Description
Technical field
The utility model belongs to wind power generation stepped field of structural design, is specifically related to a kind of with transferring the wind power generation stepped of flexible brace by single tension band.
Background technology
Along with increasing of wind-power electricity generation project, the good wind field of some wind-resources has been developed complete, in order to better utilize the wind-resources of higher position, wind power generation steppedly must to develop to high tower aspect.Theoretical research proves, when wind power generation stepped height is more than more than 100 meters, the superiority of framework type pylon highlights, and significantly can save structural cost.But because wind-power electricity generation tower structure exists fatigue problem, comparatively unfavorable for welded construction, so adopt the rigidity brace of high-strength friction bolt connection at present, but this structural meterials utilization rate is low, particularly for pylon hypomere more.For improving the utilization rate of material, selecting prestressing force framework type pylon (king-post employing steel pipe form, brace adopt flexible brace form), greatly can reduce stress amplitude, saving construction cost.But conventional flex drag-line Shi Hanzhang is comparatively loaded down with trivial details, need every root brace to apply respectively, and be difficult to control evenly because of the prestressing force of work high above the ground drag-line, this brings very large difficulty to construction.
Summary of the invention
In order to overcome the above-mentioned defect that prior art field exists, the purpose of this utility model is, there is provided a kind of with can the flexible brace of single tension wind power generation stepped, its with can the flexible brace of single tension band turnover prestressing force as the wind power generation stepped diagonal web member of framework type, replace traditional framework type pylon rigidity brace.
The utility model provide with can the flexible brace of single tension wind power generation stepped, comprise basis, pylon, described basis comprises foundation pier, grade beam, sole plate, described pylon comprises king-post, cross bar, flexible brace, transition segment, described king-post is installed with node pasting board, and suspension column is fixed with suspension column flange; Described flexible brace has 8, be surrounded on the pylon four sides of below framework type high tower transfers to skeleton tower transition segment by steel tube tower, extend to suspension column flange, to cross Nodes at king-post, cross bar and flexible brace, flexible brace walks around king-post, two flexible brace intersections, welding node pasting board on king-post, object positions and prevent the excessive unstability of king-post local pressure to flexible brace, flexible jib head portion, king-post welds drag-line bearing, block end connects crimp and carries out anchoring to drag-line; Flexible brace lower end collects in suspension column and through the pipe laying being welded on suspension column flange, carries out stretch-draw in suspension column flange side to drag-line, connects crimp head anchoring by top board; Pylon more than transition segment still adopts high-strength friction bolt connection rigidity brace; Described node pasting board has groove one and groove two, and groove two, higher than groove one, can avoid the flexible brace of twice mutually to extrude like this.
The utility model provide with can the flexible brace of single tension wind power generation stepped, its beneficial effect is, flexible brace adopts the method from the disposable stretch-draw of pylon upper and lower end, have easy construction, prestress control precisely, save the advantages such as material.

Detailed description of the invention
With reference to the accompanying drawings, in conjunction with an embodiment, to the utility model provide with being described in detail by flexible the wind power generation stepped of brace of single tension.
Embodiment
With reference to Fig. 1-Fig. 9, the present embodiment with can the flexible brace of single tension wind power generation stepped, comprise basis, pylon, described basis comprises foundation pier 6, grade beam 11, sole plate 12, described pylon comprises king-post 1, cross bar 18, flexible brace 2, transition segment 14, described king-post 1 is installed with node pasting board 15, and suspension column is fixed with suspension column flange 5; Described flexible brace 2 has 8, be surrounded on framework type high tower is transferred to the transition segment less than 14 of flexible brace skeleton tower pylon four sides by steel tube tower, extend to suspension column flange 5, to cross Nodes at king-post 1, cross bar 18 and flexible brace 2, flexible brace 2 walks around king-post 1, two flexible brace 2 intersections, welding node pasting board 15 on king-post 1, object positions and prevent the excessive local buckling of king-post 1 local pressure to flexible brace 2, flexible brace 2 upper end, king-post 1 welds drag-line bearing 4, bearing 4 end connects crimp 3 pairs of drag-lines and carries out anchoring; Flexible brace 2 lower end collects in suspension column and through the pipe laying 8 being welded on suspension column flange 5, carries out stretch-draw in suspension column flange 5 side to drag-line, connects crimp head 10 anchoring by top board 9; The pylon of described transition segment more than 14 still adopts high-strength friction bolt connection rigidity brace; Described node pasting board 15 has groove 1 and groove 2 17, and groove 2 17 is higher than groove 1.
The utility model installation process is: first carry out pouring construction to sole plate 12, foundation pier 6, grade beam 11, pipe laying 8, stiffener 7 and top board 9 are welded on suspension column flange 5 side; Then from bottom to up, successively king-post 1, cross bar 18 are installed; To be installed to changeover portion 14, start flexible brace 2 is installed, amount to 8; After whole flexible brace installs, the symmetrical stretch-draw of classification from upper end and suspension column flange 5 place respectively; After stretch-draw, by the crimping anchoring of flexible brace 2 upper end, lower end crimping is fixed on suspension column flange 5 side.The utility model is with transferring flexible brace as the wind power generation stepped diagonal web member of framework type by single tension band, replace traditional framework type pylon rigidity brace, flexible brace adopts the method from the disposable stretch-draw of pylon upper and lower end, have easy construction, prestress control precisely, save the advantages such as material.
