を受けることが少ない。Since the metal joint 6 attached to the flange 1a and the web 1b of the steel column 1 does not protrude greatly from the steel column 1 in the horizontal direction, it hardly interferes with the column main reinforcing bar 29 as shown in FIG. Further, since the joining plate 8 is narrow, the main reinforcing bar 32 of the foundation beam 31 can be avoided, and there is little restriction on construction.

An embodiment is shown, and the basic structure is the same as that of the first embodiment, except that it is located at a coupling position with the cylindrical body 7 which is the base of the joining plate 8 so that the cylindrical body 7 protrudes. Vertical ribs 34 for reinforcement protrude from both sides of the surface.

In addition, it is hardly deformed, and the strength against bending is increased.

と干渉しにくく、施工上の制約が少なくなる。As described above, in the metal joint for steel column base of the present invention, the joint plate is fixed to the web or flange of the steel column base with bolts, and the anchor bolt is inserted into the cylindrical body part. The steel column can be installed on the concrete base simply by fixing it, and the steel column can be connected to the anchor bolts via metal joints.This eliminates the need for a conventional base plate and reduces the work of welding the steel column to the base plate. The workability is improved, and the installation space on the concrete base is small, so that it hardly interferes with the main reinforcing bars of the columns or the main beams of the foundation beams, and the restrictions on the working are reduced.

Adjustment of the installation position can be easily performed. Furthermore, even if the joining plate is flat, it can oppose the deformation and bending at a coupling point with the cylindrical body part where stress is particularly apt to be applied, and the bending resistance is increased without being easily deformed.

必要がなく簡単である。The method of fixing the steel column base is as follows. The joint plate is fixed to the web or flange of the steel column base with bolts, and the anchor bolt is inserted and fixed to the cylindrical body to fix the steel column to the concrete base. Because it can be installed, it can be easily constructed.
In addition, when the steel column is installed, the vertical position adjustment is performed with a lock nut that tightens and fixes an anchor bolt to the cylindrical body, so that it is not necessary to fill the mortar or the like as in the conventional case, so that it is simple.
