轻钢结构住宅防防潮性能、隔声性能和节能火性能分析

发布时间:2015-8-31 9:12:49 浏览次数:780



防潮性能

 
在轻钢住宅的标准配置中,整个墙体的外围使用单向呼吸纸对整个墙体进行防潮密封。这种密封可以在隔绝室外潮气进入室内的同时,避免室外大气中的有害物质腐蚀金属材料,也可以排除室内的潮气。而整个墙体用到的石膏板也成为可以呼吸的墙体。呼吸纸和防潮膜可以保证金属产品在密封而干燥的空间有更加长久的寿命,也可以让室内的空气更加干爽。

防火性能
 
暴露的轻钢结构在550℃的高温下,一般在15分钟左右就会丧失承重能力而垮塌。重庆钢结构公司但通过油漆、复合或加厚围护材料,在围护结构上运用一些防火性能比较好的材料,可以确保整个住宅的防火性能达到规范的要求。
 
从目前轻钢结构别墅的实践情况来看,经过特殊防火处理的轻钢结构住宅能够满足防火规范的要求。在国家固定灭火系统和耐火构件质量监测中心的实件检测中,博思格钢铁配备双面双层石膏板的墙体耐火实验,承重墙体可以达到1.22小时的耐火极限。
 
隔声性能
 
轻钢结构住宅由于受力构件自重较轻,且中间基本上为中空结构,很容易形成“鼓膜”效应,因此撞击隔音效果很差。为了满足空气隔音和撞击隔音的综合要求,在轻钢结构住宅中,可以采用内外墙及楼盖搁栅间填充玻璃棉,重庆钢结构公司来有效阻止通过空气传播的音频部分。试验表明,填充玻璃棉能够使结构的空气隔音效果得到进一步的提高,达到50dB以上,在进行围护结构处理之前,就能够达到居住的要求。
 

Moistureproof performance

In the standard configuration of light steel housing, the periphery of the entire wall using one-way breathing paper to seal the entire wall. The seal can be cut off in the moisture enter indoor and outdoor, avoid harmful material outdoor atmospheric corrosion of metal material, also can eliminate indoor humidity. And the whole wall use plasterboard wall also be able to breathe. Breathing and moistureproof film paper can guarantee in a sealed metal products and dry space has more long life, also can make indoor air more dry.

Fireproof performance

Exposure of the light steel structure under the high temperature of 550 ℃, generally in 15 minutes or so will lose bearing capacity and collapse. Chongqing steel structure company but through paint, composite or thickening palisade materials, using some fire on palisade structure performance is good material, can ensure the whole residential fire performance to achieve the requirement of the specification.

From the perspective of the practice of the light steel structure villa, fire prevention with special light steel structure housing can meet the requirements of the code for fire protection. In the national fixed fire extinguishing systems and fire-resistant components of quality monitoring center of real tests, bluescope steel equipped with double double plasterboard wall refractory experiment, the fire resistance of bearing wallboard can reach 1.22 hours.

Sound insulation performance

Light steel structure housing the slabs due to dead weight is lighter, and basically to the hollow structure, it is easy to form the tympanic membrane effect, so the impact sound insulation effect is very poor. In order to meet the sound insulation and air impact sound insulation of the comprehensive requirements, in the light steel structure housing, can use external walls and floor joists fill glass wool, chongqing steel structure company to effectively prevent the audio part of spreads through the air. Tests show that fill the glass wool can make the structure of the air sound insulation effect is increased further, amounting to more than 50 db before palisade structure processing, will be able to meet the needs of living.
