Detailed Description
The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.
The inflatable membrane structure of the invention comprises an air bearing type, an air rib type, an air pillow type and an air bag type, and the inflatable membrane structures are all applicable to the invention.
The heat-insulating structure is a functional coating, and the type and the thickness of a heat-insulating material can be selected through thermal calculation according to the requirements of heat insulation and heat insulation, so that the thermal performance of a membrane body is improved, the higher standard is met, and the application requirement and the function upgrade in the inflatable membrane are realized. The invention is provided with a multilayer heat insulation structure, so that the heat insulation material can be selected according to functions in a diversified and targeted manner, such as heat insulation, heat preservation, moisture absorption resistance and the like.
As shown in fig. 1, the inflatable membrane structure in the prior art includes an outer membrane 1 and an inner membrane 2, the outer membrane 1 and the inner membrane 2 are connected by outer welding seams 11 arranged at intervals in multiple sections, and the heat insulation structure between the outer membrane 1 and the inner membrane 2 is composed of outer heat insulation layers 12 respectively arranged between two adjacent outer welding seams 11 in multiple sections. The common inflatable membrane structure is in a converging connection with a point (namely a line extending along a rib) on an outer membrane and an inner membrane at an outer welding seam 11, the outer membrane and the inner membrane are not spaced enough due to the connection mode, a heat insulation structure cannot be installed and welded at one point, even an air interlayer between the outer membrane and the inner membrane cannot be formed, the heat insulation structure is also one-section and discontinuous, a cold bridge phenomenon exists, and the heat insulation effect is poor.
Example 1
Based on the prior art, one of the improved structures is as follows: a corresponding increase in the connecting film strip 4 at each outer weld 11 provides sufficient spacing between the outer film 1 and the inner film 2. In the inflatable membrane structure, the point that the outer membrane 1 and the inner membrane 2 are welded together is eliminated, the outer membrane 1 is separated from the inner membrane 2, the distance between the outer membrane 1 and the inner membrane 2 is enlarged, the air interlayer between the outer membrane 1 and the inner membrane 2 is thickened, a heat insulation structure can be installed, and the heat insulation performance of a part without heat insulation filling is also improved. However, because of the installation problem, the heat insulation structure still comprises a plurality of sections of outer heat insulation layers 12 respectively arranged between two adjacent outer welding seams 11, the heat insulation structure still cannot be continuous and has no broken seam, the cold bridge phenomenon still exists, and the heat insulation effect is not good.
As shown in fig. 2, aiming at the problems of unreasonable structure of the inflatable membrane and poor heat insulation effect, the invention firstly adds a layer of lining membrane 3, the outer layer membrane 1, the inner layer membrane 2 and the lining membrane 3 are stacked, and a heat insulation structure is arranged between two adjacent membranes to form an integral structure of three-layer membrane and two-layer heat insulation. If the added lining film 3 and the heat preservation structure are consistent with the original structure and are directly stacked up and down, the heat preservation structure still cannot be continuous, a broken seam exists, and a cold bridge still exists, so that the heat preservation structures need to be overlapped in the stacking direction of the films, the cold bridge is avoided by utilizing the overlapped part, and the heat preservation and insulation effect is improved.
It should be noted that the membrane structure, the heat preservation system and the inflatable membrane building have better heat preservation or heat insulation capability, and the heat transfer coefficient of the traditional inflatable membrane heat preservation process is about 0.35-0.55W/(m)2K), meanwhile, the heat-insulating film can improve the heat-insulating capacity by 50-100%, and is suitable for inflatable film buildings with large temperature difference between indoor use environments and outdoor use environments, such as skiing, skating halls, swimming halls, water orchards and the like. And the film structure can be applied to other scenes such as a mixed film structure and the like, and is not limited to the application range listed above.
In the thermal insulation construction method of the inflatable membrane structure according to embodiment 1, the thermal insulation structure is installed after the two adjacent membranes are inflated, or the membranes inside the thermal insulation structure are laid on the ground after being laid on the ground, and then inflated again for forming.
Example 2
As shown in fig. 3, on the basis of embodiment 1, a layer of lining film 3 and a corresponding heat preservation structure are further added to form a three-layer film and two-layer heat preservation overall structure, so that the structure is reasonably arranged, and the heat preservation effect is good.
The method comprises the following steps: the outer layer film 1, the inner layer film 2 and the inner lining film 3 are sequentially stacked from outside to inside; outer membrane 1 with inner membrane 2 is connected through the outer welding seam 11 that the multistage interval set up, outer membrane 1 with insulation construction between the inner membrane 2 sets up outer heat preservation 12 between two adjacent outer welding seams 11 respectively by the multistage, inner membrane 2 with interior welding seam 21 that inner lining membrane 3 set up through the multistage interval connects, inner membrane 2 with insulation construction between interior welding seam 3 sets up the interior heat preservation 22 between two adjacent inner welding seams 21 respectively by the multistage, outer welding seam 11 with interior welding seam 21 sets up at the range upon range of orientation staggered joint of each membrane, outer heat preservation 12 with interior heat preservation 22 sets up in the range upon range of orientation of each membrane crisscross to overlap each other in the range upon range of orientation of each membrane and set up.
Certainly, if a non-staggered joint mode is adopted, a layer of inner lining film 3 with the same structure and an inner heat-insulating layer 22 aligned with the outer heat-insulating layer 12 are directly added on the inner side of the inner layer film 2, and a three-layer film and two-layer heat-insulating integral structure is also formed, so that the temperature of an indoor use environment can be better ensured, and the operation cost can be saved.
Aiming at the inflatable membrane structure of the embodiment 2, the heat preservation construction method comprises the following steps:
step 1: the inner side of the outer layer film 1 is provided with the inner layer film 2 through a plurality of sections of outer welding seams 11 which are arranged at intervals, after the film body is formed by inflation, a plurality of sections of outer heat preservation layers 12 which are respectively arranged between two adjacent outer welding seams 11 are arranged between the outer layer film 1 and the inner layer film 2;
step 2: the inner side of the inner layer film 2 is provided with the inner lining film 3 through a plurality of sections of inner welding seams 21 which are arranged at intervals, after the film body is formed by inflation, a plurality of sections of inner heat preservation layers 22 which are respectively arranged between two adjacent inner welding seams 21 are arranged between the inner layer film 2 and the inner lining film 3.
On the basis of the technical scheme of the embodiment, the following additional improvements can be made: at least one additional film is further stacked on the inner side of the lining film 3, and heat insulation structures are also arranged between the lining film 3 and the additional film and between adjacent additional films. The structure of the additional film is similar to that of the lining film 3, the heat-insulating layers of the adjacent heat-insulating structures can be designed into staggered joints, and the heat-insulating effect can be better improved by the multilayer films and the heat-insulating structures. In addition, connecting film belts 4 which enable the inner lining film 3 and the additional films to have enough space and be arranged between the adjacent additional films can be arranged between the inner lining film and the additional films, so that the air isolation layer has enough thickness and the installation of the heat insulation structure is ensured. The multilayer structure is compounded by adopting the process of adding the connecting membrane strip 4, thereby further eliminating cold bridges and improving the heat preservation and insulation capability.
Based on the above, the heat preservation construction method further comprises a step 3 which is carried out after the step 2: at least one layer of additional film is arranged on the inner side of the lining film 3, after the film body is formed by inflating, heat insulation structures are arranged between the lining film 3 and the additional film and between the adjacent additional films. Specifically, a layer of additional film is arranged on the inner side of an inner lining film 3 through a welding line, after a film body is formed through inflation, a heat insulation layer is arranged between the inner lining film 3 and the additional film, then a layer of additional film is continuously arranged on the inner side of the additional film through the welding line, after the film body is formed through inflation, the heat insulation layer is arranged between the inner lining film 3 and the additional film, and the like are carried out until at least one layer of additional film and the corresponding heat insulation structure are completely arranged.
In addition, the following modifications are also possible in example 1: by providing the connecting film strips 4 with a slant, an overlap at the weld seam, which may be understood as a staggered arrangement, it may be possible to avoid cold bridges. However, when the external insulation layer 12 is installed in the inflatable membrane structure, the dead weight of the external insulation layer 12 can cause a large gap at the staggered floor, the shielding effect is not ideal, and the shielding effect of the staggered seam arrangement of embodiment 2 can be more complete. In addition, the improvement scheme of the embodiment 1 is only that three layers of films are arranged on the local part, and the embodiment 2 is that any part of the whole film body is provided with the three layers of films, so that a multi-layer heat insulation layer and an air isolation layer can be formed, and the heat insulation effect is better.
In embodiment 2, the connecting film strip 4 may be vertically or obliquely arranged between two adjacent films.
