Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, and in particular to a high-strength and stable steel structure. Background Technology

[0002] Steel structures are structures made of steel materials and are 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. Rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are used. The components or parts are usually connected by welds, bolts or rivets. Due to its light weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings, bridges and other fields. Steel structures are prone to rust, so they generally need to be derusted, galvanized or painted, and require regular maintenance.

[0003] However, in the existing technology, the beams and columns of the steel structure are fixed by angle iron, bolts or welding. The weight is borne by the beams and the connectors at the ends of the beams. The load-bearing capacity of the beams and the connectors at the ends of the beams is limited. They are prone to breakage under pressure for a long time, which affects the stability of the steel structure. Utility Model Content

[0004] The technical problem this utility model aims to solve is that the beams and columns of the steel structure are fixed by angle iron, bolts or welding, and the weight is borne by the connecting parts at the ends of the beams. However, the load-bearing capacity of the connecting parts at the ends of the beams is limited, and they are prone to breakage under pressure for a long time, which affects the stability of the steel structure.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] A high-strength and stable steel structure includes a steel column. Both sides of the steel column are bolted to connecting angle irons. A steel beam is bolted to the upper surface of the connecting angle irons. The end of the steel beam is flush with the side of the steel column. Two symmetrically distributed through-slots are provided on both sides of the steel column. Four symmetrically distributed connecting slots are provided at the end of the steel beam. A first connecting cable is fixed to the upper surface of the steel beam, and a second connecting cable is fixed to the upper surface of the connecting angle irons. The first and second connecting cables pass through the through-slots and enter the inner side of the steel column. A counterweight is slidably provided inside the steel column. The ends of the first and second connecting cables are fixed to the top of the counterweight.

[0007] Preferably, the counterweight has multiple parallel vertical grooves on both sides, and friction strips are engaged inside the grooves.

[0008] Preferably, the friction strip is made of rubber and its outer surface is in frictional contact with the inner wall of the steel structure column. When the friction strip is located inside the strip groove, it is in a compressed state.

[0009] Preferably, multiple support rods are fixed to the inner side of the steel structure column, and the support rods are respectively located below the first connecting steel cable and the second connecting steel cable.

[0010] Preferably, both sides of the slot are provided with fixing strips, the fixing strips are fixed to the steel structure column, and two supporting cylindrical members are provided between the two fixing strips.

[0011] Preferably, a rotating shaft is provided inside the supporting cylindrical member, and the supporting cylindrical member is rotatably connected to the fixing strip through the rotating shaft, and the two supporting cylindrical members are respectively located below the first connecting steel cable and the second connecting steel cable.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] By using counterweights on the inside of the steel structure columns to pull the first and second connecting steel cables, the first connecting steel cable exerts an upward pulling force on the steel structure beam and the second connecting steel cable exerts an upward pulling force on the connecting angle iron. This reduces the pressure of the steel structure beam on the connecting angle iron and increases the load-bearing capacity of the steel structure beam. The increased load-bearing capacity of the steel structure beam simultaneously enhances the load-bearing performance of the entire steel structure, making the overall steel structure stronger and more stable, and safer to use.

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] like Figure 1 As shown, a high-strength and stable steel structure includes a steel structural column 1. Both sides of the steel structural column 1 are bolted to connecting angle irons 3. A steel structural beam 2 is bolted to the upper surface of the connecting angle irons 3. The end of the steel structural beam 2 is fitted against the side of the steel structural column 1. Two symmetrically distributed through slots 7 are provided on both sides of the steel structural column 1. Four symmetrically distributed connecting slots 8 are provided at the end of the steel structural beam 2. A first connecting steel cable 5 is fixed to the upper surface of the steel structural beam 2, and a second connecting steel cable 6 is fixed to the upper surface of the connecting angle irons 3. Steel cable 5 and second connecting steel cable 6 pass through the inside of slot 7 and enter the inside of steel structure column 1. A counterweight 4 is slidably provided on the inside of steel structure column 1. The ends of the first connecting steel cable 5 and second connecting steel cable 6 are fixed to the top of the counterweight 4. The counterweight 4 on the inside of steel structure column 1 pulls the first connecting steel cable 5 and second connecting steel cable 6, so that the first connecting steel cable 5 exerts an upward pulling force on the steel structure beam 2 and the second connecting steel cable 6 exerts an upward pulling force on the connecting angle iron 3, thereby reducing the pressure of the steel structure beam 2 on the connecting angle iron 3 and increasing the load-bearing capacity of the steel structure beam 2.

[0021] As a preferred technical solution in this embodiment, such as Figure 2 and Figure 3 As shown, multiple support rods 11 are fixed on the inner side of the steel structure column 1. The support rods 11 are located below the first connecting steel cable 5 and the second connecting steel cable 6, respectively. The support rods 11 ensure that the ends of the first connecting steel cable 5 and the second connecting steel cable 6 connected to the counterweight block 4 remain vertically downward.

[0022] Both sides of the slot 7 are provided with fixing strips 10, which are fixed to the steel structure column 1. Two supporting cylindrical members 9 are provided between the two fixing strips 10. A rotating shaft is provided inside the supporting cylindrical member 9. The supporting cylindrical member 9 and the fixing strip 10 are rotatably connected by the rotating shaft. The two supporting cylindrical members 9 are located below the first connecting steel cable 5 and the second connecting steel cable 6, respectively. The supporting cylindrical members 9, together with the supporting rod 11, support the first connecting steel cable 5 and the second connecting steel cable 6, so as to avoid direct friction between the first connecting steel cable 5 and the second connecting steel cable 6 and the steel structure column 1, and to prevent the first connecting steel cable 5 and the second connecting steel cable 6 from being worn or broken due to friction.

[0023] As a preferred technical solution in this embodiment, such as Figure 4As shown, multiple parallel vertical grooves are provided on both sides of the counterweight 4. Friction strips 12 are engaged inside the grooves. The friction strips 12 are made of rubber and their outer surfaces are in frictional contact with the inner wall of the steel structure column 1. When the friction strips 12 are located inside the grooves, they are under compression. The friction strips 12 increase the frictional resistance between the counterweight 4 and the steel structure column 1. When the end of the steel structure beam 2 and the connecting angle iron 3 are pressed downward, the pull of the first connecting steel cable 5 and the second connecting steel cable 6 on the counterweight 4 will not cause the counterweight 4 to slide upward easily. At this time, the first connecting steel cable 5 and the second connecting steel cable 6 provide support for the steel structure beam 2 and the connecting angle iron 3, thereby improving the load-bearing capacity of the steel structure beam 2 and the connecting angle iron 3.

[0024] Working principle: First, use bolts to assemble the connecting angle iron 3 with the steel structure column 1. After assembly, the end of the steel structure beam 2 is then overlapped on the upper surface of the connecting angle iron 3, and the connecting angle iron 3 and the steel structure beam 2 are assembled with bolts. At this time, it is necessary to ensure that the second connecting steel cable 6 passes through the inside of the connecting groove 8 at the end of the steel structure beam 2. Then, the first connecting steel cable 5 and the second connecting steel cable 6 pass over the supporting cylindrical member 9 and through the through slot 7 into the inside of the steel structure column 1. After the ends of the first connecting steel cable 5 and the second connecting steel cable 6 enter the inside of the steel structure column 1, they overlap on the outer surface of the corresponding support rod 11. This causes the ends of the first connecting steel cable 5 and the second connecting steel cable 6 to point downwards and be fixed to the counterweight 4. At this time, the counterweight 4 is suspended in the air due to gravity through the first connecting steel cable 5 and the second connecting steel cable 6. The counterweight 4 then exerts an upward pulling force on the steel structure beam 2 and the connecting angle iron 3 through the first connecting steel cable 5 and the second connecting steel cable 6. When the steel structure beam 2 and the connecting angle iron 3 are under pressure, part of the pressure is borne by the first connecting steel cable 5 and the second connecting steel cable 6, increasing the load-bearing capacity of the steel structure beam 2 and the connecting angle iron 3, making the overall strength of the steel structure higher and more stable, and safer to use.

For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
