BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support mechanism for a wall panel which is disposed above and below an opening formed of a window or the like and whose vertical dimension is shorter than usual.

[0002]

2. Description of the Related Art A wall panel disposed above and below an opening which does not have a ceiling height, such as a window, is shorter than an ordinary wall panel depending on the arrangement position. May not be supported by frame beams. In such a case, one end of the wall panel is usually supported using a special support mechanism in addition to the frame beam.

FIG. 5 is a view showing an example of a conventional support mechanism in the above case. Figure 81 is a skeleton beam provided with a predetermined interval in the vertical direction, the precursor beam 81 supports the wall panel P ₁ of the normal dimension between the skeleton beam above it (not shown), also It supports the upper end of the wall panel P whose top and bottom are short. To support the upper end of the short wall panel P, a base angle 82 having a substantially L-shaped side surface is welded to the upper flange of the frame beam 81, and a snap fastener 83 previously fixed to the short wall panel P is fixed to the base angle 82. This is done by bringing them into contact and engaging them by welding or the like.

On the other hand, the lower part of the short wall panel P is supported as follows. That is, the reinforcing uprights 84 are hung at appropriate intervals from the lower flange of the skeleton beam 81, a reinforcing horizontal member 85 is erected between the lower ends of the reinforcing uprights 84, and the angle pieces 86 are further spaced at the horizontal reinforcing members 85 at appropriate intervals. At the same time, a through-angle 87 is attached between the hanging pieces of the angle piece 86, and the lower end of the short wall panel P is placed on the through-angle 87, and is fixed to the lower portion of the short wall panel P in advance. Lower hardware 8
8 is engaged with the receiving angle 87. The portion below the short wall panel P is an opening such as a window, and a sash or the like is attached.

[0005]

However, in the above-mentioned supporting mechanism, the through-angle 87 is formed by the short wall panel P.
When the skeleton shakes due to an earthquake or the like due to contact with the lower end surface of the short wall panel P and the frame is shaken due to an earthquake or the like, relative displacement and friction between the lower end surface of the short wall panel P and the through receiving angle 87 are caused. This causes a problem that the lower end portion of the short wall panel P, which is weak in strength, is easily broken or cracked to be dropped. This problem of dropout is particularly likely to occur when the short wall panel P is made of a material such as lightweight cellular concrete (ALC).

In addition, since the rigidity of the angle piece 86 and the through-angle 87 cannot be said to be sufficient, there is a problem that the supporting 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 shorter vertical dimension than usual, which is disposed above and below an opening formed of a window or the like, can be used even in the event of an earthquake or the like. An object of the present invention is to provide a support mechanism capable of supporting with sufficient strength without fear of a part being dropped.

[0008]

According to the present invention, auxiliary beams are erected above and below an opening formed at a desired position between frame beams of a building, and the lower portion of the upper panel of the opening is formed using the auxiliary beams. In a mechanism for supporting an upper portion of a lower panel, an upper rectangular steel pipe is fixed to an upper auxiliary beam of the opening and a lower rectangular steel pipe is fixed to a lower auxiliary beam, and a substantially L-shaped side surface having a vertical piece and a horizontal piece is provided. The primary side fastener made of engagement hardware,
The vertical piece faces upward on the upper surface of the upper rectangular steel pipe via the horizontal piece, and the vertical piece faces downward on the lower surface of the lower rectangular steel pipe, and is fixed to the lower and lower rectangular steel pipes of the upper rectangular steel pipe. A sash support fitting is fixed to an upper portion, and a secondary lower fastener having an engaging piece formed with an engaging groove at a lower end is attached to a lower inner wall surface of the upper panel of the opening. Is engaged with a vertical piece of a primary fastener on the upper surface of an upper rectangular steel pipe, and a secondary upper fastener having an engagement receptacle formed on an upper end is attached to an upper inner wall surface of the lower panel of the opening. The present invention relates to a wall panel supporting mechanism, wherein a vertical piece of a primary fastener of a lower surface of a lower rectangular steel pipe is inserted into and engaged with a receiving port.

[0009]

A corresponding upper rectangular steel pipe and a lower rectangular steel pipe are fixed to the upper auxiliary beam erected above the opening and the lower auxiliary beam erected below the opening, and the primary fastener is fixed to the square steel pipe. doing. Then, the engaging groove of the secondary lower fastener attached to the lower inner wall surface of the upper panel of the opening is engaged with the vertical piece of the primary fastener of the upper rectangular steel pipe, and also on the upper inner wall surface of the lower panel of the opening. The engagement receptacle of the attached secondary upper fastener is engaged with the vertical piece of the primary fastener of the lower rectangular steel pipe, thereby supporting the lower part of the upper opening panel and the upper part of the lower panel, respectively.

As described above, the upper and lower panels of the opening are locked to the primary fastener via the secondary upper fastener or the secondary lower fastener attached to the inner wall surface, and the panel lower end face or Since the upper end face is not in direct contact with the primary side fastener, even if the skeleton shakes due to an earthquake or the like, the lower end or the upper end of the panel is not rubbed by the primary side fastener, and there is no risk of breakage and missing.

The rigidity of the auxiliary beam is increased by the rectangular steel pipe, and the load on the panel is also distributed to the rectangular steel pipe, so that the supporting strength of the upper and lower panels of the opening is increased.
