Description

  The present invention relates to a structure for preventing condensation by thermally insulating a new or existing glass window.

  Various proposals have heretofore been made as structures for preventing condensation by newly insulating or existing glass windows, and most of them have a structure as shown in Patent Document 1, for example.

  The structure shown in Patent Document 1 is as shown in FIG. 7. In FIG. 7, 100 is an existing glass window, 101 is a window frame, and 102 is fitted to the window frame 101 through a packing 103. It is a plate glass. Then, on the indoor side of the plate glass 102 of the glass window 100, a strip-like spacer 104 having a predetermined thickness arranged along the inner periphery of the window frame 101 and an appropriate spot in the center of the plate glass 102 are spot-arranged. A transparent or translucent resin panel 106 covering the entire surface of the plate glass 102 is attached via the spacer 105 having a predetermined thickness, and a heat insulating air layer 107 is formed between the plate glass 102 and the resin panel 106. It is the structure which becomes. The spacer 104 is bonded with a double-sided adhesive tape (not shown).

JP 2004-76545 A

  According to such a structure, since the heat insulating air layer 107 is formed between the plate glass 102 and the resin panel 106, dew condensation can be prevented. However, such a conventional structure also has the following problems. That is, since all the four peripheral edges of the resin panel 106 are fixed in an immobile state, the resin panel 106 cannot cope with the deformation when the resin panel 106 expands or contracts due to a change in indoor temperature. That is. In addition, since the spacer 104 is bonded to the plate glass 102 and the resin panel 106 with a double-sided adhesive tape (not shown), it takes considerable labor and time for installation, and once set, the resin can be easily used. There is also a problem that the panel 106 cannot be removed. In this case, when dust, insects, or the like enter the heat insulating air layer 107, or both or one of the plate glass 102 and the resin panel 106 become dirty or damaged, this is easily handled. It will not be possible. Furthermore, when the spacer 104 is bonded with a double-sided adhesive tape, the adhesive force is weakened due to the influence of sunlight and temperature, and the resin panel 107 may be peeled off. This is particularly noticeable when installed on south and west windows, which are hot during summer.

  The present invention has been made in view of the above points, and even if the resin panel expands or contracts due to temperature change, it can cope with this, and can be installed easily and quickly. In addition to being able to do this, the resin panel can be easily removed even after it has been set, and in addition, it is not affected by sunlight or temperature, and can be stably installed for a long time. It is intended to provide a glass window insulation and condensation prevention structure.

  Thus, the gist of the present invention is that a transparent or translucent resin panel covering the entire surface of the glass sheet is provided on the indoor side and / or the outdoor side of the glass sheet of the glass window via a spacer having a predetermined thickness. In the heat insulation and dew condensation prevention structure of the glass window formed by sealing the periphery of the resin panel and forming a heat insulation air layer between the plate glass and the resin panel, the spacer is appropriately placed at the center of the resin panel. Consists of an internal spacer that is spot-arranged at the location and a strip-shaped external spacer made of sponge, rubber, etc. that is arranged along the periphery of the resin panel. By inserting a clip in which an L-shaped receiving part is coupled to the front end of the part toward the opposite side of the insertion part, and inserting the insertion part between the packing that seals the periphery of the plate glass and the plate glass Installed at appropriate positions on the upper and lower and left and right sides of the inner periphery of the window frame, at least the left and right and lower peripheral portions of the resin panel, between the end surface and the inner bottom surface of the L-shaped receiving portion in the clip, The glass is characterized in that the resin panel is fitted with an interval that can cope with expansion / contraction deformation due to a temperature change, and is further covered with a sealing tape that covers the entire periphery of the resin panel. Insulated windows and anti-condensation structure.

  Moreover, in the said structure, it is preferable that an internal spacer is made into the internal spacer which gave adhesive force to both surfaces with the adhesive tape or the suction cup.

  The present invention is configured as described above, and the resin panel has at least the left and right peripheral edges thereof and a swelling due to a temperature change of the resin panel between the end surface and the inner bottom surface of the L-shaped receiving portion of the clip. The belt-like external spacers that are inserted along the peripheral edge of the resin panel are elastic and made of sponge, rubber, etc. Even if the panel expands or contracts due to a change in temperature, it can cope with this. In addition, since the resin panel is held by a clip that inserts the insertion portion between the packing that seals the periphery of the plate glass and the plate glass, the resin panel is also installed by a conventional double-sided adhesive tape. It is much easier and quicker than that. Similarly, the resin panel can be easily removed even after being set once. In addition, since the resin panel is held on the inner surface of the plate glass with a clip made of spring material, it is not affected by sunlight or temperature as in the case of using a conventional double-sided adhesive tape, and can be installed stably for a long period of time. It can be maintained.

  Further, when the internal spacer is an internal spacer having adhesive force on both sides by an adhesive tape or a suction cup, warpage due to a temperature change of the resin panel can be suppressed.

It is the state figure seen from the indoor side before the heat-insulation of the glass window which concerns on embodiment of this invention, and the sealing combined use decorative tape of a dew condensation prevention structure. It is a partial expanded sectional view. It is a perspective view of an internal spacer. It is a perspective view of the other example of an internal spacer. It is a perspective view of a clip.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

  In the figure, 1 is an existing glass window. The glass window 1 is formed by fitting a plate glass 4 on a window frame 2 of an aluminum sash through a packing 3.

  Reference numeral 5 denotes a transparent or translucent resin panel attached to the interior side of the plate glass 4 in the glass window 1 via a spacer described later. The resin panel 5 covers the entire indoor surface of the plate glass 4 and forms a heat insulating air layer S between the plate glass 4 and the resin panel 5. The resin panel 5 uses an acrylic plate in this embodiment. Further, the thicker the insulating air layer S is, the more effective, and it is desirable to make it as thick as possible.

  Reference numeral 6 denotes an internal spacer interposed between the plate glass 4 and the resin panel 5, and in the present embodiment shown in FIG. 3, it is made of a resin having a transparent or translucent elasticity, and has a predetermined thickness (this In the embodiment, it is 3 mm) and is formed into a disk shape. Moreover, the adhesive tape 6A is stuck on both surfaces, and the adhesive force is given. The internal spacers 6 are arranged in spots at approximately 30 cm intervals at appropriate locations in the center of the resin panel 5. The arrangement of the internal spacers 6 is determined according to the size of the plate glass 4 and the resin panel 5, and in the illustrated example, the case where three pieces are arranged vertically in the center is shown. However, the present invention is not limited to this, and is appropriately determined. Further, as the internal spacer, as shown in FIG. 4, suction force may be provided by providing suction cups 6b and 6b on both sides of the cylindrical main body 6a.

  Reference numeral 7 denotes a belt-like external spacer disposed along the periphery of the resin panel 5 interposed between the plate glass 4 and the resin panel 5. The external spacer 7 has elasticity made of sponge, rubber or the like. Moreover, the thickness is the same as that of the internal spacer 6.

  Reference numeral 8 denotes a clip installed at appropriate positions on the upper and lower sides and the right and left sides of the inner periphery of the window frame 2. The clip 8 is made of a stainless spring material, and an L-shaped receiving portion 8b is coupled to the front end of the insertion portion 8a toward the opposite side of the insertion portion 8a. The insertion portion 8 a is installed by being inserted between the packing 3 that seals the periphery of the plate glass 4 and the plate glass 4. Further, when the resin panel 5 is inserted into or removed from the L-shaped receiving portion 8b, the elasticity of the clip 8 made of a spring material and the elasticity of the resin panel 5 are used to warp them with a spatula tool. To do.

  The clip 8 and the resin panel 5 have at least left and right peripheral edges of the resin panel 5 between the end surface and the inner bottom surface 8b 'of the L-shaped receiving portion 8b of the clip 8. The resin panel 5 is inserted with an interval L that can cope with expansion / contraction deformation due to temperature change.

  Reference numeral 9 denotes a sealing / decorative tape that is applied over the entire periphery of the periphery of the resin panel 5 including the clip 8. The sealing / decorative decorative tape 9 is preferably of the same color as the window frame 2, and is applied using a heat-sealing agent applied to the back surface or a strong adhesive that does not require heat.

Next, the operation of this embodiment will be described.
Resin panel 5 corresponds to expansion / contraction deformation due to temperature change of resin panel 5 at least between its left and right peripheral edges and between its end face and inner bottom surface 8b 'of L-shaped receiving portion 8b of clip 8 Since the belt-like external spacer 7 that is fitted along the periphery L of the resin panel 5 has elasticity and is made of sponge, rubber, etc. Even if 5 is deformed by expansion or contraction due to a temperature change, this can be dealt with. Further, the resin panel 5 is held by the clip 8 that is inserted and set between the packing 3 that seals the periphery of the plate glass 4 and the plate glass 4. Therefore, the resin panel 5 is also installed by a conventional double-sided adhesive tape. It is much easier and faster than doing it. Similarly, the resin panel 5 can be easily removed even after being set once. In addition, since the resin panel 5 is held on the inner surface of the plate glass 4 with the clip 8 made of a spring material, it is not affected by sunlight or temperature as in the case of using a conventional double-sided adhesive tape, and is stable for a long time. The installation state can be maintained. Moreover, since the internal spacer 6 has adhesive force on both sides by an adhesive tape or a suction cup, warping due to a temperature change of the resin panel 5 can be suppressed. Furthermore, when the plate glass 4 is broken by an earthquake or an impact, it can be prevented from scattering into the room, and it is difficult to enter from the window, so that a crime prevention effect can be expected.

  Moreover, although the said embodiment is a case where the resin panel 5 is attached to the room inner side of the plate glass 4 in the glass window 1, although not illustrated, the resin panel 5 is attached to the chamber of the plate glass 4 although not illustrated. You may make it attach to an outer side, Furthermore, you may make it attach to both the indoor side and the outdoor side of the plate glass 4. FIG. What is necessary is just to select these suitably according to the condition of a cold district or a window frame. The specific structure is the same as that of the present embodiment, and detailed description thereof is omitted.
