[0040] To keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of known functions and known components are omitted in the present invention.

[0041] As Figures 1 to 4 shown, an embodiment of the present invention discloses a wall panel unit, which is prefabricated in a factory.

[0042] The wall panel unit includes a decorative panel 20, a rear plate body 10, a foamed foam 30, a first barrier member 41 and a second barrier member 42; the rear plate body 10 is fastened to the rear side of the decorative panel 20 and encloses a cavity with the decorative panel 20. A through hole 14 is formed in the top wall of the rear plate body 10, and the foamed foam 30 is filled into the cavity through the through hole 14.

[0043] First barrier members 41 are formed on the inner sides of the two side walls 11 of the rear plate body 10, and the first barrier members 41 extend into the cavity; a second barrier member 42 is formed on the rear surface of the decorative panel 20, and the second barrier member 42 extends into the cavity. After the foamed foam 30 is filled into the cavity and the foamed foam 30 solidifies, the first barrier members 41 extend into the foamed foam 30, thereby restricting the separation of the rear plate body 10 from the foamed foam 30 in the thickness direction, and the second barrier member 42 extends into the foamed foam 30, thereby restricting the separation of the decorative panel 20 from the foamed foam 30 in the thickness direction. Thus, the first barrier members 41 and the second barrier member 42 can effectively prevent the rear plate body 10 and the decorative panel 20 from separating from the foamed foam 30.

[0044] There are various structures and forming methods for the first barrier member 41 and the second barrier member 42. For example, as Figure 1 and Figure 2 shown, the first barrier member 41 is formed by bending the side wall 11 of the rear plate body 10 towards the cavity; for another example, as Figure 3 and Figure 4As shown, the first barrier member 41 is formed by an angle steel with an attachment portion. Specifically, the attachment portion is attached to the inner side of the rear plate body 10, and the screw 111 penetrates the attachment portion from the outside so that the angle steel can be fixed.

[0045] For another example, the second barrier member 42 is composed of two symmetrically arranged inclined slats. Specifically, the root of the inclined slat has an attachment plate 421, and the attachment plate 421 is adhesively bonded to the inner side of the decorative plate 20 by a colloid. In this way, the two symmetrically arranged inclined slats extend symmetrically into the gap. The advantage of using the two symmetrically arranged inclined slats as the second barrier member 42 is that it enhances the bonding strength between the decorative plate 20 and the foamed foam 30.

[0046] In some preferred embodiments, the side edge of the rear plate body 10 is bent to form a butt plate 12 and a bent snap portion 13 in sequence. The butt plate 12 is adhesively bonded to the inner plate surface of the decorative plate 20 by a colloid, and the bent snap portion 13 is used to enable adjacent two wallboard units to be butted by a fastener.

[0047] The decorative plate 20 can be made of various materials. For example, it can be made of calcium silicate board. For another example, the decorative plate 20 is a ceramic tile.

[0048] The decorative plate 20 of the wallboard unit disclosed in the present invention is preferably a ceramic tile, and the second barrier member 42 greatly increases the bonding force between the ceramic tile and the foamed foam 30.

[0049] The process of manufacturing the above wallboard unit is introduced below:

[0050] First, place the ceramic tile with the second barrier member 42 pre-fixed on a platform with the rear side of the ceramic tile facing up; then, buckle the rear plate body 10 with the first barrier member 41 pre-formed on the ceramic tile, and pre-bond the butt plate 12 and the ceramic tile by applying a colloid on the butt plate 12 of the rear plate body 10; then, set a limit die above the rear plate body 10, and the limit die is used to limit the upward movement of the rear plate body 10 when filling the foamed foam 30; finally, fill the cavity with the foamed foam 30 through the through hole 14 on the top wall of the rear plate body 10. Under the limitation of the limit die, the foamed foam 30 fills the cavity in a relatively dense state. After the foamed foam 30 solidifies, the wallboard unit is completed.

[0051] The present invention also discloses a wall surface system composed of the above wallboard units arranged in sequence.

[0052] Moreover, although exemplary embodiments have been described in the present invention, the scope thereof includes any and all embodiments based on the present invention having equivalent elements, modifications, omissions, combinations (e.g., schemes intersecting various embodiments), adaptations or alterations.
