[0026] Reference Figure 1 and Figure 2 This utility model provides a manhole cover frame, which includes slats 100 and reinforcing bars 200.

[0027] The slats 100 are in a ring structure, and there are three slats 100. The three slats 100 are nested in sequence at intervals. The reinforcing bars 200 are in a straight structure, and there are six reinforcing bars 200. Both ends of the reinforcing bars 200 are connected to the inner wall of the outermost slat 100, and the reinforcing bars 200 pass through the other slats 100.

[0028] It is understandable that the reinforcing bar 200 passes through the other slats 100, that is, the reinforcing bar 200 passes through the two inner slats 100, as detailed in the following reference. Figure 1 As shown.

[0029] With the above structure, compared with the traditional manhole cover frame, the manhole cover frame of this application has two inner strips 100, and the reinforcing bars 200 pass through the two inner strips 100. The design of the two inner strips 100 can reduce the probability of the reinforcing bars 200 being bent by the poured concrete, and can optimize the load-bearing support effect of the concrete manhole cover to meet the requirements of some scenarios.

[0030] In this embodiment, both ends of the reinforcing bar 200 are welded to the inner wall of the outermost strip 100; the reinforcing bar 200 and the corresponding positions of the strip 100 through which it passes are welded.

[0031] In some embodiments, the slats 100 are configured as four, etc.

[0032] In some embodiments, the reinforcing bars 200 are configured as eight, etc.

[0033] In this embodiment, refer to Figure 1 and Figure 2 The axes of the three slats 100 are aligned, and the stiffeners 200 are perpendicular to the axes of the slats 100. The six stiffeners 200 are arranged sequentially from top to bottom.

[0034] With the above structure, the six ribs 200 are arranged sequentially from top to bottom, which can improve the structural strength of the manhole cover frame in the axial direction.

[0035] Six 200mm ribs are installed sequentially from top to bottom. For details, please refer to [reference needed]. Figure 2 Half of the six reinforcing ribs 200 are located on the upper side of the slat 100, and the other half are located on the lower side of the slat 100. The three reinforcing ribs 200 on the upper side of the slat 100 abut each other in sequence, and the three reinforcing ribs 200 on the lower side of the slat 100 abut each other in sequence. Among the three reinforcing ribs 200 on the upper side, the abutting points of adjacent reinforcing ribs 200 are welded; among the three reinforcing ribs 200 on the lower side, the abutting points of adjacent reinforcing ribs 200 are welded.

[0036] In this embodiment, refer to Figure 1 The six ribs, each 200mm long, are evenly spaced along their axes.

[0037] With the above structure, the axes of the six ribs 200 and the ring strips 100 are evenly arranged, which can improve the structural strength of the manhole cover frame in the circumferential direction.

[0038] This invention also proposes a concrete manhole cover, which includes the aforementioned manhole cover frame. This structure optimizes the load-bearing support effect to meet the requirements of certain scenarios.

[0039] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
