TECHNICAL FIELD
[0001] The present application relates to the field of building technology, in particular to a roof interlayer water vapor discharge device and construction method. BACKGROUND
[0002] The concrete roof insulation layer is prone to water storage. In summer, the water changes into water vapor when the temperature is high. The water vapor cannot be discharged, which easily leads to arching and cracking of the concrete protective layer of the roof. In current construction engineering, the roof contains a waterproof layer, an isolation layer, an insulation layer and a concrete protective layer. Water or water stains cannot be completely discharged in each layer above the waterproof layer and below the concrete protective layer. In addition, the concrete protective layer has cracks, which leads to rainwater entering. When the temperature is too high in summer, the water changes into water vapor, which easily leads to arching and cracking of the concrete protective layer. This may affect the service life of the roof waterproof layer and lead to roof water seepage. Therefore, the water vapor inside needs to be discharged. At present, the roof venting groove is filled with pebbles, and the upper part is covered with a waterproof roll. The construction speed is slow, the material procurement is difficult, the construction is inconvenient, and the cost is high. The roof venting device is made of stainless steel plate, galvanized sheet and PVC material to ensure its strength. The manufacturer can produce in batches, which is convenient for procurement and transportation on site. The on-site assembly is simple. Solar energy is used to accelerate the discharge of water vapor in the venting layer. The installation is beautiful, and the construction saves labor and material costs.
[0003] Therefore, the building roof venting system device and construction method can effectively discharge the water vapor in the building insulation layer to avoid arching and cracking of the concrete protective layer of the roof due to the inability to discharge water vapor. The present application aims to provide a roof venting system construction method that is convenient and fast, uses clean solar energy to accelerate the discharge of water vapor in the interlayer, reduces the risk of cracking and maintenance, and effectively saves costs.

The water vapor flows from the pebble gap to the standpipe, and the standpipe is naturally discharged. The standpipe is fixed by mortar. If the workers are not careful during the pouring of the concrete protective layer of the roof, the standpipe may be inclined, and the concrete may flow into the pipe, causing blockage. SUMMARY

[0050] Step five, connect the straight pipe 5 with the fan blade 11 with the other end of the elbow pipe 4;
[0051] Step six, install the solar panel 6 above the elbow pipe 4;
[0052] Step seven, connect the electric wire 7 to connect the solar panel 6 and the motor driving the fan blade 11.
[0053] Working principle: The venting pipe head 1 is arranged at the intersection of each partition joint, is hollow inside and is provided with four slots 9 in the horizontal direction for connecting the horizontal venting groove pipe 2.

[0054] When the temperature rises, the moisture in the insulation layer is converted into water vapor, enters the horizontal venting groove pipe 2 through the vent hole 10, and then flows into the venting pipe head 1 along the groove pipe. The venting pipe head 1 is internally provided with a protrusion 12 with a structure of wide at the bottom and narrow at the top, which helps to guide the airflow to flow upward, reduce airflow conflict and improve exhaust efficiency.
[0055] Then, the water vapor enters the exhaust vertical pipe 3 from the vertical pipe interface 8 at the top of the venting pipe head 1, and is guided to the straight pipe 5 through the elbow pipe 4 bent by 180 degrees.
