Description

Special node model processing method based on component end processing Technical Field The invention relates to the technical field of component end TOUCH, in particular to a special node model processing method based on component end processing. Background In the background of the current production design using AM12 and the like as production design software, the structural aspect production design almost completely depends on structural design drawings for operation, in the structural design drawings, angle steel TOUCH in two directions is a very common structural form, in the conventional arrangement, angle steel panels are arranged in the same direction, but in the structural form, there is a relatively special case that the two angle steel TOUCH are arranged, but the angle steel panels face different sides, such as the end parts of the conventional reference angle steel are kept as the same, and a section of flash is formed at the angle steel panel positioned at the lower part (as shown in figure 1); with the current treatment method, stress points are easy to generate at the positions, which is not beneficial to the structural strength, and the field fillet welding at the flash is difficult and is not attractive. Disclosure of Invention The invention aims to provide a special node model processing method based on component end processing, which optimizes a component end TOUCH form to improve structural strength and improve operation efficiency by designing a processing scheme. The technical aim of the invention is realized by the following technical scheme: a special node model processing method based on component end processing is applied to a first angle steel and a second angle steel to be welded with each other, and comprises the following steps: the end parts of the first angle steel and the second angle steel are treated, and the treated end parts of the second angle steel are welded to the first angle steel and are welded between the first angle steel and the second angle steel through toggle plates; The processing of the end part of the second angle steel comprises the steps of cutting off a panel of the second angle steel, reserving roots at the position, where the panel is close to the web plate, cutting off a preset length of the panel along the length direction of the second angle steel, obliquely cutting off the panel in the outer direction, and then forming a unilateral groove on the web plate of the second angle steel, wherein the groove direction is on the abdomen side. Still further, leave t+r in the second angle steel root portion, t is the web plate thickness of first angle steel, and r is the circular arc radius of first angle steel web side board and web junction. Further, the preset length of the second angle steel cut off at the root-leaving position is 25mm. Still further, the second angle is beveled at an angle of 30 °. Further, the processing of the end part of the first angle steel comprises the steps of leaving roots on the panel of the first angle steel close to the web plate, and making oblique inclinations on the positions where the roots are left in the outer side direction. Still further, the first angle steel leaves a root place for 30mm. Still further, the first angle steel is beveled at an angle of 30 °. Furthermore, the toggle plate is subjected to the following treatment in advance, the hole is additionally formed in the corner end of the toggle plate, the grooves on two sides of the toggle plate are formed, and the grooves on two sides of the toggle plate are arranged in opposite directions. Further, the toggle plate opening is an arc-shaped hole with the radius of 60 mm. In summary, the invention has the following beneficial effects: According to the existing reference end treatment method, the angle steel panel positioned at the lower part flies out of the web plate of the angle steel above (the first angle steel), and the angle welding treatment is carried out on the flying place of the panel, so that the scheme with flash has more defects, is not only easy to generate stress points, but also inconvenient for field treatment and has influence on the field welding efficiency; When the production design modeling is carried out, the end part form is modified, the second angle steel panel is partially cut off to cancel flash, the angle steel is subjected to groove processing, the original angle welding form is changed into groove welding, and the web plates of the two angle steel are aligned, so that the surface of the toggle plate clamped between the two angle steel panels is flush with the web plates, and the subsequent welding work is convenient after the shape and groove processing are carried out on the toggle plate.
