Abstract

The invention relates to a device with which it is possible to prevent the escape of laitance in the area of the vertical connections of the shuttering panels at the moment of the use and internal vibration of the concrete. The device consists of a rigid filling (3) supporting a flexible seal (5) which is fixed to the inside of the vertical stiffening element (2) integral with the end of the shuttering panel (1). The flexible seal (5) blocked in a vertical housing (4) formed by the filling (3) and the inner wing of the stiffening element (2) ensures a complete imperviousness once the connection has been made between two shuttering elements (1) situated in the same plane (the same form lining).

Description

La présente invention concerne un dispositif d'étanchéité qui permet d'éviter toute fuite de laitance (eau + ciment + fines) entre 2 élémentsjuxtaposés de banches de coffrages au moment du coulage d'ouvrages en béton. The present invention relates to a sealing device which makes it possible to avoid any leakage of milt (water + cement + fines) between 2 elements juxtaposed with formwork panels when pouring concrete structures.

Traditionnellement, les extrémités verticales d'éléments de banches de coffrage sont fixées bout à bout, de façon à obtenir la longueur de coffrage souhaitée. Traditionally, the vertical ends of formwork formwork elements are fixed end to end, so as to obtain the desired formwork length.

Le raccordement ainsi réalisé permet d'assurer une continuité de la planimétrie de l'assemblage mais laisse des interstices libres propices aux fuites de laitance. The connection thus produced makes it possible to ensure continuity of the planimetry of the assembly but leaves free interstices conducive to leakage of laitance.

Ces fuites de laitance favoriseront, au moment du coulage, une ségrégation du béton qui se traduira par un défaut de cohésion des agrégats ou un manque d'enrobage et un aspect du parement final laissant apparaître des cavités appelées communément nids de sable ou nids de gravier". These laitance leaks will promote, at the time of pouring, a segregation of the concrete which will result in a lack of cohesion of the aggregates or a lack of coating and an aspect of the final facing revealing cavities commonly called nests of sand or nests of gravel ".

Pourront subsister également des aspérités ou des coulures de ciment après le décoffrage.Asperities or cement runouts may also remain after formwork is removed.

Ces défauts d'aspect ou ces aspérités devront ensuite faire l'objet de reprises et d'utilisation d'enduits de surfaçage appropriés. These appearance defects or roughness must then be subject to recovery and use of suitable surfacing plasters.

Le dispositif selon l'invention vise a supprimer ces inconvénients. The device according to the invention aims to eliminate these drawbacks.

Il permet un serrage souple et étanche entre 2 éléments verticaux de banches de coffrage. Ce qui contribue, au moment de la mise en place du béton, à lui conserver toutes ses caractéristiques techniques et la totalité de ses composants, c'est-à-dire : eau, ciment, sable, graviers, adjuvants. It allows a flexible and tight clamping between 2 vertical elements of formwork formwork. This contributes, when placing the concrete, to keep all its technical characteristics and all of its components, that is to say: water, cement, sand, gravel, additives.

Le résultat après décoffrage est un aspect du parement lisse, uniforme et continu. The result after formwork removal is a smooth, uniform and continuous appearance of the facing.

Les moyens mis en oeuvre pour obtenir ce résultat sont les suivants
Les figures 1 et 2 représentent en coupe et en perspective le dispositif selon l'invention.The means used to obtain this result are as follows:
Figures 1 and 2 show in section and in perspective the device according to the invention.

En référence à ces dessins, le dispositif comporte une fourrure rigide (3) de hauteur égale au raidisseur (2) solidaire de l'about de banche de coffrage (1) dans lequel elle est encastrée. With reference to these drawings, the device comprises a rigid fur (3) of height equal to the stiffener (2) secured to the end of the formwork section (1) in which it is embedded.

Cette fourrure (3) comporte une engravure de section carrée (4) dans laquelle vient se bloquer un joint souple (5). This fur (3) has a square section etching (4) in which a flexible seal (5) is blocked.

Cette fourrure (3) est maintenue dans le raidisseur au moyen de fixations appropriées (6). This fur (3) is held in the stiffener by means of appropriate fasteners (6).

Cette fourrure comporte 2 chanfreins (7) qui lui permettent un encastrement parfait dans le profil du raidisseur (2).  This fur has 2 chamfers (7) which allow it to fit perfectly into the profile of the stiffener (2).

Le joint (5) est utilisé sous forme de cordon souple de section et de densité judicieusement choisies dans le commerce. The seal (5) is used in the form of a flexible bead of cross section and density judiciously chosen commercially.

Ce joint (5) caoutchouc ou de matière synthétique bloqué entre la fourrure (3) et l'aile intérieure du raidisseur (2) viendra s'écraser sur le joint (5) opposé et similaire équipant l'about d'un autre élément (1) de banche de coffrage muni du meme dispositif. This seal (5) rubber or synthetic material blocked between the fur (3) and the inner wing of the stiffener (2) will be crushed on the opposite seal (5) and similar equipping the end of another element ( 1) formwork formwork fitted with the same device.

La liaison mécanique des 2 éléments de coffrage (1) sera ainsi complètée par une liaison étanche assurée par le plaquage des joints (5). The mechanical connection of the 2 formwork elements (1) will thus be completed by a sealed connection provided by the plating of the joints (5).

Le dispositif selon l'invention peut être utilisé pour assurer l'étanchéité du coffrage d'ouvrages en bétons verticaux. The device according to the invention can be used to seal the formwork of vertical concrete structures.

Ce dispositif peut s'adapter sur différents types et formes de coffrages tels que : coffrages cintrés, coffrages glissants, coffrages standards. This device can be adapted to different types and forms of formwork such as: curved formwork, sliding formwork, standard formwork.

A titre d'exemple non limitatif, le dispositif aura des dimensions de l'ordre de 3 cm pour l'épaisseur et de 6 cm pour la largeur. By way of nonlimiting example, the device will have dimensions of the order of 3 cm for the thickness and 6 cm for the width.

La hauteur restant variable. The height remains variable.
