膜結構在設計時要注意什么?
眾所周知,膜結構在設計時要注意, 結構與建筑的完全結合,找形來**系統(tǒng)的靜態(tài)平衡,應力剖析非線性及大變位,膜結構找形的互反雙曲面,適宜各不同區(qū)域的風雪荷載。那么膜結構在設計時的注意事項有哪些?下面膜結構廠家小編來簡單介紹一下:
As is well known, in the design of membrane structures, attention should be paid to the complete integration of the structure and the building, finding the static balance of the system based on the shape, analyzing the nonlinear and large displacement of the stress, and finding the reciprocal hyperbolic surface of the membrane structure shape, which is suitable for wind and snow loads in different regions. What are the considerations for designing membrane structures? Let's briefly introduce the structure of the facial mask:
1、透光性: 半透明是膜結構有顯著的特征,與其它材料比較,無論是在漂亮上或是在操作上,都有顯著的優(yōu)越性,散射光線,眩光,能將光線廣泛地漫射到其內部空間,材料內部涂層具有較高的反射率,能在夜間堅持室內的照明效果,夜間逆光照射下外表發(fā)光,天然照明,節(jié)省動力。
1. Translucent: Translucent is a significant feature of film structure, which has significant advantages over other materials in terms of beauty and operation. It scatters light, eliminates glare, and can widely diffuse light into its internal space. The internal coating of the material has high reflectivity, which can maintain indoor lighting effect at night. Under backlighting at night, the surface emits light, natural lighting, and saves power.
2、動力節(jié)省:膜結構外形漂亮,一起又為人們發(fā)明了天然光采光的環(huán)境,與玻璃材料比較,它大大削減了熱量的傳遞,與不透光的材料比較,削減了室內照明用電,運用膜結構對動力問題的影響:在熱帶區(qū)域,削減了空調制冷用電量,在寒冷區(qū)域,增加了室內取暖設備的用電。
2. Power saving: The membrane structure has a beautiful appearance and has invented a natural lighting environment for people. Compared with glass materials, it greatly reduces heat transfer, and compared with opaque materials, it reduces indoor lighting electricity consumption. The impact of membrane structure on power problems: in tropical areas, it reduces air conditioning cooling electricity consumption, and in cold areas, it increases indoor heating equipment electricity consumption.
3、聲學效果: 建筑聲學主要是A、 排除外界噪聲 B、吸收室內回音 膜結構的膜材料,能讓室內0-60HZ的低頻率噪音透過,較大面積和較高特別需求的,可以選用專門的內膜材料,吸收噪聲,當然,膜材料對外部噪音削減隔絕才能是有限的,因此當對外部隔噪聲要求較高時,膜材料可能是不適宜的。
3. Acoustic effect: Building acoustics mainly involves A. eliminating external noise B. absorbing the membrane material of indoor echo membrane structure, which can allow low-frequency noise from 0-60Hz to pass through. For larger areas and higher special requirements, specialized membrane materials can be selected to absorb noise. Of course, membrane materials have limited ability to reduce and isolate external noise. Therefore, when high requirements are placed on external noise isolation, membrane materials may not be suitable.
4、防火 :膜材料完全滿足防火規(guī)范的要求,因此在高度和間隙度允許下,膜結構適宜于任何一種建筑,一般自動救活系統(tǒng)對膜材料是適宜的,防火設計時應從全體考慮。
4. Fireproof: The membrane material fully meets the requirements of fire safety regulations. Therefore, under the allowable height and clearance, the membrane structure is suitable for any type of building. Generally, automatic rescue systems are suitable for membrane materials, and fire protection design should consider all aspects.
