In the figure, reference numeral 1 denotes a wall panel that forms the outer wall of a building. In this wall panel 1, an outer wall material 3 having a lower sash 4 at one end and an upper sash 5 at the other end is chased through the trunk edge 2. It is pasted horizontally and assembled. In addition, an opening 6 is provided in the wall panel 1, and an external fitting 9 such as a window sash frame 7 and a sash casing 8 is installed in the opening 6. The window sash frame 7 of the external joiner 9 is attached to the wall panel 1 by screws 11 with a sealant 10 interposed therebetween.
[0010]
When the outer wall material 3 and the window sash frame 7 are attached to the wall panel 1 in this way, an exposed portion of the wall panel 1 is formed between them, and the outer surface side of the window sash frame 7 is exposed to the outside. The sash casing 8 of the external fitting 9 is attached to the outer surface side of the window sash frame 7 so as to cover the part. The sash casing 8 is assembled by fitting a fitting claw 13 into a scratch portion 12 provided on the outer surface side of the window sash frame 7.
[0011]
In addition, a joint 14 is formed between the end face of the outer wall material 3 and the end face of the sash casing 8 which is the external joiner 9. This joint 14 needs to be sealed after rain or apparently. is there. The joint 14 is installed on the end face of the sash casing 8 and is sealed by a gasket 15 that is brought into contact with the end face of the outer wall material 3 by elastically deforming the tip of the seal portion.
[0012]
As shown in FIG. 4, the gasket 15 includes a fitting main body portion 17 fitted into a receiving portion 16 provided on an end surface on the outer wall material side of the sash casing 8, and a primary seal provided integrally with the fitting main body portion 17. A portion 18 and a secondary seal portion 19, a slit-like gap 20 provided between the primary seal portion 18 and the secondary seal portion 19, and a space portion 21 provided inside the secondary seal portion 19. .
[0013]
The primary seal portion 18 and the secondary seal portion 19 are formed with tip seal portions 22, 23, 24, and 25 that are in contact with the end surface of the outer wall material 3 and the end surface of the sash casing 8 and can be elastically deformed. The tip seal portions 22, 23, 24, and 25 are formed so as to protrude outward from the main body portion. The gasket 15 is fitted with the depth end of the slit-shaped gap 20 as a starting point, and the first cut line 26 capable of separating the primary seal portion 18 from the main body portion 17 and the second cut line capable of separating the secondary seal portion 19. 27 is set.
[0014]
The second cut line 27 includes the space portion 21 provided inside the secondary seal portion 19 and is set so as to be easily separated. As described above, the gasket 15 is configured so that the first cut line 26 and the second cut line 27 are set, and the primary seal portion 18 and the secondary seal portion 19 can be separated therefrom, and three types, that is, a primary seal are provided. It is possible to use them in three forms: a form in which the part 18 and the secondary seal part 19 are integrated, a form in which only the primary seal part 18 is cut off, and a form in which only the secondary seal part 19 is cut off.
[0015]
This is because one type of gasket 15 is selectively used according to the following three modes of use. That is, the end surface of the outer wall material 3 that forms the joint 14 with the end surface of the sash casing 8 has one end as the lower sash 4 and the other end as the upper sash 5 as described above, and is positioned on the opening 6 side. The joint 14 formed between the end surface of the sash casing 8 of the external fitting 9 depending on whether the end surface of the outer wall material 3 is the lower sash 4, the upper sash 5, or the state where the sash portion is cut. This is because the gaskets 15 need to be used properly according to the difference.
[0016]
FIG. 1 shows a form in which the end surface of the outer wall material 3 is the lower sash 4. In this case, the gasket 15 is installed in the sash casing 8 by separating the secondary seal portion 19 of the gasket 15 from the second cut line 27 and fitting the fitting main body portion 17 into the receiving portion 16 of the sash casing 8. .
[0017]
Butyl rubber 28 is sandwiched between contact surfaces of the lower sash 4 of the outer wall material 3 and the gasket 15 installed in the sash casing 8, and the fitting claws 13 of the sash casing 8 are fitted into the scratched portions 12 of the window sash frame 7. When the sash casing 8 is assembled, the end seal portions 22, 23, 24 of the primary seal portion 18 of the gasket 15 come into contact with the outer wall material 3 and the end surface of the sash casing 8 so as to be elastically deformed. The joint 14 formed therebetween is completely sealed.
[0018]
At this time, the window sash frame 7 is first attached to the wall panel 1, but the sash casing 8 into which the next gasket 15 is fitted and the outer wall material 3 are attached to the gasket 15 as long as the mounting error is small. Therefore, the outer wall material 3 and the sash casing 8 can be attached to each other.
[0019]
In addition, when the lower sash 4 of the outer wall material 3 is cut leaving all or a part thereof, the gasket 15 is not separated from the secondary seal part 19 as shown in FIG. By installing the sash casing 8 in the window sash frame 7 with both the 18 and the secondary seal portion 19 left, and fitting the sash casing 8 into the window sash frame 7, the outer wall material 3 and the sash The joint 14 formed between the end faces of the casing 8 can be sealed with a gasket 15 and sealed. In this case, although the butyl rubber 28 is not used, the sealing performance can be enhanced by the cushion effect of the space portion 21 in the secondary seal portion 19.
[0020]
Moreover, the form in case the end surface of the outer wall material 3 is the upper sash 5 is shown by FIG. In this case, the gasket 15 is installed in the sash casing 8 by separating the primary seal portion 18 of the gasket 15 from the first cut line 26 and fitting the fitting main body portion 17 into the receiving portion 16 of the sash casing 8.
[0021]
Then, the outer wall material 3 and the sash casing 8 are attached by sandwiching the butyl rubber 28 between the upper surface of the secondary seal portion 19 and the lower surface of the upper sash 5, so that a gasket is provided between the end surfaces of the outer wall material 3 and the sash casing 8. 15 and can be sealed. What is important in this case is that the tip seal portion 25 of the secondary seal portion 19 of the gasket 15 contacts the lower corner portion of the upper wall 5 of the outer wall material 3 and elastically deforms, and this portion is completely sealed. is there.
[0022]
Thus, as described above, in any of the three forms of the sealing structure in which the end wall shape of the outer wall material 3 is different, the fitting body portion 17 of the gasket 15 is fitted to the receiving portion 16 of the sash casing 8 in any case. The gasket 15 is easily installed, and the joint 14 formed between the outer wall material 3 and the end face of the sash casing 8 is sealed by the primary seal portion 18 and / or the secondary seal portion 19 of the gasket 15. Thus, the joint 14 can be completely sealed without being affected by the end face shape of the outer wall material 3, and water can be reliably stopped.
[0023]
Further, by using the gasket 15 configured as described above, the primary seal portion 18 and the secondary seal portion can be used regardless of whether the end wall shape of the outer wall material 3 is the lower sash 4, the upper sash 5, or no sash. 19 is used as it is without being cut off, or either the primary seal portion 18 or the secondary seal portion 19 is cut off from the first cut line 26 or the second cut line 27 and used. Three different forms of sealing structures can be accommodated.
[0024]
In particular, since the first cut line 26 and the second cut line 27 are set in the gasket 15 with respect to the primary seal portion 18 and the secondary seal portion 19, the gasket 15 can be easily separated from this and used. The primary seal portion 18 and the secondary seal portion 19 are provided with tip seal portions 22, 23, 24, and 25, respectively, and the tip seal portions 22, 23, 24, and 25 are used for the outer wall material 3 and the sash. Since it is elastically deformed and comes into contact with the end face of the casing 8, sealing can be performed more reliably.
[0025]
Further, since the space portion 21 is provided inside the second cut line 27, the sealing performance can be further improved by the cushion effect, and the secondary seal portion 19 is separated so as to include the space portion 21. Since the 2nd cut line 27 for this is set, when cutting off the secondary seal part 19, it can cut off easily.
[0026]
【The invention's effect】
As explained above, according to the gasket according to the present invention, it has a primary seal portion and a secondary seal portion, and the primary seal portion and the secondary seal portion are set as the first cut line and the second cut line. Can be easily separated and used as it is according to the shape of the end wall of the outer wall material, or used by separating the primary seal from the first cut line, or the secondary seal from the second cut line It can be used depending on whether it is used or not, so even if the shape of the outer wall material is changed, it is not affected by one type of gasket, and it is formed between the outer wall material and the external joinery. The joint can be reliably sealed. Particularly, since the tip seal portion of the primary seal portion and the secondary seal portion comes into contact with the end face of the outer wall material by being elastically deformed, the joint can be sealed more reliably.
