DETAILED DESCRIPTION The following is an explanation about an embodiment of the present invention. V
FIG. 1 is a side view of the whole embodiment showing the state in which the under water structures such as sunk boxes 1, 2, 3, 4, 5 between the shafts A, A and the under water structures are respectively joined water tightly through gaskets.
FIG. 2 through FIG. 4 are diagrams showing the cases in which a joint of the present invention for connecting under water structures is used for water tightly connecting the hollow under water structures. The end portion of said gasket 10 is contacted against the end surface of the other hollow under water structure water tightly connected to each other; the details of said joint are explained in accordance with FIG. 4.
The retaining plate 7 which is made of iron having a projected line 6 extending in parallel with the periphery of the end surface of one of the under water hollow structures 1,2 is fixed on said end surface by means of an anchor reinforcing bar a, and a pressing plate 9 which is made of iron having a plain pressing surface 8 which is fixed on the end surface of the other under water structure by means of the anchor bar b.
is a belt form gasket made of elastic material such as rubber, and is shaped into such a form that the crosssectional view thereof is trapezoidal and the gasket attaching flanges ill are provided on both sides of the base end portion thereof, and the central projected line 12 and the projected lines 13 on both sides are formed on the end surface thereof.
The middle portion of the base end surface of i said belt form gasket 10 is placed in such a manner that said middle portion of the base and surface can be contacted against the projected line 6 of said retaining plate 7 and the belt form pressing member 14 is contacted against the outer surface of said gasket attaching flanges t1, and the T letter from bolt 17 which is engaged against said retaining plate '7 is passed through the bolt holes 11$ and 16 provided through said gasket attaching flanges 11 and the belt form pressing member M, and the gasket attaching flanges ll of the belt form gasket 10 are fixed onto the retaining plate 7 by means of the nut w.
FIGS. 5 and s are the diagrams showing the embodiments in which a joint of the present invention for connectiong under water structures is used for water proof connection of hollow under water structures made of iron, and the only difference between the embodiment of FIG. s and that of FIG. 5 is that in the joint as shown in FIG. 4, the retaining plate 7 and the pressing plate 9 are fixed onto the end surfaces of the adjacent under water concrete structures by means of anchor reinforcing bars a and b, whereas in the joint of FIG. 5, the retaining plate 7 and the pressing plate 9 are respectively welded on the end surfaces of the adjacent under water structures of iron I and 1 Thus, the end surface of the belt form gasket 10 which is fixed onto one 1, of the under water structures is pressed onto the pressing surface 8 of the pressing plate 9 at the end surface of the other under water structure 2 to perform water proof connection.
FIG. 7 is a diagram showing an embodiment of belt form gasket 10, and said belt form gasket has soft rubber layers 21 and 22 wherein the central portions thereof are thicker than the rest, and the hard rubber layer 23 is provided between the respective soft rubber layers 21 and 22, and the three layers are united into one.
When the belt form gasket 10 is formed as described above, it is possible to further improve the stability and water tightness of the belt form gasket 10 when compressed.
FIG. 8 is a diagram showing the belt form pressing member 14, and bolt holes 16 are provided with equal intervals therebetween through said belt form pressing member 14.
FIGS. 9 and 10 are the diagrams showing another embodiment of the joint of this invention, wherein reinforcing metal plates 24 and 25 are fixed on the end surfaces of the hollow under water structures 1, 2 which are made of concrete, and the retaining metal plate 7 having metal rod 26 fixed thereonto extending along the periphery of the end surface, is welded on one 24 of the reinforcing metal plates.
in the same manner as mentioned above, the middle portion of the base end surface of the belt form gasket 10 is placed in such a position that said middle portion can be contacted against said metal rod 26, and supporting metal member 27 which extends along the end surface of the attaching flanges 11 provided on both sides of the base end portion of said belt form gasket 10, are welded on both sides of said retaining plate 7.
Therefore, when said belt form gasket 10 is strongly compressed to exert a great force of expansion onto the base end portion of said gasket 10 so as to widen the width thereof, said great force of expansion is received by said supporting member 27 to prevent the expansion of said gasket 10 throughout the whole length thereof.
28 is a belt form pressing member, and is contacted against the surface of the attaching flanges 11 of the gasket 10, and bolt 30 passing through bolt 29 of the pressing member 28 is engaged into said supporting member 27 to attach said gasket 10 onto said retaining plate 7.
The structure of the joint of the present invention for connecting under water structures, is as described in the foregoing paragraphs, and in accordance with the present invention it is possible to easily carry out water proof connection of the facing end portions of the adjacent under water structures by relatively transferring the under water structures 1, 2 to be connected to each other and by pressing the end surface of one of said under water structures to the end portion of the belt form gasket of the other under water structure, and at the same time, the projected line of the retaining plate is contacted against the middle portion of the base end surface of the belt form gasket, and the central projected line is provided on the end portion of belt form gasket, and therefore the middle portion of the belt form gasket is compressed and strongly pinched, and thereafter the belt form gasket is compressed on both sides thereof, and therefore even when the retaining plate and pressing plate are not in parallel, it is possible to compress the belt form gasket stably by preventing the end of said belt form gasket from being so tilted as to be displaced in the inner and outer directions of the under water structures, and at the same time the groove portion between the central projected line and the projected lines on both sides are pressed onto the pressed surface of the under water structures to be adsorbed, and therefore more accurate water proofness can be attained.
The joint of the present invention for connecting under water structures is of such a structure that the supporting material extending along the end surface of the attaching flanges provided on both sides of the base end portion of the belt form gasket, is united to the under water structure as to which the belt form gasket is fixed as mentioned above, and at the same time a bolt is passed through the belt form pressing member contacted on the surface of the respective attaching flanges, and said bolt is screwed up onto the supporting member, and therefore when the gasket receives great compressive force and great force of expansion for widening the width thereof should be given to the base ends of said gasket, the expansion on the base ends of the gasket can be prevented throughout the whole length thereof by receiving the great force of expansion with said supporting member, and it is possible to attach the gasket without providing the bolt holes on the attaching flanges, and therefore the operation for attaching the gasket can be easily carried out without requiring the adjustment of the positions of the bolt holes of the gasket attaching flanges and belts.
in addition, it is possible to provide the bolts at the position away from the gasket attaching flanges, and therefore when the gasket is compressed, the bolt is contacted against the swollen portion of the gasket to avoid the prevention of the compression, which is accounted to be an advantage.
