Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to the disclosure of a heat insulating structure for an open window portion where the heat insulating effect is particularly reduced in the heat insulating construction of a structure.

(Prior Art) Conventionally, this type of open window is usually shielded from the outside world by a glass plate, but since the glass plate has high thermal conductivity, a curtain is used to increase the heat insulation effect. It is planned that the opening windows will be shielded with glass panels, etc., or the glass plates will be placed opposite each other at appropriate intervals to create a so-called double sash, which will also provide light and heat insulation.

(Problems to be solved by the invention) When shielding an opening window with a curtain, etc.
Although it can block the radiation of heat toward the open window, if there is a gap between the curtain and the open window through which indoor air flows, the air that comes into contact with the glass plate is affected by the outside temperature. Since convection occurs between the indoor air and the indoor air, complete insulation cannot be achieved, and the problem is that light is blocked because it blocks light.

In addition, when the glass plates are double-layered and a sealed air layer interposed between the glass plates is used as a heat insulating material, it is necessary to provide a sufficient air layer. It is necessary to make the gap large, requiring a relatively large installation space for the glass plate, and condensation occurs in the sealed air space, making it difficult to treat wastewater in the sealed space. That's what I was doing.

(Means for Solving the Problems) The heat insulating window according to the present invention was devised to solve the various problems in such conventional precedents, and the insulating window according to the present invention is A liquid with good heat insulation and lighting properties, that is, large heat storage capacity and translucency, is sealed between the plates to provide complete insulation that does not affect sufficient lighting in the openings, allowing heating and cooling in buildings. The aim is to improve efficiency.

In particular, in the heat insulating window according to the present invention, it is possible to simultaneously perform the function of daylighting through the open window, the intake of solar heat through the incidence of direct rays, and the ability to view the scenery etc., at the same time as the heat insulating function of the open window. In order to reduce the installation space of the heat insulating window, its structure is such that transparent or semi-transparent plates such as reinforced glass or plastic plate glass are stretched facing each other at a predetermined interval, and a sealed space is formed between the stretched plates. It has a structure in which a transparent or translucent flame retardant liquid with a high boiling point, low freezing point, and no photocurability is sealed inside.

(Function) In the present invention configured as described above, the encapsulant is a liquid and has extremely high fluidity, so it can evenly and uniformly adhere to the transparent or translucent plates that are stretched facing each other. Since the liquid serving as the encapsulant has a high boiling point and low coagulation properties, its volume does not significantly increase or decrease even at high temperatures or low temperatures caused by direct sunlight irradiation. Furthermore, since the liquid is a flame retardant liquid that does not have photocuring properties, it will not change in quality even after long-term ultraviolet irradiation.
There is no ignition of the liquid or ignition from the liquid when high temperatures occur such as in the event of a fire.

(Example) A typical example of the heat insulating window structure according to the present invention will be described below with reference to the attached drawings. 1, 1 is a transparent or semi-transparent plate material such as reinforced plate glass or reinforced plastic plate glass, These plates 1, 1 are arranged side by side with a window frame material etc., and the circumferential surface thereof is sealed to form a gap for sealing the liquid 2,
It is planned that a liquid 2 having the following characteristics will be filled and sealed in this gap.

In other words, the sealed liquid 2 should be transparent or translucent so as not to impair the lighting function as much as possible, and should have a freezing point that is as low as possible, for example around -50°C, so that it does not particularly interfere with the viewing of landscapes, etc. In addition to these properties, it is expected to be made of a material that has a relatively high boiling point of around 300°C. Alternatively, it is planned to use a material that does not become cloudy and is flame retardant.

In order to meet the requirements for such characteristics, the present invention plans to use a liquid silicon polymer such as silicone oil as the liquid 2, and dimethyl-based or methylphenyl-based material may be used depending on the purpose of use. By mixing trimethylchlorosilane, lithium stearate, etc. with silicon oil, etc., and changing the mixing ratio, appropriate translucency and fluidity can be obtained.

In addition, when enclosing the liquid 2 in the above description, an internal gap corresponding to the expansion and contraction capacity of the enclosed liquid 2 itself is separately provided between the plates 1, 1.
This effectively avoids the inconvenience caused by making the space between the two spaces as narrow as possible.

(Effects of the invention) The presence of the sealed liquid 2 hardly transmits the indoor temperature even when the outside temperature shifts to negative, and heating loss in severe cold can be reduced by leaving curtains etc. open. In other words, this structure effectively prevents the occurrence of condensation on the interior side of the room, and prevents wear and tear on the interior decoration and damage to the flooring due to the outflow of condensed water. This effectively prevents such problems.

In addition, since the liquid 2 has a high boiling point and a low freezing point, the liquid 2 itself does not freeze and expand in severe cold as described above, and on the contrary, when exposed to direct sunlight for a long period of time, the liquid 2 itself does not freeze and expand. Since the liquid 2 will not be inadvertently vaporized even if the temperature rises, it is possible to effectively prevent an increase in the internal pressure in the gap in which the liquid 2 is enclosed, which is made up of a plate. This effectively prevented deformation and breakage accidents.

Therefore, by increasing the thermal stability of the liquid 2 and reducing its coefficient of expansion, it is possible to narrow the gap between the plates stretched facing each other, thereby increasing the internal voids that allow the expansion of the liquid 2 in the constituent voids. This makes it possible to reduce the initial effect even in such cases.

Furthermore, since the liquid 2 is non-photocurable and flame-retardant, it can be prevented from deteriorating even when exposed to ultraviolet rays for a long period of time, and the transmittance can be reduced due to hardening or clouding of the liquid 2. This prevents the liquid 2 from igniting even in the event of high temperatures such as a fire, and effectively prevents the spread of fire from the opening window.

It should be noted that the plates 1 and 1 mentioned above are not only fixed to the opening of the structure and have a so-called fit-in structure, but also because the enclosing material is liquid and does not harden or deteriorate. Since no minute cracks, bubbles, etc. occur even with 1.1 vibration, it can also be used as a window member that can be slid or rotated to open and close.

Furthermore, in order to improve the heat insulation properties of such window openings, it is separately required that the material of the so-called window frame to which the plates 1, 1 are fixed be selected from among materials with as low thermal conductivity as possible. In either case, the thickness of the window itself could be made as thin as possible, and problems with installation space and external appearance could be corrected.
