Description

Technical Field

[0001] This utility model belongs to the field of bridge pile foundation construction technology, and provides a pile foundation concrete duct construction platform. Background Technology

[0002] Cast-in-place piles are piles constructed by drilling holes in place and pouring in concrete or reinforced concrete. Due to their advantages such as vibration-free construction, no soil displacement, low noise, and suitability for use in densely built-up urban areas, cast-in-place piles are widely used in construction. However, during the concrete pouring construction of land bridge pile foundations, the guide pipe operating platform often lacks effective safety protection measures. The focus is often on the concrete pouring process, neglecting safety, resulting in situations where there are no effective safety protection facilities at the borehole opening, making it easy for workers to fall into the drilled pile, posing a significant safety hazard. Alternatively, materials such as scaffolding are placed horizontally above the steel casing, creating risks of slipping or falling into the pile. Furthermore, some cast-in-place pile platforms have poor operability and low convenience. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a pile foundation concrete pouring duct construction platform with good operability and good on-site construction matching, which aims to provide convenience for duct concrete pouring construction, improve construction efficiency, ensure construction quality, and at the same time greatly improve the safety protection during the concrete pouring process.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] This utility model provides a concrete pouring duct construction platform for pile foundations, including a support frame erected on a steel casing at the top of the pile foundation and a duct frame rotatably mounted on the support frame. The support frame consists of a rhomboid frame, a platform, and a rotating body. The rhomboid frame is installed on the steel casing, the platform is mounted on the rhomboid frame, and the rotating body is mounted on the platform. The duct frame consists of a strip-shaped flat plate and a hinged plate. The strip-shaped flat plate is rotatably connected to the platform via the rotating body. Two hinged plates are connected to the strip-shaped flat plate in a split configuration via hinges. Each of the two hinged plates has a semi-circular slot on its corresponding side, forming a pouring hole adapted to the duct. This design, with its rotatable duct frame, allows workers to easily adjust the position of the duct frame as needed during concrete pouring, improving construction flexibility. The hinged plate design facilitates the operation of the guide pipe, makes concrete pouring easier, and ensures the stability and safety of the guide pipe, preventing displacement of the guide pipe during the pouring process. This design improves the efficiency and quality of construction, making the entire platform easy to operate, safe, and reliable.

[0006] Optionally, connecting struts are provided between the inner sides of each pair of sides of the rhombus frame. These connecting struts help to distribute the load applied to the rhombus frame evenly over a larger area, reduce pressure at each connection point, lower the risk of structural damage, and ensure that it can withstand greater weight during concrete pouring.

[0007] Optionally, a handle is provided on the opening and closing plate. The handle ensures that the operator can maintain a stable grip when operating the opening and closing plate, reducing the risk of slipping or accidental closure, thereby improving operational safety.

[0008] Optionally, the strip plate is equipped with anti-slip ridges. These ridges effectively reduce the risk of workers slipping on the platform, especially during concrete pouring, where splashing concrete or wet surfaces can make the ground slippery; the ridges provide better grip.

[0009] Optionally, the strip-shaped flat plate has checkered steel plates that can slide in and out on both sides along its length. The design of the checkered steel plates can effectively increase the effective area of ​​the construction platform, giving workers more space to operate when pouring concrete and improving the convenience of construction.

[0010] The beneficial effects of this utility model are: the pile foundation grouting concrete duct construction platform of this utility model, by setting up a frame and duct frame with rotatable connection, can not only effectively avoid construction workers from stepping into empty spaces during construction, reduce construction operation risks and avoid unnecessary economic losses, but also make the duct frame relative to the frame adjustable in position, which helps the duct frame adapt to the needs of on-site construction.

Detailed Implementation

[0020] The present invention will be further described below with reference to specific embodiments. The accompanying drawings are for illustrative purposes only, representing schematic diagrams rather than actual physical objects, and should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0021] like Figure 1-6As shown, this utility model discloses a concrete duct construction platform for pile foundation pouring, comprising a support frame 1 erected on a steel casing 3 at the top of the pile foundation and a duct frame 2 rotatably mounted on the support frame 1. The support frame 1 consists of a rhomboid frame 11, a platform 12, and a rotating body 13. The rhomboid frame 11, with its rhomboid shape, effectively distributes the load, improves structural stability, and can be balanced and installed on the steel casing 3 at the top of the pile foundation. The platform 12, mounted on the rhomboid frame 11, provides a stable working surface for the installation of the duct frame 2. This facilitates concrete pouring operations. The rotating body 13 is mounted on the platform 12 and, through a rotatable connection, allows the guide frame 2 to rotate flexibly, facilitating the adjustment of its position relative to the rhomboid frame 11 or the steel casing 3. The guide frame 2 consists of a strip plate 21 and an opening / closing plate 22. The strip plate 21 is rotatably connected to the platform 12 via the rotating body 13, allowing it to rotate at a certain angle. This facilitates the operation and adjustment of the guide frame 2 by the operators. The rotating body 13 uses materials such as bearings or a rotating cylinder, which significantly reduces the friction of the guide frame 2 during rotation. This means that operators require less force when adjusting the position of the guide, thereby improving the convenience and flexibility of operation. Two hinged plates 22 are configured, each connected to the strip plate 21 in a split configuration via hinges 23, allowing for free opening and closing. Each of the two hinged plates 22 has a semi-circular slot on its corresponding side, forming a pouring hole 25 that matches the pouring guide pipe (not shown), ensuring accurate connection and effective concrete pouring during the pouring process. This allows the hinged plates 22 to open and close freely, effectively controlling concrete flow during pouring. In the closed state, the pouring hole 25 in the center is the size of the guide pipe used for pouring pile foundation concrete. The guide pipes are assembled using threaded connections, with protruding ribs at the threaded connections used to secure them to the hinged plates.

[0022] In use, before concrete pouring, the assembled platform is placed on the steel casing of the pile foundation. The opening and closing plate is opened, and the guide pipe is lowered to the appropriate position. The opening and closing plate is then closed to lock the guide pipe in place. As concrete is continuously poured, the depth of the guide pipe needs to be adjusted in a timely manner. The guide pipe is then lifted upwards. During the upward lifting process, the opening and closing plate automatically opens upwards along with the protruding steel ribs of the guide pipe. Subsequently, it is slightly lowered, and the guide pipe is locked at the opening and closing plate. The lifted portion of the guide pipe is then removed. This process is repeated continuously until the concrete pouring is completed, ensuring that the concrete can be evenly and stably filled to the predetermined position, meeting the design requirements. This pile foundation concrete pouring guide pipe construction platform, through reasonable structural design and functional configuration, solves the safety hazards and operational inconveniences existing in traditional construction. It not only improves the construction efficiency of concrete pouring but also effectively ensures the safety of workers, providing reliable technical support for pile foundation construction.

[0023] In this embodiment, connecting struts 14 are provided between the inner sides of each pair of sides of the rhombic frame 11. These connecting struts 14 increase the rigidity of the rhombic frame 11, preventing deformation of the rhombic frame due to external forces during construction, thereby improving the stability of the overall structure.

[0024] In this embodiment, the opening and closing plate 22 is provided with a handle 24, which is made of Φ14 round steel and welded to the steel opening and closing plate 22, making it easy for people to open and close manually. The handle 24 allows the operator to easily open and close the opening and closing plate 22 manually when pouring concrete, making the operation more intuitive and simple, reducing the effort consumed during operation, and improving work efficiency.

[0025] In this embodiment, the strip-shaped flat plate 21 is provided with anti-slip ridges 26. Covering the platform surface with anti-slip ridges reduces the risk of workers slipping and ensures safe and stable operation during concrete pouring.

[0026] In this embodiment, the strip-shaped flat plate 21 has patterned steel plates 27 that can slide in and out on both sides along its length. When the patterned steel plates 27 slide out of the strip-shaped flat plate 21, they can form an additional support structure on the rhomboid frame 11. This support not only increases the stability of the platform but also prevents workers from accidentally falling during operation, providing additional safety protection. When the patterned steel plates 27 slide into the strip-shaped flat plate 21, they can fold in. This design is very practical for handling and storage, making the platform easier to transport and store. In addition, the surface design of the patterned steel plates themselves can increase friction, further improving the stability of workers on the platform and reducing the risk of slipping. Its patterned design can effectively drain water, avoiding slip accidents caused by water accumulation.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
