Description

Technical Field

[0001] The utility model relates to the technical field of building components, and particularly relates to a concrete-filled steel tube column. Background Technique

[0002] A concrete-filled steel tube column is a structural member formed by filling concrete in a steel tube. It combines the advantages of both steel tube and concrete. This column not only has the high strength and good ductility of the steel tube, but also significantly improves the compressive strength and stiffness due to the filling of concrete. Concrete-filled steel tube columns are widely used in high-rise buildings, bridges and other projects, and are favored for their strong load-bearing capacity, good seismic performance, convenient construction and remarkable economic effects. Their cross-sectional forms are diverse, including circular, square, rectangular, etc., to meet different engineering requirements. In specific applications, the design and construction of concrete-filled steel tube columns need to follow relevant standards and specifications to ensure the safety and durability of the structure.

[0003] During the implementation of this solution, the inventor found that the following problems in the prior art have not been well solved: The splicing part of the concrete-filled steel tube column is connected by angle steel, steel plates and bolts. The angle steel is welded to the outer wall of the steel tube, and the upper and lower angle steels are installed together with the steel plates through bolts. As a temporary reinforcement, although the installation is simple, when removing, the angle steel needs to be cut, and it is very easy to damage the outer wall of the steel tube during cutting, resulting in scars. If the angle steel is not completely cut, the remaining part of the angle steel will protrude outward, affecting the aesthetics. At the same time, when the staff works near it, it is also easy to cause scratching, having a certain safety hazard. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a concrete-filled steel tube column, which can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A concrete-filled steel tube column includes two concrete-filled steel tube columns, which are vertically distributed up and down. There are multiple reinforcement mechanisms arranged on the outer walls between the concrete-filled steel tube columns. Each reinforcement mechanism includes two arc-shaped reinforcement main boards. At both ends of the side wall of each arc-shaped reinforcement main board away from the concrete-filled steel tube column, connection screws are provided. Between two mutually perpendicular connection screws, reinforcing ribs are provided. At the top and bottom of each reinforcing rib, connection sleeves are welded. The outer walls of the connection screws are all threadedly connected with connection nuts.

[0007] Preferably, the connection screws are respectively welded and connected to the arc-shaped reinforcement main boards.

[0008] Preferably, the connecting sleeves are respectively sleeved on the outer walls of the connecting screws, and the inner diameter sizes of the connecting sleeves respectively match the outer diameter sizes of the connecting screws.

[0009] Preferably, the connecting nuts are respectively in contact with the side walls of the connecting sleeves away from the arc-shaped reinforcement main board.

[0010] Preferably, a reinforcing rib frame is arranged between every two adjacent reinforcing ribs, and the reinforcing rib frames are respectively connected to the adjacent ends of the reinforcing ribs by welding.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] First, the arc-shaped reinforcement main board is welded to the outer wall of the concrete-filled steel tube column. A plurality of arc-shaped reinforcement main boards on two concrete-filled steel tube columns are perpendicular to each other. The connecting sleeves at the top and bottom of the reinforcing ribs are respectively sleeved on the connecting screws at the front end of the arc-shaped reinforcement main board. Then, the connecting nuts are threadedly connected to the connecting screws, so that the connecting sleeves are abutted against the arc-shaped reinforcement main board. At this time, the two perpendicular arc-shaped reinforcement main boards are supported by the connecting screws, connecting sleeves and reinforcing ribs. This kind of support not only has a good support effect, but also is convenient to disassemble. At the same time, the connecting screws can be directly cut, and the arc-shaped reinforcement main board can be directly left on the outer wall of the concrete-filled steel tube column. The arc-shaped reinforcement main board does not protrude significantly outward and will not cause scratches to the staff. And when cutting the connecting screws, due to the blocking of the arc-shaped reinforcement main board, the concrete-filled steel tube column will not be cut, playing an effective protection role.

[0018] To make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] As Figures 1-4 shown, a concrete-filled steel tubular column includes two concrete-filled steel tubular columns 1, which are vertically distributed up and down. A plurality of reinforcement mechanisms 2 are arranged on the outer walls between the concrete-filled steel tubular columns 1. The reinforcement mechanism 2 includes two arc-shaped reinforcement main plates 21. At both ends of the side wall of the arc-shaped reinforcement main plate 21 away from the concrete-filled steel tubular column 1, connecting screws 22 are arranged. Between two perpendicular connecting screws 22, reinforcing ribs 23 are provided. Connecting sleeves 24 are welded to the top and bottom of the reinforcing ribs 23. Connecting nuts 25 are threadedly connected to the outer walls of the connecting screws 22.

[0020] In this embodiment, the connecting screws 22 are respectively welded and connected to the arc-shaped reinforcement main plates 21.

[0021] In this embodiment, the connecting sleeves 24 are respectively sleeved on the outer walls of the connecting screws 22, and the inner diameter sizes of the connecting sleeves 24 respectively match the outer diameter sizes of the connecting screws 22. The connecting nuts 25 are respectively in contact with the side walls of the connecting sleeves 24 away from the arc-shaped reinforcement main plates 21, so that the connecting sleeves 24 can be extruded and limited.

[0022] In this embodiment, between adjacent two reinforcing ribs 23, reinforcing rib frames 26 are arranged. The reinforcing rib frames 26 are respectively welded and connected to the adjacent ends of the reinforcing ribs 23, so that the reinforcing ribs 23 can strengthen the support between adjacent arc-shaped reinforcement main plates 21 through the reinforcing rib frames 26.

[0023] Working principle:

[0024] First, the arc-shaped reinforcement main plates 21 are welded to the outer walls of the concrete-filled steel tubular columns 1. A plurality of arc-shaped reinforcement main plates 21 on the two concrete-filled steel tubular columns 1 are perpendicular to each other. The connecting sleeves 24 at the top and bottom of the reinforcing ribs 23 are respectively sleeved on the connecting screws 22 at the front ends of the arc-shaped reinforcement main plates 21. Subsequently, the connecting nuts 25 are threadedly connected to the connecting screws 22, so that the connecting sleeves 24 are abutted against the arc-shaped reinforcement main plates 21. At this time, between two perpendicular arc-shaped reinforcement main plates 21, support is carried out through the connecting screws 22, the connecting sleeves 24 and the reinforcing ribs 23. This kind of support not only has a good support effect, but also is convenient to disassemble. At the same time, the connecting screws 22 can be directly cut, and the arc-shaped reinforcement main plates 21 can be directly left on the outer walls of the concrete-filled steel tubular columns 1. The arc-shaped reinforcement main plates 21 do not protrude significantly outward and will not cause scratches to the staff. And when cutting the connecting screws 22, due to the blocking of the arc-shaped reinforcement main plates 21, the concrete-filled steel tubular columns 1 will not be cut, playing an effective protective role.
