Embodiment Construction

[0026] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be further described below.

[0027] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, the present invention proposes an in-line bolt-free connection node between a closed cavity column and a steel beam of a three-layer ring plate structure, including a first steel column 1, at least one first steel beam 2, at least one first steel beam The second steel girder 3 and the steel girder are inserted into the steel structure;

[0028] The steel beam plug-in steel structure includes the upper ring plate 4, the middle ring plate 5 and the lower ring plate 6. The upper ring plate 4, the middle ring plate 5 and the lower ring plate 6 are coaxially arranged up and down at a certain distance. A connecting column 7 is arranged between the ring plates;

[0029] The steel beam plug-in steel structure is welded to the...

Abstract

The invention provides a direct-insertion type bolt-free connecting joint of a closed cavity column and steel beams of a three-layer annular plate structure. The direct-insertion type bolt-free connecting joint comprises a first steel column, at least one first steel beam, at least one second steel beam and a steel beam insertion steel structure; and the steel beam insertion steel structure comprises an upper annular plate, a middle annular plate, a lower annular plate and a connecting column. The beam column insertion structure is simple in structure and clear in force transmission; after bolts are omitted, a large number of bolt holes do not need to be formed in webs of the steel beams, base metal is free of loss, shearing force is better transmitted, secondary conduction of a traditional bolt connecting joint is omitted, and the overall stress structure is excellent. A large number of high-strength bolts and double-face clamping plates are omitted, and cost is greatly reduced. The steel beams and the column are connected in an inserted mode, the perpendicularity and flatness of a frame can be adjusted, the installation difficulty is reduced, the construction period is shortened, and the installation cost is reduced. In addition, the three-layer annular plate structure is adopted, and the direct-insertion type bolt-free connecting joint is suitable for the situation that the beam heights are different in the construction stage and wider in application range.

Description

technical field [0001] The invention relates to the field of building technology, in particular to a plug-in bolt-free connection node between a closed cavity column and a steel beam of a three-layer ring plate structure. Background technique [0002] The traditional typical method of connecting columns with closed cavities such as round tubes and rectangular tubes to steel beams is to assemble and weld the corbels on the steel columns, and then use high-strength bolts to the web of the steel beams, and some require Add splints and bolt connections. For frame structures with heavy loads, the amount of bolts used for beam-to-column connection joints is huge, the cost is high and the construction is cumbersome. Contents of the invention [0003] The purpose of the present invention is to propose a beam-column plug-in joint that saves the amount of bolts, optimizes the beam-column stress structure, and is applicable to various beam heights. [0004] In order to achieve the ...
