Tweendeck support and connection structure in a kind of wind generator tower tube and jacket basis has a vertical column in the middle of the tweendeck supporting structure, this column is connecting duct frame basis and the main member of blower fan tower barrel; Column top, bottom are provided with the deck that contains stiffening rib, and column is welded on two decks, and two decks produce horizontal shear force and moment of flexure during fan operation in order to opposing, cause the distortion of tower tube or column when preventing fan operation; Between two decks, also be provided with the vertical panel that contains stiffening rib, vertical panel has increased stressed area of contact between two decks, reduces stress and concentrates; The moment of torsion and the horizontal force that produce when vertical panel can also bear fan operation simultaneously produce the opposing moment of flexure.
Further improve: be provided with a plurality of vertical tubes between two decks, two decks all are welded on the vertical tube, and a plurality of vertical panels weld with column, vertical tube respectively round column and vertical panel two ends.
Further improve: vertical tube can be vertical tube or vertical square tube.
Further improve: two decks are that quadrilateral is dull and stereotyped, and four vertical tubes are positioned at two decks, four corner locations, and said vertical panel has four, and four vertical panels are arranged along the quadrilateral diagonal.
Further improve: bulkhead is to form the platform of a circumferential sealing outside around two decks, can also being provided with.
Further improve: said vertical panel upper and lower end respectively with the welding of two decks, be welded with on the said vertical panel level to and/or vertically to stiffening rib.
Further improve: column is a steel cylindrical tube.
Further improve, the jacket basis is welded by three above root steel legs and some reinforcement connecting rods, and each steel leg upper end extends to deck, column bottom with the taper of drawing close to the center, and some reinforcement connecting rods are separately positioned on and face mutually between two steel legs.
Further improve, strengthen connecting rod diagonal brace or stull or arranged in a crossed manner between the steel leg.
The present invention with respect to the beneficial effect of existing technology is:
1, center pillar of the present invention top, bottom all are furnished with the deck, and column is welded on two decks, and the deck produces horizontal shear force and moment of flexure during in order to the opposing fan operation, causes the distortion of tower tube or column when preventing fan operation; Four vertical panels weld with column, vertical tube respectively round column and vertical panel two ends simultaneously, and four vertical panels are arranged along the quadrilateral diagonal, have increased the stressed area of contact between column and deck, the jacket; Reducing stress concentrates; Vertical panel makes and produces the opposing moment of flexure, with respect to existing technology by moment of torsion and the horizontal force that the present invention produces in the time of can bearing fan operation; The structure that deck, vertical panel link to each other with column respectively can reduce the stress of blower fan tower barrel and jacket joint and concentrate; The column wall thickness reduces, and steel using amount reduces, and loading transfer rationally, simply; And vertical panel can effectively increase the usage space on the tweendeck supporting structure, has in the tweendeck supporting structure to can be used for placing Fan Equipment, maintenance tool and live the people space.
2, there are three above steel pipe legs on the jacket basis, between two steel legs, is equipped with the reinforcement connecting rod, strengthens diagonal brace or stull or arranged in a crossed manner between the connecting rod steel leg, in order to strengthen the rigidity and the stability of jacket.
