[0029] Example 1:

[0030] like Figure 1 、 2As shown in FIGS. 1, 2 and 3, the bridge falling prevention device provided by the embodiment comprises a plurality of overhangs 1, transverse protection lines 2 and longitudinal protection lines 3. The overhangs 1 are arranged on both sides of the bridge, and the overhangs 1 on each side are arranged along the direction of the bridge. Each overhang 1 is fixedly connected with the wing plate 8 of the bridge. The overhang 1 can be made of stainless steel and welded from a stainless steel plate. A plurality of reserved holes 4 are arranged on each overhang 1. Each longitudinal protection line 3 passes through the reserved hole 4 and is fixed with the overhang 1 at the head of the bridge. The transverse protection lines 2 are staggered and woven with the longitudinal protection lines 3 to form a falling prevention net.

[0031] The reserved holes 4 on the overhangs 1 can provide sufficient bearing capacity for the longitudinal protection lines 3. The falling prevention net which is staggered and woven can prevent the transverse and longitudinal protection lines from slipping and prevent people from falling from the gap, thereby achieving good protection effect.

[0032] Specifically, each overhang 1 has a straight section 101 and an arc section 102. The straight section 101 is fixedly connected with the wing plate 8 on both sides of the bridge and is perpendicular to the wing plate 8 of the bridge. The arc section 102 extends upward and outward. The reserved holes 4 are arranged on the arc section 102. The overhang 1 of the embodiment can be connected by welding or bolt fixing. The bolt fixing is preferred. The stainless steel overhang 1 can be processed in the factory, thereby avoiding the uncontrollable quality of on-site welding, greatly improving the welding quality of the overhang 1 and making the structure more safe and reliable. At the same time, the overhang 1 can be fixed on the flange plate of the bridge by bolts during on-site construction, thereby improving the construction progress and reducing the interference of construction on the normal operation of the bridge.

[0033] Embodiment 2

[0034] On the basis of the embodiment 1, in order to improve the structural strength of the falling prevention net, the hole diameter of the reserved holes 4 at both ends of each overhang 1 is larger than that of the other reserved holes 4. The transverse locking support pipe 5 passes through the reserved hole 4 with larger hole diameter at the end. The two ends of the transverse protection line 2 are fixedly connected with the corresponding transverse locking support pipe 5. The transverse locking support pipe 5 provides strong support for the transverse protection line 2 and strengthens the strength of the whole falling prevention net. Of course, the transverse locking support pipe 5 can also be fixed by other ways in the utility model, such as being welded between the adjacent two overhangs 1.

[0035] More preferably, the starting end and the terminal end of the transverse protection line 2 are fixed between the transverse locking support pipe 5 by anchoring. Figure 4As shown in the figure, the horizontal protection line 2 has two anchoring ends as the starting and ending fixation of the horizontal protection line 2. Further, the inside of the horizontal lock support pipe 5 is designed with a plurality of threading holes 6, and at least two threading holes 6 on each horizontal lock support pipe 5 are arranged in a group, such as 2, 3, 4, etc., and preferably 2 threading holes 6 are arranged in each group. The plurality of threading holes 6 on each horizontal lock support pipe 5 are arranged in a linear arrangement, and the threading holes 6 on two horizontal lock support pipes 5 are arranged in a longitudinal staggered arrangement. During construction, the horizontal protection line 2 is first inserted into the horizontal lock support pipe 5 and passes through two threading holes 6 on one horizontal lock support pipe 5, then passes out of the horizontal lock support pipe 5 and is woven with the longitudinal protection line 3, and then passes through the threading holes 6 on the other horizontal lock. In this way, the ends of the horizontal protection line 2 are anchored and fixed with the horizontal lock support pipe 5.

[0036] In this embodiment, the above starting end anchoring and fixing and the plurality of groups of alternating threading holes 6 ensure good connection of the horizontal protection line 2 with the horizontal lock support pipes 5 at both ends, and ensure tensioning and stability of the horizontal protection line 2.

[0037] Further, an extension plate 7 is provided on one side of each of the overhangs 1. Preferably, two extension plates 7 are provided, which are located on both sides of the reserved hole 4. The purpose of this design is to guide the longitudinal protection line 3 when passing through, and also to facilitate the distinction of the direction of installation of the overhangs 1 when installing a plurality of overhangs 1.

[0038] Better, the horizontal protection line 2 and the longitudinal protection line 3 both use galvanized steel wire. Compared with traditional polyester mesh and low-carbon steel wire mesh, this galvanized steel wire has the advantages of anti-corrosion, anti-aging, economy and beauty. At the same time, the tension of the longitudinal galvanized steel wire can be flexibly controlled by the tensioning force at the beam end.

[0039] Before construction, the construction personnel need to test on site to determine the tensioning force of the longitudinal cable. The control principle of the tensioning force is: tensioning and fastening to avoid excessive deformation of the cable during operation, causing people to fall from the gap, and to avoid excessive tensioning force, causing excessive deformation of the overhang 1, and excessive stress on the steel. Then, the horizontal galvanized steel wire rope and the longitudinal steel wire are woven into a mesh in an up-down staggered manner, and each horizontal steel wire rope and longitudinal cable should be tightly woven and fastened, and slippage is strictly prohibited. The bolts are stainless steel anchors, and each end needs to use a right and left thread double nut fastening, and the embedded steel also needs to use a right and left thread double nut fastening at each end.

[0040] The above detailed description of the specific embodiments of the present application has been made for the purpose of illustrating the purpose, technical solutions and beneficial effects of the present application, and it should be understood that the above is only a specific embodiment of the present application and is not used to limit the protection scope of the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
