Description

  TECHNICAL FIELD The present invention relates to a metal fitting for attaching an installation object on a roof such as a photovoltaic power generation panel or a supporting member thereof on a roof tile roof.

  The prior art will be described with reference to FIGS. FIG. 6 shows the technique described in Japanese Patent Application Laid-Open No. 2010-285799, and FIG. 7 shows the technique described in Japanese Patent No. 3332327.

  FIG. 6 includes a first clamping member having a bowl-shaped holding part that is a concave depression that houses the side-clamping connecting part of the folded-plate roof, and a bowl holding surface that is positioned below the bottle-holding part. It consists of the 2nd clamping member which has the collar holding part made into the concave hollow like the clamping member, and the collar clamping surface, and the clamping tool which adjoins and separates the 1st clamping member and the 2nd clamping member. A characteristic folded-plate roof power frame is described.

JP 2010-285799 A Japanese Patent No. 3332327

  The folded plate roof power frame shown in FIG. 6 is attached to the roof with the first and second holding members. At this time, one clamping state affects the other clamping state. For example, the case where the magnitude | sizes of the two clamp fastening parts differ by a dimension error and a construction error is assumed. In this case, the smaller lashing connection part is clamped or held in a state equivalent to the holding or holding of the larger lashing connection part. As a result, the fixation on the roof is not sufficient, and the folded-plate roof power frame may be detached from the tightening connection portion due to the load or negative pressure of the installation object on the roof.

  In addition, depending on the state of the tightening connecting portion and the rod, there is a risk that when the first and second clamping members are combined, a C shape or an inverted C shape is obtained. In this case, there is a possibility that the folded-plate roof power frame cannot be mounted on the roof or cannot be mounted in a safe state.

  In the mounting bracket of FIG. 7, the pair of sandwiching pieces is formed of a metal plate without a reinforcing surface or the like. Therefore, there is a risk that the clamping piece may be deformed and dropped due to the tightening strength of the tightening means and the weight of the attached structure.

  Further, the placing piece and the sandwiching piece are combined by a locking hole and a hook piece. In the mounting bracket of FIG. 7, when the tightening means is tightened, a force is applied in a direction in which the hook piece is removed from the locking hole. Therefore, when it tightens too much, there exists a possibility that a hook piece may remove | deviate from a locking hole. On the other hand, if the tightening is too loose, the pair of sandwiching pieces becomes a C shape. As a result, the hook piece locked in the locking hole is easily detached by negative pressure. Furthermore, since the hook piece penetrates from the locking hole onto the mounting piece and locks, if the tightening is not in an optimum state, the bent part or end of the hook piece protrudes upward from the mounting piece. As a result, there was a risk of hindering construction and installation.

  Further, both the folded-plate roof power frame of FIG. 6 and the mounting bracket of FIG. 7 have a problem that it is difficult to adjust the height when the roof to be mounted is uneven.

  In this application, if it is a dimensional error and a construction error, it will be in a stable holding state regardless of the state of the tightening portion of the tile rod, and the holding state will not affect the installation of the installation on the roof, The purpose is to provide a mounting bracket that is not deformed by the weight of the upper installation object.

  Furthermore, it aims at providing the mounting bracket of the installation object on a roof provided with the height adjustment function in addition to the above.

  The mounting fixture for an installation on the roof of the present application is an installation fixture for an installation on the roof used for a roof having a tile rod, and includes a holding member, an attachment member, and a fastening tool.

  The holding member is composed of a left holding body and a right holding body. The left and right holding bodies have a connecting portion formed at the upper end, a side surface in which a through hole is formed, and a bent surface in which the side edge of the eaves ridge is bent inward. The bending surface has a holding portion.

  The attachment member has an upper surface, a side surface in which a through hole is formed, and a connected portion formed above the through hole.

  The left and right holding bodies are arranged to face each other on both sides of the mounting member, and the connecting portion and the connected portion that are fitted to each other are combined.

  In addition to the above features, the mounting bracket for an installation on the roof shown in claim 2 of the present application is characterized in that a lip groove is formed on the upper surface of the mounting member.

  In addition to the above-described features, the mounting bracket for an installation on a roof according to claim 3 of the present application has a left and right vertical surface provided with a plurality of height adjustment grooves on the opposite side above the upper surface of the mounting member. It is formed.

  The connected portion of the mounting member and the connecting portion of the holding member are in a shape that fits to each other, and can be combined to adjust the tightening degree of the both side tightening portions of the tile rod by the tightening tool. For this reason, it is possible to absorb some dimensional errors and construction errors of the roofing rod and to obtain an optimal installation state. At this time, since the left and right holding bodies are independent from each other, the holding state with respect to one of the tightening portions does not affect the other holding state.

  Since the holding member and the attachment member are separated from each other and the coupled portion is provided so as not to protrude upward from the upper surface by providing the coupled portion below the upper surface, the holding state of the holding member is It does not protrude above the top surface. As a result, the metal fitting of this application can attach an installation thing on a roof in the stable state.

  By forming the bent surface on the holding member, the strength against tightening by the tightening tool is increased, and deformation is difficult.

  Furthermore, a height adjustment function can also be added, so that height adjustment against unevenness can be easily performed.

  First, the Example of the mounting fixture of the installation object on a roof shown to Claim 1 and Claim 2 of this application is described with reference to FIGS.

  As shown in FIG. 1, the mounting bracket for the on-roof installation of the present application includes a holding member A, a mounting member B, and a fastening tool C.

  The holding member A is composed of a left holding body 1 and a right holding body 2. The left holding body 1 and the right holding body 2 are formed by bending the connecting portions 11 and 21 formed at the upper end, the side surfaces 12 and 22 formed with the through holes 121 and 221, and both side ends of the side surfaces 12 and 22 inward. It has the bent surface 13 * 23. The connecting portions 11 and 21 are combined with the connected portion 5 of the attachment member B. 1, the connecting portions 11 and 21 are formed at the upper ends of the bent surfaces 13 and 23, but may be formed at the upper ends of the side surfaces 12 and 22, and both the bent surfaces 13 and 23 and the side surfaces 12 and 22 may be formed. You may form in the upper end of. The bending surfaces 13 and 23 have holding portions 131 and 231.

  When the connecting portions 11 and 21 of the holding member A and the connected portion 5 of the attachment member B are fitted and the fastening tool C is tightened, the holding portions 131 and the left holding body 1 and the right holding body 2 are held. 231 are close to each other. On the other hand, when the fastening tool C is loosened, the holding parts 131 and 231 of the left holding body 1 and the right holding body 2 are opened, and can be attached to the roof bar G. The holding portions 131 and 231 have a shape that holds the clamping portions 91 and 91 of the brick rod G from the side and from below. In FIG. 1, the holding portions 131 and 231 are formed by cutting out in a substantially U-shape. However, the holding portions 131 and 231 may be any mechanism as long as they sandwich the side surface 4 of the attachment member B and the clamp portion 91 of the roofing rod G and are hooked on the side from below.

  The attachment member B has an upper surface 3 to which an installation object on the roof is attached, a connected portion 5, and a side surface 4 in which a through hole 41 is formed. In the present embodiment, the extruded attachment member B is described, but a folded plate may be used. Moreover, although it can also process by welding, the direction of an extrusion process or a folded-plate process requires less effort of metal fitting manufacture.

  The fastening tool C refers to a bolt, a nut, or the like. The fastening tool C is attached by using the through-holes 121, 221 and 41 of the holding member A and the attachment member B, and is used for fastening and fixing the mounting bracket of the installation object on the roof of the present application to the roof bar G.

  The left and right holding bodies 1 and 2 are arranged on both sides of the mounting member B so as to face each other, and the connected parts 5 and 5 of the left and right holding bodies 1 and 2 and the connecting parts 11 and 2 of the mounting member B are fitted. 21 is combined. And the fastening tool C is attached using the holding member A and the through-holes 121, 221 and 41 of the attachment member B. By doing so, the holding member A and the mounting member B are integrated, and when tightened, the holding portions 131 and 231 of the holding member A connect the side surface 4 of the mounting member B and the barb clamping portion 91 of the roof bar G. It is a structure that is sandwiched and caught from below. Therefore, the mounting bracket for the installation object on the roof of the present application does not hold the roof bar G itself between the left holding body 1 and the right holding body 2 and fix it on the roof. One of the features is to hold and fix it on the roof.

  Moreover, the attachment bracket of the installation object on a roof of this application is combined as a shape which the clamping member A and the attachment member B fit mutually. It is desirable that the fitting portion between the connecting portions 11 and 21 and the connected portion 5 has an arc shape. When the mounting bracket of the installation object on the roof of the present application is mounted on the roof, the holding member A functions as a rotation shaft, and the holding members A are in a letter-shaped or reverse shape on the roof bar G. It may be shaped like a letter, and if the hooks 91 and 91 of the tile rod G are sandwiched and hooked from below, an installation on the roof can be attached.

  In this embodiment, the connecting portions 11 and 21 are convex and the connected portion 5 is a concave shape. However, any combination of shapes can be fitted and rotated. Or what is necessary is just to be able to connect so that sliding is possible.

Even if the state of both the fastening portions 91 and 91 of the rod G is different by making the connecting portions of the left holding body 1 and the right holding body 2 independent of each other, the optimum holding is performed for each. It is because it can be in a state.

  A lip groove 31 may be formed on the upper surface 3 of the attachment member B as a means for attaching the installation object on the roof. For example, as shown in FIG. 1, an opening having a width about the bolt diameter and a width about the opposite dimension of the nut can be provided. The lip groove 31 is prevented from rotating when a nut is inserted. In that case, the bolt hole 32 penetrating downward from the lip groove 31 is provided, and a bolt for fixing the installation object on the roof can be inserted from above.

  In the present embodiment, an example in which a nut is inserted has been described. However, by applying this, it is also possible to insert a bolt head into the lip groove 31 instead of a nut and erect the bolt upward.

  Here, the Example of the rotation prevention member D which can be used for the mounting bracket of the installation thing on the roof of this application is demonstrated in FIG.

  The lip groove 31 may be used not for directly inserting a bolt head or a nut, but for inserting a dedicated locking member D for them. The anti-rotation member D has an anti-rotation portion 71 and a locking portion 72. The rotation preventing portion 71 has a shape in which a nut or bolt head fits, and has a mechanism that prevents the nut or bolt head from rotating.
