Technical Field

[0001] The present application relates to the technical field of steel structure reinforcement, and in particular to a reinforced steel structure reinforcement device. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. The components or parts are usually connected by welds, bolts or rivets. Although steel has high strength, good toughness and good seismic performance. However, when the steel is installed, especially when the steel beam is strung between two steel columns, its center of gravity sags and it is easy to deflect. The connection between the steel beam and the steel column is also prone to deformation. Therefore, when the steel beam is installed, welded ribs are usually added to increase the connection area and increase the tightness of the connection. However, the point of action on the beam is still relatively small, the connection strength is still insufficient, and it is still easy to loosen and deform in the later stage.

[0003] To this end, the present application provides a reinforced steel structure reinforcement device, providing a reinforcement device with stronger connection strength. Utility Model Content

[0023] The following is a combination of the appended examples of the present application Figure 1-6 , the technical solutions in the embodiments of the present application are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0024] In Example 1, a traditional steel structure generally includes a steel column 1, steel beams, and trusses. Extension plates are welded to the ends of the steel beams and trusses, and fastened to the side walls of the steel columns 1 using bolts and other fasteners. This increases the connection area with the steel columns 1 and enhances the connection strength. However, the center of the steel beams and trusses deviates from the steel columns 1, making them prone to sinking and deformation, which affects the tightness and stability of the connection.

[0025] In order to solve the problems existing in the prior art, the present embodiment provides a reinforced steel structure reinforcement device, including a steel column 1, a crossbeam 2 is fastened to the side wall of the steel column 1, two pulling steel ropes 3 are symmetrically fastened to the crossbeam 2 along the width direction, and the two pulling steel ropes 3 are fastened to the suspended ends with studs 4. The side wall of the steel column 1 is provided with a through hole corresponding to the stud 4, and a self-locking nut 5 is screwed on one end of the stud 4 through the through hole, and the self-locking nut 5 is against the side wall of the steel column 1 on the side away from the pulling steel rope 3.

[0026] Principle details of this embodiment:

[0027] A reinforced steel structure reinforcement device includes a pulling wire rope 3, and two sets of pulling wire ropes 3 are provided between each crossbeam 2 and the steel column 1. The two sets of pulling wire ropes 3 are symmetrically arranged along the width direction of the crossbeam 2. One end of the pulling wire rope 3 is fastened to the surface of the crossbeam 2, and the other end is fastened to a stud 4. The side wall of the steel column 1 is provided with a through hole corresponding to the stud 4. The end of the steel column 1 facing away from the pulling wire rope 3 passes through the through hole, and the end of the stud 4 passing through the through hole is screwed with a self-locking nut 5. The self-locking nut 5 rests on the side wall of the steel column 1 facing away from the pulling wire rope 3. The thread between the self-locking nut 5 and the stud 4 has a self-locking characteristic to prevent the thread from slipping and affecting the pulling stability.

[0028] In this embodiment, the steel column 1 is generally divided into an I-beam structure, a square tube structure, and a round tube structure. Compared to the stud 4 passing through these types of steel column 1 structures, the stud 4 needs to pass through both side walls of the steel column 1 in order to pass through the steel column 1 and be fastened and installed by nuts. Therefore, in this embodiment, through holes are provided on both side walls of the steel column 1 and the axes of the through holes on both sides are aligned. When the distance between the two side walls of the steel column 1 is greater than the length of the stud 4, the diameters of the through holes on both sides are the same; when the distance between the two side walls of the steel column 1 is less than the length of the stud 4, the diameter of the through hole facing the pulling wire rope 3 is greater than the diameter of the stud 4, which facilitates the insertion and installation of the stud 4. Preferably, the through hole is rounded to avoid damage when the pulling wire rope 3 passes through the through hole.

[0029] In this embodiment, the pulling steel wire rope 3 and the stud 4 are fixed by welding via a cable clamp; the connection between the pulling steel wire rope 3 and the crossbeam 2 is through welding.

[0030] According to the above technical solution:

[0031] During use, one end of the pulling wire rope 3 is fastened to the end face of the beam 2, and the other end is fastened to the steel column 1 through the cooperation of the stud 4 and the self-locking nut 5, thereby increasing the pulling force on the end of the beam 2, reducing the drop of the center of the beam 2 to the connection between the beam 2 and the steel column 1, improving the connection tightness between the beam 2 and the steel column 1, and increasing the connection strength between the beam 2 and the steel column 1. The pulling force of the pulling wire rope 3 on the beam 2 can be adjusted by screwing the self-locking nut 5, which can be applied to the reinforcement of the beam 2 in different states before and after deformation.

[0032] Example 2, in a further embodiment of this solution, refer to the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 As shown, the pulling wire ropes 3 between different cross beams 2 and the same steel column 1 are staggered to avoid interference in the installation of the studs 4 between different cross beams 2 and steel columns 1.

[0033] In a further embodiment of this solution, the pulling wire rope 3 passes through the crossbeam 2 and is welded to the crossbeam 2 at its contact point. This allows the pulling wire rope 3 and the crossbeam 2 to form a single unit. This makes it difficult to replace the pulling wire rope 3 after fatigue damage. Therefore, in this embodiment, the pulling wire rope 3 is secured to a stud 4 at one end and a hook 6 at the other end. A hook 7 is screwed onto the crossbeam 2 to engage with the hook 6.

[0034] Principle details of this embodiment:

[0035] The pulling wire rope 3 is welded to a stud 4 at one end and a hook 6 at the other end. The crossbeam 2 is provided with a threaded hole 8, into which a hook 7 is screwed. The hook 6 is attached to the hook 7. The hook 6 is provided with a release mechanism. If the pulling wire rope 3 breaks due to fatigue, the self-locking nut is removed, the stud 4 is removed from the steel column 1, and the hook 6 is then loosened. The pulling wire rope 3 can then be removed and replaced with a new one.

[0036] Preferably, a self-locking nut is also screwed onto the threaded end of the hanging ear 7 , and the nut rests against the bottom end of the beam 2 to increase the connection strength between the hook 6 and the beam 2 .

[0037] Embodiment 4, in a further embodiment of this solution, the threaded hole 8 is unique, and the position of the hook 6 is unique, so that the connection point between the pulling wire rope 3 and the beam 2 is fixed, and the pulling of the beam 2 in different complete states cannot be used. Therefore, in this solution, the beam 2 is provided with a plurality of threaded holes 8 that are threadedly engaged with the lugs 7 near one end of the steel column 1, and the plurality of threaded holes 8 are arranged at intervals along the length direction of the beam 2. By replacing the pulling wire rope 3 of different lengths or adjusting the length of the stud 4 passing through the steel column 1, the different connection position relationships between the pulling wire rope 3 and the beam 2 can be adjusted to suit different usage situations and improve the flexibility of equipment use.

[0038] Example 5, a further embodiment of the present invention, in order to reduce the influence of the sagging deformation of the center of the beam 2 on the connection strength. In this embodiment, a steel cable 9 is arranged between two adjacent steel columns 1, and the steel cable 9 is located at the center of the steel column 1 without interfering with the pulling wire rope 3. Both ends of the steel cable 9 pass through the steel column 1 and are fastened to the beam 2 on the other side of the steel column 1. A plurality of cables are fastened and installed on the steel cable 9 along the length direction through rigging, and the bottom end of the cable is fastened and installed to the surface of the beam 2. Through the cooperation between the steel cable 9 and the plurality of cables, the upward traction force of the beam 2 to resist gravity is increased, thereby reducing the deformation probability of the beam 2 and delaying the deformation time of the steel structure.

[0039] In a further embodiment of this solution, the cable pulling wire rope 3 comprises a rigging system, which is connected to the crossbeam 2. Two lifting wire ropes 10 are symmetrically mounted on the rigging system, and the upper ends of the two lifting wire ropes 10 are symmetrically fastened to the steel cable 9. The triangular structure provides greater stability.
