Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a metal fitting used when an exterior panel such as an ALC plate or a PC plate that constitutes a curtain wall is attached to a structural frame beam, and in particular, the inclination of the bottom surface of the panel. The present invention relates to a self-weight receiving metal fitting configured by mounting a plate capable of following the above on a horizontal flange.

<Prior Art> Conventionally, when attaching an exterior panel to a structural frame beam, generally, a horizontal flange 1 and a vertical flange 2 are integrally connected in an L shape as shown in FIGS. 9 to 12. The L-type panel self-weight receiving bracket 3 is used, and the vertical flange 2 of the L-type panel self-weight receiving bracket 3 is welded or the Japanese Patent Publication Sho 63-
To fix the bottom surface of the exterior panel 5 with the horizontal flange 2 while fixing it to the ruler angle 4 by means such as hanging a hanging piece provided on the back surface of the L-type panel weight receiving bracket 3 as shown in Japanese Patent No. 29059. Thus, the exterior panel 5 is attached to the frame structure beam via the ruler angle 4.

Also, in FIG. 1 of JP-A-62-78372, a metal plate having a hemispherical protrusion protruding downward is attached to a panel by nailing and placed on an L-shaped panel weight receiving metal fitting. The structure shown in FIG. 5 is shown in FIG. 5, and a metal plate having a groove on the lower surface is attached to the panel by nailing.
Join the plate with the convex strip on the mold panel self-supporting bracket,
A structure is shown in which the panel is placed so that the concave groove is located on the ridge.

<Problems to be Solved by the Invention> However, the exterior panel 5 is attached and fixed to the ruler angle 4 attached to the beam by using the L-shaped panel weight receiving bracket 3 as shown in FIGS. 9 to 12 described above. In this case, as shown in FIG. 9, the horizontal flange 1 of the L-shaped panel weight receiving bracket 3 is horizontally attached in the out-of-plane direction, but when the exterior panel 5 is not vertically attached,
Alternatively, when an external force in an out-of-plane direction due to an earthquake or the like is applied to the exterior panel 5, the exterior panel 5 behaves in the direction of the arrow in the figure, and the contact point between the horizontal flange 1 and the exterior panel 5 becomes one line or one point. However, there is a problem that the lower corner portion of the exterior panel 5 is subjected to a load such as its own weight or a couple force generated by an external force, and this portion is greatly damaged.

As shown in FIG. 10, the exterior panel 5 is also mounted vertically in the out-of-plane direction, but this time, when the horizontal flange 1 is mounted at an angle, the corners are also mounted in the same manner as above. There was a problem that could cause great damage.

Also, as shown in FIG. 11, this time in the in-plane direction,
Although the horizontal flange 1 is mounted horizontally, the exterior panel 5 behaves in the direction of the arrow when the exterior panel 5 is attached in an inclined manner or when an external force in the in-plane direction is applied, and the horizontal flange 1 is attached to one corner portion. Since excessive force is applied, there is a problem that this corner portion is greatly damaged.

Further, as shown in FIG. 12, the exterior panel 5 is mounted vertically in the same in-plane direction as above, but when the horizontal flange 1 is mounted at an angle, one corner is also mounted as described above. There was a problem that the parts could be greatly damaged.

The structure shown in FIG. 1 of JP-A-62-78372 described above not only has the drawback of extra work of previously attaching the metal plate to the panel, but also has a hemispherical projection. Since only the part is in contact with the L-shaped panel weight receiving metal fitting, there is a risk of damaging the panel due to the fact that the panel slips with the metal plate attached during an earthquake and the panels collide with each other.

Further, the structure shown in FIG. 5 of JP-A-62-78372 does not have the disadvantage that it takes extra labor to attach the metal plate to the panel in advance. It is a structure that only rides on the upper part and it is a line contact structure of slippery metal comrades.After all, there is a possibility that the panel slips with the metal plate attached at the time of an earthquake and the panels collide with each other, and the panel is damaged. is there.

The self-weight receiving bracket according to the present invention relates to a completely new technique developed in view of the above-mentioned conventional problems.

<Means for Solving the Problems> The self-weight receiving bracket according to the present invention is a technique that has fundamentally improved the above-mentioned conventional problems, and its gist is a horizontal flange used when attaching an exterior panel to a structural body. And an L-shaped panel weight receiving bracket having a vertical flange,
A plate bottom surface having a downward convex portion is mounted on the horizontal flange by a pin member at the convex portion, and the plate is swingable on the horizontal flange. It is a weight receiving metal fitting that follows.

<Operation> In the present invention, as described above, since the plate having the downward convex portion on the lower surface is mounted on the horizontal flange of the L-shaped panel weight receiving metal fitting by the pin member at the convex portion, the downward convex portion is provided. The plate having the convex portion does not move out of the horizontal flange of the L-shaped panel weight receiving metal fitting, and the panel can be placed in wide contact with the upper surface of the plate, and the plate can be shaken. Since it is movable, the plate can be swung and the plate can be widely and closely contacted with the bottom surface of the exterior panel even when the L-type panel weight receiving bracket or the exterior panel is not horizontal or vertical.

Further, even when the inner surface or the outer surface pressure is applied to the exterior panel due to an earthquake or the like, the plate can be swung so as not to move out of the horizontal flange of the L-shaped panel weight receiving bracket, and the exterior panel's Since the bottom surface is widely and closely contacted with the plate, the panel is held in a stable state without slipping, and it is possible to prevent a large couple of loads from being applied to a part of the exterior panel and prevent damage to the panel. Can be done.

Of course, the L-shaped panel self-weight receiving metal fitting 6 can also be freely tilted in the in-plane direction, so that the entire upper surface of the plate 9 can be brought into close contact with the lower surface of the exterior panel placed on the self-weight receiving hardware.

<Effects of the Invention> When the self-weight receiving member of the present invention is used, a plate having a downward convex portion on the lower surface is mounted on the horizontal flange by a pin member at the convex portion, and the plate swings on the horizontal flange. Since the plate is movable, the plate does not move out of the horizontal flange, and the plate attached to the horizontal flange by the pin member is swingable by the downward convex portion. Since the top surface is flat, the panel can be placed on this plate, and since the panel is held wide and in close contact with the plate, the panel hardly slips even in the event of an earthquake. Also,
Since the upper surface of the plate is flat, it is not necessary to previously form the lower surface of the panel into a special shape.

Of course, a plate having a downward convex portion on the lower surface is attached to the horizontal flange by a pin member at the convex portion, and the plate is swingable on the horizontal flange. The plate can follow the inclination even if it is attached to the side, or the behavior of the exterior panel due to an earthquake or the like, and the weight of the exterior panel can be received on almost the entire upper surface of the plate. Therefore,
It is possible to always receive the weight of the exterior panel evenly, which prevents damage to the corners of the exterior panel.
