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 normal 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 where joint material is simply filled 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, being inferior in waterproofness and workability, and causing problems such as earthquakes. There was a risk that the cover would come off. [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 a plate material using rolls, presses, etc. to correspond to the shape of the decorative end of the panel, and the longitudinal edges of the decorative piece are bent inward to reach the center of the back side of the decorative piece. a decorative surface part consisting of an extended back bottom piece; a rising part formed from the top end to the bottom end of the back bottom piece so as to protrude outward, and having a shape substantially identical to the cross-sectional shape of the panel; The engaging portion is formed into a T-shape in longitudinal cross section, and the engaging portion is formed of a plurality of engaging protrusions protruding outwardly so as to be insertable. By forming a horizontal joint fitting part on the ground engaging part and the upper edge, the engaging part of the cover and the fitting groove of the joint cover locking body can be engaged, and the horizontal joint engaging part and the horizontal joint can be fitted. The present invention proposes a cover that has a double engagement structure in which the parts engage, and that improves waterproofness and aesthetics by simply engaging without using nails, and is also easy to install and does not come off. [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 denotes the cover, which is formed from a plate material into a T-shaped cross section by roll forming, press forming, or injection molding. To explain further, the cover 1 is made of a plate thickness and material that can exhibit elasticity, such as a metal plate (color steel plate, PVC steel plate, aluminum plate, etc.).
It is formed from a stainless steel plate, a copper plate, etc.) into the above-mentioned cross-sectional shape. That is, the cover 1 includes a decorative surface part 2 , an engaging part 4 protruding along the longitudinal direction at the center of the back surface thereof, a horizontal joint engaging part 7 provided at the lower edge of the decorative surface part 2 , and a horizontal joint engaging part 7 formed at the upper edge.
