Abstract
A sandwich plate with polygonal lattice in middle area can be applied to the intensity strengthening structure for various industrial products. The sandwich plate comprises an upper sandwich, a lower sandwich and a lattice wall. The utility model is characterized in that the joints of each lattice wall are provided with strengthening columns along the lattice wall between the upper sandwich and the lower sandwich. The utility model effectively reduces the stress concentration, greatly improves the compressive strength, meanwhile improves the wind resistant intensity and the anti-stripping intensity between the upper sandwich and the lower sandwich, finally the sandwich structure with light weight and high intensity can be received. The sandwich plate with polygonal lattice of the utility model can be widely applied to the field from common packing material to the aerospace supplies.
Description
Technical field
The utility model relates to a kind of sandwich plate, relates in particular to the sandwich plate that a kind of centre is a polygonal gird.
Technical background
The honeycombed structure is placed between the two boards, be widely used in industry to reach structure in light weight, the high strength ratio, it can keep overall construction intensity preferably when reducing the use material.But existing honeycombed structure also is not a kind of optimized reinforced structure, all still has sizable improvement potentiality at aspects such as ability of bearing the ability of pressure, opposing distortion and the opposing of the interlayer in fluctuate interlayer peel strengths thereof.The present invention gains enlightenment by the dissection to the beetle fore wing from bionic angle, and having invented a kind of centre is the interlayer reinforced structure with pillar core of polygonal gird, is used for behind the industrial products its structural strength being improved greatly.
Summary of the invention
The purpose of this utility model provides the sandwich plate that a kind of centre is a polygonal gird, is applicable to the structural strength of strengthening various industrial products and reduces material consumption.The technical scheme of this utility model is that a kind of centre is the sandwich plate of polygonal gird, comprises train wheel bridge, lower plate, cell walls, it is characterized in that being provided with reinforcing prop along the intersection of cell walls.The distribution of described reinforcing prop in a polygonal gird construction unit can be one or a few, but smaller or equal to polygonal limit number, the two ends of reinforcing prop are provided with the boss that is slightly larger than the reinforcing prop diameter, be connected by rounding off between boss and reinforcing prop, the clamping plate, described polygonal gird structure can be the regular hexagon grid, also can be other polygonal gird.Interlayer is closely to be arranged by the polygonal gird of a plurality of hollows to form, honeycomb arrangement is a kind of hexagonal grid structure wherein, reinforcing prop can be according to different structural materials with the coupling method between the fluctuate interlayer, and methods such as employing is weaved, weaving, adhesion are made.Upper and lower clamping plate can be dull and stereotyped, also can be curved slabs.
The sandwich plate that manufactures with said structure, compare with the cellular sandwich plate that does not have reinforcing prop, can improve the peel strength between the compression strength of sandwich plate, anti-twist intensity and fluctuate interlayer greatly, and can reduce stress effectively and concentrate, be a kind of in light weight, biomimetic features sandwich material that intensity is high, have a wide range of applications to the Aero-Space equipment from common packaging material, construction material.

The specific embodiment
Below in conjunction with accompanying drawing the embodiment of this utility model is described, the structural representation of the utility model embodiment and intermediate course structural representation are respectively as shown in Figure 1 and Figure 2.This sandwich plate is made up of last lower plate 1,6 and intermediate course, last lower plate 1,6 is dull and stereotyped, intermediate course is that tight arrangement of cellular orthohexagonal grid forms, and the junction of per 3 orthohexagonal cell walls 2 is equipped with a reinforcing prop 3, as shown in Figure 2.Reinforcing prop 3 two ends respectively are provided with a boss 5, and 5 one end faces of boss are plane 4, are convenient to upper and lower clamping plate 1,6 bondingly, and boss 5 other ends are connected with reinforcing prop 3 cylinder smooth transition, as shown in Figure 3.Closely be connected between reinforcing prop cylinder and each cell walls, and form an integral body with orthohexagonal alveolate texture, method that lower plate 1,6 can be by adhesion on it and cylinder bottom end face 4 and cell walls 2 are connected and fixed, and can finish the processing of sandwich plate.
In the above-described embodiment, its manufacture method of different materials is also slightly different, as uses plastics, and available mould adopts integral injection molding method to be shaped; As use fibrous material, can adopt hatching to be shaped; As use metal material, the method that available adhesive approaches and punching press combine is shaped.
The polygonal gird structure of hollow described in the utility model is not limited to orthohexagonal alveolate texture, and this lattice structure also can be equilateral triangle, square structure, and their structural representation is respectively as (a) among Fig. 4 (b) shown in (c).In an orthohexagonal alveolate texture unit, the reinforcing prop number can be 1～6.The cellular construction of other n limit shape and the like, promptly the number of its reinforcing prop should be 1～n.The planform of reinforcing prop 3 various kinds that also makes preparations for sowing, commonly used has: the cylinder two ends have boss, be several types such as hollow and solid in the cylinder.Respectively as (a) among Fig. 5 (b) shown in (c).
