Detailed Description

The following describes the present invention in further detail with reference to the accompanying drawings. These embodiments are provided only for illustrating the present invention and are not intended to limit the present invention.

In the description of the present invention, it should be noted that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

In addition, in the description of the present invention, "a plurality" means two or more unless otherwise specified.

As shown in fig. 1, 2 and 3, drain holes 1 are formed in the bowl bottom of the concave bowl-shaped net rack roof, namely the lowest part of the bowl-shaped net rack roof, the number and the size of the drain holes 1 can be calculated according to the gap between single aluminum alloy roof panels or the opening of a direct roof panel in the net rack roof in specific engineering, and the water discharge amount of the drain holes can be calculated according to the water collection amount and the opening amount of the roof.

As shown in fig. 4, a header tank 2 is provided below the drain hole 1, and a rectangular section reinforced concrete beam in the header tank 2 is shown as an illustration only, and the header tank 2 may be arranged across the beam. The siphon gutter inlet 3 is embedded at the bottom of the box. An overflow opening 7 can be arranged above the side wall of the water collecting tank 2, and when the water level of rainwater in the water collecting tank 2 is higher than the lower edge of the overflow opening, the rainwater can overflow through the overflow opening 7. The overflow port has the effect that when the actual rainfall exceeds the designed rainfall, the drainage capacity of the siphon rainwater hopper reaches the maximum value, and in order to prevent untimely drainage of roof rainwater, the excessive rainwater can be directly drained through the overflow port and drained to ground water in a free drainage mode.

The siphon drainage pipe comprises a horizontal siphon drainage pipe 5 and a vertical siphon drainage pipe 4, the upper end of the vertical siphon drainage pipe 4 is connected with the siphon gutter inlet 3 embedded in the bottom of the water collecting tank 2, and the other end of the vertical siphon drainage pipe is connected with the horizontal siphon drainage pipe 5; horizontal pipe 5 of siphon drainage is laid in the horizontal piping lane of bowl form rack roofing below, and horizontal pipe 5 of siphon drainage is converted into the riser along the outer wall behind horizontal piping lane to the building both ends and is fallen to arrange to outdoor rainwater energy dissipation well. The usable bowl form rack roofing below of horizontal piping lane is equipped with horizontal packway 6, and packway 6 can be done as the piping lane simultaneously promptly. The corridors are walkways which are arranged in large-scale performance buildings, exhibition buildings and sports buildings and are used for workers to walk and work at high altitude for the workers to arrange auxiliary facilities such as lamplight, sound, stage machinery and the like. The number and the size of the siphon rainwater inlet 3 and the siphon drainage vertical pipe 4 can be determined by calculation according to a pressure flow siphon rainwater system. The horizontal siphon drainage pipe 5 can be laid along the packway of the building to the end part of the building according to local conditions and then converted into a vertical pipe to fall along the outer wall. The pipe laying layout of the horizontal siphon drainage pipe 5 can be arranged according to the streets of specific projects or directly arrange pipe galleries to drain rainwater to the end parts of the whole building.

The building vertical force-bearing member 8 shown in fig. 4 is only one illustration.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and replacements can be made without departing from the technical principle of the present invention, and these modifications and replacements should also be regarded as the protection scope of the present invention.
