[0002] Large-scale steel structure bridges are generally manufactured and installed in sections due to restrictions on transportation or hoisting conditions. Therefore, large and complex bridges usually require pre-assembly in the factory. Currently, two steel girders are being spliced. The steel girder components are easy to shake, which leads to position deviation. After the bridge splicing is completed, these deviations accumulate and have a great impact on the entire bridge. At the same time, the joints are mostly connected by screws or bolts. In the environment of vibration caused by vehicles to the bridge, the threads on ordinary bolts or screws are easily damaged as the use of the bolts or screws prolongs, resulting in slippage, loosening, and in severe cases, falling off. There is a certain threat to the strength structure of the entire bridge, and there is a great potential safety hazard

The invention discloses a modular steel structure for a high-strength bridge and an installation and construction method, and relates to the field of bridge construction.The modular steel structure comprises a connecting shell, a first space is formed in the connecting shell, and the left end face and the right end face of the connecting shell are each fixedly provided with two connecting and installing blocks; according to the H-shaped steel fixing device, when two pieces of H-shaped steel are fixedly connected, the H-shaped steel can be effectively clamped and positioned through the two corresponding fixing clamping blocks, the H-shaped steel can be fixed and fixed through the fixing clamping blocks, and the H-shaped steel fixing device is convenient to use and high in practicability. The H-shaped steel, the fixing clamping blocks and the shock absorption plates are connected through the shock absorption sliding columns by the shock absorption plates, so that the safety of the connecting position of the two pieces of H-shaped steel is protected by reducing shock generated by running of passing vehicles, and the strength of the connecting position of the two pieces of H-shaped steel is effectively improved.
Description
technical field [0001] The invention relates to the field of bridge construction, in particular to a modular steel structure for a high-strength bridge and an installation and construction method. Background technique [0002] Large-scale steel structure bridges are generally manufactured and installed in sections due to restrictions on transportation or hoisting conditions. Therefore, large and complex bridges usually require pre-assembly in the factory. Currently, two steel girders are being spliced. The steel girder components are easy to shake, which leads to position deviation. After the bridge splicing is completed, these deviations accumulate and have a great impact on the entire bridge. At the same time, the joints are mostly connected by screws or bolts. In the environment of vibration caused by vehicles to the bridge, the threads on ordinary bolts or screws are easily damaged as the use of the bolts or screws prolongs, resulting in slippage, loosening, and in sever...
