PROCEDURE FOR THE INSTALLATION OF A MULTI-PATH SECURITY FLOOR FOR CHILDREN'S PARKS AND SAFETY FLOOR OBTAINED FROM

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 procedure for the installation of a multi-layer safety floor for playgrounds and the safety floor obtained therefrom.

The object of the invention is to provide an artificial grass safety floor capable of enabling the grounding of the electrostatic electricity accumulated in the grass, simultaneously allowing to prevent or hinder its theft due to its configuration.

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

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

BACKGROUND OF THE INVENTION

The playgrounds are facilities intended for the use and enjoyment of children, hence the importance in terms of safety that these types of facilities must present in order to minimize the risks of injury in case of broths at different levels, entrapments and accidents due to part of the users who enjoy these leisure facilities.

To assess the safety of any playground, you not only have to consider the configuration and design of the game elements, but also the park floor and,

especially, the play area, since it is the place in the park where children spend more time.

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

In this sense, one of the main security problems presented by the surfaces of the playgrounds of the playgrounds is the poor condition in which they are mainly due to vandal acts. These types of incidents involve serious consequences that endanger the security and physical integrity of the smallest users.

Among the different types of surfaces intended for playgrounds, multi-layer safety floors made of rubber or artificial grass are known.

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 also present as a main advantage over rubber floors, a completely natural environment. However, one of the great disadvantages of artificial turf safety flooring is the accumulation of electrostatic electricity, due to the friction of the users with the surface when they move over it.

The electrostatic electricity produced by friction, which accumulates on the surface of the floors that have synthetic grass, produces electric shocks or unwanted cramps to users who walk on the surface, so these pavements are not used today in the playgrounds for causing great inconvenience.

For all the above, to date, no artificial grass safety floor for playgrounds is known in the state of the art capable of deriving the electrostatic electricity accumulated on its surface to earth and which, in addition, prevents the subtraction of synthetic grass .

DESCRIPTION OF THE INVENTION

Through the multi-layer safety 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-layer safety floor with high performance in terms of safety, since it is capable of absorbing the impact by broth offering a damping that prevents injuries to the Park users and that, in addition, offers a very pleasant and aesthetically attractive game environment, being integrated by artificial grass.

The multilayer safety floor installation procedure for playgrounds is composed of the stages described below:

In the first place, it is necessary to carry out a conditioning of the land. Thus, it is necessary, prior to the installation of the layers that integrate the safety floor, to carry out an adequate preparation and leveling of the surface to clean it, since this will receive the rest of the elements that integrate the safety floor.

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

On the contrary, 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 surface conditioning. Subsequently, the surface is cleaned with

suitable products, preferably hot water with a pressure water cleaning device and degreasing product.

Subsequently, an anchoring means is installed that delimits the installation area of the safety floor and that makes it possible to anchor or fix the following layers that make up the safety floor of the invention. The mentioned anchoring means consists of a curb, concrete perimeter belt or a concrete slab that allows the correct fixation of this to the layers.

Next, an electrically conductive metal element is installed that must necessarily be in contact with the ground. This metal element can be integrated by a metal angle that is installed in inverted mode. This element integrates the grounding and, in addition, allows you to hold all the layers that make up our safety pavement system.

Optionally, the metallic element that conducts electricity can have a C-shaped configuration in order to integrate the ends of the rest of the layers into 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, ensuring that the resulting safety floor is completely draining. The thickness of the elastic base, and the number of layers thereof, will vary depending on the height of the critical broth required in the children's play area. Therefore, the greater the height of the critical broth in the area due to the presence of a children's game of greater height, the greater the thickness of the elastic base must be present to adequately absorb the child's broth.

The elastic base may 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 the critical broth (HIC) required in each area of the park or designated to each area of games security.

In this sense, when the H.I.C. required to be 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 coinciding 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 HIC tall.

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

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

Advantageously, that the metal mesh is in direct contact with the metal element, this being an inverted angle or other electrical conductive material of another configuration that is in contact with the ground, guarantees that the metal mesh is capable of conducting the electrostatic electricity accumulated in the artificial grass layer to the electrical conductor element to be earthed.

In addition, the correct fixation of the metal mesh to the anchoring means will hinder the total or partial subtraction of the artificial grass layer.

Finally, the artificial grass will be unwound and prepared for installation on the metal mesh. Likewise, the synthetic grass will be glued by its internal face, for placement and union with the metal mesh and the geotextile in order to obtain a single element composed of the geotextile - the metal mesh and the grass.

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

After a sufficient period of time for the gluing of the lawn to dry, the artificial grass will be joined with the anchoring means, maintaining

the necessary clearance that facilitates the contraction and dilatation movements that will occur in the grass.

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

Finally, silica sand is deposited on the grass and brushed for proper distribution, and the washing of the grass to remove possible dust from the sand.

In this way, the multi-layer safety floor for playgrounds obtained is constituted by an anchoring means that delimits the area, a conductive metal element in the perimeter of the game area in contact with the ground, a layer of gravel, an elastic base , a geotextile layer, a metal mesh and an upper layer of artificial grass that is visible.

The resulting multilayer safety floor, which has between its layers a metal mesh in contact with a conductive element in contact with the ground, allows the conduction of electrostatic electricity accumulated in the synthetic grass to ground.

Advantageously, the presence of this strategically placed mesh placed under the artificial grass layer makes it difficult to use cutting tools, preventing a smooth tool or surface from being inserted into the grass when quickly cutting a piece of grass. Therefore, the resulting safety floor prevents vandal acts and favors security, preventing downloads to the user who walks on it.

The multilayer safety floor of the invention can be installed in other areas, such as roundabouts, slopes, medium and similar, such as decorative safety pavement against vandal acts.

PREFERRED EMBODIMENT OF THE INVENTION

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

The multilayer safety floor installation procedure for playgrounds will vary depending on the type of installation, with the preferred realization of the installation procedure as described below:

First, the surface (2) on which the different layers that make up the safety floor (1) for playgrounds will be adapted. To do this, we will proceed to mark the area of the playground and to estimate levels by means of measuring devices of the latest technology.

Subsequently, 0.10 m ditches will be made. x 0.15 m that will be concreted defining the anchoring means (not shown in the figures). Subsequently, the metallic conductor element (5) is installed.

Optionally, mortar rules will be created to estimate the level of material filling, as well as a 1.5% slope to facilitate the evacuation of water with contribution of artificial gravel.

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

The angle of inverted metal (5) will preferably be 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 10 cm long expansion screws.

Specifically, the metal element (5) as an inverted angle, is placed with some clearance in order to then be able to place subsequent layers that will be tucked in or fitted under the metal element (5), as can be seen in figure 3.

Then, on the already suitable terrain, a layer of gravel (3) will be deposited, preferably 3/6 caliber gravln and the elastic base (4), whose thicknesses and number of layers will vary depending on the height of the critical broth (HIC ) existing in the security area.

For example, for an H.I.C of 1.30 m. 0.02 m will be placed. of gravel (3) and an elastic layer (4) of 0.02 m thick while when the H.I.C. required to be 1.50 m., 2 centimeters of gravel (3) and two elastic layers (4), one of 0.02 m and the other of 0.010 m thick.

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 metal angle (5) already installed. Subsequently, the metal mesh will be fixed to the metal angle.

Advantageously, that the metal mesh (7) is in contact with the installed metallic conductor 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 grounded.

Finally, we will proceed to prepare artificial grass loaves (8) for placement on the metal mesh (7). Once ready for installation, the internal face of the grass loaves (8) will be glued to join 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 grass (8) is glued to the metal mesh (7) and, that the metal mesh (7) is fixed to the metal angle, it will prevent the total or partial subtraction of the grass.

Once the gluing has dried, a joint closure will be installed throughout the outer perimeter.

Finally, silica sand is deposited on the surface of the artificial grass (8), homogenizing its extension and then the grass is washed. This allows the elimination of dust and the settlement of the silica sand in the artificial grass.

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

In this case, the electrically conductive metal element 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 grounding function.
