[0018] In order to better understand the purpose, structure and function of the present utility model, the following further describes in detail a capping beam high-altitude safety protection device of the present utility model with reference to the accompanying drawings.

[0019] As Figures 1 to 4 shown, a capping beam high-altitude safety protection device includes a gantry 1 providing overall strength and stiffness and a guide cable 2 for hanging a safety belt 5 and a safety rope 6. The gantry 1 is trapezoidal and there are three in total, respectively at both ends and in the middle of the capping beam 8. The gantry 1 includes columns 3 on both sides, an upper connecting beam and a lower connecting beam.

[0020] This device connects the three gantries 1 into a whole through the guide cable 2. Workers hang the hooks of the safety belt 5 and the fall arrester 7 on the guide cable 2, and the safety rope 6 connected to the fall arrester 7 is connected to the safety belt 5 for high-altitude operations.

[0021] In this embodiment, the gantry 1 is made of [10 channel steel, which can ensure the strength and stiffness of the gantry 1 and the safety of construction workers. The width and height dimensions of the gantry 1 can be dynamically adjusted according to the capping beam 8. The columns 3, the upper connecting beam and the lower connecting beam are all composed of two [10 channel steels partially overlapping, and the overlapping sections are bolted and fixed. Construction workers can adjust the length of the overlapping sections according to their own needs, which is convenient for adapting to the mobile operations of construction workers on capping beams 8 of different sizes, and ensuring a safe and comfortable construction environment for construction workers.

[0022] The gantry 1 is fixed to the side formwork of the capping beam by using the anchor points 4 of the protection device. The anchor points 4 of the protection device are composed of high-strength bolts and backing plates. The backing plates are fixed on the lower connecting beam, and the backing plates are connected to the side formwork of the capping beam through high-strength bolts to ensure the overall stability of the gantry 1.

[0023] The guide cable 2 is composed of 8mm steel wire ropes. It adopts steel cables with high strength, good wear resistance and can maintain stability in the high-altitude environment, and can bear the weight of construction workers and the impact force of falling.

[0024] During the construction of the pier capping beam, a gantry 1 made of [10 channel steel with adjustable height and width is used. The gantry 1 is composed of columns 3 and connecting beams. Part of the columns 3 is in an octagonal shape, with a vertical height of 2m, the width of the upper connecting beam is 1m, and the width of the lower connecting beam is 2.4m. The width of the gantry 1 can be adjusted according to the different widths of the capping beam 8. The columns 3 and the connecting beams are connected into a whole through Φ20 bolts and nuts. 10cm×10cm backing plates are fully welded under both ends of the lower connecting beam. In the form of drilling holes in the side formwork of the capping beam, Φ20 bolts pass through the backing plates and are anchored to the template holes together. A reserved hole is provided in the middle of the upper connecting beam and washers are installed. The guide cable 2 uses 8mm steel cables to pass through the washers to connect three gantries 1 into a whole. Workers hang the hooks and anti-falling devices 7 of the safety belts 5 on the guide cable 2. After the safety ropes 6 connected to the anti-falling devices 7 are connected to the safety belts 5, high-altitude operations are carried out.
