Conventionally, in the construction of joints for concrete products, two uneven socket portions on the joint surface C are used. A joint material made of rubber or foam sponge is inserted, and the joint material is compressed by the weight of the concrete or external force, or the joint gap is filled with mortar or special grout material, or the joint material is is inserted and the joint is pulled and compressed using special metal fittings to prevent water leakage. However, when inserting the joint material, the part where the joint material and concrete adhere may get wet with water,
When mud gets in or the concrete surface is not smooth, it is difficult for the joint material and the concrete to come into close contact with each other, and when uneven settlement occurs on soft ground, the joint surface will be broken and a gap of t''L will be created. It is easy to insert the joint material, and it takes two steps to insert the joint material.
When the joint surfaces are filled with mortar, they tend to crack due to drying shrinkage or peel off due to uneven settlement, and special optical fillers cannot provide sufficient adhesion and are expensive, and special metal fittings ( : Also in the compression of joint filler, there was a drawback that construction C required two labors and was likely to increase costs.

It is characterized by its strong adhesive strength, ability to maintain complete watertightness over a long period of time, and ease of construction.

However, it is made to be adhered with adhesive or adhesive. In addition, as a means for adhering the joint material 3, adhesive or adhesive 4 is applied to the outer surface of the joint material 3 to adhere the protective seal 5, and after the facing joint materials 3, 3 are brought together, the protective seal 5, Possible embodiments include peeling off the joint material 5 and adhering it, or providing a sealed hollow portion 6 within the joint material 3 in order to improve the elasticity and adhesion of the joint material 3.

A joint material 3 is integrally molded onto the joint surface 2 of a concrete IJ-to product such as a manhole when the concrete product is molded. Since the joint material 3, which is an elastic material like rubber, is bonded to each other, the adhesive strength is strong, and since it is a flexible joint material, there is no need for conc IJ-) products to settle unevenly or move after construction. Even if water leakage occurs, the joint material 3 expands and contracts to cope with the problem, so water leakage can be completely prevented.

０When the protective seal 5 is adhered to the outer surface of the joint material 3 to protect it, the joint materials 3, 3 can be protected without mud or water adhering to the adhesive surface.
Workability is good as it is a simple operation of pulling and peeling off the protective seals 5, 5 after bringing them together to ensure complete adhesion.
The joint material 3 is made of elastic rubber to maintain its elasticity, but in order to further increase its elasticity, the inside of the joint material 3 is made of elastic rubber. When the sealed hollow part 6 is provided, the external force applied when the joint material 3 is compressed is replaced as internal pressure in the hollow part 6 and becomes the mutual pressure bonding force of the joint materials 3-3.
It can increase the adhesion force of the adhesive or adhesive 4, and when the joint material 3 is held in a formwork and molded as a single unit, the joint material 3 deforms freely and the mold removal operation is performed. It has the remarkable effects mentioned above, such as being able to smoothly perform
