Dry connection structure and method of precast concrete column

Abstract

The invention discloses a dry connection structure of a precast concrete column. The dry connection structure comprises a precast column and a precast beam, wherein column embedded parts are precast on the precast column, beam embedded parts are precast at the two sides of the precast beam respectively, the outer sides of the beam embedded parts are provided with angle irons, the vertical faces ofthe angle irons are spirally fixed with the beam embedded parts through first bolts, the planes of the angle irons and the bottom face of the precast beam all abut against the beam embedded parts, second bolts penetrates through the precast beam, the top end of the precast beam is provided with nuts, the lower ends of the second bolts are spirally fixed with the column embedded parts, and the upper ends of the second bolts are spirally fixed with the nuts. The dry connection structure of the precast concrete column has the advantages that the angle irons and the embedded parts are constructedthrough the preset design, the assembly connection of the precast concrete columns can be achieved only through a dry connection mode on site; compared with the prior art, the site construction difficulty is greatly reduced, the construction time is effectively shortened, and the construction cost is saved better.

Description

technical field [0001] The invention relates to a concrete column connection structure, in particular to a prefabricated concrete column connection structure and method. Background technique [0002] At present, my country has gradually accelerated the pace of industrialized buildings and vigorously developed prefabricated buildings, resulting in a wider application of prefabricated concrete floors. The node connection problem has always been a key design problem for prefabricated concrete structures. At present, prefabricated concrete structures mostly use dry-wet joint connection methods, which have disadvantages such as difficult design and construction and long construction time, so it is difficult to meet application requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a prefabricated concrete column trunk connection structure and method that can reduce construction difficulty, shorten construction ...
