Abstract
The present invention adds steel bars into wooden or non-wooden material and produces artificial ribbed timber through further adhering and pressing. The method can improve the physical and mechanical performance of timber and provides one kind of light high-strength struture material for building industry.
Description
The present invention relates to a kind of composite artificial wooden and preparation method, belong to wood processing field.The disaster that earthquake brings to the mankind is huge, also forces the mankind to seek the building structure material of high-strength light simultaneously.Building structure commonly used has three major types, i.e. reinforced concrete structure, steel construction, timber structure.Preceding its member dead weight of two kinds of structures is big, and heat-insulating property is poor.Though the rod spare that timber structure is used is comparatively ideal material, but the tensile property of timber own is low, node connection place local weakening bar area is serious, moreover China's Forest Resources is serious deficient general, can be developed to timber structure is not had.
The objective of the invention is to utilize in wooden or the non-wooden material and add reinforcing bar, become the imitation wood of arrangement of reinforcement through adhering and pressing, therefore remedied the defective of the single material of timber, improved the physics and the mechanical property of timber, a kind of building structure material of light-high-strength is provided.
Realization of the present invention is finished by following technical scheme:
At first will need fixed length by top layer and sandwich layer or quantitatively, brushwork adhesive is mated formation respectively then, gives being pressed into top layer and sandwich layer blank through finished wooden or non-wooden material.Meanwhile reinforcing bar blanking on demand and colligation are shaped.After with the top layer blank, shaping reinforcing bar and sandwich layer blank are mated formation on backing plate or in the mould in order, put into press hot pressing or cold moudling.
The processing of wooden or non-wooden material is meant Veneer Cutting, the processing of particle, fiber, the peeling of the stalk core of emedullating, and the peeling of salix monogolica rolls etc., and these are prior art, just repeat no more here.
The top layer general thickness is between 1-10MM, and unit weight is at 600-110KG/M
3Between, the wood materials on top layer has veneer, wood fibre, particle, shrub branch (as salix monogolica).There is stalk (as Sunflower Stalk) in non-wooden material.The protection reinforcing bar is generally played on the top layer, is not subjected to the direct corrosion function of air, and the top layer base is suppressed 4-6min and obtained under 1MPa-15MPa pressure.The wood materials that is suitable for sandwich layer has veneer, fiber, particle, shrub branch.There are stalk, bamboo wood in non-wooden material.Generally between 20-1000MM, unit weight is at 400-1000KG/M for core layer thickness
3Between, the generally compacting 4-20min acquisition under 1MPa-10MPa pressure of sandwich layer blank.The glue that is applicable to table, sandwich layer has Lauxite, phenolic resins, certainly other glue kind that also can adopt wood-based plate to use.Reinforcing bar all need eliminate rust, and shape can be formed with colligation or weldering in its connection place.The table base must even brushing one deck glue identical with blank before stacking with core base contact-making surface.This is identical with glued board, particieboard hot pressing or cold-press process as for hot pressing and cold-press process, belongs to routine techniques, also repeats no more here.
Advantage of the present invention is to have added reinforcing bar in sham wood, thereby has improved the physics and the mechanical property of timber, for building industry provides a kind of high-strength light structure material material.

By embodiment feature of the present invention and other correlated characteristic are done further narration below in conjunction with accompanying drawing:
Embodiment 1:
Show as Fig. 1,2,3, to remove the peel, it is long that the Sunflower Stalk bar of core and flattening-out of emedullating is cut into 2000mm, it is 10% that drying makes its moisture content, weigh up respectively and be used for top layer and sandwich layer stalk bar 0.22Kg and 10.6Kg, behind the brushing Lauxite top layer stalk bar is stacked on billet by the 60mm width, put into press room temperature under 2.5MPa pressure 6min that colds pressing, make top layer base (1).In addition sandwich layer stalk bar is stacked and mat formation in the wide channel mould of 60mm, vertically pressurization in mould then at the 2MPa room temperature 10min that colds pressing, is made sandwich layer base (2).2000mm and 50mm are long respectively 3 with being cut into respectively after the rust cleaning of Φ 4 reinforcing bars, become net sheet (3) with the colligation of 22# galvanized wire.Brushing one deck Lauxite on top layer base (1) again, subsequently in order with top layer base (1), net sheet (3), sandwich layer base (2) is put into the wide mould of 60mm, send in the hot press, in 145 ℃ of temperature, exert pressure, make blank be compressed to finger gauge 150mm pressurize 150min when thick, obtain 2000 * 60 * 150mm arrangement of reinforcement flitch.Can be used as wooden frame.
Embodiment 2:
The difference of present embodiment and embodiment 1 is that raw material are board using poplar board, and all the other are all with embodiment 1.
Embodiment 3:
Show that as Fig. 3,4,5 difference of present embodiment and embodiment 1 is to have increased last table base (4) and upper reinforcement (6), the raw material of sandwich layer base are salix monogolicas.Salix monogolica is removed the peel, through rolling in flakes, dry moisture content is 8%, in the Lauxite glue, soak 20min, control after pulling out do not flow to glue till, after put into the inherent 60 ℃ of dry 40min of temperature of baking oven, make its moisture content less than 12%, after make core base (5), all the other all obtain the arrangement of reinforcement flitch with embodiment 1.Can make pin uses.
