屋面防水的问题有哪些?

 文章来源:http://www.jnldfs.com/ 发布时间:2022-05-23   

传统老别墅时间久了大多会出现屋面不保温,瓦脱落、渗漏等问题,而造成屋面防水工程渗漏的原因有工程设计、施工技术、管理维护等主要因素。
For a long time, most of the traditional old villas will have problems such as non thermal insulation of the roof, falling off of tiles and leakage. The leakage of roof waterproof engineering is caused by engineering design, construction technology, management and maintenance and other main factors.
一、工程设计的原因
1、 Reasons for engineering design
1.屋面防水维修缺乏整体设计,出现裂纹、防水层破坏等问题,相关维修单位只是针对漏水点的局部,做出一些治标不治本的补救措施,对裂缝、裂纹等进行了填堵、补漏,但这些表面工作未能从根本,上杜绝渗漏的问题的开展,问题严重者可能导致雨水从修补的防水层衔接处渗入。
1. The roof waterproof maintenance lacks the overall design, and there are problems such as cracks and damage to the waterproof layer. The relevant maintenance units only take some remedial measures for the local part of the water leakage point, and fill and repair the cracks and cracks. However, these surface works fail to fundamentally eliminate the leakage problem. If the problem is serious, it may lead to the infiltration of rainwater from the connection of the repaired waterproof layer.
2.原建筑物的整体刚度不够,各部位刚度差异大,漫长的沉降过程中造成屋面形变产生裂缝;屋面天沟采用了外天沟排水,构造上的特殊性造成--旦受堵则楼面会产生大量积水导致建筑的渗漏问题。
2. The overall stiffness of the original building is not enough, and the stiffness difference of each part is large, resulting in roof deformation and cracks in the long settlement process; The roof gutter adopts external gutter drainage, which is caused by the particularity of structure - once blocked, a large amount of ponding will be generated on the floor, resulting in the leakage of the building.
二、材料品质的原因
2、 Reasons for material quality
有些防水材料的延伸率、耐热度、粘结力、、材料之间的相容性等性能不一,造成有些防水卷材已经出现空鼓、起皮、开裂。
Some waterproof materials have different properties such as elongation, heat resistance, adhesion, and compatibility between materials, resulting in hollowing, peeling and cracking of some waterproof coiled materials.
三、施工技术的原因
3、 Reasons for construction technology
通过总结上述渗漏问题的原因,施工团队是否是关键,首先体现在施工队伍的非**化。施工人员没有过硬的操作技术,甚至一些人员没有经过培训直接上岗或是无证上岗;一些经验充足的施工人员完全依靠自身的施工经验,不严格按照施工规范、设计图纸,进行随意施工处理。如要求作业人员不得穿着硬底鞋子,易破坏防水层,墙面防水高度未严格按照设计要求,再者防水层搭接长度不足、倒贴,防水材料涂层数量不足,导致厚度不足引发后期一系列防水过程中出现的问题。
By summarizing the causes of the above leakage problems, whether the construction team is the key is first reflected in the non * * of the construction team. The construction personnel do not have excellent operation skills, and even some personnel go to work directly without training or without certificates; Some construction personnel do not fully rely on their own construction experience and do not strictly deal with the construction according to the design drawings. If the operators are required not to wear hard soled shoes, it is easy to damage the waterproof layer. The waterproof height of the wall is not in strict accordance with the design requirements. In addition, the overlapping length of the waterproof layer is insufficient, and the number of waterproof material coatings is insufficient, resulting in insufficient thickness, which leads to a series of problems in the later waterproof process.
