Description
<Desc/Clms Page number 1>
Système d'ancrage pour paroi mince et matériaux légers utilisé en construction.
Prévu pour l'ancrage dans tous matériaux de construction.
Il existe plusieurs systèmes d'ancrage sur le marché mais leur efficacité est très réduite dans le cas des matériaux légers tel que le béton cellulaire , brique creuse et panneaux en plâtre plein, de même pour les ancrages à faible profondeur et dans les parois minces.
Les systèmes ont des inconvénients.
Pour la plupart des systèmes le principe consiste à forer un trou dans la masse dans laquelle on place un dispositif nommé cheville extensible. Le principe consiste à transformer la force de traction en une force latérale exercée sur la paroi du trou et de ce fait bloquer le dispositif en fonction de la traction exercée sur la tige centrale. Il existe aussi la possibilité de fixer la tige centrale à l'aide d'un adhésif chimique. Ils ont tous un inconvénient majeur ; leurs caractéristiques en traction sont en proportion de la profondeur d'ancrage et du diamètre de la tige centrale sur laquelle la traction est exercée.
En principe le cône de répartition des forces dans la masse est de +/-60 à partir du bout de la tige dans le fond du trou vers la paroi du côté de la traction.
<Desc/Clms Page number 2>
L'invention telle qu'elle est caractérisée dans les revendications a pour but de remédier à la plupart des inconvénients.
Le principe est différent en ce sens qu'il n'y a pas de tension statique sur les parois des trous. La force de traction est répartie sur plusieurs tiges ou bras ancrés dans la masse à un angle déterminé par rapport à la vis de traction centrale. De ce fait la force de traction est répartie sur une plus grande surface dans la masse.
D'après la disposition des tiges par rapport au corps central une partie de la force de traction peut être transformée en force de torsion dans la masse, de ce fait la profondeur d'ancrage sera fortement réduite par rapport aux principes existants pour une même force de traction.
L'invention est exposée ci-après plus en détails à l'aide de dessins représentant seulement deux modes d'exécution.
La figure 1 représente une vue de face, montrant un corps cylindrique (1) avec au centre un trou (2) dans lequel est placé une vis de traction (3). Dans le corps cylindrique (1) il y a trois trous (4) forés en oblique qui partent de la surface supérieure sous un angle déterminé et aboutissent dans la surface inférieure du corps cylindrique. La partie supérieure des trous (4) est légèrement plus grande en diamètre. Dans ces trous sont poussées trois tiges (5) qui d'un côté ont un élargissement de leur diamètre formant une tête ; poussée à fond la tête des tiges se loge dans

Une rondelle (6) d'un diamètre +/-égal au diamètre du corps (1) vient se placer sur la vis centrale qui après serrage de l'ensemble va empêcher les tiges de remonter.

La fig. (2) montre une conception différente du principe.
ZD Il n'y a pas de corps central et l'ensemble est constitué de plusieurs pièces (7) superposées comme des bras. Ces pièces ont une tige ou profil JD qui abouti sur une partie plate (8) percée d'un trou au centre (9). L'angle entre la partie plate et la tige est déterminé d'après l'emploi et la 2D e

matière dans laquelle il sera employé. Les bras sont empilés les uns sur les autres avec un décalage angulaire. tD Le bras inférieur (10) possède un filetage intérieur (M) dans la partie centrale qui va recevoir la vis de traction (12). Les autres bras ont la partie plate plus mince ce qui forme un angle vif (13) entre la surface inférieure du bras et la tige. De ce fait le bras va appuyer sur le côté du bras précédent au moment de la traction.
Après l'empilage des bras (généralement trois ou plus) la partie supérieure du dernier vient à fleur de la surface de la paroi. Puis on place une rondelle (14) avant de serrer l'ensemble.

Deuxième mode d'ancrage.
Comme dans le premier cas on fore avec un outil une cavité dans la masse. Dans cette cavité on introduit un gabarit de forage à travers lequel on va forer des trous dans la masse. Le gabarit de forage est enlevé et on introduit le premier bras avec filet dans le trou inférieur de la cavité et ensuite les autres. Quand les bras sont installés on introduit la vis de traction à travers les trous dans les bras jusqu'au filet dans le bras inférieur et l'ensemble est prêt à recevoir l'objet à fixer.

Anchoring system for thin walls and light materials used in construction.
Designed for anchoring in all construction materials.
There are several anchoring systems on the market but their effectiveness is very reduced in the case of light materials such as aerated concrete, hollow brick and solid plaster panels, the same for anchors at shallow depths and in thin walls.
Systems have drawbacks.
For most systems, the principle consists in drilling a hole in the mass in which a device called an extensible anchor is placed. The principle consists in transforming the tensile force into a lateral force exerted on the wall of the hole and thereby blocking the device according to the traction exerted on the central rod. There is also the possibility of fixing the central rod using a chemical adhesive. They all have one major drawback; their traction characteristics are in proportion to the anchoring depth and the diameter of the central rod on which the traction is exerted.
In principle the cone of distribution of forces in the mass is +/- 60 from the end of the rod in the bottom of the hole towards the wall on the side of the traction.
<Desc / Clms Page number 2>
The invention as characterized in the claims aims to remedy most of the drawbacks.
The principle is different in that there is no static tension on the walls of the holes. The traction force is distributed over several rods or arms anchored in the mass at a determined angle relative to the central traction screw. As a result, the tensile force is distributed over a larger area in the mass.
According to the arrangement of the rods in relation to the central body, part of the tensile force can be transformed into torsional force in the mass, therefore the anchoring depth will be greatly reduced compared to existing principles for the same force. traction.
The invention is set out below in more detail with the aid of drawings representing only two embodiments.
Figure 1 shows a front view showing a cylindrical body (1) with a hole (2) in the center in which is placed a tension screw (3). In the cylindrical body (1) there are three oblique holes (4) which start from the upper surface at a determined angle and end in the lower surface of the cylindrical body. The upper part of the holes (4) is slightly larger in diameter. In these holes are pushed three rods (5) which on one side have an enlargement of their diameter forming a head; fully pushed the head of the rods fits into

the widened part of the holes and comes to lock flush with the upper surface 0 of the body.
A washer (6) with a diameter +/- equal to the diameter of the body (1) is placed on the central screw which after tightening the assembly will prevent the rods from going up.
EMI2.2
Fig. (2) shows a different conception of the principle.
ZD There is no central body and the assembly consists of several parts (7) superimposed like arms. These parts have a rod or JD profile which terminates on a flat part (8) pierced with a hole in the center (9). The angle between the flat part and the rod is determined from the job and the 2D e

material in which it will be used. The arms are stacked on top of each other with an angular offset. tD The lower arm (10) has an internal thread (M) in the central part which will receive the traction screw (12). The other arms have the thinner flat part which forms a sharp angle (13) between the lower surface of the arm and the rod. Therefore the arm will press on the side of the previous arm at the time of traction.
After stacking the arms (usually three or more) the upper part of the last comes flush with the surface of the wall. Then place a washer (14) before tightening the assembly.

Operation of the anchoring system.
First mode of anchoring.
EMI4.1
We drill a hole Fig. 3 (15) using a bell-shaped tool Fig. 3 ZD t> (16) at a depth equal to the height of the cylindrical body with a diameter slightly less than the diameter of the body, then the body is driven out with the tension screw in the center in the cavity. Then we drill with

a drill bit having a diameter slightly less than the diameter of the rods 0 Z> through the holes in the body to a depth equal to the length of the rods. After which we push the rods through the holes Z> C> in the body in the mass to the bottom; finally we will place the washer on the traction screw and the assembly is ready for fixing an object.
Second anchoring mode.
As in the first case, a cavity is drilled in the mass with a tool. In this cavity we introduce a drilling template through which we will drill holes in the mass. The drilling template is removed and the first arm with a thread is introduced into the lower hole of the cavity and then the others. When the arms are installed, the traction screw is introduced through the holes in the arms to the thread in the lower arm and the assembly is ready to receive the object to be fixed.
