DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and are not used to limit the scope of application of the present utility model. Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0025] Reference Figure 1-Figure 7 A reinforcement structure for a bending steel member comprises two U-shaped reinforcement steel plates 1, two connecting plates 2, a plurality of bolts 3 and a plurality of nuts 4 respectively threadedly sleeved on the plurality of bolts 3. The surfaces of the reinforcement steel plates 1 and the connecting plates 2 are provided with a plurality of through openings for the bolts 3 to pass through, and a reinforcement opening 5 for the bending steel member to enter is formed between the two reinforcement steel plates 1 and the two connecting plates 2.

[0026] A spring rod 6 is fixedly installed on the side wall of the reinforcing steel plate 1, and a mounting plate 7 is fixedly installed on one end of the spring rod 6 away from the reinforcing steel plate 1. Both ends of the mounting plate 7 are fixedly installed with U-shaped clamping seats 8, which are used to clamp two bolts 3 and two nuts 4 located on the same horizontal line.

[0027] First, the bending steel member to be reinforced is tightly clamped between the two reinforcing steel plates 1, and then the two connecting plates 2 are respectively pressed against the upper and lower surfaces of the two reinforcing steel plates 1, and then the two spring rods 6 are controlled to stretch so that the multiple bolts 3 are respectively passed through the multiple overlapping through-holes, and then the multiple nuts 4 are respectively threadedly sleeved on the multiple bolts 3 until the surfaces of the multiple bolts 3 are all pressed against the surfaces of the connecting plates 2, and the surfaces of the multiple nuts 4 are all pressed against the surfaces of the reinforcing steel plates 1, and then the splicing and fixation of the two reinforcing steel plates 1 and the two connecting plates 2 can be completed, and at this time, the two spring rods 6 are loosened, and the multiple clamping seats 8 will quickly move and reset under the elastic potential energy of the two spring rods 6, and the multiple bolts 3 and the multiple nuts 4 are here. When the bolts 3 and nuts 4 are in contact with each other, the bolts 3 and nuts 4 will be in contact with each other, and the distance between the bolts 3 and nuts 4 will be limited by the clamping seat 8 and cannot be changed. This can limit the relative rotation of the bolts 3 and nuts 4, and avoid the relative rotation of the bolts 3 and nuts 4 after long-term use, which will cause the joint between the reinforced steel plate 1 and the connecting plate 2 to loosen, thereby improving the stability of the reinforced bending steel member. By controlling the stretching of the spring rod 6, the clamping seat 8 is moved away from the reinforced steel plate 1, until the multiple bolts 3 and the multiple nuts 4 are removed from the clamping seat 8, and the restriction on the bolts 3 and nuts 4 can be released.

[0028] A first limiting component is provided on the side wall of the reinforced steel plate 1, and the first limiting component is used to limit the stretching of the spring rod 6. The first limiting component includes an L-shaped limiting rod 9. A mounting groove is vertically opened on the side wall of the reinforced steel plate 1, and a rotating shaft is horizontally rotatably installed in the mounting groove, and the limiting rod 9 is fixedly sleeved on the rotating shaft.

[0029] When multiple clamping seats 8 respectively have a limiting effect on multiple bolts 3 and multiple nuts 4, the two limiting rods 9 can be controlled to rotate until the two limiting rods 9 are respectively rotated to abut against the two clamping seats 8 located below. At this time, the two limiting rods 9 will be in a horizontal state, and the surfaces will be in contact with the clamping seats 8, which can limit the lateral movement of the clamping seats 8, that is, limit the stretching of the spring rod 6, and prevent the spring rod 6 from being stretched due to the influence of external vibration force, thereby moving the clamping seat 8 laterally, so that the limiting effect of the clamping seat 8 on the bolts 3 and nuts 4 disappears.

[0030] A circular opening is provided on the surface of the mounting plate 7, and a second limiting component is provided in the circular opening. The second limiting component is used to limit the stretching of the spring rod 6. The second limiting component includes a rotating rod 10 rotatably installed in the circular opening and two mounting blocks 11 symmetrically fixedly installed on the surface at one end of the rotating rod 10. A hollow cylinder 12 with one end designed to be closed is fixedly installed on the side wall of the reinforcement steel plate 1. The closed end of the hollow cylinder 12 is provided with a first through-opening 13 for the end of the rotating rod 10 to pass through, and the closed end of the hollow cylinder 12 is provided with a second through-opening 14 for the two mounting blocks 11 to pass through. The rotating rod 10 is fixedly connected to the mounting plate 7 through an elastic component. The elastic component includes a torsion spring 15 sleeved on the rotating rod 10. A fixing block is fixedly installed at one end of the rotating rod 10, and both ends of the torsion spring 15 are fixedly connected to the fixing block and the mounting plate 7 respectively.

[0031] When the plurality of clamping seats 8 respectively limit the plurality of bolts 3 and the plurality of nuts 4, and the two limiting rods 9 respectively limit the two clamping seats 8 located below, at this time, the two rotating rods 10 are fixedly installed with one end of the two mounting blocks 11, which will be located in the two hollow cylinders 12 respectively, and the plurality of mounting blocks 11 will not correspond to the positions of the plurality of second through-holes 14, so that the rotating rod 10 cannot move in the direction away from the reinforced steel plate 1 at this time, and can also limit the stretching of the spring rod 6, and when it is necessary to release When limiting, it is necessary to rotate the rotating rod 10 until the two mounting blocks 11 correspond to the positions of the two second through-holes 14 respectively. At this time, the obstruction of the hollow tube 12 to the rotating rod 10 disappears. When the control spring rod 6 is stretched, the rotating rod 10 and the two mounting blocks 11 will be moved out of the first through-hole 13 and the two second through-holes 14 respectively. When the rotating rod 10 is released, the rotating rod 10 will quickly rotate and reset under the elastic potential energy of the torsion spring 15, and the positions of the two mounting blocks 11 and the two second through-holes 14 will no longer correspond.

[0032] The two reinforced steel plates 1 are bonded with an anti-skid layer on the sides close to each other. The material of the anti-skid layer is rubber. The rubber anti-skid layer has good elasticity and viscosity, which can increase the friction between the reinforced steel plate 1 and the contact surface of the bending steel member, and at the same time avoid wear on the surface of the bending steel member due to pressure reinforcement.

[0033] In the utility model, firstly, the bending steel member to be reinforced is tightly clamped between two reinforcing steel plates 1, and then the two connecting plates 2 are respectively pressed against the upper and lower surfaces of the two reinforcing steel plates 1, and then the two spring rods 6 are controlled to stretch so that the multiple bolts 3 are respectively passed through the multiple overlapping through-holes, and then the multiple nuts 4 are respectively threadedly sleeved on the multiple bolts 3 until the surfaces of the multiple bolts 3 are all pressed against the surfaces of the connecting plates 2, and the surfaces of the multiple nuts 4 are all pressed against the surfaces of the reinforcing steel plates 1, and then the splicing and fixing of the two reinforcing steel plates 1 and the two connecting plates 2 can be completed, and at this time, the two spring rods 6 are loosened, and the multiple The clamping seat 8 will quickly move and reset under the elastic potential energy of the two spring rods 6. At this time, multiple bolts 3 and multiple nuts 4 will be respectively located in multiple clamping seats 8, and the upper surface of the bolt 3 and the lower surface of the nut 4 will respectively abut against the upper and lower surfaces inside the clamping seat 8. At this time, the distance between the bolt 3 and the nut 4 is limited by the clamping seat 8 and cannot change. This can limit the relative rotation of the bolt 3 and the nut 4, thereby preventing the bolt 3 and the nut 4 from rotating relative to each other after long-term use, thereby causing the joint between the reinforced steel plate 1 and the connecting plate 2 to become loose, thereby improving the stability of the reinforced bending steel member.

[0034] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
