Abstract

The invention consists in assembling with one another, by sealing with synthetic resin 4, the three elements which usually constitute a floating pontoon: the structure 1, the flooring 2, the floats 3. By varying the width of the flooring and the number of floats from zero to three, 3 different modules are obtained - pontoon, catway, gangway - which can be combined with one another for making jetties, ports, landing stages, pontoons.

Description

L'invention consiste à assembler entre eux, d'une manière irréversible, par scellement aux résines synthétiques, les éléments constitutifs d'un ponton flottant. The invention consists in assembling together, in an irreversible manner, by sealing with synthetic resins, the components of a floating pontoon.

Traditionnellement, les pontons sont réalisés, soit de manière provisoire par un assemblage hétéroclite de planches, bastaings et fAts métalliques, soit par des structures lourdes boulonnées ou soudées à la demande et nécessitant des volumes de flottaison importants. Traditionally, pontoons are made, either temporarily by a heterogeneous assembly of planks, bastaings and metal beams, or by heavy structures bolted or welded on demand and requiring large flotation volumes.

L'invention permet de disposer d'un ensemble homogène de modules combinables entre eux, démontables, extensibles, réutilisables et dont le poids de l'élément le plus lourd est inférieur à 90 kg.  The invention makes it possible to have a homogeneous set of modules which can be combined together, which can be dismantled, extended, reused and whose weight of the heaviest element is less than 90 kg.

La figure 1 représente en coupe transversale grandeur nature le détail d'assemblage. Figure 1 shows a life-size cross section of the assembly detail.

La figure 2 représente en coupe longitudinale le détail de fixation des flotteurs. Figure 2 shows in longitudinal section the attachment detail of the floats.

Deux poutres creuses en Aluminium de section 100 x 50 et de longueur 3000 (1) supportent un platelage discontinu (2) constitue de 25 éléments d'un profile d'Aluminium de section 100 x 18 préalablement rempli, soit de mousse de polyuréthane, soit de mortier de résine synthétique pour en assurer la rigidité. A chaque extrémité un profilé identique (5) sert de renfort bas. Two hollow aluminum beams of section 100 x 50 and length 3000 (1) support a discontinuous decking (2) consisting of 25 elements of an aluminum profile of section 100 x 18 previously filled, either with polyurethane foam or synthetic resin mortar to ensure rigidity. At each end an identical profile (5) serves as a bottom reinforcement.

Tous ces éléments sont percés puis assemblés à l'aide de 100 boulons poeliers de 10 x 100, à raison de 2 boulons par élément de platelage (6). All these elements are drilled and then assembled using 100 10 x 100 door bolts, at the rate of 2 bolts per decking element (6).

Des anneaux d'amarrage et de fixation (7) traversent les poutres à intervalles réguliers. Mooring and fixing rings (7) pass through the beams at regular intervals.

On obtient ainsi à l'intérieur des profilés une véritable armature comparable aux armatures de béton armé et qui joueront le même rôle. There is thus obtained inside the profiles a real reinforcement comparable to reinforcements of reinforced concrete and which will play the same role.

Après serrage modéré des boulons et des anneaux, les poutres sont remplies par gravité avec un mortier de résine formulé à partir de résine de synthèse convenablement catalysée, de micro-ballons de verre et de fibres d'amiante longues (4). After moderate tightening of the bolts and rings, the beams are filled by gravity with a resin mortar formulated from suitably catalyzed synthetic resin, glass micro-balloons and long asbestos fibers (4).

Ce mortier coulable présente, après durcissement, une densité de 0,6 pour une résistance à la compression supérieure à 600 kgZcm2 à 24 heures de séchage. This pourable mortar has, after hardening, a density of 0.6 for a compressive strength greater than 600 kgZcm2 at 24 hours of drying.

Après prise du mortier de résine, les profilés flotteurs en acier prélaqué à chaud sont remplis de mousse de polyuréthane, aux 5 de leur volume, serrés sur les boulons existants par l'intermédiaire d'une contre-plaque, puis rigidifiés par le coulage du mOrne mortier de résine. After setting the resin mortar, the hot prepainted steel float profiles are filled with polyurethane foam, at 5 of their volume, tightened on the existing bolts by means of a counter plate, then stiffened by pouring the resin resin mortar.

En faisant varier la largeur du platelage et des renforts bas et le nombre de flotteurs de zéro à trois, on dispose de trois modules différents dont une passerelle d'accès sans flotteur.  By varying the width of the decking and bottom reinforcements and the number of floats from zero to three, we have three different modules including an access bridge without float.

L'assemblage de ces modules entre eux en tous sens et toutes dimensions permet de composer des ensembles flottants très variés qui trouveront une application dans les Travaux Publics et Maritimes, pour la construction ou l'entretien d'ouvrages b la mer, dans l'Agriculture, pour la réalisation de centres d'aquaculture ou de trottoirs flottants sur maré- cages et marigots, dans les Loisirs enfin pour la réalisation de miniports, jetées ou appontement.  The assembly of these modules together in all directions and all dimensions makes it possible to compose very varied floating assemblies which will find an application in Public and Maritime Works, for the construction or maintenance of works at sea, in the Agriculture, for the construction of aquaculture centers or floating sidewalks on swamps and backwaters, in Leisure, finally for the construction of miniports, jetties or wharf.
