Japanese Patent Application Laid-Open No. 2002-4526

In the prior art shown in FIG. 9, of the four sides of the solar cell module 6, only two sides, which are the short sides into which the seal member 31 is inserted, are fixed. Therefore, since the long side of the solar cell module 6 is not fixed, the fixing strength of the solar cell module 6 may be insufficient. In particular, when the solar cell module 6 is frameless and thin, there is a possibility that the long side will bend and come off.

The present application is a fixed structure of a plate-like body using a first support material and a second support material that are combined so as to be orthogonal to each other. On the longitudinal side surface of the first support material, a first holding portion formed by separating a pair of upper surfaces and lower surfaces by the thickness dimension of the plate-like body or more, and an engaged portion extending at a position lower than the first holding portion. Has been done. On the longitudinal side surface of the second support member, a second holding portion is extended, in which a pair of upper surfaces and lower surfaces are separated by a thickness dimension of a plate-like body or more. Further, an engaging portion is formed at an end portion of the second support member at a position lower than that of the second holding portion. When the engaged portion and the engaged portion are engaged, the upper surfaces of the first holding portion and the second holding portion are at substantially the same height, and the lower surfaces of the first holding portion and the second holding portion are connected to each other. Is characterized by having substantially the same height.

The fixed structure of the plate-shaped body of the present application is a state in which the edges of the four sides of the plate-shaped body are fixed. Therefore, since not only the short side but also the long side of the solar cell module 6 is fixed, the fixing strength of the plate-shaped body is higher than that of the prior art of FIG. In particular, even if the plate-shaped body is a frameless thin photovoltaic power generation module or the like, since the four sides are fixed, the structure is such that it does not easily bend and does not easily come off from the first support material and the second support material.

The present application is a fixed structure of a plate-shaped body B using a first support material X and a second support material Y that are combined so as to be orthogonal to each other. The plate-shaped body B is a substantially rectangular shape in a plan view having a predetermined thickness, such as a photovoltaic power generation module or a signboard. The plate-shaped body B of the present application is particularly suitable for a thin type such as a frameless photovoltaic power generation module. This is because the thin plate-shaped body B does not bend because the edges on all four sides are fixed, and the structure is such that it does not easily come off from the first support material X and the second support material Y.

In the present application, the first support material X and the second support material Y, which are combined so as to be orthogonal to each other, are long materials having a predetermined length. In this embodiment, the longitudinal side surface of the first support member X is combined with the edge end surface of the second support member Y. The length of each is arbitrary, but in this embodiment, the first support material X is longer than the second support material Y. Then, the long side end edge of the plate-shaped body B is arranged so that the longitudinal side surface of the first support member X and the short side end edge of the plate-shaped body B face each other with the longitudinal side surface of the second support member Y. Will be done.

In the first support material X of this embodiment, a first holding portion X1 is formed on a longitudinal side surface in which a pair of upper surfaces X1a and lower surfaces X1b are separated by a thickness dimension of a plate-shaped body B or more. In this embodiment, the first holding portion X1 is formed in a substantially U-shaped cross section, and the long side end edge of the plate-shaped body B is inserted.

In the first support material X of this embodiment, the engaged portion X2 is extended at a position lower than the first holding portion X1. In this embodiment, the engaged portion X2 is formed in a substantially U-shaped cross section in which the upper piece X2a and the lower piece X2b are projected, and the vertical movement of the second support member Y to be combined is restricted. It has a structure.

In the second support material Y of the present embodiment, a second holding portion Y1 formed by a pair of upper surface Y1a and lower surface Y1b separated by the thickness dimension of the plate-shaped body B or more is extended on the longitudinal side surface. In the present embodiment, the second holding portion Y1 is formed in a substantially U-shaped cross section, and the short side end edge of the plate-shaped body B is inserted.

In the second support member Y of this embodiment, the engaging portion Y2 is formed at a position lower than the second holding portion Y1 at the edge side end portion. In this embodiment, a notch is formed between the second holding portion Y1 and the engaging portion Y2 at the edge side end portion. When the engaged portion X2 and the engaged portion Y2 are engaged, the upper piece X2a of the engaged portion X2 formed in a substantially U-shaped cross section in the first support member X is inserted into this notch. ..

In this embodiment, when the engaged portion X2 and the engaging portion Y2 are engaged, the upper surfaces X1a and Y1a of the first holding portion X1 and the second holding portion Y1 have substantially the same height and the first The lower surfaces X1b and Y1b of the first holding portion X1 and the second holding portion Y1 have substantially the same height. Therefore, the edges of the four sides of the plate-shaped body B are fixed to the first holding portion X1 and the second holding portion Y1.

In this embodiment, the engaged portion X2 is extended to the first support member X at a position lower than the first holding portion X1, and the second support member Y is engaged at a position lower than the second holding portion Y1. A joint Y2 is formed. Therefore, the upper surfaces X1a and Y1a of the first holding portion X1 and the second holding portion Y1 have substantially the same height, and the lower surfaces X1b and Y1b of the first holding portion X1 and the second holding portion Y1 have substantially the same height. Can be abbreviated. Further, by setting the engaged portion X2 at a position lower than the first holding portion X1 and the engaged portion X2 at a position lower than the second holding portion Y1, the first support material X is formed on the back surface side of the plate-shaped body B. The second support member Y is engaged. Therefore, the structural portion to which the first support material X and the second support material Y are bonded does not appear on the surface side. Therefore, when the plate-shaped body B is a photovoltaic power generation module, sunlight is not blocked by the structural portion where the first support material X and the second support material Y are bonded, and sufficient power generation can be obtained. can.

For example, in the case of the prior art shown in FIG. 9, a structure is such that a substantially U-shaped portion of a sealing member is combined with a solar cell module and inserted into a substantially U-shaped portion of a module rail. Therefore, it is necessary to open the substantially U-shaped portion of the module rail larger than the substantially U-shaped portion of the seal member. As a result, of the end edges of the solar cell module, the side facing the module rail is not fixed. If the solar cell module is as thin as a frameless module, there is a risk that the unfixed edges will bend and come off. Even more, if the unfixed edge is on the long side, the risk is increased.

As in the embodiment shown in FIG. 7, the stop member T may be attached to the edge portion of the first support member X. By attaching the stopper member T, it is possible to prevent the second support member Y from coming off in the direction of the edge portion of the first support member X. Further, by setting the length of the first support material X in consideration of the dimensions of the plate-shaped body B and the second support material Y, a plate combined with the first support material X can be simply attached by simply attaching the stop member T. The shape B and the second support member Y can be fixed.

As in the embodiment shown in FIG. 8, the first support material X may be fixed to the base material K. The base material K is, for example, a roof mounting bracket, a pedestal for ground installation, or the like. In this embodiment, the base material K is formed with an insertion portion K1 opened laterally. In the case of this embodiment, the fastening leg X3 is formed on the first support material X, and is inserted into the insertion portion K1 of the base material K and combined.

In this embodiment, the first support material X is fixed to the base material K by using the pressing member O. In the present embodiment, the pressing member O has a substantially inverted L shape in which the pressing portion O1 is formed on the upper surface and the fixing portion O2 is formed on the side surface. Of these, the fixing portion O2 formed on the side surface is fixed to the base material K by a fastener F such as a bolt or a nut. When the fastener F is used laterally with respect to the pressing member O, there is no possibility that the fastener F will interfere with the second support member Y combined with the first support member X. For example, when the holding member O is fixed to the base material K from the upper surface by a fastener F such as a bolt or a nut, the tip or head of the bolt which is the fastener F protrudes upward, so that the second support is provided. There is a risk of interfering with the position of the material Y.

In this embodiment, the pressing member O is formed with a contact portion O3. In this embodiment, the abutting portion O3 is formed so as to project from the pressing portion O1 of the pressing member O toward the base material K side. By forming the abutting portion O11, when the pressing member O of the present embodiment is fixed by the fastener F, the abutting portion O3 abuts on the first support member X, and the fastening leg X3 is inserted. It is a structure that is pushed into the portion K1. Further, the contact portion O11 also plays a role of preventing the fastening leg X3 from coming off from the insertion portion K1 when the pressing member O is fixed to the base material K by the fastener F.
