The wedge mechanism is composed of a grip wedge and a slide wedge. The grip wedges 1 and 2 are provided with two arms 11 and 21 projecting from the mounting base 3 fixed to the side surface of the abdomen b in parallel with the abdomen b at predetermined intervals, and at their tips. Install. As shown in FIG. 2, the grip wedges 1 and 2 are provided on the outside thereof with the pressure receiving surface 1 parallel to the end face of the cross beam c.

As shown in FIG. 2, both outer surfaces of the slide wedge 4 are formed in a taper shape to form a slide surface 41 that fits between the grip wedges 1 and 2. The surface of the slide surface 41 and the grip surfaces 13, 2 of the grip wedges 1, 2 are
It is preferable that the surface of 3 is made of a combination of Teflon and stainless steel to reduce the frictional resistance and the sliding of the slide wedge 4 is facilitated.

る。FIG. 2 shows a state in which the slide wedge 4 is pushed between the grip wedges 1 and 2. In this case, the grip wedges 1, 2
Is pushed outward, the pressure receiving surface 12 and the end surface of the cross beam c are crimped together, and the transmission surface 23 and the side surface of the raised b are crimped. Therefore, the axial force of the cutting beam c can be adjusted depending on the pushing amount of the slide wedge 4 or the angle of the wedge.
The truss c can be installed by giving an arbitrary axial force. At the time of dismantling the cut c, as shown in FIGS. 3 and 4, the slide wedges 4 are retracted to bring the grip wedges 1 and 2 closer to each other. Then, the pressure receiving surface 1 of the grip wedge 1
Since a gap L is generated between the end face of the truss 2 and the end face of the truss c, and the axial force of the truss c can be released, it can be easily disassembled.
