Benefits of technology
The cover in this invention is made with lighter materials, which makes it stronger but also lighter than conventional covers. This makes it easier to handle and transport.
Problems solved by technology
One problem associated with manhole covers is that they are often at risk of theft, given that they are made of cast metal and able to be sold by weight, since they can be recycled as scrap metal.
However, said manhole covers are more expensive than common cast metal manhole covers.
Another problem associated with manhole covers is that over time they can end up moving into the housing thereof, which causes load noises and bangs, resulting in annoyances to neighbors who live in the area of said cover.

Embodiment Construction
[0008]The cover of the present invention resolves the aforementioned drawbacks and has other advantages which are described below.
[0009]The cover for use on public roads according to the present invention comprises at least an outer body made of a plastic material which houses at least a reinforcement, said reinforcement able to be metal or ceramic.
[0010]Advantageously, said reinforcement can be in the form of bars, wires, threads, grilles, profiles, sheet metal, cables and / or cords, and for example, said reinforcement is made of steel or aluminum, or alumina, silicon carbide, silicon nitrate, zirconia, sialon or fiberglass, carbon fiber or aramid fiber, although it could be any suitable material that has a sufficient resistance.
[0011]According to two alternative embodiments, said outer body can define a substantially flat continuous upper and lower surface.
[0012]Advantageously, the cover for use on public roads according to the present invention can comprise a housing, for example ...

Abstract
The invention relates to a cover for use on public roads, comprising an outer body (2) that houses at least one reinforcement (1). Preferably, said outer body (1) is made of a plastic material, e.g. injected plastic material, and said at least one reinforcement (1) is connected by means of said outer body (2) to form a single piece.The cover according to the invention is lighter than that conventional covers, given that it is made with less metal and with lighter materials. Moreover, the cover cannot be easily recycled and hence is not at risk of theft.
Description
[0001]The present invention relates to a cover for use on public roads, which must support the weight of people and vehicles that pass over the same.BACKGROUND OF THE INVENTION[0002]Covers for use on public roads, for example manhole covers, are widely known by the general public, normally located on the ground on streets of any city, and have the function of covering access to the public sewers, as well as access to utility tunnels, etc.[0003]Said covers are typically made of metal materials, the most common of which are covers made of cast metal (iron with greater than 2% carbon).[0004]One problem associated with manhole covers is that they are often at risk of theft, given that they are made of cast metal and able to be sold by weight, since they can be recycled as scrap metal.[0005]Currently there are other types of manhole covers, in addition to ones made by cast metal, the characteristics of which make them so they are not at risk of theft (either due to the low weight thereof...
