Description

The present invention relates to a setting jig of the underlying frames of the solar panels.

  Solar panels such as solar power generation panels and solar hot water supply panels are often installed on the roof. When installing the solar panel on the roof, the solar panel is placed on a base frame laid on the roof and fixed by a fixing means such as a screw (for example, see Patent Document 1). ). In order to install a base frame, positioning is performed by taking out the distance between adjacent base frames by inking.

JP 2000-96793 A (FIG. 8)

  By the way, since a solar panel is installed on a sunny roof or the like, it is thermally expanded by the heat of sunlight. Therefore, the distance between the base frames is a dimension obtained by adding the deformation length due to thermal expansion to the panel size. Specifically, for example, in a solar panel having a general size of about 1200 mm × 1000 mm, the clearance for accommodating thermal expansion is defined as about 2 mm. However, in the conventional method of determining the installation position of the base frame by inking, the accuracy depends on the skill level of the craftsman, and there are problems that errors occur in dimensions and parallelism, and the work is complicated. there were. Furthermore, when installing solar panels on the roofs of wooden houses, there are no quality problems such as waterproofing depending on the construction material (wood), construction method, and work environment of the roof base material. Since unevenness or undulation may occur on the surface, there is a problem that it is difficult to position the base frame in units of mm by inking.

The present invention has been made to solve the above problems, to provide a setting jig of the underlying frames of the solar panel can be positioned high base frame accurate easy task This is the issue.

The present invention for solving the above problems is a first member having a certain length in an installation jig for installing a plurality of base frames on which a solar panel is placed and fixed at a desired interval. And a second member having a length appropriately set according to the size of the solar panel to be installed, the first member has a rectangular frame shape in plan view, and the second member Presents a U-shape in plan view formed by standing up square pipes at both ends of the angle member, and the tip of the square pipe of the second member is fixed to the short side of the first member, The short side of the first member located on the opposite side of the second member constitutes a first abutting portion that abuts one of the already installed base frames, and the angle member of the second member is newly the second contact portion constitutes a, the first member abutting on the other of the base frame to be installed in A pair of short sides, is placed jig base frame of the solar panel, characterized in that the gripping bar for gripping is bridged when moving the installation jig.

According to such a structure, an installation jig having a desired separation dimension set in advance according to the size of the solar panel is brought into contact with one base frame as a spacer, and the position of the other base frame is determined. Since it can be determined, highly accurate positioning can be performed. In addition, since ink marking is not performed, the work is easy and the accuracy is not affected by the skill level of the craftsman. Furthermore, since the first contact portion and the second contact portion are configured to be parallel to each other with a certain length, it is possible to ensure parallel accuracy between the existing base frame and the newly installed base frame. it can.

  Embodiments of the present invention will be described in detail with reference to the drawings. In this embodiment, a case where a solar panel is installed on a sloped roof will be described as an example.

  As shown in FIG. 1, a plurality of solar panels P are arranged along the gradient direction X of the roof R and the orthogonal direction Y perpendicular to the gradient direction X along the roof surface. The solar panel P has a rectangular shape, and is arranged sideways so that the longitudinal direction is along the orthogonal direction Y. In addition, although the solar panel P of this embodiment has illustrated the solar power generation panel provided with the solar power generation cell 3 (refer FIG. 2) on the surface, it is not the meaning limited to this, The thermal energy of sunlight It is good also as a solar hot water supply panel which obtains hot water in, and it is good also as a hybrid solar panel which has the function of a solar power generation panel and a solar hot water supply panel. The solar panel P is fixed on a base frame 30 (see FIGS. 2 and 5) laid on the roof R. Between the solar panels P, P adjacent to each other in the gradient direction X or the orthogonal direction Y, a joint 2 (see FIG. 7) having a predetermined width is formed. A joint water-stopping member 1 is attached to the joint 2.

  First, the installation structure of the solar panel P will be described. As shown in FIG. 2, the solar panel P is fixed on the base frame 30 fixed on the support block 43 disposed on the surface material 41 of the roof R. The base frame 30 is disposed extending along the orthogonal direction Y (see FIG. 5). Under the both longitudinal ends of the base frame 30, support blocks 43 are respectively arranged. The base frame 30 is formed by bending a plate made of aluminum or stainless steel, and has a target shape centering on an intermediate portion in the width direction. A protrusion 31 that protrudes upward is formed at an intermediate portion in the width direction of the base frame 30. Bolt holes 31a (see partially enlarged views of FIGS. 2 and 5) for fixing the joint water-stopping member 1 are formed on the upper surface of the protrusion 31. The bolt holes 31a are long holes extending in the longitudinal direction of the base frame 30 and are formed at both ends in the longitudinal direction of the base frame 30 (see the partially enlarged view of FIG. 5). On both sides of the ridge 31, support portions 32, 32 are formed which extend to both ends in the width direction and support the solar panel P from below. The solar panel P is placed with the bottom surface of the edge portion Pa in contact with the upper surface of the support portion 32. A groove portion 33 is formed in the support portion 32, and the bottom surface of the groove portion 33 comes into contact with the support block 43 and the base frame 30 is placed thereon. The groove 33 serves as a reinforcing rib. A screw hole 33 a for fixing the base frame 30 to the roof R is formed on the bottom surface of the groove 33. A screw 34 is inserted into the screw hole 33a from above. The screw 34 penetrates the surface material 41 of the roof R, and its tip is screwed to a roof base material 44 such as a rafter.

  The joint water-stopping member 1 is a member that stops the joint 2 and includes a cover member 10 that covers the joint 2 and an elastic sealing material 20 that is interposed between the cover member 10 and the solar panel P. I have. The cover member 10 is made of a plate material made of aluminum or stainless steel. The cover member 10 includes a surface portion 11 and an insertion portion 12. The cover member 10 may be formed by joining the insertion portion 12 to the surface portion 11 or may be integrally formed with an extruded profile. Further, it may be formed by bending one plate.

  The surface portion 11 extends along the joint 2 and is formed in a plate shape. Both ends in the width direction of the surface portion 11 cover the surfaces of the edge portions Pa and Pa of the solar panels P and P on both sides of the joint 2 together with the joint 2. Bolt holes 13 for fixing the joint water-stopping member 1 to the base frame 30 are formed in the surface portion 11. The bolt holes 13 are located at the intermediate portion in the width direction of the surface portion 11 and are formed at both ends in the longitudinal direction of the surface portion 11.

  The insertion portion 12 is a portion that protrudes from the back surface of the front surface portion 11 and is inserted into the joint 2. The insertion portion 12 is composed of a pair of plates orthogonal to the back surface, and an outer side surface thereof (a surface facing the side surface of the edge portion Pa of the solar panel P) is spaced from the solar panel P. It is configured. The space | interval of the solar panel P and the insertion part 12 is a dimension by which the elastic sealing material 20 is compressed by moderate stress.

  The elastic sealing material 20 is made of rubber or resin having elasticity, and extends along the longitudinal direction of the cover member 10. The elastic sealing material 20 is in contact with both the back surface of the front surface portion 11 and the side surface of the insertion portion 12 of the cover member 10 and is fixed by an adhesive. The elastic sealing material 20 is pressed by the surface and side surfaces of the edge portion Pa of the solar panel P in a state where the joint water-stopping member 1 is mounted on the joint 2. Thereby, the elastic sealing material 20 forms two sealing surfaces, that is, a sealing surface formed in contact with the surface of the edge portion Pa of the solar panel P and a sealing surface formed in contact with the side surface. Become.

  Next, the configuration of the installation jig 50 according to the present embodiment will be described with reference to FIGS. 3 and 4. The installation jig 50 is for installing the base frame 30 at a desired interval (see FIG. 5). As shown in FIGS. 3 and 4, the installation jig 50 includes a first member 51 having a certain length and a second member having a length appropriately set according to the dimensions of the solar panel P to be installed. 55 is connected.

  The first member 51 is formed by combining angle members 52, 52,... Having an L-shaped cross section into a rectangle by welding. A first abutting portion 53 with which the outer front end surface of the horizontal portion 52 a of the angle member 52 located on one short side abuts the base frame 30 is configured. A screw through-hole 54 (see FIG. 4) for fixing the second member 55 is formed in the rising portion 52b of the angle member 52 located on the other short side. The screw through holes 54 are formed at both ends of the angle member 52 in the longitudinal direction. A gripping rod 62 is bridged between a pair of angle members 52, 52 constituting the short side. The gripping rod 62 is a portion that is gripped when the installation jig 50 is moved, and is welded to the intermediate portion of the short side. The gripping rod 62 has a U-shaped cross section, but is not limited to this shape.

  The second member 55 is formed by joining a square pipe 57 to the angle member 56 by welding. The square pipe 57 is erected on rising portions 56a at both ends in the longitudinal direction of the angle member 56, and a cover plate 59 (see FIG. 4) having a screw hole 58 (see FIG. 4) formed at the tip is welded. It is fixed. The second member 55 is detachably fixed to the first member 51 by a screw 60 with the cover plate 59 at the tip of the square pipe 57 abutting against the rising portion 52 b of the angle member 52 of the first member 51. Accordingly, the corner portion of the angle member 56 is positioned on the side opposite to the first contact portion 53, and the corner portion constitutes a second contact portion 61 that contacts the base frame 30. The second contact portion 61 has a length equivalent to that of the first contact portion 53. The first contact portion 53 and the second contact portion 61 are parallel to each other. The distance between the first contact portion 53 and the second contact portion 61 is the length of the installation jig 50. The second member 55 is formed of a plurality of lengths of the second member 55 by using the square pipes 57 having different lengths (see the inside of the imaginary line square frame in FIG. 4). That is, the first member 51 has a fixed length, and the length of the installation jig 50 is adjusted by changing the second member 55 having a different length.

  The length of the installation jig 50 in which the first member 51 and the second member 55 are combined is a length obtained by adding the size of the solar panel P and a change size due to thermal expansion of the solar panel P. Specifically, it is set to a length obtained by adding the change dimension in the short direction due to thermal expansion to the standard short direction dimension of the solar panel P (the length dimension in the short direction at normal temperature). Since the solar panels P are formed with a plurality of module dimensions, a plurality of types of installation jigs 50 are created according to the dimensions of each solar panel.

  Next, the installation method of the solar panel P including the installation method of a base frame is demonstrated, referring FIG. 5 thru | or FIG. As shown in FIG. 5, first, the support block 43 is installed on the installation surface on the roof R, and then the base frame 30 is placed and fixed (first base frame fixing step). The support blocks 43 are installed at both ends in the longitudinal direction of the base frame 30. The foundation frame 30 is sequentially installed from the downstream side of the roof gradient.

  When the downstream base frame 30 is fixed, the installation jig 50 is brought into contact with the base frame 30, as shown in FIG. Specifically, the end portion of the first member 51 is moved while the first contact portion 53 of the first member 51 of the installation jig 50 is brought into contact with the upstream side surface of the protrusion 31 of the base frame 30. It is placed on the support portion 32 on the upstream side in the gradient direction X. The installation jig 50 is brought into contact at two locations on both ends in the longitudinal direction of the base frame 30 (see FIG. 5). While maintaining this state, the upstream base frame 30 is separately brought into contact with the second contact portion 61 of the second member 55 of the installation jig 50. At this time, the upstream-side base frame 30 is placed on the temporarily placed support block 43, and the second contact portion 61 is brought into contact with the downstream side surface of the ridge 31, so that the gradient direction X Is determined (second base frame positioning step). Here, the distance between the downstream base frame 30 and the upstream base frame 30 (the distance between the side surfaces of the protrusions 31, 31) is the same as the length of the installation jig 50, and the upstream base frame 30. Is positioned.

  When the installation position of the upstream base frame 30 is determined, the installation jig 50 is placed on the downstream support portion 32 to fix the base frame 30 to the roof R (second base frame fixing step). When the fixing of the base frame 30 to the roof R is completed, the installation jig 50 is removed. When the base frame 30 is installed, the bolt B is inserted from below into the bolt hole 31a of the ridge 31 of the base frame 30, and the body portion is protruded upward (FIG. 5). (Refer to the partial enlarged view). Using this bolt B, the joint water-stopping member 1 that extends along the base frame 30 is fixed in a later step. On the other hand, in the lowermost and uppermost base frames 30, bolt holes (not shown) are also formed between the base frames 30, 30 adjacent to each other in the orthogonal direction Y, and the bolts are inserted from below. The body portion is projected upward (not shown). Using this bolt, the joint water-stopping member 1 (see FIG. 2) extending in a direction orthogonal to the base frame 30 (gradient direction X) is fixed.

  When the installation of all the base frames 30 is completed, the solar panels P are installed from the downstream side as shown in FIG. The solar panel P is placed with the bottom surfaces of the upper and lower edge portions Pa in contact with the upper surface of the support portion 32, and the lower end surface (side surface) is brought into contact with the side surface of the ridge 31 and locked. (See FIG. 2). Here, when the temperature is high, such as in summer, the solar panel P expands to increase the short dimension, and the upper end of the solar panel P is also in contact with or close to the side surface of the ridge 31. . On the other hand, when the temperature is low such as in winter, the solar panel P contracts and the short dimension is reduced, and the upper end surface of the solar panel P is spaced from the side surface of the protrusion 31 ( Not shown). By arranging the solar panels P in this way, there is a joint 2 between the solar panels P and P (solar panels P and P adjacent in the gradient direction X) arranged so as to sandwich the protrusion 31 therebetween. (Hereinafter, sometimes referred to as “horizontal joint 2a”) extends in the orthogonal direction Y. The width of the horizontal joint 2a includes a width obtained by adding a shrinkage dimension in the short direction of the solar panel P due to heat shrinkage to the width dimension of the protrusion 31 from a length substantially equal to the width dimension of the protrusion 31. The dimension is in the range up to length.

  When installing the solar panel P in the direction adjacent to the orthogonal direction Y, the new solar panel P is arranged with a predetermined distance from the existing solar panel P and extends in the gradient direction X. Forming joints 2 (hereinafter sometimes referred to as “longitudinal joints 2b”). The joint width (width dimension in the orthogonal direction Y) of the vertical joint 2b is adjusted to the reference longitudinal direction dimension (the length dimension in the orthogonal direction Y at normal temperature) of the solar panel P by the change dimension in the longitudinal direction due to thermal expansion. Length.

  When the installation of the solar panel P is completed, the joint water-stopping member 1 is inserted into the joint 2 as shown in FIG. The joint water-stopping member 1 is installed above the protrusion 31 so that the body of the bolt B protruding from the base frame 30 is inserted into the bolt hole 31a of the protrusion 31. After the joint water-stopping member 1 is pushed into the joint 2 to some extent by hand, a nut N is attached to the bolt B and tightened. At this time, the elastic sealing material 20 is pressed against the back surface 11a of the surface portion 11 of the cover member 10 by the surface of the edge portion Pa of the solar panel P, and is covered by the side surface of the edge portion Pa of the solar panel P. Since it is pressed against the side surface 12a of the ten insertion portions 12, two sealing surfaces can be obtained. As a result, the seal area is increased and the necessary sealing performance can be ensured. At this time, since the elastic sealing material 20 is pressed using the side surface 53b of the edge portion Pa of the solar panel P, the pressing portion of the elastic sealing material 20 on the surface of the solar panel P can be reduced. Therefore, the area where the cover member 10 covers the surface of the solar panel P can be reduced, and the surface portion 11 does not cover the solar power generation cell 3, so that the reduction of the light receiving area can be suppressed.

  In addition, in this embodiment, as shown in FIG. 1, the joint water-stopping member 1 attached to the vertical joint 2b is configured to extend from the upper end to the lower end and pass through one piece, and the horizontal joint 2a. The joint joint water-stopping member 1 to be mounted is disposed for each solar panel P, and both ends thereof are in contact with the side surfaces of the joint joint water-stopping member 1 attached to the vertical joint 2b.

  Finally, as shown in FIG. 2, the cap member 25 covering the end portion of the bolt B and the nut N is covered, and the periphery of the bolt hole 13 in the surface portion 11 is sealed, so that the solar panel P can be installed. Complete.

  As described above, according to the installation method and the installation jig 50 of the foundation frame 30 of the solar panel P according to the present embodiment, a desired separation dimension set in advance according to the dimension of the solar panel P is set. Since the installation jig 50 provided is brought into contact with the downstream base frame 30 as a spacer to determine the installation position of the upstream base frame 30, it is possible to perform highly accurate positioning in mm units with easy work. it can. In addition, since marking is not performed as in the prior art, the work is easy and the accuracy is not affected by the skill level of the craftsman. Furthermore, even if the roof surface is uneven or undulated on the roof of a wooden house, the base frame can be positioned in units of mm.

  Further, the installation jig 50 is configured such that the first contact portion 53 and the second contact portion 61 have a certain length and are parallel to each other, so that the downstream base frame 30 and the upstream base frame are arranged. Parallel accuracy with the frame 30 can be ensured. Furthermore, in the present embodiment, the installation jig 50 is used at two locations on both ends in the longitudinal direction of the base frame 30, so that the same separation distance can be set on both ends in the longitudinal direction of the base frame 30. Therefore, the parallel accuracy between the base frames 30 and 30 can be further enhanced.

  The installation jig 50 is configured by joining the first member 51 and the second member 55, and the second member 55 is formed with a plurality of lengths and is attached to and detached from the first member 51. Since the connection is possible, it is possible to easily cope with a plurality of types of solar panels P only by exchanging the second member 55. Furthermore, when the installation jig 50 is not used, the accommodation space can be reduced by separating the first member 51 and the second member 55.

  As mentioned above, although the form for implementing this invention was demonstrated, this invention is not limited to the said embodiment, In the range which does not deviate from the meaning of this invention, a design change is possible suitably. For example, in the above-described embodiment, the first member 51 is brought into contact with the lower base frame 30 and the second member 55 is brought into contact with the upper base frame 30, but this is not a limitation. It may be used in the reverse direction.

  Moreover, the shape of the installation jig 50 is not limited to the above-described embodiment, and may be another shape. For example, in the said embodiment, although the length of the installation jig 50 is changed by joining the 2nd member from which length differs to the 1st member 51, a 2nd member is moved with respect to a 1st member. You may comprise so that it may attach and the length of the installation jig | tool 50 may be changed.
