Embodiment 1

[0050] to combine Figure 2 to Figure 4 As shown, this embodiment provides a separate corbel node structure for beam-to-column connection of steel structures, including: a steel column 1 and a steel beam 2; wherein,

[0051] The end of the steel column 1 is provided with a flange base 4, and the outer wall of the steel column 1 is provided with a separate corbel flange plate 3 at a predetermined length from the flange base 4;

[0052] The flange bases 4 at the ends of the adjacent upper and lower steel columns 1 are connected by high-strength bolts, and the ends of the steel beams 2 are clamped between the flange bases 4 at the ends of the adjacent upper and lower steel columns. In between, the upper and lower flanges of the steel beam 2 are fixedly connected to the flange bases 4 at the ends of the upper and lower steel columns respectively through high-strength bolts 7 .

[0053] In this embodiment, as a further technical solution, the distance between the flange bases 4 at...

Embodiment 2

[0058] to combine Figure 5 to Figure 7 As shown, this embodiment provides a method for manufacturing a separate corbel node structure for beam-to-column connection of steel structures, including the following steps:

[0059] S1: Connect the lower flange of the steel beam 2 to the flange base of the lower steel column through high-strength bolts;

[0060] S2: Connect the flange bases of the upper and lower steel columns through high-strength bolts 7;

[0061] S3: Connect the upper flange of the steel beam to the flange base of the upper steel column through high-strength bolts 7 .

[0062] To sum up, the joint structure of the present invention eliminates the on-site butt penetration welding at the flange of the bolt-welded joint and the joint of the column, and realizes the full-bolt assembly on the construction site. At the same time, compared with the traditional full-bolt joint, the Bolts in the beam web section. The shelving and lapping method of the flange is convenie...

Embodiment 3

[0064] like Figure 8-10 As shown, the present invention also discloses a residential structure system with the above node structure, which includes: vertical load-bearing columns, horizontal load-bearing units 20 and prefabricated floor slabs 30;

[0065] Vertical load-bearing column The vertical load-bearing column includes several steel columns connected up and down in sequence;

[0066] The lateral load-bearing unit 20 includes: a lateral load-bearing frame and an enclosure wall 21 arranged outside the lateral load-bearing frame; the lateral load-bearing frame includes a steel beam 2 placed horizontally on the upper edge of the enclosure wall 21; a plurality of vertical load-bearing columns as The vertical load-bearing structure of the building is erected in parallel at intervals; the horizontal load-bearing unit 20 is arranged between two adjacent vertical load-bearing columns; The end 2a is connected to the steel column through the separated corbel node structure;

Abstract

The invention relates to a separated bracket node structure for steel structure beam column connection, a manufacturing method and a residential structure system. The node structure comprises steel columns and a steel girder, wherein the end part of the steel column is provided with a flange plate base; a separated bracket wing edge plate is arranged in a position, with the preset length from theflange plate base, on the outer side wall of the steel column; the adjacent upper and lower steel columns are connected through high-intensity screw bolts; the upper and lower wing edges of the steelcolumns are fixedly connected with the flange plate bases at the end parts of the upper and lower steel columns through high-intensity screw bolts. The mode structure has the advantages that the fieldbutt joint penetration welding at bolting and welding connection node wing edges and column connection parts is omitted; the full screw bolt assembly in construction sites is realized; meanwhile, compared with a traditional full screw bolt connection node, the node structure omits screw bolts in beam web plate positions. A laying lap joint mode in the wing edge position is used; the beam construction in-position and screw bolt connection is convenient; the construction speed is accelerated.

Description

technical field [0001] The invention relates to the technical field of building structure node connection, in particular to a separate corbel node structure for steel structure beam-column connection, a manufacturing method, and a residential structure system. Background technique [0002] The beam-column central joints of steel structures stipulated in the existing codes and widely used in engineering are bolted and welded joints (the structure of which is as follows: Figure 1a shown), specifically flange butt penetration weld connection and web high-strength bolt connection. Its characteristic is that the column is connected at the node position, and the inner diaphragm is set at the beam flange position in the column, and the flange connection is a butt penetration weld. % weld inspection. In addition, there are fully bolted beam-to-column joints (whose structure is as Figure 1b shown), specifically the flange is also connected by bolts, and the number of bolts in thi...
