A pair of the reinforcing plates 2, 2 which are constituted by the slit portions 8b, 8b, and whose direction of hand is selected in the engaging groove 8, are engaged with each other so as to overlap with each side wall of the engaging groove 8 as described above. The horizontal members 1 (ends 1 'thereof) are fixed to each other with a gap b therebetween. That is, the reinforcing plate 2 has a rear end portion fitted into the slit portion 8b of the engagement groove 8 and a front end portion disposed in the groove portion 8a, and the reinforcing plate 2 is transversely connected to the second through hole 6A provided on the rear end side. The second fitting holes 7A provided on the material 1 side are made to coincide with each other, and the fixed rod 9 constituted by the drift pin is fitted to these, and the first through hole 6 and the topmost one of the first fitting holes 7 which match each other. The first latching rods 3, which are the uppermost latching rods composed of drift pins, are driven into each of them, and are fitted and fixed to the ends of the horizontal members 1 with a gap b therebetween.
[0014]
The first and second protrusions 5 and 5A penetrate the structural material 10 and are connected to a screw portion 11 protruding from the structural material 10 by screwing a nut 12 to a head side of a bolt rod 13. And the longitudinal direction is set on the side surface (the surface facing the horizontal member 1) of the structural material 10 in a positional relationship set relatively to the gap b or the first through hole 6 or the first insertion hole 7. The first protruding member 5 includes the first latching rod 3 (the uppermost first through hole 6 and the first fitting insertion hole 7), and the second protruding member 5A except for the uppermost one. The first through hole 6 (6a, 6b) and the other first fitting holes 7 (7a, 7b) except for the uppermost one are protruded from the structural material 10 respectively.

The tapered edges a, a ′ (formed of a truncated conical body) serve to pull the transverse member 1 in the direction of the structural material 10, and the first hook 5 is attached to the tapered edge a of the first protrusion 5. When the rod 3 is mounted, the inclination of the rod 3 causes the hanging rod 3 to move in the direction of the structural member 10 while descending, so that the horizontal member 1 on which the reinforcing plate 2 is attached is drawn in the direction of the structural member 10, and In the case of the tapered edge a 'of the second protrusion 5A, the first through-hole 6 (6a, 6b) (the uppermost one) is formed in the joint fitting A so that a part of the tapered edge a' overlaps. When the second locking rod 3A or the locking rod 4 is inserted through the first through hole 6 (6), the locking rod 3A or the locking rod 4 relatively presses the tapered edge a '. , 6b), and the tapered edge a 'pressed by the second latching rod 3A or the like, that is, the second protruding member 5A is in the fixed state, so that the lateral side on which the second latching rod 3A or the like is assembled. The bridge 1 moves in the direction of the structural member 10, and the horizontal member 1 is drawn in the direction of the structural member 10.
[0016]
In addition, although the tip parts 5 'and 5'A of the protrusions 5 and 5A of the embodiment are constituted by the heads of the bolt rods 13 as described above, they hold the intermediate parts of the protrusions 5 and 5A. Due to the separation width (distance) between the engaging rod 3 or 3A and the engaging rod 4, the distal end portions 5 'and 5'A can always be arranged at a wide large-diameter position (the bolt rod 13 is There is no change in the diameter at any rotation angle in the rotation direction), that is, it is not necessary to select the directionality. In this sense, it is complicated to attach the protruding members 5, 5A (bolt rod 13) to the structural member 10. Can be avoided. Therefore, if this complication is neglected, the tip portions 5 ', 5'A of the protruding members 5, 5A may be of a substantially T-shape in side view, in which only the upper end and the lower end thereof are protruded. May be omitted.

When the horizontal member 1 is lowered along the side surface of the structural member 10 so as to be engaged, the first latching rod 3 arranged on the upper side of the gap b is hooked on the first protrusion 5, The member 1 is received by the first protrusion 5 via the retaining rod 3 and is temporarily joined to the structural member 10. In this state, the second latching rod 3A is driven into the first through hole 6 (6a, 6b) and the first fitting insertion hole 7 which are in communication with each other, and when the second latching rod 3A is inserted, the second latching rod 3A becomes the horizontal member 1 , And is disposed at a position where it is fixed and received by the second protruding member 5A, and the load on the horizontal member 1 is applied to the second protruding member 5A, thereby obtaining load resistance.
[0018]
The locking rod is inserted into the lowermost first through hole 6 (indicated by reference numeral 6b) and the first fitting insertion hole 7 (indicated by reference numeral 7b) immediately before and after the driving operation of the second latching rod 3A. 4, the locking rod 4 is placed laterally on the horizontal member 1 at a position in contact with the lower edge of the lowermost second protrusion 5A, and an external force is applied to the horizontal member 1 from below. At this time, the locking rod 4 is locked to the lowermost second projection 5A to prevent the horizontal member 1 from being lifted, and at the same time, the lowermost second projection 5A is Since the intermediate portion is sandwiched by the second latching rod 3A, even if an external force is applied to the horizontal member 1 in the direction of separating from the structural member 10, the large diameter of the second protrusion 5A can be obtained. Due to the presence of the extreme tip 5'A, the above-described holding state is maintained, and the horizontal member 1 is prevented from being detached from the structural member 10.
[0019]
