PRECAST PANEL WITH PLASTERING-LIKE APPEARANCE

Abstract

A precast panel with plastering-like appearance is provided. The panel is built from a wooden substrate on which at least a mineral layer is prebuilt. When affixed to a wall, the wooden panel gives a visual effect simulating plastering. The panel has advantages inherited from its wooden substrate such as lightweight, economical and easy transportation, while exhibiting exclusive and fishable feeling like plastering, thereby serving as a low-cost yet high-quality choice for consumers.

Claims

1. A precast panel with plastering-like appearance, the precast panel comprising: a substrate; a waterproof layer, directly disposed on an upper surface of the substrate; an adhesive layer, combined on the waterproof layer; a mineral layer, combined on the adhesive layer; and a protective layer, combined on the mineral layer, wherein the mineral layer is made of ore or soil or the combination thereof.

2. The precast panel of claim 1, wherein the substrate is made of wood, cement or calcium silicate.

3. The precast panel of claim 1, wherein the adhesive layer is a layer of binding material for adhesion.

4. (canceled)

5. The precast panel of claim 1, wherein the protective layer is transparent or translucent.

BRIEF DESCRIPTION OF THE DRAWINGS

[0012] FIG. 1 is a perspective view of a precast panel according to one embodiment of the present invention.

DETAILED DESCRIPTION OF THE INVENTION

[0015] Referring to FIG. 1, in the present invention, a panel 1 is built from a substrate 11, on which a waterproof layer 12, an adhesive layer 13, a mineral layer 14 and a protective layer 15 are provided in sequence. Therein, the substrate 11 is preferably a wooden board, but it may alternatively be a cement slab or a calcium silicate board. The waterproof layer 12 serves to keep the substrate 11 dry and is made of a waterproof material. The adhesive layer 13 is made of a binding material for adhesion. The mineral layer 14 may be made of cement, ore, sand, soil or any combination thereof as long as it allows the adhesive layer 13 to adhere thereto. The protective layer 15 is either transparent or translucent, and serves to protect the mineral layer 14.

[0016] As shown in FIG. 1, with the wooden substrate 11, the disclosed panel 1 is lightweight and low-cost. Nevertheless, the external mineral layer 14 gives a plastering-like visual image. Thus, as the disclosed panel 1 is applied to building walls, as shown in FIG. 2, it desirably supports a decorative preference for industrial style.

[0017] Now refer to FIG. 3 for another embodiment of the present invention. The panel 1 is such built that a substrate 11 is first covered by a waterproof layer 12, and the waterproof layer 12 is covered by a mineral layer 16 that contains a composite binder, after which the binder-containing mineral layer 16 is covered by a protective layer 15. The binder-containing mineral layer 16 is actually a combination of the adhesive layer 13 and mineral layer 14 as described in the previous embodiment.

[0018] The mineral layer 14 is made substantively planar, and provides a visual effect simulating cement surface in terms of texture and color as needed.

[0019] The present invention provides the following benefits: [0020] First, the panel is lightweight so is easy to handle and transport. [0021] Second, the panel is prefabricated in the factory in a mass manufacturing manner, thereby ensuring consistent quality and low costs. [0022] Third, since the panel is premade, it can be quickly and easily fixed to the wall at the construction site, so the construction time is significantly reduced.
