Description

  The present invention relates to a water-stop joint material, and more particularly to a water-stop joint material for water-stopping a joint portion between concrete blocks used as a water channel.

  FIG. 11 is a schematic perspective view showing a state in which a conventional waterproof joint material is attached to a concrete block, and FIG. 12 is an enlarged cross-sectional view of the XII-XII line shown in FIG.

  With reference to these drawings, concrete blocks 15a and concrete blocks 15b whose upper surfaces constituting water channels 18a and 18b are open are installed adjacent to each other through joint portions 16. And the water stop joint material 84 is attached along the joint part 16 so that the joint part 16 may be plugged up from the inner surface. The water-stop joint material 84 has a concave body 88 projecting into the joint portion 16 and a pair of flanges 89a that extend along both longitudinal sides of the concave body 88 and are attached so as to be in contact with the inner surfaces of the water passage 18a and the water passage 18b. It is comprised from the flange 89b.

  When mounting the waterproof joint material 84, the plate-like holding plate 85a and the holding plate 85b that hold the outer surfaces of the flange 89a and the flange 89b are fixed to the concrete block 15a and the concrete block 15b. It is attached via a bolt 90b.

The convex body 36 is connected to the concave body 31, and each of the third flange 37 a and the third flange 37 b is connected to each of the second flange 32 a and the second flange 32 b of the second joint material 34.

  As a result, the waterproof joint material 25 can be easily attached to the upper corners of the water channel 18a and the water channel 18b in the same manner as shown in FIG. 3, and the attached state is stabilized. In addition, since the convex body 36 of the third joint material 39 is formed so as to be directed downward, the attachment state thereof is gravity-stabilized as compared with a shape projecting into the joint portion 16. That is, in such a water channel whose upper part is closed, the water pressure is not applied to the third joint material 39 from the inside because the water channel is not used in a full state.
