[0034] The following further describes the present application in detail with reference to the attached Figures 1-5 drawings.

[0035] An embodiment of the present application discloses a safety passage for bridge construction. Referring to Figure 1 , the safety passage for bridge construction includes a step component and a support component. Among them, two sets of step components are provided, and the step component includes a step frame 1 and a step pedal 2 fixedly installed on the step frame 1.

[0036] Specifically, the step frame 1 includes two support frame bodies 101 arranged oppositely. A plurality of step pedals 2 are uniformly arranged from one side of the support frame body 101 to the other side and from bottom to top. Both ends of each step pedal 2 are fixedly installed on one side of the two support frame bodies 101 facing each other. Each support frame body 101 has a vertically arranged installation rod 1011, and the installation rod 1011 is located at one end of the support frame body 101 and is arranged close to the step pedal 2 at a higher position. During use, the bottom of the installation rod 1011 abuts against the top of the concrete beam body to realize the support effect on the support frame body 101.

[0037] Each mounting rod 1011 is rotatably mounted with a reinforcing support rod 3. Specifically, the reinforcing support rod 3 includes a support screw 301, a support rod body 302, and a rotating sleeve 303. Among them, the support screw 301 is rotatably mounted on the mounting rod 1011. One end of the support rod body 302 is provided with a movable groove 4 extending along its own length direction. The rotating sleeve 303 is rotatably mounted at one end of the support rod body 302 where the movable groove 4 is provided. One end of the support screw 301 extends into the movable groove 4 and is in threaded cooperation with the rotating sleeve 303. So that when a force is applied to rotate the rotating sleeve 303, the rotating sleeve 303 drives the support rod body 302 to move in a direction close to or away from the support screw 301, thereby realizing the adjustment of the length of the reinforcing support rod 3. The thread self-locking effect between the support screw 301 and the rotating sleeve 303 is beneficial to ensuring the stability of the reinforcing support rod 3 after the length adjustment. To facilitate applying force to rotate the rotating sleeve 303, the outer peripheral surface of the rotating sleeve 303 is provided with anti-slip lines.

[0038] One end of the support rod body 302 away from the support screw 301 is rotatably mounted with a reinforcing support plate 5. After adjusting the length of the reinforcing support rod 3, rotating the reinforcing support plate 5 so that the reinforcing support plate 5 supports on the ground can further support the position where the mounting rod 1011 is located, which is beneficial to further ensuring the overall stability of the step frame 1. To facilitate folding and storing the reinforcing support rod 3, and thus realizing the movement of the overall structure, the mounting rod 1011 is fixedly mounted with two oppositely arranged elastic clamping rods 6. When the reinforcing support rod 3 rotates to the vertical state, that is, the state where the reinforcing support rod 3 is in contact with the mounting rod 1011, the reinforcing support rod 3 is clamped between the two elastic clamping rods 6.

[0039] There are two sets of support components. The two sets of support components are arranged between the two support frames 101 of the two step components. Specifically, the support component includes two fixed rod bodies 7 and a sliding rod body 8. The two ends of the two fixed rod bodies 7 away from each other are respectively fixedly connected to the mounting rods 1011 of the two support frames. To ensure the connection strength between the fixed rod body 7 and the mounting rod 1011, a reinforcing rib 9 is provided between the fixed rod body 7 and the mounting rod 1011. The two ends of the reinforcing rib 9 are respectively fixedly mounted on the fixed rod body 7 and the mounting rod 1011.

[0040] On one side of the two fixed rod bodies 7 facing the sliding rod body 8, sliding grooves 10 are respectively formed. The two ends of the sliding rod body 8 are respectively inserted and slidably engaged in the sliding grooves 10. In the embodiment of the present application, the cross-sections of the fixed rod body 7 and the sliding rod body 8 are both rectangular. To fully ensure the sliding stability between the sliding rod body 8 and the fixed rod body 7, and at the same time make it difficult for the sliding rod body 8 to slip out of the sliding groove 10 during sliding, a sliding limit groove 11 extending along the length direction of the fixed rod body 7 and communicating with the sliding groove 10 is formed at the top of the fixed rod body 7. A sliding limit rod 12 is slidably engaged in the sliding limit groove 11, and one end of the sliding limit rod 12 is fixedly installed at the top of the sliding rod body 8.

[0041] The sliding rod body 8 is provided with a fixing member for fixing with the fixed rod body 7. Specifically, the fixing member includes a fixing screw 13 disposed in the sliding limit groove 11, and a fixing hole 14 penetrating through the top of the sliding rod body 8 for the fixing screw 13 to pass through. A plurality of threaded holes 15 are formed in the groove wall of the sliding groove 10 on the side facing the sliding limit groove 11 and are evenly distributed along the length direction thereof. When the fixing screw 13 passes through the fixing hole 14 and is in threaded engagement with one of the threaded holes 15, the fixing between the sliding rod body 8 and the fixed rod body 7 is realized.

[0042] A fixed support plate 16 is disposed between the adjacent two fixed rod bodies 7 of the two support assemblies. A plurality of fixed support plates 16 are evenly distributed along the length direction of the fixed rod body 7, and both ends of each fixed support plate 16 are respectively fixedly installed on the adjacent two fixed rod bodies 7 of the two support assemblies to achieve stable support for personnel. A plurality of connection threaded holes 17 are formed in the top of the sliding rod body 8 and are evenly distributed along the length direction thereof. A sliding support plate 18 is further disposed on the top of the sliding rod body 8. The sliding support plate 18 is fixed to the sliding rod body 8 by bolts passing through itself and threadedly engaged with the connection threaded holes 17. The number of the sliding support plates 18 can be specifically set according to the length of the sliding rod body 8 exposed outside the fixed rod body 7. The number of the sliding support plates 18 is not limited herein. After adjusting the distance between the two fixed rod bodies 7, the sliding support plate 18 is arranged on the sliding rod body 8 to further achieve stable support for personnel.

[0043] A protective rod body 19 is further disposed between the adjacent two fixed rod bodies 7 of the two support assemblies. The protective rod body 19 includes a first protective rod 191 and a second protective rod 192. In the embodiment of the present application, there are two first protective rods 191 and second protective rods 192 distributed along the vertical direction. The remote ends of the first protective rod 191 and the second protective rod 192 are respectively fixedly installed on the adjacent two fixed rod bodies 7 of the two support assemblies. The first protective rod 191 passes through the second protective rod 192 and is slidably engaged with the second protective rod 192, so as to protect personnel and play a further limiting role when adjusting the distance between the two fixed rod bodies 7, thereby further ensuring the stability when adjusting the distance between the two fixed rod bodies 7.

[0044] The implementation principle of a bridge construction safety passage in an embodiment of this application is as follows: During use, the two sets of ladder components are respectively placed on the tops of two adjacent concrete beam bodies to complete the erection of the safety passage. When facing two concrete beam bodies with different spacings, the fixing screw 13 is removed from fixing the sliding rod body 8, and the fixing rod body 7 is pulled to enable the sliding rod body 8 to slide within the fixing rod body 7, thereby realizing the adjustment of the overall load-bearing length of the support assembly. After the adjustment of the overall load-bearing length of the support assembly, the position of the sliding rod body 8 can be fixed by screwing the fixing screw 13 so that the fixing screw 13 is threadedly engaged in one of the threaded holes 15, thus realizing the fixation after the adjustment of the overall load-bearing length of the support assembly, facilitating the adaptation to two concrete beam bodies with different spacings, and having strong applicability. At the same time, the fixed support plate 16 installed through the fixing rod body 7 and the sliding support plate 18 installed on the sliding rod body 8 facilitate the stable support of personnel, and have strong safety.

[0045] The above are all preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
