Abstract

The utility model relates to a greenhouse frame without a support prop, which is composed of two parallel upper chord frames, two parallel lower chord frames, and a middle garland component. The garland of the middle garland component forms a triangle shape; the triangular upper fulcrum and the triangular lower fulcrum of the triangular garland which are welded fixedly are respectively clamped between the two parallel upper chord frames and the two parallel lower chord frames; the diameter of the steel bars of the upper chord frames, the lower chord frames, and the middle garland component are between 6 to 8 mm. A greenhouse without the support prop can be built by adopting the utility model which has the advantage of high durability, and the cost is only slightly higher than the greenhouse with a same size and simple bamboo and wood structure.

Description

No pillar Keelof green house

The utility model relates to a kind of skeleton of making no pillar plastic cover greenhouse, particularly covers the Keelof green house of double-deck overlay.

Along with further going deep into of reform and opening-up, living standards of the people improve rapidly, and the northerner also will eat various fresh vegetables in the winter of cold, and the cities and towns people's life has not only been enriched in the production of warmhouse booth, has also improved vegetable grower's income.The support of present existing warmhouse booth mainly contains two classes, and a class is easy bamboo-wood structure, and another kind is a bar construction.Easy bamboo-wood structure, pillar stands in great numbers, and shading is serious, and durability and soundness are all very poor, every circuitous driving snow, the peasant worries very much.And the warmhouse booth of the permanent type bar construction that adopts at present, reinforcing bar beam heaviness (more than the every 20kg), the cost height, though without pillar, the illumination performance is good, common vegetable grower can not build.

The purpose of this utility model is to provide a kind of in light weight at the problems referred to above, and cost is low, robust no pillar Keelof green house.

The purpose of this utility model adopts following technical proposals to realize, that is:

No pillar Keelof green house is the semi-arched skeleton, is made up of the beam that winds up, lower edge fine strain of millet and middle garland member, and the fine strain of millet of winding up is made up of 2 skeletons that wind up side by side, and the lower edge beam is made up of 2 lower edge skeletons side by side.Middle garland member is made garland triangular in shape by the reinforcing bar welding.The upper and lower triangle fulcrum of middle garland member is clipped in respectively in the middle of 2 wind up skeleton and 2 lower edge skeletons side by side side by side, and solid welding connects.2 skeletons that wind up, 2 lower edge skeletons and make in the middle of the diameter of reinforcing bar of garland member be φ 6-8mm.

The no pillar Keelof green house of this structure, integral rigidity is good, and it is strong to bear pressure capability, (about every 10kg) in light weight, cost is low.Build plastic greenhouse without pillar with the utility model, the illumination performance is good, and cost is slightly higher than the plastic greenhouse of simple and easy bamboo-wood structure, but durability and soundness are considerably beyond simple and easy bamboo-wood structure greenhouse.The utility model helps the transformation of old simple and easy bamboo wood plastic greenhouse.Transform the plastic greenhouse of simple and easy bamboo-wood structure, can keep the back wall and the adverse grade of former booth, only need column be set at the front end of adverse grade and get final product, all the other places just need not be provided with column.In addition, the utility model is highly suitable for laying overlay on wind up skeleton and lower edge skeleton, promptly double-deck the covering, and this plastic greenhouse is good heat insulating not only, and the illumination performance might as well.

Fig. 1 is a kind of user mode schematic diagram of the present utility model, and Fig. 2 is a structural representation of the present utility model, and Fig. 3 is the vertical view of Fig. 2, and Fig. 4 is the A-A view of Fig. 2, and Fig. 5 is middle garland element structure schematic diagram.The utility model is described in further detail below in conjunction with accompanying drawing.

No pillar Keelof green house comprises the skeleton 1 that winds up, the skeleton 2 that winds up, lower edge skeleton 3, lower edge skeleton 4 and middle garland member 5 constitute.The reinforcing bar 6 that middle garland member 5 is φ 6mm by 3 above diameters is welded into the triangle garland.Wind up skeleton 1 and wind up skeleton 2 side by side, lower edge skeleton 3 and lower edge skeleton 4 are side by side.Fulcrum 7 all is clipped in the skeleton 1 and winding up between the skeleton 2 of winding up on all triangle of middle garland member 5, and welds together with the wind up skeleton 1 and the skeleton 2 that winds up.All triangle lower fulcrums 8 of middle garland member 5 all are clipped between lower edge skeleton 3 and the lower edge skeleton 4, and weld together with lower edge skeleton 3, lower edge skeleton 4.The bar diameter of skeleton 1,2 and

lower edge skeleton

3,4 of winding up is φ 8mm.

Claims

1, no pillar Keelof green house is made of the beam that winds up, lower edge beam and middle garland member (5), it is characterized in that:

A, the beam that winds up are made up of skeleton that winds up (1) side by side and the skeleton that winds up (2), and the lower edge beam is made up of side by side lower edge skeleton (3) and lower edge skeleton (4);

B, the triangle garland of middle garland member (5) for being welded into by 3 above reinforcing bars (6);

Fulcrum (7) all is clipped between skeleton that winds up (1) and the skeleton that winds up (2) on all triangle of C, middle garland member (5), and solid welding links together, the all triangle lower fulcrums (8) of middle garland member (5) all are clipped between lower edge skeleton (3) and the lower edge skeleton (4), and solid welding links together.

2, the described no pillar Keelof green house of root a tree name claim 1 is characterized in that the bar diameter of the described skeleton that winds up (1), the skeleton that winds up (2), lower edge skeleton (3), lower edge skeleton (4) and middle garland member (5) is φ 6-8mm.
