2. Description of the Related Art Conventionally, when building and fixing building panels to a structure of a building, usually, a fastening metal fitting constructed as shown in FIGS. 5 and 6 is used. That is, as shown in FIG. 5, the conventional fastening metal fitting has a slightly thick rectangular steel plate 1 provided with a bent portion 2 having a substantially Z-shaped cross section along the entire length in the widthwise direction at a substantially central portion of the rectangular steel plate. 1 is divided into two steel plate portions 3 and 5 having different phases, and a tightening bolt hole 4 is provided at the center of one steel plate portion 3 with the bent portion 2 as a boundary. In order to build and fix the plates P such as panels to the steel frame S, which is the furring strip of the wall base material of the structure, with the fastening fittings, as shown in FIG. Is fixed to the plate P, and the steel frame S is sandwiched and fixed to the plate P by the other steel plate portion 5 of the fastening metal fitting.

[0003]

However, in the above-mentioned conventional fastening fitting, when the fastening bolt B is loosened due to the rocking or vibration of the building, the fastening fitting is attached to the fastening bolt B side. On the other hand, since the other steel plate portion 5 is heavy, there is a possibility that the other steel plate portion 5 may be detached from the steel frame S and the plate P may be detached by rotating around the fastening bolt B as an axis. Therefore, conventionally, a method of fixing the side edge of the other steel plate portion 5 of the fastening member to the steel frame S by welding W has been performed, but this method is not only complicated and labor-intensive in the work and inspection, but also
Welding may be difficult depending on the arrangement and shape of the steel frame S.

[0004] As means for suppressing the rotation of the above-mentioned conventional fastening fittings, JP-B-58-45365 and JP-B-59-30.
No. 42 has been proposed, but both of these are between the fastening metal fittings, the plate P such as the building panel to which the fastening metal fittings are attached, and the structural base material which is the steel frame S of the other party sandwiched between the fastening metal fittings. This is a rotation preventing means. Therefore, a relative displacement may occur between the two members positioned in the sandwiched state due to a mounting error or vibration such as an earthquake. When the relative displacement exceeds a certain level, the rotation preventing means may not function effectively. is there. The present invention provides a fastening bracket for building panels, which can reliably prevent the rotation of the fastening bracket, which is a drawback of the conventional one, even when a relative displacement occurs between the fastening bracket and the steel frame S. The purpose is to do.

[0005]

The fastening metal fittings for building panels according to the present invention are provided with a bent portion having a substantially Z-shaped cross-section over the entire length in the width direction at a substantially central portion in the longitudinal direction of a rectangular steel plate. The rectangular steel plate is divided into two steel plates having different phases, and the fastening metal fitting main body having a tightening bolt hole at one central portion with the bending portion as a boundary is almost the same as the one steel plate portion. A perforated flat surface portion, and a pair of sandwiching tongues protruding from both side edges along the longitudinal direction of the perforated flat surface portion so as to sandwich both side edges in the width direction of the one steel plate portion, An arm member formed by laterally projecting from one side edge of the perforated flat surface portion along the length direction and bending the tip end at a right angle in a direction opposite to the projecting direction of the sandwiching tongue piece. A plate-shaped auxiliary member including and is assembled.

[0006]

[Operation] Assemble this auxiliary member to the main body of the fastening bracket with the side edges of the plate for the target building panel hooked on the tip of the arm member on the flat surface of the auxiliary member bent at a right angle. . As a result, the perforated flat surface portion of the auxiliary member comes into contact with one of the steel plate portions of the fastening metal fitting body. A pair of sandwiching tongues projecting from both side edges of the perforated flat surface section sandwich both side edges in the width direction of the side edge of one steel plate portion of the fastening metal body. In this state, the fastening metal fitting fastened to the plate is prevented from rotating even if the fastening bolt loosens for some reason.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an exploded perspective view showing an embodiment of the fastening metal fitting of the present invention, FIG. 2 is a front view showing the usage state of the fastening metal fitting of FIG. 1, and FIG. FIG. 4 is a horizontal cross-sectional view as seen from the direction of the line arrow, and FIG. In the figure, 1 is a rectangular steel plate, 2 is a bent portion having a substantially Z-shaped cross section over the entire length in the width direction, 3 is one steel plate portion with the bent portion 2 as a boundary, 4 is a fastening bolt hole, and 5 is a bent portion 2. The other steel plate portion serving as a boundary has a phase different from that of the one steel plate portion 3. The structure, action, and mutual relationship structure of each of these members are substantially the same as those of the conventional fastening metal fittings except that an auxiliary member to be assembled to the fastening metal fitting body described later is provided, and the equivalent portions are the same. It is attached with a code.

Reference numeral 6 denotes a thin plate-shaped auxiliary member to be assembled to the fastening metal fitting main body, and 7 denotes a perforated flat surface portion of the auxiliary member 6, which is substantially the same as one steel plate portion 3 provided with the tightening bolt hole 4. It has a shape. 8a and 8b are perforated plane portions 7
Is a pair of sandwiching tongues projecting from both side edges along the longitudinal direction of the rectangular steel sheet 1 so as to sandwich both side edges in the width direction of the one steel sheet portion 3. Reference numeral 9 denotes an arm portion projecting laterally from one side edge of the perforated flat surface portion 7 along the length direction, 1
Reference numeral 0 denotes a tip portion of the arm portion 9 which is bent at a right angle in a direction opposite to the sandwiching tongue pieces 8a and 8b. The auxiliary member 6 is assembled to the fastening metal fitting body, and the tip portion 10 is hooked on the side edge of the plate P as shown in FIGS. 2 to 4, so that the plate P contacts the other steel plate portion 5 of the fastening metal fitting body. Then, the fastener is attached. At this time, the plates P are arranged with a slight gap as a joint, and since the tip portion 10 is hooked on the side edge of the plate 9, there is no problem in insertion.

In this way, the plate P is attached to the steel frame S via the fasteners, so that the fasteners cannot be rotated about the fastening bolts B even if the fastening bolts B are loosened as in the prior art. . The state in which this rotation is blocked continues even if the relative positions of the steel frame S and the other steel plate portion 5 are changed.

The fastening fitting of the present invention is constructed and functions as described above. When the plates P of panels are fixed to the steel frame S of the furring wall, which is the wall base material of the structure of the building, with the fastening brackets, the fastening bolts and the nuts N are simply tightened as in the conventional case. It suffices to carry out a simple operation of just tightening and fixing to the plate P by means of this, and in this case, the tip end portion 10 of the arm portion 9 of the auxiliary member 6 is caught on the side edge of the plate P, and the sandwiching tongue 8a of the auxiliary member 6 8b holds both side edges of one steel plate portion 3 of the fastener. Therefore, even if the tightening of the tightening bolt B is loosened for some reason, the rotation of the fastening screw with the tightening bolt B as an axis is prevented, and the fastening bracket B does not detach from the steel frame S, and the plate P falls off. There is no danger of danger such as. Furthermore, even if the relative position of the fastening metal fitting to the steel frame S is slightly displaced, the fastening bolt B does not rotate about the tightening bolt B as an axis, and the fastening metal fitting is less likely to come off, which is stable. The wearing state can be secured. Then, by rotating the assembling direction of the auxiliary member, it is possible to cope with the fastening metal fitting main body vertically or horizontally, which is convenient.

[0011]

[Effects of the Invention] The fastening fitting according to the present invention has an extremely simple structure and is easy to handle, and the panels are easily, quickly and economically added to the structure of a tall building that is added to the conventional rectangular steel plate. In addition, it can be securely fixed, and the fixed state is stably maintained.
