Description

Technical Field

[0001] This utility model relates to the field of high-pile wharf tower crane construction technology, specifically a tower crane foundation structure. Background Technology

[0002] Tower cranes require foundations during installation, typically by embedding fixed legs in concrete to ensure safe operation.

[0003] In some situations, such as the construction of offshore high-pile wharves, the foundation of offshore wharves is mostly pile foundation or soft soil. The onshore foundation may not be able to provide sufficient bearing capacity, affecting the stability of the tower crane; the tower crane installed on the shore may not be able to reach the required height, making it difficult to complete high-altitude operations; and it cannot cover the construction area far from the shore, affecting the later construction. Therefore, it is necessary to provide a tower crane foundation structure to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a tower crane foundation structure that solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: a tower crane foundation structure, including a high-pile wharf concrete main structure and a tower crane fixed leg, wherein a pre-embedded connector is pre-embedded inside the high-pile wharf concrete main structure, and the tower crane fixed leg is pre-embedded in the high-pile wharf concrete main structure and located at the upper end of the pre-embedded connector, and the upper end of the tower crane fixed leg extends out of the high-pile wharf concrete main structure.

[0006] Preferably, the lower end of the tower crane fixed leg is provided with a connecting flange, the pre-embedded connector is a pre-embedded anchor bolt, and the lower end of the tower crane fixed leg is connected to the pre-embedded anchor bolt through the connecting flange.

[0007] Preferably, the connecting flange is provided with fixing bolts, and the connecting flange is fixedly connected to the pre-embedded anchor bolts by fixing bolts.

[0008] Preferably, the main concrete structure of the high-pile wharf is a concrete pile cap, and the tower crane fixed legs are provided with four, which are respectively pre-embedded in the four corners of the concrete pile cap.

[0009] Preferably, a pile post is provided at the lower end of the concrete pile cap, and the upper end of the pile post extends into the interior of the concrete pile cap.

[0010] Preferably, the main concrete structure of the high-pile wharf is a concrete beam, and protrusions are provided on both sides of the upper surface of the concrete beam. The tower crane fixed legs are embedded on both sides of the concrete beam.

[0011] Preferably, the upper end of the tower crane fixed leg extends outward with a boss, and both ends of the concrete beam are provided with I-beams, which penetrate through the concrete beam where the tower crane fixed leg is located.

[0012] Preferably, both ends of the concrete beam where the tower crane's fixed legs are located are provided with double-layered I-beams, and both ends of the I-beams are respectively connected to the beam structures on both sides of the concrete beam where the tower crane's fixed legs are located.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The tower crane foundation structure, with pre-embedded connectors within the concrete main structure of the high-pile wharf, consists of pre-embedded anchor bolts. These anchor bolts are connected to the tower crane's fixed legs via connecting flanges and fixing bolts, forming a unified structure. This achieves a rigid connection between the tower crane's fixed legs and the concrete main structure of the high-pile wharf, utilizing the pile foundation of the high-pile wharf to bear the tower crane's load, enabling rapid installation and stable operation. When the concrete main structure of the high-pile wharf is a concrete beam, protrusions are provided to effectively increase the height of the beam, ensuring the deep embedment of the tower crane's fixed legs. Double-layered I-beams further enhance the stability of the concrete beam containing the tower crane's fixed legs, connecting it to the beams on either side.

[0015] 2. The tower crane foundation structure, with its fixed outriggers embedded in the high-pile wharf's concrete main structure, forms a rigid connection between the tower crane and the wharf structure, enhancing the overall structural stability and load-bearing capacity. This avoids the overturning or displacement risks associated with traditional independent tower crane foundations. Furthermore, the embedded outriggers eliminate the need for separate foundations within the wharf's concrete main structure, optimizing space utilization, especially suitable for wharf areas with limited space. By rationally designing the placement of the fixed outriggers, the operating range is expanded, covering more construction areas, particularly addressing the hoisting needs on the wharf's shoreline, thus compensating for the insufficient coverage of floating cranes. Compared to floating cranes, tower crane construction reduces the impact of water level changes on construction, reduces fuel consumption and carbon emissions, and is more environmentally friendly.

The tower crane fixed leg 3 is pre-embedded in the high-pile wharf concrete main structure and is located above the pre-embedded connector. The upper end of the tower crane fixed leg 3 extends out of the high-pile wharf concrete main structure.

[0024] The tower crane fixed leg 3 is equipped with a connecting flange 301 at its lower end. The pre-embedded connecting part is a pre-embedded anchor bolt. The lower end of the tower crane fixed leg 3 is connected to the pre-embedded anchor bolt through the connecting flange 301. The connecting flange 301 is equipped with a fixing bolt. The connecting flange 301 is fixedly connected to the pre-embedded anchor bolt through the fixing bolt. By setting the connecting flange 301 and the fixing bolt, it can be effectively connected to the pre-embedded anchor bolt to form an integral whole, realizing the rigid connection between the tower crane fixed leg 3 and the concrete pile cap 1, and ensuring the stability of the tower crane fixed leg 3.

[0025] Among them, the main concrete structure of the high-pile wharf is a concrete pile cap 1, and four tower crane fixed legs 3 are set. The four tower crane fixed legs 3 are respectively embedded in the four corners of the concrete pile cap 1. A pile column 4 is set at the lower end of the concrete pile cap 1, and the upper end of the pile column 4 extends into the interior of the concrete pile cap 1. Since the upper end of the pile column 4 extends into the interior of the concrete pile cap 1, the stability of the concrete pile cap 1 can be effectively guaranteed, thereby ensuring the stability of the embedded tower crane fixed legs 3.

[0026] Working principle: The upper end of the pile 4 extends into the concrete pile cap 1, which can effectively ensure the stability of the concrete pile cap 1. The concrete pile cap 1 is pre-embedded with anchor bolts. By setting the connecting flange 301 and fixing bolts, it can be effectively connected with the pre-embedded anchor bolts to form an integral whole, realizing the rigid connection between the tower crane fixed leg 3 and the concrete pile cap 1, ensuring the stability of the tower crane fixed leg 3. The pile foundation of the high pile wharf is used to bear the tower crane load, realizing the rapid installation and stable operation of the tower crane.

The tower crane fixed legs 3 are embedded on both sides of the concrete beam 2. The upper end of the tower crane fixed legs 3 extends out of the protrusions 201. I-beams 5 are provided at both ends of the concrete beam 2. The I-beams 5 penetrate through the concrete beam 2 where the tower crane fixed legs 3 are located. By providing protrusions 201, the concrete beam 2 can be locally heightened, ensuring that the tower crane fixed legs 3 are deeply embedded and improving the stability of the tower crane fixed legs 3.

[0031] Among them, the concrete beam 2 where the tower crane fixed leg 3 is located is equipped with double-layer I-beams 5 at both ends. The two ends of the I-beams 5 are connected to the beam structures on both sides of the concrete beam 2 where the tower crane fixed leg 3 is located.
