Description

  The present invention relates to a sheet member fixture for attaching a sheet member such as a solar sheet to an attachment base such as a roof.

  Conventionally, as this type of sheet member fixture, a bolt or an adhesive is used to mount a sheet member (a solar sheet in the form of a film) along a mounting base (a roof made of a panel material). Has been used as a fixture (for example, see Patent Document 1).

JP 2011-18459 A (see paragraph number [0089], FIG. 1)

According to the above-described conventional sheet member fixing tool, in the case of fixing with a bolt, the bolt (or female screw member) is fixed to the mounting base in advance, and a bolt insertion hole is formed in the sheet member, There is a method in which a sheet member is set so that the bolt passes through the bolt insertion hole, and a fixing member is screwed to the bolt and fixed. However, in this bolt fixing, since the sheet member is held in a state that does not shift due to the fitting between the bolt and the bolt insertion hole, when an external force (for example, lift by wind) acts on the sheet member, Stress concentration tends to occur around the bolt insertion hole. That is, there is a problem that the stress load on the sheet member tends to be large, and in the worst case, there is a concern that the sheet member may be torn from around the bolt insertion hole.
In addition, in the case of fixing with an adhesive, in a sheet member that is often covered with a fluororesin coating like a solar sheet, it is extremely difficult to bond, and it takes a lot of labor and cost for the bonding work, and the sheet member There is a problem that the fixed work efficiency is poor.

  Accordingly, an object of the present invention is to provide a sheet member fixing tool that can solve the above-described problems, can be fixed in a state where the stress load on the sheet member is small, and can efficiently perform the fixing operation of the sheet member. .

A feature of the present invention is that the outer peripheral edge of a sheet member installed in a state of covering the mounting base is freely wrapping, and a wrapping part having flexibility,
An attachment part for attaching the enveloping part to the attachment base;
And a clamping member that is attached to the wrapping part in a state of wrapping the outer peripheral edge part and clamps the sheet member via the wrapping part.

According to the present invention, since the outer peripheral edge of the sheet member is softly wrapped by the soft wrapping portion, the wrapping portion can be firmly clamped by the clamping member from the outside, so that the bolt of the sheet member can be secured as in the prior art. It is possible to avoid the occurrence of stress concentration around the insertion hole.
That is, the sheet member can be attached to the attachment base without being subjected to a large load and in a state of being firmly supported.

  In addition, the fixing operation of the sheet member can be performed by an extremely simple operation of wrapping the sheet member with the wrapping portion attached to the mounting base at the mounting portion, and holding them with the clamping member. It becomes possible to fix to the ground efficiently.

Moreover, since the nipping of the sheet member is released when the nipping member is removed, not only the attachment of the sheet member to the attachment base but also the removal can be performed quickly and efficiently.
Therefore, when performing maintenance or repair of the sheet member fixed to the mounting base, it is easy to attach and detach the sheet member, and the work can be efficiently performed.

In the present invention, the wrapping portion includes a pair of opposing piece portions that respectively oppose the front and back surfaces of the sheet member, and a connecting portion that connects the base end portions of the pair of opposing piece portions,
It is preferable that the interval between the base end portions of the pair of opposed piece portions is larger than the interval between the distal end portions of the pair of opposed piece portions.

  According to this configuration, when the sheet member is sandwiched between the pair of opposed piece portions, the tip portions having a narrow interval are pressed against the front and back surfaces of the sheet member. As a result, the contact pressure on the sheet member at the tip of the opposed piece increases, and the sheet member can be prevented from coming off.

In addition, since both the base end portions of the pair of opposed piece portions have a larger interval than the distal end portions, a gap is easily formed between the front and back surfaces of the sheet member and the opposed piece portion.
Therefore, when the clamping member is attached / detached from the outside of the pair of opposing piece portions, the opposing piece portion (base end portion) pushed by the clamping member can be temporarily retracted in the gap. As a result, the resistance at the time of attaching and detaching the holding member can be reduced and smoothly attached and detached.

  In the present invention, it is preferable that an adhesive is provided in a space formed between the base end portions of the pair of opposed piece portions.

According to this configuration, by positioning the sheet member between the pair of opposed piece portions, the adhesive material can contact the sheet member to exert an adhesive force, and the sheet member can be prevented from coming off.
Further, since the adhesive material is covered with the opposing piece portion, the adhesive material is hardly affected by the adverse effect (deterioration due to wind and rain, ultraviolet rays, etc.) from the surrounding environment, and can prevent the sheet member from slipping out over a long period of time.

In the present invention, the enveloping part is provided in a state overlapping with the attachment part in the thickness direction view of the sheet member,
It is preferable that an insertion portion is provided between the wrapping portion and the attachment portion so that the attachment piece on the attachment base side of the pair of holding pieces of the holding member can be inserted.

  According to this configuration, since the wrapping portion and the attachment portion overlap as described above, the width dimension of the sheet member fixture (dimension along the insertion direction to the insertion portion in the thickness direction of the sheet member) Can be reduced, and space can be saved.

Further, in a state where the clamping member is attached to the wrapping portion, the clamping piece portion on the attachment base side is inserted into the insertion portion, so that it is not exposed to the outside, and a clean appearance can be formed as a sheet member fixture.
Furthermore, in the state where the clamping piece portion on the attachment base side is inserted into the insertion portion, the attachment piece is interposed between the clamping piece portion and the attachment base, so the clamping piece portion directly contacts the attachment base. Can be prevented. Therefore, for example, even when the sheet member vibrates due to the influence of wind or the like, the sandwiching piece portion and the mounting base do not come into contact with each other to generate noise.

In the present invention, the clamping piece portion on the mounting base side is provided with a retaining projection protruding to the mounting base side,
It is preferable that a retaining recess that allows the retaining projection to be freely inserted is provided at a position corresponding to the retaining projection in the insertion portion.

According to this configuration, the retaining protrusion can be engaged with the retaining recess as the clamping base portion on the mounting base side is inserted into the insertion portion, and the sandwiching piece portion is engaged by the engagement between the protrusion and the recess. Can be prevented from coming out.
Therefore, the attachment state of the clamping member with respect to the wrapping portion can be maintained.

  Further, since the retaining recess is formed by recessing a part of the mounting portion located below the insertion portion, the thickness at the recess forming portion is thinner than other portions. However, since the attachment portion itself is attached to the attachment base as a whole, the effect of reinforcement by the attachment base can be expected, the adverse effects due to the thin wall are reduced, and the clamping member can be stably locked.

  As a comparative example, if the protrusion direction of the retaining protrusion protrudes to the opposite side of the mounting base, for example, in this case, the retaining recess is a part of the opposing piece located above the insertion part. It will be recessed. As a result, the recessed portion may become thin and it may not be possible to secure the strength for locking the retaining protrusion. Further, if the entire opposing piece is formed thick in order to solve this problem, the entire sheet member fixture may be bulky and the cost may be increased.

Embodiments of the present invention will be described below with reference to the drawings.
1 and 6 show an embodiment of the sheet member fixture of the present invention (hereinafter simply referred to as a sheet fixture F), and a solar sheet (an example of a sheet member) 2 is fixed on the mounting base 1. The situation that is being shown.

In the 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) installed along the upper surface of the roof slab 1A. .
A solar sheet installation area S is set on the mounting base 1, and the solar sheet 2 is installed in a state of covering the area S.

The solar sheet 2 may be composed of a known solar sheet. For example, a solar power generation cell made of amorphous silicon or microcrystalline silicon and a surface protective layer are laminated on a flexible base sheet. Is given as an example.
The solar sheet 2 has a film shape as a whole, has an appropriate flexibility, and has a flexible structure capable of following the surface shape of the mounting base 1.
Although not shown in the figure, it goes without saying that output terminals, wiring to the battery, and the like are provided.

The sheet fixture F is configured so that it can be fixed to the mounting base 1 while sandwiching the outer peripheral edge of the solar sheet 2.
The specific structure of the sheet fixture F includes the following two members.
That is, an edge member Fa that is formed of a soft material (for example, soft vinyl chloride), can be attached to the mounting base 1, and can wrap around the outer peripheral edge 2a of the solar sheet 2, and a metal material (for example, aluminum) Is sandwiched between the outer periphery of the solar sheet 2 and the solar sheet 2 is sandwiched from the front and back via the edge member Fa. And a member Fb.

The edge member Fa is integrally formed as an elongated long member along the outer peripheral edge 2a of the solar sheet 2 (see FIG. 1).
The edge member Fa includes a pair of facing piece portions 3A and 3B that face the front and back surfaces of the solar sheet 2 (see FIG. 6), and a connecting portion 3C that connects base ends of the pair of facing piece portions 3A and 3B. And an attachment portion 4 for attaching the envelope portion 3 to the attachment base 1 is provided.

In the space between the pair of opposed piece portions 3A and 3B in the enveloping portion 3, solar is inserted in the insertion direction from the distal end side to the proximal end side of the pair of opposed piece portions 3A and 3B (see the arrow in FIG. 2). The outer peripheral edge 2a of the sheet 2 can be inserted.
The pair of opposing piece portions 3A and 3B have different lengths along the insertion direction.
That is, the length of the first opposing piece 3 </ b> A far from the mounting base 1 is smaller than that of the second opposing piece 3 </ b> B closer to the mounting base 1. With this structure, the resistance when the solar sheet 2 is inserted becomes smaller and easier to insert, and the support area in the inserted state can be increased and a stable support state can be maintained.

  The first opposing piece portion 3A includes a flat portion 3Aa having a constant thickness (or substantially constant) and a protruding portion 3Ab that protrudes toward the second opposing piece portion 3B on the tip side. That is, the first opposing piece portion 3A is formed such that the distal end portion side where the protruding portion 3Ab is provided is thicker than the flat portion 3Aa on the proximal end portion side. Therefore, by fitting the clamping member Fb on the outer peripheral side of the wrapping part 3, the protruding part 3Ab presses against the surface of the solar sheet 2 and exhibits a clamping action with the second opposing piece part 3B. 2 can be prevented from coming out.

In addition, the distance between the opposing portions of the first opposing piece portion 3A and the second opposing piece portion 3B is larger on the proximal end side including the flat portion 3Aa than on the distal end side where the protruding portion 3Ab is provided. The inner periphery of the flat portion 3Aa is a recess.
This concave portion is filled with an adhesive material 5 (for example, butyl rubber or the like).
Therefore, the adhesive material 5 comes into contact with the outer peripheral edge 2a of the solar sheet 2 inserted between the pair of opposed pieces 3A and 3B, so that it can be more difficult to come out.

  Moreover, since the recessed part is formed in the inner peripheral part of flat part 3Aa in the 1st opposing piece part 3A, when fitting the clamping member Fb in the enveloping part 3 as shown in FIG. 5 (arrow in a figure) The flat portion 3Aa can be temporarily retracted to the concave portion side, and the resistance can be reduced and the flat portion 3Aa can be smoothly fitted.

  The second opposing piece 3B is integrally provided with the mounting portion 4 at the distal end thereof so as to be folded back toward the proximal end. Accordingly, the second facing piece 3B is positioned so as to overlap the mounting portion 4. The gap between the second facing piece 3B and the mounting portion 4 is an insertion portion in which the second holding piece 6B on the mounting base 1 side of the pair of holding pieces 6A, 6B of the holding member Fb can be inserted. 7 (see FIGS. 3 and 4).

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

  The extending portion 4A has an upper surface formed as an inclined surface that is closer to the mounting base 1 as the distance from the second opposing piece portion 3B increases. Since the solar sheet 2 can be supported by the inclined surface, the solar sheet 2 can be prevented from being bent suddenly in the vicinity of the insertion portion 7.

  In the folded portion 4B, a groove 4Ba (an example of a retaining recess) along the longitudinal direction of the edge member Fa is formed at a boundary portion with the extending portion 4A, and a retaining projection 8 of the clamping member Fb described later is formed. It is configured so that it can be inserted.

  The sandwiching member Fb has a first sandwiching piece portion 6A that contacts the upper surface of the first opposing piece portion 3A and a second sandwiching piece portion 6B that contacts the lower surface of the second opposing piece portion 3B in a state of being fitted to the wrapping portion 3. It is comprised with the member of the cross-section "U" character shape provided with these. Moreover, in the said embodiment, the clamping member Fb is formed as a short member installed in the local part in the longitudinal direction (direction along the outer periphery 2a of the solar sheet 2) of the edge member Fa. By setting it as a short member, the resistance at the time of attachment / detachment to the edge member Fa can be reduced, and the attachment / detachment operation can be performed more smoothly. Further, as shown in FIG. 1, the clamping member Fb is installed at a plurality of locations spaced in the longitudinal direction of the edge member Fa.

The pair of sandwiching pieces 6A and 6B have different lengths along the fitting direction (see FIG. 5), similarly to the pair of facing pieces 3A and 3B.
That is, the length of the first clamping piece 6 </ b> A far from the mounting base 1 is smaller than the length of the second clamping piece 6 </ b> B closer to the mounting base 1.

Each of the sandwiching piece portions 6A and 6B is provided with a retaining protrusion 8 that protrudes in the downward direction intersecting the fitting direction at the tip portion.
The retaining protrusion 8A of the first sandwiching piece portion 6A abuts on the tip surface of the first opposing piece portion 3A and exhibits a retaining effect.
The retaining protrusion 8B of the second clamping piece 6B exhibits a retaining effect by being fitted into the recessed groove 4Ba of the folded portion 4B.

A procedure for fixing the solar sheet 2 to the mounting base 1 will be described.
[1] The edge member Fa is joined to a predetermined position of the mounting base 1 (see FIG. 2).
[2] The outer peripheral edge 2a of the solar sheet 2 is inserted between the first opposed piece 3A and the second opposed piece 3B of the wrapping portion 3 (see FIGS. 2 and 3).
[3] The clamping member Fb is fitted into the wrapping portion 3 (see FIGS. 4 and 5).
[4] The retaining protrusion 8A is engaged with the tip of the first opposing piece 3A, and the retaining protrusion 8B is fitted into the recessed groove 4Ba of the folded portion 4B, thereby completing the attachment of the holding member Fb ( (See FIG. 6).

According to the sheet fixing tool F of this embodiment, the solar sheet 2 can be fixed to the mounting base 1 in a state where the solar sheet 2 is firmly supported by the wrapping portion 3 without applying a large load to the outer peripheral edge portion 2a. .
Moreover, since the fixing operation | work and removal operation | work of the solar sheet 2 can be implemented by the very simple operation which only attaches / detaches the clamping member Fb to the enveloping part 3, the efficiency of those operations can be improved.
