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 between the connecting portions poses a problem: the foam resin blocks cannot be placed in the designed position. Therefore, if the foam resin blocks are cut to prevent the connecting portions from interfering and the connecting portions are placed in the cut-out areas, the foam resin blocks must be cut again, which increases the construction time.

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 present invention is a mounting fixture for mounting an embankment panel to a foam resin block for embankment, and comprises a U-shaped mounting plate portion formed with through holes for providing fasteners to be attached to the embankment panel, a first connecting plate portion and a second connecting plate portion formed on both ends of the mounting plate portion, a first anchor plate portion formed by bending an end of the first connecting plate portion opposite to the end of the first connecting plate portion toward the outer surface of the first connecting plate portion, and an end of the second connecting plate portion opposite to the end of the second connecting plate portion. a second anchor plate portion formed by bending the first anchor plate portion toward the outer surface of the second connecting plate portion ; a first claw portion protruding so that the end face of the bending portion between the first connecting plate portion and the first anchor plate portion becomes its apex; a second claw portion protruding in the protruding direction of the first claw portion so that the end face of the bending portion between the second connecting plate portion and the second anchor plate portion becomes its apex; and a first receiving blade plate portion and a second receiving blade plate portion rising from both ends of the mounting plate portion toward the outer surface of the mounting plate portion .

The embankment structure according to the present invention is an embankment structure in which an embankment panel is attached to an embankment foam resin block, and comprises the foam resin block, the embankment panel, and a mounting fixture for attaching the embankment panel to the foam resin block, wherein the mounting fixture comprises a fastener for attaching the panel to the embankment panel, a U-shaped mounting plate portion having a through hole for accommodating the fastener, a first connecting plate portion and a second connecting plate portion formed on both ends of the mounting plate portion, a first anchor plate portion formed by bending an end of the first connecting plate portion opposite to the mounting plate portion side toward the outer surface of the first connecting plate portion , and a second anchor plate portion formed by bending an end of the second connecting plate portion opposite to the mounting plate portion side toward the outer surface of the second connecting plate portion. a second anchor plate portion; a first claw portion that protrudes so that the end face of the bent portion between the first connecting plate portion and the first anchor plate portion becomes its peak; a second claw portion that protrudes in the protruding direction of the first claw portion so that the end face of the bent portion between the second connecting plate portion and the second anchor plate portion becomes its peak; and a first receiving blade plate portion and a second receiving blade plate portion that rise from both ends of the mounting plate portion toward the outer surface side of the mounting plate portion , wherein the foamed resin block has the first connecting plate portion and the second connecting plate portion, the first anchor plate portion and the second anchor plate portion, and the first claw portion and the second claw portion inserted therein, and the first receiving blade plate portion and the second receiving blade plate portion come into contact with the front surface of the foamed resin block that faces the embankment panel.

The embankment construction method of the present invention is a method for attaching an embankment panel to an embankment foam resin block using the mounting fixture of the first invention, and is characterized by comprising an insertion step of inserting the first connecting plate, the second connecting plate, the first anchor plate, the second anchor plate, the first claw, and the second claw into the foam resin block while bringing the first receiving blade plate and the second receiving blade plate into contact with the front of the foam resin block, and an attachment step of attaching the mounting plate and the embankment panel with the fasteners.

This invention makes it possible to place foam resin blocks for embankments in the designed position, making construction easier.

Below, an example of a mounting fixture, embankment structure, and embankment structure construction method as an embodiment of the present invention will be described with reference to the drawings.

(First embodiment: embankment structure 100)
As shown in FIGS. 1 and 2 , 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 or the like, and has an upper deck 91, such as a road, installed on top. The upper deck 91 is a concrete deck and has reinforcing bars (not shown) installed inside. The embankment structure 100 includes the foam resin blocks 7, the embankment panels 8, and mounting fixtures 1. The embankment structure 100 may also include the foam resin blocks 7, the embankment panels 8, and joint material 70 installed in the joints 75 between adjacent foam resin blocks 7. The joint material 70 may include a joint plate 79 installed across multiple foam resin blocks 7 adjacent in at least one of the vertical and horizontal directions, and mounting fixtures 1 for attaching the joint plate 79 to the foam resin blocks 7.

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. For example, 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 carry 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 embankment panel 8 is provided with a steel plate 81, for example, with a hat-shaped cross section, that forms the outer surface of the embankment panel 8. Holes are formed in the steel plate 81, forming the holes in the embankment panel 8. Fasteners that fasten the embankment panel 8 are provided in the holes formed in the steel plate 81. By fastening the fasteners to the steel plate 81, a fastening force acts on the steel plate 81, which makes it possible to prevent damage to the concrete portion of the embankment panel 8, for example, when fastening a concrete embankment panel 8 to the mounting fixture 1.

The fixture 1 is a metal fitting that attaches the embankment panel 8 to the foam resin block 7. The fixture 1 is inserted into either the top surface 73, bottom surface 74, or side surface 72 of the foam resin block 7. For example, four fixtures 1 are provided on one embankment panel 8, spaced apart in the vertical and horizontal directions. The fixture 1 can attach the embankment panel 8 at a distance from the front surface 71 of the foam resin block 7.

As shown in Figure 3, the fixture 1 is formed by bending a single steel plate with a thickness of approximately 0.5 mm to 4 mm. The fixture 1 includes an attachment portion 2 and an insertion portion 3.

The mounting portion 2 is used to attach at least one of the embankment panel 8 and the joint plate 79, and is provided on the outside of the foam resin block 7. The mounting portion 2 has a mounting plate portion 21, fasteners (bolts 25 and nuts 26), a first receiving blade plate portion 23, and a second receiving blade plate portion 24. The insertion portion 3 is connected to the mounting portion 2 and inserted into the foam resin block 7. The insertion portion 3 has a first connecting plate portion 31, a second connecting plate portion 41, a first anchor plate portion 32, a second anchor plate portion 42, a first claw portion 33, and a second claw portion 43.

The mounting plate 21 is U-shaped and has a main plate 21a to which the embankment panel 8 contacts, and a pair of side plate sections 21b bent from both ends of the main plate 21a. The main plate 21a has through holes 22 formed therein for bolts 25 used as fasteners. The main plate 21a is attached to the embankment panel 8 with the bolts 25 and nuts 26. The through holes 22 are elongated holes that extend in the direction in which the first claws 33 protrude. When the through holes 22 are elongated holes, the mounting position of the embankment panel 8 can be adjusted in the direction in which the elongated holes extend.

The bolt 25 may be, for example, an M8 or M10 bolt. The bolt 25 penetrates the embankment panel 8. The bolt 25 is spaced from the foam resin block 7. The bolt 25 has a threaded portion 25a formed at the tip of the shaft and a flat portion 25b formed between the threaded portion 25a and the head of the bolt 25. As a result, when the nut 26 is threaded onto the threaded portion 25a, the nut 26 is not threaded onto the flat portion 25b, allowing the bolt 25 to slide in the extension direction of the elongated through-hole 22. Note that the entire shaft of the bolt 25 may be made of the threaded portion 25a. In this case, when the nut 26 is threaded onto the threaded portion 25a, the bolt 25 can be fixed without sliding relative to the mounting plate 21.

A first notch 28 is formed on the end face of one side plate 21b opposite the protruding direction of the first claw 33, closer to the main plate 21a of the mounting plate 21 than the first receiving blade plate 23. A second notch 29 is formed on the end face of the other side plate 21b opposite the protruding direction of the second claw 43, closer to the main plate 21a of the mounting plate 21 than the second receiving blade plate 24. The first notch 28 and second notch 29 face each other.

A co-rotation prevention plate 5 is attached to the mounting plate 21. The co-rotation prevention plate 5 is formed, for example, by bending a single steel plate into a U-shape. The co-rotation prevention plate 5 is provided between the pair of side plates 21b and is arranged so that it can come into contact with at least one of the pair of side plates 21b. As a result, when the bolt 25 is screwed in, a reaction force is obtained from the co-rotation prevention plate 5 that is in contact with at least one of the pair of side plates 21b. This makes it possible to prevent co-rotation between the bolt 25 and nut 26 attached to the co-rotation prevention plate 5.

The co-rotation prevention plate portion 5 has a first prevention plate portion 51 and a pair of second prevention plate portions 53, 54. The first prevention plate portion 51 is provided in contact with the main plate portion 21a and has a through hole 52 formed therein for receiving a bolt 25 as a fastener. The second prevention plate portions 53, 54 are formed by bending both ends of the first prevention plate portion 51 and are provided opposite each other. At least one of the second prevention plate portions 53, 54 is provided in contact with at least one of the pair of side plate portions 21b.

The first connecting plate portion 31 and the second connecting plate portion 41 are formed on both ends of the mounting plate portion 21 and are flush with the side plate portion 21b of the mounting plate portion 21, facing each other.

The first anchor plate portion 32 is formed by bending the end of the first connecting plate portion 31 opposite the end facing the mounting plate portion 21. The second anchor plate portion 42 is formed by bending the end of the second connecting plate portion 41 opposite the end facing the mounting plate portion 21. The first anchor plate portion 32 and the second anchor plate portion 42 are arranged parallel to the main plate portion 21a.

The first claw portion 33 protrudes so that the end face of the bent portion between the first connecting plate portion 31 and the first anchor plate portion 32 forms the apex 33a. This facilitates insertion into the foamed resin block 7. The first claw portion 33 is formed in an L-shape along the first connecting plate portion 31 and the first anchor plate portion 32 when viewed from the protruding direction of the first claw portion 33. The first claw portion 33 may include at least one of a first connecting claw portion 34 that extends along the first connecting plate portion 31 and a first anchor claw portion 35 that extends along the first anchor plate portion 32. The first connecting claw portion 34 has an inclined portion 341 that slopes from the apex 33a and a flat portion 342 that is connected to the inclined portion 341 and is parallel to the protruding direction of the first claw portion 33. This facilitates insertion of the first connecting claw portion 34 into the foamed resin block 7. The first anchor claw 35 has an inclined portion 351 that slopes from the top 33a, and a flat portion 352 that connects to the inclined portion 351 and is parallel to the protruding direction of the first claw 33. This makes it easier to insert the first anchor claw 35 into the foam resin block 7.

The second claw portion 43 protrudes so that the end face of the bent portion between the second connecting plate portion 41 and the second anchor plate portion 42 forms the apex 43a. This allows for easy insertion into the foamed resin block 7. The second claw portion 43 protrudes in the protruding direction of the first claw portion 33. The second claw portion 43 is formed in an L-shape along the second connecting plate portion 41 and the second anchor plate portion 42 when viewed from the protruding direction of the second claw portion 43. The second claw portion 43 may include at least one of a second connecting claw portion 44 that extends along the second connecting plate portion 41 and a second anchor claw portion 45 that extends along the second anchor plate portion 42. The second connecting claw portion 44 has an inclined portion 441 that slopes from the apex 43a and a flat portion 442 that is connected to the inclined portion 441 and is parallel to the protruding direction of the second claw portion 43. This makes it easier to insert the second connecting claw portion 44 into the foamed resin block 7. The second anchor claw portion 45 has an inclined portion 451 that slopes from the top portion 43a, and a flat portion 452 that is connected to the inclined portion 451 and is parallel to the protruding direction of the second claw portion 43. This makes it easier to insert the second anchor claw portion 45 into the foamed resin block 7.

The first receiving blade plate portion 23 and the second receiving blade plate portion 24 rise from both ends of the mounting plate portion 21 and are provided in contact with the front surface 71 of the foam resin block 7. The first receiving blade plate portion 23 rises approximately vertically from the end of one side plate portion 21b of the mounting plate portion 21 toward the opposite side plate portion 21b. A hole 23a is formed in the first receiving blade plate portion 23. The second receiving blade plate portion 24 rises approximately vertically from the end of the other side plate portion 21b of the mounting plate portion 21 toward the opposite side plate portion 21b. A hole 24a is formed in the second receiving blade plate portion 24. The first receiving blade plate portion 23 and the second receiving blade plate portion 24 are provided parallel to the main plate portion 21a of the mounting plate portion 21. Reinforcing members such as anchors (not shown) can be driven into the holes 23a and 24a. By driving reinforcing members into holes 23a and 24a, the first receiving blade plate portion 23 and the second receiving blade plate portion 24 can be firmly fixed to the foam resin block 7.

The ends of the first receiving blade plate 23 and the second receiving blade plate 24 are positioned so as to protrude further than the apex 33a of the first claw 33 and the apex 43a of the second claw 43 in the protruding direction of the first claw 33. This allows the first receiving blade plate 23 and the second receiving blade plate 24 to be positioned in contact with the front surface 71 of the foamed resin block 7 when the apex 33a of the first claw 33 and the apex 43a of the second claw 43 contact the outer surface (e.g., the upper surface 73) of the foamed resin block 7. Therefore, when the mounting fixture 1 is inserted into the foamed resin block 7, the first receiving blade plate 23 and the second receiving blade plate 24 can be inserted with the first receiving blade plate 23 and the second receiving blade plate 24 in contact with the front surface 71 of the foamed resin block 7. In the present invention, at least one of the ends of the first receiving blade plate portion 23 and the second receiving blade plate portion 24 may be positioned so as to protrude further than the apex 33a of the first claw portion 33 and the apex 43a of the second claw portion 43 in the protruding direction of the first claw portion 33.

In addition, the embankment structure 100 has joint material 70 provided along the joints 75 between the foamed resin blocks 7. The joints 75 are formed, for example, by the upper surface 73 and the lower surface 74 of the foamed resin blocks 7 that are in contact with each other. The joints 75 are formed, for example, by the side surfaces 72 of the foamed resin blocks 7 that are in contact with each other.

The joint material 70 prevents deterioration of the foamed resin block 7 due to ultraviolet rays and other factors. The joint material 70 includes a fixture 1 and a joint plate 79. The fixture 1 can attach the joint plate 79 to the front surface 71 of the foamed resin block 7.

The joint plate 79 is fitted into the first notch 28 and the second notch 29 of the mounting fixture 1. The joint plate 79 is made of a steel plate, resin plate, or the like, with a thickness of approximately 0.5 mm to 4 mm. The joint plate 79 is formed by extending along the joints 75 between the foam resin blocks 7. The joint plate 79 is formed by bending both ends of the short side in the same direction. In this case, the rigidity of the joint plate 79 can be improved compared to when the joint plate 79 is a flat plate. Furthermore, when the short side ends of the joint plate 79 are bent, it is easier to insert the joint plate 79 into the first notch 28 and the second notch 29. The short side ends of the joint plate 79 may have grooves formed therein that fit into the mounting part 2. In this case, longitudinal movement of the joint plate 79 can be suppressed when the joint plate 79 is attached to the mounting part 2.

The first notch 28 and the second notch 29 are tapered, narrowing from the entrance side toward the back. This makes it easier to insert the joint plate 79 into the first notch 28 and the second notch 29.

<First embodiment: Construction method of embankment structure 100>
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 8 are attached to embankment foam resin blocks 7. The construction method for the embankment structure 100 involves attaching the embankment panels 8 to a plurality of foam resin blocks 7 arranged in the vertical and horizontal directions. The construction method for the embankment structure 100 includes, for example, an insertion process, an attachment process, and a joint plate installation process.

As shown in Figures 4 to 6, in the insertion process, the mounting fixture 1-1 is inserted into the lower foam resin block 7-1.

In more detail, first, as shown in Figures 4(a) and 4(b), in the insertion process, the top 33a of the first claw portion 33 of the fixture 1-1 and the top 43a of the second claw portion 43 of the fixture 1-1 are placed in contact with the upper surface 73 of the foamed resin block 7. At this time, the first receiving blade plate portion 23 and the second receiving blade plate portion 24 are placed in contact with the front surface 71 of the foamed resin block 7.

As shown in Figures 5 and 6, in the insertion process, the first receiving blade plate 23 and the second receiving blade plate 24 are brought into contact with the front surface 71 of the foamed resin block 7-1, while the first connecting plate 31, the second connecting plate 41, the first anchor plate 32, the second anchor plate 42, the first claw 33, and the second claw 43 are inserted into the upper surface 73 of the foamed resin block 7-1. As a result, the first connecting plate 31, the second connecting plate 41, the first anchor plate 32, the second anchor plate 42, the first claw 33, and the second claw 43 are inserted into the foamed resin block 7-1. In other words, the insertion portion 3 is inserted into the foamed resin block 7-1.

The first claw portion 33 protrudes so that the end face of the bent portion between the first connecting plate portion 31 and the first anchor plate portion 32 becomes the apex 33a, making it easy to insert into the foamed resin block 7-1. Similarly, the second claw portion 43 protrudes so that the end face of the bent portion between the first connecting plate portion 31 and the first anchor plate portion 32 becomes the apex 43a, making it easy to insert into the foamed resin block 7-1.

In addition, during the insertion process, the fixture 1-1 is inserted while the first receiving blade plate portion 23 and the second receiving blade plate portion 24 are in contact with the front surface 71 of the foam resin block 7-1, making it easy to insert the fixture 1-1 into the designed position.

When the mounting fixture 1-1 is inserted into the foam resin block 7-1, the first connecting plate portion 31, the second connecting plate portion 41, the first anchor plate portion 32, the second anchor plate portion 42, the first claw portion 33, and the second claw portion 43 are embedded in the foam resin block 7-1 and do not protrude from the side surface 72, top surface 73, or bottom surface 74 of the foam resin block 7-1. This prevents the mounting fixture 1-1 from interfering with other foam resin blocks 7 when the foam resin block 7 is installed in the vertical or horizontal directions. This makes it possible to place the foam resin block 7 for embankment in the designed position.

When the mounting fixture 1-1 is inserted into the foamed resin block 7-1, the main plate portion 21a of the mounting plate portion 21 faces the front surface 71 of the foamed resin block 7-1 at a position spaced apart from the front surface 71 of the foamed resin block 7-1. Furthermore, the first cutout portion 28 and the second cutout portion 29 are positioned on the outside of the foamed resin block 7-1.

Next, as shown in Figure 7, in the installation process, the mounting plate 21 of the mounting fixture 1-1 and the embankment panel 8-1 are attached using fasteners. In the installation process, the co-rotation prevention plate 5 is positioned between the first connecting plate 31 and the second connecting plate 41. Then, in the installation process, the first preventing plate 51 and the mounting plate 21 are attached to the embankment panel 8-1 using bolts 25 and nuts 26. The second preventing plate portions 53, 54 are provided in contact with the pair of side plate portions 21b, respectively. As a result, when the bolt 25 is screwed in, a reaction force is obtained from the co-rotation prevention plate 5 in contact with at least one of the pair of side plate portions 21b. This prevents co-rotation between the bolt 25 and nut 26 provided on the co-rotation prevention plate 5.

Next, as shown in Figure 8, in the joint plate installation process, a joint plate 79 is installed in the first notch 28 and second notch 29 of the mounting fixture 1-1 inserted into the foam resin block 7-1.

As shown in FIG. 9, in the insertion process, the mounting fixture 1-2 is inserted into the underside 74 of the upper foam resin block 7-2, which is located above the foam resin block 7-1. Inserting the mounting fixture 1-2 into the underside 74 of the foam resin block 7-2 is similar to inserting the mounting fixture 1-1 into the upper side 73 of the lower foam resin block 7-1, so a detailed description will be omitted. When the mounting fixture 1-2 is inserted into the foam resin block 7-2, the first connecting plate portion 31, the second connecting plate portion 41, the first anchor plate portion 32, the second anchor plate portion 42, the first claw portion 33, and the second claw portion 43 are embedded in the foam resin block 7-2 and do not protrude from the side surface 72, upper surface 73, or lower surface 74 of the foam resin block 7-2. This prevents the mounting fixture 1-2 from interfering with other foam resin blocks 7 when the foam resin block 7 is installed in the vertical and horizontal directions. This makes it possible to place the foam resin blocks 7 for embankment in the designed position.

Then, in the installation process, the embankment panel 8-2 is attached to the mounting plate portion 21 of the mounting fixture 1-2, which is inserted into the underside 74 of the upper foam resin block 7-2, using bolts 25 and nuts 26. The installation of the embankment panel 8-2 is similar to the installation of the embankment panel 8-1, so a detailed explanation will be omitted.

Then, in the joint plate installation process, foam resin block 7-2 is placed above foam resin block 7-1. In the joint plate installation process, when foam resin block 7-2 is placed above foam resin block 7-1, joint plate 79 attached to fixture 1-1 is placed in the first notch 28 and second notch 29 of fixture 1-2 inserted into foam resin block 7-2. In this way, joint plate 79 is installed so as to straddle foam resin blocks 7-1 and 7-2.

In this way, the insertion process, attachment process, and joint plate installation process are repeated. This completes one example of a construction method for an embankment structure 100. Note that in the above-described embodiment, the embankment panel 8-2 was attached to the fixture 1-2 inserted into the foamed resin block 7-2 before the joint plate 79 was installed, but the embankment panel 8-2 may also be attached after the joint plate 79 is installed on the fixture 1-2 inserted into the foamed resin block 7-2.

In this embodiment, the first claw 33 protrudes so that the end face of the bent portion between the first connecting plate 31 and the first anchor plate 32 forms the apex 33a, and the second claw 43 protrudes along the protruding direction of the first claw 33 so that the end face of the bent portion between the second connecting plate 41 and the second anchor plate 42 forms the apex. This ensures that when the fixture 1 is inserted into the foamed resin block 7, the fixture 1 does not protrude from the side surface 72, top surface 73, or bottom surface 74 of the foamed resin block 7. Therefore, when multiple foamed resin blocks 7 are installed adjacent to each other in the vertical and horizontal directions, the fixture 1 inserted into one foamed resin block 7 can be prevented from interfering with other adjacent foamed resin blocks 7. As a result, it is possible to position the foamed resin blocks for embankment construction as designed.

In this embodiment, the first claw portion 33 protrudes so that the end face of the bent portion between the first connecting plate portion 31 and the first anchor plate portion 32 becomes the apex 33a, making it easy to insert into the foamed resin block 7-1. Similarly, the second claw portion 43 protrudes so that the end face of the bent portion between the first connecting plate portion 31 and the first anchor plate portion 32 becomes the apex 43a, making it easy to insert into the foamed resin block 7-1. This makes installation easy.

In particular, in this embodiment, the first claw portion 33 has a first connecting claw portion 34 aligned with the first connecting plate portion 31 and a first anchor claw portion 35 aligned with the first anchor plate portion 32. The second claw portion 43 has a second connecting claw portion 44 aligned with the second connecting plate portion 41 and a second anchor claw portion 45 aligned with the second anchor plate portion 42. In this case, the first claw portion 33 and the second claw portion 43 have a bent shape, such as an angled shape, which improves the strength of the claw. Therefore, breakage of the claw is suppressed and insertion is made easier not only for foamed resin blocks with relatively low true densities (approximately 12 kg/ ^m3 to 30 kg/ ^m3 ) but also for foamed resin blocks (buoyancy control blocks) with relatively high true densities (approximately 46 kg/ ^m3 to 70 kg/ ^m3 ). This makes it possible to safely attach buoyancy control blocks to wall surfaces, which were difficult to install with conventional mounting fixtures.

In this embodiment, the first anchor plate 32 is formed by bending the end of the first connecting plate 31 opposite the mounting plate 21, and the second anchor plate 42 is formed by bending the end of the second connecting plate 41 opposite the mounting plate 21. As a result, when the embankment panel 8 is attached to the fixture 1, the first anchor plate 32 and the second anchor plate 42 act as pressure-receiving surfaces, preventing the panel from being pulled out toward the front surface 71 of the foamed resin block 7. This prevents the embankment panel 8 from falling off.

In this embodiment, the first claw portion 33 has a first anchor claw portion 35 that fits along the first anchor plate portion 32, and the second claw portion 43 has a second anchor claw portion 45 that fits along the second anchor plate portion 42. As a result, when the embankment panel 8 is attached to the mounting fixture 1, the first anchor claw portion 35 and the second anchor claw portion 45 act as pressure-receiving surfaces, preventing the panel from being pulled out toward the front surface 71 of the foam resin block 7. This prevents the embankment panel 8 from falling off.

In this embodiment, the mounting plate 21 is provided with a first receiving blade plate 23 and a second receiving blade plate 24 that rise from both ends. This allows the mounting fixture 1 to be inserted into the foamed resin block 7 while the first receiving blade plate 23 and the second receiving blade plate 24 are in contact with the front surface 71 of the foamed resin block 7. This makes it easier to insert the mounting fixture 1 into the designed position, facilitating installation.

Furthermore, as shown in FIG. 10, in the embankment structure 100, the mounting fixture 1-1 inserted into the foam resin block 7-1 tends to rotate in the direction of arrow R in the figure, with the left-right direction as its axis of rotation, due to the weight of the embankment panel 8-1. In this regard, this embodiment is equipped with a first receiving blade plate portion 23 and a second receiving blade plate portion 24 that rise from both ends of the mounting plate portion 21. As a result, the first receiving blade plate portion 23 and the second receiving blade plate portion 24, which are in contact with the front surface 71 of the foam resin block 7, become pressure-receiving surfaces, preventing the mounting fixture 1 from rotating in the direction of arrow R in the figure. This makes it possible to further prevent the mounting fixture 1 from being pulled out toward the front surface 71 of the foam resin block 7.

In this embodiment, at least one of the ends of the first receiving blade plate 23 and the second receiving blade plate 24 is positioned to protrude further than the apex 33a of the first claw 33 and the apex 43a of the second claw 43 in the protruding direction of the first claw 33. This allows at least one of the first receiving blade plate 23 and the second receiving blade plate 24 to be positioned in contact with the front surface 71 of the foamed resin block 7 when the apex 33a of the first claw 33 and the apex 43a of the second claw 43 contact the outer surface (e.g., the upper surface 73) of the foamed resin block 7. Therefore, when inserting the fixture 1 into the foamed resin block 7, the first claw 33 and the second claw 43 can be inserted with the first receiving blade plate 23 and the second receiving blade plate 24 in contact with the front surface 71 of the foamed resin block 7. This makes it easier to insert the fixture 1 into the designed position of the foamed resin block 7.

In this embodiment, the through holes 22 are elongated holes. This allows the embankment panel 8 to be adjusted and installed at the desired position on-site. This improves the ease of installation of the embankment panel 8.

Also, as shown in Figure 10, in the embankment structure 100, the embankment panel 8-1 is attached using mounting fixtures 1-1 and 1-3. The fastener of the upper mounting fixture 1-1 has a bolt 25 whose shank consists only of a threaded portion 25a. In this case, the fastener of mounting fixture 1-1 can be fixed so as not to slide relative to the mounting plate portion 21. The fastener of the lower mounting fixture 1-3 has a bolt 25 whose shank consists of a threaded portion 25a and a flat portion 25b. In this case, the fastener of mounting fixture 1-3 is configured to be slidable along the extension direction of the elongated through-hole 22.

Here, compressive deformation occurs in the foamed resin block 7 due to the load on top, and there is concern that the compressive deformation of the foamed resin block 7 may cause deformation of the embankment panel 8. In this regard, in this embodiment, of the mounting fixtures 1-1 and 1-3 spaced apart in the vertical direction on one embankment panel 8-1, the fastener of mounting fixture 1-1 is fixed to the mounting plate portion 21 of mounting fixture 1-1, and the fastener of mounting fixture 1-3 is configured to be able to slide along the elongated through-hole 22. This makes it possible to suppress deformation of the embankment panel 8-1 due to compressive deformation of the foamed resin block 7. As a result, damage to the embankment panel 8-1 can be suppressed.

In the present invention, when the fastener of fixture 1-1 is configured to be slidable, the fastener of fixture 1-3 may be fixed so as not to slide.In the present invention, the fasteners of fixtures 1-1 and 1-3 may be fixed so as not to slide.

In this embodiment, the first claw 33 has inclined portions 341, 351 that are inclined from the top 33a, and flat portions 342, 352 that extend from the inclined portions 341 parallel to the protruding direction of the first claw 33. This makes it even easier to insert the first claw 33 into the foam resin block 7. This makes installation even easier.

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 removed, and maintenance is not possible. In this regard, this embodiment uses bolts 25 that penetrate the embankment panels 8 as fasteners. This makes it possible to control the mounting strength of the bolts 25 with torque. This makes it possible to improve the safety of the embankment structure.

In this embodiment, the embankment panel 8 has bolts 25 that penetrate through it. This allows the bolts 25 to be attached and detached. This makes it easy to perform maintenance on the embankment structure 100.

In addition, this embodiment has bolts 25 that penetrate the embankment panel 8. This allows fine adjustments to the installation position of the embankment panel 8 even after it has been installed.

In this embodiment, the mounting fixture 1 is formed by bending a single plate material. This allows the thickness and material of the plate 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.

In this embodiment, the co-rotation prevention plate 5 is provided between the pair of side plate portions 21b and is capable of contacting at least one of the pair of side plate portions 21b. As a result, when the bolt 25 is screwed in, a reaction force is obtained from the co-rotation prevention plate 5 that is in contact with at least one of the pair of side plate portions 21b. This makes it possible to prevent co-rotation between the bolt 25 and nut 26 provided on the co-rotation prevention plate 5.

In conventional embankment structures, the embankment panel is installed in contact with the front of the foam resin block. This allows rainwater to drain along the front side of the embankment panel. This tends to cause deterioration and dirt on the surface of the embankment panel due to rainwater, which detracts from the aesthetic appeal. In this embodiment, the mounting fixture 1 attaches the embankment panel 8 to a position spaced apart from the foam resin block 7. This creates a space between the embankment panel 8 and the foam resin block 7. This allows rainwater to drain between the embankment panel 8 and the foam resin block 7. As a result, deterioration and dirt on the surface of the embankment panel 8 due to rainwater can be suppressed, and the aesthetic appeal can be maintained.

In conventional embankment structures, the embankment panel is placed in contact with the front of the foam resin block. This means that when the temperature is high, the heat from the foam resin block, which has high insulating properties, is transferred to the embankment panel. This raises concerns about deformation of the embankment panel due to heat. In this embodiment, the mounting fixture 1 attaches the embankment panel 8 to a position spaced apart from the foam resin block 7. This creates a space between the embankment panel 8 and the foam resin block 7. This creates an air gap between the embankment panel 8 and the foam resin block 7, which reduces the transfer of heat from the foam resin block 7 to the embankment panel 8. This reduces deformation of the embankment panel 8.

In addition, in this embodiment, the mounting fixture 1 attaches the embankment panel 8 at a position spaced apart from the foam resin block 7. This creates a space between the embankment panel 8 and the foam resin block 7. This creates an air layer between the embankment panel 8 and the foam resin block 7, improving fire resistance.

In this embodiment, the fixture 1 has an attachment portion 2 that is positioned on the outside of the foam resin block 7 and to which a joint plate 79 is attached, and an insertion portion 3 that is connected to the attachment portion 2 and inserted into the foam resin block 7. This allows the foam resin blocks 7 to be lined up in contact with each other without sandwiching joint material between them, and the foam resin blocks 7 can be installed in the designed position.

In conventional embankment structures, the joints between foam resin blocks are sometimes caulked to prevent deterioration due to ultraviolet rays and other factors. In this case, there are no gaps at the joints between the foam resin blocks, resulting in low heat dissipation from the joints. This means that the heat from the highly insulating foam resin blocks is transferred to the embankment panel. This raises concerns about deformation of the embankment panel due to the heat. In this embodiment, the mounting fixture 1 has an attachment section 2 that is positioned on the outside of the foam resin block 7 and to which a joint plate 79 is attached, and an insertion section 3 that is connected to the attachment section 2 and inserted into the foam resin block 7. This eliminates the need for caulking the joints 75. This ensures heat dissipation from the joints 75 and prevents deformation of the embankment panel 8.

In conventional embankment structures, to prevent deterioration due to ultraviolet rays and other factors, resin buffer material is adhered to the periphery of each embankment panel with adhesive, and the buffer material on adjacent embankment panels is brought into contact with each other to cover the joints of the foam resin blocks. In this case, it takes time for the adhesive to dry, and in the event of rain or other factors, the adhesive cannot be applied, making construction time consuming. In this regard, in this embodiment, the mounting fixture 1 has a mounting portion 2 that is positioned on the outside of the foam resin block 7 and to which a joint plate 79 is attached, and an insertion portion 3 that is connected to the mounting portion 2 and inserted into the foam resin block 7. This eliminates the need to install buffer material on the periphery of the embankment panel 8 via adhesive, making construction easier.

In this embodiment, the joint plate 79 is attached to the opposing first and second notches 28 and 29 of the fixture 1-1 provided on the foam resin block 7-1. This allows the joint plate 79 to be inserted into the first and second notches 28 and 29. This makes it easy to install the joint plate 79.

(Second embodiment: embankment structure 100)
Next, an example of an embankment structure 100 according to a second embodiment will be described. Detailed description of the same configuration as in the first embodiment will be omitted below.

As shown in Figure 11, the embankment structure 100 in the second embodiment further includes a plurality of foam resin blocks 7 spaced apart in the vertical direction, an intermediate deck 92 provided between the upper and lower foam resin blocks 7, and a shear stop plate 94 provided across the intermediate deck 92 and the foam resin block 7 above the intermediate deck 92. The mounting fixture 1 provided on the upper foam resin block 7 of the intermediate deck 92 is inserted above the shear stop plate 94 from the side of the upper foam resin block 7.

The intermediate deck 92 is, for example, a concrete deck. The shear stop plates 94 are fixed to the intermediate deck 92 via anchors 93. The shear stop plates 94 are, for example, flat steel plates with a thickness of approximately 0.5 mm to 4 mm. The shear stop plates 94 may be formed to be longer than the width of the foam resin blocks 7 in the left-right direction.

(Second embodiment: construction method of embankment structure 100)
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 8 are attached to embankment foam resin blocks 7. The construction method for the embankment structure 100 involves attaching the embankment panels 8 to a plurality of foam resin blocks 7 arranged in the vertical and horizontal directions. The construction method for the embankment structure 100 includes, for example, an insertion process, an attachment process, and a stopper plate installation process.

As shown in Figure 12, in the insertion process, the mounting fixture 1-1 is inserted into the lower foam resin block 7-1, as in the first embodiment.

Then, as in the first embodiment, in the installation process, the mounting plate portion 21 and the embankment panel 8-1 are attached using bolts 25 and nuts 26.

Then, as shown in Figure 13, in the insertion process, the mounting fixture 1-2 is inserted into the side surface 72 of the upper foamed resin block 7-2. In the insertion process, the first receiving blade plate portion 23 and the second receiving blade plate portion 24 are brought into contact with the front surface 71 of the foamed resin block 7-1, while the first connecting plate portion 31, the second connecting plate portion 41, the first anchor plate portion 32, the second anchor plate portion 42, the first claw portion 33, and the second claw portion 43 are inserted into the side surface 72 of the foamed resin block 7-1. As a result, the first connecting plate portion 31, the second connecting plate portion 41, the first anchor plate portion 32, the second anchor plate portion 42, the first claw portion 33, and the second claw portion 43 are inserted into the foamed resin block 7-2. When the mounting fixture 1-2 is inserted into the foam resin block 7-2, the first connecting plate 31, the second connecting plate 41, the first anchor plate 32, the second anchor plate 42, the first claw 33, and the second claw 43 are embedded in the foam resin block 7-2 and do not protrude from the side surface 72, top surface 73, or bottom surface 74 of the foam resin block 7-2. This prevents the mounting fixture 1-2 from interfering with other foam resin blocks 7 when the foam resin block 7 is installed vertically or horizontally. This makes it possible to position the embankment foam resin block 7 in the designed position. Note that during the insertion process, the mounting fixture 1-2 may be inserted into the bottom surface 74 of the upper foam resin block 7-2.

Then, as shown in Figure 14, in the insertion process, an intermediate deck 92 is placed above the foamed resin block 7-1, and a foamed resin block 7-2 is placed above the intermediate deck 92.

Then, in the installation process, the embankment panel 8-2 is attached to the mounting plate portion 21 of the mounting fixture 1-2, which is inserted into the side surface 72 of the upper foam resin block 7-2, using bolts 25 and nuts 26. The installation of the embankment panel 8-2 is similar to the installation of the embankment panel 8-1.

Then, as shown in Figure 15, in the shear stop plate installation process, the shear stop plate 94 is placed across the intermediate deck 92 and the foam resin block 7-2 above the intermediate deck 92, and the shear stop plate 94 is fixed to the intermediate deck 92 via anchors 93.

In this way, the insertion process, attachment process, and shear stop plate installation process are repeated. This completes one example of a construction method for the embankment structure 100. Note that the shear stop plate installation process may be performed before the insertion process and attachment process.

In conventional embankment structures, an intermediate deck may be installed between vertically spaced foam resin blocks. In such cases, when an earthquake occurs, a rocking phenomenon occurs in which the foam resin blocks float up, potentially causing the foam resin blocks to shift. In this regard, this embodiment includes multiple vertically spaced foam resin blocks 7, embankment panels 8, mounting fixtures 1 that attach the embankment panels 8 at a distance from the foam resin blocks 7, an intermediate deck 92 installed between the upper foam resin block 7-2 and the lower foam resin block 7-1, and a shear stop plate 94 installed across the intermediate deck 92 and the foam resin block 7-2 above the intermediate deck 92. This prevents the foam resin blocks 7 from shifting due to an earthquake, further stabilizing the embankment structure 100.

In this embodiment, the fixture 1 attached to the foamed resin block 7 above the intermediate deck slab 92 is positioned above the anti-slip plate 94 and inserted from the side surface 72 of the foamed resin block 7. This prevents interference between the fixture 1 and the anti-slip plate 94.

(Third embodiment: embankment structure 100)
Next, an example of the embankment structure 100 in the third embodiment will be described.

As shown in Figure 16, the embankment structure 100 in the third embodiment further includes a plurality of foam resin blocks 7 spaced apart in the vertical direction, an intermediate deck 92 provided between the upper and lower foam resin blocks 7, and a shear stop plate 94 provided across the intermediate deck 92 and the foam resin block 7 adjacent to the intermediate deck 92. This shear stop plate 94 is provided across the upper and lower foam resin blocks 7 of the intermediate deck 92.

By using the mounting fixture 1 to create a gap between the foam resin block 7 and the embankment panel 8, a flange portion can be formed that rises from the main plate of the shear stop plate 94. For example, as shown in Figure 17, the shear stop plate 94 may be formed with a U-shaped cross section. By forming a flange portion that rises from the main plate of the shear stop plate 94 in this way, the section modulus of the shear stop plate 94 can be improved compared to when the shear stop plate 94 is a flat plate. As a result, the shear stop plate 94 can be formed with a shorter extension in the left-right direction compared to when the shear stop plate 94 is a flat plate.

(Fourth embodiment: mounting fixture 1)
Next, an example of the fixture 1 in the fourth embodiment will be described.

As shown in Figure 18, the shape of the co-rotation prevention plate portion 5 in the mounting fixture 1 of the fourth embodiment differs from that of the first embodiment.

The co-rotation prevention plate 5 is formed, for example, by bending a single steel plate into an L-shape. The co-rotation prevention plate 5 is provided between the pair of side plate portions 21b and is capable of contacting at least one of the pair of side plate portions 21b. As a result, when the bolt 25 is screwed in, a reaction force is obtained from the co-rotation prevention plate 5 that is in contact with at least one of the pair of side plate portions 21b, thereby preventing co-rotation between the bolt 25 and nut 26 provided on the co-rotation prevention plate 5.

The co-rotation prevention plate portion 5 has a first prevention plate portion 51 and a second prevention plate portion 53. The first prevention plate portion 51 is provided in contact with the main plate portion 21a of the mounting plate portion 21, and has a through hole 52 formed therein in which a bolt 25 serving as a fastener is provided. The second prevention plate portion 53 is formed by bending one end of the first prevention plate portion 51. The second prevention plate portion 53 is provided in contact with at least one of the pair of side plate portions 21b.

In this embodiment, the co-rotation prevention plate 5 is provided between the pair of side plate portions 21b and is capable of contacting at least one of the pair of side plate portions 21b. As a result, when the bolt 25 is screwed in, a reaction force is obtained from the co-rotation prevention plate 5 that is in contact with at least one of the pair of side plate portions 21b. This makes it possible to prevent co-rotation between the bolt 25 and nut 26 provided on the co-rotation prevention plate 5.

(Fifth embodiment: embankment structure 100)
Next, an example of the embankment structure 100 in the fifth embodiment will be described.

As shown in Figure 19, in the embankment structure 100 of the fifth embodiment, the first connecting plate portion 31 and the second connecting plate portion 41 of the mounting fixture 1 are formed at an incline with respect to the side plate portion 21b.

The first connecting plate portion 31 is formed by bending the portion of one side plate portion 21b where the first receiving blade plate portion 23 rises. When the first connecting plate portion 31 is bent, it may be bent between the first receiving blade plate portion 23 and the first anchor plate portion 32.

The second connecting plate portion 41 is formed by bending the portion of the other side plate portion 21b where the second receiving blade plate portion 24 rises. When the second connecting plate portion 41 is bent, it may be bent between the second receiving blade plate portion 24 and the second anchor plate portion 42.

In this embodiment, the first connecting plate portion 31 is bent between the first receiving blade plate portion 23 and the first anchor plate portion 32, and the second connecting plate portion 41 is bent between the second receiving blade plate portion 24 and the second anchor plate portion 42. As a result, when the embankment panel 8 is attached to the mounting fixture 1, the first connecting plate portion 31 and the second connecting plate portion 41 act as pressure-receiving surfaces, further preventing the panel from being pulled out toward the front surface 71 of the foamed resin block 7. This prevents the embankment panel 8 from falling off.

(Sixth embodiment: embankment structure 100)
Next, an example of the embankment structure 100 in the sixth embodiment will be described.

As shown in Figure 20, in the embankment structure 100 of the sixth embodiment, a folded portion 79a is formed on the joint plate 79 of the joint material 70. The joint plate 79 has a folded portion 79a formed by folding the steel plate, for example, by accordion folding. The folded portion 79a is positioned to protrude forward from the mounting plate portion 21, and is positioned between the lower embankment panel 8-1 and the upper embankment panel 8-2.

In this embodiment, the joint plate 79 has a folded portion 79a formed by folding the plate material. This makes it easier for the joint plate 79 to remain covering the joint portion 75 even if deformation occurs in the foamed resin block 7 or the like. This further reduces deterioration of the foamed resin block 7 due to ultraviolet rays and other factors.

In this embodiment, the joint plate 79 has a folded accordion-like portion 79a, which is positioned between the lower embankment panel 8-1 and the upper embankment panel 8-2. As a result, when the gap between the lower embankment panel 8-1 and the upper embankment panel 8-2 becomes smaller due to deformation of the foam resin block 7 or the like, the folded accordion-like joint plate 79 acts as a buffer and can come into contact with at least one of the lower embankment panel 8-1 and the upper embankment panel 8-2. This prevents direct contact between the lower embankment panel 8-1 and the upper embankment panel 8-2, thereby preventing damage to the embankment panel 8.

(Seventh embodiment: embankment structure 100)
Next, an example of the embankment structure 100 according to the seventh embodiment will be described. In the embankment structure 100 according to the seventh embodiment, the mounting fixture 1 according to the seventh embodiment is used.

As shown in Figure 21, in the attachment device 1 of the seventh embodiment, the insertion portion 3 has a third claw portion 36 that protrudes in the opposite direction from the first claw portion 33, and a fourth claw portion 46 that protrudes in the opposite direction from the second claw portion 43.

The third claw portion 36 protrudes so that the end face of the bent portion between the first connecting plate portion 31 and the first anchor plate portion 32 forms the apex 36a. This facilitates insertion into the foamed resin block 7. The third claw portion 36 is formed in an L-shape along the first connecting plate portion 31 and the first anchor plate portion 32 when viewed from the protruding direction of the third claw portion 36. The third claw portion 36 may include at least one of a third connecting claw portion 37 that extends along the first connecting plate portion 31 and a third anchor claw portion 38 that extends along the first anchor plate portion 32. The third connecting claw portion 37 has an inclined portion 371 that slopes from the apex 36a and a flat portion 372 that is connected to the inclined portion 371 and is parallel to the protruding direction of the third claw portion 36. This facilitates insertion of the third connecting claw portion 37 into the foamed resin block 7. The third anchor claw 38 has an inclined portion 381 that slopes from the top 36a, and a flat portion 382 that connects to the inclined portion 381 and is parallel to the protruding direction of the third anchor claw 36. This makes it easier to insert the third anchor claw 38 into the foam resin block 7.

The fourth claw portion 46 protrudes so that the end face of the bent portion between the second connecting plate portion 41 and the second anchor plate portion 42 forms the peak 46a. This allows for easy insertion into the foamed resin block 7. The fourth claw portion 46 protrudes in the protruding direction of the third claw portion 36. The fourth claw portion 46 is formed in an L-shape along the second connecting plate portion 41 and the second anchor plate portion 42 when viewed from the protruding direction of the fourth claw portion 46. The fourth claw portion 46 may include at least one of a fourth connecting claw portion 47 that extends along the second connecting plate portion 41 and a fourth anchor claw portion 48 that extends along the second anchor plate portion 42. The fourth connecting claw portion 47 has an inclined portion 471 that slopes from the peak 46a and a flat portion 472 that is connected to the inclined portion 471 and is parallel to the protruding direction of the fourth claw portion 46. This makes it easier to insert the fourth connecting claw portion 47 into the foam resin block 7. The fourth anchor claw portion 48 has an inclined portion 481 that slopes from the top portion 46a, and a flat portion 482 that is connected to the inclined portion 481 and is parallel to the protruding direction of the fourth claw portion 46. This makes it easier to insert the fourth anchor claw portion 48 into the foam resin block 7.

As shown in Figure 22, when the mounting fixture 1-1 is inserted into the foamed resin block 7-1, the first connecting plate 31, the second connecting plate 41, the first anchor plate 32, the second anchor plate 42, the first claw 33, and the second claw 43 are embedded in the foamed resin block 7-1. The third claw 36 and the fourth claw 46 are inserted into and embedded in another foamed resin block 7-2 adjacent to the foamed resin block 7-1. This prevents the mounting fixture 1-1 from interfering with other foamed resin blocks 7 when the foamed resin block 7 is installed vertically or horizontally. This makes it possible to place the foamed resin block 7 for embankment in the designed position.

In this embodiment, the fixture has a third claw 36 that protrudes in the opposite direction to the protruding direction of the first claw 33, and a fourth claw 46 that protrudes in the opposite direction to the protruding direction of the second claw 43. This allows the third claw 36 and fourth claw 46 to be inserted into another foamed resin block 7-2 adjacent to the foamed resin block 7-1 when the first claw 33 and second claw 43 are inserted into the foamed resin block 7-1. Therefore, when the foamed resin block 7 is installed vertically or horizontally, the fixture 1-1 can be prevented from interfering with the other foamed resin blocks 7. This allows the foamed resin block 7 for embankment use to be placed in the designed position.

In this embodiment, the third claw portion 36 and the fourth claw portion 46 are inserted into the foamed resin block 7-2 adjacent to the foamed resin block 7-1. This increases the pressure-receiving area of the foamed resin block 7, further preventing the foamed resin block 7 from being pulled out toward the front surface 71. This prevents the embankment panel 8 from falling off.

In this embodiment, the third claw portion 36 has a third anchor claw portion 38 that aligns with the first anchor plate portion 32, and the fourth claw portion 46 has a fourth anchor claw portion 48 that aligns with the second anchor plate portion 42. As a result, when the embankment panel 8 is attached to the mounting fixture 1, the third anchor claw portion 38 and the fourth anchor claw portion 48 act as pressure-receiving surfaces, preventing the panel from being pulled out toward the front surface 71 of the foam resin block 7. This prevents the embankment panel 8 from falling off.

In this embodiment, the third claw portion 36 has a third connecting claw portion 37 that fits along the first connecting plate portion 31 and a third anchor claw portion 38 that fits along the first anchor plate portion 32, and the fourth claw portion 46 has a fourth connecting claw portion 47 that fits along the second connecting plate portion 41 and a fourth anchor claw portion 48 that fits along the second anchor plate portion 42. This allows the third claw portion 36 and the fourth claw portion 46 to have a bent shape, such as an angled shape, which improves the strength of the claws. This reduces breakage of the claws and makes them easier to insert into the foam resin block 7.

(Eighth embodiment: embankment structure 100)
Next, an example of an embankment structure 100 according to the eighth embodiment will be described. In the embankment structure 100 according to the eighth embodiment, the fixture 1 according to the seventh embodiment described above is used, and the third claw portion 36 and the fourth claw portion 46 are embedded in the intermediate deck 92 adjacent to the foam resin block 7-1.

As shown in Figure 23, when the mounting fixture 1-1 is inserted into the foam resin block 7-1, the first connecting plate 31, the second connecting plate 41, the first anchor plate 32, the second anchor plate 42, the first claw 33, and the second claw 43 are embedded in the foam resin block 7-1. The third claw 36 and the fourth claw 46 are embedded in the intermediate deck 92 adjacent to the foam resin block 7-1. This prevents the mounting fixture 1-1 from interfering with other foam resin blocks 7 when the foam resin block 7 is installed in the vertical and horizontal directions. This makes it possible to place the foam resin block 7 for embankment in the designed position.

When embedding the third claw portion 36 and the fourth claw portion 46 in the intermediate deck 92, first insert the first connecting plate portion 31, the second connecting plate portion 41, the first anchor plate portion 32, the second anchor plate portion 42, the first claw portion 33, and the second claw portion 43 into the foamed resin block 7-1. At this time, the third claw portion 36 and the fourth claw portion 46 protrude from, for example, the top surface 73 of the foamed resin block 7. Then, concrete or the like is poured into the foamed resin block 7-1 to install the intermediate deck 92. This allows the third claw portion 36 and the fourth claw portion 46 to be embedded in the intermediate deck 92.

In this embodiment, the third claw portion 36 and the fourth claw portion 46 are embedded in the intermediate deck 92 adjacent to the foam resin block 7-1. This firmly connects the foam resin block 7 and the intermediate deck 92, preventing the foam resin block 7 from rocking during an earthquake. This prevents the foam resin block 7 from shifting due to an earthquake.
