Fig. 1 shows a main body structure diagram of a roof drainage structure according to an embodiment of the present application. As shown in fig. 1, the roof drainage structure includes: a sump 100, a rainwater pipe 200, and an overflow pipe 300. The water collecting tank 100 is matched with the gutter, the water collecting tank 100 is suitable for being arranged on the inner side wall of the attached gutter, and sealant is arranged at the joint of the water collecting tank 100 and the gutter. The downspout 200 is located the opening one side that deviates from of water catch bowl 100, and the one end of downspout 200 and the inside cavity intercommunication of water catch bowl 100, the other end of downspout 200 is applicable to the rainwater drainage. The overflow pipe 300 is located at the same side of the water collection tank 100 as the rainwater hopper 210, the overflow pipe 300 penetrates through the side wall of the water collection tank 100, one end of the overflow pipe 300 is located in the inner cavity of the water collection tank 100, and the other end of the overflow pipe 300 is suitable for draining rainwater.

This application is applicable to and carries out the drainage to the roofing. Through setting up and gutter assorted water catch bowl 100, install water catch bowl 100 laminating gutter, carry out the water conservancy diversion to the rainwater and discharge. The rain pipe 200 is communicated with the bottom of the water collecting tank 100 and is used for discharging the rain water collected by the water collecting tank 100. The end of intaking of overflow pipe 300 is located the inside cavity of water catch bowl 100, make the bottom that the water catch bowl 100 was visited to the one end of intaking of overflow pipe 300, when downspout 200 is unblocked, the water level in the water catch bowl 100 is less than the one end of intaking of overflow pipe 300, the rainwater only outwards discharges through downspout 200, guarantee that normal drainage can not pass through overflow pipe 300, reduce overflow pipe 300 and take place the risk of blockking up, when downspout 200 takes place to block up or the precipitation is too big to lead to when downspout 200 can not in time discharge, the inside water level of water catch bowl 100 rises, the water level rises to overflow pipe 300 water intake end, overflow pipe 300 begins to discharge the rainwater, make the rainwater can not overflow and take place the seepage.

Wherein, water catch bowl 100 comprises waterproofing membrane, and waterproofing membrane directly lays and forms the flute profile structure on the inner wall of gutter, and overall structure is comparatively simple, the effectual construction degree of difficulty that has reduced. Further, still be equipped with 10mm to 30mm thick protection mortar on the waterproofing membrane to the life of this application is prolonged.

Here, it should be noted that the distance between the water inlet end of the overflow pipe 300 and the bottom of the water collecting tank 100 is smaller than the distance between the top end of the side wall of the water collecting tank 100 and the bottom of the water collecting tank 100, so as to further ensure that the rainwater can be drained through the overflow pipe 300 before overflowing the water collecting tank 100.

In one possible implementation, a fascia 400 is also included. The cornice 400 is adapted to cover a roof arrangement with a side of the cornice 400 being connected to the edge of the opening of the water collection gutter 100. Rainwater collected by the cornice 400 directly flows into the water collection gutter 100 by connecting the cornice 400 to the edge of the opening of the water collection gutter 100.

In one possible implementation, the storm water pipe 200 is provided with a storm water hopper 210. The rainwater pipe 200 communicates with the sump 100 through a rainwater hopper 210. The rainwater hopper 210 is located inside the water collecting tank 100, the rainwater hopper 210 is communicated with the water inlet end of the rainwater pipe 200, so that rainwater flows into the rainwater pipe 200 through the rainwater hopper 210, and the grid of the rainwater hopper 210 can block large sundries and reduce the blockage of the rainwater pipe 200.

In a possible implementation manner, a preset distance H is provided between one end of the overflow pipe 300 located in the inner cavity of the water collecting tank 100 and the water collecting tank 100. The preset distance H is 20cm to 40cm, so that the distance is reserved between the water inlet end of the overflow pipe 300 and the bottom of the water collecting tank 100, and the overflow pipe 300 is prevented from draining water during normal drainage.

In one possible implementation, the heights of the two opposite side walls of the water collection tank 100 are both greater than the preset distance H. Assorted, the degree of depth of water catch bowl 100 is 45cm to 60cm, compares in traditional gutter structure, and this application is through setting up darker water catch bowl 100 to reinforcing drainage ability.

Here, it should be noted that the width of the water collecting tank 100 is 40cm to 60, the rainwater storage capacity of the water collecting tank 100 is further increased,

in one possible implementation, the gutter 400 is arranged obliquely, with one end of the gutter 400 protruding out of the side wall of the water collection tank 100 towards the inner cavity of the water collection tank 100. The whole structure is simple, and the production cost is effectively reduced.

In a possible implementation mode, the overflow pipe 300 is close to the cornice 400, and the one end of the overflow pipe 300 located in the inner cavity of the water collecting tank 100 faces the extending part of the cornice 400, so that the extending part of the cornice 400 is located above the overflow pipe 300, and the water inlet end of the overflow pipe 300 can be protected.

In one possible implementation, a parapet wall 500 and a mounting wall 600 are also included. The parapet wall 500 and the installation wall 600 are oppositely arranged on the roof, a gutter is formed between the parapet wall 500 and the installation wall 600, and the height of the installation wall 600 is smaller than that of the parapet wall 500. The opposite sides of the water collecting channel 100 are respectively attached to the parapet wall 500 and the installation wall 600, and the height of the water collecting channel 100 near the parapet wall 500 is greater than that of the water collecting channel 100 near the installation wall 600. Through setting up parapet 500 and installation wall 600, form the gutter structure with the roofing, the lateral wall of water catch bowl 100 is attached respectively on parapet 500, roofing and installation wall 600's lateral wall, and overall structure is comparatively simple, the effectual manufacturing cost that has reduced.

In one possible implementation, the fascia 400 is secured to the top end of the mounting wall 600. The gutter plate 400 is fixed to the top end of the installation wall 600 by fixing brackets 420, so that rainwater on the gutter plate 400 flows to the gutter between the installation wall 600 and the parapet wall 500.

Here, it should explain that, being close to of water catch bowl 100 installs 600 one side opening part edge, buckle towards installation wall 600, and the outside seepage can not be passed through to the further top fixed connection who guarantees the rainwater of department of buckling and installation wall 600, and water catch bowl 100 is buckled and is connected through sealed glue between department and the cornice 400, has further strengthened the waterproof performance of this application.

Here, the eaves plate 400 is a profiled steel plate. The application of itself still includes purlin 700, fixes cornice 400 on the roofing through purlin 700, and purlin 700 sets up according to actual conditions.

Further, cornice 400 is equipped with cornice end cap, and cornice end cap is located the wave form of profiled sheet and the gap between purlin 700, prevents that the rainwater from flowing into indoorly along the profiled sheet, has improved the waterproof performance of this application.

In one possible implementation, the cornice 400 is provided with a drip plate 410. The drip plate 410 is located at a protruding portion of the gutter 400, and the drip plate 410 is disposed at a side of the gutter 400 facing the water collection tank 100. By providing the drip plate 410, rainwater is prevented from flowing into the room along the profiled steel sheet, and if the rainwater meets the drip plate 410, the rainwater drips into the water collection tank 100 along the lower edge of the drip plate 410.
