Definitions
- the invention relates to the field of production of glued wooden structures and can be used for the manufacture of wall materials, small prefabricated structures, elements of building structures and the structures themselves, suspended and false ceilings, carpentry and furniture panels.
- the utility model considers the construction of a structural wood panel of a lightweight structure having high strength properties and high resistance to bending and torsion.
- Structural materials materials from which various structures, machine parts, and elements of structures that absorb power load are made.
- the determining parameters of such materials are mechanical properties, which distinguishes them from other technical materials (optical, insulating, lubricating, paint and varnish, decorative, abrasive, etc.) (https://ru.wikipedia.org/).
- Wooden lattices are ease of forms, simplicity of design, durability, practicality, versatility.
- wooden gratings are used everywhere as a decorative or finishing material in a wide variety of solutions: on the open veranda, gazebo, porch, as summer cottages and garden fences, pergolas and even in city apartments, where the most ordinary screens for batteries significantly transform the visual perception of the room.
- grilles are also used to decorate furniture facades, cafes, bars, restaurants and other public places.
- the lattice made of natural wood and products made of it organically fit into any interior.
- decorative lattices made of wood perform a number of practical functions: they delimit space, facilitate the creation of volumetric solutions in the interior and exterior, create artificial shading in recreation areas, and act as original screens. Lattice openwork attracts the eye, gives lightness and airiness to any design.
- a lattice wooden building panel which is at least one row of wooden planks equally oriented along the long side and spaced apart, which are interconnected by inserts to form a flat structure between each two adjacent planks is at least one additional element of wood, made with two oppositely located E flat and mutually parallel surfaces, each of which is adhered on one side of one of the two adjacently disposed strips, the wall of said straps on each side adjacent the other are arranged in the general plane (RU147337, ⁇ 04 ⁇ 2 / 00, publ. 10.11.2014). This decision was made as a prototype.
- reinforcing sheet layers in the form of a mesh or web and / or plate material can be glued to the surfaces of the outer walls of a flat structure.
- This feature of the structural design of the building panel provides a sufficient reduction in weight while increasing strength and bearing capacity.
- an increase in strength is achieved either by increasing the number of layers of the lattice panels, or by strengthening the surface layers glued to the lattice structure.
- Reinforcing sheet layers in the form of a mesh or web do not fully solve the problem of increasing the strength and resistance to bending due to the fact that these layers themselves are flexible and flexible, and their strength in the panel is ensured by the adhesive composition.
- the use of plate material in the form of plywood or chipboard or MDF leads to the solution of the problem of increasing resistance to bending stresses and strength, but this leads to a loss of environmental attractiveness, weight increase and, accordingly, the cost of the product.
- the present invention is aimed at achieving a technical result, which consists in increasing the strength characteristics of a structural constructional lattice type panel through the use of high rigidity of the cardboard as surface layers of the lattice structure.
- the structural panel is a flat lattice structure made of wood planks equally oriented along the long side and spaced apart from each other and in which at least one additional element is located between each two adjacent planks made of wood, made with two oppositely located flat and parallel to each other surfaces, each of which is glued on one side of one of the two x said adjacent planks, while at least one outer surface formed by wood planks equally oriented along the long side and spaced apart from each other, a reinforcing sheet layer is glued in the form of a plate material from cardboard intended for operation in an air environment with density from 120 to 2200 g / m with an increase in thickness from 0.25 to 2.0 mm.
- the present invention is illustrated by a specific example of execution, which clearly demonstrates the possibility of achieving the desired technical result.
- FIG. 1 General view of the structural lattice panel.
- a structural wood grating panel is used as a building material and is lightweight at high rates. resistance to bending and torsion and bearing capacity. These indicators determine the operational characteristics of the product, allowing the panel to be used for the manufacture of wall materials, doors, slopes, furniture parts, small-sized prefabricated structures, elements of building structures and the structures themselves, as well as elements of floor and roof coverings, false and false ceilings, joinery and furniture panels .
- this lattice wooden building panel is made of wooden planks 1 (thin long boards or plates) obtained from wood - part of a tree trunk of a certain size and quality, which is the final product of logging production or used as semi-finished products for further mechanical or chemical processing.
- wooden planks 1 thin long boards or plates
- wood planks both commercial wood and low-grade wood can be used.
- additional vkladppey elements you can use even more junk material, sawn knots, etc.
- a lattice wooden building panel in the general case is a flat structure composed of one row of wood planks 1 equally oriented along the long side and spaced apart from each other (or (lamellas glued together, chipboard, MDF, OSB, plywood or wood-containing material ), which are interconnected due to additional elements 2 of wood (can be massive monolithic or glued from lamellas, chipboard, MDF, OSB, plywood) (Fig. 1) or wood-containing material.
- planks 1 there is at least one additional element 2 (insert) made of wood, made with two oppositely located flat and parallel to each other surfaces, each of which is glued one side of one of the two adjacent adjacent strips.
- additional element 2 insert
- the walls of these strips on each other adjacent side are located in a common plane.
- the planks are facing each other with wide sides, and the narrow sides form the outer surfaces. Execution is possible when the planks are interconnected by narrow sides, and the wide sides form the outer surfaces.
- Planks can be rectangular (quadrangular) or square in cross section. The shape of the planks is determined by the technology for producing the planks from a tree trunk or sheet, plate material.
- the rectangular strips 1 are unidirectionally located on the long side and are interconnected by short parts of the same strips.
- Short parts are additional elements 2 in the form of inserts and glued to the strips.
- Additional elements may be arranged in any order: ordered, as shown in FIG. 1, i.e. in a row and each of two opposite sides of a flat structure, either in a checkerboard pattern or in any other order). Additional elements can have different geometry, length and thickness, and their number both in width or thickness, and in length between the strips can also be different.
- laths 1 and additional elements 2 are laid out between them, apply adhesive or adhesive to the contacting surfaces and tighten or compress the entire structure in the direction transverse to the direction of the laths and press it on the plane.
- a force spatially rigid flat structure of increased spatial rigidity and increased resistance to bending and torsion is formed. This is determined by the fact that the gluing of strips with additional elements occurs on a sufficiently developed surface and with the fact that each stripe (for except extreme) has contact with two or more additional elements. That is, each plank through an additional element is a support for an adjacent plank, providing redistribution of local load from one plank to adjacent planks. The longer the additional elements, the more reliable is the connection of the strip with the liner. But this is not critical, since with an increase in the number of inserts it is possible to use short additional elements.
- liners can be used parts of wood, bamboo trunks, composites.
- the insert may be executed with a height equal to the height of the planks, or a height less than the height of the plank, but more than half the height of the plank.
- the liner may be in the form of a cylinder, round or square rings, may have a box-shaped cross-section.
- Liner Essential for the execution of the liner is the presence in it of two oppositely flat and parallel to one another surfaces that are used to apply the adhesive (of any nature, the main thing is that it has adhesion qualities with wood.
- These liners are located between the planks and fasten adjacent planks between forming a rigid single-level spatial structure. Inserts between strips can be located linearly from each edge and between each adjacent pl nkami.
- processing for example, grinding
- grinding After the formation of a flat structure, processing (for example, grinding) of the outer surface is carried out in order to form its flatness and to maintain an equal height of the structure over its entire area from each of its outer surfaces.
- the use of strips with inserts allows you to create spatially developed cellular structures in a given direction, which have high mechanical properties at low weight.
- the structure of the lattice panel accepts loads well in directions that coincide with the direction of the wood fiber, and across these fibers, and this is just the load, transverse to the panel, which allows the panel with this structure to be considered as a building sheet material with high load-bearing capacity.
- Such a panel has a reduced weight, which is determined, in fact, by the weight only of the weight of the slats and inserts. Since after processing the wood and adhesive compositions are practically not affected by aggressive media and do not have elasticity, then after drying of the adhesive or polymerisation of the adhesive, the entire cellular structure is monolithized.
- the thickness of the bar in such structures does not affect the final stiffness and bending resistance.
- the lattice structure is seriously lightened without reducing its strength properties.
- the final spatial rigidity and bending resistance of the cellular system is determined by the configuration of the formed cells and the ability of each individual element to bear the load in conjunction with adjacent structural elements.
- the proposed design of the construction and finishing lattice panel allows to obtain panels of any thickness and structure with low weight, while the design is sufficiently rigid to be used as load-bearing plates.
- the manufacture of lattice structures made of wood is becoming cost-effective and cost-effective, since almost the entire trunk is used as a source material.
- insulating cardboard As electrotechnical cardboard, insulating cardboard “EV” or “EVS” (GOST 2824-86) is used, which is used for electrical insulation when working in air at temperatures up to 90 ° C. Electrical cardboard is also used for the manufacture of patterns in light industry. For covers when stapling documents for archival storage. For documents of long-term storage and everyday use, an electric cardboard is also used, also called electrical cardboard. Electrical insulating cardboard is made in sheets and rolls: roll electric cardboard with a thickness of 0.2-0.5 mm and sheet electric cardboard with a thickness of 0.8; 1.0; 1.5; 2.0; 3.0 mm (see table 1 for strength parameters for different thicknesses of cardboard).
- Electrical cardboard is made on a cardboard machine from 100% cellulose of high chemical purity (ordinary electrical insulating cardboard is made from wood sulfate cellulose and cotton rags to provide increased strength).
- ordinary electrical insulating cardboard is made from wood sulfate cellulose and cotton rags to provide increased strength).
- one of two methods can be used — rolling or calendering. More progressive is the process of compaction of the cardboard by rolling, i.e., by compressing the cardboard with rolling rolls. The process is inherently continuous and lends itself to a maximum degree of mechanization. In the process of compression (pressing) of the cardboard, air is first squeezed out of it, and then partially moisture. The cardboard is deposited and compacted by reducing the capillary space between the cellulose fibers.
- Electrical cardboard is characterized by high density, uniform thickness, smoothness, high mechanical strength, flexibility.
- the surface of the cardboard can be textured (GOST R 53636-2009 “Pulp, paper, cardboard. Terms and definitions”).
- Electric cardboard is used in:
- caseboard Various modifications of the caseboard can also be used, which are marked with signs from “C” to "C-5".
- Each brand of cardboard is distinguished by its technical characteristics, due to which there is the possibility of individual selection, depending on the needs of the packaging manufacturer and the requirements for finished products.
- cardboard is cut into ribbons and wound into bobbins.
- the industry produces sleeve cardboard with a thickness of 0.5 to 0.8 mm in rolls with a width of 700, 840, 1050 and 2100 mm. Due to the high strength of the material, the sleeves made from it are reliable and able to withstand heavy loads when machine unwinding fabric rolls at high speed.
- Coreboard has a density of 170-190 g / m 2 (color-gray, green, brown); 140, 220, 250 g / m 2 (white color).
- a generalizing sign of the choice of cardboard from the whole variety of its types is the thickness and density, which is directly related to the rigidity of the cardboard. Thickness is a variable value, since it depends on the dimensions of the lattice structure. For small dimensions, it is sufficient to use cardboard with a small thickness. And for dimensional panels, cardboard with a thickness of 1 mm to 2 mm. But nothing limits the use of thin cardboard of high density for overall lattice structures. So the parameter is density - 120-2200 g / m 2 and thickness - 0.25-2.0 mm. However, there is a dependence of the density on the thickness of the cardboard, which is expressed as an increase in density from 120 to 2200 g / m 2 with an increase in thickness from 0.25 to 2.0 mm.
- Pasting the lattice design of the panel with sheet cardboard allows you to get a lightweight structural panel with high strength characteristics. At least the plate material is glued to the side surfaces, while the end surfaces remain wooden. Panel pasting is also possible from the end sides.
- multilayer lattice panel structures by superimposing one lattice flat structure onto another with a given offset or at an angle to one another.
- Flat constructions are fastened together by glue or mechanical - dowels, screws, etc.
- the number of cardboard layers on one (and the reverse) side of the lattice structure board may be two or more.
- the outer panel material can also be attached to the surfaces of the outer walls of a flat structure.
- the outer layers pack a flat structure on all sides, forming a building block, protected from moisture and the environment.
- Such packaging can be used not only for multilayer panels, but also for single-layer for the manufacture of furniture, construction and decorative and decorative panels.
- Such multilayer panels are a rigid structure with high bearing capacity.
