Description

TECHNICAL FIELD

[0001] The utility model relates to a caisson technology field, concretely relates to a caisson internal support operation platform. BACKGROUND

[0002] During the caisson construction process, the construction personnel need to perform various work contents such as well wall reinforcement binding and formwork installation inside the caisson, so a safe operation platform needs to be erected inside the caisson to facilitate the construction personnel to stand and walk.

[0003] Since the caisson is an indirect process of pouring a section, excavating a section, and sinking a section, it is difficult to erect a floor type operation platform inside the caisson. The caisson construction is a gradual deepening process, and the work requirements may be different at different stages. The traditional fixed support structure may not be able to adapt to such changes, and frequent replacement or adjustment is required, increasing the construction difficulty and cost. The use of non-reusable or difficult-to-dismount support structures may result in a large amount of materials being discarded after the construction is completed, increasing the construction cost and causing resource waste. SUMMARY

[0004] The utility model aims at providing a caisson internal support operation platform to solve the technical problems pointed out in the background technology.

[0005] To solve the above technical problems, the utility model adopts the technical scheme that:

[0006] A caisson internal support operation platform can be detachably erected inside the caisson, comprising a support platform, the support platform comprising a surrounding steel, a plurality of uniformly spaced horizontal ribs supported horizontally inside the surrounding steel, and a plurality of uniformly spaced vertical ribs supported vertically inside the surrounding steel, the vertical two sides of the inner circumferential wall of the caisson being uniformly provided with a plurality of embedded rod members corresponding to the position of each vertical rib, the bottom of each vertical rib being provided with a socket member allowing the corresponding embedded rod member to be vertically clamped, and each socket member having a downward opening socket.

[0007] Further, the opening side of the socket is provided with a horn opening structure for clamping the embedded rod member.

[0008] Further, the intersection of the horizontal rib and the vertical rib is fixed by welding, and a lifting lifting ring is symmetrically provided on the front and rear horizontal ribs to facilitate the lifting and installation of the operation platform.

[0009] Further, the support platform is divided into a front support platform and a rear support platform, a rotating shaft is rotatably connected between the front support platform and the rear support platform, anti-rotation base blocks are arranged between the support platform and the rear support platform to limit upward rotation, and main shaft lifting rings are symmetrically arranged at both ends of the rotating shaft.

[0010] Furthermore, when the caisson is circular, the surrounding steel is correspondingly set to be circular; when the caisson is square, the surrounding steel is correspondingly set to be square.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This invention designs a detachable and easily installed support platform, effectively solving the problem of the working platform during the construction of caissons and improving construction safety and efficiency. Furthermore, its structural design is reasonable, the installation process is simple, and it is highly flexible in use, making it suitable for the construction of caissons of different shapes and specifications.

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0024] like Figures 1-5As shown, an internal support operation platform for a caisson is detachably erected inside the caisson 1. The platform includes a support platform 3, which comprises a surrounding steel frame 39, several horizontally spaced ribs 31 evenly spaced within the surrounding steel frame 39, and several vertically spaced ribs 32 evenly spaced within the surrounding steel frame 39. Several pre-embedded rods 2 are evenly spaced on both sides of the inner wall of the caisson 1 corresponding to each vertical rib 32. Each vertical rib 32 has a locking member 36 at its bottom, allowing the corresponding pre-embedded rod 2 to be vertically engaged. Each locking member 36 has a downward-facing locking slot 37. The opening side of the locking slot 37 is configured as a flared structure to facilitate the engagement of the pre-embedded rod 2. The junctions of the horizontal ribs 31 and vertical ribs 32 are fixed by welding. Lifting rings 33 are symmetrically arranged on the front and rear horizontal ribs 31 to facilitate the hoisting and installation of the operation platform. The support platform 3 is divided into a front support platform and a rear support platform. A rotating shaft 34 is rotatably hinged between the front support platform and the rear support platform. Anti-rotation base blocks 38 are provided between the support platform and the rear support platform to restrict their upward rotation. Main shaft lifting rings 35 are symmetrically arranged at both ends of the rotating shaft 34.

[0025] When the caisson 1 is circular, the surrounding steel 39 is correspondingly set to be circular; when the caisson 1 is square, the surrounding steel 39 is correspondingly set to be square.

[0026] Specifically, the support platform 3 is composed of circumferential steel 39, horizontal ribs 31, and vertical ribs 32, forming a stable frame structure. The circumferential steel 39 is designed to fit the shape (circular or square) of the caisson 1, ensuring that the platform fits snugly against the inner wall of the caisson. The locking component 36 is located at the bottom of the vertical rib 32, and is vertically engaged with the pre-embedded rods 2 on the inner wall of the caisson through the downward-opening locking slots 37, achieving stable installation of the platform. The lifting ring 33 facilitates the use of lifting equipment to lift the entire support platform into the caisson for precise installation.

[0027] The rotating shaft 34 and the anti-rotation base block 38 divide the support platform into front and rear parts. The rotating shaft 34 enables relative rotation between the two parts, while the anti-rotation base block 38 restricts its upward rotation, ensuring the stability of the platform during operation.

[0028] Installation process:

[0029] Preparation of embedded members: During the construction of caisson 1, members 2 are pre-embedded at designated locations according to the design plan to ensure accurate positioning and uniform spacing.

[0030] Platform assembly: On the ground or in a safe area, the components such as the steel frame 39, horizontal ribs 31, and vertical ribs 32 are assembled into the overall frame supporting the platform 3 by welding or other means, and the bayonet components 36, lifting rings 33, rotating shafts 34, and anti-rotation base blocks 38 are installed.

[0031] Lifting and installation: Using lifting equipment, the support platform is lifted into the caisson 1 as a whole through the lifting ring 33. The position is adjusted so that the clamping component 36 is aligned with the pre-embedded rod 2. Then, the clamping 37 at the bottom of the vertical rib 32 is inserted into the pre-embedded rod 2 to achieve a stable installation.

[0032] Adjustment and Fixing: After installation, make minor adjustments as needed to ensure the support platform is level and stable. If necessary, further reinforce the connection between the platform and the inner wall of the caisson.

[0033] Lifting and disassembly: When it is necessary to disassemble the operating platform, use lifting equipment to lift the entire support platform through the main shaft lifting ring 35. Due to the presence of the pivot 34, the front and rear parts of the support platform can be rotated and folded downwards, which facilitates the disassembly and storage of the operating platform.

[0034] Once installed, the support platform can serve as a platform and support structure for workers to carry out construction operations inside the caisson, providing a stable working environment.

[0035] This invention designs a detachable and easily installed support platform, effectively solving the problem of the working platform during the construction of caissons and improving construction safety and efficiency. Furthermore, its structural design is reasonable, the installation process is simple, and it is highly flexible in use, making it suitable for the construction of caissons of different shapes and specifications.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
