2. Description of the Related Art In a box column for a steel frame structure which is made of a thick steel plate and is used in a skyscraper, etc., diaphragms are arranged at predetermined intervals.
After the box is formed, it is placed inside the box in a temporary attachment state.Therefore, the corner of the box at the diaphragm mounting position is punched, and the electrode wire for welding is fed from this hole to weld the end face of the diaphragm to the box. It is fixed. Since such a diaphragm requires a gap for welding between it and the end face portion, a strip-shaped plate is protruded by a predetermined dimension from the flat plate at the peripheral edge portions on both sides of the rectangular flat plate. It is formed so as to have a groove in the end face portion of the flat plate by backing. Since this diaphragm is required to have a large squareness and dimensional accuracy and is required in large quantities, it is formed by using a dedicated jig. Conventionally, the strip plate is placed in a rectangular shape. A jig having a main body frame and a separate frame which is screwed to the main body frame and has a screwed portion formed in an elongated hole so that the dimensions can be freely adjusted is used. Further, this jig had no reversing device and was used by being placed on the floor or the like.

[0003]

However, in this conventional jig, if another frame is bolted while the strip-shaped frame arranged in a rectangular shape is abutted in order to improve the dimensional accuracy of the diaphragm, the welding assembly is performed. Later, there was a problem that the diaphragm could not come off from the frame due to a slight extension or distortion, and it was necessary to hit it with a hammer or loosen the bolt tightened by adjusting the bending angle dimension. In addition, the large diaphragm is heavy and cannot be manually inverted, so it must be inverted using a hoisting machine, etc.
There was a problem that it was very troublesome. The present invention has been made in order to solve such a conventional problem, and the purpose thereof is to make it possible to adjust the size of the mounting portion of the strip-shaped plate so that a diaphragm of an arbitrary size can be obtained. (EN) Provided is a jig for forming a diaphragm of a box column, which can be assembled and can be easily removed after assembling, and can be welded in the same state on both sides by reversing the diaphragm.

[0004]

As means for solving the above-mentioned problems, in the present invention, a diaphragm of a box pillar is arranged by arranging strip-shaped plates in a rectangular shape along the peripheral edges of both sides of a flat plate. A guide for arranging a pair of the strip-shaped plates in a state where corners thereof are orthogonal to each other, which is a jig for forming a base, and the mounting surface is a reference surface portion fixed to a machine frame; A mounting surface disposed at the same level as the mounting surface of the reference surface portion is slidably locked to the machine frame toward a guide on one side of the reference surface portion, and the mounting surface of the one side is attached to the mounting surface. An adjusting surface portion in which a guide is erected parallel to the guide; an advancing / retracting means for sliding the adjusting surface portion to an arbitrary position; an opening provided between the reference surface portion and the adjusting surface portion; one of the reference surface portions The strip-shaped plates laminated on the mounting surface on the side and the mounting surface on the adjustment surface can be freely attached and removed. A fixing means for a constant; and a configuration including: a reversing means for rotating said machine frame in the vertical direction.

To be done. Further, when the strip-shaped plate is placed along the guide on the mounting surface of the adjustment surface portion, the strip-shaped plate arranged in the L shape is arranged in a substantially U-shape, so that the adjustment surface portion is slid by the advancing / retreating means. Adjust to the specified dimensions. On the other side of the open state, a rectangular frame can be formed by placing another strip plate on the placement surfaces of the reference surface portion and the adjustment surface portion. Next, a flat plate formed smaller than the rectangular frame is placed on the rectangular frame so that the peripheral portions are evenly spaced, and then the strip plate is formed on the flat plate in the same rectangular shape as described above. Deploy. And
After fixing the strip-shaped plate and the flat plate in a laminated state by the fixing means, first, the upper strip-shaped plate and the flat plate are fixed by welding. After welding the upper part, the machine frame is rotated in the up-down direction by the reversing means so that the lower surface side faces upward, and the strip plate and the flat plate are welded and fixed from the opening portion to form the diaphragm. After welding, if the adjusting surface portion is loosened by the advancing / retreating means, the two sides of the diaphragm that are orthogonal to each other are opened, and the diaphragm can be easily taken out.
