[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a support mechanism for a wall panel which is arranged above and below an opening such as a window and whose vertical dimension is shorter than usual.

[0002]

[Prior art]

 The wall panels that are placed above and below the opening that does not have a ceiling height, such as windows, are shorter than the normal wall panels depending on the placement position, so one end is supported by the building frame beam. It may not be done. In such a case, one end of the wall panel is usually supported by using a special supporting mechanism in addition to the frame beam.

FIG. 5 is a diagram showing an example of a conventional support mechanism in the above case. In the figure, reference numeral 81 denotes a frame beam vertically provided at a predetermined interval, and the frame beam 81 supports a wall panel P ₁ having a normal size between the frame beam 81 and a frame beam (not shown) above it. It also supports the upper end of the wall panel P whose top and bottom are short. The upper end of this short wall panel P is supported by welding a side angle L-shaped base angle 82 to the upper flange of the frame beam 81, and to the base angle 82, an insulator-shaped bracket 83 fixed in advance to the short wall panel P is attached. Are brought into contact with each other and engaged by welding or the like.

On the other hand, the lower part of the short wall panel P is supported as follows. That is, a reinforcing vertical member 84 is hung from the lower flange of the frame beam 81 at an appropriate interval, a reinforcing horizontal member 85 is installed between the lower ends of the reinforcing vertical member 84, and an angle piece 86 is attached to the horizontal reinforcing member 85. In addition to mounting at appropriate intervals, a through receiving angle 87 is attached between the hanging pieces of the angle piece 86, the lower end of the short wall panel P is placed on the through receiving angle 87, and it is fixed to the lower part of the short wall panel P in advance. This is done by engaging a lower metal member 88 having a lightning shape with a receiving angle 87. A portion below the short wall panel P is an opening such as a window, and a sash or the like is attached.

[0005]

[Problems to be solved by the device]

 However, in the above support mechanism, since the through receiving angle 87 comes into contact with the lower end surface of the short wall panel P and receives the load of the short wall panel P, when the body is shaken by an earthquake or the like, There is a problem that relative displacement and rubbing occur between the lower end surface of the wall panel P and the through-receiving angle 87, and the lower end portion of the short-length wall panel P, which is weak in strength, cracks or cracks, which easily causes chipping. is there. This missing problem is particularly likely to occur when the short wall panel P 1 is made of a material such as lightweight cellular concrete (ALC).

Moreover, since it is difficult to say that the angle piece 86, the through-receiving angle 87, and the like have sufficient rigidity, there is also a problem that the support strength of the wall panel is not sufficient.

The present invention has been made in view of the above-mentioned problems, and a wall panel having a vertical dimension shorter than usual, which is arranged above and below an opening formed of a window or the like, can be used even when an earthquake occurs. It is intended to provide a support mechanism that can support with sufficient strength without fear of the edges being chipped.
