Description

  The present invention relates to a water stoppage plate for preventing water from entering from the front outside the building opening to the rear inside the opening due to guerrilla downpour and the like, and a waterstop structure using the same.

  In recent years, record guerrilla downpours have been occurring frequently in various places due to abnormal weather caused by global warming. However, in urban areas, roads have been paved in pursuit of the convenience of transportation, etc., so that rainwater that has been rained is hardly absorbed into the ground, and is transported to rivers at a stretch after being guided to sewerage facilities. Processing. Under such circumstances, flooding of rivers is induced, and rainwater, which has lost its transfer destination, blows out from the sewerage facilities to the ground, causing flooding such as flooding under the floor of the building and flooding on the floor.

  Conventionally, in the event of such floods, sandbags were built up at building openings such as entrances and exits of buildings to prevent water from entering the interior of buildings, etc. Takes time and effort. Therefore, it is very difficult to prevent water damage that occurs in a short time, and it is not easy to secure a storage place in normal times because of the bulkiness.

  On the other hand, various techniques have been proposed to provide a water stopping or waterproofing method that can be installed in a short time and with low labor. For example, in Patent Literature 1 (Japanese Patent Application Laid-Open No. 2003-278458), “a waterproof device that prevents water from entering from the entrance of a building or the like when the water is increased, and stands upright on both side walls of the entrance. A pair of grooved posts, a bottom plate buried flat on the floor at the entrance, and a waterproof plate that is inserted into the grooves of the grooved posts at both left and right ends and stacked on the bottom plate in one or more stages In the vicinity of both left and right ends of the waterproof plate, a plurality of fixed handles for fixing the waterproof plate to the grooved columns are provided, and the upper and lower ends of the waterproof plate are watertight so as to be pressed by the weight of the waterproof plate. A waterproof device characterized in that watertight rubber is fixed to the left and right ends of the waterproof plate while being pressed by the fixing operation of the fixed handle while fixing the rubber. "

  Patent Document 2 (Japanese Patent Application Laid-Open No. 2017-160693) discloses that “a substantially rectangular plate member having a front surface and a rear surface and having a thickness, and a plate member attached to an end portion of an upper horizontal portion of the plate member. And a pressing mechanism attached to the base, the base being capable of being displaced outward and substantially upward in a substantially horizontal direction with respect to the base, and protruding rearward of the plate member. The water blocking plate is characterized by the fact that the pressing body presses the inward standing surface of the building opening upward and outward to easily install the water stopping plate on the front or rear surface of the building opening. It can be done.

JP 2003-278458 A JP-A-2017-160693

  However, the waterproof device of Patent Document 1 has a complicated structure, a large number of parts, and a complicated mounting operation, and there is still room for improvement in terms of mounting in a short time and with low labor.

  Further, the waterproof plate of Patent Literature 2 can simultaneously press the inwardly standing surface of the building opening upward and outward in two directions with the pressing body, thereby realizing a high waterproofness of the building opening. However, when the pressing force is excessively applied, a reaction force is generated in a direction facing the front (or the rear) of the building opening in contact with the water blocking plate body, and the direction in which the water blocking plate body separates from the building opening ( When the water blocking board body comes into contact with the front of the building opening, it may move forward. Therefore, there is a need for a water stoppage plate that can prevent such a problem beforehand and can further improve the water stoppage of a building opening.

  These circumstances are of even greater concern because of the urgency of unpredictable natural disasters, such as heavy rainfall and the flooding of rivers that accompany them. It can be said that the proposal of a board is an urgent issue.

  Therefore, the present invention has been made in view of the above problems, has a simple structure with a small number of parts, can be installed almost automatically (automatically) in a short time and with low labor, and can be reliably installed in a building opening. It is an object of the present invention to provide a water stoppage plate that can prevent intrusion of water from the front, which corresponds to the outside, to the rear, which corresponds to the inside, and a waterstop structure using the same.

In order to solve the above problems, the present invention provides:
A waterstop plate for preventing water from entering from the front outside the building opening to the rear inside,
A standing plate-shaped water blocking plate body having an opening contact surface that contacts the front edge or the rear edge of the building opening, and a ground contact surface that contacts the ground.
And a pressing body that abuts an inwardly standing surface of the building opening,
With respect to the inwardly standing surface of the building opening, the pressing body is pressed upward and outward, and the pressing body is pressed forward or backward, and has a pressing and pulling means,
The present invention provides a waterproof plate characterized by the following.

Further, in the above-mentioned waterproof plate of the present invention,

A second surface that is substantially parallel to the first surface and that rotates about the axis of the rotation shaft,
The rotation shaft supports the pressing body swingably through the second surface,
By rotating the first surface about the axis of the fixed rotation axis, the pressing body rotates about the axis of the fixed rotation axis together with the rotation rotation axis, so that the inwardly-standing surface of the building opening faces inward. With the approaching mechanism that presses upward and outward with respect to the water blocking plate body and the pressing body in the front-rear direction, and pulls forward or backward with respect to the inward standing surface of the building opening. It is desirable to do.

  According to the water stoppage plate of the present invention having such a configuration, upward and outward with respect to the inwardly erected surface of the building opening, and, while pressing to the, provided with a pressing portion that can be pulled forward or backward. With this configuration, the waterproof plate can be firmly fixed while being pulled toward the building opening side during installation. The pulling of the water stoppage by the front or rearward traction to the inward standing surface of the building opening is performed almost automatically at the time of installing the water stoppage at the building opening. Does not require attention. In addition, even a woman or an elderly person who has no experience of installing a water stop board and has poor strength etc. can easily install it at an opening of a building by one operation (one action) and perform reliable water stop. Therefore, for example, even if floods such as flooding under the floor or flooding on the floor occur due to flooding of rivers or spouting of rainwater from sewerage facilities due to short-time record guerrilla heavy rain, a water stoppage plate at the building opening can be installed for a short time and low labor. It is possible to reliably prevent water from entering from the front outside the building opening to the rear inside the building opening.

Further, in the above-mentioned waterproof plate of the present invention,
The access mechanism is
It is constituted by arranging a bulging portion on the second surface or the first surface,
By rotating the first surface about the axis of the fixed rotation axis, the rotation axis of rotation is rotated, whereby the second surface is rotated about the axis of the rotation axis of rotation, and the first surface is rotated. It is desirable that a separation distance between the water blocking plate main body and the pressing body in the front-rear direction is reduced by the surface or the second surface riding on the bulging portion.

  In the water stoppage plate of the present invention having such a configuration, the use of the bulging portion allows the access mechanism to have a simple structure. By rotating the first surface with the fixed rotation axis and riding the first surface or the second surface on the bulging portion, the separation distance between the first surface and the second surface can be changed. Along with this, the separation distance between the water-stop board main body and the pressing body is reduced, so that the inward standing surface of the building opening is pulled forward or backward (pulling the water-stop board body toward the building opening side). Can be.

Further, in the above-mentioned waterproof plate of the present invention,
It is preferable that the bulging portion has an inclined surface.

  In the water stopping board of the present invention having such a configuration, the first surface or the second surface is smoothly climbed on the bulging portion, and the front or rear traction (water stopping plate) to the inward standing surface of the building opening is performed. To the building opening side).

Further, in the above-mentioned waterproof plate of the present invention,
It is desirable to have a lock mechanism for preventing the first surface from rotating around the axis of the fixed rotation shaft.

  In the water stopping board of the present invention having such a configuration, the upward and outward pressing on the inwardly standing surface of the building opening and the forward or backward pulling by the pressing and pulling means are generated by the pressing. It can be prevented from being unintentionally released due to force or error, and the installation state of the water stop plate with respect to the building opening can be suitably maintained.

Further, in the present invention described above,
Preventing intrusion of water from a building opening by installing the water stoppage plate according to any one of claims 1 to 5 in front of or behind a building opening using the pressing and pulling means,
The present invention provides a water blocking structure for a building opening.

  According to the water blocking structure of the building opening of the present invention having such a configuration, the water blocking plate of the present invention is in contact with the front edge or the rear edge of the building opening and the ground, Since the inwardly standing surface of the building opening can be pressed upward and outward by the pushing and pulling means, and can be towed forward or backward, the water stop plate can be pulled toward the building opening during installation. , Can be fixed firmly. The pulling of the water stoppage by the frontward or rearward pulling toward the inward standing surface of the building opening is performed almost automatically when the waterstop is installed at the building opening. Therefore, even if flooding such as underfloor flooding or on-floor flooding occurs, the water stoppage plate can be installed at the building opening in a short time and with low labor, and the water blocking plate can be installed from the front outside the building opening to the rear inside. Intrusion of water can be reliably prevented.

1. Outline of Water Stopper 1 An outline of a water stoppage 1 according to an embodiment of the present invention will be described with reference to FIG. FIG. 1 is a schematic diagram illustrating an outline of a water stoppage plate 1 in the present embodiment. As shown in FIG. 1, the water stop board 1 of the present embodiment is configured such that a large amount of water such as a flood generated in the event of an emergency hits the interior of the building opening 81 from the front (the right rear side in FIG. 1) to the rear. (In other words, the direction of the rearward direction X2) toward the front side (the left front side in FIG. 1) is prevented.

  More specifically, examples of the building frontage 81 here include doorways and windows having doors and doors in buildings such as houses and buildings, as well as doorways of external structures, and doorways to underground malls and parking lots.

2. Structure of Water Stopper Plate 1 The water stoppage plate 1 includes a water stop plate main body 3 installed in contact with the building opening 81 and an oscillating body 5 including a pressing body 5A that presses the inwardly standing surface 85 of the building opening 81 ( In the present embodiment, one at each of the left and right end portions above the water blocking plate main body 3) and the pressing and pulling means 7 (the present embodiment) for pressing the rocking body 5 against the inwardly standing surface 85 of the building opening 81. In the form, one at each of the left and right end portions above the water stop plate main body 3), a water stop packing (water stop material) that contacts the front or rear edge 83 and the ground 87 of the building opening 81, Are generally provided. Note that the waterproof packing in the present embodiment is not shown in FIG. 1 because it is provided at a portion that comes into contact with the front edge 83 of the building opening 81 and the ground 87.

  In the following description of the embodiment, the case where the water blocking plate 1 is mainly provided in front of the building opening 81 (for example, outside the entrance of the building) is shown. The same applies to the case where it is provided inside the entrance of a building). However, when there is a possibility that a large water pressure may be applied to the water stop plate 1, the water stop plate 1 is provided in front of the building opening 81 because the water stop plate main body 3 is supported by the edge 83 of the building opening. Preferably.

<Water stop plate body 3>
The water blocking plate main body 3 has an opening contact surface 3A that contacts the front or rear edge 83 of the building opening 81, and a ground contact surface 3B that contacts the ground 87, and has a predetermined thickness. It is a substantially rectangular plate-shaped part.

  Further, the water blocking plate main body 3 may be made of resin or metal, and may be made of a plurality of materials. For example, the main part of the water blocking plate main body 3 may be made of resin, and a metal frame material may be provided on the periphery. It may be a hollow body having at least the opening contact surface 3A and the ground contact surface 3B, and having a cross structure inside.

<Water seal>
Waterproof packing is provided on the opening contact surface 3A and the ground contact surface 3B of the waterstop plate main body 3. In the present embodiment, the opening contact surface 3A is disposed continuously in the height direction Z at both left and right ends, and the ground contact surface 3B is disposed substantially over the entire surface.

  The water-stop packing can be made of a rubber material, a resin material, a resin foam, an air bag, or the like. When a pressing force or water pressure is applied to the water-stop plate 1, the water-stop packing is elastically deformed to receive the pressure, and It has a function as a so-called sealing material or packing for sealing so as not to leak water from between the water blocking plate main body 3 and the edge 83 of the building opening 81. In addition, the waterproof packing may be attached to the edge 83 side of the building opening 81, and it is needless to say that these waterproof packings are not essential components if desired waterproofness can be expected.

<Oscillator 5>
Next, the structure of the oscillator 5 will be described in detail with reference to FIG. 2A, 2B, and 2C are views showing the structure of the oscillator 5, FIG. 2A is a perspective view of the oscillator 5, and FIG. 2B is an oscillator. 5 is a plan view, and FIG. 2C is a cross-sectional view taken along the arrow A shown in FIG.

  The oscillating body 5 is directly connected to a second U-shaped part 15 having a second surface 15 and a surface opposed to the second surface 15, which will be described later, and an inwardly standing surface 85 of the building opening 81 having predetermined elasticity. 5A of the pressing body which comes into contact. Further, the second surface 15 is formed with an insertion hole 10 through which a rotation rotary shaft 11 described later is inserted, and a bulging portion 19 protruding toward the opposite surface forming a U-shaped part. The bulging portion 19 has an inclined surface 21 extending from the second surface 15 to the bulging tip.

  The pressing body 5A is brought into contact with the inward standing surface 85 of the building opening 81 by the pressing and pulling means, and is further pressed and towed. The contact surface is desirably formed of a material having a large coefficient of friction, such as rubber or synthetic resin, in order to easily transmit the pressing force and the traction force without slipping. Furthermore, in order to improve the frictional force and to easily release the excessive force when an excessive pressing force is applied, it is desirable to form the concave and convex shape.

  The bulging portion 19 in the present embodiment is formed integrally with the second surface 15 by drawing a part of the flat second metal surface 15. In the present embodiment, it is desirable to set the height from the second surface 15) in the range of 3 mm to 20 mm, and set the inclination angle of the inclined surface 21 in the range of 5 degrees to 45 degrees. This is preferable because the distance between the water blocking plate main body 3 and the pressing body 5A, which is contracted by the approach mechanism, is made appropriate, and the pressing and traction means can be smoothly operated.

  Further, as described above, in the present embodiment, the bulging portion 19 is formed only on the second surface 15 provided with the substantially U-shaped part. Both may be formed so as to be targeted. By adopting such an aspect regarding the formation of the bulging portion 19, the directionality of the rocking body 5 is eliminated, and the oscillating body 5 can be disposed at either the left or right end above the water blocking plate main body 3 (in other words, It is not necessary to prepare two types of the rocking body 5 separately for the upper left installation of the water blocking plate main body 3 and for the upper right installation.) In the present embodiment, the bulging portion 19 is provided on the second surface 15. However, the same effect can be obtained by arranging the bulging portion 19 on the first surface 13 facing the second surface 15. it can. Therefore, the bulging portion 19 may be provided on either the second surface 15 or the first surface 13, or may be provided on both the second surface 15 and the first surface 13.

  The bulging portion may be formed separately from the second surface 15 and fixed to the second surface 15 by an adhesive, a screw, an engagement, or the like. In this case, the material of the swelling portion can be metal, synthetic resin, rubber, or the like, but a hard synthetic resin having lubricity is most preferable.

  When the bulging portion is formed separately from the second surface 15, for example, the embodiments shown in FIGS. 7 and 8 can be used. 7A and 7B are views showing the structure of the bulging portion 119, FIG. 7A is a front view of the bulging portion 119, and FIG. 7B is a view taken in the direction of arrow B in FIG. FIG. FIG. 8 is a view showing a state in which the bulging portion 119 is fixed to the second surface 115 having a structure capable of fixing the bulging portion 119, and FIG. FIG. 8B is a front view of the second surface 115 in the state, and FIG. 8B is a cross-sectional view taken along the arrow C in FIG.

  As shown in FIG. 7, the bulging portion 119 includes a protrusion 119A and a locking piece 119B. The protruding portion 119A is substantially the same as the above-described bulging portion 19, and has a bottom surface 120 that is in contact with the second surface 115 below. The locking piece 119B is a pair of protruding portions that are folded back while protruding further downward from the bottom surface 120 and opposing (substantially upward) from below to the bottom surface. The distance between the folded ends of the locking pieces 119B formed in a pair is set larger than the opening distance of the opening 116 provided on the second surface 115 shown in FIG. 8, and the locking pieces 119B are elastic. Since it is formed so as to be deformable, the bulging portion 119 is locked and fixed to the second surface 115 by fitting the locking pieces 119B formed in a pair so as to be pushed into the opening 116.

  As shown in FIG. 8, the bulging portion 119 is configured so as to be integrally formed with the second surface 115 by locking and locking a locking piece 119 </ b> B into the opening 116 of the second surface 115. By forming the bulging portion 119 separately from the second surface 115, both materials can be made different, and even if the bulging portion 119 is worn or deformed by the continuous use of the access mechanism, the bulging portion 119 may have a different shape. By performing the operation of reducing the distance between the locking pieces 119B from the locked side, the locking can be easily released, and the replacement can be easily performed for maintenance. Further, by using the bulging portions 119 having different protrusion heights of the protrusion portions 119A, the degree of traction by the approach mechanism can be adjusted according to the situation of the site (the building opening 81).

It can be strongly fixed, and the water stoppage of the water stop plate 1 can be secured.

  More specifically, as shown in FIG. 4, first, the bottom surface 27 </ b> B of the base 27 is oriented downward Z <b> 2 (the pressing / pulling means 7 is connected to the upper portion of the water-stop plate body 3, and the water-stop plate body 3 is actually The operation unit 25 is tilted in the Y2 direction in the state of standing on the ground 87). As a result, the first surface 13 connected substantially parallel to the axial direction of the operation unit 25 rotates in the rotation direction R <b> 1 around the axis of the fixed rotation shaft 9, and further rotates on the first surface 13. 11 rotates in the rotation direction R2.

  The rotation shaft 11 rotates in the rotation direction R2 around the axis of the fixed rotation shaft 9 with the separation distance from the fixed rotation shaft 9 as a rotation radius. The pressing body 5 </ b> A supported by the rotary shaft 11 via the rotary shaft 11 rotates in the rotation direction R <b> 2 around the axis of the fixed rotary shaft 9. That is, the pressing body 5 </ b> A provided in the rocking body 5 performs an operation of moving in the upward Z <b> 1 direction and the outward Y <b> 1 direction with respect to the inwardly standing surface 85 of the building opening 81.

  Since the second surface 15 is supported rotatably (in other words, swingable) at the axis of the rotation shaft 11, the rocking body 5 is configured to include the second surface 15. It is possible to freely change the orientation direction within the range of rotation about the axis of the rotation shaft 11. Therefore, even if the rocking body 5 rotates around the axis of the fixed rotating shaft 9, it can easily face the inwardly standing surface 85 of the building opening 81 together with the pressing body 5A provided therein.

  By the above-mentioned action of the pushing and pulling means 7, the inwardly standing surface 85 of the building opening 81 can be pushed by the pushing body 5A upward Z1 and outward Y1. At substantially the same time as these operations, the pressing body 5A reduces the separation distance from the water blocking plate main body 3 by the pressing and pulling means (approaching mechanism), and is pulled in the forward direction X1 or the backward direction X2. At this time, since the pressing body 5A presses the inwardly standing surface 85 of the building opening 81 and is substantially fixed to the surface, the pressing body 5A becomes a starting point and the pressing and pulling means 7 (approaching mechanism) ) Is drawn toward the building opening 81, the opening contact surface 3 </ b> A of the water stopping plate body 3 and the edge 83 of the building opening 81 come into close contact with each other, and the water stoppage between the two. Can be secured. The specific mechanism that exerts the traction action will be described in detail below.

<Traction of forward X1 or backward X2>
By rotating the first surface 13 about the axis of the fixed rotation shaft 9, the rotation rotation shaft 11 rotates, and thereby the second surface 15 rotates about the rotation rotation axis. Along with this, the first surface 13 or the second surface 15 rides on the bulging portion 19 to reduce the separation distance in the front-rear direction X between the water blocking plate main body 3 and the pressing body 5A (to shorten the separation distance), 5A can be towed in the forward X1 or backward X2 direction.

The operation will be specifically described according to the present embodiment as follows.
When the first surface 13 is rotated about the axis of the fixed rotation shaft 9, the rotation rotation shaft 11 and the second surface 15 (oscillating unit 5) rotate about the fixed rotation shaft 9 in conjunction with the rotation. I do. By this rotation, the pressing body 5A connected to the second surface 15 approaches the inward contact surface 85 of the building opening 81. When the rotation reaches a predetermined rotation angle, the pressing body 5 </ b> A comes into contact with the inward contact surface 85 of the building opening 81. By this contact, the second surface 15 that has been rotated in conjunction with the rotation of the first surface 13 stops rotating. However, as described above, since the second surface 15 and the first surface 13 are supported in a swingable (rotatable) state, the stopped second surface 15 is the first surface 15. With the further rotation of 13, it rotates around the axis of the rotating shaft 11. Then, the first surface 13 and the second surface 15 are in a relationship of rotating with each other about the rotation shaft 11. For this reason, the tip region on the other end side of the first surface 13 rides on the bulging portion 19 provided on the second surface 15, and a force acts in a direction to increase the distance between the first surface 13 and the second surface 15. . As a result, the second surface 15 (the pressing body 5A) reduces the separation distance between the water blocking plate main body 3 in the front-rear direction X (shortens the separation distance), and the pressing body 5A draws the water blocking plate main body 3 to stop. The water plate main body 3 is brought into close contact with the building opening 81 side.

  In addition, since the water stop board 1 can be installed at either the front edge or the rear edge of the building opening 81, the traction direction here is expressed as "forward X1 or rear X2". . Specifically, as in the present embodiment, when the water blocking plate 1 is installed at the front edge of the building opening 81, the pressing and pulling means 7 pulls the pressing body 5A forward X1, and the pressing body 5A Since the water blocking plate main body 3 is fixed to the inward standing surface 85 of the building opening 81, the water blocking plate main body 3 is drawn toward the building opening 81. On the other hand, when the waterproof plate 1 is installed at the rear edge of the building opening 81, the pressing body 5A is pulled backward X2, and the waterproof plate body 3 is drawn toward the building opening 81.

  Further specific examples according to the present embodiment are as follows. That is, before the first surface 13 is rotated about the axis of the fixed rotating shaft 11 by the operation of the operation unit 25, the elastic force of the first spring 31 causes the second surface 15 to move the first surface 13 (actually, the first surface 13). Since the first surface 13 and the second surface 15 are pressed closest to each other (the surface opposite to the plate body constituting the surface 13), the first surface 13 and the second surface 15 are closest to each other (as a relative positional relationship with the water blocking plate body 3) Is located in the direction of the rearward direction X2.), And the distance W between the first surface 13 and the standing surface 27A of the base 27 (the water blocking plate main body 3) is the most distant (particularly, FIG. )), The first surface 13 is rotated about the axis of the fixed rotating shaft 9 by the operation of the operation unit 25, so that the distal end region on the other end side in the length direction of the first surface 13 is on the second surface 15. The second surface 15 rides on the formed bulging portion 19, and the second surface 15 faces forward X1 as a relative positional relationship with the water blocking plate main body 3. By moving the direction, the distance W between the standing 設面 27A (waterstop body 3) of the second surface 15 and the base 27 approaches.

  That is, since the rocking body 5 (the pressing body 5A) having the second surface 15 approaches the standing surface 27A (the water blocking plate main body 3) of the base 27, the pressing body 5A of the rocking body 5 is directed forward. It can be towed in the direction of X1. Note that the distance W gradually decreases as the first surface 13 slides on the inclined surface 21 of the bulging portion 19, and becomes the smallest when the first surface 13 completely rides on the bulging portion 19 ( In particular, see FIG. The distance between the first surface 13 and the second surface 15 can be changed with a simple mechanical structure using the bulging portion 19.

  The above-mentioned pressing of the upward Z1 and the outward Y1 against the inwardly standing surface 85 of the building opening 81 using the pressing and pulling means 7 and the towing of the forward X1 (or the backward X2) are performed in a predetermined direction. Can be achieved almost simultaneously by only one action of defeating Since the water blocking board 1 of the present embodiment includes the pressing and pulling means 7 capable of performing the two-direction pressing and the one-way pulling substantially simultaneously, the water blocking board main body 3 can be easily moved to the building opening 81. In addition, it can be installed without gaps, and can prevent water leakage more.

4. Structure of Lock Mechanism 23 Next, the structure of the lock mechanism 23 will be described in detail with reference to FIG. 6 (a), 6 (b) and 6 (c) are views showing the structure of the lock mechanism 23, and FIG. 6 (a) is a front view of the pressing and pulling means 7 in an enlarged view of the vicinity of the lock mechanism 23. FIG. 6B is a side view of the pressing and pulling means 7, and FIG. 6C is a plan view of the pressing and pulling means 7. The lock mechanism 23 prevents (temporarily fixes) the first surface 13 from rotating (returning back) in the opposite direction after the first surface 13 is rotated to an appropriate angle by the axis of the fixed rotating shaft 9. is there.

  As shown in FIGS. 6A, 6 </ b> B, and 6 </ b> C, the lock mechanism 23 includes a substantially rod-shaped pin body 33 that penetrates a perforation provided in the first surface 13 in a freely insertable state. It is generally constituted by a second spring 35 that presses toward the standing surface 27A side, and an engagement hole 37 that is disposed on the standing surface 27A and engages with the pin body 33.

  The pin body 33 is arranged so as to be oriented in the axial direction so as to be substantially perpendicular to the first surface 13 and to be movable in the front-rear direction X with respect to the first surface 13. The second spring 35 has one end fixed to the pin body 33 while the pin body 33 is inserted therein, and the other end facing the first surface 13 forming a U-shaped part. , The pin body 33 is constantly pressed against the standing surface 27A by the elastic force.

  The engagement hole 37 is a hole that penetrates the standing surface 27A in the front-rear direction X, and preferably has a diameter obtained by adding a predetermined clearance to the diameter of the pin body 33. Further, when the first surface 13 is rotated about the axis of the fixed rotating shaft 9, the pin body 33 is rotated in conjunction with the axis of the fixed rotating shaft 9 when the first surface 13 is rotated about the axis of the fixed rotating shaft 9. The first surface 13 at the rotational position of the first surface 13 (in other words, the position where the pressing body 5A is moved in the above three directions) on the orbit and at which the pressing and traction effect by the above-described pressing and traction means 7 is most obtained. It is desirable that the position be fixed.

  By configuring the lock mechanism 23 as described above, when the water blocking plate main body 3 is installed in the building opening 81 using the pressing and pulling means 7, the rotation of the first surface 13 causes the pin body 33 to engage with the engagement hole 37. Overlaps the position. Since the pin body 33 is pressed against the upright surface 27A by the second spring 35, the pin body 33 is automatically inserted into the engagement hole 37 and both are engaged with each other, and the axis of the fixed rotary shaft 9 is The rotation of the first surface 13 at is fixed.

  A ring-shaped finger hook (hook) is attached to the tip of the pin body 33 on the side opposite to the engagement hole 37. When the water blocking plate 1 is removed (the pressing and pulling means 7 is released), the finger hook is used. By pulling with a finger, the pin body 33 is pulled out from the engagement hole 37 and the locked state can be released. Thus, the rotation state of the first surface 13 at the axis of the fixed rotation shaft 9 is returned to the original state, and the water stop plate 1 can be easily removed from the building opening 81.

  The lock mechanism 23 prevents the pressing and towing means 7 from inadvertently releasing the pressing and towing of the building opening 81 on the inwardly standing surface 85 of the building opening 81 due to a pressing reaction force or the like. 1 can be maintained, and the person who installs the water stop plate can use the sound generated when the pin body 33 is engaged with the engagement hole 37 to cause the first surface 13 to be fixed at the axis of the fixed rotating shaft 9. Since it can be sensed that has been rotated to an appropriate angle, it is possible to appropriately install the water stoppage plate without excessive force.
