さが長くなると次のような不都合を生じる。That is, the anchor bolt fixing length is shown in FIG.
As shown in (1), when an eccentric load acts on the column to generate a bending moment, a compressive force is generated at the foundation rising portion, and a peeling force acts on the fixing plate. As a result, FIG.
A cone-shaped destruction occurs as shown by the broken line in FIG. In this case, the anchoring length of the anchor bolt tends to be longer as the strength of the foundation concrete is lower. When the length of the anchor bolt is long, the following inconvenience occurs.

Since the U-shaped anchor bolt 1 is used for fixing the steel column base according to the present invention as shown in FIG. 8 (a), the steel column base is fixed by the concrete resistance of the bent portion of the reinforcing bar and the adhesive force of the linear portion of the screw reinforcing bar. As the axial force of the U-shaped anchor bolt is increased,
Eventually, the adhesive force goes from the straight part to the bent part,
It is further extended and fixed by a truss mechanism, and is basically different from the fixing method based on the cone breaking strength of concrete by the anchor bolt 5 and the fixing plate 17 shown in FIG. 8B. Therefore, the height of the standing foundation can be low.

られる。FIG. 1 shows an embodiment of a U-shaped anchor bolt fixing structure according to the present invention. The lower part of the U-shaped anchor bolt 1 and the reinforcing bar 2 are buried in the foundation concrete 18, and the two U buried in the foundation concrete 18
The U-shaped bottom of the lower part of the U-shaped anchor bolt 1 is arranged in a cross shape at the bottom, and the base plate 11 of the steel column base is provided on the upper part of the U-shaped anchor plate 1 by the nut 3 and the flat washer 4.
The pillar was established by holding down Here, when the U-shaped anchor bolt is a screw rebar, a nut-type filling fixing plate 13 may be used instead of the nut 3. FIG. 3 (a),
(B) shows an example in which the nut 8 is inserted into the U-shaped anchor bolt 1 in the middle of the U-shaped anchor bolt 1 in the middle thereof to increase the adhesion of concrete. In the case of preventing concrete splitting against the axial force of the anchor bolt in FIG.
The reinforcing ring 12 in FIG. 3A or the reinforcing spiral streaks 16 in FIG. FIG.
The example of arrangement | positioning of the U-shaped anchor bolt 1 of a book is shown. FIG.
(B) shows an example of arrangement of four U-shaped anchor bolts 1. Then, in consideration of the axial force applied to the opposing shaft of the U-shaped anchor bolt, an arrangement can be selected such that the U-shaped anchor bolt 1 can resist the direction in which the force acts. FIGS. 5A and 5B show an example in which a large number of U-shaped anchor bolts 1 are arranged in the case of an H-shaped column or a rectangular column.
FIG. 6 shows details of a steel column base using a threaded reinforcing bar for the U-shaped anchor bolt 1. FIG. 6 shows an example in which a column base plate 11 is fixed with a nut 3 and a reinforcing ring 12 is arranged to prevent splitting of concrete when tension is previously introduced to the U-shaped anchor bolt 1. FIG. 7 shows details of a steel column base using a nut-type filling fixing plate 13.
The base plate of the steel column base is provided with a loose hole 15 through which the upper part of the U-shaped anchor bolt 1 is inserted to install the column at a predetermined position and absorb the manufacturing error of the U-shaped anchor bolt 1. The column base plate 11 is fixed using a nut-type filling type fixing plate 13 after a predetermined tightening.
From 4, a solid agent is injected into the gap between the loose hole 15 and the shaft of the U-shaped anchor bolt 1 to prevent the screws from being loosened, and the steel column base plate 11 is fixed. Confirmation of the filling of the solid agent is based on the fact that the solid agent is ejected onto the upper portion of the nut-type filling fixing plate 13. In the conventional anchor bolt structure as shown in FIG. 2 when introducing the axial force, a predetermined tension is introduced by using the unbonded sleeve 7 to secure the degree of fixation, while the filling type fixing plate 13 is used. In addition, the degree of fixation can be obtained by eliminating the loosening of the screw and fixing by the adhesive force of the reinforcing bar and the U-shaped shape.

ラスメカニズムで定着する。The steel column base anchoring according to the present invention uses a plurality of U-shaped anchor bolts buried in the foundation concrete and arranged so as to intersect the lower U-shaped bottom, so that the bent portion of the reinforcing bar is used. When the axial force of the U-shaped anchor bolt is increased by fixing the concrete resistance and the adhesive force of the linear portion of the screw rebar, the adhesive force eventually passes through the bent portion from the linear portion, and It extends and is fixed by the truss mechanism.

簡素化される。Therefore, the U-shaped anchor bolt anchoring structure of the steel column base of the present invention can be set shorter by the anchoring mechanism as compared with the anchoring length by the conventional anchor bolt, and the fixing degree of the steel column base and the height of the foundation rising portion can be reduced. The design is improved, the height of the standing foundation is low, and the installation of the anchorage is simplified.
