Description
Technical field
It is the composite board of basal body structure with the bamboo wood material that the utility model relates to a kind of, can be used as uses such as the structural wood of building framework or structural ornament or mining mine timber material.
Background technology
China is lumber consumption big country.Be example with the coal mining industry only, belong to shallow, the underground coal in middle level in the domestic coal resources mostly, adopt tunnel driving formula method to mine usually, this just needs a large amount of supports of using ore pillar material (being mine timber) as the tunnel.The colliery mine timber is had relatively high expectations to density, mechanical strength, the warping resistance of timber, is commonly called as the living slowly broadleaf of " hardwood " usually based on Ru Qinggang, silk chestnut, major part tea etc.The again natural forests that belong to state guarantee of these class seeds more, growth cycle is long, and resource is less.Therefore generally taked at present with steel (as the 11# i iron) make support column, mine timber is made the method that crossbeam makes up " steel column+wooden crossbeam " combination of tunnel framework, with the problem of solution mine timber inadequate resource.Though this method has solved support strength, resource anxiety and ecological protection problem, has improved cost of winning.Have statistics to show, during per ten thousand tons of coals were produced, some area on average needed to use about 3.4 tons of steel and mine timber 4 tons (3.5 cubic metres) at present, and the use cost of steel and mine timber reaches 8: 1, nearly 20,000 yuan of the backing material consuming cost in ten thousand tons of coals production.In addition, steel very easily corrosion and influence application life in the wet environment of down-hole; Timber under long-term water logging and the wet condition also easily goes mouldy equally, has reduced support strength, all needs periodic replacement.Therefore, only coal mining industry is just needed the exploitation substitute products badly, to reduce steel and lumber consumption, saves resource, reduces the pit coal cost of mining.
Bamboo wood is a natural biologic material, characteristics such as have the hardness height, sense of touch is good, wear-resistant and beautiful texture, color and luster be simple and elegant, and bamboo because of grow rapidly, cultivation easily, the source is abundant, with low cost.Scarcity day by day along with world's timber resources, bamboo wood is used for substituting timber more and more, existing at present comprising, be widely used in fields such as building, vehicle, packing, decoration, furniture as many bamboo wood based articles such as bamboo mat plywood, bamboo weaving bamboo plywood, bamboo plywood, bamboo wood laminate, bamboo floors.
The utility model content
At above-mentioned situation, the utility model will provide a kind of bamboo based structures sheet material that can have sufficient intensity, make it can have industry widely/civil applications field.
The utility model bamboo based structures sheet material is a kind of straticulate structure body at adhesive and suppression compacted under, on two side planes of the bamboo wood material sandwich layer basal body structure that extends on the plane, is provided with steel mesh reinforcement casing play and bamboo wood charge level layer structure respectively.Wherein, for improving the utilization rate of bamboo wood, reduce the wasting of resources, and the aesthetic property of assurance sheet material, bamboo wood as surface layer structure, can select the material that the outward appearance texture is perfectly straight and more become regular, attractive in appearance, and sandwich layer collective structure the restriction of too much requirement can be there is no to employed bamboo wood material, the weak point of process, little, inferior bamboo wood can also be used.
In the said structure,, multiple different selection can be arranged as the bamboo wood material of said this sandwich layer basal body structure.For example, can adopt at present common both need not be accurate and loaded down with trivial details machining, also need not knit curtain and weave a mat, with all-cis line as the thin bamboo strips used for weaving deck of sprawling that constitutes the unit, or adopt bamboo mat simple and mechanical or manual processing, even can use the bamboo mat of purchase.This thin bamboo strip laminated timber is that a kind of longitudinal strength is high especially, the structural meterials of good rigidly, and product has significant directivity, its structure proximate in reorganization bamboo or reorganization wood, and is main at present as platform floor, is a kind of good timber substitute products.In addition, with bamboo wood discongest into elongated, be cross-linked with each other and keep the reorganization bamboo of the loose reticular fibre bundle of the original arrangement mode of fiber to constitute the netted bamboo beam material of the reorganization bamboo decks such as netted bamboo bundle of unit, can select equally to use.Be the netted bamboo beam material of reorganization bamboo deck
As the reinforcing bar of steel mesh reinforcement casing play, in the utility model bamboo based structures sheet material, can provide enough transverse strength and longitudinal rigidities, the requirement of strength that has when guaranteeing it as load-bearing and/or structure material.This steel mesh reinforcement casing play generally can use reinforcing bar (for example singlely
Reinforcing bar etc.) constitute, can also use the form of structure such as steel mesh reinforcement body of twining formation with less auxilliary reinforcing bar of diameter and main reinforcement.Wherein to reinforcing bar preferably earlier with carrying out surfacing as materials such as coupling agent or isocyanates sizing materials, guaranteeing and to improve reinforcing bar and in bamboo base material solidification process, avoid being subjected to the damage of strong acid/alkalescence, and can play the effect of enhancing bonding force.
Behind used bamboo wood material impregnation, place mould by above-mentioned lamination layer structure mode, through hot pressing or cold moudling, can become corresponding bamboo based structures sheet material according to the needs that use.
The utility model bamboo based structures sheet material can have the strength/rigidity height, and bearing capacity is big, and characteristics such as long service life are removed and can be substituted mine timber, save outside the timber resources, can be used as other wooden construction product equally and obtain substitute, have expanded the application of bamboo lumber.
Below in conjunction with the specific embodiment of accompanying drawing illustrated embodiment, foregoing of the present utility model is described in further detail again.But this should be interpreted as that the scope of the above-mentioned theme of the utility model only limits to following example.Do not breaking away under the above-mentioned technological thought situation of the utility model, various replacements or change according to ordinary skill knowledge and customary means are made all should be included in the scope of the present utility model.
