Abstract

The insert has a tubular partition (1) defining a housing for accommodating a foot of a post, and horizontal beams (4, 5) extending to a base of the partition. The beams constitute a positioning and anchoring unit for positioning and anchoring the insert with prestressed or reinforcing cords (6, 7) of a slab. Arch-buttresses or buttresses i.e. projecting wings (11-14) extend from top of the partition till an end provided with cover strips (15, 16), which are moved away from the partition and located at a determined height with respect to a height of the positioning and anchoring unit.

Description

La présente invention concerne un dispositif d'encastrement d'un potelet de garde-corps destiné aux dalles minces, notamment préfabriquées en usine, en béton armé ou en béton précontraint, ou bien fabriquées in situ avec une armature métallique, pour assurer la sécurité passive collective des ouvriers et usagers de ces dalles lors de leur mise en place sur chantier et au cours de la construction de l'immeuble auquel elles appartiennent.The present invention relates to a device for embedding a guardrail post for thin slabs, especially prefabricated in the factory, reinforced concrete or prestressed concrete, or manufactured in situ with a metal frame, to ensure passive safety collective workers and users of these slabs during their establishment on site and during the construction of the building to which they belong.

ARRIERE PLAN DE L'INVENTIONBACKGROUND OF THE INVENTION

Les garde-corps servent, pendant la construction d'un bâtiment, à prévenir la chute d'objets ou de personnes se trouvant en périphérie d'une toiture, d'une dalle, d'une trémie d'escalier.... Ils sont utilisés en concurrence avec d'autres systèmes de sécurité tels que des lignes de vie associés à des filins et des harnais. Leur avantage réside dans le fait qu'ils coopèrent à la formation d'une barrière temporaire à la périphérie d'une surface à l'intérieur de laquelle la sécurité des personnes est totale bien qu'elles disposent d'une grande liberté de mouvement. Leur mise en place est cependant plus lourde que celle des autres systèmes car il faut réaliser une liaison efficace, bien que temporaire, entre chaque poteau de barrière et la dalle qui porte la surface sur laquelle évolue le personnel, à la périphérie de celle-ci.The guardrails are used, during the construction of a building, to prevent the fall of objects or people located on the periphery of a roof, a slab, a stair hopper .... They are used in competition with other safety systems such as lifelines associated with ropes and harnesses. Their advantage lies in the fact that they cooperate in the formation of a temporary barrier on the periphery of a surface within which the security of the people is total although they have a great freedom of movement. Their installation is however heavier than that of other systems because it is necessary to achieve an effective, although temporary, between each barrier post and the slab that carries the surface on which the staff evolves, on the periphery thereof .

On a pensé pratiquer des réserves dans la dalle avant la coulée du béton dans lesquelles il sera possible sur chantier d'emplanter les pieds de chaque poteau de barrière. Ces réserves sont le plus souvent des tronçons de tubes métalliques maintenus verticaux sur deux fils d'armature ou de tension par deux points de soudure qui n'ont que le rôle de maintenir en place les tronçons de tube lors de la coulée à l'encontre des efforts de poussée du béton déversé dans le moule. Il n'est pas rare dans ce cas que la résistance du béton, au voisinage du bord, cède sous un effort de poussée horizontale appliqué sur le poteau qui agit comme un bras de levier suffisamment puissant pour faire éclater le béton entre le tronçon tubulaire d'accueil du pied du poteau et la rive de la dalle. Il faut en effet rappeler que l'épaisseur d'une dalle préfabriquée (ou prédalle) est de l'ordre de cinq centimètres, ce qui est une hauteur d'encastrement faible.It was thought to practice reserves in the slab before pouring concrete in which it will be possible on site to plant the feet of each barrier post. These reserves are most often sections of metal tubes held vertical on two reinforcing wire or tension by two solder points which have only the role of keeping in place the pipe sections during the casting against thrust forces of the concrete poured into the mold. It is not uncommon in this case that the resistance of the concrete, in the vicinity of edge, yields under a horizontal thrust force applied to the pole which acts as a lever arm powerful enough to break the concrete between the tubular section home foot post and the edge of the slab. It should be recalled that the thickness of a prefabricated slab (or pre-slab) is of the order of five centimeters, which is a low installation height.

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

Par la présente invention, on entend remédier à cet inconvénient de fragilité de la tenue du garde-corps en prévoyant une armature d'accueil du pied de chaque potelet de garde-corps qui se substitue au béton pour encaisser les efforts du type de ceux rappelés ci-dessus y résister sans dommage et constituer un répartiteur des efforts dans le béton de manière à éliminer les concentrations de contraintes pouvant conduire à la fissuration et à l'éclatement du béton.By the present invention, it is intended to remedy this disadvantage of fragility of the behavior of the railing by providing a foot reinforcement of the foot of each railing post which is substituted for the concrete to cash the efforts of the type of those recalled above to withstand it without damage and to constitute a distribution of the forces in the concrete so as to eliminate the concentrations of stresses which can lead to the cracking and the bursting of the concrete.

RESUME DE L'INVENTIONSUMMARY OF THE INVENTION

L'invention a donc pour objet un insert d'emplanture de potelet de garde-corps dans une dalle mince, notamment préfabriquée (prédalle), armée ou précontrainte, possédant des fils d'armature ou de précontrainte, qui comporte une cloison tubulaire qui définit un logement d'accueil d'un pied de potelet, au moins deux éléments extérieurs s'étendant sensiblement horizontalement à la base de cette cloison et qui constituent des éléments de positionnement et d'accrochage de l'insert à certains des fils susdits de la dalle et au moins trois arcs-boutants s'étendant depuis le sommet de la cloison tubulaire jusqu'à une extrémité équipée d'une semelle, écartée de la cloison tubulaire et située à une altitude déterminée par rapport à celle des éléments de positionnement et d'accrochage.The subject of the invention is therefore an insert for anchoring a railing post in a thin slab, in particular prefabricated (pre-slab), reinforced or pre-stressed, having reinforcing or prestressing wires, which comprises a tubular partition which defines a housing for receiving a foot of the post, at least two external elements extending substantially horizontally at the base of this partition and which constitute positioning and hooking elements of the insert to some of the above-mentioned wires of the slab and at least three flying buttresses extending from the top of the tubular partition to an end equipped with a sole, spaced apart from the tubular partition and located at a determined altitude relative to that of the positioning elements and hooking.

La fabrication d'une dalle mince (prédalle), est réalisée par coulage d'une nappe de béton dans un moule équipé de fils de précontrainte tendus. L'épaisseur de la prédalle est en général comprise entre 4 et 5 centimètres. La situation des fils de précontrainte est parfaitement connue ; elle est en général à environ 2 centimètres du fond du moule. Cette nappe de fils constitue donc une référence à laquelle est rapportée la mise en place de l'insert selon l'invention. De manière normalisée, la distance maximale existant entre deux fils voisins est de 222 millimètres. Ainsi les éléments de positionnement auront un empattement suffisant pour pouvoir reposer sur deux fils adjacents dans le cas où ils sont le plus éloignés. De préférence, ces éléments posséderont des moyens d'encliquetage de l'insert sur les fils pour les assujettir à ceux-ci avant la coulée du béton et les tenir en place malgré les chocs qu'ils auront pu subir de la part des opérateurs se déplaçant sur la nappe de fils. Ces moyens d'encliquetage pourront simplement être des encoches ou des rainures dans lesquelles les fils seront légèrement entrés en force. Par cette disposition, la paroi tubulaire de l'insert se trouve placée à bonne hauteur dans l'épaisseur de la prédalle, évitant notamment qu'elle soit trop proche de la surface inférieure de cette dernière, ce qui nuirait à la bonne tenue du béton en dessous de l'insert.The manufacture of a thin slab (pre-slab) is made by pouring a concrete sheet into a mold equipped with tensioned tendons. The thickness of the predalle is generally between 4 and 5 centimeters. The situation of prestressing wires is well known; it is usually about 2 centimeters from the bottom of the mold. This sheet of son is therefore a reference to which is reported the establishment of the insert according to the invention. In a standardized way, the maximum distance existing between two neighboring wires is 222 millimeters. Thus the positioning elements will have a sufficient wheelbase to be able to rest on two adjacent son in the case where they are farthest away. Preferably, these elements will have snap-fastening means of the insert on the son to secure them before pouring the concrete and hold them in place despite the shocks they may have suffered from the operators themselves. moving on the sheet of wires. These snap means may simply be notches or grooves in which the son will be slightly entered in force. By this arrangement, the tubular wall of the insert is placed at a good height in the thickness of the predalle, avoiding in particular that it is too close to the lower surface of the latter, which would adversely affect the good behavior of the concrete below the insert.

Pour la même raison, à savoir la précision du positionnement en altitude (en Z) de l'insert dans la prédalle, les semelles d'extrémité des arcs-boutants sont noyées dans le béton au milieu de son épaisseur, ce qui garantit une bonne résistance à l'extraction de l'insert sous l'effet d'efforts de flexion.For the same reason, namely the accuracy of the altitude positioning (in Z) of the insert in the predalle, the end insoles of the flying buttresses are embedded in the concrete in the middle of its thickness, which guarantees a good resistance to the extraction of the insert under the effect of bending forces.

Dans un mode de réalisation préféré de cet insert, chaque arc-boutant est relié à la paroi tubulaire par une collerette extérieure et est en forme de caisson ouvert en direction de la paroi tubulaire tandis que la collerette est prolongée vers le bas entre chaque arc-boutant par une paroi en forme de cloche dont le bord inférieur est à une altitude supérieure à celle des semelles d'extrémité des arcs-boutants. Cette altitude est telle que la cloche ne pénètre pas dans le béton de la prédalle. Des cloisons radiales s'étendent entre la paroi tubulaire et la cloche, ce qui participe à la résistance de la partie de l'insert qui se trouve au-dessus de la prédalle de béton.In a preferred embodiment of this insert, each buttress is connected to the tubular wall by an outer collar and is box-shaped open towards the tubular wall while the flange is extended downwards between each buttress by a bell-shaped wall whose lower edge is at an altitude higher than that of the end flanges of flying buttresses. This altitude is such that the bell does not enter the concrete of the predalle. Radial partitions extend between the tubular wall and the bell, which contributes to the strength of the part of the insert which is above the concrete slab.

Dans un souci d'économie de matière (l'insert sera fabriqué par injection de matière plastique), on aura prévu quatre arcs-boutants dont deux de ceux-ci, diamétralement opposés, possèdent des semelles qui constituent les éléments de positionnement susdits de l'insert par rapport aux fils d'armature ou de précontrainte.In order to save material (the insert will be made by plastic injection), four flying buttresses are provided, two of which, diametrically opposed, have soles which constitute the above-mentioned positioning elements. insert relative to the reinforcing or prestressing wires.

Enfin, le logement défini par la cloison tubulaire est fermé en partie supérieure par un opercule séparable et, en partie inférieure par un fond, venu d'une pièce avec ou rapporté sur l'insert, en fonction des techniques de moulage qui auront été choisies pour sa réalisation.Finally, the housing defined by the tubular partition is closed in the upper part by a separable cap and, in the lower part by a bottom, come from a piece with or attached to the insert, depending on the molding techniques that have been chosen for its realization.

Ce qui est décrit ci-dessus pour une prédalle précontrainte s'applique également pour une prédalle en béton armé ou une dalle mince fabriquée in situ.What is described above for a prestressed pre-slab applies equally to a reinforced concrete slab or a slab made in situ.

D'autres caractéristiques et avantages de l'invention ressortiront de la description donnée ci-après de deux exemples de sa réalisation.Other features and advantages of the invention emerge from the description given below of two examples of its implementation.

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

Le dispositif représenté à la figure 1 est insert conforme à l'invention. Cet insert possède une cloison tubulaire 1 fermée en partie supérieure par un opercule détachable 2 et en partie inférieure par un fond 3. Cette cloison tubulaire est ici équipée à sa base d'éléments 4 et 5 d'accrochage de l'insert à certains des fils 6 et 7 d'armature ou de précontrainte de la prédalle ou de la dalle mince à réaliser et représentée par les traits mixtes 8. Ces éléments d'accrochage sont en forme de poutres horizontales. L'une d'elles 4 comporte des encoches de clipage 9 régulièrement réparties sur sa longueur. L'autre comporte en extrémité des ailettes divergentes 10. Les encoches et les ailettes divergentes sont capables de chevaucher les fils de précontrainte comme illustré sur la figure.The device represented in figure 1 is insert according to the invention. This insert has a tubular partition 1 closed at the top by a detachable lid 2 and at the bottom by a bottom 3. This tubular partition is here equipped at its base with elements 4 and 5 of attachment of the insert to some of son 6 and 7 of reinforcement or preload of the predalle or the thin slab to achieve and represented by the dashed lines 8. These fastening elements are in the form of horizontal beams. One of them 4 has clipping notches 9 regularly distributed over its length. The other end has diverging fins 10. The divergent notches and fins are capable of overlapping the prestressing wires as shown in the figure.

La cloison 1 comporte des arcs-boutants ou des contreforts, ici sous la forme d'ailes latérales 11, 12, 13 et 14 qui sont pourvues à leur base d'une semelle 15, 16 pour les ailes 11 et 12. Pour les autres ailes, les poutres horizontales 4 et 5 jouent aussi le rôle de semelles.The partition 1 comprises flying buttresses or buttresses, here in the form of lateral wings 11, 12, 13 and 14 which are provided at their base with a sole 15, 16 for the wings 11 and 12. For the others wings, the horizontal beams 4 and 5 also play the role of soles.

La coopération de l'insert avec les fils de précontrainte fixe la position des poutres 4 et 5 ainsi que celle des semelles 15 et 16 dans l'épaisseur de la prédalle. On est de ce fait certain que le béton qui sera coulé noiera correctement la base des quatre ailes de contrefort de la cloison tubulaire. Tout couple de basculement qui est appliqué par le potelet sur la cloison tubulaire engendre des efforts sur les semelles qui sont contrés sans dommage par le béton dans lequel elles sont noyées. Les essais ont montré en effet aucune fissure ni aucun détachement ou éclatement du béton autour de l'insert, les efforts mis en jeu étant bien entendu de l'ordre de ceux qui peuvent se rencontrer sur chantier, multiplié par un coefficient de sécurité habituel.The cooperation of the insert with the prestressing wires fixes the position of the beams 4 and 5 as well as that of the flanges 15 and 16 in the thickness of the predalle. It is therefore certain that the concrete that will be cast will drown correctly the base of the four buttress wings of the tubular partition. Any tilting torque which is applied by the post on the tubular partition causes efforts on the soles which are countered without damage by the concrete in which they are embedded. The tests showed indeed no crack or any detachment or bursting of the concrete around the insert, the efforts involved being of course of the order of those who can meet on site, multiplied by a usual safety factor.

Aux figures 2 et 3, l'exemple de réalisation représenté est beaucoup plus travaillé que celui, de principe de la figure 1, ceci pour économiser au maximum la quantité de matière à employer, à performances égales. On retrouve certains des éléments précédemment décrits avec les mêmes références.To the Figures 2 and 3 , the exemplary embodiment shown is much more worked than that of the principle of figure 1 , this to save the maximum amount of material to use, equal performance. We find some of the previously described elements with the same references.

Dans le cas de ces figures, la cloison tubulaire 1 est bordée en partie supérieure d'une collerette 20 par laquelle elle est reliée à une cloche ou jupe extérieure sensiblement cylindrique 21. Cette jupe est interrompue par les quatre contreforts ou arcs-boutants décrits ci-dessus 11, 12, 13 et 14. Ceux-ci sont ici en forme de caisson ouvert en direction de la paroi tubulaire 1 comme cela est visible sur la figure 3. Ces caissons, pour les contreforts 13 et 14, se prolongent par les poutres horizontales telles que la poutre 4 rectiligne et que la poutre 5 en éventail avec ses ailettes d'extrémité 10. Pour les contreforts 11 et 12, les poutres sont pourvues des semelles 15 et 16.In the case of these figures, the tubular partition 1 is bordered in the upper part of a collar 20 by which it is connected to a substantially cylindrical outer bell or skirt 21. This skirt is interrupted by the four buttresses or flying buttresses described herein. above 11, 12, 13 and 14. These are here box-shaped open towards the tubular wall 1 as is visible on the figure 3 . These boxes, for the buttresses 13 and 14, are extended by the horizontal beams such as the rectilinear beam 4 and the fan beam 5 with its end fins 10. For the buttresses 11 and 12, the beams are provided with soles 15 and 16.

La hauteur de la cloche extérieure 21 est inférieure à celle de la paroi tubulaire 1 de sorte que son bord inférieur 21a reste au-dessus et de préférence juste au niveau de la surface supérieure du béton de la prédalle.The height of the outer bell 21 is less than that of the tubular wall 1 so that its lower edge 21a remains above and preferably just at the upper surface of the concrete of the floor plate.

Comme dans la réalisation précédente, la cloison tubulaire 1 est fermée par un opercule supérieur 22 séparable et par un fond inférieur 23 pour empêcher le logement qu'elle définit d'être rempli et par le béton au moment de la coulée de la dalle et par de l'eau pouvant geler ou des matériaux pouvant l'obstruer. Le fond peut être formé par un bouchon rapporté si cela convient mieux à sa fabrication.As in the previous embodiment, the tubular partition 1 is closed by a separable upper cap 22 and a lower bottom 23 to prevent the housing it defines to be filled and by the concrete at the time of casting of the slab and by freezing water or obstructions. The bottom may be formed by a plug reported if it is better for its manufacture.
