Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to the structure of a column base, and more specifically to a technique for improving manufacturing and accuracy.

[Background Art] Conventionally, as shown in Fig. 4, the structure of a column base is such that a receiving piece 3 is welded to the upper surface of a cross plate a crossed in a cross shape, and a mounting piece 4 is welded to the lower surface of the cross plate a. It was hot. However, in the structure of the column base having such a configuration, there are problems such as the manufacturing process such as positioning the receiving piece 3 and the mounting piece 4 so that they are approximately parallel to each other is troublesome, and it is also difficult to achieve the precision. .

[Purpose of the invention] The present invention was made in view of these problems, and its purpose is to provide a column base structure that can greatly improve manufacturing efficiency and easily improve its accuracy. It is in.

[Disclosure of the invention] The structure of the column base of the invention is such that an H-shaped steel is cut in its longitudinal direction to a length approximately equivalent to the length of one side of a cross-sectional square, and this cut piece 2
Of the pair of legs of the H-shaped steel, one is used as the receiving piece 3 and the other is used as the mounting piece 4. The column 1 is welded onto the receiving piece 3, and a mounting hole 5 is formed in the mounting piece 4. This is characterized in that a buckling prevention plate 6 is welded between the mounting pieces 4, and by configuring it in this way, the above object is achieved. In other words, the cutting body 2 installed below the column 1 uses a cutting body 2 cut from H-shaped steel, and the receiving piece 3 of one leg piece of the H-shaped steel of the cutting body 2 cut from H-shaped steel is used. By welding the buckling prevention plate 6 between the receiving piece 3 and the mounting piece 4 of the other leg piece, the manufacturability is greatly improved.
is a double-leg piece of H-shaped steel, which is designed to maintain the precision of the steel shape and improve accuracy.

Embodiments of the present invention will be described in detail below based on the drawings.

The width W of the leg of the H-shaped steel is slightly wider than the length w' of one side of the square column 1, and this H
In the longitudinal direction of the shaped steel, the length approximately corresponds to the length w of one side of the rectangular column 1 (the length of one side
Cut it into a length (slightly longer than w' and equal to the width W of the H-shaped steel leg piece). One of the pair of legs of the H-shaped steel of the cut body 2 is made into a receiving piece 3 and the other is made into a mounting piece 4. Each pipe-shaped column 1 is welded onto the receiving piece 3. A mounting hole 5 is formed in the mounting piece 4.
Then, the anti-buckling plate 6 is welded to the web 7 of the H-beam steel between the receiving piece 3 and the mounting piece 4.

In this way, the cutting body 2 installed below the column 1 uses the cutting body 2 cut from H-shaped steel, and the receiving piece 3 of one leg piece of the H-shaped steel and the other By welding the anti-buckling plate 6 between the mounting pieces 4 of the leg pieces, the manufacturability is improved.
The mounting piece 4 and the mounting piece 4 are both leg pieces of H-shaped steel, and if the precision of the steel shape is maintained, the receiving piece 3 and the mounting piece 4 can be kept substantially parallel, and the accuracy can also be improved.

As shown in FIG. 2, a plate 8 is welded directly to the lower surface of the column 1, and the mounting hole 5 of this plate
By inserting and welding the bolts 9 through the beams 10, the column body 1 can be attached to the beams 10 by simply inserting the bolts 9 into the through holes (not shown) in the beams 10 and tightening the nuts from below. The body 1 can be attached to the beam 10.

[Effects of the invention] In short, the present invention is such that an H-shaped steel is cut in its longitudinal direction to a length approximately corresponding to the length of one side of the cross section of a columnar body with a square cross section, and the H-shaped steel of this cut piece is One of the pair of leg pieces of the shaped steel is used as a receiving piece and the other as a mounting piece, a column is welded onto the receiving piece, a mounting hole is formed in the mounting piece, and a buckling prevention plate is installed between the receiving piece and the mounting piece. Since welding is carried out, the cutting body installed below the column is a cut piece of H-shaped steel, and the receiving piece of one leg piece of the H-shaped steel and the other of the cut piece of the H-shaped steel are used. Since the buckling prevention plate is welded between the mounting pieces of the leg pieces, the manufacturing efficiency is greatly improved, and the receiving piece and the mounting piece are
Since it is a double-leg piece of steel molding, it is only necessary to maintain the accuracy of the molding steel, and there is an advantage that accuracy can also be improved.
