Abstract
The utility model relates to a double-solid film H-shaped section bar which belongs to the technical filed of warm house engineering in agricultural installation. The double-solid film H-shaped section bar comprises two flange parts and a web part, wherein the flange parts are clamping groove structures, the web part is formed through connecting two overlapping webs through connecting punched holes in a self-clinching mode, wherein the two flange parts comprise four horizontal lying J-shaped structures, the vertical free ends of the four J-shaped structures are respectively connected with four free-ends of the two webs and form two structures in a shape like the Chinese character 'ji', the structures in a shape like the Chinese character 'ji' are formed through rolling an integral zinc plating plate, and the bended free ends of the J-shaped structures further comprise turning bending parts. The section bar has better functions of resisting rust and corrosion, is more stable compared with a welded girder, has the advantages of time saving and labor saving, and guarantees the integrality of film of a double-layer inflation temperature house.
Description
Technical field:
The utility model belongs to agricultural facility medium temperature chamber field of engineering technology, is specifically related to a kind of two solid film H-shaped material.
Background technology:
Inflatable greenhouse originates from the 1960's U.S., because it has general fractional energy savings about 40%, the highest fractional energy savings reaches 57% obvious energy saving effect, cheap cost and simple structure, promotion and application have worldwide been obtained very soon, in recent years, China is in a large number from the greenhouse of this form of external introduction.
From greenhouse structure, double-deck inflatable greenhouse and monolayer plastic film greenhouse do not have any difference at present, and its main distinction is textural at the solid film of plastic foil.The monolayer plastic film greenhouse generally fixes film with draw-in groove and film-pressing line, and double-deck inflatable greenhouse is without film-pressing line, only fixing around plastic foil, support plastic foil by air pump or fan blower, make the inner plastic film be close to Keelof green house, the outer layer plastic film is isolated by air pressure and inner plastic film, thereby, form air blanketing, produce insulation effect.The solid membrane technology of traditional spring card slot though can fixedly secure plastic film, does not generally reach gastight level yet.
And present double-deck inflatable greenhouse still adopts traditional welded truss structure, and this is perishable with regard to causing whole truss structure and easily becoming rusty because pad is arranged, and need carry out the secondary rust resistance and corrosion resistance and handle.
The utility model content:
At the above-mentioned shortcoming of present double-deck inflatable greenhouse, the utility model proposes a kind of novel section bar that is used for fixing the double-deck mould of inflatable greenhouse.
The purpose of this utility model provides a kind of two solid film H-shaped material.
The technical solution of the utility model is as follows:
A kind of two solid film H-shaped material comprises two edge of a wing portions (1) and a web portion (2), and described edge of a wing portion is the draw-in groove structure, and described web portion (2) is that two overlapping webs connect from riveting via punching.
Above-mentioned two solid film H-shaped materials, wherein the shape of punching can for circular, also can be rectangle in the polygon and rhombus, can also be the two or more combination in circular, rectangle or the rhombus.
In above-mentioned two solid film H-shaped material, in order to make jump ring can be good at blocking plastic foil and can not to be flicked when film is strained, the free end of described draw-in groove structure also can include rotary bending portion.
Above-mentioned two solid film H-shaped material, described two edge of a wing portions (1) comprise four J font structures that couch, and wherein the vertical free end of two J font structures is connected with the free end of described abdomen, forms more than one font structures, and described a few font structures are an integral body; Can replace with other shapes in the J font structure described in the utility model, as [, structure such as ∑, as long as two of this structure match and can constitute the draw-in groove structure and all can be used for the utility model.
The J font structure hook free end of above-mentioned two solid film H-shaped materials also can include rotary bending portion.
The utlity model has following beneficial effect:
1, because the utility model is two blocks of webs to be connected by the mode of punching from riveting at web portion, can not destroy the whole antirust, anti-corrosive of original-pack galvanized sheet, therefore have better antirust, anti-corrosive effect than weldment;
2, owing to adopted structure of the present utility model, make the supporting structure of double-deck inflatable greenhouse keep globality, compare with the truss of welding, more stable;
3, the utility model need not processing steps such as welding, therefore compare with traditional welded truss have save time, the advantage of less manpower;
4, the punching on the utility model web portion can be used as through hole, can several section bars be connected to become an overall structure with other connectors;
5, owing to adopted structure of the present utility model, with traditional interior adventitia is fixed together, the solid membrane technology that separates by fan blower is compared then, when mounted can be separately with interior adventitia, be separately fixed at the both sides of section bar, air-flow can flow between duplicature by the punching of web portion, has guaranteed that the film of double-deck inflatable greenhouse has globality.

1, Fig. 1 is the stereogram of the utility model one embodiment;
2, Fig. 2 is the cross-sectional view of Fig. 1.
The figure number explanation:
1, edge of a wing portion, 11, rotary bending portion, 2, web portion, 21, web, 3, punching.
Embodiment:
For the utility model can better be understood, the utility model is further described below in conjunction with accompanying drawing.
A kind of two solid film H-shaped materials of the utility model, comprise two edge of a wing portions (1) and a web portion (2), described edge of a wing portion (1) is the draw-in groove structure, described web portion (2) is that two overlapping webs (21) connect from riveting by circular punching (3), described two edge of a wing portions (1) comprise four J font structures that couch, the vertical free end of four J font structures is connected with four free ends of two webs (21) respectively, form two a few font structures, described a few font structure is that one whole galvanized sheet is rolling forms, and described J font structure hook free end also contains rotary bending portion (11).
In the present embodiment, in order to make the connection between the two overlapping webs tightr, at circular punching (3) annex some secondary punchings are set and carry out connecting from riveting.
During use, this section bar is combined into supporting structure after, interior adventitia is put in respectively in the edge of a wing portion of last lower bayonet slot structure of this section bar, insert jump ring then, interior adventitia is fixed.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any formal and substantial restriction, all those skilled in the art, in not breaking away from the technical solutions of the utility model scope, when can utilizing the above technology contents that discloses, and a little change of making, modify the equivalent variations with differentiation, be equivalent embodiment of the present utility model; Simultaneously, all foundations essence technology of the present utility model all still belongs in the scope of the technical solution of the utility model change, modification and the differentiation etc. of any equivalent variations that above embodiment did.
