Description

Coating aid for adhesive coating for mounting solar panel bracket Technical Field The present invention relates to an auxiliary coating tool for coating an adhesive for mounting a solar panel bracket. Background There is known a technique of attaching a solar power module to an object such as a roof of a house via a bracket for attaching the solar power module. As an example of such a bracket, the mounting battery plate described in patent document 1 is adhesively fixed to an object via an adhesive. Patent document 1 Japanese patent laid-open publication No. 2002-4525 Disclosure of Invention When the solar panel holder is mounted on the object using an adhesive, an appropriate amount of the adhesive needs to be applied in an appropriate range. However, in the conventional method, there are cases where the coating amount of the adhesive or the coating range varies depending on the operator, and it is difficult to ensure the quality of the mounting work in the solar panel holder. The present invention can be implemented in the following manner. (1) According to one aspect of the present invention, there is provided an adhesive application assisting tool for attaching a solar panel holder. The coating auxiliary tool comprises an outer frame part and an opening forming part, wherein the opening forming part is provided with a plurality of openings for the adhesive to pass through, the opening forming part is provided with a plurality of annular beam parts arranged in a mosaic shape and a plurality of cross beam parts connected with the outer frame part and crossing the annular beam parts, and the plurality of openings are formed by penetrating holes in the thickness direction surrounded by the annular beam parts and the cross beam parts. According to the application assisting tool of this aspect, since the opening forming portion is provided with the plurality of openings through which the adhesive passes, the operator can apply the adhesive to the object by flowing the adhesive into the opening forming portion, and it is possible to suppress variations in the amount of the adhesive applied or the range of application caused by the operator. Therefore, the construction quality of the mounting work in the solar panel bracket can be ensured. Further, since the opening forming portion has a plurality of annular beam portions and a plurality of intersecting beam portions, each annular beam portion and each intersecting beam portion form an annular channel and an intersecting channel, respectively, to which an adhesive is not applied, in the applied structure as an adhesive in an applied state. Accordingly, the alcohol-based by-product generated from the coating structure can be discharged to the outside through each annular channel and each intersecting channel intersecting each annular channel. Therefore, the curing time of the coating structure can be shortened, and the solar panel bracket can be efficiently mounted. (2) The coating auxiliary tool according to the above aspect further includes a central portion which is located at the center of the outer frame portion and is connected to the plurality of cross beam portions, the central portion having a central rectangular portion having a rectangular shape, and a pair of central semicircular portions which are adjacent to one opposite side of the central rectangular portion, respectively, and have a semicircular shape connected to the central rectangular portion, the opening forming portion having a pair of opening rectangular portions which are adjacent to the other opposite side of the central rectangular portion, respectively, and have a rectangular shape connected to the central rectangular portion, and a pair of opening semicircular portions which are connected to both of the pair of opening rectangular portions, and have a semicircular shape surrounding the central semicircular portion which is different from each other among the pair of central semicircular portions. According to the coating auxiliary tool of this embodiment, the plurality of intersecting beam portions are connected to the central portion, so that the strength of the intersecting beam portions can be improved as compared with a structure in which the central portion is not provided. Further, since the application assisting tool includes the center portion where the adhesive is not applied, the amount of the adhesive to be used can be suppressed while maintaining the adhesive strength of the adhesive. (3) In the coating auxiliary tool according to the above aspect, when a steel plate which is a part of the solar panel holder and has a shape corresponding to the shape of the coating structure is attached to the coating structure which is the adhesive in the coated state formed by flowing the adhesive into the opening forming portion, the steel plate is provided with a supporting portion located at the center of the steel plate, the supporting portion has a rectangular supporting portion hav
