Technical field
The utility model relates to a kind of period composite construction battenboards, belong to the technical field of sandwich manufacture.
Background technique
The concept of period composite construction, also known as phonon crystal, phonon crystal is derived by photonic crystal, in phonon crystal
In, the elastic constant material periodicities different with density arrange, and the material being connected between each other is known as matrix, disconnected
Material is known as scatterer.By the dimension of periodic structure, phonon crystal can be divided into one-dimensional, two and three dimensions crystal, wherein one-dimensional sound
Sub- crystal is generally layer structure, and two kinds of materials are not connected to, and scatterer can not be distinguished strictly with matrix.For two-dimension phonon
Crystal, scatterer is in both direction periodic arrangement, and then scatterer in three directions is in periodic arrangement to three-dimensional phonon crystal.
Studies have shown that in certain frequency leukorrhagia, each scatterer can generate resonance in phonon crystal, with elastic wave phase interaction
With preventing its propagation, this frequency band is referred to as band gap or forbidden band.Since forbidden band frequency is lower, in terms of being suitable for vibration and noise reducing,
And there is biggish application prospect in this regard.
As described above, the forbidden band characteristic of period composite construction provides one kind newly for the vibration isolation and vibration control of engineering structure
Thinking, such as by period composite construction be placed in the propagation path of vibration or using period composite construction thought design structure
Itself, to prevent the vibration in special frequency channel from propagating in the structure, realizes the vibration isolation function of structure；Or it is special using its defect state
Property, the propagation path of vibration is designed, realizes the manipulation to vibration.Therefore, period composite construction subtracts vibration isolation and vibration in engineering structure
Dynamic control field has highly important application value.
Summary of the invention
Technical problem: the purpose of the utility model is to provide a kind of period composite construction battenboard, which is conducive to
Engineering structure subtracts vibration isolation and vibration control.
Technical solution: a kind of period composite construction battenboard of the utility model is by top plate and bottom plate and is located at top plate and bottom
Column period composite construction composition between plate, arrangement mode of the column period composite construction between top plate and bottom plate is the period
Property arrangement mode or relaxed periodicity arrangement mode, or according to vibration control needs, arranged in periodic arrangement or relaxed periodicity
On the basis of defect is set.
Wherein:
Periodic arrangement mode or relaxed periodicity arrangement of the column period composite construction between top plate and bottom plate
Mode is rectangular arranged or hexagonal array mode.
Between the top plate and bottom plate, other than column period composite construction, complementary space can be air, or fill out
Fill foam or concrete material.
The column period composite construction is Nian Jie, bolt or welding manner with the connection type of top plate and bottom plate.
The material of the top plate and bottom plate includes steel, aluminium, concrete or fibre reinforced composites.
The column period composite construction is formed by stacking by the nonwoven fabric from filaments of two or more material, each nonwoven fabric from filaments edge
It is vertically arranged by material in periodic arrangement or relaxed periodicity, the material of adjacent two layers is not identical.
The shape of the nonwoven fabric from filaments is round, rectangle or hexagon or other geometries, and every layer of shape can phase
With can also be different, the number of plies and every layer height can be determine according to actual needs.
The nonwoven fabric from filaments includes steel, silicon rubber or fibre reinforced composites.
Connection in the column period composite construction between each nonwoven fabric from filaments is bonding, bolt or welding.
By each nonwoven fabric from filaments in column period composite construction in vertical periodic arrangement and column period composite construction
Periodic arrangement between roof and floor, the battenboard all have the characteristic of period composite construction in three directions.Vertical each
Nonwoven fabric from filaments forms vertical one-dimensional period composite construction by periodic arrangement；It is compound by the column period horizontal and vertical
The periodic arrangement of structure forms two-dimension periodic composite construction.Therefore, which, which can utilize, utilizes period composite construction
Forbidden band characteristic and directional induction characteristic control the Vibration propagation in three directions, and that realizes structure subtracts vibration isolation and vibration control
System.
The utility model has the advantages that compared with prior art, the utility model has the advantage that
1) it carries out subtracting vibration isolation with the battenboard and vibration control only needs battenboard itself, do not need to add other knots
Structure.
2) dynamic characteristic of battenboard can be controlled by the material and arrangement of column period composite construction, will not
Destroy the connectivity of battenboard and other structures.
