The number of steps is as large as 105, the steps are complicated, and the work is troublesome. For this reason, it is difficult to increase the productivity, which causes a cost increase. In addition, since the intermediate layer 105 is required for press-bonding the netted glass plate 103 and the transparent glass plate 104, it causes a cost increase.

ップの要因となる。Further, if the thickness t12 of the transparent glass plate 104 is reduced to less than 2.0 mm, for example, by pressing the transparent glass plate 104 under high pressure, the transparent glass plate 104 may be damaged. Therefore, the thickness t of the transparent glass plate 104
12 needs to be set to 2.0 mm or more, which causes an increase in cost. Further, when the plate thickness t12 of the transparent plate glass 104 is set to 2.0 mm or more, the plate thickness t14 (1.6 mm) of the opening / closing door 101 becomes larger. For this reason, in order to make the surface 104a of the transparent plate glass 104 flush with the inner surface 101b of the door 101, a spacer 106 is required as shown in FIG.

る。[0010] Furthermore, in order to press the netted glass sheet 103 and the transparent glass sheet 104 under pressure, it is necessary to provide a heating equipment for heating to 120 to 150 ° C and a pressure equipment for applying pressure to 980 to 1470 KPa. For this reason, equipment costs increase. When the transparent glass sheet 104 is pressed, the transparent glass sheet 104 is shifted from the meshed glass sheet 103,
There is a possibility that defective products may be produced. Defective products are discarded, which causes an increase in the cost of the sight glass 102.

ラスの製造工程を簡略化することができる。[0013] Since the sheet glass and the transparent sheet glass are bonded together with a light-curing adhesive, an intermediate film (polyvinyl butyral) required for conventional laminated glass is not required. For this reason, the cost of the laminated glass can be reduced. Further, by using the photocurable adhesive, it is not necessary to apply high temperature and high pressure to the transparent glass sheet as in the case where the intermediate film is used. Therefore, the thickness of the transparent glass sheet can be reduced, and the cost of the laminated glass can be reduced. Furthermore, after bonding the netted sheet glass and the transparent sheet glass with a light-curing adhesive, the light-setting adhesive can be used to bond the sheet glass and the transparent sheet glass with sufficient adhesive strength. it can. For this reason, the manufacturing process of the laminated glass can be simplified.

下げることができる。The thickness of the transparent glass sheet can be set to be substantially the same as the thickness of the door of the elevator. For this reason, the transparent plate glass can be flush with the opening / closing door only by applying the meshed plate glass to the opening / closing door. Therefore, since there is no need to arrange a spacer between the meshed sheet glass and the opening / closing door to adjust the amount of the transparent sheet glass to be fitted, the work of attaching the laminated glass can be simplified. As a result, the cost of the laminated glass and the cost of attaching the laminated glass can be reduced.

る。According to a third aspect of the present invention, the meshed plate glass is placed horizontally, and a liquid photocurable adhesive is placed at the center of the glass.
Next, a transparent glass sheet is placed, the light curable adhesive is spread thinly by the weight of the transparent glass sheet, and the light curable adhesive is cured by irradiating light from below or above.

配もない。By spreading the photocurable adhesive thinly by the weight of the transparent glass sheet, it is not necessary to compress the intermediate film while heating it like a conventional laminated glass, and to bond the transparent glass sheet to the netted glass sheet. Therefore, equipment costs can be reduced by removing the heating device and the pressurizing device. Further, since there is no need to press the transparent plate glass, there is no fear that the transparent plate glass will be displaced from the meshed plate glass when the transparent plate glass is bonded.

The first half of ST11 in FIG. 3 will be described in detail in (c).
3A, the netted glass 21 is placed horizontally on a mounting table 40, a jig 42 is placed on the netted glass 21, and a liquid ultraviolet curable adhesive 26 is applied to the center of the netted glass 21 by a supply cylinder unit 44. A predetermined amount is dropped. In (b), the transparent plate glass 24 is placed on a liquid ultraviolet curable adhesive 26 as indicated by an arrow.

もない。In (c), the liquid ultraviolet curable adhesive 26 is spread thinly as indicated by the arrow by the weight of the transparent plate glass 24. By using the ultraviolet curing adhesive 26,
There is no need to crimp the transparent plate glass 24. For this reason, the thickness t2 of the transparent plate glass 24 can be set as thin as 2.0 mm or less (for example, 1.6 mm), so that the cost of the laminated glass 20 shown in FIG. 2 can be reduced. Also, since no heating device or pressurizing device is required,
Equipment costs can be reduced. Further, since the transparent plate glass 24 does not have to be pressed, there is no fear that the transparent plate glass 24 is shifted from the meshed plate glass 21 when the transparent plate glass 24 is bonded.

チポアズ（ｃP）を用いた。Here, the viscosity of the liquid ultraviolet curable adhesive 26 will be described. The viscosity refers to a resistance generated inside a flowing object, and is represented by viscosity = τ / (dv / dy). Here, τ is a shear stress (1) that acts due to viscosity on a plane parallel to the flow due to a flow at a point in the laminar flow.
kgf / m 2 ≒ 98 KPa), and (dv / dy) is
A velocity gradient (1 / s) in a direction perpendicular to the flow. The unit of the viscosity is Pascal · second (Pa · s) or poise (P), but the ultraviolet curable adhesive 26 has a low viscosity, so centipoise (cP) is used.

着剤２６を薄く広げることができるようにした。The liquid ultraviolet curable adhesive 26 is an adhesive whose viscosity is set to 10 to 100 cP. Viscosity is 10
When the pressure is less than cP, the ultraviolet-curable adhesive 26 is thinly spread and flows out only by dropping the liquid ultraviolet-curable adhesive 26 at the center of the netted plate glass 21. Therefore,
By setting the viscosity to 10 cP or more, it was made to remain at the center of the sheet glass 26 with mesh. The viscosity is 100 cP
Is exceeded, the UV curable adhesive 26 cannot be spread thinly on the liquid UV curable adhesive 26 by the weight of the transparent plate glass 24. Therefore, by setting the viscosity to 100 cP or less, the ultraviolet curable adhesive 26 can be spread thinly by the weight of the transparent plate glass 24.

The vertical axis indicates the adhesive strength of the ultraviolet curable adhesive, and the horizontal axis indicates the curing time. The adhesive strength is represented by a tensile shear strength, a compressive shear strength, a peel strength, and the like. Here, the adhesive strength is represented by a compressive shear strength.

According to the first aspect of the present invention, the sheet glass with the mesh and the transparent sheet glass are bonded with the photocurable adhesive, so that the intermediate film (polyvinyl butyral) required for the conventional laminated glass can be omitted. For this reason, the cost of the laminated glass can be reduced. Further, by using the photocurable adhesive, it is not necessary to apply high temperature and high pressure to the transparent glass sheet as in the case where the intermediate film is used. Therefore, the thickness of the transparent glass sheet can be reduced, and the cost of the laminated glass can be reduced.

For this reason, the transparent plate glass can be flush with the opening / closing door only by applying the meshed plate glass to the opening / closing door. Therefore, since there is no need to arrange a spacer between the meshed sheet glass and the opening / closing door to adjust the amount of the transparent sheet glass to be fitted, the work of attaching the laminated glass can be simplified. As a result, the cost of the laminated glass and the cost of attaching the laminated glass can be reduced.

For this reason, like conventional laminated glass,
Since no heating equipment or compression equipment is required, equipment costs can be reduced. As a result, the cost of the laminated glass can be reduced. Further, since the transparent glass sheet does not need to be pressed, there is no fear that the transparent glass sheet will be displaced from the meshed glass sheet when bonding the transparent glass sheets.
