SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to insert a pin of a joint bolt or a pin of a fastener into a through hole in a locking surface of a fastener for an outer wall panel. It is easy to do this, and even if the screw part of the bolt that attaches the fastener for the outer wall panel does not rotate with a strong force such as an earthquake, the lower part of the outer wall panel is moved up and down accurately by following the movement of the earthquake or the like. It is an object of the present invention to provide a fastener for an outer wall panel.

[0011]

In order to achieve the above object, a fastener for an outer wall panel according to the present invention is applied to a building such as a house constructed by a curtain wall method, in which a lower part of the outer wall panel is formed by a beam, an upper part of an foundation or an ALC. And has a right-angled locking surface and a mounting surface. The locking surface is provided with a through hole, and the mounting surface is provided with the locking surface. A long hole through-hole is provided in a direction perpendicular to the surface, and two projecting pieces formed on the back surface of the mounting surface on both sides of the long hole in a longitudinal direction of the long hole. Is a fastener for an outer wall panel at a position symmetrical with respect to the elongated hole as an axis.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2, the outer wall panel fastener F has an L-shape formed by bending a single metal plate at a right angle. Constituting this L-shape 2
The surfaces are a locking surface 1 and a mounting surface 2. The locking surface 1
Is provided with a through hole 3 near its center. In the vicinity of the center of the mounting surface 2, a through hole of a long hole 4 long in a direction perpendicular to the locking 1 is provided. Further, on the back surface 2a of the mounting surface 2, a total of four projecting pieces 5 are formed on both sides of the elongated hole 4 at positions symmetrical with the elongated hole 4 as an axis. These protruding pieces 5 are formed by stopping the extrusion process halfway.

Next, attachment of the outer wall panel fastener F will be described. The outer wall panel fastener F is attached using a groove rail bolt 12 having one screw portion. For this attachment, as in the prior art, the groove rail 1 is inserted from the side end of the outer wall panel 10 as shown in FIG.
1 may be used, but as shown in FIG. 3, the groove rail bolts 12 are modified so that the groove rails 11 can be seen from the front of the rear surface of the outer wall panel 10.
May be used. That is, in the improved groove rail bolt 12, a part of the head is smaller than the width of the opening of the groove rail 11 so that the head is mounted on the groove rail 11 from the front, and the head after mounting is formed. It is rotated inside the groove rail 11 so as to be hooked so as not to come off in the direction perpendicular to the back surface of the outer wall panel 10. For example, the head has a rectangular plate shape, and one part of the four corners is cut out or is an ellipse or an ellipse so as to be easily rotated inside the groove rail 11.

First, the fastener F for the outer wall panel is shown in FIG.
As shown in (1), the thread portion of the groove rail bolt 12 is inserted into the elongated hole 4 of the mounting surface 1, and is temporarily shifted upward using the elongated hole 4 and temporarily fixed. Thereafter, the outer wall panel 10 is hung by a crane or the like, and the upper portion of the outer wall panel 10 is attached to the beam.

When the upper portion of the outer wall panel 10 is attached to the beam, the fastening surface 1 of the outer wall panel fastener F is fixed.
Are the pin 40a of the joint bolt 40 and the fastener 4
1 are located above the pins 41a, and these pins 4a
0 a and 41 a have not yet been inserted into the through-hole 3.

Then, as shown in FIG. 5, the fastener F for the outer wall panel which has been temporarily fixed is shifted downward,
The projecting pieces 5 are all arranged in the openings of the groove rails 11, and the pins 40 a of the joint bolts 40 and the pins 41 a of the fastener 41 are inserted into the through holes 3 of the locking surface 1.
Is inserted and tightened with a nut 13 for mounting.

As described above, the insertion of the pins 40a and 41a into the through holes 3 of the locking surface 1 is not performed while gradually lowering the outer wall panel 10, but the upper part of the outer wall panel 10 is attached to the beam. Since the outer wall panel 10 is stable, it is easy to insert the pins 40a and 41a into the through holes 3 of the locking surface 1 and the outer wall panel fastener F and the outer wall panel 10 are damaged. There is no danger.

In FIG. 6, when a strong force is applied due to an earthquake or the like and the pins 40a and 41a move in the longitudinal direction X of the groove rail 11, the fastener F for the outer wall panel becomes the screw portion of the bolt 12 for the groove rail. To rotate in the circumferential direction R around the axis, but the protruding piece 5 is
At 1a, the rotation is stopped.

As described above, since the projecting piece 5 stops the rotation of the outer wall panel fastener F, even if only one screw portion of the groove rail bolt 12 is used, the rotation is prevented beforehand. Moves up and down as expected.

Also, since the projecting piece 5 stops the rotation of the outer wall panel fastener F, it is not necessary to use two or more threaded portions of the groove rail bolts 12 in order to prevent the rotation from occurring. The number does not increase, and the workability of mounting the outer wall panel fastener F does not deteriorate.

The projecting piece 5 hits the edge 11a of the opening of the groove rail 11, so that the outer wall panel fastener F is prevented from rotating in the circumferential direction R around the threaded portion of the groove rail bolt 12. It plays a role, and if it plays the same role, its shape, arrangement, etc. may be other. This modification is shown in FIG.
Shown in

This modified example is a fastener F for an outer wall panel, which also protrudes between two projecting pieces 5 formed above the above-described embodiment to form one projecting piece 5, and has a vertically projecting portion. Each of the pieces 5 hits respective upper and lower edges 11a of the opening of the groove rail 11, and the outer wall panel fastener F
Stop the rotation of.

[0023]

As described above, according to the fastener for an outer wall panel of the present invention, since the mounting surface is provided with the elongated hole, the fastener for the outer wall panel is shifted upward using the elongated hole. After the upper part of the outer wall panel is attached to the beam, the pin can be inserted into the through hole in the locking surface of the fastener for the outer wall panel, so that the insertion work is simple, and the outer wall can be easily fixed. There is no risk of panel fasteners or exterior wall panels being damaged.

Further, since the projecting piece hits the edge of the opening of the groove rail and stops the rotation of the fastener for the outer wall panel, the rotation can be prevented even if only one screw portion of the groove rail bolt is used. In the case of an earthquake or the like, the lower part of the outer wall panel moves up and down as expected.

Further, since the projecting piece hits the edge of the opening of the groove rail to stop the rotation of the fastener for the outer wall panel, the rotation of the bolt for the groove rail is prevented without using two or more screws. Can be prevented and the number of nuts used for mounting does not increase, so only one nut is required.
The workability of mounting the fastener for the outer wall panel does not deteriorate.
