Specific implementation mode
Embodiment one
With reference to figure 1 and Fig. 3, so-called T steel component 10 refers in the utility model, by vertical long steel bar 11 and laterally
Short steel bar 12 form, and short steel bar is welded on the middle part of long steel bar, and vertically long steel bar.
T steel component 10 is handled as follows, by 15 degree or so of the upper and lower ends bending of long steel bar, and in the anti-of bending
Side sets up a wedge block 20, which is that up-small and down-big geometry is trapezoidal, by wedge block 20 and long steel bar
Between welded, formed welding point B, welding point B is located at the end of long steel bar, that is, far from the position in the middle part of T shape components, passes through
The pulling force of wedge block dispersed steel component ends.
