Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated panels, in particular to a prefabricated decorative panel. Background Art

[0002] The shells left behind after eating oysters, scallops, abalone, etc. are usually classified as domestic waste. Take oyster shells as an example. They are hard and dense. As early as the Ming and Qing Dynasties, oyster shells were used to build oyster shell walls and oyster shell houses. The earliest oyster shell walls or oyster shell houses were built with oyster shells stacked layer by layer, with yellow mud, brown sugar, and steamed glutinous rice as bonding materials. They have many functions such as impact resistance, waterproof and moisture-proof, wind erosion resistance, salt corrosion resistance, waterproof, heat insulation, sound insulation, etc. The uneven architectural appearance of the oyster shell wall has a strong sense of sculpture and lines in visual photosensitivity, which is a unique architectural craft style in Lingnan architecture.

[0003] However, traditional oyster shell walls are usually built by on-site stacking technology, and the lower stacking part is often required to solidify to a certain degree before continuing to stack upwards. Otherwise, the deformation of the wall is difficult to control. This also results in a long construction period for the oyster shell wall, low construction efficiency, and severe environmental restrictions on construction. Utility Model Content

[0004] The utility model aims to provide a prefabricated decorative panel, which uses shells as decorative surfaces, utilizes waste, and has good thermal insulation, waterproof and sound insulation effects. It can be used to imitate oyster shell walls, greatly improve the construction efficiency of oyster shell walls, and shorten the construction period.

[0005] In order to achieve the above-mentioned purpose, the utility model discloses a prefabricated decorative panel, which includes a base layer, a decorative layer and embedded parts, the decorative layer is located outside the base layer, the decorative layer is formed by overlapping a number of shells, and the shells are partially inserted and fixed in the base layer; the embedded parts are placed in the base layer, and the embedded parts are partially exposed outside the base layer.

[0006] Preferably, the shell and the base layer are arranged at an angle of 15 to 60 degrees. This arrangement can make the adjacent shells and base layers cooperate, so that the natural arc-shaped cavity structure of the shell is more closed, which can better enclose the air, play a role in heat insulation and sound insulation, and when the utility model is used as an exterior wall decoration, this arrangement is also conducive to water repellency.

[0007] Preferably, the shell is inserted into the base layer to a depth of not less than 5 mm. The purpose of this arrangement is to ensure the connection stability of the shell and to ensure that the shell will not fall off easily.

[0008] Preferably, the cavities of all the shells are parallel to each other. This arrangement can make the decorative layer more regular, which is conducive to hydrophobicity and arrangement.

[0009] Preferably, the shells are arranged in a fish scale shape outside the base layer. This arrangement can make it more difficult for rainwater to overflow into the base layer when the utility model is used as an exterior wall decoration, and the appearance is more beautiful.

[0010] Preferably, the base layer is a foamed cement layer. The base layer arranged in this way is lighter and is conducive to reducing the weight of the wall.

[0011] Preferably, the base layer is a biochar foamed cement layer. Such a base layer can make the biochar fully utilize the air bubbles in the foamed cement layer to achieve the carbon fixation function, which is more environmentally friendly.

[0012] Preferably, the embedded part is a pad, which is arranged inside the base layer, and a connecting pipe is arranged on the pad, and both ends of the connecting pipe are exposed outside the base layer. By providing the pad, it is convenient to ensure the stability of the position of the embedded part when it is embedded.

[0013] Preferably, a hydrophobic protective layer is also provided on the surface of the decorative layer. By providing the hydrophobic protective layer, the waterproof and moisture-proof function can be further enhanced.

[0014] The utility model has the following beneficial effects:

[0015] The utility model forms a decorative layer by partially inserting and fixing the shells on the outside of the base layer, which can play the decorative effect of the oyster shell wall. Moreover, because it is prefabricated, the utility model can be conveniently and quickly installed on site by using embedded parts, with high construction efficiency and little environmental influence. In addition, the utility model uses shells as a decorative layer, turning waste into treasure, and uses the natural waterproof and salt corrosion resistance of shells, so that the utility model also has these characteristics. At the same time, the natural arc cavity structure of the shells can be used to enclose air, so that the utility model has good thermal insulation and sound insulation effects.

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] like Figures 1 to 3 As shown, the utility model discloses a prefabricated decorative panel, which includes an embedded part and a base layer 10, a decorative layer 20 and a hydrophobic protective layer 30 arranged in sequence, that is, the decorative layer 20 is arranged outside the base layer 10, and the hydrophobic protective layer 30 is arranged on the outer surface of the decorative layer 20. By arranging the hydrophobic protective layer 30, the waterproof and moisture-proof function of the decorative panel can be enhanced.

[0027] The decorative layer 20 is formed by overlapping a number of shells 21. It is best if the cavities of these shells 21 are parallel to each other. This parallelism is the goal. Considering that the shapes of the shells 21 are different, if it is rigidly stipulated that the cavities of the shells 21 must be parallel to each other, it is difficult to achieve and the operation will be very troublesome. Therefore, in this case, the cavities of the shells 21 are required to be parallel to each other, and it is only necessary to get as close to this goal as possible. By making the cavities of the shells 21 parallel to each other, the decorative surface of the overlapping shells 21 can be made more regular. When installing on the wall, it is only necessary to make the cavities of the shells 21 obliquely downward, that is, the shells 21 are set at an angle of 15 to 60 degrees with the base layer 10 (i.e., angle A in the figure), which can ensure that the natural arc cavity structure of the shells 21 will not accumulate water. It is further preferred that the shells 21 are set at an angle of 45 degrees with the base layer 10, and the shells 21 are arranged in a fish scale shape outside the base layer 10. After such arrangement, the carrying density and weight of the shell 21 can be balanced, which is both beautiful and convenient to manufacture.

[0028] The shell 21 is partially inserted and fixed in the base layer 10 to achieve the installation and fixation of the shell 21. The depth H of the shell 21 inserted into the base layer 10 is preferably not less than 5 mm to ensure the connection strength of the shell 21. In this case, the base layer 10 is a foamed cement layer, that is, it is obtained by solidifying the foamed cement in a mold. The shell 21 can be inserted before the foamed cement is solidified, and it can be fixed after the foamed cement is solidified. The weight of the foamed cement is light, which is conducive to reducing the overall weight of the decorative board. In addition, the base layer 10 is further preferably a biochar foamed cement layer. Biochar has a good carbon fixation effect. It can make full use of the bubble holes in the foamed cement for dispersion and carbon fixation, which is green and environmentally friendly.

[0029] The embedded part is placed in the base layer 10, and the embedded part partially extends out of the inner surface of the base layer 10. Specifically, the embedded part includes a pad 41, which is arranged inside the base layer 10, and the plate surface of the pad 41 is parallel to the plate surface of the base layer 10. A connecting pipe 42 is integrally formed on the pad 41, and the connecting pipe 42 has a certain length, which is equal to or slightly exceeds the thickness of the base layer 10. Both ends of the connecting pipe 42 can be exposed from the base layer 10. The pad 41 can be built-in and fixed in the mold before the mold of the base layer 10 is made.

[0030] During installation, a hole equal to the inner diameter of the connecting tube 42 is opened on the wall, and then the expansion tube 51 is inserted. The expansion tube 51 can be completely inserted into the hole in the wall, or the expansion tube 51 is inserted to the bottom and placed in the hole in the wall and the connecting tube 42 at the same time. In this way, the decorative panel can be pre-fixed, and then the expansion nail 52 is screwed in so that the expansion nail 52 expands the expansion tube 51, so that the decorative panel and the wall are fixed, and the end cap of the expansion nail 52 abuts the connecting tube 42 to prevent the decorative panel from loosening.

[0031] The key point of the utility model is that the shell 21 is partially inserted and fixed on the outside of the base layer 10 to form a decorative layer 20, which can play the decorative effect of the oyster shell wall, and because it is prefabricated, the utility model is installed on site through embedded parts, which is more convenient to install, has high construction efficiency, and is less affected by environmental factors. In addition, the utility model uses the shell 21 as the decorative layer 20, turning waste into treasure, and utilizing the natural waterproof and salt corrosion resistance of the shell 21, so that the utility model also has this characteristic, and at the same time, utilizing the natural arc cavity structure of the shell 21, it can enclose the air, so that the utility model has good thermal insulation and sound insulation effects.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
