Description

Technical Field

[0001] The utility model relates to the technical field of steel tube concrete, in particular to a steel tube concrete column reinforcement structure. Background Art

[0002] Steel tube concrete is to pour concrete into steel tubes and tamp them to increase the strength and rigidity of the steel tubes. Concrete has high compressive strength but weak bending resistance, while steel has strong bending resistance but is prone to instability and loss of axial compressive resistance when under pressure. Steel tube concrete can combine the advantages of both in structure.

[0003] For example, a Chinese patent with announcement number CN217128743U discloses a steel tube concrete column structure, including a steel tube. The steel tube is a hollow structure with a wall and a hollow space. A clamp is provided on the wall, and a clamp groove is provided on the side of the clamp close to the center of the steel tube. There are four clamps, and the four clamps are centrally symmetrically distributed along the circumferential direction. Ribs are clamped between the grooves. Ribs are added to the inner wall of the steel tube, and the ribs are clamped and fixed by the clamps. The ribs are combined to form transverse and longitudinal cross supports, so that the internal structure of the steel tube can be reinforced so that it can withstand greater strength.

[0004] However, the lengths of the transverse plates and the longitudinal plates in this patent are fixed, so this solution can only be applied to the reinforcement of steel pipes with the same internal size, and thus its applicability is low. Utility Model Content

[0025] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0026] Example:

[0027] Reference Figures 1 to 6 The utility model discloses a steel tube concrete column reinforcement structure, comprising a reinforcement member 2 located in a hollow steel tube 1. The reinforcement member 2 comprises a cylinder 4, the cylinder 4 is located in the steel tube 1, and four sliding columns 5 are uniformly slidably penetrated on the outer circumference of the cylinder 4, and a connecting portion 6 is provided on the side of the sliding column 5 away from the cylinder 4.

[0028] A first wedge block 7 and a second wedge block 8 are provided in the cylinder 4. A bottom groove 9 is provided at the bottom of the first wedge block 7, and a top groove 10 is provided at the top of the second wedge block 8. The first wedge block 7 is partially inserted into the top groove 10, and the second wedge block 8 is partially inserted into the bottom groove 9. An adjusting portion 11 is provided in the cylinder 4.

[0029] In this embodiment, the first wedge block 7 and the second wedge block 8 are both inclined on opposite sides (such as Figure 6 As shown in FIG. 1 , due to the opening of the top groove 10 and the bottom groove 9, the first wedge block 7 can move vertically relative to the second wedge block 8. The angle between two adjacent sliding columns 5 is 90°, and the sliding column 5 can be pulled away from the cylinder 4, which is convenient for transporting the device.

[0030] In a further preferred embodiment of the present invention, Figure 1 and Figure 5 As shown, the connecting part 6 includes an extrusion piece 61 installed on the end of the sliding column 5 away from the cylinder 4, the extrusion piece 61 fits against the inner wall of the steel pipe 1, and a clamping block 62 is fixedly connected to the side of the extrusion piece 61 away from the corresponding sliding column 5. A clamping groove 63 is opened on the inner wall of the steel pipe 1, and the clamping block 62 is inserted into the corresponding clamping groove 63.

[0031] In this embodiment, the clamping block 62 is inserted into the clamping groove 63 to pre-fix the device before pouring concrete. The extrusion piece 61 supports the inner wall of the steel pipe 1.

[0032] In a further preferred embodiment of the present invention, Figure 2 and Figure 5 As shown, the extrusion member 61 is a flat plate 611 or an arc plate 612 . The side of the flat plate 611 away from the sliding column 5 is flat, and the side of the arc plate 612 away from the sliding column 5 is arc-shaped.

[0033] In this embodiment, the flat plate 611 is suitable for a steel pipe 1 with a rectangular cross section, and the flat plate 611 can fully fit the inner wall of the steel pipe 1 with a rectangular cross section. The arc plate 612 is suitable for a steel pipe 1 with a circular cross section, and the arc plate 612 can fully fit the inner wall of the steel pipe 1 with a circular cross section, so the device can be applied to a steel pipe 1 with a rectangular cross section or a circular cross section.

[0034] In a further preferred embodiment of the present invention, Figure 5 As shown, the extrusion piece 61 is fixedly connected to the corresponding sliding column 5 by bolts.

[0035] In this embodiment, the staff can replace the extrusion member 61 with bolts, replace the arc plate 612 with the flat plate 611, or replace the flat plate 611 with the arc plate 612, so as to support and reinforce the steel pipe 1 with a rectangular cross-section or a circular cross-section.

[0036] In a further preferred embodiment of the present invention, Figure 4As shown, the adjusting portion 11 includes two first screws 111 rotatably connected to the top of the first wedge block 7, and also includes two second screws 112 rotatably connected to the top of the second wedge block 8. The first screw 111 and the second screw 112 both pass through the top of the cylinder 4 and extend to above the cylinder 4, and the first screw 111 and the second screw 112 are both threadedly connected to the cylinder 4. A limiting portion 113 is provided in the lower half of the cylinder 4, and a third wedge block 114 is fixedly connected to one end of the sliding column 5 located in the cylinder 4.

[0037] In this embodiment, the side of the third wedge block 114 close to the first wedge block 7 or the second wedge block 8 is inclined, and the side wall of the third wedge block 114 fits with the side wall of the first wedge block 7 or the side wall of the second wedge block 8. The staff rotates the two first screws 111 to drive the first wedge block 7 to move downward, and the first wedge block 7 squeezes the two third wedge blocks 114, thereby driving the corresponding two sliding columns 5 to extend out of the cylinder 4 until the extrusion piece 61 fits with the inner wall of the steel pipe 1, and the clamping block 62 is inserted into the corresponding clamping groove 63. The staff rotates the two second screws 112 to drive the other two extrusion pieces 61 to fit with the inner wall of the steel pipe 1, thereby completing the installation of the device, and then pouring concrete into the steel pipe 1 to form a steel pipe concrete column.

[0038] The descending distances of the first wedge block 7 and the second wedge block 8 may be different, so the distances that the two pairs of sliding columns 5 extend out of the cylinder 4 may be different, so the internal length and width of the steel pipe 1 used in the device do not need to be the same.

[0039] In a further preferred embodiment of the present invention, Figure 4 As shown, the limiting portion 113 includes two first limiting rods 115 and two second limiting rods 116 fixedly connected to the inner bottom wall of the cylinder 4, the upper half of the first limiting rod 115 is slidably inserted into the lower half of the first wedge block 7, and the upper half of the second limiting rod 116 is slidably inserted into the lower half of the second wedge block 8.

[0040] In this embodiment, the first limiting rod 115 limits the first wedge block 7 so that the first wedge block 7 can only move vertically. The second limiting rod 116 limits the second wedge block 8 so that the second wedge block 8 can only move vertically.

[0041] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
