board and main ribs, and the two cross-shaped main ribs are welded on the inner side of the annular steel board. A plurality of star-shaped main ribs connected between the inner side edge of the annular steel board and the inner annular steel board, and the inner annular steel board and the inner side edge of the annular steel board are not in a same plane. The components are integrally cast by cement. The manhole cover not only prevents form stealing, but also has the advantages of high intensity, corrosion resistance, light weight, aging resistance and low cost.
Description
The utility model relates to a kind of inspection shaft lid, exactly is a kind of suspended inspection shaft lid.
The casting iron well lid of the water supply valve well on the urban road, drainage pipe well and telecommunications, electric power, cable television cable inspection-pit is stolen repeatly, not only the safety of pedestrians and vehicles being constituted great prestige assists, and steal the back and mend, mend the vicious circle that steal the back, caused the significant wastage of human and material resources.At the problems referred to above, mainly be to substitute casting iron well lid at present with silicate cement mud product and chemical industry composite product, though can be antitheft, but in use cement products heaviness and rupture strength are low, fragile, though the chemical industry composite product is light than cement products, anti-folding and anti-pressing, but easily aging, application life is short.
The purpose of this utility model provides a kind of not only antitheft, and the intensity height, and is corrosion-resistant, in light weight, anti-aging, the suspended inspection shaft lid that cost is low.
The purpose of this utility model is realized by following technical scheme.
The utility model is formed at the bottom of by plate face and plate, it is characterized in that:
A, plate face are made up of doughnut-shaped steel plate and the negative muscle that is latticed arrangement, the two ends of negative muscle and doughnut-shaped steel plate outside side weld company, and the plate face is provided with two steel pipe holes;
Be made up of doughnut-shaped steel plate, interior doughnut-shaped steel plate and main muscle at the bottom of b, the plate, be welded with two main muscle that are " ten " shape on the doughnut-shaped steel plate inboard, doughnut-shaped steel plate inner side edge and its are not by some between at grade interior doughnut-shaped steel plate
Shape master muscle connects, at the bottom of the plate and in aggregates by cement casting between the plate face.
This inspection shaft lid can with the supporting use of existing cast iron well seat, need not destroy the road surface and change the well toilet and can directly use, when needing to open the inspection shaft lid, only need to insert in the steel pipe hole and stick up out with iron.
The utility model has the advantages that not only can be antitheft, and because of capping has negative muscle, main muscle is arranged at the bottom of the plate, thereby the compressive strength height is in light weight, again because of employing " Sorel " cement casting, thus corrosion-resistant, anti-aging.
Another advantage of the present utility model is reasonable in design, and is with low cost, easy to use.
Fig. 1 is the utility model structural representation.
Fig. 2 is a plate face structure chart.
Fig. 3 is a plate bear building-up composition.
By the following examples, in conjunction with the accompanying drawings, the utility model is done to describe further.
Embodiment 1:
(referring to Fig. 1,2,3) will be the two ends of the negative muscle 4 of latticed arrangement and weld formation plate face 1 skeleton on the outer side edges that is connected in doughnut-shaped steel plate 3.Two of face down bondings in the doughnut-shaped steel plate 3 are the main muscle 7 of " ten " shape, again with doughnut-shaped steel plate 3 inner side edges and its not at grade 6 of interior doughnut-shaped steel plates be with some
Shape master muscle 7 connects into 2 skeletons at the bottom of the plate.Two steel pipes of cloth on the plate face, again with the Sorel cement casting in aggregates the inspection shaft lid, and be furnished with two steel pipe holes (5) on the plate face.
Claims (2)
1, a kind of suspended inspection shaft lid is made up of (2) at the bottom of plate face (1) and the plate, it is characterized in that:
A, plate face (1) are made up of doughnut-shaped steel plate (3) and the negative muscle (4) that is latticed arrangement, the two ends of negative muscle (4) and doughnut-shaped steel plate (3) outside side weld company, and the plate face is provided with two steel pipe holes (5);
(2) are made up of doughnut-shaped steel plate (3), interior doughnut-shaped steel plate (6) and main muscle (7) at the bottom of b, the plate, be welded with two main muscle (7) that are " ten " shape on doughnut-shaped steel plate (3) inboard, doughnut-shaped steel plate (3) inner side edge and its are not by some between at grade interior doughnut-shaped steel plate (6)
Shape master muscle (7) connects, and is in aggregates by cement casting between (2) and plate face (1) at the bottom of the plate.
2, suspended inspection shaft lid according to claim 1, it is characterized in that: it is base material that cement adopts " Sorel " cement.
