[detailed description of the invention]
Below in conjunction with accompanying drawing, the present invention will be described in detail:
Fig. 1 illustrates the schematic three dimensional views of an embodiment of the honeycomb ripple composite construction of the present invention, and this composite construction includes the corrugated plating 3 in top panel 1, four directions honeycomb texture 2, honeycomb and lower panel 4.Observing the internal structure of this embodiment for convenience, Fig. 1 have employed section view method, and has separated cubic honeycomb texture 2 and corrugated plating 3.
Four directions honeycomb ripple composite construction sound absorption loading plate includes top panel 1, corrugated plating 3 and lower panel 4；Corrugated plating 3 is inclined between top panel 1 parallel to each other and lower panel 4, the cubic honeycomb texture 2 of square hole embeds in corrugated plating 3, four directions honeycomb texture 2 upper and lower surface is connected with top panel 1 and lower panel 4 respectively, corrugated plating 3 and top panel 1 all offer sound-absorption hole, sound-absorption hole on top panel 1 is corresponding with four directions honeycomb texture 2 each cellular unit structure, on corrugated plating 3 and top panel 1, sound-absorption hole is coaxial aperture, and perforate direction is and is perpendicular to top panel 1.It is one that corrugated plating 3 strides across the minimum number of cellular unit in the honeycomb texture 2 of four directions.
Composite construction sound absorption loading plate mainly has two pieces of panels and four directions honeycomb texture therein and corrugated plating to combine.One of top panel is evenly arranged sound-absorption hole, and corrugated plating is also uniformly distributed sound-absorption hole.
Sound-absorption hole on described top panel and four directions honeycomb texture one_to_one corresponding, namely each four directions honeycomb texture cell element body all has a sound-absorption hole to communicate therewith.The sound-absorption hole of described corrugated plating is coaxial aperture with the sound-absorption hole on top panel, and perforate direction is and is perpendicular to panel.
The apertured panel of described plate body is towards indoor, and apertured panel is not towards outdoor.So the purpose of design is so that sound can enter plate body, and is partially absorbed.
Preferably, the sound-absorption hole aperture on panel and corrugated plating should be submillimeter level.
The composite plate that the present invention relates to, both can be wooden boards or metallic sandwich sheet is made, or adopted plastics, porous fibre, perforated foams to make.
In embodiments of the present invention, the thickness of top panel 1 is 1mm, and covering thickness is on the upper surface of cubic honeycomb texture 2 of 15mm.Top panel 1 uniformly has the sound-absorption hole that aperture is 0.5mm, in order to allow noise enter composite construction, thus reaching to absorb the purpose of sound.The quantity of opened sound-absorption hole is relevant with the size of each cellular unit in the honeycomb texture 2 of four directions, the corresponding sound-absorption hole of each cellular unit.Four directions honeycomb texture 2 is embedded among the corrugated plating 3 that thickness is 1mm, and the corrugated plating in each cellular unit vertically has the sound-absorption hole of a diameter 0.4mm.Four directions honeycomb texture 2 cavity is filled or unfilled with sound-absorbing porous material.The lower panel 4 that thickness is 1mm covers on the lower surface of four directions honeycomb texture 2.
