JP-A-2002-81765 (FIGS. 1 to 3)

According to the above-described conventional wiring rack support member, it is necessary to attach a mounting member for fixing the sheet member to the mounting base and a support member for supporting the piping rack on the mounting base at individual positions on the mounting base. .
However, in order to attach the mounting member and the support member to the mounting base, it is often carried out using a screw member or the like.In this case, if the screw member penetrates the waterproof layer of the mounting base, the waterproofness decreases, As a preventive measure, waterproofing is required for each mounting location.
That is, according to the conventional wiring rack support member, since the installation work of the mounting member and the support member requires much time and effort, there is a problem that the mounting work efficiency is easily lowered as a whole.

  Such a problem may occur not only when a sheet member and a wiring rack are newly installed on a mounting base, but also when, for example, repair work is performed.

  Accordingly, it is an object of the present invention to provide a wiring rack support member which can solve the above-mentioned problems and can be efficiently mounted on a mounting base.

The feature of the present invention is a mounting member for fixing the electrically wired sheet member to the mounting base, and a support member for supporting the wiring rack capable of storing the electrical wiring connected to the sheet member on the mounting base, The support member is supported on the mounting base via the mounting member, and the support member is mounted on the mounting member while holding the sheet member therebetween .

According to the present invention, since the support member is supported on the mounting base via the mounting member, it is not necessary to directly mount the support member on the mounting base.
That is, if only the mounting member is mounted on the mounting base, the mounting member will support the supporting member and the wiring rack supported by the supporting member, thereby reducing the number of mounting points on the mounting base. Can be.
As a result, the labor for mounting the wiring rack support member on the mounting base can be reduced, and the mounting operation can be performed efficiently.

Further, when a screw member is used to attach the wiring rack support member to the mounting base, the number of screw members to be installed can be reduced as compared with the conventional case, so that it is easy to maintain the waterproofness of the mounting base. Also, the generation of vibration, noise, and the like due to the installation of the screw member can be accommodated in a short time.
As a result, it becomes possible to proceed with the installation work of the wiring rack support member in a state in which environmental obstacles to the building where the wiring rack support member is to be installed are suppressed. The wiring rack support member can be installed on the mounting base while being used as usual.

Another feature of the present invention is a mounting member for fixing an electrically wired sheet member to a mounting base, and a supporting member for supporting the wiring rack capable of accommodating the electrical wiring connected to the sheet member on the mounting base. And the support member is supported by the mounting base via the mounting member, the mounting member is provided with a wrapping portion that wraps the edge of the sheet member, the support member, there is to being supported by the mounting member in a state of sandwiching the wrapping section.

  According to this configuration, since the wrapping portion of the mounting member wraps the edge of the sheet member, the wrapping portion can be firmly clamped by the support member from the outside, so that the frictional force between the wrapping portion and the sheet member is effective. Thus, the sheet member can be supported and mounted on the mounting base without applying a large load to the sheet member and in a firm state.

  In addition, since the support member is supported by the mounting member while holding the wrapping portion, the holding function member for supporting the sheet member on the wrapping portion and the mounting function for mounting the support member itself on the mounting member and supporting it on the mounting base. Both of the components can be used, and the cost can be reduced as the number of parts is reduced.

  In addition, since the mounting operation of the support member can be performed by an extremely simple operation of merely holding the support member in the wrapping portion that supports the edge portion of the sheet member, the wiring rack includes fixing the sheet member to the mounting base. The installation work of the entire support member can be efficiently performed.

Further, when the support member is removed, the sandwiching of the sheet member is released, so that not only the attachment of the sheet member to the mounting base but also the removal can be performed quickly and efficiently.
Therefore, it is possible to efficiently work on maintenance and repair of the sheet member and the wiring rack support member installed on the mounting base.

In the present invention, the support member includes a pair of holding pieces that can hold the wrapping portion,
Preferably, a connecting portion is provided for connecting the pair of holding pieces in a state in which the pair of holding pieces can be separated and moved in the holding direction.

According to this configuration, the pair of holding pieces can be moved far and near in the holding direction by the connecting portion, and accordingly, adjustment of the holding thickness and adjustment of the holding strength can be easily performed. .
Accordingly, the support member can be attached in a firmly sandwiched state even to sheet members and attachment members having different thicknesses, and the versatility of the entire wiring rack support member can be improved.

Embodiments of the present invention will be described below with reference to the drawings.
FIGS. 2 and 7 show a solar rack (an example of a sheet member) 2 on a mounting base 1 using an embodiment product (hereinafter simply referred to as a rack fixture F) of a wiring rack supporting member of the present invention. A situation is shown in which a wiring rack R that accommodates electric wiring (not shown) connected to the solar sheet 2 is fixed.

In this embodiment, the mounting base 1 includes a roof slab 1A made of reinforced concrete, and a waterproof layer 1B made of a synthetic resin (for example, vinyl chloride or the like) installed along the upper surface of the roof slab 1A. .
A solar sheet installation area S is set on the mounting base 1, and a plurality of solar sheets 2 are laid with a gap M therebetween so as to cover the area S.

The solar sheet 2 may be constituted by a known solar sheet. For example, a solar power generation cell made of amorphous silicon, microcrystalline silicon, or the like, and a surface protective layer are laminated on a flexible base sheet. Is an example.
The solar sheet 2 has a film shape as a whole, has appropriate flexibility, and has a flexible structure capable of following the surface shape of the mounting base 1.
Although not shown in the figure, output terminals, electric wiring to the battery, and the like are provided, and the extended portions of the electric wiring are arranged in the wiring rack R.

The wiring rack R is formed of a long channel member as shown in the figure, and is arranged along the edge of the solar sheet 2. That is, the wiring rack R is placed on the gap M between the adjacent solar sheets 2 (see FIGS. 1 and 2) or on the outer edge of the solar sheet 2 located at the most end side (see FIG. 7). Are located. Although not shown in the drawings, a cover member is attached to the wiring rack R.
Note that the wiring rack R is not limited to those described above, and other known wiring racks can be used.

  The rack fixture F includes a mounting member FA for fixing the solar sheet 2 to the mounting base 1, and a support member FB for supporting the wiring rack R to the mounting base 1 via the mounting member FA.

As shown in FIGS. 3 and 4, the mounting member FA is configured to be able to be fixed to the mounting base 1 while sandwiching the outer peripheral edge of the solar sheet 2.
The specific configuration of the mounting member FA includes the following two members.
That is, an edge member FAa which is formed of a soft material (for example, soft vinyl chloride or the like), is attachable to the mounting base 1, and can wrap the outer peripheral edge 2a of the solar sheet 2, and a metal material (for example, aluminum or the like). ), And can be fitted from the outer peripheral side of the solar sheet 2 to the edge member FAa enclosing the outer peripheral edge 2a of the solar sheet 2, and sandwich the solar sheet 2 from the front and back via the edge member FAa. And a clip member FAb.

The edge member FAa is integrally formed as an elongated member along the outer peripheral edge 2a of the solar sheet 2 (see FIG. 1).
The edge member FAa includes a pair of opposing pieces 3A and 3B facing the front and back surfaces of the solar sheet 2 (see FIG. 4), and a connecting part 3C that connects the base ends of the pair of opposing pieces 3A and 3B. And a fixing portion 4 for attaching the wrapping portion 3 to the mounting base 1.

In the space between the pair of opposing pieces 3A, 3B in the wrapping portion 3, the solar power is inserted in the direction from the distal end to the base end of the pair of opposing pieces 3A, 3B (see the arrow in FIG. 3). The outer peripheral edge 2a of the sheet 2 can be inserted.
The pair of opposed pieces 3A and 3B have different lengths along the insertion direction.
That is, the first opposing piece 3A farther from the mounting base 1 is formed to have a smaller length than the second opposing piece 3B closer to the mounting base 1. With this structure, the resistance at the time of inserting the solar sheet 2 is reduced, so that the solar sheet 2 can be easily inserted. Further, the supporting area in the inserted state can be increased, and a stable supporting state can be maintained.

  The first opposing piece portion 3A includes a flat portion 3Aa having a constant (or substantially constant) thickness, and a protruding portion 3Ab protruding toward the second opposing piece portion 3B on the distal end side. That is, the first opposing piece 3A is formed so that the tip end side where the protruding portion 3Ab is provided is thicker than the flat portion 3Aa on the base end side. Therefore, by fitting the clip member FAb on the outer peripheral side of the wrapping portion 3, the protruding portion 3Ab is pressed against the surface of the solar sheet 2 and exerts a clamping action with the second opposing piece 3 </ b> B to exert the action of clamping the solar sheet 2. Can be prevented (see FIG. 4).

The distance between the opposing portions of the first opposing piece 3A and the second opposing piece 3B is closer to the base end side having the flat portion 3Aa than to the tip end side where the protruding portion 3Ab is provided. It is formed large, and the inner peripheral portion of the flat portion 3Aa is a concave portion.
The concave portion is filled with an adhesive material 5 (for example, butyl rubber or the like).
Therefore, when the adhesive 5 comes into contact with the outer peripheral edge 2a of the solar sheet 2 inserted between the pair of opposing pieces 3A, 3B, the solar sheet 2 can be more difficult to come out.

  In addition, since the concave portion is formed in the inner peripheral portion of the flat portion 3Aa in the first opposed piece portion 3A, when the clip member FAb is fitted to the wrapping portion 3 (see the arrow in FIG. 4), the flat portion 3Aa is formed. It is possible to temporarily retreat to the concave portion side, and it is possible to reduce the resistance and smoothly fit.

  The fixing portion 4 is integrally provided at the distal end of the second opposing piece 3B so as to be folded back toward the base end. Therefore, the second opposing piece 3B is located in a state of overlapping with the fixing part 4. A gap between the second opposing piece 3B and the fixing part 4 is an insertion part into which the second holding piece 6B on the mounting base 1 side of the pair of holding pieces 6A, 6B of the clip member FAb can be inserted. It is 7.

The fixing portion 4 is configured to be fixed to the upper surface of the waterproof layer 1B by bonding.
The fixing portion 4 includes an extending portion 4A extending to the distal end of the second opposing piece 3B, and a folded portion 4B that folds from the extending portion 4A below the second opposing piece 3B.

  The extended portion 4A has an upper surface formed as an inclined surface closer to the mounting base 1 as the distance from the second opposing piece 3B increases. Since the solar sheet 2 can be supported by the inclined surface, it is possible to prevent the solar sheet 2 from being sharply bent near the insertion portion 7.

  The folded portion 4B is formed with a concave groove 4Ba along the longitudinal direction of the edge member FAa at a boundary portion with the extending portion 4A so that a retaining projection 8 of a clip member FAb described later can be fitted therein. I have.

  The clip member FAb includes a first holding piece 6A that abuts on the upper surface of the first facing piece 3A and a second holding piece 6B that abuts on the lower face of the second facing piece 3B when fitted to the wrapping portion 3. And a member having a U-shaped cross section. Further, in the embodiment, the clip member FAb is formed as a short member to be installed locally at a longitudinal direction of the edge member FAa (a direction along the outer peripheral edge 2a of the solar sheet 2). By using a short member, the resistance at the time of attaching and detaching to and from the edge member FAa can be reduced, and the attaching and detaching operation can be performed more smoothly. Also, as shown in FIG. 1, the clip members FAb are installed at a plurality of locations spaced apart in the longitudinal direction of the edge member FAa.

Like the pair of opposing pieces 3A, 3B, the pair of holding pieces 6A, 6B have different lengths along the fitting direction (see FIG. 4).
That is, the first holding piece 6A farther from the mounting base 1 is formed to have a smaller length than the second holding piece 6B closer to the mounting base 1.

Each of the holding pieces 6A and 6B has a retaining projection 8 at the tip end thereof, which protrudes downward and intersects the fitting direction.
The retaining projection 8A of the first holding piece 6A comes into contact with the distal end surface of the first opposing piece 3A to exhibit a retaining effect.
The retaining protrusion 8B of the second holding piece portion 6B exerts a retaining effect by being fitted into the concave groove 4Ba of the folded portion 4B.

  As shown in FIGS. 5 to 7, the support member FB is formed of a metal material (for example, aluminum or the like), and is capable of holding the wrapping portion 3 of the mounting member FA from outside the clip member FAb. 9), and a screw member (corresponding to a connecting portion) N for connecting the pair of holding members 9 so as to be able to be separated and moved in the holding direction. The support member FB is supported by the mounting member FA in a state where the wrapping portion 3 is held between the pair of holding members 9.

The screw member N is composed of a bolt NA installed in an inverted state in which the enlarged diameter head NAa is located on the lower end side, and a nut NB that can be screwed from the upper end of the bolt NA to the shaft portion NAb.
The screw member N has a function of connecting the wiring rack R and the holding member 9 in addition to the function of holding and connecting the pair of holding members 9.

The pair of holding members 9 are formed so that the dimension along the longitudinal direction of the wiring rack R is the same length as the clip member FAb, and a top member (holding piece) that is disposed in contact with the clip member FAb. 9A) and a base member (corresponding to a holding piece) 9B which is inserted into the insertion portion 7 of the edge member FAa and holds the mounting member FA with the top member 9A.
The sandwiching member 9 is installed in the gap M between the adjacent solar sheets 2 (see FIG. 2) and the sandwiching member 9 is installed at the outer edge of the solar sheet 2 located at the most end side (FIG. 7). ), The number of mounting members FA to be clamped is different, and therefore, their shapes are also different.

The top member 9A has an upper surface portion 9Aa on a flat plate on which the wiring rack R is placed and supported, a vertical surface portion 9Ab bent downward from an end of the upper surface portion 9Aa, and a bent surface bent inward from a lower end portion of the vertical surface portion 9Ab. A portion 9Ac and an inner vertical surface portion 9Ad bent downward from the inner end of the bent portion 9Ac.
As for the holding member 9 installed in the gap M between the adjacent solar sheets 2, the top member 9A has a symmetrical cross section across the center in the width direction of the upper surface 9Aa as shown in FIG. It is formed in a shape, and has a vertical surface portion 9Ab, a bent portion 9Ac, and an inner vertical surface portion 9Ad on both sides of the central portion in the width direction of the upper surface portion 9Aa.

  In addition, as for the sandwiching member 9 arranged at the outer edge of the solar sheet 2 located at the end side, the top member 9A sandwiches the center in the width direction of the upper surface 9Aa as shown in FIG. Only one side has a vertical surface portion 9Ab, a bent portion 9Ac, and an inner vertical surface portion 9Ad, and the other side has the vertical surface portion 9Ab extended to the lower end.

  As shown in FIGS. 2 and 7, a bolt hole H1 through which the shaft portion NAb of the bolt NA can be inserted is formed in the upper surface portion 9Aa, and the bolt hole H1 and a wiring placed on the upper surface portion 9Aa are formed. The screw member N can be inserted through the bolt hole H2 of the rack R to achieve integration.

  The bent portion 9Ac is formed to have the same width as the first holding piece 6A of the clip member FAb, and the bending portion 9Ac is formed on the upper surface of the first holding piece 6A with the holding operation of the holding member 9. The lower surface of the abutment can transmit the pressing force.

The vertical length of the inner vertical surface portion 9Ad is set slightly smaller than the vertical length of the clip member FAb, and the screw member N is tightened between the lower end portion of the inner vertical surface portion 9Ad and the upper surface of the base member 9B. A gap K as a substitute is secured (see FIGS. 6 and 7). With this configuration, the screw member N can be prevented from being overtightened.
In addition, as for the holding member 9 arranged at the outer edge of the solar sheet 2 located at the most end side, the lower end of one vertically extending portion 9Ab extended downward is the lower end of the other inner longitudinal surface 9Ad. It is formed longer by the dimension corresponding to the gap K (see FIG. 7).

The base member 9B has, at the left and right intermediate portions, a recessed bent portion 9Ba for accommodating the enlarged diameter head NAa of the bolt NA, and extended portions 9Bb extending to both sides of the recessed bent portion 9Ba. .
The recessed bent portion 9Ba has a bolt hole H3 through which the shaft portion NAb of the inverted bolt NA can be inserted.
The extension portion 9Bb is installed in the insertion portion 7 so as to overlap the lower side of the second holding piece portion 6B of the clip member FAb.
In this embodiment, the enlarged diameter head NAa of the bolt NA is formed in a hexagonal shape, and the outer peripheral surface of the enlarged diameter head NAa abuts on the opposing side wall in the concavely bent portion 9Ba. Can be used to prevent rotation.

Next, a procedure for installing the solar sheet 2 and the wiring rack R on the mounting base 1 will be described.
[1] The edge member FAa is joined to a predetermined position of the mounting base 1, and the outer peripheral edge 2a of the solar sheet 2 is inserted between the first facing piece 3A and the second facing piece 3B of the wrapping portion 3. Then, the clip member FAb is fitted to the wrapping portion 3 to hold the solar sheet 2 (see FIGS. 3 and 4).

[2] The base member 9B is arranged in the insertion portion 7 of the edge member FAa (see FIG. 5).
At this time, the bolt NA is provided in an inverted state in which the enlarged diameter head NAa is located at the concave bent portion 9Ba and the shaft portion NAb passes through the bolt hole H3.

[3] The top member 9A is arranged from above the base member 9B, and the mounting member FA is sandwiched from above and below (see FIGS. 5 and 6).
At this time, the top member 9A is positioned so that the upper end of the bolt NA passes through the bolt hole H1 of the top member 9A.

[4] The wiring rack R is arranged along the upper surface 9Aa of the top member 9A.
At this time, the wiring rack R is positioned so that the upper end of the bolt NA passes through the bolt hole H2 of the wiring rack R.

[5] Attach the nut NB to the upper end of the bolt NA and tighten it (see FIGS. 2 and 7).
At this time, the nut NB can adjust the tightening strength so that the solar sheet 2 and the mounting member FA can be clamped with an appropriate clamping force.
With the above procedure, the wiring rack R can be supported by the mounting base 1.

According to the rack fixture F of this embodiment, since the support member FB is supported by the mounting base 1 via the mounting member FA, there is no need to directly attach the support member FB to the mounting base 1. The time and effort required to attach the support member FB and the wiring rack R to the wiring rack R can be reduced, and the attaching operation can be performed efficiently.
In addition, since not only the attachment to the attachment base 1 but also the removal thereof can be carried out quickly and efficiently, a sufficient effect can be expected for the repair work of the solar sheet 2 and the wiring rack R.

  Further, since the support member FB is supported by the mounting member FA while sandwiching the wrapping portion 3, the holding member FB itself supporting the solar sheet 2 by the wrapping portion 3 and the support member FB itself are attached to the mounting member FA. Both the mounting function member supported by the mounting base 1 can be shared, and the cost can be reduced as the number of parts is reduced.

Further, since the wiring racks R are installed by effectively utilizing the gap M between the adjacent solar sheets 2, the space is effectively utilized, and both solar racks adjacent by one wiring rack R are used. Since the electric wiring of the sheet 2 can be accommodated collectively, more space can be saved.
In addition, since the supporting member FB installed on the gap M is supported by the mounting base 1 on both sides of the screw member N, the supporting member FB can be installed in a stable posture, and furthermore, the resistance to floating and the like is also reduced. Can be expected.
