Description

Technical Field

[0001] The utility model relates to a box-type column bolt welding splicing node structure, belonging to the field of steel structure. Background Art

[0002] At present, the columns of steel structure buildings or super high-rise buildings usually adopt box-type columns. Box-type columns are divided into sections according to the needs of on-site construction, processed in sections in the factory, and welded on-site. At present, most of the box-type column splicing on site is still constructed and installed in accordance with the "Detailed Construction Drawing of Steel Structure Nodes of Multi-story Civil Buildings". This method uses upper and lower ear plates at the splicing nodes of box-type columns, and uses double-ply bolt connection to position them. The splicing welds are welded on-site, and the welds here are required to be first-class welds.

[0003] This traditional connection and positioning method does not take into account the adverse effects of the upper and lower ear plate welding deviation and the double plywood displacement. The upper and lower column sections often have large displacement problems on site, and the splicing weld is long, resulting in low efficiency of box column splicing. On-site welding of the first-level weld has high welding requirements and is difficult to ensure welding quality, thus affecting the splicing quality of the box steel column. Utility Model Content

[0020] The technical features of the present invention are further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] As shown in the figure, this embodiment is a box-type column bolt welding joint structure, including an upper column and a lower column.

[0022] The lower column mainly includes a box column 101 and a flange 301, and the connection and fixation of these two parts are completed in the factory production stage.

[0023] In this embodiment, the box-type column 101 is a square columnar box, and both ends of the box-type column 101 have openings. The flange 301 is an annular disk with a central opening. The shape of the central opening of the flange 301 matches the shape of the end of the box-type column 101. The end of the box-type column 101 is inserted into the central opening of the flange 301 and fixedly connected by welding. At this time, the end surface of the box-type column 101 is in contact with the flange 301. Figure 1 The lower surface of the middle flange 301 is flush.

[0024] In order to increase the connection firmness between the box column 101 and the flange 301, the side surface of the box column 101 and the upper surface of the flange 301 are connected by rib plates 2, and the two sides of these rib plates 2 are respectively welded and fixed to the side surface of the box column 101 and the upper surface of the flange 301.

[0025] The upper column mainly includes a box column 102 and a flange 302, and the connection and fixation of these two parts are completed in the factory production stage.

[0026] In this embodiment, the box-type column 102 is a square columnar box, and both ends of the box-type column 102 have openings. The flange 302 is an annular disk with a central opening. The shape of the central opening of the flange 302 matches the shape of the end of the box-type column 102. The end of the box-type column 102 is inserted into the central opening of the flange 302 and fixedly connected by welding. At this time, the end surface of the box-type column 102 is connected to the flange 302. Figure 1 The upper surface of the second middle flange 302 is flush.

[0027] In order to increase the connection firmness between the box-type column 102 and the flange 302, the side surface of the box-type column 102 and the upper surface of the flange 302 are connected by rib plates 2, and the two sides of these rib plates 2 are respectively welded and fixed to the side surface of the box-type column 102 and the upper surface of the flange 302.

[0028] During the on-site construction stage, when the box column 101 and the box column 2 102 are butt-jointed, the inner sleeve 4 is used to position the butt-jointed installation of the box column 101 and the box column 2 102, and after the butt-jointed, the inner sleeve 4 is used to provide internal support to the butt joint of the box column 101 and the box column 2 102.

[0029] When installing and docking on site, first insert one end of the inner sleeve 4 into the opening of the box-type column 101 with a flange 301 at one end, and perform plug welding through the plug welding hole 6 on the side surface of the box-type column 101 to weld and fix the box-type column 101 and the inner sleeve 4.

[0030] When the box-type column 101 is docked with the box-type column 102, one end of the box-type column 101 having the flange 1 301 is docked with one end of the box-type column 102 having the flange 2 302. At this time, the inner sleeve 4 is inserted into the end opening of the box-type column 102, and the plug welding operation is performed through the plug welding hole 6 on the side surface of the box-type column 102 to weld the box-type column 102 and the inner sleeve 4 to fix them.

[0031] The side surfaces of both ends of the inner sleeve 4 are respectively attached to the inner side wall of the box column 101 and the inner side wall of the box column 2 102. The inner side is supported and guided for docking, so as to improve the docking efficiency and increase the supporting effect.

[0032] After the box-type column 101 and the box-type column 2 102 are butt-jointed, the flange 1 301 and the flange 2 302 are fitted together and fixedly connected by bolts 5 .

[0033] The following further describes the usage of this embodiment in conjunction with a construction example.

[0034] During on-site splicing, first insert the inner sleeve 4 into the opening of the box-type column 101 with the flange 301 at one end and fix it by plug welding. When the box-type column 101 and the box-type column 2 102 are butt-jointed, align the opening of the box-type column 2 102 with the end of the inner sleeve 4 protruding from the box-type column 101 and directly insert it, so that the end of the inner sleeve 4 protruding from the box-type column 101 completely enters the box-type column 2 102, ensuring that the upper column and the lower column are accurately positioned without displacement deviation.

[0035] Then, flange plate 1 301 and flange plate 2 302 are completely installed and fastened with high-strength bolts, and finally, the four-sided plug welding holes of box-type column 2 102 are plug welded to complete the on-site splicing of the entire box-type column.

[0036] This node transmits node bending moment through high-strength bolts and plug welding, and transmits node shear force through an inner sleeve. The internal force transmission path is clear and can meet the node force requirements.

[0037] The box-type column bolt welding splicing node of the present application is convenient and quick to install on site, which can not only ensure that the splicing has no deviation and displacement, and the internal force is reliably transmitted, but also reduce the workload of on-site welding and improve the installation efficiency.

[0038] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should fall within the protection scope of the present invention.
