Description

Securing unit for securing load-bearing and thermal insulation elements to supporting structures
The subject of the invention relates to a securing unit for securing load-bearing and thermal insulation elements to supporting structures, which has a pulling pin, a griping cartridge provided with a gripping channel, a spherical hinge and a clamping disc, where the pulling pin has a tensioning cone located at the one end located towards the supporting structure and a tension unit pulled onto the pulling pin, furthermore the spherical hinge has a supporting surface, protrusion and a sleeve passing through the protrusion, the clamping cartridge is at least partially fitted into the sleeve of the spherical hinge, while the clamping disc is provided with a receiving surface corresponding to the supporting surface of the spherical hinge and a through-hole formed in the receiving surface, with the securing unit in its use position the protrusion of the spherical hinge is pushed through the through-hole of the clamping disc, and the supporting surface of the spherical hinge is connected to the receiving surface of the clamping disc, and the other end of the pulling pin opposite the one end provided with the tensioning cone is secured in the gripping channel of the clamping cartridge.
Modem passive homes require high-thickness thermal insulation elements, and it is only possible to secure external load-bearing elements to the supporting structure behind the thick thermal insulation using special solutions that usually create thermal bridges, i.e. fittings that pass through the thick thermal insulation. These external load-bearing elements secure the thick thermal insulation and the external surfacing, fittings, fitted in front of the thick thermal insulation. The thick thermal insulation is unable to support itself, the external surfacing and fittings. The essence of the known fittings used for fitting thermal insulation is that they contain a securing device linked to the supporting structure, a connection device adapted for supporting the thermal insulation element, and a preferably long bridging element linking these two devices that also passes through the thermal insulation element.
Such a solution is disclosed by, among others, Hungarian patent specification registration number 229 785. In the case of this design, the thermal insulation element is kept in place on the supporting structure by a clamping disc that has a roughened pulling pin that is secured with one or two wedges that open apart like scissors and a self-locking hinge element. The advantage of the solution is that the self-locking connection of the roughened supporting pin and the hinge element of the clamping disc makes it suitable for fixtures where the external plane of the thermal insulation element is not perpendicular to the plane of the supporting structure. Its disadvantage, however, is that the one or two wedges that open apart like scissors, due to their external, deformed surface, pushed apart by the conical end at the end of the pulling pin do not rest up against the wall of the bore in the supporting structure with their entire surface, and so the extent of the friction faces in contact with each other is insufficient for reliable fixing. Its other disadvantage is that the rough coating required on the pulling pin for it to be secured can only be created during production in an uneconomical way.
Publication document number WO 96/24732 relates to a securing unit that is adapted for retaining panelling mounted in front of a supporting structure. The disadvantage of this solution, however, is that it contains numerous components, the assembly and adjustment of are labour-intensive and also require specialist knowledge. It is also a deficiency of the design that it is not suitable for the securing of softer materials, such as thermal insulation panels.
The objective with the solution according to the invention is to overcome the deficiencies of the known securing units used for mounting thermal insulation onto supporting structures and to create a version that is simple to use, that may be fitted easily and quickly, and is also suitable for supporting surfacing systems on the facade surface of the supporting structure in addition to the weight of the thermal insulation elements using pulling pins that are designed to have an angled line of effect.
The objective with the solution according to the invention was to overcome the deficiencies of the known such securing units and to create a version that has a simple structure, is easy to handle and fit, and, as a result of its structural design, it creates a friction surface between the supporting structure and the tension unit of sufficient size that is capable of supporting the greater carried load, and, in addition it may also be manufactured at a favourable cost level.
The basis of the idea behind the invention was the recognition that if, contrary to the known solutions, the one end of the pulling pin connected to the clamping cartridge of the hinged clamping disc is left smooth, and if the inner surface of the clamping cartridge connected to the smooth end is provided with grips, and, furthermore, if at the other end of the pulling pin a snap-fixed tensioning cone is formed either from the material of the pulling pin or with a roughened internal bore, onto which a helically wrapped tape is applied as a tension unit in a novel way, then, on the one hand, the dual shaped end of the pulling pin may be formed simply, and, on the other hand, during the movement of the helically wrapped tape towards the inner end of the pulling pin due to the expansion of the helically wrapped tape on the tension unit the tensioning cone becomes seized in the diameter of the receiving bore over a large friction surface and so the task may be solved.
In accordance with the set objective, the securing unit for securing load-bearing and thermal insulation elements to supporting structures according to the invention, - which has a pulling pin, a clamping cartridge provided with a gripping channel, a spherical hinge and a clamping disc, where the pulling pin has a tensioning cone located at the one end located towards the supporting structure and a tension unit pulled onto the pulling pin, furthermore the spherical hinge has a supporting surface, protrusion and a sleeve passing through the protrusion, the clamping cartridge is at least partially fitted into the sleeve of the spherical hinge, while the clamping disc is provided with a receiving surface corresponding to the supporting surface of the spherical hinge and a through-hole formed in the receiving surface, with the securing unit in its use position the protrusion of the spherical hinge is pushed through the through-hole of the clamping disc, and the supporting surface of the spherical hinge is connected to the receiving surface of the clamping disc, and the other end of the pulling pin opposite the one end provided with the tensioning cone is secured in the gripping channel of the clamping cartridge, - is created in such a way that the surface of the gripping channel of the clamping cartridge is provided with grips, and with the securing unit in use position the grips are pushed into the material of the other end of the pulling pin and/or the tension unit pulled onto the pulling pin is formed by a helically wrapped tape, where the helically wrapped tape delimits a helical cavity, and with the securing unit in use position the tensioning cone of the pulling pin is at least partially in a position of being pulled into the helical cavity of the helically wrapped tape.
A further feature of the securing unit according to the invention may be that the pulling pin is made from plastic. In the case of another version of the securing unit, the clamping cartridge is made from metal, and the grips are formed by notches located on the inner surface of the gripping channel of the clamping cartridge, or the clamping cartridge is made from plastic, and the grips are formed by hard particles irregularly positioned on the inner surface of the gripping channel of the clamping cartridge.
In the case of yet another different embodiment of the invention the tensioning cone located at the one end of the pulling pin nearer to the supporting structure is made from the material of the pulling pin, and constitutes a single unit with it, or the tensioning cone located at the one end of the pulling pin nearer to the supporting structure is made from a metal, and is secured to the one end of the pulling pin with a force-locked joint and/or with a form-locked joint.
From the point of view of the securing unit it may be preferable if the material of the tension unit formed from helically wrapped tape is profiled tape.
The most important advantage of the securing unit according to the invention is that the pulling pin may be provided simply from a plastic, with minimal heat transmittance and a smooth surface, composite or stainless steel rods.
Another advantage of the solution is that the clamping cartridge with roughened face of the clamping disc and the helically wrapped tape delimiting the helical cavity take on the increasing tensioning demand applied during securing with the self-locking structure.
It is a further advantage that the pulling pin with angled line of effect to the facade plane of the supporting structure may be burdened with the force arising in the plane of the clamping disc while resting on the thermal insulation element.
Further details of the invention will be explained via exemplary embodiments with reference to figures, wherein:

Figure 8 shows a version of the securing unit according to the invention in use position.
Figure 1 shows a possible version of the one end la of the pulling pin 1 of the securing unit according to the invention, of the tensioning cone 3 located at the one end la, and of the tension unit 2 pushed onto the tensioning cone 3. Here the pulling pin 1 and the tensioning cone 3 are made from a single material, as a single unit. Both the pulling pin 1 and the tensioning cone 3 are made from high tensile strength plastic.
Now figure 2 illustrates how the tension unit 2 located on the tensioning cone 3 of the pulling pin 1 is created. It may be seen that the tension unit 2 is a helically wrapped tape 2a, which delimits the helical cavity 2b. In the interest of achieving this, in this case the helically wrapped tape 2a is a profiled metal tape. But it should be mentioned here that the helically wrapped tape 2a may also be made from plastic. Figure 2 also shows that with the securing unit in initial position the helical cavity 2b of the helically wrapped tape 2a of the tension unit 2 substantially follows the shape of the tensioning cone 3 at the one end la of the pulling pin 1.
Figure 3 shows the one end la of the pulling pin 1 and the tensioning cone 3 connected to it. In the case of this version the pulling pin 1 is high tensile strength plastic, and the tensioning cone 3 is made from metal. The grooved inner surface 3a is created in the tensioning cone 3. The one end la of the pulling pin 1 is pushed into this grooved inner surface 3 a, then when the tensioning cone 3 is compressed the grooves of the grooved inner surface 3a of the tensioning cone 3 become pressed into the surface of the one end la of the pulling pin 1, and in this way the force-locked and form-locked joint between the pulling pin 1 and the tensioning cone is created.
Moving now to figure 4, it shows a possible version of the clamping disc 7 located at the other end lb of the pulling pin 1 of the securing unit according to the invention, the spherical hinge 6 connected to it, and the clamping cartridge 4. It may be observed here that the clamping disc 7 has a spherical shell shaped receiving surface 7a, and a through- hole 7b created in the receiving surface 7a. The protrusion 6b of the spherical hinge 6 is placed in this through-hole 7b.
The protrusion 6b supports the supporting surface 6a and the sleeve 6c as well. The size and the shape of the supporting surface 6a corresponds to the receiving surface 7a of the clamping disc 7, and together the receiving surface 7a and the supporting surface 6a form a joint. The clamping cartridge 4 is fitted into the sleeve 6c of the protrusion 6b.
If should be noted here that the clamping disc 7, the spherical hinge 6 and the clamping cartridge 4 are known of in themselves from patent registration number HU 229785. The significant difference, however, is that the inner surface 4b of the gripping channel 4a of the clamping cartridge 4 made from metal material is provided with grips 4c. In the case of this version the grips 4c are formed by notches 5 a, which may be lateral ribs or even a screw thread.
Figure 5 shows the other end lb of the pulling pin 1 as it is pushed into the gripping channel 4a with its inner surface 4b roughened using notches 5a of the metal clamping cartridge 4 inserted into the sleeve 6c of the spherical hinge 6 resting on the receiving surface 7a of the clamping disc 7 in a universal joint manner, with the clamping cartridge in clamped state. In such a case the notches 5a of the clamping cartridge 4 become pushed into the shell surface of the other end lb of the pulling pin 1, and in this way maintains the pulling pin 1 in clamped position. With this essentially the clamping cartridge 4 creates a force-locked and form-locked joint between the clamping disc 7 and the pulling pin 1. Figure 6 shows another possible version of the clamping disc 7 located at the other end lb of the pulling pin 1 of the securing unit according to the invention, the spherical hinge 6 connected to it, and the clamping cartridge 4. It may also be seen here that the clamping disc 7 has a spherical shell section shaped receiving surface 7a, and a through-hole 7b created in the receiving surface 7a. The protrusion 6b of the spherical hinge 6 is placed in this through-hole 7b.
The protrusion 6b carries the supporting surface 6a and the sleeve 6c as well. The size and shape of the supporting surface 6a corresponds to that of the receiving surface 7a of the clamping disc 7, and together the receiving surface 7a and the supporting surface 6a form a joint. In addition, the clamping cartridge 4 is fitted into the sleeve 6c of the protrusion 6b. However, in the case of the given embodiment the clamping cartridge 4 is made from plastic, and the grips 4c on the inner surface 4b of the gripping channel 4a are from a hard material, e.g. hard particles 5b made from corundum.
Figure 7 depicts the arrangement according to figure 6 in fitted state. Here the other end lb of the pulling pin 1 pushed into the gripping channel 4a, with its inner surface 4b roughened with hard particles 5b, of the plastic clamping cartridge 4 inserted into the sleeve 6c of the spherical hinge 6 resting on the receiving surface 7a of the clamping disc 7 as a universal joint may be seen with the clamping cartridge 4 in clamped state. In this case the hard particles 5b of the clamping cartridge 4 become pushed into the shell surface of the other end lb of the pulling pin 1, and in this way that maintain the pulling pin 1 in clamped state. With this essentially the clamping cartridge 4 creates a force-locked and form-locked joint between the clamping disc 7 and the pulling pin 1..
A version of the securing unit according to the invention may be seen in figure 8 in installed state, where the pulling pin 1 has a planned angled line of effect. The one end 1 a of the puling pin 1 is pushed into the borehole 8a of the supporting structure 8, and the helically wrapped tape 2a used as tension unit 2 is already pushed onto the tensioning cone 3 located at the one end la of the pulling pin 1. The other end lb of the pulling pin 1 is clamped by the clamping cartridge 4, which is fitted into the spherical hinge 6. In addition, the spherical hinge 6 is inserted through the through-hole 7b of the camping disc 7. In this way, the clamping disc 7, with the help of the spherical hinge 6 - the clamping cartridge 4 - the pulling pin 1, is secured to the supporting structure 8. The thermal insulation panel 9 s located between the supporting structure 8 and the clamping disc 7, which, in this way, is held up to the supporting structure 8 by the clamping disc 7.
In the case of the given embodiment the screws 11 are connected to the clamping disc 7, which secure the outside fitting 10 located on the external surface of the thermal insulation panel 9 to the clamping disc 7, and so indirectly to the supporting structure 8 as well.
The use of the securing unit according to the invention is as follows. The one end la of the pulling pin 1 must be pushed into the borehole 8a of the supporting structure 8 prepared with a borehole 8 a in such a way that the tensioning cone 3 gets to the end of the borehole 8a. Following this the helically wrapped tape 2a loosely applied to the tensioning cone 3 has to be pushed onto the tensioning cone 3. In this case in the part of the helical cavity 2b of the tensioning cone 3 where the helically wrapped tape 2a is located, the helically wrapped tape 2a slides inwards into the borehole 80, while the helically wrapped tape 2a opens outwards due to the increasingly larger cross-section of the surface of the tensioning cone 3. The wound windings of the pushed in helically wrapped tape 2a slide onto each other, and with this the helically wrapped tape 2a becomes tightened up in the borehole 8a of the supporting structure 8 between the supporting structure 8 and the tensioning cone 3, thereby securing the pulling pin 1 to the supporting structure 8.
Following this the thermal insulation panel 9 can be pushed onto and over the pulling pin 1 protruding from the supporting structure 8, the other end lb of which then protrudes out of the thermal insulation panel 9. The spherical hinge 6, including the clamping cartridge 4, and the clamping disc 7 encompassing the spherical hinge 6 can be pulled onto the protruding other end lb. Finally, using a dedicated tool, by pushing the clamping cartridge 4 in the direction of the supporting structure 8, and with the other end lb of the pulling pin 1 being tightened up, the grips 4c of the clamping cartridge 4, in the way illustrated in figures 5 or 7, tightens up and secures the other end lb of the pulling pin 1 and with this the thermal insulation panel 9 is forced up against the supporting structure 8. After this, the outside fitting 10 may be fitted to the clamping disc 7 on the outer side of the secured thermal insulation panel 9 using screws 11.
In this way the securing unit according to the invention may be positioned in an orientation which is intentionally not perpendicular to the plane of the supporting structure 8, and, with the help of securing units positioned at an angle, additional outside fittings 10 may be fitted to the supporting structure 8 via securing units supporting thermal insulation panels placed on the supporting structure 8. The reason for this is that the clamping disc 7 of the securing unit according to the invention is able to take on loads in a direction parallel to the plane of the thermal insulation panel 9, and transmit this load to the supporting structure 8 through the angled pulling pin 1.
