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 those in which the gaps between the joints are simply filled with joint material. [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. Furthermore, if individual covers were damaged, they could not be replaced. [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.

and an engaging portion consisting of a plurality of or continuous engaging protrusions protruding outwardly so as to be insertable;
The vertical section is formed into a T-shape, and the lower end in the longitudinal direction of the rising portion is cut out over a range equal to or greater than the depth of the engagement groove of the panel, and the lower end is cut inward on the decorative surface portion. A horizontal joint cover piece is provided bent at a height corresponding to the stepped part of the panel, and a decorative piece is protruded from the upper edge to form a waterproof piece, thereby locking the engaging part of the cover to the joint cover. The present invention proposes a cover that improves waterproofness and aesthetics by simply engaging with the body, has good workability, and is easy to mold without detachment. [Embodiment] An embodiment of the cover according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view showing the above-mentioned cover. Reference numeral 1 designates the cover, which is formed into a T-shaped cross section by roll molding, press molding, extrusion molding, injection molding, firing, or the like. To explain in more detail, the cover 1 is made of, for example, a metal plate (color steel plate, PVC steel plate, aluminum plate, stainless steel plate,
It is formed integrally by the above-mentioned method from one or more of the following: copper plate, galvalume steel plate, galvanized steel plate, clad steel plate, vibration damping steel plate, sandwich steel plate, titanium alloy plate, etc.), synthetic resin plate, ceramic plate, ceramic plate, etc. An example of a board is shown.
