轻钢结构住宅防腐蚀性能和节能降耗性能分析

发布时间:2015-8-31 9:12:48 浏览次数:743




防腐蚀性能

 
由于我国幅员辽阔,建筑材料需要满足各个地区、各种环境的要求。参照国家颁布的标准,对于高腐蚀性地区或特殊建筑物,镀锌量应不低于275g/㎡(双面)或镀铝锌150g/㎡(双面),并应满足现行国家或行业标准的规定。这一规定与澳洲的规定一致。
 
根据博思格钢铁澳洲研发中心的研究数据分析,重庆钢结构公司镀锌钢板和镀铝锌钢板作为结构使用与暴露在建筑外部,镀层消耗的速度会有很大的差别。即使在同一个建筑物内部,由于建筑各部分密封效果各不相同,造成大气腐蚀环境的不一致。由于镀铝锌镀层表面有铝和锌两种材料,铝更加容易被腐蚀,产生极其致密的AL2O3,这些铝的氧化物覆盖在钢板表层,更好地隔绝了镀层钢板与外界腐蚀环境的接触。因此镀铝锌层在室内环境中的预测寿命远远长于我们要求的结构寿命,可达到200年以上;即使在通风环境很不好的板材之间,预测寿命也能达到75年。
 
节能降耗性能
 
根据对轻钢结构住宅与传统住宅形式的节能降耗性能的比较,重庆钢结构公司能够明显地看出轻钢结构住宅的优势。技术经济指标主要是由建筑结构的导热系数、蓄热系数和每平方米每日能耗来评价。根据对轻钢结构住宅和传统的钢混结构住宅所作的对比实验,传统钢混结构住宅的导热系数在0.065~0.08W/m·k之间,轻钢结构住宅的导热系数在0.055~0.07之间,轻钢结构住宅的导热系数比传统钢混结构住宅降低了0.01W/m·k;传统钢混结构住宅的蓄热系数在0.95~1.10w/m.k之间,轻钢结构住宅的蓄热系数在1.30~1.40W/m·k之间,轻钢结构住宅的蓄热系数比传统钢混结构住宅降低了0.3W/m·k。
 

同时,由于轻钢结构体系的自重较轻且结构灵活,在满足结构强度要求的基础上,能够很好地集成各项保温节能技术,除了在墙的墙柱间填充玻璃纤维外,还采用在墙外侧再贴一层保温材料的“外墙外保温”做法,有效隔断了通过墙柱至外墙板的热桥;楼层之间楼面梁内填充玻璃纤维,减少通过楼层的热传递;所有内墙墙体的墙柱之间均填充玻璃纤维,减少户墙之间的热传递。



Corrosion resistance performance

Because our country is a large country, and building materials need to meet the requirements of all regions, all kinds of environment. Reference standards issued by the state, or special buildings for high corrosive region, galvanized quantity shall be not less than 275 g / ㎡ (double) or aluminum zinc plated 150 g / ㎡ (double), and shall meet the provisions of the existing national or industry standards. This provision in accordance with the provisions of the Australian.

According to Australian research and development center of bluescope steel research data analysis, chongqing steel structure company galvanized steel plate and aluminium zinc steel plate used as structure and exposed to the external architectural coating consumption can make a big difference. Even within the same building, because of the construction parts sealing effect each are not identical, atmospheric corrosion environment caused by inconsistent. Because there are aluminum and zinc aluminum plating zinc coating on the surface of the two materials, aluminum is more easy to corrode, extremely dense AL2O3, the aluminum oxide covered in steel plate surface, better cut off from the coated steel corrosion environment of contact with the outside world. Therefore aluminum zinc plating layer in the indoor environment prediction life far longer than we require that the structure of the life, can reach more than 200; Even in ventilation between the board that the environment is very bad, predict life can reach 75.

Saving energy and reducing consumption performance

According to the light steel structure housing and the performance of the traditional housing form of saving energy and reducing consumption, chongqing steel structure company can clearly see the advantages of light steel structure housing. Technical and economic indicators mainly by the coefficient of thermal conductivity of building structure, the heat storage coefficient and daily energy consumption per square meter to evaluate. According to the light steel structure housing and the traditional steel structure housing the contrast experiment, the traditional coefficient of thermal conductivity of the steel structure housing between 0.065 ~ 0.08 W/m k, the coefficient of thermal conductivity of light steel structure housing between 0.055 ~ 0.07, the coefficient of thermal conductivity of light steel structure housing than the traditional steel structure residential decreased 0.01 W/m, k; Traditional steel structure residential heat storage coefficient between 0.95 ~ 1.10 w/m.k, light steel structure residential heat storage coefficient between 1.30 ~ 1.40 w/m k, light steel structure housing than traditional heat storage coefficient of the steel structure housing decreased 0.3 w/m. k.

At the same time, because of the light steel structure system of the weight is light and flexible structure, on the basis of meet the requirements of structural strength, is able to integrate all kinds of heat preservation and heat insulation technology, in addition to the wall of the wall between column filled with glass fiber, also used to put a layer of heat preservation on the outside of the wall material of "exterior insulation" approach, the effective partition by wall column to the outer wall heat bridge; Fill glass fiber between floor floor beam, minimize heat transfer through the floor; All interior wall posts are filled between the glass fiber, reduce the heat transfer between the household wall.
