Description

Technical Field

[0001] This utility model relates to the technical field of metal roofing cladding systems, specifically to a mortise and tenon joint metal roofing panel and its connection nodes. Background Technology

[0002] Metal roofing systems are the main form of enclosure system for the roofs of large steel structure industrial buildings and public buildings. Traditional metal roof panels mainly function as wind and water resistance. Their structure mainly consists of two roof panels connected by rolled edges at the top and fixed to the supports.

[0003] The connection structure on the upper part of the 360° rolled edge ribs of traditional metal roof panels has poor stress performance, the strength of the roof panel is weak, and the connection method with the support is not fully integrated, with only simple point-line connection. Furthermore, it is very easy to damage the waterproofing and surface coating of the roof, resulting in significant safety and quality risks to the roof.

[0004] With the increasing demands on rooftop architecture and the application of rooftop distributed photovoltaics, the number of additional roofing elements such as decorative panels and photovoltaic modules on metal roofs is constantly growing, placing new requirements on the strength of the metal roof panels and the load-bearing capacity of the connection nodes. Based on this, the applicant has researched a mortise and tenon joint metal roof panel and its connection nodes to overcome the aforementioned deficiencies in the prior art. Summary of the Invention

[0005] To address the aforementioned issues, this utility model provides a mortise and tenon joint metal roof panel and its connecting nodes, enabling non-eccentric force distribution and mortise and tenon joint connection between the upper additional layer structure and the roof panel rib connectors. This increases the pull-out resistance of the connectors from 1-2KN in traditional roofs to 10-12KN, significantly improving the wind resistance safety of the roof additional layer and the metal roof.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A metal roof panel with mortise and tenon joints includes a male rib, a female rib, and a bottom plate; the male rib and female rib are respectively located on both sides of the bottom plate; the male rib and female rib are respectively provided with a convex rib and a rib mortise; the convex rib protrudes laterally towards the center of the bottom plate and forms a convex rib groove in the opposite direction; the convex rib includes a convex rib upper plate, a convex rib lower plate, and a convex rib end plate, and the bottom plate is provided with a raised stiffener.

[0007] The distance between the upper and lower plates of the convex rib is 3-10mm.

[0008] The rib groove shape is a horizontal rectangular groove, a horizontal U-shaped groove, an oblique rectangular groove with the rib end plate sunken, or an arc-shaped groove with the rib end plate sunken.

[0009] The male or female rib is connected to the horizontal bottom plate. Above the convex rib are the upper web plate and the locking plate, and below the convex rib are the middle web plate, the support plate, and the lower web plate.

[0010] The male rib has a lower web that bends obliquely upwards and outwards from one side of the bottom plate. The male rib support plate is formed by the lower web of the male rib bending horizontally outwards. The middle web of the male rib bends vertically upwards outside the support plate. The convex rib protrudes laterally towards the center of the bottom plate between the middle web and the upper web of the male rib. The male rib locking plate bends inwards from the top of the upper web of the male rib.

[0011] The lower web of the mother plate rib is bent obliquely upward and outward on the other side of the bottom plate. The mother plate rib support plate is bent horizontally outward from the lower web of the mother plate rib. The middle web of the mother plate rib is bent vertically upward from the outside of the support plate. The convex rib is a transverse convexity from the middle web of the mother plate rib and the upper web of the mother plate rib towards the center of the bottom plate. The mother plate rib locking edge plate is bent outward and then downward from the top of the upper web of the mother plate rib.

[0012] The stiffening mentioned above can be longitudinal stiffening or transverse stiffening. Longitudinal stiffening consists of multiple stiffening strips protruding from the upper part of the base plate and parallel to the plate ribs, while transverse stiffening consists of multiple stiffening strips protruding from the upper part of the base plate and perpendicular to the plate ribs.

[0013] The stiffening strip has a cross-section that is circular, triangular, rectangular, or trapezoidal.

[0014] The aforementioned rib mortise is composed of a lower rib plate, a middle web plate, and a support plate.

[0015] A mortise and tenon joint for metal roof panels includes a support and two adjacent roof panels. One side of the support is a male rib of one roof panel, and the other side is a female rib of the other roof panel. The support has outward-facing lateral mortises on both sides. The protruding grooves of the male and female ribs are opposite each other, and the rib mortises are inserted into the lateral mortises of the support. The male and female ribs are fitted with locking plates and connected by rolled edges.

[0016] The support also includes a rolled edge piece with a raised lateral mortise, and the rolled edge piece is sandwiched between the male plate rib and the female plate rib locking plate. The three are fitted together and connected by rolled edges.

[0017] The aforementioned joint is welded together.

[0018] The lateral mortise includes an upper mortise plate and a lower mortise plate, wherein the upper mortise plate is a flat plate or an arc-shaped plate.

[0019] The support includes a tenon-and-mortise sliding plate connected to the roof panel and a base connected to the roof purlin, wherein the sliding plate and the base are an integral structure.

[0020] The support includes a tenon-and-mortise sliding plate connected to the roof panel and a base connected to the roof purlin. The sliding plate and the base are separate structures and are slidably connected.

[0021] Compared with the prior art, the present invention has the following beneficial effects: The symmetrical ribs on the roof panel of this utility model enable non-eccentric force distribution and mortise and tenon connection between the upper additional layer structure and the roof panel rib connector, thereby increasing the pull-out resistance of the connector from 1~2KN in traditional roofs to 10~12KN, which greatly improves the wind resistance safety of the roof additional layer and metal roof.

[0022] Meanwhile, the roof panel can realize various connection methods for the roof panel and roof panel support, such as continuous welding of double stainless steel roof panels, edge rolling connection, and tenon and mortise connection. This not only improves the waterproof performance of the roof panel, but also increases the wind resistance of the traditional roof panel from 4~5 kPa to 10~12 kPa.

[0023] By adopting the technology of fixed tenon and mortise supports and sliding grooves for the ribs, the technology has been solved. The traditional metal roof panel support sliding dimension is only 30-50mm, which causes the length of a single slope of metal roof panels to generally not exceed 50 meters. This technology realizes an infinitely positionable and retractable roof panel and support groove sliding connection technology, which can achieve the technical requirement of roof panels with a single slope length of more than 100 meters without breaking the panels.

[0025] Please refer to the accompanying drawings in the specification for a further detailed explanation of this utility model.

[0026] See Figure 1 and Figure 2 A mortise and tenon joint metal roof panel includes a male rib 1, a female rib 2, and a base plate 3. The base plate 3 is the main body of the metal roof panel, and the male rib 1 and female rib 2 are the connecting and fixing parts, located on both sides of the base plate 3. Therefore, each metal roof panel has a male rib 1 and a female rib 2, and adjacent metal roof panels are assembled by splicing together the respective male rib 1 and female rib 2 on the two panels.

[0027] Male rib 1 and female rib 2 are roughly similar in shape, and are combined Figures 8-13 It has a convex rib 4 and a plate rib mortise 6. The convex rib 4 protrudes laterally towards the center of the bottom plate 3, so at the opposite direction of the convex rib 4, an outward-facing convex rib groove 5 is formed.

[0028] The base plate 3 is the main body of the metal roof. The entire metal roof panel can be integrally formed by mechanical roll forming of metal sheets of the same thickness, such as steel, aluminum alloy, stainless steel, and copper. To improve the strength of the base plate 3, it is equipped with raised transverse or longitudinal stiffeners. These transverse or longitudinal stiffeners are stiffening strips protruding from the upper part of the base plate 3, which can be perpendicular to the male rib 1 and female rib 2, or parallel to them. The stiffening strips can also have various shapes and structures, such as... Figure 1 and Figure 2The triangular stiffener 31 shown in Example 1, with a triangular cross-section, can also... Figure 3 and Figure 4 The circular stiffener 32 shown in Example 2 has a circular arc cross-section, and can also be... Figure 5 and Figure 6 The trapezoidal stiffener 33 shown has a trapezoidal cross-section. The above refers to it being parallel to male rib 1 and female rib 2; it can also be perpendicular to male rib 1 and female rib 2, for example... Figure 7 The cross-section shown is a rectangular stiffener 34. The shape and position of the stiffener can be freely combined in different ways.

[0029] The rib 4 includes an upper rib plate 41, a lower rib plate 42, and a rib end plate 43 connecting the two. The spacing between the upper rib plate 41 and the lower rib plate 42 can be determined according to actual design requirements, generally 3-10mm is appropriate. The shape of the three plates—upper rib plate 41, lower rib plate 42, and rib end plate 43—determines the shape of the rib groove 5 formed at the reverse side of the rib 4. If the upper rib plate 41 and lower rib plate 42 are horizontal flat plates and the rib end plate 43 is a vertical flat plate, a horizontal rectangular groove can be formed. If the upper rib plate 41 and lower rib plate 42 are horizontal flat plates and the rib end plate 43 is an arc-shaped plate, a horizontal U-shaped groove can be formed. Figure 8 and Figure 11 As shown. If the upper plate 41 and lower plate 42 of the convex rib are inclined downward flat plates, then an inclined rectangular groove can be formed by the downward recess of the end plate 43 of the convex rib, such as... Figure 9 and Figure 12 As shown. For example, the upper plate 41 and lower plate 42 of the convex rib are arc-shaped plates, which can form an arc-shaped groove in the recessed end plate 43 of the convex rib, such as... Figure 10 and Figure 13 As shown.

[0030] like Figure 8 , Figure 9 , Figure 10 The male rib 1 shown also includes a male rib locking plate 11, a male rib upper web plate 12, a male rib middle web plate 13, a male rib support plate 14, and a male rib lower web plate 15. The male rib lower web plate 15 is formed by bending obliquely upward and outward from one side of the base plate. The male rib support plate 14 is bent horizontally outward from the male rib lower web plate 15. The male rib middle web plate 13 is bent vertically upward outside the male rib support plate 14. The protruding rib 4 is a transverse rib protruding towards the center of the base plate between the male rib middle web plate 13 and the male rib upper web plate 12. The male rib locking plate 11 is bent inward from the top of the male rib upper web plate 12.

[0031] like Figure 11 , 12The mother plate rib 2 shown in Figure 13 also includes a mother plate rib locking plate 21, a mother plate rib upper web plate 22, a mother plate rib middle web plate 23, a mother plate rib support plate 24, and a mother plate rib lower web plate 25. The mother plate rib lower web plate 25 is bent obliquely upward and outward on the other side of the base plate 3. The mother plate rib support plate 24 is bent horizontally outward from the mother plate rib lower web plate 22. The mother plate rib middle web plate 23 is bent vertically upward from the outside of the mother plate rib support plate 24. The protruding rib 4 is a transverse protrusion towards the center of the base plate between the mother plate rib middle web plate 23 and the mother plate rib upper web plate 22. The mother plate rib locking plate 21 is bent outward and then downward from the top of the mother plate rib upper web plate 22.

[0032] On male rib 1, the lower plate 42 of the convex rib, the middle web plate 13 of the male rib, and the support plate 14 of the male rib form the rib mortise 6. On female rib 2, the lower plate 42 of the convex rib, the middle web plate 23 of the female rib, and the support plate 24 of the female rib form the rib mortise 6. The rib mortise 6 is the part used for tenon and mortise joint with the support during connection.

One side of the support 7 is the male rib 1 of one roof panel, and the other side is the female rib 2 of the other roof panel. On the body of the support 7, there are lateral mortises on both sides facing the male rib 1 and the female rib 2, namely the right mortise 72 and the left mortise 71. The protruding rib grooves 5 of the male rib 1 and the female rib 2 face each other, towards the support 7. At this time, the rib mortise head 6 is inserted into the lateral mortise of the support 7. Specifically, the rib mortise head 6 of the male rib 1 is inserted into the right mortise 72, and the rib mortise head 6 of the female rib 2 is inserted into the left mortise 71. The upper web plate 12 of the male rib and the upper web plate 22 of the female rib are fitted together, and the locking plate 21 of the female rib and the locking plate 11 of the male rib are fitted together, forming a rolled edge connection. At the joint between the web 12 of the male rib and the web 22 of the female rib, a welded connection can be selectively added to form a weld 8.

[0034] To increase the connection strength of the support 7, a rolled edge piece 73 is also provided on the support 7 body. The height of the rolled edge piece 73 exceeds the height of the lateral mortise and fits against the male rib upper web plate 12, the male rib locking plate 11, the female rib upper web plate 22, and the female rib locking plate 21. The rolled edge piece 73 is sandwiched in the middle, and the three fit together, forming a rolled edge connection. At the joint of the male rib upper web plate 12, the rolled edge piece 73, and the female rib upper web plate 22, a welded connection can be selectively added to form a weld 8.

[0035] Additionally, the lateral grooves on support 7, the right mortise 72, and the left mortise 71 all include an upper mortise plate and a lower mortise plate. The upper mortise plate can... Figure 16 and Figure 17 The flat plate shown can be used as a horizontal rectangular groove or a horizontal U-shaped groove for the corresponding roof panel rib groove 5. Alternatively, it can be as shown... Figure 18 The curved plate shown can be replaced with a curved groove for the corresponding roof panel rib groove 5.

[0036] The structure of support 7 can also adopt various different styles, such as Figure 14 The integrated structure shown can also be Figure 15 The structure shown is a split type. The support 7 mainly includes a tenon and mortise sliding piece 74 and a base 75.
