Description
Perfectionnements aux blocs de protection en béton, pour chantiers longs par des véhicules. Improvements to concrete protection blocks, for long sites by vehicles.
L'invention est relative aux blocs de protection en béton, pour chantiers longés par des véhìcules, en particulier pour chantiers routiers. Comme on le sait, de tels blocs sont agencés de manière à être posés et reliés mécaniquement bout à bout afin de délimiter le chantier par une clôture continue qui doit être pratiquement infranchissable pour les véhicules circulant sur une voie adjacente. The invention relates to concrete protective blocks, for construction sites bordered by vehicles, in particular for road construction sites. As is known, such blocks are arranged so as to be laid and mechanically connected end to end in order to delimit the site by a continuous fence which must be practically impassable for vehicles traveling on an adjacent lane.
Ces blocs doivent donc avoir un poids, une stabilité et une adhérence au sor tels qu'ils ne risquent pas d'être déplacés latéralement (tout au moins-de façon notable) ou renversés par le choc en biais de véhicules et une forme telle que, dans le cas d'un tel choc, ils tendent à ramener ces roues à l'écart de ladite clôture. De plus, ils doivent pouvoir être saisis et mis en place aisément par des engins de manutention et reliés ensemble par des moyens ne créant pas de discontinuité apparente dans la clôture. Ils doivent enfin pouvoir être stockés sous un encombrement aussi faibles que possible.These blocks must therefore have a weight, stability and adhesion to the sor such that they are not likely to be displaced laterally (at least-noticeably) or overturned by the impact on the bias of vehicles and a shape such as , in the event of such a shock, they tend to bring these wheels away from said fence. In addition, they must be able to be gripped and put in place easily by handling equipment and connected together by means that do not create any apparent discontinuity in the fence. Finally, they must be able to be stored in a space that is as small as possible.
tes blocs de protection connus ont en général urle surface prismatique, c'est-à-dire une surface engendrée géométriquement par une droite de direction horizontale fixe qui se déplace en s'appuyant constamment sur le pourtour d'un polygone plan, symétrique par rapport à un plan vertical parallèle à cette direction, cette surface étant épanouie à sa partie inférieure pour constituer une embase. your known protective blocks generally have a prismatic surface, that is to say a surface geometrically generated by a straight line of fixed horizontal direction which moves by constantly pressing on the periphery of a plane polygon, symmetrical with respect to to a vertical plane parallel to this direction, this surface being opened out at its lower part to constitute a base.
Dans ce contexte, les expressions telles que "horizontal" ou "vertical" s'entendent lorsque le bloc de protection repose sur son embase, en position d'utilisation. In this context, expressions such as "horizontal" or "vertical" are understood when the protective block rests on its base, in the position of use.
L'invention a pour but de perfectionner ces blocs de protection. Elle a en particulier pour but de faciliter leur moulage et leur démoulage et, de préférence en outre, de faciliter leur liaison bout à bout. The invention aims to improve these protective blocks. It aims in particular to facilitate their molding and demolding and, preferably moreover, to facilitate their connection end to end.
A cet effet, le bloc le protection en béton conforme à l'invention, dont la forme est prismatique et dont le profil, symétrique par rapport à un plan vertical, est formé d'un trapèze avec un sommet et une base parallèles et horizontaux, la base étant nettement plus grande que le sommet, est essentiellement caractérisé en ce que les côtés du trapèze sont des côtés curvilignes concaves et en ce que les faces transversales du bloc portent des moyens de liaison en saillie susceptibles d'être emboîtés l'un dans l'autre, entre blocs voisins, par un simple déplacement vertical relatif. To this end, the concrete protection block according to the invention, whose shape is prismatic and whose profile, symmetrical with respect to a vertical plane, is formed by a trapezoid with a parallel and horizontal vertex and base, the base being significantly larger than the top, is essentially characterized in that the sides of the trapezoid are concave curvilinear sides and in that the transverse faces of the block carry projecting connecting means capable of being fitted one in the other, between neighboring blocks, by a simple relative vertical displacement.
De tels blocs de protection sont faciles à mouler et démouler, car ils ne possèdent pas de parties en creux, à l'exception de trous de manutention éventuels qui seront décrits ci-après. Ils peuvent de plus être stockés têtebêche sous un volume réduit, sans parties en saillie susceptibles d'être ainsi détériorées. Ils sont en outre faciles à assembler bout à bout. Such protective blocks are easy to mold and demold, since they do not have recessed parts, with the exception of possible handling holes which will be described below. They can also be stored head to tail in a reduced volume, without protruding parts liable to be thus damaged. They are also easy to assemble end to end.
Selon un mode de réalisation préféré, les moyens de liaison d'un tel bloc de protection sont constitués, sur une face transversale, par la partie en saillie d'un fer à I et, sur l'autre face transversale, par un fer en C, ces deux fers ayant été noyés partiellement dans le béton lors du moulage du bloc de protection
De tels moyens de liaison sont faciles à mettre en place au moulage et d'un bas prix de revient.According to a preferred embodiment, the connecting means of such a protective block are constituted, on a transverse face, by the projecting part of an I-iron and, on the other transverse face, by a C, these two irons having been partially embedded in the concrete during the molding of the protective block
Such connecting means are easy to set up during molding and at a low cost price.
La hauteur préférée du bloc de béton est de l'ordre de 900 mm, ce qui lui permet de constituer un élément de clôture à lui seul, c'est-à-dire sans glissière métallique (ou rail de sécurité) rapporté sur son sommet. The preferred height of the concrete block is of the order of 900 mm, which allows it to constitute a fence element on its own, that is to say without a metal slide (or safety rail) attached to its top. .
Le poids préféré du bloc de béton est de l'ordre de 1700 kg, ce qui constitue un excellent compromis entre les deux exigences contradictoires suivantes : facilité de manuten .tion et de mise en place d'une part et stabilité en position d'utilisation d'autre part. The preferred weight of the concrete block is around 1,700 kg, which constitutes an excellent compromise between the following two contradictory requirements: ease of handling and positioning on the one hand and stability in the position of use. on the other hand.
Pour faciliter encore cette manutention, le bloc de protection est muni d'au moins deux trous horizontaux parallèles qui le traversent de part en part perpendiculairement a son plan de symétrie vertical et qui sont placés à égale distance des faces transversale. Il suffit alors d'introduire dans ces trous des fers ronds qui sont disponi bleus pratiquement sur tous les chantiers, pour permettre à un engin de manutention de chantier de saisir des blocs à l'aide de ces fers, par l'intermédiaire d'élingues par exemple. To further facilitate this handling, the protective block is provided with at least two parallel horizontal holes which pass right through it perpendicularly to its vertical plane of symmetry and which are placed at equal distance from the transverse faces. It then suffices to introduce into these holes round irons which are available on practically all construction sites, to allow a site handling machine to grasp blocks using these irons, by means of slings. for example.
L'invention va être décrite plus en détail ci-après à l'aide des dessins annexés qui en illustrent un mode de réalisation préféré. The invention will be described in more detail below using the accompanying drawings which illustrate a preferred embodiment.
Les figures t à 4 représentent un bloc- de protection conforme à l'invention, respectivement en perspective, en élévation r en plan et en vue de bout. Figures t to 4 show a protective block according to the invention, respectively in perspective, in elevation r in plan and in end view.

coulage du béton.pouring concrete.
Comme le montre plus particulièrement les figures 1 et 4, le bloc de protection 1 conforme à l'invention a une forme prismatique, dont le profil, symétrique par rapport à un plan vertical P, est formé d'un trapèze avec un sommet 2 et une base 3 parallèles et horizontaux, la base 3 étant nettement plus grande que le sommet 2. Les côtés 4du trapèze sont des côtés curviignes concaves, sans point d'inflexion, c'est-à-dire sans changement de sens de la courbure, à l'exception des côtés verticaux 5 de l'embase usuelle 6. Les faces transversales 7 et 8 du bloc 1 portent des moyens de liaison en saillie 9 et 10, susceptibles d'être emboîtés l'un dans l'autre, entre blocs voisins, par un déplacement vertical relatif. As shown more particularly in FIGS. 1 and 4, the protective block 1 according to the invention has a prismatic shape, the profile of which, symmetrical with respect to a vertical plane P, is formed by a trapezoid with a vertex 2 and a base 3 which is parallel and horizontal, the base 3 being considerably larger than the apex 2. The sides 4 of the trapezoid are curved curved sides, without inflection point, that is to say without change of direction of the curvature, with the exception of the vertical sides 5 of the usual base 6. The transverse faces 7 and 8 of the block 1 carry projecting connection means 9 and 10, capable of being fitted one inside the other, between blocks neighbors, by a relative vertical displacement.
Selon le mode de réalisation représenté, ces moyens de liaison sont constitués, sur la face transversale 7, par la partie en saillie d'un fer à I 11 (voir la figure 5) et, sur la face transversale opposée 8, par un fer en C 12. Le fer à I 11 est de préférence un profil I PN de 180 x 80 mm qui est partiellement noyé verticalement dans le béton du bloc 1, en faisant saillie sur une distance a égale à environ 75 mm sur la face transversale 7 et en s'étendant sur la moitié supérieure de la hauteur de cette face 7. te fer en C 12 est de préférence un profil 100 x 50 mm s'étendant pratiquement sur toute la hauteur de la face transversale 8, ce fer 12 étant noyé verticalement dans le béton de façon que l'ouverture 13 du profil débouche sur la face transversale 8 et que la surface extérieure des branches 14 limitant cette ouverture 13 se disposent dans le même plan que cette face transversale. Pour faciliter l'engagement e a partie saillante du profil IPN tl dans le profil en C 12 ou inversement, les ailes en saillie du profil 11 sont de préférence biseautées à leurs parties inférieures et supérieures, comme indiqué en 15. According to the embodiment shown, these connecting means are constituted, on the transverse face 7, by the projecting part of an iron I 11 (see Figure 5) and, on the opposite transverse face 8, by a iron in C 12. The iron at I 11 is preferably an I PN profile of 180 x 80 mm which is partially embedded vertically in the concrete of block 1, projecting over a distance a equal to approximately 75 mm on the transverse face 7 and extending over the upper half of the height of this face 7. the C 12 iron is preferably a 100 x 50 mm profile extending practically over the entire height of the transverse face 8, this iron 12 being embedded vertically in the concrete so that the opening 13 of the profile opens onto the transverse face 8 and the outer surface of the branches 14 limiting this opening 13 are arranged in the same plane as this transverse face. To facilitate engagement with the projecting part of the IPN profile tl in the C profile 12 or vice versa, the projecting wings of the profile 11 are preferably bevelled at their lower and upper parts, as indicated in 15.
Le bloc de béton 1 est muni d'au oins deux trous horizontaux parallèles 16 qui le traversent perpendiculairement au plan P et qui sont destinés à recevoir des fers ronds permettant à des engins de manutention de saisir ce bloc. The concrete block 1 is provided with at least two parallel horizontal holes 16 which cross it perpendicularly to the plane P and which are intended to receive round irons allowing handling equipment to grasp this block.
L'embase 6 comporte de préférence au moins une encoche 17 pour faciliter l'écoulement des eaux. The base 6 preferably comprises at least one notch 17 to facilitate the flow of water.
