[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Example 1: This Example 1 provides an adaptive base for an I-beam cantilever scaffold. It is a direct improvement on an existing I-beam cantilever scaffold base, featuring a unique structure. Please refer to [link / reference]. Figure 1-4 As shown, the device includes an I-beam 1 and an adjustment mechanism mounted on the upper flange of the I-beam 1. The adjustment mechanism includes two fixed plates 2 fixedly mounted on the I-beam 1 and a connecting pipe 7 positioned between the two fixed plates 2. The two fixed plates 2 are symmetrically positioned on both sides of the web of the I-beam 1. A sleeve 8 is movably fitted in the middle of the connecting pipe 7. The lower part of the fixed plate 2 has a through hole 4, the middle part has a limit groove 5 horizontally positioned, and the upper part has an arc-shaped groove 6 concentric with the through hole 4. A screw rod II 10 is movably fitted inside the through hole 4. A nut II 13 is threaded onto one exposed end of the screw rod II 10, and the other end is fixedly connected to the connecting pipe 7.

[0017] A screw rod Ⅲ11 is movably fitted inside the limiting groove 5. A nut Ⅲ14 is threaded onto the exposed end of the screw rod Ⅲ11, and the other end is fixedly connected to the sleeve 8. A screw rod Ⅰ9 is movably fitted inside the arc-shaped groove 6. A nut Ⅰ12 is threaded onto the exposed end of the screw rod Ⅰ9, and the other end is fixedly connected to the connecting pipe 7. A screw cylinder Ⅱ17 communicating with its interior is fixedly installed on the upper part of the connecting pipe 7. A bolt Ⅱ18 is threaded onto the interior of the screw cylinder Ⅱ17. A screw cylinder Ⅰ15 communicating with its interior is fixedly installed on the sleeve 8. A bolt Ⅰ16 is threaded onto the interior of the screw cylinder Ⅰ15. There are two screw cylinders Ⅰ15 and two screw cylinders Ⅱ17, and the two screw cylinders Ⅰ15 and the two screw rods Ⅰ9 are arranged in a cross shape.

[0018] Working principle: When setting up cantilevered scaffolding, first fix the I-beam 1 to the floor slab or wall, then insert the scaffolding upright into the connecting pipe 7, and tighten the two bolts II18 to fix the upright and the connecting pipe 7 together. Then rotate the upright along the axis of the screw II10 to adjust the position of the upright until it is vertical. At this time, tighten the nuts I12, II13 and III14 in sequence to fix the connecting pipe 7. Then tighten the bolt I16 to fix the connecting pipe 7 to the sleeve 8, thereby further preventing the connecting pipe 7 from moving during construction. Through the design of the adjustment mechanism, the position of the scaffolding upright can be adjusted to keep the scaffolding upright in a vertical state and improve the stability of the scaffolding.

[0019] Example 2: The difference between Example 2 and Example 1 is as follows: Figure 1-4As shown, it also includes a fixing assembly. Both fixing plates 2 are fixedly connected to the I-beam 1 through the fixing assembly. The fixing assembly includes bolts III 19 and U-shaped plates 20 that are clamped onto the upper flange of the I-beam 1. The lower end of the fixing plate 2 is fixedly connected to the U-shaped plate 20. Through holes for bolts III 19 to be inserted are provided on the upper and lower side walls of the U-shaped plate 20 and the upper flange of the I-beam 1. The U-shaped plate 20 and the fixing plate 2 are bent as one piece. Ribs 3 are fixedly installed on both ends of the fixing plate 2 away from the connecting pipe 7. The lower end of the ribs 3 is fixedly connected to the U-shaped plate 20. By using the fixing assembly, the fixing plate 2 can be detachably installed on the I-beam 1, which not only allows the adjustment mechanism to adapt to I-beams of different sizes, but also allows the distance between the scaffold uprights and the wall to be adjusted.
