Abstract
Description
Technical Field
[0001] This utility model relates to the field of scaffolding fastener technology, specifically a movable cantilever scaffolding fixing fastener. Background Technology
[0002] Couplers for cantilever scaffolding are responsible for connecting the scaffolding to the building structure, ensuring the stability and safety of the scaffolding. They are usually called cantilever scaffolding embedded parts or cantilever beam couplers. Their main function is to connect the scaffolding to the building structure. Through couplers, the scaffolding can be firmly fixed to the building structure, preventing swaying or tilting during construction, thereby ensuring the safety of construction workers.
[0003] According to the application number CN202221211109.6, a fixing buckle for cantilever scaffolding uprights is proposed. This solution solves the problems of existing fixing methods, such as the difficulty of installation and dismantling by workers, poor safety, and easy loosening during use.
[0004] However, the following problems still exist in actual use:
[0005] (1) When in use, the elastic spring is prone to failure due to fatigue or corrosion during long-term use, resulting in a decrease in locking force and potential safety hazards. Furthermore, the elasticity of the spring is greatly affected by the ambient temperature, which may lead to unstable locking function under high or low temperature conditions, making it unsuitable for widespread use in reality.
[0006] (2) When in use, the design of the locking buckle and hook is usually designed for steel pipes of a specific diameter, which is difficult to adapt to steel pipes of different diameters or shapes. The versatility is poor. When the diameter of the steel pipe changes, the contact area between the locking buckle and the steel pipe decreases, resulting in insufficient friction and easy slippage or loosening, which reduces the practicality in actual use.
[0007] Therefore, this utility model introduces a movable cantilever scaffold fixing fastener. Utility Model Content

[0026] Please see Figure 4 An adjustment mechanism 19 is provided on the right side of the rectangular block 9. The adjustment mechanism 19 includes an adjustment block 14, a locking plate 15, a connecting screw 16, and an abutment bolt 17. An adjustment groove 13 is opened inside the rectangular block 9.

[0027] Please see Figure 1 and Figure 2The upper surface of the I-beam 1 abuts against the steel pipe 2, and the outer surface of the steel pipe 2 abuts against the right side of the locking plate 15.

[0028] Working principle: When using, first connect the whole assembly to the I-beam 1. First, abut the top of the T-block 3 against the bottom of the I-beam 1. Then, install the fastening screws 8 inside the T-block 3 to initially fix the position between the T-block 3 and the I-beam 1. Next, abut the left side of the T-block 3 against the L-block 4. Through the rectangular groove 5 inside the L-block 4, slide the T-plate 6 inside the rectangular groove 5. Abut the top of the T-plate 6 against the bottom of the T-block 3. After the T-plate 6 and T-block 3 are abutted, install the fastening bolts 7 inside the T-block 3 and T-plate 6 to fix their positions again. Then, install the rectangular block 9 between the right side of the L-block 4 and the top of the I-beam 1. The top of the rectangular block 9 and the right side of the L-block 4 are installed and limited by the first limiting screw 11 and the second limiting screw 12. Thus, the I-beam 1 can be used for limiting and supporting operations.
[0029] When limiting the movement of steel pipes 2 of different diameters on the I-beam 1, the adjusting block 14 can slide on the inner wall of the adjusting groove 13 opened inside the rectangular block 9. The locking plate 15 fixedly installed on the right side of the adjusting block 14 can abut against the outer surface of the steel pipe 2. The anti-slip groove on the right side of the locking plate 15 increases the friction between it and the steel pipe 2, ensuring stability during the limiting process. Finally, the connecting screw 16 is installed inside the rectangular block 9 and the adjusting block 14, and the connecting screw 16 is threaded with the abutment bolt 17. The back of the abutment bolt 17 abuts against the front of the rectangular block 9, further ensuring the stability of the steel pipe 2 when placed on top of the I-beam 1.
