A special-shaped column node connection structure for prefabricated buildings

Abstract

The invention belongs to the technical field of prefabricated buildings, in particular to a special-shaped column node connecting structure for prefabricated buildings. The special-shaped column nodeconnecting structure comprises special-shaped columns and transverse beams perpendicular to the special-shaped columns, wherein a plurality of reinforcing parts are arranged at connecting parts of thetransverse beams and the special-shaped columns and are distributed at the two sides of the transverse beams; the reinforcing parts are fixed to the transverse beams and reinforcing parts through bolts in a screw joint manner; by arranging the plurality of reinforcing parts at the connecting parts of the transverse beams and the special-shaped columns, the transverse beams can be fixed from the upper parts, lower parts and middle parts of the transverse beams; the bolts are used for fixing the reinforcing parts, the transverse beams and the special-shaped columns, so that the special-shaped column node connecting structure is convenient to install by a worker, and the installation time is shortened; the bolts extending into a cavity part are bound by longitudinal reinforcing ribs and transverse reinforcing ribs, and then the cement concrete is poured into the cavity; the bolts are fixed by cement in a manner of combining cement pouring and bolt installation; and the structure can be relatively stable while the installation time is shortened.

Description

technical field [0001] The invention belongs to the technical field of prefabricated buildings, and in particular relates to a special-shaped column node connection structure for prefabricated buildings. Background technique [0002] In prefabricated buildings, special-shaped columns are an important component. The special-shaped columns have the characteristics of the same thickness as the wall material, so it can avoid the problem that the corners of the columns protrude from the wall, improve the "room rate", and make the interior of the building The bays are larger and can be combined and split, which helps to improve living comfort and livability. The special-shaped column includes multiple side plates, which form multiple cavities. The cavity of the special-shaped column needs to be poured with concrete, and the side plates of the special-shaped column are connected with steel beams to form a beam-column joint structure. For mechanical performance, it is generally nec...

Problems solved by technology

[0003] The beam-column joint is the most important joint in the fabricated steel structure system, which directly affects the construction speed and the degree of assembly of the structure. Therefore, the beam-column joints should be connected with high-strength bolts that are easy to operate as much as possible, and the bolts should be arranged as far as possible. The ground is easy for workers to fasten on site, but if a large number of bolts are used, because the bolts are easy to loosen during the matching process, although it is more convenient, it will also lead to loosening of the connection structure of the nodes
