外墙出现渗漏的情况抹面砂浆可以解决吗?

来源:https://www.jnfhjc.com 日期:2019-05-06 发布人:admin

首先,我们要找到渗水的缘由,普通外墙呈现渗漏的缘由不外乎以下几点:
  First of all, we need to find the reasons for the seepage. The reasons for the seepage of ordinary exterior walls are as follows:
  1、外墙涂料老化,起皮;
  1. Exterior wall coating aging and peeling;2、外墙抹面砂浆开裂、零落等;
  2. Cracking and scattering of exterior wall plastering mortar;3、外墙瓷砖勾缝开裂、零落等;
  3. Cracking and scattering of the hook seam of external wall tiles;4、屋面女儿墙根或屋面防水呈现失效;
  4. Roof parapet roof or roof waterproofing is invalid.
  5、窗户四周呈现裂痕现象……这些现象构成外墙迎水面防水失效,这是外墙渗漏的直接缘由。
  5. Cracks appear around windows... These phenomena constitute the failure of waterproofing on the water face of the external wall, which is the direct cause of the leakage of the external wall.
  找准渗漏的缘由,对症下药就可以了:一、确保找平层的施工质量1、找平层抹灰前的工作:应留意砌体批灰前表面的湿润,喷洒水充分,砌体部分与混凝土部分交接处的外墙面在抹灰前要用200㎜宽16#钢丝网片掩盖并加以固定,以抵御因不同防水堵漏材料的收缩系数不同而惹起的开裂。对混凝土墙面的浮浆、残留的模板木屑,显露的钢筋、铁丝一定要清算干净,以利抹灰砂浆与基层粘结坚固。
  To find out the cause of leakage, we should take appropriate measures: 1. Ensure the construction quality of leveling layer 1. Work before plastering leveling layer 1. Pay attention to the wetness of the front surface of masonry before plastering, spraying water adequately, and cover and fix the outer wall at the junction of masonry part and concrete part with 200_16_wide wire mesh before plastering, so as to resist the shrinkage coefficient of different waterproof materials. Cracks caused by differences. The exposed steel bars and wires must be cleaned up for the floating slurry of concrete wall and the residual template sawdust, so as to make the plastering mortar bond with the base firmly.

  2、找平层抹灰时应留意:
  2. When plastering the leveling layer, attention should be paid to:
  ⑴砂浆应严厉按配比中止,严厉计量,控制水灰比,严禁施工过程中随意掺水;⑵对抹灰砂浆应分层抹灰,特别是高层建筑,局部外墙抹灰较厚,这就需求中止分层批灰,每层抹灰厚度不应超越2㎝,如厚渡过大,在分层处应设钢丝网;⑶批灰砂浆可用聚合物防水砂浆;(1) Mortar should be severely discontinued according to mix ratio, metered strictly, water cement ratio controlled, and free mixing of water during construction is strictly prohibited; (2) Layered plastering should be applied to plastering mortar, especially in high-rise buildings, where the local exterior wall is thicker, which requires the discontinuation of layered batch of mortar, and the thickness of each layer should not exceed 2_, if the thickness of plastering is too large, steel wire mesh should be set at the layers; (3) Polymer waterproof mortar can be used for batch of mortar;⑷外墙抹灰脚手架拉接筋等,应切割后,喇叭口抹实压平,定浆后,可用铁抹子切成反搓,然后再刷一道素水泥浆。
  (5) External wall plastering scaffolding tension reinforcement, etc., should be cut, trumpet mouth plastering flat, after slurry, can be used to cut iron plaster into reverse rubbing, and then brush a plain cement slurry.
