by Curtain wall is a maintenance wall structure or decorative structure outside the building, which is composed of panel and supporting structure system, has the specified bearing capacity, deformation capacity and adaptability to the displacement of the main structure, and does not share the role of the main structure.
1、 Differences between unit type curtain wall and component type curtain wall: (1) introduction to unit type curtain wall process: unit type installation is generally installed from bottom to top, which can be carried out simultaneously with civil engineering to save project progress.
(2) advantages and disadvantages of unit type glass curtain wall: advantages: fast on-site installation speed, short construction cycle, and can be constructed at the same time with civil engineering, especially suitable for high-rise buildings.
Disadvantages: the cost is higher than that of component type / it is more difficult to repair and replace.
(1) Introduction to the process of component curtain wall: the component installation is generally installed from top to bottom, and the construction can only be carried out after the civil construction is completed.
(2) advantages and disadvantages of component glass curtain wall: the installation sequence of component curtain wall should be completed before the civil structure; There are many on-site processing of component curtain wall; It is difficult to control the quality of component curtain wall.
2、 Contrast of curtain wall system (1) facade Flatness: the unit type is mainly processed in the factory, and the component type is mainly processed on the site, so the unit type has higher quality.
(2) Processing technology: the unit type is mainly processed in the factory, and the component type is mainly processed on the site, so the unit type has higher quality.
(3) Safety: most unit curtain walls can be installed indoors, and the safety factor is higher than that of frame curtain wall during operation.
(4) Installation quality: the component type needs to be installed in sequence after stacking materials on site.
The main workload of unit curtain wall component assembly is completed in the factory.
It only needs to be hoisted in place on site.
The installation is convenient and fast, and the project quality is guaranteed.
Water tightness and air tightness: the air tightness and water tightness of the unit type are better than that of the component type.
The unit type adopts the form of “drainage”.
When the floor is high, even if the external drainage is set on each floor, it can not avoid the hidden danger of water seepage caused by the accumulation of lower drainage.
The component type adopts the form of “blocking”.
Excellent design system and cost consideration are the favorite choice of most owners.
(5) Processing: the cost per square meter of component type is about 30% lower than that of unit type.
