When the screw shaft 11 is screwed with the screw hole 53 of the connection fixing shaft 8, the screw shaft 11 moves downward and presses and fixes the tide plate 3 from above via the presser plate 4.
In this state, in addition to the weight of the tide plate 3, the pressing force from the first vertical pressing mechanism 50 acts on the tide plate 3, and the bottom water-stopping rubber 26b is pressed against the ground GL with a strong force. Therefore, water leakage from the bottom of the tide plate 3 is reliably prevented.

On the other hand, in order to move the second front-rear direction pressing mechanism 60 to the tide plate pressing position H2 (FIG. 8), the operation lever portion 64 of the rotation lever 61 is grasped with a hand and rotated about 90 degrees counterclockwise. Thus, the vertical operating lever portion 64 is set to the horizontal posture.
With the operation of the operation lever portion 64, the pressing claw portion 63 originally located outside the recess 27c of the both ends support 41 gradually enters the recess 27c of the both ends support 41, As shown in FIG. 10, the tide plate 3 is moved to the holding surface 28 side by a reaction force in which the tapered portion 62 abuts against the inner wall surface of the outer side plate portion 27 a that is the action surface 29 of the both-end support column 41.

Along with this, the vertical water stop rubber 26a provided at both ends in the horizontal direction X on the rear surface 3e of the tide plate 3 is against the inner wall surface of the inner plate portion 27b which is the holding surface 28 of the both ends support column 41. Since it is strongly pressed, water leakage from the side surface 3f side of both ends of the tide plate 3 is reliably prevented.
Note that the operation order of the first up-down direction pressing mechanism 50 and the second back-and-forth direction pressing mechanism 60 may be first, and the second anteroposterior direction pressing mechanism 60 is attached in the direction in which the tide plate 3 is installed. The front surface 3d side may be directed toward the water entry direction, or the rear surface 3e side may be directed toward the water entry direction.

And according to the tide board apparatus 1A which concerns on such 1st Embodiment, the approach of water with respect to the narrow passage width S to which the passage width S is about 2 m can be prevented effectively, and the rigidity which the tide board 3 has Can withstand high water pressure.
Further, due to the strong pressing force obtained by the first vertical pressing mechanism 50 and the second longitudinal pressing mechanism 60 and the high adhesion obtained by the elastic force of the bottom water blocking rubber 26b and the vertical water blocking rubber 26a. Water leakage between the tide plate 3 and the ground GL and between the tide plate 3 and the both-end support columns 41 and 41 is reliably prevented.
Moreover, since only one tide plate 3 is used for installation, and the weight of the tide plate 3 is light and a handle 3a is provided, the tide plate 3 can be easily transported, installed, removed, and stored. Become. Further, since the structure of the tide plate apparatus 1A is simple and the number of parts is small, the product cost can be reduced.

It is possible to omit the direction pressing mechanism 60 and reduce the number of the second front-rear direction pressing mechanisms 60 installed.

  In addition, it is possible to configure the intermediate strut 31 by combining two sets of both-end struts 41 so that the intermediate plate portions 27d (FIG. 6) are in contact with each other. The height dimensions of the both-end struts 41 and the intermediate struts 31 are not limited to the dimensions described above, and can be variously changed according to the narrowness of the applied passage width S.

  FIGS. 17 to 21 are diagrams showing a third embodiment of the present invention. In each figure, the same parts as those in FIGS. 1 to 16 are denoted by the same reference numerals, and the description thereof is omitted. As shown in FIG. 21, the U-shaped support plate 27 is provided with a horizontal guide groove 27f (each having an engagement groove portion 27g) and an upper end engagement recess portion 27h at each upper portion of the outer plate portion 27a and the inner plate portion 27b. It is done. Reference numeral 81 denotes a third vertical pressing mechanism which is a modification of the first vertical pressing mechanism 50. As shown in FIG. 21, a U-shaped slide plate portion 82 (through the through screw hole 82a on the upper surface and the both side plate portions 82b penetrates). A guide rod 83 that is locked through the through holes 82c of the side plate portions 82b, and a knob 84 (having an operation portion 84a, a screw portion 84b, and a pressing portion 84c). The screw portion 84b is threaded through the screw hole 82a of the slide plate portion 82. In FIGS. 17 and 22, the third vertical pressing mechanism 81 is in the tide plate releasing position V1, the guide rod 83 is engaged with the engagement groove 27g of the guide groove 27f, and the slide plate 82 is provided. Is in the so-called tide plate releasing position V1 that engages with the upper end engaging recess 27h of the support plate 27.

Next, the third embodiment will be described.
As in the case of the first and second embodiments, the operator removes the tide plate 3 from a storage warehouse or the like when an abnormal water increase occurs, and accommodates the U-shaped support plate 27 between the pair of both-end support columns 41, 41. Drop it into the space from above and temporarily mount it. At this time, only the dead weight of the tide plate 3 acts on the ground GL via the bottom water stop rubber 26b.

Next, the third vertical pressing mechanism 81 is moved to the tide plate pressing position V2 (FIG. 8), and then the second longitudinal pressing mechanism 60 is moved to the tide plate pressing position H2 (FIG. 8). Since this operation is the same as that in each of the above embodiments, the description thereof is omitted.
In order to move the third vertical pressing mechanism 81 to the tide plate pressing position V2, the operating portion 84a of the knob 84 in FIGS. 17 and 22 is grasped by hand and slightly lifted upward, then leftward in each figure. Move. Then, the guide rod 83 is disengaged from the engagement groove portion 27g and slides in the same direction while being guided in the guide groove 27f, and reaches the tide plate pressing position V2 (FIGS. 18, 19, and 23). Accordingly, the operation portion 84a is rotated and the knob portions 84b and 82a are screwed together to move the knob 84 downward, and the pressing portion 84c presses the presser plate 4 on the upper surface of the tide plate 3 downward. Thereby, in addition to the dead weight of the tide plate 3, the pressing force from the third vertical pressing mechanism 81 acts on the tide plate 3, so that the bottom water stop rubber 26b is grounded with a strong force as in the above embodiment. The water leakage from the bottom of the tide plate 3 is reliably prevented.

According to the third embodiment, the configuration of the third vertical pressing mechanism 81 is the same as the first vertical pressing mechanism 50, but the relatively long rotating arm 51 rotates while moving in the vertical direction. Compared to what is to be done, it is composed of three small and simple members, a U-shaped plate 82, a guide rod 83 and a knob 84, and the structure is simple, and the operation of the pressing mechanism 81 is relatively short in the lateral direction. Since only the distance slides, the operation is simple, and the cost can be reduced and the apparatus can be downsized.
The configuration of the third vertical pressing mechanism 81 can also be applied to the case where two tide plates 3 are used as in the second embodiment, and three or more tide plates 3 are used. It is obvious that the same can be applied to the case.

  The present invention can be used in the manufacture and use fields of tide plate devices that are installed in the event of abnormal water increase to prevent water from entering, and in particular, it uses a highly rigid and lightweight tide plate to ensure high water tightness and easy It has applicability when it is desired to provide a tide plate apparatus that is inexpensive and easy to install and remove.
