SI24327A - Anchors for affixing vip or vise thermal insulation in the facade systems and other systems and the affixing procedure - Google Patents

Abstract

The invention presents a system for fixing insulating panels from VIP or VISE panels, the special feature of which is that they must not be pierced with anchors or cut to other formats, or in any way mechanically damaged. This is achieved using special anchors. The structure, shape and position of the anchor are such that they cause the additional heat bridges to the minimum possible, so that they are minimally affected by the extremely thermal insulation of VIP panels and VISE composite panels.

Description

The invention relates to anchors for fastening thermal insulation panels in façade and other systems and the process of fixing and falls within the field of construction.

Description of a technical problem

Vacuum Insulation Panels (VIP), as well as Vacuum Insulation Sandwich Elements (VISE) are the most efficient thermal insulation known to date, due to the extremely low thermal conductivity. They are used where there is not much space available and are at the same time an exception to the strict requirement of thermal insulation.

Current state of the art

Most of the exterior cladding of buildings have a significant increase in thickness due to new energy-saving requirements; so the thickness of thirty or more inches in the facade, roof or floor of a building is not uncommon. Highly economical buildings require thermal transmittance (denoted by U) even below 0.10 W / (m K), which, using conventional thermal insulation materials, results in a minimum of 30 cm and often as much as 50 cm of additional thickness in circumferential structural assemblies. Not only are technical limitations, which are reflected mainly in the problems of fixation, but also negative aesthetic reasons.

We must be aware that such extreme thicknesses of thermal insulation layers are always at the expense of the utilization of the floor plan of the building, since in cases where the external dimensions of the building are limited, the net discharge of usable surfaces of buildings is much smaller, and thus the financial result of the investment project is worse. On the other hand, it is also true that architects and other designers want to design and save space, not build structural assemblies that, in both dimensional and free space, contain a predominantly thermal insulation part. Thus, conventional thermal insulation materials prove to be very wasteful with space.

Vacuum insulation panels VIP and VISE composite panels, thermal insulation panels, are significantly more efficient, even up to ten times more than the previously known and expanded thermal insulation materials. Thermal conductivity can only be 0.003 W / (mK) or 3

A mW / (m'K) and thermal resistance of only 20 mm thick panel even 6.66 (m K) / W. With the help of advanced and innovative technology, we achieve high thermal resistance at extremely low thickness. Not only layers of thermal insulation, but entire systems of thermal insulation facades, walls, parapets, floors, terraces and flat roofs can be up to five times (5x) thinner!

The problems that arise when using VIP panels and VISE composite panels, especially when used for thermal insulation in facade systems, are their high sensitivity. They must not be cut, cut or otherwise mechanically damaged. In advance, it is necessary to prepare the panels in certain dimensions according to the assembly plan, avoiding the choice of small formats VIP panels and VISE composite panels, as well as narrow elements. The larger the panels and panels, the better the initial thermal insulation and the better the resistance to aging. For dimension-sized VIP panels, the proportion of edges and welds of the foil is relatively smaller when compared to the surface of the panel, which makes the preservation of vacuum and thus the thermal insulation properties much better. Attaching or anchoring through individual VIP panels is not allowed, as in this case individual panels will be damaged, which will result in additional heat losses.

They should be laid on substrates that do not contain sharp particles. Also, sharp particles should not contain layers that follow panels and panels. Care must be taken when transporting, storing and manipulating VIP panels and VISE composite panels. We must also prevent mechanical damage during assembly and use. Practice shows that injuries occur mostly before and during the installation of panels.

The problem with using these panels is their attachment or anchoring to the facade. The known procedures include the use of various fasteners that "damage" the panels. Therefore, the known procedures for attaching different thermal insulations to the facades for VIP panels and VISE panels are not appropriate.

Previously known systems for attaching VIP panels and VISE composite panels include the use of tapes or. laths laid between contacts. We know the systems where VIP contacts are

panels or VISE composite panels inlay strips or. laths that have significantly less thermal insulation. Most often they are made of polyurethane foam, through which we can anchor with screws, with the help of which we can also attach the facade finishing, as in the case of other dry mounting linings. Because the lining is tightly fastened via straps or. there is no need for additional anchoring or fastening of the laths into the substrate, even of the VIP panels or VISE composite panels. The disadvantage of this solution is that it has much more pronounced thermal bridges, since the heat-insulating panels from which the strips or panels are made. laths, at least 3x more thermally conductive than VIP panels and MORE composite panels.

It was necessary to develop a new system for attaching VIP panels and VISE composite panels to the facade, in order to avoid damage to VIP panels and VISE composite panels as much as possible. This was achieved with a new anchor design and anchoring system.

Description of the new solution

In the case of the solution according to the invention, the technical problem of attaching thermal insulation from VIP panels or VISE composite panels is solved with a new anchor and fastening process, which has the following advantages:

the new anchor, H-shaped and double-H-shaped, allows the said insulation panels to be fastened without being pierced by the anchors or otherwise mechanically damaged during assembly or during service life;

The anchor is shaped so that it can be screwed into the wall, a groove of thermal insulation board, primarily a multi-layered VIP panel, or an insert is inserted into the anchor pin itself. MORE composite panels;

proceed by inserting a new anchor with a pin into the groove of the next insulation board and screwing the anchor into the wall, repeating the process and continuing in the same order; in addition to anchoring the VIP panels and the VISE composite panels, they are also simultaneously glued to the base of the outer wall, thereby achieving good contact of the VIP panels and the VISE composite panels with the base, so that a facade can be attached to the panels thus affixed and glued; the anchor pins extend into the grooves already made in the thermal insulation panel at the factory, in this way the panels touch each other without any additional materials affecting the formation of thermal bridges;

the anchor does not extend to the exterior surface of the façade from the VIP panels and the VISE composite panels, therefore it is deepened below the surface of the façade only, thus reducing the intensity of the point thermal bridge to a minimum.

The invention will be described by way of embodiments and illustrations showing:

Figure 1: Displays single pin anchor ("H" shape)

Figure 2: shows the installation of thermal insulation in a single layer with a single pin anchor Figure 3: schematic illustration of the position of the anchor and the method of fixing the thermal insulation in a single layer Figure 4: shows the double pin anchor ("double H" shape)

Figures 5a, 5b, 5c, 5d: show the installation of thermal insulation in two layers with double pin anchor

Figure 6: Schematic illustration of one of the possible attachment methods

The single-pin anchor is H-shaped (Figure 1) and is intended for the implementation of a single-layer thermal insulation cladding in the façade system, the double-anchor anchor is in the form of a double H (Figure 4) and is intended for the implementation of the two-layer thermal insulation coating. multi-layer VIP panels and VISE composite panels, secures the second layer of thermal insulation, which also has grooves and slots into the additional pin with the slots. Both layers of panels can also be glued together.

As a rule, the anchors fit into the panels on the lower and upper sides (Figure 6), so that they can also be anchored on the left and right sides or vice versa. It is, however, advisable that the anchors be placed at the edges of the longer sides - so that the panels are better quality by bridging the shorter panel distance.

In both versions, using a single H anchor (Fig. 1) for a single-layer thermal insulation lining system, as well as using a double H anchor (Fig. 4) for the facade system with a two-layer thermal insulation lining, the basic surface is followed by the reinforcement surface. mesh, and finishing façade rendering according to the Contact Insulation Facade System (English ETICS - Extemal Thermal Insulation Composite System or German WDVS W arme-Dahm-V erbund-S ystem).

♦ ·

The anchor is made of plastic material such as PE, HDPE, PS or the like, which should have as little thermal conductivity as possible. The process of anchor production can be by extrusion and cutting, as the anchor shape is constant, or the anchor is made individually.

Figure 1 shows a single pin 1 anchor consisting of a base plate 2 with screw holes 3, connecting plates 4 and pin 5, each individual anchor elements having a single pin 1 interconnected to form the letter H. The base plate 2 and the pin 5 are parallel to each other, with the upper anchor part of the upper pin line below the plane of the holes for the screws 3, the width of the anchor or. of the connecting plate 4 depends on the position of the groove in the thermal insulation or. indirectly from the thickness of the thermal insulation.

Figure 2 and Figure 3 illustrate the fastening procedure when a single pin 1 anchor is screwed into the wall with a bolt, and a groove 9 of the thermal insulation panel 10, primarily a multi-layer VIP panel, or an insert is inserted into the pin itself. MORE composite panels. Continue by inserting a new single pin 1 anchor with pin 5 into the groove 9 of the insulating panel 10 on the other side and screwing in a new single pin 1 anchor into the wall. We repeat the process and continue in the same order. When installed, the thermal insulation panel 10 with the part between the inner side of the panel, which is closely adjacent to the wall and groove 9, in the space between the connecting panel 4 and the pin 5 and the groove of the panel 9 closely rests on the pin 5. In addition to anchoring the VIP panels and VISE composite panels, they are at the same time glued to the base of the wall or wall. The 5 anchor pins extend into the grooves 9, which are already factory-made in the thermal insulation panel.

Figure 4 shows a double pin anchor 6 consisting of a base plate 2 with holes for screws 3, connecting plates 4, pin 5, additional connecting plate 7 and additional pin 8, the base plate 2 and both pins 5, 8 They are parallel to each other and in the upper part of the anchor, the upper line of the pin 5 is below the plane of the holes of the screws 3, the upper line of the additional pin 8 is generally below the upper line of the pin 5, and consequently the line of the additional connecting plate 7 is below the line of the connecting plate 4, also due to weakening thermal bridges, and is the width of the anchor or. of the connecting plates 4, 7 depends on the position of the grooves 9, 12 in the thermal insulation boards 10, 11 and. indirectly from the thickness of the thermal insulation.

Figures 5a, 5b, 5c and 5d show the fastening in the case of double-pin anchors 6, where the procedure is exactly the same as for single-pin anchors 1, except that a second layer of thermal insulation 11 follows. These panels, which also have grooves 12 , slots 12 into the additional pins

8. If necessary, the individual layers of thermal insulation boards will adhere to each other. 5a and 5b show the fastening method when the two thermal insulation panels are made with grooves, such that when installed, the first thermal insulation panel 10 with a part between the inner side of the panel adjacent the wall and the groove 9 in the space between the connecting plate 4 and pin 5 and groove of panel 9 closely adjacent to pin 5 and a second thermal insulation panel 11 having a portion between the inner side of the panel which, adjacent to the first thermal insulation panel 10 and groove 12, fits tightly into the space available between the additional connecting plate 7 and the additional pin 8 and the groove 12 of the plate 11 rests tightly on the additional pin 8.

Figures 5c and 5d show the attachment method when the first layer of thermal insulation of the VIP or VISE panels has no grooves. The grooves 12 are made on the second layer of thermal insulation adjacent to the additional pin 8. In this case, the thermal insulation panel 10 fits closely into the space between the connecting plate 4 and the pin 5 and the second thermal insulation panel 11 fits tightly into the space between the additional connecting plate 7 and the additional pin 8 and the groove 12 of the plate 11 closely rests on the additional pin 8.

Figure 6 shows a schematic view of one of the mounting methods showing the placement of anchors 1 or 6 with respect to thermal insulation boards.
