Description

Biomass-based inclined column type dot matrix sandwich structure

The technical field is as follows:

the utility model relates to a building material field especially relates to a living beings base batter post type dot matrix sandwich structure.

Background art:

at present, forest resources are deficient, and the wood engineering composite material is widely applied to the furniture manufacturing industry, but the application of the wood engineering composite material in the building field is relatively narrow. In some applications where high strength and multiple functions are required, wood engineering composites are less competitive than other building materials. The lattice structure has light weight, high specific strength and high specific rigidity, and the core has high porosity, and may be used in material, structure and function design. Therefore, the lattice structure is applied to the design of the biomass composite material, can meet the requirements of structural bearing and multi-functionalization (light weight, shock absorption, noise reduction, sound insulation and heat insulation), meets the requirements of national development of environment-friendly and resource-saving materials, and has important ecological benefits, economic benefits and social benefits.

The invention content is as follows:

the utility model provides a living beings base batter post type dot matrix sandwich structure is applied to living beings combined material's design with batter post type dot matrix structure in, develops neotype engineering material so that it is applied to fields such as timber structure building, overcomes traditional wooden engineering material dead weight, cost and the not enough of function singleness higher relatively.

The utility model provides a living beings base batter post type dot matrix sandwich structure, its characterized in that living beings base dot matrix sandwich structure includes top panel (1), lower panel (2), batter post type dot matrix sandwich layer (3) comprise a plurality of batter post type dot matrix structure (4), batter post type dot matrix structure (4) have different configurations and adjacent configuration and are the symmetric distribution, top panel (1), lower panel (2), connect through the gluing agent between batter post type dot matrix sandwich layer (3), the bearing capacity and the stability of structure in vertical side have been promoted effectively. A biomass-based inclined column type dot matrix sandwich structure is realized by the following technical scheme:

designing the size and variable parameters of a core layer oblique column type lattice structure, wherein the size and variable parameters comprise the center distance of adjacent drill holes, the drilling depth, the core inclination angle, the core height, the core diameter, the upper panel thickness, the lower panel thickness, the panel length, the panel width, the arrangement direction (horizontal and vertical) of surface layer fibers of an Oriented Strand Board (OSB) and the proportion of an adhesive.

And secondly, sawing the directional shaving board, scribing, drilling, preparing a core, and blending an adhesive to finish the preparation of the part and the adhesive.

And thirdly, assembling the upper panel, the lower panel and the core, connecting the panel and the core through an adhesive, standing the member until the adhesive is solidified, and filling a larger gap of the core layer with a flame-retardant material, an adsorption material, a thermal insulation material and the like.

The utility model has the advantages that:

the utility model discloses in being applied to the structural design of the wooden engineering material of living beings base with batter post type lattice structure, have following advantage: 1. the insertion-gluing method is adopted to prepare the component, so the operation process is relatively easy; 2. the preparation material has wide sources, and various materials and a large amount of reagents are not needed; 3. the assembled test piece can be cured at normal temperature; 4. the upper and lower panels are all oriented strand boards, and the panels and the core layer have better interface compatibility; 5. the core layer is of an oblique column lattice structure, has a large void ratio and provides possibility for filling functional materials; 6. the bearing capacity and the stability of the structure in the vertical direction are effectively improved; 7. the structure meets the national requirements for developing environment-friendly and resource-saving materials.
