Abstract
A composite soundboard used on piano is composed of surficial board, core board and back board, which are coated by adhesive and hot pressed. The thickness of the sound board is 8.2 mm. The core plate is formed by splicing a plurality of same radial-cutting thin plates. The surface plate and the back plate are formed by splicing a plurality of same radial-cutting single plates. When splicing, the included angle between the wood grain of the thin plate (or the single plate) and the length direction of the core plate (or the surface plate and the back plate) formed by splicing is 0-180 degrees. The soundboard with the structure improves the utilization rate of wood, and solves the difficult problems that the original solid wood soundboard is easy to deform, crack and select materials difficultly.
Description
The utility model is the improvement of piano soundboard structure.
Piano soundboard adopts individual layer thin plate splicing of the same race to form at present.The soundboard materials of this structure require very strict, and defectives such as knot, bark pocket mustn't be arranged, and the annual rings of timber spacing that requires materials is at the 2-5 millimeter, and texture is perfectly straight, and color and luster will be near consistent, and splicing is tight.Because quality requirements is very strict, selection is just very difficult, and the utilization factor of timber is also just very low naturally.This solid wood soundboard by thin plate splicing is after moisture absorption or losing moisture content, and yielding or cracking has seriously influenced the piano quality.
The purpose of this utility model provides a kind of piano Complex soundboard of new construction.
The purpose of this utility model is achieved in that the piano Complex soundboard by 3 three layers of compound composition of dash board 1, central layer 2, backboard, scribbles bonding agent between every layer, and is hot-forming; Soundboard thickness is at 8-8.2MM.Central layer adopts polylith quarter sawing thin plate 4 of the same race to be spliced; When thin plate and thin plate splicing, it along the grain 5 presses same angle splicing.The angle that thin plate along the grain splices and the central layer length direction angle that is spliced are in 0-180 degree scope; Bonding agent is adopted in splicing.Dash board and backboard adopt polylith quarter sawing veneer splicing of the same race to form respectively; During splicing, veneer along the grain 5 by the splicing of same angle, with the dash board that is spliced and backboard length direction angle in 0-180 degree scope; Splicing adopts masking tape to heat bonding.The specification of soundboard is pressed the specification of piano and is decided.
The utility model has adopted dash board, central layer and backboard three-layer composite structure, and central layer can the employing timber different with dash board and backboard during production, and when especially central layer was selected materials, the color and luster of timber can not done requirement, and the annual ring of timber requires to expand 1-8MM to; And have the sheet material of defectives such as slight knot, scar after repairing, also can utilize, improved the utilization factor of timber so widely.This composite structure has solved that former solid wood soundboard is yielding, the difficult problem of cracking, difficult selection.The utility model against weather is good, and humidity is indeformable, does not ftracture, and has improved the piano quality, has widened timber materials kind.
The utility model is provided by following examples and accompanying drawing thereof.

Fig. 2 central layer splicing synoptic diagram
1 dash board, 2 central layers, 3 backboards, 4 thin plates, 5 wood grains
The utility model scribbles urea-formaldehyde glue by 3 three layers of compound composition of dash board 1, central layer 2, backboard between every layer, hot-forming; Soundboard thickness is at 8.2MM.Central layer adopts polylith quarter sawing thin plate 4 of the same race to be spliced, and thin plate can be selected fish-scale floss, linden or Korean pine for use.The central layer specification can require according to the difference of piano to decide.When thin plate and thin plate splicing, it is along the grain by same angle splicing.The angle that thin plate along the grain splices and the central layer length direction angle that is spliced are in 0-180 degree scope; Bonding agent is adopted in splicing.Dash board and backboard adopt polylith quarter sawing veneer splicing of the same race to form respectively; During splicing, veneer along the grain 5 by the splicing of same angle, with the dash board that is spliced and backboard length direction angle in 0-180 degree scope; Splicing adopts masking tape to heat bonding.
