AI Technical Summary
In the existing ventilation structure, the exhaust duct vibrates when the fan is working, destroying the sealing structure and causing water leakage on the roof.
Z-shaped baffle and L-shaped baffle are used. Z-shaped baffle is used to block rainwater above, and L-shaped baffle is used to block rainwater and flow diversion on the side. It is fixedly connected to the exhaust air duct through a spot welding structure, and is filled with weather-resistant structural glue at the connection.
It effectively prevents external rainwater from entering the factory, and uses stainless steel waterproof panels to increase the sealing effect on the roof, preventing rainwater from entering due to backflow.

Abstract
Description
Technical Field
[0001] The present invention relates to the field of waterproof structures, and particularly to a waterproof structure for an exhaust air duct on the roof of a factory building. Background Art
[0002] In existing ventilation structures, corrugated steel plates are used to build factory buildings, and fans are installed in the corrugated steel plate factory buildings. The exhaust port of the fan is connected to the bottom of the exhaust air duct, and the top of the exhaust air duct penetrates through the roof of the corrugated steel plate factory building. In order to prevent rainwater and the like from entering the factory building through the connection between the exhaust air duct and the roof, the existing method is to set a sealing structure at the connection between the two. However, when the fan is working, it will drive the exhaust air duct connected to it to vibrate, thereby damaging the sealing structure and causing the roof to leak.
[0003] Therefore, it is necessary for us to improve such a structure to overcome the above defects. Summary of the Invention

[0017] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the drawings and specific embodiments.
[0018] As Figure 1 , Figure 2 and Figure 3 shown, a waterproof structure for the exhaust air duct on the roof of the factory building proposed by the present invention includes a factory building 1 and an exhaust air duct 2. The exhaust air duct 2 is arranged in the factory building 1, the top of the exhaust air duct 2 penetrates through the inclined roof of the factory building 1, a first waterproof structure 3 is provided on the lower inclined side of the exhaust air duct 2, and a second waterproof structure 4 is provided on the upper inclined side of the exhaust air duct 2;
[0019] The first waterproof structure 3 includes a Z-shaped baffle 5 and an L-shaped baffle 6. The connecting part of the Z-shaped baffle 5 is fixedly arranged on the outer side wall of the exhaust air duct 2, and the rain-blocking part of the Z-shaped baffle 5 extends outward; the L-shaped baffle 6 is arranged at the inclined roof below the Z-shaped baffle 5, the rain-blocking edge of the L-shaped baffle 6 is located between the rain-blocking part of the Z-shaped baffle 5 and the outer side wall of the exhaust air duct 2, and the diversion part of the L-shaped baffle 6 extends along the lower inclined side of the inclined roof of the factory building 1;
[0020] The second waterproof structure 4 includes a Z-shaped baffle 5, an L-shaped baffle 6, and a stainless steel waterproof plate 7. The connecting part of the Z-shaped baffle 5 is fixedly arranged on the outer side wall of the exhaust air duct 2, and the rain shielding part of the Z-shaped baffle 5 extends outward; the L-shaped baffle 6 is arranged at the inclined roof below the Z-shaped baffle 5, and the retaining edge of the L-shaped baffle 6 is located between the rain shielding part of the Z-shaped baffle 5 and the outer side wall of the exhaust air duct 2, and the guiding part of the L-shaped baffle 6 extends along the upper inclined side of the inclined roof of the factory building 1; the stainless steel waterproof plate 7 is arranged along the guiding part of the L-shaped baffle 6 and extends to the wall 10.
[0021] The Z-shaped baffle 5 is fixedly connected to the exhaust air duct 2 through a spot welding structure, and weather-resistant structural adhesive is filled at the connection between the Z-shaped baffle 5 and the exhaust air duct 2.
[0022] A base 8 is provided in the factory building 1, and a fan 9 is installed on the base 8. The bottom of the exhaust air duct 2 is connected to the exhaust port of the fan 9.
[0023] The working principle of the first waterproof structure of the present invention is as follows:
[0024] When it rains, the rainwater falling from above will be blocked by the Z-shaped baffle 5 and flow down along the Z-shaped baffle 5 to reach the L-shaped baffle 6 located below the Z-shaped baffle 5. Since the first waterproof structure is arranged on the lower inclined side of the inclined roof, the rainwater finally flows away along the inclined roof of the factory building 1 along the guiding part of the L-shaped baffle 6.
[0025] The working principle of the second waterproof structure of the present invention is as follows:
[0026] When it rains, the rainwater falling from above will be blocked by the Z-shaped baffle 5 and flow down along the Z-shaped baffle 5 to reach the L-shaped baffle 6 located below the Z-shaped baffle 5. Since the first waterproof structure is arranged on the upper inclined side of the inclined roof, its flow direction will be blocked by the retaining edge of the L-shaped baffle 6 and flow to the front and rear of the inclined roof. At the same time, in order to increase the sealing effect at the roof, a stainless steel waterproof plate 7 is arranged along the guiding part of the L-shaped baffle 6, avoiding the rainwater from flowing back into the factory building.
