Abstract

The invention discloses a semi-precast lightweight white concrete curtain wall, which is characterized in that the curtain wall is sandwich sandwich structure, and the curtain wall comprises a left side surface template, a right side surface template and a middle sandwich layer, wherein the left side surface template and the right side surface template are lightweight white concrete molding members, and the middle sandwich layer is a self-compacting concrete layer. A light white concrete component and a weight portion thereof are as follow: (img file= 'DDA0001745311660000011. TIF' wi= '700' he= '534'/) The beneficial effects of the present invention are: The invention provides a concrete curtain wall form integrating decoration, heat preservation and structure, which is neat and beautiful,the number of splicing joints is small and the weight is light.

Description

technical field [0001] The invention belongs to the field of curtain wall prefabrication, and in particular relates to a semi-prefabricated lightweight white concrete curtain wall and a construction method thereof. The invention is applicable to construction fields such as non-high-rise building enclosures, low-rise buildings requiring decoration inside and outside, and landscape corridors. . Background technique [0002] With the development of social economy and the improvement of urban appearance, buildings are becoming more and more high-end and multi-functional. An important part of the building structure system must also develop in the direction of high-tech, functional integration, and prefabricated industrialization, so as to adapt to people's increasing awareness of environmental protection and energy conservation and meet the market development requirements of building industrialization. [0003] While prefabricated concrete components are being developed vigorous...
