Description

[Brief explanation of drawings]

Fig. 1 is a perspective view of the overall structure of the fastening fitting according to this embodiment in a separated state before fastening, Fig. 2 is a perspective view of the same in the fastened state, and Fig. 3 shows the zygote and the core. Fig. 2 shows the planar cross-sectional state at the time of completion of fastening and in the middle of insertion;
The figure shows the axial cross-sectional state before and after the completion of fastening between the zygote and the core. Figure 2 is a view from the direction of the arrows. Figure 5 shows the fastening of the core when the position between the zygote and the core is shifted in the Y direction. Fig. 2 shows the condition, Fig. 6 and Fig. 7 show the fastening state of the core when the position between the zygotes is shifted in the X direction. The figure shows the planar arrangement of the zygotes, and the segments are viewed from the inner wall side. FIG. FIG. 11 is an end view of the joint in the joined state showing the joined state of the joint in the off-center state, and FIG. 11 is a perspective view of the joint in the separated state showing the structure of a conventional fastening fitting.

Claims (1)

[Claims for Utility Model Registration] Mainly, at each connecting portion of two segments to be connected, a pair of segments that are integrally fixed to the segments so that the axes are parallel to the contacting surfaces and the lip portions face outward. The general shape of each main part is formed by bringing the zygotes of the C-shaped channel-shaped body and the zygotes of the two segments to be connected into contact with each other at each clip portion of the C-shaped channel-shaped body, facing each other. In the space of the roughly H-shaped steel body,
The main part is inserted in the axial direction, has a play at the beginning of insertion, and when the insertion is completed, clamps both the zygotes and fastens the two zygotes.The main part is composed of a core whose general cross-sectional shape is H-shaped. A fastening fitting for fastening between the segments constituting the wall surface, which connects the inner surface of the lip portion of the C-shaped channel-like body of the connector with the inner surface of the web portion and the inner surface of the lip portion on the tip side. The taper surface is formed with a slope in the direction of narrowing the gap between the lip part and the other joint to form a wedge hole in the axial direction that narrows at the tip, and the other joint faces and abuts against the joint surface of the lip part. A meshing portion having tooth-shaped teeth narrow at the tip and wide at the root for axial engagement is formed, and the inner surface of the flange portion of the H-shaped steel body of the core is A fastening in which the core is provided with a wedge piece in the axial direction that tapers at the tip by forming a tapered surface with a slope in the direction in which the gap between the flange portions widens on the tip side corresponding to the tapered surface of the lip portion. In the metal fitting, the outer end of the engaging portion is formed into a flat shape from the distal end to the proximal end on the joint surface of the lip portion, and the connecting portion of the connecting joint is formed between the engaging portions of the engaging joints. A fastening metal fitting characterized in that a clearance is provided in the axial direction of the joint and in a direction perpendicular thereto so that the joint can freely move in the X and Y directions within a plane.
