Description

Technical Field

[0001] The utility model relates to the technical field of scaffolds, in particular to a scaffold for building construction with an anti-overturning structure. Background Art

[0002] Scaffolding is a working platform set up to ensure the smooth progress of each construction process. On construction sites, scaffolding is often used by workers, especially for painting in rooms. Most of them use simple scaffolding that is easy to build and dismantle. Traditional scaffolding is formed by combining two fixed clamps and multiple connecting plates. When it is placed on an uneven ground, the heights of the multiple support columns will be unequal, causing some support columns to be suspended from the ground, making the scaffolding unstable. Generally, bricks or pads are placed at the bottom of the support columns to keep the scaffolding level. Only when the thickness of the bricks or pads matches the ground clearance of the support columns can the scaffolding be in a stable state. When the height of the bricks or pads does not match the ground clearance of the support columns, the heights of multiple support columns are different. This method may cause tilting and shaking during operation, and in severe cases, it may cause the scaffolding to overturn. The risk factor is high, and there are great safety hazards during operation.

[0003] Chinese Patent: CN217734758U, which discloses a highly stable anti-overturning scaffolding, the scaffolding drives the screw rod to rotate by rotating the handle. Since the bottom end of the screw rod is rotatably connected to the lower fixed seat, and the screw rod is threadedly connected to the movable block, the screw rod can drive the movable block to move downward during the rotation process, and the movable block can make the support rod and the connecting rod rotate around one end thereof during the downward movement. When the bottom end of the connecting rod contacts the ground, the handle is continued to be rotated until the four corners of the scaffold are adjusted to a horizontal state, making it more stable during operation and avoiding causing the scaffold to overturn. The above-mentioned device can increase the stability of the scaffolding by setting four pads, but in actual use, the scaffolding needs to be increased according to the construction height. When the scaffolding height increases, since the above-mentioned scaffolding connecting rod is of fixed length, it is not convenient to increase the distance between the pad and the scaffolding during use, thereby making it inconvenient to keep the scaffold stable.

[0004] Based on this, a scaffold for building construction with an anti-overturning structure is now provided, which can eliminate the disadvantages of the existing devices. Utility Model Content

During use, when it is necessary to adjust the working position of the cushion block 20, the torsion block 25 is rotated, and the torsion block 25 drives the second threaded rod 24 to rotate. Under the action of the thread, the connecting plate 23 drives the sliding ring 16 to slide on the sliding sleeve 15 through the rotating ring 17. When the sliding ring 16 moves, the sliding ring 16 pushes the output end of the telescopic rod 19 to move through the first connecting rod 18, and the output end of the telescopic rod 19 drives the cushion block 20 to move, thereby adjusting the working position of the cushion block 20.

[0027] The outer side of the twist block 25 is provided with anti-skid knurling, which makes it easy to rotate the twist block 25 to adjust the working position of the cushion block 20 when in use.

When in use, when the main frame needs to be protected, the sliding sleeve 15 is rotated to expand the pad 20, and then the sliding sleeve 15 is pressed so that one end of the limit block 28 is inserted into a first limit groove, thereby fixing the position of the telescopic rod 19, and then the first threaded rod 22 is rotated to adjust the working height of a single pad 20. When the sliding sleeve 15 needs to be released, the sliding plate 31 is pressed down, and the sliding plate 31 moves along the second guide The sliding rod slides in the axial direction, so that the two ends of the sliding plate 31 drive the two second connecting rods 30 to move, and the second connecting rod 30 pushes the sliding frame 27 to slide, and the sliding frame 27 drives the limit block 28 to move so that the limit block 28 is disengaged from the first limit groove, thereby releasing the fixation of the sliding sleeve 15. Then, under the action of the first tension spring 26, the sliding sleeve 15 slides on the support tube 11 and returns to the initial position, so that the bottom end of the pad 20 is separated from the ground. The upper end of the fixed connecting plate 14 is provided with a locking assembly for fixing the sliding plate 31.

[0029] The locking assembly includes two symmetrically arranged mounting plates 33, the mounting plates 33 being slidably arranged in the limiting slide grooves at the upper end of the fixed connecting plate 14, the inner sides of the limiting slide grooves are provided with guide slide grooves, and limiting sliders are provided at the positions corresponding to the guide slide grooves on both sides of the mounting plate 33.

The two sliding sleeves 15 are rotated to expand the pad 20 and loosen the sliding plate 31. Since there is only one second limiting groove, one end of the limiting block 28 is in close contact with the inside of the sliding sleeve 15. The torsion block 25 is rotated, and the torsion block 25 drives the second threaded rod 24 to rotate. Under the action of the thread, the connecting plate 23 drives the sliding ring 16 to slide on the sliding sleeve 15 through the rotating ring 17.
