Description

ELEMENT AND METHOD FOR MANUFACTURING THE ELEMENT

The invention relates to an element comprising

- two disposed outer surfaces5 plates,

- an adhesive surface applied to one of the outer surface sheets,

- a frame structure for supporting the outer surface plates spaced apart, the frame structure being adapted to substantially conform to the circuit of the outer surface plate placed on the adhesive surface,

- at least one dielectric layer interposed between the outer surface panels, contained within the frame structure, wherein each dielectric layer comprises at least two parallel inserts arranged in a space limited by the frame structure, said dielectric being an air-impermeable material,

- a second adhesive surface disposed between the second outer surface plate and the insulating layer for securing the second outer surface plate to the insulating layer, and

a suction arrangement fitted within said frame structure to suck air from within the element.

The invention also relates to a method of manufacturing an element.

Prior art FI 105845 B discloses a method for producing an element and a corresponding element. The element includes outer panels and an insulating layer formed between the frame structure and the insulation therebetween. In the method, grooves are formed in the outer panel of the element through which vacuum is sucked in between the outer panels and the insulation by means of a vacuum to lock the components of the element together. For the final structure of the element, it is important that there is sufficient adhesive to lock the components of the element together. On the other hand, too much glue reduces the locking effect. For this reason, excess adhesive is sucked in by vacuum through the grooves away from the inside of the element through the suction port of the element. The problem with such a method and

20175854 prh 28 -11- 2018 element is that grooving is a laborious and time consuming step in element fabrication. In addition, the grooves and suction arrangements can clog the adhesive, preventing the removal of excess adhesive. Further, making a groove on the surface 5 of the dielectric layer reduces the contact area between the dielectric layer and the outer surface plate, weakening the bond between them.

Also known from the prior art is FI 94277, which has a metallic hollow solid profile which forms a frame structure and at the same time a suction arrangement inside the element. Through the profile, vacuum is drawn into the element. However, the problem with the structure of such an element is the weight of the hollow solid profile and the space occupied by it in the direction of the plane of the element. The solid profile contributes to a large cold bridge to the element.

US 6,138,435 A discloses a planar element having a profile serving as a stiffening structure on the sides. The element has a core and two overlays. The profile includes two parallel legs and a connecting structure between them. Ducts for suction of air between the topsheets and inside the core member are formed in the connection 20 structure.

It is an object of the invention to provide a more uniform element than the prior art elements. Features of the present invention will be apparent from the appended claim 1.

It is also an object of the invention to provide a more efficient and reliable method for producing elements than prior art methods. Characteristic features of this invention are apparent from the appended claim 11.

This object can be achieved by an element comprising two mutually disposed outer surface plates, an adhesive surface disposed on the surface of one outer surface plate, and a frame structure for supporting the outer surface plates spaced apart

20175854 prh 28 -11-2018, the field being substantially adapted to mimic the circuit of the outer surface plate placed on the adhesive surface. The frame structure is formed parallel to the plane of the outer surface plates by inwardly opening profiles of the element. In addition, the element comprises at least one dielectric layer disposed between the outer surface panels disposed within the frame structure, wherein each dielectric layer comprises at least two dielectric inserts arranged in a space limited by the frame structure, the dielectrics being air-impermeable material. Further, the element comprises a second adhesive surface disposed between the second outer surface plate and the insulating layer for securing the second outer surface plate to the insulating layer, and a suction arrangement fitted within the frame structure to suck air from the element. The suction arrangement includes at least one spacer component disposed between the insulators in each of the insulating layers to form an adhesive space.

By using the inwardly open profile of the element in the element according to the invention, the insulators can reach to the edge of almost 20 elements, leaving very little or no uninsulated area. In addition, the open profile is lighter in weight than the solid profile used in the prior art elements. When adhesive spaces extending across the insulators with substantially spaced frame dimensions are formed between insulators, the additional adhesive has a short distance to migrate to the adhesive space by suction, where it dries stiffening the structure and secures the insulators to one another. In this way, the adhesive can be used more generously, ensuring an adequate amount of adhesive, but at the same time ensuring that no excess adhesive is left between the outer surface plate and the dielectric to impair drying of the adhesive.

Preferably, in the element, the outer surface plates, open profiles, insulators and spacer components are locked into the element only

20175854 prh 28 -11- 2018 with adhesive and another adhesive. This eliminates the need for any intermediate steps in drilling, welding, screwing and other fastening.

Preferably, the spacer component is a supported spacer. The width of the insert allows the spacer to be formed, whereby the insulators are spaced apart and an adhesive space is formed. The bracket is also easy to make by bending it into a single piece.

Preferably, the spacer is carried substantially longitudinally in the middle of the spacer component. Hereby, an adhesive space is formed above and below the rim, allowing for the transfer of excess adhesive between the two outer surface plates and the insulator 15 to the adhesive space.

Preferably, the spacer is a thin sheet having a 3-12 ° span.

This creates a sufficiently large adhesive space on both sides of the edge. Making the spacers from a thin sheet is easy and the spacer itself is quite light and rigid.

Each insulation layer preferably has a plurality of insulators in parallel, and there is a spacer component between each of the two parallel insulators. Thus, a plurality of adhesive spaces between the insulators are formed in each insulating layer, whereby the adhesive has a sufficiently short distance to migrate to the adhesive space between the outer surface panel and the insulator.

The height of the spacer component between the outer surface panels may be 3 to 10 mm, preferably 4 to 6 mm less than the height of the dielectric. This allows the dielectric to collapse under a slight suction under vacuum.

20175854 prh 28 -11- 2018

The open profiles of the frame structure may be locked to the frame structure by gluing the outer surface plates. Thus, the open profiles do not need to be welded or otherwise fastened directly to each other to form a frame structure.

According to one embodiment, the insulator is a cell plate. In the cell plate, air pockets remain inside the structure, which act as effective thermal insulators.

In this context, it should be understood that although the suction arrangement is within the frame structure, the suction assembly included in the suction arrangement preferably passes through the frame structure to extract air from the inside of the element.

The adhesive used for the bonding may be, for example, polyurethane adhesive or other suitable adhesive for use. Preferably, the adhesive is a 2-component polyurethane adhesive that dries at 18 to 20 ° C for 40 to 60 minutes. The vacuum is maintained until sufficient structural strength is obtained for the adhesive bond 20 to maintain the bond even when returning to constant pressure. The amount of hardener is adjusted to the temperature to achieve the desired drying time.

The element may have 4 to 10, preferably 6 to 8, suction connections for connecting the adhesive space outside the frame structure to the suction means. Thus, it is important that the spacer pieces allow air to pass through the adhesive space longitudinally through the adhesive space between the insulators to provide a vacuum effect over the entire length of the adhesive space.

According to one embodiment, the spacer component is a sheet metal having a thickness of 0.5 to 5.0 mm, preferably 0.7 to 2.0 mm. In this case, the supported sheet has a sufficiently high stiffness to keep the insulators at a distance from each other in each insulation layer.

Preferably the profiles are U-profiles. There are many manufacturers of U-profiles and their availability is good.

According to one embodiment, one-

direction loose can also be installed between the insulators stiffeners, for example, a pipe. This is how the element can be added and stiffness. For example, if a pipe is used as a stiffener,

electrical cables can also be routed inside the pipe.

20175854 prh 28 -11- 2018

The object of the method according to the invention can be achieved by a method of manufacturing an element which comprises forming two outer surface plates arranged to be placed against each other, namely a first outer surface plate and a second outer surface plate and applying a first adhesive surface to the first outer surface plate. The frame structure parallel to the plane of the outer surface plates is formed using the inwardly open profiles of the element on the first adhesive surface to support the outer surface plates at a distance spaced substantially apart from the circuit of the outer surface plates. Inside the frame structure, a suction arrangement is formed to draw air from inside the element and an insulating layer within the frame structure by placing at least two insulators side-by-side on the first adhesive surface of the frame structure with the air impermeable material. Inserting at least one spacer between the insulators as part of a suction arrangement for forming an adhesive space between the insulators for additional adhesive, applying a second adhesive surface between the second outer surface sheet and the insulating layer and suctioning a a second adhesive surface for absorbing excess adhesive into the adhesive space.

In the method according to the invention, an element without welding or fastening steps can be made, since it is possible to produce a frame profile made of an open profile partially locks the insulators and the frame structure is glued together with the insulators by means of outer surface plates and glue. Thus, the exterior panels to be glued to the frame structure lock the open profiles of the frame structure to each other. By means of spacer components fitted between the insulators, at least one adhesive space can easily and quickly be formed inside the element, which can be transferred by the reduced pressure under the influence of the vacuum. Fasteners are also not required to form the adhesive space. In addition, the element can be assembled from discrete parts, whereby assembling of large elements and heavy welded pieces can be carried out without displacement, which is related to prior art methods.

Preferably, the method uses spacers spaced substantially longitudinally from the center of the spacer component to form an adhesive space 10 mm, preferably 15 mm wide, between the insulators.

Fabrication of supported spacers from a single piece by bending is remarkably fast. In addition, the spacers are

20175854 prh 28 -11- 2018 The element is easy to install without the need for a mounting step and is reliable to install.

Preferably, the frame structure is structured only

In the method, during operation, the open profile profile between the insulators can be formed by gluing the adhesive space by means of gluing of the peripheral surface panels.

placing a plurality of insulators in a single insulating layer and a plurality of spacer components between the insulators to form a plurality of adhesive spaces. In this case, the distance of the adhesive to the adhesive space between the insulation and the outer surface board is left

20175854 prh 28 -11-2018 short enough that the suction duration does not need to be prolonged excessively.

In the method, an adhesive may be used between 300 and 800 g / m ² , preferably 500 to 600 g / m ^2, between the insulating layer and each outer surface sheet. The method according to the invention makes it possible to use and utilize larger amounts of adhesive, since the excess adhesive is sucked into the adhesive space where, when cured, it contributes to the element's stiffening structure.

Preferably, the insulating layers are superimposed on one another in a direction perpendicular to the plane of the outer surface panels. The spacer components thereby contribute to the stiffening of the element structure in two directions. In addition, this prevents the use of standard-size insulators in the same insulation overlaps in different layers of insulation, which could impair their function.

Preferably, the adhesive surface is applied after the first dielectric layer with subsequent dielectric layers to the previous dielectric layer. In this way, the insulation layers are also glued to each other.

In the process, a momentary vacuum of 0.5 to 0.95 bar, preferably 0.6 to 0.8 bar can be used to suck the adhesive into the adhesive space. A sufficiently high vacuum is thereby obtained to absorb the adhesive between the outer surface plate and the insulation in the adhesive space of the suction arrangement. At the same time, the vacuum is sufficient to pull the outer surface plates firmly against the insulation and the frame structure, whereby the outer surface plate is glued in place to provide a friction lock. The outer face plate should be selected so as to be sufficiently flexible to bend under vacuum to the film to provide film contact.

Preferably, the method employs a non-grooved and flat surface insulator to increase the contact surface between the insulator and the outer surface panels. This avoids the additional step of grooving and provides an increased contact surface between the insulation and the outer surface panel.

The increased contact surface allows for a stronger adhesive bond between the outer surface panel and the insulation.

Preferably, the method comprises forming a frame structure on one side open for installing insulators and closing the frame structure to a closed circuit by means of one of said profiles after installing the insulators. This facilitates the installation of insulators inside the frame structure.

Preferably, the outer surface panels, open profiles, insulators and spacer components are attached to the element using only the adhesive surface and the second adhesive surface. This avoids work and material costs associated with welding, drilling and screwing.

The invention will now be described in detail with reference to the accompanying drawings, in which:

20175854 prh 28 -11- 2018

Figures 1-6 illustrate the steps of the method of the invention by illustrating an embodiment. It will be appreciated that the description only shows one possible method and embodiment of the element and, for example, the number of insulation layers and the dimensions of the element 25 may vary between different embodiments of the element.

As shown in Figure 1, the first step is to form the outer surface plates 12. In this case, the individual first outer surface plate 12.1 shown in Figure 1 consists of a single 2500 mm wide sheet metal strip 12 '. In this case, the width of the sheet metal strip is determined by the width of the sheet metal sheet.

Alternatively, two sheet metal strips with a width of 1250 mm can be joined by gluing them over a width of approximately 50 mm, whereby the overall width of the outer surface sheet is 2400 mm.

In addition to gluing, there may be taping along the overlapping portion of the sheet metal strips to seal the joint of the sheet metal strips so that it is airtight. At the same time, a tight connection prevents the adhesive from coming out of the element.

Preferably, the material of the outer surface panel is galvanized sheet metal, but composite, wood or the like may also be used in the structure. The thickness of the damper may be 0.5 to 5.0 mm, preferably 2.0 to 3.0 mm. Although only one outer surface plate is shown in Figure 1, it should be understood that at the same time, two outer surface plates are preferably fabricated, one of which serves as the inner surface of the element when installed and the other outer surface for its intended use.

Preferably, the first outer surface plate is placed on a table for assembly, on which may be formed a mold structure, or jig, to facilitate assembly. The mold structure may also have edges which facilitate the formation of the frame structure 20. This mold structure is not shown in the drawings as it is not part of the invention. The mold structure may be similar to the state of the art when assembling elements.

20175854 prh 28 -11- 2018

As a second step, an adhesive surface 16 is applied to the first outer surface plate 12.1 of Figure 1 and a frame structure 20 is formed thereon as shown in Figure 2. According to the invention, the frame structure 20 is formed of open profiles 24 which open towards the center of the element. In other words, the open profiles 24 are on the side. Preferably, the profiles 24 are so-called U-profiles as shown in Figure 2. Preferably, the mold structure is used to assemble the frame structure against which the open profiles are placed. Preferably, the open profiles are only aligned with one another, but there is no direct attachment between the open profiles. This avoids work on attaching the profiles. For example, the frame structure may be 200 mm deep relative to the normal plane of the outer surface plate 12 and made of an open profile having a wall thickness of 10 mm. The profile is preferably made of steel, but may also be, for example, composite.

Frame structure 20 is a circuit constituting circuit of outer surface plate 12 forming four circuits.

from side j

Preferably, the composite, pre-assembled circuit of the picture is left to remain open on one side in a substantially frame structure during assembly, and is closed only after insulating.

The frame structure 20 adheres to the outer surface panel 12 by means of an adhesive surface. The profiles of the frame structure 20 are preferably fitted with the suction connections 44 of the suction arrangements 18 shown in Figures 2, 3a, 3b, 5, through which air entrained in the element 10 can be sucked out.

20175854 prh 28 -11- 2018

In the third step shown in Figure 3a, at least two insulators 22 are placed on the inside of the frame structure 20 against the adhesive surface 16. In Figure 3a, there are three pieces of insulation 22.

The individual dielectric 22 may be an assembly of one or more pieces that fills the space between the spacer components. For example, the width of the insulation may be 60 cm. The dielectric is an air-impermeable material such as polystyrene, urethane or similar hard material. The insulation may also be hard wool, but its pressure resistance is significantly lower than the aforementioned hard materials. According to one embodiment, the dielectric may be a honeycomb structure having particularly good insulating capacity.

Preferably, the insulators 22 rotate the inner surface of the profile 24 of the frame structure 20 along the entire circumference of the frame structure 20 as shown in Figure 6. The insulator 22 is positioned against at least one spacer 34 serving as a spacer component 26. Preferably, dielectric 22 is

20175854 prh 28 -11- 2018 non-grooved and smooth surface. In this context, the term "uniform" means that it is uniform in accordance with the standard requirements for the manufacture of ordinary insulators.

3a to 3c, the suction assembly 18 comprises spacer components 26 which serve to provide an adhesive space 28 between the insulators 22 to be installed within the frame structure 20 in steps 3a, 3b and 4, in addition to forming an adhesive space 28. a structure between the insulators 22 to improve the stiffness of the element. In practice, the adhesive space 28 is an empty space between the insulators 22. Preferably, the suction connections 44 are included as part of the suction arrangement 18 to provide a passage for air through the frame structure 20.

The spacer components 26 may be, for example, spacers 34 according to Figures 3c, 6 and 7 mounted between each of two adjacent insulators 22. The spacers 34 may be, for example, elongated supported structures 20 made of sheet metal. Thus, the tab 38 may be located substantially in the middle of the spacer 34 and extend longitudinally of the spacer as shown in Figure 7. The width of the spacer at the distance between the insulators 22 may be, for example, 10 to 30 mm, preferably 15 to 20 mm. The spacers 34 may have a thickness of 0.5 mm to 3.0 mm, preferably 25 mm to 2.0 mm. The spacers are preferably uniform throughout the adhesive space, but there may also be several spacers in succession. The material used in the spacers may also be plasticised corrugated board or composite instead of a metal sheet. According to one embodiment, the depth of the spacer components 26 30 between the outer face plates may be nearly the same as the depth of the insulating layer, i.e., when the insulating layer is 200 mm deep, the spacer components may have a depth of, for example, 195 mm. In this case, the spacer component does not prevent the outer surface plates from bending

20175854 prh 28 -11-2018 Effectively low pressure effectively on film contact with insulators as the insulators collapse slightly.

It is essential for the spacer component of the element according to the invention that the spacer component allows the passage of air along the entire length of the adhesive space parallel to the spacer component. The vacuum effect provided by the suction thus extends over the entire space of the adhesive space and the adhesive is absorbed along the entire length of the adhesive space between the insulation and the outer surface panel. Therefore, the spacers are preferably supported or bent longitudinally so as to allow air passage longitudinally of the adhesive space from the suction connections around the adhesive space.

In Figures 2, 3a and 4, one of the profiles 24 of the frame structure 20 is dropped off during the installation of the insulators 22 and is not installed until after the insulators 22 have been installed, enclosing the frame structure 20 into a closed circuit. Alternatively, the frame structure may be closed with respect to its circuit, in which case the insulators 22 must be bent in order to be fitted inside the profile 24 as shown in Figure 6.

As shown in Figure 4, in addition to the insulator 22, a further stiffening structure 30 may be added to the element 10 to further stiffen the overall structure of the element.

For example, as shown in Fig. 4, the stiffening structure 30 may consist of a slightly smaller surface area of plywood 31 which is mounted and glued between the insulating layers 14.

4, in addition to the first dielectric layer 14 of Figs. 3a and 3b, preferably 1-2 dielectric layers 14 stacked in the normal direction of the plane of the outer surface panel 12 within the frame structure 20 are provided. Preferably, the insulating layer is glued to one another by means of an adhesive surface applied to the surface of each insulating layer 14.

5, in the fourth step, the structure of the adhesive surface is glued to the surface of the frame filled with insulators.

The 16 'covers the entire outer surface of the second outer surface panel, even if only with a small one

20175854 prh 28 -11- 2018

After the installation of the second outer surface plate, the suction arrangements 18 are used to suck up the air inside the element 10, whereby the external surface plates 12 are sucked tightly against the frame structure 20 and the insulation 22 More specifically, suction means 44 of suction assembly 18 can be combined with suction means, such as a compressor, which preferably produces a vacuum of 0.8-0.9 bar, i.e. about 0.2 bar abso20. The adhesive space 28 formed by the spacer components 26 is sucked into the suction arrangement 18 by means of vacuum to squeeze the adhesive between the outer surface plate 12 and the dielectric 22 while uniformly spreading into film contact. The excess air ends up in the adhesive spaces between the insulators 25. Because there are preferably only 1 to 3 suction connections 44 on each side of the open profile formed by the frame structure, air is drawn from the adhesive space between the dielectric and the open profile due to surface irregularities of these components. Alternatively, the suction ports may be directly aligned with the adhesive spaces.

In the adhesive space, the spacer components cover only a small portion of the cross-sectional area of the adhesive space, leaving 95 to 99% of the area free. The free area is shown in Figure 6 under reference number 46.

20175854 prh 28 -11- 2018

The free surface area allows air and partly the movement of the adhesive in the adhesive space. Preferably, the suction ports are spaced apart from the outer surface plates between the outer surface plates, whereby excess glue does not end up in, or through, the suction ports of the suction arrangements where it rapidly clogs the air channels.

The external dimensions of the element according to the invention may be, for example, 6mx3mx0.2m, where 6m is the width of the element, 3m in height and 10m in depth. The dimensions of the element can vary considerably from this, as the method of the invention can be utilized in several different dimensions. The element according to the invention can be used without separate stiffeners as a non-load-bearing element with which the walls of the building have a separate load-bearing frame.

A preferred application for the element according to the invention is various light element buildings, such as electric transformer copiers and the like, in which the elements are not subject to high load-bearing requirements. Other applications include RTG modes 20 and other airtight electrical and automation modes. The stiffened elements may also be used as roofs and floors. When used as a roof, the element can be covered with sheet metal and the floor can be covered with plywood. Lightweight prefabricated buildings can also be assembled without welding using corners that are glued in place between the elements.

Preferably, the corner moldings use integrated presses which press the elements against each other while gluing the assembly into a finished lightweight element building.
