Description

Technical Field

[0001] The invention relates to the technical field of building engineering, and in particular to a component used for connecting a concrete structural column with a steel structure column. Background Art

[0002] Masonry walls are an important part of building structures and are the most common in the construction process. The quality of their construction and the implementation of technical points are necessary conditions for the stability and safety of buildings. However, non-load-bearing masonry walls exist in a variety of situations, some are high, some are low, some are long, some are short, some are thick, and some are thin. For super-high masonry walls, ring beams need to be added, and for super-long masonry walls, structural columns need to be added. Structural columns or ring beams are generally connected to the primary structure. Our common primary structure is reinforced concrete beams and columns. In this case, we can use chemical reinforcement technology to achieve the connection between the primary structure and the structural columns in the secondary structure.

[0003] However, when the primary structure is a steel column, the structural column of the masonry wall cannot be connected to the steel column by conventional chemical reinforcement technology. If a strong connection between the steel column and the concrete column cannot be established, the stability of the building structure will be seriously affected, especially the inability to cope with the destructive force of an earthquake. Therefore, it is necessary to develop a component for connecting the concrete column to the steel column. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] The following embodiments may be understood as explaining a local structure of the present invention individually, or may be understood as explaining a larger structure of the present invention through a combination of multiple embodiments.

[0024] A component used to tie a concrete structural column to a steel structural column, such as Figure 1-5 As shown, it includes a tie steel plate 1, one end of which is provided with a through hole and a sleeve 2 is coaxially welded at the through hole, the sleeve 2 is used to be sleeved outside a steel structure column 6 and welded to the steel structure column 6, and the end of the tie steel plate 1 away from the through hole is welded with a second-order shock-absorbing structure, and the second-order shock-absorbing structure is distributed on the upper and lower surfaces of the tie steel plate 1.

[0025] like Figure 5As shown, the tie steel plate 1 is formed by splicing a first steel plate 11 and a second steel plate 12, and the sleeve 2 is formed by splicing two semicircular arc-shaped plates (a first arc-shaped plate 13 and a second arc-shaped plate 14). The first steel plate 1 is an arc-shaped steel plate, and the first arc-shaped plate 13 is welded to the inner edge of the arc-shaped steel plate. The second steel plate 2 is a square steel plate with a width consistent with the outer diameter of the arc-shaped steel plate. An arc-shaped groove is provided on the square steel plate toward one end of the arc-shaped steel plate, and a second arc-shaped plate 14 is welded in the arc-shaped groove. When the first steel plate 1 and the second steel plate 2 are butt-jointed, the first arc-shaped plate 13 and the second arc-shaped plate 14 are butt-jointed to form a complete sleeve structure. The tie steel plate 1 is sleeved on the outside of the steel structure column 6 and is welded at the joints of the first steel plate 1 and the second steel plate 2 and the first arc-shaped plate 13 and the second arc-shaped plate 13.

[0026] like Figure 1 As shown, the second-order shock-absorbing structure includes a continuous low-carbon steel bar 4 and an intermittent low-carbon steel bar 5 welded to the upper surface of the second steel plate 12 in the longitudinal direction. The continuous low-carbon steel bar 6 constitutes a primary shock-absorbing mechanism. During an earthquake, energy-consuming deformation occurs due to the horizontal shear force. The intermittent low-carbon steel bar 5 includes a first steel bar 51 and a second steel bar 52 arranged side by side. A gap is left at the opposite ends of the first steel bar 51 and the second steel bar 52. The intermittent low-carbon steel bars constitute a secondary shock-absorbing mechanism. When the horizontal shear force causes the opposite ends of the first steel bar and the second steel bar to abut against each other, the secondary shock-absorbing mechanism takes effect, thereby greatly improving the seismic performance of the present invention.

[0027] like Figure 2 As shown, the second-order shock-absorbing structure also includes a continuous low-carbon steel bar 4 and a discontinuous low-carbon steel bar 5 welded to the lower surface of the second steel plate 12 in the transverse direction. The continuous low-carbon steel bar 4 constitutes a primary shock-absorbing mechanism, and the discontinuous low-carbon steel bar 5 includes a first steel bar 51 and a second steel bar 52 arranged side by side, with a gap left at the opposite ends of the first steel bar 51 and the second steel bar 52, and the discontinuous low-carbon steel bar 5 constitutes a secondary shock-absorbing mechanism. The continuous low-carbon steel bars and the discontinuous low-carbon steel bars located on the upper and lower surfaces of the second steel plate have different directions, so that the energy dissipation of earthquake shear forces in different directions can be achieved.

[0028] like Figure 1-4 As shown, a triangular stiffening rib plate 3 is welded between the outer surface of the sleeve 2 and the outer surface on the same side of the first steel plate 11 or the second steel plate 12. The stiffening rib plate 3 and the sleeve 2 are used together to strengthen the longitudinal seismic resistance of the tie steel plate 1, making the connection between the steel structure column 6 and the concrete structural column 7 more stable.

[0029] like Figure 4 As shown, the steel cage of the concrete structural column 7 is pre-embedded with tie steel bars 8 extending toward one side of the tie steel plate 1 , and the tie steel bars 8 are welded to the tie steel plate 1 .

[0030] like Figure 4 As shown, the tie steel bar 8 is welded to the outer surface of the tie steel plate 1 and the continuous low-carbon steel bar 4 at the same time.
