  • 为什么轻质隔墙板会出现裂缝或者是脱落
  • 本站编辑:杭州久泰建材有限公司发布日期:2019-11-13 19:36 浏览次数:
 轻质隔墙板出现裂缝或者是脱落现象的原因:轻质隔墙板强度低,两块板缝共设1个钢板卡,部分板角破损,造成板端与结构墙板开裂;其次是部分轻质隔墙板的混凝土,未达到设计强度要求,轻骨料混凝土抗压强度值小于7.5MPa。
 
  轻质隔墙板长向边未设企口,竖向接缝只设一道100mm宽的聚脂无纺布连接,未按88J2-7中要求的在接缝加强后,对整面轻质隔墙板再做一道聚脂无纺布加强面层。另外,门窗洞口异形板是由标准轻质隔墙板切割而成的,在门口端板与竖向板支座处粘结剂不密实,加之轻质隔墙板未做满粘的聚脂无纺布加强。
 
  几年来,轻质隔墙板施工质量问题,己成为工程质量问题的焦点。针对这个问题,生产厂家应逐渐加深对轻质隔墙板设计、生产管理、安装施工全过程的理解,并且能够对轻质隔墙板在住宅建筑工程中的合理使用起到积极作用。

The Light Partition Board appears the crack or is the reason which falls off the phenomenon: The Light Partition Board strength is low, two plate joints altogether sets a steel plate card, partial plate angle is damaged, causes the board end and the Structure Wall Board to crack; next is the partial light partition board concrete, the compressive strength of lightweight aggregate concrete is less than 7.5 MPA. Light Partition Board is not set on the long side, vertical joint is only set on a 100mm wide polyester non-woven fabric connection, not according to 88J2-7 requirements in the joint after strengthening, the whole light partition board to do a polyester non-woven fabric reinforced surface. In addition, the door and window hole shaped board is cut by the standard light quality partition board, in the door end board and vertical board support at the binder is not dense, in addition to light quality partition board not do full adhesion of polyester non-woven fabric reinforcement. In recent years, the construction quality of light partition board has become the focus of engineering quality problems. In view of this problem, manufacturers should gradually deepen the understanding of the whole process of design, production management, installation and construction of light partition board, and play a positive role in the rational use of light partition board in residential construction.
