The ridge ventilator uses the power generated by the temperature difference between indoor and outdoor to promote the circulation of indoor air and effectively promote the ventilation of the indoor space. As a professional smoke vent manufacturer, Mcwell will introduce the precautions for the production of steel roof ridge vent.

(1) The ridge ventilator is composed of a frame, a peripheral guard plate, an end plate, a rainproof plate, a flooding plate, a drainage groove, etc.

(2) The rain shield should be able to effectively prevent rainwater from entering the room and be able to withstand long-term rain erosion. The drainage trough can collect and hold the rainwater on the rain shield and deflector during the maximum rainfall, and quickly drain the rainwater through the downpipe , To ensure that rainwater cannot enter the plant. 

(3) The flooding board should be able to drain the rainwater out of the roof waterproof layer, and at the same time, it must be able to prevent the roof rainwater from splashing into the room.

(4) The welding of the steel roof ridge vent frame should be leveled and straight, with a diagonal error of ±1.5mm per meter, and the warping of the frame plane should not be greater than 5.0mm. The installation of the roof ridge vent is combined with the longitudinal unit of 3m and the shaft, that is, the spacing of the skylight frame is 3000mm. When the combined length is longer, two inspection holes are provided every 60m, and the height of the ventilation skylight is >2m, and an inspection ladder should be installed at the end. . The overhaul holes and overhaul ladders are all made by the manufacturer. The components made of section steel and plates must be straight. The burrs caused by cutting should be removed, and the acute angles formed should be blunt to ensure that the surface after installation is smooth and without acute angles. 

(5) Welding connection is adopted between roof ventilation skylight and foundation. 

(6) The main connections of the factory roof ventilator should be bolted, all bolts must be high-strength galvanized bolts, brackets and other accessories must be galvanized, and the size of the bracket must meet the requirements of the national standard. When assembling and installing, all fastening parts must be Tighten, no looseness is allowed, and the steel structure connection should conform to the national steel standard. 

(7) Ventilation skylights on the roof must be equipped with small maintenance doors, maintenance holes, and maintenance ladders in accordance with the requirements of the atlas. 

(8) The frame and panel are connected by self-tapping screws + washers. The self-tapping screws and washers are made of stainless steel (1Co18Ni9Ti). The self-tapping screws have high-quality plastic caps. The area between 23-37 lines is air-cooled. The number of self-tapping screws for roof ventilation skylights must be encrypted
