Description

  This invention is for damming water at a predetermined position in a space such as a house, a building, a subway, and an underground passage so that water does not flow from a space on an open floor such as an entrance and exit during a flood. In particular, the present invention relates to a water stop device that can be easily installed even on an existing structure.

  As a conventional water stop device, there is a structure in which a water stop plate is assembled so as to be able to rise and fall, for example, by excavating a floor surface at an entrance of a building. However, this type of water stop device generally requires a large amount of equipment, and a large amount of construction is required to install it at an entrance of an existing building. Therefore, the applicant can be easily installed at the entrance and exit of a building recently, and saves space when not in use, and is convenient to handle when assembling and dismantling, and can respond quickly to floods. Proposed a water stop device (see, for example, Patent Document 1).

  The water stop device described in Patent Document 1 is formed in advance on a floor plate member that is fixed by screwing a screw in between a screw hole that is formed in advance in the floor surface and a wall surface facing the structure. The left and right column members fixed by screwing the screws in between the screw holes in the middle and the bottom end edge and both side edges fixed to the floor plate member and the left and right column members by screws. It consists of a plate and can be easily installed at the entrance of a building by a simple screw tightening operation.

Japanese Patent No. 5749824

  However, the water stop device described in Patent Document 1 requires a floor plate member in addition to the support member for the installation of the water stop plate. Moreover, in order to attach the floor plate member to the floor surface, many screw holes are provided on the floor surface. It is necessary to form, and there is a risk of damaging the aesthetics of the floor surface.

  The present invention has been made paying attention to the above-mentioned problems, and does not require a floor plate member to install a water stop plate, can reduce the number of parts, and has a beautiful appearance by forming a large number of screw holes on the floor surface. It aims at providing the water stop apparatus which does not cause a fall of water.

The water stop device according to the present invention is fixed in a watertight state to the left and right column members fixed in a watertight manner to the wall surfaces of the opposing structures on the floor surface, and both side end portions to the concave grooves extending over the entire length of each column member. A horizontal plate that has a vertical plate portion that is provided at an upper position of each column member and is fixed to the wall surface, and a screw hole that penetrates up and down and protrudes above the side end portion of the water stop plate. And a left and right screw that is screwed into a screw hole formed in a horizontal plate portion of each support substrate and presses both side ends of the water stop plate from above, and the water stop A packing that is fixed to the lower end surface of the plate over the entire length and is compressed and deformed by pressing the water stop plate with the screw to make a watertight state between the water stop plate and the floor surface, and a central portion of the lower end portion of the water stop plate including a stopper fixing mechanism provided on at least one of front side and rear side of the They are out. The stop fixing mechanism includes a fixed substrate, a screw, and an anchor member embedded in the floor surface, and the fixed substrate has a vertical plate portion fixed to the water stop plate and a through-hole penetrating vertically. And a horizontal plate portion located above the floor surface. The screw is inserted into the through hole from above and protrudes downward from the horizontal plate portion and is supported on the horizontal plate portion. The screw shaft portion is screwed into the screw hole of the anchor member until the head presses the horizontal plate portion and the packing is compressed and deformed .

In the water stop device having the above-described configuration, when a screw is screwed from above into the screw hole of the horizontal plate portion of each support substrate at the upper position of the left and right support members , the tip of the screw protrudes below the horizontal plate portion. It hits the upper surface of the side edge of the waterstop. As a result, the water stop plate is pushed down and the packing is compressed and deformed over the entire length, so that the water stop state is established between the water stop plate and the floor surface. When pressing force with screws is applied to both sides of the water stop plate, if the total length of the water stop plate is long, the center portion will float without sufficient pressure being applied to the center portion of the water stop plate. However, since the stop fixing mechanism is provided, the horizontal plate portion of the fixed substrate fixed to the water stop plate is pushed down by the head of the screw. As a result, there is no floating at the center of the water stop plate, the packing is compressed and deformed over the entire length, and a watertight state is obtained.

  In a preferred embodiment, the water stop plate includes an upper frame member attached along the upper edge. The upper frame member is integrally provided with a top plate portion along the upper end surface of the water stop plate and side plate portions along both front and back surfaces of the upper end edge of the water stop plate, and the top plate portion is provided with a flange.

  In the water stop plate of this embodiment, the upper end edge is reinforced by the upper frame member, and the upper frame member is further reinforced by the flange, so that the mechanical strength of the water stop plate is increased. The flange of the upper frame member plays the role of a handle at the time of assembly or disassembly, and can carry the waterstop or carry it by hand with the flange.

  In a preferred embodiment, each strut member has a plurality of screw holes formed in one of the opposing side plate portions of a frame member having a groove having a groove width larger than the thickness of the water blocking plate over the entire length. Both side ends of the water stop plate are located in the recessed grooves of the respective column members, and the screw holes are inserted into the respective screw holes until the packing interposed between the other side plate portion of each column member and the water stop plate is compressed and deformed. The water stop plate is pressed by the tip of the screwed screw.

  According to this embodiment, since the water stop plate is fixed to the support member by the screw operation, the water stop plate can be easily installed and disassembled, and the water stop plate can be fixed to each support member in a watertight state.

  In each of the above-described configurations, “screw” means a male screw having a thread on the outer peripheral surface, and includes a bolt, a small screw, a screw, and the like. Further, “packing” means a stuffing for keeping watertightness, and here refers to a material whose watertightness is enhanced by compression deformation, such as natural rubber, artificial rubber, foamed resin, and leather.

  According to the present invention, since the floor plate member is not used to install the water stop plate, the number of parts is reduced, and there is no possibility that the appearance of the floor surface is deteriorated by forming a large number of screw holes on the floor surface.
