Air column enclosure device for suspension and tensioning installation and manufacturing method

Abstract

The invention provides an air column enclosure device for suspension and tensioning installation and a manufacturing method, and belongs to the technical field of an inflatable double-layer lighting surface of a tensioning structural plastic film green house. The air column enclosure device comprises a plurality of air column structures which are arranged in parallel and integrally connected, a diaphragm structure which is integrally connected with two ends of the air column structures and a pull rope which is integrally connected with a film material forming the air column structures; when two ends of the pull rope are strained, the air column structures are unfolded; the pull rope is subjected to the positive and negative pressure from the lighting surface of the air column structures. Two methods are adopted for manufacturing the device. When the device is used, even when an individual air column cavity is broken and the air leaks, the heat preservation performance and lighting performance of the air column enclosure structure are not affected, the large-area and high-degree loosening collapse of the lighting surface can be avoided, and the normal application of the green house is not affected; the device is installed in a suspending and tensioning manner, so that convenience in installation and construction is realized, no beam column supporting structure is needed, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of an inflatable double-layer plastic film lighting surface of a plastic film greenhouse with a tension structure, in particular to an air column enclosure device and a manufacturing method for hanging tension installation. Background technique [0002] When only one layer of plastic film is used for the enclosure structure of the lighting surface of the traditional plastic film greenhouse, the thermal insulation is very poor in low temperature seasons, which affects normal use. [0003] In order to improve the thermal insulation of the lighting surface enclosure structure of the plastic film greenhouse, a double-layer plastic film enclosure structure is used for the improved plastic film greenhouse lighting surface. [0004] The patent application with the application number 99808713.0 discloses an inflatable covering element and an assembly (rain shelter) obtained by putting the element together on the sup...

AI Technical Summary

Problems solved by technology

The characteristic of this structure is that the manufacturing process is simple, but in use, once the cavity is damaged and leaks air, it will cause a large area and a large degree of collapse of the plastic film lighting surface of the greenhouse, and will cause a large piece of plastic film to relax. This kind of air-filled plastic film cavity that relies on multiple support beams to support the tension will accumulate rain and snow in local gentle areas, and there is a risk of local collapse under pressure, thus affecting the normal use of rain shelters or greenhouses

Second, the inflatable plastic film rain shelter or the lighting surface of the greenhouse are all installed with a "beam-column support structure", which requires a dense "beam-column support structure", and the construction cost is very high

Third, there are too many contact surfaces between the dense "beam and column support structure" and the inflatable cavity, which will cause too much wear and tear on the inflatable cavity, and there are hidden dangers in the safety of the rain shelter or greenhouse

Fourth, the patent application with the application number 99808713.0 discloses an inflatable cover element. If it is used to build a greenhouse with a tension structure, it is difficult to carry out closed butt joint operations between adjacent elements. During the operation process and the application process after docking, there is a transverse pulling force on the cavity, so that the inflatable cavity of the component is at risk of being torn and leaking air; at the same time, there is only one diameter of about 1 meter between the two pull ropes Under the action of wind, rain and snow, the cavity is in the dynamic movement of ups and downs, and the structure of the cavity is prone to damage and air leakage

[0007] In the field of packaging technology, although the diameter of the individual air column cavity of the plastic film air column roll used is small, it is relatively safe to use, and there is no need to worry about individual air column damage and air leakage, but it requires a beam-column structure during installation, and also The two ends of the air column structure cannot be safely fixed (when there is no diaphragm structure, directly fixing the two ends of the air column with fasteners is likely to cause air column damage and air leakage); moreover, the length of the air column is very small (less than 3 meters) , less than the slope length of the greenhouse lighting surface (slope length greater than 3 meters), not suitable for the lighting surface structure of the greenhouse
