Description

Novel inspection well cover

Technical Field

The invention relates to the technical field of building facilities, in particular to a novel inspection well cover.

Background

The inspection well cover is the most common and necessary facility in the fields of municipal construction and the like. Common inspection shaft lid all includes carriage and apron. The area of apron is generally not more than this braced frame's internal area, and the inner wall of braced frame is the conical body that the diameter is great, the diameter is less below for above-mentioned diameter usually to apron card is inside the braced frame when using, makes the apron extremely stable and can not drop. The defects are as follows: the cover plate is easy to damage after being pressed, and particularly the edge part is easy to crush, so that the service life of the cover plate is short; meanwhile, the inspection well cover is usually prepared by adopting a casting process or a composite material, so that the cost is relatively high, certain pollution is caused to the environment during production, and the inspection well cover is difficult to adapt to the current strict environmental protection requirement.

Detailed Description

Examples, see fig. 1-4: a novel inspection well cover comprises a support frame 10 and a cover plate 20. Generally, the support frame 10 and the cover plate 20 may be circular or square, with circular being the most common.

Further speaking:

the supporting frame 10 includes a horizontal frame 11 located at the lower portion and a vertical frame 12 located at the upper portion, the lower side of the vertical frame 12 is vertically fixed on the horizontal frame 11 to make the cross section of the supporting frame 10 in an inverted "T" shape, and the horizontal frame 11 is divided by the lower side of the vertical frame 12 into an inner supporting edge 111 located at the inner side of the vertical frame 12 and an outer supporting edge 112 located at the outer side of the vertical frame 12. That is, the downward projection of the vertical frame 12 falls within the downward projection of the horizontal frame 11. Obviously, the horizontal frame 11 and the vertical frame 12 are both closed square frame type or circular.

The cover plate 20 comprises a horizontal plate 21.

More specifically:

when the cover plate 20 is covered on the supporting frame 10, the downward projected outer edge of the horizontal plate 21 falls on the downward projected outer edge of the vertical frame 12, or the downward projected outer edge of the horizontal plate 21 coincides with the downward projected outer edge of the vertical frame 12. That is, the outer edge of the horizontal plate 21 is flush with the outer edge of the vertical frame 12. This is, of course, under acceptable error conditions.

When the supporting frame 10 and the cover plate 20 are both circular, the outer diameter of the horizontal plate 21 is D2, the inner diameter of the horizontal frame 11 is L1, the inner diameter of the vertical frame 12 is L2, the thickness is δ, and the outer diameter of the horizontal frame 11 is L3, then L1 < L2, L2+2 δ < L3, and L2+2 δ is not more than D2, preferably L2+2 δ is D2. At this time, the horizontal frame 11 and the vertical frame 12 are closed circles.

Thus, because the lower surface of the horizontal plate 21 is inevitably supported on the upper side of the vertical frame 12 when in use, when a large pressure is applied, the pressure is directly transmitted to the ground supporting the supporting frame 10, thereby reducing the probability of damage to the cover plate 20 and ensuring the safety of the manhole cover in use.

Optimizing:

the cover plate 20 further includes a frame-shaped inner frame 22 whose upper side is fixed to the lower surface of the horizontal plate 21. Obviously, the inner frame 22 is of a closed square or circular shape. There is a non-zero spacing between the outer edge of the horizontal plate 21 and the circumferential outer surface of the inner frame 22 so that the portion of the edge of the horizontal plate 21 outside the circumferential outer surface of the inner frame 22 is formed with an upper support rim 211. And, when the cover plate 20 is covered on the support frame 10, the upper support edge 211 is supported on the upper side of the vertical frame 12, and the inner frame 22 is located inside the vertical frame 12. That is, the inner frame 22 limits the cover plate 20 from excessively moving relative to the support frame 10. At this time, the height of the vertical frame 12 is set to H1, and the height of the inner frame 22 is set to H2, H1 is not more than H2.

When the cover plate 20 is covered on the support frame 10, the lower side of the inner frame 22 is supported on the inner support rim 111. Obviously, when the support frame 10 and the cover plate 20 are both circular, the inner frame 22 must be a closed circle. If the inner frame 22 has an inner diameter D1 and a wall thickness γ, L1 is not less than D1, D1+2 γ is not less than L2, preferably L1 < D1, and D1+2 γ < L2. At this time, H1 ═ H2.

And (4) continuing optimization:

a triangular reinforcing plate 13 is fixed between the circumferential outer surface of the vertical frame 12 and the outer support rim 112. The stiffening webs 13 necessarily lie in vertical planes.

As shown in fig. 5, the lower surface of the horizontal plate 21 is provided with reinforcing ribs 23, and the reinforcing ribs 23 may be distributed in a spider-web shape. Obviously, the downward projections of the ribs 23 are necessarily all within the downward projection range of the inner frame 22.

In addition:

the left side of the support frame 10 is hinged to the left side of the cover plate 20, and a locking mechanism can be arranged between the right side of the support frame 10 and the right side of the cover plate 20.

Referring to fig. 6, when the vertical frame 12 and the inner frame 22 are both circular, the inner side of the vertical frame 12 is provided with a protrusion 121, the outer side of the inner frame 22 is provided with a horizontal protrusion 221, and the protrusion 121 and the protrusion 221 are matched. The protruding strip 221 may also be a 7-shaped slot. Thus, after the inner frame 22 is in place, the cover plate 20 can be slightly rotated to position the protrusions 121 above the corresponding ribs 221, or the protrusions 121 enter the transverse grooves of the corresponding 7-shaped slots, so that the cover plate 20 can be automatically locked.

The supporting frame 10 and the cover plate 20 are made of steel materials through welding. Therefore, the preparation difficulty is further reduced, processes such as casting and the like are not required, and the requirements of the current strict environmental protection policy are met. Of course, the surfaces of the support frame 10 and the cover plate 20 are necessarily provided with the anti-corrosion layer, and the support frame 10 and the cover plate 20 are not limited to steel materials.

The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
