Problems solved by technology
When the corrugated web is not disconnected at the corbel position and the stiffeners are designed like flat web columns, the corrugated web is not enough to withstand the complex forces in the corbel joint domain, resulting in a decrease in the bearing capacity of the joint or even failure
If the corrugated web is disconnected at the corbel position, and the flat web is used instead of the corrugated web to bear the shear force in the corbel joint domain, it will make the component processing very difficult, greatly prolonging the component processing cycle and production cost

Embodiment Construction
[0017] Attached below Figure 1~4 , to describe the implementation of the present invention in detail.
[0018] 1——Wave web column member;
[0019] 2 - corbel;
[0020] 3—horizontal stiffener;
[0021] 4——Vertical cover plate;
[0022] 5—the vertical stiffener of the corbel;
[0023] 6——flange plate of corrugated web column member;
[0024] 7——wave web of column member with wave web;
[0025] 8 - corbel flange plate;
[0026] 9 - corbel web;
[0027] Such as figure 2 , 3 , 4, the corrugated web column member 1 is composed of two flat flange plates 6 and one corrugated web 7 through high-frequency continuous welding, and the members are arranged throughout the length without truncation treatment;
[0028] Such as figure 1 , 2 As shown, the corbel 2 is an I-shaped beam with variable or equal cross-section, which is welded by three flat steel plates 8 and 9, and a vertical stiffener 5 is set at the position of the crane beam; the corbel 2 is welded to the column flan...

The invention relates to a wave web plate door-type rigid-frame bracket connecting node, consisting of a wave web plate column member, a bracket, horizontal reinforced ribs and vertical cover plates, wherein the wave web plate column member is formed by high-frequency continuous welding of two flat-wing edge plates and one wave web plate; and the member is arranged in the full-length manner without cutting-off treatment. The four horizontal reinforced ribs are arranged in the wave web plate column member and are arranged levelly to the upper wing edge and the lower wing edge of the bracket, and the peripheries of the four horizontal reinforced ribs are connected with the column wing edges and the web plate in a welding manner; and the length of each horizontal reinforced rib is the same as the height of the wave web plate, the width of each horizontal reinforced rib is blanked according to the actual size of the wave amplitude, and the outer side of each horizontal reinforced rib is level to the outer side of a column wing edge plate. The two vertical cover plates are same in size, are arranged at the area enclosed by the horizontal reinforced ribs and the wave web plate column member, and are tightly attached with the wave web plate; the peripheries of the cover plates are connected with the horizontal reinforced ribs in a welding manner, and the angle parts of the cover plate are not welded or angle-cut. In the novel bracket connecting node, the vertical cover plates are added in the range of steel columns of the bracket, so that not only is the manufacturing process simpler, but also the bearing force of the node is also greatly improved.
Description
technical field [0001] The invention relates to a novel wave web portal type rigid frame corbel connection node, which belongs to the technical field of structural engineering. Background technique [0002] Wave web I-shaped member is a new type of high-efficiency profile, which originated in Europe and has been widely used in steel structures of portal frame light buildings in Germany, Austria, the United States, Sweden, Australia and other countries in recent years. This type of member is composed of a corrugated web and a flat flange through high-frequency continuous welding. According to the corrugation form of the web and the shape of the flange section, it can be divided into various forms: the web is divided into sinusoidal wave web, trapezoidal wave web, triangular wave web, etc., and the flange is divided into flat flange and box wing Edge and so on. The wavy web I-shaped member is an I-shaped member with a flat flange and a sinusoidal web. [0003] Corrugated we...
