Description

  The present invention relates to a method of making a single layer glass sash window into a heat insulating window.

  In recent years, as a sash window used in a house, a heat insulating sash window made of a pair of glasses is often used in consideration of cooling efficiency and heating efficiency. Moreover, the conventional single layer glass sash window which is not a heat insulation sash window is also replaced with a heat insulation pair glass window at the time of renovation, and a heat-efficient living environment is implement | achieved.

However, the conventional technique has the following problems.
Since the density of the glass is 2.5 g / cm ³ , the glass is heavy, and there is a problem that handling of the frame receiver such as the design strength of the frame receiver is not always perfect when two sheets are used. In order to compensate for this, the glass thickness is slightly reduced, for example, 5 mm for single-layer glass, but a glass pair structure of 3 mm glass + 6 mm air layer + 3 mm glass is often used for heat insulation of the window glass. However, this time there was a problem that the glass strength was weakened.

  In addition, the rail or pier that receives the glass sash window may not be replaced due to the relationship with the wall, and there is a problem that the thickness of the sash window frame itself cannot be changed. In other words, there is a problem that it is difficult to make an existing single-layer glass sash window into a heat insulating window of pair glass.

  The heat insulation method according to claim 3 is the heat insulation window method according to claim 1 or 2, wherein the transparent plate is a polycarbonate plate.

  That is, the invention according to claim 3 can be made into a heat insulating window by using a material that maintains transparency and has excellent heat insulating properties and is light in specific gravity and high in impact strength. For example, a polycarbonate plate having a thickness of 2 mm can be adopted.

  The heat insulation construction method according to claim 4 is the heat insulation window construction method according to claim 1, 2, or 3, wherein one or both surfaces of the transparent plate and / or one or both surfaces of the glass plate are coated with an ultraviolet cut film, It is characterized in that a smoke film or a heat reflection film is attached, or an ultraviolet cut coating process, a smoke coating process, or a heat reflection coding process is performed.

  In other words, the invention according to claim 4 makes it possible to provide a so-called hybrid eco window when an ultraviolet cut layer (part formed by a film or coating) is provided, and a smoke layer (formed by a film or coating). When a portion) or a heat reflecting layer (portion formed by a film or coating) is provided, it is possible to provide a window with further improved heat insulation.

  The heat insulation window structure of Claim 5 is a heat insulation window structure which has the same structure as the heat insulation window obtained by the heat insulation window conversion method as described in any one of Claims 1-4.

  That is, the invention according to claim 5 can easily provide a heat insulation window.

  According to the present invention, an existing single-layer glass sash window can be used as it is to easily form a heat insulating window.

It is a perspective explanatory view showing the structure of the sash window before and behind construction. It is sectional drawing showing the structure of the sash window before and behind construction. It is the whole figure after construction.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[Embodiment 1]
FIG. 1 is a perspective explanatory view showing the structure of a sash window before and after construction. FIG. 2 is a cross-sectional view illustrating a configuration of a sash window before and after construction. FIG. 3 is a full view after construction. For convenience of explanation, the scale of the aspect ratio is appropriately changed depending on the components.

  Before construction, the glass sash window 100 has a glass plate 101 and an aluminum sash frame 102. Each sash window frame 121 forming the four sides of the aluminum sash frame 102 has a concave cross section, and each end surface (side) of the glass plate 101 is inserted into the concave portion 122, and a resin sealing member 123 is formed. (In some cases, it may be a glass indentation bead material.)

  Although the magnitude | size of the glass sash window 100 is not specifically limited, For example, the thickness of the glass plate 101 can be 4 mm and the thickness of the aluminum sash frame 102 can be 2.0 cm.

  When the glass plate 101 is fixed by being inserted into the center of the aluminum sash frame 102, the distance from the surface of the glass plate 101 to the end of the aluminum sash frame 102 is only 8 mm. At this time, if the glass plate 101 having a thickness of 4 mm is further applied to the pair glass, the width to the end of the aluminum sash frame 102 is only 4 mm at maximum (in this case, the pair glass is in close contact), and the heavy glass. It is not suitable for inserting and fixing the plate 101.

  As a result of intensive studies, the inventor of the present application has developed a technique that enables a heat insulating window even in such a case. Here, a mode in which the resin sealing member 123 is used as it is will be described, but if it is deteriorated, it may be replaced with a new one as appropriate, and the mode described below is appropriately changed without being limited thereto. The workability can be ensured by doing so.

  First, before construction, prepare a measuring and framed polycarbonate plate. This is an operation for measuring the inner peripheral dimension of the target aluminum sash frame 102 and preparing a framed polycarbonate plate having a dimension obtained by subtracting the width (up and down, left and right) of the pressing rubber beads 133 to be fitted later.

  This polycarbonate plate with a frame is composed of a polycarbonate plate 103 and a dedicated aluminum frame 131. The dedicated aluminum frame 131 has a concave cross section, and is configured such that the polycarbonate plate 103 is inserted into the recess and a slight gap is opened. ing. In addition, a tubular rubber bead 132 is fitted in the gap, and serves as a packing to seal the polycarbonate plate 103 and absorb expansion and contraction of the polycarbonate plate 103 due to heat.

  As for the size of the framed polycarbonate plate, the outer shape is slightly smaller based on the above measurement. When the thickness of the glass plate 101 of the glass sash window is 4 mm, the thickness of the aluminum sash frame 102 is 2.0 cm, the thickness of the resin sealing member 123 is 1 mm, and the thickness of the polycarbonate plate 103 is 2 mm, the dedicated aluminum frame 131 is used. The thickness (depth) is 5 mm, the thickness (width or height of the frame) is 10 mm (of which the depth of the recess is 6 mm), the air layer is 1.5 mm to 1.9 mm, and the thickness of the caulking agent 125 is 1 mm to 2 mm. can do.

  At the time of construction, first, the indoor glass plate 101 is cleaned. Next, the framed polycarbonate plate prepared in the preparation is applied to the glass plate 101. Here, the dedicated aluminum frame 131 is brought into close contact with the glass plate 101, but may be floated by a predetermined amount via a spacer if necessary. A sealed air layer (heat insulating layer) is formed between the polycarbonate plate 103 and the glass plate 101. This low heat-transmitting polycarbonate plate and a sealed air layer improve heat insulation, and can improve cooling efficiency and heating efficiency.

  Next, the caulking agent 125 is thinly applied to the groove formed between the inner frame of the aluminum sash window frame 121 and the outer frame of the dedicated aluminum frame 131. Finally, a string-like presser rubber bead 133 having a tube structure with a thickness of about 3 mm to 5 mm is pressed and bonded along the groove. As a result, the aluminum sash frame 102, the resin sealing member 123, the glass plate 101, the dedicated aluminum frame 131, and the pressing rubber bead 133 are fixed, the air layer is sealed, and the framed polycarbonate plate is bonded to the glass plate 101 with high quality. And a pair glass will be constructed.

  The polycarbonate plate has a heat transmission rate as low as 36% to 46% compared to glass, is light compared to glass, and has an impact strength 200 times that of glass. Therefore, if a polycarbonate plate is used, even if it is thinner than a glass that does not have high heat insulation, impact resistance is ensured, accident prevention due to glass breakage is ensured, and light weight can be realized because it is originally a light material. Considering this point, in the present embodiment, the thickness of the polycarbonate plate 103 is set to 2.0 mm.

  Since the weight can be reduced by using the polycarbonate plate 103, the load on the caulking agent 125 and the pressing rubber bead 133 is reduced. That is, the structural reliability is improved by using the polycarbonate plate 103.

  Alternatively, all of the resin sealing member 123 (glass pressing bead material) may be peeled off and replaced with the pressing rubber bead 133. In consideration of design, the pressing rubber bead 133 may be a color rubber, for example, a bright blue rubber.

  In addition, as shown in the entire appearance (FIG. 3), a moisture absorbing sheet 105 may be attached to the corner of the air layer portion above the crescent 104 to adsorb moisture accumulated inside. At this time, the glass plate 101 on the indoor side and the resin sealing member 123 on the indoor side are cleaned and dried, and the moisture absorbing sheet 105 is adhered to the frame corner on the crescent 104 side. The number or area of the hygroscopic sheet 105 to be attached is appropriately determined depending on the size of the glass plate 101.

  The present invention is not limited to the above embodiment. For example, the polycarbonate plate 103 is disposed on the indoor side, but the polycarbonate plate 103 may be disposed on the outdoor side depending on the mode of use.

  Moreover, you may make it form a multifunctional pair glass window by performing heat reflection film sticking and heat reflection paint coating.

  According to the present invention, it is possible to use an existing single-layer glass sash window as it is to make a hybrid eco-glass window.
