Description

The present application relates to an undulating gate and a method for installing the undulating gate.

For example, Patent Document 1 discloses an undulating gate (flap gate) for preventing inundation due to a flood or a tsunami. The undulating gate includes a support portion and a door body whose base end is rotatably supported by the support portion. At the undulating gate, the door body normally touches the ground and lays down, and in an emergency (during flooding), the door body rotates and stands up.

Japanese Patent No. 5580785

By the way, the foundation ground (grounded portion) to which the door body touches the ground when lying down is generally made of concrete, and a certain amount of unevenness is formed on the surface. On the other hand, the lower surface (grounding part) of the door body that touches the foundation ground also has a can manufacturing error (distortion), though not as much as concrete. Then, a partial gap is generated between the door body and the foundation ground at the time of lodging, and the durability of the door body is lowered due to the wheel load of the vehicle that repeatedly acts on the upper surface of the door body. Therefore, in order to reduce the above-mentioned gap as much as possible, it is necessary to perform work such as scraping the convex portion on the surface of the foundation ground, which is very time-consuming.

The technique disclosed in the present application has been made in view of such circumstances, and the purpose is to install a undulating gate and undulation that can reduce the gap between the door body and the ground contact surface at the time of lodging by simple construction. To provide a gate.

The technique disclosed in the present application relates to a method of installing an undulating gate provided with a door body that rotates around a proximal end side to stand up and lie down. The method of installing the undulating gate includes a door body installation process, a panel arrangement process, a panel displacement process, and a panel fixing process. The door body installation step is a step of installing the door body. In the panel arranging step, the panel is brought into contact with the lower surface of the door body by causing the door body to lie down and contacting a plurality of panels forming a grounded surface to which the lower surface of the door body is in contact with the door body when the door body is laid down. This is a step of arranging the doors in a plane so as to be displaceable along the lower surface of the door and at intervals from each other. The panel displacement step is a step of laying down the door body, bringing the lower surface of the door body into contact with the panel, and displace the panel along the lower surface of the door body after the panel arranging step. The panel fixing step is a step of fixing the panel after the panel displacement step.

Another technique disclosed in the present application relates to an undulating gate including a door body and a grounded portion. The door body rotates about the base end side to stand up and lie down. The grounded portions are arranged in a plane shape at intervals from each other, and are provided around a plurality of panels forming a grounded surface on which the lower surface of the door body touches the ground when lying down, and fixes the panels. It has a liquid curing agent.

According to the technique disclosed in the present application, the gap between the door body and the ground contact surface at the time of lying down can be reduced by simple construction.

Hereinafter, embodiments of the present application will be described with reference to the drawings. It should be noted that the following embodiments are essentially preferred examples and are not intended to limit the scope of the techniques disclosed in the present application, their applications, or their uses.

(Embodiment 1)
The first embodiment of the present application will be described with reference to FIGS. 1 to 7. The undulating gate 1 of the present embodiment is installed on the road surface R (land) to prevent water from entering the living space or the underground space due to flood, tsunami, or heavy rain. The undulating gate 1 is a floating undulating gate (sometimes also referred to as a floating flap gate) that automatically performs an upright operation and an undulating operation by using water to enter.

As shown in FIG. 1, the undulating gate 1 includes a door body 10, a support portion 16, and a grounded portion 20. FIG. 1 schematically shows the grounded portion 20. Further, in FIG. 1, water is assumed to enter from the left side.

The door body 10 is formed in a substantially rectangular shape. The door body 10 rotates about the base end 12 side to stand up and lie down. The base end 12 of the door body 10 is rotatably supported by the support portion 16, and the door body 10 rotates from the inverted state so that the tip 11 side stands up. That is, in the undulation gate 1, as shown by an arrow in FIG. 1, the undulation operation is performed by rotating clockwise, and the undulation operation is performed by rotating counterclockwise. The door body 10 is normally in a laid-down state (the state shown by the solid line in FIG. 1), and in an emergency (that is, when water has infiltrated), the door body 10 is rotated from the laid-down state by the buoyancy of the infiltrated water. It is configured to be in an upright state (the state shown by the alternate long and short dash line in FIG. 1).

The door body 10 and the support portion 16 are provided in the storage portion S. The storage portion S is a recess formed in the road surface R, and the door body 10 is stored when the door body 10 is laid down. When the door body 10 is stored in the storage portion S, that is, when the door body 10 is laid down, the lower surface 14 (grounding portion, grounding surface) of the door body 10 is grounded with the grounded surface 23 of the grounded portion 20, which will be described later. On the other hand, the upper surface 13 of the door body 10 is flush with the road surface R (that is, the same height. The same applies thereafter). That is, in a normal state, a vehicle or a person passing through the road surface R will pass through the upper surface 13 of the door body 10.

The grounded portion 20 is provided at the bottom of the storage portion S, and is a portion where the door body 10 touches the ground when lying down. As shown in FIG. 7, the grounded portion 20 includes a frame 21, a panel 22, a raising member 24, an interval holding member 25, and a curing agent 26.

The frame 21 is formed in a rectangular shape in a plan view. The size of the frame 21 in a plan view is substantially the same as the size of the lower surface 14 of the door body 10. A part (substantially lower half) of the frame 21 is embedded in the secondary concrete B2. That is, a part (substantially the upper half) of the frame 21 is exposed from the secondary concrete B2. The secondary concrete B2 is cast on the foundation concrete B1 located at the bottom of the storage portion S.

The frame 21 is a member that defines the ground contact height (falling position) of the door body 10, and the lower surface 14 of the door body 10 touches the ground when the door body 10 falls down. The frame 21 is a rectangular frame in a plan view, and is formed by connecting I (eye) shaped steels in a rectangular shape (see FIG. 5). At the time of lodging, of the lower surface 14 of the door body 10, the lower surface 14 of the tip 11, the base end 12, and the widthwise end is in contact with the upper surface of the frame 21. The frame 21 may be formed of a shaped steel other than the I-shaped steel.

A plurality of panels 22 are provided inside the frame 21, and form a grounded surface 23 to which the lower surface 14 of the door body 10 touches the ground when lying down. The panel 22 is formed in a rectangular shape having a certain thickness. The panel 22 is, for example, a PUF (hard urethane foam) panel. The plurality of panels 22 are arranged in a plane (horizontal plane) at intervals from each other. The upper surface of the plurality of panels 22 arranged in this way becomes the ground contact surface 23. The panel 22 may be made of a material other than the PUF panel.

A plurality of raising members 24 are provided to raise each panel 22 so that a space is formed below the panel 22 when the curing agent 26 is poured around the panel 22. The raising member 24 is provided under the panel 22 when the curing agent 26 is poured.

The space-holding member 25 is a member that is attached between the panels 22 and 22 and holds the space between the panels 22. The space holding member 25 is provided at the center of one side of the panel 22. The spacing member 25 is configured to allow displacement of the panel 22 in the panel displacement process described later. That is, the interval holding member 25 is configured to follow the displacement of the panel 22 described above. The interval holding member 25 is, for example, a sponge member.

The curing agent 26 fixes the panel 22 after being displaced by the panel displacement process. The curing agent 26 is provided around the panel 22 inside the frame 21. The curing agent 26 is poured into the frame 21 in a liquid state, and then cured to fix the panel 22. The specific density of the panel 22 is smaller than the specific gravity of the curing agent 26. The curing agent 26 is a cement-based self-leveling material or the like having high fluidity.

<How to install the undulating gate>
The above-described undulating gate 1 installation method includes a frame installation process, a door body installation process, a panel arrangement process, a panel displacement process, and a panel fixing process.

First, the frame installation process is performed. The frame installation step is a step of installing the frame 21 in the area where the door body 10 touches the ground at the bottom of the storage portion S. As shown in FIG. 2, in the frame installation process, the frame 21 is installed at a predetermined height from the foundation concrete B1.

Specifically, the frame 21 is temporarily fixed at a predetermined height from the foundation concrete B1 and then fixed by the secondary concrete B2. The frame 21 is installed with a substantially lower half portion embedded in the secondary concrete B2 and a substantially upper half portion exposed from the secondary concrete B2. The method of installing the frame 21 is not limited to the above.

Further, in the frame installation process, the portion where the support portion 16 is installed is formed of the secondary concrete B2. The height of the secondary concrete B2 in the frame 21 is lower than the height of the secondary concrete B2 in which the support portion 16 is installed.

Following the frame installation process, the door body installation process is performed. The door body installation step is a step in which the door body 10 and the support portion 16 are installed in the storage portion S. Specifically, as shown in FIG. 3, the door body 10 and the support portion 16 are installed by fixing the support portion 16 to the secondary concrete B2. The base end 12 of the door body 10 is connected to the support portion 16. The door body 10 is installed in a state where the lower surface 14 can come into contact with the upper surface of the frame 21.

Following the door body installation process, a panel arrangement process is performed. The panel arranging step is performed with the door body 10 standing upright. In the panel arranging step, the panels 22 are spaced apart from each other so that the panels 22 can be displaced along the lower surface 14 of the door body 10 by causing the door body 10 to lie down and contact the lower surface 14 of the door body 10. This is a process of arranging in a plane.

Specifically, as shown in FIGS. 4 and 5, in the panel arranging step, first, a plurality of raising members 24 are arranged at predetermined positions. That is, the raising member 24 is arranged on the secondary concrete B2 in the frame 21.

Subsequently, a plurality of panels 22 are arranged on the raising member 24. At this time, the plurality of panels 22 are arranged with the interval holding member 25 attached between the panels 22 and the panel 22. The plurality of panels 22 are arranged in a plane (horizontal plane) at intervals from each other. By arranging the panel 22 on the raising member 24 in this way, a space is formed below the panel 22. That is, the panel 22 is supported by the raising member 24 and is arranged at a distance from the secondary concrete B2.

The raising member 24 supports the four corners of the panel 22. In some places, one raising member 24 supports a plurality of corners. For example, at a position where the four corners of different panels 22 face each other, one raising member 24 is arranged so as to straddle the four corners. Further, at a position where two corners of different panels 22 are adjacent to each other, one raising member 24 is arranged so as to straddle the two corners.

Subsequently, in the panel arranging step, as shown in FIG. 6, a liquid curing agent 26 is poured around the panel 22 to raise the panel 22. That is, the panel 22 is levitated by the buoyancy of the curing agent. The curing agent 26 is poured into the frame 21 until the panel 22 rises to a predetermined height. Specifically, the panel 22 rises to a position where the upper surface (contact patch 23) is higher than the upper surface of the frame 21, that is, until it projects upward from the upper surface of the frame 21.

At this time, since the space is formed below the panel 22 by the raising member 24, the buoyancy due to the curing agent 26 is more likely to act on the panel 22 as compared with the case where the panel is directly arranged on the secondary concrete B2, for example. .. Further, since the interval holding member 25 is provided, the interval between the panel 22 and the panel 22 is maintained, so that it is possible to prevent the panel 22 from being unevenly distributed in one place and floating.

By floating the panel 22 in this way, the panel 22 is in a displaceable state when the lower surface 14 of the door body 10 comes into contact with the panel in the panel displacement step described later.

Following the panel placement step, a panel displacement step is performed. The panel displacement step is a step in which the door body 10 is laid down so that the lower surface 14 of the door body 10 is brought into contact with the panel 22 and the panel 22 is displaced along the lower surface 14 of the door body 10. The panel displacement step is performed until the curing agent 26 is cured.

Specifically, as shown in FIG. 7, the door body 10 is laid down until the lower surface 14 of the door body 10 comes into contact with the upper surface of the frame 21. At this time, since the panel 22 protrudes from the upper surface of the frame 21, it comes into contact with the lower surface 14 of the door body 10 and is pushed down. Then, the panel 22 is displaced along the shape of the lower surface 14 of the door body 10. Since the panel 22 is in a state of floating on the liquid curing agent 26, the panel 22 is easily displaced along the lower surface 14 of the door body 10. As a result, the gap between the lower surface 14 of the door body 10 and the grounded surface 23 (upper surface of the panel 22) is reduced.

For example, the panel 22 of the lower surface 14 where a positive error (distortion) is generated from the design value is displaced as compared with the panel 22 where a negative error (distortion) is generated from the design value. The amount is large. That is, there may be a case where the panel 22 does not come into contact with the portion where the negative error is larger than the design value. Therefore, the buoyancy height of the panel 22 due to the buoyancy of the curing agent 26, that is, the amount of protrusion from the upper surface of the frame 21 of the panel 22, takes into consideration the portion of the lower surface 14 of the door body 10 having the largest negative error than the design value. Is set.

As shown in FIG. 7, for example, when the upper surface of the frame 21 is used as a reference surface corresponding to the design value, a positive error means that the lower surface 14 projects toward the arrow (+) side of the upper surface of the frame 21. A negative error means that the lower surface 14 is recessed on the arrow (−) side of the upper surface of the frame 21.

Following the panel displacement step, a panel fixing step is performed. The panel fixing step is a step of fixing the panel 22 displaced by the panel displacement step. That is, in the panel fixing step, the panel 22 is fixed in a displaced state. Specifically, as shown in FIG. 7, the door body 10 is continuously maintained in a state of being laid down from the panel displacement step. As a result, the panel 22 is maintained in a displaced state. Then, the panel 22 is fixed by curing the curing agent 26 after a lapse of a predetermined time.

In this way, the installation of the door body 10, the support portion 16, and the grounded portion 20 is completed.

As described above, the method of installing the undulating gate 1 of the above embodiment includes a door body installation process, a panel arrangement process, a panel displacement process, and a panel fixing process. The door body installation step is a step of installing the door body 10. In the panel arranging step, the panel 22 is brought into contact with the lower surface 14 of the door body 10 by laying down the door body 10 and bringing a plurality of panels 22 forming a grounded surface 23 to which the lower surface 14 of the door body 10 touches the ground when the door body 10 is laid down. This is a step of arranging the door bodies 10 so as to be displaceable along the lower surface 14 of the door body 10 so as to be spaced apart from each other in a plane shape. The panel displacement step is a step in which the door body 10 is laid down, the lower surface 14 of the door body 10 is brought into contact with the panel 22, and the panel 22 is displaced along the lower surface 14 of the door body 10 after the panel arrangement step. The panel fixing step is a step of fixing the panel 22 after the panel displacement step.

According to the above configuration, the plurality of panels 22 forming the grounded surface 23 to which the door body 10 touches the ground when lying down are displaceably arranged along the lower surface 14 of the door body 10, so that the manufactured door body is manufactured. The grounded surface 23 can be formed along the shape of the lower surface 14 of 10. Therefore, it is possible to reduce the gap between the door body 10 and the contact patch 23 at the time of lying down by simple construction. As a result, the durability of the door body 10 is improved.

Further, for example, even when the secondary concrete B2 is cast at a height lower than the design value, the panel 22 is designed by arranging the panel 22 at a height displaceable along the lower surface 14 of the door body 10. The grounded surface 23 can be formed at a high value. This is the same even when the secondary concrete B2 is placed higher than the design value. In this way, the contact patch 23 can be formed at a predetermined height regardless of the height of the secondary concrete B2.

Further, in the method of installing the undulating gate 1 of the above embodiment, in the panel arranging step, after arranging a plurality of panels 22, a liquid curing agent 26 is poured around the panel 22 to raise the panel 22 and to float the panel 22. Then, the panel 22 is fixed by curing the curing agent 26.

According to the above configuration, since the panel 22 is floated by the curing agent 26, the panel 22 can be easily displaced along the lower surface 14 of the door body 10. Further, since the panel 22 is fixed by curing the curing agent 26, the panel 22 can be easily fixed.

Further, in the method of installing the undulating gate 1 of the above embodiment, a spacing member 25 configured to allow displacement of the panel 22 in the panel displacement process is attached between the panel 22 and the panel 22.

According to the above configuration, since the distance between the panel 22 and the panel 22 is maintained, it is possible to prevent the panel 22 from being unevenly distributed when the panel 22 is floated by the curing agent 26. Therefore, it is possible to form the ground contact surface 23 corresponding to the entire lower surface 14 of the door body 10.

Further, in the method of installing the undulating gate 1 of the above embodiment, in the panel arranging step, a raising member 24 for raising the panel 22 is arranged so that a space is formed below the panel 22, and a plurality of raising members 24 are placed on the raising member 24. Panel 22 is arranged.

According to the above configuration, the buoyancy due to the curing agent 26 is more likely to act on the panel 22 as compared with the case where the panel is arranged directly on the secondary concrete B2, for example. Therefore, the panel 22 can be quickly levitated. In the above embodiment, it is necessary to lay down the door body 10 to displace the panel 22 before the curing agent 26 is cured. However, the time required to displace the panel 22 is shortened by rapidly ascending the panel 22. be able to. In particular, it is effective when a curing agent having a short curing time is used or when the lodging time of the door body 10 is long.

Further, the undulating gate 1 of the above embodiment includes a door body 10 and a grounded portion 20. The door body 10 rotates about the base end 12 side to stand up and lie down. The grounded portions 20 are arranged in a plane shape at intervals from each other, and are provided around a plurality of panels 22 and panels 22 that form a grounded surface 23 on which the lower surface 14 of the door body 10 touches the ground when lying down. It has a liquid curing agent 26 for fixing.

According to the above configuration, the panel 22 can be displaced along the lower surface 14 of the door body 10 by bringing the lower surface 14 of the door body 10 into contact with the panel 22 floated by the liquid curing agent 26. be. Therefore, the contact patch 23 can be formed along the shape of the lower surface 14 of the door body 10, and the gap between the door body 10 and the contact patch 23 at the time of lying down can be reduced.

(Modified Example of Embodiment 1)
In this modification, the configuration of the interval holding member is changed in the method of installing the undulating gate 1 of the first embodiment. Here, the points different from the above-described first embodiment will be described.

As shown in FIG. 8, the interval holding member 27 of the present modification is provided so as to project downward from the lower surface of the panel 22, and also serves as a raising member for raising the panel 22. The spacing member 27 is attached to the lower part of the panel 22. According to this configuration, the arrangement quantity of the raising member 24 can be reduced. Therefore, the time of the panel arrangement process can be shortened.

(Embodiment 2)
The second embodiment of the present application will be described with reference to FIGS. 9 to 12. In the present embodiment, in the above-described first embodiment, the configurations of the panel arranging process, the panel displacement process, the panel fixing process, and the configuration of the grounded portion are changed. Here, the points different from the above-described first embodiment will be described.

As shown in FIG. 12, the grounded portion 30 of the present embodiment includes a frame 31, a panel 32, a plastic member 34, and a curing agent 36. In the grounded portion 30 of the first embodiment, the raising member and the spacing member are omitted, while the plastic member 34 is added to the grounded portion 30.

Similar to the first embodiment, the frame 31 is a rectangular frame in a plan view that defines the ground contact height (falling position) of the door body 10, and the lower surface 14 of the door body 10 touches the ground when lying down. Similar to the first embodiment, a plurality of panels 32 are provided inside the frame 31, and form a grounded surface 33 to which the lower surface 14 of the door body 10 touches the ground when lying down. The plurality of panels 32 are arranged in a plane (horizontal plane) at intervals from each other. The upper surface of the plurality of panels 32 arranged in this way becomes the ground contact surface 33.

A plurality of plastic members 34 are arranged on the secondary concrete B2 inside the frame 31. The plastic member 34 is arranged below the panel 32 and plastically supports the panel 32. The plastic member 34 is configured to be plastically deformed with the displacement of the panel 32 in the panel displacement process. For the plastic member 34, for example, clay is used.

The curing agent 36 fixes the panel 32 after being displaced by the panel displacement process. The curing agent 36 is provided around the panel 32 inside the frame 31. The curing agent 36 is poured into the frame 31 in a liquid state, and then cured to fix the panel 32.

Similar to the first embodiment, the method of installing the undulating gate 1 of the present embodiment includes a frame installation process, a door body installation process, a panel arrangement process, a panel displacement process, and a panel fixing process.

First, the frame installation step and the door body installation step are performed in the same manner as in the first embodiment. In the subsequent panel arrangement step, as in the first embodiment, the panel 32 is displaced along the lower surface 14 of the door body 10 by causing the door body 10 to lie down and contact the lower surface 14 of the door body 10. It is a step of arranging them in a plane with a space between them.

Specifically, as shown in FIGS. 9 and 10, in the panel arranging step, first, a plurality of plastic members 34 are arranged at predetermined positions. That is, the plastic member 34 is arranged on the secondary concrete B2 in the frame 31.

Subsequently, a plurality of panels 32 are arranged on the plastic member 34. The plurality of panels 32 are arranged in a plane (horizontal plane) at intervals from each other. In this way, the panel 32 is supported by the plastic member 34. Further, the panel 32 is supported by the plastic member 34 so that the upper surface (contact patch 33) is higher than the upper surface of the frame 31, that is, protrudes upward from the upper surface of the frame 31.

The plastic member 34 supports the four corners of the panel 32. In some places, one plastic member 34 supports a plurality of corners. For example, at a location where the four corners of different panels 32 face each other, one plastic member 34 is arranged across the four corners. Further, at a position where two corners of different panels 32 are adjacent to each other, one plastic member 34 is arranged so as to straddle the two corners.

Following the panel placement step, a panel displacement step is performed. The panel displacement step is a step in which the door body 10 is laid down so that the lower surface 14 of the door body 10 is brought into contact with the panel 32, and the panel 32 is displaced along the lower surface 14 of the door body 10.

Specifically, as shown in FIG. 11, the door body 10 is laid down until the lower surface 14 of the door body 10 comes into contact with the upper surface of the frame 31. At this time, since the panel 32 protrudes from the upper surface of the frame 31, it comes into contact with the lower surface 14 of the door body 10 and is pushed down. Then, the panel 32 is displaced along the shape of the lower surface 14 of the door body 10, and the plastic member 34 is plastically deformed with the displacement of the panel 32. That is, since the panel 32 is supported by the plastic member 34, it is easily displaced along the lower surface 14 of the door body 10. As a result, the gap between the lower surface 14 of the door body 10 and the grounded surface 33 (upper surface of the panel 32) is reduced.

Also in the present embodiment, as in the first embodiment, the amount of protrusion from the upper surface of the frame 31 of the panel 32 is set in consideration of the portion of the lower surface 14 of the door body 10 having the largest negative error than the design value. NS.

Following the panel displacement step, a panel fixing step is performed. The panel fixing step is a step of fixing the panel 32 displaced by the panel displacement step. That is, in the panel fixing step, the panel 32 is fixed in a displaced state.

Specifically, first, the door body 10 is erected. Subsequently, as shown in FIG. 12, a liquid curing agent 36 is poured around the panel 32, and after a predetermined time, the curing agent 36 cures to fix the panel 32 and the panel 32 does not float.

As described above, in the panel arranging step of the present embodiment, the plastic member 34 is arranged, and a plurality of panels 32 are arranged on the plastic member 34.
