The lapping hook is movably connected with a connecting shaft, and a worm gear and a locking plate are fixed on the outer surface of the connecting shaft. A worm is arranged inside the fixed box. Limit plates and limit grooves are respectively arranged on the outer surface and the back of the framework. Strengthening rods are welded inside the framework.

[0007] Furthermore, water leakage holes and anti-slip convex blocks are respectively arranged on the top of the pedal.

[0008] By adopting the above technical scheme, the water leakage holes serve the purpose of discharging accumulated water, and the anti-slip convex blocks increase the friction of the soles of the feet, thereby preventing the situation of slipping under the feet.

[0009] Furthermore, there are two groups of limit plates and limit grooves respectively, and the limit plates are adapted to the limit grooves.

[0010] By adopting the above technical scheme, under the lapping action of the limit plates and the limit grooves, adjacent steel gangplanks are not prone to move.

[0011] Further, a plurality of reinforcing bars are provided, and the plurality of reinforcing bars are equidistantly distributed at the bottom of the pedal.

[0012] By adopting the above technical solution, under the action of the reinforcing bars, the bearing capacity and stability of the steel formwork are improved, and thus the steel formwork is not easily deformed.

[0013] Further, a first reinforcing plate is also provided on the inner sides of the framework and the reinforcing bars.

[0014] By adopting the above technical solution, the first reinforcing plate can improve the firmness between the connection of the framework and the reinforcing bars, and it is not easy to appear the situation of weld detachment.

[0015] Further, the worm is engaged with the worm gear, and a knob is fixed at the end of the worm.

[0016] By adopting the above technical solution, the staff can rotate the worm through the knob, thereby making the worm gear rotate. Moreover, the cooperation of the worm gear and the worm has self-locking property, making the locking plate more stable after clamping.

[0017] Further, a second reinforcing plate is fixed between the overlapping hook and the framework.

[0018] By adopting the above technical solution, the second reinforcing plate can improve the firmness and stability between the overlapping hook and the framework.

[0019] Further, both the second reinforcing plate and the first reinforcing plate are triangular.

[0020] By adopting the above technical solution, the triangular design makes the first reinforcing plate and the second reinforcing plate more stable.

[0021] Further, both the locking plate and the overlapping hook are arc-shaped.

[0022] By adopting the above technical solution, the arc-shaped design can better fit the surface of the scaffolding steel pipe, and it is more stable after overlapping.

[0023] In summary, the present utility model mainly has the following beneficial effects:

[0024] 1. The present utility model is provided with a locking plate, a connecting shaft, a worm gear and a worm. After the overlapping hook is clamped on the scaffolding steel pipe, the staff rotates the worm, and the rotation of the worm makes the worm gear rotate, thereby making the connecting shaft drive the locking plate to turn over from bottom to top, so that the locking plate clamps the bottom of the scaffolding steel pipe, achieving the purpose of locking. It can effectively prevent the hook from detaching. Moreover, whether it is installation or disassembly, only two operations are required, greatly reducing the operation steps and improving the work efficiency;

[0025] 2. Through the cooperation of the limit plate and the limit groove, the utility model can facilitate the buckling of two adjacent steel gangplanks, making the contact between adjacent gangplanks firm, not prone to deviation, and improving stability. BRIEF DESCRIPTION OF THE DRAWINGS
