Embodiment 1

[0037] Such as figure 2 , a direct connection unit side panel 10, the direct connection unit side panel is a unit side panel with a rectangular panel 14, and the side length of the direct connection unit side panel is L1=3000mm.

[0038] The side plate of the direct connection unit is provided with 5 vertical vertical beams 11, the vertical vertical beams are H-shaped steel with a height of 300mm, and horizontal beams 15 are also arranged between the vertical vertical beams, and the horizontal beams adopt 10# I-beam.

[0039] The four sides of the side plates of the direct connection units are provided with unit plate connection sides 12, and the four sides of the side plates of the direct connection units are straight connection sides. The straight connecting sides are welded to the vertical beams and beams to form a frame with high rigidity. The end face of the straight connection side is perpendicular to the panel of the unit side panel.

[0040] The connecting edge of ...

Embodiment 2

[0043] Such as image 3 , a corner connection unit side panel 20, the corner connection unit side panel is a 26-bit rectangular unit side panel, the length of the corner connection unit side panel is L2=4568mm, and the height L3=300mm.

[0044] The side plate of the corner connection unit is provided with 8 vertical vertical beams 21, the vertical vertical beams are H-shaped steel with a height of 300mm, and horizontal beams 28 are also arranged between the vertical vertical beams, and the horizontal beams adopt 10# I-beam.

[0045] The upper and lower sides of the corner connection unit side plate are straight connection edges 22, and one side of the corner connection unit side plate is an oblique connection edge 23, the straight connection edge is welded to the vertical beam, and the oblique connection edge is welded to the crossbeam. The end face of the straight connection side is perpendicular to the panel of the unit side panel. There is an inclination angle α=83.26° be...

Embodiment 3

[0049] Such as Figure 1 to Figure 8 , an assembled steel hanging box, including side walls and a bottom plate. The steel casing has two straight side walls and four inclined side walls, the length of the two straight side walls is L4=12000mm, and the distance between the two straight side walls is L5=9080mm. The two ends of the two straight side walls are respectively connected to a sloped side wall, and the two sloped side walls at each end are connected to each other, and the connection is protruding outward, and the apex angle of the protruding part is γ=166.52°. The height of the assembled steel hanging box is L6=90000mm.

[0050] Each straight side wall is composed of the straight connection unit side panels 10 described in Embodiment 1 of 12. There are 4 straight connection unit side panels arranged in the horizontal direction and 3 straight connection unit side panels in the vertical direction, forming two sides 12m long and 9m long. Tall straight side walls. The un...

Abstract

The invention relates to a split mounting type steel suspension box. The split mounting type steel suspension box comprises a sidewall and a bottom board which are provided with structure beams and surface plates, wherein the sidewall comprises a plurality of unit side plates which are provided with the structure beams, and the surface plates of the unit side plates are rectangular; unit plate connecting sides are arranged at four sides of the unit side plates; the adjacent unit side plates are interconnected through the unit plate connecting sides to form the sidewall; a bottom board connecting side is arranged around the bottom board; the unit plate connecting sides of the unit side plates are connected with the bottom board connecting side of the bottom board. The split mounting type steel suspension box has the beneficial effects that standard profiles being high in structure intensity, flat in processing surfaces, regular in connection and high in matching accuracy are used as the connecting sides of the sidewall and the bottom board, so that the water stopping effect of the steel suspension box can be obviously improved; in addition, the split mounting type steel suspension box is conveniently processed, and the construction cost can be reduced.

Description

technical field [0001] The invention belongs to the field of underwater construction of bridges, and relates to a steel cofferdam device for construction of a water engineering structure, in particular to an assembled steel hanging box. Background technique [0002] Steel hanging box cofferdam is currently widely used in the construction of high pile caps in deep water. Its structure is mainly composed of four parts: side plate, bottom plate, inner support and suspension system. After the deep-water pile foundation is completed, the steel hanging box is installed and lowered with hoisting equipment, so that the entire steel hanging box (and the back-sealing concrete) is suspended on the top of the steel casing of the pile foundation, and then the underwater concrete back-sealing is poured, and the back-sealing concrete forms strength. Finally, the steel hanging box is combined with the back-sealing concrete, and is anchored on the steel casing of the pile foundation through ...
