Fabricated structure side wall prefabricated member and connection structure thereof with arched plate

Abstract

The invention belongs to the underground engineering construction technology field, and particularly relates to a fabricated structure side wall prefabricated member. The fabricated structure side wall prefabricated member comprises a side wall prefabricated member body, wherein a support face is arranged at the top of the side wall prefabricated member body, a first connection piece with at leasta part embedded in the side wall prefabricated member body is arranged on the support face, and the first connection piece comprises first connection plates used for connecting with an arced plate ina positioning mode. The invention further provides a connection structure of the fabricated structure side wall prefabricated member and the arched plate. The connection structure comprises the arched plate and the above side wall prefabricated member, wherein an arc-shaped prefabricated member is supported on the side wall prefabricated member, the arc-shaped prefabricated member and the side wall prefabricated member body are connected through a cast-in-place structure, a second connection piece is arranged at one end of the arc-shaped prefabricated member, and the second connection piece is connected with the first connection plates in the positioning mode. The first connection plates on the fabricated structure side wall prefabricated member and second connection plates on the arc-shaped plate are connected in the positioning mode, and the arc-shaped prefabricated member and the side wall prefabricated member body are connected through the cast-in-place structure, and then a three-hinged arch structure is formed, and furthermore realization of underground column-free vault large space effect is facilitated.

Description

technical field [0001] The invention belongs to the technical field of underground engineering construction, and in particular relates to an assembled structure side wall prefabricated part and its connection structure with an arched plate. Background technique [0002] At present, the traditional cast-in-place reinforced concrete structure is mostly used in the construction of the structure. The design process is complicated and the workload is heavy. The on-site construction process requires a large number of labor of various types of work. The construction environment is poor, the construction process is complicated, and the construction speed is slow. The impact of various weather and climate is great, and the construction quality is difficult to guarantee; at the same time, a lot of abandoned construction waste will be generated during the construction process, which not only wastes resources but also pollutes the environment.

[0002] At present, the traditional cast-in-place reinforced concrete structure is mostly used in the construction of the structure. The design process is complicated and the workload is heavy. The on-site construction process requires a lot of labor of various types of work. The construction environment is poor, the construction process is complicated, and the construction speed is slow. The impact of various weather and climate is great, and the construction quality is difficult to guarantee; at the same time, a lot of abandoned construction waste will be generated during the construction process, which wastes resources and pollutes the environment

The construction control of cast-in-place concrete structures is uneven. After the completion of the construction, there are often various quality defects in the appearance or interior of the concrete structure due to various reasons. It is difficult to repair later and the quality is difficult to guarantee.

[0003] With the development of prefabricated technology, some prefabricated designs and construction technology schemes have emerged for underground structures, some of which are only suitable for low groundwater and open-cut foundation pits with grading or anchor cables (rods), and are not suitable for The foundation pit adopts internal support and the area with rich groundwater, and more conventional underground structures with columns are used, and the view of the underground space is not wide
