Next, the connection between the vertical frame 1 and the horizontal rod 10 will be described. (See FIG. 2) The screw portions 23 of the connection screws 20 are screwed into the screw holes 13 of the horizontal frame 10 and attached. The screw head 21 of the connecting screw 20 of one horizontal frame 10 is inserted into the through hole 4 of one horizontal plate mounting plate 2.
And temporarily hold the washer 24 by fitting it. A first wedge fitting 30 ₁ Slide the hollow inner surface of the vertical frame 1 as a guide, bis head 21 the wedge piece 33 by fitting the vertical groove 32 in the axial rod portion 22 of the connecting screw 20 and the lateral frame mounting plate 2 Press into the inner surface of The screw head 21 of the connecting screw 20 of the other horizontal frame 10 is inserted into the through hole 4 of the other horizontal plate mounting plate 2.
And temporarily hold the washer 24 by fitting it. The second wedge brackets 30 ₂ first wedge bracket 30 ₁ of the vertical frame 31 and the other lateral杆取with plate 2
Is guided and slid, and the vertical groove 32 is fitted into the shaft rod portion 22 of the connecting screw 20 to insert the wedge piece 33 between the screw head 21 and the inner surface of the horizontal frame plate mounting plate 2. FIG . 3 shows a first embodiment, in which guide pieces 5 are provided on the inner surfaces of a pair of connecting plates 3 of a vertical frame 1.
5 are continuously formed in the longitudinal direction so as to face each other, and the vertical plate 31 of the wedge fitting 30 has a cross-sectional shape that slides along one of the guide pieces 5 and 5 and the one horizontal frame mounting plate 2, and the wedge fitting 30 is formed. Slide along the guide pieces 5, 5 to fit the vertical groove 32 to the shaft rod portion 22 of the connecting screw 20, and to insert the wedge piece 33 between the screw head 21 and the inner surface of the one horizontal frame mounting plate 2. Press in. FIG. 4 shows a second embodiment, in which the vertical plate 31 of the wedge fitting 30 is made short, and the wedge fitting 30 is slid along a pair of guide pieces 5 and 5 by a pushing jig 34 such as a plate. It is. FIG. 5 shows a third embodiment, in which a horizontal frame 10 is provided at the longitudinal end of the vertical frame 1 and at the middle in the longitudinal direction.
The through holes 4 are formed in one of the horizontal frame mounting plates 2 of the vertical frame 1 so as to be vertically separated from each other, and vertical grooves 32 are formed above and below a long vertical plate 31 of the wedge fitting 30. A screw head insertion hole 34 continuous with the vertical groove 32 is formed, and the upper and lower screw head insertion holes 34 are formed.
, 34 are the same as the distance between the centers of the upper and lower through holes 4, 4. Then, when connecting, the wedge fitting 30 is slid along the guide piece 5 of the vertical frame 1 so that the screw head insertion hole 34 matches the through hole 4. In this state, the screw head 21 of the connection screw 20 screwed into the upper and lower horizontal frames 10 is inserted into the screw head insertion hole 34 through the through hole 4 so that the shaft rod portion 22 faces the groove portion 32, and the wedge metal fitting 3
Further, the wedge pieces 33 are press-fitted between the respective screw heads 21 and the inner surface of the horizontal frame mounting plate 2 by sliding the vertical groove 32 into the shaft rod portion 22 of the connecting screw 20 by further sliding the zero. In FIG. 5, the distance between the centers of the upper and lower screw head insertion holes 34, 34 is made shorter than the distance between the centers of the upper and lower through holes 4, 4, and the wedge fitting 30 is connected to the guide piece 5 of the vertical frame 1. To align the lower screw head insertion hole 34 with the lower through hole 4. In this state, the screw head 21 of the connecting screw 20 of the lower horizontal frame 10 is inserted into the screw head insertion hole 34 below the lower through hole 4 and the wedge fitting 30 is slightly slid to insert the upper screw head. The hole 34 matches the upper through hole 4, and the screw head 21 of the connecting screw 20 of the upper horizontal frame 10 is inserted into the screw head insertion hole 34 above the upper through hole 4, and the wedge fitting 30 is inserted. Further slide and connect. Further, the screw head insertion hole 34 on the wedge fitting 30 may be a vertically long hole. Further, it may be divided wedge bracket 30 as shown in FIG. 6 above and below, may be constituted from upper and lower wedge bracket 30 _3, 30 ₄ and a connecting fitting 30 ₅ intermediate 7.
