Detailed below based on the accompanying drawings for an embodiment of a longitudinal joint sealing material of the present invention. Prior to the description of the embodiment, a reference example of the present invention will be described. FIG. 1 is a partially exploded perspective view showing a main part of a vertical joint sealing material 20 according to a reference example of the present invention, and FIG. 2 is defined between opposing end surfaces of each residential outer wall panel OWP as in FIG. 2 is a front view showing the vertical joint VJ and the horizontal joint HJ, and FIG. 3 is a longitudinal sectional view cut along the line AA of FIG. Main configuration of the reference example longitudinal joint sealing material 20 shown in Figures 1-3, similarly to that of the conventional vertical joint sealing material 10 described above, the longitudinal joint sealant VS mounted on the longitudinal joint VJ is For example, solid rubber represented by ethylene-propylene solid rubber material, ethylene-propylene sponge rubber material, sponge rubber material, thermoplastic elastomer material such as styrene, olefin, vinyl chloride, urethane, or heat The gasket GK is made of a rubber-like elastic material such as a plastic elastomer foam material, and is usually elongated and extruded into a bowl-like cross-sectional shape.
[0018]
In addition to the gasket GK, the main part of the vertical joint seal material 20 of the reference example bridges the opposing end surfaces of the respective exterior wall panels OWP on the back side of the vertical joint VJ, and is connected to the vertical joint VJ. A waterproof sheet member 21 disposed along the sheet, a sheet extension 21a of the waterproof sheet member 21 that further extends from an end of the vertical joint VJ so as to intersect the horizontal joint HJ, and the sheet extension. And a sheet extension fixing member 24 that seals an end of the vertical joint VJ so as to be in close contact with 21a and to bridge between the mouths CS of the respective outer wall panels OWP for homes.
[0019]
The water-stop sheet member 21 has a foamed material such as an ethylene-propylene sponge rubber material or a urethane sponge rubber material on the surface of a sheet-like support 22 made of a non-foamed material such as an ethylene-propylene solid rubber material or a chloropyrene rubber material. 23 is layered. The sheet extension fixture 24 is formed by layering a foam 26 on the surface of a metal angle member 25 having an L-shaped cross section. On the other hand, the sheet extension portion 21a is a panel base member disposed along the horizontal joint HJ so as to bridge at least the horizontal joint HJ on the back side of each of the residential outer wall panels OWP in the vertical joint VJ. As shown in FIG. 1, the back surface of the support 22, that is, the surface not having the foamed material 23 is placed on 29.
[0020]
Thereafter, as shown in FIG. 3, one surface of the sheet extension portion fixture 24 having the foam 26 is bridged between the mouths CS of the outer wall panels OWP for homes, and the vertical joint VJ. Each screw which covers the end portion and whose other surface is in close contact with the sheet extension portion 21 a placed on the panel base member 29 and is inserted through each screw notch portion 28 provided in the angle member 25. The member 27 is fixed in close contact with the end of the vertical joint VJ and the sheet extension 21a.
After that, the periphery of the angle member 25 is filled by filling the inside of the horizontal joint HJ with an irregular sealing material S such as a normal caulking material as a horizontal joint sealing material, and the water stop treatment is completed.
[0021]
By the water-stopping treatment as described above, the foam 26 of the angle member 25 is formed on the opposite ends of the outer wall panels OWP for the housing, the end CS of the vertical joint VJ, and the surface of the seat extension 21a. Even in a slightly non-uniform state, the sealing property is maintained at an appropriate level by the elastic deformation.
Further, in place of the foam, an uncrosslinked or semi-crosslinked butyl-based or acrylic-based adhesive material can also be used. The water-stop sheet member 21 is modified so that the support 22 is removed and only the foam 23 is formed into a sheet shape, depending on conditions such as the arrangement range of the panel base member 29. Is also possible.
[0022]
FIG. 4 is a perspective view of a seat extension fixture 34 which is a modification of the seat extension fixture 24. In this modified example, a foam 36 is layered on the surface of a metal angle member 35 having an L-shaped cross section, while each screw notch 38 for each screw member 37 is provided, Further, an easily deformable notch portion 39 is provided between the screw notch portions 38 to give a degree of freedom to cope with deformation of the angle member 25 to the facing surface.
[0023]
FIG. 5 is a perspective view of a seat extension fixture 44 which is another modification of the seat extension fixture 24. In this modified example, a foam 46 is layered on the surface of a metal angle member 45 having an L-shaped cross section, while each screw notch 48 for each screw member 47 is provided, Further, a plurality of easily deformable cutout portions 49 and 50 are provided on each side of the angle member 45 to give a further degree of freedom to cope with deformation of the angle member 45 on the opposing surface.
[0024]
FIG. 6 is a perspective view showing an embodiment of the vertical joint sealing material of the present invention. In the embodiment shown here, the seat extension portion 21a is connected to the end portions of the respective cut ends CS and the vertical joints VJ of the outer wall panels OWP for each house as compared with the longitudinal joint sealing material 20 shown in FIG. It is different in that it is folded back so as to be covered and is fixed to each of the mouthpieces CS via the angle member 25. In this embodiment , the sheet extension fixtures 24, 34, and 44 depend on the elastic deformation of the folded sheet extension 21a even if the foams 26, 36, and 46 are removed. The metal angle members 25, 35, and 45 can be used alone. Further, if the adhesive material is used instead of the foams 26, 36, 46, the back surface 2 of the sheet extension 21a can be more reliably adhered.
