Definitions

• the invention relates to extruded light alloy profiles, in particular aluminum alloy, which can be assembled laterally by clipping to one or two other profiles. These profiles are intended, in particular, for the construction of load-bearing structures, for example beams or floors of buildings or industrial or railway vehicles, or tail lifts of industrial vehicles.
• European patent EP 0825062 (Peter Maierchtbau) describes the lateral assembly of profiles, intended in particular for the manufacture of tail lifts for trucks, comprising on one side face a longitudinal bead in relief, and on the other side face a longitudinal groove intended to receive the bead of the neighboring profile.
• the bead is fixed in the corresponding groove by welding with filler metal.
• the invention aims to allow the realization of load-bearing structures by lateral assembly of extruded light alloy profiles, using a simple, rapid and economical assembly technique both by the assembly time and the absence of significant investments, while ensuring high mechanical strength and perfect assembly security. Subject of the invention
• the subject of the invention is a light alloy extruded section, able to be assembled laterally to another section, comprising either at least one longitudinal bead in relief, or at least one longitudinal groove of complementary section, either one and the other. 'other, characterized in that the section of the bead and that of the groove are conical in shape and provided with notches with a negative clearance.
• the invention also relates to a method of lateral assembly of two profiles of this type comprising the introduction of the bead of the first profile into the groove of the second and the clipping of the two profiles by applying pressure to the right of the bead, in particular at using a press brake or roll forming machine.
• FIG. 1 shows, in section perpendicular to the length, a tailgate floor for a truck lift using the assembly according to the invention.
• Figure 2 shows, also in section perpendicular to the length, a profile according to the invention used in the manufacture of a beam.
• Figure 3 shows, in enlarged view, the assembly area of two profiles according to the invention once assembled.
• the light alloy extruded profiles according to the invention intended for large load-bearing structures are generally hollow multi-chamber profiles such as those shown in FIGS. 1 and 2. These profiles comprise, in known manner, at least one longitudinal bead (1) serving as a male part for assembly, or a groove (2), also longitudinal, serving as a female part, in which the bead enters during assembly.
• the profiles may include one or more beads (1) and / or one or more grooves (2) depending on whether one wants to assemble them to one or two other profiles.
• the particularity of the invention lies in the shape of the section of the bead (1) and that, complementary, of the groove (2) shown in Figure 3. Indeed, both have a conical section with a series of notches (3).
• the slope of the cone is preferably between 5 and 20%.
• the clearance between the bead (1) and the groove (2) is negative, that is to say that the conical section of the bead (1) is slightly wider than that of the groove (2). This negative clearance is advantageously between 2 and 10% of the width of the groove (2).
• the bead (1) is positioned opposite the groove (2).
• the profile carrying the notched conical groove advantageously has an approach slope, for example a lip (4) as shown in FIG. 3.
• the pressure required for assembly must be adjusted, a pressure that is too low leading to incorrect mounting with docking and alignment faults, too high a pressure which could damage the notches (3) and therefore weaken the seizure and create play.
• This pressure can be implemented by machines that frequently exist in metal construction workshops, such as a press brake or a roll forming machine, which most often avoids additional investments.
• the press brake comprises an assembly table, pneumatic or hydraulic cylinders and a bar transmitting the force, which can go up to 1 ton per linear meter.
• the assembly is carried out in advance, either with a single train of rollers, but passing twice, or with two trains of rollers.
• the assembly according to the invention makes it possible to make two or more sections integral with one another without loss of mechanical characteristics in the connection zone, and thus to constitute a load-bearing structure homogeneous to the resistance to the forces to which it is subjected.
• a single assembly between two sections is sufficient to provide the necessary mechanical strength. It is thus possible to produce a tail lift for a truck of length 1700 mm and width 2400 mm by lateral assembly of 9 sections of length 2400 mm and width 188 mm.
• This tailgate can withstand bending fatigue under a load of 15,000 N applied to the cantilevered end of 1,700 mm relative to the attachment to the vehicle.
• Beams can also be produced with the profiles according to the invention by lateral assembly of profiles of the type shown in FIG. 2, which represents a central profile assembled on both sides.
• FIG. 2 represents a central profile assembled on both sides.
• the assembly time is greatly reduced and no rework such as grinding, machining or cleaning is necessary after assembly. Performed with appropriate pressure, the assembly offers excellent safety, while preserving the lightness of the structure.
