Description

Technical Field

[0001] The embodiments of this utility model belong to the technical field of work platform technology, and more specifically, relate to a folding and flipping template tie rod removal platform. Background Technology

[0002] Demolition can only proceed when the concrete strength of the pier reaches 2.5 MPa and its surface and edges are guaranteed not to be damaged during demolding. The process involves first removing the positioning bolts, tie rods, locking bolts, and connections between the formwork components. Then, the formwork is loosened using adjusting screws to ensure there is no bond between the formwork and the concrete. Finally, the bottom limiting reinforcement measures and adjusting screws are removed. The formwork is then dismantled using a truck crane and a suspended platform. This demolition method is complex due to the large amount of ground space occupied by the equipment and the use of a suspended platform, posing significant safety hazards.

[0003] Chinese patent CN106829739B discloses a method for dismantling tower crane wall-mounted tie rods using a suspension bridge, comprising the following steps: A. First, fabricate a suspension bridge platform and install it under the tower crane's lifting frame; B. Lower the suspension bridge platform to the lower part of the wall-mounted frame, and fix one end to the main chord of the standard section using two M24 high-strength bolts; C. Lift one end of the suspension bridge, making a 90-degree angle between the suspension bridge platform and the standard section, and tighten the wire rope; D. Unfold the folded platform and fix the end wire rope to one side of the frame; E. Dismantling personnel stand on the suspension bridge platform to dismantle the tower crane's wall-mounted tie rods; F. After removing the wall-mounted tie rods, fold up the platform, suspend the suspension bridge platform parallel to the tower body, and loosen the bolts connecting the suspension bridge platform and the tower crane's standard section; the suspension bridge platform descends with the tower crane's frame. This method facilitates the dismantling of tie rods at higher elevations and utilizes the on-site tower crane, reducing space occupation.

[0004] However, the Chinese patent with publication number CN106829739B, in actual field use, still uses a suspension bridge for installation, and requires maintaining a specific angle during installation. This makes the actual use process more cumbersome and increases the risk of the structure falling during installation. Therefore, a folding and flipping formwork tie rod removal platform is needed to provide a working platform for removing the tie rods on the bridge pier formwork, ensuring the safety of workers while facilitating the removal operation.

[0026] In summary, compared with the prior art, the above-described technical solution conceived by this utility model can achieve the following beneficial effects:

[0027] 1. The template tie rod removal platform of this utility model can achieve the function of folding and flipping by rotating two folding components. When not in use, it can be folded and stored, reducing the occupation of site space and avoiding interference with on-site operations. When needed, it can be fixed to the side of the bridge pier and the first and second folding components can be rotated to unfold it. The operators can move between the two work platforms by climbing the ladder between the two folding components to complete the removal of the tie rod on the template. The operation is convenient and provides a fixed platform to ensure the personal safety of the operators.

[0028] 2. This utility model's template tie rod dismantling platform achieves intelligent folding of the ladder through the precise cooperation of the sliding groove and the slider. The combination of the T-shaped cross-section sliding groove and the dumbbell-shaped slider ensures smooth movement of the ladder during folding, while the bending structure of the limiting groove creates a mechanical self-locking mechanism when unfolded. This double-safety mechanism effectively prevents ladder displacement caused by external forces during operation. Combined with the adjustable support system of the protective plate, operators can adjust the angle of the protective plate according to actual working conditions and achieve multi-level fixing through the adjusting gear array, forming a three-dimensional safety protection system that significantly reduces the risk of falls from heights and provides multiple safety guarantees for dismantling operations.

[0029] 3. This utility model's template tie rod removal platform combines modular design with adaptive adjustment. Through differentiated design of the lengths of the first and second rotating plates and the installation of a sliding groove system with adjusting teeth, the platform can adapt to bridge pier structures of different diameters. This enhances the equipment's versatility and allows workers to freely switch work positions at multiple height levels. Combined with the vertical channels formed by the ladders, it creates a three-dimensional work network, significantly improving tie rod removal efficiency.

[0030] 4. This utility model's template tie rod dismantling platform achieves functional integration through optimized mechanical design. The fixing component adopts a combination of distributed fixing seats and reinforced connecting plates, which both disperses the platform load and enhances structural rigidity. The folding component, through the rational layout of the pivot system, ensures rotational flexibility while utilizing the contact surface between the abutment plate and the fixing plate to form a natural load-bearing support. Combined with the mechanical locking of the limiting blocks, this ensures the platform's stability in the unfolded state. While achieving convenient storage, it maintains a load-bearing capacity comparable to traditional fixed platforms, balancing space economy and operational reliability. Attached Figure Description
