The specific embodiment
Below in conjunction with accompanying drawing 1 to accompanying drawing 3 and the specific embodiment, the present invention is described in further detail:
Embodiment 1
Freely-supported turns continuous interconnection box-beam structure, as shown in Figure 1, 2, comprises one group of above case beam 1, and an end of the main steel strand cable 13 in described case beam 1 is connected with the adjacent tank beam.The anchorage point of main steel strand cable is moved in adjacent beam-ends, because the interior space of case beam is larger, enough staff enter, and therefore can carry out secondary to the steel strand cable tightens up or change rope.
The adjacent tank beam comprises right adjacent case beam 3, in right adjacent case beam 3, is right hollow space 31, is provided with a right anchorage point 32 in right hollow space 31, and main steel strand cable 13 right-hand members are connected with a right anchorage point 32.The left end of main steel strand cable 13 is connected with the main anchorage point 14 that is arranged on case beam 1 outside.Main steel strand cable 13 is crossed over two adjacent case beams, improves two bonding strengths between the adjacent tank beam, simultaneously, has and changes the advantages such as convenient.
Case beam 1 left side arranges left adjacent case beam 2, and the right-hand member of the left main steel strand cable 23 in left adjacent case beam 2 is connected with the first anchorage point 15 in being arranged on case beam 1, and the right-hand member of the right main steel strand cable 33 in right adjacent case beam 3 is connected with the anchorage point of right adjacent case beam 3 outsides.
Also be provided with horizontal steel strand cable 4 between case beam 1 and adjacent tank beam, case beam 1 is connected by tensioning with the lower end of adjacent tank beam.Make to occur directly to hold out against between case beam and case beam.By arranging horizontal steel strand cable 5, improved the stability connected between the adjacent tank beam.
Case beam 1 is prestress steel concrete case beam.Also be provided with the steering gear of steel strand cable in case beam 1, main steel strand cable 13 is through the steering gear of steel strand cable.Prestress steel concrete case beam is corrugated sheet steel case beam, in the trough of the Wavelike steel webplate in corrugated sheet steel case beam, is welded with stiffener, and the steering gear of steel strand cable is arranged on stiffener.
Because in existing case beam, the quantity of cross wall is limited, therefore spacing is also fixed, so often less as the fixed point quantity of steering gear with cross wall, make the arc line type of steel hinge rope become broken line type, utilize in the trough of Wavelike steel webplate and be welded stiffener, according to the line style of steel hinge rope, a plurality of steering gears are installed on stiffener, make the line style smoothness of steel hinge rope, meet load requirement.Be welded with stiffener in corrugated sheet steel case beam in the trough of Wavelike steel webplate, the steering gear of steel strand cable is arranged on stiffener.Utilize the fixed point of the stiffener of Wavelike steel webplate as steering gear, can make a plurality of steering gears makes the line style of steel hinge rope reach optimum state, in using, when the case beam produces downwarp, regulate density degree and the position of steering gear, when carrying out two times tensioning, can control and alleviate the situation of case beam downwarp, make steel hinge bands type reach optimum state, maintenance cost is low.
It is good that this freely-supported turns continuous operability, easy construction, and maintenance cost is low, good economy performance.
Freely-supported turns continuous interconnection box-beam structure, as shown in Figure 1, 2, comprises one group of above case beam 1, and an end of the main steel strand cable 13 in described case beam 1 is connected with the adjacent tank beam.
In the adjacent tank beam, anchorage point is set, main steel strand cable 13 is connected with the anchorage point arranged in the adjacent tank beam.Therefore, change or only need in the adjacent tank beam, can carry out corresponding operating during tensioning steel strand cable.
The adjacent tank beam comprises right adjacent case beam 3, in right adjacent case beam 3, is right hollow space 31, is provided with a right anchorage point 32 in right hollow space 31, and main steel strand cable 13 right-hand members are connected with a right anchorage point 32.
The adjacent tank beam also comprises left adjacent case beam 2, in left adjacent case beam 2, is left hollow space 21, is provided with right two anchorage points 22 in left hollow space 21, and the left end of main steel strand cable 13 is connected with right two anchorage points 22.Main steel strand cable 13 is crossed over three case beams, improves three bonding strengths between the case beam, when replacing or tensioning, only needs left adjacent case beam 2 can complete corresponding work with right adjacent case beam 3 is interior, has tensioning conveniently, changes the advantages such as quick.
Left main steel strand cable 23 in left adjacent case beam 2 is connected with the first from left anchorage point 15 of case beam 1 interior setting, and the right main steel strand cable 33 in right adjacent case beam 3 is connected with the right side one anchorage point 12 of case beam 1 interior setting.
Also be provided with horizontal steel strand cable 4 between case beam 1 and adjacent tank beam, case beam 1 is connected by tensioning with the lower end of adjacent tank beam.
Case beam 1 is prestress steel concrete case beam.Also be provided with the steering gear of steel strand cable in case beam 1, main steel strand cable 13 is through the steering gear of steel strand cable.Prestress steel concrete case beam is corrugated sheet steel case beam, in the trough of the Wavelike steel webplate in corrugated sheet steel case beam, is welded with stiffener, and the steering gear of steel strand cable is arranged on stiffener.
In a word, the foregoing is only preferred embodiment of the present invention, all equalizations of doing according to the present patent application the scope of the claims change and modify, and all should belong to the covering scope of patent of the present invention.
