The second gripping portion 21 is composed of a pair of connecting pieces 22, locking pieces 23, and bent pieces 24 that are connected to both sides of the base portion 10 in the same manner as the first gripping portion. The piece is formed so as to be located on the side opposite to the first gripping portion 11.
That is, the second gripping portion 21 is connected to each of the rectangular connecting pieces 22 that are bent and connected at substantially right angles from both sides of the base portion 10 in a direction intersecting the first gripping portion 11, and Each square-shaped locking piece 23 that is bent and connected to each connecting piece 22 and connected to each locking piece 23 by being bent outward and narrower than the locking piece. Each bent piece 23 has a square shape, and each locking portion 25 is formed by bending a triangular portion at the corner of each locking piece 24 inward.
[0015]
With the above configuration, the connecting piece and the locking piece of the first holding part and the second holding part are formed integrally with the base part 10 to have a spring action on the base part 10.
[0016]
Further, convex pieces 26 are formed on both sides of the one connecting piece 22 so as to be on the second gripping portion 21 side. For example, when the spring force in the first gripping portion 11 and the second gripping portion 21 is different, this convex piece is for easily confirming which side is the second gripping portion side. is there.
[0017]
Next, a procedure for fixing the anchor bolt and the muscle body using the cross bolt fixing bracket having the above structure will be described with reference to FIGS.
In the part A where the anchor bolt 52 and the muscular body 51 intersect with each other as shown in FIG. At this time, when the second gripping portion 21 is pressed against the muscle body 51, the cylindrical portion of the muscle body 51 acts so as to spread the folded piece 24, so that the cylindrical portion of the muscle body 51 is engaged with each of the vertical portions. It is clamped by the stop piece 23. In this state, since the spring force is acting in the direction of sandwiching the muscle 51 in the locking piece 23, each locking portion 25 having a triangular claw shape comes into contact with the surface of the muscle so as to be surely locked. (FIG. 3A).
[0018]
Next, the cylindrical portion of the anchor bolt 52 is inserted into the first grip portion 11. At this time, when the anchor bolt 52 is pressed against the first gripping portion 11, the column portion of the anchor bolt 52 acts so as to spread the bent piece 14, and the column portion of the anchor bolt 52 is engaged with each engagement from the left and right directions. It is clamped by the stop piece 13. In this state, the locking piece 13 is spring-operated in the direction of sandwiching the anchor bolt 52, so that each locking portion 15 having a triangular claw shape comes into contact with the anchor bolt surface so that the locking state is ensured. The anchor bolt 52 crosses the muscle body 51 and can be fixed in the vertical direction (FIG. 3B).
[0019]
Since each connecting piece and each locking piece of the first gripping part 11 and the second gripping part 22 are formed integrally with the base part 10, they have a spring action on the base part 10, Even if the diameters of the members gripped by the first gripping part 11 and the second gripping part 21 are large and small, they can be gripped and the locked state can be maintained. Therefore, the cross-bolt fixing metal fitting having the above-described structure can be used for the crossing portion between the muscle bodies 51.
[0020]
4 and 5 show another example of the cross bolt fixing metal fitting of the present invention, and parts having the same configuration as the cross bolt fixing metal fitting of FIGS. 1 and 2 are denoted by the same reference numerals.
This cross bolt fixing metal fitting is a cross bolt fixing metal fitting formed integrally by bending a T-shaped metal plate 2 as shown in FIG. As a result, the first gripping portion 11 and the second gripping portion 31 are arranged so as to intersect with each other, and as a result, have an appearance as shown in FIG.
That is, this cross bolt fixing bracket is a cross bolt fixing bracket in which a rectangular base 10 and a first gripping portion 11 and a second gripping portion 31 that are connected to the base 10 are integrally formed. In this respect, it is the same as the fixing metal fitting in FIG. 1, and in particular, the first gripping portion 11 has the same configuration.
[0021]
On the other hand, the second grip portion 31 is formed only on one side of the base portion 10. That is, the second grip portion 31 includes a rectangular first connection piece 32 that is bent and connected at a substantially right angle from one side of the base portion 10 in a direction intersecting the first grip portion 11. The rectangular second connection piece 33 bent and connected to the first connection piece 32 at a substantially right angle, and the rectangular connection piece bent and connected to the second connection piece 33 inward. Each locking piece 34, each bending piece 35 which is bent and connected to each locking piece 34 and has a narrower width than the locking piece, and the bending of each locking piece Each locking portion 36 is formed by bending the triangular portion at one corner on the inside.
[0022]
Further, in the base portion 10, a U-shaped hole 37 is provided at a position facing the locking piece 34 and the bent piece 35 of the second gripping portion 31 so as to have a U-shaped notch line 38, and the U-shaped By bending the portion surrounded by the notch line 38 toward the locking piece 34 and the bent piece 35, a support piece 39 protruding toward the locking piece and the bent piece side is formed.
[0023]
The support piece 39 has a base portion that faces the locking piece 33 and the bent piece 34 in the second grip portion 31 even when the second grip portion 31 is formed with the connecting piece 32 or the like only on one side. By forming the support piece 39 at the position, the muscle body is reliably supported by the spring action of the support piece 39. As a result, when the columnar muscular body is gripped from the one direction side by the second gripping portion 31, the locked state can be reliably maintained.
[0024]
This cross bolt fixing bracket is used when two muscle bodies are arranged with respect to the anchor bolt.
That is, in the cross bolt fixing metal fittings of FIGS. 1 and 2, for example, when a plurality of muscle bodies 51 are arranged in close contact like a part B where the muscle bodies 51 and the anchor bolts 52 intersect in FIG. 7. 1, it is difficult to mount the fixing bracket so that the second grip portion 21 sandwiches the muscle 51 in the vertical direction. This is because it is difficult to insert one bent piece 24 of the first gripping portion 11 between the muscle bodies 51 that are already in close contact with each other.
[0025]
According to the cross bolt fixing metal fittings of FIGS. 4 and 5, the second gripping portion 31 that grips the muscle body 51 side is formed with the connecting piece 32 and the like only on the upper side. A fixing metal fitting is disposed on (FIG. 6A). That is, it inserts in the 2nd holding part 31 so that it may cover with respect to the cylindrical part of the muscular body 51 arrange | positioned in a horizontal direction. At this time, when the second gripping portion 31 is pressed against the muscle body 51, the cylindrical portion of the muscle body 51 acts so as to spread the bent piece 35, and the support piece 36 is pressed to act as a spring. Therefore, the cylindrical portion of the muscular body 51 is sandwiched between the locking piece 34 and the support piece 36 from the horizontal direction. In this state, since the spring force acts in the direction in which the muscle 51 is sandwiched in the locking piece 34, each locking portion 36 having a triangular claw shape comes into contact with the surface of the muscle body so that the locking state is ensured. (FIG. 6A).
Therefore, according to the cross bolt fixing metal fitting having the above-described structure, there is an advantage that it is not necessary to position a piece between the muscle bodies 51 and can be easily attached to the muscle bodies 51.
[0026]
The gripping of the anchor bolt 52 is performed in the same procedure as in FIG. That is, when the anchor bolt 52 is pressed against the first gripping portion 11, the column portion of the anchor bolt 52 acts so as to spread the bent piece 14, and the column portion of the anchor bolt 52 is locked from the left and right directions. It is clamped by the piece 13. In this state, the locking piece 13 is spring-operated in the direction of sandwiching the anchor bolt 52, so that each locking portion 15 having a triangular claw shape comes into contact with the anchor bolt surface so that the locking state is ensured. The anchor bolts 52 are crossed with respect to the plurality of muscle bodies 51, and can be arranged and fixed in the vertical direction (FIG. 6B).
[0027]
