Description

The present invention relates to a system and method for maintaining the insulation, soundproofing and security of a container.

With the spread of air conditioning and heating equipment, it has become possible to maintain a comfortable temperature in living spaces by keeping the temperature constant regardless of the outside temperature. However, in recent years, the outside temperature has been rising due to global warming, so more energy is required to maintain this temperature. Also, in countries close to the poles and countries close to the equator, a large amount of energy is required to maintain a comfortable temperature in living spaces. When the temperature of the living space is low, it is possible to deal with this by changing clothing or using renewable energy (such as firewood), but when the temperature of the living space is high, electricity, which generates greenhouse gases, is used. In Japan, the average outside temperature during the daytime when air conditioning is on in the summer, exceeds 30°C for several months, but in countries near the equator, it remains almost the same throughout the year.
According to a report by the Japan Building Materials & Housing Equipment Industry Association, the proportion of heat output from living spaces during heating in winter is 5% from the roof, 7% from floors, 15% from exterior walls, 15% from ventilation, and 58% from openings such as windows. On the other hand, the proportion of heat input into living spaces during cooling in summer (daytime) is 11% from the roof, 3% from floors, 7% from exterior walls, 6% from ventilation, and 73% from openings such as windows. Since the proportion from openings such as windows is extremely high, by insulating openings such as windows, it is possible to create a comfortable space while reducing the energy consumption required to maintain the indoor temperature.
Double-glazed windows are a common device and method for reducing the transfer of heat through windows; however, they are very heavy, and when an aluminum alloy with high thermal conductivity is used for the window frame to ensure strength, heat enters and leaves through the frame, causing condensation. Therefore, the following technologies have been proposed to improve insulation performance and create a comfortable space.
For example, Patent Document 1 describes a technology that "provides a daylight/insulation window that is relatively inexpensive, can be constructed thin, and can steadily take in natural light regardless of whether the weather is sunny or cloudy, creating a bright natural environment while also having excellent thermal insulation properties, by arranging a daylight lens such as a linear Fresnel lens between two transparent plates, and forming an air layer between at least one of these plates and the daylight lens."
Patent document 2 describes a technology that "provides a light-gathering insulation material having a number of synthetic resin films and a number of spacers arranged between the films, separating the window glass from the interior side by an air layer, and also provides a caulking material that seals the gap between the light-gathering insulation material and the window glass."
Patent document 3 describes a technology for providing, "an inexpensive insulated shoji structure and an insulated double window structure that are composed of two sliding shoji panels and a wooden frame that holds the shoji panels, which are lightweight and airtight and can turn existing windows into insulated windows."
Patent document 4 describes a technique for producing vacuum insulated glass in which the window panes are assembled in a single step by providing glass panes, metal spacers, corner and frame metal sealing elements which are brazed onto an adhesive layer previously deposited on the edge area regions of the glass panes.
On the other hand, abnormal weather phenomena caused by global warming, such as the increase in the power of typhoons and the occurrence of tornadoes, are increasing the opportunities for window damage caused by flying objects. Even under normal circumstances, the incidence of "glass breaking" among residential burglary remains high, but the technology of sealing air or argon (thermal conductivity of approximately 0.02 W/mK), which has excellent thermal conductivity properties, between multiple panes of glass, the technology of making window frames out of resin, and the technologies shown in Patent Documents 1 to 4 are not able to deal with this.
Furthermore, with the recent concentration of population in urban areas and the development of transportation networks, there is a demand for measures to be taken against noise intrusion from adjacent rooms, floors above or below, and windows in apartment buildings, as well as noise and vibrations generated by the passage of roads, railways, and airplanes; however, the techniques shown in Patent Documents 1 to 4 do not address these needs.

Japanese Patent Application Laid-Open No. 11-81813 JP 2012-188818 A JP 2015-1110 A JP 2017-535696 A

Windows are the most vulnerable parts of buildings in terms of the transfer of heat and sound, and against flying objects and intruders. The functions of windows can be broadly divided into letting in light from the outside and allowing the view of the outside to be seen. Glass is a common material that fulfills both of these functions, and its thermal conductivity is about 1 W/mK, which is lower than that of metals (about 30 W/mK to 300 W/mK (aluminum is about 200 W/mK)) but higher than that of resin (about 0.3 W/mK) and air (about 0.03 W/mK). For this reason, technologies that enclose air or argon (thermal conductivity about 0.02 W/mK), which have excellent thermal conductivity properties, between multiple pieces of glass, technologies that make window frames out of resin, and technologies shown in Patent Documents 1 to 3 are used.
On the other hand, as described in Reference 4, it is possible to improve the thermal insulation performance of a window made of multiple panes by evacuating the space formed between the panes. However, when the pressure in the space formed between the panes (the inner surface of the panes) decreases, a spacer is inserted to prevent the panes from being broken by the atmospheric pressure acting on the outer surface of the panes, and the spacer is also in the field of view when viewing the outside scenery, which is an important element of the window function. In addition, in order to form a vacuum space, it is necessary to seal the periphery of multiple panes, but if a sealing technique based on welding glass with low deformability is used, the difference in expansion caused by the temperature difference between the inner pane and the outer pane cannot be absorbed, and the panes may be broken.

The basis of soundproofing is to "block sound energy." Since sound is transmitted by vibrating air, solids, liquids, etc., effective and efficient soundproofing can be achieved by installing equipment to prevent sound from leaking out to the outside and to prevent sound from entering from the outside.
Generally, the vibration energy of sound is more easily transmitted the harder and flatter the floor or wall surface is, whereas sound is less likely to be transmitted through porous or uneven materials because the energy is attenuated when sound enters the material due to vibrations. Taking advantage of this property, the following soundproofing materials have been developed:
(1) Sound-absorbing material: This material is made up of materials that attenuate sound by converting the vibrations of sound waves transmitted through the air into thermal energy. It is effective in reducing unpleasant echoes in a room and adjusting reverberation time. Examples of this material include glass wool and urethane sponge.
(2) Soundproofing material: This refers to a material that blocks sound waves propagating through the air, by not allowing sound to pass through but instead bouncing it back to the outside. Examples of this include soundproofing mats and soundproofing sheets.

The present invention aims to provide a heat insulation, soundproofing and security system for a container including a window that has a structure and function to prevent the window from being damaged by external noise or strong winds, and a method for maintaining the heat insulation, soundproofing and security of the container, by creating a vacuum in the space formed between materials that function as windows and allow multiple layers of light to pass through and/or allow the view of the outside, while maintaining as much of the window's function as possible of "gathering light from outside and/or allowing the view of the outside."

The invention described in claim 1 is characterized in that the container has a double structure with a vacuum inside, part or all of which is made of a vacuum material, to prevent the transfer of heat and sound between the outside and inside of the container, and is equipped with a device for continuously reducing the pressure inside the double structure in order to maintain the vacuum state inside the double structure.

The reason why the present invention is provided with a device for continuously reducing the pressure inside the double structure is that most materials, except for metals and ceramics, are permeable to gas, so if a double structure with a vacuum inside is created using a material such as a resin with excellent insulating properties, measures to reduce the internal pressure periodically or continuously are required. Conversely, by providing the system with a device for continuously reducing the pressure inside the double structure, it becomes possible to use materials with excellent insulating, soundproofing, and safety properties as the material that makes up the container.

The invention described in claim 2 is characterized in that in a container, in order to prevent the transfer of heat and sound between the outside and inside of the container, part or all of the container is made into a double structure with an internal vacuum, and in order to maintain the vacuum state inside the double structure, a method is used in which the pressure inside the double structure is continuously reduced.

The invention described in claim 3 is characterized in that in a container, in order to give the material that constitutes the container the function of letting in light from the outside and/or allowing the outside scenery to be seen, a translucent material that is highly impact resistant and difficult to cut is placed in part or all of one or both of the materials that constitute the double structure, making it possible to give the container the function of a window that combines thermal insulation, soundproofing and security functions.

The invention described in claim 4 is characterized in that in a container, in order to give the material that constitutes the container the function of letting in light from the outside and/or allowing the outside scenery to be seen, a method is used in which a translucent material that is highly impact resistant and difficult to cut is placed on part or all of one or both of the materials that constitute the double structure, making it possible to give the container the functionality of a window that combines thermal insulation, soundproofing and security functions.

The invention described in claim 5 provides a material that is installed around a material that functions as a multi-layered light-transmitting window and/or allows the view of the outside to be seen, and that forms an enclosed space, by providing a row of grooves with a width close to the thickness of the flat plate, and inserting the periphery of the multi-layered light-transmitting flat plate and/or allows the view of the outside into the grooves, thereby tightly adhering and fixing the multi-layered light-transmitting flat plate and/or allows the view of the outside to be seen, and thereby providing a multi-layered light-transmitting flat plate and/or allows the view of the outside to be seen, and a material that is installed around the material that forms an enclosed space, by providing a row of grooves with a width close to the thickness of the flat plate, and inserting the periphery of the multi-layered light-transmitting flat plate and/or allows the view of the outside to be seen, and thereby providing a multi-layered light-transmitting flat plate and/or allows the view of the outside to be seen, and This double-layered structure has a material inserted between the flat plates that can be used to transmit light and that can show the outside scenery to create a vacuum in the sealed space formed by the flat plates and the material placed around them, and acts as a support (spacer) to prevent the sealed space, which is a vacuum inside, from being deformed by atmospheric pressure. A sealant is filled and applied to the area where the double-layered structure and the material placed around the double-layered structure that forms the sealed space come into contact to increase airtightness, and the internal pressure is continuously reduced to maintain the vacuum state, making it possible to maintain the vacuum insulation function of the window.

The invention described in claim 6 provides a material that is installed around a material that functions as a multi-layered light-transmitting window and/or allows the view of the outside, and that forms an enclosed space, with a single row of grooves or two rows of grooves with a width close to the thickness of the flat plate, and by inserting the periphery of the multi-layered light-transmitting flat plate and/or allows the view of the outside into this groove, the multi-layered light-transmitting flat plate and/or allows the view of the outside are tightly attached and fixed to the material that is installed around it and forms an enclosed space, thereby enabling the view of the multi-layered light-transmitting flat plate and/or allows the view of the outside to be seen. This double-layered structure has a material that acts as a support (spacer) inserted between the multi-layered light-transmitting and/or transparent flat plates that allow the outside scenery to be seen in order to create a vacuum in the sealed space formed by the flat plates and the material placed around them, and to prevent the sealed space with a vacuum inside from deforming due to atmospheric pressure. The double-layered structure and the material placed around the double-layered structure that forms the sealed space contact each other with a sealant to increase airtightness, and the method of continuously reducing the internal pressure to maintain the vacuum state allows the vacuum insulation function of the window to be maintained.

The invention described in claim 7 is characterized in that in a double-layered structure made of a material with the function of a light-transmitting window and/or a window through which the outside scenery can be seen, which is installed for the purpose of letting in light from the outside and/or viewing the outside scenery, a material that is lightweight and has a shape and material with excellent insulating properties is inserted to act as a support (spacer) in order to prevent the vacuum-sealed space inside the double-layered structure from being deformed by external pressure.

The invention described in claim 8 is a double-layered structure made of a material with the function of a window that allows light to pass through and/or allows the view outside to be seen, and is installed for the purpose of letting in light from the outside and/or allowing the view outside to be seen.

By using this invention, it is possible to maintain the thermal insulation, soundproofing and security functions of buildings.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
Fig. 1 shows a container with a double-layered structure with a sealed vacuum space inside. When the inside of the container is evacuated, it is necessary to insert a material equivalent to a support (spacer) to prevent the material that constitutes the container from being deformed by external pressure. If this is inserted into a window that requires light transmission and/or the ability to see the outside scenery, the original function will be reduced. By using this invention to form a support (spacer) that supports the vacuum space using a material in the shape of a design, letter, number, picture, etc., it becomes possible to obtain effects other than those required for conventional windows.

The present invention can be applied to maintaining the insulation, soundproofing and security of containers.
