Fig. 1 is a schematic diagram of the overall structure of the present invention;

fig. 2 is a schematic view of the structure of the front view direction of the present invention;

fig. 3 is a schematic side view of the structure of the present invention.

In the figure: 1-vertical reinforcing rib plate a, 2-web plate, 3-wing plate, 4-cross support, 5-seat plate, 6-V-shaped plate, 7-connecting vertical plate, 8-vertical reinforcing rib plate b, and 9-oblique reinforcing rib plate.

Detailed Description

Referring to fig. 1-3, the utility model relates to a truss node of area cambered surface has the I-steel truss, and the welding of 3 bottoms of lower pterygoid lamina of I-steel truss has the base, and intermediate position department has a connection riser 7 on the last pterygoid lamina of I-steel truss, should connect the riser with 2 parallel arrangement of web of I-steel truss, intermediate position department has seted up a V-arrangement mouth on the connection riser, and V-arrangement mouthful bottom sets to convex, the laminating is welded and is equipped with a V-arrangement board 6 on the V-arrangement mouth, this V-arrangement board face with I-steel truss length direction is mutually perpendicular and arranges, and the bottom of V-arrangement board is the arcwall face structure.

Further, the base in this embodiment has a cross support 4, and a seat plate 5 is welded to the bottom of the cross support.

Further, in this embodiment, a plurality of vertical reinforcing rib plates a1 are welded at symmetrical positions on the front and rear sides of the web plate of the i-steel truss, and the upper and lower ends of each vertical reinforcing rib plate a are respectively welded to the wing plates of the corresponding i-steel truss.
