防止外墙抹面砂浆层裂缝的预防措施是什么?

来源: 日期:2019-12-05 发布人:admin

  1、图纸设计选择密度18 - 22公斤/立方米保温板,通过众议院批准的材料和合格的检查机构,在保温材料质量密度现场测量方式验收,定期或在建设的过程中聚苯板密度测量抽查,防止施工单位在施工过程中以次充好的行为。

  1. For the design of drawings, 18-22kg / m3 insulation board shall be selected, which shall be accepted by the material and qualified inspection organization approved by the house of representatives in the field measurement of the quality and density of insulation materials, and checked by the density measurement of polystyrene board regularly or in the process of construction, so as to prevent the construction unit's behavior of shoddy in the process of construction.
  2. 保温材料由系统材料供应商配套提供,充分发挥粘结剂、保温板、耐碱玻纤网布、抹灰砂浆的整体效果。
  2. The thermal insulation materials shall be provided by the system material supplier to give full play to the overall effect of binder, thermal insulation board, alkali resistant glass fiber mesh and plastering mortar.
  3,尽量选择正规施工企业的综合实力,开发人员可以为材料支付预付款,建设单位必须事先定制的保温板,以确保保温板保温施工前有足够的老化时间,防止保温板在墙上继续萎缩。

  3. Try to choose the comprehensive strength of formal construction enterprises. Developers can pay in advance for materials. The construction unit must customize the insulation board in advance to ensure that the insulation board has enough aging time before construction and prevent the insulation board from shrinking on the wall.
  4、将聚苯板糊固定好后,糊的强度要符合要求,及时做好抹灰层,避免因温度过高而导致板面面糊曝光时间过长。
  4. After the polystyrene board paste is fixed, the paste strength shall meet the requirements, and the plastering layer shall be made in time to avoid too long exposure time of the board paste due to too high temperature.
  5. 基础与粘结剂之间的抗拉结合强度不得低于0.3mpa,粘结界面的脱粘面积不得大于50%。
  5. The tensile bond strength between the foundation and the binder shall not be less than 0.3MPa, and the debonding area of the bonding interface shall not be greater than 50%.
  6. 所使用的外墙保温系统材料应符合相关行业标准的要求,如《膨胀聚苯板薄抹灰外墙保温系统》(jg149 -2003)和《外墙保温工程技术规程》(JGJ 144-2004)。
  6. The materials used for external wall thermal insulation system shall meet the requirements of relevant industry standards, such as expanded polystyrene board thin plastering external wall thermal insulation system (jg149-2003) and technical specification for external wall thermal insulation engineering (JGJ 144-2004).
