By the way, it is necessary to periodically inspect the road in use for damage to the telescopic device at the joint and the structure around the play space. When performing this inspection work, it is necessary to move above the pier by an aerial work platform, first remove the bolts and holding metal fittings that secure the water stop sheet, and then remove the water stop sheet itself. Also, after completing the inspection work, it is necessary to attach a waterproof sheet and return it to its original state. The work of removing and attaching the water blocking sheet before and after such an inspection takes a considerable amount of time and effort, making it difficult to carry out the inspection work efficiently.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a water blocking device for easily and efficiently performing inspection work of a play space portion.

The water stop device according to the present invention is
It is a water stop device installed in the play space of the seam on the elevated road.
It is equipped with a water-stop sheet that is arranged in a long gutter shape by bending a rectangular sheet into a substantially U shape so that it hangs down across the play space.
The water-stop sheet is formed with a line-shaped opening extending in the length direction of the gutter, and the opening is provided with a waterproof fastener for watertightly closing along the length direction of the opening. be.

According to the water stop device according to the present invention, the gap portion can be clearly seen from below through the opening provided in the water stop sheet without removing the water stop sheet. The work can be performed easily and efficiently. Further, since the opening of the waterproof sheet can be closed watertightly by the waterproof fastener, the waterproofness of the waterproof sheet can be sufficiently ensured at the time of use.

It is a perspective view which showed the state which installed the water stop device by embodiment in the play space. It is a front view which showed the state which installed the water stop device by embodiment (the bellows lid is not shown). It is a figure which showed an example of the waterproof fastener, FIG. 3A is a plan view of the waterproof fastener, and FIG. 3B is a cross-sectional view of the waterproof fastener. FIG. 5 is a side view showing a state in which the opening of the water blocking device according to the embodiment is closed (FIG. 4 (a)) and a state in which the opening is opened (FIG. 4 (b)).

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
As shown in FIGS. 1 and 2, the water stop device 1 of the embodiment is installed in the clearance 22 below the expansion / contraction device 3 installed in the joint 21 of the elevated road 2, and penetrates into the clearance 22 from the joint 21. It receives rainwater, earth and sand, and dust. The water stop device 1 includes a water stop sheet 11 which is arranged in a long gutter shape by bending a rectangular sheet in a substantially U shape so as to hang down over the play space 22. A water blocking material may be installed in the play space 22 at the lower part of the expansion / contraction device 3.

The water-stop sheet 11 is formed of, for example, a rubberized cloth or a tarpaulin coated with a fiber cloth with a resin, has water-stopping property, durability, and flexibility, and is formed from a single rectangular sheet in a non-holding state. Become. The water stop sheet 11 is curved in a substantially U shape and is arranged so as to extend long in a gutter shape, and the both upper edges 11a on the longitudinal side of the gutter shape are supported by the holding metal fittings 12, and the floor slab 23 of the road 2 is supported. It is fixed to the lower surface with a bolt 13. The bolts 13 are attached at a plurality of locations at predetermined intervals over the length direction of the water blocking sheet 11. Since a water leakage prevention material 14 made of rubber, an elastomer or the like is disposed between the upper edge portion 11a of the water stop sheet 11 and the lower surface of the floor slab 23, the water leakage that has flowed into the play space 22 is caused by the water stop sheet 11. It does not leak to the outside from between the upper edge portion 11a and the floor slab 23. In the present embodiment, the water blocking sheet 11 is fixed to the lower surface of the floor slab 23 with bolts 13, but is fixed to the support plate or the like supporting the water blocking material at the lower part of the expansion / contraction device 3 with bolts. It may be in the form.

Further, a semi-circular bellows lid 15 that matches a gutter-shaped substantially U-shape is attached to each end edge portion of the water blocking sheet 11 in the longitudinal direction. The bellows lid 15 closes the edge portion of the waterproof sheet 11 in the longitudinal direction in a watertight manner and can follow the expansion and contraction of the waterproof sheet 11 due to the change in the interval of the play 22.

Further, on the lower surface of the water stop sheet 11, a drainage pipe 16 that penetrates the water stop sheet 11 and extends downward is attached to the vicinity of the end portion in the longitudinal direction. The drainage pipe 16 is made of a flexible member such as rubber, and can be connected to a terminal with a predetermined drainage path. The drainage pipe 16 drains the leaked water that has flowed into the water stop sheet 11 from the play space 22.

By the way, when inspecting the degree of damage to the telescopic device 3 of the seam portion 21 and the structures around the play space 22, conventionally, the water blocking sheet is completely removed from the play space 22 to perform the inspection work, and after the inspection is completed, the inspection work is performed. It was necessary to install the waterproof sheet in its original state. Since it is necessary to remove and attach a large number of bolts 13 and holding metal fittings 12 to remove and attach the water stop sheet, it takes a considerable amount of time and effort, and the inspection work cannot be performed efficiently.

In the water stop device 1 of the present embodiment, the water stop sheet 11 is formed with a line-shaped opening 4 extending in the length direction of a gutter, and the opening 4 is opened with a waterproof fastener 5 for watertightly closing. It is provided along the length direction of the portion 4.

As the waterproof fastener 5, for example, those used for wet suits and the like can be used. For example, as shown in FIGS. 3A and 3B, as a configuration of the waterproof fastener 5, a pair of fastener tapes 51 having waterproofness such as coating an elastomer and opposite ends of each fastener tape 51 are provided. It is provided with a large number of elements 52 attached to the fastener tape 51 and a slider 53 that is slidably attached to the element 52 of each fastener tape 51 to engage and disengage the opposing elements 52. The waterproof fastener 5 is pressed so that the edge portions 54 of the opposing fastener tapes 51 are in close contact with each other by sliding the slider 53 to engage the opposing elements 52, and the edge portion 54 of the fastener tape 51 is pressed. Watertightness and airtightness are surely maintained. Then, the fastener tape 51 of the waterproof fastener 5 is attached to the opening 4 of the waterproof sheet 11 by being watertightly sealed to the peripheral edge of the line-shaped opening 4 by adhesion or welding. Therefore, when the waterproof fastener 5 is closed and the opening 4 is closed, the opening 4 is watertightly closed. The type of waterproof fastener 5 provided on the waterproof sheet 11 is a bislon fastener in which a resin element is injection-molded on a tape, a resin fastener in which the element is formed of a coiled resin, and a metal whose element is a metal. Various things such as fasteners can be used.

From the above, according to the water stop device 1 of the present embodiment, by sliding the slider 53 of the waterproof fastener 5 to open the opening 4 of the water stop sheet 11, the road 2 hidden by the water stop sheet 11 The state of the telescopic device 3 at the seam 21 and the structure around the gap 22 can be seen from below, and the gap 22 portion can be inspected through the opening 4 without removing the waterproof sheet 11. In this case, since the opening 4 is formed in a line shape in the length direction of the gutter shape of the water blocking sheet 11, the opening 4 can be opened in a long and wide range along the length direction at the time of inspection. It is possible to make the 22 portions of the play space easier to see in the length direction. Therefore, the operator can easily perform the inspection work by inserting his / her face or hand into the water blocking sheet 11 through the opening 4. After the inspection is completed, the slider 53 of the waterproof fastener 5 is slid to the original position to close the opening 4 of the waterproof sheet 11, so that the opening 4 is watertightly closed. The rainwater that flows down does not leak from the opening 4, and the waterproofness of the waterproof sheet 11 is ensured. In this way, before and after the inspection work, it is only necessary to operate the waterproof fastener 5 to open and close the opening 4 of the waterproof sheet 11, and it is not necessary to perform time-consuming work such as removing and attaching the waterproof sheet 11. The inspection work can be performed satisfactorily and reliably through the opening 4 of the water blocking sheet 11. Therefore, a series of inspection work in the play space 22 portion can be easily and efficiently performed. Further, the earth and sand and dust accumulated in the water blocking sheet 11 can be easily removed through the opening 4. Therefore, the drainage function of the water blocking sheet 11 can be maintained satisfactorily.

The opening 4 is about 1/10 to about 1/2, preferably about 1/7 to about 2 from the lowest position with respect to the total height of the gutter shape of the water stop sheet 11 on the side surface of the gutter shape of the water stop sheet 11. It is provided at the height position H of / 5. In the embodiment, the opening 4 is provided at a height position H of about 1/7 of the total height of the water blocking sheet 11 (see FIG. 2). The height position H of the opening 4 is provided at the bottom surface region in the water blocking sheet 11 where deposits such as earth and sand are likely to accumulate, that is, at the height position H of the upper part of the U-shaped curved portion of the water blocking sheet 11. Be done. As a result, when the waterproof fastener 5 is slid to open the opening 4, the earth and sand, dust, rainwater, etc. accumulated on the bottom surface of the waterproof sheet 11 are not discharged from the opening 4 at once and fall. .. Therefore, the worker who works from under the water blocking sheet 11 does not get covered with earth and sand, dust, and the like.

The upper edge portion 11a of the waterproof sheet 11 is fixed to the lower surface of the floor slab 23 of the play space 22, but the waterproof fastener 5 corresponds to the height position H of the opening 4 and corresponds to the upper edge portion of the waterproof sheet 11. It is arranged at a position (height position H) away from 11a. Therefore, the operation of the waterproof fastener 5 can be easily performed without the floor slab 23 or the like of the play space 22 getting in the way.

Since the opening 4 is provided along the length direction of the water blocking sheet 11 at the height position H of about 1/10 to about 1/2, when the opening 4 is opened, it is directly below the opening 4. The water-stopping sheet 11 fabric of No. 11 hangs downward due to its own weight to widen the opening 4 (see FIG. 4B), and the wide open state of the opening 4 is stably maintained. Therefore, the operator can easily enter the face and hands into the water blocking sheet 11 through the opening 4. The opening 4 does not close during the inspection and does not interfere with the inspection work, so that the inspection work can be performed smoothly.

As shown in FIGS. 4A and 4B, the opening 4 is provided in two parts on the right side and the left side with the central portion as a boundary in the length direction of the gutter shape. As a result, the waterproof fastener 5 can be easily operated along the length direction even with the long waterproof sheet 11. Therefore, the opening 4 can be easily opened and closed over the length direction of the gutter shape of the water blocking sheet 11. Further, the central portion of the waterproof sheet 11 in the length direction is a non-opening region 17, and the fabric of the waterproof sheet 11 is connected as it is. Therefore, the gutter-shaped shape of the water blocking sheet 11 can be maintained even when the opening 4 is opened.

Further, the slider 53 of each waterproof fastener 5 in each opening 4 on the right side and the left side is provided so as to be arranged on the central portion side when the opening 4 is closed (see FIG. 4A). .. As a result, the position of the slider 53 can be simultaneously confirmed at the central portion of the waterproof sheet 11 as to whether or not each opening 4 is completely closed by each waterproof fastener 5. Therefore, it is possible to prevent the opening 4 from being left in an incompletely closed state after the inspection is completed.

In the present embodiment, the opening 4 is provided only on one side of the two facing surfaces of the gutter shape in the water blocking sheet 11, but both sides may be provided. When the opening 4 is provided on only one side surface, the inspection work of the gap 22 portion can be sufficiently performed from only the opening 4 on this one side surface. Therefore, the formation of the opening 4 and the waterproof fastener 5 for inspection can be kept to the minimum necessary, and the durability of the waterproof sheet 11 is not lowered or the cost is not increased.

As described above, according to the water stop device 1 according to the present embodiment, the gap 22 portion can be satisfactorily viewed from below through the opening 4 provided in the water stop sheet 11 without removing the water stop sheet 11. , The inspection work of the gap 22 portion at the joint portion 21 of the elevated road 2 can be easily and efficiently performed. Further, since the opening 4 of the waterproof sheet 11 can be watertightly closed by the waterproof fastener 5, the waterproofness of the waterproof sheet 11 can be sufficiently ensured during use.

The present invention is not limited to the above embodiment, and modifications can be made as appropriate within the scope of the claims.
For example, each fastener 5 of each of the left and right openings 4 is arranged on the central portion side when the opening 4 is closed, but when one or both of them are closed. It may be arranged on the end side.
Further, the openings 4 are provided separately on the left and right in the length direction of the gutter shape of the water blocking sheet 11, but the present invention is not limited to this, and only one opening 4 extending in the length direction of the gutter shape is provided. May be good.
