Large-curvature large-span multilayer ETFE pneumatic membrane structure and construction method thereof
The invention discloses a large-curvature large-span multi-layer ETFE pneumatic membrane structure and a construction method thereof. The construction method comprises the steps that a roof is spliced, an arched beam structure is installed in a sliding and in-place mode, and the arched beam structure is welded, coated, reinforced and stabilized; the ETFE film structure is optimized, shape finding analysis, load analysis and cutting analysis are carried out, an intelligent inflation system is installed, and the ETFE film structure is connected with the arched beam. Roof splicing and sliding in-place installation of an arched girder structure are adopted, roof construction loads are reduced, an original concrete structure is protected, steel structure deformation is prevented, an ETFE film structure is optimized, shape finding analysis, load analysis and cutting analysis are carried out, an air pillow structure is formed by multiple layers of inflatable blades, certain pressure exists in the blades through inflation, so that external loads are resisted, and the service life of the blades is prolonged. On the other hand, the air cavity formed by the multi-layer film structure can increase the thermal resistance of the film layer, and the thermal insulation performance of the film layer is improved.
本发明公开了一种大曲率大跨度多层ETFE充气膜结构结构及其施工方法，屋面拼装、滑移就位安装拱梁结构，对其进行焊接、涂料，加固稳定；优化ETFE膜结构，进行找形分析、载荷分析、裁剪分析，安装智能充气系统，ETFE膜结构与拱梁连接。本发明采用屋面拼装、滑移就位安装拱梁结构，减少屋面施工荷载、保护原混凝土结构、防止钢结构变形，优化ETFE膜结构，进行找形分析、载荷分析、裁剪分析，多层充气叶片形成的气枕结构，通过充气使得叶片内部具有一定的压力，从而抵抗外界荷载，如风、雨、雪等而引起的立面变形，另一方面，多层膜结构所形成的空气腔可以增加其热阻，提高膜层的保温性能。
