含むゴムなどが挙げられる。BACKGROUND OF THE INVENTION Waterstops are used in the joints of concrete structures to prevent water leakage. In the early days, waterstops were made from iron and copper tapes, which were sometimes crimped to give them more flexibility. A composite of rubber and mild steel plate protruding from the rubber was also used.
Recently, a flexible waterproof with two or more key ribs extending along and protruding from the tape to wedge the tape into the concrete on both sides of the seam to be sealed. Tape-like materials have been used. Such waterproof plates are usually made of rubber, plastic materials, etc., and PVC is the most widely used at present. Even more recently, waterstops of hydrophilic or water-swellable materials have been commercialized and used. These waterstops utilize the ability of the material to expand upon contact with water to prevent the passage of water at joints or discontinuities in concrete structures. Examples of the material used for the water-swellable water blocking plate include a water-swellable polyurethane elastomer, a compound of butyl rubber and bentonite soda, and a rubber containing a water-absorbent resin.

うことは通常困難である。For certain applications, it is desirable to use a water-stop plate made of a non-water-swellable material such as ordinary rubber or soft vinyl chloride and a water-swellable water stop plate. However, it is usually difficult to completely connect the two water blocking plates to prevent the passage of water in the system using the two types of water blocking plates.

塩ビ止水板を使うことができる。One example is deep foundation work in confined areas such as digging pile walls or trenches and then burying concrete. Usually the depressions or protrusions are located in the wall at the location of the foundation or floor slab. Since the walls are made of hardened concrete, it is not easy to install ordinary PVC water blocking plates. Builders are trying to achieve water stoppage by installing a junction and wrapping a PVC waterstop in cast-in-place waterproof mortar. However, this is not a good solution as it relies entirely on the skill of the operator under difficult conditions. Therefore, it is important to develop a complete method of connecting the water-swellable water-stop plate and the non-water-swellable water-stop plate so that each of the two types of water-stop plates can be used in a more suitable place and in a more convenient manner. It can be divided, which is a great advantage. That is, a hydrophilic or water-swellable water stop plate can be used at the junction between the wall and the foundation slab, and a normal external or rear installed PVC water stop plate can be used at the foundation slab itself.

着剤で容易に塩ビと結合できる。Examples of the water-swellable material of the present invention include rubber containing a water-absorbent resin, flexible plastic, and water-swellable polyurethane elastomer. Examples of the water absorbent resin include acrylic acid-based resins such as sodium polyacrylate, carboxymethyl cellulose, polyethylene glycol modified products (urethane modified, epoxy modified, etc.), bentonite soda and the like. Examples of the rubber that serves as the matrix and the flexible plastic include natural rubber, butyl rubber, chloroprene rubber, styrene-butadiene copolymer rubber, and soft vinyl chloride. When a water-swellable polyurethane elastomer is used as the water-swellable material, it is not necessary to use a water-absorbing resin. For example, as the isocyanate, for example, an aliphatic or alicyclic polyisocyanate is used, and a hydrophilic segment (for example, an oxyethylene group) in the chemical structure is used.
Examples thereof include a polyurethane elastomer exhibiting water swelling property. Such a polyurethane elastomer exhibits a stable coefficient of water expansion even in water containing metal ions, and since the rate does not decrease even after long-term immersion, it exhibits an excellent water blocking effect. Examples of such a polyurethane elastomer include Aquaprene (manufactured by Sanyo Chemical Industries). Among such water-swellable polyurethane elastomers, those having a water expansion coefficient of 1.2 to 2.5 times are preferable. These elastomers can be easily bonded to vinyl chloride with a polyurethane adhesive.

There is a water stop plate, and the present invention relates to the water stop plate. Further, the number, shape and placement of the ribs on the tape of non-water swellable material can be optionally varied to suit the design of the waterstop used with the connector.

In the case of the tape-like product, the two types of water-stopping plates, which are water-swellable and non-water-swellable, can be easily connected by heat fusion.
