Embodiment
[0021] During specific implementation, follow the steps below for construction:
[0022] (1) Positioning and setting out
[0023] According to the shape and size of the building roof, determine the position of the exhaust groove 4, then carry out the construction of the slope layer 1 and the insulation layer 3, and leave the exhaust groove 4 during the construction of the insulation layer 3; the exhaust groove 4 includes a group of longitudinal grooves and a Set of horizontal grooves, vertical grooves and horizontal grooves perpendicular to each other. Set the exhaust device at the vertical intersection of the longitudinal groove and the horizontal groove in the middle of the 36 square meter range.
[0024] (2) Fabrication of exhaust pipe components
[0025] The exhaust pipe assembly is composed of two connecting pipes 9, two 90-degree elbows 10, a tee 8 and a vertical pipe 7; all the above-mentioned parts are PVC pipe fittings with a nominal diameter of φ50mm, of w...

The invention discloses a method and device for preventing mildewing of a top indoor ceiling of a building. According to the method, an air exhaust pipe assembly is arranged within the range of each 36 square meters of the roof of the building, air inlets of the air exhaust pipe assemblies extend into a thermal insulation layer between a slope finding layer and a waterproof layer of the roof, criss-cross air exhaust ducts are arranged on the thermal insulation layer, and the air inlets of the air exhaust pipe assemblies are located at the intersections of the criss-cross air exhaust ducts. By means of the method of arranging an air exhaust device on the roof of the building, moisture between the slope finding layer and the waterproof layer of the roof of the building can be discharged in time, dryness between the slope finding layer and the waterproof layer of the roof of the building is kept, moisture can be prevented from permeating the indoor space and prevented from causing mildewing to the indoor ceiling of the roof of the building. By means of the method and the device, cost can be reduced, the construction period is shortened, and the method and the device have important significance in durability of the roof structure and attractiveness of the building. Compared with a device manufactured through a traditional construction method, the device has the advantages of being easy to manufacture, convenient to construct, low in cost, attractive in appearance and the like.
Description
technical field [0001] The invention relates to a method and a device for preventing indoor ceiling mildew on the top floor of a building, and belongs to the technical field of roof exhaust in building construction. Background technique [0002] An insulation layer is generally provided on the slope-finding layer of the building roof, and a waterproof layer is arranged on the insulation layer. Since the insulation layer of the slope-finding layer and the waterproof layer is usually made of a low-density air-permeable material, water will enter the insulation layer in rainy days, and the moisture after the water evaporates can only be discharged from the gap at the edge of the waterproof layer. Poor, the damp gas will become moldy between the slope-finding layer and the waterproof layer, and will gradually penetrate into the top-floor room, causing mildew on the top-floor indoor ceiling of the building, affecting the appearance of the room. Contents of the invention [000...
