Connecting structure and connecting method of assembly type prefabricated part

Abstract

The invention provides a connecting structure of an assembly type prefabricated part. The connecting structure of the assembly type prefabricated part comprises a first prefabricated part, a second prefabricated part and a cast-in-place structural part. Steel bar frames are reserved on the first prefabricated part and the second prefabricated part. Each steel bar frame comprises an upper main rib,a lower main rib and a connecting rib, the lower main rib partially extends into the prefabricated part, the part, extending out of the prefabricated part, of the lower main rib, the upper main rib and the connecting rib are all arranged in the cast-in-place structural part, and the steel bar frame of the first prefabricated part and the steel bar frame of the second prefabricated part are partially overlapped in the cast-in-place structural part. The invention further provides a connecting method of the assembly type prefabricated part. According to the invention, a steel bar frame structuredesign is adopted at a joint of the prefabricated part, and the steel bar frames of the two prefabricated parts are overlapped and lapped and then are cast in place to form an integral structure, sothat rigid connection between the two prefabricated parts is realized, the bearing capacity and durability of the connecting structure are ensured, and the problem that a connecting joint of an existing assembly type prefabricated part is easy to leak water is solved.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and specifically relates to a connection structure and a connection method of prefabricated components, which are applicable to the design and construction scheme of prefabricated components of prefabricated structures such as underground stations, basements, comprehensive pipe corridors, and above-ground structures of rail transit projects. Background technique [0002] At this stage, most structures are constructed with cast-in-place reinforced concrete. The construction environment is poor, the process is complicated, and the speed is slow. It is greatly affected by various weather and climate, and the construction quality is difficult to guarantee due to various factors. construction waste, which wastes resources and pollutes the environment. [0003] With the advancement of science and technology, the development of the equipment manufacturing industry, and industrial upgrad...
