Description

A kind of well lid structure

Technical field

The utility model relates to a kind of well lid structure, is a kind of well lid of rib type structure specifically.

Background technology

Existing well lid manufactured materials is generally concrete manhole cover or ductile iron QT500-7 is main, concrete manhole cover generally is the well lid matrix that steel bar framework and concrete are made, when making well lid, place reinforcing bar or add a certain amount of steel fibre, steel bar framework is arranged in the matrix, also is evenly distributed with rigid fiber and flexible fiber in matrix.With ductile iron QT500-7 is the well lid of main material, external form mainly contains circle, square, rectangle etc., on project organization, require to have bigger dynamic and static bearing pressure, a lot of for this reason manufacturing enterprises are for improving the bearing strength of well lid, or with the well lid thickening or at the abundant rib structure of well lid bottom adding, though strengthened the supporting capacity of well lid thus, caused the well lid cost of manufacture to gain in weight thus and laid particular stress on, be difficult to the result of use that reaches flexible.

China's utility application numbers 200820117349.3 discloses a kind of new pattern manhole cover, as depicted in figs. 1 and 2, the well lid matrix 1 that the concrete 5 that framework 4 that this well lid is made by reinforcing bar and strength mark are C30～C60 is made is evenly distributed with rigid fiber 2 in this matrix 1 and flexible fiber 3. steel bar frameworks 4 are formed by straight reinforcing bar 6, bent-up bar 8 and steel plate ring 7 Combination Welding.Adopt the composite fibre structure of rigid fiber 2 in conjunction with flexible fiber 3, when this well lid of preparation, at first steel bar framework 4 need be put and be fixed in the mould, add to rigid fiber 2 and flexible fiber 3 in the concrete again and stir, with also vibration compacting moulding in the concrete pouring progressive die tool that stirs, promptly prepare this well lid through the maintenance demoulding more then.Adopt this preparation well lid mode, preparation time is long, and complicated operation, be unfavorable for that large tracts of land comes into operation, steel fiber and concrete modulus of elasticity are all bigger simultaneously, and the well lid of making ftractures easily, and poor performance such as shock resistance, application life is also lower, and the weight of this kind well lid is heavier, is unfavorable for carrying.

The utility model content

In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of novel simple and direct ribs type structure, improves the dynamic and static carrying of well lid by rib type structure and can press, and reaches the result of use of safe and applicable, reduces the cost of manufacture of well lid simultaneously.

The technical solution of the utility model is: a kind of well lid structure, comprise edge, well lid outer ring, main ribs, one end of described a plurality of main ribs and well lid outer ring are along being connected, the other end of described a plurality of main ribs and corresponding corresponding connection of a plurality of auxilliary ribs, described a plurality of auxilliary ribs are connected with corresponding a plurality of interior ribs.

A kind of well lid structure described in the utility model, wherein, described well lid outer ring is 20mm～50mm along wall thickness.

A kind of well lid structure described in the utility model, wherein, described main ribs is six.

A kind of well lid structure described in the utility model, wherein, described six main ribs distribute along being six five equilibriums around the well lid outer ring.

A kind of well lid structure described in the utility model, wherein, described auxilliary ribs is six.

A kind of well lid structure described in the utility model, wherein, described six auxilliary ribs and corresponding main ribs are six five equilibriums and intersect and dock.

A kind of well lid structure described in the utility model, wherein, described auxilliary ribs is connected with interior ribs.

A kind of well lid structure described in the utility model, wherein, described interior ribs one end and the positive hexagon of auxilliary ribs are six five equilibrium vertical lines and intersect, and the other end of described interior ribs docks just hexagonal shape in surrounding mutually.

Beneficial effect described in the utility model is: this simple and direct ribs type structure of this well lid structure, the supporting capacity height of well lid, and rib type structure has alleviated the weight of well lid structure, well lid is simple in structure, the cost of making is low, the suitable production in enormous quantities in enormous quantities, be widely used in load-bearing such as power pipeline well, street lamp well, fire-fighting well, various valve wells.

Description of drawings

Describe the utility model in detail below in conjunction with the drawings and specific embodiments;

Fig. 1 is the cross-sectional view of new pattern manhole cover.

Fig. 2 is the attached view of Fig. 1.

Fig. 3 is the vertical view of a kind of well lid structure of the utility model.
