When the support plate 11 moves and drives the grid frame 13 to move, the support area of ​​the bridge construction safety platform can be increased, thereby achieving the purpose of increasing the support area, which is convenient for adjusting the support area of ​​the bridge construction safety platform according to the construction conditions. When the support plate 11 moves and drives the grid frame 13 to move, it will drive the guide rod 7 to slide inside the guide cylinder 6, thereby moving the position of the guide rod 7. The guide rod 7 cooperates with the guide cylinder 6 to block the space on the side of the bridge construction safety platform. After the bridge construction is repaired, when the impurities dropped on the bridge construction safety platform are cleared, the micro-blower 18 is operated to extract the air inside the bellows 16 to generate wind force, and the wind force will flow into the interior of the circulation slot 20, and then through the jet hole 21, the wind force will flow to the surface of the workbench 1, thereby removing the dropped impurities, thereby improving the cleaning efficiency, and no manual cleaning with the help of tools is required, thereby reducing the labor intensity.
