Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, specifically to a quick-fastening connector device for steel structure installation. Background Technology

[0002] In the field of steel structure installation engineering, steel structures are widely used in various large-scale buildings, bridges, industrial plants, and other projects due to their high strength, light weight, and good seismic performance. However, the installation process of steel structures involves many complex steps, among which the fastening of connectors is a key step to ensure the overall stability and safety of the steel structure.

[0003] Traditional steel structure fastening methods primarily rely on bolt connections and welding. While bolt connections offer the advantage of relatively convenient installation and disassembly, in practice, they require a significant amount of manual labor to tighten each bolt individually. This is not only inefficient but also makes it difficult to ensure consistent tightening torque for each bolt, potentially leading to weak connections and impacting the lifespan and safety of the steel structure. Furthermore, bolted connections are prone to loosening over long-term use, necessitating regular inspection and maintenance. Welded connections, while providing a more robust connection, require sophisticated welding techniques and skilled welders. The heat generated during welding can adversely affect the material properties of the steel structure, leading to localized stress concentrations and deformation. Moreover, once welded connections are completed, disassembly is difficult, hindering future modifications and repairs of the steel structure. Utility Model Content

[0021] Working principle: Place the mounting base plate 3 at the designated position on the steel structure installation end. Utilize the evenly spaced through holes along the top edge of the mounting base plate 3, and securely fix the mounting base plate 3 to the steel structure using bolts or other fasteners. At this time, the bottom end of the mating block 2 is fixed at the center of the top surface of the mounting base plate 3, and its top locking block 20 is aligned with the bottom locking hole 19 at the center of the bottom end of the main support block 1. Place the main support block 1 downwards, allowing the locking block 20 to engage with the bottom locking hole 19, achieving initial docking between the main support block 1 and the mating base block 2. Then, symmetrically thread the positioning screws 4 into the side screw holes 21 on both sides of the main support block 1, and insert the extended end of the positioning screws 4 into the inside of the bottom locking hole 19, pressing against the outer edge of the locking block 20 to further secure the connection between the main support block 1 and the mating base block 2, preventing loosening. Vertically engage the side locking block 13 at one end of the connecting block 9 into the vertically grooved slots 5 on both sides of the main support block 1, so that the connecting block 9 is horizontally engaged with the side opening end of the vertical groove 5.

Then, symmetrically insert the fixing screws 8 into the through holes 12, and extend the threads to fix them to the inner side of the top of the fixing screw holes 11, thereby fixing the blocking plate 7 and the connecting block 9. Insert the steel structure end to be connected into the horizontally opened socket groove 16 at the end of the connecting block 9 away from the main support block 1. At this point, the extrusion teeth 18, located within the symmetrically opened limiting grooves 17 on the top and bottom surfaces of the extrusion sleeve groove 16 on the outer side of the steel structure end, exert a certain frictional and clamping force on the steel structure end under the extrusion action. Finally, the steel structure end is further fixedly connected to the connecting block 9 by using screws through the evenly opened fixing holes 14 on the side of the connecting block 9 to ensure a firm connection. Simultaneously, the extrusion screw 10, symmetrically threaded on the top and bottom surfaces of the connecting block 9, can be rotated. The extrusion screw 10 is threaded through the inner side of the through screw hole 15, and its extended end is inserted into the center of one side of the extrusion teeth 18, further adjusting the extrusion force of the extrusion teeth 18 on the steel structure end and enhancing the connection effect.
