It is proposed in Japanese Patent Publication No. 57-36741. Further, a support portion is provided at the center of the surface of the backing plate, and a cover is attached to the support portion so that the joint portion of the surface structure material is covered by the cover. It is proposed by Japanese Patent Publication No. 60-3867.

[Problems to be Solved by the Invention] In the above-mentioned prior art, since the backing plate is not provided with a function of accurately positioning and fixing the backing plate in a predetermined direction with respect to the backing plate, when mounting the backing plate on the backing plate The backing plate may be displaced by an impact or the like, and as a result, the backing plate a may be tilted with respect to the surface structural material b as shown in FIG. 7. In this case, the cover c for blinding the seam portion is backed. As in the case of the contact plate a, there is a problem that the cover c inclines and a plurality of covers c in the same row do not appear on a straight line, resulting in poor appearance.

In Japanese Utility Model Laid-Open No. 54-152526, a surface structural material having an engaging portion at the upper edge and a bent engaging portion at the lower edge is used, and the engaging portion of the surface structural material laid in the lower stage is covered from above. In a connecting structure in a surface structure material that is covered and fitted and is laid in a zigzag shape as a whole, a receiving member formed by extending the receiving piece outward on both sides along the vertical direction of the waste plate attached to the base material side. By mounting, a receiving portion is formed between the lower surface of the receiving piece and the upper surface of the waste plate, and the edges of a pair of left and right surface structural materials laid next to each other at the same height position are inserted into the upper receiving portion. There is disclosed a connecting structure in a surface structure material in which a decorative plate is covered on the surface structure material.

However, since the bottom plate of the connection structure described in Japanese Utility Model Laid-Open No. 54-152526 is formed by bending the lower end of the plate material on which the ridges 12, 12, ... Are formed over the entire width, it is difficult to form it. There is a problem that the bend forming portion is apt to bend, and thus it is difficult to accurately position it. Further, in the connection structure, there is a problem that the water leakage between the top and bottom of the waste plate and the surface structure material is not always sufficient.

Further, in Japanese Patent Laid-Open No. 63-277352, in a joint cover for covering a joint portion of a roofing material for roofing, a decorative surface portion for covering an edge surface of the roof material and a rear surface of the decorative surface portion are provided. Disclosed is a joint cover which is composed of an anchor portion, and has an adhesive layer provided on both back surfaces of the decorative surface portion, and the anchor portion is formed by two legs protruding from the decorative surface portion. Adhesive layer of this joint cover is
Although it can be considered to be used for the scrap plate of the connection structure described in Japanese Patent No. 2526, it is said that it is difficult to accurately position the scrap plate with respect to the plane structure material because the bending formation portion of the scrap plate is bent. The problem has not been solved at all, and even if an adhesive layer is provided in a state where the bending formation portion is bent, the adhesive layer cannot be accurately positioned, so that there is a problem that sufficient water leakage cannot be exhibited. is there.

Therefore, an object of the present invention is to provide a backing plate having a positioning and fixing function.
