[0002]

2. Description of the Related Art It is widely practiced to cover most of an outer wall of a building with a glass panel from the viewpoint of a design for adjusting the appearance of the building. FIG. 10 is a partial front view of an outer wall of a conventional building made from such a viewpoint, and FIGS. 11 to 14 show specific structures of the conventional outer wall, respectively. Such an outer wall is constituted by assembling a plurality of curtain walls 2 and 2 (see FIG. 2 showing an embodiment of the present invention) on an assembled steel frame (frame) 1. Each of the curtain walls 2, 2 is constructed by assembling one or both of the fixed windows 3, 3a and the movable window 4 to a holding frame made of iron or an aluminum alloy, respectively. ing. The holding frame constituting each curtain wall 2 is replaced with the steel frame 1.
Fixed window 3, 3a and movable window 4
However, as shown in FIG.

Further, a structure relating to a decorative sash for preventing the appearance of a building from becoming inorganic due to the extruded cubic members made of an aluminum alloy being exposed on the outer wall surface is also disclosed in, for example, Japanese Patent Application Laid-Open No. Hei 3-107043. As described in the gazette, it is conventionally known. FIGS. 11 to 14
The structure in which the fixed windows 3 and 3a and the movable window 4 are constituted by such a makeup sash is shown. Each of such decorative sashes is composed of a main frame made of an extruded material made of an aluminum alloy and a cover frame made of a non-metallic material, and the periphery of the glass panels 5, 5 is provided between the main frame and the cover frame. The part is pinched and fixed.

The cubic 6 and the blinds 7, 7 are each made of an extruded material made of an aluminum alloy. However, if these members 6, 7 are exposed to the outdoor side as they are, the appearance of the building is assumed to be inorganic. Become. For this reason, conventionally, as shown in FIGS. 11 to 14, a part of each of the above members that is exposed on the outer wall surface of the building is covered with a synthetic resin cover frame 8.
There is known a makeup sash covered by a cover. Such a cosmetic sash is described in, for example, Japanese Patent Application Laid-Open No. Hei 3-107043.

[0005] In the center of the outdoor side surface of the screen 6 and the blind 7 constituting the fixed window 3 with such a decorative sash, the length direction of each of these members 6 and 7 (front and back directions in FIGS. 11 to 12). , Three ridges 9 and 10 are formed.
And, between the adjacent ridges 9 and 10, the locking groove 1
1, and 11. On the other hand, on the indoor side surfaces of the cover frames 8, 8, locking ridges 12, 12 having shapes and sizes that can be pushed into the locking grooves 11, 11 are formed. The cross-sectional shapes of the outer surfaces of the locking ridges 12, 12 and the inner surfaces of the locking grooves 11, 11 are ratchet-toothed waveforms that can be engaged with each other. Therefore, the locking ridges 12, 12 can be pushed into the locking grooves 11, 11 while elastically deforming the ridges 9, 10. After the push-in, the engagement of the corrugations prevents the locking projections 12 from coming out of the locking grooves 11.

When the peripheral edge of the glass panel 5 is to be locked, a portion of the glass panel 5 near the outer periphery of the indoor side surface is brought into contact with the packings 13 and 13 which are locked to the members 6 and 7, respectively. The locking ridges 12, 12 are engaged with the locking grooves 11,

[0010]

However, in the case of the conventional structure configured as described above, there are the following points to be solved.

[0011] The finding of the continuous portion between the adjacent fixed windows 3, 3 is different from the finding of the continuous portion between the adjacent movable window 4 and the fixed windows 3a, 3a, and the design of the outer wall surface is deteriorated. That is, the continuous portion between the adjacent fixed windows 3, 3 is shown in FIGS.
As shown in FIG. 2, while adjacent cover frames 8 are in contact with each other, adjacent movable windows 4 and fixed windows 3a, 3a
13 and 14, gaps 17, 17 are present between adjacent cover frames 8a, 8b, as shown in FIGS.
As a result, the design of the movable window 4 installation portion is different from the design of the other portions, and the design of the outer wall surface of the building cannot be unified, thereby deteriorating the appearance of the building.

A drainage structure for discharging rainwater that has entered the inside of the fixed window is complicated. That is, the front edges of the synthetic resin cover frames 8, 8 are in elastic contact with the outdoor side surface of the glass panel 5, but are not sealed with an adhesive or the like. Therefore, when wind is blown toward the outer wall surface during rainfall, it is inevitable that rainwater enters the spaces 18 inside the cover frame 8. In this way, space 18, 18
Rainwater that has entered inside must be discharged outside,
As shown in FIGS. 11 to 12, when the cover frames 8, 8 forming the adjacent fixed windows 3, 3 are in contact with each other, the space between the adjacent fixed windows 3, 3 in the space 18, 18 is reduced. Cannot discharge rainwater.

The outer wall of the building of the present invention has been invented to solve any of the above-mentioned disadvantages.

To support and fix the edges of each of these panels.
In addition, there is a gap having substantially the same width between the cover frames forming adjacent panel units.

[0015]

In the case of the outer wall of the building of the present invention constructed as described above, a gap having substantially the same width between the cover frames forming adjacent panel units, regardless of whether the window is fixed or movable. , It is possible to unify the design between the part where only the fixed window is installed and the part where the movable window is installed. In addition, since the rainwater that has entered the space inside the cover frame can be immediately discharged outside through the gap, the structure of the rainwater drainage facility can be simplified.
