Small block assembly type subway station structure based on glue splicing theory
The invention discloses a small block assembly type subway station structure based on the glue splicing theory, a subway station is composed of a plurality of first splicing rings and second splicing rings which are alternately arranged, and the first splicing rings and the second splicing rings are tensioned and fixed by penetrating longitudinal prestressing tendons into the first splicing rings and the second splicing rings. The first splicing ring and the second splicing ring are formed by splicing a plurality of prefabricated parts, prefabricated blocks on the first splicing ring and the second splicing ring are arranged in a staggered joint mode, joints between the prefabricated blocks are connected through the glue splicing technology, and after connection, transverse prestressing tendons and vertical prestressing tendons penetrate into the joints to be tensioned and fixed. The size and the weight of each precast block are reduced, and transportation and on-site construction are facilitated; the positions, where stress concentration is prone to being generated, of the joints of the walls, the columns and the plates are all made into prefabricated parts, and the stress performance of weak structure joints can be improved; joints are connected through the glue splicing, RPC or UHPC wet joint treatment process, the stress and waterproof performance is improved, and then the overall durability of the structure is improved.
本发明公开了一种基于胶拼理论的小分块装配式地铁车站结构，该地铁车站是由若干交替设置的第一拼接环和第二拼接环组成，第一拼接环和第二拼接环之间通过穿入纵向预应力束张拉固定，第一拼接环和第二拼接环是由若干预制构件拼合成的，且第一拼接环与第二拼接环上的预制块相互错缝设置，各个预制块之间的接缝处采用胶拼工艺进行连接，连接后再穿入横向预应力束和竖向预应力束张拉固定。减小了每个预制块的体积和重量，方便运输及现场施工；将墙、柱、板的连接处易产生应力集中的位置均做成一个预制构件，能提高薄弱结构节点的受力性能；接缝处利用胶拼、RPC或UHPC湿接缝的处理工艺进行连接，提高了受力及防水性能，进而增加结构整体耐久性。
