DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curtain wall, and more particularly, to a panel formed of a panel as a vertical bar and a blind as a horizontal bar, in which a panel plate such as a decorative plate or a glass plate is provided. Related to an attached curtain wall.

[0002]

2. Description of the Related Art As shown in FIG. 10, a curtain wall provided on a wall surface of a building such as a building has a frame formed by a cubic 100 as a vertical beam and a blind 120 as a horizontal beam. A panel plate 140 such as a glass plate 140a or a decorative plate 140b is attached. The cubic 100 and the blinds 120 that form such a curtain wall are often made of aluminum, which does not easily generate rust or the like even when exposed to wind and rain, and the back side of the aluminum cubic 100 is also exposed indoors. ing. However, metal such as aluminum is a good conductor of heat, and heat is easily transferred to the outside of the room via metal parts such as the aluminum square 100. For this reason, in the winter season, the cubic and the like are cooled, dew condensation is likely to occur on the exposed portion exposed to the indoor side of the cubic, and there is much waste of air conditioning costs such as heating costs. Also, in recent years, attempts have been made to add warmth to the interior by using wood grain or the like for interiors such as indoor walls and furniture, but the back side of the aluminum cubicle 100 is exposed to the interior. However, even if wood or the like is used as much as possible in the interior of the room, the coldness of the aluminum product is present in the room, giving a sense of incongruity.

In order to solve the problems of the conventional aluminum cubicle 100, as shown in FIG. 11, a wooden cubicle (hereinafter referred to as a wooden cubicle) 20 is used.
It can be considered to be 0. The wooden ridge 200 of FIG. 11 is fixed to the wooden ridge 200 with a wood screw 202, and is made of an aluminum outer edge member 20 that is unlikely to generate rust or the like even when exposed to wind and rain.
4, a composite glass plate 206 is attached.
Further, a gap between the composite glass plate 206 and the wooden framing 200 and the outer ridge member 204 and a head portion of the wood screw 202 are filled with a sealing member 208 such as silicone to prevent rain or the like from entering. Note that the gap between the composite glass plate 206 and the wooden framing 200 and the outer ridge member 204 is filled with a cushioning member 210 inside the seal member 208.

[0004]

According to the curtain wall using the wooden framing 200 shown in FIG. 10, the portion of the wooden framing 200 exposed in the room is made of wood having a lower thermal conductivity than metal. Even in winter, dew condensation hardly occurs on the exposed parts exposed to the interior of the cubicle, and waste of air conditioning costs such as heating costs can be reduced as much as possible. In addition, even in a room in which wood or the like is used as much as possible in the interior of the room, it is possible to prevent a sense of incongruity as in the case of the conventional aluminum cubicle. However, due to the difference in the thermal expansion coefficient between wood and metal such as aluminum, the composite glass plate 206 or There is a possibility that the metal fittings may be damaged. Further, heat is easily transferred to the outside of the room through a metal attachment such as an aluminum outer ridge member 204 and the gap between the composite glass plate 206 and the wooden framing 200 and the outer ridge member 204 by a seal member 208 and the like. It is very difficult to keep moisture from entering the seal space 212 even if the is sealed. For this reason, in winter etc.
The metal fixture is cooled and the metal fixture and wooden
There is a possibility that dew condensation may occur on the contact surface with the zero and corrode the wooden room 200. In this way, by using a wooden cubicle for the curtain wall, the composite glass plate 206 can be used.
And the wooden mount 200 cannot be used at all because the wooden mount 200 may be corroded due to breakage of the metal mount or the metal mount and dew condensation generated on the metal mount.

A resin cubic is used in place of the wooden cubicle 200, and a sheet material having a grain pattern is adhered to the surface of the resin cubic.
00 can be prevented from being corroded. However, even when the resin-made cubic is adopted, the composite glass plate 206 is not formed due to the difference in thermal expansion between the resin-made cubic and the metal fixture due to the difference in the thermal expansion coefficient between the resin and the metal such as aluminum. And the possibility of damage to metal fittings still exists. In addition, since dew condensation occurs on the contact surface between the metal fitting and the resin cubicle, it is necessary to consider measures for treating the dew condensation that has occurred. However, at present, attempts are being made to incorporate the warmth of wood into a room, and at present, a wooden or resin cubicle that can provide the warmth of wood is used for the curtain wall exposed in the room. Is strongly requested. Therefore, an object of the present invention is to provide a heat-insulating cubic formed of wood and / or resin having a lower thermal conductivity than metal, and a thermal expansion / contraction difference with a metal fitting such as aluminum for mounting a panel plate. Another object of the present invention is to provide a curtain wall capable of eliminating condensation and the like.
