DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. 1 and 2 show a sealing device between panels according to a first embodiment of the present invention. This sealing device includes a waterproof block 1, a backup material 2 and a release paper 3 for covering them.
Are provided, and these are inserted and arranged in a recess 6 formed between the side surfaces of the pair of panels 4 and 5. The gap 6a formed at the bottom of the recess 6 is completely sealed by this sealing device. Note that this will be described later in detail.

As shown in FIGS. 1 and 2, the waterproof block 1 is formed in the shape of a square rod having a width dimension substantially the same as the width of the recess 6, and the waterproof block 1 is a soft adhesive material. Manufactured by using non-vulcanized butyl rubber, and therefore, the entire outer surface thereof is an adhesive surface.

As shown in FIGS. 1 and 2, the backup material 2 is formed into a rectangular rod shape having a width dimension substantially the same as the width of the recess 6 by using, for example, a closed cell foam made of synthetic resin. The backup material 2 is arranged on the upper surface of the waterproof block 1 and is fixed to the waterproof block 1 by the adhesive force of the waterproof block 1.

Further, the release paper 3 is the same as that shown in FIGS.
As shown in FIG. 2, the bottom surface release paper 3a corresponding to the bottom surface of the waterproof block 1 and the side surface release paper 3b corresponding to each side surface of the waterproof block 1 are provided, and the top edge of each side surface release paper 3b is a backup. The backup material 2 is erected up to a position above the material 2 with a length of about the width dimension. Before the use, the rising portion is folded and overlapped with the backup material 2 and is partially stopped by the adhesive tape 7 so as to also serve as a packaging material for the backup material 2.

On the other hand, the lower edge of each side release paper 3b is
As shown in FIG. 1 and FIG. 2, the waterproof block 1 is bent inward, and both side edges of the bottom surface of the waterproof block 1 can be covered by this bent portion.

As shown in FIG. 2, a dividing line 8 formed by continuous cut lines or intermittent cut lines is provided between each of the side surface release papers 3b and the bottom surface release paper 3a. With this dividing line 8, while leaving the release paper 3b on both sides,
Only the bottom release paper 3a can be removed first.

Both longitudinal end surfaces of the waterproof block 1 and the backup material 2 are covered with an extension portion of the bottom surface release paper 3a or the side surface release paper 3b or an end surface release paper (not shown) separate from these, Therefore waterproof block 1
The entire outer surface of the backup material 2 is covered with release paper. That is, the release paper also serves as the packaging material for the entire sealing device.

Next, the operation of this embodiment will be described.
When sealing the concave portion 6, first, as shown by a chain line in FIG. 2, the adhesive tape 7 is removed to raise the upper edge of each side release paper 3b, and the bottom release paper 3a is removed to remove the bottom surface of the waterproof block 1. Expose. At this time, the release paper (not shown) on both end faces of the sealing device in the longitudinal direction is also removed.

Next, this is inserted into the recess 6 as shown in FIG. 1B, and the bottom surface of the waterproof block 1 is attached to the bottom surface of the recess 6. At this time, since both side surfaces of the waterproof block 1 are covered with the side release paper 3b, there is no problem that the side surface of the waterproof block 1 is stuck to the side surface of each panel 4 and 5 and cannot be inserted to the bottom. . In addition, since the bottom edge of each side release paper 3b is bent inward and covers the bottom edge of the waterproof block 1, the bottom edge of each side release paper 3b is uncovered when it is inserted into the recess 6. There is no problem that it peels off easily.

After the bottom surface of the waterproof block 1 is adhered to the bottom surface of the recess 6 in this manner, each side release paper 3b is grasped by its upper edge while lightly pressing the upper surface of the backup material 2 with a finger. Pull out and remove each. At this time, since the upper edge of each side release paper 3b extends to the outside of the recess 6, even if the width of the recess 6 is narrow, the side release paper 3b can be grasped and removed without any trouble.

Depending on the depth of the recess 6, the upper edge of each side release paper 3b may not protrude outside the recess 6, but even in this case, the upper edge of each side release paper 3b is
The finger extends to the vicinity of the open end of the recess 6, so
Each side release paper 3b can be easily grasped by inserting the inside a little. If this work is performed at one end in the longitudinal direction of the sealing device, all the work thereafter will be performed outside the recess 6, and there is no problem in actual use.

After the release paper 3b on both sides is removed in this way, the upper surface of the backup material 2 is strongly pressed. The width of the waterproof block 1 is set to be substantially the same as the width of the recess 6, and the non-vulcanized butyl rubber, which is the material of the waterproof block 1, is highly flexible. As shown in FIG. 5, the bottom surface and both side surfaces of the waterproof block 1 can be completely adhered to the inner surface of the recess 6, and the gap 6a can be completely sealed.

After the above work is sequentially performed in the longitudinal direction of the recess 6, the backup material 2 is filled with a sealing material 9 such as caulking material as shown in FIG. 1 (c). At this time, the lateral width dimension of the backup material 2 is set to be substantially the same as the width of the concave portion 6, and the side surface of the backup material 2 and the concave portion 6 are set.
Even if a gap is formed between the inner surface and the inner surface, since this gap is extremely narrow, it is possible to directly fill the sealing material 9 without filling the gap with a filler or the like.

Since the work is completed simply by inserting the sealing device into the recess 6 with the bottom surface release paper 3a removed and then removing the side surface release paper 3b, the workability is extremely good and the time is short. It is possible to obtain a perfect sealing effect. The non-vulcanized butyl rubber, which is the material of the waterproof block 1, has a carboxyl group that reacts with the CaO component in the cement to form an ionic bond. A great water-stopping effect can be obtained.

Further, since the release paper 3 also serves as the packaging material of the sealing device, the amount of dust generated on site can be reduced and the cost can be reduced by simplifying the packaging.

FIG. 3 shows a second embodiment of the present invention. In order to correspond to the wide concave portion 6, the lateral width dimensions of the waterproof block 1 and the backup material 2 are enlarged according to the width of the concave portion 6, and The upper edge of the side release paper 3b is abutted on the backup material 2 and fixed by the adhesive tape 7. In other respects, the structure is the same as that of the first embodiment and the operation is the same.

Therefore, according to the present embodiment, the same effect as that of the first embodiment can be expected.

FIGS. 4 and 5 show a third embodiment of the present invention, in which a waterproof block 11 is used instead of the waterproof block 1 in the first embodiment.

That is, the waterproof block 11 is shown in FIG.
As shown in FIG. 5 and FIG. 5, the waterproof block 1 of the first embodiment has the same shape and size, but the material is made of, for example, soft normal rubber, and the backup material 2 is fixed on the upper surface thereof. There is. An adhesive layer 11a is formed on the bottom surface, one side surface and both end surfaces in the longitudinal direction of the waterproof block 11, the adhesive layer 11a on the bottom surface is covered with the bottom surface release paper 3a, and the adhesive layer 11a on one side surface is formed.
Is covered with side release paper 3b. Further, the adhesive layers (not shown) on both end faces in the longitudinal direction are covered with the bottom surface release paper 3a or the side surface release paper 3b, or a release paper separate from these, as in the first embodiment. . In other respects, the structure is the same as that of the first embodiment and the operation is the same.

By the way, when the gap 6a of the recess 6 is sealed by the sealing device, the minimum required is the adhesive layer 11a on the bottom surface and one side surface of the waterproof block 11, as shown in FIG. In particular, as shown in FIG. 5, when the width of the recess 6 is wider than the width of the sealing device,
Even if a pressure-sensitive adhesive layer is formed on the right side surface of the waterproof block 11 in FIG. 5, this pressure-sensitive adhesive layer is not used, but rather an obstacle.

However, according to this embodiment, the first
The same effect as the embodiment can be expected. However, as shown in FIG. 5, when a large gap is formed between the sealing device and the concave portion 6, the closing plate 12 is placed on the backup material 2 prior to filling the sealing material 9 (see FIG. 1). It is preferable to fix and close the gap. Further, since the release paper 3 cannot be used also as a packaging material for the entire sealing device, the entire packaging is performed with another packaging material.

In each of the above-described embodiments, the case where the horizontal width dimensions of the waterproof blocks 1 and 11 and the horizontal width dimension of the backup material 2 are the same has been described.
The width of the waterproof blocks 1 and 1 may be slightly larger or smaller than the width of the backup material 2.

The invention according to claim 1 provides a waterproof block and a backup material,
Insert the adhesive layer on the side into the recess with the release paper still covered, and attach the adhesive layer on the bottom to the bottom of the recess, then remove the release paper and attach the adhesive layer on the side to the panel side. Therefore, a sufficient secondary sealing effect can be obtained, and the construction is extremely easy.

Further, in the invention according to claim 2 of the present invention, since the adhesive layers formed on both side surfaces of the waterproof block are covered with separate release papers, the width of the recess is narrow. Also, since the waterproof block and backup material can be inserted very easily, and each release paper can be removed sequentially,
Construction is easy. Further, since a wide sticking surface can be secured, a more sufficient secondary sealing effect can be obtained.

In the invention according to claim 3 of the present invention, since the adhesive layer is formed on at least one side surface and the bottom surface of the waterproof block, the waterproof block can be simply inserted into the recess together with the backup material. Can be attached to the bottom surface of the recess and the side surface of at least one of the panels, a sufficient secondary sealing effect can be obtained, and the construction is easy.

In the invention according to claim 4 of the present invention, since the release paper itself also serves as the packaging material of the sealing device, it is not necessary to use a special packaging material. Therefore, generation of unnecessary dust can be suppressed, and cost can be reduced.

In the invention according to claim 5 of the present invention, the bottom edge of each side release paper is bent inward so that the edge of the bottom adhesive layer can be covered. There is no risk that the side release paper will be inadvertently peeled off when removed and inserted into the recess.

Further, in the invention according to claim 6 of the present invention, since the width dimension of the waterproof block and the backup material is set to be substantially the same as the width of the recess, only the waterproof block and the backup material are inserted into the recess. With this, a sufficient secondary sealing effect can be obtained, and when the sealing material is filled on the backup material, it is not necessary to seal the space between both side surfaces of the backup material and the inner surface of the recess by other means.

Further, the invention according to claim 7 of the present invention is
Since the waterproof block is made of non-vulcanized butyl rubber that has adhesiveness, the waterproof block can be completely adhered to the inner surface of the recess, and the backup material can be fixed simply by stacking it on the waterproof block. . In addition, since non-vulcanized butyl rubber is chemically and firmly bonded and integrated in the recess, a greater water blocking effect can be obtained than simple adhesion.
Moreover, the effect can be made permanent.
