Abstract

The present invention relates to a sunlight greenhouse without a supporting column, which is composed of a soil-cement thin shell tamping wall, a top beam and a non-toxic transparent plastic film, wherein the top beam is a magensium arch-shaped skeleton, the cross section forms an H shape, and the magensium arch-shaped skeleton is formed by butting more than two magensium members. An arch bottom foot of the skeleton supports on a brick column of a front wall, concrete is poured to make the arch bottom foot and the brick column consolidated together; an arch upper foot supports on preset bricks in a tamping wall, and cement is poured to make the arch upper foot and bricks consolidated in a soil wall. The magensium arch-shaped skeleton is formed by mixing magnesia, magnesium chloride, fly ash, saw dust and oxalic acid, and the mixing ratio is 1: 0.51: 0.39: 0.1: 0.05: 0.003. The present invention has the advantages of firmness, durability, low cost and convenient tillage.

Description

Non-support sunlight greenhouse

The production of development greenhouse by solar heat, can not only on limited soil, obtain high output and benefit, satisfy the our province winter-spring season masses and eat the dish demand, and making full use of surplus rural labor force, change the conventional tillage mode, improve peasant's quality of science and market-economy idea, aspects such as quickening rural prosperity paces all are significant.Oneself reaches 1,200,000 mu present our province vegetable protecting field area, plans to reach 1,500,000 mu in 2000.But the used protection of our province ground job facilities belong to simple and easy greenhouse by solar heat more than 95%, it is poor to be incubated, the operation inconvenience, and the life-span is short, almost all will keep in repair every year, is badly in need of having new facility a kind of reasonable in design, durable in use, cheap to replace.

The existing greenhouse by solar heat structure of our province can be divided two types substantially:

A kind of is simple and easy greenhouse by solar heat, needs to mould the canopy greenhouse with earthen wall purlin formula bamboo-wood structure skeleton, accounts for 95% of existing greenhouse by solar heat, and this greenhouse is subject to the wind and rain etch and destroys, general about about 2 years of service time.Because indoor have a pillar, the operation inconvenience influences illumination, and its greenhouse structure and cost are seen Fig. 7, table 1.

Purpose of the present invention is at the problems referred to above, and the compound method of a kind of cost non-support sunlight greenhouse low, simple in structure and magnesia arched framework member thereof is provided.

Non-support sunlight greenhouse of the present invention comprises greenhouse enclosure wall, non-toxic transparent plastic film and magnesia arched framework more than 6.

1, the greenhouse enclosure wall adopts soil cement shell compacting cob wall.Be about to broken diffusing earth material and a certain amount of portland cement and the even mix of suitable quantity of water is made soil cement.Soil cement is put on the earthen wall of compacting, when hydrated cementitious, then forms the soil cement shell of hard durable.

2, magnesia arched framework is that cross section is I-shaped parabola arch skeleton.Constitute by magnesia member butt joint more than 2.The arch footing of magnesia arched framework is bearing on the brick post of front wall, and cast concrete on brick is consolidated arch footing and brick post.Pin is bearing on compacting the laying bricks in the cob wall on the arch, and cast concrete on brick makes arch go up pin and brick is cemented in the cob wall.For making magnesia arched framework lateral stability, reserve a hole in the first-class distance of magnesia arched framework, and cross to give with reinforcing bar and box out, with iron wire magnesia arched framework and reinforcing bar are tied, prevent arched framework generation lateral displacement.

3, cover overlay on magnesia arched framework upper berth.

Non-support sunlight greenhouse of the present invention does not have pillar, and spacious in the greenhouse, farming is convenient.Particularly magnesia arched framework is sturdy and durable.Non-support sunlight greenhouse not only farming is convenient, sturdy and durable, and cost is low, and is only close with simple greenhouse's cost with scale, helps applying in the rural area (seeing attached list 3).

4, the compound method of magnesia arched framework

Magnesia arched framework is mixed with by magnesia, magnesium chloride, flyash, sawdust, oxalic acid (also acids such as phosphoric acid).Magnesia arched framework cross section is I-shaped parabola arch skeleton.Magnesia is the effective ingredient of utilizing in the magnesia (Mgo), and magnesium chloride is to utilize bittern (MgcL H ₂O) effective ingredient in.The proportioning of the effective content of above-mentioned material is: magnesia: magnesium chloride: flyash: sawdust: oxalic acid (or phosphoric acid)=1: 0.51: 0.39: 0.1: 0.05: 0.003.This magnesia arched framework water logging or insolation be indeformable, do not peel, long service life.

The preparation method of magnesia arched framework is earlier that magnesia and bittern is synthetic, mixes other material again and fully mixes all, after aquation 15-20 minute, can pour into a mould in the arched framework mould, just can use after the moulding.

Fig. 1 is the structural representation of a kind of embodiment of non-support sunlight greenhouse of the present invention, Fig. 2 is a soil cement shell compacting cob wall schematic cross-section, Fig. 3 is magnesia arched framework schematic cross-section, Fig. 4 is 2 magnesia arched framework junction vertical views, Fig. 5 is an arch axis line schematic diagram, Fig. 6 is the permanent greenhouse by solar heat structural representation of brick armored concrete, and Fig. 7 is a band pillar simple greenhouse structural representation.Be described further below in conjunction with the structure of present embodiment no pillar sight greenhouse.

Non-support sunlight greenhouse is made of soil cement shell compacting 1,3 above back timbers 2 of cob wall and non-toxic transparent plastic film 3.Back timber 2 is magnesia arched framework.Soil cement shell compacting cob wall is by smearing 1cm solid cement soil 5 on the two sides of compacting cob wall 4, smearing thick 5cm solid cement soil 6 in the upper surface and constitute.

Several charge ratios of soil cement see Table 4.

The match ratio (table 4) of soil cement

Great soil group	Soil cement match ratio (%)	Remarks
	Earth material cement
	Sandy soil		86　　　　14	Percetage by weight
Loamy soil	82　　　　18
Clay soil	78　　　　22

Wide 80cm on the cement compacting cob wall, following wide 120cm, the long 700cm in greenhouse crouches in underground 40cm, and the above high 200cm in ground is provided with winter protection ditch 8 in the outside of front wall 7.

Magnesia arched framework 2 is that the cross section is I-shaped parabola skeleton, is made up of 2 magnesia members 17,18, and at span centre butt joint steel clamping plate 9, bolt 10 is (see figure 4) fixedly.

The member of magnesia arched framework 2 is mixed with by magnesia, bittern, flyash, sawdust and oxalic acid, and its effective ingredient charge ratio is 1: 0.51: 0.39: 0.1: 0.05: 0.003.

The arch footing 11 of each magnesia arched framework 2 is bearing on the brick post 12 of front wall, and pours into a mould the concrete of going up high 10cm, arch footing 11 is consolidated with brick post 12.Pin 13 is bearing on the brick 14 that presets in the compacting cob wall on the arch, and pours into a mould the concrete of going up 10cm, makes arch go up pin 13 and is cemented in the cob wall with brick 14.In order to make magnesia arched framework 2 lateral stabilities, on magnesia arched framework 2, reserve 3 holes, and cross corresponding preformed hole on each magnesia arched framework respectively with 3 φ, 4 reinforcing bars 15, and with iron wire magnesia arched framework and reinforcing bar are tied, prevent that arched framework from producing lateral displacement.

In addition, on the adverse grade of magnesia arched framework 2, place warming plate 16, and on warming plate, smear the thick soil cement of 5cm, make it to be connected with wall behind the greenhouse by solar heat.Be referred to as short adverse grade.The every wide 65cm of warming plate, long 100cm, thick 8cm.Warming plate is after moulding the plate pulverizing with waste and old polyvinyl chloride foam, to mix magnesium gelatinous material, injects in the film and makes.

On magnesia arched framework, overlay is set at last, just constitutes non-support sunlight greenhouse.
