XPS板在外墙外保温工程中应用日益增多,但现有XPS板类外墙外保温技术存在系统强度和耐久性不足,使用寿命较短,XPS钢丝网架板现浇混凝土外保温施工复杂,墙内外伸钢筋变形使抹灰层下坠、开裂,斜插钢丝易形成热桥等问题。因此,需要改进现有XPS板外保温技术。钢网架XPS板外墙外保温系统以其优良的综合性能,较好地解决了上述问题。本文对钢网架XPS板外墙外保温系统的技术原理和构造进行了介绍,对其防火性能进行了分析,并对其施工工艺作了阐述。
XPS board is widely used in exterior insulation and insulation engineering. However, the existing XPS board exterior insulation and insulation technology has the problems of insufficient system strength and durability and short service life. The construction of XPS steel mesh in-situ concrete exterior insulation is complex, and the wall Stretching both inside and outside the extension of the plaster layer so that the fall, cracking, obliquely inserted into the wire easy to form a thermal bridge and other issues. Therefore, there is a need to improve the existing XPS board thermal insulation technology. Steel frame XPS board exterior insulation system with its excellent overall performance, a better solution to the above problems. This paper introduces the technical principle and structure of XPS board exterior insulation system of steel truss, analyzes its fireproof performance, and elaborates its construction technology.
