Japanese Unexamined Patent Publication No. 2015-227576

When installing an installation on the roof, it is desirable to prevent water from entering the room from the installation location of the installation. In Patent Document 1, a water stop plate is provided in order to prevent water from entering the room from the place where the installation object is installed. Therefore, the fixing structure described in Patent Document 1 requires at least a water stop plate, an installation metal fitting fixed on the water stop plate, and a vertical member fixed on the installation metal fitting.

When the number of parts for fixing the installation object is large in this way, the construction procedure of the installation object becomes complicated. In particular, installations that are mounted on a sloping roof, such as solar cell modules, are constructed in places where the scaffolding is not stable, so it is desirable to use fixtures that can be easily constructed.

Therefore, a fixture that can suppress the intrusion of water from the installation location and simplify the construction of the installation object is desired.

The fixture according to one aspect is a fixture for fixing an installation object on an inclined installation surface. This fixture projects toward the installation surface, the plate portion placed on the installation surface, the loading portion on which the installation object or the support member supporting the installation object is loaded, and the inclination of the installation surface. It has a water stop that extends along the direction. The plate portion, the loading portion, and the water blocking portion are integrally formed.

According to the above aspect, it is possible to provide a fixture capable of suppressing the intrusion of water from the installation location and simplifying the construction of the installation object.

It is a figure for demonstrating the step which follows FIG.

Hereinafter, embodiments will be described with reference to the drawings. In the drawings below, the same or similar parts are designated by the same or similar reference numerals. However, it should be noted that the drawings are schematic and the ratio of each dimension may differ from the actual one.

FIG. 1 is a schematic view showing an installation structure of an installation object according to an embodiment. FIG. 2 is a cross-sectional view taken along the line 2A-2A of FIG. In this embodiment, the installation object is a panel-shaped module 10 such as a solar cell module.

The panel-shaped module 10 is installed on an installation surface 50 inclined from a horizontal plane. Examples of such an installation surface 50 include a slate roof and an asphalt single roof.

In the example shown in FIG. 1, a plurality of panel-shaped modules 10 are arranged side by side in the vertical direction F1 and the horizontal direction F2. Here, the "vertical direction" corresponds to the inclination direction of the installation surface 50, that is, the direction connecting the water upper side and the water lower side of the installation surface. Further, the "horizontal direction" corresponds to a direction orthogonal to the vertical direction F1 in a plane parallel to the installation surface 50. Not limited to the example shown in FIG. 1, the panel-shaped modules 10 may be arranged along only one of the vertical direction F1 and the horizontal direction F2, and only one panel-shaped module 10 may be installed.

Further, in FIG. 1, the installation surface 50 is drawn flat, but the installation surface 50 may be a surface having a step, for example, a slate roof or an asphalt single roof. As shown in FIGS. 2 and 4, the installation surface 50 may be composed of a plurality of covered roofing materials 54. In this case, the plurality of roofing materials 54 are arranged in the vertical direction F1 and the horizontal direction F2, respectively.

As an example, the roofing materials 54 may be arranged so as not to overlap each other in the horizontal direction F2, and may be arranged so as to partially overlap each other in the vertical direction F1 (see FIGS. 2 and 4).

The panel-shaped module 10 is supported by the support member 100, and the support member 100 is fixed to the installation surface 50 by the fixture 100. In this embodiment, each panel-shaped module 10 is supported by two support members 100.

More specifically, each panel-shaped module 10 is supported by a support member 100 on both sides facing each other. In the present embodiment, each support member 100 supports the end side of the panel-shaped module 10 extending along the lateral direction F2. It is preferable that each support member 100 extends over the entire panel-shaped module 10 in the lateral direction F2.

The support member 100 may have a first loading portion 126a and a second loading portion 126b (see FIG. 2). The first loading portion 126a and the second loading portion 126b are configured to support the end sides of the panel-shaped module 10 from below. The first loading portion 126a and the second loading portion 126b may extend in the lateral direction F2 along the end edge of the panel-shaped module 10.

The support member 100 may have a side contact portion 128 that separates the first loading portion 126a and the second loading portion 126b. The side contact portion 128 is arranged between the pair of panel-shaped modules 10 loaded on the first loading portion 126a and the second loading portion 126b, and is attached to the frame 12 located at the end edge of the pair of panel-shaped modules 10. It may be configured to abut.

The support member 100 may have a flange 129. The flange 129 covers at least a part of the upper surface of the frame 12 of the pair of panel-shaped modules 10 loaded on the first loading portion 126a and the second loading portion 126b. Therefore, the flange 129 may project from the upper portion of the side surface contact portion 128 to both sides in the vertical direction F1 so as to cover the upper surface of the frame 12 of the panel-shaped module 10. The flange 129 may extend in the lateral direction F2 along the end edge of the panel-shaped module 10, similarly to the first loading portion 126a and the second loading portion 126b.

The frame 12 of each panel-shaped module 10 is sandwiched between the flange 129 and the first loading portion 126a or the second loading portion 126b. As a result, the end sides of each panel-shaped module 10 are held.

The support member 100 may have a connector 200 for connecting the support member 100 to a fixture 300 described later. FIG. 3 is a perspective view of a connector 200 constituting a support member 100 that supports an installation object.

The connector 200 may be configured to be detachable from the main body of the support member 100. Specifically, the support member 100 may have an engaged portion 124 that can be engaged with the connector 200. On the other hand, the connector 200 may have an engaging portion 224 that engages with the held portion 124.

In the embodiment shown in FIGS. 2 and 3, the engaging portion 224 of the connector 200 is formed by a groove extending in the lateral direction F2, and the engaged portion 124 of the support member 100 can be fitted into the groove. It is composed of protrusions extending in the lateral direction F2. As a result, the connector 200 is attached to the engaged portion 124 of the support member 100 by sliding from the lateral direction F2.

Further, the root portion of the protrusion as the engaged portion 124 of the support member 100 is thinner than the tip of the protrusion, whereby the engaged portion 124 is in the vertical direction (direction orthogonal to the installation surface). Is configured so as not to come off the groove as the engaging portion 224 of the connector 200.

The connector 200 may have a bottom 210 placed on the fixture 300, which will be described later, and a fixing plate 230 having a hole 232 through which a second fastening member 400 for fastening the fixture 300 passes. The fixed plate portion 230 is a plate-shaped portion that extends in a direction generally along the installation surface 50.

The connector 200 may be provided only at a position where it is fixed to the fixture 300, which will be described later. In this embodiment, two connecting tools 200 are provided for each support member 100. Instead, three or more connecting tools 200 may be provided for each support member 100.

Further, in the above embodiment, the connector 200 is configured to be detachably attached to the engaged portion 124 of the support member 100. Instead, the connector 200 may be configured inseparably from the main body of the support member 100. In this case, the bottom of the support member 100 may have a plate-shaped portion having a hole 232 through which the second fastening member 400 for fastening to the fixture 300 passes.

FIG. 4 is a top view of the fixture according to the embodiment. FIG. 5 is a perspective view of the fixture according to the embodiment. FIG. 6 is a plan view of the fixture as seen from the direction of arrow 6A in FIG. FIG. 7 is a side view of the fixture as seen from the direction of arrow 7A in FIG.

The fixture 300 may have a plate portion 310 placed on the installation surface 50, a loading portion 320 on which the support member 100 is loaded, and a water blocking portion 330. The plate portion 310, the loading portion 320, and the water stop portion 330 are integrally formed.

The plate portion 310 may have a through hole 312 penetrating the plate portion 310. The first fastening member 500 is attached to an installation surface 50 such as a roofing material 54 through a through hole 312. As a result, the fixture 300 is fixed to the installation surface 50.

A waterproof material 360 may be provided on one surface of the fixture 300 that faces the installation surface of the fixture 300, which is an area where the through hole 312 is provided. Specifically, the waterproof material 360 may be provided on at least one surface of the plate portion 310 or the spacer 340 described later on the installation surface side. The waterproof material 360 may be made of an elastic material such as a sheet-shaped rubber member. Such a waterproof material 360 may be composed of, for example, a butyl rubber-based adhesive tape. The waterproof material 360 can prevent water flowing through the installation surface 50 from entering the holes formed in the installation surface 50 by the first fastening member 500.

The waterproof material 360 may be provided at least around the through hole 312. Further, the waterproof material 360 may be provided at least from the periphery of the through hole 312 to the region extending in the lateral direction F2 from the region around the through hole 312. More preferably, the waterproof material 360 may extend from one end to the other end of the plate portion 310 and / or the spacer 340 described later in the lateral direction F2. As a result, the intrusion of water from the inclined direction can be further suppressed. The waterproof material 360 may be provided so as to close the through hole 312 before the first fastening member 500 penetrates the through hole 312.

The loading portion 320 of the fixture 300 may be configured to support the support member 100, more specifically the connector 200 of the support member 100. In the present embodiment, the loading portion 320 is a rail composed of a pair of protruding portions that continuously project upward from the plate portion 310 and extend in the vertical direction F1. The bottom of the connector 200 abuts on this rail.

The head 410 of the second fastening member 400 may be arranged in the space between the pair of protrusions constituting the loading portion 320 (see also FIG. 2). The screw portion 420 of the second fastening member 400 extends upward from the pair of protrusions constituting the loading portion 320, and further upward through the hole 232 provided in the fixing plate portion 230 of the connector 200. It is extending. That is, the rail constituting the loading portion 320 has a receiving portion 350 that receives the head 410 of the second fastening member 400 and projects the screw portion 420 of the second fastening member 400 in the direction away from the installation surface 50. The diameter of the head 410 of the second fastening member 400 is larger than the diameter of the screw portion 420.

A nut 430 is attached to the threaded portion 420 of the second fastening member 400. The nut 430 is provided on the upper side of the fixing plate portion 230 of the connector 200. Therefore, the connecting tool 200 and the fixing tool 300 are firmly fixed by fastening with the second fastening member 400.

The loading portion 320 and the receiving portion 350 may extend along the vertical direction F1. As a result, in a state where the second fastening member 400 is loosened, the support member 100 and the connecting tool 200 on the loading portion 320 are configured to be slidable in the vertical direction F1 together with the second fastening member 400. Thereby, the position of the support member 100 in the vertical direction F1, that is, the installation position of the panel-shaped member 10 in the vertical direction F1 can be finely adjusted.

The fixture 300 may have a pair of wall portions 370 erected above at a position inside the both ends in the lateral direction F2 and outside the rails constituting the loading portion 320. The wall portion 370 may extend in the vertical direction F1 like the loading portion 320. It is preferable that the height of the wall portion 370 is substantially the same as the height of the loading portion 320. As a result, the fixture 300 can support the connector 200 by both the loading portion 320 and the wall portion 370.

The water stop portion 330 is configured to project toward the installation surface 50 and extend along the vertical direction F1. As a result, when the fixture 300 is placed on the installation surface 50, the water stop portion 330 comes into contact with the installation surface 50.

Preferably, the water stop portion 330 projects toward the installation surface 50 side from the bottom surface of the plate portion 310. As a result, when the fixture 300 is placed on the installation surface 50, the water stop portion 330 comes into contact with the installation surface 50 more strongly.

The water stop portion 330 is provided outside the first fastening member 500 that penetrates the plate portion 310, that is, the through hole 312 in the lateral direction F2. Preferably, the water stop portion 330 is provided at the end of the fixture 300 in the lateral direction F2.

Since the water stop portion 330 extending along the vertical direction F1 comes into contact with the installation surface 50, water flows from the horizontal direction F2 between the fixture 300 and the installation surface 50, more specifically at the through hole 312. Invasion can be suppressed.

It is preferable that an elastic portion 332 that continuously extends from the plate portion 310 to the water stop portion 330 is provided. The elastic portion 332 may be integrally formed with the water stop portion 330 and the plate portion 310. The elastic portion 332 is configured to be elastically deformable in response to an external force in a direction intersecting the installation surface 50.

In the present embodiment, the elastic portion 332 is a portion extending in the lateral direction F2 from the plate portion 310, and at least a part of the elastic portion 332 is provided at a position away from the installation surface 50. More preferably, the thickness of the elastic portion 332 is thinner than the thickness of the plate portion 310.

By bending the elastic portion 332 described above, the water blocking portion 330 can come into contact with the installation surface 50 more strongly. In particular, if the water stop portion 330 projects toward the installation surface 50 side from the bottom surface of the plate portion 310, the elastic portion 332 bends by fastening the fixture 300 to the installation surface 50 with the first fastening member 500. At the same time, the water stop portion 330 comes into contact with the installation surface 50 more strongly. As a result, it is possible to further prevent water from entering between the fixture 300 and the installation surface 50 from the lateral direction F2.

In the thickness direction of the plate portion 310, the distance L2 between the bottom surface of the plate portion 310 and the tip of the water stop portion 330 on the installation surface side is, for example, about 0.2 mm to 5 mm, preferably about 0.5 mm to 3 mm. Good (see Figure 6).

In the aspect shown in FIG. 6, the elastic portion 332 is composed of a portion continuously extending from the plate portion 310 in the lateral direction F2. Instead, the elastic portion 332 may extend upward from the plate portion 310 once, and then be bent in the lateral direction F2 and extend in the lateral direction F2. In this case, the height of the elastic portion 332 from the plate portion 310 is preferably lower than the height of the loading portion 320 and the pair of wall portions 370 from the plate portion 310. However, from the viewpoint of facilitating the manufacture of the fixture 300, it is preferable that the elastic portion 332 extends in the lateral direction F2 from the side portion of the plate portion 310, as shown in FIG.

Here, the surface of the asphalt single roof contains fine irregularities. In the fixture 300 of the present embodiment, since the water blocking portion 330 strongly abuts on the surface of the asphalt single roof, it is possible to suppress the intrusion of water even if such fine irregularities are present. Therefore, the fixture 300 of the present embodiment is more effective when installed on an asphalt single roof.

As shown in FIG. 5, it is preferable that the end portion 334 on the water side of the elastic portion 332 is bent so as to abut the installation surface 50. In other words, the bottom surface of the water upper end portion 334 of the elastic portion 332 is configured to be substantially flush with the bottom surface of the plate portion 310. As a result, the entire end of the fixture 300 on the water side comes into contact with the installation surface 50, so that it is possible to suppress the intrusion of water from the water side in the vertical direction F1.

As described above, when the installation surface 50 is composed of a slate roof, an asphalt single roof, or the like, the installation surface 50 has a step along the inclination direction. This step corresponds to the position of the edge of the roofing material 54 in the vertical direction F1 (see FIGS. 2 and 4).

The fixture 300 of the present embodiment may be arranged so as to straddle a step of the installation surface 50 in the vertical direction F1. In this case, as shown in FIGS. 2 and 7, a spacer 340 corresponding to the height of the step may be provided in a part of the area on the installation surface side of the plate portion 310 of the fixture 300. For example, the height of the spacer 340 may correspond to the thickness of the roofing material 54. As a result, as shown in FIG. 2, the fixture 300 is stably installed across the step of the installation surface 50.

When the fixture 300 is arranged so as to straddle the step of the installation surface 50, the through hole 312 through which the first fastening member 500 penetrates has a region corresponding to a certain roof material 54 and a vertical direction with respect to the roof material 54. It is preferable that the area corresponding to the roof material 54 adjacent to the F1 is provided on both sides. As a result, the fixture 300 can be fixed to the roofing material 54 adjacent to each other in the vertical direction F1, so that the fixture 300 can be made more stable. Further, in this case, the through hole 312 located on the underwater side of the fixture 300 may also penetrate the spacer 340.

Further, in the vertical direction F1, it is preferable that the distance L1 from the water upper end portion of the fixture 300 to the spacer 340 is substantially equal to the distance between the plurality of steps provided on the installation surface 50. As a result, the fixture 300 can be installed so that the end portion of the fixture 300 on the water side comes into contact with the roof material 52 on the water side of the roof material 52 on which the fixture 300 is installed.

When the spacer 340 described above is provided, the water stop portion 330 may extend from the water upper end portion of the fixture 300 to at least the water upper end portion of the spacer 340 in the vertical direction F1. However, the water stop portion 330 may extend from the water upper end portion of the fixture 300 to the water lower end portion.

Further, it is preferable that the rail constituting the loading portion 320 described above is longer than the distance between the plurality of steps provided on the installation surface 50 in the vertical direction F1. As a result, the position of the support member 100 in the vertical direction F1 can be flexibly changed without being restricted to the step position on the installation surface 50.

FIG. 8 is a diagram for explaining a construction procedure of the installed object. FIG. 9 is a diagram for explaining the steps following FIG. It should be noted that the construction procedure described below is an example and the present invention is not limited thereto.

First, a panel-shaped module 10 as an installation object, a support member 100, and a fixture 300 are prepared. First, the fixture 300 is installed in a region that roughly matches the position of the end side of the panel-shaped module 10 to be installed in the vertical direction F1. Two fixtures 300 may be installed on one side of the panel-shaped module 10 on the water side, and two fixtures 300 may be installed on one side of the panel-shaped module 10 on the water side.

Here, when the installation surface 50 is a slate roof or an asphalt single roof, it is preferable to arrange the fixture 300 across the roof material 54 adjacent to the vertical direction F1 as described above.

Next, the support member 100 is mounted on the loading portion 320 of the fixture 300. The support member 100 is preferably fixed to the fixture 300 by the connector 200 described above. The connector 200 may be attached to the main body of the support member 100 in advance.

Here, after fixing the fixture 300 to the installation surface 50, the support member 100 is attached to the fixture 300. Instead, the fixture 300 may be fixed to the installation surface 50 with the fixture 300 attached to the support member 100 first.

After installing the support member 100, the panel-shaped module 10 is attached to the loading portions 126a and 126b of the support member 100. At this time, after attaching one end side of the panel-shaped module 10 to one support member 100, the other end side of the panel-shaped module 10 may be attached to another support member 100.

At this time, when the distance between the support members 100 in the vertical direction F1 is arranged to be slightly longer than the length of the panel-shaped module 10 in the vertical direction F1, and then the panel-shaped module 10 is held by the loading portions 126a and 126b. The position of the support member 100 in the vertical direction F1 may be adjusted. This position adjustment can be realized by sliding the support member 100 and the connecting tool 200 with respect to the fixing tool 300 in the vertical direction F1 in a state where the second fastening member 400 is loosened. As a result, the panel-shaped module 10 can be easily fitted into the loading portions 126a and 126b.

In the fixture 300 described in the above embodiment, the water stop portion 330 for suppressing the intrusion of water and the loading portion 320 for loading the support member 100 are integrally configured. That is, it is not necessary to configure the member having a water blocking function and the member having the function of the loading unit 320 for loading the installed object as separate members from each other. Therefore, the number of parts for fixing the installation object is reduced, and the construction of the installation object such as the panel-shaped module 10 is simplified.

As mentioned above, although the content of the invention has been disclosed through embodiments, the statements and drawings that form part of this disclosure should not be understood to limit the invention. This disclosure reveals to those skilled in the art various alternative embodiments, examples and operational techniques. Therefore, the technical scope of the present invention is defined only by the matters specifying the invention relating to the reasonable claims from the above description.

For example, in the above embodiment, the installation object installed outdoors is a panel-shaped module 10 such as a solar cell module, but the present invention is not limited to this.

Further, the support member 100 is not limited to the above-mentioned structure, and may have any structure as long as it can support the installed object. Further, if possible, the fixture 300 may directly fix the installed object without using the support member 100. In this case, the loading unit 320 of the fixture 300 may be configured to directly load the installed object.
