Abstract

The equipment supports the shuttering when pouring concrete on profiled dam planks as used in waterworks, e.g. a reinforced quay wall. The concrete is supported by one or more components rigidly clamped in position at the sides inside the recesses of the planks, and in the lengthwise direction of the dam wall. There can be a single such component, extending horizontally, and the clamping devices can be adjustable, being actuated mechanically, pneumatically, hydraulically or electro-magnetically, with remote control.

Description

L'invention concerne un appareil de support et de maintien des parois d'un coffrage destiné à recevoir le béton pour former une poutre contre ou sur la partie supérieure d'un rideau de palplanches présentant un profil creux ouvert avec des ailes, telles que des palplanches à profil trapézoïdal.The invention relates to an apparatus for supporting and holding the walls of a formwork intended to receive concrete to form a beam against or on the upper part of a sheet pile wall having an open hollow profile with wings, such as sheet piles with trapezoidal profile.

Il est courant de couler une poutre de béton horizontale au sommet d'un rideau de palplanches. Pour ce faire, on soude en général des cornières ou des tiges métalliques sur les parois verticales de certaines palplanches et ces cornières ou tiges métalliques constituent des supports pour le bois de coffrage lequel s'inscrit donc également dans les parties creuses du rideau de palplanches. Dans le coffrage ouvert à sa partie supérieure on dépose les armatures de renforcement de la poutre de béton. Lorsque ce dernier a fait prise, le bois de coffrage est récupéré et les éléments de support du coffrage, constitués par les cornières et les tiges métalliques soudées aux palplanches, doivent être découpés au chalumeau.It is common to pour a horizontal concrete beam on top of a sheet pile wall. To do this, generally metal angles or rods are welded to the vertical walls of certain sheet piles and these metal angles or rods constitute supports for the formwork wood which therefore also fits into the hollow parts of the sheet pile wall. In the formwork open at its upper part, the reinforcement reinforcements of the concrete beam are deposited. When the latter has set, the formwork wood is recovered and the formwork support elements, consisting of angles and metal rods welded to the sheet piles, must be cut with a torch.

Dans DE-A-24 15 013 on a déjà proposé, dans le même but, de soutenir les éléments de coffrage à l'aide de dispositifs de présentant sous la forme d'un cadre fermé, sauf à la partie qui vient prendre appui de parta et d'autre du rideau de palplanches, c'est-à-dire à la partie inférieure du dispositif. Tous les éléments de coffrage étant soutenus par des pièces s'adaptant en hauteur ou en largeur prennent appui sur ledit cadre. Quoique ce dispositif constitue un progrès évident dans l'établissement d'un coffrage d'une poutre au sommet d'un rideau de palplanches, il présente l'inconvénient de ne pas laisser un accès libre sur la partie supérieure de toute la longueur du coffrage.In DE-A-24 15 013 it has already been proposed, for the same purpose, to support the formwork elements with the aid of devices having the form of a closed frame, except for the part which comes to rest on from both sides of the sheet pile curtain, that is to say at the bottom of the device. All the formwork elements being supported by parts that are adapted in height or in width bear on said frame. Although this device constitutes an obvious progress in the establishment of a formwork for a beam at the top of a sheet pile wall, it has the disadvantage of not leaving free access to the upper part of the entire length of the formwork. .

L'invention a pour but de remédier à ces inconvénients et de proposer un appareil présentant des moyens de fixation sur un seul côté de chaque palplanche formant le rideau dans le but de garantir un accès libre au-dessus de coffrage.The object of the invention is to remedy these drawbacks and to propose an apparatus having fixing means on one side of each sheet pile forming the curtain in order to guarantee free access above the formwork.

A cet effet, l'appareil selon l'invention comporte sur deux côtés opposés des moyens de blocage latéral sollicités en compression, situés à la base de l'appareil et sous le coffrage de la poutre à réaliser, lesdits moyens étant réglables au moins d'un côté et susceptibles de prendre appui sur les parois internes des deux ailes opposées, dans le creux d'une palplanche, pour maintenir ledit appareil à une hauteur déterminée sur la palplanche.To this end, the apparatus according to the invention comprises on two opposite sides lateral locking means urged in compression, located at the base of the apparatus and under the formwork of the beam to be produced, said means being adjustable at least d 'one side and likely to bear on the internal walls of the two opposite wings, in the hollow of a sheet pile, to maintain said device at a determined height on the sheet pile.

D'autres détails et avantages de l'invention résulteront de la description que sera donnée ci-apres, à titre d'exemple, d'un appareil de support et de maintien des parois d'un coffrage, selon l'invention. Les notations de référence se rapportent aux figures ci-annexées.

  • La figure 1 montre deux appareils disposés de part et d'autre d'un rideau de palplanches.
  • La figure 2 montre selon une vue en plan schématique, deux appariels selon l'invention et montés dans deux palplanches adjacentes.
Other details and advantages of the invention will result from the description which will be given below, by way of example, of an apparatus for supporting and holding the walls of a formwork, according to the invention. The reference notations refer to the appended figures.
  • Figure 1 shows two devices arranged on either side of a sheet pile curtain.
  • Figure 2 shows in a schematic plan view, two devices according to the invention and mounted in two adjacent sheet piles.

Chaque appareil est constitué d'une plaque (1) présentant d'une manière générale la forme d'un trapèze correspondant à la forme du creux d'une palplanche à profil trapézoïdal utilisée pour former un rideau. Le rideau de palplanches tel qu'il est constitué, est représenté schématiquement à la figure 2, présente pour chaquement palplanche une base rectiligne constituant le fond de la palplanche et deux ailes (2') et comprend des moyens de blocage latéral sollicités en compression de telle sorte que chaque appareil peut être bloqué indépendemment dans le creux d'une palplanche et cela chaque fois, pour chaque élément, d'un côté de rideau de palplanches, laissant ainsi un accès libre au-dessus du coffrage destiné à former une poutre au sommet des palplanches.Each device consists of a plate (1) generally having the shape of a trapezoid corresponding to the shape of the hollow of a sheet pile with trapezoidal profile used to form a curtain. The sheet pile wall as it is constituted, is shown diagrammatically in FIG. 2, has for each sheet pile a straight base constituting the bottom of the sheet pile and two wings (2 ′) and comprises lateral locking means urged in compression from so that each device can be blocked independently in the hollow of a sheet pile and each time, for each element, on one side of the sheet pile wall, thus leaving free access above the formwork intended to form a beam at top of sheet piles.

Les moyens de blocage dont est équipé l'appareil doivent être au moins et au choix:

  • - 1 saillie et 2 tourillons réglables,
  • - 2 saillies et 1 tourillon réglable,
  • - 1 saillie, 1 tourillon réglable et une équerre dirigée vers le bas.
The locking means with which the device is fitted must be at least and optionally:
  • - 1 projection and 2 adjustable pins,
  • - 2 projections and 1 adjustable pin,
  • - 1 projection, 1 adjustable pin and a square directed downwards.

En se référant une nouvelle fois à la figure 2 on constatera que chaque appareil de support et de maintien des parois d'un coffrage présente d'un côté deux saillies coniques (3) et de l'autre deux tourillons réglables (4), munis également d'extrémité conique.Referring again to Figure 2 we see that each device for supporting and holding the walls of a formwork has on one side two conical projections (3) and the other two adjustable pins (4), provided also of conical end.

Le sens des flèches (6) et (7) illustrent schématiquement les mouvements qui peuvent être imprimés au tourillon conique (4) pour les bloquer contre la paroi interne (2') d'une aile ou, au contraire, pour débloquer l'appareil en écartant l'extrémité du tourillon conique de l'aile (2').The direction of the arrows (6) and (7) schematically illustrate the movements which can be printed on the conical pin (4) to block them against the internal wall (2 ') of a wing or, on the contrary, to unlock the device. by spreading the end of the conical pin of the wing (2 ').

Il est évident qu'on pourrait également ne prévoir qu'un tourillon conique (4) par appareil coopérant avec une saillie (3). Dans ce cas il faut prévoir un moyen qui s'oppose au basculement de l'appareil. Ce moyen est contitué par une équerre (8) qui, en position d'utilisation vient appuyer contre la palplanche considérée. Cette équerre, est fixée à un bras (9) qui, en position d'utilisation de l'appareil s'étend horizontalement. Ce bras (9) porte également un autre bras (10) monté coulissant sur le premier bras (9) et qui est destiné à retenir un élément de coffrage vertical (11), comme le montre la figure 1.It is obvious that one could also only provide one conical pin (4) per device cooperating with a projection (3). In this case it is necessary to provide a means which opposes the tilting of the device. This means is formed by a square (8) which, in the position of use presses against the sheet pile considered. This bracket is fixed to an arm (9) which, in the position of use of the device extends horizontally. This arm (9) also carries another arm (10) slidably mounted on the first arm (9) and which is intended to retain a vertical shuttering element (11), as shown in Figure 1.

De la description qui vient d'être donnée d'une appareil de support et de maintien des parois d'un coffrage selon l'invention, il résulte que chaque appareil se monte très aisément dans le creux d'une palplanche à profil trapé- zoidal tout en maintenant entièrement libre l'accès par le dessus ou coffrage.From the description which has just been given of a device for supporting and holding the walls of a formwork according to the invention, it follows that each device is very easily mounted in the hollow of a sheet pile with trapezoidal profile. while maintaining completely free access from above or formwork.

L'invention n'est évidemment pas limitée à la forme d'exécution décrite ci-dessus et que bien des modifications pourraient y être apportées sans sortir du cadre de la présente demande de brevet, l'étendue de la protection étant déterminée par la teneur des revendications.The invention is obviously not limited to the embodiment described above and that many modifications could be made to it. Without going beyond the scope of this patent application, the scope of protection being determined by the content of the claims.
