[Technical Field]

[0001] The present invention relates to a mounting fixture, an embankment structure, and a method for constructing an embankment structure. [Background technology]

[0002] Patent Document 1 discloses a conventional technique relating to an embankment structure using a foamed resin block. The foamed resin block with a sheet material for embankment in Patent Document 1 is characterized in that the sheet material is attached to the mounting surface of the foamed resin block by providing a fastener having a fixing portion that is placed on the mounting surface of the foamed resin block of the sheet material and an anchor portion that is embedded in the foamed resin block and restricts movement of the fixing portion in an out-of-plane direction of the mounting surface, with the fixing portions positioned at at least three locations on the mounting surface (two above and one below), and by fixing the sheet material to the mounting surface of the foamed resin block by fasteners.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-169764 Summary of the Invention [Problem to be solved by the invention]

[0004] In the foam resin blocks with panel-shaped members for embankments described in Patent Document 1, the fasteners include connecting portions arranged along the upper or lower surface of the foam resin blocks. Therefore, when foam resin blocks are arranged side by side, the connecting portions arranged along the upper or lower 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 its designed position by the portion where the connecting portions interfere, and the positional deviation of the foam resin blocks accumulates and becomes larger as the foam resin blocks are arranged. This interference between the connecting portions poses a problem: the foam resin blocks cannot be placed in their designed positions. Another option is to remove the foam resin blocks so that the connecting portions do not interfere and then place the connecting portions in the removed portions, but this requires the work of removing the foam resin blocks, which increases the construction time.

[0005] The present invention was devised in consideration of the above-mentioned problems, and its purpose is to provide a mounting fixture, an embankment structure, and a construction method for an embankment structure that allows foam resin blocks for embankments to be placed in the designed position, making construction easier.

[0019] Hereinafter, an example of a mounting tool, an embankment structure, and a construction method for an embankment structure according to an embodiment of the present invention will be described with reference to the drawings.

[0020] (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 an embankment structure 100 in the first embodiment. FIG. 3 is a plan view showing an enlarged view of an example of an 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.

[0021] 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 provided on the upper side. The embankment structure 100 comprises the foam resin blocks 7, the embankment panels 8, and the mounting fixtures 1.

[0022] The foamed resin blocks 7 can be made of a foamed material made of synthetic resin such as polystyrene, polyurethane, or polyvinyl chloride. The foamed resin blocks 7 are formed in a rectangular parallelepiped shape. The foamed resin blocks 7 are constructed by stacking multiple blocks in a staggered pattern, with the blocks offset in the vertical and horizontal directions. The foamed resin blocks 7 weigh, for example, 12 kg to 30 kg each, making them easy to carry and ideal for use in lightweight embankment construction work.

[0023] The surface of the foamed resin block 7 on which the embankment panel 8 is attached is referred to as the front surface 71, the surfaces on the left and right side edges of the front surface 71 are referred to as side surfaces 72, the surface on the top edge of the front surface 71 in the vertical direction is referred to as the top surface 73, and the surface on the bottom edge of the front surface 71 in the vertical direction is referred to as the bottom surface 74.

[0024] 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 71 side of the foam resin block 7 to protect the foam resin block 7. The embankment panel 8 can be any panel that can be used as a surface finishing material for civil engineering structures constructed using the lightweight embankment method, and concrete panels, resin panels, metal panels, etc. can be used. A plurality of mounting fixtures 1 are attached to one embankment panel 8, spaced apart in the vertical direction. The multiple mounting fixtures 1 are, for example, of the same shape.

[0025] The mounting fixture 1 is a metal fitting that attaches an embankment panel 8 to a foam resin block 7. The mounting fixture 1 comprises an attachment portion 2 and an insertion plate portion 3. A plurality of mounting fixtures 1 are provided on one embankment panel 8, spaced apart in the vertical and horizontal directions.

[0026] 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.

[0027] 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 an elongated hole 231 formed therein that extends in the third direction Z.

[0028] 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 extending 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 as needed. The guide plate portion 22 may be omitted as needed.

[0029] The first adjustment unit 23 adjusts the attachment position of the embankment panel 8 in the third direction Z. The first adjustment unit 23 has a slot 231, a first adjustment plate 232, and a first fastening tool 233. The first adjustment plate 232 is a plate material bent into an L shape and has a first plate 234 and a second plate 235. The first plate 234 is formed along the attachment plate 21, and is provided with the first fastening tool 233. The second plate 235 is bent in the second direction Y relative to the first plate 234, and is formed with a notch 241 extending in the second direction Y. The first fastening tool 233 is, for example, a bolt and nut. The attachment position of the embankment panel 8 in the third direction Z can be adjusted by fastening the first fastening tool 233 at a predetermined position in the slot 231. If the mounting position of the banking panel 8 in the third direction Z can be adjusted, the long hole 231 can be replaced with a notch.

[0030] 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 notch 241, a second adjustment plate 242, and a second fastening fixture 243. The second adjustment plate 242 is a plate bent into an L shape and has a third plate 244 and a fourth plate 245. The third plate 244 is formed along the first plate 234 and is provided with the second fastening fixture 243. The fourth plate 245 is bent relative to the third plate 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 245. The second fastening fixture 243 is, for example, a bolt and a nut. The mounting position of the embankment panel 8 in the second direction Y can be adjusted by fastening the second fastening fixture 243 at a predetermined position in the notch 241. If the mounting position of the banking panel 8 in the second direction Y can be adjusted, the notch 241 can be replaced with a long hole.

[0031] 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 necessary. As the fixing bolt 25, for example, an M8 or M10 bolt is used.

[0032] The insertion plate 3 is inserted into and embedded in the foam resin block 7. The insertion plate 3 and the attachment plate 21 are formed by bending a single plate material with a thickness of approximately 0.5 mm to 4 mm. The plate material may 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.

[0033] 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.

[0034] The anchor plate portion 32 is arranged to be spaced apart from the mounting plate portion 21 of the mounting portion 2 in the first direction X. The anchor plate portion 32 is arranged to be bent relative to the connecting plate portion 31 in a second direction Y that intersects with the first direction X.

[0035] 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 first claw portions 34 protruding in the third direction from the connecting plate portion 31 and second claw portions 35 protruding in the third direction from the anchor plate portion 32. Although not shown in the drawings, the claw portions 33 may be formed by, for example, an end face of a plate material protruding in the third direction Z.

[0036] 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 first claw portion 34 has the flat surface 342, which makes it easier to insert the first claw portion 34 into the foamed resin block 7.

[0037] The second claw portion 35 has an inclined surface 351 that extends obliquely in the third direction Z, and a flat surface 352 that extends parallel to the third direction Z. The second claw portion 35 has the flat surface 352 that is connected to the inclined surface 351, which makes it easier to insert the second claw portion 35 into the foamed resin block 7.

[0038] Next, we will explain an example of a construction method for the embankment structure 100. The construction method for the embankment structure 100 is an embankment construction method in which embankment panels are attached to foam resin blocks for embankment. The construction method for the embankment structure 100 includes, for example, an insertion process and an attachment process.

[0039] The construction method for the embankment structure 100 begins with a state in which a foamed resin block 7 has been placed on a slope, as shown in FIG. 5(a). In the insertion process, first, as shown in FIG. 5(b), the claws 33 of the insertion plate 3 of the mounting fixture 1 are inserted from the side surface 72 of the foamed resin block 7. The insertion plate 3 has the claws 33, which allows it to be easily inserted into the foamed resin block 7. In the insertion process, the claws 33 are slid along the guide plate 22 to 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 to the outside of the foamed resin block 7. This prevents the mounting fixture 1 from protruding from the side surface 72 of the foamed resin block 7.

[0040] Next, in the mounting step, as shown in FIG. 6, the banking panel 8 is mounted to the mounting fixture 1 inserted into the foam resin block 7.

[0041] 6(a), in the mounting step, a through-bolt 26 is inserted through the guide plate portion 22, and the tip of the through-bolt 26 is inserted into the foamed resin block 7. This allows the mounting portion 2 to be firmly fixed at the mounting position on the foamed resin block 7.

[0042] In the attachment step, the first adjustment part 23 is attached to the attachment plate part 21. More specifically, the first fastening metal fitting 233 provided on the first adjustment plate part 232 is fastened to the elongated hole 231 at a predetermined position.

[0043] In the attachment step, the second adjustment part 24 is attached to the first adjustment part 23. In detail, the second fastening metal fitting 243 provided on the second adjustment plate part 242 is fastened to the notch part 241 at a predetermined position.

[0044] In the mounting process, as shown in FIG. 6(b), the fixing bolt 25 is screwed into 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.

[0045] Next, another foamed resin block 7 is placed adjacent to the foamed resin block 7 in the third direction Z. At this time, the mounting fixture 1 is embedded in the foamed resin block 7 and is not exposed from the side surface 72 of the foamed 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 side of the foamed resin block 7. This makes it possible to prevent the mounting fixture 1 from interfering with the other foamed resin block 7 when the other foamed resin block 7 is placed adjacent to one foamed resin block 7 in the third direction Z.

[0046] This completes one example of the construction method for the embankment structure 100.

[0047] According to this embodiment, the insertion plate 3 has 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 toward a second direction Y intersecting the first direction X with respect to the connecting plate 31, 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. That is, the claws 33 protrude from a side end face of the insertion plate 3 in the third direction Z, which is perpendicular to the plate thickness direction.

[0048] As a result, when the insertion plate portion 3 is inserted into the foamed resin block 7, the insertion plate portion 3 does not protrude from the side surface 72 of the foamed resin block 7. As a result, when another foamed resin block 7 is placed adjacent to one foamed resin block 7 in the third direction Z, the mounting fixture 1 can prevent the other foamed resin block 7 from interfering with it. This makes it possible to place the foamed resin blocks for embankment in the designed position.

[0049] According to this embodiment, since the claw portions 33 protruding in the third direction Z are provided, the work of inserting the block into the foamed resin block 7 can be easily performed. 3 ~30kg / m 3 Not only foamed resin blocks with a relatively high true density (46 kg / m 3 ~70kg / m 3 Even foam resin blocks (buoyancy control blocks) of about 1 / 4" thick can be easily inserted. This means that even buoyancy control blocks, which were difficult to install with conventional mounting fixtures, can now be safely attached to wall surfaces.

[0050] 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 a desired position on site. This makes it possible to improve the workability of the embankment panel 8.

[0051] 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 a desired position on site. This makes it possible to improve the workability of the embankment panel 8.

[0052] According to 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 foamed resin block 7. This makes it possible to firmly fix the embankment panel 8 to the foamed resin block 7. In particular, since the tip of the fixing bolt 25 is formed sharp, it is possible to make it easier to insert it into the foamed resin block 7.

[0053] According to this embodiment, the mounting portion 2 has a guide plate portion 22 that comes into contact with the outer surface of the foamed resin block 7. This causes 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.

[0054] According to this embodiment, there is provided a through bolt 26 that passes through the guide plate portion 22, and the tip of the through bolt 26 is inserted into the foamed resin block 7. This makes it possible to firmly fix the mounting device 1 to the foamed resin block 7. In particular, since the tip of the through bolt 26 is formed sharp, it is possible to make insertion into the foamed resin block 7 easier.

[0055] According to this embodiment, the claw portion 33 has an inclined surface that extends obliquely in the third direction Z and a flat surface that extends parallel to the third direction Z. This makes it easier to insert the claw portion 33 into the foamed resin block 7. This makes installation even easier.

[0056] Conventionally, screws have been used to fasten 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 detached, and maintenance is not possible. In this regard, this embodiment has fixing bolts 25 that penetrate the embankment panels 8. This makes it possible to control the mounting strength of the fixing bolts 25 with torque. This makes it possible to improve the safety of the embankment structure.

[0057] 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 possible to easily perform maintenance on the embankment structure.

[0058] According to this embodiment, a single plate is used for the mounting plate 21 and the insertion plate 3. This allows the thickness and material of the plate to be set. For example, if the foamed resin block 7 is a buoyancy control block that is mainly used below the groundwater level, using a stainless steel plate can prevent corrosion of the plate.

[0059] (Second embodiment: embankment structure 100) Fig. 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, the tip of the fixing bolt 25 does not have to be inserted into the foamed resin block 7, as shown in Fig. 7.

[0060] (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 vertical direction, and the first direction X and the second direction Y are planar directions that intersect with the vertical direction. The first direction X is the front-to-rear 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-rear direction. In the embankment structure 100 in 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.

[0061] According to this embodiment, when the insertion plate portion 3 is inserted into the foamed resin block 7, the insertion plate portion 3 does not protrude from the upper surface 73 of the foamed resin block 7. Therefore, when another foamed resin block 7 is placed adjacent to one foamed resin block 7 in the third direction Z, the mounting fixture 1 can prevent interference with the other foamed resin block 7. This makes it possible to place the foamed resin block for embankment in the designed position.

[0062] Furthermore, according to this embodiment, since the claw portions 33 protruding in the third direction Z are provided, the insertion work into the foamed resin block 7 can be easily performed. Therefore, the installation can be easily performed.

[0063] Although not shown, in the embankment structure 100, the insertion plate portion 3 of the mounting fixture 1 may be inserted from the lower surface 74 of the foamed resin block 7.

[0064] (Fourth embodiment: embankment structure 100) 9 is an enlarged side view showing an example of the 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.

[0065] 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 portion 3, the insertion plate portion 4, and the attachment plate portion 21 are formed by bending a single plate material with a thickness of about 0.5 mm to 4 mm. The plate material can be, for example, a steel plate, a stainless steel plate, or the like.

[0066] 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.

[0067] 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 where the connecting plate portion 41 is not provided. This makes it possible to increase the weight of the embankment panel 8.

[0068] (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 a mounting fixture 1 in the fifth embodiment. In the embankment structure 100 in 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.

[0069] 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, an anchor plate portion 42, and a claw portion 43. The insertion plate portion 3, the insertion plate portion 4, and the mounting plate portion 21 are formed by bending a single plate material with a thickness of about 0.5 mm to 4 mm. The plate material can be, for example, a steel plate, a stainless steel plate, or the like.

[0070] 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.

[0071] The anchor plate 42 is disposed at a distance from the mounting plate 21 of the mounting portion 2 in the first direction X. The anchor plate 42 is disposed so as to be bent relative to the connecting plate 41 in a second direction Y that intersects with the first direction X. The anchor plate 42 is formed parallel to the anchor plate 32.

[0072] The claw portions 43 protrude from at least one of the connecting plate portion 41 and the anchor plate portion 42 in a third direction Z intersecting 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 protruding from the connecting plate portion 31 in the third direction Z, and a fourth claw portion 45 protruding from the anchor plate portion 42 in the third direction Z. Although not shown in the drawings, the claw portions 43 may be formed by, for example, an end face of a plate material protruding in the third direction Z.

[0073] The third claw portion 44 has an inclined surface that extends in the third direction Z at an angle.

[0074] The fourth claw portion 45 has an inclined surface that extends obliquely in the third direction Z and a flat surface that extends parallel to the third direction Z. The fourth claw portion 45 can be easily inserted into the foamed resin block 7 by having the flat surface that is connected to the inclined surface.

[0075] 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 where the connecting plate portion 41 is not provided. This makes it possible to increase the weight of the embankment panel 8.

[0076] In particular, according to this embodiment, anchor plate portion 42 is formed parallel to anchor plate portion 32. This makes it possible to improve the pull-out resistance of mounting fixture 1 in first direction X.

[0077] In particular, according to this embodiment, the insertion plate 4 has a connecting plate 41 connected to the mounting portion 2, an anchor plate 42 arranged spaced apart from the mounting portion 2 in the first direction X and bent toward a second direction Y intersecting the first direction X with respect to the connecting plate 41, and claws 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. That is, the claws 43 protrude from the side end surface of the insertion plate 3 in the third direction Z perpendicular to the plate thickness direction.

[0078] As a result, when the insertion plate portion 4 is inserted into the foamed resin block 7, the insertion plate portion 4 does not protrude from the side surface 72 of the foamed resin block 7. Therefore, when another foamed resin block 7 is placed adjacent to one foamed resin block 7 in the third direction Z, the mounting fixture 1 can prevent interference with the other foamed resin block 7. This makes it possible to place the foamed resin block 7 for embankment in the designed position.

[0079] In particular, according to this embodiment, since the claw portions 43 protruding in the third direction Z are provided, the insertion work into the foamed resin block 7 can be easily performed. 3 ~30kg / m 3Not only foamed resin blocks with a relatively high true density (46 kg / m 3 ~70kg / m 3 Even foam resin blocks (buoyancy control blocks) of about 1 / 4" thick can be easily inserted. This means that even buoyancy control blocks, which were difficult to install with conventional mounting fixtures, can now be safely attached to wall surfaces.

[0080] (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 vertical intervals. When the foamed resin blocks 7 are stacked and an external force P, such as an upper load, acts on them, 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, and the embankment panel 8 attached to the mounting fixture 1 deforms in the first direction X, which may result in damage. In the embankment structures 100 in the following sixth and seventh embodiments, deformation of the embankment panel 8 is suppressed.

[0081] FIG. 13 is an enlarged side view showing an example of the embankment structure 100 according to the sixth embodiment.

[0082] A plurality of mounting fixtures 1 are provided spaced apart in the vertical direction on one embankment panel 8. In the embankment structure 100, for example, of the plurality of mounting fixtures 1 attached to one 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.

[0083] In the embankment structure 100, among the multiple mounting fixtures 1 attached to one embankment panel 8, it is preferable that the bending resistance of the upper mounting fixture 1 differs 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, it is possible to reduce the stress transmitted to the embankment panel 8. Therefore, when the foamed resin block 7 is deformed by an external force (surcharge load), etc., 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, by the section modulus and second moment of area of ​​the mounting fixture 1.

[0084] 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. The pressure-receiving areas may be made different, 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. In addition, the pressure-receiving areas may be made different, 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.

[0085] A case in which the bending resistance of the upper mounting fixture 1 and the bending resistance of the lower mounting fixture 1 are made different may be realized, for example, by making the plate thickness of the plate material used in the upper mounting fixture 1 different from the plate thickness of the plate material used in the lower mounting fixture 1. A case in which the bending resistance of the upper mounting fixture 1 and the bending resistance of the lower mounting fixture 1 are made different from the plate material used in the upper mounting fixture 1.

[0086] According to this embodiment, the mounting fixture 1 has a first mounting fixture 1 and a second mounting fixture 1 that are arranged spaced apart 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 a surcharge load, acts on them. Therefore, when the foamed resin blocks 7 are deformed by an external force in the vertical direction (surcharge load), deformation of the embankment panel 8 in the first direction X is suppressed, and the embankment panel 8 can be stably attached over the long term.

[0087] (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.

[0088] A plurality of mounting fixtures 1 are provided spaced apart in the vertical direction on one embankment panel 8. In the embankment structure 100, for example, of the plurality of mounting fixtures 1 attached to one 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.

[0089] 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 is attached so that the embankment panel 8 can be moved in the vertical direction. This allows the mounting portions 2 to which the embankment panel 8 is attached to be moved in the vertical direction when the foamed resin blocks 7 are stacked and an external force in the vertical direction, such as a surcharge load, acts on them. Moving the mounting portions 2 in the vertical direction reduces the stress transmitted to the embankment panel 8. Therefore, when the foamed resin blocks 7 are deformed by an external force (surcharge load), etc., deformation of the embankment panel 8 in the first direction X is suppressed, and the embankment panel 8 can be attached stably over the long term.

[0090] In the embodiment shown in FIG. 14 , the second direction Y is the vertical direction, and the first direction X and the 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, and the other is attached without fastening or with a 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 in the vertical direction. In this way, the second adjustment unit 24 attaches the embankment panel 8 to the mounting unit 2 so that it can be moved in the vertical direction.

[0091] In the embodiment shown in FIG. 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 top surface 73 of the foamed resin block 7, and the lower mounting fixture 1 is inserted from the bottom 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, and the other is attached without fastening or with a 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 in the vertical direction. In this way, the first adjustment unit 23 attaches the embankment panel 8 to the mounting unit 2 so that it can be moved in the vertical direction.

[0092] According to this embodiment, the mounting fixture 1 has a first mounting fixture 1 and a second mounting fixture 1 that are arranged spaced apart in the vertical direction on one embankment panel 8, and at least one of the mounting portion 2 of the first mounting fixture 1 and the mounting portion 2 of the second mounting fixture 1 is capable of vertically moving to mount the embankment panel 8. 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, acts on the foamed resin blocks 7. 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, and the embankment panel 8 can be stably mounted over the long term.
