Summary of the Invention

Problems to be Solved by the Invention

[0004] In the foamed resin block with a surface material for embankment described in Patent Document 1, the fastener includes a connecting portion positioned along the upper or lower surface of the foamed resin block. Since the thickness of the connecting portion is approximately 3.2 mm, it is significantly thicker than the plate thickness (approximately 0.6 mm) of the fastening fittings installed to connect and fix the foamed resin blocks together. Therefore, when foamed resin blocks are laid side by side, the connecting portion positioned along the upper or lower surface of one foamed resin block interferes with the adjacent foamed resin block. The position of the foamed resin block shifts from its designed position only in the area where the connecting portion interferes, and as more foamed resin blocks are laid, the displacement of the foamed resin blocks accumulates and becomes larger. Thus, there was a problem that the foamed resin blocks could not be placed in the designed position due to interference of the connecting portion. In addition, because a large area of ​​the connecting portion is exposed on the upper surface, the connecting portions may come into contact with each other when adjusting the position of the foamed resin blocks, creating larger gaps and resulting in large air voids where the foamed resin blocks do not make surface contact with each other, thus posing a risk of compromising the soundness of the embankment structure. Therefore, if the foamed resin block was shaved down to prevent interference between the connecting parts, and the connecting parts were then placed in the shaved areas, the work of shaving the foamed resin block became necessary, resulting in poor workability, longer construction time, and problems such as the disposal of the resulting shavings. In addition, because the foamed resin block was shaved down, its reusability (recyclability) was compromised.

[0005] Therefore, the present invention was devised in view of the above-mentioned problems, and its purpose is to provide a mounting device, an embankment structure, and a method for constructing an embankment structure that eliminate the need to cut foamed resin blocks for embankment, allow foamed resin blocks to be placed in the designed position, and facilitate construction.

MODE FOR CARRYING OUT THE INVENTION

[0011] Hereinafter, an example of a fixture, an embankment structure, and a method for constructing an embankment structure as an embodiment of the present invention will be described while referring to the drawings.

[0012] (First Embodiment) As shown in FIGS. 1 and 2, the embankment structure 100 is an embankment structure in which an embankment panel 8 as a covering member is attached to a foamed resin block 7 for embankment via a fixture 1. The embankment structure 100 is a lightweight embankment constructed on a mountain slope or the like, and an upper floor slab 91 such as a road is provided on the upper side. The upper floor slab 91 is a concrete floor slab, and reinforcing bars (not shown) and the like are provided inside. The embankment structure 100 includes a foamed resin block 7, an embankment panel 8, and a fixture 1. The embankment structure 100 may include a foamed resin block 7, an embankment panel 8, and a joint material 70 provided at the joint portion 75 between adjacent foamed resin blocks 7. The joint material 70 may include a joint plate 79 provided across a plurality of adjacent foamed resin blocks 7 in at least one of the vertical and horizontal directions, and a fixture 1 for attaching the joint plate 79 to the foamed resin block 7.

[0013] A remaining form panel 95 is provided on the front surface of the upper floor slab 91.

[0014] The material of the foamed resin block 7 can adopt a foam made of synthetic resin such as polystyrene, polyurethane, and polyvinyl chloride. The foamed resin block 7 is formed in a rectangular parallelepiped shape. The foamed resin block 7 is constructed, for example, by stacking a plurality of them in a staggered pattern with their positions shifted in the vertical and horizontal directions. The foamed resin block 7 has a weight of, for example, 12 kg to 30 kg per piece, is easy to carry, and is preferably adopted because it is excellent in workability for the construction work of lightweight embankment.

[0015] The foamed resin block 7 has a front surface 71 on the side to which the embankment panel 8 is attached, side surfaces 72 on the side ends in the horizontal direction of the front surface 71, an upper surface 73 on the upper end side in the vertical direction of the front surface 71, and a lower surface 74 on the lower end side in the vertical direction of the front surface 71.

[0016] The embankment panel 8 is attached to the foamed resin block 7 via the mounting fixture 1. The covering member is attached to the front side 71 of the foamed resin block 7 to protect it. The covering member can be any material that can be used as a surface finishing material for civil engineering structures constructed by the lightweight embankment method, and panel materials such as concrete panels, resin panels, and metal panels can be used. In addition to panel materials, the covering member may also be a sheet material made of resin or the like. Multiple mounting fixtures 1 are attached to one embankment panel 8, spaced apart in the vertical direction. Multiple mounting fixtures 1 may be, for example, of the same shape.

[0017] The embankment panel 8 is provided with a steel plate 81, for example, with a hat-shaped cross-section, which forms the outer surface of the embankment panel 8. Holes are formed in the steel plate 81, forming the holes of the embankment panel 8. Fasteners for fastening 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 is applied to the steel plate 81, so that, for example, when fastening a concrete embankment panel 8 to the mounting fixture 1, damage to the concrete portion of the embankment panel 8 can be suppressed.

[0018] The mounting bracket 1 is a fitting for attaching the embankment panel 8 to the foamed resin block 7. The mounting bracket 1 is inserted into either the top surface 73, bottom surface 74, or side surface 72 of the foamed resin block 7. For example, four mounting brackets 1 are provided on one embankment panel 8, spaced apart in the vertical and horizontal directions. The mounting brackets 1 allow the embankment panel 8 to be attached at a distance from the front surface 71 of the foamed resin block 7.

[0019] As shown in Figure 3, the mounting fixture 1 comprises a mounting portion 2 and an insertion portion 3. The mounting portion 2 and insertion portion 3 of the mounting fixture 1 are formed by bending a single steel plate with a thickness of approximately 0.5 mm to 1 mm. The thickness of the mounting portion 2 and insertion portion 3 of the mounting fixture 1 is kept to a thickness similar to that of the fastening fittings (t=0.6 mm) installed to connect and fix the foamed resin blocks 7 together, so the design does not affect the stacking accuracy of the foamed resin blocks 7.

[0020] The mounting portion 2 is for attaching 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, a bolt 25 and a nut 26 as fasteners, a first receiving vane plate portion 23 and a second receiving vane plate portion 24. The insertion portion 3 is connected to the mounting portion 2 and is inserted into the inside of the foamed resin block 7. The insertion portion 3 has a first connecting plate portion 31 and a second connecting plate portion 41, a first anchor plate portion 32 and a second anchor plate portion 42, and a first claw portion 33 and a second claw portion 43.

[0021] The mounting plate portion 21 is formed in a U-shape and has a main plate portion 21a that contacts the embankment panel 8, and a pair of side plate portions 21b that are bent from both ends of the main plate portion 21a. The main plate portion 21a has through holes 22 for providing bolts 25 as fasteners. The main plate portion 21a is attached to the embankment panel 8 by bolts 25 and nuts 26. The through holes 22 are elongated holes that extend along the protruding direction of the first claw portion 33. When the through holes 22 are elongated holes, the mounting position of the embankment panel 8 can be adjusted in the direction of extension of the elongated holes.

[0022] For example, bolts such as M8 and M10 can be used as bolts 25. The bolts 25 are passed through the embankment panel 8. The bolts 25 are spaced apart from the foamed resin block 7. The bolts 25 have a threaded portion 25a formed on the tip side 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 screwed onto the threaded portion 25a, the nut 26 is not screwed onto the flat portion 25b, so the bolt 25 can be configured to slide in the extending direction of the through hole 22 of the elongated hole. In addition, the entire shaft of the bolt 25 may be made up of threaded portion 25a. In this case, when the nut 26 is screwed onto the threaded portion 25a, the bolt 25 can be fixed without sliding relative to the mounting plate portion 21.

[0023] On the end face of one side plate portion 21b opposite to the protruding direction of the first claw portion 33, a first notch 28 is formed on the side of the main plate portion 21a of the mounting plate portion 21 that is closer to the first receiving vane plate portion 23. On the end face of the other side plate portion 21b opposite to the protruding direction of the second claw portion 43, a second notch 29 is formed on the side of the main plate portion 21a of the mounting plate portion 21 that is closer to the second receiving vane plate portion 24. The first notch 28 and the second notch 29 face each other.

[0024] A co-rotation prevention plate portion 5 is attached to the mounting plate portion 21. The co-rotation prevention plate portion 5 is formed, for example, by bending a single steel plate into a U-shape. The co-rotation prevention plate portion 5 is provided between a pair of side plate portions 21b and is provided so as to be able to contact 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 portion 5 that is in contact with at least one of the pair of side plate portions 21b. Therefore, co-rotation between the bolt 25 and the nut 26 provided on the co-rotation prevention plate portion 5 can be suppressed.

[0025] The rotation-preventing plate portion 5 has a first restraining plate portion 51 and a pair of second restraining plate portions 53 and 54. The first restraining plate portion 51 is provided in contact with the main plate portion 21a and has a through hole 52 formed therein through which a bolt 25, which serves as a fastener, is provided. The second restraining plate portions 53 and 54 are formed by bending from both ends of the first restraining plate portion 51 and are provided facing each other. At least one of the second restraining plate portions 53 and 54 is provided in contact with at least one of the pair of side plate portions 21b.

[0026] The second restraining plate portions 53 and 54 have folded portions 53a and 54a formed by bending them toward each other.

[0027] The first connecting plate portion 31 and the second connecting plate portion 41 are formed at both ends of the mounting plate portion 21 and are flush with each other and facing the side plate portion 21b of the mounting plate portion 21.

[0028] At the upper end of the first connecting plate portion 31, a first pressure-receiving portion 39 is formed by bending the first connecting plate portion 31 at approximately a right angle to the first connecting plate portion 31, toward the opposite side from the second connecting plate portion 41. The first pressure-receiving portion 39 extends in the horizontal direction. In this invention, the first pressure-receiving portion 39 may also be formed by bending at least one of the upper end of the first connecting plate portion 31 and the upper end of the first anchor plate portion 32.

[0029] The front end of the first pressure-receiving portion 39 extends to the position of the first receiving vane portion 23 in a plan view.

[0030] At the upper end of the second connecting plate portion 41, a second pressure-receiving portion 49 is formed by bending the second connecting plate portion 41 at approximately a right angle to the second connecting plate portion 41, toward the opposite side from the first connecting plate portion 31. In this invention, the second pressure-receiving portion 49 may also be formed by bending at least one of the upper end of the second connecting plate portion 41 and the upper end of the second anchor plate portion 42.

[0031] The front end of the second pressure-receiving section 49 extends to the position of the second receiving vane section 24 in a plan view.

[0032] The first anchor plate portion 32 is formed by bending the first connecting plate portion 31 from the end opposite to the end on the mounting plate portion 21 side. The second anchor plate portion 42 is formed by bending the second connecting plate portion 41 from the end opposite to the end on the mounting plate portion 21 side. The first anchor plate portion 32 and the second anchor plate portion 42 are provided parallel to the main plate portion 21a.

[0033] The first claw portion 33 protrudes such that the end face of the bent portion between the first connecting plate portion 31 and the first anchor plate portion 32 becomes the top portion 33a. This makes it easy to insert into the foamed resin block 7. The first claw portion 33 is formed in an L-shape when viewed from the direction of protrusion of the first claw portion 33, along the first connecting plate portion 31 and the first anchor plate portion 32. The first claw portion 33 may have at least one of the following: 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. The first connecting claw portion 34 has an inclined portion 341 that slopes from the top portion 33a. This makes it easy to insert the first connecting claw portion 34 into the foamed resin block 7. The first anchor claw portion 35 has an inclined portion 351 that slopes from the top portion 33a, and an extended portion 352 that connects to the inclined portion 351 and extends in the direction of protrusion of the first claw portion 33. This makes it easier to insert the first anchor claw portion 35 into the foamed resin block 7.

[0034] A notch 353 is formed in the extended portion 352. The presence of the notch 353 prevents the attachment 1 from being pulled out of the foamed resin block 7 when it is embedded in the foamed resin block 7.

[0035] The second claw portion 43 protrudes such that the end face of the bent portion between the second connecting plate portion 41 and the second anchor plate portion 42 becomes the top portion 43a. This makes it easy to insert into the foamed resin block 7. The second claw portion 43 protrudes along the protruding direction of the first claw portion 33. The second claw portion 43 is formed in an L-shape when viewed from the protruding direction of the second claw portion 43, along the second connecting plate portion 41 and the second anchor plate portion 42. The second claw portion 43 may have at least one of the following: 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. The second connecting claw portion 44 has an inclined portion 441 that slopes from the top portion 43a. This makes it easy 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 an extended portion 452 that connects to the inclined portion 451 and extends in the direction of protrusion of the second claw portion 43. This makes it easier to insert the second anchor claw portion 45 into the foamed resin block 7.

[0036] A notch 453 is formed in the extended portion 452. The presence of the notch 453 prevents the attachment 1 from being pulled out of the foamed resin block 7 when it is embedded in the foamed resin block 7.

[0037] The first vane plate portion 23 and the second vane 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 vane plate portion 23 rises substantially vertically from the end of one side plate portion 21b of the mounting plate portion 21 toward the opposite side of the other side plate portion 21b. The first vane plate portion 23 has a hole 23a formed therein. The second vane plate portion 24 rises substantially vertically from the end of the other side plate portion 21b of the mounting plate portion 21 toward the opposite side of the one side plate portion 21b. The second vane plate portion 24 has a hole 24a formed therein. The first vane plate portion 23 and the second vane 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 vane portion 23 and the second receiving vane portion 24 can be firmly fixed to the foamed resin block 7.

[0038] The ends of the first vane plate portion 23 and the second vane plate portion 24 are positioned to protrude more than the top 33a of the first claw portion 33 and the top 43a of the second claw portion 43 in the direction of protrusion of the first claw portion 33. This allows the first vane plate portion 23 and the second vane plate portion 24 to be positioned in contact with the front surface 71 of the foamed resin block 7 when the top 33a of the first claw portion 33 and the top 43a of the second claw portion 43 are in contact with the outer surface (e.g., top surface 73) of the foamed resin block 7. Therefore, when inserting the mounting fixture 1 into the foamed resin block 7, the first vane plate portion 23 and the second vane plate portion 24 can be inserted while they 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 ends of the first vane plate portion 23 and the end of the second vane plate portion 24 may be positioned so as to protrude more than the top 33a of the first claw portion 33 and the top 43a of the second claw portion 43 in the direction of protrusion of the first claw portion 33.

[0039] Furthermore, 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 which are in contact with each other. The joints 75 are formed, for example, by the side surfaces 72 of the foamed resin blocks 7 which are in contact with each other.

[0040] The jointing material 70 suppresses the deterioration of the foamed resin block 7 due to ultraviolet rays, etc. The jointing material 70 comprises a mounting fixture 1 and a joint plate 79. The mounting fixture 1 can be used to attach the joint plate 79 to the front side 71 of the foamed resin block 7.

[0041] 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, etc., with a thickness of approximately 0.5 mm to 4 mm. The joint plate 79 is formed by stretching along the joint portion 75 between the foamed resin blocks 7. The joint plate 79 is formed by bending both ends in the short direction 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. Also, when the ends in the short direction 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. In addition, a groove may be formed at the ends in the short direction of the joint plate 79 to fit into the mounting portion 2. In this case, when the joint plate 79 is attached to the mounting portion 2, the longitudinal movement of the joint plate 79 can be suppressed.

[0042] The first notch 28 and the second notch 29 are cut in a tapered shape, narrowing from the entrance side to the back side. This makes it easier to insert the joint plate 79 into the first notch 28 and the second notch 29.

[0043] <First Embodiment: Construction Method for 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 embankments. The construction method for the embankment structure 100 involves attaching embankment panels 8 to multiple foamed resin blocks 7 arranged in the vertical and horizontal directions. The construction method for the embankment structure 100 includes, for example, an insertion step, an attachment step, and a joint plate installation step.

[0044] As shown in Figures 4 to 6, in the insertion process, the mounting bracket 1-1 is inserted into the lower foamed resin block 7-1. To facilitate the insertion of the mounting bracket 1-1, it is preferable to make cuts in the foamed resin block 7-1 beforehand using a cutter or the like.

[0045] In detail, first, as shown in Figures 4(a) and 4(b), during the insertion process, the top 33a of the first claw portion 33 of the mounting fixture 1-1 and the top 43a of the second claw portion 43 of the mounting fixture 1-1 are placed in contact with the upper surface 73 of the foamed resin block 7. At this time, the first receiving vane portion 23 and the second receiving vane portion 24 are placed in contact with the front surface 71 of the foamed resin block 7.

[0046] Then, as shown in Figures 5 and 6, in the insertion process, 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 upper surface 73 of the foamed resin block 7-1 while the first receiving vane plate portion 23 and the second receiving vane plate portion 24 are brought into contact with the front surface 71 of the foamed resin block 7-1. As a result, the first connecting plate portion 31 and the second connecting plate portion 41, the first anchor plate portion 32 and the second anchor plate portion 42, and the first claw portion 33 and the second claw portion 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.

[0047] The first claw portion 33 protrudes such that the end face of the bent portion between the first connecting plate portion 31 and the first anchor plate portion 32 becomes the top portion 33a, thus facilitating insertion into the foamed resin block 7-1. Similarly, the second claw portion 43 protrudes such that the end face of the bent portion between the first connecting plate portion 31 and the first anchor plate portion 32 becomes the top portion 43a, thus facilitating insertion into the foamed resin block 7-1.

[0048] Furthermore, during the insertion process, the mounting fixture 1-1 is inserted while the first receiving vane portion 23 and the second receiving vane 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.

[0049] When the mounting bracket 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. This prevents the mounting bracket 1-1 from interfering with other foamed resin blocks 7 when the foamed resin blocks 7 are installed in the vertical and horizontal directions. The mounting bracket 1 has a highly rigid design that incorporates the cross-section of the insertion portion 3 and the resistance force of the foamed resin block 7 in the insertion portion 3 into its structure, making it possible to keep the area of ​​the first pressure receiving portion 39 and the second pressure receiving portion 49 small. In addition, the plate thickness of the insertion portion 3 is close to the plate thickness (approximately 0.6 mm) of the fastening fittings that are installed in a certain quantity to join the foamed resin blocks 7 together, so it does not affect the stacking accuracy of the foamed resin blocks 7. Therefore, the work of cutting the foamed resin blocks for the embankment can be eliminated, and the foamed resin blocks 7 can be placed in the designed position.

[0050] When the mounting bracket 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 notch portion 28 and the second notch portion 29 are located on the outside of the foamed resin block 7-1.

[0051] A first pressure-receiving portion 39 is formed at the upper end of the first connecting plate portion 31 by bending it toward the second connecting plate portion 41. The formation of the first pressure-receiving portion 39 ensures that when the mounting fixture 1-1 is embedded in the foamed resin block 7-1, the first pressure-receiving portion 39 contacts the upper surface 73 of the foamed resin block 7-1. In other words, the first pressure-receiving portion 39 functions as a stopper when embedding the mounting fixture 1-1 in the foamed resin block 7-1. Therefore, even if the foamed resin block 7-1 has been pre-cut with a cutter or the like to facilitate the insertion of the mounting fixture 1-1, the mounting fixture 1-1 is prevented from being embedded in the foamed resin block 7-1 more than necessary, making it easier to install the mounting fixture 1-1 in the desired position on the foamed resin block 7-1.

[0052] A second pressure-receiving portion 49 is formed at the upper end of the second connecting plate portion 41 by bending it toward the first connecting plate portion 31. The formation of the second pressure-receiving portion 49 ensures that when the mounting fixture 1-1 is embedded in the foamed resin block 7-1, the second pressure-receiving portion 49 contacts the upper surface 73 of the foamed resin block 7-1. In other words, the second pressure-receiving portion 49 functions as a stopper when embedding the mounting fixture 1-1 in the foamed resin block 7-1. Therefore, even if the foamed resin block 7-1 has been pre-cut with a cutter or the like to facilitate the insertion of the mounting fixture 1-1, the mounting fixture 1-1 is prevented from being embedded in the foamed resin block 7-1 more than necessary, making it easier to install the mounting fixture 1-1 in the desired position on the foamed resin block 7-1.

[0053] The front end of the first pressure-receiving section 39 extends to the position of the first vane plate section 23 in a plan view. Therefore, when the mounting fixture 1-1 is embedded in the foamed resin block 7-1, the front end of the first pressure-receiving section 39 is positioned to align with the front surface 71 of the foamed resin block 7-1.

[0054] The front end of the second pressure-receiving section 49 extends to the position of the second vane plate section 24 in a plan view. Therefore, when the mounting fixture 1-1 is embedded in the foamed resin block 7-1, the front end of the second pressure-receiving section 49 is positioned to align with the front surface 71 of the foamed resin block 7-1.

[0055] Furthermore, the first pressure-receiving section 39 and the second pressure-receiving section 49 are very thin, with a thickness of approximately 0.5 mm to 1 mm. Therefore, when the mounting fixture 1-1 is inserted into the foamed resin block 7-1, its thinness is comparable to that of the fastening fittings (with a plate thickness of approximately 0.6 mm) that are installed in certain quantities to secure the foamed resin blocks 7 together, and thus does not affect the stacking accuracy of the foamed resin blocks 7.

[0056] Next, as shown in Figures 7 and 8, in the installation process, the mounting plate portion 21 of the mounting fixture 1-1 and the embankment panel 8-1 are attached using fasteners. In the installation process, the anti-rotation plate portion 5 is positioned between the first connecting plate portion 31 and the second connecting plate portion 41. Then, in the installation process, the first anti-rotation plate portion 51 and the mounting plate portion 21 are attached to the embankment panel 8-1 with bolts 25 and nuts 26. The second anti-rotation plate portions 53 and 54 are provided in contact with a pair of side plate portions 21b, respectively. As a result, when the bolt 25 is screwed in, a reaction force is obtained from the anti-rotation plate portion 5 that is in contact with at least one of the pair of side plate portions 21b. Therefore, the rotation of the bolt 25 and nut 26 provided on the anti-rotation plate portion 5 can be suppressed.

[0057] As shown in Figure 7, the second restraint plate portions 53 and 54 have folded portions 53a and 54a formed by bending. This ensures that even if the bolt 25 comes into contact with the embankment panel 8-1 when the bolt 25 is inserted into the embankment panel 8-1 during the installation process, causing the co-rotation restraint plate portion 5 to be pushed towards the foamed resin block 7-1, the folded portions 53a and 54a act as pressure-receiving surfaces and can contact the front surface 71 of the foamed resin block 7-1. When the bolt 25 is inserted into the embankment panel 8-1 during the installation process, the folded portions 53a and 54a can function as stoppers, thereby preventing the second restraint plate portions 53 and 54 of the co-rotation restraint plate portion 5 from being embedded in the foamed resin block 7-1.

[0058] Next, as shown in Figure 9, in the joint plate installation process, the joint plate 79 is installed in the first notch 28 and the second notch 29 of the mounting fixture 1-1 inserted into the foamed resin block 7-1.

[0059] Then, as shown in Figure 10, in the insertion process, the mounting bracket 1-2 is inserted into the lower surface 74 of the upper foamed resin block 7-2, which is located above the foamed resin block 7-1. The insertion of the mounting bracket 1-2 into the lower surface 74 of the foamed resin block 7-2 is the same as the insertion of the mounting bracket 1-1 into the upper surface 73 of the lower foamed resin block 7-1, so a detailed explanation is omitted. When the mounting bracket 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. This prevents the mounting bracket 1-2 from interfering with other foamed resin blocks 7 when the foamed resin blocks 7 are installed in the vertical and horizontal directions. Therefore, it is possible to place the foamed resin blocks 7 for embankment in the designed position.

[0060] 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 lower surface 74 of the upper foamed resin block 7-2, using bolts 25 and nuts 26. The installation of the embankment panel 8-2 is the same as the installation of the embankment panel 8-1, so a detailed explanation is omitted.

[0061] Then, in the joint plate installation process, foamed resin block 7-2 is installed on top of foamed resin block 7-1. In the joint plate installation process, when installing foamed resin block 7-2 on top of foamed resin block 7-1, the joint plate 79 installed on the mounting fixture 1-1 is installed in the first notch 28 and second notch 29 of the mounting fixture 1-2 inserted into foamed resin block 7-2. As a result, the joint plate 79 is installed so as to straddle foamed resin blocks 7-1 and 7-2.

[0062] In this manner, the insertion process, the installation 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 joint plate 79 was installed after the embankment panel 8-2 was attached to the mounting fixture 1-2 inserted into the foamed resin block 7-2, but the embankment panel 8-2 may be attached after the joint plate 79 was installed to the mounting fixture 1-2 inserted into the foamed resin block 7-2.

[0063] In this embodiment, the mounting bracket 1-1 has a first claw portion 33 that 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 top portion 33a, and a second claw portion 43 that protrudes along the protruding direction of the first claw portion 33 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 top portion. As a result, when the mounting bracket 1 is inserted into the foamed resin block 7, the mounting bracket 1 is embedded in the foamed resin block 7. Furthermore, the first pressure receiving portion 39 and the second pressure receiving portion 49 are very thin, with a thickness of about 0.5 mm to 1 mm. Therefore, when the mounting bracket 1-1 is inserted into the foamed resin block 7-1, its thin plate thickness is about the same as that of the fastening fittings (plate thickness about 0.6 mm) that are installed in a certain quantity to fix the foamed resin blocks 7 together, and thus does not affect the stacking accuracy of the foamed resin blocks 7. Therefore, when multiple foamed resin blocks 7 are installed adjacent to each other in the vertical and horizontal directions, it is possible to suppress interference between the mounting fixture 1 inserted into one foamed resin block 7 and other adjacent foamed resin blocks 7. As a result, the work of cutting away the foamed resin blocks for embankment can be eliminated, and the foamed resin blocks can be placed in the designed position.

[0064] In this embodiment, the first claw portion 33 protrudes such that the end face of the bent portion between the first connecting plate portion 31 and the first anchor plate portion 32 becomes the top portion 33a, thus facilitating insertion into the foamed resin block 7-1. Similarly, the second claw portion 43 protrudes such that the end face of the bent portion between the first connecting plate portion 31 and the first anchor plate portion 32 becomes the top portion 43a, thus facilitating insertion into the foamed resin block 7-1. Therefore, construction can be easily carried out.

[0065] 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, since the first claw portion 33 and the second claw portion 43 have a bent shape such as an angle, the strength of the claw can be improved. For this reason, a relatively low true density (12 kg / m³) is used. 3 ~30kg / m 3 Not only foamed resin blocks of a certain degree, but also those with a relatively high true density (46 kg / m³) 3 ~70kg / m 3 Even with foamed resin blocks (buoyancy control blocks) of a certain degree, the claw breakage is suppressed and insertion becomes easier. Therefore, it is possible to safely attach buoyancy control blocks to walls, even those that were difficult to install with conventional mounting fixtures.

[0066] In this embodiment, the first connecting plate portion 31 has a first anchor plate portion 32 formed by bending from the end opposite to the mounting plate portion 21, and the second connecting plate portion 41 has a second anchor plate portion 42 formed by bending from the end opposite to the mounting plate portion 21. As a result, when the embankment panel 8 is attached to the mounting fixture 1, the first anchor plate portion 32 and the second anchor plate portion 42 act as pressure-receiving surfaces, preventing them from being pulled out towards the front surface 71 of the foamed resin block 7. Therefore, the embankment panel 8 can be prevented from falling off.

[0067] In this embodiment, the first claw portion 33 has a first anchor claw portion 35 that is aligned with the first anchor plate portion 32, and the second claw portion 43 has a second anchor claw portion 45 that is aligned with 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 towards the front surface 71 of the foamed resin block 7. Therefore, the detachment of the embankment panel 8 can be suppressed.

[0068] In this embodiment, the mounting plate portion 21 is provided with a first receiving vane plate portion 23 and a second receiving vane plate portion 24 rising from both ends of the mounting plate portion 21. This allows the mounting fixture 1 to be inserted into the foamed resin block 7 while the first receiving vane plate portion 23 and the second receiving vane plate portion 24 are in contact with the front surface 71 of the foamed resin block 7. As a result, the mounting fixture 1 can be easily inserted into the designed position, and installation can be easily performed.

[0069] Furthermore, as shown in Figure 11, 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 the axis of rotation, due to the weight of the embankment panel 8-1. In this embodiment, the mounting plate portion 21 is provided with a first receiving vane plate portion 23 and a second receiving vane plate portion 24 rising from both ends. As a result, the first receiving vane plate portion 23 and the second receiving vane plate portion 24, which are in contact with the front surface 71 of the foamed resin block 7, act as pressure receiving surfaces, suppressing the tendency to rotate in the direction of arrow R in the figure. Therefore, it is possible to further suppress the mounting fixture 1 from being pulled out towards the front surface 71 side of the foamed resin block 7.

[0070] In this embodiment, at least one of the ends of the first vane plate portion 23 and the second vane plate portion 24 is positioned to protrude more than the top 33a of the first claw portion 33 and the top 43a of the second claw portion 43 in the protruding direction of the first claw portion 33. As a result, when at least one of the top 33a of the first claw portion 33 and the top 43a of the second claw portion 43 contacts the outer surface (e.g., top surface 73) of the foamed resin block 7, at least one of the first vane plate portion 23 and the second vane plate portion 24 can be provided in contact with the front surface 71 of the foamed resin block 7. Therefore, when inserting the mounting fixture 1 into the foamed resin block 7, the first vane plate portion 23 and the second claw portion 43 can be inserted with the first vane plate portion 23 and the second vane plate portion 24 in contact with the front surface 71 of the foamed resin block 7. As a result, it is easy to insert the mounting fixture 1 into the designed position of the foamed resin block 7.

[0071] In this embodiment, the through-hole 22 is an elongated hole. This allows the embankment panel 8 to be adjusted and installed at the desired position on site. Therefore, it is possible to improve the workability of the embankment panel 8.

[0072] Furthermore, as shown in Figure 11, in the embankment structure 100, the embankment panel 8-1 is attached by mounting fixtures 1-1 and 1-3. The fastener of the upper mounting fixture 1-1 consists of a bolt 25 with only a threaded portion 25a on the shaft. 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 consists of a bolt 25 with a threaded portion 25a and a flat portion 25b on the shaft. In this case, the fastener of mounting fixture 1-3 is configured to slide along the extension direction of the through hole 22, which is an elongated hole.

[0073] In this configuration, the foamed resin block 7 undergoes compressive deformation due to the added load, raising concerns about deformation of the embankment panel 8 due to the compressive deformation of the foamed resin block 7. In this embodiment, of the mounting fixtures 1-1 and 1-3 spaced vertically apart 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, while the fastener of mounting fixture 1-3 is configured to slide along the elongated through hole 22. This suppresses deformation of the embankment panel 8-1 due to the compressive deformation of the foamed resin block 7. As a result, damage to the embankment panel 8-1 can be suppressed.

[0074] In this invention, when the fastener of mounting fixture 1-1 is configured to slide, the fastener of mounting fixture 1-3 may be fixed so as not to slide. In this invention, the fasteners of mounting fixture 1-1 and mounting fixture 1-3 may each be fixed so as not to slide.

[0075] In this embodiment, the first claw portion 33 has inclined portions 341 and 351 that are inclined from the top portion 33a, and an extended portion 352 that extends from the inclined portion 351 in the direction of protrusion of the first claw portion 33. This makes it easier to insert the first claw portion 33 into the foamed resin block 7. As a result, construction can be made even easier.

[0076] In this embodiment, the second claw portion 43 has inclined portions 441 and 451 that are inclined from the top portion 43a, and an extended portion 452 that extends from the inclined portion 451 in the direction of projection of the second claw portion 43. This makes it easier to insert the second claw portion 43 into the foamed resin block 7. As a result, construction can be made even easier.

[0077] In this embodiment, a first pressure-receiving portion 39 is formed at the upper end of the first connecting plate portion 31 by bending it toward the second connecting plate portion 41. By forming the first pressure-receiving portion 39 at the upper end of the first connecting plate portion 31, the first pressure-receiving portion 39 comes into contact with the upper surface 73 of the foamed resin block 7 when the mounting fixture 1 is embedded in the foamed resin block 7. In other words, the first pressure-receiving portion 39 can function as a stopper when embedding the mounting fixture 1 in the foamed resin block 7. Therefore, it is possible to prevent the mounting fixture 1 from being embedded in the foamed resin block 7 more than necessary, and it becomes easier to install the mounting fixture 1 at the desired position in the foamed resin block 7.

[0078] In this embodiment, a second pressure-receiving portion 49 is formed at the upper end of the second connecting plate portion 41 by bending it toward the first connecting plate portion 31. The formation of the second pressure-receiving portion 49 ensures that when the mounting fixture 1 is embedded in the foamed resin block 7, the second pressure-receiving portion 49 contacts the upper surface 73 of the foamed resin block 7. In other words, the second pressure-receiving portion 49 functions as a stopper when embedding the mounting fixture 1 in the foamed resin block 7. This prevents the mounting fixture 1 from being embedded in the foamed resin block 7 more than necessary, making it easier to install the mounting fixture 1 in the desired position on the foamed resin block 7.

[0079] In this embodiment, the second restraining plate portions 53 and 54 have folded portions 53a and 54a formed by bending. As a result, even if the bolt 25 comes into contact with the embankment panel 8-1 when the bolt 25 is inserted into the embankment panel 8-1 during the installation process, causing the co-rotation restraining plate portion 5 to be pushed towards the foamed resin block 7-1, the folded portions 53a and 54a can act as pressure-receiving surfaces and come into contact with the front surface 71 of the foamed resin block 7-1. When the bolt 25 is inserted into the embankment panel 8-1 during the installation process, the folded portions 53a and 54a can function as stoppers, thereby preventing the second restraining plate portions 53 and 54 of the co-rotation restraining plate portion 5 from being embedded in the foamed resin block 7-1.

[0080] Conventionally, screws have been used to fix the embankment panels 8, but it was difficult to control the mounting strength of the embankment panels 8 with screws. In addition, screws cannot be attached or detached, making maintenance difficult. In this embodiment, however, a bolt 25 is provided as a fastener that penetrates the embankment panel 8. This allows the mounting strength of the bolt 25 to be controlled by torque. As a result, it is possible to improve the safety of the embankment structure.

[0081] In this embodiment, the embankment panel 8 has bolts 25 that penetrate it. This allows the bolts 25 to be attached and detached. Therefore, maintenance of the embankment structure 100 can be easily performed.

[0082] Furthermore, this embodiment includes bolts 25 that penetrate the embankment panel 8. This allows for fine adjustment of the mounting position of the embankment panel 8 even after it has been installed.

[0083] In this embodiment, the mounting bracket 1 is formed by bending a single sheet of metal. This allows for setting the thickness and material of the metal sheet. For example, in the case of a buoyancy control block where the foamed resin block 7 is mainly used below the groundwater level, corrosion of the metal sheet can be suppressed by using a stainless steel sheet.

[0084] In this embodiment, the anti-rotation plate portion 5 is provided between a pair of side plate portions 21b and is provided so as to be able to contact 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 anti-rotation plate portion 5 that is in contact with at least one of the pair of side plate portions 21b. Therefore, it is possible to suppress the co-rotation of the bolt 25 and the nut 26 provided on the anti-rotation plate portion 5.

[0085] In conventional embankment structures, the embankment panels are installed in contact with the front surface of the foamed resin blocks. As a result, rainwater is drained along the front side of the embankment panels. This tends to cause deterioration and soiling of the surface of the embankment panels due to rainwater, impairing the aesthetic appeal. In this embodiment, however, the mounting fixture 1 attaches the embankment panels 8 at a position spaced apart from the foamed resin blocks 7. This creates a space between the embankment panels 8 and the foamed resin blocks 7. As a result, rainwater is drained between the embankment panels 8 and the foamed resin blocks 7. Consequently, deterioration and soiling of the surface of the embankment panels 8 due to rainwater can be suppressed, and the aesthetic appeal can be maintained.

[0086] In conventional embankment structures, the embankment panels are installed in contact with the front of the foamed resin blocks. Therefore, when the temperature is high, heat from the highly insulating foamed resin blocks is transferred to the embankment panels. This raises concerns about thermal deformation of the embankment panels. In this embodiment, however, the mounting fixture 1 attaches the embankment panels 8 at a position spaced apart from the foamed resin blocks 7. This creates a space between the embankment panels 8 and the foamed resin blocks 7. As a result, the space between the embankment panels 8 and the foamed resin blocks 7 acts as an air layer (heat shielding layer), suppressing heat transfer from the foamed resin blocks 7 to the embankment panels 8. Consequently, deformation of the embankment panels 8 can be suppressed.

[0087] Furthermore, in this embodiment, the mounting fixture 1 is attached to the embankment panel 8 at a position spaced apart from the foamed resin block 7. This creates a space between the embankment panel 8 and the foamed resin block 7. As a result, the space between the embankment panel 8 and the foamed resin block 7 acts as an air layer (heat shielding layer), improving fire resistance.

[0088] In this embodiment, the mounting fixture 1 has a mounting part 2 that is positioned on the outside of the foamed resin block 7 and to which a joint plate 79 is attached, and an insertion part 3 that is connected to the mounting part 2 and inserted into the inside of the foamed resin block 7. This allows the foamed resin blocks 7 to be placed side by side in contact with each other without having joint material sandwiched between them, and the foamed resin blocks 7 to be installed in the designed position. Since the position of the lower section can be visually viewed from the gap between the embankment panel 8 and the foamed resin block 7, it becomes easy to accurately align the surface positions of the foamed resin blocks 7. In addition, since there are no obstacles such as joint material attached to the outer circumference of the embankment panel 8 and it can be directly touched by hand during work, the foamed resin block 7 with the embankment panel 8 attached is easy to carry, improving work efficiency, reducing the burden on workers, and improving constructability.

[0089] In conventional embankment structures, the joints between foamed resin blocks are sometimes sealed with caulk to suppress deterioration due to ultraviolet rays, etc. In this case, there are no gaps at all in the joints between the foamed resin blocks, resulting in low heat dissipation from the joints. As a result, heat from the highly insulating foamed resin blocks is transferred to the embankment panels. Therefore, there is a concern that the embankment panels may deform due to heat. In this embodiment, the mounting fixture 1 has a mounting part 2 that is positioned on the outside of the foamed resin block 7 and to which a joint plate 79 is attached, and an insertion part 3 that is connected to the mounting part 2 and inserted into the foamed resin block 7. This eliminates the need for caulking in the joints 75. Therefore, heat dissipation from the joints 75 can be ensured, and deformation of the embankment panels 8 can be suppressed.

[0090] In conventional embankment structures, to suppress deterioration due to ultraviolet rays, etc., resin cushioning material is sometimes bonded to the outer perimeter of each embankment panel with adhesive, and the joints of the foamed resin blocks are covered by bringing the cushioning materials of adjacent embankment panels into contact with each other. In this case, a construction yard is required to attach the joint material to the panels. In addition, it takes time for the adhesive to dry, and the application of this adhesive cannot be done in the event of rain, etc. Furthermore, the work yard must be used as a curing yard and taken up space until the adhesive dries. As a result, construction takes time. In this embodiment, the mounting fixture 1 has a mounting part 2 which is positioned on the outside of the foamed resin block 7 and to which the joint plate 79 is attached, and an insertion part 3 which is connected to the mounting part 2 and inserted into the foamed resin block 7. As a result, it is not necessary to install cushioning material on the outer perimeter of the embankment panel 8 via adhesive. Therefore, construction can be easily carried out.

[0091] In this embodiment, the joint plate 79 is attached to the first notch 28 and the second notch 29 of the mounting fixture 1-1 provided on the foamed resin block 7-1, which are opposite to each other. This allows the joint plate 79 to be inserted into the first notch 28 and the second notch 29. Therefore, the installation of the joint plate 79 is made easier.

[0092] (Second Embodiment) Next, an example of the mounting fixture 1 in the second embodiment will be described. Detailed explanations of configurations similar to those in the first embodiment will be omitted below.

[0093] As shown in Figure 12, in the mounting fixture 1 of the second embodiment, a first pressure receiving portion 39 is formed at the upper end of the first connecting plate portion 31, by bending it at approximately a right angle to the first connecting plate portion 31 toward the second connecting plate portion 41.

[0094] At the upper end of the second connecting plate portion 41, a second pressure receiving portion 49 is formed by bending it toward the first connecting plate portion 31 at approximately a right angle to the second connecting plate portion 41.

[0095] (Third embodiment) Next, an example of the mounting fixture 1 in the third embodiment will be described.

[0096] As shown in Figure 13, a mounting portion 27 is formed by bending at the upper end of the side plate portion 21b of the mounting plate portion 21. One mounting portion 27 is integrally formed with the first pressure receiving portion 39 and is positioned to protrude forward from the first receiving vane plate portion 23. The other mounting portion 27 is integrally formed with the second pressure receiving portion 49 and is positioned to protrude forward from the second receiving vane plate portion 24. Therefore, when the mounting fixture 1-1 is embedded in the foamed resin block 7-1, the mounting portions 27 are positioned to protrude from the front surface 71 of the foamed resin block 7-1. A hole 27a for installing a self-drilling screw 77 is formed in the mounting portion 27. In this invention, one mounting portion 27 and the first pressure receiving portion 39 may be configured as separate parts. In this invention, the other mounting portion 27 and the second pressure receiving portion 49 may be configured as separate parts. In this invention, the mounting portion 27 may be formed at the upper end of the main plate portion 21a of the mounting plate portion 21.

[0097] As shown in Figures 14 and 15, the joint plate 78 is fixed to the mounting portion 27 by self-drilling screws 77.
