Abstract

The invention concerns a simple arrangement, which takes up little space, can be completely recovered and permits assembly and alignment of panels, which can be simple shuttering boards. It consists of flat truss rods 1 inserted between two rows of panels 7, tubular spreaders 2, external bars 3, clamping wedges 4 and alignment bars 5 clamped by brackets 6 on the heels 8 of the truss rods 1. The shuttering is put into position in successive rows of panels. This arrangement is intended in particular for the construction of walls made of shuttered concrete, even if the accessibility of this wall is limited to only one of its faces for work to be carried out along embankments or other obstacles.

Description

La présente invention concerne un dispositif réutilisable permettant d'assembler et d'aligner des panneaux pour réaliser essentiellement des coffrages de -murs en béton banché.The present invention relates to a reusable device for assembling and aligning panels to essentially produce shuttering of walled concrete walls.

les dispositifs actuels sont constitués de pièces qui, après bétonnage, sont perdues dans le mur : brevets 2 364 314, 2 250 352, 1 218 366 ou encore n'intègrent pas un dispositif d'alignement des coffrages : brevet 1 515 261, tous nécessitant, au moins pour le démontage des coffrages, l'accès de l'ouvrier de chaque côté du mur.current devices consist of parts which, after concreting, are lost in the wall: patents 2 364 314, 2 250 352, 1 218 366 or even do not incorporate a formwork alignment device: patent 1 515 261, all requiring, at least for the dismantling of the forms, the access of the worker on each side of the wall.

Le dispositif selon l'invention, permet de remédier à ces inconvénients.The device according to the invention overcomes these drawbacks.

Il comporte, en effet, un tirant en fer plat (1) qui s'insère entre les panneaux (7) et dont l'épaisseur suffisamment faible, crée entre les panneaux un interstice suffisamment étroit pour que le béton ne coule pas en dehors des coffres au moment de sa mise en oeuvre. Ce tirant traverse un tube entretoise (2) qui cale les panneaux sur leur face intérieure.Ce tube, d'un diamètre intérieur égal à la largeur du tirant, reste donc centré sur cet organe pour assurer de façon égale la buttée des panneaux inférieur et supérieur. Une gaine en papier fort (non représentée sur le dessin) entoure le tube pour faciliter son extraction après bétonnage. le calage des faces extérieures des panneaux est assuré par deux barres '(3) règnant sur toute la hauteur du mur et qui traversent des trous ménagés dans les tirants à l'emplacement des faces extérieures des coffrages. Un coin fendu (4) chevauchant le tirant côté talon assure, en s'appuyant sur la barre, le serrage des panneaux inférieur et supérieur sur le tube entretoise (2)
L'alignement des panneaux est réalisé par un profilé (5) règnant sur toute la hauteur du mur et serré sur les talons (8) des tirants (1) par colliers à vis (6) ou serre-joints.It comprises, in fact, a flat iron tie (1) which is inserted between the panels (7) and whose sufficiently small thickness, creates a sufficiently narrow gap between the panels so that the concrete does not flow outside the safes at the time of its implementation. This tie rod crosses a spacer tube (2) which holds the panels on their inner face. This tube, with an inner diameter equal to the width of the tie rod, therefore remains centered on this member to ensure the abutment of the lower panels equally and superior. A strong paper sheath (not shown in the drawing) surrounds the tube to facilitate its extraction after concreting. the outer faces of the panels are wedged by two bars' (3) prevailing over the entire height of the wall and which pass through holes made in the tie rods at the location of the outer faces of the forms. A split wedge (4) overlapping the heel side pulling ensures, by pressing on the bar, the tightening of the lower and upper panels on the spacer tube (2)
The alignment of the panels is achieved by a profile (5) prevailing over the entire height of the wall and tightened on the heels (8) of the tie rods (1) by screw collars (6) or clamps.

les panneaux (7) peuvent être des planches de coffrage. leur montage est réalisé par lits successifs formés de deux panneaux de hauteur égale, 1 'ouvrier n'ayant besoin pour le faire que d'accède d'un seul côté du mur. De même, pour le démontage effectué par desserage des coins (4) qui libèrent les barres extérieures (3) s'enlevant alors par glissement depuis et vers le haut du mur. Les tirants (1) à leur tour libérés s'extrayent vers la face accessible du mur, leur talon (8) ayant été positionnés de ce côté au montage. L'extraction des panneaux placés sur la face non accessible peut être alors réalisé depuis le sommet du mur à l'aide de crochets.the panels (7) can be formwork boards. their mounting is carried out by successive beds formed by two panels of equal height, the worker only needing to do so to access on one side of the wall. Similarly, for the disassembly carried out by loosening the corners (4) which release the external bars (3) then being removed by sliding from and up the wall. The tie rods (1) in turn released are extracted towards the accessible face of the wall, their heel (8) having been positioned on this side during assembly. The extraction of the panels placed on the inaccessible side can then be carried out from the top of the wall using hooks.

Ce dispositif, selon l'invention, est essentiellement destiné à la réalisation de murs en béton banché. This device, according to the invention, is essentially intended for the production of walled concrete walls.
