First draw-in groove 4 of lower recess, lower flange 3 is provided with, with the intersection of web 1, the second draw-in groove 5 upwards caved in.
Wherein, this first draw-in groove 4, second draw-in groove 5 extends along the whole longitudinally of main joist 10.
As in figure 2 it is shown, the first draw-in groove 4 and the second draw-in groove 5 are of similar shape and construct.First card
Groove 4 has inlet portion 401 and receiving portion 402, and the sectional dimension of inlet portion 401 is less than receiving portion 402
Sectional dimension.
Preferably, the end of top flange 2 has the first grab 201 downwardly extended, the end of lower flange 3
End has upwardly extending second grab 301.
This main joist 10 has two ends along its longitudinally, and the web 1 of this main joist 10 is dividing
The not part near the two end has some through holes 101.In the present embodiment, through hole 101
With horizontal two rows, vertical three row (2 × 3) arrange (seeing Fig. 1).
Level docking in order to realize any two main joists 10, between 10 ', it is provided that two pieces of planes extend
Clamping plate 20.As it is shown on figure 3, have on clamping plate 20 respectively with two main joists 10,10 '
The installing hole 24 of through hole 101 correspondence on web 1.First, two main joists 10,10 ' are arranged
In alignment, then, two clamping plates 20 is divided near the seam of these two main joists 10,10 '
It is not posted by the both sides of web 1, makes the installing hole 24 on clamping plate 20 and the through hole 101 on web 1
One_to_one corresponding, it then passes through bolt 21, and fix with nut 22, pad 23, see Fig. 4, i.e.
