挤塑板外墙外保温系统裂缝操控准则
来源:/ 日期:2018-10-23 发布人:

抵挡五种天然破坏力(热应力、风、水、火、地震力),采纳答应变形、限制变形、诱导变形的技术道路开释形变应力,是外墙外保温安全性的请求。在外墙外保温节能工程施工中,对外墙外保温系统裂缝的操控,应遵从以下准则:

To withstand the five natural destructive forces (thermal stress, wind, water, fire, earthquake force) and to adopt the technical road that permits deion, restricts deion and induces deion to release the deion stress is the requirement of the safety of exterior wall insulation. In the construction of the external thermal insulation and energy-saving project, the cracks in the external thermal insulation system of the external wall should be controlled according to the following criteria:

(1)逐层突变、柔性开释应力。

(1) layer by layer mutation, flexible release stress.

(2)保温系统不要运用质量差的水泥浆作为表面的找平和保护层的资料,一般选用聚合物水泥胶浆。

(2) Insulation system do not use poor quality cement slurry as a surface leveling and protective layer of inion, the general choice of polymer cement mortar.

(3)没有空腔或者空腔空间较小可以提高系统的全体稳定性,一般选用点粘法。

(3) No cavity or small cavity space can improve the overall stability of the system. Point sticking method is generally used.

(4)防护层的抗裂问题是操控裂缝的主要矛盾,一般选用聚合物水泥胶浆具有较好的抗裂功能。

(4) The anti-crack problem of protective layer is the main contradiction of crack control. The polymer cement mortar is generally used to have better anti-crack function.

(5)为验证外保温系统的稳定性及运用寿命,有条件时应进行大型耐候性实验。

(5) In order to verify the stability and service life of the external insulation system, large-scale weatherability tests should be carried out when conditions permit.

(6)应尽量挑选涂料外饰面外保温系统。

(6) we should try to choose the exterior insulation system for coating exterior.

(7)应充分考虑各层资料的相容性及匹配性。施工推广样板先行,并凭借现场拉拔实验以断定XPS板粘锚牢固。

(7) full consideration should be given to the compatibility and matching of all layers of data. The construction and extension of the model is first, and the XPS board is firmly anchored by field drawing experiments.
