[0002] In steel structure engineering, steel components are structural parts made of steel with a certain geometric shape and load-bearing capacity. Among them, steel columns are one of the most common steel components, and their connections are mostly fixed by flanges and screw and nut fasteners.

[0003] Existing steel columns bear various complex loads, such as deadweight, wind load, earthquake load, etc. After long-term use and under the action of stress, it is easy to cause the screws and nuts to rotate relative to each other, resulting in loosening of the flange connection, affecting the fixing strength and posing certain safety hazards. Utility Model Content

[0004] The purpose of the utility model is to solve the following shortcomings in the prior art: the existing steel columns are subjected to various complex loads, such as deadweight, wind load, earthquake load, etc., and after long-term use and under the action of stress, the screws and nuts are easily caused to rotate relative to each other, resulting in loosening of the flange connection, affecting the fixing strength, and posing certain safety hazards. A steel member reinforcement structure for steel structure engineering is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0023] The terms such as "up", "down", "left", "right", "middle" and "one" cited in the utility model are only for the convenience of clear description, and are not used to limit the scope of the utility model. The change or adjustment of the relative relationship is also considered as the scope of the utility model without substantial change of the technical content.

[0024] Referring to Figure 1-Figure 5 A steel member reinforcing structure for steel structure engineering, comprising two steel member columns 1, a plurality of locking screws 4 and a plurality of locking nuts 5 respectively threadedly sleeved on the plurality of locking screws 4, one end of the steel member column 1 is fixedly sleeved with a flange plate 2, a plurality of threaded holes 3 for inserting the plurality of locking screws 4 are circumferentially formed on the surface of the flange plate 2, and a plurality of rectangular holes 6 corresponding to the plurality of threaded holes 3 are circumferentially formed on the side wall of the flange plate 2.

[0025] The two flange plates 2 are reinforced and connected through auxiliary locking components, the auxiliary locking components comprise a plurality of U-shaped connecting blocks 7, two center-symmetric mounting blocks 8 are fixedly installed on the inner wall of the connecting block 7, a triangular locking block 10 is fixedly installed on the surface of the mounting block 8 through an expansion component, the expansion component comprises a spring rod 9, the two ends of the spring rod 9 are fixedly connected with the mounting block 8 and the locking block 10 respectively, and the rectangular hole 6 is provided with a locking groove 13 for inserting the locking block 10.

[0026] When connecting two steel component columns 1, first, the two flanges 2 at the ends of the two steel component columns 1 are abutted against each other, and the multiple threaded openings 3 are overlapped in pairs, and then the multiple locking screws 4 are respectively threadedly installed on the multiple overlapping threaded openings 3, and then the multiple locking nuts 5 are respectively threadedly sleeved on the multiple locking screws 4 and tightened to complete the connection of the two steel component columns 1. At this time, every two of the multiple rectangular openings 6 will overlap, and then the multiple connecting blocks 7 are respectively aligned with every two overlapping threaded openings 3 and pushed in. The two side surfaces inside the connecting block 7 will respectively abut against the surfaces of the two flanges 2, thereby clamping the flanges 2, and at the same time During the pushing process, the inclined surfaces of the two locking blocks 10 will respectively slide into contact with the walls of the two overlapping threaded openings 3. Under the action of the inclined surface pressure, the two spring rods 9 will shrink until they move to the inner wall of the connecting block 7 tightly against the side wall of the flange 2 and can no longer move. At this time, the two locking blocks 10 will respectively correspond to the positions of the two locking grooves 13 opened in the walls of the two overlapping rectangular openings 6. The pressing force exerted by the walls of the rectangular openings 6 on the locking blocks 10 disappears, and the two locking blocks 10 will quickly move and reset under the elastic potential energy of the spring rods 9, and be inserted into the two locking grooves 13 respectively, thereby completing the locking of the connecting block 7.

[0027] And because the two locking blocks 10 are centrally symmetrically arranged, even if one of the locking blocks 10 is accidentally moved out of the locking groove 13, the other locking block 10 is still located in the other locking groove 13, thereby still being able to lock the connecting block 7.

[0028] A rubber layer is bonded to the inner wall of the connecting block 7 , which can increase the friction between the inner wall of the connecting block 7 and the contact surface of the flange 2 .

[0029] The surface of the connecting block 7 is symmetrically provided with centrally symmetrical through openings 11 . A pull plate 12 is fixedly sleeved on the spring rod 9 . One end of the two pull plates 12 passes through the two through openings 11 respectively.

[0030] When the connection block 7 needs to be unlocked, the spring rod 9 can be controlled to retract by pulling the pull plate 12 from the outside until the two locking blocks 10 are respectively moved out of the two locking grooves 13 .

[0031] The surface of the pull plate 12 is bonded with an anti-slip layer made of rubber. The rubber anti-slip layer has good elasticity and viscosity, thereby increasing the friction between the pull plate 12 and the palm contact surface.

[0032] A rotation limiting component is provided on the surface of the connecting block 7, which is used to limit the rotation of the locking screw 4 and the locking nut 5. The rotation limiting component includes a circular first rotation limiting block 14 and a rectangular second rotation limiting block 15. The first rotation limiting block 14 and the second rotation limiting block 15 are respectively fixedly mounted on both sides of the connecting block 7 through a connecting rod 16.

[0033] When the connecting block 7 is installed, the surface of the first limiting block 14 will abut against the larger end of the locking screw 4, and the surface of the second limiting block 15 will abut against the surface of the locking nut 5, which can limit the movement of the locking nut 5 and the locking screw 4. Since the locking nut 5 and the locking screw 4 must move horizontally if they are to rotate, the movement of the locking nut 5 and the locking screw 4 is limited, which also indirectly limits the rotation of the locking nut 5 and the locking screw 4.

[0034] When the bolt 12 is tightened, the bolt 12 is tightened to the screw thread 3 of the fixing plate 1 and the fixing plate 1 is tightened.

[0035] 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.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
