Abstract
The utility model provides a corn stalk section bar constitutes its characterized in that by top plate, intermediate lamella and lower plywood: top plate, intermediate lamella and lower plywood are the corn stalk board. Middle plate holder establish the top plate with down between the plywood, the front end of intermediate lamella stretches out the top plate and the preceding terminal surface that descends the plywood, forms the recess between the rear end of intermediate lamella and top plate and time plywood. The top plate comprises multilayer corn stalk, scribbles between every two layers of adjacent corn stalk and is equipped with the tie coat, and two layers of corn stalk that the tie coat will correspond bond together. The intermediate lamella is with the plywood is structurally the same with the top plate down. The tie coat adopts glue for building nontoxic, and PVP glues. The utility model discloses the wall body cavity position that can be used to building frame construction fills usefulness, has light in weight, effectual at a distance from cool heat and sound isolation, reduces the architectural construction, and makes corn stalk obtain make full use of.
Description
Technical field
The utility model relates to a kind of section bar, particularly relates to a kind of special-shaped section be made up of maize straw.
Background technology
China is large agricultural country, and corn is one of China three generalized grain, and its stalk annual production 2.7 hundred million T, accounts for 40% of agricultural crop straw, at present, only has a small amount of maize straw effectively to utilize.
At present, maize straw utilizes and mainly contains following several mode:
1, straw chopping and returning;
2, the raw material producing edible mushroom is used as;
3, be used as to produce marsh gas raw materials;
4, blue or green storage, makees feed;
5, for the preparation of ethanol, etc.
But, the utilization of stalk is also insufficient, and a large amount of maize straw is wasted, in recent years, along with the raising of production estimation level and multiple crop index, and crops economic situation, the improvement of life of farmers quality, the absolute excess phenomenon of stalk is more outstanding, peasant no longer assigns stalk as main fuel, cause a large amount of agricultural crop straw to be discarded in field, even in farmland one, fire is burned, pollute air ambient, easily initiation fire and initiation traffic accident, be detrimental to health.In addition, burning straw makes surface temperature raise rapidly, can directly burn to death, the beneficial microbe scalded in dead soil earth, affects the abundant absorption of crop to soil active ingredient, directly affects the raising of crop yield and quality.
Utility model content
The purpose of this utility model, is to provide a kind of maize straw section bar, can be used for the body of wall hollow part filling use of building frame structure, has lightweight, effective every cool heat-insulating sound-insulating, reduces Architectural Construction, and maize straw is fully used.
The technical scheme adopted is:
A kind of maize straw section bar, is made up of top plate, intermediate plate and lower plywood, it is characterized in that: top plate, intermediate plate and lower plywood are maize straw board.Intermediate plate is folded between top plate and lower plywood, and the front end face of top plate and lower plywood is stretched out in the front end of intermediate plate, the rear end of intermediate plate and form groove between top plate and lower plywood.
Top plate is made up of multilayer maize straw, is often coated with tack coat between adjacent two layers of maize straw, and two of correspondence layers of maize straw are bonded together by tack coat.
Intermediate plate and lower plywood are structurally identical with top plate.
Tack coat adopts nontoxic glue for building, PVP glue.
A kind of maize straw section bar preparation method of the present utility model, by maize straw similar for specification, equal length maize straw material is cut into by setting size, again the maize straw material cut out is laid in mould, on the upper surface of ground floor, PVP environment-friendlyadhesive adhesive (commercial products) is coated after being paved with one deck, form monolithic maize straw board, the method adopting thickness to put upside down makes monolithic maize straw board more smooth.And then on the upper surface of ground floor monolithic maize straw board, take identical way to lay second layer monolithic maize straw board, the rest may be inferred makes maize straw top plate, intermediate plate and lower plywood.Finally maize straw top plate, intermediate plate and lower plywood are pressed Fig. 1 shape ornaments, and be bonded to an overall structure by PVP environment-friendlyadhesive adhesive.
Can be made into the structures such as concave-convex formula, two female, two male, to the needs of filling maize straw section bar during to meet building difformity.
By maize straw cauline leaf partial removal, earth's surface 1.3 is saved the thin partial removal of more than too thick part and corncob and is got stem stalk 3.7 and save Rule section, and availability is probably about 30%.
Maize straw section bar of the present utility model, raw material sources are extensive, and easy to make, cost is low.The utility model is used for the charges between the forward and backward wallboard of building particularly framework integral type building, building is had good in cool, heat insulation, soundproof effect, particularly reduce the cost of building, and make maize straw obtain good application, be conducive to improving the ecological environment, there is very important Social and economic benef@.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
A kind of maize straw section bar, is made up of top plate 1, intermediate plate 2 and lower plywood 3, it is characterized in that: top plate 1, intermediate plate 2 and lower plywood 3 is maize straw board.Intermediate plate 2 is folded between top plate 1 and lower plywood 3, and the front end face 4 of top plate 1 and lower plywood 3 is stretched out in the front end of intermediate plate 2, the rear end of intermediate plate 2 and form groove 5 between top plate 1 and lower plywood 3.
Top plate 1 is made up of multilayer maize straw 6, is often coated with tack coat 7 between adjacent two layers of maize straw, and two of correspondence layers of maize straw are bonded together by tack coat 7.
Intermediate plate 2 and lower plywood 3 are structurally identical with top plate 1.
Tack coat 7 adopts nontoxic glue for building, PVP glue.
