Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, specifically a protective component for the splicing of steel box girders. Background Technology

[0002] A steel box girder is a bridge structure made of welded steel plates forming a closed box-shaped cross-section, named for its box-like appearance. It boasts advantages such as high structural efficiency, strong load-bearing capacity, and aesthetically pleasing design, and is widely used in long-span bridges, urban overpasses, and cross-track bridges. A steel box girder typically consists of a top plate, bottom plate, web, diaphragms, and stiffeners, all connected by full welding to form a closed box-shaped cross-section. The top plate often uses orthotropic bridge deck panels, and stiffeners enhance local stability.

[0003] As indicated by announcement number CN207017133U, a segmented large-span steel box girder is described. This device includes a top plate, a bottom plate, a web, and stiffening ribs. The top plate is horizontally positioned, and the bottom plate is located below it and bent towards the top plate. The web and stiffening ribs are welded and fixed between the top and bottom plates. The long-span steel box girder is 30 meters long and is divided into two segments along its length.

[0004] The aforementioned devices mostly rely on welding at the splicing points during use, which is inefficient, leads to a large workload, delays in construction, and low practicality, failing to meet current market demands. Therefore, we propose a protective component for the splicing points of steel box girders to address the aforementioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a protective component for the splicing of steel box girders, so as to solve the problems mentioned in the background art that the existing devices are mostly welded at the splicing, which is inefficient, leads to a large workload, delays the construction period, has low practicality, and cannot meet the current market demand.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a protective component at the splice of a steel box girder, comprising a first steel box girder, a second steel box girder disposed on the surface of the first steel box girder, and the second steel box girder being spliced ​​and connected to the first steel box girder, wherein a first protective component and a second protective component are disposed on the surface of the first steel box girder and the surface of the second steel box girder.

[0007] Also includes:

[0008] A first connecting component is disposed on the surface of a first protective component and is fixedly connected to the first protective component. A second connecting component is disposed on the surface of a second protective component and is fixedly connected to the second protective component. An installation component is mounted on the surfaces of the first and second connecting components. The installation component includes a connecting plate and is fixedly connected to the first connecting component. A pull rod is mounted on the surface of the connecting plate. A handle is provided at one end of the pull rod and is connected to the pull rod by welding. A groove is formed on the surface of the first and second connecting components. A moving groove is formed on the surface of the groove. A first spring is mounted on the surface of the moving groove. A locking block is provided at one end of the pull rod and is fixedly connected to the pull rod.

[0009] Preferably, the surface of the first protective component is provided with a first connecting block, and the first connecting block is connected to the first protective component by welding.

[0010] Preferably, the surface of the second protective component is provided with a second connecting block, and the second connecting block is fixedly connected to the second protective component.

[0011] Preferably, the surfaces of the first connecting block and the second connecting block are provided with slots, and the surfaces of the slots are provided with transverse grooves.

[0012] Preferably, the surface of the card block is provided with a mounting groove.

[0013] Preferably, a second spring is installed inside the mounting groove, and one end of the second spring is fixedly connected to the inner wall of the mounting groove.

[0014] Preferably, a fixing plate is provided at the other end of the second spring.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention features a handle and a pull rod. Applying force to the handle moves the pull rod. A locking block moves the handle along with the pull rod, causing the locking block to move to one end and into a groove. The protective components are then joined together, and a first spring, when the force applied to the handle and pull rod is released, pushes the locking block into the groove. This allows for rapid installation of the protective components at the steel box girder joint, increasing work speed and efficiency. It significantly improves practicality and overcomes the drawbacks of traditional welding methods, which are inefficient, labor-intensive, and delay construction. Attached Figure Description

[0026] First, a force is applied to the handle 8, causing the handle 8 to move the connected lever 9, which in turn moves the connected locking block 13, moving the locking block 13 into the moving slot 10. Then, the protective components are assembled. Afterward, the force applied to the handle 8 and lever 9 is released, causing the first spring 12 to rebound, thereby pushing the locking block 13 towards the slot 16, so that it can engage with the slot 16 and be fixed.
