Description

Light high-strength well lid

Technical Field

The utility model relates to a construction engineering field especially relates to a light weight, high strength well lid.

Background

There are many underground pipelines in urban construction, such as sewers, underground gas pipelines, water pipelines, power pipelines, communication pipelines, defense pipelines, etc., every other segment of the pipelines has an outlet to the ground, the segment from the pipeline to the ground is called a manhole, and the manhole is usually flush with the ground, so a manhole cover is needed.

At present, most well lids are made of cement concrete, but the well lids are heavy in weight, inconvenient to install and maintain and easy to damage. To this shortcoming, the utility model provides a glass steel well lid of light weight excel in.

SUMMERY OF THE UTILITY MODEL

In order to solve the above-mentioned drawbacks, an object of the present invention is to provide a light high-strength manhole cover with simple structure, light weight, large load capacity and strong supporting force.

In order to achieve the above object, the utility model discloses a following technical scheme realizes: the utility model provides a light weight, high strength well lid, includes the lid, the lid includes the grid base member, locates the top panel on the grid base member, locates the lower panel under the grid base member, a plurality of notch mouths have been seted up on the lid, it is fixed all through the fine felt of glass and binder bonding between grid base member and top panel and the lower panel.

Furthermore, a reinforcing connecting plate for connecting the upper panel and the lower panel is arranged around the notch.

Further, the upper panel comprises an upper panel main body and a protrusion protruding downwards from the lower side of the upper panel main body, and a groove matched with the protrusion is formed in the upper side of the grating base body.

Further, the lower panel comprises a lower panel main body and a protrusion protruding upwards from the upper side of the lower panel main body, and a groove matched with the protrusion is formed in the lower side of the grating base body.

The utility model has the advantages that: this light weight high strength well lid simple structure, intensity is high, withstand voltage, durable, has prolonged the life of well lid, can save a large amount of steel and expense for the country, reduces municipal construction cost.

Wherein: 1. the upper panel, 2, the grid base body, 3, the lower panel, 4, the notch, 5, the protrusion, 6, the recess.

Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

As shown in fig. 1 and 2, the light high-strength well lid comprises a lid body, wherein the lid body comprises a grid base body 2, an upper panel 1 arranged on the grid base body 2, and a lower panel 3 arranged below the grid base body 2, a plurality of grooving openings 4 are formed in the lid body, and the grid base body 2, the upper panel 1 and the lower panel 3 are bonded and fixed through glass fiber mats and adhesives. And a reinforcing connecting plate for connecting the upper panel 1 and the lower panel 3 is arranged around the notch 4. The upper panel 1 comprises an upper panel 1 main body and a protrusion 5 protruding downwards from the lower side of the upper panel 1 main body, and a groove 6 matched with the protrusion is arranged on the upper side of the grating base body 2. The lower panel 3 comprises a lower panel 3 main body and a bulge 5 which is protruded upwards on the upper side of the lower panel 3 main body, and a groove 6 matched with the bulge is arranged on the lower side of the grating base body 2.

The utility model discloses a grid base member, light in weight, weight are only 1/4 of steel under the equal volume, are 2/3 of aluminium. Meanwhile, the grid matrix is adopted, the strength is high, the strength is ten times of that of rigid PVC, and the strength is far higher than that of aluminum materials, so that the level of common steel is reached. Most well lid body is in the environment of dark humidity, the utility model discloses it is corrosion-resistant, can not go mildy, can not corrode and rust under chemical media's effect, do not need periodic inspection and maintenance, long service life. The installation is convenient, the weight of the grid base plate well lid is greatly reduced, hoisting equipment is not needed during installation, and the installation is economical and convenient. Just the utility model has the characteristics of smoldering and insulating, at installation and use the utility model discloses the time, can not produce the electric spark because of the collision, be applicable to inflammable and explosive environment.
