Even when the lock bolt 60 is fastened and fixed, the gate holding member 50 can still be rotated about the lock bolt 60 as an axis.

(Crossgate mounting method)
Next, a method for attaching the cross gate will be described.

  First, as shown in FIG. 1, the case of an upward gradient will be described.

  In this case, as shown in FIG. 2, in the upper connector 10, the lock bolt 60 is fastened and fixed at the root portion of the slide groove 37. Further, in the lower connector 10, the locking bolt 60 is attached in a loosened state, and the sliding operation of the locking bolt 60 with respect to the slide groove 37 is made free.

  Here, in the connector 10 according to the present embodiment, when the lock bolt 60 is fastened and fixed at the base portion of the slide groove 37, the stopper 38 provided in the guide block 30 and the notch 53 of the gate holding member 50 are formed. It is formed to engage.

  That is, as shown in FIG. 5, when the lock bolt 60 is fastened and fixed at the base portion of the slide groove 37, the stopper 38 provided on the guide block 30 engages with the notch 53 of the gate holding member 50 to hold the gate. The rotation of the member 50 is suppressed. For this reason, even when a lateral load is applied by opening and closing the cross gate or the like, the rotation of the gate holding member 50 is suppressed and the gate is firmly locked.

  In this embodiment, the lock bolt 60 is fastened and fixed at the most base portion of the slide groove 37, that is, at the position where the gap between the column 1 and the vertical beam 4 of the gate body 2 is the smallest. The lock bolt 60 is fastened and fixed. The stopper 38 engages with the notch 53 when the lock bolt 60 is fastened and fixed at this position. For this reason, the guide block 30 and the gate holding member 50 are firmly locked at the position where the gap between the column 1 and the vertical beam 4 becomes the smallest.

  In this embodiment, the lock bolt 60 is fastened and fixed in a state where the guide block 30 and the gate holding member 50 are aligned in substantially the same direction, in other words, in a state where the longitudinal direction of the slide groove 37 is the vertical direction. At this time, the stopper 38 is configured to engage with the notch 53. Therefore, even when a horizontal force is applied, the sliding movement along the slide groove 37 does not occur without the guide block 30 rotating, so that the stopper 38 engages with the notch 53. Thus, since the rotation of the guide block 30 is suppressed, the structure is strong against a load in the horizontal direction.

  As described above, in the upper connection tool 10, the connection tool 10 is firmly fixed, and the gap between the column 1 and the vertical beam 4 can be kept small. Further, in the lower connector 10, the gate holding member 50 is rotatable and slidable, so that the gate body 2 is stable in a tilted state corresponding to the slope of the slope. For this reason, the load does not concentrate on a part of the crossbar 3 constituting the gate body 2, and an unreasonable load can be applied anywhere corresponding to the inclined installation surface without the crossbar 3 having a special structure. Therefore, it can be installed in a good condition.

  Next, the case of a downward gradient as shown in FIG. 6 will be described.

  In this case, contrary to the upward slope, the lock bolt 60 is fastened and fixed at the root portion of the slide groove 37 in the lower connector 10. Further, in the upper coupling tool 10, the lock bolt 60 is attached in a loosened state, and the sliding operation of the lock bolt 60 with respect to the slide groove 37 is made free. Although not particularly illustrated, at this time, in the lower connector 10, the stopper 38 provided in the guide block 30 is engaged with the notch 53 of the gate holding member 50, and the rotation of the gate holding member 50 is suppressed. It is like that.

  As described above, also in the case of the downward slope, the same effect as that in the case of the upward slope can be obtained only by changing the fixing method of the lock bolt 60 by the upper and lower connectors 10.

(Cross gate transport method)
FIG. 7 is a view for explaining a cross gate transfer method according to the present embodiment.

  As shown in FIG. 7, when the cross gate according to the present embodiment is transported, the connector 10 and the gate body 2 are fixed with the PP band 80 in a folded state. That is, the connector 10 is conveyed in a locked state as shown in FIG. For this reason, the guide block 30 does not protrude to the outside of the gate body 2 and can be made compact even during conveyance.
