Install the formwork support vertical rod 4: First, weld the base 3 to the back of the guardrail formwork 9, then insert the fixing buckle 44 into the card seat 32 of the base 3, connect the support slideway 1 to the top of the formwork support vertical rod 4 with bolts, slide the sliding buckle 2 into the support slideway 1 from one side, and temporarily block both ends of the support slideway 1.

[0066] 2. Install the concrete fixing vertical rod 5: First, pass the screw rod 510 through the hole reserved in the already poured guardrail 14. One end of the screw rod 510 passes through the first main vertical rod 59 and is screwed into the nut 512 fixed on the first main vertical rod 59. The other end of the screw rod 510 is fixed to the already poured guardrail 14 with a backing plate 511 and a nut 512 to firmly fix the first main vertical rod 59. Install the U-shaped plate 58 on the top of the already poured guardrail 14. The U-shaped end of the U-shaped plate 58 is stuck on the upper edge of the already poured guardrail 14, and the other end of the U-shaped plate 58 is connected and fixed to the fixing plate 57 welded on the first main vertical rod 59 with a pin shaft. Insert the first sleeve rod 54 into the top of the first main vertical rod 59 and fix it with a pin shaft. Install the support slideway 1 and the sliding buckle 2 at the corresponding positions on the top of the first connecting rod 53 with bolts.

[0067] 3. Install the steel bar fixed vertical rod 6: First, place the splint 68 welded to the second main vertical rod 69 outside the guardrail steel bar 8, then place a splint 68 inside the guardrail steel bar 8, and use bolts 67 to connect the two splints 68. It should be noted that the bottom splint 68 is connected to the pre-embedded steel bar of the bridge guardrail, and the installation of the upper splint 68 of the steel bar is the same. Insert the second sleeve rod 64 into the top of the second main vertical rod 69, fix it with a pin shaft, and install the support slideway 1 and the sliding buckle 2 at the corresponding position on the top of the second connecting rod 63 with bolts.

[0068] III. Specific usage method

[0069] During the use process, according to the construction needs, it can be used as a lifeline device during the installation, removal, and concrete pouring of the guardrail formwork 9. When installing the guardrail formwork 9, first install the steel bar fixed vertical rod 6 on the guardrail steel bar 8 that has been welded and fixed on the bridge flange 7, then install the support slideway 1 and the sliding buckle 2. As the guardrail formwork 9 is installed, remove the steel bar fixed vertical rod 6 of the part where the guardrail formwork 9 has been installed, install the formwork support vertical rod 4, and fix the support slideway 1 and the formwork support vertical rod 4. Install the guardrail formwork 9 in this way. Pass the steel wire rope 15 through the first ring 41, the second ring 51, and the third ring 61, and fix both ends to a stable structure with steel wire rope clips 16. Pour concrete into the pouring bin 10. The operators use a double-hook safety belt, one hook is connected to the steel wire rope 15, and the other hook is connected to the sliding buckle 2. The removal of the guardrail formwork 9 is basically the same as the installation, except that the steel bar fixed vertical rod 6 is replaced with a concrete fixed vertical rod 5, and the rest of the operation steps are exactly the same. If the distance between two bridge guardrails is only 50 cm, when installing, removing, and pouring concrete for the guardrail formwork 9, this lifeline device can be fixed to the already poured guardrail 14 on the other side or the guardrail steel bar 8 that has been welded, improving the construction efficiency to a certain extent.

[0070] IV. Quality requirements

[0071] During the welding process, it should be ensured that each rod is horizontal and vertical, and the welding parts are all fully welded. After welding, knock off the welding slag and conduct weld quality inspection to ensure that the weld quality meets the requirements. During the transportation and storage of each component, do not smash or press heavily to prevent deformation of the connecting parts of each component, resulting in difficult installation in the later stage. After the above steps are completed, spray anti-rust materials on this device to improve its durability.
