Description

DETAILED DESCRIPTION OF THE INVENTION <Field of Use> The present invention relates to a plastic laminated glass sheet molded article, more specifically, a corner portion where glass sheets are butted against each other, such as building materials and store equipment, particularly simple and reliable airtight or water. The present invention relates to a plastic laminated glass sheet molded product having joints at tight corners.

<Prior Art> Conventionally, to manufacture a corner in which glass plates are butted against each other, (1) a method of fitting the corner into a sash, (2) a method of bonding the corner with an adhesive such as a silicone resin, (3) A method of connecting only the ends of the corners with a connecting tool is known. However, in the method (1), a complicated sash is required and a labor such as sealing is required. In the method (2), there is a limit in strength and uncertainties in making the adhesive airtight or watertight. The method (3) does not become airtight or watertight.

<Object of the Invention> An object of the present invention is to provide a plastic laminated glass sheet molded product having a simple and reliable joint of the airtight or watertight corner portion.

The object of the present invention is achieved by the following constitutions.

<Structure of the Invention> The present invention is a plastic laminated glass plate in which a plastic sheet is adhered to one side or both sides of a glass plate, or a plastic sheet layer of a plastic laminated glass plate in which glass plates are adhered to both sides of a plastic sheet, leaving one sheet. The present invention relates to a plastic laminated glass sheet molded product obtained by cutting the layer (3) and sealing the remaining plastic sheet layer as a flexible joint to seal the corner portion.

The present invention will be described below with reference to the drawings. FIG. 1 is a sectional view of a joint of a plastic laminated glass plate in which a plastic sheet is adhered to one side of a glass plate, 1 is a plastic sheet, 2 is a glass plate, 3 is a gap between bent corners, and 4 is a glass plate. This is the corner edge. Only the glass sheet was cut at a predetermined position of the plastic laminated glass plate in which the plastic sheet 1 was adhered to one surface of the glass plate 2 with an adhesive (not shown), and the plastic sheet 1 was bent according to the cutting position. The joint part is shown.

FIG. 2 is a cross-sectional view of a joint of a plastic laminated glass plate in which plastic sheets are adhered to both sides of the glass plate, and one layer of the plastic sheet 1 is left at a predetermined position of the plastic laminated glass plate and another plastic sheet The joint part which cut | disconnected the glass plate and bent the plastic sheet 1 according to the cutting position is shown.

FIG. 3 is a sectional view of a joint of a plastic laminated glass plate in which glass plates are adhered to both sides of a plastic sheet, and two glass plates are cut at a predetermined position of the plastic laminated glass plate, leaving the plastic sheet 1. , One of the glass plates is further removed by 180 ° -θ depending on the bending angle θ, and the plastic sheet 1 is bent according to the cutting position.

FIG. 4 shows an example of manufacturing a case using the joint portion of the present invention. A glass sheet is cut at a dotted line portion of FIG. A predetermined case is easily manufactured by bending and adhering a plastic sheet as shown in FIG.

Any means such as diamond tip type glass cutting, roller tip type glass cutting, grinder type glass cutting, etc. is adopted for cutting the glass plate. When cutting a glass sheet, care should be taken not to damage the plastic sheet to be left behind, especially when using a grinder type glass cutting.

FIGS. 5 (A) to 5 (D) are for reinforcing the corners of the joint portion of the plastic laminated glass plate in which a plastic sheet is adhered to one surface of the glass plate shown in FIG. 1, for protecting the glass edge 4 and for aesthetic appearance. FIG. 5 (A) shows a sealing process, FIG. 5 (A) shows a state in which the gap 3 at the corner is filled with a sealing agent, and FIG. 5 (B) shows a round bar 5a in the gap 3 at the corner. Fig. 5 (C) shows a state in which a wedge-shaped rod 5b having a cross section corresponding to the bending angle is attached to the gap 3 at the corner with a sealing agent or the like, and Fig. 5 (D). Shows the state where the edge cover 5c is attached to the corner.

The rod-shaped body and the edge cover used here are made of any material such as glass, metal and plastic.
In particular, the rod-shaped body is preferably made of glass, and the edge cover is preferably made of stainless steel. Further, as the sealing agent, any one such as silicone-based, urethane-based, and thiocol-based is used.

The glass plate used in the present invention is generally a float glass plate and may be chemically strengthened. Although there is no particular limitation on the thickness, it is usually 2 to 10 mm for float glass plates and 0.1 to 2 mm for chemically strengthened ones.
Something is used.

As the plastic sheet, one having a thickness of about 10 to 2 mm is usually used, and one having a thickness of about 0.1 to 1 mm is preferable. The plastic sheet is preferably colorless or transparent because it is laminated on the glass plate, but there is no particular need for particular attention. Also, the type of plastic is not particularly limited, but polycarbonate, polyester, acrylic resin and the like are preferably used.

Adhesives used for laminating the plastic sheet to the glass plate are solvent type, thermoplastic type, UV type.
Any type such as a curing type may be used, and it is not particularly limited as long as it adheres glass and plastic, but peel strength of about 0.1 to 5 kg / cm is preferable, and about 0.5 to 2 kg / cm is particularly preferable. . The thickness of the adhesive layer is usually 0.05 ~
It is about 2 mm, preferably about 0.1 to 0.5 mm.

<Effects of the Invention> In the present invention, since the plastic laminated glass plate in which the plastic sheet is entirely laminated on the glass plate with the adhesive is used, the joint portion can be formed extremely easily and inexpensively, Moreover, even if the glass is broken, the broken glass hardly scatters, and even if the glass scatters or falls off, the airtightness or watertightness can be maintained only by the plastic sheet.
Further, by reinforcing the bent corner with a sealing agent or a rod-like member, it is possible to more reliably make it airtight or watertight. It is useful for building materials, shop accessories such as showcases and sushi counter covers, and cases such as doll cases.

<Example> The present invention will be further described with reference to the following examples.

Example 1 A glass plate of a plastic laminated glass plate obtained by adhering a polycarbonate sheet having a thickness of 0.5 mm to a heat ray reflecting glass plate having a thickness of 6 mm for a corner of a sunroom is cut by roller chip type glass cutting, and the polycarbonate sheet is θ = 12
It was bent at 0 ° to make a joint for a plastic laminated glass plate. A 30 ° wedge-shaped glass rod was attached to the corner with a silicone sealant to reinforce it. As for the direction of the beam, when it was fitted into the beam of the aluminum sash, there was no aluminum girder at the corner, so there was no worry of raining and it had a neat appearance.

Example 2 A doll case as shown in FIG. 4 (B) (height 400 mm, width 3
00mm, depth 300mm) was created. A plastic laminated glass plate (1100 mm x 1100 mm) in which a 0.5 mm thick polycarbonate sheet is adhered to a 3 mm thick glass plate is cut out according to the development view of Fig. 4 (A), and the dotted line part is a glass plate cut with a roller. Cut only, bend the polycarbonate sheet of this cut part as a joint, 3m at the corner
A mφ glass rod was attached with a silicone sealing agent to reinforce it, and a glass rod was attached to the other corners with a silicone sealing agent, and the end was reinforced with a metal plate stopper. The obtained doll case had no surrounding frame and had a neat appearance.
