In addition, the pair of first order plates A 17 and the first order plates B 18 protruding to both sides of the first blocking plate 11 and the second blocking plate 12 flow out from both concrete structures. Water is prevented from moving along the first blocking plate 11 and the second blocking plate 12, and the bending is formed on the end side of the first order plate A (17) and the first order plate B (18). The portion A 17A and the bent portion B 18A serve to block water flowing out from the sides of the first order plate A 17 and the second order plate 21.

In addition, the second water collecting plate 21 protruding laterally at both ends of the first blocking plate 11 and the second blocking plate 12 serves to block moisture penetrating from the outside of the concrete structure. The bent portion C21A formed at the end side of the 21 serves to block moisture that penetrates from the side of the second order plate 21.

FIG. 3 is an enlarged view of a portion “C” of FIG. 2, wherein the first order plate A 17 and the first order plate B 18 of the present invention as shown in FIG. It is fixed to the first blocking plate 11 and the second blocking plate 12, and the other side is fixed to each side wall portion of the first blocking plate 11 and the second blocking plate 12 by the silicon 19 scanning.

This is due to the specificity of the first order plate A 17 and the first order plate B 18 having a small contact area and a long length with respect to the first blocking plate 11 and the second blocking plate 12. In the case where welding is performed on both sides, warpage of the first order plate A 17 and the first order plate B 18 occurs due to high temperature heat.

Therefore, the first order plate A 17 and the first order plate B 18 of the present invention first scan one side with silicon 19 to the first blocking plate 11 and the second blocking plate 12. After fixing the first order plate A 17 and the first order plate B 18, the other side is fixed by welding. Reference numeral 17A denotes a bend portion C here.

4 is a cross-sectional view showing a connection state of the present invention.

As shown in the drawing, when a plurality of joint apparatuses according to the present invention are used, they are connected to each other by a flange 22 protruding laterally of the first blocking plate 11 and the second blocking plate 12. , Respectively, the first blocking plate 11 and the second blocking plate 12 face each other so that the fastening holes 22A of the flange 22 coincide with each other, and then, the bolt B is inserted into the fastening holes 22A. Are connected to each other by fastening the nut (N).

In addition, as described above, the filling space 13 between the first blocking plate 11 and the second blocking plate 12 is filled with the joint filter 14, and both concrete structures have the first blocking plate 11. And the mutual joint is made by the anchor bolt 16 protruding in both sides of the second blocking plate 12. In addition, the second water blocking plate 21 protruding to the side of the first blocking plate 11 and the second blocking plate 12 serves to block moisture penetrating into the concrete structure from the outside, the second order The bent portion C 21A formed at the end side of the plate 21 serves to block moisture penetrating from the concrete structure side.

5 is a cross-sectional view showing a sealing state of the present invention.

When using a plurality of joints according to the invention as shown in this, the sealing 23 is interposed between them to be kept airtight mutually, the sealing 23 is made of a rubber material excellent in sealing force It is formed and has a structure in which the insertion groove 23A is symmetrically formed. That is, each end side of the first blocking plate 11 and the second blocking plate 12 is inserted into the insertion groove 23A of the sealing 23 so that the first blocking plate 11 and the second blocking plate are inserted. (12) It will be able to maintain the confidentiality between.

And as described above, the bent portion C (21A) formed on the end side of the second water-receiving plate 21 serves to block the water penetrating from both sides of the concrete structure side, the both concrete structure is the first blocking plate ( 11) and the joint bolt is made by the anchor bolt 16 formed on the second blocking plate 12.
