Description

La présente invention concerne une dalle antichocs modulaire notamment pour salles de sports, aires de jeux, réceptions d'aires de saints, etc ... pouvant être disposée horizontalement pour constituer par assemblage un revêtement de sol, mais aussi dans certains cas particuliers, contre des parois verticales.The present invention relates to a modular shockproof slab in particular for sports halls, play areas, reception areas for saints, etc. which can be arranged horizontally to constitute by assembly a floor covering, but also in certain specific cases, against vertical walls.

Il est connu des dalles de ce type, constituées par des modules en caoutchouc permettant d'amortir les chocs et d'éviter les détériorations provoquées par la chute des pièces de métal ou de toute autre matière. Ces modules sont constitués par une sous-couche amortissante par exemple en caoutchouc mousse en contact avec le sol et une couche de choc renforcée résistant aux fortes pressions et aux cisaillements importants, survenant lors de la chute de pièces lourdes.Tiles of this type are known, constituted by rubber modules making it possible to absorb shocks and to avoid deterioration caused by falling pieces of metal or any other material. These modules are made up of a shock-absorbing sub-layer, for example of foam rubber in contact with the ground, and a reinforced shock layer resistant to high pressures and significant shearing, occurring during the fall of heavy parts.

Ces revêtements de sol constitués par ce type de dalles ne sont pas adaptés aux applications précitées car la couche de choc est trop dure en cas de chute d'une personne ou d'un enfant, soit accidentelle, soit au cours d'une activité sportive. De plus, ces dalles sont simplement posées au sol et retenues par les murs latéraux de la salle ou encore elles peuvent être fixées par des vis dans des trous chevillés pratiqués dans le sol, mais cela implique une manutention et une mise en oeuvre longue et coûteuse et une détérioration du sol. Dans certains cas d'utilisation temporaire d'une salle à cet usage, cela n'est pas admissible.These floor coverings formed by this type of tiles are not suitable for the aforementioned applications because the shock layer is too hard in the event of a fall of a person or a child, either accidentally or during a sports activity. . In addition, these tiles are simply placed on the floor and retained by the side walls of the room or they can be fixed by screws in holes pegs practiced in the ground, but this involves handling and a long and costly implementation and deterioration of the ground. In certain cases of temporary use of a room for this use, this is not admissible.

Bien entendu, on pourrait songer à utiliser des dalles ou des tapis en caoutchouc mousse souples et sans couche de choc ou tout au moins, moins dure, mais on se heurte alors à un autre problème car il n'est pas aisé de marcher ou de courir sur une surface trop souple.Of course, one could consider using flexible foam rubber slabs or mats without a shock layer or at least less hard, but then we run into another problem because it is not easy to walk or run on a too soft surface.

On voit bien que la difficulté réside dans le compromis à trouver entre un revêtement de sol ayant à la fois des qualités d'amortissement suffisante en cas d'impact causé par une chute ou une réception consécutive à un saut, et des qualités de rigidité offrant un confort de marche, normal lors de déplacement sur un tel revêtement de sol, par un individu au pas.It is clear that the difficulty lies in the compromise to be found between a floor covering having both sufficient damping qualities in the event of an impact caused by a fall or a reception following a jump, and stiffness qualities offering walking comfort, normal when moving on such a floor covering, by an individual walking.

Le but de la présente invention est bien de remédier à ces inconvénients et concerne à cet effet une dalle du type précité qui selon l'invention est constituée d'une structure alvéolaire semi-rigide composée de nervures verticales reliées entre elles à leur partie supérieure par une toile souple horizontale et aptes à subir une déformation relative en compression, en fonction d'une charge verticale.The purpose of the present invention is to remedy these drawbacks and for this purpose relates to a slab of the aforementioned type which according to the invention consists of a semi-rigid honeycomb structure composed of vertical ribs connected to each other at their upper part by a horizontal flexible fabric capable of undergoing a relative deformation in compression, as a function of a vertical load.

La déformation relative en compression des nervures verticales est obtenue par compromis entre la hauteur de la nervure, sa largeur, son épaisseur et la nature du matériau.The relative compression deformation of the vertical ribs is obtained by compromise between the height of the rib, its width, its thickness and the nature of the material.

Avantageusement, la toile souple horizontale est réalisée en retrait de la partie supérieure des nervures et se subdivise en autant de parties de toile que d'alvéoles qu'elles obturent de manière à laisser subsister une hauteur de nervures apparente, déterminée par le plan supérieur de la partie de toile et le sommet de ladite nervure pour constituer une surface antidérapante.Advantageously, the horizontal flexible fabric is produced set back from the upper part of the ribs and is subdivided into as many parts of fabric as there are cells which they close so as to leave an apparent height of ribs, determined by the upper plane of the canvas part and the top of said rib to form a non-slip surface.

De préférence, les sommets apparents des nervures délimitent avec la toile des logements alvéolaires au fond desquels est réalisé au moins un plot antidérapant laissant subsister dans ledit logement alvéolaire au moins une rainure d'écoulement d'un liquide.Preferably, the visible tops of the ribs delimit with the fabric honeycomb housings at the bottom of which is produced at least one non-slip stud leaving in said honeycomb housing at least one groove for the flow of a liquid.

Selon une caractéristique de l'invention, la structure alvéolaire formant ladite dalle est obtenue de manière monobloc au cours d'une même opération de moulage d'un élastomère.According to a characteristic of the invention, the honeycomb structure forming said slab is obtained in a single piece during the same operation of molding an elastomer.

De telles dalles sont reliées entre elles, pour constituer un revêtement de sol, par un sytème d'amarrage.Such slabs are connected together, to form a floor covering, by a mooring system.

Préférentiellement, un tel système d'amarrage pour la mise en oeuvre des dalles selon l'invention est constitué par quatre pieds de forme et de dimensions correspondant à quatre alvéoles d'angle de quatre dalles à structure alvéolaire à réunir, dans lesquelles ils s'emboîtent au montage, lesdits pieds étant reliés entre eux par des ponts.Preferably, such a mooring system for the implementation of the slabs according to the invention consists of four feet of shape and dimensions corresponding to four corner cells of four slabs of cellular structure to be joined, in which they are fit together during assembly, said feet being interconnected by bridges.

Un tel système est avantageusmenet réalisé par moulage monobloc d'un élastomère de mêmes caractéristiques mécaniques que les dalles à réunir.Such a system is advantageously carried out by monoblock molding of an elastomer having the same mechanical characteristics as the slabs to be joined.

D'autres caractéristiques ressortiront de la description qui va suivre en regard des dessins annexés sur lesquels :

  • la figure 1 représente vue en plan une portion de dalle antichocs selon l'invention ;
  • la figure 2 est une vue en perspective selon une coupe selon la ligne I/I' de la figure 1 ;
  • la figure 3 est une vue en plan d'un système d'amarrage de dalles selon l'invention, et
  • la figure 4 est une vue en perspective selon une coupe selon la ligne III/III' de la figure 3.
Other characteristics will emerge from the description which follows with reference to the appended drawings in which:
  • FIG. 1 shows a plan view of a portion of an impact-resistant slab according to the invention;
  • Figure 2 is a perspective view in section along the line I / I 'of Figure 1;
  • FIG. 3 is a plan view of a slab mooring system according to the invention, and
  • FIG. 4 is a perspective view in section along the line III / III 'in FIG. 3.

La dalle 1 partiellement représentée sur les figures 1 et 2 est constituée d'une structure alvéolaire semi-rigide composée de nervures verticales 2, formant des croisillons perpendiculaires, et reliées entre elles par une toile souple horizontale 3 à leur partie supérieure 2a, au cours d'une même opération de moulage.The slab 1 partially shown in Figures 1 and 2 consists of a semi-rigid honeycomb structure composed of vertical ribs 2, forming perpendicular crosspieces, and connected together by a horizontal flexible canvas 3 at their upper part 2a, during of the same molding operation.

Une telle structure est apte à subir une déformation relative en compression, en fonction d'une charge verticale F, qui est obtenue par compromis entre la hauteur h de la nervure 2, sa largeur 1, son épaisseur e et la nature du matériau utilisé.Such a structure is capable of undergoing a relative deformation in compression, as a function of a vertical load F, which is obtained by compromise between the height h of the rib 2, its width 1, its thickness e and the nature of the material used.

Il a été constaté qu'avec des nervures 2 ayant une hauteur h = 35 mm, une largeur l = 20 mm, une épaisseur e = 2 mm et un matériau tel qu'un élastomère, des résultats satisfaisants ont été obtenus. Ainsi, une structure constituée par un plan souple étayé verticalement par des parois verticales, en l'occurrence les nervures 2 aptes à subir un flambage en fonction d'une charge verticale F, permet une absorption d'énergie égale ou supérieure à 30 joules sous un impact de 500 kg pour 10 cm². Une telle absorption correspond à la chute d'un homme tombant d'une hauteur de 2,50 m sur ses deux talons. Il est évident que si des chutes plus importantes étaient prévues, il serait donné d'autres dimensions à la structure alvéolaire.It has been observed that with ribs 2 having a height h = 35 mm, a width l = 20 mm, a thickness e = 2 mm and a material such as an elastomer, satisfactory results have been obtained. Thus, a structure constituted by a flexible plane supported vertically by vertical walls, in this case the ribs 2 capable of undergoing buckling according to a vertical load F, allows an energy absorption equal to or greater than 30 joules under an impact of 500 kg for 10 cm². Such absorption corresponds to the fall of a man falling from a height of 2.50 m on his two heels. It is obvious that if larger falls were planned, other dimensions would be given to the honeycomb structure.

Selon l'exemple de réalisation représenté sur les figures, la toile souple 3 est réalisée en retrait de la partie supérieure 4 des nervures 2 et se subdivise en autant de parties de toile 3 que d'alvéoles. Les parties de toile 3 obturent ainsi ces dernières de manière à laisser subsister une hauteur h₁ de nervure 2 apparente, déterminée par le plan supérieur 3a et le sommet 4 de ladite nervure 2 pour constituer avantageusement une surface antidérapante.According to the exemplary embodiment shown in the figures, the flexible fabric 3 is produced set back from the upper part 4 of the ribs 2 and is subdivided into as many parts of fabric 3 as there are cells. The canvas parts 3 thus close the latter so as to leave an apparent height h₁ of rib 2, determined by the upper plane 3a and the top 4 of said rib 2 to advantageously constitute a non-slip surface.

Les sommets apparents 4 des nervures 2 délimitent avec la toile 3 des logements alvéolaires 5 au fond desquels est réalisé de moulage au moins un plot 6 antidérapant laissant subsister dans chaque logement alvéolaire 5 considéré, au moins une rainure d'écoulement de liquide.The visible tops 4 of the ribs 2 delimit with the fabric 3 honeycomb housings 5 at the bottom of which is molded at least one non-slip stud 6 leaving in each honeycomb housing 5 considered, at least one liquid flow groove.

Dans l'exemple présent, les plots 6 sont au nombre de quatre et sont de forme carrée. Ils sont ménagés en damier dans chaque logement alvéolaire 5 et délimitent entre eux deux rainures perpendiculaires 7 et 8 qui se coupent en leur centre et débouchent à leur extrémité respective dans une rainure périphérique 9 dont le rebord externe est constitué par le rebord dudit logement alvéolaire 5, en l'occurrence le sommet 4 des nervures 2.In the present example, the studs 6 are four in number and are square in shape. They are arranged in a checkerboard pattern in each honeycomb housing 5 and delimit between them two perpendicular grooves 7 and 8 which intersect at their center and open at their respective ends in a peripheral groove 9 whose external rim is constituted by the rim of said alveolar housing 5 , in this case the top 4 of the ribs 2.

Un trou central 10 d'évacuation est prévu à l'intersection des rainures perpendiculaires.A central discharge hole 10 is provided at the intersection of the perpendicular grooves.

A noter que la dalle 1 comporte un rebord externe supérieur 11, arrondi de manière à supprimer l'effet de marche.Note that the slab 1 has an upper outer rim 11, rounded so as to eliminate the walking effect.

Tel qu'apparaissant à la figure 2, la structure alvéolaire comporte à la partie inférieure 2b des nervures 2 portant sur le sol, des ajours 12 mettant en communication les alvéoles entre elles, afin de permettre la libre circulation de liquide sous le revêtement constitué par les dalles 1.As shown in FIG. 2, the honeycomb structure has ribs 2 bearing on the ground at the lower part 2b, openings 12 putting the cells in communication with each other, in order to allow the free circulation of liquid under the covering constituted by the tiles 1.

Les dalles 1 ainsi définies sont obtenues de manière monobloc au cours d'une même opération de moulage d'un élastomère. Elle sont reliées entre elles, pour constituer un revêtement de sol, par un système d'amarrage 20 désigné dans son ensemble.The slabs 1 thus defined are obtained in a single piece during the same molding operation of an elastomer. They are connected together, to constitute a floor covering, by a mooring system 20 designated as a whole.

Les figures 3 et 4 représentent un tel système d'amarrage 20 constitué par quatre pieds 21 de forme et de dimensions correspondant à quatre alvéoles d'angle de quatre dalles 1A, 1B, 1C, 1D, à structure alvéolaire telles que décrites ci-dessus et dans lesquelles alvéoles s'emboîtent les pieds 21 au montage.Figures 3 and 4 show such a mooring system 20 consisting of four feet 21 of shape and dimensions corresponding to four corner cells of four slabs 1A, 1B, 1C, 1D, with honeycomb structure as described above and in which cells fit the feet 21 during assembly.

Les pieds 21 sont reliés entre eux par des ponts 22 de liaison disposés à la base desdits pieds 21, dans leur axe transversal et ont une section 23 correspondant aux ajours 12 ménagés à la partie inférieure 2b des nervures 2 qui les chevauchent au montage. Ainsi les dalles 1A, 1B, 1C, 1D .. posent sur le sol sur un même plan que les systèmes 20 qui les relient, assurant une portée uniforme de l'ensemble.The feet 21 are interconnected by bridges 22 connecting arranged at the base of said feet 21, in their transverse axis and have a section 23 corresponding to the openings 12 formed in the lower part 2b of the ribs 2 which overlap them during assembly. Thus the slabs 1A, 1B, 1C, 1D .. lay on the ground on the same plane as the systems 20 which connect them, ensuring a uniform range of the assembly.

Les pieds 21 sont espacés entre eux d'une valeur sensiblement égale aux épaisseurs "e" de deux nervures 2 de deux alvéoles d'angle, de deux dalles 1 adjacentes.The feet 21 are spaced apart from each other by a value substantially equal to the thicknesses "e" of two ribs 2 of two corner cells, of two adjacent slabs 1.

De manière à permettre l'évacuation de liquide susceptible de stagner dans le fond 24 des pieds 21, un trou d'évacuation 25 est percé en son centre.In order to allow the evacuation of liquid liable to stagnate in the bottom 24 of the feet 21, an evacuation hole 25 is drilled in its center.

Pour une facilité d'introduction des pieds 21 dans les alvéoles des dalles 1, les extrémités libres desdits pieds 21 comportent un biseau 26.For ease of introduction of the feet 21 into the cells of the slabs 1, the free ends of the said feet 21 have a bevel 26.

Le système d'amarrage 20 qui vient d'être décrit est obtenu de manière monobloc au cours d'une même opération de moulage d'un même élastomère que celui utilisé pour le moulage des dalles 1. Ainsi, les pieds 21 ne sauraient pas constituer des points durs sous les dalles 1.The mooring system 20 which has just been described is obtained in a single piece during the same molding operation of the same elastomer as that used for molding slabs 1. Thus, the feet 21 cannot constitute hard spots under the tiles 1.

Un revêtement de sol avec de telles dalles 1 assemblées avec de tels systèmes d'amarrage 20 est aisément réalisé quelle que soit la géométrie de la salle et les obstacles à contourner, tels que piliers de soutènement par exemple. En effet, un tel matériau est découpable à la demande par un outil tranchant au droit de chaque alvéole sans perte d'esthétique, ni d'efficacité de la dalle concernée car chaque alvéole constituant la dalle 1 a des caractéristiques propres et est entièrement indépendante des autres alvéoles.A floor covering with such slabs 1 assembled with such mooring systems 20 is easily produced whatever the geometry of the room and the obstacles to be circumvented, such as support pillars for example. Indeed, such a material can be cut on demand by a cutting tool in line with each cell without loss of aesthetics or efficiency of the slab concerned because each cell constituting slab 1 has its own characteristics and is entirely independent of other cells.
