Abstract

The invention provides a method for laying bilaminar membrane booth and the used supporting cushion, solving the problem of bad thermal insulation effect of the monolayer film booth and high cost of replacing the booth membrane with sun board. The laying method are: (1) constructing booth frame; (2) laying inner booth membrane on the arch centering upper boom, and fixing preliminarily,; (3) fixing the supporting cushion on the inner membrane; (4) laying outer membrane on the supporting cushion and fixing preliminarily; (5)tightening the squeeze membrane line on the outer booth membrane, and fixing the booth membrane. The active effects of the invention are: the thermal insulation effect is improved greatly because of the two booth membrane; the thermal insulation effect is not worse than the sun board but the cost is lower than it; comparing with the inflatable bilaminar membrane, the implement is convenient; cost is low and is easy to be spreaded.

Description

A pad of the laying method of double-deck canopy film booth and use thereof

Technical field

The present invention relates to the laying method of a kind of agricultural, particularly a kind of laying method of double-deck canopy film booth with the plastic greenhouse film booth.

Background technology

Booth has just demonstrated huge superiority since being born, booth is adopted in increasing area, and increasing peasant has gone on the road of affluence by booth.Present booth mainly is by the canopy framework and lays the canopy mould constitute on framework.The canopy film is the daylighting heat collector surface, is again radiating surface.By the heat that the canopy film distributes, account for the 73-80% of the total heat dissipation capacity of booth.Because the loss of a large amount of heats, in the severe winter canopy, can occur hazing, condensation, frosting even icing phenomenon.No matter this phenomenon is to plant husbandry, aquaculture or as the place of activity in production, all is very disadvantageous.For this reason, for a long time, people have thought that thousand and one way solves this problem, such as also making solar panel replace the canopy film with the double-deck lucite of hollow type.Because the double-deck lucite price of hollow type is too high, the peasant can't accept; Also have a kind of method, double-deck canopy film through being hot pressed into the strip air flue, is inflated in the strip air flue again, reach heat preservation effect.This method at first will guarantee the quality of canopy film, for a long time need be air tight under high pressure conditions, and secondly be that construction is complicated, be the daylighting reduction at last, also unfavorable popularization.

Summary of the invention

The object of the present invention is to provide the laying method of the double-deck canopy film booth of a kind of with low cost, easy construction, good heat preservation performance.

Technical scheme of the present invention is:

One, the laying method of double-deck canopy film booth is:

1, builds the booth framework.If greenhouse by solar heat, framework comprises the bow member on three enclosure walls and the enclosure wall; If simple plastic greenhouse, then framework is exactly a bow member;

2, on the winding up of bow member, lay nexine canopy film, and preliminary fixing;

3, fixing pad on nexine canopy film;

4, on a pad, lay outer canopy film, preliminary fixing;

5, film-pressing line is tightened, be pressed on the outer canopy film, the canopy film is fixed.

Two, above-mentioned pad can be following any:

1, props up pad and be honeycombed.

2, propping up pad is that section is the section bar of trough of belt.

The pad material can select for use foamed rubber-plastic, foamed plastic, silicon rubber, three none fourth glue etc. any.

When elected honeycombed is propped up pad, whole pad can be clipped between nexine and the outer field canopy film.

Elected section is that the section bar of trough of belt props up when pad, on the winding up of bow member, lay nexine canopy film after, the groove of this pad is buckled on the winding up of bow member, on the pad that more outer canopy film is laid in, be pressed on the pad with film-pressing line.

The present invention compares with monofilm, owing to implemented two-layer canopy film, heat insulation effect improves greatly; Compare with solar panel, heat insulation effect does not reduce, and cost reduces greatly; Compare with inflatable double-layered canopy film, it is convenient, with low cost to implement, and is easy to popularize.

Embodiment

Embodiment one: double flute shape is propped up the double-deck canopy film booth of pad

The laying method of double-deck canopy film booth is:

One,, builds the booth framework referring to Fig. 1,5,6.If greenhouse by solar heat, framework comprises the bow member 1 on three enclosure walls 2 and the enclosure wall, if simple plastic greenhouse, then framework is exactly a bow member 1;

Two, lay nexine canopy film 3 winding up of bow member on 1.1, and preliminary fixing;

Three, Fixed Sections is that double flute shape section bar props up pad 4 on nexine canopy film 3, and its section can be dumb-bell shape (referring to Fig. 3), can also be X-shaped (referring to Fig. 4).Form on this pad two back-to-back on groove and following groove.The following groove of this pad is buckled in winding up on 1.1 of bow member 1.

Four, on this pad, lay outer canopy film 6, preliminary fixing;

Five, film-pressing line 5 is tightened, be pressed in the last groove of this pad, the canopy film is fixed.

Embodiment two: single flute profile is propped up the double-deck canopy film booth of pad

Referring to Fig. 2,6, not existing together with embodiment one is: single flute profile is propped up pad 7 fixing positions and is, groove is buckled in winding up of each bow member downwards, the fixing pad that makes progress of notch between two bow members, and film-pressing line is pressed in the groove.

Embodiment three: honeycombed is propped up the double-deck canopy film booth of pad

And embodiment one do not exist together for: whole pad can be clipped between nexine and the outer field canopy film.
