Two side connecting blocks 704 are symmetrically arranged on the outer sides of the first supporting base plate 1 and the second supporting base plate 2, and a baffle fixing screw 705 is inserted in the inner thread of the side connecting block 704. The end of the baffle fixing screw 705 extends into the edge protection fence 701 and conflicts with the side of the closed baffle 703.

[0030] The outer anti-fall component 8 includes a side anti-fall frame 801 arranged on the outer side of the first supporting base plate 1 and the second supporting base plate 2, and an anti-fall net 802 is arranged on the side anti-fall frame 801. Two side fixing blocks 803 are arranged on the sides of the first supporting base plate 1 and the second supporting base plate 2. A rotating connecting rod 804 is rotatably arranged in the middle of the two side fixing blocks 803. The rotating connecting rod 804 passes through the bottom of the side anti-fall frame 801. A connecting column 805 is arranged on the top side of the side anti-fall frame 801.

[0037] In this embodiment, since the existing bridge construction work platform has large gaps in the side guardrails, it is easy to cause the construction tools to fall, and there are certain safety hazards to personal safety, which does not meet the construction standards for safe operations.

[0038] In summary, in a specific implementation, a connecting block 3 is provided on the side of the second supporting base plate 2, and the end of the connecting block 3 is inserted into the side of the first supporting base plate 1. The second supporting base plate 2 is fixedly connected to the first supporting base plate 1 by a fastening bolt 4 inserted through the connecting block 3, so that the first supporting base plate 1 and the second supporting base plate 2 can be more conveniently installed on both sides of the pier, and the disassembly and assembly between the first supporting base plate 1 and the second supporting base plate 2 is also more convenient.

[0039] The edge anti-fall component 7 arranged on the top of the first supporting base plate 1 and the second supporting base plate 2, wherein the edge protection fence 701 in the edge anti-fall component 7 can provide protection for the side edges of the top ends of the first supporting base plate 1 and the second supporting base plate 2, and the anti-fall baffle 702 and the closed baffle 703 arranged on the edge protection fence 701 can block the larger gap left at the bottom of the edge protection fence 701, so that the junction between the edge protection fence 701 and the first supporting base plate 1 and the second supporting base plate 2 can be in a sealed state, thereby preventing the construction tools placed on the first supporting base plate 1 and the second supporting base plate 2 from falling.

[0040] An outer anti-fall component 8 is arranged on the side of the first supporting base plate 1 and the second supporting base plate 2, wherein the bottom end of the side anti-fall frame 801 in the outer anti-fall component 8 passes through the limit by rotating the connecting rod 804, so that the deflection angle of the side anti-fall frame 801 and the anti-fall net 802 arranged thereon can be adjusted, so that the anti-fall net 802 can protect the sides of the first supporting base plate 1 and the second supporting base plate 2 again, so as to achieve the effect of preventing the hand tools of the workers from slipping when working on the first supporting base plate 1 and the second supporting base plate 2 and being intercepted again.

[0041] It can also intercept the falling stones on the bridge piers during the workers' operation, which can not only provide better anti-fall protection for the workers' tools and personal safety, but also effectively block the falling stones and other debris during the operation, which has a more effective anti-fall effect and is more convenient for users to use.
