Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, specifically to a steel structure frame that can be quickly assembled and disassembled. Background Technology

[0002] Steel structures are widely used in industrial plants, large stadiums, high-rise buildings and other fields due to their advantages such as high strength, light weight and fast construction speed. Although high-strength bolt connections can be disassembled, they usually require precise pre-drilling of bolt holes on the components. The installation process requires high accuracy of the hole positions, which is cumbersome and time-consuming. Moreover, it is inefficient in applications such as temporary structures and exhibition stands that require frequent disassembly or dynamic adjustment. Utility Model Content

[0003] In view of the problems existing in the prior art, this utility model discloses a steel structure frame that can be quickly assembled and disassembled. The technical solution adopted includes I-beams and splicing holes, which are the steel structures used for splicing in this technical solution, that is, splicing vertical and horizontal I-beams. The specific structural parts include splicing studs, limiting plates, nuts, sleeves, inner protrusions, side bending rods, clamping installation structures and clamping plates. The front side of the I-beam has splicing holes, and the front and rear sides of the sleeve have screw holes. The splicing studs are fitted with the screw holes and pass through the splicing holes. Nuts are fitted on the protruding end of the front side. The sleeve is fitted onto the vertical I-beam, and the inner protrusion integrally formed on its left inner side abuts against the groove of the I-beam. The sleeve is fixed at a certain height by the aforementioned splicing studs and nuts. This height is the splicing height of the horizontal I-beam. The left and right sides of the sleeve are integrally formed with side bending rods. The side bending rods are provided with clamping installation structures and clamping plates are installed through them. The clamping plates clamp the horizontal I-beams.

[0004] As a preferred technical solution of this utility model, the right side of the sleeve frame has an opening groove, and the right side is fixed with side shafts on the front and rear sides of the opening groove respectively. A stud is rotatably installed (a shaft seat is vertically mounted on the right side of the sleeve frame, and the stud is supported in the mounting hole of the shaft seat by its smooth rod part and can rotate around its own axis. The stud is machined with a shoulder for positioning on one side of the axis, and the other side is axially limited by an elastic retaining ring installed at the end of the stud). The side plate is movably fitted with the side shaft and installed in conjunction with the stud. A locking block is fixed on the inner side of the side plate. The locking block is made of rigid material and can provide an adjustable tightening structure on the side to further lock the sleeve frame.

[0005] As a preferred technical solution of this utility model, the clamping installation structure includes a wing plate, a connecting shaft, a rotating shaft, a knob, and an L-shaped mounting plate. The wing plate is integrally formed on the side of the side bending rod. A connecting shaft is fixedly connected between the upper and lower wing plates on the front side. A rotating shaft is rotatably mounted on the lower wing plate on the rear side (specifically, the lower wing plate on the rear side has bearing mounting holes, and a rolling bearing, such as a deep groove ball bearing, is installed by press-fitting. The lower end of the rotating shaft is installed in the inner ring of the rolling bearing through an interference fit. An integrally formed shoulder is provided on the axial direction of the rotating shaft, which abuts against the upper end face of the inner ring of the rolling bearing to withstand downward axial force). The upper end of the shaft extends from the through hole on the upper wing plate and a knob is fixed at the extended end. The side of the shaft has symmetrical threaded grooves on the top and bottom. L-shaped mounting plates are movably fitted with the connecting shaft and installed in conjunction with the threaded grooves on the shaft. A connecting plate is fixed between the front and rear L-shaped mounting plates. Rotating the knob can drive the shaft to rotate. The symmetrical threaded grooves distributed on its outer side can move the L-shaped mounting plate with the connecting plate. The connecting plates close to each other clamp the steel structure. The distance between the inner walls of the vertical parts of the front and rear L-shaped mounting plates is consistent with the width of the steel structure to be spliced, that is, the front and rear walls of the horizontal I-shaped steel are in close contact with the inner walls of the vertical parts of the L-shaped mounting plates.

[0006] As a preferred technical solution of this utility model, the surface of the card is covered with a friction layer.

[0007] As a preferred technical solution of this utility model, an anti-slip groove is provided on the outer side of the knob.

[0008] The beneficial effects of this utility model are as follows: Through the cooperation of the sleeve frame, splicing studs, and nuts, horizontal and vertical I-beams can be quickly positioned and fixed. The clamping plates can be moved by simply rotating a knob, enabling rapid clamping or loosening of the horizontal I-beams, greatly improving construction efficiency. It is particularly suitable for temporary structures, display racks, and other scenarios requiring frequent disassembly or adjustment. The installation height of the sleeve frame on the vertical I-beam can be flexibly adjusted via the splicing studs, thus adapting to the installation of horizontal beams at different floor heights or locations. The clamping installation structure achieves stepless adjustment of the clamping plate spacing through threaded transmission, enabling it to adapt to I-beams of different specifications and sizes or other similar cross-sections, demonstrating strong versatility.

The technical solution adopted includes an I-beam 1, splicing hole 101, splicing stud 2, limiting piece 201, nut 3, sleeve frame 4, inner protrusion 5, side bending rod 10, clamping installation structure and clamping plate 16. The I-beam 1 has a splicing hole 101 on its front side. The sleeve frame 4 has screw holes on its front and rear sides. The splicing stud 2 is fitted with the screw holes and passes through the splicing hole 101. The nut 3 is fitted on the front protruding end. The sleeve frame 4 is fitted on the vertical I-beam 1. The inner protrusion 5 integrally formed on its left inner side abuts against the groove of the I-beam 1. The side bending rod 10 is integrally formed on the left and right sides of the sleeve frame 4. The clamping installation structure is set in the side bending rod 10 and the clamping plate 16 is installed through it. The clamping plate clamps the horizontal I-beam 1.

[0015] As a preferred technical solution of this utility model, the right side of the sleeve frame 4 has an opening groove 41, and the right side is fixed with the side shaft 6 at the front and rear sides of the opening groove 41 respectively. The stud 7 is rotatably installed, and the side plate 8 is movably fitted with the side shaft 6 and installed in cooperation with the stud 7. The inner side of the side plate 8 is fixed with a locking block 9, which is made of rigid material.

[0016] As a preferred technical solution of this utility model, the clamping installation structure includes a wing plate 11, a connecting shaft 12, a rotating shaft 13, a knob 14, and an L-shaped mounting plate 15. The side bending rod 10 is integrally formed with the wing plate 11. The connecting shaft 12 is fixedly connected between the upper and lower wing plates 11 on the front side. The rotating shaft 13 is rotatably installed on the lower wing plate 11 on the rear side. The upper end of the rotating shaft 13 extends from the through hole on the upper wing plate 11 and the knob 14 is fixed at the extended end. The rotating shaft 13 has symmetrically threaded grooves on its side. The L-shaped mounting plate 15 is movably fitted with the connecting shaft 12 and is installed in conjunction with the threaded groove on the rotating shaft 13. A clamping plate 16 is fixedly connected between the front and rear L-shaped mounting plates 15.

[0017] As a preferred technical solution of this utility model, the surface of the card plate 16 is covered with a friction layer.

[0018] As a preferred technical solution of this utility model, the outer side of the knob 14 is provided with anti-slip grooves.

[0019] The working principle of this utility model is as follows: When using this steel structure frame for splicing, first, the vertical I-beams are positioned. Then, the sleeve is placed on the vertical I-beam, with its inner protrusion engaging the groove in the I-beam for initial positioning. Next, the splicing studs are passed through the screw holes on the side of the sleeve and the splicing holes at the ends of the horizontal I-beams, and tightened with nuts at the front ends. By adjusting the height of the sleeve on the vertical I-beam and tightening the nuts, the installation height of the horizontal I-beam can be determined. For the final fixing and tightening of the horizontal I-beam, the key lies in the operation of tightening the installation structure. The end of the horizontal I-beam is placed between the vertical parts of the front and rear L-shaped mounting plates, at which point the front and rear walls of the I-beam are in contact with the inner walls of the L-shaped mounting plates. Then, the knob is turned clockwise or counterclockwise to rotate the shaft. Because the rotating shaft has symmetrical threaded grooves (one section is left-handed and the other is right-handed), the two L-shaped mounting plates that mate with it will move inward or outward simultaneously under the drive of the threads. By rotating the knob, the two L-shaped mounting plates move towards each other, thereby causing the clamping plate between them to tightly clamp the lower flange (or upper flange) of the horizontal I-beam. The friction layer on the surface of the clamping plate further increases the friction force, ensuring the reliability of the clamping. Thus, the horizontal I-beam is subjected to shear force in the vertical direction by the splicing stud, and constrained by the clamping force provided by the clamping mounting structure in the horizontal and torsional directions, forming a stable and firm connection node. When disassembly is required, simply rotate the knob in the opposite direction to loosen the clamping of the horizontal I-beam, and then unscrew the nut at the front end of the splicing stud to easily remove the horizontal component and the sleeve, achieving quick and non-destructive disassembly.
