Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an outer wall panel constructed by attaching a face plate to an outer surface of a metal frame body.

[0002]

2. Description of the Related Art Conventionally, there has been known an outer wall panel in which a face plate such as an ALC plate is attached to the outer surface of a metal frame. In this conventional outer wall panel, the face plate is fixed to the outer surface of the metal frame by screws or bolts. Then, the outer wall panel having such a structure is fixed to a structural material such as a pillar, a beam, and a base of the building to form an outer wall of the building.

[0003]

However, when a horizontal force acts on a building during an earthquake or the like, in the conventional outer wall panel described above, the face plate itself breaks at the portion where the face plate is attached to the frame when the building is deformed. There was a problem. The present invention has been made in view of the above problems of the conventional example, and an object of the present invention is to provide a structure of an outer wall panel capable of preventing the face plate from being broken during an earthquake.

[0004]

According to the structure of the outer wall panel of the present invention, in the outer wall panel 3 formed by attaching the face plate 2 to the outer surface of the metal frame 1 by the attaching means, the horizontal frame 4 of the frame 1 is formed. A lateral frame 4 is sandwiched between a back surface of the face plate 2 and a holding metal fitting 5 which constitutes an attachment means attached to the back face side of the face plate 2 while abutting the face plate 2 on the outer surface. By adopting such a configuration, the problems of the conventional example described above are solved and the object of the present invention is achieved.

[0005]

According to the present invention having the above-mentioned structure, the holding metal plate 5 and the face plate 2 that make the mounting means attached to the outer surface of the lateral frame 4 of the frame body 1 and attached to the back side of the face plate 2 are in contact with each other. When the horizontal frame 4 is clamped between the rear surface of the base plate and the horizontal frame 4 when the horizontal force is applied during an earthquake or the like, stress is applied to the face plate 2 by moving the clamping metal fitting 5 that constitutes the mounting means with respect to the horizontal frame 4. It can be prevented.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in the accompanying drawings. The frame 1 made of metal such as iron is a vertical frame 12 on the left and right.
Upper and lower and middle horizontal frames 4 are installed between them. The vertical frame 12 and the horizontal frame 4 are U-shaped in cross section. Here, the upper horizontal frame 4 is arranged so that the opening portion faces downward, and the lower horizontal frame 4 is arranged so that the opening portion faces upward.
The face plate 2 is formed of a material containing cement as a main component, such as ALC, and the iron plate 6 is embedded inside. The embedded positions of the iron plate 6 are embedded in the upper part, the middle part and the lower part of the face plate 2, respectively. There is. On the back of this face plate 2 is an upper part,
The clamping metal fittings 5 constituting the mounting means are attached to the intermediate portion and the lower portion by screws 7, respectively. In this case, the tip of the screw 7 is screwed to the iron plate 6 embedded inside. As shown in FIG. 3, the holding metal fitting 5 is constituted by connecting a holding piece 10 parallel to the fixed piece 9 through a step 9 from the end of the vertical fixed piece 8. Then, the fixing piece 8 is brought into contact with the back surface portion of the face plate 2, and the screw 7 is inserted through the hole provided in the fixing piece 8 to attach the holding metal fitting 5 to the back surface portion of the face plate 2.

Then, the face plate 2 is brought into contact with the outer surface of the metal frame body 1, and the holding piece 10 of the holding metal fitting 5 is applied to the inner surface side of the side piece 11 on the outer surface side of the lateral frame 4 of the frame body 1. The face plate 2 is attached to the frame body 1 by pinching the side piece 11 on the outer surface side of the lateral frame 4 between the holding metal fitting 5 and the back surface of the face plate 2 by tightening the screw 7 in this state. Here, as shown in FIG. 1, the holding piece 10 of the holding metal fitting 5 for holding the lower horizontal frame 4 is held.
Is directed downward, and the clamping piece 10 of the clamping metal fitting 5 for clamping the upper horizontal frame 4 is directed upward.

At the time of attaching the holding metal fitting 5 to the face plate 2, the holding metal fitting 5 is attached to the face plate 2 at the same time when the face plate 2 is attached to the frame body 1, and the holding piece 10 of the holding metal fixture 5 and the face plate 2 form the frame body. The side piece 11 of No. 1 may be clamped. Alternatively, the clamping metal fitting 5 may be attached to the back side of the face plate 2 in advance with the screws 7 slightly loosened, and the clamping metal piece 1 of the clamping metal fitting 5 may be clamped.
When the side piece 11 of the frame body 1 is sandwiched between 0 and the face plate 2, a screw 7
May be fully tightened. In any case, the tip of the screw 7 is screwed into the iron plate 6 embedded in the face plate 2 as described above to improve the attachment strength of the screw 7.

As described above, the outer wall panel 3 is constructed by mounting the face plate 2 on the frame body 1 by sandwiching it with the sandwich metal fittings 5. The assembly construction of the outer wall panel 3 is completed in advance in the factory, and Is transported to the site and the outer wall panel 3 is fixed to the structural material such as the pillars, beams, and foundations of the building at the site to form the outer wall of the building. Then, when horizontal stress due to an earthquake or the like acts on the building, since the side piece 11 of the lateral frame 4 is held between the holding piece 10 of the holding metal fitting 5 and the back surface of the face plate 2, the holding portion is attached to the side piece 11. On the other hand, side piece 11
As a result, the horizontal stress is not directly applied to the mounting portion of the face plate 2 to the frame body 1, so that the face plate 2 can be prevented from being damaged.

[0010]

As described above, according to the present invention, the sandwiching metal fitting and the back surface of the face plate that make up the attachment means attached to the outer surface of the lateral frame of the frame body and attached to the back surface side of the face plate are provided. Since the horizontal frame is sandwiched between them, when a horizontal force is applied during an earthquake etc., the clamping plate that constitutes the mounting means moves with respect to the horizontal frame so that stress is not applied to the face plate and the face plate is damaged. Can be prevented.
