Butt joint structure of prefabricated prefabricated columns and prefabricated beams and its butt joint construction method

Abstract

The invention discloses a butt joint structure of fabricated prefabricated columns and prefabricated beams and a butt joint construction method of the butt joint structure, and belongs to the technical field of building construction. The butt joint structure comprises a prefabricated column body and a prefabricated beam body, a cylinder is arranged at the top of the prefabricated column body, an elastic assembly is arranged outside the cylinder, and fabricated holes used for accommodating the cylinder and the elastic assembly are formed in the prefabricated beam body; the elastic assembly comprises a first arc piece and a second arc piece, wherein the first arc piece and the second arc piece are arranged oppositely and arranged outside the cylinder in a sleeving mode, the opposite ends ofthe first arc piece and the second arc piece are connected through a plurality of first elastic columns, the first arc piece and the second arc piece are further connected with the cylinder through aplurality of second elastic columns, and a plurality of first longitudinal threaded holes are further formed in the top of the prefabricated column body. According to the butt joint structure, the cylinder is arranged at the top center of the prefabricated column body, the elastic assembly is arranged on the periphery of the cylinder to limit relative displacement of the beams and the columns, thestability performance of beam-column joints is improved, the butt joint method is simple to operate, and the construction difficulty is low.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a butt joint structure of an assembled prefabricated column and a prefabricated beam and a butt joint construction method thereof. Background technique [0002] Due to the long construction period of the cast-in-place structure, it is difficult to guarantee the quality of the project, and the cost is difficult to control, etc., while the prefabricated structure has certain advantages. The prefabricated structure is to pour concrete into independent prefabricated columns or Prefabricated beams are then transported to the construction site, assembled and lapped to form a building structure. In a prefabricated structure, the connection mode between components determines the overall stability of the structure. Therefore, it is necessary to design a docking that is convenient and stable. Structure and docking method. Contents of the invention [0003] The purpose of t...
