Description

[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 greater 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. 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 portions, the foam resin blocks must be cut again, 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.

[0011] 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.

[0012] (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 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.

[0013] The foamed resin blocks 7 can be made of a foamed 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, for example, with the blocks offset vertically and horizontally. 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.

[0014] 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.

[0015] 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.

[0016] The embankment panel 8 is provided with a steel plate 81, for example, having a hat-shaped cross section, that forms the outer surface of the embankment panel 8. Holes are formed in the steel plate 81, which form the holes of 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, so that when fastening the embankment panel 8 made of concrete to the mounting fixture 1, for example, damage to the concrete portion of the embankment panel 8 can be suppressed.

[0017] 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 any of 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.

[0018] 3, the fixture 1 is formed by bending a single steel plate having a thickness of approximately 0.5 mm to 4 mm. The fixture 1 comprises a mounting portion 2 and an insertion portion 3.

[0019] The mounting portion 2 is for mounting at least one of the embankment panel 8 and the joint plate 79, and is provided on the outside of the foamed resin block 7. The mounting portion 2 has a mounting plate portion 21, bolts 25 and nuts 26 as fasteners, 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 is inserted into the foamed 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.

[0020] The mounting plate portion 21 is formed in a U-shape and has a main plate portion 21a to which the embankment panel 8 contacts, and a pair of side plate portions 21b bent from both ends of the main plate portion 21a. The main plate portion 21a is formed with a through hole 22 for installing a bolt 25 as a fastener. The main plate portion 21a is attached to the embankment panel 8 in contact with it using the bolt 25 and a nut 26. The through hole 22 is an elongated hole that extends in the direction in which the first claw portion 33 protrudes. When the through hole 22 is an elongated hole, the mounting position of the embankment panel 8 can be adjusted in the extension direction of the elongated hole.

[0021] As the bolt 25, for example, an M8 bolt, an M10 bolt, or the like is used. The bolt 25 is passed through 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, and therefore the bolt 25 can be configured to slide in the extension direction of the elongated through-hole 22. Note that the entire shaft of the bolt 25 may be configured as 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 portion 21.

[0022] A first notch 28 is formed on an end face of one side plate portion 21b opposite to the protruding direction of the first claw portion 33, closer to the main plate portion 21a of the mounting plate portion 21 than the first receive blade plate portion 23. A second notch 29 is formed on an end face of the other side plate portion 21b opposite to the protruding direction of the second claw portion 43, closer to the main plate portion 21a of the mounting plate portion 21 than the second receive blade plate portion 24. The first notch 28 and the second notch 29 face each other.

[0023] A co-rotation inhibiting plate 5 is attached to the mounting plate 21. The co-rotation inhibiting plate 5 is formed, for example, by bending a single steel plate into a U-shape. The co-rotation inhibiting plate 5 is provided between the pair of side plate portions 21b and is provided so as to be able to come into contact with 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 inhibiting plate 5 that is in contact with at least one of the pair of side plate portions 21b. Therefore, co-rotation of the bolt 25 and nut 26 provided on the co-rotation inhibiting plate 5 can be inhibited.

[0024] 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 in which a bolt 25 serving as a fastener is provided. 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.

[0025] 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 portions 21b of the mounting plate portion 21 and face each other.

[0026] The first anchor plate 32 is formed by bending the end of the first connecting plate 31 opposite the end on the mounting plate 21 side. The second anchor plate 42 is formed by bending the end of the second connecting plate 41 opposite the end on the mounting plate 21 side. The first anchor plate 32 and the second anchor plate 42 are arranged parallel to the main plate 21a.

[0027] 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. 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 is inclined 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 is inclined from the top 33a, and a flat portion 352 that is connected 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 foamed resin block 7.

[0028] 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 becomes the apex 43a. This facilitates 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 facilitates insertion of the second connecting claw portion 44 into the foamed resin block 7. The second anchor claw 45 has an inclined portion 451 that is inclined 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 43. This makes it easier to insert the second anchor claw 45 into the foamed resin block 7.

[0029] 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 foamed resin block 7. The first receiving blade plate portion 23 rises approximately vertically from an end of one side plate portion 21b of the mounting plate portion 21 toward the opposite side to the other 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 an end of the other side plate portion 21b of the mounting plate portion 21 toward the opposite side to the one 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 the reinforcing members into the 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 foamed resin block 7.

[0030] The end of the first receiving blade plate portion 23 and the end of the second receiving blade plate portion 24 are arranged at positions that protrude further than the tops 33a of the first claw portions 33 and the tops 43a of the second claw portions 43 in the protruding direction of the first claw portions 33. This allows the first receiving blade plate portion 23 and the second receiving blade plate portion 24 to be provided in contact with the front surface 71 of the foamed resin block 7 when the tops 33a of the first claw portions 33 and the tops 43a of the second claw portions 43 come into contact with the outer surface (e.g., the upper surface 73) of the foamed resin block 7. Therefore, when the fixture 1 is inserted into the foamed resin block 7, the first claw portions 33 and the second receiving blade plate portion 24 can be inserted in a state where 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 foamed resin block 7. In addition, in the present invention, at least one of the end of the first receiving blade plate portion 23 and the end of the second receiving blade plate portion 24 may be positioned at a position that protrudes more 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.

[0031] Furthermore, in the embankment structure 100, joint material 70 is provided along joints 75 between the foamed resin blocks 7. The joints 75 are formed, for example, by an upper surface 73 and a lower surface 74 of the foamed resin block 7 that are provided in contact with each other. The joints 75 are formed, for example, by side surfaces 72 of the foamed resin blocks 7 that are provided in contact with each other.

[0032] The joint material 70 prevents deterioration of the foamed resin block 7 due to ultraviolet rays and the like. The joint material 70 has a mounting fixture 1 and a joint plate 79. The mounting fixture 1 can attach the joint plate 79 to the front surface 71 side of the foamed resin block 7.

[0033] 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, a resin plate, or the like, having a thickness of approximately 0.5 mm to 4 mm. The joint plate 79 is formed by extending along the joint portion 75 between the foamed resin blocks 7. The joint plate 79 is formed by bending both ends of the joint plate 79 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 ends of the joint plate 79 in the short direction are bent, the joint plate 79 can be easily inserted into the first notch 28 and the second notch 29. The short end of the joint plate 79 may have a groove formed therein that fits into the mounting portion 2. In this case, longitudinal movement of the joint plate 79 can be suppressed when the joint plate 79 is attached to the mounting portion 2.

[0034] The first cutout portion 28 and the second cutout portion 29 are tapered so that the width decreases from the entrance side to the back side. This makes it easy to insert the joint plate 79 into the first cutout portion 28 and the second cutout portion 29.

[0035] <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 foamed resin blocks 7 for use in embankments. The construction method for the embankment structure 100 involves attaching the embankment panels 8 to a plurality of foamed 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.

[0036] As shown in FIGS. 4 to 6, in the insertion step, the mounting fixture 1-1 is inserted into the lower foamed resin block 7-1.

[0037] 4(a) and 4(b), in the insertion step, the tops 33a of the first claw portions 33 of the fixture 1-1 and the tops 43a of the second claw portions 43 of the fixture 1-1 are provided 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 provided in contact with the front surface 71 of the foamed resin block 7.

[0038] 5 and 6, in the insertion step, 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 while 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. 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. That is, the insertion portion 3 is inserted into the foamed resin block 7-1.

[0039] 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 becomes the apex 33a, which allows for easy insertion into the foamed resin block 7-1. Similarly, the second claw 43 protrudes so that the end face of the bent portion between the first connecting plate 31 and the first anchor plate 32 becomes the apex 43a, which allows for easy insertion into the foamed resin block 7-1.

[0040] In addition, in the insertion process, the mounting 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 foamed resin block 7-1, making it easy to insert the mounting fixture 1-1 into the designed position.

[0041] When the mounting fixture 1-1 is inserted into the foamed 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 foamed resin block 7-1 and do not protrude from the side surface 72, the top surface 73, or the bottom surface 74 of 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 in the vertical and horizontal directions. This makes it possible to place the foamed resin block 7 for embankment in the designed position.

[0042] 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. The first cutout portion 28 and the second cutout portion 29 are located on the outside of the foamed resin block 7-1.

[0043] Next, as shown in FIG. 7, in the mounting step, the mounting plate 21 of the mounting fixture 1-1 and the embankment panel 8-1 are attached using fasteners. In the mounting step, the co-rotation suppression plate 5 is disposed between the first connecting plate 31 and the second connecting plate 41. Then, in the mounting step, the first suppression plate 51 and the mounting plate 21 are attached to the embankment panel 8-1 using bolts 25 and nuts 26. The second suppression plate portions 53 and 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 suppression plate 5 in contact with at least one of the pair of side plate portions 21b. This makes it possible to suppress co-rotation between the bolts 25 and nuts 26 provided on the co-rotation suppression plate 5.

[0044] Next, as shown in FIG. 8, in the joint plate installation step, a joint plate 79 is installed in the first notch 28 and the second notch 29 of the fixture 1-1 inserted into the foamed resin block 7-1.

[0045] As shown in FIG. 9 , in the insertion process, the fixture 1-2 is inserted into the underside 74 of the upper foamed resin block 7-2, which is located above the foamed resin block 7-1. Inserting the fixture 1-2 into the underside 74 of the foamed resin block 7-2 is similar to inserting the fixture 1-1 into the upper side 73 of the lower foamed resin block 7-1, and therefore a detailed description thereof will be omitted. When the fixture 1-2 is inserted into the foamed 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 foamed resin block 7-2 and do not protrude from the side surface 72, the upper surface 73, or the lower surface 74 of the foamed resin block 7-2. This prevents the fixture 1-2 from interfering with other foamed resin blocks 7 when the foamed resin block 7 is installed vertically or horizontally. This allows the embankment foamed resin block 7 to be positioned as designed.

[0046] Then, in the mounting process, the embankment panel 8-2 is mounted 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, with bolts 25 and nuts 26. The mounting of the embankment panel 8-2 is similar to the mounting of the embankment panel 8-1, so a detailed explanation will be omitted.

[0047] Then, in the joint plate installation process, a foamed resin block 7-2 is provided above the foamed resin block 7-1. In the joint plate installation process, when the foamed resin block 7-2 is provided above the foamed resin block 7-1, a joint plate 79 attached to the fixture 1-1 is installed in the first notch 28 and second notch 29 of the fixture 1-2 inserted into the foamed resin block 7-2. In this way, the joint plate 79 is provided so as to straddle the foamed resin blocks 7-1 and 7-2.

[0048] In this way, the insertion process, the attachment process, and the joint plate installation process are repeated. This completes one example of a construction method for the embankment structure 100. In the above embodiment, the embankment panel 8-2 is attached to the fixture 1-2 inserted into the foamed resin block 7-2, and then the joint plate 79 is installed, but the embankment panel 8-2 may be attached after the joint plate 79 is installed on the fixture 1-2 inserted into the foamed resin block 7-2.

[0049] 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 becomes 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 becomes the apex. As a result, when the fastener 1 is inserted into the foamed resin block 7, the fastener 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 fastener 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 place the foamed resin blocks for embankment in the designed position.

[0050] 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, which allows for easy insertion 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, which allows for easy insertion into the foamed resin block 7-1. This makes installation easy.

[0051] In particular, in this embodiment, the first claw portion 33 has a first connecting claw portion 34 along the first connecting plate portion 31 and a first anchor claw portion 35 along the first anchor plate portion 32, and the second claw portion 43 has a second connecting claw portion 44 along the second connecting plate portion 41 and a second anchor claw portion 45 along 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 angle shape, which improves the strength of the claws. For this reason, the strength of the claws can be improved even when the concrete density is relatively low (12 kg / m 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) with a thickness of about 1 / 4" can be inserted more easily without damaging the nails. This makes it possible to safely attach buoyancy control blocks to walls, which was previously difficult to install with conventional mounting fixtures.

[0052] In this embodiment, the embankment panel 8 has a first anchor plate 32 formed by bending the end of the first connecting plate 31 opposite the mounting plate 21, and a second anchor plate 42 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 mounting fixture 1, the first anchor plate 32 and the second anchor plate 42 act as pressure-receiving surfaces and can prevent 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.

[0053] 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 foamed resin block 7. This prevents the embankment panel 8 from falling off.

[0054] In this embodiment, the mounting plate 21 is provided with a first receiving blade plate portion 23 and a second receiving blade plate portion 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 portion 23 and the second receiving blade plate portion 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.

[0055] 10, in the embankment structure 100, the mounting fixture 1-1 inserted into the foamed 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, in this embodiment, the first receiving blade plate portion 23 and the second receiving blade plate portion 24 are provided, which 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 foamed resin block 7, become pressure-receiving surfaces, and can suppress the tendency to rotate in the direction of arrow R in the figure. This makes it possible to further suppress the mounting fixture 1-1 from being pulled out toward the front surface 71 of the foamed resin block 7.

[0056] In this embodiment, at least one of the end of the first receiving blade plate 23 and the end of the second receiving blade plate 24 is disposed at a position that protrudes further than the tops 33a of the first and second claws 33 and 43a of the second claws 43 in the protruding direction of the first claws 33. As a result, when at least one of the tops 33a of the first and second claws 33 and 43a of the second claws 43 contacts the outer surface (e.g., the upper surface 73) of the foamed resin block 7, at least one of the first receiving blade plate 23 and the second receiving blade plate 24 can be provided in contact with the front surface 71 of the foamed resin block 7. Therefore, when the fixture 1 is inserted into the foamed resin block 7, the first and second claws 33 and 43 can be inserted in a state where the first and second receiving blade plate 23 and 24 contact the front surface 71 of the foamed resin block 7. As a result, the fixture 1 can be easily inserted into the designed position of the foamed resin block 7.

[0057] In this embodiment, the through holes 22 are elongated holes. This allows the embankment panel 8 to be adjusted and attached to a desired position on site. This makes it possible to improve the workability of the embankment panel 8.

[0058] As shown in FIG. 10, in the embankment structure 100, the embankment panel 8-1 is attached using mounting fixtures 1-1 and 1-3. In the fastener of the upper mounting fixture 1-1, the shank of the bolt 25 is composed only of a threaded portion 25a. In this case, the fastener of the mounting fixture 1-1 can be fixed so as not to slide relative to the mounting plate portion 21. In the fastener of the lower mounting fixture 1-3, the shank of the bolt 25 is composed of a threaded portion 25a and a flat portion 25b. In this case, the fastener of the mounting fixture 1-3 is configured to be slidable along the extension direction of the through-hole 22, which is an elongated hole.

[0059] Here, compressive deformation occurs in the foamed resin blocks 7 due to the load on top, and there is concern that the compressive deformation of the foamed resin blocks 7 will 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 blocks 7. As a result, damage to the embankment panel 8-1 can be suppressed.

[0060] In the present invention, when the fastener of mounting fixture 1-1 is configured to be slidable, the fastener of mounting fixture 1-3 may be fixed so as not to slide. In the present invention, the fasteners of mounting fixture 1-1 and mounting fixture 1-3 may be fixed so as not to slide.

[0061] In this embodiment, the first claw portion 33 has inclined portions 341, 351 that are inclined from the top portion 33a, and flat portions 342, 352 that extend from the inclined portions 341 in parallel to the protruding direction of the first claw portion 33. This makes it even easier to insert the first claw portion 33 into the foamed resin block 7, making installation even easier.

[0062] 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 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.

[0063] 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 possible to easily perform maintenance on the embankment structure 100.

[0064] Furthermore, in this embodiment, the embankment panel 8 has bolts 25 that are passed through it. This allows fine adjustment of the mounting position of the embankment panel 8 even after the embankment panel 8 has been mounted.

[0065] In this embodiment, the fixture 1 is formed by bending a single plate. This allows the thickness and material of the plate to be set. For example, if the foam 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.

[0066] In this embodiment, the co-rotation suppression plate 5 is provided between the pair of side plate portions 21b and is provided so as to be able to come into contact with 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 suppression plate 5 that is in contact with at least one of the pair of side plate portions 21b. As a result, co-rotation of the bolt 25 and nut 26 provided on the co-rotation suppression plate 5 can be suppressed.

[0067] 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 impairs the aesthetic appeal. In this regard, 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, it is possible to prevent deterioration and dirt on the surface of the embankment panel 8 due to rainwater, and maintain the aesthetic appeal.

[0068] 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 thermal insulation performance, is transferred to the embankment panel. This raises concerns about deformation of the embankment panel due to heat. In this regard, in this embodiment, the mounting fixture 1 attaches the embankment panel 8 to a position separated 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, which can suppress heat transfer from the foam resin block 7 to the embankment panel 8. This prevents deformation of the embankment panel 8.

[0069] In this embodiment, the mounting fixture 1 attaches the embankment panel 8 to a position spaced apart from the foamed resin block 7. This forms a space between the embankment panel 8 and the foamed resin block 7. This creates an air layer in the space between the embankment panel 8 and the foamed resin block 7, improving fire resistance.

[0070] In this embodiment, the fixture 1 has a mounting portion 2 that is disposed on the outside of the foamed 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 foamed resin block 7. This allows the foamed resin blocks 7 to be lined up in contact with each other without sandwiching any joint material between them, and the foamed resin blocks 7 to be installed in the designed position.

[0071] 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, no gaps are formed at the joints between the foam resin blocks, resulting in low heat dissipation from the joints. This allows the heat from the highly insulating foam resin blocks to be transferred to the embankment panel. This raises concerns about thermal deformation of the embankment panel. In this embodiment, the mounting fixture 1 includes 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 for caulking the joints 75. This ensures heat dissipation from the joints 75 and prevents deformation of the embankment panel 8.

[0072] 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 an adhesive, and the buffer material of adjacent embankment panels is brought into contact with each other to cover the joints between 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 longer. In this regard, in this embodiment, the mounting fixture 1 has a mounting portion 2 that is disposed 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. This simplifies construction.

[0073] In this embodiment, the joint plate 79 is attached to the first notch 28 and the second notch 29 facing each other of the fixture 1-1 provided on the foamed resin block 7-1. This allows the joint plate 79 to be inserted into the first notch 28 and the second notch 29. This makes it easy to install the joint plate 79.

[0074] (Second embodiment: embankment structure 100) Next, an example of an embankment structure 100 according to the second embodiment will be described. Detailed description of the same configuration as in the first embodiment will be omitted below.

[0075] 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 foam resin block 7 and the lower foam resin block 7, and a stopper 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 stopper plate 94 from the side of the upper foam resin block 7.

[0076] The intermediate floor slab 92 is, for example, a concrete floor slab. The displacement stopper plates 94 are fixed to the intermediate floor slab 92 via anchors 93. The displacement stopper plates 94 are, for example, flat steel plates with a thickness of about 0.5 mm to 4 mm. The displacement stopper plates 94 may be formed to be longer than the width of the foamed resin blocks 7 in the left-right direction.

[0077] (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 foam resin blocks 7 for use in embankments. 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.

[0078] As shown in FIG. 12, in the same manner as in the first embodiment, in the insertion step, the fixture 1-1 is inserted into the lower foamed resin block 7-1.

[0079] Then, in the same manner as in the first embodiment, the mounting plate portion 21 and the embankment panel 8-1 are mounted with the bolts 25 and nuts 26 in the mounting step.

[0080] 13, in the insertion step, the mounting fixture 1-2 is inserted into the side surface 72 of the upper foamed resin block 7-2. In the insertion step, 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, and 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 foamed 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 foamed resin block 7-2 and do not protrude from the side surface 72, the top surface 73, or the bottom surface 74 of the foamed resin block 7-2. This prevents the mounting fixture 1-2 from interfering with other foamed resin blocks 7 when the foamed resin block 7 is installed in the vertical and horizontal directions. This makes it possible to position the foamed resin block 7 for embankment in the designed position. Note that in the insertion process, the mounting fixture 1-2 may be inserted into the bottom surface 74 of the upper foamed resin block 7-2.

[0081] Then, as shown in FIG. 14, in the inserting step, an intermediate floor slab 92 is provided above the foamed resin block 7-1, and a foamed resin block 7-2 is provided above the intermediate floor slab 92.

[0082] Then, in the mounting process, the embankment panel 8-2 is mounted to the mounting plate portion 21 of the mounting fixture 1-2 inserted into the side surface 72 of the upper foam resin block 7-2 with bolts 25 and nuts 26. The mounting of the embankment panel 8-2 is similar to the mounting of the embankment panel 8-1.

[0083] Then, as shown in Figure 15, in the anti-slip plate installation process, an anti-slip plate 94 is placed so as to straddle the intermediate deck 92 and the foam resin block 7-2 above the intermediate deck 92, and the anti-slip plate 94 is fixed to the intermediate deck 92 via anchors 93.

[0084] In this way, the inserting step, the attaching step, and the shear stop plate installing step are repeated, completing one example of the construction method for the embankment structure 100. Note that the shear stop plate installing step may be performed before the inserting step and the attaching step.

[0085] In conventional embankment structures, an intermediate deck may be installed between vertically spaced foam resin blocks. In this case, a rocking phenomenon occurs in which the foam resin blocks float up during an earthquake, potentially causing the foam resin blocks to shift. In this regard, the present embodiment includes multiple vertically spaced foam resin blocks 7, an embankment panel 8, a fixture 1 for attaching the embankment panel 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. This further stabilizes the embankment structure 100.

[0086] In this embodiment, the fixture 1 provided on the foamed resin block 7 above the intermediate deck 92 is positioned above the anti-slip plate 94 and inserted from the side surface 72 of the foamed resin block 7. This makes it possible to prevent interference between the fixture 1 and the anti-slip plate 94.

[0087] (Third embodiment: embankment structure 100) Next, an example of the embankment structure 100 in the third embodiment will be described.

[0088] 16, the embankment structure 100 in the third embodiment further includes a plurality of foamed resin blocks 7 spaced apart in the vertical direction, an intermediate deck 92 provided between the upper and lower foamed resin blocks 7, and a stopper plate 94 provided across the intermediate deck 92 and the foamed resin block 7 adjacent to the intermediate deck 92. The stopper plate 94 is provided across the upper and lower foamed resin blocks 7 of the intermediate deck 92.

[0089] By using the mounting fixture 1 to form a gap between the foam resin block 7 and the embankment panel 8, it is possible to form a flange portion that rises from the main plate of the shear stop plate 94. For example, as shown in FIG. 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. Therefore, 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.

[0090] (Fourth embodiment: fixture 1) Next, an example of the fixture 1 in the fourth embodiment will be described.

[0091] As shown in FIG. 18, in the mounting fixture 1 of the fourth embodiment, the shape of the co-rotation suppression plate portion 5 differs from that of the first embodiment.

[0092] The co-rotation inhibiting plate 5 is formed, for example, by bending a single steel plate into an L-shape. The co-rotation inhibiting plate 5 is provided between the pair of side plate portions 21b and is provided so as to be able to come into contact with 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 inhibiting plate 5 that is in contact with at least one of the pair of side plate portions 21b, so that co-rotation of the bolt 25 and nut 26 provided on the co-rotation inhibiting plate 5 can be inhibited.

[0093] 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.

[0094] In this embodiment, the co-rotation suppression plate 5 is provided between the pair of side plate portions 21b and is provided so as to be able to come into contact with 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 suppression plate 5 that is in contact with at least one of the pair of side plate portions 21b. As a result, co-rotation of the bolt 25 and nut 26 provided on the co-rotation suppression plate 5 can be suppressed.

[0095] (Fifth embodiment: embankment structure 100) Next, an example of the embankment structure 100 in the fifth embodiment will be described.

[0096] As shown in FIG. 19, in an embankment structure 100 in the fifth embodiment, the first connecting plate portion 31 and the second connecting plate portion 41 of the mounting fixture 1 are formed so as to be inclined with respect to the side plate portion 21b.

[0097] The first connecting plate portion 31 is formed by bending the first side plate portion 21b from a rising portion of the first receiving blade plate portion 23. 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.

[0098] The second connecting plate portion 41 is formed by bending the other side plate portion 21b from a rising portion of the second receiving blade plate portion 24. 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.

[0099] 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 become pressure-receiving surfaces, further preventing the panel from being pulled out toward the front surface 71 of the foamed resin block 7. This makes it possible to prevent the embankment panel 8 from falling off.

[0100] (Sixth embodiment: embankment structure 100) Next, an example of the embankment structure 100 according to the sixth embodiment will be described.

[0101] As shown in Fig. 20, in the embankment structure 100 of the sixth embodiment, a folded portion 79a is formed in the joint plate 79 of the joint material 70. The folded portion 79a is formed by folding back a steel plate, for example, by accordion folding, in the joint plate 79. 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.

[0102] In this embodiment, the joint plate 79 has a folded portion 79a formed by folding back the plate material. This makes it easier for the joint plate 79 to be maintained so as to cover 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 or the like.

[0103] In this embodiment, the joint plate 79 has a folded-back portion 79a that is folded in an accordion pattern, and the folded-back portion 79a is disposed 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 accordion-folded 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 the lower embankment panel 8-1 and the upper embankment panel 8-2 from coming into direct contact with each other, thereby preventing damage to the embankment panel 8.

[0104] (Seventh embodiment: embankment structure 100) Next, an example of the embankment structure 100 in the seventh embodiment will be described. In the embankment structure 100 in the seventh embodiment, the mounting fixture 1 in the seventh embodiment is used.

[0105] As shown in Figure 21, in the mounting fixture 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.

[0106] 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 becomes the apex 36a. This facilitates insertion into the foamed resin block 7. The third claw portion 36 is formed along the first connecting plate portion 31 and the first anchor plate portion 32 in an L-shape 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 is aligned with the first connecting plate portion 31 and a third anchor claw portion 38 that is aligned with the first anchor plate portion 32. The third connecting claw portion 37 has an inclined portion 371 that is inclined 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 is inclined from the top portion 36a, and a flat portion 382 that is connected 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 foamed resin block 7.

[0107] The fourth claw 46 protrudes so that the end face of the bent portion between the second connecting plate 41 and the second anchor plate 42 forms a peak 46a. This facilitates insertion into the foamed resin block 7. The fourth claw 46 protrudes in the protruding direction of the third claw 36. The fourth claw 46 is formed in an L-shape along the second connecting plate 41 and the second anchor plate 42 when viewed from the protruding direction of the fourth claw 46. The fourth claw 46 may include at least one of a fourth connecting claw 47 that extends along the second connecting plate 41 and a fourth anchor claw 48 that extends along the second anchor plate 42. The fourth connecting claw 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 46. This facilitates insertion of the fourth connecting claw 47 into the foamed resin block 7. The fourth anchor claw 48 has an inclined portion 481 that is inclined 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 46. This makes it easier to insert the fourth anchor claw 48 into the foamed resin block 7.

[0108] As shown in FIG. 22, when the mounting fixture 1-1 is inserted into a 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 allows the embankment foamed resin block 7 to be positioned as designed.

[0109] In this embodiment, the mounting fixture 1-1 has a third claw 36 that protrudes in the direction opposite to the protruding direction of the first claw 33, and a fourth claw 46 that protrudes in the direction opposite to the protruding direction of the second claw 43. As a result, when the first claw 33 and the second claw 43 are inserted into a foamed resin block 7-1, the third claw 36 and the fourth claw 46 can be inserted into 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 in the vertical and horizontal directions. This makes it possible to place the foamed resin block 7 for embankment in the designed position.

[0110] 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.

[0111] In this embodiment, the third claw portion 36 has a third anchor claw portion 38 that fits along the first anchor plate portion 32, and the fourth claw portion 46 has a fourth anchor claw portion 48 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 third anchor claw portion 38 and the fourth anchor claw portion 48 act as pressure-receiving surfaces, preventing the foam resin block 7 from being pulled out toward the front surface 71. This prevents the embankment panel 8 from falling off.

[0112] In this embodiment, the third claw portion 36 has a third connecting claw portion 37 that is aligned with the first connecting plate portion 31 and a third anchor claw portion 38 that is aligned with the first anchor plate portion 32, and the fourth claw portion 46 has a fourth connecting claw portion 47 that is aligned with the second connecting plate portion 41 and a fourth anchor claw portion 48 that is aligned with 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, thereby improving the strength of the claws. This prevents the claws from being damaged and makes them easier to insert into the foamed resin block 7.

[0113] (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 mounting 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 foamed resin block 7-1.

[0114] As shown in FIG. 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 blocks 7 are installed in the vertical and horizontal directions. This allows the embankment foam resin blocks 7 to be positioned as designed.

[0115] When embedding the third claw portion 36 and the fourth claw portion 46 in the intermediate floor slab 92, first, 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 7-1. At this time, the third claw portion 36 and the fourth claw portion 46 protrude from, for example, the upper 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 floor slab 92. This allows the third claw portion 36 and the fourth claw portion 46 to be embedded in the intermediate floor slab 92.

[0116] In this embodiment, the third claw portion 36 and the fourth claw portion 46 are embedded in the intermediate floor slab 92 adjacent to the foam resin block 7-1. This allows the foam resin block 7 and the intermediate floor slab 92 to be firmly connected, and prevents the foam resin block 7 from rocking due to an earthquake. This prevents the foam resin block 7 from shifting due to an earthquake.
