Description

[Detailed explanation of the invention] This invention communicates the mullions with the glass pockets, which are formed in a blank manner, and connects each of the above glass pockets to the outside air through the blank openings, so that the inside of the glass pockets can be connected to the outside air and pressure. The present invention relates to a curtain wall that securely shuts off rain by forming an equal pressure layer with a small difference.

For example, Japanese Patent Publication No. 54-27649 is known as a curtain wall constructed by combining mullions and blinds, and communicating the glass pockets of the mullions and blinds with the outside air to shut off rain. ing.

However, this conventional invention has various drawbacks because each mullion and the open glass pocket are provided with an opening that communicates directly with the outside air.

For example, if there are many openings, the strength of a mullion or a mullion will decrease, so the wall must be thicker or the cross-sectional structure must be complicated, and mullions in particular require sufficient strength because they run vertically. However, many openings are formed to create an unreasonable structure.

The present invention was devised in view of the above, and by opening holes only in the open area, not only the open glass pocket but also the mullion glass pocket can be made to have the same pressure with the outside air. The rainwater that seeps in through the gap between the roof and the roof is drained away by its own weight.

The extending ridge support piece 23 constitutes a step-like outdoor surface, and the lower surface of the ridge support piece 23 has a first vertical surface 2.
It has a second vertical surface 21 located on the outside of the room.

In the second blind 7 formed as described above, the first rib 25 fixed to the rib support piece 23 has an L-shaped cross section like the rib 16, and has a second vertical surface 21 at the lower end.
An attachment piece 26 is vertically attached to the outdoor surface of the vehicle, and a through hole 26' is formed in the attachment piece 26 to correspond to the through hole 21'.

Further, a second ridge 27 is attached to the second blind 7 to support the upper edge of the plate to be inserted below. This second
The rib 27 is hollow and is inserted and supported on the lower surface of the main hollow portion 18, and works together with the glass pocket component 24 to support the upper edge of a plate material such as glass, metal, or synthetic resin.

In order to construct a curtain wall with the mullions 1, the first mullions 6 and the second mullions 7 formed as described above, the mullions 1 are fixed to the frame so that they are arranged in parallel, and the The first blinds 6 and the second blinds 7, each of which has only the respective ends of the hollow parts 8, 18 and the outside air passage hollow parts 11, 22 closed with a lid material, are alternately hung horizontally between the mullions. The end of the eye is inserted halfway into the opening 5 of the mullion, and is fixed with an angle-shaped metal fitting c while being crimped to the indoor side.

Next, a plate material a made of glass, metal, synthetic resin, etc. is fitted from the indoor side or the outdoor side into the rectangular space surrounded by the left and right mullions 1, 1, the first mullion 6 and the second mullion 7, A hollow rim 2 for mullion 1 has upper and lower ends closed with rubber or the like on the indoor side of side opening 5 of mullion 1.
8, and sandwiching sealing materials b, b between the outdoor surface of the ridge 28 and the indoor side edge of plate material a, and between the indoor surface of the semi-hollow part 3 and the outdoor side edge of plate material a, respectively. , firmly supports the side edges of plate material a. Therefore, a glass pocket 29 is formed on the side surface of the mullion 1, which is surrounded by the indoor surface of the semi-hollow part 3, the outdoor outer surface of the main hollow part 2, the ridge 28, and the sealing materials b, b. .

On the other hand, in the first blind 6, the ridge 16 is fixed to the ridge support piece 15, and the attachment piece 17 is attached to the second vertical surface 1.
Attach it to 4 and secure it with screws, etc. Then, the lower end edge of the plate material a located above the first mesh 6 is positioned between the sealing material attachment piece 9 and the ridge 16, and the attachment piece 9
Seal materials b, b are sandwiched between the tip and the lower end interior surface of the plate material a, and between the upper end interior surface of the ridge 16 and the lower end interior surface of the plate material a, to firmly support the lower end of the plate material a. Therefore, the main hollow part 8 is located on the upper surface of the first mesh 6.
An upper glass pocket 30 is configured, which is surrounded by the outer surface of the upper chamber, the first vertical surface 13 of the hollow part 11 for passing outside air, the ribbed edge 16, the sealing materials b, b, etc. Since it is not closed with a lid material, it communicates with the glass pocket 29 of the mullion 1 described above. The second vertical surface 14 faces outdoors.

In addition, the first mesh 6 receives the upper edge of the plate material a attached to the lower side into the lower glass pocket 12, and
The upper edge of is firmly supported by sealing materials b and b. Since the left and right ends of this lower glass pocket 12 are not closed with lid materials, the glass pocket 29 of the mullion 1
communicate with.

On the other hand, in the second mesh 7, the upper edge of the plate material a located on the lower side, that is, the upper edge of the plate material a that supported the lower edge of the first mesh 6, is fitted between the glass pocket component piece 24 and the second rib 27. the upper edge of the plate material a with a sealing material b,
Support firmly with b.

Therefore, a second rib 27 is provided on the lower surface of the second mesh 7.
A lower glass pocket 31 is constituted by being surrounded by the outdoor surface of the glass pocket, the glass pocket constituent piece 24, and each sealing material b, b. Furthermore, the second blind 7 is a plate member a attached to the upper side, that is, the lower glass pocket 12 of the first blind.
The lower edge of the plate material a supporting the upper edge is fitted between the first ridge 25 and the sealing material attachment piece 19, and the lower edge of the plate material a is supported by the sealing materials b. This allows the second
On the top surface of the blind 7, there is a mounting piece 19, an upper chamber outer surface of the main hollow section 18, and a first vertical surface 2 of the outside air passage hollow section 22.
0, an upper glass pocket 32 surrounded by the first rib 25 and the sealing materials b, b, etc. is constructed. The aforementioned lower glass pocket 31 and the aforementioned upper glass pocket 32 communicate with the aforementioned glass pocket 29 of the mullion 1 since their respective left and right ends are not closed with lids. Further, the second vertical surface 21 faces outdoors.

Therefore, each open glass pocket and the mullioned glass pocket form a communicating space.

Furthermore, the upper glass pocket 30 of the first opening 6 communicates with the outside of the room through the hollow part 11 for passing outside air through the through holes 17', 14', and 13', and
The upper glass pocket 32 communicates with the outdoor side through the hollow part 22 for passing outside air through the through holes 26', 21' and 20'. Therefore, in the communication space described above, since the open upper glass pocket opens to the outside air, the entire area of the communication space becomes an equal pressure layer with almost no pressure difference with the outside air.

In such a configuration, rainwater enters the glass pocket by capillary action from the minute gap between the plate material and the sealing material, the minute gap between the sealing material and the ridged edge, or the minute gap at the connection between the mullion and the mullion. When you get into it,
Since each glass pocket forms an equal pressure layer with the outside air, the rainwater that seeps into the pocket flows down due to its own weight, and is eventually led to the open glass pocket, where it drips to the outside from the hollow space for the outside air to pass through.

Therefore, rainwater is reliably sealed and rainwater does not seep into the interior of the room.

In the above explanation, the case where two types of blinds are alternately installed horizontally in mullions is taken into consideration, but this is done in consideration of the ease of installing the board materials in the field work. Therefore, it is possible to implement the invention in any way, even if only one of the eyes is closed, or even if it is a blind of another structure, as long as the structure is not changed within the scope of the utility model registration claim. Also, in each of the holes 6 and 7, the through holes 14' and 13' or the through holes 2
If the lateral positions of 1' and 20' are changed, even if rainwater blows into the outside air passage hollow part 11 or 22 from the ventilation hole 14' or 21' due to wind, it will not blow into the glass pockets 30, 32. . Therefore, much rainwater does not accumulate in each glass pocket.

As is clear from the above, according to the present invention, an upper glass pocket that opens upward is provided on the upper side of the outdoor side of the main hollow part, and a lower glass pocket that opens downward is provided on the lower side of the outdoor side of the main hollow part. established,
A hollow part for passing outside air is formed on the indoor side of the upper glass pocket, which is installed horizontally between the mullions with no holes, so that the glass pockets of the mullions and the open spaces are connected, and the glass pockets with no holes are for passing outside air. A hole is formed in a first vertical surface that partitions the hollow portion from the hollow portion, and a second vertical surface that is provided below the first vertical surface and constitutes the outdoor side of the hollow portion for passing outside air. The mullion-shaped glass pocket is made to communicate with the outside air by allowing the pocket to communicate with the outside air.

Therefore, the glass pockets communicate with the outside air through the open glass pockets without having to open any ventilation holes in the mullion for introducing outside air, so even if rainwater seeps into the glass pockets of the mullion, it will be drained out by its own weight. Since the mullions do not require opening holes after extrusion molding, they are extremely easy to manufacture, and because they can be made thin, they are significantly effective in terms of cost and assembly work.

In addition, the open hollow part for passing outside air is located on the indoor side of the upper glass pocket and has a hole between the first vertical surface and the second vertical surface located on the outside of the room from the first vertical surface, allowing outside air to pass through. Since it communicates with the upper glass pocket through the hollow part, even if rainwater blows into the hollow part for passing outside air through the hole in the second vertical surface due to wind,
Raindrops hit the inner surface of the outside air passage hollow and flow out from the through hole in the second vertical surface, but do not flow into the upper glass pocket. Therefore, the connection area between the mullion and the mullion is extremely well protected from rain, and rainwater can be reliably prevented from seeping into the interior of the room.
