Active breathing moisture-proof and steam-exhausting inverted roof system and its construction method

Abstract

An active breathing type moisture-proof and steam-exhausting inverted roof system comprises a roof structure layer and a roof leveling layer, a roof waterproof layer, a roof insulation layer, a roof slope finding layer and a roof rigid protective layer which are sequentially arranged on the roof structure layer from the inside to the outside. The roof is composed of an active breathing moisture-proof and steam exhaust system composed of a breathing pipe network system and an unpowered hood device; the breathing pipe network system arranged on the waterproof layer is an air flow channel, including an air outlet breathing riser, and a joint through joints. The connected breathing cross pipe and the breathing vertical pipe, and the T-shaped air intake breathing pipe connected with the breathing cross pipe and the breathing vertical pipe and extending out of the roof through the joint; the unpowered hood device includes a turbine hood fan blade group and a hood support , the hood blade group is sleeved on the hood support through the rotating shaft; the hood support is sleeved into the upper part of the air-exhaust breathing riser and fixed on the roof; the roof system has a reasonable structure, has an active steam exhaust function, and has a good steam exhaust effect, which can greatly reduce the roof. possibility of leakage.

Description

Technical field [0001] The invention relates to a roof moisture-proof exhaust steam system and a construction method thereof, in particular to an active breathing type moisture-proof exhaust steam inverted roof system and a construction method thereof. Background technique [0002] Roofing engineering is an important sub-item of construction engineering, and its construction quality directly affects the function of the building. Because the insulation layer of the bottom layer of the roof ceiling can absorb and retain water, it is difficult to find the specific leakage point once leakage occurs. At this time, the roof can only be renovated at a high price or the cumbersome repairing construction is carried out everywhere, so the engineering Quality control is particularly important. [0003] In traditional construction, the roofing method is usually that the waterproof layer is above the insulation layer and the slope-finding layer, but this approach makes the roof waterproof laye...

AI Technical Summary

Problems solved by technology

[0004] 1. It is close to the atmosphere and is easily affected by the alternating temperature difference, which will cause cracks in the protective layer and cracking and failure of the waterproof layer of the membrane

[0005] 2. There are often many large-scale equipment on the roof. During its transportation, installation and use, it is easy to crush the waterproof layer on the fragile insulation layer and make it invalid

[0006] 3. The slope-seeking layer is a wet operation. In actual construction, it is easily affected by the amount of concrete and the climate. The moisture content of the base layer is often difficult to control, resulting in a large amount of water vapor stored in it, which affects the construction speed, quality and life of the subsequent waterproof layer.

[0007] 4. If the water that leaks or remains in the slope layer and the insulation layer cannot be removed in time, the waterproof layer will be destroyed due to the expansion of high-temperature steam

[0008] In view of the above problems 3 and 4, although the current practice also adopts the method of burying vertical or vertical and horizontal exhaust pipes on the roof to solve the problem of roof exhaust, but because they are all passive exhaust that rely on the strong temperature difference between the inside and outside of the roof However, the effect is often unsatisfactory, and there will still be too much water in the roof and then leakage.
