Description of the invention

Technical field

[0001] Modular sandwich panels, sealing, building envelopes, air tightness, water tightness, drainage, water pressure decompression

Technical problem

[0002] Modular sheathing systems consist of individual modules - elements that are attached to the supporting structure and are mutually sealed. The durability of such systems is highly dependent on the durability of the individual elements and the installation conditions, which also include the influence of the human factor that affects the realization of current functionality requirements. The installation conditions of modular panels on the construction site are, as a rule, external weather conditions, the duration of which during the installation of modular panels in the entire system with multiple functional sheaths is measured in hours and therefore they are variable Under different external conditions. individual components of assembled modular panels behave differently - such as deviations in tolerances due to different temperatures, etc.

[0003] Effects due to changing conditions are then reflected in the dimensional and relative position of one modular panel in relation to another.

[0004] In practice, this means that with certain details and locations of buildings, local irregularities appear, which when applied are reflected in the sitting

• penetration of water into the joints of modular cladding elements

• leakage of water into spaces with installations

• condensation in the joints between elements

• reduction of thermal insulation or vapor-thermal insulation

faster deterioration of materials and installed components

higher energy consumption for heating and cooling rooms (higher costs)

a shorter period of use of the building envelope

[0005] The next problem with the solutions known so far is the application of cladding made of modular sandwich panels in the corners, and panels that are curved and overlap, as well as the subsequent coloring of the cut edges, which poses the problem of impermeability! for water and air in the corner. risk of corrosion and a less aesthetically pleasing product Cutting and bending, which are usually done with the help of a device, the insertion of sealants and painting usually depend on the dexterity of the human hand and present a risk of later leakage and/or corrosion of the cut sheet metal on the corner

State of the art

[0006] Despite this problem, the outer envelope of the building must ensure safety and protection against external influences, among which are bearing capacity (load from the external environment, such as wind, snow, and its own weight, etc.), impermeability to water and air, thermal insulation and fire safety. On the other hand, users expect to see a different exterior configuration

- architectural solutions. aesthetics

[0007] Basically, there are two types of building envelopes combined building envelopes consisting of

(viewed from outside to inside)

cladding, supporting structure cladding, air space vapor-permeable film, thermal insulation and bearing wall of concrete, brick or various bearing panels Installation of such building envelopes is usually carried out on the building They are also called "Build Up Systems", which need a bearing wall for stability. These systems meet load-bearing requirements only on load-bearing walls or with the installation of an additional substructure. They meet the requirements of water tightness and thermal insulation, but additional risks appear due to external influences and the effect of the human factor during installation and only for certain types (methods) of installation. They do not meet, or meet to a much lesser extent, the requirements regarding air tightness and fire safety and are therefore primarily used as decorative elements of building envelopes with limited functionalities. modularity on the facades

[0008] Building envelopes made of linear prefabricated sandwich panels that consist, viewed from the outside to the inside, of a composite sandwich panel and a basic structure made of steel, concrete, and wood. The composite sandwich panel is made in production and delivered as such to the construction site. where as self-supporting elements, they take over the external loads themselves. The filling is made of an insulating core, so they have an appropriate degree of thermal insulation and. in the case of a non-combustible insulating core, also the required fire resistance When it comes to linear prefabricated sandwich panels, there are usually seals already installed in the vertical joints to ensure tightness! for water and air In the transverse joints of such sandwich panels, sealing material is not installed during the production phase, so the problem of sealing quality and durability remains due to external influences and the effects of the human factor during installation. These systems have the disadvantage that, as linear components, they are less suitable for modular installation, because they do not meet the requirements of the architects regarding the perfect appearance of the modules - raster on the facades (longitudinal and transverse deep channel

- fugue. which breaks the facade into a grid of different or the same modules)

[0009] EP1301668B1 describes a sandwich panel according to the preamble of claim 1

The essence of the invention

[0010] The modular system of sandwich panels and its installation procedure in the multi-functional lining of the building (Figure 1) solves the above-mentioned technical problem. It is self-supporting and does not require load-bearing walls or additional substructures, while at the same time meeting the requirements in terms of fire resistance, impermeability! for air and water and thermal insulation, without additional risks of external influences and effects of the human factor during installation with different types (methods) of installation. Likewise, the seals are installed during the production phase, which solves the technical problem of the quality and durability of the sealing due to external influences and the effect of the human factor during installation.

[0011] The present invention has achieved all the functionalities of an integrated prefabricated modular panel and installation system that provide a high degree of durability for different types and methods of installation, which largely prevents the influence of the human factor and external influences on the durability of the building and the reduction of its functionality. the aesthetics of the corners and channels, which define the module in the transverse and longitudinal direction In the prefabricated and modular panel element (Fig. 3), all seals are also inserted in the longitudinal joints, as well as in the corner joints, which are key elements for air and water tightness of facades in different directions and which have been specially developed for this purpose. modular panels and fast and easy installation. Sealing in the transverse direction between adjacent modular panels is achieved using specially designed seals. which are installed during assembly assembly Sealing of joints between panels is not new, however, the shape of the seal is such that it compensates for differences in elongation due to temperature effects on the facade, and also compensates for permitted tolerances during installation. The seals are constructed in such a way that it is possible to easily insert decorative slats, channels for lighting, additional decoration in the channels, which can have different colors, shapes, materials and lighting, which allows architects additional combinations when designing facades and aesthetic solutions for modular panels and decorative slats.

[0012] The modular sandwich panel is the basic element of the building envelope. It is made in different thicknesses (from 50 to 250 mm) depending on the requirements for thermal insulation, fire resistance and other technical characteristics. The width of the modular sandwich panel is subject to limitations depending on technology and means of transport, but is usually between 500 and 1200 mm. The length of a modular sandwich panel depends on technology and transport constraints, and is usually between 500 mm and 14 m. The invention solves the above-mentioned problems independently of the different dimensions of modular sandwich panels. The modular sandwich panel basically consists of a bottom plate 9, a seal 10 of the inner joint, an insulating core 8, a cover 5, a seal 11 of a longitudinal joint on the outside, a "male" corner seal 6, a "female" corner seal 7 and other parts listed below that represent parts integrated into the cover. The installation of modular sandwich panels 1 is performed in a simple and robust way, because the modular sandwich panel 1 contains all the necessary and already integrated components during production for greater functionality, except for the solid screw 2, the gasket 4 for the transverse connection and the decorative slats for the longitudinal connection 3 or the decorative profile in the transverse connection 404 that should be inserted into the assembly during installation, i.e. the fastening of the modular sandwich panels Installation system due to the invention, which is described below, can be performed as shown in figure 1 In the plane of the facade, it can be parallel, staggered, placed horizontally, placed vertically or placed at any oblique angle 15. Also, the invention allows the installation of the invention on non-vertical walls of the facade, which can be planes that are inclined forward or backward (at angles from + - to 45 degrees) The modular sandwich panel can be made to have a curved shape, which allows the realization of a system with a curved modular cladding of the building - the invention solves this problem with essential elements of modular sandwich panels - corners and joints of 4 panels

[0013] The cover 5 of the modular sandwich panel is made by bending and deep drawing technology. The invention solves the design and shape of the corner 501 of the cover with a corner radius of 3 to 150 mm and a corner height of 10 to 40 mm. in combination with specially shaped corner seals 6, 7 The cover is made of painted or unpainted metal sheet of steel, aluminum, stainless steel or other metal materials, and thickness from 0.5 to 12 mm. A specially shaped channel 503 extends along the cover, which represents the longitudinal most important characteristic of the module for the facade made of modular sandwich panels. The channel which on the facade of the modular panels represents the width and depth of the longitudinal groove, or. the joint has an arbitrary width, but in order to achieve the appropriate effect of light and shadow, it is wide from 20 - 30 mm, and in this version?bmm and deep from 15 to 30 mm, and in this case 25 mm. On the cover there is a similar transverse channel 504 with the width or depth of the joint, which represents the main transverse characteristic of the facade module from modular sandwich panels. The subject of the invention is also that the sheet in both channels is shorter than the length or width of the cover, which is in the optimal range of the missing material between 30 and 200 mm (x), which allows the production of high-quality corners and the adjustment of all sealing and other elements that make up the cover and the lower part plates in order to ensure a high degree of impermeability. At the end of the longitudinal channel, a special recess 502 with a depth of 1 to 5 mm is made, which enables the appropriate connection of the corner seals 6 and the cover 5 in the longitudinal joint. Likewise, the shape of the corner seals 6.7 is specially designed so that it "grabs" the sheet metal on the lower cut of the corner in the dry part and thus protects it from external influences, such as moisture. Before assembling the corner seals 6 or 7, a sealing material is applied to the surface of the joint, which compensates for the differences in the tolerances of the manufactured corner 501 of the cover and the corner seals, and ensures the complete tightness of the joint even in the production phase. On the left side of the cover are seals that look like a "male" joint - corner seals 6. while on the other part of the cover seal, seals are placed that have the form of a "female" joint - corner seals 7. Both corner seals are protected from falling out until the time of assembly by a glued joint, which is performed during the assembly of the seal with the cover during production. The corner seals 6, 7 are made of material (rubber, synthetic materials for sealing, combination of materials and hardness of the material), which has an adjustable stiffness, defined by the interval from 40 to 90 Shore, while at the same time the contact points are elastic enough to allow a high degree of adjustment at the joints, i.e. contacts with other seals and the cover U with our tests, we determined the functioning of elements 6.7 at hardnesses from 40 to 90 Shor.

[0014] The system of the specially constructed cover 5 of the corner 501 of the cover and the system of seals are adapted to all contact tolerances and ensure a very high degree of impermeability - impermeability to water at a pressure difference of 600 Pa (up to 1500 Pa). the seal is inserted into the cover at the joint of the longitudinal channel 503 of the cover, a custom joint is formed, and at the same time the longitudinal seal 11 is caught in the longitudinal channel of the corner seal 7. This establishes the tightness of the joint between the longitudinal channel and the corner of the cover. during the joining of two adjacent panels, the seal 10 of the inner joint is caught in the joint. This seal is inserted into the panel during the production phase - The inaccurately installed initial and final position of the longitudinal seal 11 is compensated by the so-called membrane (hollow space) 702 installed in the corner seal 7. At the place where the longitudinal seal 11 is located, the membrane 702 in the corner seal 7 is moved inward by a thickness gaskets and thus allows compensating for the additional thickness of the gasket in the joint and ensures the sealing of the facade. To ensure the functionality of the membrane, the optimal thickness of the membrane is between 0.3 mm and 2 mm, and the stiffness is between 20 and 90 Sh for rubber. 30 Sh for rubber The thickness of the soft part is from 1 to 10 mm in order to compensate for the different thicknesses of the longitudinal seals at the end of the longitudinal joint.

[0015] Since the seal can be made of different materials (EPDM rubber, silicone rubber, butyl, etc.), then different degrees of vapor impermeability can be achieved. and thereby preventing the entry of warm air into the joint, thus preventing the occurrence of excessive condensation.

[0016] Sealing (tightness for air and water) in the transverse direction of the modular panels is realized with the seal 4 of the transverse joint which covers the area of the width of the vertical joint, or. groove 14 between 15 mm and 30 mm. This seal has a special shape and contains materials of different degrees of stiffness, ie. adaptability. The base part of the 401 gasket. which is of a harder material (hard rubber, etc.) with a hardness between 40 and 90 Shore, has a bearing function, while the lower tab 403 of the seal provides protection against the seal falling out. The softer gasket insert 402, with a hardness of 10 to 30 Shore, has the function of a labyrinth seal that can be adapted to different widths of the groove (compensating tolerances) and thus prevents the penetration of water into the transverse joint of the modular panel 1 by decompressing the water pressure. With this shape of the opening, the pressure force is always constant, which extends the life of the seal and the sealing function. The joint of corner seals 6 and 7 can be easily moved due to the tolerances in the length of the modular panels, as well as due to the tolerances during attachment. is adapted to the sealing surface of the labyrinth seal 402 of the cross-joint during the insertion of the cross-joint seal 4 and thereby creates a continuous sealing surface and ensures a high sealing quality even in cases of deviations that are common during the assembly of modular sandwich panels. The thin flexible lamella 703 has a variable thickness from 0.1 mm to 3 mm, width from 0.1 to 30 mm and length from 5 to 150 mm and serves to cover the lamella 603 on the adjacent corner element, which has similar dimensions to the lamella 703, and together they serve to cover the transverse movement of the corner elements, or the panel. The optimal width of the lamella depends on the type of transverse seal and can be 300 mm wide for appropriate situations, i.e. required sealing properties. At the junction of the four panels/corner elements, there are asymmetrical lamellas described above (4 in total) on both sides, which are used for continuous overlap of the elements and provide an excellent sealing surface for the transverse seal.

[0017] The seal of the cross connection in the harder part 401 of the seal has a derived channel for inserting decorative profiles or other accessories on facades made of modular sandwich panels.

(elements for lighting, etc.)

[0018] In the cover 5 of the modular sandwich panel 1 in the channel of the longitudinal joint 503, the supports of the decorative slats 13 are installed according to a certain arrangement by the technological process of deformation with cold joining. The subject of this invention is also the assembly principle, which ensures that there is no penetration through the surface of the cover - it is only adjusted. which enables impermeability to water and air and at the same time the required load capacity of the decorative slat support itself. Deformation of the cover sheet 5 is without penetration, i.e. it is impermeable to water and air. and the support changes into a head-like shape by deformation and is inserted into the deformed metal sheet and thus acquires load capacity

[0019] In the cover 5 of the modular sandwich panel 1, the fastening profile 12 is installed in the channel 504 of the transverse connection in a certain order by the technological process of deformation 121 with cold joining, so the said channel is impermeable to water and air. but in this version there is a novelty due to the very accurate placement and the use of automated technology that allows the assembly to be robotic. The fastening of the panels is achieved by a special joint with the overlapping of metal sheets, with the support of one part with wool and the screwing of screws through the lower metal sheet, so that it represents a cross joint that has a high load capacity when using the optimal amount of material. Our research has shown that for the same load capacity, a continuous fastening profile is not needed across the entire width of the panel. but that the optimal length of each individual fastening profile 12 at the fastening point is 150 mm.

[0020] The prefabricated modular sandwich panel 1 in this way ensures a high degree of self-support, water and air tightness, the required degree of resistance to heat and fire, and superior aesthetics. A high degree of repeatability of quality is ensured due to stable production conditions in an industrial environment. The specially formed corner 501 of the cover of the modular sandwich panel solves the problem of weak points for corrosion and aesthetically unpleasant cuts and seals on the corners of the cover that are connected to the "build up" system of the envelope. it also enables quick installation with minimal impact on durability due to the risk of external influences and the influence of the human factor during assembly. The system was developed to enable automated assembly

[0021] The installation system of modular panels also allows aesthetic diversity due to the possible combinations of modular panels with different laying lines and inserted slats or other optional decorative elements, which can be easily installed in the grid channels between the modular panels. Since the modular panel has a high degree of self-support. then no additional substructure is required, unless the basic structure does not correspond to the architectural solution of the raster grid

[0022] This invention reduces the effects of external influences and the human factor during assembly on durability and the consequent risk of

• moistening of the insulation in case of rain during installation

of water entering the panel joints or even inside the building due to the human factor during the execution of the works

• condensation in the joint in case of non-quality execution

reduction of the functionality of thermal insulation and waterproofing due to the reasons mentioned above

occurrences of corrosion at the corners of the covering - an aesthetic and functional defect that reduces the utility value of the building envelope for the customer due to the aforementioned reduced

functionality.

[0023] Corner sealing elements are inserted into the corners of the outer panel, in which a so-called membrane is installed, which compensates for the imprecisely installed initial and final position of the longitudinal seal. Asymmetric lamellas (603, 703) are integrated on the corner elements, on which the longitudinal movement is reflected in the relative relative position of the movement of the two feathers on the corner elements, but since the feathers are thin and elastic, when the third element is inserted, it (of the transverse sealing profile) bend towards the inside, thus forming a vertical continuous sealing surface. The transverse sealing profile contains a drainage groove 406 for decompressing the water pressure and the primary removal of water (drainage), and a drainage channel 405, which in case of water leakage next to the sealing profile collects said water and drains it out of the building envelope system vertically downwards

[0024] The invention is described in more detail below on the basis of exemplary embodiments and attached drawings, wherein the drawings are part of this patent application, and the drawings show

Figure 1 shows different assembly procedures of the modular facade system with modular sandwich panels 1 that can be installed at different angles 15 and have a transverse seal 4 and a longitudinal decorative strip 3 in the transverse joints 14

[0025] In a preferred embodiment, the modular sandwich panel 1 contains a bottom plate 9, an internal joint seal 10, an insulating core 8, a cover 5, a longitudinal joint seal 11 on the outside, two "male" corner seals 6, two "female" corner seals 7, and the remaining parts that are integrated into the cover.

[0026] The installation of modular sandwich panels 1 is carried out in a simple and robust way, because the modular sandwich panel 1 contains all the necessary and integrated components during production for greater functionality, except for the fastening element itself - the screw 2 of the gasket 4 for the transverse joint and the decorative slats 3 for the longitudinal joint or the decorative profile in the transverse joint 404, which should be inserted during assembly, i.e. during the fastening of the modular sandwich panels

[0027] In the plane of the facade, the mounting system can be parallel, staggered, placed horizontally, placed vertically or placed at any oblique angle 15 In the vertical grooves 14, a seal for the transverse connection 4 is placed, whereby the basic part 401 of the seal is made of a harder material (hard rubber or similar) and this part has a bearing function, and the lower tab 403 of the seal provides protection against the seal falling out, while the softer 402 seal cartridge has a labyrinth seal function that can be adjusted to different groove widths. The transverse sealing profile has a drainage groove 406 for decompression of water pressure and primary water removal (drainage), and a drainage channel 405, which in the event of a water leak next to the sealing profile, collects said water and takes it out of the building envelope system vertically downwards.

[0028] The cover of the modular sandwich panel 5 is produced using a special technology and solves the execution and shaping of the corners 501 of the cover of the modular sandwich panel in combination with specially shaped corner sealing elements. The cover 5 is produced from a thin colored metal sheet. Along the cover there is a specially designed channel - longitudinal joint 503, and on the cover there is a transverse groove 504, which is made similar to it. At the exit of the longitudinal joint 503, a special recess 502 is made in the metal sheet, which allows for a customized connection of the corner elements and the cover 5 in the longitudinal joint

[0029] The imprecisely installed initial and final position of the longitudinal seal 11 is compensated by the mentioned membrane 702, which is installed in the corner seal. On the corner seal, lamellas 603 and lamellas 703 are also integrated, which are adapted to the sealing surface 402 of the cross joint when inserting the seal 4 of the cross joint.

[0030] In the cover 5 of the modular sandwich panel 1, the fastening profiles 12 are installed in the channel 504 of the transverse connection according to a specific arrangement with the use of a special system of fixing - fastening 121 of the fastening profile, while the supports of the decorative slats 13 are installed in the channel 503 of the longitudinal connection.
