Embodiment Construction

[0019] The present invention provides a piano middle plate. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0020] see Figure 1-Figure 4 , the invention provides a piano middle plate.

[0021] The middle plate of the piano includes a solid wood core board 100, two layers of surface boards 200 glued to the solid wood core board and the lower surface respectively, and a panel 300 glued to one of the surface boards; the solid wood core board It is formed by stacking and glueing at least two layers of solid wood panels 110 in sequence; each layer of solid wood panels is formed by a number of rectangular solid wood panels 111 glued on the long sides; ...

Abstract

The invention provides a piano center disc. The piano center disc comprises a solid wood core board, two layers of surface boards which are in glue joint to the upper surface and the lower surface ofthe solid wood core board, and a face board which is in glue joint to one surface board. The solid wood core board is formed through sequential stacking and glue joint of at least two layers of solidwood splicing boards. Each layer of solid wood splicing board is formed by a plurality of rectangular solid wood small boards in a long side glue joint manner. The length directions of solid wood small strips on the adjacent two layers of solid wood splicing boards are mutually perpendicular. The provided piano center disc is reasonable in structure, the machining technology is simple, and deformation can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of piano manufacturing, in particular to a piano middle plate. Background technique [0002] At present, the traditional piano middle plate structure is formed by superimposing and pressing a single-layer solid wood core board and two upper and lower man-made splint boards, and then coating the surface of one of the boards with piano lacquer. Affected by paint tension, temperature, humidity and other factors, the middle plate is prone to deformation and bending. As the carrying platform of the piano playing system, the middle plate will seriously affect the intonation and sound quality after deformation. At the same time, the paint coating on the middle plate will seep down and change color with time, thereby affecting the aesthetics of the piano as a work of art. [0003] It can be seen that the prior art still needs to be improved and enhanced. Contents of the invention [0004] In view of the shortco...
