方法(I!1図−B)がある。<Conventional technology and its problems> Conventionally, the water sealing method for joints of precast concrete panels, ALC panels, siding materials, concrete segments for tunnels, concrete slabs for railways and bridges, etc. has been filled with 5 sealants. Although this is common, there is a method of sandwiching adhesive non-vulcanized synthetic rubber standard sealing material S to simplify the construction (Fig. 1-A), and a method as shown in Japanese Utility Model Publication No. 49-10524. Butyl rubber adhesive layer S around sponge rubber P
There is a method of using a backing rubber with a composite structure, such as one wrapped with rubber (I!1-B).

クアツプ材6を挿入してからシーリング材Cを施工する
工法(第1図−〇)も行われている。In addition, in consideration of the expansion and contraction of the joint, a vulcanized rubber sheet r with a width several times the width of the joint is fixed in advance with adhesive α, and after inserting the back-up material 6 on top of it, the sealing material C is applied. The construction method (Figure 1-○) is also being used.
しかしながら、これらの工法には次のような問題点があ
る。However, these construction methods have the following problems.

地の凹凸のため被着面への接触が十分でなく、漏水事故

大きいと簡単に切断され、シーリング効果がなくなって
しまう。In other words, in the method of sandwiching the standard sealing material S, it does not make sufficient contact with the surface to be adhered due to the unevenness of the base, which can easily cause water leakage accidents, and it also has poor elasticity, so it can be easily damaged if there is large movement at the joint. It will be cut and the sealing effect will be lost.

い。In the case of a composite with sponge rubber P as the core material, the adhesive area with the base is increased due to the restoring force of the internal sponge, improving sealing performance, and it also has the characteristic of being able to follow the movement of the joint. , core sponge rubber p
Because it has a closed cell structure, there is no volume change due to compression, so it cannot be loaded smoothly into narrow joints. Therefore, when applied to existing joints, there is no flexibility in dealing with variations in joint width. In addition, since the unvulcanized rubber is exposed, it has poor weather resistance, and unless a finishing material is applied, the unvulcanized rubber ages and the sponge rubber core material ages, resulting in low durability.

ある。In addition, in the construction method using vulcanized rubber as the secondary seal, the secondary seal part has sufficient elasticity and is excellent in durability, but the -second seal part C is susceptible to vibration and easily breaks. As a result, water accumulates in the secondary seal, causing water leakage. In addition, the construction process, including pre-adhesion treatment, adhesive application and drying, is complicated and takes a long time, and the recent shortage of sealant installers has become a serious problem. The present invention has been made with the aim of eliminating the above problems.

It is most preferable that the compression hardness at the time of % compression is 5 to 250 g/an'. A specific example of such a rubber sponge is Pat Sealer (trade name of semi-open foam sponge manufactured by Sekaicho Co., Ltd.).

る。These semi-open foam sponge rubbers are flexible and have excellent followability because their volume decreases when compressed. If such a sponge body is used as a core, loading into narrow joints can be carried out extremely smoothly and reliably.

きる。The vulcanized rubber sheet 2 may be a general-purpose waterproof sheet such as an ethylene propylene copolymer rubber sheet or a chloroprene rubber sheet with a thickness of about 0.5 to 2.0 mm, which is used for roof waterproofing work of ordinary buildings, or Examples include polyvinyl chloride sheets that function equally well as these. The adhesive 3 between the foam 1 and the vulcanized rubber sheet 2 may be a chloroprene rubber solvent-based adhesive (for example, Sekaicho Co., Ltd., trade name Everbond NP 2), an acrylic emulsion-based adhesive, or a contact-type adhesive. Adhesive can be used.

ある。The adhesive non-vulcanized synthetic rubber-based regular sealing material composition further includes an acrylic acid/vinyl alcohol copolymer, a sodium acrylate polymer, a polyethylene oxide,
Water swelling properties can be imparted by blending approximately 10% of a 1-id modified product or other super absorbent polymer. By doing so, the sealing material 4 can more reliably exhibit a water-stopping effect in order to achieve the object of the present invention. That is,
Even if the repulsive force of the foam is insufficient and the sealant cannot reach every corner of the small voids that occur at the interface with the substrate, the rubber layer expands in the presence of water, so High sealing performance is obtained by the expansion pressure. In this case, it is more effective to apply a chloroprene rubber contact type adhesive to the base in advance.
本発明の複合型止水材の全体の厚さは通常目地幅の約2
倍径度のものが好ましい。The overall thickness of the composite waterproofing material of the present invention is usually about 2 times the joint width.
A double diameter one is preferable.

有するのである。With the above configuration, the present invention brings about the following effects. That is, the repulsive force of the foam 1 presses the standard sealant 4 against the underlying surface, so it goes without saying that the sealing effect is high, and since the foam 1 is covered with a weather-resistant vulcanized rubber sheet 2, it will not deteriorate due to aging. It is difficult to remove, maintains repulsive force over a long period of time, and has high durability in terms of adhesion and sealing performance between the standard sealant and the underlying surface.

できるのである。In use, the release paper 5 is removed and then the standard sealant 4 is pasted onto the base 6 due to its self-adhesive properties, or if the joint 7 has already been formed, it is pushed in while removing the release paper. Since it can be simply removed, complicated work processes can be omitted, and it can be easily installed even by specialized craftsmen.
