The purpose and the effect of the F-shaped welding connecting plate structure are achieved by the following specific technical means:

an F-shaped welding connecting plate structure comprises a framework welding pipe; the outside welding of body of skeleton welded tube is at the plate body top surface of connecting plate.

Furthermore, the middle part of the plate body of the connecting plate is provided with a top welding plate.

Furthermore, the bottom of the connecting plate body is provided with a bottom welding plate, and the bottom welding plate is designed in a circular arc shape.

Further, the cross-sectional shape of the connecting plate is an inverted 'F' shape.

Compared with the prior art, the invention has the following beneficial effects:

the device changes traditional "I" type connecting plate into "F" type connecting plate, and change back connecting plate and skeleton welded tube area of contact increase to welding point rational distribution forms bigger "delta" welding position about the skeleton welded tube, reduces welded tube thermal deformation, and the solder joint is connected more rationally, makes skeleton welded tube welding more sturdy and durable on the connecting plate, has reduced the number of times of quality claim, has improved the device's practicality and stability.
