In order to solve the problem that there is the cold bridge in the air film structure among the prior art, the utility model provides a heat preservation air film structure of no cold bridge.
As shown in fig. 1 and 2, the cold bridge-free heat preservation gas film structure comprises an outer layer film 10, an intermediate layer film 20, a heat preservation layer film 30 and an inner layer film 40, wherein the intermediate layer film 20 is located between the outer layer film 10 and the ground, the intermediate layer film 20 is provided with a plurality of first welding positions 21, the plurality of first welding positions 21 are arranged at intervals, the intermediate layer film 20 is welded on the outer layer film 10 at the first welding positions 21, heat preservation spaces are formed between two adjacent first welding positions 21 by the intermediate layer film 20 and the outer layer film 10, the heat preservation spaces are multiple, and cold bridges are formed at the first welding positions 21 by the intermediate layer film 20 and the outer layer film 10; a plurality of heat preservation layer films 30 are arranged, and the heat preservation space is internally provided with the heat preservation layer film 30; the inner film 40 is located between the middle film 20 and the ground, the inner film 40 is spaced apart from the first welding site 21 to form a thermal insulation gap therebetween, and at least a portion of the inner film 40 is connected to the middle film 20.
Through set up heat preservation tunic 30 on the heat preservation tunic structure of no cold bridge, can completely cut off the outside cold air of the heat preservation tunic structure of no cold bridge, reduced the heat exchange of air film space with the outside to reduce losing of heat in the air film space, the air film space of being convenient for maintains at comfortable temperature, has reduced the heat exchange simultaneously and can also reduce electric power system's use, the energy saving. Because the intermediate layer film 20 and the outer layer film 10 are welded together at the first welding position 21, a heat preservation space for accommodating the heat preservation layer film 30 can be formed between the intermediate layer film 20 and the outer layer film 10. Because in first welding position 21 department, outer membrane 10 and intermediate layer membrane 20 direct contact, in first welding position 21 department, the gas film space is great with outside heat exchange, and then make the gas film space temperature lose very fast, inner membrane 40 is located between intermediate layer membrane 20 and the ground, and with first welding position 21 interval setting, make and form the heat-insulating clearance between inner membrane 40 and the first welding position 21, make the outside cold air of the heat preservation gas film structure of no cold bridge can directly carry out the heat exchange with the hot-air in gas film space, greatly increased the heat preservation performance of the heat preservation gas film structure of no cold bridge.
As shown in fig. 1 and 2, both ends of each insulation film 30 are connected to two adjacent first welding sites 21. The arrangement can increase the heat-insulating layer film 30 to isolate the heat exchange between the intermediate layer film 20 and the outer layer film 10 as much as possible, greatly increase the heat-insulating property of the heat-insulating gas film structure without cold bridges, and ensure that the heat-insulating gas film structure without cold bridges is more energy-saving and environment-friendly.
Example one

This arrangement facilitates welding of the second welding sites 41 to the interlayer film 20 with equal distances between the respective second welding sites 41. Or, the second welding positions 41 are welded at the middle positions between the two adjacent first welding positions 21, so that a cold bridge is arranged between the two adjacent second welding positions 41, the heat exchange of the heat-insulating air film structure without the cold bridge at the cold bridge is reduced, and the heat-insulating performance of the heat-insulating air film structure without the cold bridge is greatly improved.
Specifically, the reflectance of the inner film 40 is equal to or higher than the reflectance of the intermediate film 20. The middle layer film 20 and the inner layer film 40 are both high-reflectivity materials, which can reduce the heat loss to 60% of the original film, so that the heat in the cold-bridge-free heat-insulating air film structure cannot be easily conducted through the film materials. Even if part of heat is conducted through the reflecting film material, the heat loss of the heat insulation layer film 30 can be greatly reduced, and therefore the overall heat insulation performance of the air film is improved. The reflectivity of the inner layer film 40 is larger than that of the middle layer film 20, so that the temperature transmitted to the middle layer film 20 can be reduced, the heat exchange of the air film space can be further reduced, and the heat insulation performance of the air film structure is greatly improved.

The inner layer film 40 is arranged in such a way that the inner layer film cannot be welded to the first welding position 21, so that a heat insulation gap is formed between the inner layer film 40 and the first welding position 21, and the heat insulation performance of the heat insulation gas film structure without a cold bridge is ensured.
The heat preservation performance of the air film structure in the embodiment is improved by 5% compared with that of other conventional air film structures, and the waste of energy is greatly reduced.
It should be noted that the material of the intermediate layer film 20 and the inner layer film 40 may be a PVC-based film.

In this embodiment, the inner film 40 is one, the inner film 40 has a plurality of second welding positions 41, the plurality of second welding positions 41 are arranged at intervals, the intermediate film 20 further has a plurality of connecting structures, each of the first welding positions 21 extends downward to form at least one connecting structure, and the second welding positions 41 are connected to the lower ends of the connecting structures. Through set up connection structure on middle tunic 20, and then make second welding position 41 weld on connection structure, make first welding position 21 misplace in vertical direction with second welding position 41, and then make first welding position 21 can not be with second welding position 41 direct contact, make inner tunic 40 and first welding position 21 can not direct contact, form thermal-insulated clearance between inner tunic 40 and the first welding position 21 in order to guarantee, in order to reduce the heat exchange of the heat preservation gas film structure that does not have the cold bridge, guarantee the temperature in the gas film space.

This arrangement facilitates fabrication and welding of the interlayer film 20 and the inner film 40.
Of course, the number of the first welding locations 21, the second welding locations 41 and the connecting structures are different, but it is only necessary to ensure that the second welding locations 41 can be welded to the connecting structures.
Specifically, the length of the connecting structure is greater than or equal to 5 cm and less than or equal to 10 cm. The heat preservation performance of the heat preservation air film structure without the cold bridge is guaranteed, and meanwhile the cost and the weight of the heat preservation air film structure without the cold bridge are reduced as far as possible.
