Buried type heat preservation and insulation roof steam exhaust system and construction method thereof

Abstract

According to the hidden type heat preservation and insulation roof steam exhaust system and the construction method thereof, a heat preservation layer is arranged on a waterproof layer, and a steam exhaust pipe network formed by steam exhaust pipes of an improved structure is laid in the heat preservation layer, so that the steam exhaust problem of the heat preservation layer is effectively solved; roofing cracking and bulging caused by volume deformation caused by thermal expansion and cold contraction of the thermal insulation layer can be effectively relieved, and the waterproof performance and the thermal insulation performance of the thermal insulation roofing are guaranteed; water vapor in the heat preservation layer can be effectively discharged, roof bulging and cracking caused by thermal expansion and cold contraction of the heat preservation layer can be effectively prevented, and the waterproof and heat preservation effects of the heat preservation and heat insulation roof are guaranteed.

Problems solved by technology

[0002] The thermal insulation roof needs to play the role of water release and heat preservation. It is necessary to set up a waterproof layer and an insulation layer at the same time. In order to prevent water from entering the roof, the insulation layer is often set on the lower layer and the waterproof layer is set on the outer layer. Affected by thermal expansion and contraction, when the season changes, especially the thermal expansion and contraction of the insulation layer is more obvious, it is easy to cause the waterproof layer to deform and crack due to the change in the volume of the insulation layer

[0003] In addition, most of the materials used in the current insulation layer are water-absorbent, and it is difficult to drain the moisture in the insulation layer before construction (before laying the waterproof layer) in the rainy season or in an environment with high humidity. When the temperature rises, it will expand, which will seriously affect the roof insulation and waterproof structure, and the insulation layer or waterproof layer will crack. Therefore, the exhaust pipe is often embedded in the insulation layer to discharge the water vapor.

Some use open pipes to directly extend the exhaust pipe from the roof; some use hidden pipes to discharge the exhaust pipe from the side of the house, but no matter which exhaust method will inevitably lead to thermal expansion of the exhaust pipe itself The impact of cold shrinkage on the insulation layer, and the current exhaust pipes mostly use round pipes, it is difficult to ensure complete exhaust steam, and even cause water vapor to stay in the exhaust pipe
