By above-mentioned technical proposal, it is to be connected by the mutual drawknot of end plate between newel of the present utility model and Vierendeel girder, the external part of the upper and lower sides of end plate of the present utility model bends inwards 90 degree and forms reinforcing plate, reinforcing plate is used to be connected with the flange plate tension of I-shaped newel, completes being reliably connected between the flange plate of newel and end plate；Two pieces of clamping plates are additionally provided with the plate face of the utility model end plate, the end face of clamping plate extends to form wing plate to both sides, wing plate is parallel with plane where web, be folded in the web of newel between wing plate by the wing plate of the left and right sides, complete being reliably connected between the web of newel and end plate, after the connection of completion end plate and newel, then will be connected with each other by the high-strength bolt in end plate keyhole between newel and Vierendeel girder, you can complete the connection between newel and Vierendeel girder.In order to strengthen connection effect, high-strength bolt used herein is M20 high-strength bolts.
Further, the extension elongation of end plate upper and lower ends described in the utility model is not less than 1/2nd of vertical range between two flange plates.
Further, clamping plate described in the utility model structure in a rectangular trapezoid, two clamping plates are welded in the plate face of end plate by the right-angle side of right-angled trapezium respectively.
Further, the thickness of end plate described in the utility model is 5 ~ 10mm.
The beneficial effects of the utility model are：1. it is to be connected by the mutual drawknot of end plate between newel of the present utility model and Vierendeel girder, the external part of the upper and lower sides of end plate of the present utility model bends inwards 90 degree and forms reinforcing plate, completes being reliably connected between the flange plate of newel and end plate；The two pieces of clamping plates set in the plate face of the utility model end plate, complete being reliably connected between the web of newel and end plate, the design feature that end plate of the present utility model has adapted to I-shaped newel is firmly combined with newel, enhances the reliability connected between newel and Vierendeel girder.2. clamping plate of the present utility model mechanism in a rectangular trapezoid, right-angled trapezium is front wide and rear narrow, can both ensure being located by connecting at bayonet socket, and the weight of backing plate can be mitigated again, facilitates connection to use.
