[0062] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0064] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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 components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0065] The inventors found that in the existing building roof structure, the metal roof used is mainly composed of metal roof panels and supporting structures. The common roof panels are connected by mechanical interlocking, and the panels and the structural layer are supported by aluminum alloy fixing seats. The entire slope roof is composed of several single panels and placed on the purlins of the roof. However, in actual application, due to the irregular shape of the roof of the special-shaped building, it is easy to cause poor drainage. Water often leaks from the metal roof into the interior of the building, which cannot meet the construction requirements of the appearance of the irregular special-shaped building.

[0066] Based on this, an embodiment of the present invention provides a building roof structure, which is described in detail below through specific embodiments.

[0067] An embodiment of the present invention provides a building roof structure, referring to Figure 1-5 As shown, it includes a metal roof 1 and a drainage system 2;

[0068] The metal roof 1 is in a slope shape with a high middle and low periphery;

[0069] The drainage system 2 includes an outer drainage ditch 21 and an inner drainage ditch 22 in a closed ring shape;

[0070] The metal roof 1 comprises a shaped structure 11 and a functional layer 12, a lining purlin 13, a waterproof layer 14, a roofing panel 15 and an aluminum plate 110 which are sequentially arranged on the shaped structure 11 from bottom to top;

[0071] The outer drainage ditch 21 is arranged near the edge of the metal roof 1, and the inner drainage ditch 22 is arranged near the middle height of the metal roof 1;

[0072] The bottom surface of the outer drainage ditch 21 and the bottom surface of the inner drainage ditch 22 are fixed to the shaping structure 11;

[0073] The tops of the outer drainage ditch 21 and the inner drainage ditch 22 are respectively flush with the roof panel 15 and sealedly connected, so that the water overflowing from the inner drainage ditch 22 can be discharged into the outer drainage ditch 21 through the roof panel 15;

[0074] The aluminum plate 110 is provided with seepage holes 1101 at the position directly above the outer drainage ditch 21 and the inner drainage ditch 22 to filter the rainwater to be collected;

[0075] A first flow guide member 27 is disposed inside the outer drainage ditch 21, and a second flow guide member 28 is disposed inside the inner drainage ditch 22;

[0076] The first drainage member 27 and the second drainage member 28 are respectively fixed to the sides of the roof panel 15, and the top surfaces of the first drainage member 27 and the second drainage member 28 are flush with the upper surface of the roof panel 15, so that rainwater on the surface of the roof panel 15 can be quickly introduced into the outer drainage ditch 21 and the inner drainage ditch 22.

[0077] In the embodiment of the present invention, referring to Figure 1-Figure 3As shown, the outer drainage ditch 21 is close to the outer edge of the metal roof 1, and the outer drainage ditch 21 is arranged close to the edge of the metal roof 1, and the inner drainage ditch 22 is arranged close to the middle height of the metal roof 1. When the rainfall is too heavy, the rainwater that cannot be discharged from the outer drainage ditch 21 in time can be discharged outside the building roof through the eaves 102. The distance between the inner drainage ditch 22 and the outer drainage ditch 21 can be reasonably set according to the size and shape of the metal roof 1. For example, the inner drainage ditch 22 can be set at 1 / 2 of the height of the roof, so that the rainwater in the area surrounded by the inner drainage ditch 22 can be discharged through the inner drainage ditch 22 as much as possible, and the rainwater in the area between the inner drainage ditch 22 and the outer drainage ditch 21 can be discharged through the outer drainage ditch 21 as much as possible, thereby realizing zoned drainage, improving drainage efficiency, and effectively preventing leakage caused by rainwater accumulation.

[0078] The building roof structure provided in the embodiment of the present invention realizes regional drainage by arranging two circles of annular drainage ditches on the sloped metal roof 1, and the tops of the outer drainage ditch 21 and the inner drainage ditch 22 are respectively flush with the roof panel 15. When the inner drainage ditch 22 is full, the excess water can flow through the roof panel 15 and then be discharged through the longer outer drainage ditch 21. Since the outer drainage ditch 21 is close to the outer edge of the roof, when the outer drainage ditch 21 is full, the water can quickly be naturally discharged from the roof through the outer edge of the metal roof 1, thereby reducing the accumulation of water and ensuring that a large amount of water on the roof can be discharged from the drainage ditch, effectively avoiding leakage.

[0079] The building roof structure provided by the embodiment of the present invention prevents large pieces of garbage such as leaves from clogging the inner and outer drainage ditches 22, 21 by arranging seepage holes 1101 at the positions of the aluminum plate 110 directly above the outer drainage ditch 21 and the inner drainage ditch 22, thereby further ensuring smooth drainage of the inner and outer drainage ditches 22, 21 and enhancing the anti-seepage effect.

[0080] In the building roof structure provided by the embodiment of the present invention, the first drainage member 27 and the second drainage member 28 are respectively fixed to the side of the roof panel 15, and the top surface of the first drainage member 27 and the second drainage member 28 is flush with the upper surface of the roof panel 15, so that rainwater on the surface of the roof panel 15 can be quickly introduced into the outer drainage ditch 21 and the inner drainage ditch 22. Figure 2 and Figure 3As shown, a first drainage member 27 is arranged inside the outer drainage ditch 21, and the longitudinal section of the first drainage member 27 is a right-angled trapezoid, and the short sides of the two parallel sides of the right-angled trapezoid are close to the inner side of the outer drainage ditch 21. The first drainage member 27 is flush with the roof panel 15 so that rainwater can quickly flow into the outer drainage ditch 21 along the first drainage member 27; a second drainage member 28 is arranged inside the inner drainage ditch 22, and the longitudinal section of the second drainage member 28 is a right-angled trapezoid, and the short sides of the two parallel sides of the right-angled trapezoid are close to the inner side of the inner drainage ditch 22. The second drainage member 28 is flush with the roof panel 15 so that rainwater can quickly flow into the inner drainage ditch 22 along the second drainage member 28, thereby improving drainage efficiency. Further, the first drainage member 27 can be arranged on both sides of the outer drainage ditch 21, and the second drainage member 28 can be arranged on both sides of the inner drainage ditch 22.

[0081] As the building roof ages or encounters collision with external objects, the roof panel 15 may be damaged. In the embodiment of the present invention, by laying the waterproof layer 14 above the purlin 13, the damage of the functional layer 12 and the parts below the functional layer 12 caused by the seepage of the roof panel 15 is effectively avoided, thereby extending the service life of the building roof.

[0082] Further, see Figure 2-Figure 5 As shown, the lining purlin 13 is a "J-shaped" lining purlin 13, and the waterproof layer 14 is laid close to the lining purlin 13, so that a drainage channel is naturally formed in the depression between the two lining purlins 13, and rainwater that leaks into the waterproof layer 14 can be discharged from the building roof through the depression between the lining purlins 13.

[0083] In the embodiment of the present invention, refer to Figure 2 and Figure 3 As shown, a plurality of first floor drains 23 are arranged in the outer drainage ditch 21, and the plurality of first floor drains 23 are arranged in sequence along the length direction of the outer drainage ditch 21; a plurality of second floor drains 24 are arranged in sequence along the length direction of the inner drainage ditch 22. The drainage system 2 also includes a plurality of first drainage pipes 25 and a plurality of second drainage pipes 26, wherein each first drainage pipe 25 is connected to a corresponding first floor drain 23; and each second drainage pipe 26 is connected to a corresponding second floor drain 24. The first drainage pipe 25 and the second drainage pipe 26 are both connected to the drainage pipe system in the building under the roof structure of the building. After rainwater is discharged from the metal roof 1 into the outer drainage ditch 21 and the inner drainage ditch 22, it is discharged from the first floor drain 23 into the first drainage pipe 25, and from the second floor drain 24 into the second drainage pipe 26, and finally discharged into the drainage pipe system in the building. The floor drain can filter larger garbage, thereby avoiding clogging the first drainage pipe 25, the second drainage pipe 26 and the drainage pipe system in the building.

[0084] In the embodiment of the present invention, refer to Figure 1-Figure 5As shown, the building roof structure also includes a main steel structure 3, which is fixed above the building body and used to support the metal roof 1. The shaping structure 11 includes a plurality of main purlins 111, a plurality of secondary purlins 112 and a plurality of first adapters 113, wherein the plurality of main purlins 111 are fixed to the main steel structure 3, the plurality of main purlins 111 and the plurality of secondary purlins 112 are correspondingly connected through the first adapters 113, and the main purlins 111 and the secondary purlins 112 are staggered to achieve shaping.

[0085] In an alternative embodiment, referring to Figure 2 and Figure 3 As shown, the inner drainage ditch 22 and the outer drainage ditch 21 are made of U-shaped steel with a preset width, and the bottoms of the inner drainage ditch 22 and the outer drainage ditch 21 are fixed above the main purlin 111.

[0086] In an alternative embodiment, referring to Figure 3-Figure 5 As shown, the functional layer 12 includes a corrugated steel sheet 121, a vapor barrier film 122 and thermal insulation rock wool 123 arranged in sequence from bottom to top. Among them, the corrugated steel sheet 121 is an aluminum-zinc perforated corrugated steel sheet 121, which can be fixed on the secondary purlin 112, so as to facilitate the subsequent laying of the vapor barrier film 122 and the thermal insulation rock wool 123. The vapor barrier film 122 can prevent water vapor from penetrating from the room into the metal roof 1, thereby effectively preventing moisture from condensing inside the metal roof 1 to form water droplets, thereby ensuring the dryness of the metal roof 1, preventing the metal roof 1 from rusting and corrosion due to excessive humidity, maintaining the integrity and appearance of the roof, and extending its service life; in addition, by preventing water vapor from entering the thermal insulation rock wool 123 through the vapor barrier film 122, the decrease in thermal resistance and the occurrence of condensation after the moisture content of the thermal insulation rock wool 123 increases can be avoided, thereby protecting the performance of the thermal insulation rock wool 123 from being damaged.

[0087] In an alternative embodiment, referring to Figure 4 and Figure 5 As shown, the lining purlin 13 passes through the functional layer 12 and abuts against the secondary purlin 112, and the bottom of the lining purlin 13 is fixed to the secondary purlin 112 by bolts, thereby fixing the functional layer 12 to the shaped structure 11. The metal roof 1 also includes a bracket 16, the lower end of the bracket 16 passes through the waterproof layer 14 and is fixed to the top surface of the lining purlin 13, and the upper end of the bracket 16 is connected to the roof panel 15, thereby supporting the roof panel 15.

[0088] In an alternative embodiment, referring to Figure 4 and Figure 5As shown, the metal roof 1 also includes a plurality of clamps 17, a plurality of second adapters 18 and an aluminum alloy profile 19. After the plate ribs at the edges of two adjacent roof panels 15 are buckled, the buckling parts of the two roof panels 15 are clamped by the clamps 17 to ensure the tight connection between the roof panels 15, so that the roof panels 15 have a waterproof effect and rainwater will not leak from the gaps between the roof panels 15. Each clamp 17 is connected to a corresponding second adapter 18, and the second adapter 18 is fixed above the clamp 17, and the upper part of each second adapter 18 is connected to the aluminum alloy profile 19. The second adapter 18 can be an angle aluminum adapter. The aluminum alloy profile 19 is used to support the aluminum plate 110, and its upper part is fixedly connected to the aluminum plate 110. The aluminum alloy profile 19 and the aluminum plate 110 can be fixedly connected by an angle code.

[0089] In an alternative embodiment, referring to Figure 4 and Figure 5 As shown, the metal roof 1 also includes a lightning protection copper wire 103, which is respectively connected to the second adapter 18 and the aluminum plate 110. Although the metal roof 1 itself has a certain conductivity, it may still be damaged by lightning in a lightning environment if there are no effective lightning protection measures. The lightning protection copper wire 103 can significantly reduce the risk of the metal roof 1 being struck by lightning, thereby protecting the integrity and safety of the roof.

[0090] In an alternative embodiment, referring to Figure 4 and Figure 5 As shown, the building roof structure also includes a plurality of adapter components 4. The adapter components 4 are respectively connected to the main steel structure 3 and the main purlin 111, so as to fix the main purlin 111 to the main steel structure 3. Specifically, the adapter component 4 includes an adapter support 41 and an adapter body 42, the adapter support 41 is fixed to the main steel structure 3, the lower end of the adapter body 42 is welded to the adapter support 41, the main purlin 111 is arranged between two corresponding adapter bodies 42, and the main purlin 111 is detachably connected by bolts passing through the main purlin 111 and the two corresponding adapter bodies 42, thereby realizing the fixed connection between the metal roof 1 and the main steel structure 3.

[0091] In a specific embodiment, the first adapter 113 is a channel steel adapter. The bottom of the first adapter 113 is welded to the main purlin 111, a secondary purlin 112 is sandwiched between the two first adapters 113, and bolts are passed through the secondary purlin 112 and the first adapters 113 on both sides of the secondary purlin 112 in sequence, so that the secondary purlin 112 can be fixed above the main purlin 111, thereby realizing a detachable connection of the secondary purlin 112.

[0092] In a specific embodiment, the roof panel 15 is made of aluminum-magnesium-manganese alloy plate. The anti-corrosion ability of the aluminum-magnesium-manganese alloy plate is not less than 20 years in a normal environment, and its surface coating increases the resistance to acid rain and industrial corrosion. At the same time, it does not react to ultraviolet rays, resists microorganisms, and does not age, thereby extending the service life of the metal roof 1; in addition, the aluminum-magnesium-manganese alloy plate has low density, light weight, high strength, and good rigidity, so it is easy to install and is suitable for various structures that require bearing capacity.

[0093] In a specific embodiment, referring to Figure 1 and Figure 2 As shown, the metal roof 1 may include a metal roof body 101 and an eave 102 located at the edge, and an external drainage ditch 21 may be provided between the metal roof body 101 and the eave 102. When the amount of rainwater is large, the water overflowing from the external drainage ditch 21 may be directly discharged through the eave 102. Furthermore, since there is no building below the eave 102, the eave 102 portion does not need to be provided with a functional layer 12 having functions such as heat preservation and moisture-proofing. For the aesthetics of the bottom of the eave 102, the aluminum plate 110 extends to the lower part of the eave 102 to wrap the eave 102.
