Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a curtain wall.

[0002]

2. Description of the Related Art A mullion type curtain wall has hitherto been proposed as a wall surface structure for preventing the sway and the like of the building body from being transmitted to the wall surface. This curtain wall is configured by arranging a member called a mullion between the upper and lower floors or beams so as to be movable relative to the skeleton side, and fixing a wall forming member such as glass or a spandrel panel to the mullion. .

[0003]

However, in the above-mentioned conventional example, the mullion is formed as a constituent member which moves relative to the building skeleton, and when swaying or the like occurs in the building skeleton, the mullion and the wall constituent member. Since the and are moved together with respect to the building skeleton, it is necessary for the floor skeleton and the like of each floor to bear the own weight of the mullion and the wall component members.

As a result, there is a problem that it cannot be applied to, for example, a wooden house, a steel frame, or a structure having a lower load bearing capacity of a skeleton than a reinforced concrete structure.

Further, when the wall forming member, especially the sash is formed of wood, the connecting portion between the mullion and the sash moves as a unit, so loosening of wood screws or the like is likely to occur, and the sash is connected to the mullion. There is a problem of low reliability.

The present invention has been made to solve the above-mentioned drawbacks, and an object of the present invention is to provide a curtain wall applicable to wooden construction and the like.

[0007]

According to the present invention, the above object is to provide a mullion 4 whose upper and lower ends are fixed to a ceiling body 1 and a foundation 2 and are erected at predetermined intervals independently of a floor body 3 of each floor.
And a plurality of unit wall structures 5, which are vertically hung so that both side portions are movably suspended upward from the adjacent mullion 4,
This is accomplished by providing a curtain wall having 5, ...

In the present invention, the unit wall structure 5 constituting the wall surface is suspended and supported by the mullion 4 whose both ends are fixed to the ceiling body 1 and the foundation 2. By fixing the mullion 4 to the skeleton and the foundation 2 side, the unit wall structure 5 is hung on the ceiling skeleton 1 through the mullion 4, and the weight of each unit wall structure 5 is the mullion 4 and the ceiling skeleton. It is distributed to the holding power by 1.

As a result, the stress load on the skeleton side, especially on the floor skeleton 3 on each floor is eliminated, so that it is possible to construct a curtain wall for a wooden building.

Further, since the unit wall structure 5 is independently movable as the unit wall structure 5 with respect to the mullion 4, no stress load is applied to the unit wall structure 5. As a result, even when a wooden sash or the like is used for the unit wall structure 5, loosening of the wood screw due to repeated stress does not occur.

Although the mullion 4 can be formed by using an appropriate material, the outdoor side end face 6a of the wooden main body 6 is formed.
It is desirable that the T-shaped channel material 7 is fixed to and formed. The wooden main body 6 can be rigidly joined and behaves as a mechanically integrated member in the joined state. Therefore, when constructing a relatively high-rise building, the marion 4 is appropriately joined to form a long-sized one. Can be easily obtained.

Further, the mullion 4 is made into a composite of the wooden main body 6 and the T-shaped channel material 7, and the channel material 7
The unit wall structure 5 through the headed pin member 8 fixed to the
By supporting the above, it is possible to secure sufficient strength against a concentrated stress load in the movable connecting portion with the unit wall structure 5. The pin member 8 may be a headless member by adjusting the length with respect to the object to be locked.

It is not necessary for the unit wall structure 5 to be detachable from the mullion 4 after construction as long as it can move relative to the mullion 4, but each unit wall structure 5 can also be detached from the mullion 4 after construction. By making it detachable from 4, it is possible to exchange and remove any unit wall structure 5.
Maintainability is improved.

In this case, the unit wall structure 5 is connected to the mullion 4 by engaging the engaging hole 10 of the connecting plate 9 fixed to the side wall with the pin member 8 and the engaging hole 10
Can be a curtain wall that is open to the side of the connecting plate 9 and can be attached to and detached from the pin member 8.

Further, when the rising portion 10a which is inclined with respect to the vertical line is formed in the locking hole 10, the relative movement of each unit wall structure 5 with respect to the mullion 4 in the vertical direction is performed outside or inside the building ( It may include a movement in the indoor direction). As a result, it is possible to apply a horizontal component force to the unit wall structures 5 by utilizing the force of each unit wall structure 5 moving downward due to its own weight. It is possible to secure the seal pressure used and improve the wall sealing performance.

An inverted L-shaped locking hole 10 having a rising portion 10a extending obliquely upward from b is formed. As will be described later, after the unit wall structure 5 is relatively displaced with respect to the mullion 4, when the unit wall structure 5 descends due to its own weight, the unit wall structure 5
5A, the locking hole 10 is formed so as to gradually incline in a direction away from the open side of the guide cutout 10b as it goes upward, so that a component force is generated in the outdoor direction. To be done.

On the other hand, the inner peripheral wall surface of the frame body 18 is provided with a supporting step portion 23 on the entire circumference thereof, and as shown in FIG.
The board 3 arranged in the frame body 18, or a surface member 25 such as glass is fixed by 3 and the pressing member 24 fixed to the front surface of the frame body 18. Further, the lower frame member 18b of the frame body 18 is formed by an inclined surface which becomes lower toward the front, so that rainwater and the like can be promptly discharged to the outdoor side.

Therefore, in this embodiment, first, both ends are fixed to the mullion fixing metal fittings 14 and 14 fixed to the ceiling body 1 and the foundation 2 of the building, and the mullion 4 is erected, and between the mullion 4 and 4. A wall surface is formed by connecting the unit wall structures 5 formed in advance to. As shown in FIGS. 6 and 7, the unit wall structure 5 is connected to the mullion 4 by inserting the fastener plate 9 into the pin member 8 projecting from the metal channel member 7 through the guide notch 10b. Be seen. Prior to the work of mounting the unit wall structure 5, a backup material 27 is arranged on the surface of the mounting piece 7a of the metal channel material 7, and a sealing material is further provided on the tip of the front protruding piece 7b of the metal channel material 7. 28 is attached.

The frame 18 of the adjacent unit wall structures 5
The front protruding piece 7 of the metal channel material 7 at each tip.
Since the jack bolts 29 that are abutted against the side wall of b are mounted to regulate the arrangement posture of the unit wall structures 5 between the mullions 4 and 4, the connection between the unit wall structures 5 and 5 is
In addition to the horizontal posture shown in FIG. 6 (a), it is possible to make an angle as shown in FIG. 6 (b). In this case, the pin member 8 is fixed at a predetermined angle with respect to the front protruding piece 7b. Furthermore, adjacent unit wall structures 5, 5
After the sealing material 28 'is interposed between the frame bodies 18,
The opposite end of the joint block 30 fixed to either one of the joint blocks is covered with the other end to secure the seal of the side connecting portion.

As described above, the unit wall structures 5 arranged between the mullions 4 and 4 are sequentially connected so as to be stacked above the foundation 2. As shown in FIG. 7, the upper unit wall structure 5 is attached with the lower frame member 18b supported on the dead weight receiving flange 31 fixed to the metal channel member 7 of the mullion 4, and the upper unit wall structure 5 is attached. A spacer 33 is arranged between the lower frame member 18b of the unit structure 5 and the upper frame member 18c of the lower unit wall structure 5. Also, the spacer 3
3 indoor end side upper surface 33a and the self-weight receiving flange 31
A space 34 for moving the unit wall structure 5 upward is secured between the lower surface and the lower surface, as shown in FIGS. 3 and 7.

A seal member 28 "is interposed between the spacer 33 and the lower frame member 18b and the upper frame member 18c of the upper and lower frame members 18, and the upper frame member 18c of the lower frame member 18 is provided.
The joint material 35 fixed to the above covers the spacer 33 and the lower frame member 18b of the unit wall structure 5 on the upper stage side, and the seal of the connecting portion is secured.

In the curtain wall constructed as above, when the building body side is shaken by an earthquake or the like,
The unit wall structure 5 having the moving space 34 above and connected to the mullion 4 by the locking hole 10 can move relative to the building frame and the mullion 4.

As shown in FIGS. 5A and 7, when the mullion 4 moves upward due to an earthquake, the unit wall structure 5 moves upward together with the mullion 4 only at the initial stage of vibration, and then the mullion 4 moves. When moving downward, the movement space 34 and the locking hole 10 do not follow the movement.

In this state, the unit wall structure 5 located above the initial position gradually moves downward due to its own weight W shown in FIG. 5 (a), but thereafter it also moves vertically. Since the member 8) is connected by the rising portion 10a of the locking hole 10, it does not follow the movement thereof.

That is, for example, the upward force F shown in FIG. 5 (a) accompanying the upward movement of the pin member 8 is divided into a force A in the direction along the rising portion 10a and a force B orthogonal thereto. And acts on the unit wall structure 5, the unit wall structure 5
For, only force A actually works. And force A
Acts because the pin member 8 moves within the rising portion 10a, and as a result, the unit wall structure 5 does not move upward.

A unit wall structure 5 in which two fastener plates 9 each having a rising portion 10a are arranged on both sides
The pin member 8 moves upward along the rising portion 10a inclined at the angle θ, so that the pin member 8 slightly moves rearward (indoor direction) with respect to the mullion 4.

After that, when the earthquake stops, the unit wall structure 5 moves relative to the mullion 4 downward and forward (outdoor direction) along the rising wall 10a by its own weight w, and initially, It can be automatically returned to the position.

Therefore, even if the mullion 4 sways due to an earthquake or the like, the unit wall structure 5 moves relative to the mullion 4, so that no stress is applied to the unit wall structure 5.

In this embodiment, FIG.
As shown in (a), the rising portion 10a of the locking hole 10
Is formed so as to be inclined at an angle θ in a direction away from the open side of the guide cutout 10b, but is inclined at an angle θ ′ in the direction approaching the open side of the guide cutout 10b as shown in FIG. 5B. In such a case, a component force in the indoor direction can be generated at the time of returning to the unit wall structure 5.

Further, although the application to the relatively low-rise building has been described above, the application to the higher-rise building is also possible, and in this case, the mullion 4 is joined vertically in the wooden main body portion 6. used. Further, in the case of high-rise building, in order to keep the distance between the mullion 4 and the building skeleton constant, the mullion 4 can be connected to the floor skeleton 3 of each floor. A connection structure is adopted in which only the movement in the separating direction is restricted with respect to the frame 3 and no load is applied.

Furthermore, in the present embodiment, the curtain wall is formed by connecting a plurality of fixed unit wall structures 5, but if the curtain wall is movable relative to the mullion 4, the unit walls having different shapes are formed. It is also possible to combine the structures 5 ′, 5 ″ and the like.
