Description

Technical Field

[0001] This utility model relates to the field of scaffolding technology, and more specifically, to a detachable steel column structure for scaffolding. Background Technology

[0002] With the acceleration of urbanization in my country, the number of high-rise buildings in cities is increasing year by year. Attached lifting scaffolding only requires a frame four to five times the height of the building, and can be raised and lowered according to the construction progress using a lifting device, meeting the needs of building structure construction and exterior wall decoration construction. It transforms high-altitude work into low-altitude work, and suspended work into work inside the scaffold, with significant low-carbon characteristics, high-tech content, and is more economical, safer, and more convenient.

[0003] During the use of existing scaffolding on the market, it has been found that most scaffolding has relatively simple and fixed design and installation of guardrails. Gaps may exist between the guardrails, which may lead to objects falling and cause safety hazards. Therefore, it is clear that the design and installation of scaffolding guardrails are particularly important. Existing guardrails are difficult to adapt to users of different heights and different usage situations.

[0004] A search revealed that Chinese patent CN220768781U discloses an attached lifting scaffold. This scaffold can be adjusted using protective plates and adjusting plates within a protective structure, achieving the effect of fixing the protective plates and adjusting plates. When the scaffold moves along the mounting frame, the moving block moves along a rectangular slide groove on the surface of a rectangular slider on the mounting frame, achieving an adjustment effect. This facilitates the lifting and adjustment of the scaffold, thus achieving a protective effect.

[0005] In actual use, the above-mentioned attached lifting scaffolding is usually made of integral welded steel. As the building structure has different floor heights, it is not convenient to use on higher floors. In addition, the use of a lot of bolts makes disassembly and installation difficult during use, installation, dismantling and turnover. Utility Model Content

A first bevel gear is rotatably connected inside the connecting plate. A first hexagonal nut is fixedly connected to the bottom of the first bevel gear. A second bevel gear meshes with one side of the first bevel gear. A bidirectional screw is fixedly connected inside the second bevel gear. A threaded sleeve is threadedly connected to the outer side of the bidirectional screw. The threaded sleeve is slidably connected to the inside of the connecting plate. A limit rod is fixedly connected to one side of the threaded sleeve. The limit rod is adapted to the inner side of the positioning block and is inserted through the positioning block into the inner side of the connecting plate. A threaded rod is threadedly connected inside the connecting plate. A second hexagonal nut is fixedly connected to one end of the threaded rod. Two connecting blocks are fixedly connected to the top of the connecting plate. A limit plate is rotatably connected to one end of the threaded rod and is inserted into the inner side of the connecting block.

[0008] By adopting the above technical solution, two standard columns can be quickly connected, and the two standard columns can be tightly connected by double-layer limiting, thereby reducing on-site welding or complex assembly steps.

[0009] As a further description of the above technical solution: the split mechanism includes multiple diagonal braces, which are welded and fixed to the inner side of the standard column and the top column respectively. A lifting bracket is fixedly connected to one side of the top column by bolts. Multiple mounting holes are opened inside the column base, and the mounting holes are fixedly connected to the bottom end of one of the standard columns by bolts.

[0020] The embodiments disclosed in this application are as follows: Figure 1-6 The scaffolding detachable steel column structure shown includes a column base 1, a plurality of standard columns 2 are set at the top of the column base 1, a top column 3 is set on the standard columns 2, both the standard columns 2 and the top column 3 are integral frame structures and are bolted together, both the standard columns 2 and the top column 3 are fixedly connected to the bottom of the standard columns 2 and the top column 3, the standard columns 2 are equipped with connecting components, and the column base 1 is equipped with a split mechanism; The connecting assembly includes multiple positioning blocks 5, which are fixedly connected to the top of the standard column 2.

A second bevel gear 8 meshes with one side of the first bevel gear 6. A bidirectional screw 9 is fixedly connected inside the second bevel gear 8. A threaded sleeve 10 is threadedly connected to the outside of the bidirectional screw 9. The threaded sleeve 10 is slidably connected to the inside of the connecting plate 4. A limit rod 11 is fixedly connected to one side of the threaded sleeve 10. The limit rod 11 is adapted to the inner side of the positioning block 5 and penetrates through the positioning block 5 to insert into the inner side of the connecting plate 4. A threaded rod 12 is threadedly connected inside the connecting plate 4. A second hexagonal nut 13 is fixedly connected to one end of the threaded rod 12. Two connecting blocks 15 are fixedly connected to the top of the connecting plate 4. One end of the threaded rod 12 rotates. A limiting insert plate 14 is connected and inserted into the inner side of the connecting block 15. By rotating the first hexagonal nut 7, the first bevel gear 6 can mesh and drive the second bevel gear 8 to rotate, so that the second bevel gear 8 can drive the bidirectional screw 9 to move. The bidirectional screw 9 can drive the threaded sleeve 10 to drive the limiting insert rod 11 to move, so that the limiting insert rod 11 can pass through the positioning block 5, thereby limiting multiple positioning blocks 5, so that the two standard columns 2 can be connected. By rotating the threaded rod 12, the limiting insert plate 14 can be pushed to insert into the connecting block 15. The multiple protrusions on one side of the limiting insert plate 14 can increase the contact area with the connecting block 15, so as to improve the stability of the connection between the two standard columns 2 and enable the two standard columns 2 to be quickly positioned, installed and connected.

The assembly height of the device can be changed to meet the project construction requirements.

[0022] Working principle of this utility model: This utility model designs a detachable steel column structure for scaffolding. The specific structure is shown in the attached instruction manual. Figure 1-6As shown, in this technical solution, through the cooperation between various structures, when the scaffolding needs to be assembled, firstly, the column base 1 is placed in a suitable position, and the bottom end of one standard column 2 is fixed to the mounting hole 18 with bolts. Then, the connecting plate 4 at the bottom end of another standard column 2 is placed on the fixed standard column 2. During installation, multiple positioning blocks 5 and two connecting blocks 15 are aligned with the inner side of the connecting plate 4, so that the multiple positioning blocks 5 and two connecting blocks 15 can be inserted into the inner side of the connecting plate 4. Then, the first hexagonal nut 7 is rotated in sequence, which drives the first bevel gear 6 to mesh with the second bevel gear 8 to rotate, so that the second bevel gear 8 can drive the double-direction screw 9 to rotate, so that the double-direction screw 9 can be... The threaded sleeve 10 moves by driving the threaded drive, which in turn pushes the limiting rod 11 to move. This allows the limiting rod 11 to pass through the positioning block 5 and be inserted into the inner side of the connecting plate 4. The "+" shaped design of the limiting rod 11 increases the contact area with the positioning block 5, thus better limiting the positioning block 5 when it passes through it. Then, the second hexagonal nut 13 is rotated, which drives the threaded rod 12 to rotate. This allows the threaded rod 12 to drive the limiting plate 14 to move towards the connecting block 15. The limiting plate 14 can be inserted into the connecting block 15, increasing the contact area with the connecting block 15 and facilitating the connection between the two standard columns 2, making the connection between the two standard columns 2 more stable.
