を打ち足すよう構成されている。 As shown in Fig. 2, the pouring joint key and water stop device in conventional reinforced concrete structures is installed at the pouring joint 3 of the existing concrete frame portion 31.
2. Two pieces of formwork 33 for the joint key are spaced apart from each other.
The concrete 35 is poured into the formwork 33 to form a pouring key 36, and a water stop plate 37, which is higher than the pouring key 36, is attached to the pouring key 36. When installing the water stop plate 37 on the seam key 36, it is necessary to plant the water stop plate 37 vertically.
A water stop plate holding crosspiece 38 that holds the water stop plate 37 vertically until the concrete 35 hardens is spanned over each formwork 33 and form holding plate 34 to hold the water stop plate 37 between them. After removing the water stop plate 37, the water stop plate 37 is planted and fixed in the concrete 35, and then new concrete is poured onto the existing frame part 31.

At least the formwork holder is not required, and concrete 5 for pouring key is poured between the formworks 3 and 3 for pouring and pouring key, concrete 5 for pouring and pouring key, and concrete 5 for pouring and pouring key and water stopping. The splicing key 6 is formed by fixing the formworks 3, 3 together, and the splicing key/water-stopping forms 3, 3 serve as reinforcement to maintain the strength of the splicing key 6.
The water-stopping property is achieved by using the formworks 3, 3 that are high in the vertical direction, and furthermore, there is no need to dismantle the formworks 3, 3 that serve as joint keys and water stops, and to remove the formwork holder. .

In addition to eliminating the need for a frame holder, the upper part of the formwork 3, 3 for pouring and water-stopping is made to protrude higher than the pouring seam 4 on the upper surface of the concrete 2, and the pouring key and water stopper that also protrudes upward is made. Pour the concrete 5 for the pouring key between the water stop forms 3 and 3, and mix the concrete 2 and the pour key concrete 5 with the pour and water stop formwork 3, 3.
and are fixed together, respectively, and the pouring key 6 is provided to protrude above the concrete 2. Then, new concrete (not shown) is poured onto the pouring joint key 6 and the pouring joint 4 of the concrete 2 to add more concrete. In this case, the two formworks 3, 3 for the pouring key are not dismantled and are integrated with the concrete 2 and the concrete 5 for pouring the pouring key, so that their strength is maintained and they can also be used as a pouring key and water stop. Since the formworks 3, 3 are high and two pieces are fixedly installed, water-stopping properties can be further improved.
