Bridge construction steel frame connecting piece

Abstract

The utility model discloses a bridge construction steel frame connecting piece which comprises two fixing frames and a moving mechanism, and sliding grooves are formed in the side walls of the two fixing frames. When steel frames need to be pre-connected and fixed, a plurality of steel frames are inserted into the inserting grooves in the sliding blocks in the fixing frames at the two ends respectively, then the two fixing frames are in butt joint through the moving mechanism, the steel frames needing to be welded at the two ends are in butt joint, and then the steel frames are welded. A plurality of steel frames are welded after being in butt joint, then the two fixing frames are separated through the moving mechanism, the sliding blocks are limited in the sliding grooves due to the fact that the sliding grooves where the sliding blocks are installed are of structures with the narrow outer portions and the wide inner portions, and therefore the welded steel frames are directly separated from the sliding blocks at the two ends and stripped out from the interiors of inserting grooves; and manual disassembly is not needed, and a plurality of welded steel frames can be separated only by adjusting the double-thread screws.

Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a bridge construction steel frame connector. Background Art

[0002] Steel frames used in bridge construction are core components. They not only support the overall structure of the bridge but also ensure safety and stability during construction. These frames are typically made of high-strength, corrosion-resistant steel, capable of withstanding immense pressure and weight, and adapting to diverse environmental conditions. During bridge construction, the design, manufacture, and installation of steel frames must adhere to strict engineering specifications to ensure the overall quality and long-term stability of the bridge.

[0003] However, in actual bridge construction, it is often encountered that fixed-size steel frames do not meet specific construction requirements. This may be due to the uniqueness of the bridge design or the actual conditions at the construction site deviate from expectations. In this case, two or more standard-sized steel frames need to be connected to adjust their length and structure to ensure that the specific needs of bridge construction are met. In the existing technology, the connection method for bridge steel frames is generally welding or fixing through connecting components. However, connecting components are prone to problems due to disrepair over time and require regular maintenance or replacement. Therefore, in some important application areas, connections are mainly made by welding to ensure the firmness of the connection and stability in long-term use.

The function of the above-mentioned connecting piece is to pre-position the two steel structures before welding. However, if the device is used to weld the steel frames, the two steel frames need to be limited and installed first, and then welded. After welding, the welded steel structures need to be disassembled from the limiting and fixing devices at both ends, and only one pair of steel structures can be welded at a time, which is not efficient and the operation is relatively cumbersome.
