Building cornice and curtain wall combined heat preservation structure and installation method

The invention relates to the technical field of building heat preservation construction, in particular to a building cornice and curtain wall combined heat preservation structure. A roof of the building is arranged above the curtain wall, the roof overhangs outwards to form a cornice, a thermal insulation wall is arranged on the roof above the curtain wall, the cornice is separated from a roof body through the thermal insulation wall, and the bottom of the thermal insulation wall is connected with the top of the curtain wall through an elastic sealing belt. According to the technical scheme, the heat preservation measure of the cornice part is directly abandoned, and then the heat preservation wall is used for connecting the heat preservation structure of the curtain wall and the roof. And the heat insulation construction difficulty is greatly simplified. 本发明涉及建筑保温施工技术领域，具体地涉及建筑挑檐与幕墙联合保温结构。幕墙的上方为建筑的屋顶，屋顶向外悬挑形成挑檐，幕墙上方的屋顶上设置保温墙，保温墙将挑檐与屋顶本体分隔开，保温墙的底部通过弹性的密封带与幕墙的顶部连接。通过以上技术方案，直接舍弃挑檐部分的保温措施，然后利用保温墙来衔接幕墙和屋顶的保温结构。大大
