PROCEDURE FOR THE INSTALLATION OF A SAFETY FLOOR

MULTICAPA FOR PARKS FOR CHILDREN AND SOIL OF SECURITY OBTAINED TO

START FROM THE SAME

D E S C R I P C I O N

OBJECT OF THE INVENTION The present invention relates to a method for installing a multilayer security floor for playgrounds and the security floor obtained therefrom.

The object of the invention is to provide an artificial turf security floor capable of enabling the derivation to ground of the electrostatic electricity accumulated in the lawn, simultaneously making it possible to prevent or hinder the theft thereof due to its configuration.

The safety floor for playgrounds is composed of several layers, among which are a layer of gravel, an elastic base, a layer of geotextile, and a metal mesh on which is deposited and a layer of artificial turf.

Advantageously, the presence of the metal mesh combined with the rest of the layers enables the aforementioned safety and anti-vandalism functions.

BACKGROUND OF THE INVENTION

Playgrounds are facilities for the use and enjoyment of children, hence the importance in terms of safety that this type of facility must present in order to minimize the risk of injury in the event of falls at different levels, entrapments and accidents. part of the users who enjoy these leisure facilities.

To assess the safety of any playground, not only the configuration and design of the game elements, but also the park floor and, especially, the play area, since it is the place of the park where the children spend the most time.

One of the safety measures aimed at reducing the injuries caused by falls at different levels, is the installation of a safety floor capable of absorbing and / or cushioning the falls that occur in this type of facilities, the main cause of injuries in the Children under 14 years old.

In this sense, one of the main security problems that present the surfaces of the play areas of playgrounds is the poor state in which they are due, mainly, to vandalism. This type of incivility acts have serious consequences that endanger the security and physical integrity of the smallest users. Among the different types of surfaces intended for playgrounds are known multilayer security floors formed by rubber or artificial turf.

On the one hand, rubber safety floors are mainly presented in two types, tile flooring or continuous rubber flooring, both of which are capable of absorbing impacts.

On the other hand, artificial turf safety pavements are not only capable of absorbing impacts, but have as a main advantage in front of rubber floors, a completely natural setting of the environment. However, one of the great disadvantages of artificial turf security pavements is to accumulate electrostatic electricity, due to the friction of users with the surface when they move on it.

Electrostatic electricity produced by friction, which accumulates on the surface of soils that have synthetic turf, produces electric shocks or unwanted cramps to users who walk on the surface, so these pavements are not used today in the playgrounds cause great inconvenience. For all of the above, to date there is no known artificial safety floor for playgrounds capable of deriving the electrostatic electricity accumulated on its surface to earth, which also prevents the removal of synthetic turf. .

DESCRIPTION OF THE INVENTION

Through the multi-layered security floor for playgrounds of the present invention, the problem described above is solved.

Thus, the installation procedure of the invention is integrated by the placement of several layers, resulting in a multi-layered safety floor with high performance in terms of safety, since it is capable of absorbing the impact by falling offering a cushion that prevents injuries to the users of the park and, moreover, offers a very pleasant and aesthetically appealing game medium, as it is composed of artificial turf.

The installation procedure of multi-layered security floor for playgrounds is integrated by the stages described below:

In the first place, it is necessary to carry out a ground conditioning. Thus, it is necessary, prior to the installation of the layers that make up the security floor, to carry out an adequate preparation and leveling of the surface to clean it up, given that it will receive the rest of the elements that make up the security floor.

In case of carrying out the installation procedure on a rubber tile floor already installed, it will be necessary to remove them during the surface conditioning stage.

On the other hand, when the installation procedure of the invention is carried out on a continuous rubber floor, it will be advisable to fill the cavities with SBR rubber during the conditioning of the surface. Subsequently, the surface is cleaned with suitable products, preferably hot water with a device for cleaning water under pressure and degreasing product.

Next, an anchoring means is installed that delimits the installation area of the security floor and that makes possible the anchoring or fixing of the following layers that integrate the security floor of the invention. The aforementioned anchoring means consists of a curb, concrete perimeter belt or a concrete slab that allows the correct fixing of this to the layers. Next, an electrically conductive metallic element is installed that must necessarily be in contact with the ground. This metallic element can be integrated by a metallic angle that is installed in inverted mode. This element integrates the ground connection and, in addition, allows to hold all the layers that make up our security pavement system.

Optionally, the metallic conductor element of electricity can have a C-shaped configuration in order to integrate the ends of the rest of the layers inside it. Next, the area delimited in the previous stage is filled with gravel.

Next, at least one elastic base is placed on the gravel, which will favor the passage of water through the whole, guaranteeing that the resulting safety floor will be totally draining. The thickness of the elastic base, and the number of layers of it, will vary depending on the height of critical fall required in the playground. Therefore, the higher the height of critical fall in the area due to the presence of a child's game of greater height, the thicker the elastic base must have to adequately absorb the child's fall. The elastic base can have a homogeneous thickness along the entire surface of the playground or on the contrary have a heterogeneous thickness distribution depending on the height of critical fall (HIC) required in each area of the park or designated to each area security of the games. In this sense, when the required HIC is very high in the area of security of the game, an elastic layer of greater thickness than the rest of the surface of the park is installed, either integrating two layers, where the first one has a thickness coincident with the thickness of the elastic layer of the rest of the park or placing a single layer of greater thickness in the area that requires a high HIC.

Next, a geotextile layer that separates and protects the elastic base and the lower gravel layer of the rest of the layers to be installed is placed on the elastic base.

Next, at least one metal mesh is placed which will be fixed to the anchoring means, coming into direct contact with the previously installed conductive metallic element.

Advantageously, that the metal mesh is in direct contact with the metal element, this being an inverted angle or another electrically conductive material of another configuration that is in contact with the ground, ensures that the metallic mesh is capable of conducting the electrostatic electricity accumulated in the layer of artificial turf up to the electrical conductor element to derive it to earth. In addition, the correct fixing of the metal mesh to the anchoring means will hinder the total or partial subtraction of the artificial turf layer.

Finally, the artificial turf will be unrolled and prepared for its installation on the metal mesh. Likewise, it will proceed to the gluing of the synthetic turf by its internal face, for its placement and union with the metallic mesh and the geotextile in order to obtain a single element integrated by the geotextile - the metal mesh and the grass.

Advantageously, the integration of these three layers in a single element will make it possible to replace this assembly in an easy and fast way, when the time comes, keeping the sub-base of the installation unsubstituted, since this maintains its properties for a longer period of time .

After a sufficient period of time for the gluing of the lawn has dried, proceed to the union of artificial turf with the anchoring means, maintaining the necessary slack that facilitates the movements of contraction and dilation that will occur in the lawn.

Optionally, the lawn presents conductive fibers in its framework to facilitate the conduction of electrostatic electricity that accumulates on its surface.

Finally, silica sand is deposited on the lawn and brushed for proper distribution, and to wash the grass to remove any dust from the sand. In this way, the multi-layered security floor for playgrounds obtained is constituted by an anchoring means that delimits the area, a conductive metallic element in the perimeter of the area of the game in contact with the ground, a layer of gravel, an elastic base , a geotextile layer, a metal mesh and a top layer of artificial turf that is visible.

The resulting multi-layered security floor, which has a metallic mesh between its layers in contact with a conductive element in contact with the ground, makes it possible to ground the electrostatic electricity accumulated in the synthetic turf. Advantageously, the presence of this strategically placed mesh placed under the layer of artificial turf makes it difficult to use cutting tools, preventing that when inserting a cutting tool in the lawn find a support or smooth surface on which to cut a piece quickly of grass. Therefore, the resulting safety floor prevents vandalism and promotes safety, preventing discharges to the user who walks on it.

The multilayer security floor of the invention can be installed in other areas, such as roundabouts, slopes, medians and the like, as a decorative security pavement against vandalism. DESCRIPTION OF THE DRAWINGS

PREFERRED EMBODIMENT OF THE INVENTION

Figures 1, 2 and 3 show the resulting floor (1) obtained when performing the installation procedure that is detailed below.

The procedure for installing the multi-layered security floor for playgrounds will vary depending on the type of installation, the preferred embodiment of the installation procedure being that described below: First, the surface (2) will be adapted which will be installed the different layers that make up the security floor (1) for playgrounds. To do this, we will proceed to mark the area of the playground and the estimation of levels using state-of-the-art measuring devices. Subsequently ditches of 0.10 m will be made. x 0.15 m that will be concreted defining the anchoring means (not shown in the figures). Subsequently, the conductive metallic element (5) is installed. Optionally, rules will be created with mortar to estimate the level of filling of materials, as well as a slope of 1, 5% to facilitate the evacuation of water with contribution of artificial gravel.

The placement of an angle of inverted metal (5), as a metallic conductor element, allows to secure and protect all the layers to be installed. This conductive metallic element (5) can be seen in figure 3.

The inverted metal angle (5) will preferably be made of iron, but it can be obtained in any material capable of conducting electricity and will have dimensions that will vary depending on the height of the elastic base to be protected.

The angle (5) will be fixed to the ground on the concrete belt, preferably by means of fixing elements such as expansion screws of 10 cm in length. Then, on the land already suitable, a layer of gravel (3), preferably gravín 3/6 caliber and the elastic base (4), whose thicknesses and number of layers will vary depending on the height of critical fall (HIC) will be deposited. ) existing in the security area. For example, for an HIC of 1.30 m. 0.02 m will be placed. of gravel (3) and an elastic layer (4) of 0.02 m thickness, while when the required HIC is 1.50 m, 2 centimeters of gravel (3) and two elastic layers (4) will be placed , one of 0.02 m and another of 0.010 m of thickness. Next, a layer of geotextile (6), preferably 200 gr / m, will be placed on the elastic base (4) to protect and separate the already installed layers from the rest of the layers to be installed, and thus protect them from the movements that will occur. in the synthetic grass layer (8). Subsequently, the metal mesh (7) will be placed on the geotextile layer (6) causing it to be in contact with the metallic angle (5) already installed. Subsequently, the metal mesh will be fixed to the metallic angle. Advantageously, that the metal mesh (7) is in contact with the installed metallic element (5), which, in turn, is in contact with the ground, makes it possible with total guarantee that the electrostatic electricity produced by friction in the layer of Synthetic grass can be derived to earth. Finally, it will proceed to prepare the artificial turf cloths (8) for its placement on the metal mesh (7). Once it is ready for installation, the internal face of the turf panels (8) will be glued to be joined with the metal mesh (7) and the geotextile layer (6), so that they are integrated as a single element and facilitate its replacement.

Advantageously, that the artificial turf (8) is glued to the metal mesh (7) and, that the metal mesh (7) is fixed to the metallic angle, will prevent the total or partial subtraction of the turf. Once the gluing has dried, the installation will proceed to a joint closure around the outside perimeter.

Finally, silica sand is deposited on the surface of the artificial grass (8), homogenizing its spread and then washing the grass. This allows the removal of dust and the settlement of silica sand on artificial turf.

In a second variant of the described installation procedure, the installation of the security floor is carried out on a flat concrete surface.

In this case, the metallic conductor element of electricity to be installed will be metal plates that will be fixed to the concrete layer and will be in contact with the ground to fulfill its function of grounding.
