Bridge-cutoff cornice structure applied to ultra-low energy consumption building

Abstract

The invention provides a bridge-cutoff cornice structure applied to an ultra-low energy consumption building. The bridge-cutoff cornice structure comprises a reinforced concrete wall body, a reinforced concrete floor slab, a wall body cornice, a heat insulation material layer and a reinforced concrete construction layer, wherein a construction layer reverse cornice is arranged at the inner side ofthe reinforced concrete construction layer; and the construction layer reverse cornice and the wall body cornice are in lap joint and are isolated by an efficient heat insulation plate. The bridge-cutoff cornice structure has the advantages that the structure safety of an external construction layer of a sandwich heat insulation product can be effectively ensured; and the cornice structure can beprevented from generating a heat bridge effect. The bridge-cutoff cornice structure has the advantages that the heat insulation effect is good; the structure is simple; the connection is firm and reliable; and the construction is easy.

Description

Technical field [0001] The invention relates to the technical field of energy-saving building structures, in particular to a broken bridge eaves structure applied to ultra-low energy-consumption buildings. Background technique [0002] Building energy consumption accounts for about 30% of the total energy consumption of the whole society, and accounts for the largest proportion of the total energy consumption of the society. Therefore, building energy conservation has become the key to improving energy utilization and reducing pollution emissions. At this stage, ultra-low-energy buildings still adopt the traditional form of external thermal insulation. However, the practice of external thermal insulation has serious safety hazards in practical application projects. On the one hand, problems such as cracking and falling off of the thermal insulation layer are prone to occur. Insulation does not match the life of the main building, and needs to be replaced during the life of the bu...

Problems solved by technology

At this stage, ultra-low energy buildings still adopt the traditional form of external insulation. However, the practice of external insulation has very serious safety hazards in actual application projects. On the one hand, problems such as cracking and falling off of the insulation layer are prone to occur. Insulation does not match the life of the main body of the building and needs to be replaced during the life of the building

The solution to this kind of problem is to use a new type of sandwich insulation product to be used in ultra-low energy buildings. Since the sandwich insulation product has a certain thickness of reinforced concrete structural layer on the outside, it has a large dead weight. Considering the structural safety It is necessary to set overhanging eaves on the floors. However, the setting of overhanging eaves will inevitably produce thermal bridge effects, which will reduce the overall energy-saving effect of ultra-low energy consumption buildings
