Description

The present invention relates to a waterstop for closing an opening of a building to block water from the outside and preventing water from entering the inside, and to a waterstop that can be installed in the opening more easily and reliably.

In recent years, due to abnormal weather caused by global warming, short-term record guerrilla rainstorms are occurring frequently in various places, but roads are being paved in urban areas, and most of the rainwater that has fallen has fallen. It flows from the sewerage facility into the river at once without penetrating into the ground, and the river overflows or rainwater spouts from the sewerage facility in a short time, causing flood damage such as underfloor inundation and above-floor inundation.

In the event of such a flood, sandbags have traditionally been piled up at building openings such as the entrances and exits of buildings to create impermeable walls to prevent water from entering the inside of buildings, but the sandbags are so heavy that they are piled up. The work required a great deal of time and labor, it was difficult to prevent flood damage that occurred in a short time, and it was not easy to secure a storage place because it was bulky.

Therefore, a dedicated waterstop plate formed according to the shape and dimensions of the building opening such as an entrance / exit may be used, and a more reliable waterstop method is being established. The waterstop is fixed to the opening to close the opening and prevent water from entering. For example, the waterstop is placed inside the opening and is viewed from the inside with respect to the frame constituting the opening. A stretch-type waterstop that stretches and fixes in the horizontal direction is used.

However, a waterstop using such a fixing method can be fixed if the frame constituting the opening is provided substantially parallel to the front to the rear of the opening, but the frame is non-parallel. In that case, the tension does not work in the horizontal direction, and it is not possible to securely fix it. Further, even if the frame forming the opening is formed with irregularities having a certain height, it may not be possible to securely fix the frame.

On the other hand, in Patent Document 1 (Japanese Unexamined Patent Publication No. 2016-204948), a hook is hung on the rear side protruding corner of the frame constituting the opening, and a waterstop plate arranged in front of the frame is connected to the hook. At the same time, an inundation prevention device for fixing the waterstop plate to the opening by pulling both of them in the front-rear direction is disclosed. As a result, it is said that the waterstop can be fixed to the opening even if the frames constituting the opening are non-parallel.

JP-A-2016-204948

However, since the inundation prevention device of Patent Document 1 includes a hook and a mechanical mechanism for pulling the hook as described above, the weight of the device is increased together with the waterstop main body. Therefore, it takes time to move the inundation prevention device to the vicinity of the opening before it is fixed to the opening, and the movement itself is difficult. In addition, it is difficult to ensure that there is no gap between the opening and the main body of the waterstop, and there is a problem that water infiltrates into the building side through the derived gap.

That is, focusing on the structure of the conventional waterstop plate, there is no mechanism for assisting the transportation of the waterstop plate main body, and it is difficult to move the waterstop plate main body to the opening only by the strength of the installer. There was still room for improvement. Therefore, an object of the present invention is to provide a water stop plate provided with a mechanism for urging the water stop plate main body to the opening side so that the water stop plate main body can be easily and surely arranged in the opening.

In order to solve the above problems, the present invention
A waterstop equipped with an urging mechanism that urges the waterstop that closes the building opening to the opening side.
Waterstop body and
Floor contact part and
It is composed of an inclined plate whose inclination angle can be changed with the floor contact portion as a fulcrum.
The floor contact portion is disposed on the bottom surface of one end region of the inclined plate, and the other end is slidably connected to the waterstop in a substantially vertical direction.
To urge the waterstop by further tilting the tilt angle of the tilt plate.
Provide a waterstop characterized by.

In the waterstop plate of the present invention having such a configuration, for example, the installer can step on the inclined plate to apply a treading force from above to below, thereby urging the waterstop main body to the opening side of the building. .. More specifically, in a state where the floor contact portion included in one end region of the inclined plate is in contact with the floor surface, the other end region slides downward by the pedaling force, and the inclined plate slides downward by the pedaling force. Tilt to the surface side. As a result, the other end of the inclined plate emits a urging force toward the opening side with the contact position between the floor surface contact portion and the floor surface as a fulcrum, and the waterstop main body is urged toward the opening side to move. Can be made to.

The configuration of the present invention is preferably applicable to a type of waterstop in which the installer carries the waterstop and places the waterstop on the floor surface of the opening to close the opening. In the water plate, a gap may be created between the water stop plate and the opening side without the installer noticing. In particular, a gap is likely to occur on the lower end side of the waterstop because it is difficult for the installer to see, and if the waterstop is installed as it is, water may leak from between the waterstop and the opening (especially on the lower side of the waterstop). There is. Since the configuration of the present invention can urge the waterstop to move to the opening side, such a problem can be easily and surely eliminated. Further, although it is attempted to further improve the water stopping property by using a padding material (seal material or packing) described later, it functions well when there is a risk of water leakage due to insufficient urging to the opening side.

Further, in the above-mentioned waterstop plate of the present invention, the waterstop plate main body is provided with at least one connecting piece which is erected from the surface of the waterstop plate and has elongated holes extending in a substantially vertical direction, and is inclined. It is desirable that the other end region of the plate be slidably connected along the elongated holes.

In the waterstop plate of the present invention having such a configuration, if the other end of the inclined plate is connected to the elongated hole provided in the connecting piece and slidable along the shape of the elongated hole, the inclined plate is inclined. The operation can be stabilized, and the waterstop body can be urged to the opening side of the building more reliably.

Further, in the waterstop plate of the present invention, the inclined plate is connected to the waterstop plate main body by using a fixture, and the fixture is substantially perpendicular to the fixing surface and the fixing surface. It is composed of connection pieces arranged at both ends of the fixed surface, both of which are provided with elongated holes extending in a substantially vertical direction, and the other end region of the inclined plate is provided along the elongated holes. It is desirable that the fixing surface is slidably connected and the fixing surface is fixed to the waterstop body.

In the waterstop plate of the present invention having such a configuration, a fixture different from the waterstop plate main body can be used for the mechanism for generating the urging force, which facilitates the manufacture of the device and faces the two. Since it has a connecting piece, the slide of the waterstop can be made more stable.

Further, in the waterstop plate of the present invention, the inclined plate is provided with an inclined holding means, and the inclined holding means pulls the other end region of the inclined plate upward or downward. It is desirable that the elastic body performs push-up urging.

In the waterstop plate of the present invention having such a configuration, a treading force is applied by traction urging upward or pushing up the other end region of the inclined plate from below using the inclined holding means. The inclined state of the inclined plate is maintained when it is not. Therefore, when the installer releases the treading force on the inclined plate, the inclined plate can be automatically returned to the original inclined state. Further, by pulling and urging the other end region of the inclined plate upward, one end region is oriented downward, and the floor surface contact portion can be reliably brought into contact with the floor surface.

Further, after applying a treading force to the inclined plate to incline it and urging the waterstop main body to the opening side, the original inclined state of the inclined plate is restored by releasing the treading force, so that one end region of the inclined plate is released. Move to the opening side. Therefore, it is possible to easily and surely close the opening by gradually moving the waterstop main body to the opening side only by repeatedly adding and releasing the pedaling force to the inclined plate.

Further, in the waterstop plate of the present invention, it is desirable that the inclined plate can be rotated and locked with respect to the waterstop plate main body about the other end portion.

In the waterstop plate of the present invention having such a configuration, the inclined plate is rotated toward the waterstop main body side with the other end portion (connection portion with the connecting piece) of the inclined plate as an axis, and the protrusions are connected. By engaging with one of the engaging portions, the inclined plate can be erected substantially parallel to the waterstop main body. This prevents accidents such as a human accidentally catching a foot on the inclined plate when the waterstop is not in use or after the installation in the opening is completed, and it is easier to store it in the storage space when not in use. can do.

Further, in the waterstop plate of the present invention, it is desirable that the floor contact portion has a substantially hemispherical shape protruding downward.

In the waterstop plate of the present invention having such a configuration, the floor contact portion is made substantially hemispherical, and the arc side faces the floor surface so that the contact area between the floor contact portion and the floor surface can be increased. It becomes smaller and can be a more stable fulcrum when the inclined plate is inclined. That is, even if the inclination angle of the inclined plate changes, any point of the substantially spherical floor surface contact portion abuts on the floor surface, and the surface pressure is high in a small area, so that the floor surface does not slip. It can be gripped securely and function as a fulcrum.

According to the present invention, it is possible to provide a waterstop plate provided with a mechanism for urging the waterstop plate main body to the opening side so that the waterstop plate main body can be easily and surely arranged in the opening. Since the urging mechanism is arranged on the lower end side of the waterstop, it is possible to reliably urge the lower end side where a gap is likely to occur and close the space between the waterstop and the opening to eliminate water leakage. can.

At this time, the inclined plate 7 is inclined toward the floor surface 59 along the arc line L1 formed with the contact position between the floor surface contact portion 11 and the floor surface 59 as a fulcrum. Further, as the inclined plate 7 is inclined, the penetration 13 slides downward along the elongated hole 37 of the fixture 9.

As described above, the inclined plate 7 is inclined along the arc line L1 and slides along the elongated hole 37. At this time, the floor surface contact portion 11 (fulcrum) of the inclined plate 7 strongly contacts the floor surface 59 due to the pedaling force, so that the contact position does not change due to slipping or shifting. As a result, the piercing 13 is urged rearward by the component force in the horizontal direction caused by the inclined movement of the piercing 13 along the arc line L1. That is, the fixture 9 and the waterstop body 3 can be pressed toward the opening 51 through the penetration 13. More specifically, since the piercing 13 moves forward and downward along the arc line L1 and the elongated hole 37 with the inclination, the horizontal distance L2 of the piercing 13 before and after the inclination becomes an urging force, and the fixture 9 and the fixture 9 and The waterstop body 3 can be moved to the opening 51 side. At this time, the elastic body 15 is stretched as the penetration 13 moves downward, and the upward traction force of the inclined plate 7 is further increased (see FIG. 6B).

Next, as shown in FIGS. 7A and 7B, the installer releases the treading force on the inclined plate 7 and pulls the inclined plate 7 upward by the elastic force (contracting force) of the elastic body 15. The position of the floor contact portion 11 can be changed as the pedaling force is released, and by pulling the inclined plate 7 upward, the floor contact portion 11 of the inclined plate 7 is opened on the opening 51 side. Since the contact position between the floor surface contact portion 11 and the floor surface 59 is changed, the fulcrum also moves to the opening 51 side.

By repeating the addition and release of the pedaling force described above a plurality of times, the waterstop plate 1 of the present embodiment can be gradually moved toward the opening 51 (the waterstop plate 1 can be moved by a horizontal distance of L2 minutes by applying the pedaling force once). It is possible to surely bring the waterstop main body 3 into contact with the opening edge portion 57. Even if the waterstop body 3 has a weight that is difficult to move easily by force, the installer can safely and easily stop the water by stepping on the inclined plate 7 and applying the weight as described above. The arrangement of the plates can be adjusted (it goes without saying that one stepping force may be sufficient depending on the mounting position of the waterstop plate 1). It goes without saying that in this way, the waterstop plate main body 3 and the opening edge portion 57 are brought into close contact with each other to improve the watertightness. The flexibly formed backing material 61A is elastically crushed by the urging force, and the water stoppage can be further improved. Then, the installer may repeatedly apply the treading force to a certain extent and stop this work in a state where the movement cannot be performed (a state in which the inclined plate 7 does not incline any more even if the treading force is applied).

After adjusting the arrangement of the waterstop plate 1 in the present embodiment by the above procedure, as shown in FIG. 9, the waterstop plate main body 3 is pressed against the floor surface 59 by using the pressing mechanism 63 provided. As the pressing mechanism 63, for example, a mechanism for pressing the waterstop plate 1 disclosed in Japanese Patent Application Laid-Open No. 2017-160693 downward can be adopted. That is, by tilting the operation lever, the fixed rotary shaft to which the rotary shaft core is fixed rotates, and the pressing portion abuts on the opening inner wall 65 in conjunction with the rotation of the shaft, and when the lever is further tilted, Rotational rotation in which the shaft core rotates The rotating shaft rotates, and as a result, the water stop plate main body 3 can be pressed downward (floor surface 59 side) while the pressing portion abuts and presses against the opening inner wall 65.

By moving the main waterstop plate 1 using the urging device 5, the waterstop plate main body 3 is brought into contact with the floor surface 59 and the opening edge portion 57, and then the pressing mechanism 63 is used to bring the waterstop plate body 3 onto the floor surface 59. Press. When activating the pressing mechanism 63, the installer performs the operation in a state where the inclined plate 7 is depressed (a state in which a pedaling force is applied), so that the waterstop plate main body 3 is urged toward the opening 51 side. It is more preferable because it can be pressed and fixed toward the floor surface 59. As a result, the main waterstop plate 1 after the arrangement adjustment can be fixed more firmly, and the opening 51 can be closed easily and surely. Note that FIG. 9 is a schematic view showing a method of fixing the waterstop plate 1 in the present embodiment.

5. Storage of the inclined plate 7 In the waterstop plate 1 of the present embodiment, the inclined plate 7 can be rotated toward the fixture 9 and stored when not in use. A method of storing the inclined plate 7 will be described in detail with reference to FIGS. 8A and 8B. 8 (a) and 8 (b) are views showing a method of storing the inclined plate 7, and FIG. 8 (a) is a schematic showing a state in which the inclined plate 7 is rotated toward the waterstop main body 3. FIG. 8B is a schematic view showing a state in which the protrusion 27 is engaged with the engagement portion 35.

The storage of the inclined plate 7 can be achieved by rotating the inclined plate 7 toward the waterstop main body 3 side as shown in FIGS. 8A and 8B. More specifically, the storage method is rotated so as to flip up one end region of the inclined plate 7 toward the waterstop main body 3 side with the penetration 13 as a fulcrum (one end region of the inclined plate 7 is Rotate so as to move upward), and engage and lock the protrusion 27 with the engaging portion 35 included in the fixture 9. That is, the waterstop plate 1 of the present embodiment has a configuration in which the inclined plate 7 is rotatable and lockable with respect to the waterstop plate main body 3 with the other end as an axis. ..

As described above, since the inclined plate 7 is pulled upward by the elastic body 15 via the penetration 13, the protrusion 27 is pulled upward and the engaging portion 35 and the protrusion 27 are engaged with each other. Is maintained. In this state, the inclined plate 7 is erected substantially parallel to the waterstop plate main body 3 and is in the stored state. By storing the inclined plate 7 in this way, a human accidentally hooks a foot on the inclined plate 7 when the waterstop plate 1 of the present embodiment is not used or after the installation in the opening 51 is completed. It can be stored in the storage space more easily when not in use, while preventing accidents.
