[0027] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0028] Figure 1 A schematic diagram of the structure of the roof structure 1 according to an embodiment of the present application is shown. Figure 1 As shown, the roof structure 1 of the embodiment of the present application includes a plurality of steel beams 10, a plurality of purlins 20 and a panel 30. Specifically, the plurality of steel beams 10 are arranged at intervals in the first direction. The plurality of purlins 20 are arranged at intervals in the second direction and supported on the upper surfaces of the plurality of steel beams 10, the plurality of purlins 20 include a first purlin 21 and two second purlins 22, the first purlin 21 is centrally arranged between the two second purlins 22, and the first direction is perpendicular to the second direction. The panel 30 is supported on the upper surfaces of the plurality of purlins 20 and is fixedly connected to the plurality of purlins 20, respectively. Among them, the height of the upper surface of the first purlin 21 is greater than the height of the upper surface of the second purlin 22, so that the panel 30 is bent and deformed in the second direction.

[0029] In the embodiment of the present application, the first direction and the second direction may be two horizontal directions perpendicular to each other. A plurality of steel beams 10 may be arranged at intervals in the first direction, and each steel beam 10 may extend along the second direction. A plurality of purlins 20 may be arranged at intervals in the second direction, and each purlin 20 may extend along the first direction. Each purlin 20 is respectively supported and fixedly connected to the upper side surfaces of the plurality of steel beams 10.

[0030] In some examples, the upper surface of the steel beam 10 may be a horizontal plane, and the height dimensions of the first purlin 21 and the second purlin 22 may be set to be different so that the upper surface of the first purlin 21 and the upper surface of the second purlin 22 are at different heights in the vertical direction.

[0031] In other examples, the upper surface of the steel beam 10 can be inclined, and the heights of the first purlin 21 and the second purlin 22 can be the same. The height of the position of the steel beam 10 for supporting the first purlin 21 is greater than the height of the position for supporting the second purlin 22.

[0032] In the embodiment of the present application, the panel 30 may adopt an integrated structure, that is, during the assembly process of the roof structure 1, the panel 30 of the integrated structure may be directly supported and fixed to the upper side surfaces of the plurality of purlins 20 .

[0033] It should be noted that, since the height of the upper surface of the first purlin 21 is greater than the height of the upper surface of the second purlin 22, the middle area of ​​the panel 30 in the second direction is supported on the upper surface of the first purlin 21, and the two side areas located in the middle area are supported on the upper surfaces of the two second purlins 22. Such an arrangement can enable the panel 30 to bend and deform in the direction from the middle area to the two side areas, so that the panel 30 bends with a certain curvature and forms two arc-shaped slopes on both sides of the middle area of ​​the panel 30.

[0034] It can be understood that the degree of bending of the panel 30 depends on the height difference between the upper surfaces of the first purlin 21 and the second purlin 22 and the spacing between the first purlin 21 and the second purlin 22 in the second direction. Those skilled in the art can set the height difference and the spacing accordingly according to actual conditions to adjust the degree of bending of the panel 30.

[0035] Compared with the related art that requires the use of a ridge to connect two metal roofs at an angle to each other, the roof structure 1 of the embodiment of the present application only uses one panel 30 to form two slopes at an angle to each other. While simplifying the roof structure 1, the appearance consistency of the roof structure 1 is improved, and the gap caused by the splicing of the two metal roofs is eliminated, which significantly improves the waterproof performance of the roof structure 1, reduces building materials, and is conducive to reducing construction costs and labor, and is also conducive to reducing the difficulty of subsequent maintenance. In addition, the roof is integrally formed without protruding parts, and the wind-resistant performance of the roof structure 1 is even better.

[0036] In one embodiment, the bending angle of the panel 30 in the second direction is less than or equal to 10 degrees.

[0037] In the embodiment of the present application, the bending angle of the panel 30 can be understood as the central angle of the arc surface of the panel 30 that is bent and deformed. It should be noted that the portion of the panel 30 that is bent and deformed is the portion of the panel 30 located between the two second purlins 22, wherein the bending angle of the portion of the panel 30 located between the first purlin 21 and any second purlin 22 is less than or equal to 5 degrees.

[0038] In one embodiment, the height difference between the upper surface of the first purlin 21 and the upper surface of the second purlin 22 is ΔH, the distance between the first purlin 21 and the second purlin 22 in the second direction is D, and the height difference ΔH and the distance D satisfy the following relationship: D / ΔH≤0.087.

[0039] Figure 2 A front view of the roof structure 1 according to an embodiment of the present application is shown. Figure 2 As shown, the height of the upper surface of the first purlin 21 is H1, the height of the upper surface of the second purlin 22 is H2, and the height difference ΔH between the upper surface of the first purlin 21 and the upper surface of the second purlin 22 is H1-H2. The height of the upper surface of the first purlin 21 can be the distance between the upper surface of the first purlin 21 and the plane where the steel beam 10 is located. Similarly, the height of the upper surface of the second purlin 22 can be the distance between the upper surface of the second purlin 22 and the plane where the steel beam 10 is located.

[0040] Among them, the supporting point of the first purlin 21 for the panel 30 is A1, the supporting point of the second purlin 22 for the panel 30 is A2, the tangent value tanα of the angle α between the straight line passing through the supporting point A1 and the supporting point A2 and the horizontal line is D / ΔH, and tanα≤0.087, thereby, the angle α can be less than or equal to 5 degrees.

[0041] In one embodiment, the panel 30 is fixedly connected to the purlin 22 via a fastener 41 , and a cover sheet 42 covering the outside of the fastener 41 is further provided on the upper surface of the panel 30 .

[0042] Exemplarily, the fastener 41 may be a bolt, and the bolt sequentially passes through the first through hole on the panel 30 and the second through hole on the second purlin 22 and is fastened with a nut, so that a fixed connection is formed between the panel 30 and the second purlin 22. A cover sheet 42 is provided on the upper surface of the panel 30, and the cover sheet 42 covers the outer side of the fastener 41 to shield the fastener 41. Such a configuration can seal the gap between the fastener 41 and the panel 30, prevent rainwater from penetrating into the gap between the fastener 41 and the panel 30, and thus achieve a certain waterproof effect.

[0043] In one embodiment, the panel 30 includes a metal plate and a waterproof membrane layer, the waterproof membrane layer is bonded to the upper surface of the metal plate, and the material of the waterproof membrane layer includes thermoplastic polyolefin (TPO) and polyvinyl chloride (PVC).

[0044] Exemplarily, the material of the metal sheet can be steel. It is understandable that the TPO membrane layer is made of polypropylene (PP) and polyethylene (PE) through a special process and has good weather resistance, aging resistance, wear resistance and UV resistance.

[0045] Through the above implementation, the panel 30 can have excellent anti-corrosion and waterproof properties, which can significantly improve the service life of the roof structure 1.

[0046] Optionally, the thickness of the metal sheet is 0.6 to 0.8 mm, and the thickness of the waterproof membrane layer is 0.2 to 1.8 mm.

[0047] Such a configuration can make the overall thickness of the panel 30 within the range of 0.8 to 2.6 mm, which is beneficial to reducing the thickness of the panel 30, thereby reducing the weight of the panel 30, and is also beneficial to making the panel 30 bend naturally to form two slopes of the roof structure 1.

[0048] In one embodiment, the panel 30 includes a plurality of panel units adjacent to each other in sequence, each panel unit includes a metal plate and a waterproof membrane layer; wherein the metal plates of two adjacent panel units overlap each other and are connected by welding through the waterproof membrane layer.

[0049] Exemplarily, the edges of the metal plates of any two adjacent panel units overlap each other, and the waterproof membrane layers of the two panel units are stacked and welded together.

[0050] Through the above implementation, the splicing method between the multiple panel monomers can be made simpler, and the connection through the waterproof membrane layer is beneficial to improving the waterproof performance between the multiple panel monomers.

[0051] In one embodiment, the metal sheet is provided with a plurality of strip-shaped protrusions 31, which extend along the second direction and are spaced apart in the first direction; wherein the spacing between the strip-shaped protrusions 31 is 260 to 300 mm, the height of the strip-shaped protrusions 31 is 25 to 35 mm, and the width of the strip-shaped protrusions 31 is 60 to 100 mm.

[0052] Figure 3 A side view of the roof structure 1 according to an embodiment of the present application is shown. Figure 3As shown, in some examples, the cross-sectional shape of the strip-shaped protrusion 31 can be approximately trapezoidal. In the cross-sectional shape of the strip-shaped protrusion 31, two oblique edges and a straight edge connected between the two oblique edges can be included, wherein the straight edge is parallel to the plane where the metal sheet is located, one end of the two oblique edges respectively extends to the plane where the metal sheet is located, and the other ends of the two oblique edges are respectively connected to the two ends of the straight edge. The width of the strip-shaped protrusion 31 can be the maximum distance between the two oblique edges, and specifically can be 80 mm; the width of the straight edge can be 20 mm; the spacing between any two adjacent strip-shaped protrusions 31 can be 280 mm.

[0053] Exemplarily, there are a plurality of strip-shaped protrusions 31 arranged at intervals in the first direction, and there may be at least one fastener 41 for connecting the panel 30 and the second purlin 22 , which is respectively arranged between adjacent strip-shaped protrusions 31 .

[0054] In one embodiment, the purlin 20 is fixedly connected to the upper surface of the steel beam 10 via a purlin support plate 50 .

[0055] Exemplarily, the purlin support plate 50 may include a first connection portion and a second connection portion at right angles to each other, the first connection portion may be fixedly connected to the upper surface of the steel beam 10 by a fastener, and the second connection portion may be fixedly connected to the side surface of the purlin 20 by a fastener.

[0056] In the embodiment of the present application, the structures of the first purlin 21 and the second purlin 22 may be the same or different. For example, the first purlin 21 may be a rectangular tube with a rectangular cross section, and the second purlin 22 may be a C-shaped tube with a "C"-shaped cross section. In addition, the steel beam 10 may be an I-beam with an "I"-shaped cross section.

[0057] In one embodiment, the steel beam 10 includes a first beam body 11 and a second beam body 12, the ends of the first beam body 11 and the second beam body 12 are butt-jointed, and the angle between the first beam body 11 and the second beam body 12 is greater than or equal to 170 degrees and less than 180 degrees. The angle between the first beam body 11 and the second beam body 12 can be understood as the angle between the length direction of the first beam body 11 and the length direction of the second beam body 12.

[0058] In the embodiment of the present application, the first beam body 11 and the second beam body 12 can be a single body or an integrally formed part, which is not specifically limited in the embodiment of the present application.

[0059] Preferably, the angle between the first beam body 11 and the second beam body 12 is complementary to the bending angle of the panel 30. For example, the bending angle of the panel 30 may be 10 degrees, and the angle between the first beam body 11 and the second beam body 12 may be 170 degrees.
