Abstract

The utility model discloses a two-layer inflatable heat-insulating plastic film, comprising a two-layer plastic film, and a fixed form aperture connected with the two-layer plastic film is arranged between the two layers. The two-layer thin film and a plurality of fixed form apertures constitute a plurality of longitudinal bar shape air chambers. While in use, a required length is intercepted with one end closed and the other for inflation. The inflation end is closed after inflation, and the utility model can be used for building booth, domestic animal and fowls house etc. The two-layer inflatable heat-insulating plastic film has the advantages of low cost, temperature protection, good day lighting effect and easy use etc.

Description

Double-deck inflatable insulating plastic pipe film

(1), affiliated field

The utility model relates to a kind of agricultural plastic film.

(2), background technology

Plastic film is widely used in building green house of vegetables, seedling culture shed, livestock and poultry house etc.Existing plastic film is single layer structure mostly.Relatively poor with the heat insulation effect that the booth and the livestock and poultry of single-layer plastic film construction are given up.In the winter time, when sunny, temperature of shed is normal, but at night, temperature of shed can descend gradually, even drops to ambient temperature and be close.In order to address this problem, to hide with insulation materials such as straw screen or mat usually, so not only can increase labour intensity, and improve production cost.Another solution is to increase one deck plastic foil on original plastic foil again, forms double-deck booth.Though this method can be avoided the trouble of strqw cover every night, early morning roller shutter, reduce labour intensity, must form the less air barrier of thermal conductivity factor between the two layers of plastic film, just can reach good heat insulation effect.In order between the two layers of plastic film, to form air barrier, just need two groups of supporting constructions, complex structure, the construction difficulty is bigger, the cost height; Two groups of supports are set, also will have influence on the daylighting effect.

(3), summary of the invention

The purpose of this utility model is to provide a kind of high insulating effect, easy to use, with low cost, double-deck inflatable insulating plastic pipe film that daylighting is effective.

The purpose of this utility model is achieved in that it comprises the two layers of plastic film, is provided with the setting barrier film that links to each other with the two layers of plastic film between the two layers of plastic film.

The utility model can also comprise some architectural features like this:

1, all setting barrier film and two layers of plastic film are perpendicular.

2, setting barrier film and the two layers of plastic film in the middle of being positioned at is perpendicular, and the setting barrier film that is positioned at two layers of plastic film side is skewed.

3, the different side edge of two layers of plastic film has overlap edge.

4, described setting barrier film is equidistant distribution.

5, described setting barrier film is that unequal-interval distributes.

Device of the present utility model is by inside and outside two membranes and be connected in that setting barrier film between the two membranes constitutes.Double-layer films and several setting barrier films are formed several vertical bar shaped air chambers.The effect of setting barrier film is to make two membranes keeping parallelism after inflation, and guarantees that each bar shaped plenum chamber of inflation back is not connected, if indivedual air chamber gas leakage can not influence integral body, is arranged in laminated structure after each bar shaped air chamber inflation.Intercepting Len req during use with end sealing, from other end inflation, will be inflated the end sealing after the inflation, promptly can be used for building booth, livestock and poultry house etc.Device of the present utility model uses the mono-layer propping structure just can build double-deck canopy, builds very convenient.The brooder that uses the utility model to build is identical with common double-deck brooder heat insulation effect, but has better daylighting effect.Owing to have certain fabrication strength and tension force after the inflation, can reduce the density of supporting construction, area hour can reduce or not use support, needn't add straw screen or mat and heat-preserving anti-freezing during use, has simplified working procedure.The utility model is applicable to the insulation and the daylighting of winter vegetable booth, seedling culture shed, livestock and poultry house, also can be used for the warming and sealing in house of northern area in winter, and builds simple and easy insulation garage, field work simple tent etc.It is low to have cost, insulation, advantage such as daylighting is effective, easy to use.

(4), description of drawings

Fig. 1 is the structural representation of first kind of embodiment of the present utility model.

Fig. 2 is the cross section of second kind of embodiment of the present utility model.

Fig. 3 is the cross section of the third embodiment of the present utility model.

(5), specific embodiments

For example the utility model is done description in more detail below in conjunction with accompanying drawing:

In conjunction with Fig. 1, the composition of double-deck inflatable insulating plastic pipe film comprises two layers of plastic film 1,2, is provided with the setting barrier film 3 that links to each other with the two layers of plastic film between the two layers of plastic film.The setting barrier film can be equidistant distribution, also can be that unequal-interval distributes.All setting barrier film and two layers of plastic film are perpendicular.The two layers of plastic film adopts the moulding of same material time processing with the setting barrier film.

In conjunction with Fig. 2, the composition of second kind of embodiment of the present utility model is identical with first kind, but the setting barrier film 3 in the middle of being positioned at is perpendicular with the two layers of plastic film, and the setting barrier film 4 that is positioned at two layers of plastic film side is for skewed.Inflate the rectangular triangle in cross section of the air chamber on both sides, back like this, two the duplicatures overlap joints of being more convenient for, lap-joint also has good heat insulation effect behind overlap joint.

In conjunction with Fig. 3, the composition of the third embodiment of the present utility model is identical with first kind, has overlap edge 5 in the different side edge of two layers of plastic film.Two duplicatures overlap joint back lap-joints that are more convenient for also have good heat insulation effect.
