The utility model relates to a herringbone support steel frame. The method is suitable for the technical field of building structure engineering. According to the technical scheme, the steel frame comprises a steel frame body which comprises a steel beam, steel columns and steel supports, the steel columns are perpendicularly connected to the two ends of the steel beam, and the steel supports which are symmetrically arranged are obliquely connected between the middle bottom of the steel beam and the bottoms of the inner sides of the steel columns; a first joint close to the symmetric center line of the steel beam and a second joint far away from the symmetric center line of the steel beam are respectively formed between the two sides of the steel support and the bottom of the steel beam through the steel support flange plates; the inclined stiffening plate structures are arranged in the middle of the steel beam in an inclined mode, the arrangement positions of the inclined stiffening plate structures correspond to the first connecting positions, the inclined stiffening plate structures are symmetrically arranged about the symmetrical center line of the steel beam, and the included angle opening direction of the inclined stiffening plate structures is consistent with the included angle opening direction of the steel support; and the vertical stiffening plate structures are arranged in the middle of the steel beam and are vertically arranged, the arrangement positions correspond to the second connecting positions, and the vertical stiffening plate structures are symmetrically arranged about the symmetric center line of the steel beam.

This invention relates to a die design method for controlling the strain and filling of high-lumen forgings, belonging to the field of forging die design technology. The method includes: using full-process numerical simulation technology to simulate and analyze the forging process, determining the height and diameter of the blank (L1 and h1); designing the lower die and its cavity based on the forging contour (h2); designing the upper die and its deep cavity based on the high-lumen forging (H, α, R, and L2 < L1); obtaining the upper die's downward pressure t during forging, where t = h1 - h2; comparing the relationship between H and 0.68t to obtain the comparison result; and determining the values ​​of α and R based on the comparison result. This method controls the strain of the high-lumen forging during forging by adjusting the height of the blank, ensuring complete filling of the deep cavity.
