Description

  The present invention is intended to block water at a predetermined position in a space such as a house, a building, a subway, an underground road, etc. so that water does not flow in from the space on the open floor surface such as an entrance when flooding. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water blocking device which can be easily installed even on an existing structure.

  As a conventional water blocking device, there is one having a structure in which a water blocking plate is assembled so as to be able to move up and down, for example, by excavating a floor surface at an entrance of a building or the like. However, this type of water blocking apparatus is generally a large-scale equipment, and extensive installation is required to install it at the entrance of an existing building or the like. Therefore, in addition to being able to easily install the applicant at the entrance of a building, recently, the applicant does not take space for storage when not in use, and the handling at the time of assembly and dismantling is convenient. A water blocking device has been proposed (see, for example, Patent Document 1).

  The water blocking device described in Patent Document 1 is formed in advance on a floor plate member fixed by screwing in by interposing a packing in a middle of a screw hole previously formed on a floor surface, and a wall surface opposite to a structure. Water retention is fixed to the floor plate member and the left and right post members by screwing left and right post members fixed by interposing the packing in the middle to the screw hole and screwing the screw into the floor plate member and left and right post members It consists of a plate and can be easily installed at the entrance of a building, etc. by a simple screw tightening operation.

Patent No. 5749824

  However, the water blocking device described in Patent Document 1 requires a floor plate member in addition to the support member for the installation of the water blocking plate, and moreover, in order to attach the floor plate member to the floor surface, a large number of screw holes in the floor surface There is a risk that the aesthetics of the floor surface may be impaired.

  The present invention has been made focusing on the above-mentioned problems, and it is possible to reduce the number of parts without requiring a floor plate member to install a water blocking plate, and to form an aesthetic appearance by forming a large number of screw holes in the floor surface. It is an object of the present invention to provide a water shut-off device that is not likely to cause

  In the water blocking device according to the present invention, the right and left support members fixed in a watertight state to the wall surfaces of opposing structures on the floor surface, and the water stopping plates in which both side end portions are fixed in a watertight state to each support member And left and right screws which are screwed into supporting substrates respectively provided at upper positions of the support members and which press both end portions of the water blocking plate from above. On the lower end face of the water blocking plate, a packing which is compressed and deformed by depression of the water blocking plate to make a watertight state between the water blocking plate and the floor surface is fixed over the entire length.

  In the water blocking device having the above configuration, when the side end of the water blocking plate is pressed downward by screws at both positions of the left and right support members, the water blocking plate is pressed and the packing is compressed and deformed over the entire length. There is a watertight condition between the water blocking plate and the floor surface.

  The support substrate of the preferred embodiment integrally includes a vertical plate portion fixed to the wall surface and a horizontal plate portion having screw holes penetrating vertically and projecting upward of the side end portion of the water blocking plate. The screw is screwed into the screw hole of the horizontal plate until the packing is compressed and deformed by the depression of the water blocking plate.

  In this embodiment, when a screw is screwed into the screw hole of the horizontal plate of the support substrate from above, the tip of the screw protrudes downward of the horizontal plate and abuts on the upper surface of the side end of the water blocking plate. As a result, the water blocking plate is pressed and the packing is compressed and deformed over the entire length, so the water blocking state between the water blocking plate and the floor surface becomes watertight.

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

  In the water blocking board of this embodiment, the upper end edge is reinforced by the upper frame material, and the upper frame material is further reinforced by the flange to enhance the mechanical strength of the water blocking board. The flange of the upper frame material plays the role of a handle at the time of assembly and disassembly, and the flange can be used to carry the water blocking plate or carry it on hand.

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

  According to this embodiment, since the water blocking plate is fixed to the column member by screw operation, installation and dismantling of the water blocking plate is easy, and the water blocking plate can be fixed in a watertight state to each column member.

  Another water blocking device according to the present invention further includes a locking and fixing mechanism provided on at least one of the front side and the rear side of the central portion of the lower end portion of the water blocking plate. The locking mechanism includes a fixing base, a screw and an anchor member embedded in the floor surface. The fixed substrate integrally includes a vertical plate portion fixed to the water blocking plate and a horizontal plate portion having a through hole penetrating vertically and located above the floor surface. The screw is inserted into the through hole from above, and has a screw shaft that protrudes downward from the horizontal plate and a head that is supported on the horizontal plate. The screw shaft portion is screwed into the screw hole of the anchor member until the head presses the horizontal plate portion to compress and deform the packing.

  According to the water blocking device of the present invention, when the pressing force of the screw is applied to both side ends of the water blocking plate, if the total length of the water blocking plate is long, sufficient pressing force is exerted on the central portion of the water blocking plate. Although the central portion is floated, since the stopper fixing mechanism is provided, the horizontal plate portion of the stopper fixing substrate fixed to the water blocking plate is pressed down by the head of the screw. As a result, there is no floating of the central portion of the water blocking plate, the packing is compressed and deformed over the entire length, and a watertight state is obtained.

  In addition, in each above-mentioned structure, a "screw" means the external thread which has a screw thread in an outer peripheral surface, and a bolt, a machine screw, a screw, etc. are included. Also, "packing" refers to a filling for keeping water tight, and here refers to a natural rubber, an artificial rubber, a foamed resin, a leather, etc. that can be enhanced in water tightness by compressive deformation.

  According to the present invention, since the floor plate member is not used to install the water blocking plate, the number of parts is reduced, and the appearance of the floor surface is not likely to be deteriorated by forming a large number of screw holes in the floor surface.

A horizontal plate portion located above the floor surface is integrally provided, and the screw is inserted into the through hole from above and supported on the horizontal plate portion and a screw shaft portion which protrudes downward of the horizontal plate portion The screw shank is screwed into the screw hole of the anchor member until the head depresses the horizontal plate to compress and deform the packing .

In the water blocking device having the above-described configuration, when a screw is screwed into the screw hole of the horizontal plate portion of each support substrate from above at the upper position of the left and right support members , the tip of the screw protrudes below the horizontal plate portion Abuts the top of the side edge of the water blocking plate. As a result, the water blocking plate is pressed and the packing is compressed and deformed over the entire length, so the water blocking state between the water blocking plate and the floor surface becomes watertight. When pressing force with screws is applied to both ends of the water blocking plate, if the entire length of the water blocking plate is long, sufficient pressing force does not act on the central portion of the water blocking plate and the central portion floats However, since the locking and fixing mechanism is provided, the horizontal plate portion of the fixed substrate fixed to the water blocking plate is pressed by the head of the screw. As a result, there is no floating of the central portion of the water blocking plate, the packing is compressed and deformed over the entire length, and a watertight state is obtained.
