Description

Technical Field

[0001] This utility model relates to the field of cast-in-place continuous beam technology, and in particular to a synchronous operation platform for the exterior finish of cast-in-place continuous beams. Background Technology

[0002] In the construction of cast-in-place continuous beams, the concrete pouring process has a crucial impact on the project quality. However, due to the complex construction environment and cumbersome operating procedures, concrete is highly susceptible to defects such as honeycomb, pitting, and cracks caused by insufficient vibration, improper control of pouring speed, and inadequate curing measures. These defects not only affect the appearance of the bridge but also weaken the structure's durability and safety. Therefore, construction personnel need to conduct close-range, meticulous inspections of the concrete's density and surface smoothness, and promptly carry out surface finishing, curing, and defect repair. Surface finishing involves fine operations such as smoothing and roughening; curing requires frequent application of moisturizing materials or regular water spraying; and defect repair requires targeted measures for different problems. The entire process is time-consuming and labor-intensive, demanding extremely high levels of technical skill and responsibility from the construction personnel.

[0003] Traditional exterior finishing work platforms have numerous insurmountable drawbacks when addressing these issues. To accommodate work at varying heights, these platforms typically employ a multi-layered structure, resulting in excessive overall weight. This not only increases the difficulty of installation and dismantling but also places additional loads on the bridge structure, posing safety hazards. Furthermore, workers must frequently move between platforms carrying heavy repair tools, significantly consuming physical strength, extending work time, reducing efficiency, and increasing the risk of falls due to height. In addition, the cumbersome switching between multi-layered platforms makes it difficult to conduct defect repairs at different heights continuously, further impacting construction progress and repair quality, and failing to meet the demands of modern bridge construction for efficient, safe, and high-quality work. Summary of the Invention

[0004] The purpose of this utility model is to provide a synchronous operation platform for the exterior finishing of cast-in-place continuous beams, so as to solve the problems existing in the prior art.

[0009] In one possible implementation, the inner and outer tracks are provided with a plurality of locking holes spaced apart in the vertical direction; when the inner and outer tracks are in a stationary state, the inner and outer tracks are locked by locking bolts to prevent the lower platform from sliding.

[0010] In one possible implementation, the lifting device is a hand-operated hoist.

[0011] In one possible implementation, the hook end of the chain hoist is connected to the lower platform via a first lifting lug, and the lifting chain end of the chain hoist is connected to the upper platform via a second lifting lug.

[0012] In one possible implementation, the upper platform is fixed to the cast-in-place continuous beam equipment by steel sections.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "multiple" means two or more.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Figure 1 This diagram illustrates the installation principle of a synchronous operation platform for the exterior finishing of cast-in-place continuous beams, provided in an exemplary embodiment of the present invention. The synchronous operation platform 1 is mounted on the cast-in-place continuous beam equipment 2. (Please refer to...) Figures 2 to 5 The synchronous operation platform 1 for the exterior finish of the cast-in-place continuous beam includes: an upper platform 11, which is fixed to the cast-in-place continuous beam equipment 2 to move synchronously with the cast-in-place continuous beam equipment 2; and a lower platform 12, which is connected to the upper platform 11 by a connecting rail 13 and a lifter 14; wherein the connecting rail 13 includes an outer rail 131 fixed to the upper platform 11 and an inner rail 132 fixed to the lower platform 12, and the inner rail 132 is slidably connected to the outer rail 131.

[0027] In one example, the upper platform 11 is fixed to the cast-in-place continuous beam equipment 2 by steel sections.

[0028] In one example, there are two connecting tracks 13, located near the ends of the upper platform 11 and the lower platform 12, respectively.

[0029] In one example, there are two elevators 14, located near the ends of the upper platform 11 and the lower platform 12, respectively.

[0030] In this embodiment, the upper platform 11 is rigidly fixed to the cast-in-place continuous beam equipment 2 by steel profiles and moves synchronously with the equipment to provide a stable base. The lower platform 12 relies on the connecting rails 13 to form a sliding fit with the upper platform 11. The outer rail 131 is fixed to the upper platform 11, and the inner rail 132 connects to the lower platform 12. The nested sliding structure provides guidance for lifting and lowering, and the symmetrical lifting devices 14 at both ends apply force synchronously to achieve smooth lifting and lowering. In this case, the double connecting rails 13 are placed at both ends to distribute the weight and prevent deformation, ensuring the straightness of lifting and lowering; the double lifting devices 14 adjust the height evenly to adapt to different operation requirements; the linkage mode of the upper platform moving with the cast-in-place continuous beam equipment 2 and the lower platform lifting and lowering flexibly, combined with the rail constraints, allows workers to work continuously without frequently moving the platform, ensuring operational safety and the synchronization of repair and pouring.

[0031] As existing technology, the cast-in-place continuous beam equipment 2 is a specialized large-scale complete set of equipment used for the construction of cast-in-place continuous beams for bridges. It mainly consists of a support system, a formwork system, a walking system, and auxiliary operating devices. Its core function is to provide a stable working platform and forming framework for concrete pouring. The formwork system defines the structural form of the continuous beam, the support system bears the self-weight of the concrete and construction loads, and the walking system drives the entire equipment to move gradually along the bridge axis, enabling continuous operation of segmented pouring of the continuous beam. During construction, this equipment must be precisely positioned according to the design elevation and alignment to ensure the orderly progress of concrete pouring, curing, and other stages. It is a key piece of equipment for achieving structural forming and progress advancement in the construction of cast-in-place continuous beams.

[0032] In some embodiments, please refer to Figures 2 to 5 The lower platform 12 is equipped with guardrails 15 on all four sides; the upper platform 11 is equipped with guardrails 15 on three sides, but no guardrails 15 are installed on the left or right side of the upper platform 11.

[0033] In other embodiments, please refer to Figures 2 to 5 The upper platform 11 and the lower platform 12 are equipped with guardrails 15 on all four sides. The guardrails 15 on the left or right side of the upper platform 11 are openable guardrails.

[0034] In this embodiment, the lower platform is equipped with guardrails 15 on all four sides. Since workers need to move around the entire platform during operation, the fully enclosed design can prevent accidental falls and reduce the risk of falling from heights. The upper platform is equipped with guardrails 15 on three sides, with no guardrails on the left or right side, or the corresponding side is an openable guardrail, which is to reserve passage for workers to go up and down.

[0035] Specifically, please refer to Figures 2 to 5 A retaining ring is installed between the inner rail 132 and the outer rail 131 to prevent the inner rail 132 and the outer rail 131 from separating laterally or longitudinally during movement due to uneven force, vibration or operational deviation.

[0036] In this embodiment, the retaining ring is installed at the nested contact point of the two tracks, and its size is precisely matched with the track gap. Its structure can fill the tiny gaps when the tracks slide. When the inner track 132 moves relative to the outer track 131, the retaining ring can slide synchronously along the track contact surface, forming a continuous radial constraint. In this case, on the one hand, it can counteract the lateral offset force caused by construction vibration and uneven force distribution, preventing lateral misalignment of the tracks; on the other hand, it can limit longitudinal movement, preventing the track ends from detaching due to operational deviations. Simultaneously, the rigid contact of the retaining ring can reduce track sway, ensuring the stability of the lower platform 12 during lifting and lowering, providing double protection for operational safety.

[0037] For more details, please refer to Figures 2 to 5 Multiple locking holes 133 are provided at intervals along the vertical direction on the inner track 132 and the outer track 131. When the inner track 132 and the outer track 131 are in a stationary state, the inner track 132 and the outer track 131 are locked by locking bolts 134 to prevent the lower platform 12 from sliding.

[0038] In this embodiment, the vertically spaced locking holes 133 can be flexibly matched according to the required height of the lower platform 12. When the inner rail 132 moves to the target position relative to the outer rail 131, the corresponding locking holes 133 align, and the locking bolts 134 are inserted into the holes to form a rigid connection. In this case, mechanical locking ensures that the inner and outer rails do not slip relative to each other in a static state, providing stable support for the lower platform 12 and preventing accidental settlement of the platform due to construction vibration or load changes. The spaced arrangement of multiple sets of locking holes 133 can meet the fixing requirements of different working heights and achieve precise positioning in conjunction with the lifting device 14.

[0039] In some embodiments, please refer to Figures 2 to 5 The lifting device 14 is a manual chain hoist. The hook end of the manual chain hoist is connected to the lower platform 12 through the first lifting lug 16, and the lifting chain end of the manual chain hoist is connected to the upper platform 11 through the second lifting lug 17.

[0040] In this embodiment, the hand-operated hoist is connected to the first lifting lug 16 of the lower platform 12 via its hook end, and to the second lifting lug 17 of the upper platform 11 via its lifting chain end, forming a vertically suspended structure. Utilizing the internal gear transmission principle of the hoist, workers can manually pull the chain to raise and lower the lower platform 12, and it can be suspended at any height via its self-locking function. In this case, the rigid connection between the lifting lug and the hoist can distribute the load, ensuring stable force transmission during raising and lowering and preventing platform tilting; the manual operation of the hand-operated hoist is flexible and controllable, allowing for precise adjustment of the height of the lower platform 12 to meet different repair work needs; its self-locking function, combined with the locking hole 133 and locking bolt 134, provides double protection for the stability of the platform when it is stationary, reducing safety hazards.

[0041] Next, combined Figures 1 to 5 The working principle of the synchronous operation platform for the exterior finish of cast-in-place continuous beams involved in the embodiments of this utility model is explained.

[0042] First, when the cast-in-place continuous beam equipment 2 is advanced along the construction direction and concrete is poured, the synchronous operation platform 1 is pre-assembled on the ground and then hoisted to a designated position that matches the pouring height of the continuous beam by a tower crane. Then, the upper platform 11 is rigidly connected and fixed to the cast-in-place continuous beam equipment 2 using steel sections to ensure that the platform can move synchronously with the equipment and achieve real-time connection with the concrete pouring process. Secondly, when adjusting the height of the lower platform 12, the operation process of unlocking first, then raising and lowering, and then locking must be strictly followed. Before raising and lowering, the locking bolts 134 on the connecting rail 13 must be removed to release the rigid constraint between the inner rail 132 and the outer rail 131, so as to reserve space for the sliding of the lower platform 12 and avoid the lifting and lowering being obstructed due to the locking bolts 134 jamming. Finally, after the lower platform 12 is adjusted to the required working height by the lifting device 14, the locking bolt 134 must be immediately inserted into the corresponding locking hole 133 and tightened. The mechanical locking ensures that the inner and outer tracks are relatively fixed, preventing the lower platform 12 from slipping unexpectedly due to construction vibration or load changes. This provides a safe and stable operating base for workers to carry out exterior surface repair work on the lower platform, ultimately achieving exterior surface defect repair synchronously with the continuous beam pouring.

[0043] In summary, the synchronous operation platform for exterior finishing of cast-in-place continuous beams provided by this technical solution is installed on the cast-in-place continuous beam equipment. It includes an upper platform fixed to the equipment to move synchronously with it, and a lower platform connected to the upper platform via connecting rails and a lifting device. The connecting rails include an outer rail fixed to the upper platform and an inner rail fixed to the lower platform, with the inner and outer rails slidably connected. In this configuration, the synchronous operation platform is suitable for repairing the exterior finish of most continuous beams, is easy to operate, can quickly and accurately repair defects, ensures structural durability and appearance quality, shortens working time, improves efficiency, and reduces safety hazards.

[0044] In the embodiments disclosed in this utility model, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments disclosed in this utility model according to the specific circumstances.

[0045] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
