Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for supporting plate glass in a blind window installed in an opening in an exterior wall of a building.

[Prior art and its problems]

Traditionally, when installing plate glass to an opening in a building's exterior wall, a method was used to attach it via metal sashes, but recently a method using zipper gaskets that uses molded rubber as the glazing material, which is easy to install, has been used. Often used. In the former method, which uses metal sashes, elastic sealants are used on both sides of the glass plate, but elastic sealants facing outdoors deteriorate due to ultraviolet rays from sunlight, so the sealant must be reapplied at regular intervals. The repair work required a lot of time and manpower, and the work was dangerous because it required an external hanging gondola. In order to satisfy the latter requirement of construction using a zipper gasket, it is necessary to manufacture and construct the mounting support material with high precision. However, plate glass has some deformations such as warping and twisting.
Furthermore, although the molded rubber used as the glazing material has flexibility, there are some manufacturing errors, and there are also some manufacturing errors in the grooves for attaching the plate glass in the opening. These deformations and manufacturing errors remain in the glass plate as stress when the glass plate is attached, resulting in a disadvantage that the glass plate is likely to break.
Also, in this method using a zipper gasket, it is necessary to replace the zipper gasket at regular intervals, resulting in the same problem as the former method, which involves repair work.

[Purpose of the invention]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a method for supporting a glass plate in a fill-in window, which extends the service life of the sealant, reduces breakage of the glass plate, and facilitates safety and maintenance work.

[Means for solving problems]

In order to solve the above-mentioned problems, the method for supporting plate glass in a fitted window of the present invention is provided all around the opening in the molded material for the exterior of a building, and one end of the drain pipe is opened at the bottom of the opening. An elastic sealant is applied to the required thickness on the outdoor side wall surface of the groove for attaching plate glass, and a sheet-shaped elastic material with excellent light resistance and light shielding properties is attached onto the elastic sealant, and the elastic sealant is cured. The glass plate is inserted into the groove and pressed against the sheet-like elastic material before the glass plate is exposed to the groove, and spacers are inserted between the four circumferences of the glass plate and the bottom of the groove to position the glass plate vertically and horizontally. One end of the L-shaped ridge is attached to the inner opening, and a shaped sealant is sandwiched between the other end and the indoor wall surface of the groove, and then the other end of the ridge and the peripheral area of the plate glass are inserted. This method involves inserting a back-up material between the two and filling it with an amorphous sealant.

[Effect]

In the above means, the elastic sealing material interposed between the outdoor side wall surface of the groove and the outdoor surface of the plate glass hardens in accordance with the shape between both surfaces, and the elastic sealing material is hardened to follow the shape between the two surfaces, and the sealing material is hardened to follow the shape between the two surfaces. The amorphous sealing material interposed between the two similarly hardens to follow the shape between the two.

Furthermore, sunlight that enters from the outdoor surface of the plate glass and is reflected on the indoor surface is blocked by the sheet-like elastic material, so that the elastic sealing material is not exposed to sunlight.

Furthermore, it becomes possible to perform work such as replacing plate glass or repairing work such as applying an elastic sealant from the indoor side.

〔Example〕

One embodiment of the present invention will be explained based on the drawings. Fig. 1 is a cross-sectional view of the vicinity of the lower side of the opening in the exterior molding material, and Fig. 2 is a cross-sectional view of the vicinity of the side or upper side thereof. .

In the figure, 1 is the exterior molding material, 2 is the opening, and 3
is a groove for attaching a plate glass, and is provided along the entire length of the opening. One end of the drain pipe 5 is opened at the bottom of the groove 3 on the lower side of the opening 2, and the other end is opened at the side surface of the vertical joint (not shown). In the exterior molded material 1, support inserts 22, 23 are fixed to anchor bars 24 and embedded in the opening 2 on the indoor side 21 from the groove 3, and the support plate 25, parting edge 26 and interior board 27 are embedded in advance is attached with bolts, screws, and adhesive 28.

First, the groove 3 of the opening 2 in the exterior molding material 1
An elastic sealing material 7 that becomes an elastic body after curing is applied to the outdoor side wall surface to a required thickness, and a sheet-like elastic material 8 with excellent light resistance and light blocking properties is attached to the upper surface of the elastic sealing material 7, and the elastic sealing material 7 is cured. The glass plate 4 is inserted into the groove 3 and pressed against the sheet-like elastic material 8 before the glass plate 4 is inserted, and a rectangular parallelepiped spacer 6 made of hard rubber is interposed between the four circumferences of the glass plate 4 and the bottom of the groove 3, and the glass plate 4 is inserted into the groove 3 and pressed against the sheet-like elastic material 8. 4. Perform vertical and horizontal positioning.

Next, from the groove 3 to the opening of the indoor side 21, one end of the L-shaped ridge 10 is inserted into a wedge-shaped pair of spacers 11.
At the same time, a shaped sealing material 9 is sandwiched between the other end of the ridge 10 and the indoor wall surface of the groove 3. The spacer 11 is the plate glass 4 of the rim 10.
The height of engagement with the groove 3 is adjusted, and the regular sealing material 9 seals the interior of the room against the bottom of the groove 3 in cooperation with an irregularly shaped sealing material, which will be described later.

A back-up material 12 is inserted between the other end of the rear rim 10 and the periphery of the glass plate 4, and an amorphous sealing material 13 is filled thereon. Then, after the elastic sealing material 7 and the irregularly shaped sealing material 13 have hardened, the frame 29 is attached to the indoor side 21, and the work is completed.

The method described above assumes that the exterior molding material 1 is temporarily placed with the outdoor side 20 facing downward before the plate glass 4 is attached.
If measures are taken to prevent the sheet-like elastic material 8 from drooping or slipping down, the work may be carried out with the exterior molding material 1 erected vertically.

〔Effect of the invention〕

As described above, according to the present invention, the elastic sealing material interposed between the outdoor side wall surface of the groove and the outdoor surface of the plate glass hardens in accordance with the shape between both surfaces, and the elastic sealing material is hardened to follow the shape between the two surfaces, and Since the amorphous sealing material interposed between the other end similarly hardens by following the shape between the two, there is no possibility that stress will be generated in the glass sheet due to deformation of the glass sheet or manufacturing errors in the supporting material, as in the past. Since the glass plate is supported by the exterior molding material without any damage, breakage of the glass plate can be reduced.

In addition, the sheet-like elastic material blocks sunlight that enters the outdoor surface of the plate glass and reflects on the indoor surface, and the elastic sealant is not exposed to sunlight, preventing its deterioration and improving its elasticity. The service life of the sealant can be extended.

Furthermore, since it becomes possible to perform work such as replacing plate glass and repair work such as elastic sealing material from the indoor side, there is no need to prepare an external hanging gondola, and maintenance work can be performed easily and safely.
