Description

DESCRIPTION

High visibility curb for road safety.

Technical sector

The present invention belongs to the field of "Building Materials", and more specifically to the field of "Precast Concrete"; "Curbs".

The object of the present invention is a color or photoluminescent plastic piece that is added in the manufacturing process to any type of concrete curb, and which geometrically coincides with the shape of the curb face.

Background of the invention

There is no evidence that there are models similar to this invention at present, since to improve the visibility of roundabouts, medium, islets, etc., the bodies responsible for public, local or state roads are used to paint in two colors of the curbs that delimit such elements, which is not comparable neither in result, nor in the improvement of road safety provided by the photoluminescent feature of this invention.

Explanation of the invention.

The inventor of the present application has developed an invention whereby, by adding a photoluminescent colored plastic piece to the traditional precast concrete curbs, it gives them a novel feature (in addition to the traditional serving of separation and finishing to the different types of pavement), which provides a substantial improvement to the road safety conditions of the elements executed with this type of curbs, which results in a lower accident rate and therefore victims.

Among the elements commonly used on public roads, both urban and interurban, are the roundabouts and medium. Its use has been generalized since they are elements that help regulate traffic and moderate speed, as well as serve as a separating element (in the case of mediums) between both directions of movement.

It should be noted that both roundabouts and medium roundabouts are built in such a way that they are finished off at their perimeter through the use of 'concrete curbs'.

We have already indicated the role of regulation and road safety that these elements have, however, especially in the roundabouts located on roads of the secondary network, they do not usually have adequate lighting or visibility which motivates that use is usually used of two-color paints on the curbs that make up its outer perimeter to favor its visibility and therefore increase the road safety of the vehicles that circulate through them.

The present model comes to solve the problem of improving the visibility of the perimeter of roundabouts, medium, islets, bike lane separators, and in general all those elements of public roads that are topped with concrete curbs and that need a Special visibility to improve security. When designing a curb with an exterior component of color or photoluminescent plastic that lines the exposed part of the curb, giving this exceptional visibility in all kinds of conditions and weather.

Brief description of the drawings

Fig. 1 shows the plastic part from its lower face, the one that comes in contact with the curb body and the one with fins intended to serve as an anchor to the concrete that forms the curb.

Fig. 2 is a side view of the piece, in which the external shape of the piece is seen (in this case it coincides with the shape of a lowered curb according to definition UNE-EN 1340), as well as the profile of the concrete anchoring fins.

Fig. 3 is a perspective from the bottom of the piece.

Fig. 4 is a perspective from the top of the piece.

Figs. 5 and 6 are two perspectives from the front and back, respectively.

Fig. 7 is a perspective view of how the piece is in an already finished curb, in which the mortar body (b) and the plastic part coinciding with the curb view area (a) are distinguished.

Preferred Embodiment of the Invention

The precast concrete curbs are manufactured in vibrating presses on which linear molds are placed with the capacity to manufacture between 6 and 12 curbs in each of them. The head of the presses have the shape of the curb according to the different types of them that are included in the regulations in this regard (UNE 127025 and UNE-EN 1340), and the lower part of said molds correspond to the upper part of the curb, that is to say, the face seen is the bottom of the molds or formwork.

The usual manufacturing process consists in pouring a first layer of coarse-grained mortar, and a second thinner mortar spill that provides a better finish to the area seen.

Given the usual manufacturing system just mentioned, it follows that it is extremely easy to place the color or photoluminescent plastic parts at the bottom of the molds, since their dimensions coincide exactly with the outer dimensions of the curbs, or what is the same, with the internal measures of the molds. Additionally, the thin layer is no longer necessary for the area seen.

When placing the plastic parts, there is no need for any complex training of the operators in charge of the process, since in its own way there is only one possible way to properly place the piece, and it is with the face seen resting on the bottom of the mold and the fins of anchorage to the concrete upwards, and on the piece thus placed is where the concrete will be poured.

In this way, with this invention we can transform all types of curbs that until now had the sole mission of serving as a separating element or of closing between different types of floors, in elements that also provide a high improvement of visibility and therefore of Road safety.
