Embodiment 1

[0123] The integrated construction process of passive thermal bridge-free sloping roof with a thickness of 300 mm and thermal insulation and decoration provided in this example is as follows:

[0124] Base treatment → 20mm 1:3 cement mortar leveling → cold base oil → 1.5 thick aluminum foil surface self-adhesive modified asphalt vapor barrier membrane → high-density graphite polystyrene board double-layer staggered seam PU glue bonding → 3 thick SBS modification Asphalt self-adhesive waterproof membrane → geotextile → fine stone concrete nail-holding layer → fixed vertical tile strip → roof tile → completion cleaning and acceptance

[0125] Specifically, the following steps are included:

[0126] (1) Acceptance and cleaning of the base layer: Since the deviation of the flatness and compactness of the roof insulation layer largely depends on the base layer, in order to ensure the quality of the insulation project, the insulation layer is required to be laid on a solid and flat ...

Abstract

The invention discloses a heat preservation and decoration integrated construction process for a passive heat-bridge-free pitched roof with the thickness of 300 mm. The heat preservation and decoration integrated construction process comprises the following steps of (1) acceptance and cleaning of a base layer; (2) arrangement of a waterproof vapor-proof layer; (3) arrangement of a heat preservation layer; (4) arrangement of a fine aggregate concrete protection layer; and (5) laying of roof tiles. By applying the heat preservation and decoration integrated construction process, energy loss in an operation stage is reduced, thermal insulation performance is stable, waterproofness is good, various experimental results meet the design requirements, good economic benefits and social benefits are obtained, the building energy-saving efficiency can be greatly improved, and a national energy-saving strategy is greatly promoted.

Description

technical field [0001] The invention relates to a 300mm-thick thermal insulation and decoration integrated construction process for a passive athermal bridge slope roof, belonging to the technical field of building construction. Background technique [0002] Passive House, also known as Passive House. Compared with traditional buildings, passive houses can achieve energy saving of more than 90% through the comprehensive use of various energy-saving technologies, which minimizes the dependence on active energy consumption. Because the traditional thermal insulation construction cannot meet the requirements of the roof heat transfer coefficient K value. Therefore, 300mm thick graphite polystyrene board has become a common insulation material for passive houses. Our project department has achieved good results through two engineering applications, and summarized the construction method of a passive 300mm thick thermal insulation and decoration integrated roof without thermal ...
