Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a tubular column and corbel connection structure component. Background Technology

[0002] Using corbel components on tubular columns to connect with beams is a typical connection method in steel structure buildings. Specifically, the corbel components are pre-welded to the outer surface of the tubular column. During construction, the ends of the beams are fixed to the corbel components with fasteners. In this way, the tubular column is used to bear the load from the beams.

[0003] Since the tubular column is a tubular structure, if the load from the crossbeam is large, the wall of the section where the column connects to the crossbeam may deform. To avoid deformation in this section, ring-shaped components are welded to the inner hole of the tubular column at the corresponding positions on the upper and lower parts of the bracket component.

[0004] As is well known, during construction, concrete needs to be poured into the inner hole of the tubular column. After the concrete solidifies, it can increase the bending strength of the tubular column. However, because the annular component fixed inside the inner hole of the tubular column has an upward cutting effect on the concrete, the density of the concrete in the section near the annular component is poor. Furthermore, because the inner hole of the annular component is small, the bonding ability of the concrete at the annular component is greatly reduced, thus affecting the bending capacity of the tubular column. Moreover, the effect of suppressing the deformation of the column wall by the annular component alone is not good. Utility Model Content

[0005] In view of the above-mentioned technical problems existing in the prior art, the embodiments of this utility model provide a tubular column and bracket connection structure component.

[0032] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0033] like Figures 1 to 5 As shown, this utility model discloses a tubular column 10 and bracket 20 connection structure assembly, which includes: tubular column 10, bracket 20 and internal support structure 30.

[0034] The bracket 20 has an inner end and an outer end. The inner end of the bracket 20 is welded to the outer circumferential surface of the tubular column 10, and the outer end of the bracket 20 is connected to a crossbeam (not shown) by fasteners. Preferably, the bracket 20 is configured as an I-beam with a web in the middle. Multiple brackets 20 can be welded to the outer circumferential surface of the tubular column 10 to connect multiple crossbeams. The lower end of the tubular column 10 is fixedly connected to the foundation by a flange.

[0035] The inner support structure 30 is placed in the inner hole of the tubular column 10 and corresponds to the section where the corbel 20 is located. The inner support structure 30 is fixed to the tubular column 10 by welding. The inner support structure 30 includes: two annular components 31, multiple vertical strips 32, and steel mesh rings 33 assembled on each annular component 31.

[0036] Each annular component 31 includes an outer ring portion 311, an inner ring portion 312, and a plurality of circumferentially arranged ribs 313 between the outer ring portion 311 and the inner ring portion 312. Each pair of adjacent ribs 313 defines a hollow portion 314, thereby having a plurality of circumferentially arranged hollow portions 314 between the outer ring portion 311 and the inner ring portion 312 of the annular component 31.

[0037] Each annular component 31 has a beveled outer ring 311 for welding and fixing to the inner wall of the tubular column 10. The two annular components 31 are arranged vertically and horizontally, corresponding to the upper and lower parts of the inner end of the bracket 20, respectively. This reduces the deformation of the tube wall caused by the force and torque applied by the bracket 20 to the tubular column 10. During the construction operation of pouring concrete into the tubular column 10, the concrete can flow to the bottom of the annular component 31 through the inner hole of the inner ring 312 and the numerous perforations 314, thereby reducing the resistance of the annular component 31 to the concrete. After the concrete solidifies, the concrete is connected not only through the inner hole of the inner ring 312 but also through the numerous perforations 314, thereby limiting the increase of the bonding force of the concrete in the section where the annular component 31 is located and reducing the influence of the annular component 31 on the bonding force of the concrete.

[0038] The inner ring portion 312 of the annular component 31 is machined with numerous radially arranged holes 315. The reinforcing mesh ring 33 is woven and welded into shape, and has circumferentially arranged reinforcing bar ends 331. At the prefabrication site or factory, the reinforcing bar ends 331 of the reinforcing mesh ring 33 are inserted into the radial holes 315 and welded. After the annular component 31 is welded to the tubular column 10 and concrete is poured into the tubular column 10 and the concrete has solidified, the reinforcing mesh ring 33 can significantly increase the bonding force between the annular component 31 and the concrete.

[0039] Multiple vertical strips 32 are simultaneously welded and fixed to two annular components 31 arranged above and below, and multiple vertical strips 32 are also welded and fixed to tubular columns 10. Specifically, at the prefabrication site or prefabrication plant, each vertical strip 32 has two notches 321, which are arranged at intervals. The two notches 321 are inserted into the ribs 313 of the two annular components 31 from the radial inside and are welded to the ribs 313. In this way, the vertical strips 32 are simultaneously welded and fixed to the two annular components 31, and multiple vertical strips 32 are arranged circumferentially. The integrally welded vertical strips 32 and annular components 31 are inserted into the tubular column 10. The radially outer side of the vertical strips 32 is welded to the inner wall of the tubular column 10, thereby fixing all the vertical strips 32 to the tubular column 10. These vertical strips 32 not only suppress deformation of the tubular column 10 wall but also improve the bending stiffness of the tubular column 10. Furthermore, their radially inward protrusion also improves the torsional stiffness of the tubular column 10. Preferably, the radially inner side of each vertical strip 32 protrudes from the inner hole of the inner ring portion 312 of the annular component 31, allowing the vertical strip 32 to penetrate into the concrete and improve the torsional stiffness of the annular component 31. Preferably, wedge-shaped portions 322 are machined at both ends of each vertical strip 32 in the axial direction to reduce the impact of the ends on concrete flow.
