Description

  The present invention relates to a rubber sac for disaster, and more specifically, a disaster that can improve the stability by suppressing the swelling of the rubber bag body when the water is filled inside, thereby improving the stability. It relates to rubber water sacs.

  Various water sacks have been proposed that are used by filling the inside of a bag body with water instead of a sandbag used to block water in the event of a disaster such as heavy rain or flooding (for example, Patent Document 1). 2). Such a water sac can be easily filled with water through a hose from a water supply or the like, and therefore has an advantage that it requires less labor for preparation than a sandbag.

  However, when a flexible bag body such as a rubber bag body is used, there is a problem that the bag body swells when the interior is filled with water, the shape is not stable, and the stability is lacking. Therefore, the water sac is disadvantageous for stable installation as compared to the sandbag, and needs to be installed carefully so that it does not slip or collapse.

  An object of the present invention is to provide a rubber sac for disaster that can suppress the swelling of the rubber bag body and easily maintain the shape and improve the stability when water is filled therein. is there.

In order to achieve the above object, a disaster rubber sac of the present invention comprises a rubber bag body, and a disaster rubber sac comprising a water injection part and a drain part provided in the rubber bag body. Reinforcing layers are embedded in at least two opposing surfaces, and gripping portions having holes are provided at both left and right ends of the rubber bag body, and engaging portions shaped to fit into the holes protrude from the surface of the rubber bag body. It was set up.

According to the disaster water sac of the present invention, when the reinforcing layer is embedded in at least two opposing surfaces of the rubber bag body, the embedded reinforcing layer becomes a rubber bag when the rubber bag body is filled with water. Since the swelling of the body is suppressed, it is advantageous for maintaining the shape of the rubber bag body. Therefore, it is possible to stably install the rubber sac filled with water at a necessary place. Moreover, it becomes easy to convey a rubber sac by having a holding part.

Here, the gripping portion is formed with the hole in a protruding portion that protrudes from the upper surface of the rubber bag body to the outside of the left and right ends of the rubber bag body, and the engaging portion projects from the upper surface of the rubber bag body. It can also be made to the specifications.

It can also be set as the specification whose said engaging part is the said water injection part or the said drainage part.

The reinforcing layer may be embedded in a surface connecting two opposing surfaces embedded with the reinforcing layer, and the reinforcing layer may be embedded in a ring shape in the rubber bag body. According to this specification, when the rubber bag body is filled with water, the annularly embedded reinforcing layer suppresses the expansion of the rubber bag body, which is more advantageous for maintaining the shape of the rubber bag body. Therefore, the rubber sac can be more stably installed.

The rigidity of the folded surface that is bent and folded when the rubber bag is flattened can be set to be lower than the rigidity of the non-folded surface that is not folded. According to this specification, since the rubber bag body can be easily folded, the work of discharging the water filled in the rubber bag body can be reduced. Moreover, since it becomes easy to make a rubber bag body flat, it becomes convenient for conveyance and storage of a rubber sac.

The volume of the rubber bag is preferably 5000 cm ^{3 to} 40000 cm ³ . According to this specification, even when the inside of the rubber bag is filled with water, the rubber sac can be moved by one or two persons, so that the handling becomes easy.

  Hereinafter, the disaster rubber sacs of the present invention will be described based on the embodiments shown in the drawings.

As illustrated in FIGS. 1 and 2, a disaster rubber sac 1 (hereinafter referred to as a rubber sac 1) serving as a reference embodiment of the present invention includes a rubber bag body 2 and a water injection portion provided in the rubber bag body 2. 7 and a drainage part 8. In this reference form , the shape of the rubber bag body 2 when water is filled therein is a rectangular parallelepiped shape, and a water injection portion 7 is provided on the upper surface 3a and a drainage portion 8 is provided on the lower surface 3b. The rubber bag body 2 can have various shapes such as a cubic shape and a polygonal column shape.

  Examples of the rubber type forming the rubber bag body 2 include natural rubber, styrene / butadiene rubber, chloroprene rubber, EPDM rubber, and blended rubber thereof. In addition, other rubbers such as nitrile / butadiene rubber and synthetic resins such as vinyl chloride resin and urethane resin can be used depending on the purpose. The rubber thickness of each of the surfaces 3a to 3f is, for example, about 1 mm to 10 mm.

  The water injection part 7 is formed of a hard resin or the like, and a part thereof is embedded in the rubber bag body 2 (upper surface 3a), and the lid part 7a protrudes from the surface of the upper surface 3a. When filling the rubber bag body 2 with water, the lid 7a is removed and opened, and a water supply hose such as a water hose or a fire hose is inserted into the opening to fill the water.

  In addition, it is more preferable to install a hose joint such as a one-touch coupler in the water injection part 7 because water can be injected quickly by water pressure or the like.

The drainage portion 8 is formed of a hard resin or the like, and is a recess 4 that is recessed from the surface of the lower surface 3 b of the rubber bag body 2. The drainage part 8 has a shape that fits into the water injection part 7 (lid part 7a) protruding from the surface of the upper surface 3a. When the water filled in the rubber bag body 2 is discharged, the lid portion 8a is removed to open. In addition, the structure of the water injection part 7 and the drainage part 8 is not limited to what was illustrated to this reference form , Other structures can also be employ | adopted.

  Of the surfaces 3a to 3f constituting the rubber bag body 2, the reinforcing layer 6 is embedded only in the two opposing surfaces 3a and 3b. For the reinforcing layer 6, various fiber reinforcing layers such as plain weave canvas and weave cord are used. When the reinforcing layer 6 is not embedded at all in the rubber bag body 2, the surfaces of the surfaces 3a to 3f swell irregularly due to the pressure of the water filled, so that the shape of the rubber bag body 2 is not stable. Therefore, in order to stabilize the shape of the rubber bag body 2, it is necessary to excessively increase the rubber thickness of each of the surfaces 3a to 3f.

On the other hand, when the reinforcing layer 6 is embedded in the two opposing surfaces 3a and 3b of the rubber bag body 2 like the rubber water bladder 1, the embedded reinforcement is filled when the rubber bag body 2 is filled with water. The layer 6 suppresses the bulging of the surfaces 3a and 3b, and accordingly, the bulging of the other surfaces 3c to 3f is also suppressed to some extent. Therefore, it is advantageous to maintain the shape without excessively increasing the rubber thickness of the rubber bag body 2. Since the surfaces 3a and 3b in which the reinforcing layer 6 is embedded can be easily maintained flat, if these surfaces 3a and 3b are formed on the upper and lower surfaces, the water-filled rubber bladder 1 can be stabilized at a necessary place. Can be installed. In the event of a disaster, a large number of rubber sacs 1 are stacked side by side, and if each rubber sacs 1 can be stably installed, the stacked rubber sacs 1 will not easily collapse. Moreover, since it becomes unnecessary to perform installation work paying excessive attention so that the rubber water sac 1 may not collapse, it contributes to speeding up of the installation work.

  2, the surfaces 3a and 3b in which the reinforcing layer 6 is embedded are held flat. Therefore, the surfaces 3c, 3d, 3e, and 3f in which the reinforcing layer 6 is not embedded are used as the lower surface. Can be installed with a certain degree of stability.

  The reinforcing layer 6 only needs to be embedded in at least two opposing surfaces. As illustrated in FIG. 3, the reinforcing layer 6 is reinforced on the surfaces 3e and 3f that connect the two opposing surfaces 3a and 3b in which the reinforcing layer 6 is embedded. The specification can be made such that the reinforcing layer 6 is annularly embedded in the rubber bag 2 so that the layer 6 is embedded and the reinforcing layer 6 is not embedded on the other surfaces 3c and 3d. Or the reinforcement layer 6 can also be embed | buried in all the surfaces 3a-3f which comprise the bag body 2. FIG.

  As illustrated in FIG. 3, when the reinforcing layer 6 is embedded in the rubber bag body 2 in a ring shape, when the rubber bag body 2 is filled with water, the reinforcing layer 6 embedded in the ring shape bulges out of the rubber bag body 2. Suppress. Therefore, it becomes more advantageous to maintain the shape of the rubber bag body 2, and the rubber sacs 1 can be installed more stably. However, when the number of the surfaces in which the reinforcing layer 6 is embedded increases, the weight of the rubber water sac 1 may increase, or the rubber bag 2 may be difficult to fold.

  3 can also be stably installed to some extent even if the surfaces 3c and 3d on which the reinforcing layer 6 is not embedded are the lower surfaces.

  When the rubber bag body 2 is not filled with water and is empty, the rubber bladder 1 can be folded flat by bending the surfaces 3c, 3d, 3e, and 3f as illustrated in FIG. . It is preferable that the surfaces 3c, 3d, 3e, and 3f to be bent and folded have as low rigidity as possible (ease of bending the surface). Thereby, it becomes easy to fold the rubber bag body 2, and it is possible to reduce the labor for discharging the water filled in the rubber bag body 2. Moreover, since it becomes easy to make the rubber bag body 2 flatter, it becomes convenient for conveyance and storage of the rubber sac 1.

  On the other hand, the non-folding surfaces 3a and 3b that are not folded are easy to bulge when the rigidity of the non-folding surfaces 3a and 3b is low and the bag 2 is filled with water. Therefore, it is preferable to set the rigidity of the folding surfaces 3c, 3d, 3e, and 3f, which are bent and folded when the rubber bag body 2 is flat, to be lower than the rigidity of the non-folding surfaces 3a and 3b that are not folded. .

  If the rubber types and the rubber thicknesses of the respective surfaces 3a to 3f are the same, the surface in which the reinforcing layer 6 is embedded has higher rigidity than the surface in which the reinforcing layer 6 is not embedded. Therefore, the level of rigidity can be adjusted depending on whether or not the reinforcing layer 6 is embedded. Or the height of rigidity can be adjusted with the hardness and the number of layers of the reinforcement layer 6 to embed. Of course, the height of the rigidity can be adjusted by changing at least one of the rubber type and the rubber thickness of each of the surfaces 3a to 3f.

Although the water injection part 7 and the drainage part 8 can be provided at arbitrary positions, a load may occur on the surfaces 3a and 3b provided with the water injection part 7 and the drainage part 8 when the lids 7a and 8a are opened and closed. Therefore, it is preferable to provide on the surface where the reinforcing layer 6 is embedded. In this reference form , the water injection section 7 and the drainage section 8 are provided separately, but they can be shared to form one water injection / drainage section.

  As illustrated in FIG. 5, when the rubber sac 1 is stacked, the drainage part 8 of the rubber sac 1 to be stacked is fitted to the water injection part 7 (lid part 7 a) of the rubber sac 1 positioned below. Let Thereby, mutual rubber water sacs 1 can be connected and integrated. Therefore, it becomes difficult for the rubber sac 1 to shift or collapse. Since the water injection portion 8 protruding from the surface of the rubber bag body 2 and the drainage portion 8 formed as a recess are used, there is no need to provide a special protrusion.

As illustrated in FIG. 6, the water injection part 7 and the drainage part 8 can be offset from each other on the upper surface 3 a and the lower surface 3 b. According to this reference form , the rubber sac 1 to be stacked is installed across the two rubber sac 1 positioned below, so that the group of rubber sac 1 to be installed by stacking a plurality of rubber sac 1 is installed. Stability can be improved.

  Not only the structure in which the water injection part 7 and the drainage part 8 are fitted, but also at least one of the water injection part 7 and the drainage part 8 is projected from the surface of the rubber bag body 2 and the projected water injection part 7 or drainage part 8 is provided. What is necessary is just to provide the rubber bag body 2 with the recessed part of the shape to fit. For example, a structure in which a water injection portion 7 is provided on the surface of the rubber bag body 2 and a recess having a shape that fits into the water injection portion 7 is provided at any position of the rubber bag body 2 can be employed.

As illustrated in FIG. 7, in the present invention, gripping portions 5 are provided at both ends of the rubber bag body 2. In this embodiment, holes that allow a hand to enter as the grip portion 5 are formed at both ends of the upper surface 3a. By having the gripping part 5, it becomes easy to transport the rubber sacs 1.

  In this embodiment, the engaging part 9 formed in the shape fitted to the hole of the holding part 5 is provided in the upper surface 3a. Therefore, as illustrated in FIG. 8, when the plurality of rubber sacs 1 are arranged, the gripping portion 5 of one rubber sacs 1 of the rubber sacs 1 adjacent to the left and right is connected to the other rubber sacs 1. By fitting the joint 9, the rubber sacs 1 can be connected to each other. Therefore, it is possible to improve the stability of the group of rubber water sacks 1 installed side by side.

  In the embodiment illustrated in FIG. 9, the gripping portions 5 are provided at both ends of the rubber bag body 2, and the water injection portions 7 protruding from the upper surface 3 a are arranged offset. And the water injection part 7 becomes a shape which fits into the hole of the holding part 5. FIG. Therefore, when arranging the plurality of rubber sac 1, by fitting the gripping part 5 of one rubber sac 1 adjacent to the left and right with the water injection part 7 of the other rubber sac 1, each rubber The water sac 1 can be connected. Therefore, it is possible to improve the stability of the group of rubber water sacks 1 installed side by side. The drainage portion 8 can be protruded from the surface of the rubber bag body 2 and can be fitted into the hole of the grip portion 5.

  The rubber sac 1 is disposed at a predetermined position with the inside of the rubber bag body 2 empty, and then filled with water, or can be pre-filled with water inside the rubber bag body 2 in advance. It can also be installed at a predetermined position. Moreover, not only the rubber water sac 1 of the present invention can be arranged or stacked, but also a normal sand sack can be arranged as appropriate and installed in combination with the sand sack and the rubber water sac 1.

Volume of the rubber bag 2 is, for example, preferably about 5000cm ³ ~40000cm ^3. If it is this volume, even if it is a case where the inside of the rubber bag body 2 is filled with water, the rubber water pouch 1 can be moved by one or two people, so that the handling becomes easy. To move in one of the human power, it is preferable to the volume of the rubber bag 2 to about 5000cm ³ ~20000cm ^3.
