Abstract
Description
Coffrage enveloppe pour ouvrage en béton
La présente invention concerne les types de coffrages permettant de réaliser des ouvrages en béton principalement sous forme de poutres ou de longrines soit en infrastructure soit en superstructure.Enclosure formwork for concrete structure
The present invention relates to the types of formwork making it possible to produce concrete structures mainly in the form of beams or beams either in infrastructure or in superstructure.
Dans des dispositifs-connus de ce genre, les divers types de coffrage sont constitués soit par des panneaux rigides en bois, métalliques ou autres matériaux, soit par des moules préfabriqués, soit réalisés sur place avec des planches. De tels dispositifs sont d'un emploi malaisé, lourds, longs et difficiles à mettre en oeuvre, nécessitant dans la plupart des cas un décoffrage et souvent imposant la création d'un enduit ou d'un ragréage pour obtenir un aspect fini de l'ouvrage coulé.In known devices of this kind, the various types of formwork are constituted either by rigid panels of wood, metal or other materials, or by prefabricated molds, or produced on site with boards. Such devices are difficult to use, heavy, long and difficult to implement, requiring in most cases a formwork and often requiring the creation of a coating or patching to obtain a finished appearance of the cast work.
Le coffrage enveloppe suivant L'inention permet d'éviter ces inconvénients.The following envelope formwork The invention avoids these drawbacks.
Il est en effet constitué en matière synthétique malléable, à la fois souple et rigide, résistante et inaltérable, débité sous forme de bande et pouvant etre mis en oeuvre intégralement aux dimensions du projet a réaliser; destiné à rester définitivement solidaire de 1' ouvrage coulé et présentant un aspect propre et fini.It is in fact made of malleable synthetic material, which is both flexible and rigid, resistant and unalterable, cut in the form of a strip and which can be used entirely to the dimensions of the project to be carried out; intended to remain permanently attached to the cast work and having a clean and finished appearance.
Selon une première variante, le coffrage enveloppe est constitué de deux joues et d'un fond.According to a first variant, the envelope formwork consists of two cheeks and a bottom.
Selon une deuxieme variante le coffrage enveloppe est constitué d'une single joue.According to a second variant, the envelope formwork consists of a single cheek.
Le dispositif selon l'invention permet de coffrer rapidement et défi nitivenent - des poutres en béton armé en superstructure - des longrines en béton en infrastructure
Le dessin annexé est une vue en plan avec coures des deux variantes.The device according to the invention makes it possible to quickly form and challenge nitivenent - reinforced concrete beams in superstructure - concrete beams in infrastructure
The accompanying drawing is a plan view with lines of the two variants.
Tel qu'il est représenté, la figure 1 est un tronçon de bande vue en plan de la première variante. Les joues 1 sont solidaires d'un fond 2. La jonction entre les joues 1 et le fond 2 est matérialisée par deux amorces de pliage 3 lesquelles amorces 3 sont renforcées par une armature 7 incorporée dans la r.iatière ( voir figure~4 suivant coupe B.B.). La fce intérieure des joues destinée à recevoir le béton comporte des ondes (voir figure 3 suivant coupe A.A.).As shown, Figure 1 is a strip section in plan view of the first variant. The cheeks 1 are secured to a bottom 2. The junction between the cheeks 1 and the bottom 2 is materialized by two folding primers 3 which primers 3 are reinforced by a frame 7 incorporated in the r.iatière (see figure ~ 4 next section BB). The inner face of the cheeks intended to receive the concrete comprises waves (see FIG. 3 following section A.A.).
Ces ondes destinées à raidir l'enveloppe pour résister à la poussée du béton pendant le coulage peuvent éventuellement être renforcée par des tiges métalliques 6 incorporées dans la matière (voir figure 3 suivant coupe A.A.)
Chaque extrémité des joues comporte un épaulement 4 avec trous 5 à intervales assez rapprochés. Ces trous sont destinés à recevoir des tiges métalliques préalablenent coudées 8 (figures 6 et 7 ) lesquelles tiges 8 maintiennent l'écartement.These waves intended to stiffen the envelope to resist the thrust of the concrete during pouring can possibly be reinforced by metal rods 6 incorporated in the material (see figure 3 according to section AA)
Each end of the cheeks has a shoulder 4 with holes 5 at fairly close intervals. These holes are intended to receive bent metal rods 8 previously (Figures 6 and 7) which rods 8 maintain the spacing.
La face extérieure des joues ou l'épiderme destinée à rester apparante peut présenter plusieurs aspects soit lisse ou de couleur pour éviter une application de peinture, soit avec un treillis métallique 9 en saillie (voir figure 7) pour recevoir l'adhérence d'un futur enduits
La figure 2 représente un tronçon de bande unitaire vue en plan pour l'application de la deuxième variante0
Cette bande comporte également des ondes 1 sur la face intérieure mais comporte deux épaulements 4 à chaque extrémité; ces deux épaulements 4 comportent également des trous 5 (voir figure 5 sui- vant coupe C.C.) pour recevoir les tiges métalliques d'écartement 8.The external face of the cheeks or the epidermis intended to remain visible can have several aspects either smooth or colored to avoid an application of paint, or with a metal mesh 9 projecting (see FIG. 7) to receive the adhesion of a future coatings
FIG. 2 represents a section of unitary strip seen in plan for the application of the second variant0
This strip also includes waves 1 on the inner face but has two shoulders 4 at each end; these two shoulders 4 also have holes 5 (see FIG. 5 following section CC) to receive the metal spacer rods 8.
La figure 6 représente la mise en oeuvre d'une poutre coulée en superstructure. On place la bande avec fond, coupée à la longueur désirée sur un étaiement il (lequel étaiement ne fait pas partie intégrante de l'invention)0 On place le ferraillage 10 de la poutre sur le fond 2. On rabat les joues il et on place les tiges métalliques coudées 8 dans les trous 5 des épaulements 4. La poutre est prête à être coulée.FIG. 6 represents the implementation of a beam cast in superstructure. We place the strip with bottom, cut to the desired length on a shoring it (which shoring is not an integral part of the invention) 0 We place the reinforcement 10 of the beam on the bottom 2. We fold the cheeks there and place the bent metal rods 8 in the holes 5 of the shoulders 4. The beam is ready to be cast.
La figure 7 représente la mise en oeuvre d'une longrine coulée sur le sol.Figure 7 shows the implementation of a sill cast on the ground.
On place deux joues maintenues parallèles par des tiges métalliques coudées 8 incorporées dans l'épaulement inférieur 4o On positionne l'armature 10 de la longrine0 On place ensuite la seconde joue puis les tiges dscartement 8 en partie haute. La longrine est prête à être coulée.Two cheeks are held held parallel by bent metal rods 8 incorporated in the lower shoulder 4o. The frame 10 of the sill is positioned. Next, the second cheek is placed, then the spacer rods 8 in the upper part. The sill is ready to be poured.
Le débit en bande permet d'obtenir des longueurs uniques sans joint. Dans le cas d'angle, la matière malléable peut être facilement découpée. La jonction se fait à l'aide de ruban adhésif. La hauteur des joues 1 et la largeur du fond 2 sont variables en fonction des sections désirées.The strip flow makes it possible to obtain unique lengths without joints. In the corner case, the malleable material can be easily cut. The connection is made using adhesive tape. The height of the cheeks 1 and the width of the bottom 2 are variable according to the desired sections.
Le dispositif, objet de l'invention, peut être utilisé dans tous les cas de réalisation d'ouvrages en béton armé particulièrement sous forme de poutres ou de longrines. The device, object of the invention, can be used in all cases of making reinforced concrete structures, particularly in the form of beams or beams.
Des applications particulièrement intéressantes peuvent être la réalisation rapide, finie et précise de poutres en béton ou de longrines sur puits pour la --fondation de maisons ou d'immeubles ou bien les soubassements pour les murs de clôture ou de maisons. Particularly interesting applications can be the rapid, finished and precise production of concrete beams or sills on wells for the foundation of houses or buildings or even the foundations for the walls of fences or houses.
