Description

  The present invention relates to a technique for constructing a structure using a box-type sandbag.

  Box sandbags are sometimes used to construct simple structures. For example, a box-type sandbag is used when a temporary building or a defensive wall must be created immediately on the battlefield.

  Box sandbags usually have three or more side walls. In general, the upper and lower surfaces of the box-type sandbag are open, and the contents enclosed in the space surrounded by the side walls are filled with the contents so as to function as a simple wall. The contents are generally procurable locally, for example, earth and sand, crushed stone, rock, gravel, concrete, or a mixture thereof, or a bag of these. As a result, the box-shaped sandbag can protect against direct fire power such as rifle bullets and rocket bullets, or curved fire power such as cannonballs, and functions as a sufficient protective wall.

The main function of the box-type sandbag is to make a wall as described above. However, a roof may be required depending on the structure.
However, it is difficult to make a roof with a general box sandbag whose upper and lower surfaces are open. In particular, in a structure used in the battlefield, it is necessary to withstand attacks from above, so that the strength of a simple roof may be insufficient.

  This invention makes it the subject to make it possible to construct | assemble the structure with a strong roof using a box-type sandbag.

In order to solve the above-mentioned problems, the present inventor proposes the following invention.
The following inventions are roughly divided into two, the first invention and the second invention, for convenience.
The first invention includes at least four side walls rotatably connected to adjacent ones at its left and right edges, and has an internal space for filling contents that is rectangular when viewed in plan. A box-type sandbag that can be made, and is arranged as appropriate, and the interior space is filled with the contents, so that a wall surrounding the indoor space with an opening can be made. A large number of wall sandbags, and roofing material that is a plate passed over the wall body so as to cover the upper part of the indoor space made of the wall sandbags, and the left and right edges thereof are adjacent to each other At least four side walls that are rotatably connected to each other, so that an internal space for filling the contents that is rectangular when viewed in plan can be created, and is arranged as appropriate And filling the interior space with the contents, A box-shaped sandbags adapted capable of creating a roof covering the top of the timber, comprising and a large number of sandbags roof, a structure-building set.
This set for constructing a structure includes a large number of wall sandbags that are rectangular in plan view, and a wall body can be made by arranging them appropriately and filling the contents in the wall sandbag. Up to here, it is not different from the conventional one.
The structure construction set includes a roofing material. A roof can be made by passing it over a wall made of wall sandbags.
In addition, the structure construction set includes a large number of roof sandbags that are rectangular in plan view, and the roof sandbags are appropriately arranged on the roof material and filled with the contents in the roof sandbags. The material can be reinforced. The wall sandbag that constitutes the wall body may be the same as the conventional box sandbag, but the conventional box sandbag is filled with the contents so that it has sufficient strength to withstand bullets. can get. By arranging the roof sandbags having the same structure on the roofing material, the structure made using the structure construction set of the first invention has a wall sandbag with an open top and bottom surface and a roof sandbag. Although it uses sandbags, it has a roof and not only a roof, but the strength of the roof is sufficient.
Note that both the wall sandbag and the roof sandbag included in the structure construction set can be rectangular in plan view. By using both in the shape of a rectangular shape in plan view, it is possible to arrange them vertically and horizontally without any gap, with the exception of the opening of the wall body made of the sandbag for walls. The absence of a gap ensures the safety of a person in an indoor space in a structure made by the structure construction set, a vehicle placed in the indoor space, and the like. Note that the wall sandbag and the roof sandbag may have other shapes in plan view as long as they can have a rectangular shape in plan view. The same applies to the case of the second invention.

The second invention includes at least four side walls rotatably connected to adjacent ones at its left and right edges, and has an internal space for filling contents that is rectangular when viewed in plan. A box-type sandbag that can be made, and is arranged as appropriate, and the interior space is filled with the contents, so that a wall surrounding the indoor space with an opening can be made. A large number of wall sandbags, and an interior plate made of the wall sandbag, an internal plate for creating a space with a ceiling, and its left and right edges can be rotated with respect to adjacent ones At least four sidewalls connected to each other, and can form an internal space for filling the content that is rectangular when viewed in plan, and is arranged as appropriate so that the internal space Filling the contents into the wall body and the It is to have a box-type sandbags to become capable of creating a roof covering the upper parts plate material, comprising and a large number of sandbags roof, a structure-building set.
Similar to the structure construction set of the first invention, the structure construction set of the second invention includes a number of wall sandbags that are rectangular in plan view, and is arranged as appropriate in the wall sandbag. A wall can be made by filling the contents.
Further, the structure construction set includes an internal plate material for creating a space with a ceiling inside the indoor space made of the wall sandbag.
In addition, the structure construction set includes a large number of roof sandbags that are rectangular in plan view. By arranging them appropriately and filling the contents in the roof soil, the wall body and the inner plate material are provided. A roof that covers the top can be made.
By providing the same roof body as the wall body, the structure made by the structure construction set of the second invention also uses a wall sandbag and a roof sandbag whose upper and lower surfaces are open, In addition to having a roof and a roof, the strength of the roof is sufficient.
Note that both the wall sandbag and the roof sandbag included in the structure construction set can be rectangular in plan view. The advantages of this are the same as in the case of the first invention.

  Although common to the first invention and the second invention, the height of the roof sandbag may be lower than that of the wall sandbag. By doing so, the roof sandbag can be prevented from becoming excessively heavy when the contents are filled in the roof sandbag.

Both the structure construction set of the first invention and the second invention may include a pile that penetrates the wall body up and down and whose tip is driven into the ground. By using such a pile, the wall body made of the sandbag for walls can be fixed to the ground. As a result, it is possible to increase the strength such as rigidity of the structure made of the structure construction set.
The wall sandbag may be stacked in a plurality of stages. In this case, the pile may be configured to penetrate the piled wall sandbag up and down, and the tip of the pile is driven into the ground. Accordingly, it is possible to avoid the upper-stage wall sandbags that are stacked in a plurality of stages from being displaced from the lower-stage wall sandbags.
The upper end of the pile may be flush with the upper end of the wall body regardless of whether or not the wall sandbags are stacked in a plurality of stages. By doing so, in the case of the first invention, the roof material or the roof material and the weight of the roof sandbag placed thereon can be received by the pile, and in the case of the second invention, the wall Because the weight of the wall sandbag on the body (at least a part of it on the pile) can be received by the pile, the wall sandbag constituting the wall body is overweight. As a result, it is possible to reduce the possibility of problems occurring in the wall.

In the second invention, the internal plate member may be a container having an opening that can correspond to the opening of the wall body. This is convenient because existing materials can be used to make structures. Note that “can be made to correspond to the opening of the wall” means that the original purpose of the opening of the container and the opening of the wall is achieved because the opening of the wall is for people or vehicles to enter and exit. It means that they are overlapped to the extent that they are not overlapped.
In addition, the entire inner plate may have a substantially bowl-like shape, and an opening that can correspond to the opening of the wall body may be formed on one side before and after the inner plate member. The internal plate material can be constituted by, for example, a liner plate. The meaning of “can correspond to the opening of the wall” is not different from the above case.
When the internal plate material has a substantially bowl-like shape, a filler that fills the space between the indoor space and the internal plate material may be filled on the internal plate material that has a substantially bowl-like shape as a whole. In that case, there is a possibility that the force that the filling is about to spread from the inner plate material having a substantially bowl-like shape may be applied to the wall bodies on both sides of the inner plate material. . In order to resist such force, the structure is stabilized when there is a first connecting member for connecting the sandbags for walls located on both sides of the internal plate material. The structure construction set of the second invention may be provided with such a first connection member.
When the inner plate has a substantially bowl-like shape, and when using a filler, as described above, a force is applied to the wall members on both sides of the inner plate to spread them on each other. There can be. In order to resist such force, if there is a second connecting member for connecting the wall sandbag located on both sides of the internal plate and the roof sandbag on the wall sandbag, the structure is stabilized. Such a second connection member may be provided in the structure construction set of the second invention.
When the inner plate has a substantially bowl-like shape, and when using a filler, as described above, a force is applied to the wall members on both sides of the inner plate to spread them on each other. There can be. In order to resist such force, a roof material which is a plate passed over the wall body to cover the upper part of the indoor space made of the wall sandbag, and walls located on both sides of the internal plate material If there is a third connecting member that connects the sandbag to the roof material on the sandbag, the structure is stabilized. Such a roof material and a third connection member may be provided in the structure construction set of the third invention.

The inventor of the present application proposes the following method as an example of the invention that produces the same effects as the structure construction set of the first invention.
The method comprises at least four side walls rotatably connected to adjacent ones at its left and right edges, creating an internal space for filling the contents that are rectangular when viewed in plan. A process of creating a wall body that surrounds an indoor space with an opening by appropriately arranging a large number of wall sandbags that are box-shaped sandbags that can be filled, and filling the interior space with contents, the wall A process of covering the upper part of the indoor space made of sandbags with a roof material which is a plate passed over the wall body, at the left and right edges thereof, at least 4 connected rotatably to the adjacent ones A large number of box-type sandbags that are lower in height than the wall sandbags, which have a side wall and are capable of creating an interior space that is rectangular when viewed in plan. Arrange the roof sandbags as appropriate, and fill the internal space with the contents. By, process of making the roof covering the top of the roofing material, includes a method for constructing a structure.

The inventor of the present application proposes the following method as an example of the invention that produces the same effects as the structure construction set of the second invention.
The method comprises at least four side walls rotatably connected to adjacent ones at its left and right edges, creating an internal space for filling the contents that are rectangular when viewed in plan. A process of creating a wall body that surrounds an indoor space with an opening by appropriately arranging a large number of wall sandbags that are box-shaped sandbags that can be filled, and filling the interior space with contents, the wall In the interior space made of sandbags, the process of creating a space with a ceiling with an internal plate material, with at least four side walls connected to the adjacent ones at the left and right edges of the interior A large number of roof sandbags, which are box-type sandbags that are lower than the wall sandbags, can be made as appropriate when creating a rectangular interior space when viewed in plan. And filling the contents into the internal space And the wall body, the process of making the roof covering the top of the inner plate member includes a method for constructing a structure.

  The following contents are applicable to both the first invention and the second invention. In addition, the box-type sandbag described below (the box-type sandbag described below can include both the wall sandbag and the roof sandbag of the present application) are all the features that appear in the first invention and the second invention. It can be applied to box sandbags.

The box-type sandbags of the first and second inventions include at least four side walls rotatably connected to adjacent ones, and the interior for filling contents that is rectangular when viewed in plan A space can be created, and a wall body surrounding the indoor space having an opening can be created by arranging the space appropriately and filling the internal space with the contents.
The side walls of these box-type sandbags are rectangular metal meshes that are configured to include a plurality of vertical bars that run up and down and a plurality of horizontal bars that run to the left and right, in the same way as conventional box-type sandbags. is there.
And these box-type sandbags are a horizontal bar or vertical bar to which a vertical bar or horizontal bar at a specific edge, which is at least one edge of four edges of at least one of the side walls, is attached. It may be attached to both sides.
The box-type sandbags of the first invention and the second invention, particularly the box-type sandbags constituting the wall body, may be stacked. When such stacking is performed, there is a possibility that the lowermost box-type sandbag of the box-type sandbags may be deformed, or the upper-stage box-type sandbag may not be stable with respect to the lower-stage box-type sandbag. It is possible.
In order to solve such a problem, the box-type sandbag of the first invention and the second invention is arranged in a vertical direction at a specific edge which is at least one edge of four edges of at least one of the side walls. A bar or bar may be attached to both sides of the bar or vertical bar to which it is attached.
If the specific edge is the left and right edges of the side wall, the side wall becomes strong against the load in the vertical direction. Moreover, in order to make a specific edge, for example, it is only necessary to add one vertical bar to the left and right edges of a general wire mesh. Therefore, such a box sandbag is considerably stronger than a typical box sandbag, whereas its manufacturing cost is much higher than the manufacturing cost of a general box sandbag as a whole. It will not be.
Further, when the specific edge is the upper and lower edges of the side wall, the side wall is less likely to slip with respect to the lower box-type sandbag. The reason why the conventional upper box sandbag is not stable with respect to the lower box sandbag is that the lower edge of the side wall of the upper box sandbag and the upper side of the side wall directly below the lower box sandbag. Line contact (or the longitudinal direction of both edges) with a certain line segment in the longitudinal direction of both edges, which are both horizontal bars (usually metal bars having a circular cross section including vertical bars) This is because when the directions do not completely match, only point contact is performed. Therefore, the lower edge of the upper side wall of the box-type sandbag is slippery with respect to the upper edge of the lower side wall immediately below it. On the other hand, when the specific edge is the upper and lower edges of the side wall, the lower edge of the side wall with the upper box sandbag and the upper edge of the side wall immediately below the lower box sandbag. The contact can be changed to a line contact with two lines (which is close to a surface contact). Thereby, when box-type sandbags are stacked, it is possible to prevent the upper-stage box-type sandbag from becoming unstable. And the cost required to add such improvements to the sidewalls is not very high.

The specific edge is at least one of the four edges of at least one of the side walls as described above. Of course, the specific edge may be included in all the side walls. For example, the specific edge may be at least one edge of all side walls.
Two or more specific edges may be included in a certain side wall.

  For example, the specific edge may be a left or right edge of the side wall. In this case, when the box-type sandbags are stacked, the possibility that the lowermost box-type sandbag is deformed is further reduced. This effect is greatest when the left and right edges of all side walls are specific edges.

In the construction method of the structure of the first invention and the second invention, when there is a portion in which the box-type sandbags are stacked, the box-type sandbags are stacked in order to reduce the possibility of deformation in the lowermost box-type sandbag. The following method may be adopted for the portion.
The method includes at least four rectangular wire meshes that are configured to include a plurality of vertical bars that run up and down and a plurality of horizontal bars that run to the left and right, which are rotatably connected to adjacent ones. A plurality of box-type sandbags with the same shape and size when viewed in plan are stacked in multiple layers, with the contents being placed in a space surrounded by the side walls. This is a method of constructing a structure. In this method, vertical bars at specific edges, which are the left and right edges of all the side walls, are attached to both sides of a horizontal bar to which they are attached, in at least the lowermost box-type sandbag among the stacked ones. Use things.
At this time, you may make it use what does not have a specific edge in any side wall for the box-type sandbags other than the bottom-most box-type sandbag of what is piled up. The more specific edges, the greater the cost of materials and processing, though not as large, but by using an upper sandbag other than the bottom box sandbag, Such an increase in cost can be reduced.

For example, the specific edge may be the upper and lower edges of the side wall. In this case, when the box-type sandbags are stacked, it becomes easier to stabilize the upper-stage box-type sandbag. This effect is greatest when the upper and lower edges of all side walls are specific edges.
When the specific edge is the upper or lower edge of the side wall, for example, the upper or lower edge of all the side walls, the pin may be included in the structure construction set of the first and second inventions of the present application as follows. good.
In this case, for constructing the structure, two or more box-type sandbags having the same shape and size as viewed in plan, the upper and lower edges of all side walls being specific edges, and the box-type sandbags are stacked. When stacked vertically, the gap between the horizontal bars at the lower edge of the upper box sandbag and the gap between the horizontal bars at the upper edge of the lower box sandbag are stacked together. A structure construction set having a pin that penetrates. With this structure construction set, the horizontal bar at the lower edge of the upper box sandbag and the horizontal bar at the upper edge of the lower box sandbag, which are adjacent to each other by the pin, can be fixed by the pin. Therefore, when box-type sandbags are stacked, the upper-stage box-type sandbag becomes more stable. There may be a plurality of pins. For example, if pins are prepared as many as the number of side walls of the box sandbag, the horizontal bars on the lower edge of the upper box sandbag and the upper edge of the lower box sandbag are adjacent to each other. Since the space between the bars can be fixed with a pin for all the lower edges of the upper box sandbag, the upper box sandbag becomes more stable. Further, pins may be prepared so that a horizontal bar at the lower edge of the upper box sandbag adjacent to each other and a horizontal bar at the upper edge of the lower box sandbag can be fixed by a plurality of pins. Of course, the upper box means that the horizontal bar at the lower edge of the upper box sandbag and the horizontal bar at the upper edge of the lower box sandbag, which are adjacent to each other, are fixed by a plurality of pins. It may be done for all the lower edges of the sandbag.
The pin may be bent into a substantially U shape at its upper end. The pin is used in a U-shaped state with the bottom open, and one end of the pin is a gap between the horizontal bars at the lower edge of the upper box-type sandbag, and the horizontal bar at the upper edge of the lower box-type sandbag. If the other end is exposed to the front side of the box-type sandbag, the upper and lower box-type sandbags are fixed by the pin as long as there is no force to lift the pin. It is not done, and the upper and lower box-type sandbags can be released simply by lifting the other end, which is convenient when removing the box-type sandbags. The lengths of one end and the other end of the pin may be different. For example, one end of the pin may be longer than the other end.

In the construction method of the structure of the first invention and the second invention, when there is a portion where the box-type sandbag is stacked, in order to stabilize the box-shaped sandbag, the following method is applied to the portion where the box-type sandbag is stacked. It may be adopted.
The method includes at least four rectangular wire meshes that are configured to include a plurality of vertical bars that run up and down and a plurality of horizontal bars that run to the left and right, which are rotatably connected to adjacent ones. A plurality of box-type sandbags with the same shape and size when viewed in plan are stacked in multiple layers, with the contents being placed in a space surrounded by the side walls. This is a method of constructing a structure. And in this method, a horizontal bar at a specific edge, which is the upper and lower edges of all the side walls, is attached to both sides of a vertical bar to which it is attached in at least a two-stage box-shaped sandbag from the bottom. Is used.
In this method, the gap between the horizontal bars at the lower edge of the upper box sandbag, and the horizontal edge at the upper edge of the lower box sandbag, of the two box sandbags from the bottom are adjacent to each other. It may include a process in which the gap between the rods is put together with a pin. As for the number and shape of the pins, the same idea as already described for the structure construction set can be adopted. For example, in the above method, the gap between the horizontal bars at the lower edge of the upper box sandbag that is adjacent to each other in the two-stage box sandbags from the bottom, and the upper side of the lower box sandbag. It may include a process in which the gaps between the horizontal bars at the edges of the edges are collectively penetrated with pins.

Further, the inventor of the present application is a rectangular wire mesh that includes a plurality of vertical bars that are rotatably connected to adjacent ones and a plurality of horizontal bars that run left and right. A plurality of box-shaped sandbags having at least four side walls, the upper and lower sides of which are opened and used by putting the contents in a space surrounded by the side walls, and having the same shape and size when viewed from above. A method of removal is also proposed. And in this method, as the box-type sandbag, a horizontal bar at a specific edge, which is an upper and lower edge of all the side walls, is used which is attached to both sides of a vertical bar to which it is attached, and When removing the box-shaped sandbag in which the contents are placed in the space surrounded by the side walls, the box-shaped sandbag is removed by suspending all the specific edges on the upper side with a plurality of hanging tools.
When the box sandbag is removed, a method is used in which the box sandbag is lifted by a predetermined hanging tool (for example, a plurality of hanging tools attached to a removal tool attached to the tip of a crane wire). . If the box-type sandbag is removed in this way, the box-type sandbag has no bottom, so that the contents contained in the box-type sandbag remain there, and only the box-type sandbag can be quickly removed. However, when the box-type sandbag is removed by such a method, the horizontal bar present on the upper edge of the box-type sandbag may be damaged. If the upper edge locked to the hanging tool when hanging is a specific edge, the horizontal bar on the upper edge of the box sandbag can be prevented from being damaged, so the hanging tool can be removed quickly. Even if the hanging method is used, there is little possibility that the repeated use of the box sandbag will be hindered.

  The box sandbags having at least one specific edge on at least one of the side walls, which can be applied to the first invention and the second invention, have four specific top / bottom / left / right sides. It may be an edge. In this case, the specific edge may be four edges of all the side walls.

Hereinafter, preferred first to second embodiments of the present invention will be described.
In the description of each embodiment, common objects are denoted by common reference numerals, and overlapping descriptions are omitted in some cases.

≪First embodiment≫
In the first embodiment, a method of constructing a structure using a structure construction set will be described.
The structure construction set includes a wall sandbag 100, a roof material 200, and a roof sandbag 300. In this embodiment, there is one roof material 200, and a large number of wall sandbags 100 and roof sandbags 300 are included.

First, the structure of the wall sandbag 100 will be described.
A wall sandbag 100 is shown in FIG. In FIG. 1, the display of vertical bars and horizontal bars, which will be described later, is partially omitted.
The wall sandbag 100 has four or more side walls 110. The side wall 110 is shaped and sized so that at least a rectangle can be formed by connecting adjacent edges. Both the upper and lower sides of the wall sandbag 100 are open. When the wall sandbag 100 is used, the contents are packed into an internal space that is a space surrounded by the side walls 110. The contents are, for example, earth and sand, reeds, rocks, a mixture thereof, or a bag of these.
Although not limited to this, the sandbag 100 of this embodiment has four side walls 110. Therefore, the wall sandbag 100 can be a quadrangle in plan view.
Each side wall 110 is rectangular. Each side wall 110 is connected to the adjacent side wall 110 at its left and right edges. This connection is such that each side wall 110 can rotate relative to the left and right edges of adjacent side walls. This is to enable the wall sandbag 100 to be deformed like a pantograph. Thereby, the storage property and portability of the wall sandbag 100 are enhanced. In order to enable rotation as described above, adjacent side walls 110 are connected using a coil 120. A method for connecting the side walls 110 by the coil 120 will be described later.

The wall sandbag 100 does not necessarily have four side walls. Moreover, as long as it can take a rectangular shape by planar view, it may take shapes other than a rectangle.
For example, the wall sandbag 100 shown in FIG. This wall sandbag 100 has six side walls 110.
The left and right edges of the side wall 110 of the wall sandbag 100 are connected so as to be rotatable with respect to the side walls 110 adjacent to each other in the same manner as described above.
Further, although the height of the side wall 110 is the same as in the above case, the lateral width of the side wall 110A is twice the lateral width of the side wall 110B.
As a result, as shown in FIG. 2, the wall sandbag 100 can have a hexagonal shape in plan view (FIG. 2A), or can have a square shape in plan view (see (B )), And can be folded as shown in FIG. Thus, even if it can take other polygonal shapes, if it can take a rectangular (square) shape in a plan view, the conditions for the wall sandbag 100 of the present application are satisfied.

The configuration of the side wall 110 will be described.
Each side wall 110 is rectangular as described above. The width of each side wall 110 may not be the same, but the heights of all the side walls 110 are the same. However, the lateral width of all the side walls of the wall sandbag 100 in this embodiment is the same. Accordingly, the shape of the wall sandbag 100 when viewed in plan is at least a diamond shape and can be a square. In this embodiment, although not necessarily limited to this, the width and height of all the side walls 110 are the same. That is, the side wall 110 of this embodiment is a square. Although not limited to this, the vertical and horizontal lengths of the side wall 110 are often about 1 m to several m.

The side wall 110 is made of a wire mesh. The side wall 110 includes a vertical bar 111 extending in the vertical direction and a horizontal bar 112 extending in the horizontal direction. The multiple vertical bars 111 belonging to the same side wall 110 are all the same length and parallel to each other, and the multiple horizontal bars 112 are the same.
Both the vertical bar 111 and the horizontal bar 112 are metal bars, and are not limited to these, but are round bars made of stainless steel. The vertical bar 111 and the horizontal bar 112 are not limited to this, but are fixed at their intersections so that the horizontal bar 112 is positioned outside the vertical bar 111. The vertical bar 111 and the horizontal bar 112 are fixed by, for example, welding. The relationship between the vertical bar 111 and the horizontal bar 112 is shown in a side view of FIG. 3A and a plan view of FIG.
The intersecting vertical bar 111 and horizontal bar 112 are sandwiched between adjacent vertical bars 111 and form a rectangular eye sandwiched between adjacent horizontal bars 112. The size of the eyes does not necessarily have to be the same, but in this embodiment all are the same.

As described above, each side wall 110 is connected so that the left and right edges can rotate with respect to the adjacent side wall 110 and the left and right edges of the adjacent side walls. The connection may be performed by a known or well-known method. In this embodiment, for example, the coil 120 is used.
The coil 120 is threaded so as to sew the eyes of adjacent side walls 110, thereby fixing adjacent vertical edges of adjacent side walls 100. For example, the coil 120 is sent to the adjacent edges of the two side walls 110 from the upper side while being rotated, and is sent to the lower side so as to sew the eyes of the adjacent side walls 110. It is made the state which fixes the edge to do. The coil 120 does not necessarily have to pass through all the eyes arranged in the longitudinal direction at the extreme end of the side wall 110 fixed thereby.
Instead of the coil, the adjacent side walls 110 can be connected to each other by a known hinge so that the adjacent side walls 110 can rotate with respect to the adjacent side walls 110.

The wall sandbags 100 may include different sizes.
As will be described later, the wall sandbag 100 is filled with contents, but prior to that, the wall sandbag 100 was sized to substantially cover the inside of the interior space of the wall sandbag 100. A bag may be placed and then the contents filled into the bag. Even when such a bag exists, the wall sandbag 100 itself is open at the top and bottom, so that the requirement in the present application that “upper and lower sides are open” is satisfied.
The above two points are also the same for the roof sandbag 300.

Next, the structure of the roof sandbag 300 will be described.
The structure of the roof sandbag 300 is basically the same as that of the wall sandbag 100. The roof sandbag 300 can also be rectangular when viewed in plan, but in this embodiment, it can be rectangular with the same size and shape as the wall sandbag 100 when viewed in plan. .
The height of the roof sandbag 300 is different from that of the wall sandbag 100. The height of the roof sandbag 300 is lower than that of the wall sandbag 100. Although not limited to this, the height of the roof sandbag 300 in this embodiment is about half of the height of the wall sandbag 100.

  Next, the configuration of the roofing material 200 will be described. The roof material 200 is a metal plate. The roofing material 200 is made of, for example, iron. A roof sandbag 300 is placed on the roof material 200 as described later. The roofing material 200 is given strength enough to withstand it.

  A method of constructing a structure using the above structure construction set is as follows.

First, the first-stage wall sandbag 100 is arranged on the ground in an appropriate arrangement (FIG. 4).
Since the wall sandbags 100 are rectangular in plan view, no gaps are unnecessarily formed between the wall sandbags 100 arranged. Needless to say, the arrangement of the wall sandbag 100 is in accordance with the finally obtained structure. The wall sandbag 100 is such that the structure finally obtained can obtain an opening described later. In this embodiment, the wall sandbag 100 is configured to occupy most of the wall sandbag 100 having the above-described configuration, and is arranged in the back of FIG. A wall sandbag 100X is included.
Next, the contents are filled into the wall sandbags 100, 100X (hereinafter collectively referred to as the wall sandbag 100) (FIG. 5).

Next, the second-stage wall sandbag 100 is stacked on the first-stage wall sandbag 100 (FIG. 6). The second-stage wall sandbag 100 does not necessarily match the arrangement of the first-stage wall sandbag 100, but this is the case in this embodiment.
Next, the contents are filled into the internal space of the second-stage wall sandbag 100 (FIG. 7).
In this embodiment, the wall sandbags 100 are stacked in two stages. However, only one stage may be used for placing the roofing material 200, which will be described later, or three stages as necessary. The wall sandbag 100 may be stacked as described above.
The aggregate of the wall sandbags 100 filled with the contents is a wall body in the present application.

  Next, the roof material 200 is placed on the second-stage wall sandbag 100 (FIG. 8). The shape and size of the roofing material 200 is in accordance with the structure finally obtained. Basically, all of the second-stage wall sandbag 100 and the space surrounded by the wall sandbag 100 are used. With a shape and size that exactly covers

Next, the roof sandbag 300 is placed on the roofing material 200 (FIG. 9).
Since the roof sandbag 300 is rectangular in plan view, there is no wasteful gap between the roof sandbags 300 arranged. The roof sandbag 300 is not necessarily limited to this, but basically covers the entire top surface of the roofing material 200. This is the case in this embodiment.
Next, the contents are filled into the inner space of the roof sandbag 300 (FIG. 10).

The structure is completed as described above.
A hole is formed in the front surface of the structure shown in FIG. This is the opening referred to in this application. Further, the space behind the opening is an indoor space as referred to in the present application.
The indoor space of the structure may be used by a person, or vehicles, weapons and other materials may be carried in. The opening is used as the doorway in that case. Note that there may be a plurality of openings.

<Modification 1>
The structure construction set of Modification 1 will be described.

In addition, the structure construction set of the first modification includes a pile. There is at least one pile, but there may be multiple piles.
Next, a method for constructing a structure using the structure construction set will be described.
The modification 1 does not change until the contents in the inner space of the second-stage wall sandbag 100 described in the first embodiment are filled (FIG. 7). In the construction method of the structure according to the first modification, the pile 510 is driven thereafter (FIG. 11A). The pile 510 is driven into the wall sandbag 100 and the ground X in such a manner that the wall sandbag 100 stacked vertically is vertically penetrated and the tip thereof is driven into the ground X (FIG. 11B). The upper end of the pile 510 is flush with the upper surface (or the contents packed in it) of the second-stage wall sandbag 100.
In this embodiment, the pile 510 is driven into all of the wall sandbags 100 except for the small wall sandbag 100X. Pile may be driven, and it is not always necessary that the pile 510 is driven into all of the large wall sandbags 100.
After that, the roof material 200 is placed on the second-stage wall sandbag 100, the roof sandbag 300 is placed thereon, and the interior space of the roof sandbag 300 is filled with the contents. This is the same as in the first embodiment.

In the first modification, the pile 510 is driven after the contents of the second-stage wall sandbag 100 are filled. However, for example, the pile on the ground after the first-stage wall sandbag 100 is arranged. After that, the inner space of the first stage wall sandbag 100 is filled with the contents, and then the second stage wall sandbag 100 is stacked on the first stage wall sandbag 100, and then the second stage. The inner space of the eye wall sandbag 100 may be filled with contents.
If the pile 510 finally penetrates the wall sandbag 100 piled up and down, and the front-end | tip will be driven into the ground X, the front and back of a detailed procedure will not be ask | required.

<Modification 2>
The structure construction set of Modification 2 will be described.
The structure construction set of Modification 2 is basically the same as that of the first embodiment, and includes a wall sandbag 100, a roofing material 200, and a roof sandbag 300. In addition, the structure construction set of Modification 2 includes an internal plate material that is a plate material for making the interior space of the structure a space with a ceiling. In this embodiment, the internal plate material is a rectangular parallelepiped container. The container has an opening corresponding to the opening of the wall body 100 made by the wall sandbag 100.
Next, a method for constructing a structure using the structure construction set will be described.
The modification 2 does not change until the contents in the inner space of the second-stage wall sandbag 100 described in the first embodiment are filled (FIG. 7). In the structure construction method according to the second modification, the container 610 is disposed in an indoor space surrounded by a wall that is an aggregate of the rear wall sandbags 100 (FIG. 12A). The container 610 has a rectangular parallelepiped shape as described above, and has a shape and a size that substantially correspond to a space that becomes an indoor space after being surrounded by a wall. There is an opening on the front surface of the container 610 (there may be an opening on the rear surface), and the opening of the container 610 is made to correspond to a gap between the wall bodies (a portion that later becomes an opening of the structure).
Thereafter, the roof material 200 is placed on the second-stage wall sandbag 100 ((B)), the roof sandbag 300 is placed thereon, and the contents are placed in the inner space of the roof sandbag 300. (C) is the same as in the first embodiment.

In the second modification, the container 610 is arranged before the roof material 200 is placed on the wall body. However, the container 610 is arranged, for example, before the first stage wall sandbag 100 is arranged. Or you may arrange | position after completion of the structure demonstrated in 1st Embodiment.
If a structure as shown in FIG. 12C can be obtained, the arrangement time of the container 610 can be appropriately changed.

<Modification 3>
The structure construction set of Modification 3 will be described.
The structure construction set of Modification 3 is basically the same as that of the first embodiment, and includes a wall sandbag 100, a roof material 200, and a roof sandbag 300. In addition, the structure construction set of Modification 3 includes an internal plate material that is a plate material for making the interior space of the structure a space with a ceiling. In this embodiment, the internal plate is a plate that forms a bowl-shaped space whose front surface (or front and rear surfaces) is open, and more specifically, a known liner plate.
Next, a method for constructing a structure using the structure construction set will be described.
The modification 3 does not change until the contents are filled in the internal space of the second-stage wall sandbag 100 described in the first embodiment (FIG. 7). In the construction method of the structure of the third modification, the internal plate material 620 is disposed in the indoor space surrounded by the wall body that is an aggregate of the rear wall sandbags 100. The inner plate 620 that forms the bowl-shaped space has an opening at least on the front surface thereof. The opening is made to correspond to the gap of the wall body (the part that will later become the opening of the structure). In addition, in the indoor space surrounded by the wall body, the space above the internal plate member 620 is filled with a filler 630 that fills the space (FIG. 13A). The filling 630 may be the same as the contents packed in the wall sandbag 100 and the roof sandbag 300.
Thereafter, the roof material 200 is placed on the second-stage wall sandbag 100 ((B)). The roofing material 200 of this embodiment is provided with connecting rods 520 that penetrate the roofing material 200 up and down on the upper and lower surfaces thereof. However, the connecting rod 520 may be a separate member at the top and bottom of the roofing material 200, and the upper part of the roofing material 200 may not exist depending on circumstances. In addition, for example, a tip of the connection rod 520 may be provided with a protrusion for preventing the connection rod. Further, there may be a plurality of connecting rods 520 in the front-rear direction of FIG.
Next, the roof sandbag 300 is placed on the roof material 200, and the contents are filled in the internal space of the roof sandbag 300 ((C)).
Thus, the structure is completed.

  The internal plate material 620 has a bowl shape as described above. Therefore, the filler 630 placed thereon tends to slide down on both sides (the left and right sides in FIG. 13) of the internal plate material 620. Therefore, the part located in the left and right in FIG. 13 of the wall body is likely to be unstable by receiving a force from the filler 630 toward the outside. However, the portions located on the left and right sides of the wall are connected to at least the roofing material 200 by the connecting rod 520, or are connected to the roofing material 200 and the roof sandbag 300 on the roofing material 200. Hard to become.

<Modification 4>
The structure construction set of Modification 4 will be described.
The structure construction set of Modification 4 is basically the same as that of the first embodiment, and includes a wall sandbag 100, a roofing material 200, and a roof sandbag 300. In addition, the structure construction set of Modification 4 includes an internal plate material which is a plate material for making the interior space of the structure a space with a ceiling, and a connecting aggregate described in detail later. The internal plate material is the same as that of the third modification.
Next, a method for constructing a structure using the structure construction set will be described.
The modification 4 does not change until the contents in the internal space of the second-stage wall sandbag 100 described in the first embodiment are filled (FIG. 7). In the construction method of the structure of the modified example 4, the internal plate material 620 is disposed in the indoor space surrounded by the wall body that is an aggregate of the rear wall sandbags 100. Further, the left and right wall bodies are connected by a connecting aggregate 530 that is, for example, a linear body or a rod-shaped body. There may be a plurality of connecting aggregates 530. Then, when the left and right wall bodies are connected by the connecting aggregate 530, the filling material 630 filling the space is filled in the space above the internal plate member 620 in the indoor space surrounded by the wall bodies (FIG. 14A). )).
Thereafter, the roof material 200 is placed on the second-stage wall sandbag 100 ((B)), the roof sandbag 300 is placed on the roof material 200, and the interior of the roof sandbag 300. The contents are filled into the space ((C)).
Thus, the structure is completed.

  Even in this structure, portions located on the left and right in FIG. 14 of the wall body are likely to become unstable due to receiving force from the filler 630 toward the outside. However, since the portions located on the left and right of the wall are connected to each other by the connecting aggregate 530, they are less likely to become unstable.

<< Second Embodiment >>
The structure construction set according to the second embodiment will be described.
The structure construction set according to the second embodiment is different from that according to the first embodiment in that it does not include the roofing material 200 unlike the first embodiment. The structure construction set according to the second embodiment includes a wall sandbag 100 and a roof sandbag 300. These can be the same as in the first embodiment, and in the second embodiment.
The structure construction set according to the second embodiment includes the same container 610 as that described in the second modification of the first embodiment.

Next, a method for constructing a structure using the structure construction set of the second embodiment will be described.
The second embodiment does not change until the contents in the internal space of the second-stage wall sandbag 100 described in the first embodiment are filled (FIG. 7). In the construction method of the structure of the second embodiment, the container 610 is disposed in the indoor space surrounded by the wall body, which is an aggregate of the rear wall sandbags 100 (FIG. 15A). The container 610 has a shape and a size that substantially correspond to a space that becomes an indoor space after being surrounded by a wall. There is an opening on the front surface of the container 610 (there may be an opening on the rear surface), and the opening of the container 610 is made to correspond to a gap between the wall bodies (a portion that later becomes an opening of the structure).
Thereafter, the roof sandbag 300 is placed on the second-stage wall sandbag 100 and the container 610 (same (B)), and the interior space of the roof sandbag 300 is filled with the contents (same (C )) Is the same as in the first embodiment.

  In addition, what is necessary is just to perform arrangement | positioning of the container 610 in 2nd Embodiment at the appropriate timing before putting the sandbag 300 for roof on the upper surface.

  In addition, the container 610 in the second embodiment has the roof sandbag 300 that cannot be placed as it is on the upper surface of the space surrounded by the wall that later becomes an indoor space because the roof material 200 does not exist. One of its major roles is to place it on the top surface. From that point of view, it is not always necessary to place the box-shaped container 610 in a space that will later become an indoor space, and a plate having a surface corresponding to the upper surface of the container 610 needs to be arranged instead of the container 610. ,It turns out that.

  The structure construction set in the second embodiment may include the pile 510 described in the first modification. The method of using the pile 510 is the same as that described in the first modification.

<Modification 5>

«Third embodiment»
3rd Embodiment demonstrates the sandbag 100 for walls which can be used by 1st, 2nd embodiment and each of those modifications, and its application.

  As described above, the wall sandbag 100 used in the first and second embodiments includes at least four side walls 110. Each side wall 110 is made of a wire mesh. The side wall 110 includes a vertical bar 111 extending in the vertical direction and a horizontal bar 112 extending in the horizontal direction. The multiple vertical bars 111 belonging to the same side wall 110 are all the same length and parallel to each other, and the multiple horizontal bars 112 are the same.

The relationship between the vertical bar 111 and the horizontal bar 112 in the first and second embodiments is as described above, but there is an exception at the edge of the side wall 110.
For example, at the left and right edges of the side wall 110, the vertical bar 111 may be attached to both sides of the horizontal bar 112 to which the side wall 110 is attached. This state is shown in the side view of FIG.
Moreover, in the upper and lower edges of the side wall 110, the horizontal bar 112 may be attached to both sides of the vertical bar 111 to which the side wall 110 is attached. This state is shown in the plan view of FIG.
As described above, at the edge of the side wall 110, the vertical bar 111 at the left and right edges of the side wall 110 or the horizontal bar 112 at the upper and lower edges of the side wall 110 is attached to both sides of the horizontal bar 112 or the vertical bar 111 to which it is attached. May be installed on. Thus, in the edge of the side wall 110, the edge where the horizontal bar 112 is provided on both sides of the vertical bar 111 or the vertical bar 111 is provided on both sides of the horizontal bar 112 is the specific edge referred to in the present application.
In the wall sandbag 100 according to the third embodiment, at least one of the four edges of the side wall 110 is a specific edge in at least one of the four side walls 110 included in the sandbag.

  The specific edge is at least one of the four edges of at least one side wall 111 of the side walls 110. That is, the box-type sandbag 100 of this embodiment has four side walls 110, but at least one of the side walls 110 having a specific edge is present. For example, two of the four side walls 100 or two of the four side walls 110 may have specific edges. Further, the side wall 110 having a specific edge may be such that at least one of the four edges is a specific edge. For example, the side wall 110 having a specific edge may have two edges facing each other, for example, upper and lower edges, or left and right edges, or all four edges may be specific edges.

  In the first and second embodiments, the wall sandbag 100 may be stacked up and down. The wall sandbag 100 of the third embodiment as described above having the side wall 110 having a specific edge may be used for the wall sandbag 100 that is used as a stacked portion.

In the first and second embodiments, for example, the wall sandbag 100 used in the stacked portion has at least one longitudinal edge of at least one side wall 110 included therein as a specific edge. It can be. In this case, the wall sandbag 100 in which both the left and right edges of all the side walls 110 are specific edges can be used as the first-stage wall sandbag 100. As long as both the left and right edges of all the side walls 110 are specified edges, the other edges of the first-stage wall sandbag 100 may be specified edges.
When a structure is formed by stacking a plurality of wall sandbags 100, a large compressive force is applied to the first wall sandbag 100 in the vertical direction. If the first-stage wall sandbag 100 is such that both the left and right edges of all the side walls 110 are specific edges, the first-stage wall sandbag 100 is distorted or damaged. Is less likely to occur.
Note that the same wall sandbag as the first stage can also be used for the wall sandbag 100 above the second stage, but the wall sandbag 100 above the second stage is all from the viewpoint of cost reduction. It is also possible to use the one whose edge is not a specific edge.

In the first and second embodiments, the wall sandbag 100 used in the stacked portion is, for example, one in which at least one lateral edge of at least one side wall 110 included therein is a specific edge. It can be. In the first and second embodiments, the wall sandbags 100 are stacked in two steps. For example, as the first and second wall sandbags 100, both the upper and lower edges of all the side walls 110 are arranged. It is possible to use the sandbag 100 for the wall having a specific edge. In this case, the first and second wall sandbags 100 may have specific edges as long as both upper and lower edges of all the side walls 110 are specific edges. .
FIG. 19 shows an enlarged view of the upper portion of the side wall 110 where the first-stage wall sandbag 100 is located. The upper end of the side wall 110 has a certain surface shape due to the upper surface of the horizontal bar 112 on both sides of the vertical bar 111 and the upper surface of the vertical bar 111. The lower end of the side wall 110 of the second-stage wall sandbag 100 in a state where the top and bottom of FIG. As a result, the second-stage wall sandbag 100 on the first-stage wall sandbag 100 is stabilized.
When the wall sandbags 100 are stacked in three or more stages, the wall sandbag 100 in which both the upper and lower edges of all the side walls 110 are specific edges are added to the wall sandbag 100 above the third stage. Although it is possible to use, the wall sandbag 100 which is not so may be used.
As shown in FIG. 19, there is a gap 113 between the horizontal bars 112 at the upper end of the side wall 110 of the first-stage wall sandbag 100. Similarly, there is a gap 113 between the horizontal bars 112 at the lower end of the side wall 110 of the second-stage wall sandbag 100 stacked thereon. A pin 130 as shown in FIG. 20 can be inserted so as to penetrate both the gaps. The upper end of the pin 130 is bent in a U shape, and the lengths of both ends thereof are different. The long side of the pin 130 is made to pass through the gap 113 between the first and second wall sandbags 100, and the short side of the pin 130 is positioned outside the wall sandbag 100. By doing so, the pin 130 does not come off naturally, but it can be easily pulled out by holding the short side of the pin 130 and pulling it upward.
The pin 130 is disposed between the vertical bar 111 and the vertical bar 111. The pins 130 may be arranged in all the gaps 113 between the adjacent vertical bars 111 or may be arranged in some of such gaps 113. Further, the pin 130 may be used for all the side walls 110 or may not be used.
It is also possible to include the pin 130 together in the structure construction set of the first and second embodiments.

In the first and second embodiments, as described above, the wall sandbag 100 used in the stacked portion has at least one lateral edge of the at least one side wall 110 included therein as a specific edge. Can be. The part constructed | assembled using such a sandbag 100 among structures can be withdrawn with the following method.
For removing the portion of the structure made of the wall sandbag 100 as described above, a removal tool 900 as shown in FIG. 21 is used.
The withdrawal device 900 has a rectangular frame 910, in this embodiment a square. A number of suspending tools 930 are suspended from a lower surface of the frame 910 by a linear body 920 such as a wire. The hanging tool 930 is a hook in this embodiment, but is not limited thereto.
In order to withdraw the structure using the withdrawing device 900, in the case of the first and second embodiments, when withdrawing the wall body, first, the withdrawing device 900 is placed at the lower end of the linear body of the crane. Secure to and lift. Then, the removal tool 900 is positioned on the uppermost wall sandbag 100, and the hanging tool 930 under the removal tool 900 is locked to the uppermost step of each side wall 110 of the wall sandbag 100. To do. Then, the uppermost wall sandbag 100 is lifted together with the removal tool 900 with a crane. As a result, the uppermost wall sandbag 100 is lifted while leaving the contents filled therein.
Next, the same operation is repeated for the second wall sandbag 100 from the top, and this is repeated up to the bottom wall sandbag 100.
By doing so, the wall sandbag 100 can be quickly removed.
If the structure is to be removed by the suspension, the top horizontal bar 112 of each side wall 100 of the wall sandbag 100 to which the load by the suspension is applied is applied to all of the wall sandbags 100 to be suspended. It is preferable to be present on both sides of the vertical bar 111 (that is, the uppermost edge of each side wall 110 of the wall sandbag 100 is a specific edge).
