Description

Technical Field

[0001] This utility model relates to the field of steel beam installation technology, and in particular to a splicing and assembly structure for large steel beams. Background Technology

[0002] In modern architecture, bridges, large factories, and steel structure projects, steel beams serve as primary load-bearing components, and the quality of their connection and splicing directly affects the safety and stability of the entire structure. To meet the demands of large-span and complex structures, it is typically necessary to splice and assemble multiple steel beam sections on-site or in the factory. Traditional steel beam splicing methods mostly employ welding or high-strength bolt connections.

[0003] Joints are often the weakest points in a steel beam structure. When the steel beam bears a large load, stress concentration easily occurs at the joints, leading to bending, deformation, or even cracking, severely affecting the structure's load-bearing capacity and service life. When dealing with steel beams of different thicknesses or cross-sectional dimensions, different connection devices often need to be customized, which not only increases manufacturing costs but also reduces construction efficiency. In addition, traditional connection methods involve cumbersome installation steps, requiring a large amount of on-site welding or precise hole alignment, resulting in long construction cycles and high technical requirements for operators.

Detailed Implementation

[0026] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0027] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a large steel beam splicing and assembly structure of this utility model.

[0028] like Figures 1-8 As shown, this utility model embodiment provides a large steel beam splicing and assembly structure, including a support pipe 100 to support two sets of spliced ​​steel beams. The support pipe 100 is connected and supported by connecting parts 400 on both sides, and the connection of the connecting parts 400 is further fastened by a fixing part 300 in the middle.

[0029] The support tube 100 includes a tube body 110 fitted onto the upper end of the steel beam. The upper end of the tube body 110 is evenly provided with adjusting screws 130 for clamping and locking the tube body 110 and the steel beam. The adjusting screws 130 are threadedly installed inside the threaded heads 120 provided on both sides of the tube body 110 and are installed through the tube body 110. The threaded heads 120 and the tube body 110 are fixedly connected.

[0030] After connecting and fixing the spliced ​​steel beams, the pipe body 110 is fitted onto the upper end of the spliced ​​steel beams on both sides. Then, the fixing part 300 is used to fix the connecting part 400, thereby connecting the support pipes 100 on both sides into a whole. This further supports the steel beams, improves their stability, prevents bending at the splice, significantly reduces the risk of bending or deformation of the steel beams under stress, and enhances the load-bearing capacity and safety of the structure. An adjusting screw 130 is also provided to adjust the internal height, allowing it to rotate within the threaded head 120 for adjustment. The height of the screw 130 is adjusted to clamp and secure the internal steel beams, facilitating the fixing of steel beams of different thicknesses. The height of the screw extending into the tube 110 can be freely controlled, thereby achieving clamping and securing of steel beams of different thicknesses. This improves the versatility and adaptability of the device, making it suitable for splicing various specifications of steel beams. The device adopts a modular design, and the support tube 100 can be directly fitted onto the upper end of the steel beam. Together with the fixing part 300 and the connecting part 400, the connection and fastening of the support structures on both sides can be quickly achieved, simplifying the installation process and improving construction efficiency.

[0031] The connecting part 400 includes a rod 410 for connection and support. One end of the rod 410 is movably connected to the connector 150 fixedly installed on the upper end of the tube 110 via a shaft connection. The upper end of the rod 410 is provided with a fixing head 440 for connecting the rod 410. The fixing part 300 connects and fixes the fixing heads 440 on both sides. By connecting the fixing heads 440 with the fixing part 300, the fixing heads 440 are fixed to prevent loosening and shaking.

[0032] The rod body 410 is arranged in two sections, with a double-ended screw 420 in the middle for adjusting the length of the rod body 410. A hexagonal adjusting head 430 is located in the middle of the double-ended screw 420 for adjusting the double-ended screw 420. Both ends of the double-ended screw 420 are threaded into the inner cavity of the rod body 410. By rotating the hexagonal adjusting head 430, the double-ended screw 420 is driven to rotate, so that the double-ended screw 420 rotates within the length of the rod body 410, thereby adjusting the length of the rod body 410. This allows for convenient adjustment according to different steel beam installation conditions, providing greater flexibility.

[0033] A baffle 140 is placed inside the tube body 110 to protect the inner end of the adjusting screw 130. The baffle 140 is placed against the steel beam, and the end of the adjusting screw 130 is arranged to abut against the baffle 140. When the adjusting screw 130 is being adjusted, the baffle 140 is placed inside, which increases the force-bearing area of ​​the end of the adjusting screw 130 when clamping, reduces local damage to the steel beam, and makes it more stable.

[0034] The fixing head 440 is movably inserted into the connecting plate 330 for connection. Both sets of fixing heads 440 are installed in the slots opened in the connecting plate 330, and both sides are fastened by nuts. The fixing head 440 can be fixed according to the situation and combined with the holes in the connecting plate 330, making connection and fixation convenient.

[0035] The connection between the two sets of steel beams is fixed by splicing plates 200. The splicing plates 200 are provided with four sets, and the bolt holes penetrating the connection of the steel beams are fixed by connecting bolts 210 to connect and fix the spliced ​​steel beams.

[0036] The fixing part 300 includes a support frame 310 that is positioned and installed by bolts and a horizontal plate 320 installed on one side of the support frame 310 for supporting the connecting part 400. The horizontal plate 320 is fitted and installed in close contact with the connecting plate 330. The support frame 310 further fixes the connecting plate 330 to make it stable and divides it into multiple sets of triangles, making it more stable.

[0037] Two sets of support frames 310 are provided, respectively set on both sides of the horizontal plate 320. The horizontal plate 320 is fixed to the support frame 310 by bolts. The connecting plate 330 is clamped by the horizontal plate 320 to prevent the connecting part 400 from rotating and shaking, thus making it more stable.

[0038] Furthermore, the horizontal plate 320 is set at the lower end of the connecting plate 330 and is fixed to the support frame 310 by bolts, providing unidirectional support for the connecting plate 330. The installation is relatively simple and easy to disassemble.

[0039] A traction pipe 500 can be installed at one end of the connecting part 400 of the support pipe 100. A connecting angle 510 can be set at the upper end of the traction pipe 500. The connecting part 400 and the traction pipe 500 are fixed by the connecting angle 510. The connecting angle 510 is fixed by bolts welded to the upper end of the traction pipe 500. When the steel beam is spliced ​​longitudinally and laterally, the steel beam can be traction supported by the connection part 400 set in the middle of the support pipe 100 and the traction pipe 500. This facilitates the assembly of the steel beam, improves stability, and has a wider range of applications.

[0040] The working principle of a large steel beam splicing and assembly structure is as follows: After the spliced ​​steel beams are connected and fixed, the pipe body 110 is fitted onto the upper end of the spliced ​​steel beams on both sides. Then, the connecting part 400 is fixed using the fixing part 300, thereby connecting the support pipes 100 on both sides into a whole. This further supports the steel beams, improves their stability, avoids bending at the splice, significantly reduces the risk of bending or deformation of the steel beams under stress, and enhances the load-bearing capacity and safety of the structure. An adjusting screw 130 is also provided to adjust the internal height, allowing it to be adjusted within the threaded head 120. The unit rotates to adjust the height of the adjusting screw 130, thereby clamping and securing the internal steel beams. This facilitates the fixing of steel beams of different thicknesses and allows for free control of the height of the screw extending into the tube 110. This enables clamping and securing of steel beams of varying thicknesses, improving the versatility and adaptability of the device. It is suitable for splicing various specifications of steel beams. The device adopts a modular design, allowing the support tube 100 to be directly fitted onto the upper end of the steel beam. Together with the fixing part 300 and the connecting part 400, it quickly achieves the connection and securing of the support structures on both sides, simplifying the installation process and improving construction efficiency.
