[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides a movable steel pole device for bridge edge protection, such as... Figures 1-3 As shown, the structure includes prefabricated steel mesh 8. Adjacent prefabricated steel mesh 8 are connected and fixed by upright square steel bars 7. A base connecting rod square steel bar 5 is welded and fixed to one side of the bottom end of the upright square steel bar 7. A C-shaped clamp 2 is installed at the bottom of the base connecting rod square steel bar 5, and a movable screw 3 is installed at the top of the base connecting rod square steel bar 5. The C-shaped clamp 2 clamps and fixes the beam flange, and the bottom end of the movable screw 3 presses and positions it. The upright square steel bars 7 connect and fix adjacent prefabricated steel mesh 8, forming a stable protective net structure. The base connecting rod square steel bar 5 welded and fixed to one side of the bottom end of the upright square steel bar 7 enhances the stability and support of the upright. The C-shaped clamp 2 installed at the bottom of the base connecting rod square steel bar 5 allows the device to be easily clamped onto the beam flange, realizing a quick connection with the beam. At the same time, the movable screw 3 is installed at the top of the base connecting rod square steel bar 5. By rotating the movable screw 3, its bottom end can be pressed against the beam flange, further fixing the position of the device. This structural design not only facilitates the installation and disassembly of the device but also effectively protects the beam structure, avoiding damage to the beam caused by traditional fixing methods and improving construction safety and efficiency. Specifically, the snap-fit ​​fixing of the C-shaped clamp 2 to the beam flange and the clamping positioning of the movable screw 3 together ensure the stability and reliability of the device.

[0026] In this embodiment, several horizontal square steel bars 6 are installed on the upright square steel bars 7, and the horizontal square steel bars 6 are connected and fixed to the side of the finished steel mesh 8. By connecting and fixing the side of the finished steel mesh 8 with the horizontal square steel bars 6, the overall stability and rigidity of the protective net structure are enhanced, making the edge protection of the bridge more reliable.

[0027] Specifically, an annular nut 4 is welded and fixed to the square steel of the base connecting rod 5, and the movable screw 3 is threadedly connected to the annular nut 4. The annular nut 4 welded to the square steel of the base connecting rod 5 and the movable screw 3 are threadedly connected, realizing the adjustability of the movable screw 3, which is convenient for adjustment according to the thickness and shape of the beam flange, improving the adaptability and installation convenience of the device.

[0028] Furthermore, there are two crossbars 6, and the sides of the finished steel mesh 8 are fixed to the crossbars 6 with wire. Using two crossbars 6 to fix the sides of the finished steel mesh 8 with wire increases the connection points of the protective mesh structure, improving its wind pressure resistance and overall stability.

[0029] Furthermore, a gasket 1 is welded and fixed to the inner bottom wall of the C-shaped clamp 2, and the top of the C-shaped clamp 2 is welded and fixed to the square steel of the base connecting rod 5. The gasket 1 welded to the inner bottom wall of the C-shaped clamp 2 increases the contact area with the beam flange, disperses the pressure, and protects the beam structure. At the same time, the welding and fixing of the top of the C-shaped clamp 2 to the square steel of the base connecting rod 5 enhances the connection strength and ensures the stability of the device.

[0030] Furthermore, the top of the movable screw 3 is provided with a transverse shaft hole through which a movable screw rod 31 passes. A pressure plate 32 is installed at the bottom of the movable screw 3. The transverse shaft hole at the top of the movable screw 3 through which the movable screw rod 31 passes facilitates manual rotation of the movable screw 3 for adjustment. The pressure plate 32 installed at the bottom increases the contact area with the beam flange, improves the clamping effect, and ensures the stability of the device.

[0031] Furthermore, gasket 1 has a square structure with dimensions of 30×30×2mm. The square structure of gasket 1, with dimensions of 30×30×2mm, ensures sufficient contact area while avoiding unnecessary pressure or gaps on the beam structure caused by excessively large or small dimensions, thus improving the adaptability and protective properties of the device.

[0032] Furthermore, the wire passes through the hollow part of the crossbar square steel 6 from one end of the finished steel mesh 8 to the other end of the finished steel mesh 8, and is then wrapped and fixed in the middle of the upright square steel 7. This process enhances the overall continuity and stability of the protective netting structure, preventing the finished steel mesh 8 from loosening or falling off.

[0033] In use, the movable steel pole device for bridge edge protection of this utility model first connects and fixes the prefabricated steel mesh 8 through the upright square steel 7 to form a basic protective mesh structure. The upright square steel 7 serves as a vertical support, tightly connecting adjacent prefabricated steel mesh 8 together. A base connecting rod square steel 5 is welded and fixed to one side of the bottom end of the upright square steel 7, enhancing the stability and support force of the pole. At the bottom of the base connecting rod square steel 5, a U-shaped clamp 2 is installed, and a gasket 1 is welded to its inner wall. The gasket 1 increases the contact area with the beam flange, dispersing pressure and protecting the beam structure.

[0034] A ring nut 4 is welded to the top of the square steel rod 5 of the base connecting rod, and a movable screw rod 3 is connected by threads. The top of the movable screw rod 3 is provided with a transverse shaft hole, through which a movable screw rod 31 is inserted for easy manual rotation and adjustment. A pressure plate 32 is installed at the bottom end, which increases the contact area with the beam flange and improves the clamping effect.

[0035] The assembled device was brought to the bridge construction site, and the C-shaped clamp 2 was fastened to the beam flange, achieving a quick connection with the beam. By rotating the movable screw rod 31, the position of the movable screw rod 3 was adjusted so that its bottom end pressed against the beam flange, further fixing the position of the device. The pressure plate 32 ensured the clamping effect, making the device stable and reliable.

[0036] Two horizontal square steel bars 6 are installed on the upright square steel bar 7, and the sides of the finished steel mesh 8 are fixed to the horizontal square steel bars 6 with wire. This increases the connection points of the protective net structure, improving its wind pressure resistance and overall stability. Wire passes through the hollow part of the horizontal square steel bar 6 from one end of the finished steel mesh 8 to the other end, and is then wrapped and fixed in the middle of the upright square steel bar 7. This enhances the overall continuity and stability of the protective net structure, preventing the finished steel mesh 8 from loosening or falling off.

[0037] During construction, this device effectively prevents workers from falling from the bridge edge, providing reliable safety protection. When it is necessary to move or disassemble the device, simply loosen the movable screw 3 to easily remove it from the beam, facilitating subsequent construction and maintenance.
