Description

Technical Field

[0001] This application relates to the field of cast-in-place pile construction technology, and in particular to a precise positioning platform for cast-in-place piles. Background Technology

[0002] Cast-in-place piles, as an important foundation type, are widely used in high-rise buildings, bridges, rail transit, and other projects. Their construction quality directly affects the structural safety and service life of the entire project, and the positioning accuracy of the cast-in-place piles is one of the key aspects ensuring construction quality. With the increasing precision requirements of engineering projects, traditional positioning methods are no longer sufficient to meet the needs of complex geological conditions and high-precision construction. Therefore, developing an efficient and accurate cast-in-place pile positioning platform has become an urgent need for the industry. This precise positioning platform for cast-in-place piles has emerged in this context. It integrates advanced sensing technology, positioning technology, and intelligent control technology, aiming to achieve real-time accurate positioning during the construction process of cast-in-place piles, providing a solid guarantee for project quality.

[0003] A search revealed that Chinese publication number CN220393060U discloses a hoisting and fixing platform for large-diameter cast-in-place piles with ultra-heavy reinforcing cages. The platform includes a lifting ring for assisting in the hoisting, placement, and fixing of the reinforcing cage, and a positioning structure for positioning and supporting the cage. The positioning structure is fixedly connected below the lifting ring. The lifting ring includes a steel ring, an inner lifting plate fixedly disposed inside the steel ring, an outer lifting plate fixedly disposed outside the steel ring, and a sleeve. Several through holes are provided on the upper and lower end faces of the steel ring, and a gasket and sleeve are fixedly disposed at the outer end of each through hole. This utility model provides a hoisting and fixing platform for large-diameter cast-in-place piles with ultra-heavy reinforcing cages, which can avoid the adverse effects of the pile-forming process on the borehole casing and drilling. By hoisting the reinforcing cage in sections with the lifting ring, it accurately inserts the cage into the hole and fixes it to the positioning structure, ensuring precise positioning and vertical insertion of the reinforcing cage, thus improving the quality of pile formation.

[0004] The patent description mentions that "when placing the reinforcing cage, the centering and fixing of the reinforcing cage can be precisely controlled by the worker operating the movable steel plate, which is simple to operate and has a good fixing effect; the reinforcing cage is hoisted by the lifting ring, which can control the vertical state of the reinforcing cage, improve the quality of the sleeve connection, and ensure that the reinforcing cage is vertically inserted into the hole." However, when placing the reinforcing cage, the contact between the reinforcing cage and the inner wall of the platform can easily cause the platform to shift. In view of the above problems, a precise positioning platform for cast-in-place piles is proposed. Utility Model Content

[0005] The purpose of this application is to provide a precise positioning platform for cast-in-place piles, which aims to improve the problem that the platform is prone to displacement when placing the steel cage.

[0006] The precise positioning platform for cast-in-place piles provided in this application adopts the following technical solution:

[0007] A precision positioning platform for cast-in-place piles includes a long steel beam, a short steel beam fixedly connected to the outside of the long steel beam, a positioning mechanism on the top of the short steel beam, and an anti-deviation mechanism slidably connected inside the long steel beam.

[0008] The anti-deviation mechanism includes a rod, which is slidably connected to the outside of the long steel beam inside. A ring is fixedly connected to the outside of the rod, and a rotating plate is rotatably connected to the outside of the ring. The rotating plate is slidably connected to the outside of the long steel beam inside. A locking assembly is fixedly connected to the outside of the long steel beam.

[0009] Through the above technical solution: the platform is stably supported by long and short steel beams, the positioning mechanism is accurately calibrated, and the anti-deviation mechanism, with its insert rod, ring, and rotating plate working in conjunction with locking components, effectively limits displacement, improves the positioning accuracy of the cast-in-place pile, enhances construction stability, and reduces the risk of deviation.

[0010] Preferably, the positioning mechanism includes multiple vertical channel steels, wherein the bottoms of the multiple vertical channel steels are respectively fixedly connected to the top of the long steel beam and the top of the short steel beam, a steel plate is fixedly connected to the outside of the vertical channel steels, an insert plate is slidably connected to the bottom of the steel plate, an L-shaped plate is fixedly connected to the top of the insert plate, a reinforcing bar is fixedly connected to the inside of the L-shaped plate, and a guide component is fixedly connected to the outside of the insert plate.

[0011] The above technical solution achieves a stable frame by using vertical channel steel and steel plate in the positioning mechanism.

[0012] Preferably, the guide assembly includes a connecting plate, the outside of which is fixedly connected to the outside of the insert plate, a guide rod is fixedly connected to the outside of the vertical channel steel, and the inside of the connecting plate is slidably connected to the outside of the guide rod.

[0014] Preferably, the locking assembly includes a fixing plate, which is externally fixedly connected to the outside of the long steel beam, and a pin is slidably connected internally to the fixing plate, with the pin externally slidably connected to the inside of the rotating plate.

[0018] Preferably, a support plate is fixedly connected to one side of the long steel beam and the short steel beam, and one outer end of the support plate is fixedly connected to the outside of the inclined steel beam.

[0020] Preferably, the top of the long steel beam is fixedly connected with a lifting lug, and both the exterior of the long steel beam and the exterior of the short steel beam are fixedly connected with reinforcing ribs.

[0021] The above technical solutions facilitate the overall hoisting and transportation of the platform, improving construction convenience; the reinforcing ribs enhance the structural strength of the long and short steel beams, resist external deformation, ensure the platform's load-bearing stability, extend its service life, and ensure accurate and reliable positioning of the cast-in-place piles.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. In this utility model, the anti-deviation mechanism achieves vertical anchoring and limiting of the platform by inserting the rod into the soil layer, rotating the rotating plate into the groove of the long steel beam, and inserting the sliding pin into the rotating plate. This process prevents the platform from shifting as a whole during construction, enhances stability, ensures accurate positioning of the cast-in-place piles, avoids affecting the construction quality due to platform displacement, and improves construction reliability and safety.

[0026] 2. In this utility model, the positioning mechanism pulls the reinforcing bar to drive the insert plate to slide, and the guide component assists the insert plate to move, so that the insert plate slides stably into the steel ring cage. This mechanism achieves precise positioning, ensures accurate positioning of the cast-in-place pile, improves construction quality, and is easy to operate, which helps to improve construction efficiency.

[0032] The following combination Figures 1-4 This application will be described in further detail below.

[0033] Example: A precision positioning platform for cast-in-place piles, referring to... Figure 1 , Figure 2 and Figure 4 The system includes a long steel beam 1, which serves as the main load-bearing and supporting foundation structure of the platform, providing longitudinal frame support for the entire positioning platform. The long steel beam 1 is externally fixedly connected to a short steel beam 2, which is interconnected with the long steel beam 1 to form the transverse frame of the platform. Together with the long steel beam 1, they form a rectangular frame structure. The top of the short steel beam 2 is equipped with a positioning mechanism 3, and the inside of the long steel beam 1 is slidably connected with an anti-deviation mechanism 4.

[0034] The anti-deviation mechanism 4 includes a rod 41, the bottom of which can be inserted into the foundation such as the soil layer of the construction site to limit the platform vertically and prevent the platform from shifting as a whole during the construction of the cast-in-place piles. This provides vertical anchoring for the platform and enhances its stability. The rod 41 is externally slidably connected to the inside of the long steel beam 1, and a ring 42 is fixedly connected to the outside of the rod 41. The ring 42 mainly serves to connect the rotating plate 43 and provides a ring-shaped connection base for the rotation of the rotating plate 43. The rotating plate 43 is rotatably connected to the outside of the ring 42. During platform installation, the rod 41 can be better inserted into the soil layer and fixed by operating the rotating plate 43. The rotating plate 43 is externally slidably connected to the inside of the long steel beam 1, and a locking component 44 is fixedly connected to the outside of the long steel beam 1.

[0035] Specifically, the bottom of the insertion rod 41 is aligned with the target position of the soil layer at the construction site. The insertion rod 41 is pushed downward so that its bottom is inserted into the soil layer. The outer ring 42 of the insertion rod 41 moves synchronously with the insertion rod 41. The rotating plate 43 is rotated so that it rotates outside the ring 42 and slides into the long steel beam 1. The pin 442 slides inside the fixing plate 441 so that the pin 442 is inserted into the rotating plate 43, thus fixing the rotating plate 43 and fixing the insertion rod 41.

[0036] Reference Figures 1 to 3 The locking component 44 includes a fixing plate 441, which serves as the mounting base for the pin 442, providing a sliding guide and support structure for the pin 442. The fixing plate 441 is externally fixedly connected to the outside of the long steel beam 1, and the pin 442 is slidably connected inside the fixing plate 441. Under the guidance of the fixing plate 441, the pin 442 can be inserted into the corresponding position of the rotating plate 43 to lock the position of the rotating plate 43. The pin 442 is externally slidably connected to the inside of the rotating plate 43. The positioning mechanism 3 includes multiple vertical channel steels 31, which are respectively fixedly connected to the top of the long steel beam 1 and the top of the short steel beam 2, and are the basic support components of the positioning mechanism 3. The bottom of the multiple vertical channel steels 31... The vertical channel steel 31 is fixedly connected to the top of the long steel beam 1 and the top of the short steel beam 2 respectively. The external of the vertical channel steel 31 is fixedly connected to the steel plate 32, which serves as a connection and auxiliary support. The bottom of the steel plate 32 is slidably connected to the insert plate 33. The insert plate 33 limits the position of the steel reinforcement cage 35 by changing its own position. The top of the insert plate 33 is fixedly connected to the L-shaped plate 34, which provides an installation foundation for the steel reinforcement 35. The inside of the L-shaped plate 34 is fixedly connected to the steel reinforcement 35, which makes it easy for workers to pull out the steel plate 32. The external of the insert plate 33 is fixedly connected to the guide component 36. The external of the insert plate 33 is slidably connected to the outside of the vertical channel steel 31, and the bottom of the insert plate 33 is slidably connected to the top of the short steel beam 2.

[0037] The guide assembly 36 includes a connecting plate 361, which serves as a connecting component between the insert plate 33 and the guide rod 362, linking the sliding of the insert plate 33 with the guiding function of the guide rod 362. The connecting plate 361 is externally fixedly connected to the outside of the insert plate 33, and the guide rod 362 is externally fixedly connected to the outside of the vertical channel steel 31. The guide rod 362 provides a guide track for the sliding of the insert plate 33, and the inside of the connecting plate 361 is slidably connected to the outside of the guide rod 362.

[0038] Specifically, by pulling the reinforcing bar 35, the insert plate 33 is slid outside the vertical channel steel 31. Then, the steel ring cage is hoisted into the platform. Next, the reinforcing bar 35 pushes the insert plate 33 into the steel ring cage. During the movement of the insert plate 33, the guide component 36 provides guidance for the insert plate 33. The connecting plate 361 slides along the guide rod 362, allowing the insert plate 33 to move under the constraint of the vertical channel steel 31 and the short steel beam 2. After the positioning preparation is completed, the cast-in-place pile construction can be carried out.

[0039] Reference Figure 1 and Figure 2 The long steel beam 1 is externally fixedly connected to an inclined steel beam 5. The inclined steel beam 5 serves to strengthen the connection between the long steel beam 1 and the short steel beam 2 and to improve the overall structural stability. The inclined steel beam 5 is externally fixedly connected to the outside of the short steel beam 2. The bottom of multiple vertical channel steels 31 is fixedly connected to the top of the inclined steel beam 5. A support plate 6 is fixedly connected to the adjacent side of the long steel beam 1 and the short steel beam 2. The support plate 6 mainly serves to provide auxiliary support and connection, further strengthening the connection between the long steel beam 1, the short steel beam 2 and the inclined steel beam 5. One end of the support plate 6 is fixedly connected to the outside of the inclined steel beam 5. A lifting lug 7 is fixedly connected to the top of the long steel beam 1. The lifting lug 7 is mainly used for the hoisting and transportation of the positioning platform. Reinforcing ribs 8 are fixedly connected to the outside of both the long steel beam 1 and the short steel beam 2. The reinforcing ribs 8 enhance the local strength and overall rigidity of the steel beam, preventing excessive bending and deformation of the steel beam when it is under load.

[0040] Specifically, using the lifting lugs 7 on the top of the long steel beam 1, the platform is lifted and moved to the construction position by a lifting device. The inclined steel beam 5 on the outside of the long steel beam 1 is connected to the outside of the short steel beam 2. The bottom of multiple vertical channel steels 31 is placed on the top of the inclined steel beam 5. One end of the support plate 6 on the side of the long steel beam 1 and the short steel beam 2 is connected to the outside of the inclined steel beam 5. The reinforcing ribs 8 on the outside of the long steel beam 1 and the short steel beam 2 are placed in place along with the steel beams to ensure that the platform remains stable in subsequent operations.

[0041] The implementation principle of this application embodiment is as follows: When using the precise positioning platform for cast-in-place piles, the platform is first hoisted to the construction site using the lifting lug 7 with the help of the lifting equipment, so that the insertion rod 41 is aligned with the position to be inserted into the soil layer. After the insertion rod 41 is inserted into the soil layer, the rotating plate 43 is operated to rotate the rotating plate 43 into the groove inside the long steel beam 1. Then the sliding pin 442 slides in the fixed plate 441, so that the pin 442 is inserted into the rotating plate 43, and the insertion rod 41 is locked using the locking component 44.

[0042] By pulling the reinforcing bar 35, the insert plate 33 is slid outside the vertical channel steel 31. Then, the steel ring cage is hoisted into the platform. Next, the reinforcing bar 35 pushes the insert plate 33 into the steel ring cage. During the movement of the insert plate 33, the guide component 36 provides guidance for the insert plate 33. The connecting plate 361 slides along the guide rod 362, allowing the insert plate 33 to move under the constraint of the vertical channel steel 31 and the short steel beam 2. After the positioning preparation is completed, the cast-in-place pile construction can be carried out.

[0043] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
