Description
La présente invention concerne tout d'abord un cadre pour étages d'un échafaudage constitué d'un ensemble d'étages superposés et emboîtés, ce cadre comportant un montant vertical muni de moyens d'emboîtage lui permettant de s'emboîter sur le montant vertical correspondant d'un cadre sous-jacent, ce cadre comportant un contreventement de liaison dudit montant à une main verticale pourvue d'un moyen de verrouillage, cette main pouvant s'engager latéralement, par pivotement autour dudit montant, et être verrouillée, dès sa mise en butée, sur le montant vertical d'un cadre voisin semblable dudit étage.The present invention relates first of all to a frame for stages of a scaffolding consisting of a set of superimposed and nested stages, this frame comprising a vertical upright provided with fitting means allowing it to fit onto the vertical upright corresponding to an underlying frame, this frame comprising a bracing connecting said upright to a vertical hand provided with a locking means, this hand being able to engage laterally, by pivoting around said upright, and to be locked as soon as it is abutment, on the vertical upright of a similar neighboring frame of said stage.
On connaît déjà un échafaudage comportant des montants verticaux munis de moyens d'emboîtage permettant leur superposition et de moyens d'accrochage disposés latéralement et permettant l'accrochage de cadres de contreventement munis de moyens d'accrochage complémentaires agencés pour coopérer avec les moyens d'accrochage des susdits montants verticaux. Dans un tel échafaudage, chaque cadre de contreventement comporte au moins une traverse de liaison présentant une extrémité libre munie de moyens de fixation disposés et agencés pour solidariser, de façon démontable et au moins dans des directions horizontales, la susdite extrémité libre avec un cadre de contreventement adjacent.There is already known a scaffolding comprising vertical uprights provided with fitting means allowing their superposition and hooking means arranged laterally and allowing the hooking of bracing frames provided with complementary hooking means arranged to cooperate with the means of attachment of the above vertical uprights. In such a scaffolding, each bracing frame comprises at least one connecting crosspiece having a free end provided with fixing means arranged and arranged to secure, in a removable manner and at least in horizontal directions, the aforesaid free end with a frame of adjacent bracing.
Le document DE 1 957 913 décrit un cadre pour étages d'un échaufaudage constitué d'un ensemble d'étages superposés et emboîtés, ce cadre comportant un montant vertical muni de moyens d'emboîtage lui permettant de s'emboîter sur le montant vertical correspondant d'un cadre sous-jacent. Ce cadre comporte un contreventement de liaison du montant à une main verticale pourvue d'un moyen de verrouillage, cette main pouvant s'engager latéralement, par pivotement autour du montant, et être verrouillée, dès sa mise en butée, sur le montant vertical d'un cadre voisin semblable dudit étage.Document DE 1 957 913 describes a frame for floors of a scaffolding consisting of a set of superimposed and nested stages, this frame comprising a vertical upright provided with fitting means allowing it to fit onto the corresponding vertical upright of an underlying framework. This frame comprises a bracing connecting the upright to a vertical hand provided with a locking means, this hand able to engage laterally, by pivoting around the upright, and be locked, as soon as it stops, on the vertical upright of a similar neighboring frame of said stage.
Cependant le contreventement est ici triangulaire, ce qui nécessite aux extrémités inférieure et supérieure un cadre supplémentaire.However, the bracing here is triangular, which requires an additional frame at the lower and upper ends.
La présente invention vise à obtenir la simplification d'une telle structure, et à cet effet, un cadre pour étages d'un échafaudage du type mentionné au début est caractérisé en ce que ledit contreventement de liaison dudit montant à ladite main verticale comporte deux longerons horizontaux dont l'espacement n'est que légèrement inférieur à la hauteur de ladite main verticale, de sorte à pouvoir assurer entre eux, au voisinage dudit montant, le blocage de la main verticale du cadre voisin de l'étage.The present invention aims to obtain the simplification of such a structure, and for this purpose, a frame for floors of a scaffolding of the type mentioned at the start is characterized in that said bracing connecting said upright to said vertical hand comprises two beams horizontal whose spacing is only slightly less than the height of said vertical hand, so as to be able to ensure between them, in the vicinity of said upright, the blocking of the vertical hand of the neighboring frame of the floor.
Ainsi, chaque étage de l'échafaudage pourra être constitué de trois, quatre, cinq cadres verticaux semblables, comportant chacun un montant à une extrémité et une main à l'extrémité opposée, la main de chaque cadre étant engagée et verrouillée sur le montant du cadre voisin du même étage, et l'échafaudage pouvant alors être constitué par un certain nombre de tels étages identiques superposés et emboîtés.Thus, each stage of the scaffolding may be made up of three, four, five similar vertical frames, each comprising a post at one end and a hand at the opposite end, the hand of each frame being engaged and locked on the post of neighboring frame of the same floor, and the scaffolding can then be constituted by a number of such identical stages superimposed and nested.
Par l'expression "cadres verticaux semblables", il faut entendre des cadres verticaux dont les parties extrêmes sont identiques mais dont les contreventements peuvent avoir tous la même longueur ou plusieurs longueurs différentes. Quand les contreventements auront tous la même longueur, les cadres seront absolument identiques, et tous les étages de l'échafaudage pourront alors être carrés. Avec deux longueurs différentes de contreventement, par exemple, on pourra opposer deux à deux des cadres de même longueur sur deux côtés opposés de l'étage, et deux cadres de longueur différente sur les deux autres côtés opposés, ce qui permettra d'obtenir des étages rectangulaires de tout module.By the expression "similar vertical frames" is meant vertical frames whose end portions are identical but whose braces may all be the same length or several different lengths. When the braces are all the same length, the frames will be absolutely identical, and all the scaffolding floors can then be square. With two different lengths of bracing, for example, it will be possible to oppose two to two of the frames of the same length on two opposite sides of the floor, and two frames of different length on the other two opposite sides, which will make it possible to obtain rectangular floors of any module.
On comprend que toute autre forme d'étage est également possible, avec des côtés de longueurs égales ou différentes : pentagonale, hexagonale, etc.It is understood that any other form of storey is also possible, with sides of equal or different lengths: pentagonal, hexagonal, etc.
On évite en tout cas que les cadres ne subissent des déformations dans leur plan vertical, puisque l'extrémité du cadre opposée à son montant vertical sera soutenue par le montant vertical du cadre voisin, comme cela sera mieux vu par la suite.In any case, it is avoided that the frames undergo deformations in their vertical plane, since the end of the frame opposite to its vertical upright will be supported by the vertical upright of the neighboring frame, as will be seen more clearly below.
Avantageusement, le montant vertical étant tubulaire, ladite main verticale est constituée d'une tôle conformée en gouttière à section transversale sensiblement semi-circulaire, s'ouvrant vers l'extérieur de l'étage et dans une direction sensiblement perpendiculaire au plan du cadre.Advantageously, the vertical upright being tubular, said vertical hand consists of a sheet shaped like a gutter with a substantially semi-circular cross section, opening towards the outside of the floor and in a direction substantially perpendicular to the plane of the frame.
De la sorte, la main verticale épouse étroitement le montant sur lequel elle est verrouillée, et ceci sur la hauteur maximale, ce qui contribue à assurer la rigidité de l'échafaudage, en limitant les jeux.In this way, the vertical hand closely follows the upright on which it is locked, and this over the maximum height, which contributes to ensuring the rigidity of the scaffolding, by limiting the play.
Cette disposition, en outre, offre la possibilité de monter tous les cadres successivement depuis l'intérieur de l'échafaudage en cours de montage, l'ouvrier ayant les pieds sur un plancher posé sur les cadres inférieurs, ce qui assure sa sécurité.This arrangement, moreover, offers the possibility of mounting all the frames successively from inside the scaffolding being erected, the worker having his feet on a floor placed on the lower frames, which ensures his safety.
Avantageusement encore, ledit moyen de verrouillage est constitué par un loquet monté pivotant sur un bord de ladite main verticale et propre à être bloqué en position sensiblement horizontale devant un montant logé dans ladite main.Advantageously also, said locking means is constituted by a latch pivotally mounted on an edge of said vertical hand and suitable for being locked in a substantially horizontal position in front of an upright housed in said hand.
Un mode d'exécution de l'invention va maintenant être décrit à titre d'exemple nullement limitatif avec référence aux figures du dessin ci-annexé dans lequel :

- la figure 4 est une vue en élévation de ce moyen de verrouillage ;
- la figure 5 est une vue en perspective d'un échafaudage en cours de montage conforme à l'invention, constitué d'un ensemble d'étages superposés et emboîtés, eux-mêmes constitués de cadres conformes à celui des figures 1 et 2 ;
- la figure 6 est une vue en élévation de l'échafaudage ; et
- la figure 7 est une vue en coupe transversale par la ligne VII-VII de la figure 6.

- Figure 2 is a plan view of this frame;
- Figure 3 is a cross-sectional view of the tubular upright of the frame, showing the planar locking means;
- Figure 4 is an elevational view of this locking means;
- Figure 5 is a perspective view of a scaffolding during assembly according to the invention, consisting of a set of superimposed and nested stages, themselves made of frames according to that of Figures 1 and 2;
- Figure 6 is an elevational view of the scaffolding; and
- FIG. 7 is a cross-sectional view on line VII-VII of FIG. 6.
Sur les différentes figures, chaque cadre pour étage d'échafaudage a été désigné par la référence 1. Ce cadre est constitué d'un montant tubulaire 2 relié par un contreventement 3 à une main en forme de gouttière à section sensiblement semi-circulaire 4. Le contreventement est constitué de deux barres 5 reliées par une traverse médiane 6 et soudées à une extrémité au montant 2 et à l'autre extrémité à une barre 7 sur laquelle est fixée la main 4.In the various figures, each frame for a scaffolding stage has been designated by the reference 1. This frame consists of a tubular upright 2 connected by a brace 3 to a hand in the form of a gutter with a substantially semi-circular section 4. The bracing consists of two bars 5 connected by a central crosspiece 6 and welded at one end to the upright 2 and at the other end to a bar 7 on which the hand 4 is fixed.
Le montage d'un échafaudage constitué par l'empilage d'étages formés de tels cadres 1 est extrêmement simple: on pose deux montants 2 verticalement sur le sol, à l'écartement voulu, et l'on fait pivoter l'un des cadres sur son montant, de l'intérieur vers l'extérieur de l'échafaudage, pour amener sa main 4 sur l'autre montant ; on procède de même avec le second cadre, dont on amène la main sur le montant d'un troisième cadre situé à l'équerre des deux précédents et ainsi de suite jusqu'à la constitution d'un premier étage carré ou rectangulaire. La figure 7 montre schématiquement, en trait mixte, quelle peut être la position 1' de chaque cadre 1 à l'intérieur de l'échafaudage avant son pivotement autour de son montant 2 dans le sens des flèches. Au fur et à mesure de cette pose des cadres, le montant 2 du cadre suivant peut être verrouillé dans la main 4 du cadre précédent par un loquet 8 tel que mieux visible sur les figures 3 et 4. Ce loquet est constitué d'une plaque montée sur le flanc 7 de la main 4 par un axe de pivotement 9 ; un talon 10 de cette plaque, en venant buter sur le chant du flanc 7, peut la maintenir en position horizontale, ce qui empêche le montant 2 de s'échapper de la main 4. Pour le déverrouillage, il suffit de soulever le loquet 8 grâce à la plaquette 11.The assembly of a scaffolding constituted by the stacking of stages formed by such frames 1 is extremely simple: two uprights 2 are placed vertically on the ground, at the desired spacing, and one of the frames is pivoted on its upright, from the inside to the outside of the scaffolding, to bring its hand 4 onto the other upright; one proceeds in the same way with the second frame, which one brings the hand on the amount of a third frame located at the square of the two preceding ones and so on until the constitution of a first square or rectangular stage. FIG. 7 shows diagrammatically, in phantom, what may be the position 1 ′ of each frame 1 inside the scaffolding before it is pivoted around its upright 2 in the direction of the arrows. As this frames are placed, the upright 2 of the next frame can be locked in hand 4 of the previous frame by a latch 8 as best seen in Figures 3 and 4. This latch consists of a plate mounted on the side 7 of the hand 4 by a pivot axis 9; a heel 10 of this plate, coming into abutment on the edge of the sidewall 7, can keep it in a horizontal position, which prevents the upright 2 from escaping with the hand 4. For unlocking, it suffices to lift the latch 8 thanks to the plate 11.
Lorsque l'étage de base est ainsi constitué et verrouillé, on emboîte le montant 2 d'un cinquième cadre 1 sur le montant 2 d'un des cadres de l'étage de base, et l'on procède au montage et au verrouillage du second étage de la même manière que pour le premier, on monte les planchers de travail P1, P2..., et ainsi de suite jusqu'à atteindre la hauteur d'échafaudage voulue.When the base stage is thus formed and locked, the post 2 of a fifth frame 1 is fitted onto the post 2 of one of the frames of the base stage, and the assembly and locking of the second stage in the same way as for the first, the working floors P 1 , P 2, etc. are mounted, and so on until reaching the desired scaffolding height.
En 12 à la figure 6, on a représenté des vérins à vis permettant de régler l'aplomb de l'échafaudage, et en 13, en tête des montants 2 supérieurs, d'autres vérins à vis permettant le réglage du niveau de fourches ou analogues 14 de réception de madriers, pour la constitution d'un plancher de coffrage, par exemple.At 12 in FIG. 6, screw jacks are shown making it possible to adjust the plumb of the scaffolding, and in 13, at the top of the upper uprights 2, other screw jacks allowing the level of forks to be adjusted or analogs 14 for receiving planks, for constituting a formwork floor, for example.
Un tel échafaudage peut avoir tous les autres usages envisageables dans la technique du bâtiment (échafaudage de service, étaiement, etc.).Such scaffolding can have all the other uses that can be envisaged in the building technique (service scaffolding, shoring, etc.).
Grâce à l'invention, en outre, les cadres forment un garde de corps de sécurité conforme à la règlementation française.Thanks to the invention, moreover, the frames form a security bodyguard in accordance with French regulations.
