Other existing decorative components cannot meet the design effect of the edge, especially when the luminous design of the light strip is required; resulting in the lack of finished decorative components when the existing prefabricated wall panels are used in the background wall. Therefore, the following embodiments are proposed in this solution to solve the above problems through the improved structure of the circular arc closing component.

[0042] Embodiment 1

[0043] See also Figure 1 , Figure 2The present embodiment provides an arc closing component 100 for closing the edges of the wallboard 200 and the background wallpaper 300. For the convenience of structural description, the wallboard 200 and the background wallpaper 300 set on the wall 700 of the building are used as an example for structural description, with the side of the wall 700 facing the user as the front, the opposite side as the back, and the direction perpendicular to the front and back directions in the horizontal plane as the left and right directions. Each structure in the present embodiment is described with reference to the above directions.

[0044] Usually, the wall panels 200 are arranged on the left and right sides of the background wallpaper 300, and the arc closing component 100 is arranged on the wall panels 200 on the left and right sides. For the convenience of structural description, the arc closing component 100 on the left side is taken as an example for structural description. The arc closing component 100 of this embodiment mainly includes: an arc closing part 110, a decorative part 120, a connecting and fixing part 130 and a wallpaper closing part 140. The side of the arc closing part 110 facing the right side is the outer side surface, and the outer side surface protrudes away from the direction of the wall panel 200, and the side surface is an arc shape. When connected to the edge of the wall panel 200, the outer side surface of the arc shape blocks the edge of the wall panel 200, so that the edge of the decorative wall structure forms a smooth transition, making the edge closing more beautiful. The decorative part 120 is arranged at the front end of the arc closing part 110, and is used to cover the outer surface of the wall panel 200, and the front surface of the decorative part 120 is used to match the front surface of the wall panel 200. Thus, the edge of the wallboard 200 can be trimmed so that the edge of the wallboard 200 will not be exposed. Moreover, the front surface of the decorative part 120 can be coated with a decorative film of the same color as the wallboard 200, so that it can match the front surface of the wallboard 200 in visual matching, so that the pattern and color matching on the decorative surface of the entire wallboard 200 presents aesthetics, achieving a decorative design effect. The connecting and fixing part 130 is arranged on the arc closing part 110, and an installation space 150 is formed between the connecting and fixing part 130 and the decorative part 120, and the installation space 150 is used to embed the edge of the wallboard 200; the connecting and fixing part 130 is used to be fixed on the keel 400 of the wall 700, so that the entire arc closing component 100 can be relatively fixed to the wall 700. The wallpaper closing part 140 is arranged at the rear end of the arc closing part 110, and is used to cover the front surface of the edge of the background wallpaper 300; so as to close the edge of the background wallpaper 300, so that the edge of the background wallpaper 300 will not be exposed, and achieve a better closing decorative effect.

[0045] See also Figure 2 , Figure 4The working principle of the arc closing component 100 provided in this embodiment is as follows: the arc closing component 100 can form a standardized finished component, so it is widely used in the edge finishing structure of the background wall. The arc closing part 110 is connected to the edge of the wall panel 200 by connecting the fixing part 130, and is sleeved on the outer side of the edge of the wall panel 200. The front side of the edge of the wall panel 200 is shielded by the front decorative part 120, and the front surface of the decorative part 120 is used to match the front surface of the wall panel 200, so that the edge of the wall panel 200 can be closed and the edge of the wall panel 200 will not be exposed. Moreover, the front surface of the decorative part 120 matches the front surface of the wall panel 200 in visual matching, so that the pattern and color matching on the decorative surface of the entire wall panel 200 are consistent, achieving a decorative design effect. The wallpaper closing portion 140 covers the front edge surface of the background wallpaper 300 to close the edge of the background wallpaper 300, so that the edge of the background wallpaper 300 will not be exposed, achieving a better closing decorative effect, so that the entire background wall not only has a sense of hierarchy, but also the closing at the edge is more beautiful. As a finished component, the arc closing component 100 can be more conveniently adapted to the wallboard 200 and can be directly used at the construction site, thereby reducing the processing difficulty, reducing the construction steps and time, reducing the decoration cost, and greatly facilitating the decoration construction process.

[0046] See also Figure 2 , Figure 4 Further, the facing part 120 in this embodiment includes a facing panel 121, which extends to the left by a predetermined length. The facing panel 121 is integrally formed with the arc closing part 110, so as to facilitate the processing of the arc closing component 100. The right edge of the wallboard 200 is shielded by the facing panel 121. A facing layer is provided on the facing panel 121, and the facing layer is consistent with the pattern of the wallboard 200, or the facing layer can be various colors of spray design, or can be consistent with the color of the wallboard 200. Therefore, the decorative effect of the visible surface (front surface) of the facing panel 121 is unified with that of the wallboard 200 through the facing layer. In this way, the front surface of the facing part 120 matches the front surface of the wallboard 200 in visual matching, so that the pattern and color matching on the decorative surface of the entire wallboard 200 are consistent, and the decorative design effect is achieved.

[0047] The decorative effect of the arc outer surface (the outer side facing the right side) of the arc closing portion 110 in this embodiment is unified with the wall panel 200 or spray-painted in various colors. Thus, the visible surface of the arc closing portion 110 matches the front surface of the wall panel 200 in visual matching, so that the pattern and color matching on the decorative surface of the entire wall panel 200 are consistent.

[0048] See also Figure 2 , Figure 4Furthermore, in this embodiment, a limiting rib 123 is provided on the inner side wall of the facing portion 120 facing the connecting and fixing portion 130. The limiting rib 123 extends toward the connecting and fixing portion 130 and forms a limiting step with the facing portion 120. The limiting step is used to clamp and limit the edge of the wall panel 200. In the specific structure, the limiting rib 123 is integrally formed with the facing panel 121. The limiting rib 123 extends backward by a predetermined length. When the wall panel 200 is inserted into the installation space 150, the inner wall of the facing panel 121 and the connecting and fixing portion 130 limit the wall panel 200 at the front and rear sides. In the insertion direction, the limiting rib 123 limits the wall panel 200, thereby ensuring the accuracy of the installation position of the wall panel 200. The accurate position can be achieved by directly inserting the wall panel 200 into the installation space 150, which is convenient for installation.

[0049] See also Figure 2 , Figure 4 Furthermore, the connection and fixing part 130 in this embodiment includes a horizontal side plate 131, which is connected to the inner wall of the arc closing part 110 and extends to the left side to set a predetermined length. The horizontal side plate 131 and the arc closing part 110 are integrally formed, which is convenient for processing. The horizontal side plate 131 is used to be fixed to the keel 400 on the inner side of the wall panel 200 by screws. In this way, the arc closing part 110 is fixed to the wall 700 through the keel 400. When the wall panel 200 is embedded in the installation space 150, the wall panel 200 and the keel 400 can be stably fixed.

[0050] Furthermore, in this embodiment, the horizontal side plate 131 is provided with abutting bosses 132, which are formed by bending the sheet metal of the horizontal side plate 131, and the rear surface of the abutting bosses 132 is used to abut against the surface of the keel member 400. The abutting bosses 132 abut against the keel member 400, providing a support position for the fixation of the horizontal side plate 131, and the contact with the surface of the keel member 400 only occupies a small part of the horizontal side plate 131, thus avoiding the contact between the surface of the entire horizontal side plate 131 and the surface of the keel member 400, thereby avoiding the problem of unstable surface-to-surface connection caused by the overall uneven surface of the keel member 400.

[0051] The front side of the boss 132 is concave due to the bending of the sheet metal to form a groove 133, and the groove 133 is used to accommodate the screw head. When the screw passes through the horizontal side plate 131 and is driven into the keel member 400, the screw head can be in the groove 133 without protruding, and will not affect the installation of the wall panel 200.

[0052] Furthermore, in this embodiment, a screw groove 134 is provided on the side of the abutting boss 132 away from the keel member 400. The screw groove 134 is a V-shaped groove, and the screw is directly driven into the horizontal side plate 131 at the screw groove 134, so that the screw is accurately driven into the position and the screw is not easy to be tilted.

[0053] Furthermore, one end of the horizontal side plate 131 in this embodiment is connected to the arc top position of the inner wall of the arc closing part 110. The arc top position of the inner wall of the arc closing part 110 has a high structural strength, and the pressure bearing capacity of the arc top position is strong. The connection structure of the horizontal side plate 131 and the arc closing part 110 is stable and not easy to break.

[0054] See also Figure 2 , Figure 4 Furthermore, the wallpaper closing portion 140 in this embodiment specifically includes: a vertical connection plate 141 and a closing side plate 142. The vertical connection plate 141, the closing side plate 142 and the arc closing portion 110 are integrally formed. The vertical connection plate 141 is connected to the end (the leftmost end) of the rear part of the arc closing portion 110, and extends toward the background wallpaper 300; the vertical connection plate 141 extends a predetermined length toward the rear, and is connected to the closing side plate 142 at the end, and the closing side plate 142 is vertically connected to the end of the vertical connection plate 141 away from the arc closing portion 110, and extends a predetermined length toward the right side. A light strip groove 143 is formed between the vertical connection plate 141 and the closing side plate 142, and the light strip groove 143 is used to install the light strip 800. The light strip groove 143 provides an installation position for the light strip 800, so that the light strip 800 can be blocked by the arc closing portion 110, thereby hiding the light strip 800. The light strip groove 143 is a prefabricated size. When the light strip 800 is installed in the light strip groove 143, the fixed angle of the light strip 800 is accurate, which can ensure that the light of the light strip is irradiated from the side to achieve a diffuse reflection decorative effect. The closing edge plate 142 is pressed on the front surface of the background wallpaper 300 to cover the background wallpaper 300. The gap between the closing edge plate 142 and the background wallpaper 300 can be glued to achieve a beautiful closing effect.
