Abstract
Description
Technical Field
[0001] This utility model relates to the field of tower crane technology for bridge construction, and in particular to a tower crane foundation for installation on an arch bridge. Background Technology
[0002] Tower crane foundations are an important component of tower cranes, used to support and secure the tower crane, ensuring its stability and safety during construction. The design and construction of tower crane foundations must comply with relevant specifications and requirements to ensure the stability of the tower crane under various working conditions.
[0003] A search revealed Chinese patent CN209891238U, which discloses a tower crane foundation. The foundation includes a main body with cantilevered slabs extending outwards from its upper perimeter. A post-cast strip is provided between the cantilevered slab and the basement raft slab. Water-stop steel plates are installed across the junctions of the post-cast strip and the cantilevered slab, and between the post-cast strip and the basement raft slab. This invention avoids the "damage" to the reinforcing steel of the tower crane foundation caused by the arrangement of water-stop steel plates in traditional tower crane foundation designs, thus ensuring the integrity of the reinforcing steel and providing a better load-bearing foundation.
[0004] Based on the above search results combined with existing technologies;
[0005] The aforementioned patented construction method can accurately locate the target on the ground, but it cannot be applied to high-altitude working environments such as arch bridges. If the tower crane foundation legs are installed directly on the arch, there are problems such as difficulty in adjusting the horizontality and verticality, a large number of welds, and difficulty in controlling welding deformation, so it has certain limitations. Utility Model Content
[0006] To address the aforementioned technical problems, this utility model proposes a tower crane foundation for installation on an arch bridge, ensuring the safety of high-altitude operations, avoiding multiple and repetitive welding, and improving construction efficiency.
[0007] The technical solution to achieve the purpose of this utility model is: a tower crane foundation installed on an arch bridge, including a platform support and a foundation platform, wherein the foundation platform is fixedly installed on the surface of the platform support, and also includes connecting components;
[0008] Tower crane foundation, which is fixedly installed on the surface of the foundation platform;
[0009] Multiple connecting components are provided, and each connecting component includes a steel plate disposed on the surface of the tower crane foundation.
[0010] Preferably, multiple stiffening plates are fixedly installed at the bottom of the platform support, multiple reinforcing plates are fixedly installed between the top of the platform support and the bottom of the foundation platform, and multiple reinforcing plates are fixedly installed between the surface of the foundation platform and the tower crane foundation.
[0011] Preferably, a pair of auxiliary inclined beams are fixedly installed on both sides of the tower crane foundation, each of the auxiliary inclined beams is fixedly installed on the surface of the foundation platform, and multiple supporting steels are fixedly installed between the steel plate and the tower crane foundation.
[0012] Preferably, a plurality of threaded rods slide through the steel plate, and a pair of fastening nuts are threadedly connected to both ends of the threaded rods.
[0013] Compared with existing technologies, the significant advantages of this invention are:
[0014] Firstly, this utility model adopts a tower crane foundation for steel pipe arch bridges. By welding, the base can be welded to the upper chord of the main arch rib, which can ensure that the load can be evenly transferred to the upper chord of the main arch rib after the tower crane is installed, thus ensuring the safety of the tower crane operation on the steel pipe arch bridge.
[0015] Secondly, the integrated foundation and platform of this utility model greatly reduces the amount of installation and welding required for tower crane foundations on steel pipe arch bridges, reduces high-altitude operations, makes construction simpler and welding quality better. By controlling the levelness and verticality of the base and tower crane foundation, it is easy to control the installation accuracy of the embedded parts of the tower legs, so that the tower crane foundation for steel pipe arch bridges can be used in high-altitude working environments such as arch bridges.
[0016] This solves the problem that existing construction methods are not applicable to high-altitude working environments such as arch bridges. If the tower crane foundation legs are installed directly on the arch, there are problems such as difficulty in adjusting the horizontality and verticality, a large number of welds, and difficulty in controlling welding deformation.
