Description

  The present invention relates to a technique for changing a window with a single-layer glass into a window with a double-layer glass, and more specifically, a double-layer glass used for mounting a double-layer glass on a single-layer glass bottle. The present invention relates to a glazing gasket for use, a multilayer glass provided with the glazing gasket, a shoji equipped with the multi-glazed glass, a window fitted with the shoji, and a method for attaching the multi-glazed glass to a single-glazed glass bottle.

  A window of a building is configured by mounting a shoji composed of a fence and a glass plate on a window frame made of aluminum or the like. This shoji is constructed by incorporating a glass plate into the wide open side of a ridge formed in a frame shape so as to surround the upper, lower, left and right four circumferences. That is, as shown in FIG. 11, the ridge 131 is formed using a frame material having a substantially H-shaped cross section having a concave groove 132 along the longitudinal direction, and a glass plate is mounted in the groove. It has become a thing.

  When a glass plate is attached to the heel, in order to maintain the watertightness between the heel and the glass plate and to securely fix the glass plate to the heel, a buffer material and an end surface (peripheral portion) of the glass plate are used. A glazing gasket is interposed as a sealing material. This glazing gasket is formed of a synthetic resin material such as polyvinyl chloride or a rubbery elastic material such as synthetic rubber (for example, silicone rubber), and a pair of rising portions are integrally formed via the bottom portion. A glazing channel having a substantially U-shaped cross section and a glazing beat in which a pair of rising portions are separated are known.

  Conventionally, in windows configured in this manner, condensation of window glass that occurs in winter has become a major problem. That is, in winter when the outside air temperature falls, warm indoor air touches the window glass cooled by cold outdoor air, and water vapor contained in the indoor air adheres to the window glass as water droplets. Become.

In view of this, various types of double-glazed glass have been proposed as countermeasures against the condensation of such window glass (see, for example, Patent Documents 1 to 3).
As shown in FIG. 12, the basic structure of the double-glazed glass 121 is such that a primary sealing material 124 made of a rubber-like elastic body is interposed between two glass plates 122 and 122 arranged to face each other. By disposing the spacer 123, an internal space (hollow layer) 126 surrounded by the two glass plates 122 and 122 and the spacer 123 is formed. The multi-layer glass 121 is filled with a secondary sealant 125 made of a rubber-like elastic body in the outer edge opening formed by the two glass plates 122 and 122 and the spacer 123, and the outer edge of the two glass plates. The open space is sealed. Thereby, even if an outer side glass is cooled, the inner side glass which touches indoor air becomes difficult to cool by the heat insulation effect of the hollow layer 126, and it can be set as a thing which does not produce dew condensation on a window glass easily.

  However, even if double glazing is known to be desirable, replacing existing windows with single glazing with windows with double glazing requires renovation of the building, including window frame replacement. It will be time consuming and expensive. That is, as shown in FIGS. 11 and 12, the opening dimension T1 of the groove 132 in the ridge 132 on which the single-layer glass is mounted is smaller than the thickness T2 of the multilayer glass 121 (T1 <T2), and the ridge 132 The opening edge portion 133 becomes an obstacle and the double glazing 121 cannot be incorporated in the concave groove 132.

  Therefore, in order to change a window with a single-layer glass into a window with a double-layer glass, it takes a large amount of work such as changing the window frame itself, and high costs. Unless there are special circumstances, such as under the environment where it is necessary to prevent condensation, windows fitted with double glazing are not widely used.

  Therefore, as means for changing an existing window on which a single-layer glass is attached to a window on which a double-layer glass is attached, means using an adapter that holds the double-glazing (see, for example, Patent Document 4), 2 Means using a special spacer for sandwiching a glass plate (for example, refer to Patent Document 5), means for mounting a heat insulating sheet or a transparent synthetic resin plate with a space on the surface of the glass plate (for example, Patent Document 6 to 10) have been proposed.

  However, the means using the adapter is to attach the adapter attached to the outer peripheral part of the double-glazed glass to be attached to the inside of the bag, so that the visible region and the light transmission region in the window are narrow by the amount of the adapter attached. It becomes a thing.

  In addition, the means using the spacer requires a spacer having a special structure different from the spacer attached to the multilayer sash having the existing structure, and the multilayer glass having a structure different from the multilayer glass having the existing structure is required. It must be made and cannot be easily changed to a window fitted with double glazing.

  Furthermore, the means of attaching a heat insulating sheet or a transparent synthetic resin plate with a space on the surface of the glass plate can be easily changed to a window with a double-layer glass attached, but a sealed internal space (intermediate Layer) cannot be formed, and sufficient heat insulation effect cannot be expected.

In the step C, the convex portion of the glazing gasket is inserted into the opening of the concave groove in the ridge, and the thick portion of the glazing gasket is formed in the concave groove of the ridge. The double-glazed glass with a glazing gasket is attached to the ridge in a state of being brought into contact with the opening edge.

  In the above-described method for attaching the double-glazed glass to the single-glazed glass bottle, following the step C, the same as the glazing gasket between the double-glazed glass and the double-glazed glass (that is, outside the thick portion). It is desirable to further include a process D for filling a sealing material made of a material.

  Further, in the above-described method for attaching a double-glazed glass to a single-glazed glass bottle, after the step B, before the step C, the thickened portion of the glazing gasket disposed on the bottom side of the double-glazed glass Furthermore, it is good also as a thing further equipped with the process (alpha) which apply | coats the cladding material which consists of the same material as the said glazing gasket so that thickness may increase.

  Further, in the above-described method for mounting the double-layer glass on the single-layer glass bottle, instead of the step B, a convex portion having a substantially trapezoidal cross-section using a glazing gasket molding material is used in the step A. Forming along each end face on the outer periphery of the prepared multi-layer glass, and having a step X for producing a multi-layer glass with a glazing gasket, in the step X, the end surface side of the multi-layer glass on the side surface of the convex portion It is good also as what forms a thick part.

The glazing gasket of the present invention has a convex portion protruding on the back side of the joint surface to be attached along the outer peripheral end surface of the multilayer glass, and a thick portion on the joint surface side of the side surface of the convex portion. is doing.
Therefore, even when the opening size of the groove for inserting the glass plate in the ridge is smaller than the thickness of the end face of the multilayer glass, the outer periphery of the multilayer glass cannot be inserted into the groove, so that the gray If the ging gasket is attached along the outer peripheral end face of the double-glazed glass, the double-glazed glass can be easily attached to the bag on which the single-glazed glass has been attached.

Attaching the double-glazed glass to the ridge where the single-layer glass was mounted, regardless of the opening width of the groove of the ridge and the width of the end face of the double-glazed glass Is possible.

In addition, the outer peripheral portion of the double-glazed glass is not inserted into the concave groove of the glazed glass, and the thickened portion of the glazing gasket of the present invention is interposed (between) It is supposed to contact (place) the opening edge.
Therefore, the visible area and light transmission area in the window are not narrowed by the glazing gasket, and the glazing gasket acts as a cushioning material so that the end face of the multilayer glass is elastically connected to the opening edge of the glazing. Therefore, it is possible to suppress (reduce) the possibility that the multi-layer glass is cracked by vibration or impact. Moreover, the glazing gasket interposed between the double-glazed glass and the glazing works not only as a cushioning material but also as a heat insulating material, and is less affected by the temperature difference between the double-glazed glass and the glazed glass, and the double-glazed glass may be thermally cracked. Can also be suppressed (reduced).

  In addition, when the double-glazed glass fitted with the glazing gasket of the present invention is attached to the bag, the double-glazed glass is required in the lower glass portion where the most tightness is required in order to suppress the intrusion of rainwater or condensed water. Since the thick portion is constantly pressed by its own weight, it is possible to achieve a suitable one with more increased sealing performance.

  Furthermore, since the glazing gasket of the present invention is attached to a multi-layer sash having an existing structure, it is not necessary to manufacture a multi-layer glass having a new structure, and a sufficient heat insulating effect can be expected.

  Therefore, without reducing the visible area and light transmission area of the double-glazed glass, using the double-glazed glass of the existing structure, the window with the single-glazed glass is easily changed to the window with the double-glazed glass. It is possible to provide a technique that can be used.

Although the embodiments described below are preferred specific examples of the present invention, various technical limitations are applied. However, the scope of the present invention is described as being particularly limited in the following description. As long as it is not, it is not restricted to these forms.

  As shown in FIG. 1, a glazing gasket for multilayer glass (hereinafter simply referred to as “glazing gasket”) 10 in the present embodiment is a saddle (hereinafter referred to as “single layer glass”) on which a single layer glass is mounted. It is a glazing gasket that is used to mount a double-glazed glass, and includes a wide joint surface 11, a narrow convex portion 12, and a thick portion 14. That is, the glazing gasket 10 is an elastic member made of a long body having a substantially trapezoidal cross section along the short side direction, and has a new structure in a sealing member called a so-called glazing channel. It can be said.

The joint surface 11 is a part to be attached along the outer peripheral end surface 27 of the multilayer glass 21 described later.
Moreover, the convex part 12 protrudes in the back surface side of the joint surface 11, and is a site | part which will be inserted in the opening of the ditch | groove 32 in the ridge | line | mouth (single layer glass ridge) 31 mentioned later.
Furthermore, the thick portion 14 is a portion that is located on the side of the joint surface 11 on the side surface 13 of the convex portion 12 and that comes into contact with the opening 31 of the groove 32 in the flange 31. .

  The glazing gasket 10 has a function of preventing water from entering into the double-glazed glass due to physical adhesion with the double-glazed glass 21. For example, a silicon-based or polysulfide-based rubber material is used. It can be formed of an elastic material.

  Although not shown, a glazing gasket 10 in which a core material having a square shape, a square shape, or an H shape is disposed inside the convex portion 12 may be used. Thereby, the intensity | strength of the convex part 12 inserted in the opening of the ditch | groove 32 in the collar 31 increases, and it can be set as the window where the multilayer glass was mounted | worn stably.

Moreover, the glazing gasket 10 can be made into the multilayer glass 20 with a glazing gasket according to the present embodiment by being attached along the outer peripheral end face 27 of the multilayer glass 21, as shown in FIG. This double-glazed glass with a glazing gasket 20 is a double-glazed glass that can be attached to the bottle 31 to which the single-layer glass has been attached. It is comprised from the glazing gasket 10 attached along the outer peripheral end surface 27 of the multilayer glass 21 formed smaller than this multilayer glass 21, and.
In FIG. 2, the double-glazed glass 20 with the glazing gasket in a state where the glazing gasket 10 is continuously and integrally attached to the outer peripheral end surface 27 of the double-layer glass 21 is shown.

Moreover, as shown in FIG. 3, the double-glazed glass 20 with a glazing gasket obtained in this way can be used as the shoji 30 according to the present embodiment by being mounted on the single-glazed glass ridge 31. it can. This shoji 30 is a shoji in which a double-glazed glass 31 is mounted on a single-glazed glass bowl 31 and, as will be described later, is smaller than the inner and vertical dimensions of the single-layer glass bowl 31 and the single-layer glass bowl 31. The multilayer glass 21 is formed, and the glazing gasket 10 attached along the outer peripheral end surface 27 of the multilayer glass 21.
In FIG. 3, the shoji 30 is shown in a state in which the double-glazed glass 20 with the glazing gasket attached with the glazing gasket 10 along the outer peripheral end surface 27 of the double-glazed glass 21 is attached to the single-glazed glass ridge 31. .

Moreover, the shoji 30 obtained in this way can be made into the window 40 which concerns on this Embodiment by mounting | wearing the window frame 41, as shown in FIG. The window 40 is a window in which the shoji 30 in which the double-glazed glass is fitted is mounted on the window frame 41 in which the shoji in which the single-layer glass is fitted is fitted, and the single-layer glass is fitted as will be described later. A window frame 41 on which the shoji is mounted, a single-layer glass casket 31, a multi-layer glass 21 formed smaller than the inner vertical and horizontal dimensions of the single-layer glass casket 31, and an outer peripheral end face 70 of the multi-layer glass 21 The glazing gasket 10 is attached along
In FIG. 4, the shoji 30 in which the glazing gasket-attached double glazing glass 20 with the glazing gasket 10 attached along the outer peripheral end face 27 of the double glazing 21 is attached to the inner side of the window frame 41. The windows 40 are shown attached to the outside.

Next, a method for attaching the double-glazed glass to the bag on which the single-glass is attached will be described.
First, as shown in FIG. 5, a multi-layer glass 21 formed smaller than the inner vertical and horizontal dimensions of the single-layer glass jar 31 is prepared (step A).
The multilayer glass 21 may be requested to be manufactured in advance by a manufacturer of the multilayer glass so as to have a predetermined size, and the peripheral edge of the manufactured multilayer glass is cut off to a predetermined size. Later, it may be reassembled. Moreover, although it takes time, it is good also as what manufactures newly by reusing the single-layer glass with which the single-layer glass bottle was mounted | worn.

  In FIG. 5, the multilayer glass 21 in which the vertical and horizontal dimensions (H2 × W2) are smaller than the inner vertical and horizontal dimensions (H1 × W1) of the single-layer glass bowl 31 is shown. That is, the vertical dimension H2 of the double-glazed glass 21 is smaller than the inner vertical dimension H1 of the single-glass glazing 31 (H2 <H1), and the horizontal dimension W2 of the double-glazed glass 21 is the inner horizontal dimension of the single-glass glazing 31. It is smaller than the dimension W1 (W2 <W1).

  Next, as shown in FIG. 6, the glazing gasket 10 according to the present embodiment is attached along each end face 27 on the outer periphery of the multi-layer glass 21, and the glazing gasket-attached composite as shown in FIG. The layer glass 20 is manufactured (process B).

  The multilayer glass 21 used in the production of the multilayer glass 20 with the glazing gasket is not particularly limited, and a multilayer glass having an existing structure can be used. For example, as shown in FIG. 6, the double-layer glass having an existing structure has two glass plates 22, 22 opposed to each other with a spacer 23, and the glass plate 22 and the spacer 23 are used as a primary sealing material 24 in a butyl system. The inner space (hollow layer) 26 surrounded by the two glass plates 22 and 22 and the spacer 23 is shut off from the outside air. Thereafter, the gap formed by the inner surface of the opposing glass plate 22 and the outer periphery of the spacer 23 is sealed as a secondary sealing material 25 with a room temperature curable sealing material such as polysulfide or silicon. What is done is known. The spacer 23 contains a hygroscopic material.

The glazing gasket 10 is attached to the multilayer glass 21 by attaching the joining surface 11 so that the glazing gasket 10 is put on the outer peripheral end surface 27 of the multilayer glass 21.
At this time, when the glazing gasket 10 is attached to the outer peripheral end surface 27 of the multilayer glass 21 using an adhesive made of the same material as that of the glazing gasket, the glazing gasket 10 is integrally bonded to the outer peripheral end surface 27 of the multilayer glass 21. This is desirable.

  Further, the glazing gasket 10 is formed using the same material as the secondary sealing material 25 in the multilayer glass 21, and the outer peripheral end face 27 of the multilayer glass 21 is formed using an adhesive made of the same material as the secondary sealing material 25. It is desirable to attach the glazing gasket 10 to the secondary seal material 25 because the secondary sealing material 25 and the glazing gasket 10 are integrally joined.

  Moreover, it is desirable that the connecting portion at the start and end of the glazing gasket 10 is also sealed with a sealing material made of the same material as the glazing gasket.

  At this time, without using the pre-shaped glazing gasket 10, convex portions having a substantially trapezoidal cross section using a glazing gasket molding material are continuously provided along each end face 27 on the outer periphery of the multilayer glass 21. It is good also as what manufactures and forms the multilayer glass 20 with a glazing gasket (process X). In addition, this convex part 12 shall form the thick part 14 in the end surface 27 side of the multilayer glass 21 in the side surface 13. As shown in FIG.

Then, as shown in FIG. 7, the single-layer glass is removed from the single-layer glass jar 31, and the manufactured double-glazed glass 20 with a glazing gasket is attached to the single-layer glass jar 31 (process C).
When the glazing gasket-attached double glazing 20 is attached to the single glass glazing 31, the convex portion 12 of the glazing gasket 10 is inserted into the opening of the concave groove 32 in the single glazing glazing 31 and gray. It is assumed that the thick portion 14 of the ging gasket 10 is brought into a contact state so as to be placed on the opening edge portion 33 of the groove 32 in the single-layer glass ridge 31.

  Then, as shown in FIG. 8, the multi-layer glass 20 with the glazing gasket is deformed while the side surface 13 of the glazing gasket 10 is in contact with it, and the thick portion 14 is placed on the opening edge portion 33. The layer glass 21 is attached to the single-layer glass bowl 31 regardless of its thickness dimension. That is, the outer peripheral end surface 27 of the multilayer glass 21 is incorporated so as to be placed on the opening edge portion 33 of the single-layer glass bottle 31 through the thick portion 14 of the glazing gasket 10 that is an airtight material. Become.

  At this time, the convex part 12 of the glazing gasket 10 is inserted into the opening of the concave groove 32 in the single-layer glass jar 31 so that the double-glazed glass 20 with the glazing gasket is transferred to the single-layer glass jar 31. It functions as a guide for mounting and can easily position the double-glazed glass 20 with the glazing gasket with respect to the single-glazed glass rod 31.

  Further, in the method according to the present invention, as shown in FIG. 9, after the double-glazed glass 20 with the glazing gasket is attached to the glazing 31 for single-layer glass (step C), It is good also as what fills with the sealing material 34 which consists of the same material as the glazing gasket 10 between the cage | baskets 31 for single layer glass (process D).

  That is, the thickness of the multilayer glass 21 varies depending on the thickness of the glass plate 22 used for the multilayer glass 21 and the thickness of the partial space (hollow layer) 26 provided between the two glass plates 22 and 22. There is. Therefore, depending on the multi-layer glass 21, as shown in FIG. 9A, the width dimension of the joining surface 11 of the glazing gasket 10 is smaller than the thickness dimension of the outer peripheral end surface 27 of the multi-layer glass 21, A gap 35 may be generated outside the thick portion 14. At this time, as shown in FIG. 9B, the gap 35 is filled with a sealing material 34 made of the same material as the glazing gasket 10.

  Thereby, if the glazing gasket 10 having a predetermined dimension is prepared in advance, the glazing gasket 10 is attached without worrying about the thickness dimension of the outer peripheral end surface 27 of the multilayer glass 21, and the multilayer glass 21 is later installed. The dimension of the glazing gasket 10 can be adjusted in accordance with the thickness dimension of the outer peripheral end surface 27 of the glazing.

  Furthermore, in the method according to the present invention, as shown in FIG. 10, after the glazing gasket 10 is attached to the multi-layer glass 21 (step B), the multi-layer glass 20 with the glazing gasket is attached to the single-layer glass cage 31. Prior to mounting (step C), a build-up material 15 made of the same material as the glazing gasket is applied to the thick portion 14 of the glazing gasket 10 disposed on the bottom side of the multilayer glass 21 so as to increase the thickness. It is good also as what to do (process alpha).

  That is, when the double-glazed glass 20 with the glazing gasket is attached to the single-glazed glass bowl 31, the thick portion 14 of the glazing gasket 10 disposed on the bottom side is crushed by the weight of the double-glazed glass 21 and is sufficiently thick. May not be able to maintain. At this time, the overlaying material 15 made of the same material as that of the glazing gasket is applied so as to overlap the thick portion 14 of the glazing gasket 10 disposed on the bottom side of the multilayer glass 21 in advance.

  Thereby, in order to suppress the intrusion of rainwater, condensed water, etc., it is possible to make the airtightness more suitable on the bottom side of the double glazing 21 where the airtightness is most required. Moreover, the thick part 14 which apply | coated the cladding material 15 functions as a more suitable buffer material, and the end surface 27 of the multilayer glass 21 will be in elastic contact with the opening edge part 33 of the basket 31 for single layer glass. Therefore, it is possible to further suppress (reduce) the possibility that the multi-layer glass 21 is cracked due to vibration or impact. In addition, the thick portion 14 to which the overlaying material 15 is applied functions not only as a buffer material but also as a heat insulating material, and is less affected by the temperature difference between the multilayer glass and the glazing, and the multilayer glass may be thermally cracked. It can be further suppressed (reduced).
