Description

Description de l'invention La présente invention concerne un dispositif de guidage pour la construction des angles et de la verticalité des murs maçonnés réalisés en agglo, béton, briques, pierres, 5 blocs à bancher etc. La construction de mur est toujours réalisée sur une assise béton en place (fondation ou dalle) sur laquelle on aura tracé l'implantation de l'ouvrage à réaliser. L'une des tâches la plus délicate de la construction des murs maçonnés est l'édification des angles afin d'obtenir une verticalité et un alignement parfaits de chaque 10 pan de mur. Traditionnellement pour réaliser cette tâche, l'ouvrier applique au droit de chaque angle de l'ouvrage à réaliser, un lit de mortier sur lequel il pose un agglo qu'il règle soigneusement à l'aide du fil à plomb pour obtenir une verticalité parfaite sur les 2 faces extérieures de l'agglo. 15 Après avoir posé un agglo à chaque angle du bâtiment, l'opérateur fixe un cordeau côté extérieur en partie haute des agglos d'angle pour les relier ensemble. Ce cordeau sert de guide pour la première rangée d'agglos. Pour les rangées suivantes, il renouvelle l'opération à chaque rangée d'agglo qu'il superpose jusqu'au sommet de la construction. 20 Avec le dispositif de l'invention proposé, on procède de façon suivante : Après le traçage de l'implantation des murs, on pose au droit de chaque angle du bâtiment un mat métallique vertical d'une hauteur d'étage d'environ 3 mètres sur lequel on accroche le cordeau qui donne l'alignement des rangées d'agglo. La stabilisation du mat à sa base est assurée par la pose préalable au sol d'un sa-25 bot métallique d'angle (Fig. C) équipé d'un manchon vertical sur lequel vient s'emboiter la partie inférieure du mat vertical. La stabilisation haute du mat vertical est assurée par 2 jambes de forces (Fig. B rep.4) qui sont fixées en partie basse sur 2 sabots secondaires (Fig. D), posés au sol et en partie haute sur 2 équerres métalliques solidaires du mat. 30 Le réglage et le blocage final de l'ensemble du dispositif est obtenu par des serre- joints à vis solidaires des équerres du mat en partie haute et des sabots secondaires en partie basse. Un mat vertical étant posé à l'extérieur de chaque angle de la construction, il suffit de les relier par un cordeau pour donner l'alignement et permettre la pose des agglos. 35 Pour faciliter la pose du cordeau, on a placé sur toute la hauteur d'une face du mat des têtes cle vis à espace régulier (tous les 10 cm environ) qui permettent le blocage du cordeau à la tension désirée. Description of the Invention The present invention relates to a guiding device for the construction of angles and verticality of masonry walls made of agglo, concrete, bricks, stones, 5 boulders etc. The wall construction is always carried out on a concrete base in place (foundation or slab) on which one will have traced the implantation of the work to be carried out. One of the most delicate tasks in the construction of masonry walls is the construction of angles in order to achieve perfect verticality and alignment of each section of wall. Traditionally to achieve this task, the worker applies to the right of each corner of the work to be done, a bed of mortar on which he places an agglo that he carefully adjusts with the help of the plumb line to obtain a perfect verticality on the 2 outer faces of the agglo. After placing a block at each corner of the building, the operator fixes a cord on the outer side at the top of the corner bells to connect them together. This cord serves as a guide for the first row of agglos. For the following rows, he renews the operation with each row of agglo which it superimposes to the top of the construction. With the device of the proposed invention, the following procedure is carried out: After the tracing of the implantation of the walls, a vertical metal mat is placed at the right of each corner of the building with a floor height of about 3 meters on which one hangs the cord which gives the alignment of the rows of agglo. The stabilization of the mat at its base is ensured by the prior laying on the ground of a sa-25 metal bot angle (Fig C) equipped with a vertical sleeve on which comes to fit the lower part of the vertical mat. The high stabilization of the vertical mast is ensured by 2 force legs (Fig. B rep.4) which are fixed in the lower part on 2 secondary shoes (Fig D), placed on the ground and in the upper part on 2 metal brackets integral with the mast. The adjustment and final locking of the entire device is achieved by screw clamps secured to the brackets of the mat in the upper part and secondary shoes in the lower part. A vertical mat is placed outside each corner of the construction, it is sufficient to connect them with a cord to give the alignment and allow the installation of the agglos. In order to facilitate the laying of the cords, regular-spaced screw heads (approximately every 10 cm) have been placed over the entire height of one side of the mat to allow the cord to be locked at the desired tension.

Le dispositif selon l'invention est un assistant de guidage de la verticalité des murs particulièrement destiné à l'industrie du bâtiment pour la construction des murs agglos, briques, blocs à bancher, pierres de toute nature et toutes épaisseurs. The device according to the invention is an assistant for guiding the verticality of the walls, particularly intended for the building industry, for the construction of walls, bricks, boulder blocks, stones of all kinds and all thicknesses.

Les figures A à D représentent un dispositif d'assistance du maçon pour obtenir la verticalité des parois lors de la construction des murs agglos, béton, parpaings, briques, blocs à bancher, pierres, etc. Ce dispositif se caractérise par la pose à chaque angle de l'ouvrage à réaliser, d'un mat vertical de guidage 1 (Fig. B) maintenu et stabilisé par 5 piè- 15 ces indépendantes reliées entre elles (Fig. A). Le dispositif se caractérise par un mat métallique 1 (Fig. B) de section carré d'une hauteur de 3 m environ, sur lequel on aura soudé 2 équerres 1 a (Fig. B) décalées de 10 cm, placées au 2/3 de la hauteur du mat et posé un manchon 1 b (Fig. B) en prolongation 20 de l'extrémité haute du mat pour éventuellement recevoir un deuxième mat pour l'étage supérieur. Le dispositif se caractérise par la fixation sur les 2 équerres 1 a (Fig. B) d'un serre- joint à vis monté sur un plat vertical soudé sur la partie horizontale de l'équerre. Le serre-joint à vis a pour but de bloquer la jambe de force 4 (Fig. B) en partie haute. 25 Le dispositif se caractérise par la fixation sur toute la hauteur d'une face du mat vertical d'une rangée de vis 1c (Fig. B) posées à intervalles réguliers de 10 cm environ. Ces têtes de vis ont pour but de bloquer le cordeau de guidage 5 (Fig. A) après tension de celui-ci. Le dispositif se caractérise par un sabot d'angle métallique (Fig. C) composé d'une 30 équerre à plat (Fig. C, rep.1) sur laquelle est soudé dans l'axe de l'angle un manchon vertical 2 (Fig. C) qui vient recevoir et bloquer le mat vertical d'angle. Pour stabiliser le sabot, on a fixé sous la face inférieure aux trois extrémités de l'équerre 3 tétons 3 (Fig. C) sur lesquels sont concentrées les charges, ce qui permet d'éviter le glissement du sabot sur le sol. L'ensemble de ce dispositif est destiné à régler précisément et stabiliser à sa base le 35 mat vertical d'angle. Le dispositif se caractérise par 2 sabots secondaires identiques (Fig. D) composés des éléments suivants : - 1 fer plat de base (Fig. D, rep.1), section 15/60 longueur 50 cm avec 2 barrettes 10/10/60 (Fig. D rep.2) soudés aux extrémités inférieures et qui reposeront sur le sol. Sur l'une des extrémités supérieures du fer sera fixé un manchon (Fig. D) destiné à recevoir le mat vertical d'angle dans le cas de réalisation d'angles obtus ou aigus. - Perpendiculairement sur le fer plat, on vient fixer un cadre 3 (Fig. D) de 17 cm X 17 cm en fer plat de 8/60. L'aile verticale de ce cadre (côté opposé au fer plat horizontal de base) sera prolongée dans sa partie supérieure de 150 mm, et de 25 mm dans sa partie inférieure. - Sur l'aile horizontale supérieure du cadre on aura soudé un fer plat vertical (Fig. The attached drawings illustrate the invention: Figure A represents the whole device seen in plan (Figure 1/10) Figure B shows the whole device seen from the front (Figure 1/125) Figure C represents the angle shoe seen in plan and seen in profile (Diagram 1/2) Figure D shows the secondary shoe seen in profile equipped with the serration system (Diagram 1/2). Figures A to D show a support device of the mason to obtain the verticality of the walls during the construction of the walls agglos, concrete, blocks, bricks, boulders, stones, etc. This device is characterized by laying at each angle of the work to be carried out, a vertical guide mat 1 (Fig B) maintained and stabilized by 5 independent parts connected together (Fig A). The device is characterized by a metallic mat 1 (Fig. B) of square section with a height of approximately 3 m, on which 2 brackets 1 a (Fig. B) offset by 10 cm, placed 2/3 of the height of the mat and placed a sleeve 1b (Fig. B) in extension 20 of the upper end of the mat to possibly receive a second mat for the upper floor. The device is characterized by the fixing on 2 brackets 1 a (Fig. B) of a screw clamp mounted on a vertical plate welded to the horizontal part of the square. The screw clamp is intended to block the strut 4 (Fig B) in the upper part. The device is characterized by fixing the entire height of a face of the vertical mat of a row of screws 1c (Fig. B) laid at regular intervals of about 10 cm. These screw heads are intended to block the guide cord 5 (Fig A) after tension thereof. The device is characterized by a metal angle shoe (FIG C) consisting of a flattened bracket (FIG C, rep.1) on which is welded in the axis of the angle a vertical sleeve 2 (FIG. Fig. C) which receives and locks the vertical corner mat. In order to stabilize the shoe, the 3 ends 3 (Fig. C) on which the loads are concentrated are fastened under the lower face to the three ends of the bracket, thus preventing the sliding of the shoe on the ground. The entire device is intended to precisely adjust and stabilize at its base the vertical corner mat. The device is characterized by 2 identical secondary shoes (Fig D) composed of the following elements: - 1 basic flat iron (Fig D, rep.1), section 15/60 length 50 cm with 2 bars 10/10/60 (Fig D ref.2) welded to the lower ends and resting on the ground. On one of the upper ends of the iron will be fixed a sleeve (Fig D) for receiving the vertical angle mat in the case of realization of obtuse or acute angles. - Perpendicularly on the flat iron, one comes to fix a frame 3 (Fig. D) of 17 cm X 17 cm in flat iron of 8/60. The vertical flange of this frame (opposite to the horizontal flat iron basic) will be extended in its upper part of 150 mm, and 25 mm in its lower part. - On the upper horizontal flange of the frame we will have welded a vertical flat iron (Fig.

D, rep.4) de 120 mm de longueur distant de 35 mm de l'aile extérieure du cadre. En partie haute de ce fer plat vertical on viendra fixer un serre-joint à vis horizontal traversant (Fig. D, rep.5). Dans les étages, pour fixer l'ensemble du dispositif contre le bâtiment, il est prévu au centre des plats verticaux du cadre, 2 trous de 19 mm de diamètre pour pouvoir fixer le 15 sabot à l'aide d'une tige filetée 6 (Fig. D) traversant le mur et bloquée à l'aide d'écrous à ailettes.
