The object of the invention

The subject invention is a mounting device, in particular for fastening of sandwich panels to beams constructive or appropriate fragments.

The subject invention is also of a sandwich panel containing at least one insulating layer of heat-insulating material.

In addition, the subject invention is a section of the wall containing at least one sandwich panel according to the invention, mounted on the beams or corresponding structural fragments.

The level of technology

To prevent, especially on the external walls, the deflection of multilayer elements relative to the beams or other structural fragments due to changes in temperature and suction of wind, the sandwich panels are usually fastened to the beams or structural fragments by means of mounting screws penetrating the multilayer element. This method, however, does not account for the curvature or floor deformation caused by, for example, varying load on the floor. This can lead to deformation in sandwich panels (e.g., panels of mineral wool having a core made of mineral wool, which is situated between two elements of a covering of sheet metal) and her plating. In addition, the mounting screws penetrating the multilayer element, bring with�Oh the risk of leakage of heat and at the same time to violate the aesthetic experience as a whole.

Disclosure of the invention

In order to avoid the above described problems inherent in the prior art, the mounting device according to the invention is characterized in that it comprises at least one plate having at least one groove, wherein the plate is configured to attach in a fixed manner to the surface of the sandwich panel, and comprises at least one essentially L-shaped profile element having at least one locking mechanism that is included in the groove of the plate, wherein the profile element is made with the ability to attach in a fixed manner to beams or appropriate constructive fragment, which when the locking profile of the element introduced into the grooves of the plate, the plate and the specified profile element have reciprocal mobility relative to each other in the longitudinal direction of the grooves, with their relative displacement in the direction perpendicular to the main surface of the plate, limited or substantially completely blocked.

The grooves on the plate can be open or closed.

The expression "closed groove" or "locked grooves" in the present invention, it should be understood, the grooves providing a possibility of removal of fixation devices are placed in them, only in its longitudinal direction. The term "outdoor PA�" or "open slots" in the present invention should be understood grooves, providing the ability to extract fixation devices are placed in them, not only in its longitudinal direction, but also in at least one direction in a plane perpendicular to the longitudinal direction of the grooves, for example, so that the plate having open grooves, and the profile element are parallel to each other and perpendicular to the longitudinal direction of the grooves can be in one direction are at to each other and fixed together, and in the opposite direction are disconnected from each other when the plate and the profile element is not attached to any other objects, for example beams or sandwich panels.

Locked grooves preferably are, for example, T-shaped slots or grooves in the dovetail. In a preferred embodiment the open slots, as well as clips, are in its longitudinal direction essentially L-shaped cross-section.

In a preferred embodiment the mounting device according to the invention the plate with its rear side is provided with glue or double-sided tape, protected by a removable protective material (for example, with protective paper).

In a preferred embodiment the mounting device according to the invention, the profile element is essentially L-shaped. Core elements�t may also be essentially J-shaped, provided his retainers form a L-shaped cross-section.

Multilayer element according to the invention is characterized in that in the upper part of one surface of the specified sandwich panel is attached to at least one plate having at least one groove, and the said plate is intended for fastening of sandwich panels by means of the profile element having at least one locking mechanism that is included in the groove of the plate, wherein the profile element is made with the ability to attach in a fixed manner to beams or to the corresponding constructive fragment by means of appropriate screws or fastenings, and the said plate and the specified profile element essentially fix the panel in position, perpendicular to the surface of the sandwich panel due to the fact that their relative movement perpendicular to the major surface of the plate is limited or essentially completely blocked, but can be offset sandwich panel relative to the beam or of the corresponding structural fragment in the longitudinal direction of the grooves.

In the multilayer element according to the invention the grooves of the plates are open or closed. Closed slots of the plate are preferably T-shaped slots or grooves in the shape of a bird x�OST. In a preferred embodiment the open slots, as well as clips have in their longitudinal direction essentially L-shaped cross-section.

In a preferred embodiment, the sandwich panel according to the invention the plate is attached to the surface of the sandwich panel by means of adhesive or double-sided tape. The plate may optionally be fixedly attached to the surface of the sandwich panel by means of rivets or other suitable fastenings, which can penetrate into the sheathing or surface layer of the panel. The grooves of the plate, for example, are T-shaped slots or grooves in the dovetail.

In a preferred embodiment of the multilayer element according to the invention, the profile element is essentially L-shaped. The profile element can also be essentially J-shaped, provided that the clamps form a L-shaped cross-section.

In a preferred embodiment of the multilayer element according to the invention a multilayer element contains only one insulating layer of heat-insulating material. This insulating layer contains mineral wool and placed between two elements of a covering of sheet metal and is fixedly attached thereto. Instead of mineral wool as heat insulation material in izoliruyushchie (layers) may also be used any other insulating material having a lambda value (λ-value), for example, less than 0.1 W/(m·K).

Section of the wall according to the invention contains at least one sandwich panel according to any one of claims.7-14, wherein the sandwich panel is fixed on the beams or the corresponding structural fragment, such that each plate through the grooves attached to the profile element having at least one locking mechanism included in the slots of the plate, wherein the profile element is attached to the beams or to the corresponding constructive fragment, whereby the said plate and the specified profile element essentially fix the sandwich panel to a position perpendicular to the surface of the sandwich panel due to the fact that their relative motion perpendicular to the major surface of the plate is limited or essentially completely blocked, but allow displacement of the panels relative to the beams or of the corresponding structural fragment in the longitudinal direction of the grooves.

In a preferred embodiment of the wall according to the invention the grooves are in its longitudinal direction essentially vertically and thereby provide the possibility of vertical displacement of the floor structure relative to the section of the wall.

According to the invention the number of plates having �basics, one multilayer element is at least one. If you use only one plate, it can be like a ribbon on top of one of the surface layer (for example, sheet metal surface) over the entire width or length of the sandwich panel. The plate can also be significantly shorter. When using multiple plates, they can be located at equal distances from each other along a line that passes across the surface of the sandwich panel. The plate may also be located in groups, for example, three plates, so that the distance between the plates in one group is equal to the distance between each group, but greater than the distance between the plates in one group. The grooves in the plates are preferably longer than the clips essentially L-shaped profile elements, so that they, in the case of vertical displacement, for example, gender, vivenciada from the grooves of the plates.

As already mentioned above, according to the invention it is preferable that the open grooves, and the latches had in its longitudinal direction essentially L-shaped cross-section. The advantage of this variant implementation is that is achieved by fastening sandwich panels, in which there is tolerance in the outward direction of about 5 mm. Plate and profiled element thereby fix the sandwich PA�spruce on the merits in position vertically relative to the surface of the sandwich panel due to the fact, their relative motion perpendicular to the major surface of the plate is limited in such a way that the fixing points provided the movement of the sandwich panels is approximately 5 mm to the outside of the supporting structure. During construction (walls or roof) this means in practice that the load caused by deformation of the panels due to temperature differences between the outer and inner sides of the panels are reduced. The measure of this decrease depends on the length (the length of the panel) and the thickness of the panel. It can be approximately 1 kN/m at the edge of the beams, i.e. 100 kg load per metre. For an item this means that it either remains without any deflection (fracture), or sags. It should be noted that the normal wind load is only 0.6 kN/m2if a building has a height of about 10 m in Finland and Sweden, therefore, this circumstance is very important.

In addition, the above-described variant implementation provides the ability to manufacture only one instrument for the plate, and preferably essentially L-shaped profile element (which curves through the element corresponding to the plate) and not two as for the T-shape grooves or slots in the dovetail.

The invention makes it possible to realize the fixing of sandwich panels�her for example, sandwich panels with a core of mineral wool between two items of paneling, sheet metal, and fastening is flexible in the vertical direction, but essentially captures the sandwich panel in the direction perpendicular to the surface of the sandwich panel due to the fact that the relative movement of the said plate and the specified profile element perpendicular to the major surface of the plate is limited or essentially completely blocked (which prevents the buckling of sandwich panels relative to the beams or of the corresponding structural fragment). Pinning can be used to attach single-span panels and multi panels of the intermediate supporting elements (columns and beams) without mounting screws penetrating the sandwich panel.

The term "sandwich-panel" should the present invention be understood, along with others, multi-layer roof, wall and façade panels and multi-layer ceilings and internal wall panels containing at least one layer of the insulating material. A sandwich panel containing a core of mineral wool placed inside and attached to the two surface layers or elements of a covering of thin sheet metal, may also be mentioned in the qu�ve examples of such sandwich panels. The components of the sandwich panels are preferably connected to each other so that they form supporting composite panel (composite element). Sandwich panel according to the present invention must also meet certain minimum values of tensile strength and compression strength, are necessary to avoid separating the various layers, whereas the trends of the sandwich panel to bending counteracts the mounting device according to the invention.

Fig.7 illustrates a sectional view from above, as a section of the wall of Fig.6) are fixed in the column.

Fig.7 discloses an embodiment of a flexible mounting device according to the invention is intended, for example, for lightweight sandwich panels Paroc, wherein the mounting device uses high tensile strength and the compressive strength of these panels (see table 1 below for examples of minimum values). The fastening device comprises a plate 3 having five identical parallel T-shaped grooves 7, and essentially L-shaped profile element 4 is provided with five identical locking devices 8 having in cross section T-shaped, so that they can be inserted into the grooves 7 in order essentially to prevent any relative movement of the plate 3 and the profile element 4, except for the relative displacement of the plate relative to the profile element in the longitudinal direction of the grooves 7. In the example of Fig.1 grooves formed at an equal distance from each other, but they can also be performed n� different distances from each other. Fig.1 essentially L-shaped profile element 4 is provided with a locking device 8 on the outer surface on both the shorter and the longer the bar L-shaped element, but, in principle, it is sufficient when there is a locking mechanism on the outer surface of only one of the arms, and, preferably, to a shorter horizontal bar.

Fig.1, the groove 7 of the plate 3 has a T-shaped profile cross section, but the grooves 7 can be, for example, in an alternative embodiment, the so-called grooves in the dovetail, resulting in the fixture profile element is designed in such a way as to have a response section in order essentially to prevent any relative move�shift of the plate 3 and the profile element 4, in addition to the relative displacement of the plate relative to the profile element in the longitudinal direction of the grooves 7. Fig.1 the number of grooves 7 in the plate 3 and the fasteners 8 in the profile element is five, but the number may, depending on the size of the plate also be different, for example 1-10 grooves on one plate. Plate 3 and the profile element 4 is preferably made in an independent manner, as one piece by molding of a suitable metal such as steel or aluminum, to obtain the necessary forms.

The mounting device of Fig.1 can be used, for example, for fastening of sandwich panels to the intermediate beams, the risk of deformation due to load. Plate 3 and the profile element, the mounting device 4 is then mounted so that the grooves 7 of the plate in its longitudinal direction was vertical. The result is a consolidation of the sandwich panel, wherein the pin is vertically flexible/movable, but fixed in the horizontal direction (prevents buckling of sandwich panels relative to the beams or other structural fragments). The plate 3 with the grooves 7 of the mounting device is attached to the surface of the panel, the tabs 8 of the profile element 4 is inserted into the grooves of the plate and attach to Balk�m or other constructive fragments, for example, the column or the beam. The mounting device may also be used to secure multi-span panels to the intermediate supporting elements (columns and bars) without penetrating the mounting screws. To the mounting device to withstand a force (F) stretching up to 5000 N, the plate 3 and is essentially L-shaped profile element 4 made of aluminum or steel should have a certain minimum wall thickness. This minimum wall thickness depends in part on the number of grooves, and in the example of Fig.1, in which five of grooves distributed on the plate with uniform spacing between them at the length of 300 mm and a width of 200 mm, the minimum wall thickness is 2.5 mm.

Fig.2 illustrates how the sandwich panel 1 (attached to the upper and lower sandwich panels by sheet piling compounds) containing, for example, a core of mineral wool 13 button located between the two sheets 2, 7 metal (for example, sheets of aluminum or steel), fixed on the horizontal beam 5 by means of four identical plates 3, 3', 3", 3"', each of which has four groove and attached to the surface of the "inner" of the metal sheet 2, which is located on sandwich panel 1, and four essentially identical L-shaped profile elements 4, 4', 4", 4"', with four clamps and four su�the Swedish L-shaped profile member is secured to the upper surface 6 of the beam 5 by means of screws (and the corresponding holes for screws, available in essentially L-shaped profile element). In this example, the grooves due to their shape are called grooves in the dovetail, and clips provided essentially L-shaped profile elements 4, 4', 4", 4"', have the same shape in cross section. Plate 3, 3', 3", 3"' attached to the sandwich panel 1 by means of glue or double-sided tape with a smooth back side of the plates (glue/double sided tape not shown). In addition, plate 3, 3', 3", 3"' between the grooves can optionally be provided with holes for fastenings, such as rivets or screws, which can additionally strengthen the connection of the plates with the panel. These fastenings are not required, however, to penetrate into the panel through but only directly to the depth from the inner side (the side that is closest to mineral wool) inner metal sheet 2. These fixtures are not necessary because of glue or double-sided tape enough to withstand a horizontal tensile force of 5000 N.

Fig.3 discloses another embodiment of a mounting device according to the invention, in which the plate 33 has open grooves 77, the cross section of which in the longitudinal direction of the grooves is essentially L-shaped, having a shorter and more long�th crossbar. Longer "crossbar" L-shaped element is held out perpendicular to the major surface of the plate 33, and a shorter "crossbar" L passes to the outside of the longer crossbar parallel to the main surface of the plate 33. The retainer 8 is essentially L-shaped profile element 44 has a shape except for a bent section 11 of the profile element 44, identical to the grooves 77 of the plate 33. Since the grooves 77 are open (have the form of essentially L-shaped profile element), as the plate 33 and the profile element 44 (to give it an L-shape 44) can be manufactured by the same devices. Plate 33, and a profile element 44 have openings 10 and 9 for screws, providing the possibility of fixing with wood screws or appropriate mounting hardware (not shown) to sandwich panels and the supporting structure, respectively. On the curved area 11 of the retainer 11 of the profile element 44 there is no shorter "crossbar" of the profile element.

Fig.4 it can be seen that the grooves 77 of the plate 33 and the latches 88 of the profile element 44 is fixed between them. Plate 33 and the profile element 44 through the openings 10 and 9 are screwed by means of screws for sandwich panels and the supporting structure respectively so that rela�ejstvujuschij groove 77 and the corresponding fixture 88 includes each other thus, that shorter crossbar L-shaped profile of the respective retainer positioned perpendicular to the longer of the crossbar L-shaped profile corresponding groove 77 and Vice versa. Since the space between the shorter crossbar L-shaped profile of the respective retainer 88 and the main surface of the profile element 44 is greater than the thickness of the shorter crossbar L-shaped profile corresponding groove 77, there is a free space (for example, 5 mm) for the relative motion of the plate 33 and the profile element 44 toward and in opposite directions in a plane perpendicular to the main surface of the plate 33 and the main surface of the shorter end of the profile element attached to the plate 33.

As the plate 33 is attached to the fixed panel, and a core element 44 is attached to a fixed supporting structure, the mounting device according to Fig.3 and 4 may not reseedings, even if the grooves 77 and the locking tabs 88 are open in one direction. In this regard, the mounting device of Fig.3 and 4 provides the possibility that, when the locking profile of the element introduced into the grooves of the plate, the plate 33 and L-shaped profile element 44 have only the possibility of displacement relative to each other in the longitudinal direction of the groove�in, however, their relative movement perpendicular to the major surface of the plate is limited by the space between the shorter crossbar L-shaped profile corresponding fixture 88 and the main surface of the profile element 44 (plot, parallel plate 33).

Fig.5 discloses a schematic side view of a variant of implementation according to Fig.3 and 4. In this figure, it is shown that the L-shaped profile element 44 on the curved area 11 has a rounded edge between the short and long rails L-shaped element 44.

Fig.6 is illustrated in a side view, both vertically located so-called multi-span panel 1 (in this case, wall panel) is fixed to the column 55 (here with a square cross-section) through the mounting device according to the invention, in this case, the plate 33 and L-shaped profile element 44 providing fastening without the use of mounting screws penetrating the sandwich panel 1. Each plate 33 is attached to the sandwich panel 1 with its inner side part in the form of double-sided tape (not shown) from the back side of the plate and partially by means of rivets (not shown). Each respective L-shaped profile element 44 is attached in the same manner as the plate 33, by means of double-sided tape (�e shown) and screws 12 to the column 55. Plate 33 adjacent to the panel 1 so that the plate and a shorter crossbar L-shaped profile element 44 is placed between the panel 1 and the column 55, with a longer crossbar L-shaped profile element 44 are arranged on two opposite vertical walls of the column 55, and the plane surfaces of these walls are essentially vertical and essentially simultaneously perpendicular to the plane surface of the large panel surfaces. Fig.6, which illustrates only a portion of the sandwich panel 1, shows two pairs of plates 33 together with L-shaped profile element 44. The number of plates 33 with the respective profile elements 44 that needs to be fixed on one sandwich panel 1, depends on the size of the sandwich panel.

Fig.7 illustrates in cross-section in plan view of the sandwich panel 1 in the embodiment of Fig.6 is attached by means of a mounting device according to the invention to the column 55 from both its opposite vertical walls essentially at the same height.

Single-span or multi-span panel may be mounted by the mounting device according to the invention on a vertical (e.g., the column) and horizontal load-bearing structure (e.g. a beam) simultaneously�NGOs.
