建筑翻新的原因
Reasons for Re-roofing
1.结构老化 Ageing of structure
Roofing
主结构老化 结构加固 Ageing of main structure reinforcement of main structure 维护结构老化 更换维护结构或改造 Ageing of building enclosure replace enclosure or re-roofing 重新装修或作局部改造 re-decoration or local change 粮仓改为宿舍,厂房改为艺术馆或博物馆等等 grain warehouse changed to dormitory; plant changed to art gallery or museum 屋面渗漏 roof leakage 节能改造 renovation for energy efficiency 环保(屋面绿化等) environment friendly (green roof)

翻新屋面的特点 Features of Re-roofing Projects
1.层次不明确 Unclear built-ups 2.屋面较脏乱 Messy roof 3.屋面存在较多设备及穿出构件,造成有些部位施工空间较小,收口困难 Many equipment and penetrations on roof, difficult for installation and termination 4.不可预测的问题较多 A lot potential problems & risks
2.使用功能变更 Function change 例如: Example:
3.不能满足使用功能 Function fails
上述几种情况中除了结构加固外都可能用到西卡渗耐防水系统. Sika Sarnafil waterproof system can be applied in the above re-roofing projects except structure reinforcement.

The aluminum roof base is similar to steel roof. Wood deck roof is taken as Individual case and can be similar to steel roof.

屋面防水施工不影响建筑内部的使用功能 No influence to inner function of building 几乎无噪音,振动 Almost no noise or vibration 无刺鼻气味 No irritating smell 施工周期比较短,使用寿命长 Short installation period; long use life 每天可完成150~220sqm(包含进场和清场),屋面面积越大单位时间完成的面积越大;西卡 渗耐防水系统有超过25年的寿命(美国承包商协会96年的报告) 150~220sqm per day (including entrance and clear up); bigger area in unit time for bigger roof area; Sika Sarnafil waterproof system has a record of over 25 year life (reported in 1996 by U.S.A. Contractor Association) 不破坏原有结构 No damage to original structure 使用固定件或胶粘剂固定卷材于维护结构上或屋面表面. Fix membrane on enclosure or roof surface with fasteners and adhesives 更环保 More environment friendly 现场应用热风焊接,非明火,产生的污染少. Hot-air welding onsite; no open fire; less pollution 造成的附加荷载小 Less additional load 以机械固定系统为例,假设使用1.5厚卷材,0.3厚PE 膜,40厚XPS保温板,则屋面附加荷载约 在0.035KN左右. Take MF system for example, the additional load is about 0.035KN to roof if using 1.5mm membrane, 0.3mm PE film and 40mm XPS insulation board 后期使用中的破坏点容易修复 Easy repair in case of damage

翻新屋面要求Considerations for Re-roofing Projects
1.要体现屋面的整体效应; Roof function 满足结构承重,防水,保温隔热,绿化,节能及环保等多种功能 structure load, waterproof, insulation, green roof, energy efficiency, environment friendly, etc. 2.各个构造层次要相互匹配; Built-up match 各种相接触的材料互相不产生反应(包括物理的和化学的) Materials that contact should be compatible (physically & chemically) 3.合理的工程造价与合理的使用年限相结合; Reasonable investment brings a good use life 4.应符合可持续发展需要; Continuous development 不使用淘汰或落后的不符合环保要求的材料 Don’t use obsolescent or environment un-friendly materials 使用先进的施工工艺 Use advanced installation process 5.翻新方案设计与深化设计之间的关系. Design 由设计院进行方案初步设计,确定防水等级,技术原则等相关要求; The design institute will define the waterproof grade, technical principles and other requirements. 由专业防水公司进行深化设计,确定防水材料与施工工艺并绘制节点构造大样. The waterproof company will define waterproof materials, installation process and work out drawings.

信息收集 Information Collection
相对于新屋面来说,旧屋面的防水处理具有更大的复杂性,存在更多的不确 定性及风险.全面的信息收集可以让我们提早找到问题并解决问题,尽量避 开风险. Waterproof projects for old roofs are more complex, uncertain and risky compared with new roofs. Complete information collection help us find and solve problems to avoid risks as early as possible. 1.混凝土基层屋面 Concrete roof base 原有的建筑图纸 original roof drawings 建筑的使用功能 roof function 建筑投入使用的时间 building age 实际的屋面构造层次 actual roof built-ups 混凝土强度 concrete strength 沥青焦油含量 content of bitumen and tar 渗漏情况 leakage conditions 各节点的状况及数量 detail quantity and description 业主的其他要求 Other requirements of the owner 其他 Other information
