[0002] The elevated parapet is an important and indispensable part in the design of elevated bridges. The elevated parapet usually refers to a low wall or guardrail set on both edges of the elevated bridge. Its main purpose is to provide a physical barrier to prevent vehicles and pedestrians from accidentally falling off the bridge and protect the safety of driving and pedestrians. Especially in the case of vehicle out of control or collision, the parapet can play a role in blocking and decelerating, reducing the severity of the accident. The height of the parapet is generally between 0.8 meters and 1.2 meters, with sufficient strength and stability. Commonly used materials include reinforced concrete and metal guardrails.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and should not be construed as indicating or implying relative importance.

[0018] The present utility model will be further described below in conjunction with the accompanying drawings.

[0019] As Figures 1-3 shown, a rapid installation device for an elevated parapet includes a main beam 1 and four legs 2. The lower end surface of the main beam 1 is connected to the four legs 2. A hoist truck assembly is slidably connected to the main beam 1 for hoisting and installing the parapet. The lower ends of the four legs 2 are each connected to a set of moving components for moving the device. The span of the main beam 1 is 10 m, the width is 3.5 m, and the height is 2 m; the span of the legs 2 is 3.5 m and the height is 5 m.

[0020] The hoist truck assembly includes a movable mounting plate 3. The upper end surface of the movable mounting plate 3 is slidably connected to a motor mounting plate 4. A first motor 5 is connected to the motor mounting plate 4. The output end of the first motor 5 is connected to a winch 6. A lifting rope 7 is connected to the winch 6. The lower end of the lifting rope 7 is connected to a hook 8. The movable mounting plate 3 is slidably connected to the main beam 1. By driving the winch 6 to wind or release the lifting rope 7 through the first motor 5, the parapet hooked by the hook 8 can be lifted or lowered, facilitating installation.

[0021] Both sides of the upper end surface of the main beam 1 are respectively connected to slide rails 9. Each slide rail 9 is connected to a pulley 10. The two ends of the movable mounting plate 3 are respectively connected to a pulley 10. Each pulley 10 is respectively connected to a second motor 11. By driving the pulley 10 to rotate through the second motor 11, the movable mounting plate 3 can move back and forth on the main beam 1, and thus the parapet hoisted by the hook 8 can be driven to move back and forth, facilitating the installation of the parapet.

[0022] One end of the upper end surface of the movable mounting plate 3 is connected to a push cylinder 16. The output end of the push cylinder 16 is connected to the motor mounting plate 4. By the extension and retraction of the push cylinder 16, the motor mounting plate 4 can be driven to move left and right, and thus the parapet hoisted by the hook 8 can be driven to move left and right, facilitating the installation of the parapet.

[0023] The moving component includes moving wheels 12, and the moving wheels 12 are rotatably connected to the lower ends of the support legs 2; a third motor 13 is connected to the side wall of the support leg 2, and the output end of the third motor 13 is connected to the moving wheels 12. By driving the moving wheels 12 to rotate through the third motor 13, the overall movement of the device can be achieved.

[0024] The lower ends of the four support legs 2 are jointly connected to a stabilizing plate 14, and a plurality of stabilizing support cylinders 15 are connected to the lower end surface of the stabilizing plate 14. When hoisting operations are carried out, the support cylinders 15 extend to contact the ground, which helps to improve the overall stability of the device.

[0025] The parapet wall is a precast structure, which is precast on the ground and accurately placed at the predetermined position by the hook of the crane component. Ensure its flatness and stability. Then, the steel bars embedded in the capping beam are tied to the parapet wall, and the lap joint is firm. Pouring concrete is a key step in the construction of the parapet wall. By pouring the steel bars embedded in the box girder into the parapet wall, the parapet wall and the box girder are connected into a whole, and the joint position is filled with concrete. A vibrator is used to vibrate the concrete to ensure its density and strength. After the pouring is completed, the gantry crane moves forward to install the next parapet wall, and the above steps are repeated for positioning, adjustment, fixing, and concrete pouring. Ensure the tight splicing between each component. Using this rapid installation device for the elevated parapet wall to construct the elevated parapet wall is an efficient and safe construction method. Through scientific construction organization, strict quality control, and perfect safety measures, the smooth progress and quality compliance of the parapet wall construction can be ensured. It provides strong support for the overall construction of the viaduct.

[0026] Laying out and positioning are carried out according to the design drawings to determine the specific position and size of the parapet. Measurements and markings are made on the bridge deck to ensure the accuracy of positioning. After the quick installation device for the elevated bridge parapet moves along the track to the designated position on the elevated bridge, the bottom rollers are fixed. The crane assembly moves along the track of the main girder 1, and the prefabricated parapet is lifted and lowered to the designated position by the hook 8 below the crane assembly. Ensure its flatness and stability during the lifting process. Tie the steel bars embedded in the parapet and the capping beam according to the design drawings to ensure that the quantity, specifications, and positions of the steel bars meet the requirements. Pay attention to the lap length and tying firmness of the steel bars during the tying process to ensure the structural strength. Pouring concrete is a key step in the construction of the parapet. Use the quick installation device for the elevated bridge parapet to hoist the concrete mixer to the construction position. After preparing the concrete, carry out the concrete pouring. Use a vibrator to vibrate the concrete to eliminate air bubbles and improve the density and strength of the concrete. After the concrete pouring is completed, curing should be carried out to keep it in a moist state and prevent cracks on the concrete surface. The curing time is generally 7 to 14 days, and the specific time is determined according to the climatic conditions and the requirements of the concrete strength. After the concrete strength reaches the design requirements, remove the formwork. When removing the formwork, it should be removed gently to avoid damaging the concrete surface. After removing the formwork, inspect and trim the parapet to ensure the surface is flat and the dimensions are accurate.

[0027] During the hoisting process, strictly control the weight and height of each hoisting to ensure the safe arrival of the components and prevent overloading operation.

[0028] The quick installation device for the elevated bridge parapet has a unique design, is small and compact in structure, small in size and light in weight, which is convenient for installation and transportation. It has a relatively large span and can adapt to the use requirements of different sites. Strong hoisting capacity: The structure is stable and the hoisting capacity is large, which is suitable for the hoisting and transportation of medium and small-sized goods. High safety: Equipped with a variety of limit and safety protection devices to ensure the safety and reliability of the operation process. Flexible movement: The bottom equipment has steel wheels and can move parallel to the direction of the elevated bridge. Due to its small size and light weight, it can move flexibly to adapt to different working sites and requirements. Large working range: Through its special structure and design, it can cover a large working range and improve work efficiency. Its structure is relatively simple, and the maintenance and repair costs are also relatively low.
