Description

  The present invention relates to a curing mat and a curing material installed on the surface of an object to be protected such as a solar cell module.

  It is known that a solar cell module is installed on the roof of a building to supplement the power used in the building or sell the generated power to an electric power company.

  The surface of the solar cell module is covered with a transparent glass plate, so that the glass plate is not damaged or the power generation efficiency is not deteriorated by fouling the surface. Done.

  Patent Document 1 discloses a configuration in which a rope ladder-like scaffold is suspended from the end of a solar cell module arranged on the entire surface of the roof. The footboard of the scaffold has a structure in which an aluminum alloy footboard body is covered with a soft covering material so as not to damage the glass plate.

  On the other hand, in Patent Document 2, a lightweight scaffolding board having a layered structure made of a plastic board material is installed on the ceiling so that the desk or chair installed in the room of the building is not damaged. And performing piping work.

  Furthermore, Patent Document 3 discloses a configuration in which a glass-based plate is formed by applying a paint mainly composed of a urethane-based synthetic resin and cinnabar sand to the glass surface to make it difficult to slip.

  However, when solar cell modules are installed in a wide area of the roof, it is not sufficient to perform wiring work between solar cell modules and the like by simply providing a scaffold at the end as disclosed in Patent Document 1. I can not say.

  Moreover, since a curing material will be removed after completion | finish of work, it is desired that it is lightweight and easy to handle. For example, in a configuration in which a stainless steel plate as disclosed in Patent Document 4 is used as a core, it is difficult to handle at a high place due to its weight, and the area per piece and the number of pieces that can be connected are limited. Is done.

  Furthermore, even if it is installed on the surface of a slippery protection object such as a glass plate, it is necessary to use a curing material that does not slip so that the worker can walk with peace of mind.

  Therefore, an object of the present invention is to provide a curing mat and a curing material that are less likely to slip even if installed on a smooth surface such as glass, are light and easy to handle.

  In order to achieve the above object, the curing mat of the present invention is a curing mat installed on the surface of an object to be protected, and includes a flat core material having a gap inside and a bag for storing the core material. And a non-slip portion formed on the protection object side of the bag.

  Here, the core material may have a hollow structure. Moreover, the said core material can be set as the structure formed with a synthetic resin material. Furthermore, the said anti-slip | skid part can be set as the structure formed of the anti-slip | slipping material stuck at intervals.

  Moreover, it can be set as the structure by which the fastening part for inserting a wire is provided in the outer surface side of the said bag body. And the said protection target object can be made into a solar cell module.

  The curing material of the present invention is characterized in that a plurality of the curing mats are connected and can be folded at the connecting portion.

  In the curing mat of the present invention configured as described above, a non-slip portion is formed in a bag body that accommodates a core material having a gap inside. Further, the core material and the anti-slip portion are integrated with each other through the bag body.

  For this reason, even if it installs on smooth surfaces, such as glass, it is hard to produce slip. Moreover, since the core material which has a space | gap inside is used, it can reduce in weight, and since it is formed in the mat shape by the bag body, handling is easy.

  Furthermore, if the core material having a hollow structure is formed of a synthetic resin material, a material that satisfies the weight and strength standards can be easily formed. Moreover, weight reduction can be achieved by forming an anti-slip | skid part with the anti-slip | slipping material stuck at intervals.

  Moreover, by providing the fastening part which can insert a wire in the outer surface of a bag body, a curing mat can be moored and scattering by a wind can be prevented.

  Such a curing mat can be easily installed and removed on the solar cell module, and can prevent damage and contamination of the solar cell module covered with the curing mat.

  Moreover, since the curing material of this invention has connected the some curing mat so that it can fold in a connection part, it can be folded and put together in the magnitude | size which is easy to handle at the time of installation or removal.

It is the top view which showed the structure by the side of the surface of the curing material which connected multiple curing mats. It is the bottom view which showed the structure by the side of the back surface of the curing material which connected multiple curing mats. It is explanatory drawing which showed the process of attaching a curing material to the roof panel in which the solar cell module was assembled | attached. It is the figure which showed the process of fixing a curing material to a roof panel, Comprising: (a) is explanatory drawing which showed the process of fixing a curing mat to a solar cell module, (b) is the process of fixing the folded curing mat It is explanatory drawing which showed. It is sectional drawing seen in the AA arrow direction of FIG.5 (b). It is explanatory drawing which showed the process of opening the curing mat folded at the installation site.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view showing the configuration of the curing mat 11 of the present embodiment, and FIGS. 2 and 3 are a plan view and a bottom view showing the configuration of the curing material 1 of the present embodiment.

  The curing mat 11 or the curing material 1 of the present embodiment is installed on the surface of a solar cell module 6 (see FIG. 4) as an object to be protected. Here, the solar cell module 6 is a device that generates power by directly converting sunlight as solar energy into electric power by a solar cell.

  This solar cell module 6 is mainly comprised by the solar cell, the glass plate which covers the upper surface, and the flame | frame attached to those peripheral parts. A solar cell may be composed of any solar cell element such as a silicon crystal system (single crystal silicon, polycrystalline silicon), an amorphous system (amorphous silicon), a compound system (CIS, CdTe, GaAs, etc.) or an organic system. Good.

  Since the solar cell module 6 is often spread on the roof of a building, it is unavoidable that the solar cell module 6 is placed on the roof when performing installation work or maintenance work. Therefore, the curing mat 11 or the curing material 1 of the present embodiment is installed on the solar cell module 6 to perform the work.

  As shown in FIG. 1, the curing mat 11 includes a flat core material 2, a bag body 3 in which the core material 2 is accommodated, and an anti-slip material as an anti-slip portion attached to the back surface 3 b of the bag body 3. 4 is mainly composed.

  The core material 2 functions to prevent the concentrated load from acting on the solar cell module 6 by dispersing the upper load such as the weight of the operator. Moreover, the core material 2 is reduced in weight by setting it as the structure which has a space | gap inside.

  For such a core material 2, for example, a synthetic resin material having a hollow structure formed in a rectangular shape can be used. The hollow synthetic resin material includes plastic corrugated cardboard (commonly called “pradan”) such as polypropylene (PP), polyethylene (PE), and polycarbonate (PC).

  The bag body 3 is formed of a sheet material having water shielding properties. For example, it can be produced in a bag shape using a sheet material made of synthetic resin such as polyethylene. Specifically, as shown in FIG. 1, the sheet material is disposed above and below the core material 2, and the edge 31 is joined by sewing or welding to form the bag body 3.

  As for this bag body 3, the outer surface used as the solar cell module 6 side turns into the back surface 3b, and the outer surface on the side where an operator walks turns into the surface 3a. And the anti-slip | skid material 4 is affixed on the back surface 3b.

  For the anti-slip material 4, for example, a synthetic rubber sheet formed into a strip shape or a rectangle shape can be used. As the synthetic rubber, a downstream solid rubber such as ethylene-propylene rubber (EPR, EPDM) can be used.

  A plurality of such curing mats 11 are connected to the curing material 1 shown in FIGS. In the curing material 1 of the present embodiment, three curing mats 11, 11, and 11 are connected.

  The connection part 12 between the curing mats 11 and 11 is formed so as to be bent by folding the connection part 12. For example, it can be formed by abutting the edges 31, 31 of the curing mats 11, 11, and connecting the abutting locations with a tape. Further, the edges 31 and 31 may be overlapped and connected by sewing or welding.

  Further, as shown in FIG. 2, warning display portions 32 are provided on both ends of the curing mat 11 such as both sides of the connecting portion 12 to indicate to the operator “impossible to walk” or the like.

  This warning display part 32 can be formed by painting the surface 3a of the bag body 3 in yellow or red, or covering the sheet 3 with a color different from the color of the surface 3a. As will be described later, the curing mat 11 of the present embodiment is formed in a rectangular shape having substantially the same size as the solar cell module 6, and both ends of the curing mat 11 coincide with both ends of the solar cell module 6.

  Since it is better not to apply a large load to the end portion of the solar cell module 6, such a warning display portion 32 is provided. For this reason, the position of the warning display part 32 in the curing mat 11 changes depending on the relationship between the size of the curing mat 11 and the size of the solar cell module 6.

  Furthermore, the fastening part 5A for inserting a wire is provided in the vicinity of both ends of the surface 3a of the bag 3. The fastening portion 5A can be provided by joining both ends of a strip-shaped material made of a synthetic resin such as a polypropylene PP band to the surface 3a or the warning display portion 32 by sewing or welding.

  The holes of the fastening portion 5A provided in this way penetrate in the transverse direction of the curing mat 11 (direction perpendicular to the longitudinal direction of the curing material 1). For example, a wire rod for fixing the curing mat 11 can be passed by providing two fastening portions 5A and 5A at an end portion of the curing mat 11 with an interval in the transverse direction.

  On the other hand, FIG. 3 shows a back surface 3b of the curing material 1 in which three curing mats 11, 11, 11 are connected. On the back surface 3b, strip-shaped anti-slip materials 4,... Are attached at intervals in the longitudinal direction of the curing material 1.

  Specifically, two strip-shaped antiskid materials 4, 4 are attached to one curing mat 11 with the longitudinal direction thereof being transverse to the curing mat 11. The positions where the anti-slip materials 4 and 4 are attached are closer to the center of the curing mat 11 than the positions of the warning display portions 32 and 32 provided on the surface 3a side. In short, the anti-slip materials 4 and 4 are affixed to the back surface 3b of the curing mat 11 in a walkable range.

  Further, at the ends of the curing mats 11, 11 on both sides of the curing material 1 on the side of the connecting portion 12, the fastening portions 5 </ b> B, 5 </ b> B are provided on the back surface 3 b as well as the front surface 3 a. A method of using the retaining portion 5B will be described later.

  Next, the usage method of the curing material 1 is demonstrated, referring FIGS. 4-7. Below, as shown in FIG. 4, the case where the roof of a building is constructed | assembled using the roof panel 60 with which the some solar cell module 6, ... was assembled is demonstrated to an example.

  First, the curing material 1 is placed on the roof panel 60 assembled at the factory while being aligned. Here, the curing mat 11 is formed in the same size (planar shape) as the one solar cell module 6.

  Therefore, the alignment is performed by aligning the center of the curing material 1 with the center of the solar cell module 6 in the width direction (short side direction), and the connecting portion 12 of the curing material 1 is arranged at the joint between the solar cell modules 6 and 6. To be done.

  Further, on the water side of the roof panel 60, as shown in FIG. 5A, one curing mat 11 is arranged so as to jump out of the roof panel 60. In short, the curing mat 11 at the center of the curing material 1 is installed on the solar cell module 6 positioned on the uppermost side of the roof panel 60.

  And the band 51A as a wire is passed through the fastening portions 5A and 5A on the surface 3a side. A PP band made of polypropylene or the like can be used for the band 51A. The band 51A is disposed so as to surround the periphery of the solar cell module 6 (see FIG. 6). As a result, the curing mat 11 is fixed to the solar cell module 6.

  Subsequently, the curing mat 11 protruding from the roof panel 60 is stacked on the curing mat 11 fixed to the solar cell module 6 by performing valley folding at the connecting portion 12.

  Then, as shown in FIG. 5B, the two curing mats 11, 11 are laminated on the solar cell module 6 positioned on the uppermost water surface of the roof panel 60, and the back surface 3 b of the curing mat 11 is Will be exposed.

  And the band 51B as a wire is also passed through the fastening portions 5B and 5B on the back surface 3b side. This band 51B is also arranged so as to surround the periphery of the solar cell module 6, as shown in FIG.

  Thus, the roof panel 60 to which the curing material 1 is attached is conveyed from the factory to the construction site. And it is lifted with a crane and installed as a roof of a building.

  The roof of this building is constructed by arranging a plurality of roof panels 60,... As shown in FIG. On the other hand, in the vicinity of the joint between the roof panels 60, 60, there is a sbase for the solar cell module 6A that cannot be installed in the factory in advance, so the solar cell module 6A is installed on the roof.

  Since the curing mat 11 is not installed on the solar cell module 6A installed in the field in this way, the band 51B of the folded curing mat 11 of the curing material 1 attached to the underwater roof panel 60 is provided. And the curing mat 11 is opened and installed on the surface of the solar cell module 6A.

  Thus, installation work such as wiring connection is performed on the solar cell modules 6 and 6A on which the curing material 1 is spread. And after completion | finish of work, the band 51A is removed sequentially, and the curing material 1 is folded by bend | folding in the connection part 12, and it makes it the size which it is easy to carry, and takes it down from a roof.

  Next, the effect | action of the curing mat 11 and the curing material 1 of this Embodiment is demonstrated.

  In the curing mat 11 of the present embodiment configured as described above, the anti-slip material 4 is attached to the back surface 3b of the bag body 3 in which the core material 2 having a hollow structure is accommodated. Further, the core material 2 and the anti-slip material 4 are integrated with each other through the bag body 3.

  For this reason, even if it installs on smooth surfaces, such as a glass plate of the solar cell module 6, it is hard to produce a slip. Moreover, since it is formed in the mat shape by the bag body 3, handling is easy.

  Furthermore, since the curing material 1 of the present embodiment is connected to a plurality of curing mats 11 so as to be foldable at the connecting portion 12, it is folded to a size that is easy to handle during installation or removal. Can be summarized.

  In addition, if a plurality of curing mats 11,... Are connected, positioning is easier, the number of fixing points can be reduced, and shorter than when separate curing mats 11,. Since it can be installed or removed in time, it is easy to handle.

  Furthermore, by providing the fastening portions 5A and 5B into which the wire material can be inserted on the front surface 3a and the back surface 3b of the bag 3, it is easy to moor and fix the curing material 1 to the solar cell modules 6 and 6A. Thus, scattering of the curing material 1 due to wind can be prevented.

  Further, by forming the core material 2 from a synthetic resin material having a hollow structure such as Pradan, the weight can be reduced while ensuring a predetermined strength. Furthermore, even if the core material 2 has a hollow structure, since the core material 2 is accommodated inside the bag body 3, water does not accumulate or deteriorate and the strength does not decrease.

  Moreover, weight reduction can be achieved by forming the anti-slip | skid part with the anti-slip | skid material 4, ... stuck by spacing. That is, when a synthetic rubber sheet is affixed to the entire surface of the curing mat 11, the weight increases and it becomes difficult to handle, but if it is arranged at intervals, the weight can be reduced.

  And if the solar cell module 6 and 6A are covered with the curing material 1 in this way, it can prevent damaging and becoming dirty during work. Further, the curing material 1 that can be easily removed can be collected and used repeatedly.

  The embodiment of the present invention has been described in detail above with reference to the drawings. However, the specific configuration is not limited to this embodiment, and design changes that do not depart from the gist of the present invention are not limited to this embodiment. Included in the invention.

  For example, in the said embodiment, although solar cell module 6 and 6A were demonstrated as a protection target object, it is not limited to this. For example, a glass floor, a floor finished with a smooth surface, a floor easily damaged, or the like can be used as the object to be protected.

  Moreover, in the said embodiment, although the "pradan" formed by the synthetic resin material of a hollow structure was illustrated as a core material which has a space | gap inside, it is not limited to this. Any plate-like material that is reduced in weight by satisfying a predetermined strength while having a structure having voids inside can be used as a core material. For example, the core material having a hollow structure can be formed of aluminum material or cardboard. Moreover, the flat plate which contains many bubbles can also be used as a core material.

  Furthermore, in the said embodiment, although the anti-slip | skid part was formed by sticking the strip | belt-shaped anti-slip | skid material 4 at intervals, it is not limited to this. For example, the anti-slip portion can be formed by applying an anti-slip coating to the back surface 3 b of the bag body 3.

  And in the said embodiment, although the curing material 1 which connected the three curing mats 11 ... was demonstrated, it is not limited to this, Two or four or more curing mats 11, ... can also be used as a curing material.
