Ultra-wide steel box girder component of a bridge and a water splicing method thereof

Abstract

The invention relates to an ultra-wide steel box girder component of a bridge. The ultra-wide steel box girder component of the bridge includes a main body unit and a flank unit pivotally connected with that main body unit, and the flank unit naturally drops and is located on both sides of the main body unit under the action of its gravity. The invention relates to a water splicing method of ultra-wide steel box girder component of the bridge includes 1. the ship transports the oversized members of the wing unit down to the area to be installed; 2, that support is erect and welded on the top surface of the main body unit of the box gird component; 3, the inverted chain is passed through the upper hanging lug and the lower hanging lug; 4, the side wing unit is rotated to the splice positionby the inverted chain, and then locking the inverted chain to weld the side wing unit and the main body unit; Step 5, the brackets are detached, and the transportation of the ultra-wide components and the assembly on the water are completed. The invention solves the problems of the ultra-wide box girder component passing through the sluice gate and assembling on the water, hereby reducing the useof large-scale machinery, reducing the construction site requirements; guaranteeing construction quality, and speeding up construction speed and saving cost.

Description

technical field [0001] The invention relates to a steel structure bridge, in particular to an ultra-wide steel box girder member of the bridge. Background technique [0002] Steel is light and high-strength, and steel structure bridges have greater spanning capacity than concrete bridges; and steel structure processing is fast, so steel structures are widely used in long-span bridge structures. [0003] However, during the transportation of ultra-wide steel box girder components, if the width of the sluice along the line or the distance between the bridge piers along the line is small, the large steel box girder components will be super wide and difficult to transport; even if the ultra-wide components are disassembled into multiple units for transportation , but after being transported to the destination, it is necessary to complete the assembly and welding. Because the shaking of the ship is not convenient for construction, if it is hoisted to the shore for construction, i...

[0003] However, during the transportation of ultra-wide steel box girder components, if the width of the sluice along the line or the distance between the bridge piers along the line is small, the large steel box girder components will be super wide and difficult to transport; even if the ultra-wide components are disassembled into multiple units for transportation , but after being transported to the destination, the assembly and welding still needs to be completed, because the shaking of the ship is not convenient for construction, if it is hoisted to the shore for construction, it will be hoisted back to the ship for installation after the assembly is completed, which is very troublesome
