Lightweight panels have porous surfaces, low strength, and cannot be compressed, making it difficult to keep them watertight. Normally, waterproof foam material is compressed to 1/8 and set, but since it is adhered to the surface of the lightweight panel with a primer or the like, its water resistance is not good.
本考案の目的は、このような止水が困難な箇所

The water-stopping material of the present invention has a layered structure in which a water-swellable resin layer is sandwiched between non-water-swellable resin layers in the form of a side German arch. It is characterized in that the groove formed smaller than the size of the groove is filled with an adhesive substance made of a water-swellable urethane substance in liquid or paste form.

また非水膨潤性樹脂としては、柔軟性のあるポ
リウレタンフオーム等を用いるのが好ましい。 Further, as the non-water swellable resin, it is preferable to use flexible polyurethane foam or the like.
本考案の止水材の一例を第１図に示す。 An example of the waterproof material of the present invention is shown in FIG.

２ａ及び２′ａにより溝部が形成されている。な
おこのような溝部は止水材１の片側だけに形成し
てもよいのはもちろんである。 The water-stopping material 1 is composed of a water-swellable resin layer 3 sandwiched between non-water-swellable resin layers 2 and 2' in a sandwich shape,
In addition, since the non-water-swellable resin layers 2 and 2' are wider than the water-swellable resin layer 3, grooves are formed in the water-stopping material 1 by the convex parts 2a and 2'a. It goes without saying that such a groove may be formed only on one side of the water stop material 1.

In Fig. 2, reference numerals 5 and 5' indicate lightweight panels, and the water-stopping material 1 of the present invention is inserted into their joints.At this time, the water-stopping material 1 should be slightly larger in width than the joint. , its convex portions 2a, 2'a
The adhesive substance 4, 4' flows out between the waterproof material 1 and the lightweight panels 5, 5' and spreads out as a thin layer. Therefore, the space between the joints is reliably sealed.

According to the water stop material of the present invention as described above, since a water-swellable substance is used, even if water enters, the water-swellable resin layer expands and reliably closes the gap, and the adhesive surface also Because it is strongly bonded, water can be effectively stopped even on the joining surfaces of lightweight panels, which are normally difficult to stop.
