Abstract

The introduced invention of a modular sandwich panel and its installation system into a functional building panelling is self-supporting and does not require a supporting wall or additional subassembly, while at the same time it meets the requirements regarding fire resistance, air tightness, water resistance and thermal insulation without any additional risks due to external impact and human factor influences during the installation in various directions (methods). At the same time the sealing is already installed during the making which solves the problem of quality and durability of the sealing due to external impact and influences of human factor during installation. The modular sandwich panels are as line elements suitable for modular installation since they meet the requirements of the architects regarding perfect look of the modules - grids on the facades. The modular sandwich panel (1) consists of a base sheet-metal panel (9), a sealing of the internal seam (10), an insulation core (8), a cover (5), a sealing of the longitudinal seam on the external side (11), two male corner elements (6), two female corner elements (7) as well as other parts, which are integrated parts inside the cover. In the prefabricated element of the modular panel there are also all longitudinal washers of longitudinal seams integrated and also on the corner seams, which are key elements for the air and water tightness of the facade in various directions and have been developed especially for this purpose. Apart form this, reinforcement elements are integrated into the prefabricated modular panel in the transverse direction, which enhance the self-supporting features of the modular panel and their quick and simple installation.

View the problem

Modular building envelope systems consist of individual modules - elements that are attached to a supporting structure and are sealed with one another. The durability of such systems strongly depends on the durability of the individual elements and conditions of installation, which include the influence of the human factor, which affects the achievement of actual functionalities according to requirements. Installation conditions of modular panels on a construction site are usually external weather conditions, which, when assembling modular panels into a whole system of multiple functional linings, take a long period of time and are therefore quite variable. Under different external conditions, the individual components of composite module panels also behave differently - e.g. deviations in tolerances due to different temperatures, etc.

Impacts due to variable conditions are then reflected in the dimensional and relative displacements of the position of one module board relative to the other. As a result, there are inaccuracies and additional risks to reducing the durability and individual functionality of the building finishes.

In practice, this means that certain details or locations of the building envelopes lead to local irregularities, which are reflected in use as:

• penetration of water into the joint of modular envelope elements • displacement into the premises of the building • appearance of condensation in the joints between elements • reduction of thermal insulation due to moistened thermal insulation • faster decay of embedded materials and elements • higher energy consumption for heating and cooling the premises (higher costs) • shorter useful life the value of the object wrapper

Another problem with the solutions known so far is the construction of a modular sandwich panel cover in the corner with curved and folded sheets and subsequent painting of the cut edges, which presents a problem of water and air in the corner, the risk of corrosion and aesthetically less quality product. Notching and bending are otherwise carried out by means of devices, and the insertion of sealants and painting is usually dependent on the skillful human hand and poses a risk of consequent misalignment and / or corrosion on the sections of the cover corner sheets.

The state of the art

The outer envelope of the building for the problem under consideration must provide security and protection against external influences, which include load capacity (loads of the external environment such as wind, snow, own weight, etc.), water and air tightness, thermal insulation and fire safety. Users also expect the design of an exterior - an architectural solution, an aesthetic.

There are two types of object wrapping:

composite envelopes of structures consisting of from the outside: cover, load-bearing structure of cover, air space, vapor-permeable foil, thermal insulation and load-bearing wall of concrete, brick or various load-bearing panels. The assembly of such object wrappers is usually performed on the object. These are the so-called "Build Up Systems" which require a load-bearing wall for stability. These systems only meet the load-bearing conditions of the load-bearing walls or the installation of an additional substructure. They meet the requirements for waterproofing and thermal insulation, but with the additional risks of external and human factors during installation and only in restricted installation directions (modes). They do not meet or to a much lesser extent the requirements for airtightness and fire resistance, so they are used primarily as decorative elements of the building envelope with limited functionality. The cover, which, when mounted on the building, is mounted on the lower composite thermal insulation, which meets the requirements of architects for the external appearance of modularity , on the facades of the pre-fabricated liner sandwich panels, consisting of exterior inwards: composite sandwich panel and basic construction of steel, concrete, wood ... The composite sandwich panel is made in production and is brought to the building as such. Sandwich panels are mounted directly on the main structure or on an existing wall, taking over the load of the external loads as self-supporting elements, so they are already load-bearing. The filler is from an insulating core, so they already have the appropriate level of thermal insulation and, in the case of non-combustible insulation cores, the required fire resistance. Since these are line-made elements of sandwich panels, longitudinal joints usually include seals to ensure watertightness and airtightness. In the transverse joints of such sandwich panels, however, the sealing is not incorporated at the stage of manufacture, so the problem remains of the quality and durability of the sealing due to external influences and human factor influences during installation. These systems have the disadvantage that they are less suitable for modular installation as line elements, because they do not meet the requirements of architects for the full appearance of the modules - facades (longitudinal and transverse deep grooves that break the facade into a raster grid of different or identical modules) ).

Description of the new solution

The present invention of the modular sandwich panel and its system of multi-functional building lining (Figure 1) is self-supporting and does not require a load-bearing wall or additional substructure, while meeting the requirements for fire resistance, airtightness, water-tightness and thermal insulation without additional risks due to external the effects and effects of the human factor during installation in different directions (modes) of installation. Also, the sealing is integrated in the manufacturing phase, which solves the technical problem of the quality and durability of the sealing due to external and human factors during installation. Modular sandwich panels are suitable for modular installation as line elements, since they meet the requirements of architects for the full appearance of the modules - spread on the facades.

The present invention provides all of the aforementioned functionalities in an integrated prefabricated modular board and mounting system, which provides a high degree of durability in different directions and mounting methods, while greatly preventing the impact of human factors and external influences during construction on durability and reduction of any functionality. The modular panel element is fully pre-fabricated under stable conditions of the internal (industrial) environment, with the panel cover being manufactured using a special technology that meets the highest requirements for modularity in the form of raster nets and the high aesthetics of corners and channels defining the module in the transverse and longitudinal direction. The prefabricated element of the modular panel (Figure 3) already includes all the seals of the longitudinal joints, as well as the corner joints, which are crucial elements for the air and watertightness of the facade in different directions and specially developed for this purpose. In addition, the pre-fabricated modular plate also incorporates reinforcing elements in the transverse direction, which contributes to the modular plate's self-support and quick and easy installation. Sealing in the transverse direction between the individual modular panels is made using specially designed seals that are mounted on the assembly. The sealing of the contact between the panels is not new, but the shape of the sealing itself is adapted to absorb differences in elongation due to the temperature effects on the facade, while also compensating for the tolerances allowed for installation. The seals are designed in such a way that it is easy to insert decorative slats, light channels, additional channel decorations, which can be of different colors, shapes, materials or lighting, thus providing architects with additional combinations of facade appearance and aesthetic solutions between modular panels and decorative slats.

A modular sandwich board is a basic element of a building envelope. It is made of 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 conditioned by the technology and restrictions of the means of transport, and is usually between 500 and 1200 mm. The length of the modular sandwich panel depends on the technology and the restriction on transportation,

Λ · is usually between 500 mm and 14 m. The invention solves the problems described below independently of the said dimensional variables of the modular sandwich panel. The modular sandwich panel consists essentially of the lower sheet 9, the seal of the inner joint 10, the insulating core 8, the lid 5, the longitudinal joint seal on the outside 11, the corner seal - "male" 6, the corner seal - "female" 7 and other parts , which are listed below as integrated components in the hood. The installation of modular sandwich panels 1 is carried out in a simple and robust way, since the modular sandwich panel 1 contains all the necessary and integrated elements for more functionality except the fastener itself. screws 2, cross joint seals 4 and decorative slats for longitudinal joint 3 or decorative profile in transverse joint 404 to be inserted at installation or. attaching a modular sandwich panel. The mounting system can be optional as shown in figure 1 because of the invention described below. In the plane of the facade, it can be parallel, stepped, horizontally positioned, vertically positioned, or laid at any oblique angle 15. Also, the invention allows installation vertical facade walls are therefore oblique planes of the facades with inclination forwards or backwards (+ - angles up to 45 degrees). The modular sandwich panel can also be made in curved form, which enables the implementation of the curved modular building panel system. The invention solves this problem in an essential element of the modular sandwich panel - the corners and junction of 4 panels.

The lid of the modular sandwich panel 5 is made using bending and deep drawing technology. The invention solves the design and shape of the corner 501, wherein the radius of the corner is from 3 to 150 mm and the height of the corner is between 10 and 40 mm, in combination with specially designed sealing elements of the corner 6, 7. The cover is made of thin colored or unpainted sheets of steel, aluminum, stainless steel or other metallic materials, from 0.5 to 1.2 mm thick. Along the lid there is a specially shaped channel 503, which represents the longitudinal emphasis of the modular facade sandwich panel module. The channel that represents the width and depth of the longitudinal joint on the facade of modular panels is arbitrarily wide, but from the aspect of achieving the effect of shadow and stress of the joint it is in width from 20 to 30 mm in the case 25 mm and depth from 15 to 30 mm in the case 25 mm. . However, a similar transverse groove 504 with the same widths or depths of joints is formed transversely to the cover, which represents the transverse emphasis of the sandwich panel module on the modular facade. It is also an object of the invention that the sheet metal in both molded ducts is shorter than the length or width of the cover, which is in the optimum area of missing material between 30 and 200 mm (x), which enables the quality of the corner and the adjustment of all the sealing and other components that make up the hood and the bottom of the panel provide a high degree of tightness. At the expiration of the longitudinal duct, a special imprint is formed in sheet metal 502 1 to 5 mm deep, which allows for custom contact of the corner seal 6 and the lid 5 in the longitudinal contact. Also, the shape of the corner gasket 6.7 is specially designed to "catch" the sheet metal on the lower section of the corner into the dry part and thus protect it from external influences of moisture. Before assembling the corner seal 6 or 7, a corner seal is applied to the surface - a sheet of sealant is applied to compensate for differences in the tolerances of the manufactured corner 501 and the corner seal and to ensure complete contact tightness already in the production phase. On the left side of the cover are gaskets having the form of "male" contact - corner seal 6, and on the other part of the cover are inserted gaskets having the form of "female" contact - corner seal 7. Both corner seals are protected against failure until the time of installation with a glued joint that is made during the assembly of the seals with the lid in production. The corners of the corners 6, 7 of the cover are made of a material (rubber, synthetic sealing materials, a combination of materials and hardnesses of materials) that is rigid, defined by an interval of 40 to 90 Shor, while being flexible enough to allow a high degree of contact adjustments on contacts with other seals and cover. Our tests have found that the functioning of the elements 6, 7 is at 40 to 90 Shor hardness. In our embodiment, we get the best 70 Shore results.

A specially designed cover 5 or corner of the cover 501 and a sealing system that adapts to all tolerances and ensures a very high degree of watertightness at a pressure difference above 600 Pa (up to 1500 Pa). As indicated, the corner seal 6 or 7 is inserted into the corner of the lid 501 with an additional seal kit and temporarily glued to the lid. By inserting a corner seal into the lid at the contact of the longitudinal duct of the lid 503, it establishes an adaptive joint, and at the same time captures a longitudinal seal 11. It seals the longitudinal seal between the longitudinal duct and the lid corner. The tightness in the contact between two adjacent modular panels is created by the specially designed geometry and the adaptive joint - the "perforation" principle. At the same time, when assembling two adjacent panels, a seal of the inner joint 10 is secured into the joint, allowing tightness on the inside. This seal is also inserted into the panel at the production stage. The inaccurately mounted start and end position of the longitudinal seal 11 is compensated by a so-called diaphragm (hollow opening) 702 in the corner element 7. At the location of the longitudinal seal 11, the diaphragm 702 in the corner element 7 is displaced by the thickness of the seal inside, thereby compensating the additional thickness of the seal in the joint and ensures the sealing of the facade. To ensure the functionality of the membrane, an optimum membrane thickness of between 0.3 and 2 mm, having a hardness of between 20 and 90 Sh for rubber material, is optimal. Instead of mounting the membrane, the same transition effect of the longitudinal joint described above can be achieved by using materials with different hardness. The hard part of the corner element has a hardness of between 40 and 90 Sh for the rubber material, the softer part is made of a hardness of between 15 and 30 Sh for the rubber material. Soft part thickness from 1 to 10 mm to compensate for different thicknesses of longitudinal seals at the end of the longitudinal joint.

Since the seal can be made of different materials (EPDM rubber, silicone rubber, butyl, etc.), it achieves a different degree of vapor tightness, thus preventing hot air from entering the joint and preventing condensation.

Sealing (airborne and waterborne) in the transverse direction of the modular panels is ensured by the seal of the transverse joint 4, which covers the width of the vertical joint 14 between 15 and 30 mm. This seal has a special shape and is composed of materials of varying degrees of rigidity or flexibility. Thus, the base portion of the seal 401 is of a harder material (hard rubber or the like) with a hardness between 40 and 90 Shore having a bearing capacity, the lower lip of the seal 403 having the function of holding the seal against failure. The softer insert of seal 402 with a hardness of 10 to 30 shore has the function of a labyrinth seal which adjusts to the different joint width (compensates for tolerances), thus preventing water from entering the transverse joint of modular panel 1 by decompression of water pressure. With the design of the opening, the compressive force is always constant, which extends the life of the seal and the sealing function. The assembly of the corner seals 6 and 7 may be slightly offset by the tolerances in the length of the modular plates and also by the fixing tolerances. The invention solves the problem of sealing at the cross connection of the joint of four panels with a special form of corner seal having a thin flexible membrane 703 on the surface of the transverse contact of the modular sandwich panels. The membrane 703 is adapted to the sealing surface of the maze of the transverse contact 402 and s by inserting this creates a continuous sealing surface and ensures high-quality sealing even in the case of tolerances that are acceptable and normal when installing modular sandwich panels. The thin flexible membrane 703 has a variable thickness of 0.1 mm to 3 mm, a width of 0.1 to 30 mm and a length of 5 to 150 mm and serves to cover the membrane on the adjacent corner element 603, which is similar in size to the membrane 703 ' overlapping the transverse offset of the corner elements or. plates. The optimum width of the membrane depends on the type of transverse seal and can be up to 30 mm wide for each situation or situation. required tightness. At the junction of the 4 panels / corner elements, the asymmetrical diaphragms described above (in total 4) are described in cross-section on both sides, which serve as a continuous passage of the elements and provide an excellent sealing surface for the transverse seal.

In the hard part of the gasket 401, the transverse joint gasket has a duct for inserting decorative profiles or other accessories on the facades made of modular sandwich panels (light elements, etc.).

In the cover 5 of the modular sandwich panel 1, beams of decorative laths 13 are installed in the channel of the longitudinal contact 503 according to a certain schedule by cold-forming process. The object of the invention is also the principle of installation, which ensures that the sheet metal is not pierced but only adapted, which enables watertightness and airtightness and at the same time the required load-bearing capacity of the bracket bracket itself. The transformation of the sheet metal of the cover 5 is without punctures, that is, waterproof and airtight, and the carrier is trapped into the transformed sheet by means of transformation into a "head" and thus is load-bearing.

In the cover 5 of the modular sandwich panel 1, a fixing profile 12 is installed in the cross-section channel 504 according to a certain arrangement, by means of a cold-coupling process 121, which is waterproof and airtight. The mounting profile 12 thus affixed serves to carry the load of the mounting point. This otherwise known solution is, in the present case, an invention due to the very accurate layout and layout of the automated technology, which allows the assembly to be robotized as well. The panel is fastened with a special joint with the cover sheets, and the support of one part with wool and screwing through the bottom sheet is a high load-bearing cross-link for optimal material consumption. The study found that for the same load capacity (no continuous mounting profile is required over the entire width of the panel, but the optimum length of the individual for the rigid profile 12 at the attachment point is 150 mm.

The prefabricated modular sandwich panel 1 thus manufactured provides a high degree of self-support, water and air tightness, the required degree of heat and fire resistance and superior aesthetics. A high degree of reproducible quality is also ensured due to stable manufacturing conditions in an industrial environment. The specially designed corner of the lid of the 501 modular sandwich panel also solves the problem of the weak spot for corrosion and the aesthetic inadequacy of cuts and seals at the corners of the lid with respect to the "build up" cover system.

The modular board mounting system ensures a high degree of air and water tightness in all directions and mounting modes, and allows for quick mounting with minimal risk of sustainability impacts due to external influences or human factors during mounting. The system is designed to allow for automated assembly.

The modular panel mounting system also provides aesthetic diversity due to the possible combinations between modular panels with different laying directions and intermediate slats or other possible decorative elements that are easily integrated into the raster mesh channels between the modular panels. Because the modular board has a high degree of self-support, no additional substructure is required, unless the main structure does not fit the architectural design of the raster grid.

The invention prevents the effects of external influences and the human factor during installation on durability and consequently risks for:

Isolation of insulation in case of rain during installation

- Intrusion of water into the joint of the panel or even inside the structure due to the human factor during execution

- Condensation in the joint in case of poor performance

- Decrease in functionality of thermal insulation and watertightness for the reasons stated above

- Corrosion on the corners of the lid - aesthetic and functional defect

- Lower usable value of the object wrapper for the customer due to the stated reduced functionality

In the corners of the outer panel are sealed corner elements into which a so-called diaphragm is installed, which compensates for the inaccurately mounted initial and final position of the longitudinal seal. The asymmetric tabs are integrated on the corner elements, on which the longitudinal offset reflects the relative offset of the two feathers on the corner elements, but because the feathers are thin and elastic, they bend inwards when the third element (transverse sealing profile) is inserted, forming a vertical continuous seal. surface. The transverse sealing profile has a drainage groove 406 for decompression of water pressure and primary drainage (drainage), and a drainage channel 405 which, in the event of any leakage of water past the sealing profile, collects this water and guides it downward from the building envelope system.

The essence of the invention is explained in more detail below with a description of an embodiment and the accompanying drawings, the drawings being part of the present patent application and the drawings show:

Installation of modular sandwich panels 1 is carried out in a simple and robust way, since modular sandwich board 1 contains all the necessary and integrated elements for more functionality except the fastener itself - screw 2, cross joint seals 4 and decorative slats for longitudinal joint 3 or decorative profile in cross-section 404 to be inserted when assembling or attaching a modular sandwich panel.

The mounting system is in the plane of the facade, which can be parallel, stepwise, horizontally positioned, vertically positioned or placed at any oblique angle 15. In the vertical joints 14, a seal for the transverse joint 4 is installed, the base part of the seal 401 being of a rigid material ( hard rubber or the like) and has a load bearing function, the lower lip of the seal 403 has the function of holding the seal against the drop, and the softer insert of the seal 402 has the function of a labyrinth seal that adapts to the different width of the joint. The transverse sealing profile has a drainage groove 406 for decompression of water pressure and primary drainage (drainage), and a drainage channel 405 which, in the event of any leakage of water past the sealing profile, collects this water and guides it downward from the building envelope system.

Cover 5 is made of a thin colored sheet. A specially shaped channel-longitudinal joint 503 runs along the lid, and a similar transverse groove 504 is formed transversely to the lid. At the end of the longitudinal joint 503, a special imprint is formed in the sheet 502, which allows custom contact of the corner elements and the lid 5 in the longitudinal contact.

The inaccurately mounted start and end position of the longitudinal seal 11 is compensated by a so-called diaphragm 702. A thin membrane 603, 703 is integrated on the corner element, which adapts to the sealing surface of the transverse joint sealing maze 402 when inserting the joint.

It is to be understood that the described solution can also be implemented in a different design that does not alter the essence of the invention.
