JP7704010B2 - SUPPORT STRUCTURE FOR SOLAR CELL MODULES AND SLOPE PROTECTION STRUCTURE WITH SOLAR CELL MODULES - Google Patents

Description

The present invention relates to a support structure for solar cell modules that is arranged to cover slopes such as natural slopes and embankments, and a slope protection structure with solar cell modules that uses the support structure for solar cell modules.

As renewable energy sources are gaining attention, there are an increasing number of cases where solar cell arrays are constructed on sloping ground or embankments to function as photovoltaic power generation systems. A solar cell array consists of solar cell modules and a solar cell stand that supports them, and the solar cell stand has a foundation that is installed underground.

For example, in Patent Document 1, block-shaped reinforced concrete is used for the foundation, with the lower part buried in the ground and the upper part protruding above the ground surface. Such foundations are often installed without considering the stability of the slope, which can easily cause the slope to become unstable, and there have been many cases of the slope collapsing along with the solar cell array during rainfall.

In this context, for example, Patent Document 2 discloses a method of using ground anchors in a support structure for solar cell modules to be installed on a slope. Specifically, a ground anchor is inserted into the ground, one end is fixed to stable ground while the other end protrudes above ground, and a pressure plate is placed on the slope so that the other end penetrates through. In this state, tension is introduced into the anchor material, and then a nut is screwed onto the anchor material and the pressure plate is installed on the slope, thereby providing a support structure on the slope. A frame-shaped connecting member is provided on the pressure plate of the support structure thus constructed, and the solar cell module is attached to this connecting member.

According to Patent Document 2, solar cell modules can be firmly installed on slopes using ground anchors. However, when the solar cell module is supported by a pressure plate, the weight of the solar cell module reduces the tension introduced into the anchor material. For this reason, it is necessary to estimate the load of supporting the solar cell module for the ground anchor to be adopted, which can make the design of the ground anchor complicated.

Furthermore, because ground anchors that introduce tension require timely inspection, a work space for inspection is provided in the vertical direction between the slope and the solar cell module. Providing a work space in the vertical direction creates an environment in which weeds can easily grow on the slope, making maintenance work such as weeding necessary. In addition, because the slope becomes susceptible to the effects of rainwater, it becomes necessary to take measures against the slope, such as installing separate slope protection works, to prevent surface collapse and slope erosion caused by seepage water due to rainfall.

In addition, wind that enters from the work space is likely to act upward from the back side of the solar cell module, which could cause the solar cell module to be damaged or scattered. For this reason, Patent Document 2 discloses a method in which the solar cell module is detachably attached to a connecting member provided on the pressure plate, thereby eliminating the need for a work space between the solar cell module and the slope, and allowing inspection of the ground anchor. However, the task of removing the solar cell module from the slope and lifting it up, and then reinstalling it after inspection every time inspection work is performed on the ground anchor can be cumbersome.

The present invention was developed in consideration of these problems, and its main objective is to easily install solar cell modules on slopes with a simple structure while ensuring the stability of slopes such as natural slopes and embankments.

To achieve this objective, the solar cell module support structure of the present invention is a solar cell module support structure in which a solar cell module is supported by a plurality of supports arranged in a planar shape with a space between them, the plurality of supports comprising a reinforcing material and a plate, one end of the reinforcing material protruding from the slope and the other end of the reinforcing material being inserted from the slope to a predetermined depth below the slide surface and fixed to the ground across the slide surface, the plate being fixed to the one end of the reinforcing material protruding from the ground while in contact with the slope, and the solar cell module being installed so as to connect the adjacent plurality of plates.

According to the support structure for the solar cell module of the present invention, the support comprises a reinforcing material and a plate, the reinforcing material prevents deformation and sliding of the ground, and the plate restrains the surface portion of the slope. In this way, the support serves both the function of stabilizing the slope and the function of serving as the foundation for the solar cell module. This allows an appropriate support to be designed for any slope depending on the condition of the slope on which the solar cell module is planned to be installed, making it possible to stably install the solar cell module without taking any additional measures against the slope. In addition, since a stand can be omitted when installing the solar cell module, the effects of seismic forces acting during an earthquake can be minimized, making it possible to avoid problems such as the collapse or damage of the solar cell module.

The support structure for the solar cell module of the present invention is characterized in that it includes a frame member that connects the adjacent plates while being grounded on the slope, and the solar cell module is installed on the frame member.

According to the solar cell module support structure of the present invention, the frame members are grounded to the slope in a manner that connects adjacent plates, so that they function like a slope frame on the slope. Then, when the solar cell modules are installed on these frame members, the load is transmitted to the surface portion via the frame members. This makes it possible to efficiently restrain the surface portion of the slope, and to suppress erosion and surface collapse (surface sliding) that tend to occur on the surface portion.

The solar cell module support structure of the present invention is characterized in that it includes a face plate that connects adjacent plates while being in contact with the slope, and the solar cell module is installed on the face plate.

According to the solar cell module support structure of the present invention, the face plates are grounded to the slope in a manner that connects adjacent plates, so that they function like a slope protection retaining wall on the slope. Therefore, it is possible to install solar cell modules on steep slopes or embankment slopes where there is a possibility of collapse of the surface layer or falling rocks, while also stabilizing these.

The support structure for the solar cell module of the present invention is characterized in that the solar cell module, the frame member, or the face plate are mounted on three adjacent plates.

The solar cell module support structure of the present invention provides support at three points, so even if the slope is not smooth and adjacent supports are uneven, the solar cell module, frame member, or face plate can be installed along the slope to cover it. This makes it difficult for wind to get into the gap between the slope and the solar cell module, reducing wind pressure acting in the direction of pulling out the solar cell module caused by typhoons and gusts of wind during bad weather.

The slope protection structure with solar cell modules of the present invention is characterized by comprising a support structure for the solar cell modules of the present invention and solar cell modules that are installed so as to connect adjacent multiple plates.

According to the slope protection structure with solar cell modules of the present invention, the solar cell modules are installed on multiple adjacent plates, so the load of the solar cell modules acts in a wide range on the surface of the slope, distributing it through the multiple plates. This makes it possible to stabilize the slope while installing the solar cell modules.

The slope protection structure with solar cell modules of the present invention is characterized in that a water-stopping layer or a drainage layer is provided on at least the area of the slope that is covered by the solar cell module.

The slope protection structure with solar cell modules of the present invention is characterized in that a drainage layer and a water-stopping layer covering the drainage layer are provided on at least the area of the slope that is covered by the solar cell module.

According to the slope protection structure with solar cell modules of the present invention, seepage water such as rainwater that has infiltrated into the ground can be quickly drained through the drainage layer. In addition, the water-stopping layer can prevent the seepage water from the ground from gushing out toward the solar cell module side, and can also prevent erosion and weathering of the slope caused by rainfall. In this way, the surface portion of the slope can be protected at all times, and instability of the surface portion can be prevented, so that damage to the solar cell module caused by soil and sand on the slope during bad weather, etc., will not occur.

Furthermore, the water-stopping layer also functions to eliminate factors that promote the growth of weeds, such as blocking sunlight. This eliminates the need for tasks such as weeding, making it possible to simplify the maintenance work of solar cell modules.

According to the present invention, the support that holds the solar cell module is composed of a reinforcing material that reinforces the ground and a plate that restrains the surface of the slope, and the solar panel is installed on this plate, so it is possible to easily install the solar cell module on a slope with a simple structure while ensuring the stability of the slope, such as a natural slope or a slope face.

The present invention involves inserting multiple reinforcing materials into slopes such as natural slopes and slope faces and using rock bolt construction to reinforce the natural ground and fix them to the ground, while using the multiple reinforcing materials fixed to the ground as supports to install solar cell modules so as to cover the slope.

Details of the support structure for solar cell modules and the slope protection structure with solar cell modules are explained below with reference to Figures 1 to 10, taking as an example the case where solar cell modules are installed on a slope. The slope may be any artificial slope, such as a cut slope or a fill slope. Furthermore, the support structure for solar cell modules and the slope protection structure with solar cell modules can be used on any slope, including natural slopes, not just slopes.

<<Slope protection structure with solar cell module>>
As shown in the front view of Fig. 1(a), a slope protection structure 100 with a solar cell module provided on a slope 201 includes a solar cell module 10 as shown in Fig. 1(b), a support structure for the solar cell module 10 as shown in Fig. 1(c), and a drainage layer 30 and a water stop layer 40 as shown in Fig. 2. The support structure for the solar cell module 10 is composed of a plurality of supports 20 arranged in a plane at intervals.

<<Solar cell module>>
As shown in Fig. 1(b), the solar cell module 10 is a power generation unit in which multiple solar cells 11 are enclosed in an envelope 12, and the envelope 12 is formed into a roughly right-angled triangle formed by dividing a square in half in a plan view. As a result, the solar cell module 10 has an outer shape that is roughly a right-angled triangle, and as shown in Fig. 1(a), it is supported at three points by adjacent supports 20 and is installed so as to cover a slope 201.

≪≪Support≫≫
1(a) and (c), a plurality of supports 20 are installed at intervals in the vertical and horizontal directions of the slope 201. The positions and intervals may be appropriately determined according to the condition of the natural ground 200. For example, they may be arranged in a staggered pattern, or the intervals may not be constant.

As shown in Figures 2(a) and 3(a), these supports 20 are installed integrally with the ground 200 and comprise a reinforcing member 21 that enhances the stability of the entire slope 201, and a pressure plate 22 that is fixed to one end of the reinforcing member 21 and restrains the surface portion of the slope 201. In addition to the pressure plate 22 and reinforcing member 21, a support plate 23, a fixing member 24, and a retaining member 25 are also provided.

The reinforcing material 21 is made of a long steel rod, and as shown in FIG. 2(a), one end of the reinforcing material 21 is inserted into an underground hole H that has been drilled to a predetermined depth deeper than the slide surface 202 of the soil mass, with one end protruding from the slope 201. The underground hole H is filled with grout G, and the reinforcing material 21 is fixed to the natural ground 200 via the grout G. In other words, the entire length of the reinforcing material 21, excluding the one end protruding from the slope 201, is fixed to the natural ground 200. Note that the reinforcing material 21 does not need to be fixed to the natural ground 200 near the slope 201, as long as the other end is inserted from the slope to a predetermined depth deeper than the slide surface 202 and is fixed to the natural ground 200 across at least the slide surface 202.

As shown in Fig. 3(a) and Fig. 4, the pressure plate 22 is a disk-shaped member through which the reinforcing material 21 fixed to the ground 200 penetrates, and is fixed to one end of the reinforcing material 21 while being grounded to the slope surface 201 via the drainage layer 30 and water-stopping layer 40 described below. Any fixing means may be used, but in this embodiment, a bearing plate 23 and a fixing device 24 are used.

The support plate 23 is placed on the upper surface of the pressure plate 22 with the reinforcing material 21 passing through it. The fixing device 24 has a nut that can be screwed into a threaded portion formed near one end of the reinforcing material 21. Therefore, first, the pressure plate 22 with the reinforcing material 21 inserted therethrough is grounded to the slope surface 201 via the drainage layer 30 and the water-stopping layer 40, and the support plate 23 with the reinforcing material 21 similarly inserted therethrough is placed on its upper surface.

In this state, the fixing device 24 is attached to one end of the reinforcing material 21 and screwed in. As a result, the pressure plate 22 is fastened and fixed to the reinforcing material 21 while being sandwiched between the fixing device 24, the support plate 23, and the slope surface 201. A holding member 25 used to hold the solar cell module 10 is installed on such a pressure plate 22.

As shown in Figures 3(a) and 4, multiple holding members 25 are installed on the upper surface of the pressure plate 22, and each holding member 25 comprises an attachment member 251 that is connected to the solar cell module 10, and a connecting portion 252 that is fixed to the pressure plate 22 and connected to the attachment member 251. These form a so-called ball joint, and the solar cell module 10 connected to the attachment member 251 is connected to the pressure plate 22 in a manner that allows the position to be freely changed.

<<Solar cell module support structure>>
A support structure for the solar cell module 10 is formed by constructing a plurality of these supports 20 so as to form a surface at intervals in the construction target area. Then, as shown in Fig. 4, for example, one solar cell module 10 is arranged and connected to the holding member 25 so as to connect the pressure receiving plates 22 of three adjacent supports 20. In this way, one solar cell module 10 is supported by the three supports 20 in a manner that covers the slope surface 201.

At this time, as shown in FIG. 4, the pressure plate 22 is provided with multiple holding members 25 in the radial direction, so that multiple solar cell modules 10 are connected to one pressure plate 22 via the holding members 25. In this way, as shown in FIG. 1(a), a slope protection structure 100 with solar cell modules is formed, in which multiple solar cell modules 10 are installed so as to cover the slope surface 201 without gaps over the entire construction area.

In addition, the reinforcing material 21 provided on the support 20 can prevent deformation and slippage of the ground 200. Furthermore, as shown in Figs. 2(a) and (b), the pressure plate 22 grounded on the slope 201 via the drainage layer 30 and the water-stopping layer 40 not only restrains the surface of the slope 201, but also distributes the load of the solar cell module 10 over a wide area of the surface via the multiple pressure plates 22. Therefore, by adopting the support 20, it is possible to install the solar cell module 10 on the slope 201 while increasing the stability of the entire slope 201.

In addition, since the solar cell stand that is generally used when installing the solar cell module 10 can be omitted, the solar cell module 10 and the slope 201 can be placed close to each other. Therefore, as shown in FIG. 3(b), when strong winds or gusts occur due to bad weather, these winds are less likely to enter the gap between the solar cell module 10 and the slope 201, and it is possible to suppress the phenomenon of wind pressure acting in the direction of pulling out the solar cell module 10 on the back side.

Furthermore, as shown in FIG. 3(b), during an earthquake, loads act alternately on the support 20 in the pull-out and push-in directions. However, since the load of the solar cell module 10 is applied to the pressure plate 22 via the holding member 25, it is possible for the load to resist the force in the pull-out direction together with the reinforcing material 21 fixed to the ground 200, and stably support the solar cell module 10. Note that if the slope 201 is steeply inclined, the load of the solar cell module 10 acts on the pressure plate 22 in the pull-out direction.

In this case, however, the reinforcing member 21 can be designed in advance taking into consideration the load of the solar cell module 10 that may act in the pull-out direction. The material of the reinforcing member 21 may be any of rod-shaped members that can be used in rock bolt construction to integrate the module with the ground 200, rock bolts, deformed rods, threaded rods, or other steel bars, or GFRP rock bolts.

The material of the pressure plate 22 may be any material, such as concrete, steel, or composite material. In addition, the planar shape is not limited to a disk shape, and may be a cross, semi-cross, or square shape that is commonly used in slope protection work. Furthermore, the fixing device 24 is not necessarily limited to a capped nut as shown in FIG. 3(a), as long as it has a nut that can be screwed into the threaded portion formed near one end of the reinforcing material 21.

The support bodies 20 may not necessarily be aligned vertically and horizontally as shown in FIG. 1(c). In such cases, it is a good idea to prepare solar cell modules 10 having various shapes in plan view, such as an isosceles triangle or an equilateral triangle, in advance. In this way, it is possible to appropriately combine various solar cell modules 10 having different planar shapes depending on the position of the support bodies 20.

On the other hand, for example, if the ground 200 is an embankment, the surface of the slope 201 is smooth and the supports 20 are hardly uneven. In this case, the solar cell module 10 does not necessarily have to be supported at three points by three supports 20. Therefore, the planar shape of the solar cell module 10 is not necessarily limited to a triangle, and it may be formed into a polygonal shape, such as a square or pentagon, that can cover the area of the slope 201 surrounded by adjacent supports 20, depending on the arrangement of the supports 20 constructed on the slope 201.

For example, Figure 5 shows an example in which a square solar cell module 10 is used. In this case, the corners of the solar cell module 10 are connected to the pressure receiving plates 22 via holding members 25, and the solar cell module 10 is installed so as to connect four adjacent pressure receiving plates 22. In other words, the solar cell module 10 is supported at four points by four adjacent supports 20, and the load can be distributed and applied over a wide area of the surface portion via the four pressure receiving plates 22.

<<Other examples of solar cell module support structures>>
<Example of adding frame components>
The support structure for the solar cell module 10, which is composed of a plurality of supports 20 arranged to form a surface with the above-mentioned spacing, may further adopt a frame member 61 and provide a support frame 60 in the support structure for the solar cell module 10, as shown in Figures 6(a) and (b), if the stability of the slope 201 is low and there is a risk of rockfall or collapse of the surface layer.

As shown in FIG. 6(a), the support frame 60 has multiple frame members 61 that are triangular in plan view, and these are connected via the pressure plate 22 of the support body 20, so that it functions like a slope frame on the slope 201. In other words, the support structure of the solar cell module 10 is a structure that includes a slope protection work that combines rock bolt work and open frame work, and protects the slope 201 more stably. When the solar cell module 10 is installed on the frame members 61 that constitute the support structure of such a solar cell module 10, as shown in FIG. 6(b), the load is transmitted to the surface part of the slope 201 through the support frame 60. Therefore, even if the surface part of the slope 201 is unstable, it is possible to efficiently restrain them and suppress erosion and surface collapse (surface sliding) that may occur in the surface part.

The frame member 61 that functions as described above is manufactured by assembling rod-shaped members into a triangle and fixing them by welding or the like, as shown in FIG. 7(a), and is formed by placing two angle steel pieces back to back, as shown in FIG. 7(b). Therefore, its cross section is an inverted T-shape with a rising portion 62 and a bottom portion 63. The bottom portion 63 of this inverted T-shape is positioned so that it comes into contact with the slope surface 201 via the drainage layer 30 and the water-stopping layer 40, as shown in FIG. 8.

In this state, the frame members 61 are arranged to link three adjacent pressure receiving plates 22 and connected to the holding members 25. As a result, one frame member 61 is supported by three supports 20. At this time, since the pressure receiving plate 22 is provided with multiple holding members 25 in the radial direction, multiple frame members 61 are connected to one pressure receiving plate 22 via the holding members 25. As a result, as shown in Figure 6 (a), a support structure for solar cell modules 10 comprising a support frame 60 consisting of multiple frame members 61 and pressure receiving plates 22 can be provided throughout the entire construction area.

As shown in FIG. 6(b), the solar cell module 10 is fitted and installed in the inner space surrounded by the rising portion 62 of the frame member 61, forming a slope protection structure 100 with a solar cell module. This makes it possible to fix small-scale collapses that may occur on the slope 201, as well as unstable masses of soil such as falling rocks.

The frame member 61 is not necessarily limited to being formed by placing two angle steel pieces back to back. As long as it has at least a bottom portion 63 and a configuration in which the solar cell module 10 can be placed, such as the rising portion 62, a precast member made of reinforced concrete may be used. Similarly to the planar shape of the solar cell module 10, the planar shape of the frame member 61 can be a variety of shapes, such as a right-angled triangle or an equilateral triangle, depending on the construction position and spacing of the support 20. It is also possible to form the support frame 60 by appropriately combining frame members 61 of different shapes.

<Example of adding surface materials>
In cases where sufficient stability cannot be ensured for the surface layer of the slope 201 by restraining it with the frame member 61, or in cases where the roll compaction of the constructed embankment is insufficient, a surface material 71 may be used instead of the frame member 61, and a support wall 70 may be provided in the support structure of the solar cell module 10, as shown in Figures 9(a) and (b).

As shown in FIG. 9(a), the support wall 70 has multiple face members 71, which are connected via the pressure plate 22 of the support body 20, and function like a slope protection retaining wall on the slope 201. Therefore, the support structure of the solar cell module 10 can stabilize the slope 201 even on slopes with an unstable surface, such as natural slopes where collapses and rockfalls are possible, or the slope 201 of embankments where compaction may be insufficient.

As shown in FIG. 10(a), the panel 71 that functions as described above is composed of the above-mentioned multiple frame members 61 and a panel body 72 that is arranged to block the internal space. Both the frame members 61 and the panel body 72 are grounded to the slope 201 via the drainage layer 30 and the water-stopping layer 40. In this state, a solar cell module 10 is installed on the panel body 72, forming a slope protection structure 100 with a solar cell module, as shown in FIG. 9(b).

However, the surface material 71 is not limited to this. For example, as shown in FIG. 10(b), a single flat plate material may be used as the surface material 71 and fixed integrally with the pressure receiving plate 22 constituting the support body 20 to form the support wall 70. In other words, any surface material 71 may be used as long as it has a lower surface that can be grounded to the slope surface 201 via the drainage layer 30 and the water stop layer 40, a solar cell module 10 can be placed on the upper surface, and its planar shape is formed to close the space surrounded by multiple adjacent pressure receiving plates 22.

As described above, in the slope protection structure 100 with solar cell modules, the support body 20 is equipped with a reinforcing material 21 and a pressure plate 22, the reinforcing material 21 prevents deformation and sliding of the ground 200, and the pressure plate 22 restrains the surface portion of the slope 201. In this way, the support body 20 functions both to stabilize the slope 201 and to serve as the foundation for the solar cell module 10.

As a result, it is possible to design an appropriate support 20 according to the condition of the slope in the construction area, not only for the slope 201 of cut or banked earth, but also for any slope such as a natural slope, so it is possible to easily install the solar cell module 10 on the slope with a simple configuration while ensuring the stability of the slope without taking any other measures against the slope.

The slope protection structure 100 with solar cell modules formed by supporting the solar cell modules 10 with the above-mentioned support structure has a drainage layer 30 and a water-stopping layer 40 provided at least on the slope surface 201 located below the solar cell modules 10.

<<Drainage layer and water-stopping layer>>
As shown in Fig. 2(a), the drainage layer 30 is laid on the upper surface of the slope 201 to actively collect seepage water 203 from the natural ground 200 and drain it to the slope toe drainage ditch 50. Any material may be used for the drainage layer 30, such as split chestnuts, drainage mats, or baskets, as long as it is made of a material that has drainage properties and can cover the slope 201. The drainage layer 30 may also be formed by combining a plurality of different types of drainage materials.

In addition, if the surface portion of the slope 201 is made of soil material with drainage function, such as a gravel layer 204, as shown in Figure 2 (b), and the seepage water 203 in the ground 200 can be guided to the slope toe drainage ditch 50 through this gravel layer 204, the drainage layer 30 may be omitted.

The water-stopping layer 40 is laid so as to cover the drainage layer 30 in FIG. 2(a) and the top surface of the gravel layer 204 in FIG. 2(b), and prevents the seepage water 203 flowing down these from gushing out toward the solar cell module 10. It also prevents rainwater from flowing into the ground 200 from the slope 201 through the gaps between adjacent solar cell modules 10 during rainfall. The material used for the water-stopping layer 40 may be any material capable of covering the drainage layer 30 and the gravel layer 204, such as a bentonite-based waterproof sheet or a high-density polyethylene sheet.

For example, as shown in FIG. 10(b), when adjacent pressure plates 22 and face material 71 are integrally formed and the entire surface of the drainage layer 30 is covered, the water-stopping layer 40 may be omitted.

In this way, by providing the drainage layer 30 and the water-stopping layer 40 at least on the slope 201 located below the solar cell module 10, the seepage water 203, such as rainwater, that has seeped into the ground 200 can be quickly drained through the drainage layer 30. The water-stopping layer 40 can prevent the seepage water 203 in the ground 200 from gushing out toward the solar cell module 10, and can also prevent erosion and weathering of the slope 201 due to rainfall.

In this way, the surface portion of the slope 201 can be protected at all times, and instability of the surface portion can be suppressed, so that damage to the solar cell module 10 due to soil and sand on the slope 201 being washed away during bad weather, etc., will not occur. Furthermore, the water-stopping layer 40 also has the function of eliminating factors that promote the growth of weeds, such as blocking sunlight. This makes it possible to omit the work of weeding the slope 201 located on the underside of the solar cell module 10, and simplifies the maintenance and management of the solar cell module 10.

The solar cell module support structure and the solar cell module-attached slope protection structure of the present invention are not limited to the above-described embodiments, and various modifications are possible without departing from the spirit of the present invention.

For example, in this embodiment, a case is given in which a new reinforcing material 21 is prepared and fixed to the ground 200, and then the support 20 is constructed, and this support 20 is used to provide the slope protection structure 100 with a solar cell module. However, this is not limited to this, and for example, the support 20 may be constructed using an existing rock bolt fixed to the ground 200 reinforced by rock bolt work as the reinforcing material 21.

In addition, a support 20 constructed using existing rock bolts and a new support 20 constructed using new reinforcing material 21 may be placed side by side on the slope, and used to support the solar cell module 10.

Furthermore, in this embodiment, the mounting member 251 of the holding member 25 is connected to the corner of the solar cell module 10. However, as long as the solar cell module 10 can be held and its load can be applied to the pressure plate 22, the mounting position is not limited to the corner of the solar cell module 10.

In addition, in this embodiment, the pressure plate 22 is used as an example of a plate fixed to one end of the reinforcing material 21 protruding from the ground 200, and a configuration in which the retaining member 25 is provided on the pressure plate 22 is illustrated, but this is not necessarily limited to this. For example, if the support plate 23 has an area large enough to accommodate the retaining member 25, the support plate 23 may be treated as a plate instead of the pressure plate 22, and the retaining member 25 may be provided on the support plate 23. In this case, the pressure plate 22 does not need to be provided on one end of the reinforcing material 21.
