Plate structure
A panel structure and panel body technology, applied to building components, sound insulation, etc., can solve the problems of weakening the sound insulation ability of the space enclosed by the panel, the weakening of the sound insulation ability, and the bending wave, which is called bending wave.

Problems solved by technology
[0003] However, since natural wood is more prone to dry shrinkage and moisture expansion than other materials, when the board body is made of natural wood, since the core material and the board body are fixed to each other, deformation of the board body leads to deformation of the core material, and subsequently, the entire board deformed
As a result, cracks in the body of the panels and gaps abut the protruding parts of the panels; these cracks and gaps reduce the sound insulation of the space enclosed by the panels
[0004] Since the outer peripheral side of the board is usually fixed to the core material, its disadvantage is that it is prone to a phenomenon called bending wave, in which the vibration transmitted from the center to the outer peripheral side of the board body reaches the fixed outer periphery and then returns to the center, at high The sound isolation capability of the frequency band is inevitably weakened by bending waves

Embodiment Construction
[0026] An embodiment of the present invention will be explained with reference to the accompanying drawings.
[0027] figure 1 A schematic plan view of a soundproof room assembled from the panel structures of this embodiment is shown. figure 1 Among them, a soundproof room 10 includes a plurality of wall panels 12 connected approximately square in plan view, a top panel and a bottom panel, which close the inner space of the soundproof room surrounded by the wall panels 12 from the top and bottom.
[0028] In the following explanation of the wall panel 12 , "inner face" means the inner side surface of the soundproof room 10 and "outer side" means the outer side surface of the soundproof room 10 unless otherwise specified. In addition, "top and bottom" and "right and left" are used to indicate "top and bottom" and "right and left" when the installed wall panel 12 is in front and the soundproof room 10 is viewed from the inside.
[0029] Wall panel 12 includes first and second ...

Disclosed is a plate structure, which can prevent deformation of the whole plate even when the plate body is deformed. Said wall plate comprises an inner faceplate, an outer faceplate and a core plate. Said core plate comprises an inner extrusion part and an outer extrusion part, they are jointed with the outer periphery of the inner faceplate and the outer faceplate, and produce gaps around the outer periphery.
Description
technical field [0001] The present invention relates to a panel structure, and more particularly to a panel structure that does not affect other components even when the panel body is deformed. Background technique [0002] Acoustic rooms and similar rooms are traditionally constructed from a number of connected panels. The board includes, for example, a pair of inner and outer plate-shaped board bodies, and a core material positioned between the board bodies and fixed to the board bodies by an adhesive or the like. The panel body may be formed from natural wood, laminate, particle board, or MDF, and the like, but natural wood is preferred for its natural, airy feel. [0003] However, since natural wood is more prone to dry shrinkage and moisture expansion than other materials, when the board body is made of natural wood, since the core material and the board body are fixed to each other, deformation of the board body leads to deformation of the core material, and subsequen...
