という問題がある。However, as the size of the structure increases, it is necessary to increase the thickness of the anchor beam 26. In addition, the anchor beam 26 must be made of a high quality material and the welding amount of the anchor beam 26 must be increased. The increase is inevitable, and the anchor beam 26 itself becomes large, which causes problems in cost, transportation, and erection. On the other hand, in addition to the anchor frame method, as shown in FIGS. 13 and 14,
Deformed steel bar 30 with headed stud 29 fixed by welding
There is also a system in which the anchor frame is used as an anchor bolt, and it is fixed directly to the concrete footing mainly by the adhesive force of the deformed steel bar 30 having the headed stud 29. However, in this system, the problems of the anchor frame system are considerably Although it can be advantageously solved, in this case, there is a problem that the fixing length of the deformed steel bar 30 becomes long in order to obtain the necessary fixing force. For example, the concrete footing 2
Due to the reason that the thickness of 4 must be made thicker than necessary, there was a problem that the construction cost was increased. Also, in order to increase the adhesive force of the anchor bolt,
A method of welding the headed studs 29 and the like to the deformed steel bar 30 is also used, but in this case, the number of headed studs 29 to be welded is extremely large, and the labor required for processing is large, resulting in high cost. However, there is a problem that the manufacturing efficiency is low. Furthermore, in the case of the direct fixing method using the bolt 27 to which the unbonding agent 28 is attached as shown in FIG. 12, there is a problem that the attachment strength of the pier 25 to the footing 24 is weak.
