Description

Technical Field

[0001] This utility model relates to the field of tower crane installation technology, and in particular to a steel beam foundation for a bridge pier tower crane. Background Technology

[0002] In bridge construction, tower cranes are typically used for vertical transportation. However, due to the constraints of rivers and the surrounding environment, tower crane installation is quite difficult. The river's normal water level is higher than the top of the bridge pier foundation, and the tower crane foundation needs to be in a dry and stable environment to ensure the normal operation of the tower crane. To speed up bridge construction, it is necessary to ensure the tower crane is operational as soon as possible.

[0003] A search revealed Chinese patent CN216739722U, which discloses a tower crane foundation for bridge construction. The foundation includes a pier cap and a tower crane base located at the edge of the pier cap. The edge of the pier cap has an arc-shaped structure, and the tower crane base comprises a concrete-cast tower crane cap. This tower crane foundation for bridge construction utilizes the edge of the pier cap for construction, with the tower crane base and the edge of the pier cap on the same vertical plane. This method significantly reduces construction costs for steel reinforcement and concrete. Furthermore, the use of steel reinforcement with a diameter ≥28mm ensures a very solid concrete foundation, fully meeting the requirements for the tower crane's bearing capacity and anti-overturning properties. This, in turn, satisfies the requirements for tower crane overturning stability, foundation bearing capacity, and base crack resistance.

[0004] Based on the above search results combined with existing technologies, the findings were as follows:

[0005] While the aforementioned patents guarantee the load-bearing capacity of the device, the complex terrain, topography, and hydrological environment in the Sichuan-Tibet region lead to high engineering construction costs, complex and difficult tower crane installation foundation design, extremely high installation difficulty, and high investment costs. Furthermore, it is difficult to quickly construct tower crane foundations under river water restrictions, thus presenting certain limitations. Utility Model Content

Multiple sets of grouting columns are poured at the bottom of both the high-level and low-level bridge piers. A tower crane steel beam foundation frame is fixedly installed between the high-level and low-level bridge piers. A pair of balance legs are fixedly installed between the low-level bridge pier and the tower crane steel beam foundation frame. The foundation also includes a connecting seat assembly.

[0008] A connecting seat assembly, the connecting seat assembly comprising a plurality of steel plates fixedly installed on the steel beam foundation frame of the tower crane.

[0009] Preferably, a plurality of supporting steel plates are fixedly installed on the surface of the first steel plate, and a third steel plate is fixedly installed on the top of each of the supporting steel plates, and a second steel plate is provided on the third steel plate.

[0010] Preferably, a threaded rod slides through each of the two steel plates and the third steel plate, and multiple raised steel plates are fixedly installed on opposite sides of the two steel plates and the third steel plate. The threaded rod slides through the raised steel plates, and a pair of nuts are threaded to both ends of the threaded rod.

[0012] Preferably, a tower crane foundation section is fixedly installed on the surface of the second steel plate.

[0013] Compared with existing technologies, the significant advantages of this invention are:

[0014] Firstly, this utility model utilizes bridge piers as the foundation support for the tower crane, and sets up balancing steel legs to level the bottom elevation of the tower crane's steel beam foundation. This non-standard steel beam foundation design is suitable for locations near bridge piers that meet the optimal positioning requirements for the tower crane.

[0015] Secondly, this utility model is highly adaptable, has a high turnover rate, is quick to process, efficient to install, and provides stable, safe and reliable support; it reduces the difficulty of tower crane layout and foundation construction, saves costs, and speeds up project progress.

[0026] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0027] This utility model provides an improved steel beam foundation for bridge piers and tower cranes. The technical solution of this utility model is as follows:

[0028] like Figures 1-6 As shown, a bridge pier tower crane steel beam foundation includes a pair of piers 1, one of which has a high pier 2 fixedly installed at its bottom, and the other has a low pier 21 fixedly installed at its bottom. Multiple sets of grouting columns 3 are poured at the bottom of both the high pier 2 and the low pier 21. A tower crane steel beam foundation frame 6 is fixedly installed between the high pier 2 and the low pier 21. A pair of balance legs 8 are fixedly installed between the low pier 21 and the tower crane steel beam foundation frame 6. The construction is strengthened and stabilized by pouring multiple sets of grouting columns 3, reducing losses caused by water flow impact. The installation of balance legs 8 makes the tower crane steel beam foundation frame 6 more stable, balancing the height difference between the high and low piers. The foundation also includes a connecting seat assembly 7.

[0029] The connecting seat assembly 7 includes multiple steel plates 71 fixedly installed on the tower crane steel beam foundation frame 6. The arrangement of multiple steel plates 71 distributes the pressure and provides a foundation for subsequent connections.

[0030] Furthermore, multiple supporting steel plates 9 are fixedly installed on the surface of steel plate 1 71, and steel plate 3 73 is fixedly installed on the top of each supporting steel plate 9. Steel plate 2 72 is set on steel plate 3 73. The structure of the connecting components ensures that the tower crane foundation section 4 to be installed later is in a dry state, so as to avoid affecting the construction progress.

[0031] Furthermore, a threaded rod 75 slides through each of the steel plates 2 72 and 3 73. Multiple raised steel plates 10 are fixedly installed on opposite sides of the steel plates 2 72 and 3 73. The threaded rod 75 slides through the raised steel plates 10. Both ends of the threaded rod 75 are connected to a pair of nuts 74 by threads. The nuts 74 and threaded rod 75 are easy to disassemble and install, which saves material costs, facilitates timely repair and replacement, and improves economic efficiency.

[0032] As a further embodiment of this utility model, multiple stiffening diagonal braces 11 are fixedly installed inside the tower crane steel beam foundation frame 6, and multiple stiffening ribs 5 are fixedly installed between the tower crane steel beam foundation frame 6 and the balance support leg 8. Multiple stiffening ribs 5 are fixedly installed on the outer walls of each balance support leg 8. The installation of stiffening diagonal braces 11 can prevent the tower crane steel beam foundation frame 6 from twisting and deforming. The stiffening ribs 5 improve the load-bearing capacity of the device and enhance its durability.

[0033] Furthermore, tower crane foundation section 4 is fixedly installed on the surface of steel plate 272. Tower crane foundation section 4 provides the necessary support during the operation of the tower crane, improving the safety and reliability of the tower crane.

[0034] The specific working method is as follows: First, complete the pouring of the filling column 3, the low-level pier 21 and the high-level pier 2. Select a suitable position on the pier body 1 above the pier. Second, place a pair of balance legs 8 into the low-level pier 21. Install the tower crane steel beam foundation frame 6 with the pier body 1. Weld the balance legs 8 and the tower crane steel beam foundation frame 6 to reduce the drop and maintain balance. Stiffening ribs 5 are fixedly welded to the four ends of the tower crane steel beam foundation frame 6 and the balance legs 8 to ensure its stability. Then, fix and weld multiple stiffening diagonal braces 11 inside the tower crane steel beam foundation frame 6 to prevent it from twisting and deforming and to maintain its stability. Finally, connect the tower crane foundation section 4 through multiple steel plates on the surface of the tower crane steel beam foundation frame 6, as well as the connecting seat assembly 7 composed of threaded rods 75, nuts 74 and supporting steel 9 on the steel plates, so that the equipment avoids the humid environment and keeps it dry.

[0035] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
