Technical Field

[0001] The invention relates to the technical field of bridge construction, in particular to a self-climbing hydraulic turnover formwork for bridge construction. Background Art

[0002] The self-climbing hydraulic formwork for bridge construction is an advanced formwork system and construction process used in the construction of high bridge piers and other structures. It integrates formwork, climbing mechanisms, operating platforms, and auxiliary support and protective components. It aims to solve a series of problems such as formwork support and lifting and personnel operating space during high-altitude bridge construction, and realize efficient, safe and high-quality bridge pier concrete pouring construction.

[0003] However, when the existing self-climbing hydraulic formwork for bridge construction is used, as the scale of bridges continues to expand, the construction height of many bridge piers is increasing. Construction workers often need to perform various construction operations such as steel bar binding, concrete pouring, and formwork installation and removal on high-altitude operating platforms. In the actual construction process, it is inevitable to encounter severe windy weather, and strong winds may cause the operating body to shake violently. The operating platform will shake, become unstable, or even suffer structural damage under the action of strong winds, which will not only prevent the normal construction from being carried out and delay the construction period, but also cause direct impact on the construction workers working on the platform, increasing the risk of people being blown off and injured, causing serious safety accidents, and threatening the lives and health of the construction workers.

[0014] (3) Beneficial effects Compared with the prior art, the present invention provides a self-climbing hydraulic turnover formwork for bridge construction, which has the following beneficial effects: 1. The self-climbing hydraulic formwork for the bridge construction is set up with movable components. When in use, the wind will blow the movable blades and the movable shaft to rotate. When the movable shaft rotates, it will drive the sliding rod, the connecting block and the wind shield at the bottom to move toward the surface close to the main body, thereby realizing merging. When the wind shield slides, the sliding rod will drive the resistance rod to move inside the connecting block and push on the surface of the wind shield, so that the wind shield is merged in an arc shape to prevent the strong wind from blowing directly to the main body without any obstruction in severe windy weather, causing the operating body to shake violently. The movable components can quickly merge to form an effective windproof barrier in strong winds, preventing the strong wind from directly acting on the operating platform and construction personnel, ensuring construction safety, and enhancing the stability of the operating platform.

[0015] 2. The self-climbing hydraulic formwork of the bridge construction is set up with a moving component. When the slide bar slides, it will also drive the fixed bar on the surface of the slide bar to slide. When the fixed bar slides, it will move toward the surface of the support system. When the fixed bar slides, it will also drive the clamping block to clamp on the surface of the support system. Since there must be a plywood inside the clamping block, the support system will resist the plywood. After the resistance is completed, the plywood will be reset under the action of the movable spring, so that the plywood is re-clamped on the surface of the support system for fixation, preventing the support system from shaking in windy weather and affecting the stability of the connection between the support system and the bridge. Long-term shaking will also cause the support system to break or the connection to loosen, thereby enhancing the stability of the connection between the bridge and the support system and reducing safety hazards.

[0016] 3. The self-climbing hydraulic formwork for the bridge construction utilizes a fixed component setting. When the fixed bar slides, it will also drive the sliding of the resistance block. When the resistance block slides, it will move toward the surface of the control block and resist the surface of the control block, causing the control block and the control plate to slide downward. When the control plate slides downward, it will drive the plug-in plate to slide downward, so that the plug-in plate is inserted into the groove opened on the surface of the connecting block, preventing the windshield at the bottom of the connecting block from accidentally dispersing or shifting, and preventing the coordinated work of the movable components from failing, thereby improving the stability and fixing effect of the movable components and improving the reliability of the overall use of the movable components.

[0028] To sum up, the self-climbing hydraulic formwork for bridge construction is mainly composed of a bracket system 3, a hydraulic climbing system 4, an operating platform system 5 and a formwork system 6. The bracket system 3 is used to provide an installation basis for the formwork, and the formwork is fixed to the bracket through connectors to ensure the accurate position of the formwork during concrete pouring and prevent deformation or displacement of the formwork. The hydraulic climbing system 4 is the core power part of the entire formwork to realize the self-climbing function, and generally includes components such as hydraulic cylinders, pump stations, oil pipes, climbing poles (or climbing rails), etc. The hydraulic cylinder is driven by the hydraulic power provided by the pump station to perform telescopic movements, and relies on the interaction with the climbing pole (or climbing rail) to realize the rise or fall of the entire flipping formwork system 6. The operating platform system 5 provides an operating space for construction personnel to facilitate construction operations such as steel bar binding, concrete pouring, formwork installation and removal. At the same time, it also carries some construction materials, tools, etc. to ensure the orderly progress of the construction process. The flipping formwork system 6 includes upper and lower formwork, which are used to pour high pier concrete 2. The formwork is usually composed of multiple units, which are connected into a whole by bolts. Reinforced back ribs and formwork beams are provided on the back to enhance the integrity, rigidity and strength. It can withstand the lateral pressure and other loads of concrete to ensure that the correct shape and size are maintained during the concrete pouring process.

[0029] When the staff encounters severe windy weather during work, the wind will blow the movable blades 73 to rotate. When the movable blades 73 rotate, they will drive the movable shaft 72 to rotate on the outside of the fixed plate 71. When the movable shaft 72 rotates, it will contact the slide rod 74 through the arc groove 720 opened on its surface to move closer to the surface of the body 1. When the slide rod 74 moves, it will drive the connecting block 75 to move on the surface of the operating platform system 5 toward its center point. When the connecting block 75 moves, it will drive the inner windshield 76 to slide on the surface of the operating platform system 5, thereby achieving merging. When the windshield 76 slides, it will also slide on the bottom of the slider 79 and contact the sliding rod 711 at the bottom of the slider 79 through the inclined groove 751 opened on the surface of the connecting block 75 to move closer to the surface of the windshield 76. When the sliding rod 711 moves, it will drive the movement of the resistance rod 712. When the resistance rod 712 moves, it will push on the surface of the wind shield 76. Since the wind shield 76 is made of elastic material, when the resistance rod 712 is pushed, it will merge in an arc shape to prevent the strong wind from blowing directly to the main body 2 without any obstruction in severe windy weather. The strong wind may cause the main body 2 to shake violently, affecting its stability, and even causing damage to the structure of the main body 2. At the same time, strong winds will also cause direct impacts on construction workers working on the platform, increasing the risk of people being blown off and injured. Through the setting of the movable component 7, it can quickly merge to form an effective windproof barrier in strong winds, preventing strong winds from directly acting on the operating platform and construction workers, ensuring construction safety, and enhancing the stability of the operating platform system 5.

[0030] When the movable blade 73 drives the slide bar 74 on the surface of the movable shaft 72 to slide, it also drives the fixed bar 81 on the surface of the slide bar 74 to slide. When the fixed bar 81 slides, it moves toward the surface of the bracket system 3. When the fixed bar 81 slides, it also drives the clamping block 82 to clamp on the surface of the bracket system 3. Because there must be a clamping plate 83 inside the clamping block 82, when the clamping plate 83 inside the clamping block 82 is clamped on the surface of the bracket system 3, the bracket system 3 will resist the clamping plate 83. After the resistance is completed, the clamping plate 83 will return to its original position under the action of the movable spring 84, so that the clamping plate 83 is clamped on the surface of the bracket system 3 again and fixed. The clamping adjustment of bracket systems 3 of different widths can be performed, preventing the bracket system 3 from shaking in strong winds, affecting the stability of the connection between the bracket system 3 and the bridge 1. Long-term shaking can also cause the bracket system 3 to break or the connection to become loose, thereby enhancing the stability of the connection between the bridge 1 and the bracket system 3 and reducing safety hazards.

[0031] When the fixing bar 81 slides, it will also drive the sliding of the interference block 91. When the interference block 91 slides, it will move toward the surface of the control block 93. When the interference block 91 moves to the surface of the control block 93, it will interfere with the surface of the control block 93, so that the control block 93 slides downward inside the block 92. When the control block 93 slides downward, it will drive the control plate 95 to slide downward. When the control plate 95 slides downward, it will drive the plug-in plate 96 to slide downward, so that the plug-in plate 96 is inserted into the groove 750 opened on the surface of the connecting block 75, preventing the wind shield 76 at the bottom of the connecting block 75 from accidentally dispersing or shifting, and preventing the coordinated work of the movable component 7 from failing, thereby improving the stability and fixing effect of the use of the movable component 7 and improving the overall reliability of the use of the movable component 7.
