Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example (b):

a roof drainage is with mouth waterproof construction that falls, refers to figure 1, includes the roof body 1 and runs through the water service mouth 101 that the roof body 1 thickness direction set up. The roof body 1 is a roof of a building, and the water through holes penetrate through the top wall and the bottom wall of the roof body 1, so that rainwater on the roof body 1 can be discharged downwards after penetrating through the roof.

Referring to fig. 1, the upper surface of the roof body 1 is provided with an additional layer 102, the additional layer 102 is a waterproof coating formed by coating high polymer modified asphalt slurry on the upper surface of the roof body 1, and the material of the additional layer is insoluble in water so as to reduce the phenomenon that rainwater seeps into the roof body 1, and then the rainwater seeps downward and enters the room.

Referring to fig. 1, the surface of the additional layer 102 away from the roofing body 1 is provided with a layer of waterproof layer 103, and the material of the waterproof layer 103 is preferably a synthetic polymer waterproof roll material, which further reduces the phenomenon that rainwater permeates into the inner cavity of the roofing body 1 and seeps into the room downward by reducing rainwater infiltration in cooperation with the additional layer 102.

Referring to fig. 1, the guiding surface 104 is obliquely arranged on the inner side wall of the water through opening 101 and positioned at the top of the inner side wall, and the guiding surface 104 greatly increases the speed and efficiency of rainwater on the upper surface of the roof body 1 flowing into the inner cavity of the water through opening 101, so that the retention time of the rainwater on the upper surface of the roof body 1 is reduced, and the phenomenon of rainwater infiltration is further reduced.

Referring to fig. 1 and 3, a stop collar 105 is integrally formed on the inner side wall of the water passage 101 and located at the bottom along the horizontal direction, a water passing member 2 is arranged on the inner side wall of the water passage 101, the water passing member 2 is preferably a water bucket subjected to anti-rust treatment, and one end of the water passing member away from the roof body 1 is connected with a water pipe (not shown in the figure) to quickly discharge rainwater collected in the inner cavity of the water passing member 2. The periphery of the top of the water passing piece 2 is matched with the inner side wall of the water passing opening 101, and the periphery size of the top is far larger than that of the bottom of the water passing opening, so that the limiting ring sleeve 105 is clamped, and the position of the water passing piece 2 on the inner side wall of the water passing opening 101 is further limited.

Referring to fig. 2 and 3, a plurality of abutting strips 3 are welded on the outer side wall of the water passing piece 2 at intervals along the height direction of the water passing piece, and the cross section of each abutting strip 3 is in a dovetail groove shape. The clamping groove 106 that is equal to the number of the butt strips 3 is longitudinally arranged on the upper surface of the roof body 1 and on the end of the guide surface 104 close to the water gap 101, the inner side wall of the clamping groove 106 is matched with the periphery of the butt strips 3, so that the butt strips 3 are inserted, the water passing piece 2 is stably inserted into the inner side wall of the water gap 101, and the water passing piece is not easy to loosen. In this embodiment, after the water passing member 2 is fixed to the inner cavity of the water passing port 101, the operator needs to seal the top of the engaging groove 106 with a waterproof material to reduce the penetration of rainwater into the inner cavity of the engaging groove 106.

Referring to fig. 3, the water passing member 2 is provided with a plurality of settling tanks 201 at intervals along the longitudinal direction at the position where the abutting strip 3 passes through the side wall, and the fixing members 202 are arranged on the inner side wall of the settling tanks 201. The fixing member 202 is preferably a steel cement nail which penetrates the water passage member 2 at the settling tank 201 and extends into the roof body 1, so that the water passage member 2 is more stably fixed to the inner side wall of the water passage opening 101.

Referring to fig. 3, an inner caulking groove 301 is formed in the outer side wall of the abutting strip 3 and at one end of the abutting strip far away from the water passing piece 2, and an interference sleeve 4 is arranged on the inner side wall of the inner caulking groove 301. The interference fit 4 is preferably made of soft and easily deformable rubber and has a thickness greater than the depth of the inner caulking groove 301 so as to protrude from the outer surface of the abutting strip 3. When the butt strip 3 inserts the block groove 106 inner chamber, interference cover 4 atress deformation and compression, and then crowd and account for the space between butt strip 3 and the block groove 106 to improve the tight degree of connection of water passage spare 2 at the water service opening 101 inside wall, and then reduce the space to appear between the two, and make the phenomenon of rainwater seepage from the space.

Referring to fig. 4, a plurality of deformation cavities 401 are arranged at intervals inside the interference sleeve 4, and the deformation cavities 401 extend along the thickness direction of the interference sleeve 4. The deformation cavity 401 makes the interference sleeve 4 become more flexible to increase the deformation area after being stressed, and further improve the connection tightness of the abutting strip 3 on the inner side wall of the clamping groove 106.

Referring to fig. 3, the surface of the interference sleeve 4 away from the embedded groove 301 is provided with a plurality of step grooves 402 at intervals along the longitudinal direction, and the inner side walls of the step grooves 402 are provided with locking pieces 403. The locking member 403 is preferably a self-tapping screw which penetrates the interference fit 4 and is screwed into the abutment bar 3 so that the interference fit 4 is more tightly fixed to the inner side wall of the inner caulking groove 301.

The working principle is as follows:

the waterproof layer 103 and the additional layer 102 are attached to the upper surface of the roof body 1 from top to bottom to reduce the phenomenon that rainwater seeps down into the room. The guide surface 104 is used for increasing the flow rate of rainwater entering the inner cavity of the water through port 101, so as to reduce the time for rainwater to stay on the upper surface of the roof body 1, and further reduce the phenomenon that rainwater permeates into the roof body 1 and leaks downwards.

The butt strip 3 with the interference sleeve 4 is inserted into the inner cavity of the clamping groove 106, so that the outer edge of the water passing piece 2 is tightly attached to the inner side wall of the water passing opening 101, the gap between the water passing piece 2 and the water passing opening 101 is effectively reduced, and the phenomenon that rainwater leaks downwards through the gap between the water passing piece 2 and the water passing opening 101 is further reduced.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
