JP 2001-182027 A

  Since the waterproof protective fence of Patent Document 1 does not use an existing structure (such as a guardrail), a robust structure is required and the cost increases. Moreover, the structure for jumping is complicated, it is easy to break down, and cost becomes still higher.

  This application discloses the water stop structure which can stop water at low cost using the existing guardrail, a collar, etc.

  The present application includes a base end member attached to a support column, a water stop sheet that can be stored / deployed, and a weight. The base end member is attached to one end side of the water stop sheet, and the weight is attached to the other end side. The water stop structure characterized by being attached is disclosed.

FIG. 1 shows a water stop structure 10 according to an embodiment of the present invention. FIG. 2 shows the water stop structure 10 as viewed from above. FIG. 3 shows the waterstop structure 10 in a stored state in cross section. FIG. 4 shows the waterstop structure 10 in a developed state in a cross section. FIG. 5 shows the shape of the mounting member 11. FIG. 6 shows the shape of the proximal member 12. FIG. 7 shows a water stop structure 10A of another embodiment. FIG. 8 shows a water stop structure 10B of another embodiment. FIG. 9 shows a water stop structure 10C of another embodiment.

  1-4 shows the water stop structure 10 using the guardrail 1. FIG. The guard rail 1 includes, for example, a plurality of support columns 2 standing on a road shoulder (ground) and the like and a guard plate 3 supported by the support columns 2.

  The water stop structure 10 includes a mounting member 11, a base end member 12, a water stop sheet 13, a weight 14, and a binding member 15.

  The mounting member 11 is a member for attaching the proximal end member 12 to the column 2. FIG. 5 shows an exemplary mounting member 11. The mounting member 11 in this figure has a ring 11 a that can be mounted on the support 2, a fixture 11 b such as a bolt, and two engagement protrusions 11 c that engage the base end member 12.

  The proximal end member 12 is supported by the support column 2 via the mounting member 11. FIG. 6 shows an exemplary proximal member 12. The base end member 12 in the figure has a rod-like main body 12a and engagement holes 12b at both ends thereof. Although a cylindrical body 12a is shown, other shapes are possible. The engagement hole 12b may have a shape complementary to the engagement protrusion 11c. When the engagement protrusion 11c and the engagement hole 12b have a non-circular (for example, polygonal) cross section, the base end member 12 is held in a non-rotatable manner, and the waterproof sheet 13 can be easily folded. Providing the engagement hole 12b penetrating the main body 12a may reduce the weight of the base end member 12.

  The water blocking sheet 13 is a sheet-like member that can be expanded / stored. The waterproof sheet 13 may be made of polyethylene, vinyl, or the like having improved water resistance, weather resistance, or the like. The water stop sheet 13 of this example is stored in a foldable manner. The base end member 12 is fixed to one end side 13a of the water-stop sheet 13, and the weight 14 is fixed to the other end side 13b. The fixing method may be any method such as caulking, scissors, bolts, adhesive, and sewing as long as it can be prevented from coming off firmly. The water-stop sheet 13 has a width dimension (for example, a length of several to several tens of columns 2) sufficient to cover the total extension that requires water-stop. The vertical dimension of the water stop sheet 13 is sufficiently longer than the height H (FIG. 3) of the one end 13a.

  The weight 14 is a member having a weight sufficient to deploy the water-stop sheet 13. The weight 14 is conveniently a sand bag. The weight 14 may have the same length as the width dimension of the waterproof sheet 13. The length may be approximately the same as the base end member 12. A number of shorter weights (for example, blocks) may be attached at regular intervals.

  The bundling member 15 is a member that holds the waterproof sheet 13 in a stored state. Although the string-like binding member 15 is shown in the figure, other forms such as a bag may be used. The string shape is convenient because it is easy to cut. The bundling member 15 is preferably a member having high environmental resistance and high tensile strength, such as synthetic fiber and wire.

  During normal times, the water stop sheet 13 is stored as shown in FIG. Folding at the time of storing may be performed manually, or may be performed by pulling a lifting / lowering cord like a blind (pleated screen or the like). At the time of water increase, by unbundling the bundling member 15, the water-stop sheet 13 can be developed by the weight 14 as shown in FIG. For example, if the binding member 15 is cut, the binding can be quickly released.

  In the water stop structure 10, the existing guard rail 1 can be used to provide water stop simply and inexpensively, and since the bundling of the bundling member 15 is simply released, the water can be stopped quickly and there is little fear of failure. Since the guardrail 1 has sufficient strength, it can withstand high water pressure. Since the mounting member 11 and the base end member 12 are separate and assembled, attachment work to the guard rail 1 is very easy. The mounting member 11 and the base end member 12 may be a single member. The water stop structure 10 may be attached to the guard rail 1 of a river or a road along the sea where water stoppage is highly necessary, but may be another place.

  FIG. 7 shows a water stop structure 10A of another embodiment. The water stop structure 10 </ b> A is different from the water stop structure 10 in that the water stop sheet 13 is stored by being wound around the base end member 12. In order to facilitate winding and expedite deployment, the base end member 12 may be rotatable with respect to the mounting member 11. In this case, the engagement protrusions 11c and the engagement holes 12b may have a circular cross-sectional shape.

  FIG. 8 shows a water stop structure 10B of another embodiment. The water stop structure 10 </ b> B is different from the water stop structure 10 in that the water stop structure 10 </ b> B is attached to the roof 5 of the house 4 or the like using the mounting member 17 instead of the guard rail 1. Thus, the water stop structures 10, 10A, 10B can be attached to various existing structures. The structure, shape, and the like of the mounting member 17 may be adapted according to the shape of the flange 5 and the like.

  FIG. 9 shows a water stop structure 10C of another embodiment. The water stop structure 10C is a water stop point in that the base end member 12 is attached to a plurality of second support columns 16 standing on the road shoulder (ground) or the like at equal intervals or unequal intervals in the longitudinal direction of the road. Different from the structure 10. Therefore, existing structures such as the guardrail 1 are not required. However, as shown in the figure, it is preferable to install the water stop structure 10C along (adjacent to) the guard rail 1, and it can be supported by the guard rail 1 even if the second support column 16 falls down due to the water pressure at the time of water increase. Increases nature.

  The components of the water-stopping structure described in the above embodiment and the dimensions, shape, arrangement, number, material, and the like are examples, and other modes are possible.

  The water stop structure of the present invention provides water stop for floods, high waves, tsunamis, increased water, etc., and can protect houses and towns.
