Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a method for constructing laminated glass on an existing window frame, and in particular, a method for constructing laminated glass suitable for construction of laminated glass using netted glass defined for the purpose of preventing the spread of fire in fireproof areas and semi-fireproof areas. And a window structure with laminated glass.
[0002]
[Prior art]
As shown in FIG. 3, the laminated glass 50 is obtained by sandwiching an intermediate film 53 between two or more plate glasses 51 and 52 and bonding them all over (for example, see Patent Document 1 and Non-Patent Document 1). Such a laminated glass 50 is used for crime prevention purposes, disaster prevention purposes, and the like, and even if it is broken by the action of external force, most of the fragments are held by the intermediate film 53 and are not scattered.
[0003]
Since the general laminated glass 50 for crime prevention has a total glass thickness of about 7.5 mm (about 3 mm thick plate glasses 51 and 52 and about 1.5 mm thick intermediate film 53), a general 9 mm wide glass is used. It can be applied to an existing window frame (aluminum sash 10) provided with the fitting groove 11. The construction is performed by placing the setting block 12 in the glass fitting groove 11, fitting the laminated glass 50, and sealing with the sealant 13.
[0004]
However, as shown in FIG. 4, when the laminated glass 55 using the netted glass 54 (about 6.8 mm thick) defined for the purpose of preventing the spread of fire in the fire prevention area or the semi-fire prevention area is applied to the existing aluminum sash 10. Since the total glass thickness (about 11.3 mm) exceeds the width 9 mm of the general glass fitting groove 11, it cannot be applied as it is. Therefore, conventionally, in this case, as shown in FIG. 4, a laminated glass 55 is constructed using an aluminum attachment 56 and a PVC glazing channel or beats 57 and 58.

[Problems to be solved by the invention]
When such an attachment 56 and a PVC glazing channel or beat 57 are used, the laminated glass 55 and the attachment 56 can be joined only by the glazing channel or beat 57 wound around the laminated glass 55 being fitted into the attachment 56. Yes, and this attachment 56 only fits into a glazing channel or beat 58 bonded to the aluminum sash 10.
[0007]
For this reason, the attachment 56 is easily detached when an external force is applied to the laminated glass 55, and there is a problem that the laminated glass 55 is easily removed together with the attachment 56 by a technique such as prying to prevent crime. Moreover, in the structure using such an attachment 56, since the laminated glass 55 itself is not inserted in the aluminum sash 10, the strength advantage of the meshed glass 54 cannot be fully utilized.
[0008]
Furthermore, when the attachment 56 is used, the attachment 56 may protrude from the frame of the aluminum sash 10, so that in the case of a sliding window, the problem that the attachment 56 cannot be opened due to the thickness of the attachment 56, or a screen door is installed. The problem that it becomes impossible to occur.
[0009]
Therefore, in the present invention, when constructing a laminated glass whose total thickness exceeds the glass fitting groove in an existing window frame, it is possible to match this window frame without using an attachment or processing an existing window frame. It aims at providing the construction method of the laminated glass which can construct glass, and the window structure which constructed the laminated glass.
[0010]
[Means for Solving the Problems]
The laminated glass construction method of the present invention is a laminated glass construction method in which a laminated glass having an intermediate film sandwiched between two or more sheet glasses is applied to an existing window frame having a glass fitting groove of a predetermined width. And forming at least one sheet glass of the laminated glass smaller than the opening of the window frame, and fitting the remaining portion of the plate glass excluding the sheet glass into the glass fitting groove of the window frame, and aligning with the glass fitting groove. The gap with glass is sealed with a sealant.
[0011]
According to this construction method, even if the laminated glass is thicker than the glass fitting groove of the existing window frame, at least one plate glass excluding the plate glass fitted into the glass fitting groove among the laminated glasses is opened in the window frame. By forming it smaller than the part, it can be installed by fitting the remaining plate glass part excluding this plate glass in the glass fitting groove of the window frame and sealing the gap between this glass fitting groove and the laminated glass with a sealing agent Become.
[0012]
Here, when the glass fitted in the glass fitting groove is meshed glass, the joint between the window frame and the laminated glass can be strengthened with the strength of the meshed glass.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a front view of a window in which a laminated glass according to an embodiment of the present invention is constructed, and FIG. 2 is a cross-sectional view taken along line AA of FIG.
[0014]
As shown in FIG. 1 and FIG. 2, the laminated glass 1 in the embodiment of the present invention includes a meshed glass 2 having a thickness of about 6.8 mm as one sheet glass and a float having a thickness of about 3 mm as one sheet glass. A polyvinyl butyral (Poly Vinyl Butyral = PVB) film 4 having a thickness of about 1.5 mm as an intermediate film is sandwiched between the glass 3 and adhered to the entire surface, and the total thickness is about 11.3 mm.
[0015]
Hereinafter, a method of applying this laminated glass 1 to an aluminum sash 10 as an existing window frame provided with a glass fitting groove 11 having a predetermined width (general width 9 mm) will be described.
[0016]
First, the float glass 3 out of the two plate glasses constituting the laminated glass 1 is processed to be smaller than the opening 10 a of the aluminum sash 10. In the example of FIG. 2, the PVB film 4 is also smaller than the opening 10 a of the aluminum sash 10 like the float glass 3 and is processed to the same size as the float glass 3. If it is possible to fit into the glass fitting groove 11 of the aluminum sash 10, there is no need to process it.
[0017]
Then, the outer edge portion of the meshed glass 2 of the laminated glass 1 is fitted into the glass fitting groove 11 of the aluminum sash 10 and sealed with a sealant 13 as a sealing agent. At this time, if necessary, the setting block 12 is used to align the laminated glass 1.
[0018]
Thus, according to the construction method in this embodiment, even if it is the laminated glass 1 whose width | variety is thicker than the glass fitting groove | channel 11 of the existing aluminum sash 10, the net insertion fitted in the glass fitting groove | channel 11 among the laminated glasses 1 is carried out. The float glass 3 excluding the glass 2 is formed smaller than the opening 10a of the aluminum sash 10, and the outer edge portion of the remaining netted glass 2 excluding the float glass 3 is fitted into the glass fitting groove 11 of the aluminum sash 10, The gap between the glass fitting groove 11 and the laminated glass 1 can be sealed with a sealant 13 for construction.
[0019]
That is, according to the construction method in the present embodiment, it is possible to construct the existing aluminum sash 10 without any processing. In general, a metal window frame such as the aluminum sash 10 is manufactured by combining shapes formed by extrusion or the like, so that it is difficult to process the glass fitting groove 11. Therefore, when replacing with a laminated glass having a thickness that cannot be fitted in the glass fitting groove 11 of a metal window frame such as the existing aluminum sash 10, it has been necessary to exchange the aluminum sash 10 together. However, in the construction method in this embodiment, the laminated glass 1 thicker than the glass fitting groove 11 can be easily constructed without replacing the aluminum sash 10 and without processing the glass fitting groove 11. Thereby, it becomes possible to replace the glass fitted in the existing aluminum sash 10 with a laminated glass at a lower cost than before.
[0020]
Moreover, in the window structure constructed in this way, the laminated glass 1 itself is fitted in the glass fitting groove 11 of the aluminum sash 10 at the outer edge portion of the mesh-filled glass 2 without using the attachment 56, so that the aluminum A window structure that takes advantage of the strength of the meshed glass 2 at the joint between the sash 10 and the laminated glass 1 can be obtained.
[0021]
In the present embodiment, the laminated glass 1 has been described as an example in which the netted glass 2 and the float glass 3 are entirely bonded via the PVB film 4, but other plate glass is interposed via the other intermediate film. It can also be applied to those that are bonded together. In short, the present invention can be applied to all cases in which laminated glass having a total thickness exceeding the glass fitting groove is applied to an existing window frame.
[0022]
【The invention's effect】
According to the present invention, the following effects can be obtained.
[0023]
(1) At least one glass of laminated glass is formed to be smaller than the window frame, and the remaining glass excluding this glass is fitted into the glass fitting groove of the window frame, and the gap between the glass fitting groove and the laminated glass is sealed. By sealing by, it becomes possible to construct the laminated glass whose total thickness exceeds the glass fitting groove on the existing window frame without using an attachment and without processing any existing window frame. Moreover, since it becomes possible to install the laminated glass that exceeds the glass fitting groove without the total thickness exceeding the window frame, there is no problem in the conventional installation to the sliding window or the screen door.
[0024]
(2) Since the meshed glass is fitted into the glass fitting groove, the joint between the window frame and the laminated glass is reinforced with the strength of the meshed glass, so the mesh is inserted at the joint between the window frame and the laminated glass. A window structure that takes advantage of the strength of glass can be obtained.
