【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

The fixing metal fitting of the present invention comprises a locking metal fitting 10 and a locking body 1 which is locked to the lip portion P1 of the lip channel steel P (see FIGS. 1 and 2).

The locking fitting 10 includes a locking portion 11 that locks on the upper surface of the main beam Q1, a connecting portion 12 extending from the locking portion 11 along the side surface of the main beam Q1, and a lower end of the connecting portion 12. The suspension portion 13 that is bent and suspends the stopper 1 is formed of a band-shaped metal fitting. The locking metal fitting 10 of the illustrated example has a pair of beads 14 connected in series to reinforce the strength of each part. Then, the locking nut 1 and the locking body 1 are connected to each other by screwing the seat nut 30 to the hexagonal bolt 20 which is inserted into the upper surface of the suspending portion 13 so that the locking body 1 is known.

The locking body 1 is erected with a pair of reinforcing pieces 3 facing each other at opposite side edges of a connecting plate body 2 which is connected to the locking metal fitting 10 substantially horizontally. Then, the engaging groove 4 is formed in an inclined shape on these reinforcing pieces 3, and the lip portion P1 located above the lip groove section steel P is engaged with the engaging groove 4 (see FIG. 1). ).

The locking groove 4 in the illustrated example is formed by forming an inclined notch from the opening 4A where the lip P1 is located at the crocodile to the bottom 4B where the locking metal fitting 10 connected to the connecting plate 2 is located at the crocodile. ing. The locking metal fitting 10 of the opening 4A is provided with a crimp end 4C for crimping the side surface of the lip P1. The crimping end portion 4C is such that when the locking body 1 is tightened with the locking metal fitting 10, this tightening force becomes the crimping locking force of the crimping end portion 4C (see FIG. 1).

Further, the engaging groove 4 is a contact edge 4D that extends vertically upward from the bottom 4B and is in surface contact with the opening end of the lip P1 at a part of the side edge of the lip P1 and press-contacts. Are formed (see FIG. 4). The contact edge 4D is such that the inner surface of the tip of the lip portion P1 makes surface contact when the locking body 10 of the locking body 1 is tightened.

FIG. 5 shows a state in which the locking body 1 is locked to the lip portion P1 even when the plate thickness of the lip channel steel P is changed. That is, in FIG. 2A, the locking channel 1 is fixed in a substantially horizontal state when the lip channel steel P having the most used thickness is locked. Further, according to FIG. 6B, the plate thickness of the lip channel steel P is increased. In this state, the contact edge 4D does not contact the lip portion P1, but the lip portion P1 is fitted and locked along the groove width of the locking groove 4. Further, according to FIG. 3C, the state in which the lip channel steel P is locked to a thinner one is shown. In this state, the crimping end portion 4C and the abutting edge 4D act together so that even a thin lip channel steel P can be connected and fixed. At this time, in the cases of (b) and (c) of the figure, although the locking body 1 is in a slightly inclined state as compared with the horizontal state, the locking metal fitting 10 and the locking body 1 are not connected to each other. By attaching a washer 12 which is integral with the stop nut 11 or is a separate body, the locking metal fitting 10 can be connected vertically.

[0018]

[Effect of device]

 The present invention achieves the original purpose by being configured as described above.

That is, according to claim 1, it has an extremely stable connecting force and can be used regardless of the size of the lip channel steel, and the fixing metal fitting itself is provided in an extremely compact size. can do. From this, it is possible to eliminate many inconveniences that occur in terms of storage space, transportation work, or manufacturing cost, unlike the conventional large-sized fixture 50.

According to the second and third aspects of the present invention, the locking force of the fixing metal fitting of the present invention can be increased and a reliable connection fixing force can be obtained.

Further, according to the third aspect, the locking groove 4 of the locking body 1 can be prevented from being deformed and can be adapted to a wide range of plate thickness.

As described above, according to the present invention, it is possible to use the lip channel steel regardless of its size, and the fixing metal fitting itself is compact, so that a reliable connecting and fixing force can be obtained. It has various beneficial effects.
