Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a drainage structure for a curtain wall with no eyelashes.

(Prior Art) Conventionally, as a drainage structure for rainwater that has penetrated into the blind glass fitting groove in the curtain wall, a plurality of through holes that open into the hollow hollow body are provided in the bottom wall of the glass fitting groove portion. It is known that a plurality of drain holes that open to the outside of the room are provided in the seamless body. However, this conventional structure is effective for drainage because the path from the inside of the glass fitting groove to the outside through the through hole and the drainage hole is straight, but it is effective for drainage, but the backflow of wind and rain from the drainage hole into the glass fitting groove is effective. However, there is also a drawback in that it is necessary to process a plurality of through holes and drain holes, respectively.

(Problems to be Solved by the Invention) The purpose of the present invention is to eliminate the conventional drawbacks.

(Means for Solving Problems) In order to achieve the above object, the curtain wall seamless drainage structure of the present invention has a plurality of uprights and a plurality of uprights connected between adjacent uprights. Glass was attached to the lattice-shaped glass support frame consisting of eyes by fitting the upper and lower ends of the glass into the blind glass fitting groove, and the left and right ends of the glass butted against the left and right ends of the adjacent glass. In the curtain wall, the left and right adjacent longitudinal end portions are faced to each other with a small space left and right, and the longitudinal end portions of the invisible glass fitting groove portions are aligned with the invisible left and right small end portions. The end cover is attached so as to open within the space, and the surface of the end cover is opened so that the longitudinal end opening of the fitted groove portion at the lower end of the glass opens to the outside of the room through the small space between the left and right sides. Avoid opening the above-mentioned blind groove In this configuration, the receiving plate, which is formed and installed in almost two steps, is filled with the sealing material to seal the inside of the inside of the seamless small space. An embodiment of the present invention will be described below with reference to the drawings.

(Example) In FIG. 1, a plurality of cubes (1) on the building floor slab ...
Are vertically fixed to each other with a required right-and-left space by ordinary fixing means, and a plurality of blinds (2) ... are placed between the adjacent cubics (1) (1) ,. Eye (2)
(2) Horizontally connecting the long end portions of the ..., with the left and right small spaces facing each other, and connecting them horizontally (1)
... and blinds (2) ... In each grid frame of the grid-shaped glass support frame, the glass (3) is fitted on the upper and lower ends of the blinds (2) (2), ... , The right end is attached by joining together with glass.

The above-mentioned upright (1) projects a support plate (5) to an outdoor direction from the center part of the outdoor side surface of the upright base (4) having a rectangular hollow cross section as shown in the second illustration, and a small width flange (6) at the projecting end. ) Is formed.

The seamless (2) has a hollow rectangular cross section as shown in FIG. 3 and has a support plate (5) having a vertical width in the indoor / outdoor direction.
It is formed to have a width approximately twice that of the above, and the upper and lower surfaces thereof are provided with substantially U-shaped glass fitting groove portions (7) and (8) extending over the entire length, and the longitudinal end surface thereof is formed as shown in FIG. The end cover (9) is fixed with screws (10), and the glass fitting groove parts (7) and (8) are provided with end openings (11) and (12) in the end cover (9), In the end cover (9) surface, the chamber of the end cover (9) extends horizontally from the upper end slightly below the end on the lateral side in the outdoor direction,
Then, bend and hang along the indoor side of the end opening (11),
Next, attach a sealing material receiving plate (13) of approximately two-stage narrow width that bends and extends in the outdoor direction along the upper side of the end opening (12) and then bends and extends along the outer side of the opening (12). There is.

The seamless ends (2) of such a structure are placed outside the vertical bases (4) and (4) at the longitudinal end portions of the seamless eyes (2) between the adjacent left and right sides (1), (1) ,. Tight material on the side (24),
The end lids (9) and (9) are abutted via the (24), and between the left and right eyes (2) and (2) that are adjacent to each other, and the vertical support plate (5) is attached to the indoor half surface. Angled brackets (1) fixed to both sides of the vertical support plate (5) in this state, facing each other with a small space (d) between them.
4) Fix it to (14) with bolts (15) and nuts (16). The seal material receiving plates (13) and (13) of the adjacent seamless lids (9) and (9) face each other with the vertical support plate (5) sandwiched therebetween. When the seamless connection is made in this way, the sealing material (17) is filled on the opposing sealing material receiving plates (13) (13) within the small space (d) on the left and right (see FIG. 3), The inside of the small space (d) is sealed,
As a result, the end opening (11) is opened within a small space (d) communicating with the outside of the room.

The glass (3) has its upper and lower ends on the upper and lower eyes (2),
It is fitted in the glass fitting groove portions (8) and (7) of (2), and the sealing material (18) is filled between the left and right end portions of the glass fitting groove portions (8) and (7) and the abutting portions of the left and right end portions of the adjacent glass.

(19) and (19) are ridges attached to the left and right sides of the vertical support plate (5), and the tight material (20) and the sealing material (21) attached to the outside of the room are attached to the inner surface of the glass (3). Abutting.

(22) and (23) are a sealing material and a tight material between the upper and lower end portions of the glass (3) and the fitting groove portions (7) and (8).

Now, the fitting groove (7) in which the lower end of the glass (3) is fitted
When rainwater enters the inside, the rainwater passes through the fitting groove (7) and flows out from the end opening (11) into the small space (d), and then from the small space (d) to the outside of the room. Is discharged.
In addition, when wind and rain blow into the small gap (d), the end opening (11) opens on the side surface at a right angle to the small gap (d). Difficult to flow back into the groove (7).

(Effect of the device) In the present invention, the edges of adjacent glass are abutted against each other, and the inside of the glass is completely sealed, so there is no risk of rainwater intrusion, and rainwater will not enter the fitting groove at the bottom of the glass. Even if the water enters, it can be discharged to the outside of the room through the small opening between the end portions of the fitting groove portion and the small left and right intervals.
We provide a seamless drainage structure for curtain walls with a new structure that does not easily flow back into the glass fitting groove part even if wind and rain blows into the small space left and right, contributing to the enrichment of technology Is something you can do,
In addition, the use of the stitches does not require the troublesome processing work for opening a plurality of through holes and drain holes in the bottom wall of the glass fitting groove and the seamless body as in the conventional case, and the working advantage can be obtained. .
