[0022] ​The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a 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 making creative efforts are within the scope of protection of the present invention.

[0023] like Figures 1 to 3 As shown, a typical embodiment of the present invention provides a rectangular column reinforcement steel buckle, including a fastener 1 and a pin 2, the fastener 1 includes an adjustable pin hole end 5 and a buckling end 6, the adjustable pin hole end 5 is provided with two rows of pin holes 3, and the two rows of pin holes 3 are staggered. By cooperating with the pin holes 3 at different positions of the pin 2, it can be adapted to columns of different sizes. The buckling end 6 is formed by bending to form a sleeve groove 4 for sleeved on the adjustable pin hole end 5, the force-bearing side of the pin 2 is set at a right angle, and the pin 2 is set to a shape with a larger upper end and a smaller lower end.

[0024] After applying this embodiment, only two structures, namely the fastener 1 and the pin 2, are needed to reinforce the rectangular column formwork. Compared with the traditional screw rod and steel pipe reinforcement, it is faster and more convenient, can save construction time and reduce costs; the stronger rigidity can eliminate the use of screw rods and steel pipes in traditional reinforcement methods, and reduce the investment in auxiliary materials; without the tie rod holes after the column is formed, the forming quality is greatly improved, and the apparent quality of the concrete is significantly improved.

[0025] A pin 2 with a right angle on one side is used for reinforcement. After being fastened, the fastener 1 has a strong restraint on the formwork, which can reduce the problems of form expansion and column distortion in traditional construction. Compared with traditional reinforcement methods, there is less screw rod running through the inside of the column during pouring, which avoids the screw rod loosening and falling off due to pouring vibration.

[0026] The fastener 1 comprises a plate portion and flanges disposed on either side of the plate portion. The force-bearing side of the latch 2 contacts the flanges, and the pin hole 3 is formed in the plate portion. The flanges increase the contact surface between the fastening end 6 and the right-angled edge of the latch 2 after the latch 2 is inserted into the pin hole 3, improving the stability of the latch 2 and ensuring that the latch 2 is in a vertically downward position, thereby enhancing the fastening effect.

[0027] As one of the specific preferred embodiments, the fastener 1 is formed by bending a narrow-flange I-beam, so that the fastener 1 has high strength and a long service life and can be reused. Specifically, in one relatively specific embodiment, the fastener 1 is made of a No. 10 narrow-flange I-beam, and the pin hole 3 is formed in the web of the narrow-flange I-beam. The bolt 2 is a straight-angle trapezoidal steel plate. Specifically, in one relatively specific embodiment, the bolt 2 is made of a 10 mm thick steel plate, and the bolt 2 has high strength and is not easy to be damaged. The large head of the bolt 2 faces upward, and the small head faces downward. The straight-angle side of the bolt 2 faces the force direction, so that the bolt 2 is prevented from sliding or loosening.

[0028] The upper and lower inner walls of the sleeve groove 4 are parallel. When the adjustable pin hole end 5 of the fastener 1 is sleeved in the sleeve groove 4, the upper and lower inner walls of the sleeve groove 4 are respectively in contact with the upper and lower sides of the other fastener 1, so that the stability of the two fasteners 1 after being connected is improved, and the reinforcing effect on the formwork is improved.

[0029] The width of the pin hole 3 is matched with the thickness of the bolt 2, and the length of the pin hole 3 is less than the width of the larger end of the bolt 2. The effective cooperation of the bolt 2 and the pin hole 3 can improve the stability of the fastener in reinforcing the formwork.

[0030] When the bolt 2 is inserted into the pin hole 3, the force receiving surfaces of the bolt 2 located on the upper and lower sides of the pin hole 3 are respectively in contact with the upper and lower sides of the sleeve groove 4. After the formwork is reinforced, the upper and lower ends of the bolt 2 are both under stress, so that the bolt 2 is more balanced as a whole, and the reinforcing effect and stability on the formwork are improved.

[0031] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
