  In FIG. 6A, it is difficult to replace the bolt that is the fixing means B protruding upward from the mounting body. For example, when it was desired to use bolts of different lengths, it was difficult to remove and reattach.

  In FIG. 6 (a), it is possible to realize the inclined installation of the installation on the roof, but there has been a demand for an improvement in which the installation is inclined in a more stable state.

  In the case of the combination shown in FIGS. 6A and 6A, the latching portion shown in FIG. 6A is directed downward, and is electrically connected by a protrusion formed there. For this reason, depending on the shape of the frame of the photovoltaic power generation panel, the photovoltaic power generation panels could not be conducted with a combination of these metal fittings. Accordingly, a metal fitting is manufactured according to the frame body, or a solar power generation panel used by the metal fitting is limited.

  The technique of FIG. 7 solves the problem relating to conduction in FIG. 6 described first. However, the crosspiece 8 in FIG. 7 is long, and the grounding fixtures 1 and 24 are used by sliding with respect to the upper side groove portion 10. First, an expensive long horizontal rail 8 is required, and it takes time and labor to insert a plurality of ground fixing brackets 1 and 24 from the side. It was difficult to position the grounding fixtures 1 and 24, and it took time and effort to install the grounding fixtures 1 and 24 at predetermined positions.

  FIG. 7 mainly relates to the grounding fixtures 1 and 24. For this reason, the attachment method to the roof of the horizontal rail 8 is not described. The horizontal beam 8 seems to be attached to cross the vertical beam fixed to the roof. A separate construction called a vertical beam was required, and it took time and effort to install the horizontal beam 8 there. Further, the horizontal beam 8 may be attached to a metal fitting attached to the roof without using the vertical beam. However, it took time and effort to mount the crosspiece 8 over a plurality of brackets.

  In FIG. 8, the wiring member 301 is fixed by fitting the closing member 201 to a horizontal rail or a vertical rail. For this reason, it has been troublesome to remove the wiring in order to retry. Moreover, since the direction of wiring is limited, for example, when it is used as a horizontal rail, it is difficult to wire in the direction of the eaves.

  When FIG. 9 is applied, it is conceivable to use a metal fitting such as the clip main body 10 and clamp it to the attachment metal using elasticity. However, since FIG. 9 is for a general shape steel, a technique relating to a metal fitting fixed to a roofing material or a metal fitting for attaching the clip body 10 has not been disclosed.

  In order to solve the problems described so far, the present application provides a fixing device for an installation on a roof, in which the fixing means can be easily exchanged, and a mounting body can be attached, and at the same time, conduction can be easily performed.

  First, an embodiment of the fixing device for roof installations according to the present application will be described with reference to FIGS. FIGS. 1 to 3 are explanatory views showing a mounting bracket A, a mounting body N, and a locking body D in the embodiment of the fixing device for a roof-mounted object of the present application. Next, the construction state of the fixing device of the present application will be described with reference to FIGS. FIG. 4 is an explanatory diagram of an embodiment in which a tube material support H is combined with the mounting body N of FIG. FIG. 5 is an explanatory view of an embodiment showing a state in which the photovoltaic power generation panel T is fixed by using the fixing device for an installation on the roof of the present application.

  The mounting bracket A of the present embodiment shows an embodiment in the case where the mounting bracket A is mounted on a vertical roofing material R, and is composed of the following members. First, the sandwiching body M will be described. The clamping body M has clamping parts M1 and M1 facing each other. The clamping body M is configured to be opened and closed by the rotation axis J, and the ridges of the vertical roof are clamped by the clamping means S and clamped by the clamping parts M1 and M1. The holding body M is connected to the connecting portions N5 and N5 of the mounting body N by the rotation axis J.

  In the present embodiment, the mounting body N has a locking body holding portion N2 extending in the direction of the row and mounting portions N1 and N1 on both sides thereof on the upper surface. The placement unit N1 may be on one side. The photovoltaic power generation panels TT which are installation objects on a roof are mounted in this mounting part N1 * N1. The locking body holding part N2 is formed in the central part of the upper surface of the mounting body N, and has opposing groove parts N3 and N3. The bottom surface of the locking body holding portion N2 has a width that can hold the bolt head or the nut, which is the fixing means K combined with the locking body D described later, in a non-rotating state. The groove portions N3 and N3 serve as guide grooves for inserting the elevation surface portions D3 and D3 of the locking body D from the side. The upper end edges of the grooves N3 and N3 are shaped to prevent the locking body D from being pulled upward.

  In the case of the present embodiment, a holding portion N4 is formed. The holding portion N4 is formed on a lower side surface than the placement portion N1. In the present embodiment, a holding portion N4 is formed on the side of the mounting portion N1 and N1 on the side of the eaves side in parallel with the locking body holding portion N2. The holding means N for the tube material support H is held by the holding portion N4. In the case of FIG. 1, the holding portion N4 has a groove shape, and is formed in a shape that holds the head and nut of the mounting bolt as the fixing means K in a non-rotating state. As shown in FIG.4 and FIG.5, the pipe material support H is attached to this attachment bolt. In the case of the present embodiment, the tube material support H has a side surface with a substantially L-shaped cross section, and forms a mounting portion to the holding portion N4 and a hole that is a mounting portion of the tube material support H. Yes. By changing the direction of the attachment portion, the position at which the pipe material support H is attached to the holding portion N4 can be changed.

  Further, the locking body D is detachably combined with the locking body holding portion N2 of the mounting body N. In the case of the present embodiment, the locking body D has a flat surface portion D2 and rising surface portions D3 and D3 that are formed by raising two opposite sides of the flat surface portion D2. An insertion hole D2a is formed in the plane portion D2, and the fixing means K is combined. The other two opposite sides of the flat surface portion D2 are folded at one side to form a folded portion D5. On the folded part D5, upward projections D1 and D1 are formed. Abutting portions D4 and D4 are formed on the other side of the folded portion D5. In addition, when the photovoltaic power generation panels T and T which are installation objects on a roof are made to conduct | electrically_connect by the upward protrusion D1, the latching body D must have electroconductivity.

When the locking body D is inserted to an appropriate position with respect to the locking body holding portion N2, the contact portions D4 and D4 contact the side surface of the mounting body N. The other side of the contact portions D4 and D4 is a fold-down portion D5 and contacts the side surface of the mounting body N. Positioning on the side surface of the mounting body N is performed by the contact portions D4 and D4 of the locking body D and the folded-down portion D5 serving as the contact portion. Therefore, the positions of the locking body D and the fixing means K with respect to the locking body holding part N2 are easily determined. When it is desired to replace the fixing means K later, the abutment of the contact portions D4 and D4 and the folding portion D5 of the locking body D can be released, and the fixing means K can be easily replaced. The shape of the contact portion between the side surface of the mounting body N and the locking body D may be any shape as long as the locking body D is detachable from the locking body holding portion N2.

In the embodiment described so far, the locking body holding portion N2 is a groove having an upper surface opened. Further, the groove has a width that can prevent the bolt head penetrating upward from the locking body D from being turned. However, the locking body holding part N2 should just have the length with which the locking body D is contact | abutted at least in the crossing direction in a roof . It is conceivable that the locking body holding portion N2 is not shaped to open upward, but has a substantially T-shaped cross section or a substantially hat shape. And the latching body D is also combined with the latching body holding | maintenance part N2, and makes it the shape positioned by making it contact | abut at least in the crossing direction in a roof in the mounting body N. FIG.

In the case of the present embodiment, the locking body holding portion N2 has a groove shape and is also positioned in the eaves-ridge direction. In this way, it is desirable to have a shape that can also be positioned in the eaves-ridge direction. In the case of the present embodiment, the groove portions N3 and N3 of the locking body holding portion N2 have upper surfaces facing each other. For this reason, when the locking body D is pulled upward by the fastening means K being tightened, it can be firmly fixed. This is because the rear surface side of the upper surface serves as an abutting portion, and the locking body D (the upper edge of the upright portions D3 and D3 in this embodiment) abuts.

  Furthermore, the solar power generation panel T, which is an installation object on the roof, is installed at an inclination by forming an inclination in which the engaging body holding part N2 side of the mounting part N1 and the opposite edge side thereof are at different heights. it can. When the mounting body N is tilted by the rotation axis J as in the present embodiment, the tilt is formed in the direction in which the mounting body N does not tilt.

  Subsequently, the combination of the members described so far will be described. The sandwiching body M is combined with the sandwiching portions M1 and M1 facing each other and the fastening means S passing through the side surfaces. Then, the mounting body N is put on the sandwiching body M, and the connecting body N5 and N5 of the sandwiching body M and the mounting body N are connected by the rotation shaft J. The locking body D is combined with the locking body holding portion N2 of the mounting body N. In the case of the present embodiment, an insertion hole D2a is formed in the flat surface portion D2 of the locking body D, and a bolt as the fixing means K is combined upward. Each of the raised portions D3 and D3 of the locking body D is combined by inserting the groove portions N3 and N3 of the locking body holding portion N2 as guide grooves. In this manner, the sandwiching body M, the mounting body N, and the locking body D can be shipped in combination with the mounting bracket A in a state where the sandwiching body M, the mounting body N, and the locking body D are integrated.

  Next, the construction state of the fixing device of the present application will be described. First, the clamping parts M1 and M1 of the clamping body M of the mounting bracket A are opened and covered with the ridges of the roof material R and R, and are clamped by the clamping means S to clamp the ridges. Next, the photovoltaic power generation panels TT which are installation objects on a roof are mounted on each mounting part N1 * N1 of the mounting body N. FIG. In the case of a present Example, it is good to make the photovoltaic power generation panel T along the elevation surface of the latching body holding | maintenance part N2. When the photovoltaic power generation panels T and T are mounted, the mounting body N is moved by the rotation axis J and then becomes flat. In this state, the holding fixture O is combined to form a fixing device.

  In the case of the present embodiment, the holding metal fitting O has a shape that opens upward. Then, a bottom surface portion O1 having a hole, side surface portions O2 and O2 that are raised on two opposite sides, and pressing portions O3 and O3 are formed by bending the respective side surface portions O2 and O2 outwardly. Yes. The bottom surface portion O1 of the presser fitting O is inserted between the adjacent photovoltaic power generation panels T and T, and the pressing portions O3 and O3 are placed on the upper surfaces of the frame bodies of the photovoltaic power generation panels T and T. At this time, since the fixing means K protrudes from the positioned locking body D, the presser fitting O can be easily attached. The presser fitting O is shaped to match the shape of the photovoltaic power generation panel T.

Next, the bolt protruding from the locking body D is tightened using a nut. The locking body D is pulled up by the tightened bolts, the elevations D3 and D3 hit the grooves N3 and N3, and the upward projections D1 and D1 are applied to the photovoltaic power generation panels T and T, which are installed on the roof, from below. Bite. The groove portions N3 and N3 of this embodiment have some clearance in the upper part on the inner side where the elevation portions D3 and D3 are combined. The locking body D to be combined there is positioned with respect to the direction of the column in the roof . Therefore, when the locking body D is pulled up with a bolt, the upper end edges of the rising surface portions D3 and D3 serve as fulcrums with respect to the groove portions N3 and N3, and the protrusions D1 and D1 can be securely bited.

  In the case of a present Example, the adjacent photovoltaic power generation panel T * T is electrically connected by the latching body D by making the protrusion D1 * D1 bite. In addition, the solar power generation panels T and T may be electrically connected to each other by combining the engaging body D with other conduction means such as a ground wire.

  Furthermore, when the mounting portion N1 forms an inclination, the photovoltaic power generation panel T that is an installation object on the roof can be installed at an inclination. In this case, fixing devices having different heights are used. At this time, you may attach with the fixing device of this application from which the height from the rotating shaft J to the mounting part N1 differs, and it is good also considering only a lower one or a higher one as a fixing device of this application. In addition, the lower one may be the fixing device of the present application, and the higher one may be configured by attaching a pedestal on the fixing device of the present application.

  In the case where the lower one is the fixing device shown in the present embodiment, the upright surface of the locking body holding portion N2 becomes non-slip, and the roof installation object is prevented from sliding down in the inclined direction. Thus, it can be installed in a stable state.

  Thus, when the photovoltaic power generation panel T which is an installation object on a roof is fixed to the mounting part N1 of the mounting body N, the following effects are exhibited. First, the locking body D is already combined with the mounting body N and positioned by the respective contact portions. For this reason, the bolt (fixing means) can be set to an appropriate position without moving the locking body D and positioned, and if the bolt protruding upward is tightened with a nut, it is simple and reliable. Can be conducted. Conversely, the nut may be combined with the locking body D and tightened with a bolt.

  The mounting bracket A of the present application is combined with a roofing material or the like. For this reason, what is necessary is just to mount on-roof installation objects, such as the photovoltaic power generation panel T, on the mounting body N of the mounting bracket A attached to the roofing material. As shown in FIG. 7, neither a long vertical rail nor a long horizontal rail intersecting with it is required, and the trouble of attaching them is unnecessary. And the frame of the photovoltaic power generation panel T which is an installation object on a roof can be easily conduct | electrically_connected by the latching body D combined with the mounting body N. FIG.

  In the case of the present embodiment, the above-described holding portion N4 has a groove shape, and the bolt head or nut as the fixing means K can be prevented from rotating. However, the holding part N4 may have other shapes. For example, you may form the recessed part which can make a volt | bolt head and a nut non-rotating state, or may fit another part into the holding | maintenance part N4.

  In the embodiments described so far, the mounting bracket A has been described as being attached to the protrusions of the vertical roofing material R. However, it is also possible to manufacture the mounting bracket A according to a roofing material such as that on the side, and to combine the mounting body N and the locking body D with it. Furthermore, the mounting body N can be combined obliquely with respect to the mounting bracket A on the roofing material. Moreover, the fixing means K combined with the insertion hole D2a of the latching body D fixes the photovoltaic power generation panel T which is an installation object on a roof. In the present embodiment, the fixing means K also has a role of pulling up the locking body D and causing the protrusions D1 and D1 to bite into the frame of the photovoltaic power generation panel T. However, the means for pulling up the locking body D may be different from the fixing means K.

  Moreover, in the Example described until now, the case where the installation object on the roof was the photovoltaic power generation panel T demonstrated. When the installation on the roof is a photovoltaic power generation panel, it is possible to easily realize the conduction between the photovoltaic power generation panels T and T, and the installation can be performed with an inclination to increase the incident angle of sunlight. Is big. However, in the present application, the photovoltaic power generation panel T is only an example of an installation on the roof. The on-roof installation in the present application refers to a general thing mounted on the roof, and may be a solar heat collecting panel, a signboard, etc. in addition to the photovoltaic power generation panel T shown in the present embodiment.

  Furthermore, in the embodiment described so far, the bolt as the fixing means K simply protrudes upward from the insertion hole D2a of the flat surface portion D2 of the locking body D. And it is hold | maintained at the latching body holding | maintenance part N2 in the rotation prevention state. Such a locking body D is positioned on the locking body holding portion N <b> 2 of the mounting body N in the column direction. For this reason, contact | abutting is cancelled | released, the latching body D can be removed from the latching body holding | maintenance part N2, and a bolt can be replaced | exchanged easily. In contrast, in the case of FIG. 7, bolt fixing portions are formed on the grounding fixtures 1, 24, and bolts are screwed or welded thereto. A plurality of such earth fixing brackets 1 and 24 are inserted into the horizontal rail. For this reason, it is difficult to replace the bolt.
