Definitions

  • the present invention relates to the field of construction, in particular to the realization of devices and accessories intended to provide insulation in the event of thermal breaks mainly in case of interruption in the insulation of buildings in general.
  • the problems related to thermal bridges caused mainly by the interruption of the insulation at the junctions of external structures are well known in the field of construction.
  • the devices intended to reduce these heat losses generally consist in ensuring the continuity of the thermal insulation by interposition of an insulation traversed only by point elements of metal structure which ensure the transmission of the forces (shearing force and bending moment).
  • the insulation element comprises a rigid or quasi-rigid insulating plate traversed by reinforcing bars, preferably protected against corrosion, at least to the right of the passage in the insulating element.
  • the bars are anchored in the structural elements on either side of the insulating element.
  • the element is laid in such a way that the insulation board either in the extension of the current insulation of the building, whether external or internal to the supporting structure.
  • this relatively rigid plate is made of a material that has characteristics that not only provide the required thermal, fireproof and acoustic insulation performance and correspond to the specifications but also serves as support for the reinforcing bars.
  • Reinforcing bars are reinforcement bars intended to be poured into the concrete adjacent to the insulating element. As a result, these bars are also called concrete bars. They are usually made of steel, if possible stainless steel, but it is of course possible to consider using new particularly resistant materials, such as rods of polymeric material fiber or resin.
  • the bars are arranged and are dimensioned to take the bending moment by a pull-compression torque in the upper and lower horizontal bars that equip the device.
  • a difficulty is to maintain the right distance between these bars not to change the forces in the bars by changing the lever arm.
  • Spreading the bars leads to reduce the coating, bringing them together increases the efforts in the bars.
  • this insulating material is not strong enough, the positioning of the bars requires adding mounting bars or other complicated devices that can also hinder the implementation when the elements are intended to integrate into a denser reinforcement (beams for example).
  • the insulating material constituting the plate is relatively fragile, it can crumble especially around its periphery as the edges, for example, which will occur more often than the device is actually prefabricated in the workshop and must be transported on site where he may suffer damage.
  • the present invention is advantageously aimed at finding a solution to the problem of the state of the art and in particular to overcome the various disadvantages described above.
  • Another object of the present invention is to provide an element which limits the length of the corrosion-protected reinforcing bars, for example to keep the advantage of the reduced cost, by mechanically joining the current bars to eliminate the risk associated with welding while reducing the number of parts to be assembled and therefore the cost of assembly.
  • the present invention aims to provide a solution that does not use the strength of the insulating plate as a support for the proper placement of rebar.
  • the present invention also aims to provide a solution that allows to choose the appropriate insulation only according to its thermal, fire and / or acoustic characteristics without having to check the stability characteristics of said plate.
  • the present invention relates to a device for effecting the junction within an insulation element between two bars or parts of bars reinforcement, characterized in that it is in the form of a sleeve or insert to assemble the two or both parts of reinforcing bars by a mechanical assembly.
  • the length of the sleeve is greater than the thickness of the insulation member.
  • said sleeve has in its central part a section reduction with respect to the section of its two ends.
  • the diameter of the central portion of the sleeve corresponds essentially to the diameter of the adjacent reinforcing bars.
  • the sleeve is provided with an external relief.
  • the sleeve has at its ends an internal thread so as to receive the threaded ends of the adjacent reinforcing bars.
  • the sleeve has a bend so as to allow the placement of an oblique reinforcing bar.
  • the sleeve is made of stainless steel or a material coated with an anticorrosive material.
  • an additional characteristic of the invention lies in the actual design of the product and in particular of the insulating element in that it is embodied in the form of a box or an essentially indeformable cage which serves Reinforcing bar support required for stability and can be filled with insulation of any type to meet thermal, acoustic and / or fire resistance requirements.
  • Box or cage means a rigid non-deformable element which defines the space in which the insulating material is enclosed. This also means that in at least one sectional view, the profile of the box or the cage can / must have a completely closed periphery.
  • the present invention therefore also relates to a device for insulating in case of thermal break in the form of a construction element, comprising an insulating material to be arranged in a substantially longitudinal direction between two building parts, and reinforcing bars which pass through the insulating material, characterized in that the device comprises a profile in the form of a box or an open or closed cage and which defines an interior space in which said material is disposed insulation, the reinforcing bars being interconnected within the same insulating material via a device as described above.
  • said box or said cage has at least in a cross section in the longitudinal direction a substantially rectangular completely closed rectangular periphery and the essential shape of a rectangular parallelepiped.
  • the profile for producing said box or said cage has characteristics of rigidity and / or crush resistance so that it is essentially indeformable.
  • the profile is made of a metallic or polymeric material.
  • said box or said cage comprises at least two distant surfaces arranged longitudinally opposite and intended to provide at least the upper face and the lower face of said box or said cage.
  • these two opposite surfaces forming the upper and lower faces are connected by spacers or side walls.
  • the upper and lower faces may be solid or perforated while the side walls of said box or said cage may also be solid or perforated.
  • the thickness of said box or said cage corresponding to the dimension is calculated according to the choice of the insulating material filling the interior space of said box or said cage.
  • the side walls of said box or said cage have orifices allowing the passage of the reinforcing bars and / or their accessories and in particular sleeves.
  • straight bars or slashes pass through said box or said cage.
  • the device comprises at least one oblique bar disposed diagonally in a perpendicular plane.
  • the dimensions of said box or said cage are calculated so that the elbows or radii of curvature of the slant disposed diagonally are found outside the internal space of said box or said cage.
  • the Figures 1a and 1b describe the complete device for insulating a wall in case of thermal breakage in two embodiments.
  • FIGS 2 to 5 describe several examples of embodiments of sleeves usable within an insulation element and allowing the joining of adjacent reinforcing bars ( Figures 2 to 4 ) both rectilinear and Figures 5a and 5b ).
  • FIGS. 1a and 1b schematically describe a sectional view of an isolation device which implements the principle according to the present invention.
  • a rigid or semi-rigid insulation element 7 is equipped with reinforcing bars 20, 30 or other parts to ensure the stability of the structures.
  • a box or a rigid cage essentially indeformable 10 is present and is equipped with reinforcing bars 20, 30 or other parts to ensure the stability of said structures, said box or said cage being filled with an insulating material 107 of whatever it may be according to the requirements of each particular application.
  • the reinforcing bars external to the insulating material are interconnected by a sleeve 10 which passes through the thickness of the rigid, semi-rigid or non-rigid insulation throughout this thickness.
  • the assembly of the reinforcing bars with the sleeve is carried out by a mechanical assembly.
  • Mechanical assembly means an assembly that does not require the use of an adhesive or a specific treatment, only the shape of the ends is adapted to allow the joining.
  • a mechanical assembly must be opposed to a chemical or thermal assembly which requires the presence of a chemical agent such as glue or adhesive or heat treatment such as welding.
  • the mechanical assembly offers the advantage of being able to allow, if necessary, the separation to facilitate transport and installation but especially reduces the risk of corrosion.
  • this mechanical assembly can be made by threading.
  • Another embodiment makes it possible to envisage clipping of different elements and in particular of one end of a sleeve with one end of a reinforcing bar.
  • This sleeve 10 is therefore advantageously in the form of an intermediate piece or interlayer which serves as a junction between two successive reinforcing bars 20, 30 made in a conventional manner.
  • the nature of the sleeve is such that it is protected against corrosion and it will advantageously be made of stainless steel or of a polymeric material, for example fiber or resin. According to another alternative, it will be coated with an anticorrosive coating.
  • the sleeve has in its central portion a reduced section relative to its ends.
  • this reduced section also makes it possible to reduce heat flows and thus allow better insulation by reducing heat losses.
  • Another interesting feature of the present invention lies in the fact that said sleeve has on its outer surface a relief.
  • This relief may have any shape and is intended essentially to stop a possible path of water that would promote some corrosion.
  • this relief is achieved by the presence of grooves on the outer surface of said sleeve.
  • the figure 2 shows an example of sleeve 10 according to a preferred form of the invention.
  • the ends 11, 12 are worked to mechanically fasten concrete concrete bars 20, 30.
  • threading, clipping or interlocking complementary elements may be considered.
  • the central zone 14 advantageously has a section reduction to reduce the heat flows.
  • a certain relief 15 may be provided to stop a possible flow of water.
  • Reduction of section simply means that the section is weaker in the center of the sleeve than at the ends. According to a first conventional embodiment, it is sufficient that the diameter of the sleeve is substantially of the order of the diameter of the adjacent bars while the ends of course have a larger diameter for securing to said bars.
  • the figure 3 shows explicitly an embodiment using a sleeve according to the invention.
  • An insulating element 7 or 107 preferably rigid or semi-rigid or possibly enclosed in an indeformable cage 10, is traversed by a sleeve 10.
  • This sleeve is preferably made of steel and is protected against corrosion. It presents a reduction of section 14 in the passage of the insulating material 100 or 107 to reduce heat loss.
  • Bars 20, 30 are mechanically attached to the ends of the sleeve.
  • the sleeve may also be advantageously provided with a relief 15, for example in the form of grooves, intended to prevent the possible progression of water to the adjacent bars 20, 30 which are not protected against corrosion.
  • the figure 4 in particular shows an example of sleeve 10 according to the invention.
  • the mechanical joint is made by a thread 21, 31 on each of the bars 20, 30 which will ensure contact with the ends of the sleeve 10, ends which have an internal thread 17, 18 compatible with that 21, 31 on the bars 20, 30.
  • the outer relief 15 is also shown in a preferred form, but could have any other form according to the invention.
  • the Figures 5a and 5b show two embodiments of the invention when the bars are not in the same alignment, for example oblique or diagonal.
  • the sleeves 19a and 19b may have any profile, for example a fold or a bend 13 for connecting the two bars 20 and 30 at an angle.
  • an additional characteristic of the invention lies in the actual design of the product and in particular of the insulating element in that it is embodied in the form of a box or an essentially indeformable cage which serves of rebar support necessary for stability and which can be filled with any type of insulation for meet the requirements for thermal, acoustic and / or fire resistance.
  • the box or the cage has in at least both directions perpendicular to the longitudinal direction of the walls completely closed with the exception of openings for the passage of reinforcing bars and / or their accessories.
  • said box or said cage is further closed on its last two faces, that is to say on the six faces so as to create a closed space in the form of a parallelepiped it could even be envisaged to use insulating material in granular, fibrous form or even in the form of a gel or foam that could be injected or even poured into the enclosed space.
  • the box or the cage may be partially open or have partially perforated walls.
  • the box or cage 100 comprises two continuous profiles, the first is an upper profile 101 and the second is a lower profile 102 which are held at a distance by spacers 103 preferably point or side walls 104 to form a box or a cage relatively rigid and indeformable where the rebar is fixed (upper, lower or diagonally).
  • the free space 107 inside the box or cage can be filled with a suitable insulating material, even without great rigidity, which best meets the requirements of each particular situation.
  • the upper and lower parts may not be continuous and leave openings, as the lateral spacers could be continuous for form solid walls on each side of the insulation. All combinations are possible and the examples given to figures 1 and 7 are not limitations of the invention. At the extreme, the box could be completely closed on its periphery or widely open on all sides.
  • the bars 20, 30 shown do not constitute a limitation, they are stability elements and their presence or shape depends on the forces to be transmitted. Similarly, the material constituting the sleeve and bars is not a limitation, the terms "steel reinforcing bar" are used for a preferred form of the invention, but any other material for transmitting the forces can to be considered.
  • An important advantage of the present invention is to provide a fully equipped metal preferring profile that can be transported to the job site. It may even be considered to include the insulating material and sleeves already properly arranged on site and not in the workshop as is currently the case. This will be particularly advantageous in the case of an insulating element in the form of granular material, fibrous or even in the form of gel or foam. Similarly, if such a device is equipped with a box or preferably metal cage and various sleeves directly attached to said cage or box, its transport will be greatly facilitated. The assembly is then carried out on site and aimed at fixing the reinforcing bars on the ends of the sleeves and to introduce if it has not already been made the insulating material within the cage or box.
  • the insulating material will be chosen so as to ensure that the thickness of the box or cage is not too high and preferably allows the radii of curvature of the elbows of the oblique bars or diagonally arranged according to said box or cage are located outside of it.
