Definitions

  • the present invention relates to a method of assembling an opening member of a thermal breaker metal joinery, and more particularly to such a method comprising a step of assembling an inner metal profile to a metal profile outside the door. using at least one assembly strip of thermally insulating material.
  • the document FR 2861764 has proposed a solution to this problem, which consists in providing the inner or outer body of the amount comprising the inner and outer profiles, of a material different from that of the outer or inner body respectively, to allow a reduction of the differential expansion between the inner and outer bodies.
  • EP 0 931 901 which relates to a frame structure, such as a window frame, facade structure or the like, lying in a plane, composed of lengths of profiles and comprising an outer frame to be fixed to a construction, the outer frame being divided by dormers and cross members fixed or fixed in section in which plate-shaped elements, glazing type, can be mounted.
  • Some sleepers and possibly also some of the dormant amounts are fixed in the outer frame and are provided with clamping means extending therethrough, adopting the form of clamp type clamping means, including prestressing bars which traverse a set of sections and lengths sleepers / dormant constituting the entire frame structure, aiming to increase the static strength of this structure.
  • a bar is introduced into each of the inner and outer profiles of a plurality of aligned thermal break profiles constituting the dormant structure.
  • the prestressing bars are tightened on the sides at the ends of the frame structure.
  • the present invention proposes a solution that addresses the problem of differential expansion of a thermal break profile constituting an opening amount of a metal joinery, improving the technologies of the prior art, notably offering possibilities of use and additional application.
  • the invention firstly relates to a method of assembling an opening amount of a metal joinery thermal break, comprising a step of assembling an inner metal section to a profile external metal using at least one assembly strip of thermally insulating material, constituting said opening, characterized in that it further comprises a step of applying a compressive prestressing force exclusively to the outer metal section between two longitudinally spaced points of said outer metal profile and engaged therewith.
  • the outer metal section constituting the opening amount which is the hot section in the case where essentially raises the problem of the invention, sees its expansion decrease, as well as the bending of the amount.
  • all the thermally conductive profiles of the upright can be made of a single material.
  • the prestressing further generates on the outer metal section a bending torque opposing its bending under the effect of thermal expansion.
  • the invention also relates to a device for implementing the method described above, this device comprising a tie rod capable of exerting the compression prestressing force to the outer metal profile, said tie rod having its ends fixed in two points. longitudinally spaced from the outer metal section.
  • said tie rod is generally disposed in a plane parallel to the plane of the outer metal profile, at a certain distance from the side opposite to that of the assembly bars and the inner metal profile, so that the prestressing force compression applied by the tie rod generates on the outer metal profile a bending torque opposing its bending under the effect of thermal expansion.
  • the device according to the invention may comprise means for adjusting the compressive prestressing force applied by the tie rod.
  • the tie rod may in particular comprise a thread at at least one of its ends, the means for adjusting the compression prestressing force comprising at least one adjustment nut cooperating with said threading to adjust the tension exerted on the tie rod between its points. fastening to the external metal profile.
  • the tie rod may be mounted between two fasteners secured to the outer metal section at said two points longitudinally spaced from said profile, said at least one adjusting nut being supported on one of said fasteners.
  • Said external metal section may comprise a part tubular of which said fasteners form end plugs.
  • said tie rod passes through an orifice formed in at least one guide bearing on said outer metal profile, said orifice having its axis offset from the fastening points of the tie rod to the outer metal profile, at a distance the opposite side to that of the assembly bars and the inner metal section.
  • FIG. 1 and 2 an opening amount of a metal joinery thermal break, for example a sliding sash amount, comprising an inner metal section 1 and an outer metal section 2 assembled by crimping in a conventional manner with the aid of two bars 3 in insulating material.
  • the inner metal section 1 is for example a conventional section of known type, as well as the insulating strips 3 used.
  • a tube 4 is made here in one piece with the outer metal section 2 outside the latter, that is to say on the side opposite to that of the assembly bars 3 and the inner metal section 1.
  • This tube opens in the example behind the ends of the section 2, as shown in FIG. figure 1 for example, to allow housing the cap 5 and the nut 8 between one end of the tube 4 and the end corresponding profile 2.
  • the tube 4 is closed at each of its ends by a plug 5.
  • Each plug 5 is pierced with an orifice 6.
  • the orifices 6 are traversed by a threaded rod 7 advantageously fixed by nuts preferably brakes 8 screwed with interposition of a washer 9 on the ends of the rod protruding from the plugs 5.
  • the plugs 5 are preferably partially embedded in the tube 4 and bear in opposition to each other on their respective ends of the tube 4, in order to be able to provide a reaction to the nuts 8 causing a tension of the threaded rod under the effect of the screwing of these nuts.
  • the body of the threaded rod 7 is further engaged in two threaded orifices 10 respectively formed in two guides 11, in the example, slidably mounted inside the tube 4.
  • the axes of the orifices 10 are offset with respect to the axes of the attachment points of the tie rod to the outer metal section 2, by a certain distance d , towards the side opposite to that of the assembly bars 3 and the inner metal profile 1, as represented on the figure 5 .
  • the threaded rod 7 is bent with its concavity inward.
  • the guides 11 are screwed onto the threaded rod 7 until they are respectively positioned in two predetermined positions as a function of the bending moment. sought as explained below, the rod then being engaged in the tube 4 by sliding.
  • the plugs 5 are placed in abutment on the ends of the tube 4 and the nuts 8 are screwed onto the ends of the rod 7.
  • the screwing of the nuts 8 causes compression prestressing in the outer section 2.
  • the degree of screwing therefore determines the adjustment of this prestressing.
  • This setting makes it possible to adapt the amount to a specific geographical environment essentially conditioned by the external temperature range to which the outer profile is subjected.
  • the nuts 8 can be hidden from view by a hood or the like (not shown) as needed.
  • the bending of the threaded rod 7 causes the arching effect, when the rod is put under tension, to press the guides 11 onto the outer profile 2, in the direction of the inner profile 1, and 3.
  • This support generates on the outer profile 2 a bending torque which opposes the bending caused by the temperature differential between the inner and outer metal profiles 1 and 2.
  • the positioning of the guides 11 on the threaded rod 7 allows the adjusting this couple.
  • the metal sections 1 and 2 are made of aluminum alloy and the steel rod 7, the compressive stress and the bending torque in the outer section 2 increase with the temperature difference between the inner metal profiles. and outside. Indeed, the coefficient of expansion of aluminum is nearly twice that of steel, so the invention allows an adaptation to the circumstances of its use.
  • the prestressing also makes it possible to envisage a threaded rod made of a material similar or identical to that of the inner and outer metal profiles for example to lighten the entire amount.
