Abstract
Description
Technical Field
[0001] This utility model relates to the field of composite board technology, specifically a composite board with sound insulation and noise reduction functions. Background Technology
[0002] Composite panels are building materials made by bonding two or more different materials together with adhesives or other bonding methods. They possess excellent comprehensive properties, such as lightweight, high strength, fire resistance, and corrosion resistance. They are widely used in building structures, interior decoration, furniture manufacturing, and industrial fields, meeting the needs of different environments and functions, and improving the overall quality and service life of buildings.
[0003] Existing composite boards are usually made by gluing and pressing together multiple layers of wood panels. However, the structure of multi-layered wood panels is simple, and sound can easily penetrate the board from both sides, resulting in poor sound insulation and noise reduction. In addition, composite boards are usually fixed with nails to ensure that two boards are fixed close together. At this time, dust can easily enter the joints between the boards, which will affect the use of the composite board. Therefore, we propose a composite board with sound insulation and noise reduction functions. Utility Model Content
[0004] The purpose of this invention is to provide a composite board with sound insulation and noise reduction functions to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a composite board with sound insulation and noise reduction function, comprising a composite board body, wherein a sound insulation layer is provided on the top of the composite board body, the composite board body comprising a first wood board layer, an internal sound insulation board disposed on top of the first wood board layer, and a second wood board layer disposed on top of the internal sound insulation board, wherein the sound insulation layer cooperates with the internal sound insulation board to improve the overall sound insulation and noise reduction effect of the composite board body.
[0006] Preferably, the sound insulation layer includes an external sound insulation board, a plurality of grooves processed on the top of the external sound insulation board, sound insulation cotton fixed inside the grooves, and side pieces fixed to the side wall of the external sound insulation board.
[0007] Preferably, the side member has multiple toothed strips on its sidewall, and the side member has an elongated structure.
[0008] Preferably, the external sound insulation panel has multiple mating strips fixed to its sidewall, and the external sound insulation panel is fixed to the top of the second wooden board layer.
[0009] Preferably, a groove is machined on the right side wall of the wood panel layer, and a protrusion is fixedly connected to the left side wall of the wood panel layer.
[0010] Preferably, a coating sheet is provided on the top of the wood panel layer, and the coating sheet is fitted to the outside of the sound insulation layer.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This utility model incorporates a sound insulation layer on the top of the composite board. Firstly, sound waves from the multiple grooves in the sound insulation layer and the sound-absorbing cotton inside these grooves are refracted onto the cotton when they come into contact with the groove walls. The sound-absorbing cotton absorbs the sound wave energy. Simultaneously, the sound-absorbing properties of the internal sound insulation board further absorb the sound waves, thus achieving secondary noise reduction and sound insulation. This improves the sound insulation and noise reduction effect of common multi-layer wood composite boards and facilitates the installation and use of the composite board.
[0013] 2. When connecting two boards laterally, this utility model allows the protrusion of one board to fit into the groove of the other board, while the toothed strips of the side pieces are staggered. At this time, the sound insulation layer staggered at the top of one board fits into the top of the adhesive sheet of the other board and is fixed by applying adhesive to the adhesive sheet. This allows the sound insulation layer at the top of the two boards to be staggered when they are connected, thereby staggering the gaps between the composite boards and the gaps between the sound insulation layers. This improves the tightness of the connection between the two boards and reduces the amount of dust entering the gaps between the two boards. Attached Figure Description

Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example
[0021] Please see Figures 1-4 The diagram shows a composite board with sound insulation and noise reduction functions, including a composite board body 100. A sound insulation layer is provided on the top of the composite board body 100. The composite board body 100 includes a first wood board layer 101, an internal sound insulation board 102 provided on top of the first wood board layer 101, and a second wood board layer 103 provided on top of the internal sound insulation board 102. The sound insulation layer works in conjunction with the internal sound insulation board 102 to improve the overall sound insulation and noise reduction effect of the composite board. The various structures of the composite board are bonded together using polyurethane environmentally friendly water-based adhesive. The internal sound insulation board 102 is made of common glass wool, which has excellent sound absorption performance and good sound insulation and sound absorption effects.
[0022] Specifically, the sound insulation layer includes an external sound insulation panel 110, multiple grooves 111 processed on the top of the external sound insulation panel 110, sound insulation cotton 112 fixed inside the grooves 111, and side pieces 120 fixed to the side wall of the external sound insulation panel 110. The external sound insulation panel 110 is supported by common foamed plastic sound insulation panels, and the sound insulation cotton 112 is made of polyester fiber with many small pores inside.
[0023] Furthermore, the side member 120 has multiple toothed strips 121 on its sidewall, and the side member 120 has a long strip structure. The side member 120 is made entirely of rubber.
[0024] Furthermore, the sidewall of the external sound insulation panel 110 is bolted with multiple mating strips 113. The external sound insulation panel 110 is glued and fixed to the top of the second wooden board layer 103. The mating strips 113 are stainless steel sheets. The top rear end of the external sound insulation panel 110 has a shallow groove that matches the mating strips 113. When two longitudinal composite panels are connected, the mating strips 113 of the rear composite panel match the shallow grooves of the external sound insulation panel 110 of the front composite panel, which can improve the stability of the longitudinal composite panel connection.
[0025] It is worth noting that the right side wall of the first wood panel 101 is machined with a groove 104, and the left side wall of the first wood panel 101 is fixed with a protrusion 105. When two composite panels are connected horizontally, the groove 104 of the first composite panel is engaged with the protrusion 10 of the second composite panel.
[0026] It is worth noting that a coating sheet 130 is provided on the top of the first wood board layer 101. The coating sheet 130 is used in conjunction with the outside of the sound insulation layer. The coating sheet 130 is made of common synthetic fiber. The bottom of the synthetic fiber is bonded to the top of the second wood board layer 103 using polyurethane environmentally friendly water-based adhesive. Then, common self-adhesive is applied to the coating sheet 130, or glue can be applied to the top of the coating sheet 130 when the two composite boards are connected.
[0027] Working principle: By setting a sound insulation layer on the top of the composite board 100, sound waves from the multiple grooves 111 of the sound insulation layer and the sound insulation cotton 112 inside the grooves 111 are refracted onto the sound insulation cotton 112 when they come into contact with the wall of the grooves 111. The sound insulation cotton 112 absorbs the sound wave energy, and at the same time, the sound absorption characteristics of the material of the internal sound insulation board 102 absorb the sound waves again, thereby achieving secondary noise reduction and sound insulation, thus improving the sound insulation and noise reduction effect of common multi-layer wood composite boards and facilitating the installation and use of composite boards; when connecting two boards laterally, The protrusion 105 of one board can be fitted into the groove 111 of another board, while the toothed strips 121 of the side piece 120 are staggered. At this time, the sound insulation layer staggered on the top of one board will fit into the top of the adhesive sheet 130 of the other board and be fixed by applying adhesive to the adhesive sheet 130. When the two boards are connected, the top sound insulation layer is staggered, thereby making the gap between the composite boards 100 and the gap between the sound insulation layers staggered. This can improve the tightness of the connection between the two boards and reduce the entry of dust into the gap between the two boards.
