[0002] Building decorative boards are materials used for interior and exterior decoration of buildings, and are usually used for decoration and beautification of walls, ceilings, floors and other parts. Building decorative boards can not only beautify the appearance of buildings, but also play a role in protecting the structural function, and are one of the commonly used materials in building decoration.

[0003] Existing building decorative boards are usually made of wood boards, PVC boards, gypsum boards and metals, and are mostly single-board settings. The sound waves of external noise are easy to pass through the decorative boards, resulting in poor sound insulation performance for noise; moreover, bolts are mostly used in cooperation with clamping strips to connect between the boards, and there are gaps at the joints. External water of the decorative board is easy to penetrate through the gaps to the back side of the decorative board, resulting in poor waterproof performance of the decorative board. For this reason, we propose a composite building decorative board. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment

[0024] Please refer to Figures 1-4 , a composite building decorative board in the figure, including:

[0025] A clamping strip 101 is provided on the side wall of the plate body 100;

[0026] In some embodiments, the plate body 100 is internally made of a common waterproof plastic film, a wooden board layer, and heat-insulating asbestos on the market. The plate body 100 and multiple sound insulation sheets 200 are combined to form a composite decorative board.

[0027] An upper fixing member 110 is fixedly connected to the outer wall of the plate body 100. A pressing strip 130 is arranged inside the upper fixing member 110. A lower fixing member 120 is arranged at the bottom of the pressing strip 130. The pressing strip 130 includes a plastic film 132 and a rubber strip 133 arranged on the side wall of the plastic film 132. The rubber strip 133 is made of common soft rubber on the market. A hard strip 131 is arranged on the outer wall of the pressing strip 130. The hard strip 131 is made of hard plastic. A connecting strip 134 fixed to the upper fixing member 110 is arranged at the top of the pressing strip 130. A plurality of pressing bolts 121 are arranged on the side wall of the lower fixing member 120. Threads matching the pressing bolts 121 are arranged inside the lower fixing member 120. The pressing bolts 121 are matched with the side wall of the hard strip 131;

[0028] The multiple sound insulation sheets 200 are arranged at the rear side of the plate body 100. The multiple sound insulation sheets 200 include a wooden layer 220, a waterproof film 231 arranged at the rear side of the wooden layer 220, a sound insulation cotton layer 230 arranged at the rear side of the waterproof film 231, and a plastic sheet 240 arranged at the rear side of the sound insulation cotton layer 230. The waterproof film 231 is a common plastic film. The sound insulation cotton layer 230 is made of common sound insulation cotton on the market and is made of polyester fiber. The main function of the sound insulation cotton is to reduce the transmission and reflection of sound by absorbing and dissipating sound wave energy, so as to achieve the sound insulation effect. The plastic sheet 240 is made of common wear-resistant plastic on the market. A plurality of arc-shaped grooves 222 are formed on the side wall of the multiple sound insulation sheets 200. Sound absorption blocks 223 are arranged inside the arc-shaped grooves 222. The inside of the arc-shaped grooves 222 is smooth. The sound absorption blocks 223 are made of common foam plastic on the market. A plurality of holes with a large outer and small inner diameter are formed on the side wall of the foam plastic. Sound waves entering the holes can be weakened by the foam plastic.

[0029] Specifically, the lower fixing member 120 is fixed to the outer wall of the plate body 100.

[0030] Furthermore, a fixing strip 210 is provided on the outer wall of the multi-layer sound insulation sheet 200. The fixing strip 210 is made of a common stainless steel strip on the market, which can fix the multi-layer sound insulation sheet 200 to the rear side of the main body 100.

[0031] Still further, the clamping strip 101 has a cuboid structure.

[0032] Still further, an adhesive sheet 221 is provided on the side wall of the multi-layer sound insulation sheet 200. The adhesive sheet 221 is a soft plastic sheet, and its side wall is coated with a common resin glue.

[0033] It should be noted that the fixing strip 210 is embedded in the outer wall of the plate body 100.

[0034] It should be noted that the pressing strip 130 is fitted to the outer wall of the plate body 100.

[0035] In addition, the above-mentioned electrical components and electrical equipment all use an external power supply. The circuits, electronic components and modules involved in the present utility model are all prior arts, which can be fully realized by those skilled in the art without further elaboration. The content protected by the present utility model does not involve improvements to the internal structure and method either.

[0036] Working principle: By providing an arc-shaped groove 222 with a sound absorption block 223 and an internal sound insulation cotton layer 230 on the multi-layer sound insulation sheet 200, the sound absorption block 223 of the arc-shaped groove 222 and the sound insulation cotton 230 are used to absorb and block sound, thereby improving the sound insulation performance of the composite building decorative board, reducing the noise passing through the composite building decorative board, and increasing the comfort of the building after the decorative board is installed. By providing a pressing strip 130 fitted inside the upper fixing member 110 and the lower fixing member 120, and turning the pressing bolt 121 to press the pressing strip 130, the pressing strip 130 is used to seal the connection between the two plate bodies 100, thereby realizing the sealing of the connection gap of the composite building decorative board, preventing the water outside the decorative board from penetrating to the rear side of the decorative board through the gap, and improving the waterproof performance of the decorative board.

[0037] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.
