Problems solved by technology

This method must first ensure the quality of the shed film, and it must not leak air under high pressure for a long time. Secondly, the construction is complicated. Finally, the lighting performance is reduced, which is not conducive to popularization.

Embodiment 1

[0025] Example 1: Double-layer film greenhouse with double-groove support pads

[0026] The laying method of the double-layer shed film greenhouse is:

[0027] 1. See figure 1 , 5 6. Build a greenhouse frame. If it is a solar greenhouse, the frame includes three walls 2 and the arch 1 on the wall; if it is a simple greenhouse, the frame is the arch 1;

[0028] 2. Lay the inner shed film 3 on the upper chord 1.1 of the arch frame and fix it initially;

[0029] 3. The fixed cross-section on the inner shed film 3 is a double-groove profile support pad 4, and its cross-section can be dumbbell-shaped (see image 3 ), can also be X-shaped (see Figure 4 ). Two back-to-back upper grooves and lower grooves are formed on the support pad. The lower groove of this supporting pad is buckled on the upper chord 1.1 of arch 1.

[0030] 4. Lay the outer shed film 6 on the support pad and fix it initially;

[0031] 5. Tighten the laminating line 5 and press it in the upper groove of t...

Embodiment 2

[0032] Example 2: Double-layer film greenhouse with single-groove support pad

[0033] see figure 2 , 6 , and the difference from Embodiment 1 is: the fixed position of the single-groove support pad 7 is that the groove is buckled downward on the upper chord of each arch, and the support pad with the notch upward is fixed between the two arch frames, and the laminating line Press into the groove.

Embodiment 3

[0034] Example 3: Double-layer shed film greenhouse with honeycomb support pad

[0035] The difference from the first embodiment is that the entire supporting pad can be sandwiched between the inner layer and the outer layer of the shed film.

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

technical field [0001] The invention relates to a laying method of plastic film greenhouses for agriculture, in particular to a laying method of double-layer film greenhouses. Background technique [0002] Greenhouses have shown great advantages since their birth. More and more areas adopt greenhouses, and more and more farmers rely on greenhouses to embark on the road to prosperity. Present greenhouse is mainly made of shed frame and laying shed mold on the frame. The shed film is not only a light-collecting surface, but also a heat-dissipating surface. The heat dissipated through the greenhouse film accounts for 73-80% of the total heat dissipation of the greenhouse. Due to the loss of a large amount of heat, there will be fogging, condensation, frosting and even freezing in the shed in severe winter. This phenomenon is very unfavorable to planting, breeding or as a place for production activities. For this reason, for a long time, people have thought of many ways to s...
