Abstract
Description
La présente invention concerne un dispositif de coffrage des
tiné à la réalisation de pilliers et linteaux en béton armé pour
la conception de petits ouvrages dans le domaine de la construc
tion.The present invention relates to a formwork device for
dedicated to the realization of pillars and lintels in reinforced concrete for
the design of small works in the field of construction
tion.
La conception de ces pilliers et linteaux est actuellement
pratiquée par des briques ou blocs creux, par des coffrages en planches, et pour linteaux en forme d'arcs, par des moules (fond
de coffrage) que le maçon doit compléter pour les joues. Ces
dispositifs n'offrent qu'une finition brute nécéssitant une
reprise des tableaux au mortier. Egalement sont proposés des
linteaux ou baies fabriqués en usine mais d'une manutention peu
aisée de par leur poids, ou des baies plus légères à parois
minces nécéssitant un coffrage supplémentaire pour les linteaux
et pilliers d'embrasures.The design of these pillars and lintels is currently
made by bricks or hollow blocks, by plank formwork, and for arched lintels, by molds (bottom
formwork) that the mason must complete for the cheeks. These
devices only offer a rough finish requiring a
resumption of the tables with the mortar. Also are offered
lintels or bays made in the factory but with little handling
easy by their weight, or lighter, walled bays
thin requiring additional formwork for lintels
and pillars of doorways.
Le dispositif selon l'invention, permet sur les lieux même la
réalisation de pilliers et linteaux de formes diverses : droit,
anse de panier, arc sur baissé, arcs divers, avec ou sans feuil
lure à volet ou moulure décorative. Ce dispositif permet d'obte
nir en une seule opération de coulage une baie complète.The device according to the invention allows on site even the
realization of pillars and lintels of various forms: right,
basket handle, bow on down, various arcs, with or without foil
lure with shutter or decorative molding. This device allows
in a single casting operation, complete a bay.
Les dessins annexés illustre l'invention
En réference à ces dessins, l'élement de base est constitué de
deux joues (1) identiques, d'un fond (3) et d'entretoises (4).The accompanying drawings illustrate the invention
In reference to these drawings, the basic element consists of
two identical cheeks (1), a bottom (3) and spacers (4).
Joues et fond, de préférence en contre-plaqué bakelisé of
frant trés peu d'adhérence au béton et, sur chant une bonne
resistance à la fléxion.Cheeks and bottom, preferably in bakelized plywood of
frant very little adhesion to concrete and, on edge good
resistance to bending.
Les joues (1) présentent dans la partie inferieure une rai
nure (2) longitudinale assurant la résistance à la poussée du
béton sur le fond (3) et ce sur toute la longueur du coffrage.The cheeks (1) have a spoke in the lower part
longitudinal strip (2) ensuring resistance to the thrust of the
concrete on the bottom (3) over the entire length of the formwork.
Pour les linteaux en forme d'arc (fig 4), le fond (3) sera réa
lisé avec un contre -plaqué postformable.For arched lintels (fig 4), the bottom (3) will be
made with postformable plywood.
L'entretoise (4) est une pièce de bois, présentant deux
entailles (5) identiques de quelques dixiemes de millimétres
plus faibles que l'epaisseur des joues (1).The spacer (4) is a piece of wood, presenting two
identical notches (5) of a few tenths of a millimeter
smaller than the thickness of the cheeks (1).
l'élasticité naturelle du bois permet, par enfoncement de ce
coincer sur le chant des joues (1) assurant parallelisme,
équerrage et maintien du coffrage.the natural elasticity of the wood allows, by driving in this
wedge on the edge of the cheeks (1) ensuring parallelism,
squaring and maintaining the formwork.
Le débordement des entretoises (4) sur le coté des joues (1)
permet la saisie de celles-ci et par pivotement (6) de faire
levier sur une arrête du fond de l'entaille (5) et facilite le
démontage. The overflow of the spacers (4) on the side of the cheeks (1)
allows the entry of these and by pivoting (6) to make
lever on a stop at the bottom of the notch (5) and facilitates the
disassembly.
Les entretoises étant identique pour l'ensemble des pilliers et linteaux d'une même épaisseur qu'il soit droit ou en forme d'arc pourront servir individuellement pour l'un ou l'autre des coffrages. The spacers being identical for all the pillars and lintels of the same thickness, whether straight or arched, can be used individually for one or other of the forms.
Les joues (1) et le fond (3) ont les quatre arrêtes légerement biseautées pour facilité le montage du coffrage. The cheeks (1) and the bottom (3) have the four slightly bevelled edges for easy assembly of the formwork.
A l'exterieur des coffrages pilliers pour embrasure (fig 5 et 6) un tasseau (9) sera fixé de part et d'autre des joues (1) assurant la rigidité des joues et permettra la fixation au mur (10) à l'aide des moyens traditionnels, serre-joints (11) ou chevillettes. Outside the pillar formwork for embrasure (fig 5 and 6) a cleat (9) will be fixed on both sides of the cheeks (1) ensuring the rigidity of the cheeks and will allow the fixing to the wall (10) to the using traditional means, clamps (11) or ankles.
Ce tasseau (9) dépassant le coffrage pillier en partie haute permettra la liaison avec le coffrage linteau (fig 5).This cleat (9) projecting from the pillar formwork in the upper part will allow the connection with the lintel formwork (fig 5).
A l'interieur des coffrages pilliers (fig 5) un liteau de forme trapézofdale (8) sera fixé sur une joue des coffrages. Inside the pillar formwork (fig 5) a trapezoidal form strip (8) will be fixed on one side of the formwork.
Cette sur-épaisseur par rapport au mur permettra la finition de celui-ci au mortier.This extra thickness compared to the wall will allow it to be finished with mortar.
Pour réalisation avec feuillure à volet (fig 2) un liteau (7) sera fixé sur la joue (1) ou le fond (3) de coffrage. Il sera pratiqué de la même façon pour une moulure décorative. For realization with shutter rebate (fig 2) a batten (7) will be fixed on the cheek (1) or the bottom (3) of formwork. It will be done in the same way for a decorative molding.
Montage d'un élément coffrage - Pose du fond (3) dans les rainures (2) des joues (1) et enfoncement des entretoises (4). Installation of a formwork element - Installation of the base (3) in the grooves (2) of the cheeks (1) and insertion of the spacers (4).
Mise en oeuvre (fig 5) - Pose de la première rangée de brique (10) de part et d'autre de la baie. Implementation (fig 5) - Installation of the first row of bricks (10) on either side of the bay.
- Pose des coffrage pilliers et fixation au brique (10) par serre-joints (11).- Installation of pillar formwork and fixing to the brick (10) by clamps (11).
- Pose du coffrage linteaux la liaison se faisant avec les tasseaux (9) et la pose d'une entretoise (4) dans l'angle formé par le pillier et le linteaux.- Installation of the lintel formwork, the connection being made with the battens (9) and the installation of a spacer (4) in the angle formed by the pillar and the lintel.
- Ces trois éléments de coffrage seront maintenu à l'aplomb et de niveau par moyens traditionnels (pieds droits).- These three formwork elements will be kept level and level by traditional means (straight feet).
- Pose des armatures métaliques (12) dans les coffrages.- Installation of metal reinforcements (12) in the formwork.
- Les coffrages serviront de guide à l'élévation des murs jusqu'au
niveau haut du coffrage linteau.- The formwork will serve as a guide for raising the walls to
high level of the lintel formwork.
- Fixation des coffrages pilliers sur la hauteur du mur (10) par serre-joints (11).- Fixing of pillar forms on the height of the wall (10) by clamps (11).
- Coulage de l'ensemble pilliers et linteaux en une seule opération. - Pouring of all pillars and lintels in a single operation.
Après prise du béton, le décoffrage sera pratiqué comme suit - Dépose des pieds droits et serre-joints, des entretoises pilliers, des joues de pilliers, des entretoises linteau, des joues du linteau, puis des fonds de coffrage. After setting the concrete, the formwork will be carried out as follows - Removal of straight feet and clamps, pillar struts, pillar cheeks, lintel struts, lintel cheeks, then formwork bottoms.
Réalisation d'une arcade (fig 7 et 8) avec pillier isolé. Creation of an arcade (fig 7 and 8) with isolated pillar.
Pour ce type de pillier les joues (1) présentent deux rainures une de chaque coté, et recevront deux fonds (3) ou cotés (fig 8), la liaison des trois coffrages sera réalisée par une plaque de contre-plaqué (13) fixé sur les joues de part et d'autre des coffrages. For this type of pillar the cheeks (1) have two grooves, one on each side, and will receive two bottoms (3) or sides (fig 8), the connection of the three forms will be carried out by a fixed plywood plate (13) on the cheeks on either side of the formwork.
