It is related to. [Prior Art] Generally, when panels are used to form a wall for covering, so-called joints are formed where the ends of the panels face each other, and a cover that serves as a waterproofing material or a decorative material is applied to these joints. It is common for the concrete to be installed. In other words, conventionally used cover materials are made by laying a cover wider than the joint width, and fixing the cover by driving nails into the top of the cover, or by pulling the bottom end to the side joint of the panel. Generally known are covers whose upper ends are fixed with nails or the like, or which are simply filled with joint material between the joints. [Problems to be solved by the invention] However, when vertical joints are formed as described above, fixing tools such as nails are exposed on the decorative surface, spoiling the aesthetic appearance, and being inferior in waterproofness, workability, and productivity. There was a risk that the cover would come off due to earthquakes, etc. [Means for solving the problem] In order to eliminate such drawbacks, the present invention provides a joint cover locking body (padding board) having a fitting groove.
A narrow-width decorative piece is formed by forming board material using rolls, presses, etc. to correspond to the shape of the decorative end of the panel, and a bottom edge of the decorative piece is bent inward and extended to the center of the back side of the decorative piece. a decorative surface portion consisting of an edge; a rising portion that projects downward from the lower edge and is formed from the upper end to the lower end with a height corresponding to the cross-sectional shape of the panel; and The engaging portion is formed of a plurality of engaging protrusions protruding outwardly so as to be insertable, and the longitudinal section is formed into a T-shape, and the lower edge and the rising portion on the engaging protrusion forming portion are bent. A cutout groove is provided in the part with a width greater than the width of the engaging protrusion, and a horizontal joint cover is provided in the decorative surface part with the lower end bent inward at a height corresponding to the stepped part of the panel. By providing a waterproof piece with a decorative piece protruding from the upper edge, waterproofness and aesthetics can be improved simply by engaging the engaging part of the cover with the joint cover locking body. Furthermore, we propose a cover that is easy to form and has good workability and does not come off.
