(2) Second embodiment (see FIGS. 10 and 11)
The sheet-like photovoltaic power generation module mounting method according to the present embodiment is the same as the first embodiment in terms of the basic configuration, and the arrangement structure of the frame 3 and the sheet-like photovoltaic power generation module 1 is the same. It differs from the first embodiment in that it is different.

  Therefore, here, the description will focus on an arrangement structure of the frame 3 and the sheet-like solar power generation module 1 that is different from the first embodiment.

  That is, in this embodiment, a “standard type” arrangement structure in which one frame 3 and the sheet-like photovoltaic power generation module 1 are arranged for one building member 5 employed in the first embodiment. It adopts a “cross-joint type” arrangement structure.

  As shown in FIG. 10, when the construction members 5 are provided in a butted state as shown in FIG. 10, two construction members 5 adjacent to the frame 3 and the sheet-like photovoltaic power generation module 1 are provided.

The structure is fixed only to one of the building members 5 and not fixed to the other building member 5. Accordingly, in this embodiment, a plate plate 63 for masking the frame 3 so that the adhesive J is applied to one building member 5 and the adhesive J is not applied to the other building member 5. Has been added. In the example of FIG. 10, the frame 3 is fixed to the upper building member 5 by the fixing screw 19 and the adhesive J is applied. However, the frame 3 is fixed to the lower building member 5 by the fixing screw 19. The adhesive agent J is not applied by the plate plate 63 without being fixed.

  The sheet-like photovoltaic power module mounting method according to the present embodiment having such a configuration also exhibits the same operations and effects as the first embodiment, and further, as a unique effect of the present embodiment, Since the inter-layer displacement 67 in the left-right direction of the building member 5 connected in a state where the frame 3 is a strength member and is abutted is absorbed as shown in FIG. 11, the earthquake resistance of the building member 5 and the photovoltaic power generation module is improved. Can be maintained and improved.

  FIG. 10A shows various modifications of the second embodiment. The plate plate 63 for masking so as not to apply the adhesive J to the building member 5 can be attached to a part or the entire surface of the frame 3. For example, as shown in FIG. 10A, the plate plate 63 straddles the vertical joint (the frame 3 on the upper left and right sides in FIG. 10A), or straddles both the horizontal joint and the vertical joint (in two directions). As if straddling the joints: middle frame 3 in FIG. 10A), it can be installed in an appropriate position in the frame 3 in an appropriate shape. Further, a plate plate 63 may be disposed on the entire surface of the frame 3 like the lower frame 3 in FIG. 10A. In the case where the plate plate 63 is not disposed on a part of the frame 3, the frame 3 is fixed to the building member 5 with the fixing screw 19 in a portion where the plate plate 63 is not present, but the plate plate 63 is disposed on the entire surface of the frame 3. Then, the frame 3 is fixed to any one building member 5 covered by the frame 3 with the fixing screw 19. In the lower frame 3 in FIG. 10A, the upper left building member 5 is fixed with a fixing screw 19.

According to the frame 3 (the frame 3 on both upper left and right sides in FIG. 10A) arranged so that the plate plate 63 straddles the vertical joint, it is possible to absorb the vertical interlayer displacement of the building member 5. Further, the frame 3 (the middle frame 3 in FIG. 10A) arranged so as to straddle both the horizontal joint and the vertical joint (so as to straddle the joint in two directions), and the frame in which the plate 63 is arranged on the entire surface. 3 (lower stage in FIG. 10A), it is possible to absorb the interlayer displacement in the horizontal direction and the vertical direction.

  In addition, as shown in FIG. 20, the external wiring 27a may be installed using a band-shaped base plate 91 provided with flange portions 91b on both sides of a U-shaped main body 91a. In this case, a predetermined number of belt-like base plates 91 are fixed on the building member 5 with screws 94 in the space 100 between the frames 3, and the external wiring 27 a is arranged in the wiring installation passage 100 a inside the belt-like base plate 91. The cover plate 92 is fixed to the flange portion 91b of the plate 91 with screws 95. Thereafter, a regular or irregular sealing material 93 is inserted or filled into the vertical joint between the cover plate 92 and the sheet-like solar power generation module 1. When using an irregular sealing material, for example, a backup material having a circular cross section is inserted in advance, and then the sealing material is filled.

  The above is the basic embodiment of the present invention, but the method for mounting the sheet-like photovoltaic power generation module of the present invention is not limited to the above-described embodiment, and does not depart from the gist of the present invention. It is possible to change or abbreviate | omit the partial structure inside or to add a well-known technique well-known to those skilled in the art.

  For example, the structures and materials of the sheet-like photovoltaic power generation module 1 and the frame 3 used in the present invention are not limited to the configurations described in the above embodiments, but sheets of various structures and materials that exhibit similar functions and effects. The solar photovoltaic module 1 and the frame 3 can be employed.

  FIG. 15 illustrates a frame 3A according to another embodiment in which the structure of the frame 3 is different. That is, the frame 3A shown in FIG. 15 is provided on the upper frame 7A and the lower frame 7B in place of the overhang regulating portion 12 provided on the left frame 7C and the right frame 7D in the above embodiment. Are provided in the left frame 7C and the right frame 7D.

  Even when such a frame 3A is employed, the same functions and effects as those of the first to third embodiments are exhibited, and the sealing performance on the left side C and the right side D of the sheet-like solar power generation module 1 is further improved. Since it increases, waterproofness and fireproof performance can be further improved. Also, the frame 3A of the present embodiment can apply the attachment methods according to the first and second embodiments, and can also apply the frame reinforcement step according to the third embodiment.

  In addition, the sizes of the frame 3 and the sheet-like photovoltaic power generation module 1 used in the present invention are not limited to the dimensions exemplified in the first to third embodiments, and can be changed to various sizes. is there.

  Further, when the building member 5 has a curved or bent shape, the shape of the frame 3 may be curved or bent according to the shape.

  According to the sheet-like photovoltaic power generation module mounting method according to the above embodiment, prior to the installation of the sheet-like photovoltaic power generation module, the building member includes the frame having a structure surrounding the side periphery of the sheet-like photovoltaic power generation module. Since a frame fixing process is provided in advance, the sheet-like photovoltaic power generation module can be attached in advance to the outer wall material before being attached to the building, as well as to the existing outer wall material etc. It is also possible to deal with renovation work that directly attaches a photovoltaic module on the site.

  Moreover, since the side peripheral part of a sheet-like photovoltaic power generation module is covered with the said flame | frame, fireproof performance improves. In addition, the provision of the above frame eliminates the need for adhesive curing applied in the adhesive application process, so anyone can easily and neatly attach the sheet-like solar power generation module to the outer wall material, etc. Become.

  Further, in the sheet-like module attaching step, the sheet-like photovoltaic power generation module is attached with the frame as a guide, so that the sheet-like photovoltaic power generation module is attached to the existing outer wall material or the like. Positioning can be performed easily even under the condition that the photovoltaic power generation module must be supported in a vertical posture, and the construction is quick and the work efficiency is improved because it is lightweight.

  Also, by adopting a frame with a structure surrounding the side periphery of the sheet-like photovoltaic module and a lightweight sheet-like photovoltaic module that does not have a glass plate, it is always possible to install a heavy object like an ALC panel. It is possible to carry out solar power generation renovation work even on building components that have a fragile surface with a dry paint finish.

  In addition, in the adhesive application step, the adhesive is applied not only to the mounting surface of the uneven building member to which the sheet-like solar power generation module is attached, but also to the flat mounting surface of the frame. In addition, the adhesive strength of the sheet-like photovoltaic module increases. Furthermore, the waterproofness and fireproof performance of the sheet-like photovoltaic power generation module are improved by adopting the sealing process.

  In addition, when the frame is disposed so as to straddle the joints between a plurality of adjacent building members, the frame serves as a strength member in the left-right direction and / or the up-down direction of the building member connected in a butted state. Since the interlayer displacement is absorbed, the earthquake resistance of the building member and the sheet-like photovoltaic power generation module can be maintained and improved.

  In addition, the layout of the frame that spans the joints is a sheet shape that is effective in the use of the surface area of the building material and has excellent design to enable continuous and free installation of the sheet-like photovoltaic power generation module that is not caught by the assignment of the outer wall member The layout of the photovoltaic module becomes possible.

  In addition, when the frame arranged so as to straddle the joint between two adjacent building members as described above is fixed to only one of the two building members, a new building is constructed. Work for assembling on-site a sheet-like photovoltaic power generation module that has been pre-installed on a building component prior to installation in the building for construction, etc., once installed The operation of removing the building member from the building member installed in the building is also easily performed.

  In addition, when the adhesive used in the adhesive application step is a modified silicone adhesive, it can adhere well to a building member having an uneven surface such as an ALC panel, and has high weather resistance. Therefore, a stable adhesive force can be expected over a long period of time.

  In addition, in the sheet-like module attaching step, when a light-shielding primer is applied to the light-transmitting portion of the sheet-like photovoltaic power generation module, the adhesive is prevented from deteriorating due to light transmission. The adhesive strength of the resin becomes more stable and lasts for a long time.

  Further, when a frame reinforcing step using a drop-preventing penetrating anchor is provided after the sealing step, it is caused by deterioration of a fixing screw for fixing the frame, cracking or peeling of a surface of a weak building member such as an ALC panel, etc. In the unlikely event that the frame is dropped, the safety during use of the sheet-like solar power generation module is improved.

  INDUSTRIAL APPLICABILITY The present invention can be used in a construction field in which a photovoltaic power generation facility is installed on a building member such as an outer wall material or a roof material of a building using a sheet-like photovoltaic power generation module. It is particularly useful for installation of solar power generation equipment that can cope with renovation work, has a short construction period, and has excellent fireproof performance when it cannot be reinforced or modified.
