膜结构的三大分类需要了解下
来源:http://www.sdcscp.com/ 发布时间:2022-07-30
膜结构建筑造型丰富多彩,千变万化,按照支承方式分为充气式膜结构、张拉膜结构和骨架支承膜结构。那么山东膜结构小编下面就跟您讲讲膜结构分类吧。
Membrane structure architecture has a variety of shapes, which can be divided into inflatable membrane structure, tensioned membrane structure and skeleton supported membrane structure according to the support mode. Now let's talk about the classification of membrane structures.
1.骨架式膜结构
1. Skeleton membrane structure
以钢构或是集成材构成的屋顶骨架,在其上方张拉膜材的构造形式,下部支撑结构安定性高,因屋顶造型比较单纯,开口部不易受限制,且经济效益高等特点,广泛适用于任何大,小规模的空间。
The roof skeleton, which is composed of steel structure or laminated materials, has a structural form of tensioning membrane materials above it, and the lower support structure has high stability. Because the roof shape is relatively simple, the opening is not easy to be restricted, and the economic benefits are high, it is widely applicable to any large and small-scale space.
2.张拉式膜结构
2. Tensioned membrane structure
以膜材、钢索及支柱构成,利用钢索与支柱在膜材中导入张力以达安定的形式。除了可实践具创意,创新且美观的造型外,也是能展现膜结构精神的构造形式.大型跨距空间也多采用以钢索与压缩材构成钢索网来支撑上部膜材的形式。因施工精度要求]高,结构性能强,且具丰富的表现力,所以造价略高于骨架式膜结构。
It is composed of membrane material, steel cable and strut, and uses steel cable and strut to introduce tension into the membrane material to achieve a stable form. In addition to creative, innovative and beautiful shapes, it is also a structural form that can show the spirit of membrane structure In large span space, steel cables and compressed materials are often used to form a steel cable network to support the upper membrane material. Due to high construction accuracy, strong structural performance and rich expressiveness, the cost is slightly higher than that of skeleton membrane structure.

3.充气式膜结构
3. Inflatable membrane structure
充气式膜结构是将膜材固定于屋顶结构周边,利用送风系统让室内气压上升到一定压力后,使屋顶内外产生压力差,以抵抗外力,因利用气压来支撑,及钢索作为辅助材,无需任何梁,柱支撑,可得更大的空间,施工快捷,经济效益高,但需维持进行24小时送风机运转,在持续运行及机器维护费用的成本上较高。
Inflatable membrane structure is to fix the membrane material around the roof structure, and use the air supply system to raise the indoor air pressure to a certain pressure, so that there is a pressure difference inside and outside the roof to resist external forces. Because the air pressure is used to support, and the steel cable is used as auxiliary material, without any beam and column support, it can get more space, fast construction, high economic efficiency, but it needs to maintain the 24-hour operation of the air supply fan, The cost of continuous operation and machine maintenance is high.
膜结构具有高安全性,符合国家规范和指南的膜结构在地震等水平荷载作用下能保持良好的稳定性。所以如果您有什么需求可以来我们网站http://www.sdcscp.com咨询。
