Abstract
The utility model discloses a kind of plastics well lid, comprise manhole cover body, manhole cover body is provided with cover rim, annular groove is provided with between described manhole cover body and cover rim, the upper surface of manhole cover body is evenly equipped with the first reinforcing rib, and the lower surface of described manhole cover body is evenly equipped with ring stiffener, is evenly equipped with the second reinforcing rib perpendicular to ring stiffener, the center of described manhole cover body is vertically provided with the 3rd reinforcing rib, and whole manhole cover body is by mold disposal molding.Compared with prior art, the utility model manhole cover body inside adds the reinforcing ribs such as perpendicular, ring, makes it disperse stressed, thus reach the effect of intensity increase, and manufacture craft is simple, mold disposal molding, shortened process be that the safety factor of plastics well lid significantly promotes.
Description
Technical field
The utility model relates to a kind of manhole cover structure, particularly the plastics well lid that significantly strengthens of a kind of safety factor and well lid intensity.
Background technology
Existing plastics well lid is mostly due to the restriction of material, cause its load-carrying ability not strong, needs and reinforcing bar mix the weight of material casting or increase self makes its intensity increase, but mixed casting result in the numerous and diverse at substantial manpower and materials of operation, weightening finish not only cost increase, also can cause carrying and assembling time encounter difficulties.
Summary of the invention
The purpose of this utility model to provide the plastics well lid that a kind of intensity is large, safety factor is high.
For achieving the above object, the utility model is implemented according to following technical scheme:
A kind of plastics well lid, comprise manhole cover body, manhole cover body is provided with cover rim, annular groove is provided with between described manhole cover body and cover rim, the upper surface of manhole cover body is evenly equipped with the first reinforcing rib, described manhole cover body lower surface be evenly equipped with ring stiffener, be evenly equipped with the second reinforcing rib perpendicular to ring stiffener, the center of described manhole cover body is vertically provided with the 3rd reinforcing rib, and whole manhole cover body is by mold disposal molding.
As preferred version of the present utility model, the first described reinforcing rib is block.
Compared with prior art, the utility model manhole cover body inside adds the reinforcing ribs such as perpendicular, ring, makes it disperse stressed, thus reach the effect of intensity increase, and manufacture craft is simple, mold disposal molding, shortened process be that the safety factor of plastics well lid significantly promotes.
