DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apparatus for welding and joining a column with a diaphragm and an H-section steel in assembling a steel frame of a structure.

[Conventional technology]

As is well known, in steel frame assembly, a column with a diaphragm and an H-beam are welded and joined together, but conventionally, although not particularly shown, the column is erected on a surface plate and the inner surface of the diaphragm of the column is welded. If they do not match, insert a steel plate, etc. between the lower flange of the H-beam and the surface plate to fill the gap and make them match, and then apply the insert. It is common to check the right angle of the H-shaped steel before welding.

[Problem that the invention seeks to solve]

However, such joining, which is carried out entirely by hand, not only requires a considerable amount of skill and skill, but also has the problem that it is time consuming and has poor workability.

The present invention was made in view of such conventional problems, and its purpose is to simplify and accurately join a column with a diaphragm and an H-shaped steel in a short time. Column with diaphragm and H for excellent workability
The purpose of the present invention is to provide a device for attaching to shaped steel.

[Means for solving problems]

For this purpose, the present invention includes an upright holding mechanism 10 that is removably and fixedly placed at a predetermined position on a base 16 and that holds the diaphragm-equipped column 100 upright in a vertical position; It is raised and lowered via a lifting mechanism 22 provided on the base 16, and the standing holding mechanism 10

The present invention is characterized by a configuration including an H-beam holding mechanism 42 that holds the H-beam 200 joined to the H-beam 104 horizontally and vertically and raises and lowers it.

[For production]

The operation of this device will be explained.

First, the upright holding mechanism 10 is fixed at a predetermined position on the base 16 by attracting its magnet stand 11, and as shown in FIG. A portion of the column 101 is placed and attracted through the excitation of the magnet body 14, and then the arm 13 is raised from A' to A by a means such as manually or by a crane, and the arm 13 is locked to the lock pin 15. Stand up vertically until the The column 100 is then held in a vertical position, as shown in phantom lines in FIG. Next, as shown in FIG. 2, the threaded rod 21 moves upward in the mouth direction through the operation of the lifting mechanism 22 in the vertical holding mechanism 18, and the magnet body 24 is energized to move the column 100.
It is attracted to the center portion of the lower surface of the lower diaphragm 104, and by turning on the free lock mechanism 23, the threaded rod 21 and the like are fixed vertically, and the column 100 is held horizontally and vertically.

Once the column 100 is held vertically, the magnet body 14 is demagnetized to release its adhesion and the arm 13 is tilted in the A'' direction so that it does not interfere with the next work.

Then, if the total length of the column 100 is, for example, 400 m and the thickness of the diaphragm 103, 104 is 13 nn,
By moving the upper light beam 33 up and down, the distance L' (see FIG. 4) between the center of the upper light beam 33 and the center of the lower light beam 31 in the beam measuring mechanism 25 is determined by the scale 36 of the upper and lower diaphragms 103. The distance L between ゜104 (see Figure 2) is 374
m, the intersection of the upper light beam 33 and the scale 36 is locked with a thumbscrew 36' to maintain the distance L', and fixed to the support 28 with the holding attachment part 34 and the fixing device 35. Then, beams are emitted from the upper light beam 33 to the lower surface 103a of the upper diaphragm 103 and from the lower light beam 31 to the upper surface 104a of the lower diaphragm 104 (see FIG. 1), so that the column 100 is actually set. Check whether it matches the dimensions and set the set dimensions (37
4m), in order to average the error, the average spacing of the columns 100 is determined by the vertical holding mechanism 1.
The height of the column 100 is adjusted by moving the column 100 up and down by the operation of the lifting mechanism 22 at step 8.

At this time, the numerical value on the scale 29 located on the central axis of the upper light beam 33 in the beam measuring mechanism 25 is joined to the column 100.
1 to the lower surface 201a.

Next, after placing the H-shaped lower flange 202 on the left and right hook rods 46 of the holding mechanism 42, the hook rods 46 are moved in two directions (the fifth direction) through the operation of the drive mechanism 51.
(see figure) to bring the end faces of the upper and lower flanges 201 and 202 into contact with the end faces of the support column 43 to hold the H-beam 200 horizontally and vertically, and then the drive mechanism 51 and threaded rod 52 operate. The hook rod 46 is moved upward in the E direction through the
01a to the position of the scale 45 having the same numerical value as the scale 29 in the beam measuring mechanism 25, and then move the movable plate 4
0 by manual or mechanical means in the direction from to to' as shown by the solid line in FIG. Move the H-shaped steel 2 in the direction of the harbor shown by the solid line in the figure.
00 center to the diaphragm 103 of column 100.
Set the position relative to the plane reference point (center line) a of 104,
Next, the column 100 and the H-section steel 200 are welded at the diaphragm 103, 104 and flanges 201 and 202, etc., to join them together.

After the H-shaped m200 is welded and joined to the column 100 in this manner, each mechanical part is operated in the opposite manner to the above, and the joined article is removed from the base 16.

Note that the column 100 and the H-shaped m200 are connected to the upper surface of the upper diaphragm 103 of the column 100 and the H-shaped m200.
Of course, the upper surface of the upper flange 201 may be joined together in some cases.

In addition, in order to join the H-beam 200 to the column 100 at a so-called water angle or Kinoshita angle, the scale 45 of the support 43 in either one of the H-beam holding mechanisms 42 is shifted to set the position of the H-beam 200. do it.
