Assembly type PC column-column tenon type bolt connection joint

Abstract

The invention provides an assembly type PC column-column tenon type bolt connection joint. The assembly type PC column-column tenon type bolt connection joint comprises an upper concrete column and a lower concrete column; an upper tenon and an upper mortise are arranged at the bottom of the upper concrete column in a crossed mode in the diagonal direction; a lower tenon and a lower mortise are arranged at the top of the lower concrete column in a crossed mode in the diagonal direction; the upper tenon and the lower mortise are connected in an adaptive and inserted mode, and the upper mortise and the lower tenon are connected in an adaptive and inserted mode; the upper tenon and the lower mortise are connected in an inserted mode, and the upper mortise and the lower tenon are connected in an inserted mode; a steel bar reserved on the upper tenon is aligned with a screw hole reserved in the lower mortise, a steel bar reserved on the lower tenon is aligned with a screw hole reserved in the upper mortise, and the steel bars are fixed in bolt mounting grooves through nuts correspondingly; and the vertical bearing capacity of the concrete columns is transmitted through connection of the upper tenon and the lower tenon, the area of the force transmission section is the same as that of the column section, bolt connection only bears the vertical load of the columns, part of axial force is borne in the normal state, tensile force is borne under the earthquake action, and stress is clear. The assembly type PC column-column tenon type bolt connection joint has the advantages of being simple in structure, convenient to construct, efficient in assembly and high in shear capacity.

Description

technical field [0001] The invention belongs to the technical field of engineering structures, and in particular relates to an assembled PC column-column mortise bolt connection node. Background technique [0002] With the country's vigorous promotion of prefabricated structures, prefabricated PC (prefabricated concrete) structures have gradually become an important direction for residential development. The quality of the prefabricated connection has always been a concern at the construction site of the prefabricated structure. The existing connection methods are mainly divided into two types: dry connection and wet connection. The dry connection does not need to pour concrete at the construction site. , Connectors are all prefabricated in the factory, and connected by bolts or welding; wet connection is to connect the steel bars between the two load-bearing components to each other, and then realize the overall connection of the structure by pouring nodes, so as to achieve...

Problems solved by technology

[0004] In order to overcome the above-mentioned defects in the prior art, the purpose of the present invention is to provide a prefabricated PC column-column tenon type bolted joint, which can solve the problem of low assembly rate of the existing prefabricated column connection and improve the standardization of construction. Clarify the stress path and improve the shear bearing capacity of the prefabricated column connection; it has the characteristics of strong shear bearing capacity, high assembly rate, simple manufacturing process and convenient construction
