Definitions

the present invention relates to the field of construction, in particular to the realization of devices for insulating in the event of thermal breakage 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 structure 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 device consists of a rigid or quasi-rigid insulating plate traversed by reinforcing bars also called concrete bars, preferably protected against corrosion, at least in line with the passage in the insulating element.
the bars are anchored in the structural elements on either side of the insulating element. The device is placed so that the insulating element is 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.
this insulating material is not sufficiently resistant, the positioning of the bars requires to add 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).
this insulating material 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 or he may suffer damage.
a possible solution is to provide stainless steel only for a reduced length on each side of the insulation and to weld a complement of traditional carbon steel bar.
This advantageous device in terms of the cost of production is however related to the quality of the weld, precisely in the zone where the force is maximum and presents a risk of corrosion related to the formation of oxides during welding.
the consequences of a faulty weld or corrosion can be dramatic in the case of hanging a balcony, since breaking a bar will cause an overload of the next bar that may not resist.
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.
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 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 aims to provide a solution for a device that provides insulation during easy transport and for the protection of the insulating material.
Another object of the present invention is to provide an element which limits the length of the reinforcing bars preferably made of stainless steel in order to maintain 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.
An essential characteristic of the invention lies in the actual design of the product in that it produces a non-deformable box or cage which serves as a support for the reinforcing bars necessary for stability and which can be filled with an insulation of any type to meet thermal, acoustic and / or fire resistance requirements.
the present invention relates to a device for providing thermal break insulation in the form of a building element, comprising an insulating material to be disposed in a substantially longitudinal direction between two building parts, and reinforcing bars (4,6) passing through the insulating material, characterized in that the device comprises a profile in the form of a box or a cage (1,3) open or closed and which defines a internal space (7) in which is disposed said insulating material.
said box or said cage has at least in a transverse section a rectangular periphery completely closed and has the essential shape of a rectangular parallelepiped.
the profile intended to make said box or said cage has characteristics of rigidity or crush resistance.
the profile is made of a metallic or polymeric material.
said cage or said box comprises at least two distant surfaces arranged longitudinally opposite and intended to maintain at least the upper face and the lower face of the box or cage.
the two opposite upper and lower surfaces are connected by spacers or walls.
the upper and lower surfaces are solid or perforated.
the side walls of the box are solid or perforated.
the thickness of the cage or the box is calculated according to the choice of insulating material filling the space constituted by said cage or said box.
the side walls of the box have orifices allowing the passage of reinforcing bars or their accessories.
straight bars or slashes pass through said box.
the device comprises at least one obliquely diagonally arranged slash and the dimensions of said box or of said cage are calculated in such a way that the elbows or radii of curvature of the obliquely diagonally arranged slash are found outside the internal space .
the device comprises a sleeve or an intermediate part making it possible to assemble two parts of current reinforcing bars, said sleeve or said intermediate part being placed directly within said box or said cage.
said sleeve has in its central part a section reduction.
the sleeve is provided with an external relief.
the sleeve has at its ends inner ropes so as to receive the threaded ends of the reinforcing bars.
the sleeves are sleeves for producing straight or oblique bars.
the figure 1 describes the general principle underlying the invention.
the figure 1 schematically describes in a sectional view a device which implements the principle according to a first aspect of the present invention.
an essential feature of the invention is the presence of a rigid box or rigid cage equipped with reinforcing bars or other parts to ensure the stability of the structures, said box or said cage being able to be filled with a insulating material of any kind according to the requirements of each particular application.
Reinforcing bar means reinforcement bars intended to be poured into the concrete adjacent to the insulating element.
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 fiber elements or resin.
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 may have a completely closed periphery.
the box or the cage has in at least the 4 directions perpendicular to the longitudinal direction of the completely closed walls, with the exception of openings intended for the passage of reinforcing bars or their accessories.
the box or cage if it is further closed on its last two faces, that is to say on the six faces so as to make a closed space in the form of a parallelepiped, one could even consider the use of insulating material in granular form, fibrous or even in the form of gel or foam that could be injected or even poured into the closed space.
the box or cage may be partially open or have partially perforated walls.
the box or cage comprises two continuous profiles, the first upper (1) and the second lower (2) held at a distance by spacers (3) preferably punctual to form a box or cage relatively rigid or dimensionally stable which are fixed bars upper armature (4), lower (5) and diagonally (6).
the free space (7) 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 figure 3 shows a second preferred version of the product according to the invention.
the upper part of the box or cage is composed of three distinct profiles, two lateral profiles (8) and (9) surmounted by a cover (10).
the lower part is composed of two lateral profiles (11) and (12) and a cover (13).
the lateral parts are held at a distance by spacers (3) to stiffen the box or cage.
the upper (4), lower (5) and diagonal (6) bars are attached to the lateral profiles (8), (9), (11, and (12) and are therefore in no way supported by the insulation that fills the cavity (7) inside the box or cage.
the upper and lower parts may not be continuous and leave openings, as well as the lateral spacers could be continuous to form solid walls on each side of the insulation. All combinations are possible and the examples given to figures 2 and 3 are not limitations of the invention. At the extreme, the box could be completely closed on its periphery or widely open on all sides. Finally, the bars represented are not a limitation, they are elements of stability and their presence or shape depends on the efforts to be transmitted. Similarly the constituent material is not a limitation, the term "steel reinforcing bar" is used for a preferred form of the invention, but any other material for transmitting the forces can be envisaged.
a "sleeve” which passes through the thickness of the insulation and therefore the thickness of the box or cage.
the rebar will either be threaded or pressed.
the “sleeve” is advantageously as an intermediate piece or interlayer between 2 reinforcing bars.
the sleeve may have a certain relief to prevent the possible progression of the water towards the bars attaching to the ends.
the figure 4 shows an example of a long sleeve (10) according to a preferred form of the invention.
the ends (20) are worked to mechanically fasten common concrete bars (30).
the central zone (40) may advantageously have a section reduction to reduce heat flow and a certain relief (50) may be marked to stop a possible flow of water.
the figure 5 shows explicitly an embodiment using a sleeve according to the invention.
An insulating plate (60) preferably rigid or semi-rigid, possibly enclosed in an indeformable cage, is traversed by a long sleeve (10).
This sleeve is preferably made of steel and is protected against corrosion. It has a section reduction (40) in the passage of the insulating material (60) to reduce heat losses. Bars (30) are mechanically attached to the ends of the sleeve.
the sleeve may further be advantageously provided with relief (50) intended to prevent the possible progression of the water towards the bars (30) which are not protected against corrosion.
the figure 6 shows an example of a sleeve (10) according to the invention.
the mechanical joint is made by a thread (70) on the bars (30) which will overlap with the bars of the adjacent structures and by an internal thread (80) in the sleeve (10) compatible with those made on the bars.
the outer relief (50) is also shown in a preferred form, but could have any other form according to the invention.
the figure 7 shows two embodiments of the invention when the bars are not in the same alignment, for example oblique or diagonal.
the Sleeves (9a) and (9b) may have any profile, for example a bend or bend (100) for connecting the two bars (11) and (12) at an angle.
the characteristic elements according to another aspect of the invention are the following: it is a device for mechanically assembling two common bars by a sleeve protected against corrosion.
the sleeve is advantageously provided with a section reduction in its central part and preferably provided with a certain external relief.
the sleeve is provided with internal threads at its ends.
An important advantage of the present invention is to provide a fully equipped metal preferring profile that can be transported to the job site.
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 performed on site and aimed at fixing the reinforcing bars on the sleeves and to introduce if it has not already been made the insulating material within the cage or box.
the material will be chosen insulation so as to ensure that the thickness of the box or cage is not too high and allows the radii of curvature of elbows slant or diagonally arranged along said box or cage are located outside thereof.
