Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0012] The ring rib type manhole cover is composed of a cover body 1, an outer ring beam 2, a connecting rib 3, a radial rib 4 and an inner ring beam 5. The outer ring beam 2 , the connecting rib 3 , the radial rib 4 and the inner ring beam 5 are all located on the bottom surface of the cover body 1 and integrated with the cover body 1 . The cover body 1 is a disc body with a circle of downward edges on its circumference. The center of the bottom of the cover body 1 is an annular inner ring beam 5, the inner ring beam 5 is coaxial with the cover body 1 and the outer diameter of the inner ring beam 5 is 1 / 4 of the outer diameter of the cover body 1, and the inside and outside of the inner ring beam 5 The difference in diameter is 5 cm and the thickness is 8 cm. The three radial ribs 4 form an angle of 120° with each other on the plane and connect the e...

Abstract

The invention relates to a municipal facility, in particular to a ring rib type well cover. It consists of a cover body, outer ring beams, connecting ribs, radial ribs and inner ring beams. The center of the bottom of the cover is a ring-shaped inner ring beam. The inner ring beam is coaxial with the cover body and the outer diameter of the inner ring beam is 1 / 4 of the outer diameter of the cover. The three radial ribs form an angle of 120° with each other on the plane. And along the diameter direction of the cover body, the edge of the cover body and the outer circumference of the inner ring beam are connected as a whole. The bottom surface of each radial rib is an inclined plane, and the three connecting ribs form an included angle of 120° with each other on a plane and form an included angle of 60° with adjacent radial ribs. Each connecting rib connects the inner wall of the outer ring beam and the outer periphery of the inner ring beam along the diameter direction of the cover body. The invention greatly improves the pressure resistance of the manhole cover and saves materials at the same time.

Description

technical field [0001] The invention relates to a municipal facility, in particular to a ring rib type well cover. Background technique [0002] The manhole cover on the highway will bear a lot of pressure when the vehicle is rolled over. In order to make the manhole cover have sufficient pressure bearing capacity, the existing manhole cover is made very thick, which is not only inconvenient for transportation and installation, but also very difficult. waste of material. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the invention provides a ring rib type well cover with high compression resistance while saving materials. [0004] The solution to solve the technical problem of the present invention is: the ring rib type well cover is composed of a cover body, an outer ring beam, connecting ribs, radial ribs and an inner ring beam. The outer ring beams, connecting ribs, radial ribs and inner ring beams are all located on the bottom...
