Description

[Detailed description of the invention] This invention relates to a curtain wall rain protection structure that is formed by vertically connecting a waist panel and a window panel formed of, for example, a PC board.

In other words, the gist of this invention is to make the horizontal space formed between the panels equal to the outside pressure through the openings, to prevent rainwater from entering through the openings, and to drain it to the outside. An object of the present invention is to provide a curtain wall rain cover structure characterized in that it is equipped with a drainage board to safely equalize the pressure in the horizontal space and perform good rain cover based on the principle of equal pressure. That is.

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

In the figure, 1 is a waist panel formed from a PC version, etc., 2
is the glass fitting groove 2b of the aluminum rectangular frame 2a
It is a window panel in which a glass 2d is attached with a sealing material 2c interposed therein, and the waist panel 1 and the window panel 2 are connected to each other in the vertical direction as shown in FIGS. 1 and 2, and , similar types are connected to each other in the left and right direction, and a vertical space 3a and a horizontal space 3 that communicate with each other are formed around the four circumferences of each waist panel 1 and window panel 2, as is clear from FIGS. 4 and 5. ing. However, there are 2 window panels at the top.
However, if the waist panel 1 is located at the bottom,
The horizontal space formed by the window panel 2 and the waist panel 1 and the vertical space formed between the waist panels do not communicate with each other. In this case, waist panel 1 and window panel 2
At the joint part with these two panels 1,
A horizontal space 3 is formed between the panels 1 and 2, and a sealing material is interposed between the indoor sides of both panels 1 and 2 to separate them from the indoor side. An adjustment plate 6 made of an extruded aluminum member having a substantially L shape and forming an L-shaped passage between the adjustment plate 6 and the waist panel 1 is disposed via a shaped bracket 5. A slit-shaped opening 7 is formed between them. This adjustment plate 6 has an inclined piece 6b that stands up on one end of the horizontal base 6a, that is, on the indoor side, facing the lower step 1a of the waist panel 1 and connects with the bracket 5. When arranged, outside air passing through the slit opening 7 is bypassed and introduced into the horizontal space 3. Also, outside air inlet 12
At the entrance, outside air is also introduced into the vertical space formed between the waist panels. Furthermore, a draining plate 8 is attached to the lower surface of the waist panel 1 in the horizontal space 3, and has an inclination blocking piece 8a that faces the inclined piece 6b of the adjustment plate 6 and is inclined toward the outdoor side. As shown in FIG. 6, the draining plate 8 is formed of an extruded aluminum member formed by bending the tilt blocking piece 8a onto one end of a base plate 8b that is fixed in contact with the lower surface of the waist panel 1. ing.

On the other hand, the lower surface of the horizontal base 6a of the adjustment plate 6 is in contact with a sealing material 9 that is fitted into a groove 2e formed on the upper surface of the rectangular frame 2a of the window panel 2 and projects. Parts other than 7 are divided. A mounting piece 5a of the bracket 5 is attached to the lower surface of the waist panel 1 on the outdoor side of the sealing material 9.
A draining material 11 is removably attached with a fastener 10 such as a screw, and the seal 9 is hidden from the outside by this draining material 11.
This drainage material 11 and window panel 2
An outside air inlet 12 is formed between the two.

Note that 13 is a catch pan disposed at the lower part of the vertical space 3a between the window panels 2, 2, and is used to catch rainwater that is blocked by the slope blocking piece 8a of the draining plate 8 and falls downward. It is designed to be discharged to the outside.

Numerals 14 and 15 are sealing materials disposed on the indoor and outdoor sides of the joint between the waist panel 1 and the window panel 2 above the waist panel 1, respectively. 3' is divided, and inside this horizontal space 3' there is a waist panel 1.
Outside air is introduced through a notch 1b provided at the upper end of the window panel 2 on the outdoor side, and the window panels 2 also communicate with the vertical space formed by the window panels 2.
Further, outside air is introduced from the lower part of the rectangular frame 2a into the glass fitting groove 2b that communicates with the four circumferences, and also into the space formed by the ridge 2f.

The waist panel 1 is fixed to the body A with a bracket 16 attached to the body A (see FIG. 2), and the window panel 2 has an upper portion attached to the waist panel 1 as shown in FIG. Connectors 1 such as bolts and nuts are attached to a bracket 17 protruding from the lower surface of the
By fitting the sash bracket 19 connected with 8 into the C-shaped groove 2f formed on the upper surface of the rectangular frame 2a, the sash bracket 19 is held hanging down, and the lower part is held between it and the waist panel 1 below. It is fixed by an anchor bolt 21 together with an intervening sash bracket 20, and is fixed between the waist panels 1, 1 in the vertical direction.

As explained above, according to the rain cover structure of this invention, a slit-shaped opening can be formed simply by attaching an adjustment plate to the upper panel, eliminating the need for drilling and allowing a large amount of outside air to be introduced. The L-shaped passage has the effect of instantly equalizing the pressure, and the presence of the L-shaped passage has the effect of making it difficult for raindrops to enter, and actively directs rainwater that has entered the horizontal space through the opening to the outside. Since it is equipped with a drainage board with an inclined stop for drainage, it is possible to instantly and uniformly equalize the pressure of the horizontal space and the space communicating with the horizontal space with the outside pressure, and also to prevent rainwater from entering the horizontal space. It has excellent effects such as being able to safely discharge water to the outside of the room, and its utility value is remarkable.
