Description

This invention relates to mounting fixtures, embankment structures, and embankment structure construction methods.

Patent Document 1 discloses a technology related to embankment structures using foamed resin blocks. The foamed resin blocks with sheet members for embankments in Patent Document 1 are characterized in that the sheet members are attached to the mounting surface of the foamed resin block by fastening devices that have fixing portions that are placed on the mounting surface of the foamed resin block to which the sheet member is attached and anchor portions that are embedded in the foamed resin block and restrict movement of the fixing portions in a direction out of the plane of the mounting surface. The fixing portions are positioned on the foamed resin block at at least three locations: two above the mounting surface and one below the mounting surface; the sheet member is fixed to the fixing portions of the fixing devices with fasteners, thereby attaching the sheet member to the mounting surface of the foamed resin block.

Japanese Patent Application Laid-Open No. 2006-169764

In the foam resin blocks with sheet-shaped materials for embankments described in Patent Document 1, the fixing devices include connecting portions that are arranged along the top or bottom surface of the foam resin blocks. Therefore, when foam resin blocks are lined up, the connecting portions arranged along the top or bottom surface of one foam resin block interfere with the adjacent foam resin block. As a result, the position of the foam resin block is shifted from the designed position in the area where the connecting portions interfere, and the positional deviation of the foam resin blocks accumulates and becomes greater as the foam resin blocks are lined up. This interference by the connecting portions poses a problem: the foam resin blocks cannot be placed in the designed position. Another option is to cut the foam resin blocks so that the connecting portions do not interfere, and then place the connecting portions in the cut-out areas, but this requires the work of cutting the foam resin blocks, which increases the time required for construction.

The present invention was devised in light of the above-mentioned problems, and its purpose is to provide a mounting fixture, embankment structure, and embankment structure construction method that allows foam resin blocks for embankments to be placed in the designed position, making construction easier.

The mounting fixture according to the first invention is a mounting fixture for attaching an embankment panel to a foam resin block for embankment use, and comprises a mounting portion for attaching the embankment panel and an insertion plate portion for inserting into the foam resin block. The insertion plate portion is characterized by having a connecting plate portion connected to the mounting portion, an anchor plate portion arranged spaced apart from the mounting portion in a first direction and bent relative to the connecting plate portion in a second direction intersecting the first direction, and claw portions protruding from at least one of the connecting plate portion and the anchor plate portion in a third direction intersecting the first direction and the second direction.

The mounting fixture according to the second invention is the same as the first invention, except that the insertion plate portion is embedded in the foam resin block.

The mounting fixture according to the third invention is the same as the first or second invention, but the mounting portion has a first adjustment portion that adjusts the mounting position of the embankment panel in the third direction.

The mounting fixture according to the fourth invention is any one of the first to third inventions, characterized in that the mounting portion has a second adjustment portion that adjusts the mounting position of the embankment panel in the second direction.

The mounting fixture according to the fifth invention is any one of the first to fourth inventions, characterized in that the mounting portion has a guide plate portion that comes into contact with the outer surface of the foam resin block.

The mounting fixture according to the sixth invention is the same as the fifth invention, but has a through-bolt that passes through the guide plate portion, and the tip of the through-bolt is inserted into the foam resin block.

The seventh aspect of the present invention relates to an embankment structure in which an embankment panel is attached to an embankment foam resin block, and the embankment structure comprises the foam resin block, the embankment panel, and a mounting fixture for attaching the embankment panel to the foam resin block. The mounting fixture comprises a mounting portion for attaching the embankment panel and an insertion plate portion for insertion into the foam resin block. The insertion plate portion has an anchor plate portion arranged spaced apart from the mounting portion in a first direction, a connecting plate portion arranged bent relative to the anchor plate portion in a second direction intersecting the first direction and connecting the mounting portion and the anchor plate portion, and claw portions protruding from at least one of the anchor plate portion and the connecting plate portion in a third direction intersecting the first direction and the second direction.

The embankment structure according to the eighth invention is the seventh invention, characterized in that the insertion plate portion is embedded in the foam resin block.

The embankment structure of the ninth invention is the seventh or eighth invention, characterized in that the mounting fixtures include a first mounting fixture and a second mounting fixture that are arranged spaced apart in the vertical direction on one embankment panel, and the bending resistance of the first mounting fixture is different from the bending resistance of the second mounting fixture.

(First embodiment: embankment structure 100)
FIG. 1 is a cross-sectional view showing an example of an embankment structure 100 in the first embodiment. FIG. 2 is a side view showing an enlarged view of an example of the embankment structure 100 in the first embodiment. FIG. 3 is a plan view showing an enlarged view of an example of the embankment structure 100 in the first embodiment. FIG. 4 is a perspective view showing an example of a mounting fixture 1 in the first embodiment. In the first embodiment, the second direction Y is the up-down direction, and the first direction X and the third direction Z are planar directions that intersect with the up-down direction. The first direction X is the front-to-back direction of the embankment panel 8, and the third direction Z is the left-to-right direction of the embankment panel 8 that intersects with the front-to-back direction.

The embankment structure 100 is an embankment structure in which embankment panels 8 are attached to embankment foam resin blocks 7 via mounting fixtures 1. The embankment structure 100 is a lightweight embankment constructed on a mountain slope 91, with a civil engineering structure 92 such as a road installed on top. The embankment structure 100 comprises foam resin blocks 7, embankment panels 8, and mounting fixtures 1.

The foamed resin blocks 7 can be made from a foamed synthetic resin such as polystyrene, polyurethane, or polyvinyl chloride. The foamed resin blocks 7 are formed in a rectangular parallelepiped shape. Multiple foamed resin blocks 7 are constructed by stacking them in a staggered pattern, with the blocks offset vertically and horizontally. Foamed resin blocks 7 weigh, for example, 12 kg to 30 kg each, making them easy to transport and ideal for lightweight embankment construction work.

The surface of the foam resin block 7 on which the embankment panel 8 is attached is referred to as the front surface 71, the surfaces at the left and right ends of the front surface 71 are referred to as side surfaces 72, the surface at the top end of the front surface 71 in the vertical direction is referred to as the top surface 73, and the surface at the bottom end of the front surface 71 in the vertical direction is referred to as the bottom surface 74.

The embankment panel 8 is attached to the foam resin block 7 via the mounting fixture 1. The embankment panel 8 is attached to the front surface 71 of the foam resin block 7 to protect it. The embankment panel 8 can be any material that can be used as a surface finishing material for civil engineering structures constructed using the lightweight embankment method, such as a concrete panel, resin panel, or metal panel. Multiple mounting fixtures 1 are attached to one embankment panel 8, spaced apart in the vertical direction. The multiple mounting fixtures 1 can be, for example, of the same shape.

The fixture 1 is a metal fitting that attaches the embankment panel 8 to the foam resin block 7. The fixture 1 comprises an attachment portion 2 and an insertion plate portion 3. Multiple fixtures 1 are provided on one embankment panel 8, spaced apart in the vertical and horizontal directions.

The mounting portion 2 mounts the embankment panel 8. The mounting portion 2 has a mounting plate portion 21, a guide plate portion 22, a first adjustment portion 23, a second adjustment portion 24, and a fixing bolt 25. The mounting portion 2 mounts the embankment panel 8 via the fixing bolt 25.

The mounting plate portion 21 is integrally connected to the insertion plate portion 3. The main surface of the mounting plate portion 21 extends along a plane perpendicular to the second direction Y. The mounting plate portion 21 has a long hole 231 formed therein that extends in the third direction Z.

The guide plate portion 22 is bent in the second direction Y relative to the mounting plate portion 21. The guide plate portion 22 has a main surface that extends along a plane perpendicular to the first direction X. A through hole 221 is formed in the guide plate portion 22, and a through bolt 26 is provided in the through hole 221. The through bolt 26 is formed with a pointed tip. The tip of the through bolt 26 is inserted into the foamed resin block 7. This makes it easier to insert the through bolt 26 into the foamed resin block 7. The through bolt 26 may be provided with a washer 261, if necessary. The guide plate portion 22 may be omitted, if necessary.

The first adjustment unit 23 adjusts the mounting position of the embankment panel 8 in the third direction Z. The first adjustment unit 23 has a long hole 231, a first adjustment plate portion 232, and a first fastening fixture 233. The first adjustment plate portion 232 is a plate material bent into an L-shape and has a first plate portion 234 and a second plate portion 235. The first plate portion 234 is formed along the mounting plate portion 21 and is provided with the first fastening fixture 233. The second plate portion 235 is bent in the second direction Y relative to the first plate portion 234 and has a notch portion 241 extending in the second direction Y. The first fastening fixture 233 is, for example, a bolt and nut. The mounting position of the embankment panel 8 in the third direction Z can be adjusted by fastening the first fastening fixture 233 at a predetermined position in the long hole 231. If the mounting position of the embankment panel 8 in the third direction Z can be adjusted, the long hole 231 can be replaced with a notch.

The second adjustment unit 24 adjusts the mounting position of the embankment panel 8 in the second direction Y. The second adjustment unit 24 has a cutout portion 241, a second adjustment plate portion 242, and a second fastening fitting 243. The second adjustment plate portion 242 is a plate material bent into an L-shape and has a third plate portion 244 and a fourth plate portion 245. The third plate portion 244 is formed along the first plate portion 234 and is provided with a second fastening fitting 243. The fourth plate portion 245 is bent relative to the third plate portion 244 in the third direction Z and has a through hole 253 for arranging the fixing bolt 25. A nut 252 is welded and fixed to the fourth plate portion 245. The second fastening fitting 243 can be, for example, a bolt and nut. The mounting position of the embankment panel 8 in the second direction Y can be adjusted by fastening the second fastening fitting 243 at a predetermined position in the cutout portion 241. If the mounting position of the embankment panel 8 in the second direction Y can be adjusted, the cutout portion 241 can be replaced with a long hole.

The fixing bolt 25 is passed through the embankment panel 8. The fixing bolt 25 has a fully threaded shaft that is screwed onto a nut 252. The fixing bolt 25 has a pointed tip. The tip of the fixing bolt 25 is inserted into the foamed resin block 7. This makes it easier to insert the fixing bolt 25 into the foamed resin block 7. The fixing bolt 25 may be provided with a washer 251 as needed. For example, an M8 or M10 bolt is used as the fixing bolt 25.

The insertion plate 3 is inserted into and embedded in the foam resin block 7. The insertion plate 3 and the mounting plate 21 are formed by bending a single plate material approximately 0.5 mm to 4 mm thick. The plate material can be, for example, a steel plate or a stainless steel plate. The insertion plate 3 has a connecting plate portion 31, an anchor plate portion 32, and a claw portion 33.

The connecting plate portion 31 is connected to the mounting plate portion 21 of the mounting portion 2. The main surface of the connecting plate portion 31 is formed along a plane perpendicular to the second direction Y.

The anchor plate portion 32 is positioned away from the mounting plate portion 21 of the mounting portion 2 in the first direction X. The anchor plate portion 32 is positioned so as to be bent relative to the connecting plate portion 31 in the second direction Y, which intersects with the first direction X.

The claw portions 33 protrude from at least one of the connecting plate portion 31 and the anchor plate portion 32 in a third direction Z intersecting the first direction X and the second direction Y. The claw portions 33 have a first claw portion 34 protruding in the third direction from the connecting plate portion 31, and a second claw portion 35 protruding in the third direction from the anchor plate portion 32. Although not shown in the figures, the claw portions 33 may be formed by, for example, the end faces of the plate material protruding in the third direction Z.

The first claw portion 34 has an inclined surface 341 that extends at an angle in the third direction Z, and a flat surface 342 that extends parallel to the third direction Z. The flat surface 342 makes it easier for the first claw portion 34 to be inserted into the foam resin block 7.

The second claw portion 35 has an inclined surface 351 that extends at an angle in the third direction Z, and a flat surface 352 that extends parallel to the third direction Z. The second claw portion 35 has a flat surface 352 that connects to the inclined surface 351, making it easier to insert into the foam resin block 7.

Next, an example of a construction method for the embankment structure 100 will be described. The construction method for the embankment structure 100 is an embankment construction method in which embankment panels are attached to foam resin blocks for the embankment. The construction method for the embankment structure 100 includes, for example, an insertion process and an attachment process.

The construction method for the embankment structure 100 begins with a foamed resin block 7 placed on a slope, as shown in Figure 5(a). In the insertion process, the claws 33 of the insertion plate 3 of the fixture 1 are first inserted into the side surface 72 of the foamed resin block 7, as shown in Figure 5(b). The insertion plate 3 has the claws 33, making it easy to insert into the foamed resin block 7. During the insertion process, the claws 33 are slid along the guide plate 22 toward the front surface 71 of the foamed resin block 7, while the insertion plate 3 is inserted into the foamed resin block 7 so that the mounting portion 2 is exposed on the outside. This prevents the fixture 1 from protruding from the side surface 72 of the foamed resin block 7.

Next, in the installation process, as shown in Figure 6, the embankment panel 8 is attached to the fixture 1 inserted into the foam resin block 7.

In the mounting process, as shown in Figure 6(a), a through-bolt 26 is inserted through the guide plate portion 22, and the tip of the through-bolt 26 is inserted into the foam resin block 7. This firmly fixes the mounting portion 2 to the foam resin block 7.

In the installation process, the first adjustment part 23 is attached to the mounting plate part 21. Specifically, the first fastening fitting 233 provided on the first adjustment plate part 232 is fastened to the elongated hole 231 at a predetermined position.

In the attachment process, the second adjustment part 24 is attached to the first adjustment part 23. Specifically, the second fastening fitting 243 provided on the second adjustment plate part 242 is fastened at a predetermined position in the notch part 241.

In the installation process, as shown in Figure 6(b), the fixing bolt 25 is threaded onto the nut 252, and the embankment panel 8 is fixed via the fixing bolt 25. The tip of the fixing bolt 25 is inserted into the foam resin block 7. This allows the embankment panel 8 to be firmly fixed to the mounting portion 2.

Next, another foam resin block 7 is placed adjacent to the foam resin block 7 in the third direction Z. At this time, the mounting fixture 1 is embedded in the foam resin block 7 and is not exposed from the side surface 72 of the foam resin block 7. In other words, the mounting fixture 1 does not protrude from the side surface 72 when viewed from the front surface 71 of the foam resin block 7. This prevents the mounting fixture 1 from interfering with the other foam resin block 7 when another foam resin block 7 is placed adjacent to one foam resin block 7 in the third direction Z.

This completes one example of a construction method for the embankment structure 100.

In this embodiment, the insertion plate 3 includes a connecting plate 31 connected to the mounting portion 2, an anchor plate 32 spaced apart from the mounting portion 2 in the first direction X and bent relative to the connecting plate 31 in a second direction Y intersecting the first direction X, and claws 33 protruding from at least one of the connecting plate 31 and the anchor plate 32 in a third direction Z intersecting the first direction X and the second direction Y. In other words, the claws 33 protrude from the side end surface of the insertion plate 3 in the third direction Z, which is perpendicular to the plate thickness direction.

As a result, when the insertion plate portion 3 is inserted into the foam resin block 7, the insertion plate portion 3 does not protrude from the side surface 72 of the foam resin block 7. As a result, when another foam resin block 7 is placed adjacent to one foam resin block 7 in the third direction Z, the mounting fixture 1 prevents the other foam resin block 7 from interfering with it. This makes it possible to place foam resin blocks for embankment use in the designed position.

According to this embodiment, the claws 33 protruding in the third direction Z make it easy to insert the foamed resin block 7. This makes it easy to insert not only foamed resin blocks with a relatively low true density (approximately 12 kg/m ³ to 30 kg/m ³ ), but also foamed resin blocks (buoyancy control blocks) with a relatively high true density (approximately 46 kg/m ³ to 70 kg/m ³ ). This makes it possible to safely attach buoyancy control blocks, which were difficult to install with conventional mounting fixtures, to a wall surface.

According to this embodiment, the mounting portion 2 has a first adjustment portion 23 that adjusts the mounting position of the embankment panel 8 in the third direction Z. This allows the embankment panel 8 to be adjusted and mounted to the desired position on-site. This improves the ease of installation of the embankment panel 8.

According to this embodiment, the mounting portion 2 has a second adjustment portion 24 that adjusts the mounting position of the embankment panel 8 in the second direction Y. This allows the embankment panel 8 to be adjusted and mounted to the desired position on-site. This improves the ease of installation of the embankment panel 8.

In this embodiment, the mounting portion 2 has a fixing bolt 25 for fixing the embankment panel 8, and the tip of the fixing bolt 25 is inserted into the foam resin block 7. This allows the embankment panel 8 to be firmly fixed to the foam resin block 7. In particular, the tip of the fixing bolt 25 is formed sharply, making it easier to insert into the foam resin block 7.

In this embodiment, the mounting portion 2 has a guide plate portion 22 that contacts the outer surface of the foamed resin block 7. This allows the foamed resin block 7 to be sandwiched between the anchor plate portion 32 and the guide plate portion 22. This makes it possible to suppress movement of the mounting device 1 in the first direction X.

This embodiment includes a through bolt 26 that penetrates the guide plate portion 22, and the tip of the through bolt 26 is inserted into the foam resin block 7. This allows the mounting fixture 1 to be firmly fixed to the foam resin block 7. In particular, the tip of the through bolt 26 is formed sharply, making it easier to insert into the foam resin block 7.

In this embodiment, the claw portion 33 has an inclined surface that extends in the third direction Z and a flat surface that extends parallel to the third direction Z. This makes it even easier to insert the claw portion 33 into the foam resin block 7. This makes installation even easier.

Conventionally, screws have been used to secure embankment panels 8, but it has been difficult to control the mounting strength of the embankment panels 8 with screws. In addition, screws cannot be attached or removed, and maintenance is not possible. In this regard, this embodiment has a fixing bolt 25 that penetrates the embankment panel 8. This makes it possible to control the mounting strength of the fixing bolt 25 with torque. This makes it possible to improve the safety of the embankment structure.

Furthermore, according to this embodiment, the embankment panel 8 has fixing bolts 25 that penetrate through it. This allows the fixing bolts 25 to be attached and detached, making it easier to maintain the embankment structure.

In this embodiment, the mounting plate portion 21 and the insertion plate portion 3 are made of a single plate material. This allows the plate thickness and material to be set. For example, if the foam resin block 7 is a buoyancy control block that is primarily used below the groundwater level, using a stainless steel plate material can prevent corrosion of the plate material.

(Second embodiment: embankment structure 100)
7 is an enlarged plan view showing an example of the embankment structure 100 according to the second embodiment. In the embankment structure 100 according to the second embodiment, as shown in FIG. 7, the tip of the fixing bolt 25 does not need to be inserted into the foam resin block 7.

(Third embodiment: embankment structure 100)
Figure 8 is an enlarged side view showing an example of an embankment structure 100 in the third embodiment. In the third embodiment, the third direction Z is the up-down direction, and the first direction X and the second direction Y are planar directions intersecting the up-down direction. The first direction X is the front-to-back direction of the embankment panel 8, and the second direction Y is the left-to-right direction with respect to the front of the embankment panel 8, which intersects with the front-to-back direction. In the embankment structure 100 according to the third embodiment, as shown in Figure 8, the insertion plate portion 3 of the mounting fixture 1 is inserted from the upper surface 73 of the foam resin block 7.

According to this embodiment, when the insertion plate portion 3 is inserted into the foam resin block 7, the insertion plate portion 3 does not protrude from the upper surface 73 of the foam resin block 7. Therefore, when another foam resin block 7 is placed adjacent to one foam resin block 7 in the third direction Z, the mounting fixture 1 prevents the other foam resin block 7 from interfering with it. This makes it possible to place the foam resin block for embankment in the designed position.

Furthermore, according to this embodiment, the claw portion 33 protruding in the third direction Z makes it easy to insert the piece into the foam resin block 7. This makes installation easy.

Although not shown, in the embankment structure 100, the insertion plate portion 3 of the mounting fixture 1 may be inserted from the underside 74 of the foam resin block 7.

(Fourth embodiment: embankment structure 100)
9 is an enlarged side view showing an example of an embankment structure 100 according to the fourth embodiment. In the embankment structure 100 according to the fourth embodiment, as shown in FIG. 9, the mounting fixture 1 includes a mounting portion 2, an insertion plate portion 3, and an insertion plate portion 4.

The insertion plate portion 4 is inserted into and embedded in the foam resin block 7. The insertion plate portion 4 has a connecting plate portion 41. The insertion plate portions 3, 4, and the mounting plate portion 21 are formed by bending a single plate material with a thickness of approximately 0.5 mm to 4 mm. The plate material can be, for example, a steel plate or a stainless steel plate.

The connecting plate portion 41 is connected to the mounting plate portion 21 of the mounting portion 2. The main surface of the connecting plate portion 41 is formed along a plane perpendicular to the second direction Y. The connecting plate portion 41 is formed parallel to the connecting plate portion 31.

In this embodiment, the connecting plate portion 41 is formed parallel to the connecting plate portion 31. This improves the bending resistance of the mounting fixture 1 compared to when the connecting plate portion 41 is not included. This makes it possible to increase the weight of the embankment panel 8.

(Fifth embodiment: embankment structure 100)
Fig. 10(a) is an enlarged side view showing a first example of the embankment structure 100 in the fifth embodiment, and Fig. 10(b) is an enlarged plan view showing a second example of the embankment structure 100 in the fifth embodiment. Fig. 11 is a perspective view showing an example of the mounting fixture 1 in the fifth embodiment. In the embankment structure 100 according to the fifth embodiment, as shown in Figs. 10 and 11, the mounting fixture 1 comprises a mounting portion 2, an insertion plate portion 3, and an insertion plate portion 4.

The insertion plate 4 is inserted into and embedded in the foam resin block 7. The insertion plate 4 has a connecting plate 41, an anchor plate 42, and a claw 43. The insertion plate 3, insertion plate 4, and mounting plate 21 are formed by bending a single plate material with a thickness of approximately 0.5 mm to 4 mm. Examples of suitable plate materials include steel and stainless steel.

The connecting plate portion 41 is connected to the mounting plate portion 21 of the mounting portion 2. The main surface of the connecting plate portion 41 is formed along a plane perpendicular to the second direction Y. The connecting plate portion 41 is formed parallel to the connecting plate portion 31.

The anchor plate portion 42 is positioned away from the mounting plate portion 21 of the mounting portion 2 in the first direction X. The anchor plate portion 42 is positioned so as to be bent relative to the connecting plate portion 41 in the second direction Y, which intersects with the first direction X. The anchor plate portion 42 is formed parallel to the anchor plate portion 32.

The claw portions 43 protrude from at least one of the connecting plate portion 41 and the anchor plate portion 42 in the third direction Z, which intersects with the first direction X and the second direction Y. The claw portions 43 protrude in the same direction as the claw portions 33. The claw portions 43 have a third claw portion 44 that protrudes from the connecting plate portion 31 in the third direction Z, and a fourth claw portion 45 that protrudes from the anchor plate portion 42 in the third direction Z. Although not shown in the figures, the claw portions 43 may be formed by, for example, the end faces of the plate material protruding in the third direction Z.

The third claw portion 44 has an inclined surface that extends in the third direction Z.

The fourth claw portion 45 has an inclined surface that extends in the third direction Z and a flat surface that extends parallel to the third direction Z. By having a flat surface that connects to the inclined surface, the fourth claw portion 45 can be easily inserted into the foam resin block 7.

In particular, according to this embodiment, the connecting plate portion 41 is formed parallel to the connecting plate portion 31. This improves the bending resistance of the mounting fixture 1 compared to a case in which the connecting plate portion 41 is not included. This makes it possible to increase the weight of the embankment panel 8.

In particular, according to this embodiment, the anchor plate portion 42 is formed parallel to the anchor plate portion 32. This improves the pull-out resistance of the mounting fixture 1 in the first direction X.

In particular, according to this embodiment, the insertion plate 4 includes a connecting plate 41 connected to the mounting portion 2, an anchor plate 42 spaced apart from the mounting portion 2 in the first direction X and bent relative to the connecting plate 41 in a second direction Y intersecting the first direction X, and a claw 43 protruding from at least one of the connecting plate 41 and the anchor plate 42 in a third direction Z intersecting the first direction X and the second direction Y. In other words, the claw 43 protrudes from the side end surface of the insertion plate 3 in the third direction Z, which is perpendicular to the plate thickness direction.

As a result, when the insertion plate portion 4 is inserted into the foam resin block 7, the insertion plate portion 4 does not protrude from the side surface 72 of the foam resin block 7. Therefore, when another foam resin block 7 is placed adjacent to one foam resin block 7 in the third direction Z, the mounting fixture 1 prevents the other foam resin block 7 from interfering with it. This makes it possible to place the foam resin block 7 for embankment use in the designed position.

In particular, according to this embodiment, the claws 43 protruding in the third direction Z make it easy to insert the foamed resin block 7. This makes it easy to insert not only foamed resin blocks with a relatively low true density (approximately 12 kg/m ³ to 30 kg/m ³ ), but also foamed resin blocks (buoyancy control blocks) with a relatively high true density (approximately 46 kg/m ³ to 70 kg/m ³ ). This makes it possible to safely attach buoyancy control blocks, which were difficult to install with conventional mounting fixtures, to a wall surface.

(Sixth embodiment: embankment structure 100)
FIG. 12 is a schematic diagram showing an example of an embankment panel 8 when an upper load acts on a foamed resin block 7. In FIG. 12 , the foamed resin block 7 and the embankment panel 8 before deformation are indicated by solid lines, and the foamed resin block 7 and the embankment panel 8 after deformation due to an external force P are indicated by dashed lines. As shown in FIG. 12 , multiple mounting fixtures 1 are attached to one embankment panel 8 at vertically spaced intervals. When the foamed resin blocks 7 are stacked and an external force P, such as an upper load, acts on the foamed resin blocks 7, the foamed resin blocks 7 contract in the vertical direction. As the foamed resin blocks 7 contract, stress due to deformation of the foamed resin blocks 7 is transmitted to the embankment panel 8, causing the embankment panel 8 attached to the mounting fixture 1 to deform in the first direction X, potentially resulting in damage. In the embankment structures 100 in the following sixth and seventh embodiments, deformation of the embankment panel 8 is suppressed.

Figure 13 is an enlarged side view showing an example of an embankment structure 100 in the sixth embodiment.

A plurality of mounting fixtures 1 are provided on a single embankment panel 8, spaced apart in the vertical direction. In the embankment structure 100, for example, of the multiple mounting fixtures 1 attached to a single embankment panel 8, the mounting fixture 1 attached to the upper side is referred to as the upper mounting fixture 1, and the mounting fixture 1 attached below the upper mounting fixture 1 is referred to as the lower mounting fixture 1.

In the embankment structure 100, of the multiple mounting fixtures 1 attached to one embankment panel 8, it is preferable that the bending resistance of the upper mounting fixture 1 differ from the bending resistance of the lower mounting fixture 1. This makes it easier for the mounting fixture 1 with low bending resistance to bend and deform when the foamed resin blocks 7 are stacked and an external force in the vertical direction, such as a surcharge load, acts on them. By deforming the mounting fixture 1 with low bending resistance, the stress transmitted to the embankment panel 8 can be reduced. Therefore, when the foamed resin block 7 is deformed by an external force (surcharge load), deformation of the embankment panel 8 in the first direction X is suppressed, allowing the embankment panel 8 to be stably attached over the long term. Bending resistance can be evaluated, for example, using the section modulus and second moment of area of the mounting fixture 1.

The bending resistance of the upper mounting fixture 1 and the bending resistance of the lower mounting fixture 1 may be made different, for example, by making the pressure-receiving area of the insertion plate portion 3 used in the upper mounting fixture 1 different from the pressure-receiving area of the insertion plate portion 3 used in the lower mounting fixture 1. Making the pressure-receiving areas different may be made, for example, by providing holes 39 of different sizes in the insertion plate portion 3 of the upper mounting fixture 1 and the insertion plate portion 3 of the lower mounting fixture 1. Alternatively, making the pressure-receiving areas different may be made, for example, by providing holes 39 in either the insertion plate portion 3 of the upper mounting fixture 1 or the insertion plate portion 3 of the upper mounting fixture 1.

When the bending resistance of the upper mounting fixture 1 is made different from the bending resistance of the lower mounting fixture 1, this may be achieved, for example, by making the thickness of the plate material used in the upper mounting fixture 1 different from the thickness of the plate material used in the lower mounting fixture 1. When the bending resistance of the upper mounting fixture 1 is made different from the material of the plate material used in the upper mounting fixture 1, this may be achieved, for example, by making the material of the plate material used in the lower mounting fixture 1 different.

According to this embodiment, the mounting fixture 1 has a first mounting fixture 1 and a second mounting fixture 1 arranged at a distance in the vertical direction on one embankment panel 8, and the bending resistance of the first mounting fixture 1 is different from the bending resistance of the second mounting fixture 1. This makes it easier for the mounting fixture 1, which has low bending resistance, to bend and deform when foamed resin blocks 7 are stacked and an external force in the vertical direction, such as an upper load, acts on them. Therefore, when the foamed resin blocks 7 are deformed by an external force in the vertical direction (upper load), deformation of the embankment panel 8 in the first direction X is suppressed, allowing the embankment panel 8 to be attached stably over the long term.

(Seventh embodiment: embankment structure 100)
Fig. 14 is an enlarged side view showing a first example of the embankment structure 100 according to the seventh embodiment. Fig. 15 is an enlarged side view showing a second example of the embankment structure 100 according to the seventh embodiment.

A plurality of mounting fixtures 1 are provided on a single embankment panel 8, spaced apart in the vertical direction. In the embankment structure 100, for example, of the multiple mounting fixtures 1 attached to a single embankment panel 8, the mounting fixture 1 attached to the upper side is referred to as the upper mounting fixture 1, and the mounting fixture 1 attached below the upper mounting fixture 1 is referred to as the lower mounting fixture 1.

In the embankment structure 100, of the multiple mounting fixtures 1 attached to one embankment panel 8, it is preferable that at least one of the mounting portions 2 of the upper mounting fixture 1 and the lower mounting fixture 1 be able to move vertically to attach the embankment panel 8. This allows the mounting portions 2 to which the embankment panel 8 is attached to move vertically when the foamed resin blocks 7 are stacked and an external force in the vertical direction, such as a surcharge load, is applied. By moving the mounting portions 2 vertically, the stress transmitted to the embankment panel 8 can be reduced. Therefore, when the foamed resin blocks 7 are deformed by an external force (surcharge load), deformation of the embankment panel 8 in the first direction X is suppressed, allowing the embankment panel 8 to be attached stably over the long term.

In the embodiment shown in Figure 14, the second direction Y is the vertical direction, and the first direction X and third direction Z are planar directions intersecting the vertical direction. In this case, for example, the upper and lower mounting fixtures 1 are inserted from the side surface 72 of the foam resin block 7. Then, either the second fastening fitting 243 of the upper mounting fixture 1 or the second fastening fitting 243 of the lower mounting fixture 1 is fastened and attached, while the other is attached without fastening or with reduced fastening force. This allows the second fastening fitting 243 to move in the direction of arrow S in the figure within the notch portion 241 extending vertically. In this way, the second adjustment portion 24 allows the mounting portion 2 to attach the embankment panel 8 in a manner that allows it to move vertically.

In the embodiment shown in Figure 15, the third direction Z is the vertical direction, and the first direction X and second direction Y are planar directions intersecting the vertical direction. In this case, the upper mounting fixture 1 is inserted from the upper surface 73 of the foamed resin block 7, and the lower mounting fixture 1 is inserted from the lower surface 74 of the foamed resin block 7. Then, either the first fastening fitting 233 of the upper mounting fixture 1 or the first fastening fitting 233 of the lower mounting fixture 1 is fastened and attached, while the other is attached without fastening or with reduced fastening force. This allows the first fastening fitting 233 to move in the direction of arrow S in the figure within the elongated hole 231 extending vertically. In this way, the first adjustment unit 23 allows the mounting unit 2 to attach the embankment panel 8 in a manner that allows it to move vertically.

According to this embodiment, the mounting fixture 1 has a first mounting fixture 1 and a second mounting fixture 1 arranged at a distance in the vertical direction on one embankment panel 8, and the mounting portion 2 of at least one of the first mounting fixture 1 and the second mounting fixture 1 is capable of moving in the vertical direction when the embankment panel 8 is attached to the mounting fixture 1. This allows the mounting portion 2 attached to the embankment panel 8 to move in the vertical direction when foamed resin blocks 7 are stacked and an external force in the vertical direction, such as an upper load, is applied. Therefore, when the foamed resin blocks 7 are deformed by an external force in the vertical direction (upper load), deformation of the embankment panel 8 in the first direction X is suppressed, allowing the embankment panel 8 to be attached stably over the long term.

These novel embodiments may be embodied in a variety of other forms, and various omissions, substitutions, and modifications may be made without departing from the spirit of the invention.
