In this embodiment, connecting portion 51 is the rectangular plate of vertical setting, spacing portion 52 is right angle trapezoidal plate and right angle triangle shaped plate, and its hypotenuse is spacing face of limit baffle 5 to beam column node 4, can lead to and spacing the decline of beam column node 4, is favorable to the butt joint of beam column node 4 and steel-pipe column 3. Besides, a certain clearance, such as 1-2mm, exists between the inclined surface 521 and the surface of the steel pipe column 3, which is a reserved horizontal position adjustment amount.

As shown in fig. 6-7, when the alignment of the beam-column node 4 and the steel pipe column 3 is completed, a gap at the butt joint between the steel pipe column 3 and the beam-column node 4 needs to be filled with a backing plate 6, the backing plate 6 is disposed between the steel pipe column 3 and the beam-column node 4, and the backing plate 6 is not shown completely. The backing plate 6 generally adopts the steel backing plate 6, can pack the clearance closely knit, the welding after being convenient for beam column node 4 and 3 counterpoints of steel-pipe column.

The embodiment also provides a construction method for connecting the beam column node 4 to the steel pipe column 3 in an aligned manner by adopting the butt joint structure of the beam column node and the steel pipe column, which comprises the following steps:

the method comprises the following steps: manufacturing a regulating device: the finish rolling deformed steel bar and the steel support bracket 21 are combined to manufacture the standard part of the connecting part 2, the length of the finish rolling deformed steel bar is not too long, the rigidity of the finish rolling deformed steel bar is ensured, and the two connecting parts 2 are connected and adjusted through the positive and negative wire sleeves 1;

step two: and (3) mounting a connecting part 2 on the steel pipe column 3 below the beam column node 4: lofting out the axis of four joints 42 of beam column node 4 at steel-pipe column 3 to the planar position at its installation place according to adapting unit 2's length lofting, with adapting unit 2 welding position firm, along four limit baffle 5 of steel-pipe column 3 radial welding simultaneously, the upper portion beam column node 4 of being convenient for is counterpointed fast. The center-to-center distances between the positioning rods 22 of all the connecting members 2 and the steel pipe column 3 should be kept the same.

Step three: as shown in fig. 4, the connecting member 2 is mounted on the beam-column node 4: in a similar way of installing the connecting component 2 on the steel pipe column 3, the position of the axis of the joint 42 and the installation plane of the connecting component 2 is set out on the column head 41 of the beam column node 4. A1 cm gap is reserved between the finish rolling screw-thread steels of the upper connecting part 2 and the lower connecting part 2, and the center distances between all the connecting parts 2 and the steel pipe column 3 are consistent and are the same as the center distances between the connecting parts 2 on the steel pipe column 3 and the steel pipe column 3.

Step four: as shown in fig. 5, the positive and negative wire sleeves 1 are installed: screwing the positive and negative screw sleeves 1 into 1-2 screws in the finish-rolled deformed steel bars of the connecting parts 2 of the steel pipe column 3, wherein the screwing amount of each positive and negative screw sleeve 1 is the same, and the top surfaces of the positive and negative screw sleeves 1 are positioned on the same horizontal plane.

Step five: as shown in fig. 6, the beam-column joint 4 is initially aligned: hoist beam column node 4 to steel-pipe column 3 top, must ensure beam column node 4 hoist and mount level during hoist and mount, make things convenient for the later stage to counterpoint. After the horizontal direction rotation of beam column node 4 is taken one's place, beam column node 4 is transferred along limit baffle 5, and after the finish rolling screw-thread steel on beam column node 4 and just turning round the silk sleeve 1 and tentatively counterpointing, continue to transfer beam column node 4, make finish rolling screw-thread steel seat on just turning round the silk sleeve 1.

Step six: as shown in fig. 7, the beam-column joint 4 is finely adjusted in position: and adjusting and connecting the finish-rolled deformed steel bar of the beam column joint 4 and the finish-rolled deformed steel bar of the steel pipe column 3 in place through forward or reverse rotation of the forward and reverse screw sleeves 1, wherein the forward and reverse screw sleeves 1 are screwed in synchronously in the adjusting process. And after the positive and negative screw sleeve 1 is screwed to the beam column node 4 and the steel pipe column 3 and the width of a welding seam is reserved, measuring and rechecking the elevation of each joint 42, judging the positive and negative screw rotation amount in the direction of each joint 42 according to the measurement result, and finely adjusting in place by rotating the positive and negative screw sleeve 1 in sequence. And after fine adjustment and error-free rechecking, a steel base plate 6 is adopted to fill and compact the gap between the column joint and the steel pipe column 3.

Adopt this embodiment the butt joint structure of beam column node and steel-pipe column realizes beam column node 4 and docks steel-pipe column 3 fast, and its simple operation, high efficiency have solved that traditional butt joint time is long, the butt joint degree of difficulty is big and the butt joint interface matches the difficult problem that the straightness that hangs down of steel-pipe column 3 and beam column node 4 is difficult to guarantee, high efficiency just ensures installation progress and precision. Aiming at the beam column node 4 of the cross orthogonal beam, the traditional process method is adopted to accurately align the plane positions and elevations of the four joints 42 of the cross orthogonal beam, the construction process is complicated, the work efficiency is low, the installation precision is difficult to guarantee, meanwhile, the adjustment process is easy to cause the overturning of the beam section, and the safety risk is extremely high. In this case, the butt joint structure of the beam column node and the steel pipe column is provided, and the adjusting devices are welded and installed on the steel pipe column 3 and the beam column node 4 to be installed, and are rotationally connected in place through the positive and negative wire sleeves 1 after on-site alignment. The method is simple and efficient to operate, can avoid the overturning safety risk of the beam-column node 4, and is safe, efficient, and controllable in progress and precision.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
