Description

Decorative insulation system under the eaves of antique buildings

technical field

The invention relates to a heat preservation system for an antique building, in particular to a decorative heat preservation technology system under the eaves of an antique building, which belongs to the field of construction.

Background technique

In recent years, in the protective construction of some historical and cultural cities or historic blocks, in order to obtain the original appearance and appearance of ancient buildings, a large number of antique public buildings using cast-in-place reinforced concrete technology have been built. With the continuous development of building energy conservation and emission reduction in my country, the requirements for energy conservation of public buildings have been further clarified, and the limitations of modern antique public buildings in terms of thermal insulation and energy conservation have been revealed. Due to the many wooden decorations such as bucket arches, squares, and wall panels under the eaves of the antique buildings, which are fine and cumbersome, the use of reinforced concrete structures solves the modeling problem, but it is difficult to achieve the insulation of the antique components, resulting in the insulation layer of the modern antique building envelope. Continuous, the proportion of thermal bridges is too large, which leads to problems such as excessive energy consumption of antique buildings and the impact of indoor comfort. Therefore, the decoration and thermal insulation technology of the structure under the eaves of the antique building needs to be improved.

Contents of the invention

The decorative insulation of the bucket arches under the eaves of the antique building is a weak link in the thermal insulation of the enclosure structure. Due to the complex shape and thinness of the components, it is difficult to arrange a thick thermal insulation layer, so it is difficult to achieve the thermal insulation effect required by the energy-saving code. In order to solve the problem that the heat preservation of decorative components under the eaves of modern antique buildings is difficult to achieve, and there are too many thermal bridges, to realize that the antique buildings meet the current energy-saving standards for buildings of corresponding grades, and to achieve the goal of energy saving and emission reduction of antique buildings, the present invention proposes an antique building under the eaves Decorative insulation system.

The technical scheme adopted in the present invention is the decoration and heat preservation system under the eaves of an imitation building. constitute.

The light steel keel skeleton is made of cold-formed thin-walled steel. The light steel keel for construction should meet the requirements of the national standard GB2518-88. The galvanized steel plate should be cold-pressed and applied to building components. The cross-sectional shape of the light steel keel is mainly divided into There are two types, U-shaped and C-shaped.
