Description

[Detailed description of the invention] This invention relates to a mullion-shaped rain-blocking structure in a curtain wall, and its purpose is to prevent raindrops, etc. from entering the room from outside by utilizing the principle of equal pressure. .

That is, the gist of this invention is to provide a recess on the outer surface of the mullion, provide a raindrop prevention wall on the opening side of the recess to narrow the opening of the recess,
A vertical space is formed between the mullion and a panel attached to the mullion, and a communication port is formed adjacent to the back surface of the raindrop prevention wall to communicate the vertical space with the recess, and A buttful material is installed inside the mouth, and by communicating the inside of the vertical space with the outside air through a recess, the inside of this vertical space is made equal to the outside air pressure, and rain is shut off based on the principle of equal pressure. In addition, it is an object of the present invention to provide a mullion-shaped rain blocking structure for a curtain wall, which is characterized in that raindrops and the like trying to enter a vertical space can be blocked by a raindrop blocking wall and a baffle material.

Examples of this invention will be described below based on the drawings.

The drawing shows mullions 1 and mumu 2 assembled in a grid pattern.
This shows a curtain wall structure in which a panel such as a fitting part 3 and a projecting window 4 is arbitrarily formed in each frame part formed by the above.

The mullion 1 has a recess 5 formed along the longitudinal direction of the mullion 1 on its outer surface, that is, the outdoor side surface thereof, and an opening 5' of the recess 5 is narrowed on the opening side of the recess 5. Raindrop blocking walls 6, 6 are formed.

On the other hand, the panel attached to the mullion 1, that is, the fitting part 3 and the protruding window 4, are spaced between the mullion 1 and the vertical space 7 along the recess 5, as shown in FIGS. 3 and 4, respectively. It is attached to form a In this case, the fitting part 3 is
As shown in FIG. 3, it is attached to the mullion 1 with a ridge 8 that engages with the mullion 1 and a buttful member 9, which will be described later, to form a vertical space 7 between the mullion 1 and the mullion 1. As shown in FIG. 4, the projecting window 4 is constructed by attaching a window frame 4c to a mullion 1, which supports a frame 4b in which a glass 4a is fitted in such a way that it can be opened and closed. A vertical space 7 is formed in the vertical space 7. Incidentally, when the projecting window 4 is closed, the vertical spaces 7 are formed in the same manner as described above by the sealing materials 4d and 4e attached to the window frame 4c. The vertical spaces 7 formed in this manner communicate with the inside of the recess 5 through a communication port 10 formed on the inner surface of the recess 5 of the mullion 1 close to the back surface of the raindrop prevention wall 6. At the same time, it is communicated with the outside of the room so that the pressure is maintained at the same pressure as the outside air.

Reference numeral 9 denotes a baffle material, which allows raindrops to fall near the communication port 10 even if there are raindrops that enter from the communication port 10 on the wind blowing diagonally to the curtain wall. In this example, the baffle member 9 is disposed over a continuous space like the rim, so that a communication port a is formed so that the external pressure can be guided further inward. Further, b is also a communication port. Furthermore, in FIG. 4, 9' is the window frame 4c.
, and c is a communication gap.

In addition, the blind part 2, the fitting part 3, and the protruding window 4
As shown in FIGS. 5 and 6, a horizontal space 11 communicating with the vertical space 7 is formed at the attachment portion of these attachment portions, that is, the lower end of the fitting portion 3. Drain holes 12 are provided between the opening 2 and between the projecting window 4 and the opening 2, respectively.
The lateral space 11 is communicated with the outside through the . In addition, in FIG. 5, 13 is a glass mounting piece,
14 is installed in the drain hole 12 so that rainwater flows into the horizontal space 1
It is a thick piece that prevents it from entering the inside of 1.

In addition, a batten 16 as shown in FIG. 2 is attached to the recess 5 side of the joint of the mullion 1, and this batten 16 maintains the air-water tightness of the joint of the mullion 1. There is. A space 17 is formed between this batten 16 and the mullion 1, and this space 17 is communicated with the inside of the recess 5 through a communication port 18 provided at the lower end of the batten 16, so that outside air can enter the space 17. The space 17 is maintained at a pressure equal to that of the space 17, and also communicates with the vertical space 7. Note that 15 is a closing member that closes the space between the upper end of the batten 16 and the mullion 1.

The rain cover structure of this invention constructed as described above is provided with a recess 5 on the outer surface of the mullion 1 along the longitudinal direction of the mullion 1,
There is a vertical space 7 along the recess 5 between the fitting part 3 attached to the panel or the panel such as the projecting window 4.
At the same time, a part of this vertical space 7 is communicated with the inside of the recess 5 through the communication port 10, so that the pressure inside the vertical space is equal to the pressure of the outside air.
Watertightness between the mullion 1 and the panel can be improved by the equal pressure principle. Moreover, since the communication port 10 opens close to the back surface of the raindrop prevention wall 6, it is possible to substantially prevent raindrops from entering due to airflow having kinetic energy other than pressure difference. It is something. According to this invention, a raindrop blocking wall is formed by forming a recess in the mullion and narrowing the opening, so this mullion not only has the effect of blocking rain using the equal pressure principle, but also can be used as a curtain wall. It also functions as a rail for gondola wheels used for cleaning, etc. That is, the seventh
As shown in Fig. 8, the wheels of the gondola consist of a wheel A that prevents swinging in the indoor and outdoor directions, and a wheel opening that restricts swinging in the left and right directions, and is fixed to the gondola by a connecting rod. There is. As a result, the side walls 2 and 2 of the recess serve as guides for the wheel opening, and the raindrop prevention wall 6 and the bottom wall 6 serve as guides for the wheel A. As mentioned above, the raindrop prevention wall 6 not only prevents raindrops from entering the communication port 10, but also serves as a guide to restrict the movement of the gondola wheels toward the outside, so its utility value is significant.

In addition, although the above example describes a curtain wall structure in which a fitting part and a projecting window are assembled, the structure is not necessarily limited to this type of structure, and can be applied to all curtain wall structures in which arbitrary panels are attached. It can also be applied to
