Abstract
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 surfaces of the foam resin blocks. The connecting portions are approximately 3.2 mm thick, significantly thicker than the plate thickness (approximately 0.6 mm) of the fastening fittings installed to connect and fasten the foam resin blocks together. Therefore, when the foam resin blocks are arranged side by side, the connecting portions arranged along the upper or lower surfaces of one foam resin block interfere with the adjacent foam resin block. The position of the foam resin block shifts from its designed position only in the area where the connecting portions interfere. As the foam resin blocks are arranged, the positional shift of the foam resin blocks accumulates and becomes larger. This interference between the connecting portions poses a problem: the foam resin blocks cannot be positioned as designed. Furthermore, because the connecting portions have a large exposed area on the upper surface, adjusting the position of the foam resin blocks can cause the connecting portions to come into contact with each other, widening the gap and creating large voids that prevent the foam resin blocks from making surface contact with each other, potentially compromising the integrity of the embankment structure. For this reason, if the foam resin block is cut so that the connecting parts do not interfere with each other and the connecting parts are placed in the cut-out parts, the foam resin block needs to be cut again, which makes construction time-consuming and causes problems such as the disposal of the resulting shavings.In addition, because the foam resin block is cut, the reusability (recyclability) of the foam resin block is impaired.
[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 eliminates the need to cut foam resin blocks for embankments, enables the foam resin blocks to be placed in the designed position, and makes 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) As shown in FIGS. 1 and 2 , the embankment structure 100 is an embankment structure in which embankment panels 8 serving as covering members are attached to foam resin blocks 7 via 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 foam resin blocks 7, embankment panels 8, and fixtures 1. The embankment structure 100 may also include foam resin blocks 7, 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 fixtures 1 for attaching the joint plate 79 to the foam resin blocks 7.
[0013] A remaining formwork panel 95 is provided in front of the upper deck slab 91.
[0014] 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.
[0015] 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.
[0016] The embankment panel 8 is attached to the foam resin block 7 via the mounting fixture 1. The covering member is attached to the front surface 71 of the foam resin block 7 to protect the foam resin block 7. The covering member may be any panel material that can be used as a surface finishing material for civil engineering structures constructed by the lightweight embankment method, such as a concrete panel, a resin panel, or a metal panel. In addition to panel material, the covering member may also be a sheet material made of resin or the like. A plurality of mounting fixtures 1 are attached to one embankment panel 8, spaced apart in the vertical direction. The multiple mounting fixtures 1 may, for example, be of the same shape.
[0017] 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.
[0018] 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.
[0019] As shown in Figure 3, the fixture 1 comprises a mounting portion 2 and an insertion portion 3. The mounting portion 2 and insertion portion 3 of the 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 fixture 1 is kept to a thickness similar to that of the fastening hardware (t = approximately 0.6 mm) installed to connect and secure the foamed resin blocks 7 together, so the design does not affect the accuracy of stacking and construction of the foamed resin blocks 7.
[0020] 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.
[0021] 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.
[0022] 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.
[0023] 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.
[0024] 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.
[0025] 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.
[0026] The second restricting plate portions 53, 54 have folded pieces 53a, 54a formed by bending them in directions approaching each other.
[0027] 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.
[0028] A first pressure-receiving portion 39 is formed at the upper end of the first connecting plate portion 31 by bending it at a substantially right angle to the first connecting plate portion 31 toward the side opposite to the second connecting plate portion 41. The first pressure-receiving portion 39 extends in the horizontal direction. Note that in the present invention, the first pressure-receiving portion 39 may 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 blade plate portion 23 in a plan view.
[0030] A second pressure-receiving portion 49 is formed at the upper end of the second connecting plate portion 41 by bending the second connecting plate portion 41 at a substantially right angle toward the opposite side from the first connecting plate portion 31. Note that in the present invention, the second pressure-receiving portion 49 may 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 portion 49 extends to the position of the second receiving blade plate portion 24 in a plan view.
[0032] 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.
[0033] 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 makes it easy to insert the first claw portion 33 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 have at least one of a first connecting claw portion 34 that is along the first connecting plate portion 31 and a first anchor claw portion 35 that is 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. This makes it easy to insert 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 portion 33a, and an extension portion 352 that is connected to the inclined portion 351 and extends in 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.
[0034] A cutout portion 353 is formed by cutting out the extension portion 352. By providing the cutout portion 353, when the mounting fixture 1 is embedded in the foamed resin block 7, it is prevented from being pulled out of the foamed resin block 7.
[0035] 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 is inclined from the apex 43a. 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 an extension portion 452 that is connected to the inclined portion 451 and extends in 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.
[0036] A cutout portion 453 is formed by cutting out the extension portion 452. By providing the cutout portion 453, when the mounting fixture 1 is embedded in the foamed resin block 7, it is prevented from being pulled out of the foamed resin block 7.
[0037] 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.
[0038] 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.
[0039] 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.
[0040] 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.
[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, 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.
[0042] 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.
[0043] <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.
[0044] 4 to 6, in the insertion step, the mounting fixture 1-1 is inserted into the lower foamed resin block 7-1. To facilitate the insertion of the mounting fixture 1-1, it is preferable to make a cut in the foamed resin block 7-1 in advance using a cutter or the like.
[0045] 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.
[0046] 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.
[0047] 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.
[0048] 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.
[0049] 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. This prevents the mounting fixture 1-1 from interfering with other foam resin blocks 7 when the foam resin blocks 7 are installed vertically or horizontally. The mounting fixture 1-1 is designed to have high rigidity by incorporating the cross section of the insertion portion 3 and the resistance of the foam resin block 7 at the insertion portion 3 into its structure, allowing the areas of the first pressure-receiving portion 39 and the second pressure-receiving portion 49 to be kept small. Furthermore, the thickness of the insertion portion 3 is close to the thickness (approximately 0.6 mm) of the fastening hardware installed to join the foam resin blocks 7 together, so it does not affect the stacking accuracy of the foam resin blocks 7. This eliminates the need to cut the foamed resin blocks for embankment, and allows the foamed resin blocks 7 to be placed at the designed positions.
[0050] 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.
[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. By forming the first pressure-receiving portion 39, when the mounting fixture 1-1 is embedded in the foamed resin block 7-1, the first pressure-receiving portion 39 comes into contact with the upper surface 73 of the foamed resin block 7-1. In other words, the first pressure-receiving portion 39 can function as a stopper when the mounting fixture 1-1 is embedded in the foamed resin block 7-1. Therefore, even if a cut has been made in advance in the foamed resin block 7-1 with a cutter or the like to facilitate insertion of the mounting fixture 1-1, the mounting fixture 1-1 can be prevented from being embedded in the foamed resin block 7-1 more than necessary, making it easy to install the mounting fixture 1-1 at the desired position in 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. By forming the second pressure-receiving portion 49, when the mounting fixture 1-1 is embedded in the foamed resin block 7-1, the second pressure-receiving portion 49 comes into contact with the upper surface 73 of the foamed resin block 7-1. In other words, the second pressure-receiving portion 49 can function as a stopper when the mounting fixture 1-1 is embedded in the foamed resin block 7-1. Therefore, even if a cutter or the like has been used to make a notch in the foamed resin block 7-1 in advance to facilitate insertion of the mounting fixture 1-1, the mounting fixture 1-1 can be prevented from being embedded in the foamed resin block 7-1 more than necessary, making it easy to install the mounting fixture 1-1 at the desired position in the foamed resin block 7-1.
[0053] In a plan view, the front end of the first pressure receiving portion 39 extends to the position of the first blade plate portion 23. Therefore, when the mounting fixture 1-1 is embedded in the foamed resin block 7-1, the front end of the first pressure receiving portion 39 is aligned with the front surface 71 of the foamed resin block 7-1.
[0054] In a plan view, the front end of the second pressure receiving portion 49 extends to the position of the second blade plate portion 24. Therefore, when the mounting fixture 1-1 is embedded in the foamed resin block 7-1, the front end of the second pressure receiving portion 49 is positioned in line with the front surface 71 of the foamed resin block 7-1.
[0055] Furthermore, the first pressure-receiving portion 39 and the second pressure-receiving portion 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, the thickness is as thin as the fastening metal fittings (approximately 0.6 mm thick) that are installed in a certain amount to secure the foamed resin blocks 7 together, so it 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 21 of the mounting fixture 1-1 and the embankment panel 8-1 are attached using fasteners. In the installation process, the co-rotation suppression plate 5 is disposed between the first connecting plate 31 and the second connecting plate 41. Then, in the installation process, 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, 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. Therefore, co-rotation of the bolts 25 and nuts 26 provided on the co-rotation suppression plate 5 can be suppressed.
[0057] As shown in Fig. 7, the second restraining plate portions 53, 54 have folding pieces 53a, 54a formed by bending. As a result, even if the bolt 25 comes into contact with the embankment panel 8-1 and the co-rotation restraining plate portion 5 is pushed toward the foamed resin block 7-1 when the bolt 25 is inserted into the embankment panel 8-1 during the installation process, the folding pieces 53a, 54a serve as pressure-receiving surfaces and can 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 folding pieces 53a, 54a can function as stoppers, preventing the second restraining plate portions 53, 54 of the co-rotation restraining plate portion 5 from being embedded in the foamed resin block 7-1.
[0058] Next, as shown in FIG. 9, 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.
[0059] As shown in FIG. 10 , 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. This prevents the fixture 1-2 from interfering with other foamed resin blocks 7 when the foamed resin block 7 is installed vertically and horizontally. This allows the embankment foamed resin block 7 to be positioned as designed.
[0060] 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.
[0061] 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.
[0062] 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.
[0063] In this embodiment, the mounting fixture 1-1 has a first claw 33 that 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 a second claw 43 that 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. This allows the mounting fixture 1 to be embedded in the foamed resin block 7 when inserted into the foamed resin block 7. The first pressure-receiving portion 39 and the second pressure-receiving portion 49 are also very thin, with thicknesses of approximately 0.5 mm to 1 mm. Therefore, when the mounting fixture 1-1 is inserted into the foamed resin block 7-1, the thickness is as thin as the fastening hardware (approximately 0.6 mm thick) installed in a certain amount to secure the foamed resin blocks 7 together, so it does not affect the stacking accuracy of the foamed resin blocks 7. Therefore, when multiple foam resin blocks 7 are installed adjacent to each other in the vertical and horizontal directions, it is possible to prevent the fixture 1 inserted into one foam resin block 7 from interfering with another adjacent foam resin block 7. As a result, it is possible to eliminate the need to cut the foam resin blocks for embankment, and it is possible to place the foam resin blocks in the designed position.
[0064] 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.
[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, 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.
[0066] 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.
[0067] 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.
[0068] 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.
[0069] 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 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.
[0070] 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.
[0071] 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.
[0072] As shown in FIG. 11, 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.
[0073] 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.
[0074] 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.
[0075] In this embodiment, the first claw portion 33 has inclined portions 341, 351 that are inclined from the top portion 33a, and an extension portion 352 that extends from the inclined portion 351 in 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.
[0076] In this embodiment, the second claw 43 has inclined portions 441, 451 that are inclined from the top 43a, and an extension portion 452 that extends from the inclined portion 451 in the protruding direction of the second claw 43. This makes it even easier to insert the second claw 43 into the foamed resin block 7, making installation 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, when the mounting fixture 1 is embedded in the foamed resin block 7, the first pressure receiving portion 39 comes into contact with the upper surface 73 of the foamed resin block 7. In other words, the first pressure receiving portion 39 can function as a stopper when the mounting fixture 1 is embedded 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 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. By forming the second pressure receiving portion 49, when the mounting fixture 1 is embedded in the foamed resin block 7, the second pressure receiving portion 49 comes into contact with the upper surface 73 of the foamed resin block 7. In other words, the second pressure receiving portion 49 can function as a stopper when the mounting fixture 1 is embedded 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 in the foamed resin block 7.
[0079] In this embodiment, the second restraining plate portions 53, 54 have folding pieces 53a, 54a formed by bending. As a result, even if the bolt 25 comes into contact with the embankment panel 8-1 and the co-rotation restraining plate portion 5 is pushed toward the foamed resin block 7-1 when the bolt 25 is inserted into the embankment panel 8-1 during the installation process, the folding pieces 53a, 54a serve as pressure-receiving surfaces and can 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 folding pieces 53a, 54a can function as stoppers, thereby preventing the second restraining plate portions 53, 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 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, making maintenance difficult. 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.
[0081] 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.
[0082] 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.
[0083] 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.
[0084] 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.
[0085] 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.
[0086] 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 spaced apart from the foam resin block 7. This creates a space between the embankment panel 8 and the foam resin block 7. This creates an air layer (heat shielding layer) between the embankment panel 8 and the foam resin block 7, which can suppress the transfer of heat from the foam resin block 7 to the embankment panel 8. This makes it possible to suppress deformation of the embankment panel 8.
[0087] 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 (heat shielding layer) between the embankment panel 8 and the foamed resin block 7, improving fire resistance.
[0088] In this embodiment, the fixture 1 has an attachment 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 attachment portion 2 and inserted into the foam resin block 7. This allows the foam resin blocks 7 to be lined up in contact with each other without sandwiching joint material between them, allowing the foam resin blocks 7 to be installed in the designed position. Because the position of the lower layer can be visually observed through the gap between the embankment panel 8 and the foam resin block 7, it is easy to accurately align the surfaces of the foam resin blocks 7. Furthermore, because the periphery of the embankment panel 8 is free from obstacles such as joint material and can be directly touched during work, the foam resin block 7 with the embankment panel 8 attached is easy to carry, improving workability, reducing the burden on workers, and improving construction efficiency.
[0089] 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, the joints between the foam resin blocks are completely closed, resulting in low heat dissipation from the joints. This means that heat from the highly insulating foam resin blocks is transferred to the embankment panel. This raises concerns about thermal deformation of the embankment panel. In this embodiment, the mounting fixture 1 has a mounting portion 2 that is positioned on the outside of the foam resin block 7 and to which a joint plate 79 is attached, and an insertion portion 3 that is connected to the mounting portion 2 and inserted into the foam resin block 7. This eliminates the need for caulking the joints 75. This ensures heat dissipation from the joints 75 and prevents deformation of the embankment panel 8.
[0090] 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, a construction yard is required to attach the joint material to the panels. Furthermore, it takes time for the adhesive to dry, and the adhesive cannot be applied in the event of rain or other factors. Furthermore, the work yard must be used as a curing yard, occupying space until the adhesive dries. This results in a long construction time. In this regard, in this embodiment, the mounting fixture 1 has a mounting portion 2 that is positioned outside 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 around the periphery of the embankment panel 8 via adhesive. This simplifies construction.
[0091] 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.
[0092] (Second embodiment) Next, an example of the fixture 1 in the second embodiment will be described. Detailed description of the same configuration as in the first embodiment will be omitted below.
[0093] As shown in Figure 12, in the mounting device 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 approximately at a right angle to the first connecting plate portion 31 toward the second connecting plate portion 41 side.
[0094] A second pressure-receiving portion 49 is formed at the upper end of the second connecting plate portion 41 by bending the second connecting plate portion 41 at a substantially right angle toward the first connecting plate portion 31 side.
[0095] (Third embodiment) Next, an example of the fixture 1 in the third embodiment will be described.
[0096] As shown in FIG. 13 , mounting portions 27 are formed by bending the upper end of the side plate portion 21b of the mounting plate portion 21. One mounting portion 27 is formed integrally with the first pressure receiving portion 39 and is disposed so as to protrude further forward than the first receiving blade plate portion 23. The other mounting portion 27 is formed integrally with the second pressure receiving portion 49 and is disposed so as to protrude further forward than the second receiving blade plate portion 24. Therefore, when the mounting tool 1-1 is embedded in the foamed resin block 7-1, the mounting portion 27 is disposed so as to protrude from the front surface 71 of the foamed resin block 7-1. A hole 27a for installing a drill screw 77 is formed in the mounting portion 27. Note that, in the present invention, one mounting portion 27 and the first pressure receiving portion 39 may be configured as separate bodies. Note that, in the present invention, the other mounting portion 27 and the second pressure receiving portion 49 may be configured as separate bodies. In the present invention, the mounting portion 27 may be formed on the upper end of the main plate portion 21 a of the mounting plate portion 21 .
[0097] 14 and 15, a joint plate 78 is fixed to the mounting portion 27 with drill screws 77. The joint plate 78 has a flat plate portion 78a fixed to the mounting portion 27 with the drill screws 77, a front plate portion 78b formed by bending vertically downward from the front end portion of the flat plate portion 78a, and a rear plate portion 78c formed by bending vertically downward from the rear end portion of the flat plate portion 78a.
[0098] The flat plate portion 78a is arranged so as to cover the space between the embankment panel 8 and the foamed resin block 7. This makes it possible to prevent rainwater and the like from entering the space between the embankment panel 8 and the foamed resin block 7. The front plate portion 78b is inserted into the first cutout portion 28 and the second cutout portion 29. The rear plate portion 78c is arranged on the front side of the remaining formwork panel 95.
