LNG storage tank dome structure and construction method
The invention discloses an LNG storage tank dome structure and a construction method. The LNG storage tank dome structure comprises a concrete surface layer, concrete beams, an inner film upper plate, an inner film lower plate, side plates and heat preservation materials. The concrete beams comprise ring beams and longitudinal beams, and the ring beams and the longitudinal beams intersect with each other to form annular abreast cavity areas; the inner film lower plate and the inner film upper plate are correspondingly located at the bottoms and the tops of the cavity areas, the cavity areas are filled with the heat preservation materials, the side plates are arranged between the heat preservation materials and the inner walls of the cavity areas, the concrete surface layer and the concrete beams are of an integrated frame structure, and the concrete surface layer covers the top face and the bottom face of the whole dome. The cast-in-place concrete beam and a prefabricated concrete hollow inner formwork are combined, and different from a conventional beam-free plate shell cast-in-place concrete dome structure, the LNG storage tank dome structure has the advantages of being stable in structure, good in heat preservation performance, short in engineering period and the like.
本发明公开了一种LNG储罐穹顶结构及建造方法，穹顶结构包括混凝土表层、混凝土梁、内膜上板、内膜下板、侧板及保温材料，混凝土梁包括环梁和纵梁，环梁和纵梁相互交叉形成环形并排的空腔区域，内膜下板和内膜上板分别位于空腔区域的底部和顶部，空腔区域内填装所述保温材料，保温材料和空腔区域内壁之间设有侧板，混凝土表层和混凝土梁为一体式框架结构，且混凝土表层覆盖整个穹顶的顶面和底面。其结构现浇混凝土梁与预制装配混凝土空心内模板组合，不同于常规无梁板壳现浇混凝土穹顶结构，具有结构稳定、保温性能好、工程周期短等优点。
