[0016]

In the invention according to the first aspect of the present invention, an integrated product of the waterproof block and the backup material is inserted into the recess while the adhesive layer on one side is covered with release paper, and the adhesive on the bottom is The layer is applied to the bottom of the recess. Thereafter, the release paper is removed, and the adhesive layer on one side is attached to the side of one panel. At this time, since the adhesive layer on one side is covered with release paper, the adhesive layer on one side is attached to the panel side,
There is no inconvenience that the waterproof block cannot be inserted to the bottom of the recess, and the top edge of the release paper rises long upward, so even if the width of the recess is narrow, the release paper can be easily removed. Becomes possible.

Further, in the invention according to claim 2 of the present invention, the adhesive layers formed on both side surfaces of the waterproof block are covered with different release papers. For this reason, even if the width of the concave portion and the lateral width of the waterproof block and the backup material are almost the same, it can be inserted without any problem, and each release paper can be sequentially removed, so that the construction is easy.

In the invention according to claim 3 of the present invention, an adhesive layer is formed on at least one side surface and the bottom surface of the waterproof block.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIGS. 1 and 2 show a sealing device between panels according to a first embodiment of the present invention. This sealing device is composed of a waterproof block 1, a backup material 2, and a release paper 3 covering these.
These are inserted and arranged in a concave portion 6 formed between the side surfaces of the pair of panels 4 and 5. Then, the gap 6a formed at the bottom of the concave portion 6 is completely sealed by the sealing device. 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 rectangular rod having a width substantially the same as the width of the concave portion 6, and the waterproof block 1 is made of a soft, tacky material. Manufactured using non-vulcanized butyl rubber, and therefore the entire outer surface is an adhesive surface.

As shown in FIGS. 1 and 2, the backup material 2 is formed in a square rod shape having a width substantially equal to the width of the recess 6 using, for example, a closed-cell foam of synthetic resin. The backup material 2 is disposed 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 corresponds to FIGS.
As shown in FIG. 3, the waterproof block 1 includes a bottom surface release paper 3a corresponding to the bottom surface and a side surface release paper 3b corresponding to each side surface of the waterproof block 1. Each side release paper 3b has an upper edge backed up. The backup material 2 is raised up to the upper side of the material 2 with a length of about the width of the backup material 2. Before use, the rising portion is folded by being superimposed on the backup material 2 and partially stopped by the adhesive tape 7 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 FIGS. 1 and 2, the waterproof block 1 is bent inward, and the bent portions cover both side edges of the bottom surface of the waterproof block 1.

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

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

Next, the operation of the present 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. To expose. At this time, release papers (not shown) on both end surfaces in the longitudinal direction of the sealing device are 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 adhered 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 papers 3b, there is no problem that the side surfaces of the waterproof block 1 are stuck to the side surfaces of the panels 4 and 5 and cannot be inserted to the bottom. . Also, since the lower edge of each side release paper 3b is bent inward and covers the bottom edge of the waterproof block 1, the lower edge of each side release paper 3b is not fit when inserted into the recess 6. There is no problem that it comes off easily.

When the bottom surface of the waterproof block 1 is adhered to the bottom surface of the concave portion 6 in this manner, each side release paper 3b is gripped 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 out of the recess 6. However, even in this case, the upper edge of each side release paper 3b is
Since the finger extends to near the opening end of the recess 6, the finger is
Each side release paper 3b can be easily grasped by slightly inserting it into the inside. If this operation is performed at one end in the longitudinal direction of the sealing device, the entire operation is performed outside the concave portion 6, so that there is no problem in actual use.

When 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 concave portion 6, and since the non-vulcanized butyl rubber, which is the material of the waterproof block 1, is rich in flexibility, the above-mentioned pressing causes the pressing of FIG. As shown in (1), the bottom surface and both side surfaces of the waterproof block 1 are completely adhered to the inner surface of the concave portion 6, and the gap 6a can be completely sealed.

After the above operations are sequentially performed in the longitudinal direction of the concave portion 6, the backup material 2 is filled with a sealing material 9 such as a caulking material, as shown in FIG. At this time, the width of the backup material 2 is set to be substantially the same as the width of the recess 6, and the side surface of the backup material 2 is
Even if a gap is formed between the sealing material 9 and the inner surface, the sealing material 9 can be filled as it is without filling the gap with a padding or the like because the gap is extremely narrow.

The work is completed only by inserting the sealing device into the concave portion 6 with the bottom release paper 3a removed, and then removing the side release paper 3b. Thus, a complete sealing effect can be obtained. Since the non-vulcanized butyl rubber, which is the material of the waterproof block 1, reacts with the CaO component in the cement to form an ionic bond, the non-vulcanized butyl rubber is chemically and strongly bonded and integrated in the concave portion 6, so that it is not simply bonded. Also, a large water stopping effect can be obtained.

Further, since the release paper 3 also serves as a packaging material for 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 cope with the wide recess 6, the lateral width of the waterproof block 1 and the backup material 2 is enlarged according to the width of the recess 6. The upper edge of the release paper 3b on both sides is abutted on the backup material 2 and is fixed with the adhesive tape 7. In other respects, the configuration is the same as that of the first embodiment, and the operation is the same.

According to this embodiment, the same effects as those 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 in place of the waterproof block 1 in the first embodiment.

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

When the gap 6a of the recess 6 is sealed with a 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 an adhesive layer is formed on the right side surface in FIG. 5 of the waterproof block 11, this adhesive layer is not only used but also obstructive.

However, according to the present embodiment, the first
The same effect as that of 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 before filling the sealing material 9 (see FIG. 1). It is preferable to close the gap by fixing. Further, since the release paper 3 cannot be used as the packaging material of the entire sealing device, the whole packaging is performed by another packaging material.

In each of the above embodiments, the case where the width of the waterproof blocks 1 and 11 and the width 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.

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 paper, the width of the concave portion is small. 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.

According to the invention of 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 concave portion and at least one panel side surface, a sufficient secondary sealing effect can be obtained, and the construction is easy.

Further, 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, since the lower edge of each side release paper is bent inward so as to cover the edge of the adhesive layer on the bottom surface, only the bottom release paper is used. When it is removed and inserted into the recess, there is no risk of the side release paper coming off carelessly.

In the invention according to claim 6 of the present invention, since the width of the waterproof block and the backup material are 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. Thus, a sufficient secondary sealing effect can be obtained, and when the sealing material is filled on the backup material, there is no need to seal between the both side surfaces of the backup material and the inner surface of the concave portion by other means.

Further, the invention according to claim 7 of the present invention provides:
Since the waterproof block is formed of non-vulcanized butyl rubber having adhesiveness, the waterproof block can be completely adhered to the inner surface of the concave portion, and the backup material can be fixed simply by overlapping on the waterproof block. . In addition, since the non-vulcanized butyl rubber is chemically and strongly bonded and integrated in the concave portion, a water stopping effect larger than mere bonding is obtained,
Moreover, the effect can be made permanent.
