The width of the gap is not less than the thickness of the steel plate of the H-shaped steel 1 of the cross column.
The radian of the arc-shaped slide way 8 is 90 degrees, the hinged position between the support frame 5 and the baffle 4 is located at the circle center of the arc-shaped slide way 8, the rotation range of the support frame 5 along the arc-shaped slide way 8 is 0-90 degrees, and two limit positions of the support frame 5 in rotation are in a vertical state and a horizontal state.
The support frame 5 comprises a rotating rod 51 and two support rods 52, the two support rods 52 are parallel to each other and are fixed at the upper end of the rotating rod 51, the heights of the two support rods 52 are equal, and when the support frame 5 rotates to the horizontal plane, the upper end surfaces of the two support rods 52 are on the same horizontal plane.
One support rod 52 is positioned at one end of the rotating rod 51 far away from the baffle 4, the other support rod 52 is positioned in the middle of the rotating rod 51, and the support frame 5 forms an F-shaped structure.
And a fixed pin shaft 7 is arranged on the rotating rod 51, and the fixed pin shaft 7 slides in the arc-shaped slide way 8 to drive the support frame 5 to rotate. The cross column can freely pass in and out of the jig frame without being blocked.
An assembling method for assembling a cross column by using the special jig comprises the following steps:
step A, placing the jig frames on a horizontal ground for leveling, wherein a plurality of jig frames are needed, and the positioning among the jig frames is needed to be adjusted, so that the ground beams of the jig frames are kept horizontal and coplanar, and the baffles are ensured to be collinear; rechecking by using measuring equipment after the adjustment is finished, fixing the jig frame to the ground in a mode of ground anchor bolt or welding after the error is confirmed, ensuring that the jig frame cannot move during the assembly, and rechecking again after the fixing to ensure that the jig frame is accurately positioned;
step B, after the jig frame is arranged, rotating the support frame 5 outwards, slowly placing the H-shaped steel 1 of the cross column into the special jig frame from top to bottom, and then performing size rechecking on the H-shaped steel 1;
