BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dry glazing curtain wall which can be easily installed and has excellent watertightness.

[0002]

2. Description of the Related Art In the case of constructing a curtain wall, in addition to the unit system in which each of the standing and blind components is assembled in a factory in advance and brought into a unit to construct the curtain wall, There is a knockdown method in which each component of the eyes is brought to the site as it is, and the curtain wall is constructed by assembling uprights and blinds on the site.

An example of a conventional structure of a dry glazing curtain wall belonging to the latter knockdown system will be described with reference to FIGS. 7 and 8. This is a base 103A, a connecting part 103B extending from the base 103A to the outside of the room, and a projecting part 103 protruding from the connecting part 103B to the panel side.
After the pieces of the upright 103 having C are connected in the vertical direction by joint pins or the like to assemble the upright 103, the cross members are inserted between the adjacent uprights 103, 103 in the side-opening incorporation groove. The seamless eye 101 is incorporated and attached.

More specifically, with respect to the watertightness of the panel P such as glass, the upper part of the panel P is swallowed in the panel fitting groove 101b formed in the upper eyeless portion 101 so that the inner surface between the panel P and the inner surface is closed. Watertightness is achieved by the upper gasket IU, and an outer upper gasket O is provided between the panel P and the outdoor surface.
Use U to make it watertight.

As for the lower part of the panel P, the lower blind 101
The base material 101A is provided on the panel P, and the panel P is placed on the setting block SB arranged on the base material 101A. The interior surface of the panel P is made watertight by the sealing material S having the backup material B as a holding material. The outer surface is watertight by the outer lower gasket OD between the outer surface and the seamless cover 106 locked to the lower seamless member 101.

On the other hand, with respect to both side portions of the panel P, the interior surface of the panel P is separated by a seal material S using the backup material B as a holding material between the inner edge material 104 which is locked and fixed to the upright 103. Watertight, the exterior surface of the panel P is upright 1
The outer vertical gasket OS is watertight between the outer edge-enhancing material 105 and the outer edge-enhancing material 105. Where the cubic 103
In order to form the isobaric space S1 by the overhanging portion 103C and the seamless eye 101, the closing material for the isobaric space S1 and the rubber joint closing material 107 for the seamless cover 106 and the outer edge member 105 are formed. Is prepared.

Here, the reason for providing the outer border material 105 is as follows.
If the outer vertical gasket corresponding to the distance between the inner surface of the overhanging portion 103A of the upright 103 and the outer surface of the panel P is water-tight without being provided, the expected dimension of this outer vertical gasket is This is because the estimated lengths of the upper gasket OU and the outer lower gasket OD are excessively long, and the estimated dimensions of the gaskets are not uniform around the four circumferences of the panel P, and the appearance is deteriorated. Further, it becomes difficult to secure water tightness at the corners of the outer vertical gasket and the outer upper gasket OU and the outer lower gasket OD.

On the other hand, an outer edging material 105 is prepared,
The outer upper edge material 105 is locked to the upright 103, and an outer vertical gasket OS is attached to the outer edge material 105 so that the outer surface of the panel P is watertight. The estimated dimensions of the gasket OU and the outer lower gasket OD and the estimated dimension of the outer vertical gasket OS can be made to coincide with each other, and the design is excellent.

Here, a through hole 101a communicating with the outside of the room is formed in the vicinity of the end of the seamless member 101, and the outer edge member 105 is further provided.
The through hole 105a is formed in the lower portion of the outdoor piece 105A of the main body 1
A through hole 105b is formed at 05B. As a result, the lower horizontal space S1 between the seamless cover 106 and the seamless eye 101, the vertical space S2 surrounded by the overhanging portion 103C and the connecting portion 103B, and the outer edge trim member 105, and the outer edge trim member 10.
5, the vertical space S3 on the indoor side and the panel fitting groove 101
It communicates with the upper horizontal space S4 of b, thereby forming an isobaric space for watertightness.

[0010]

However, as clearly shown in FIG. 8, the outdoor piece portion 105A of the outer edging member 105 comes into contact with the projecting portion 103C by metal touch, and this portion is directly exposed to the outside. Since it is exposed to the surface, there may be a gap in the metal touch part due to the dimensional accuracy of the mold material,
Rainwater that does not want to enter as much as possible may enter from the gap into the isobaric space (directly, the vertical space S2). Further, even if no gap is generated, there is a possibility of intrusion due to a capillary phenomenon.

Furthermore, the path of rainwater intrusion into the vertical space S2 through the above-mentioned metal touch portion and the vertical space S through between the outer edging material 105 and the outer vertical gasket OS.
3 and a path to the vertical space S3 passing between the panel P and the outer vertical gasket OS, and the amount of rainwater intrusion increases accordingly.

Therefore, the main object of the present invention is to form excellent watertightness for a long period of time by elastic contact of two fixed gaskets without forming a metal touch portion, and moreover, it is easy to manufacture the constituent members, Another object of the present invention is to provide a dry glazing curtain wall that can reduce the number of parts and is excellent in workability.

As a function and effect in this case, it is possible to hold the vertical panel holding gasket on the outdoor surface upright,
Although the gasket does not have good adhesion and stable retention to the outdoor surface of the panel, the vertical panel holding gasket is held by an auxiliary material, and this auxiliary material is fixed to the above-mentioned vertical direction That is, the gasket has good adhesion and stable retention. Also,
It is also proposed that the vertical gasket is in elastic contact with the outdoor surface of the auxiliary material. In this case, the effect is that the vertical gasket elastically contacts the outdoor surface of the auxiliary material, so that the positional stability of the vertical gasket is secured, and the watertight effect between the auxiliary material and the vertical gasket is ensured. Is to be higher. Further, a mode is proposed in which the auxiliary material also supports the indoor side surface of the panel. In this case, the effect is that the number of members can be reduced by supporting the interior side surface of the panel with an auxiliary material that holds the vertical panel holding gasket. Further, an opening that communicates with the outside air is formed at the lower side of the adjacent blind side, and a lower horizontal side lower space that faces the panel and the panel holding gaskets arranged on the four circumferences of the inner and outer surfaces is provided. There is also proposed a mode in which both vertical spaces of (1) and the upper horizontal space between the upper seamless space are communicated with each other to make each space an isobaric space. The effect of this case is that it is possible to prevent rainwater from entering the indoor side by forming an equal pressure space.
