Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curtain wall which is attached to a building frame to form an outer wall.

[0002]

2. Description of the Related Art An outer wall of a building using a curtain wall has a frame structure (an external force is supported by a slab or a reinforcement connected between slabs) and a plate structure (an external force is received by the entire outer wall panel and transmitted to the slab or frame). is there. In all cases, the treatment of rainwater is important, and various measures have been taken to prevent rainwater that enters the indoor side of the wall surface from reaching the living space due to deterioration of joint materials and wind pressure.

The curtain wall disclosed in JP-A-56-41945 has a frame structure, but the vertical space between the panels and the horizontal joint space are communicated with each other, and rainwater in the horizontal joint space is raised by using a catch pan. I am trying to lead to the auxiliary space.

The curtain wall disclosed in Japanese Unexamined Patent Publication No. 56-100953 has a plate structure, in which strip-shaped waterproof moldings (gasket 11) are mounted in vertical joint spaces and outer joint spaces between outer wall panels. Rainwater is prevented from reaching the indoor wind barrier (gasket 20).

Among the plate-shaped curtain walls, a catch pan is comparatively used to discharge rainwater that has entered the vertical joint space to the outside.
No. 13, No. 62-21218, and the like.

[0006] However, in these prior arts, in the case of the plate structure, although it is guided to the outside by the catch pan, rainwater from the lateral joint space or rainwater invading from the caulking portion is compared with the vertical joint space by that time. Since it is freely falling, if the amount of moving rainwater increases, it may wet the wind barrier and gasket located on the indoor side of the vertical joint space, and may enter the indoor side beyond these.

Further, when the outer wall of the building is composed of a curtain wall, the frame structure and the plate structure may be alternately combined up and down, but there is no disclosure regarding rainwater treatment for the entire wall surface in such a case.

On the other hand, the wall surface of the building may be inclined from the viewpoint of design or due to the limitation of the slant line. However, since the rainwater is more likely to stay in the inclined wall surface than the vertical wall surface, when the curtain wall is used, the vertical and horizontal joints are jointed. The risk of leaking water from the space increases.

[0009]

SUMMARY OF THE INVENTION It is an object of the present invention to ensure rainwater treatment on a curtain wall, prevent water leakage to the indoor side, and provide a water-stop molding used for this purpose. .

[0010]

[Means for Solving the Problems] In a curtain wall having a plate structure, a strip-shaped water-blocking molded body having a water catching catch pan at the upper part and a drain catch pan with the drain catch pan as the lower part in the vertical joint space of the outer wall panel. It is installed and a drainage path is formed on the outdoor side of the water blocking molded body. This limits the movement of rainwater from the lateral joints on the upper side of the outer wall panel or the rainwater that has entered from the caulking location to the outdoor side of the vertical joint space and prevents the ingress of the indoor side.

The first drainage path has a water receiving plate whose front edge faces the drainage catch pan between the drainage catch pan and the lower end of the strip-shaped water blocking molded body having the water catching catch pan on the upper portion. May be prepared. Further, the water receiving plate may be formed integrally with the water blocking molded body.

The strip-shaped molded body for stopping water comprises a catch pan and a main body. The catch catch pan and the main body are integrally molded. The catch catch pan is formed by inclining upward from the upper end of the main body part indoors to a position where it can cover the upper surface of the weather strip arranged on the indoor side between the adjacent panels on the left and right. The main body is formed vertically. In the cross section, the central part of the water catching catch pan and the main body part may be a groove part that is recessed toward the indoor side, and the main body part may have a gutter part that has grooves open to the outdoor side on both sides of the groove part. . The water catch catch pan and the main body may be formed of a weather resistant elastomer.

The bottom surface of the water receiving box 47 is inclined downward in the outdoor direction,
Flexible fins 51 are provided on both edges of the upper end of the water container 47.

The water receiving plates 43 are the left and right frames 8c and 8d.
It is attached right above the drainage catch pan Q on the opposite side of the above, and the tip edge is projected from both sides onto the water receiving box 47 (FIGS. 1 and 17). A space defined by the panel vertical frame auxiliary member 38 is located above the water receiver 43, and the panel vertical frame auxiliary member 38 is cut out from this position at the lower side (FIG. 1).
3).

When the left and right outer wall panels 6 are assembled, the strip-shaped water blocking molded body 42 and the drainage catch pan Q have the drainage catching pan Q in the vertical joint space 35 between the panels 6 and 6 for the water blocking molded body. The water blocking molded body 42 is disposed below the weather strip 36 and is disposed at a position closer to the outdoor side than the weather strip 36. The water blocking molded body 42 has the sealing material 5 between the left and right frames 8c and 8d around the upper catchment catch pan P.
It is fixed by being filled with 2 (FIG. 11). It should be noted that the sealing material 52 is provided above the catch catch pan P so as to leave the upper end surface of the vertical joint space 35 and the panel vertical frame auxiliary material 38.
Close the upper end surface of the space created by (3rd drainage path c). However, the horizontal joint 17 on the upper side of the plate structure portion 3 has a space on the indoor side, and this space is connected to the first drainage route (a) and the third drainage route (c) at both ends.

The drainage catch pan Q is located in a lower portion of the vertical joint space 35 at a position which should be called a cutout space in which various fins (for attaching the weather strip 36, etc.) on the opposing surfaces of the frames 8 (c, d) are cut off. The mounting flange 49 is fitted into the L-shaped metal fittings 53 attached to the left and right frames 8 (c, d), and is attached to the lower portion of the vertical joint space 35. At this time,
The flexible fins 51 attached to the upper edges (left and right sides) of the water receiving chamber 47 are closely attached to the wall surface of the frame 8 (c, d), and are provided on the indoor upper edge and the indoor edge of the water receiving chamber 47. Strict sealing 54 is performed using the water blocking wall 50 (FIG. 14).

In FIG. 14, reference numeral R is an auxiliary catch pan located below the drain catch pan Q,
The structure is designed to receive the entire area of the space created by the vertical joint space 35 and the panel vertical frame auxiliary material 38 (Fig. 16). It is discharged from the through hole 55 to the outdoor side of the vertical joint 18 (FIG. 9).

The band-shaped water blocking molded body 42 can also be mounted by inserting the outer wall panels 6 on both sides and then inserting it from the open upper end of the vertical joint space 35. Similarly, the drain catch pan Q can also be mounted from the indoor side by utilizing the above-mentioned cutout space after the outer wall panels 6 on both sides are attached.

In this way, the drainage route (a) is formed. Then, the rainwater that has moved downward through the second drainage path (b) formed inside the upright 13 is received by the catch catch pan P and moves downward as it is to the drain catch pan Q, where the drain pipe It is discharged from 48 (FIGS. 17 and 18). Since the rainwater from the vertical lower joint seal 19b is close to the catch catch pan P, it is directly received by the catch pan P, reaches the drain catch pan Q, and is discharged to the outside.

Rainwater from the lower glass seal 20b is collected in the panel water receiving member 14 and moves from the water draining hole 33 to the upper frame 8a, which is moved in the direction of the frontage, so that the left and right frames 8c and 8d are indoors and outdoors. From the water cutout 56 provided at the upper end of the direction wall, the water catches the catch pan P. Then, it reaches the drain catch pan Q and is discharged to the outside. The place where rainwater from the panel joint seal 37 enters is the drainage route (a), reaches the drainage catch pan Q, and is discharged to the outside.

Rainwater from the panel unit joint seal 39 moves toward the front along the secondary seal 23 and is guided to the third drainage route (c) through the openings provided in the left and right frames 8c and 8d. Move down. The rainwater that has moved downward eventually reaches the water receiving plate 43, and the drain catch pan Q
Is discharged to the outside. The location where rainwater from the panel unit side seal 41 enters is the third space 40.
It is the drainage route (c), and also reaches the water receiving plate 43, is guided to the drainage catch pan Q, and is discharged to the outside. A water receiving portion 57 (FIG. 17) formed of a sealing material is provided in the lower portion of the space 40 to guide the rainwater moving downward to the discharge catch pan Q side.

As described above, the rainwater entering the indoor side of the frame structure portion 4 has a cubic shape except for the blind portion 12.
The collected rainwater is discharged from the lower end of the upright 13 through the first drainage path (a) of the vertical joint space 35 of the plate structure 3 to the outside. Also, the plate structure 3
Rainwater that has entered the indoor side from each joint part is discharged from the drain catch pan Q to the outside through the first drainage route (a) or the third drainage route (c). That is, all the rainwater that enters the indoor side from the wall surface of the curtain wall 1 reaches the drain catch pan Q through the drainage paths (a), (b) and (c) of the vertical joint space 35 and is discharged to the outside.

Therefore, the rainwater that has entered the indoor side is promptly discharged and does not stay. Further, the upper end surface of the vertical joint space 35 in the plate structure portion 3 is completely shielded by the catching catch pan P and the sealing, and the strip-shaped water blocking molded body 42 allows the vertical joint space 35 to be located on the indoor side and the outdoor side. Since it is completely separated, rainwater does not enter the indoor side where the weather strip is located.

The above is an embodiment, and the invention of the present application is not limited to the illustrated concrete structure. Although the described curtain wall 1 forms an inclined wall surface, there is no substantial difference even when forming a vertical wall surface. Plate structure part 3
Form a panel unit joint by being separated into a large outer wall panel 6a and a small outer wall panel 6b, but the outer wall panel may have a single structure. Frame structure part 4
The same applies to the daylighting panel 11. Although the band-shaped water blocking molded body 42 is configured to integrally mold the water catching catch pan P and the main body S, the lower water receiving plate 43 may be molded integrally.

[0053]

It's smooth. Moreover, since the strip-shaped water blocking molded body having the catch catch pan and the drain catch pan prevent rainwater from moving more indoors than these, there is no risk of leaking water to the living space.

Further, since the water catching catch pan and the main body are integrally formed as a band-shaped water blocking molded body, it is easy to handle and the construction time of the curtain wall can be shortened. Also, since the whole is a molded product, it is unlikely to be twisted and attached, and rainwater can be guided reliably.

According to the second aspect of the invention, in the vertical joint space between the outer wall panels, the rainwater, which is likely to travel along the wall surface of the panel frame, is guided by the water receiving plate onto the drain catch pan, so that the indoor side Collecting and draining rainwater that entered will be reliable. According to the configuration of claim 3, since the water receiving plate is integrally formed with the water catching catch pan and the main body as a water blocking molded body, the number of parts is small and the vertical joint space between the outer wall panels is small. In addition, the work of constructing the first drainage path becomes easier. According to the structure described in claim 4, it is possible to quickly discharge the water leaking between the outer wall panels of the curtain wall to the outdoor side without reaching the indoor side. Also, easy to handle,
Easy to install.

According to the fifth aspect of the invention, the rainwater that is collected in the catch catch pan and moves downward along the main body is collected in the center of the first drainage channel, and the downward movement due to gravity is promoted. It In addition, since there is little flow in the connecting portion between the both sides of the water blocking molded body and the frame of the panel adjacent to the left and right, the risk of water leakage from this portion is reduced. Claim 6
