Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a telescopic steel structure frame. Background Art

[0002] In architecture, the frame is the core supporting structure of a building. It is composed of beams, columns and other components, just like the human skeleton. The main function of the frame is to bear the various loads of the building, including its own weight, personnel, equipment, and external forces such as wind and snow. The design of the frame determines key factors such as the spatial layout, height, and span of the building. Different frame materials, such as steel and concrete, can shape buildings of different styles, from simple to magnificent, providing a solid foundation and diverse forms for the building.

[0003] A steel frame is a building structure system constructed primarily of steel. It consists of steel beams, steel columns, and other components connected by welding and bolting. It boasts high strength and light weight, and can withstand heavy loads. It also boasts fast construction speeds, allows for large spans, and provides greater flexibility for architectural design. Furthermore, it boasts excellent seismic resistance and recyclability, making it widely used in modern architecture.

In projects requiring varying lengths, fixed-length frames cannot meet these changing requirements, leading to material waste or the need for re-customization due to inappropriate lengths, increasing costs and project time. Therefore, a retractable steel structural frame has been proposed to address these issues. Utility Model Content

One end of the one-way threaded rod 603 away from the horizontal plate 604 is fixedly connected to a turning handle 602, and the turning handle 602 is used to facilitate the rotation of the one-way threaded rod 603. The left and right sides of the horizontal plate 604 are rotatably connected to the turning rod 605. The ends of the two turning rods 605 away from the horizontal plate 604 are rotatably connected to the movable block 606. The turning rod 605 is used to connect the movable block 606 and the horizontal plate 604.

The outer periphery of the bidirectional threaded rod 705 is threadedly connected to two splints 706. The splints 706 are threadedly connected to the outer periphery of the bidirectional threaded rod 705, so that when the bidirectional threaded rod 705 rotates, the splints 706 can be driven to move. The end of the splint 706 away from the bidirectional threaded rod 705 is internally slidably connected to a limiting rod 707. The limiting rod 707 is fixedly connected to the inside of the fixed component 7. The limiting rod 707 is used to provide a limiting effect for the splint 706, so that the splint 706 always keeps moving horizontally.

[0037] Reference Figure 4 The limiting assembly 8 includes a limiting ring 801, which is movably connected to the outer periphery of the one-way threaded rod 603 near the horizontal plate 604. The outer periphery of the limiting ring 801 is movably connected to the inner bottom side of the shell 601. The limiting ring 801 is mainly used to provide a limiting effect for the one-way threaded rod 603 to prevent it from rotating. The inner sliding connection of the limiting ring 801 is connected to a movable ring 802, which is fixedly connected to the outer periphery of the one-way threaded rod 603. The movable ring 802 is fixed to the one-way threaded rod 603, and can drive the movable ring 80 when the one-way threaded rod 603 rotates. 2 rotates together, thereby controlling the rotation of the limit ring 801. The bottom of the limit ring 801 is slidably connected to a clamping block 803, which is used to fix the position of the limit ring 801. The bottom of the clamping block 803 is fixedly connected to the limit plate 804. The bottom of the limit plate 804 is respectively fixedly connected to a spring 805 and a pull rod 806. The spring 805 is sleeved on the outer periphery of the pull rod 806. The pull rod 806 is fixed to the limit plate 804. When the pull rod 806 moves, it can drive the limit plate 804 to move together, thereby squeezing the spring 805. The bottom of the pull rod 806 is fixedly connected to a pull block 807.

[0038] Working principle: When adjusting the length of the steel frame, first pull the pulling block 807 so that the pulling block 807 drives the pulling rod 806 to move downward. When the pulling rod 806 moves downward, it can drive the limiting plate 804 to move together, and then the limiting plate 804 will drive the card block 803 to slide out of the limiting ring 801 and squeeze the spring 805. After the card block 803 slides out of the limiting ring 801, the limiting ring 801 loses the limit of the card block 803, so that it can rotate. Then you can turn the handle 1 602. When the handle 1 602 rotates, since the shell 601 is fixed, the handle 1 602 will move while rotating, thereby controlling the horizontal plate 604 to move accordingly. When the horizontal plate 604 moves, the two rotating rods 605 will rotate in the opposite direction, thereby controlling the movement of the two movable blocks 606. When the two movable blocks 606 move, they will move in the limiting groove 608 through the limiting block 607, driving the clamping block 609 to move horizontally accordingly. After the two clamping blocks 609 lose contact with the convex steel frame 5, the I-shaped steel frame 4 can be moved. After the positions of the I-shaped steel frame 4 and the convex steel frame 5 are determined, the handle 1 602 can be reversed to make the one-way threaded rod 603 drive the cross plate 604 to move, so that the two rotating rods 605 rotate relative to each other, so that the two clamping blocks 609 contact the two convex steel frames 5 and apply a squeezing force to the convex steel frame 5, thereby fixing the positions of the convex steel frame 5 and the I-shaped steel frame 4. Because the transverse width of the convex steel frame 5 and the I-shaped steel frame 4 does not change after the adjustment of the position, after the two clamping blocks 609 contact the convex steel frame 5, the limiting ring 801 will also be reset accordingly, so that the clamping block 803 can slide into the limiting ring 801, forming a limit on the limiting ring 801, limiting the rotation of the one-way threaded rod 603, and then the I-shaped steel frame 4, the convex steel frame 5 and the connecting block 3 can be connected, and then the connecting block 3 can be installed on each fixing column 1;

[0039] When the height of the movable column 2 needs to be adjusted, first reverse the handle 702, and the handle 702 controls the rotation of the worm 703. At this time, the worm 703 controls the rotation of the worm wheel 704, and the worm wheel 704 drives the two-way threaded rod 705 to rotate, so that the two splints 706 move in opposite directions. The movable column 2 loses the limit of the splint 706 and can move. After the positions of multiple movable columns 2 are determined, turn the handle 702 forward, so that the two splints 706 move toward each other along the two-way threaded rod 705, thereby fixing the movable column 2.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
