[0021] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0022] In this embodiment, if Figure 1 and Figure 2 As shown, the metal roof structure includes a plurality of sub-grid structures 1, a plurality of roof panels 2, a support assembly 3 and a gutter assembly 4. The plurality of sub-grid structures 1 are arranged in sequence at intervals, and a roof panel 2 is arranged above each sub-grid structure 1, and a gap is formed between two adjacent sub-grid structures 1. The support assembly 3 is arranged in the gap, and the support assembly 3 is connected to the sub-grid structure 1 on one side of the gap. The gutter assembly 4 is arranged in the gap, and one side of the gutter assembly 4 is connected to the support assembly 3. The side of the gutter assembly 4 facing away from the support assembly 3 is arranged at intervals with the sub-grid structure 1 on the same side to form an expansion joint 5. The gutter assembly 4 has two top ends, and the two top ends are overlapped with the roof panels 2 on both sides of the gap one by one.

[0023] For example, the sub-grid structure 1 can be set to two, three or four, etc. The number of sub-grid structures 1 can be adaptively set according to the size of the building. The larger the building area, the more sub-grid structures 1 can be. The specific number of sub-grid structures 1 is not limited here. Each sub-grid structure 1 is provided with a roof panel 2. Each sub-grid structure 1 can be provided with one, two, three or four roof panels 2. When the number of roof panels 2 is multiple, the multiple roof panels 2 are interconnected. The number of roof panels 2 on each sub-grid structure 1 is not limited here. The form of the sub-grid structure 1 is a conventional prior art, and its specific structure can be adaptively adjusted according to the different buildings, and is not limited here.

[0024] In this embodiment, a support assembly 3 and a gutter assembly 4 are arranged between two adjacent sub-grid structures 1, and the gutter assembly 4 is connected to the sub-grid structure 1 on one side of the gap through the support assembly 3, and an expansion joint 5 is formed between the gutter assembly 4 and the sub-grid structure 1 on the other side of the gap. When the sub-grid structure 1 shakes, the gutter assembly 4 is only subjected to force on one side and will not be squeezed and deformed, which is beneficial to improving the service life of the gutter assembly 4. In addition, the two top ends of the gutter assembly 4 are overlapped with the roof panels 2 on both sides of the gap one by one, which can collect rainwater and facilitate drainage.

[0025] In this embodiment, if Figure 1 and Figure 3 As shown, the support assembly 3 includes a cantilever beam 31, and the cantilever beam 31 has a connecting end and a suspended end. The connecting end is connected to the sub-grid structure 1, and the gutter assembly 4 is connected to the suspended end.

[0026] For example, the cantilever beam 31 can be a square tube, which can facilitate the cantilever beam 31 to support. The cantilever beam 31 can be a galvanized square tube. Of course, the shape and material of the cantilever beam 31 can also be set to other forms, which are not limited here.

[0027] It can be understood that by configuring the support assembly 3 in the form of a cantilever beam 31 , it is convenient to connect the gutter assembly 4 to the sub-grid structure 1 .

[0028] In this embodiment, the support assembly 3 includes a plurality of cantilever beams 31 , and the plurality of cantilever beams 31 are arranged at intervals along the length direction of the gutter assembly 4 .

[0029] By providing a plurality of cantilever beams 31 connected to the gutter assembly 4, the connection strength of the gutter assembly 4 can be improved, making the connection of the gutter assembly 4 more reliable.

[0030] In this embodiment, the width of the expansion joint 5 is A, and A≥300 mm.

[0031] For example, the width of the expansion joint 5 is 300 mm, 310 mm, 320 mm, 330 mm, 340 mm, 350 mm, 360 mm, 370 mm, 380 mm, 390 mm or 400 mm, etc. Those skilled in the art can select and set the width of the expansion joint 5 according to actual needs, and no limitation is made here. If the width of the expansion joint 5 is too small, when the gutter assembly 4 shakes, it is easy to be squeezed by the sub-grid structure 1 on both sides, and deformed.

[0032] It can be understood that by setting the width A of the expansion joint 5 to be greater than or equal to 300 mm, when the sub-grid structure 1 shakes, there can be enough space in the gap to accommodate the gutter assembly 4, thereby preventing the gutter assembly 4 from being deformed due to squeezing by the sub-grid structure 1 on both sides.

[0033] In this embodiment, the cross section of the gutter assembly 4 is U-shaped.

[0034] It can be understood that by setting the cross section of the gutter component 4 to be U-shaped and forming a groove in the middle of the gutter component 4, rainwater can be easily collected, thereby facilitating the drainage of rainwater through the gutter component 4.

[0035] In this embodiment, if Figure 1 and Figure 2As shown, the gutter assembly 4 includes a gutter keel 41, thermal insulation cotton 42, a gutter plate 43 and a bottom plate 44. The gutter keel 41 is connected to the support assembly 3, and the gutter keel 41 forms a frame with a groove; the thermal insulation cotton 42 is arranged in the frame formed by the gutter keel 41; the gutter plate 43 is arranged in the gutter keel 41; and the bottom plate 44 is arranged outside the gutter keel 41.

[0036] For example, the gutter keel 41 can be welded to the support assembly 3. By welding the gutter keel 41 and the support assembly 3, the connection strength between the two can be improved, which is conducive to improving safety. The thermal insulation wool 42 can be a rock wool board, which has the characteristics of light weight, low thermal conductivity, heat absorption and non-combustibility. The gutter board 43 can be a stainless steel gutter board 43. The bottom plate 44 can be an aluminum-magnesium-manganese corrugated bottom plate 44. Of course, the thermal insulation wool 42, the gutter board 43 or the bottom plate 44 can also be set to other materials, which are not limited here.

[0037] Specifically, the gutter keel 41 forms a frame with a groove, and the shapes of the gutter plate 43 and the bottom plate 44 match the shape of the gutter keel 41, so that the gutter assembly 4 can form a groove. For example, the cross section of the gutter keel 41 is U-shaped, and the corresponding shapes of the gutter plate 43 and the bottom plate 44 are both U-shaped.

[0038] It is understandable that by connecting the gutter keel 41 to the support assembly 3, the insulation cotton 42 and the gutter plate 43 can be supported, and the insulation cotton 42 is arranged between the bottom plate 44 and the gutter plate 43, so that the insulation cotton 42 is wrapped, and the building is insulated by the insulation cotton 42 to reduce the heat dissipation in the building. The gutter keel 41 forms a frame with a groove, so that the gutter assembly 4 can be formed into a groove, so that rainwater is collected in the gutter assembly 4 and discharged.

[0039] In this embodiment, the gutter keel 41 is a U-shaped frame formed by splicing a plurality of square tubes, and the square tubes on one side of the bottom of the gutter keel 41 are welded to the support assembly 3 .

[0040] The number of square tubes constituting the gutter keel 41 and the method of splicing the square tubes are conventional prior art, and those skilled in the art can adjust them adaptively, and are not limited here.

[0041] For example, the cantilever beam 31 of the support component 3 is a square tube, and the support component 3 includes multiple cantilever beams 31. A square tube as a part of the gutter keel 41 is welded between two adjacent cantilever beams 31, so that the support component 3 and the gutter keel 41 can be reliably connected, so that the support component 3 can stably support the gutter keel 41.

[0042] It is understandable that the gutter keel 41 is formed by splicing a plurality of square tubes, which can reduce the weight of the gutter keel 41. The gutter keel 41 is spliced ​​into a U-shaped frame, so that the gutter keel 41 can form a groove, so that the gutter plate 43 can be set to a shape matching the gutter keel 41 and better support the gutter plate 43. The square tube on the bottom side of the gutter keel 41 is welded to the support assembly 3, which can improve the connection strength between the gutter keel 41 and the support assembly 3. In addition, the square tube can be easily connected and supported.

[0043] In this embodiment, if Figure 1 and Figure 3 As shown, the sub-grid structure 1 includes a main purlin 11 , and the support assembly 3 is connected to the main purlin 11 .

[0044] The specific configuration of the main purlin 11 is conventional in the prior art and is not limited here.

[0045] In this embodiment, by connecting the support assembly 3 to the main purlin 11 , the support assembly 3 can be reliably fixed, which is beneficial to improving the stability of the connection of the gutter assembly 4 .

[0046] In this embodiment, if Figure 1 As shown, the metal roof structure further includes a flashing plate 6 and a telescopic plate 7. The flashing plate 6 is arranged between the top end on the same side as the support assembly 3 and the roof panel 2; the telescopic plate 7 is arranged between the other top end and the roof panel 2 on the same side.

[0047] Specifically, the material of the flashing plate 6 can be the same as the material of the roof, which is not limited here. For example, the flashing plate 6 is connected to the top of the gutter assembly 4 by screws, and the flashing plate 6 is connected to the roof panel 2 by screws. Of course, the flashing plate 6 can also be connected to the top and the roof panel 2 by other methods, which is not limited here. The telescopic plate 7 is connected to the support assembly 3 by screws, and the telescopic plate 7 is overlapped with the roof panel 2.

[0048] It can be understood that by arranging a flashing board 6 between the top of one side of the support assembly 3 and the roof panel 2, the flashing board 6 can block rainwater to better collect rainwater in the gutter plate 43, which is beneficial to improve the waterproof effect. By arranging a telescopic plate 7 between the top of the other side of the support assembly 3 and the roof panel 2 on the same side, while waterproofing can be achieved through the telescopic plate 7, the telescopic plate 7 has a certain telescopic space, so that when the gutter assembly 4 and the roof panel 2 shake, better waterproofing can also be achieved.

[0049] In this embodiment, the telescopic plate 7 includes a plurality of bent plate segments connected in sequence.

[0050] It can be understood that the telescopic plate 7 includes a plurality of bent plate segments connected in sequence. The telescopic plate 7 can be extended when subjected to tension and can be shortened when subjected to compression, so that the telescopic plate 7 can adapt to the shaking of the supporting assembly 3 and the roof panel 2.
