Description

Technical Field

[0001] The invention relates to the technical field of wall panel construction, and in particular to a fusion plate metal roofing system. Background Art

[0002] In modern building structures, metal roofing systems are widely used in various industrial and civil buildings due to their advantages of light weight, high strength, good durability, and easy construction and maintenance. However, traditional metal roofing systems often have some shortcomings in design, especially in terms of waterproofing, heat preservation, wind resistance, and overall aesthetics of the roof.

[0003] First, in terms of waterproof performance, traditional metal roof systems usually use simple overlap or welding to connect metal roof panels. This method is prone to leakage under long-term wind and rain, affecting the normal use of the building. Secondly, in terms of thermal insulation performance, metal materials have a high thermal conductivity. If effective thermal insulation treatment is not performed, it will cause large fluctuations in indoor temperature and increase energy consumption. In addition, traditional metal roof systems are also insufficient in terms of wind resistance. Especially in strong wind areas, metal roof panels are easily blown away by the wind, causing safety hazards.

[0004] In order to solve the above problems, some improved metal roof systems have appeared on the market, but these systems often have complex structures, difficult construction, high costs and other problems, and are difficult to be widely used. Therefore, it is particularly important to develop a metal roof system with simple structure, convenient construction, good waterproof and heat insulation effect and strong wind resistance.

[0029] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] The following will be combined with the drawings in the embodiments of the invention to clearly and completely describe the technical solutions in the embodiments of the invention. Obviously, the described embodiments are only part of the embodiments of the invention, not all of the embodiments. Based on the embodiments of the invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the invention.

[0031] Example 1 like Figure 1-14 As shown: a fusion plate metal roof system, which is designed for the plane overlapping part of the metal roof panel, including multiple metal roof panels 1 overlapped with each other in the horizontal and vertical directions, the upper plate surface of the metal roof panel is covered with a TPO coil layer 2, a plurality of wave-bee-shaped protrusions 3 are installed side by side in the horizontal direction on the metal roof panel, two adjacent metal roof panels are overlapped and installed in the longitudinal direction, and two adjacent metal roof panels are installed in a mutually clamped manner in the horizontal direction. The first joint part 4 and the second joint part 5 that are clamped with each other are installed at both ends of the metal roof panel in the horizontal direction respectively, and the first joint part and the second joint part form a clamping structure, and a TPO cap 6 is provided on the metal roof panel at a position corresponding to the upper part of the clamping structure.

[0032] As a preferred embodiment, the cross section of the peak-shaped protrusion 3 is a trapezoid, which not only increases the contact area of ​​the protrusion and improves the bonding force with the upper and lower layers of materials, but also enables the protrusion to better disperse stress when subjected to external force, avoiding damage caused by stress concentration. Therefore, the trapezoidal peak-shaped protrusion significantly enhances the structural stability of the metal roof panel, making it more resistant to external loads such as wind pressure and snow pressure.

[0033] As a preferred embodiment, the metal roof panel 1 is a composite panel body, which includes a first metal layer 101 and a second metal layer 102, and a filling material layer 103 is installed between the first metal layer and the second metal layer; this design combines the strength of the metal material with the heat preservation and sound insulation properties of the filling material, so that the metal roof panel has good heat preservation, sound insulation and fireproof properties while maintaining high strength. This greatly improves the overall performance of the roof and meets the needs of modern buildings for multifunctionality.

[0034] As a preferred embodiment, reinforcing ribs 104 are installed side by side on the first metal layer 101 and the second metal layer 102, and the reinforcing ribs are arranged in the longitudinal direction; this design significantly enhances the strength of the metal roof panel in the longitudinal direction, making it more resistant to longitudinal loads and deformation. At the same time, the reinforcing ribs also play a role in dispersing stress, avoiding damage caused by excessive local stress. Therefore, the addition of reinforcing ribs further improves the structural stability and durability of the metal roof panel.

[0035] As a preferred embodiment, the first joint part 4 includes an insertion protrusion 105 installed at one end of the metal roof panel, and the second joint part 5 includes an insertion groove 106 and a positioning bending plate 107 installed on the other end of the metal roof panel. The positioning bending part overlaps the wave bee-shaped protrusion on the adjacent metal roof panel, and the insertion groove and the insertion protrusion are engaged with each other; this design ensures that the metal roof panel can be tightly connected in the lateral direction and is not easy to loosen; the positioning bending plate overlaps the wave bee-shaped protrusion on the adjacent metal roof panel, which not only increases the contact area of ​​the connection, but also further enhances the stability of the connection by physical interlocking; the bending protrusion installed at the end of the positioning bending plate cooperates with the positioning groove on the metal roof panel to form an additional locking mechanism, which effectively prevents the relative displacement of the roof panel when subjected to external force.

[0036] As a preferred embodiment, a bending protrusion 108 is installed at the end of the positioning bending plate 107, and a positioning groove 109 is designed on the wave-beam-shaped protrusion at one end of the metal roof panel away from the positioning bending part. Specifically, the positioning groove 109 is designed on the side of the wave-beam-shaped protrusion away from the edge, and the positioning groove and the bending protrusion cooperate with each other; the snap-fit ​​structure of the insertion protrusion and the insertion groove, and the overlap of the positioning bending plate and the wave-peak-shaped protrusion, together constitute a tight waterproof barrier, which effectively prevents moisture from penetrating from the overlap gap; the cooperation between the positioning groove and the bending protrusion further enhances the waterproof effect, and ensures that the waterproof performance of the roof is not affected even under extreme weather conditions.

[0037] As a preferred embodiment, the insertion protrusion 105 and the insertion groove 106 are formed by bending the second metal layer 102, and the positioning groove 109 and the positioning bending plate 107 are formed by bending the first metal layer 101; the insertion protrusion, the insertion groove, the positioning bending plate and other components are all formed by bending the metal layer. This standardized design makes the installation and disassembly during the construction process easier and faster. Construction workers can more easily achieve accurate alignment and fixation of the roof panels, reduce installation errors, and improve construction efficiency and quality.

[0038] In addition, the above design reduces the wear and aging of the overlap by optimizing the connection structure, thereby extending the service life of the metal roof panel; the installation of the positioning bending plate and the bending protrusion also increases the strength of the connection part, making the entire roof system more durable; the design of the plug-in protrusion, the plug-in groove, the positioning bending plate and other components not only enhances the stability of the connection, but also makes the roof visually neater and more beautiful; the combination of the wave-bee shaped protrusion and the positioning bending plate also helps drainage and ventilation, improving the functionality of the roof.

[0039] As a preferred embodiment, an inverted U-shaped nailing piece 7 is installed on the snap-fit ​​structure, and the nailing piece fixes two adjacent metal roof panels through a fixing nail 8. The inner wall of the TPO cap 6 is bonded to the top of the nailing piece through a self-adhesive piece 9, and the two sides of the TPO cap extend and overlap the TPO coil layer on the metal roof panel; the TPO coil layer 2 on the metal roof panel is installed with an extension 10 in the longitudinal direction, and the extension extends downward and overlaps the TPO coil layer 2 of the adjacent metal roof panel. The above structural design has the following advantages: (1) Enhanced fixing stability: By installing an inverted U-shaped nailing piece on the snap-fit ​​structure and fixing two adjacent metal roof panels with fixing nails, this design ensures a more secure connection between the roof panels. The nailing piece not only provides additional support, but also achieves a deeper level of fixation by penetrating the roof panel and the TPO coil layer, effectively preventing the roof panel from loosening or shifting when subjected to external forces. (2) Optimized waterproof sealing: The inner wall of the TPO cap is bonded to the top of the nailing piece by a self-adhesive piece. This design not only simplifies the installation process, but also ensures a tight fit between the cap and the nailing piece. At the same time, the two sides of the TPO cap extend and overlap the TPO membrane layer on the metal roof panel, forming a continuous waterproof barrier, which effectively prevents moisture from penetrating from the overlap gap. The extension of the TPO membrane layer on the metal roof panel installed in the longitudinal direction further enhances the waterproof effect. The extension extends downward and overlaps the TPO membrane layer of the adjacent metal roof panel to form an overlapping waterproof layer, which ensures that the waterproof performance of the roof is not affected even in extreme weather conditions. (3) Improved construction efficiency and precision: The installation of the inverted U-shaped nailing piece and self-adhesive piece makes the fixing and sealing during the construction process easier and faster. Construction workers can more easily achieve precise alignment and fixing of the roof panel, reducing installation errors and improving construction efficiency and quality. (4) Enhanced structural durability and service life: By optimizing the connection structure and waterproof design, the wear and aging of the overlap is reduced, thereby extending the service life of the metal roof panel and TPO membrane layer. At the same time, the sturdy design of the nailing parts and TPO caps also increases the durability of the entire roof system. (5) Improved aesthetics and functionality: The design of the TPO cap not only enhances the waterproof performance, but also makes the roof visually neater and more beautiful. At the same time, the extended part of the cap fits tightly with the TPO membrane layer, which also avoids visual defects caused by exposed fixings; the installation of the extension not only enhances the waterproof effect, but also helps drainage and ventilation, improving the functionality of the roof.

[0040] Regarding the design of the ridge position in the roof system, the metal roof panels 1 are distributed along both sides of the ridge, and a sealing filling structure 12 is installed between the metal roof panels on both sides at the corresponding ridge position, and an integrated ridge cover plate 11 is provided on the steel beam at the position directly above the sealing filling structure; wherein the integrated ridge cover plate 11 includes a ridge cover plate body 201, the ridge cover plate body is arched, and the ridge cover plate body is provided with wave-shaped protrusions 202 installed at intervals along the length direction of the ridge, and the ridge cover plate body is provided with downwardly bent overlapped parts 203, and the top of the ridge cover plate body is covered with a TPO layer 204; wherein, in the preferred design scheme, the cross section of the wave-shaped protrusion 202 is a trapezoid. The beneficial effects of the integrated ridge cover plate of this design are mainly reflected in the following aspects: (1) Enhanced structural strength and stability: The ridge cover plate body is arched, and this shape itself can provide better structural strength and stability, and can resist pressure from above, such as snow accumulation, wind pressure, etc. The addition of the wave-shaped protrusions further enhances the structural strength of the ridge cover. In particular, when the cross-section of the wave-shaped protrusions is designed to be trapezoidal, this shape not only provides a larger contact area and increases the firmness of the connection with the ridge cover body, but also can more effectively disperse and resist external forces, making the entire ridge cover more stable. (2) Optimizing drainage performance: The design of the wave-shaped protrusions helps to form a natural drainage channel, allowing rainwater to quickly flow along the grooves between the protrusions, avoiding the occurrence of water accumulation. The trapezoidal cross-sectional design makes the grooves between the protrusions more spacious, which is conducive to the rapid discharge of rainwater and reduces the risk of leakage caused by water accumulation. (3) Improving sealing performance: The downwardly bent overlaps on both sides of the ridge cover body can fit tightly with the adjacent metal roof panels or wall structures to form an effective sealing barrier. The TPO layer (thermoplastic polyolefin) coating not only provides good waterproof performance, but also enhances the bonding force between the ridge cover and the metal roof panel, further improving the sealing effect. (4) Extending service life: The TPO layer has excellent weather resistance and corrosion resistance, and can resist erosion by environmental factors such as ultraviolet rays, acid and alkali, thereby extending the service life of the roof ridge cover. The design of the wave-shaped protrusion also helps to reduce dust and dirt on the surface of the roof ridge cover, making cleaning and maintenance more convenient, further extending the service life of the roof ridge cover. (5) Improving aesthetics and practicality: The design of the wave-shaped protrusion not only enhances the structural performance of the roof ridge cover, but also gives it a unique visual effect, improving the overall aesthetics of the building. At the same time, this design also takes practicality into consideration, making the roof ridge cover more convenient to install, maintain and replace. In summary, this design of the integrated ridge cover, through the comprehensive application of the arched body, wave-shaped protrusion (trapezoidal cross section), overlap and TPO layer, achieves a comprehensive improvement in structural strength, drainage performance, sealing performance, service life and aesthetics, and has high practical value and promotion significance.

[0041] The sealing filling structure 12 includes a foam rod 13 and a polyurethane foam layer 14 installed between two metal roof panels. The polyurethane foam layer 14 is filled in the gap between the metal roof panels and the foam rod.

[0042] The fusion plate metal roof ridge structure of this design, especially the preferred scheme of its sealing filling structure, brings the following significant beneficial effects: (1) Excellent sealing performance: By installing foam rods between the metal roof panels and filling the gaps with polyurethane foam layers, a solid sealing barrier is formed. This double sealing design greatly reduces the possibility of penetration of rainwater, moisture and other external factors, ensuring the long-term stability and durability of the ridge structure. (2) Enhanced structural stability: The foam rods and polyurethane foam layers not only play a sealing role, but also can absorb and disperse the pressure from the roof, such as wind force, snow pressure, etc. to a certain extent. This design enhances the overall stability of the ridge structure, enabling it to better withstand the influence of severe weather conditions. (3) Improved construction efficiency: The polyurethane foam layer has the characteristics of fast curing and easy construction, which can greatly shorten the construction period. At the same time, the combined use of foam rods and polyurethane foam layers also simplifies the installation process of the sealing filling structure, reducing the construction difficulty and cost. (4) Good thermal insulation performance: The polyurethane foam layer is a high-quality thermal insulation material, and its low thermal conductivity can effectively prevent the transfer of heat. Therefore, this sealing filling structure not only improves the sealing of the ridge structure, but also improves the thermal insulation performance of the building to a certain extent and reduces energy consumption. (5) Environmental protection and sustainability: The polyurethane foam layer is usually made of renewable or recyclable materials, which meets the requirements of environmental protection and sustainable development. At the same time, this material does not produce harmful substances during use and is harmless to the environment and human health. (6) Strong adaptability: This sealing filling structure is suitable for various types of metal roof panels and ridge structures, and has good versatility and adaptability. Whether it is a new building or an old building renovation, this design can be used to meet the sealing and stability requirements of the ridge structure.

[0043] As a preferred design scheme, a Z-shaped purlin 15 is installed on the steel beam 19 at one end below the metal roof panel and close to the ridge, and an inner ridge board 16 is installed on the Z-shaped purlin. The inner ridge board supports the metal roof panel from the bottom, and a TPO waterproofing membrane layer 17 is laid on the outer surface of the metal roof panel; a TPO waterproofing membrane layer 2 18 is also installed between the integrated ridge cover plate and the metal roof panel, and the ends of the TPO waterproofing membrane layer 2 are overlapped on the metal roof panels on both sides. Specifically, the TPO waterproofing membrane layer 1 is an L-shaped TPO waterproofing membrane, and the TPO waterproofing membrane layer 2 is an H-shaped waterproofing membrane; the laying direction of the TPO waterproofing membrane layer 1 7 is perpendicular to the ridge and is pasted on the metal roof panel along the crests and troughs, and the TPO waterproofing membrane layer 2 is laid flat on the entire ridge along the ridge direction.

[0044] These designs bring the following significant benefits: (1) Enhanced structural support and stability: The installation of Z-shaped purlins provides a solid support for the inner ridge board, thereby enhancing the bearing capacity of the metal roof panel at the ridge. This design helps to disperse and resist various loads from the roof, such as wind force, snow pressure, etc., and improves the overall stability of the ridge structure. (2) Excellent waterproof performance: The combination of L-type TPO waterproof membrane layer 1 and H-type TPO waterproof membrane layer 2 forms a complete waterproof barrier. TPO (thermoplastic polyolefin) material has excellent weather resistance, chemical corrosion resistance and waterproof performance, which can effectively prevent moisture penetration and protect the building structure from water damage. The L-type design enables the membrane to better fit the outer surface of the metal roof panel, while the H-type design ensures a tight connection between the membrane and the ridge cover plate, further improving the waterproof effect. (3) Improved construction efficiency and quality: TPO waterproof membrane is easy to cut, lay and weld, which greatly simplifies the construction process. At the same time, its excellent physical properties and chemical stability ensure the reliability and long-term stability of construction quality. The standardized design of Z-shaped purlins and ridge boards makes the installation process simpler and faster, reducing the difficulty and cost of construction. (4) Enhance the durability of the building: The combined use of TPO waterproof membrane layer one and layer two not only improves the waterproof performance of the building, but also can resist the erosion of environmental factors such as ultraviolet rays, acid and alkali to a certain extent, extending the service life of the building. The solid support of Z-shaped purlins and ridge boards also helps to reduce the risk of leakage caused by structural deformation, further enhancing the durability of the building. (5) Improve the aesthetics of the building: The smooth laying of TPO waterproof membrane layer one and layer two makes the roof appearance more neat and beautiful. At the same time, the L-shaped and H-shaped designs also give the membrane a unique visual effect, improving the overall aesthetics of the building.

The wall frame includes a longitudinal frame and a transverse frame, and there is a sealing portion between the longitudinal frame and the transverse frame. The first plate surface and the second plate surface of the composite eaves sealing plate are respectively sealed and connected to the transverse frame and the longitudinal frame.

[0046] Among them, the composite eaves sealing plate 301 includes a TPO layer 302 located on the outer layer and a metal layer 303 located on the inner layer. The composite eaves sealing plate includes a first panel surface 304 for connecting to the roof panel, and wave-shaped protrusions 305 matching the roof panel are evenly installed on the first panel surface. A second panel surface 306 is installed downward at the end of the first panel surface. The second panel surface is a multi-bending structure, and an open receiving groove 307 is formed between the inner side of the second panel surface and the first panel surface.

[0047] As a preferred design, a plurality of reinforcing ribs 308 are installed between the two corresponding wave-shaped protrusions on the first plate surface 304. The reinforcing ribs 308 are arranged in parallel with the three wave-shaped protrusions. The above design can achieve the following functions: (1) Enhance structural stability: A plurality of reinforcing ribs are installed between the two corresponding wave-shaped protrusions on the first plate surface. These reinforcing ribs are arranged in parallel with the wave-shaped protrusions, which can further enhance the structural strength of the connection between the eaves cover plate and the roof panel, and improve the overall stability and load-bearing capacity.
