Abstract

The invention relates to a concrete prefabricated part transverse connecting joint. The concrete prefabricated part transverse connecting joint comprises a first prefabricated plate and a second prefabricated plate; a plurality of transverse bolt sleeves are pre-buried in the transverse connecting end of the first prefabricated plate; a transverse connecting steel plate is arranged at the transverse connecting end of the second prefabricated plate; the transverse connecting steel plate abuts against the transverse connecting end of the first prefabricated plate and is connected with the transverse bolt sleeves in an assembled mode through a plurality of transverse bolts; and concrete is cast in place at the connecting joint and wraps the transverse connecting steel plate. In addition, the invention relates to a fabricated underground station adopting the concrete prefabricated part transverse connecting joint. Transverse connection between the two prefabricated plates is achieved through the transverse connecting steel plate-transverse bolt sleeve-transverse bolt assembly structure, operation is convenient, and the connecting structure is high in reliability; and then the concrete prefabricated part transverse connecting joint is a steel plate-concrete joint through the cast-in-place concrete, and the structural reliability and stress performance of the connecting joint can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, in particular to the technical field of underground station construction, in particular to a horizontal connection node of a concrete prefabricated part and an assembled underground station using the horizontal connection node of the concrete prefabricated part. Background technique [0002] Most underground stations are constructed with cast-in-place reinforced concrete. The construction environment is poor, the process is complicated, the construction period is long, and it is greatly affected by various weather and climate. It is difficult to guarantee the construction quality due to various factors. Abandoned construction waste not only wastes resources but also pollutes the environment. [0003] With the gradual application of prefabricated construction, prefabricated construction of underground stations has also been promoted, which can significantly improve the constructio...
