Field of the Invention The present invention relates to a structure for connecting a vertical frame and a horizontal frame using wedge fittings. 2. Description of the Related Art There are known various types of structures for connecting a vertical frame and a horizontal frame using wedge fittings. For example, as shown in Japanese Utility Model Publication No. 49-38348, a connecting screw having a washer inserted into a screw hole of a vertical frame is screwed in, and a screw head of the connecting screw and a washer are inserted into a through hole of a horizontal frame. It is known that a wedge fitting is press-fitted between the screw head and the horizontal frame to connect the vertical frame and the horizontal frame. With such a connecting structure, the washer inserted in the connecting screw is fitted into the through hole of the horizontal frame to temporarily hold the vertical frame and the horizontal frame so as not to move slightly. Therefore, for example, as shown in FIG. 1, a through hole 3 is formed in the horizontal frame mounting plate 2 of the vertical frame 1, and a screw hole 6 is formed in the horizontal plate 5 of the horizontal frame 4.
The connecting screw 8 into which the washer 7 is inserted is screwed into the screw hole 6, and the washer 7 is inserted into the through hole 3. The screw head 8 a of the connecting screw 8 and the inner surface of the horizontal frame mounting plate 2 of the vertical plate 1 are formed. 2
When the wedge fitting 9 is press-fitted between the vertical frame 1 and the vertical frame 1 and the horizontal frame 4,
As shown in FIG. 2, the center 6a of the screw hole 6 is separated from the horizontal plate 5 by the radius of the through hole 3, so that the rising piece 5a is integrally formed on the horizontal plate 5, and the screw hole 6 is formed in the rising piece 5a. . For this reason, the material of the horizontal frame 4 is required to be extra by the rising pieces 5a, so that the material cost is increased and the cost is increased. Therefore, an object of the present invention is to provide a connecting structure of a vertical frame and a horizontal frame which can solve the above-mentioned problem. Means for Solving the Problems A screw insertion hole formed in a horizontal frame mounting plate 11 of a vertical frame 10 by a large-diameter hole 13 and a vertically long narrow hole 14 continuous with a part of the large-diameter hole 13. 12 and the screw insertion hole 12 is formed.
A projection 15 is provided at an upper position, and a screw hole 23 is continuously formed in the horizontal plate 21 of the horizontal frame 20 in the longitudinal direction. A screw head 31 having a smaller diameter than the large-diameter hole 13 and a smaller diameter than the screw head 31 are provided. And a connecting screw 30 having a shaft rod portion 32 and a screw portion 33 having the same diameter as the narrowing hole 14 and a wedge fitting 40, and a locking piece is provided on the side of the horizontal frame 20 facing the vertical frame 10.
24, the screw portion 33 of the connection screw 30 is screwed into the screw hole 23 of the horizontal frame 20, the screw head 31 of the connection screw 30 is inserted into the large-diameter hole 13, and the shaft rod portion 32 is squeezed. The vertical frame 10 and the horizontal frame 20 are temporarily held by fitting into the holes 14, and the horizontal frame mounting plate 11 of the vertical frame 10 is
A wedge fitting 40 is press-fitted between the inner surface of
0, one end surface 20a in the longitudinal direction is butt-connected to the outer surface 11b of the horizontal frame mounting plate 11 of the vertical frame 10 so that the projection 15 comes into contact with the upper surface of the locking piece 24. . The shaft portion 32 of the connecting screw 30 is fitted into the narrowing hole 14 of the screw insertion hole 12 and the center of the connecting screw 30 is separated from the center of the large diameter hole 13 of the screw insertion hole 12. The screw holes 23 of the horizontal frame 20 can be formed directly and integrally with the horizontal plate 21, eliminating the need for rising pieces as in the prior art, thereby reducing the material cost of the horizontal frame 4 and the cost. As shown in FIG. 3, a pair of screw insertion holes 12, 1 are formed in a horizontal frame mounting plate 11 of a vertical frame 10.
2 are formed at intervals in the width direction, and the screw insertion holes 12
It is composed of a vertically elongated narrow squeeze hole 14 continuous with a part of the large diameter hole 13. A pair of projections 15 in the width direction are provided above the screw insertion holes 12 in the horizontal frame mounting plate 11 of the vertical frame 10, and the projections 15 are formed by cutting a part of the horizontal frame mounting plate 11 into a U-shape and punching out. It is provided integrally. The horizontal frame 20 is formed in an upward U-shape by a horizontal plate 21 and a pair of vertical plates 22, 22 provided integrally at both ends in the width direction of the horizontal plate 21, and a screw hole 23 is formed in the horizontal plate 21 in the width direction. Locking pieces 24 are integrally formed opposite to each other on the pair of vertical plates 22, 22. The connecting screw 30 includes a screw head 31, a shaft rod 32 having a smaller diameter than the screw head 31, and a shaft rod 3.
4, the screw 33 is screwed into the screw hole 23, and the shaft 34 and the step 34 of the screw 33 come into contact with the opening end face 23a of the screw hole 23 as shown in FIG. ing. The wedge fitting 40 is formed by forming a pair of vertical grooves 42 on a vertical plate 41 and projecting wedge pieces 43 and 43 integrally on both side edges of each vertical groove 42. The connection between the vertical frame 10 and the horizontal frame 20 will be described. As shown in FIG. 4, the screw portion 33 of the connecting screw 30 is screwed into the screw hole 23 of the horizontal frame 20 to project the shaft rod portion 32 and the screw head 31. The horizontal frame 20 is moved in the horizontal direction toward the vertical frame 10 to insert the screw head 31 of the connecting screw 30 into the large-diameter hole 13, and the horizontal frame 20 is moved downward to make the shaft rod portion 32 a narrow hole. 14, the vertical frame 10 and the horizontal frame 20 are positioned and temporarily held so as not to slightly move in the width direction. The vertical groove 42 of the wedge fitting 40 is inserted into the shaft rod portion 32, and the wedge fitting 40 is press-fitted between the screw head 31 and the inner surface 11 a of the horizontal frame mounting plate 11 so that one end face 20 a in the longitudinal direction of the horizontal frame 20 is fixed. It is butt-connected to the outer surface 11b of the horizontal frame mounting plate 11 of the vertical frame 10. In FIG. 4, they are butted through a sealer 50. Thus, the protrusion 15 provided on the horizontal frame mounting plate 11 of the vertical frame 10 can be prevented from coming into contact with the upper surface of the locking piece 24 of the horizontal frame 20 so that the horizontal frame 20 comes off in the longitudinal direction of the vertical frame 10. The shaft portion 32 of the connecting screw 30 is fitted in the narrow hole 14 of the screw insertion hole 12, and the center of the connecting screw 30 is separated from the center of the large diameter hole 13 of the screw insertion hole 12. Therefore, the screw holes 23 of the horizontal frame 20 can be directly formed integrally with the horizontal plate 21, and the rising pieces are not required as in the related art, so that the material cost of the horizontal frame 4 can be reduced and the cost can be reduced. Also, the vertical frame 10
The protrusion 15 provided on the horizontal frame mounting plate 11 contacts the upper surface of the horizontal frame 20 locking piece 24 and the horizontal frame 20 is
It is possible to prevent the vertical frame 10 from coming off in the longitudinal direction.
