Description

Technical Field

[0001] The utility model relates to the technical field of steel structure beams, in particular to a spliced ​​steel structure beam. Background Art

[0002] Steel structure is a structure made of steel materials. It 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 and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings and other fields. Among them, steel structural beams are the most common structure in daily use.

[0003] For example, the existing patent announcement number CN220014202U provides a spliced ​​steel structure beam, which facilitates the operation of adjusting the splicing direction of the steel structure beam, improves the practicality of the device, and increases the safety and practicality of the device.

[0004] However, the device is only suitable for facilitating the operation of adjusting the splicing direction of steel structure beams, which improves the practicality of the device.

[0005] The existing spliced ​​steel structure beams are only convenient for splicing and adjusting the splicing direction. The splicing connection between the two beams is relatively simple, and the splicing strength is low, resulting in the splicing between the two beams being unstable and easy to break. At the same time, the splicing structure at both ends of the beam is not convenient for disassembly, replacement and installation, and cannot provide protection for both ends of the beam, which easily leads to damage to both ends of the beam and the need to replace the beam, which is wasteful and results in high losses. Utility Model Content

The second positioning hole 14 is aligned with the first positioning hole 4, and positioning pins 20 are inserted into the second positioning hole 14 and the first positioning hole 4. The two ends of the positioning pins 20 do not protrude from the second positioning hole 14, so that the splicing plate 5 is stably clamped in the second I-shaped groove 13, thereby making the splicing connection between the first splicing joint 11 and the second splicing joint 12 stable.

[0034] A reinforcement frame 7 is sleeved on the outside of the joint of the first splicing joint 11 and the second splicing joint 12. The reinforcement frame 7 is a rectangular frame structure. Before the first beam body 1 and the second beam body 2 are spliced, the reinforcement frame 7 is sleeved on the outside of the first splicing joint 11 or the second splicing joint 12. After the first splicing joint 11 and the second splicing joint 12 are spliced ​​through the splicing plate 5, the reinforcement frame 7 is sleeved on the outside of the joint of the first splicing joint 11 and the second splicing joint 12 to reinforce the splicing of the first splicing joint 11 and the second splicing joint 12.

[0035] A first connecting hole 23 is opened at the top of the reinforcement frame 7. The first connecting hole 23 is a threaded hole structure. A tightening bolt 8 passes through the inside of the first connecting hole 23. The inner ends of the tightening bolt 8 respectively support the first splicing joint 11 and the second splicing joint 12 to keep the reinforcement frame 7 stably sleeved on the outer side of the joint of the first splicing joint 11 and the second splicing joint 12.

During the splicing process of the first beam body 1 and the second beam body 2, the first splicing joint 11 is plugged and connected with the second splicing joint 2 through the splicing plate 5, and is positioned and stabilized by the positioning pin 20.

[0042] At the same time, the reinforcement frame 7 is pre-sleeved on the outside of the first splicing joint 11 or the second splicing joint 12. After the first splicing joint 11 and the second splicing joint 12 are spliced ​​and connected, the reinforcement frame 7 is sleeved on the outside of the first splicing joint 11 and the second splicing joint 12 to reinforce and stabilize the splicing connection between the two, thereby improving the strength and stability of the splicing connection between the first splicing joint 11 and the second splicing joint 12, and further improving the strength and stability of the splicing between the first beam body 1 and the second beam body 2, which is not easy to break and disassemble.
