The tie point of steel pipe and top steel column structure；Breach on two waists of steel plate combines to form back taper, as conical steel pipe and separately
The tie point of side conical steel pipe.
Further preferably technical scheme is the utility model, and the upper bottom length of the steel plate is 900 ~ 950mm；The steel
The bottom length of plate is 2500 ~ 3000mm, and radian is 30 ~ 35 °.
Preferably, the difference in height between the peak at upper bottom of the steel plate and the minimum point of arc notch be 150 ~
200mm。
Preferably, the length of the bottom of steel plate is described in the perigee distance of the special-shaped breach on described two waists of steel plate
300~350mm。
Beneficial effect：（1）Conical steel pipe deployed configuration of the present utility model with complex intersection curve can be added by cold pressing
Work shaping method carry out pipe crimping, formed band complex intersection curve pass through prostomum shape tubing string, suitable for major diameter, heavy wall, multi-pipe tubular,
Making with complex intersection curve conical pipe, so as to complete the replacement from steel-casting to welding node, process time is reduced, improves effect
Rate, ensure quality, cost-effective input, environmental protection, solve the problem of different steel weld；
（2）Conical steel pipe deployed configuration of the present utility model with complex intersection curve, have dimensional discrepancy small, precision is high,
The advantages of efficiency high, solve because conical pipe intersection mouth is different in size, steel plate discontinuity during pipe crimping, taper can not be ensured
The problem of pipe shapes.
