Spraying rigid foam polyurethane heat preservation fireproof structure and construction technology thereof
The invention relates to the technical field of building heat preservation and energy conservation and outer wall heat preservation construction, in particular to a hard foam polyurethane spraying heat preservation fireproof structure and a construction technology thereof. Comprising a base layer wall body, a heat preservation layer is fixed to the outer side of the base layer wall body, an interface layer is fixed to the outer side of the heat preservation layer, a light plastering layer is fixed to the outer side of the interface layer, an anti-crack layer is arranged in the outer side of the light plastering layer, a plastering layer is fixed to the outer side of the anti-crack layer, and an anti-crack layer is arranged in the plastering layer. According to the spraying rigid foam polyurethane heat preservation fireproof structure and the construction technology thereof, the rigid foam polyurethane is sprayed on site, firm bonding with the base layer wall is achieved through the cohesiveness of the polyurethane, and a heat preservation system is prevented from falling off; the light plaster layer is adopted as the fire-resistant layer and the protective layer of the rigid foam polyurethane, and when the thickness of the light plaster layer is larger than or equal to 40 mm, the system can be equivalent to an A-level structural system and is not limited by the application height.
本发明涉及建筑保温节能和外墙保温施工技术领域，尤其涉及一种喷涂硬泡聚氨酯保温防火结构及其施工工艺。包括基层墙体，所述基层墙体的的外侧固定有保温层，所述保温层的外侧固定有界面层，所述界面层的外侧固定有轻质抹灰层，所述轻质抹灰层外侧的内部设置有抗裂层，所述抗裂层的外侧固定有抹面层，所述抹面层的内部设置有抗裂层。本发明提供的一种喷涂硬泡聚氨酯保温防火结构及其施工工艺，通过采用现场喷涂硬泡聚氨酯，利用聚氨酯自身的粘结性与基层墙体实现牢固的粘结，防止保温体系的脱落；通过采用轻质抹灰层作为硬泡聚氨酯的抗火层和保护层，当轻质抹灰层厚度大于等于40㎜时，可等效为A级结构体系，不受应用高度限制。
