[0011] One end of the fastening support penetrates the insulation board, and the fastening support is provided with standing seam roof panels on both sides, and the end of the fastening support penetrating the insulation board is sequentially sleeved with a second hooking part and a first hooking part from inside to outside.

[0012] By adopting the adapter and the fastening support, the stable installation of the standing seam roof panel is ensured, the connection between adjacent standing seam roof panels is realized through the connection of the first hooking part and the second hooking part at one end of the fastening support, and the stability of the system is enhanced. The first hooking part, the second hooking part and the fastening support are used for connection, there is no gap, and the waterproof performance of the roof surface is improved.

[0027] A reset member is connected between the inner side walls of the water collecting cylinder at the bottom of the cover and is used to drive the cover to slide away from the roof layer structure.

[0028] By adopting the technical scheme, when rainwater flows into the containing groove along the cover and accumulates to a certain amount, the cover moves downward under the action of the gravity of the rainwater to close the opening below the water collecting cylinder, further preventing the rainwater from directly contacting the standing seam roof panel. After the opening below the water collecting cylinder is closed, the rainwater is drained along the flow guide pipe to the drain pipe; after the water in the containing groove dries, the reset member drives the cover to return to the initial position to open the opening below the water collecting cylinder, so that air can smoothly flow along the water collecting cylinder to the surface of the standing seam roof panel.

[0029] Optionally, the cross section of the cover is tapered away from the roof layer structure, and the containing groove is circumferentially arranged along the edge of the bottom of the cover.

[0030] By adopting the technical scheme, the tapered design of the opening and closing cover and the containing groove can more effectively collect and guide rainwater, so that the containing groove is filled with rainwater as soon as possible, and the opening below the water collecting cylinder is closed in time, further reducing the amount of water falling on the surface of the standing seam roof panel.

[0071] Example 3:

[0072] With reference to Figure 4 , the difference between this embodiment and example 1 is that a drainage structure 6 is additionally arranged above the roof layer structure 2. The drainage structure 6 comprises a water collecting plate 61 and a plurality of water collecting cylinders 62, the plurality of water collecting cylinders 62 are arranged through and fixedly connected to the water collecting plate 61, are arranged at intervals on the water collecting plate 61, and are arrayed. The upper surface of the water collecting plate 61 and the inner side wall of the water collecting cylinder 62 are both covered with sound insulation pads 7, and in this embodiment, the sound insulation pads 7 are made of rubber. The cross section of the water collecting cylinder 62 is tapered towards the direction close to the roof layer structure 2, and each water collecting cylinder 62 is provided with a flow guide pipe 63, one end of the flow guide pipe 63 communicates with the water collecting cylinder 62 after penetrating through the inner side wall of the water collecting cylinder 62 and the sound insulation pad 7 in sequence.

[0073] With reference to Figure 4 , a drainage pipe 64 is arranged between each two adjacent water collecting cylinders 62, one end of the flow guide pipe 63 away from the water collecting cylinder 62 communicates with the drainage pipe 64, and the drainage pipe 64 is located below the connection position of the flow guide pipe 63 and the water collecting cylinder 62. A connecting column (8) is fixedly connected to the bottom wall of the water collecting plate 61, one end of the connecting column (8) is fixedly connected to the standing seam roof panel 24, and the drainage pipe 64 is arranged through the connecting column (8) and fixedly connected to the connecting column (8). In rainy weather, rainwater falls on the water collecting plate 61 and the water collecting cylinder 62, and most of the rainwater flows into the drainage pipe 64 along the flow guide pipe 63 and is discharged, thereby realizing effective collection and guidance of the roof rainwater. After the rainwater falls on the roof, it first contacts the sound insulation pad 7, and the sound insulation pad 7 buffers the rainwater to further reduce noise.

[0074] With reference to Figure 5Further, the water collecting cylinder 62 is further provided with a sliding opening and closing cover 65 for opening or closing the opening below the water collecting cylinder 62. The cross section of the opening and closing cover 65 is tapered towards the direction of the roof structure 2, and the edge of the bottom of the opening and closing cover 65 extends outwardly and then bends upwardly to form a containing groove 651 on the side away from the roof structure 2 for temporarily storing rainwater. Meanwhile, a restoring member 66 such as a spring or rubber strip is connected between the bottom of the opening and closing cover 65 and the inner side wall of the water collecting cylinder 62, and the restoring member 66 can drive the opening and closing cover 65 to slide towards the direction away from the roof structure 2.

[0075] When rainwater enters the water collecting cylinder 62 and accumulates to a certain amount, the opening and closing cover 65 is driven to move downwardly by the gravity of the rainwater, and the opening and closing cover 65 moves to abut against the lower edge of the position where the water collecting cylinder 62 is communicated with the flow guide pipe 63, so as to close the opening below the water collecting cylinder 62 and further prevent the rainwater from directly contacting the standing seam roof panel 24. After the opening below the water collecting cylinder 62 is closed, the rainwater is drained along the flow guide pipe 63 to the drain pipe 64; after the water in the containing groove 651 is dried, the restoring member 66 drives the opening and closing cover 65 to return to the initial position, so as to open the opening below the water collecting cylinder 62, and air can flow along the water collecting cylinder 62 to the surface of the standing seam roof panel 24, which can effectively reduce the noise of rainwater and ensure the normal ventilation of the surface of the standing seam roof panel 24.

[0076] The above are the preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Any equivalent changes made according to the structure, shape and principle of the present application shall be covered within the protection scope of the present application. For example, the materials of the sound absorbing layer 22 and the thermal insulation board 23 can be replaced according to actual needs, and the shape and connection mode of the adapter 3 and the support can also be appropriately adjusted, as long as these changes do not deviate from the core idea and principle of the present application, and shall be considered as covered within the protection scope of the present application.
