1、济南防水http://www.tianyujian.com/分析目前的框架结构住宅工程中填充墙,基本上为非承重的灰砂砖或小型砌块。灰砂砖和小型砌块在运输与施工过程中容易产生破损,缺棱掉角等缺陷。若在施工中使用了受破损 或由于设备管暗装的需要对已砌外墙进行凿打,人为地造成外墙砌体破损,也较容易在外墙 砌体形成渗水处;温差引致混凝土结构梁柱与填充墙结合处产生开裂。
Jinan waterproof analyze the current framework housing project infilled, substantially non-load-bearing sand-lime bricks or small blocks. Sand-lime brick and small block in the transport and construction process prone to breakage,missing edge off angle defects. When used in the construction of the pipe due to equipment that is damaged or concealed need to build external walls have been caulked, artificially created damaged masonry facades, but also relatively easy to form a water seepage at the masonry facades; temperature difference caused by concrete structural beams columns and infill walls junction cracking.
2、济南防水介绍工人在砌体施工中未严格按施工规范操作,砌筑砂浆不饱满,特别是竖缝砂浆。此外,砂浆的强度不达标或干砖上墙,使砂浆中的水份被砖吸收,从而造成砂浆强度偏低,导 致砖和砂浆分离,砌体整体刚度下降,产生墙体裂缝。外墙抹灰层一次性打底太厚或为保证全高垂直度而使局部打底偏厚,又未采取适当 加强措施而产生裂缝;墙体层表面太光滑,结合不良;外墙大面积打底而基层未设分格线, 产生不规则收缩裂缝。
Jinan waterproof introduce workers not in strict accordance with construction norms operating in masonry construction, masonry mortar is not full, especially vertical mortar joints. In addition, the strength of non-compliance or mortar dry brick wall, mortar brick in the water is absorbed, resulting in low strength of mortar, brick and mortar lead to separation, the overall stiffness of masonry fall, resulting in cracks in the wall. External plastering layer is too thick or one-time rendering to ensure the full high vertical partial thickness leaving the local base, they did not take appropriate measures to strengthen and cracks; too smooth surface of the wall layer, combined with bad; the external walls of a large area of play The grass does not have a bottom ruled lines, resulting in irregular shrinkage cracks.
3、济南防水http://www.tianyujian.com/谈到饰面砖铺贴空鼓或铺贴砂浆不饱满,面砖与砂浆间空隙部分易形成贮水容器;面砖 勾缝不密实或勾缝龟裂,密缝勾缝遗漏都是使雨水从表面渗入,造成积水,从而引起渗漏;窗台、遮阳板和雨篷等水平构件的表层施工中未找坡度,甚至倒坡,造成倒返水或积水,也容易造成外墙面渗水。
Speaking Jinan waterproof decorative brick paving or paving mortar hollowing is not full, the gap between the brick and mortar part is easy to form water containers; brick pointing is not dense or pointing cracks, pointing omissions are
tightly sewn so that rain water from penetrate the surface, resulting in stagnant water, causing leakage; surface construction windowsill, sun visors and awnings and other horizontal member not find the slope, even down slope, causing pour rakeback or water, it is likely to cause the outer wall of water seepage.
