Description

Assembled station power transmission key Technical Field The utility model relates to the technical field of force transmission keys, in particular to an assembled station force transmission key. Background Compared with the traditional cast-in-situ underground station, when the assembled station performs structural stress conversion after the steel support is removed, a force transfer key structure is required to be adopted to transfer the horizontal load of the enclosure structure to the middle plate. The fertilizer tank is internally provided with a force transmission key structure, is influenced by the size of the force transmission key structure and the installation process, has wider thickness between the enclosure structure and the station structure, has the width of 50cm generally, and cannot adapt to the working condition of smaller transverse width of the station. Taking Shenzhen five-period subway assembled station as an example, the theoretical gap of a fertilizer groove between an enclosure structure and an assembled station structure is 15cm, a traditional built-in jack type force transmission key structure cannot be smoothly placed from a pit top to a designated position for installation due to large size (often exceeding 30 cm), workers are required to place a long wrench from the pit top for tightening during installation, operation is time-consuming and labor-consuming, and installation accuracy and quality are difficult to guarantee. The post-cast strip dowel bar structure with the seed manure grooves backfilled in advance is disclosed in the publication No. CN217580315U on the day of 10 months and 14 of 2022, and comprises an underground structure of a building concrete main body, wherein the outer side of the underground structure is provided with a manure groove to be backfilled, the underground structure of the building is provided with a post-cast strip for dividing the underground structure, the post-cast strip is provided with a supporting structure which comprises a plurality of supporting structures and is arranged at intervals along the post-cast strip, the supporting structure is arranged at a building frame beam position of the post-cast strip, and two sides of the supporting structure are respectively supported on a post-cast strip section of the frame beam to change the frame beam into the dowel bar. The dowel bar structure disclosed by the above cannot be conveniently installed in a fertilizer groove area with restenosis, and the practicability is poor. Disclosure of utility model The utility model aims to provide an assembled station force transmission key with higher practicability. According to the utility model, the steel support is carried out through the force transmission bolts arranged on the bolt sleeves in the assembled blocks, the quick dismantling of the force transmission bolts is realized through the cooperation of the force transmission bolts and the detachable rotating parts, and the whole force transmission key is convenient and quick to use, convenient to install in a narrow position and convenient and quick to use.
