Description

  The present invention relates to a laminated plate-shaped member, a method for manufacturing the laminated plate-shaped member, and a unit plate-shaped member, and more particularly, a laminated glass that is a laminated plate-shaped member, and a laminated glass for a facade constructed as a wall surface of a building. The present invention relates to glass, a method for producing the laminated glass, and a unit plate member in which the laminated glass and the support member are unitized.

  The example which comprised the glass plate currently widely used as a plate-shaped member as a laminated glass is demonstrated. Laminated glass is generally a glass for facades that is constructed by thermocompression bonding of two glass plates through PVB (polyvinyl vinyl butyral) sheet or the like as an intermediate adhesive layer. Widely used as windshield glass for vehicles such as automobiles.

  Laminated glass configured for wall surfaces is usually attached to and supported by a metal sash frame (supporting member), but the sash frame protrudes outward from the surface of the laminated glass, so the entire building As a result, the design was inferior and the appearance was poor. Therefore, recently, a support structure for laminated glass in which the sash frame does not protrude from the surface of the laminated glass has been proposed.

  As an example, the laminated glass supporting structure disclosed in Patent Document 1 has a beveling process on the side of the intermediate film of the fore end of the indoor glass, and a locking portion of the supporting member is provided in the groove formed by the beveling process. The laminated glass is supported by being locked without protruding outward from the surface of the laminated glass. In addition, this laminated glass is manufactured by thermocompression bonding of indoor side glass that has been slope-cut in advance and outdoor glass that has not been slope-cut.

On the other hand, in the laminated glass disclosed in Patent Document 2, the surface side glass is made smaller in size than the back side glass, and the edge of the surface side glass is retreated from the edge of the back side glass. A step portion is formed at the peripheral portion on the surface side of the glass. And this support structure of laminated glass supports the laminated glass by making the latching | locking part of a supporting member latch on the step part of a laminated glass, without protruding outward from the surface of a laminated glass.

  By the way, in the laminated glass which laminated | stacked only the indoor side glass to which a supporting member is latched like patent document 1, and the outdoor side glass which has not carried out the chamfering process beforehand, and its support structure In order to lock the beveled portion with the locking portion of the support member, the thickness of the indoor side glass to be beveled needs to be 8 mm or more from the viewpoint of the strength of the beveled portion and the problem of the support member being stored. Is done. On the other hand, depending on the application, storage, and wind pressure conditions, it is known that even a laminated glass using non-tempered glass having a thickness of 6 mm or less can obtain sufficient strength for facade use.

  However, in the laminated glass supporting structure of Patent Document 1, a thin non-tempered glass having a thickness of 6 mm or less cannot be used due to the above-described problem, and a glass plate having an unnecessarily thick plate must be used.

  In addition, in the laminated glass support structure described in Patent Documents 1 and 2, since the outdoor glass is not supported by the support member and is supported by adhesion only to the intermediate film, moisture or the like enters the intermediate film. When the adhesive strength of the interlayer film is reduced, there is a problem that the risk of the outdoor glass dropping off from the indoor glass increases.

  Furthermore, since the laminated glass of Patent Document 1 is sloped on the side in contact with the intermediate film, the laminated glass is produced using a single plate glass that has been sloped beforehand. With the current manufacturing method, it has been difficult to accurately position the glass plate that has been chamfered. That is, generally, the alignment of the two glass plates constituting the laminated glass is often a manual operation, and two pieces having different dimensions such as edge processing as in the cited document 1 and cited document 2 are used. In order to align the glass plate with high accuracy, high skill was required. In addition, if the glass plate is pre-sloped, the sides are weak against impacts, etc., and the sides are damaged only by contacting the peripheral devices during alignment. There was also a problem.

  On the other hand, a flat surface can be realized by applying the DPG construction method to laminated glass using tempered glass. However, since tempered glass is used, the warpage of the glass accompanying heat treatment tends to be larger than that of non-tempered glass, and it is also disadvantageous in terms of foaming, white turbidity, peeling, etc. of the interlayer film. It has been. Moreover, the need to use non-tempered glass as a glass plate of laminated glass is increasing for cost reduction.

  By the way, in the case of a highly decorative laminated glass (hereinafter referred to as “decorated laminated glass”) in which an organic material, an inorganic material, or a metal material is interposed inside the intermediate adhesive layer of the laminated glass, the influence of ultraviolet rays and heat In addition, due to the intrusion of moisture from the glass edge, the intermediate adhesive layer often becomes cloudy or delamination occurs near the glass edge, so care must be taken when used for exterior applications. there were. In short, in the case of decorative laminated glass, a high waterproof property is required for the intermediate adhesive layer exposed at the edge.

  This invention is made | formed in view of such a situation, and it aims at providing the laminated plate-shaped member which can be supported safely. Another object of the present invention is to provide a method for manufacturing a laminated plate member with beveling that is easy to manufacture. It is another object of the present invention to provide a unit plate-like member that can safely support a laminated plate-like member by protecting and concealing an intermediate adhesive layer exposed at the edge.

In order to achieve the above object, the present invention constructs a laminated plate-like member formed by bonding two or more plate-like members arranged opposite to each other via an intermediate adhesive layer, and the laminated plate-like member. A unit plate-like member comprising a support member locked to the laminated plate-like member to be supported by an object, from the first plate-like member disposed on the surface side of the laminated plate-like member A beveled portion is continuously formed at the end of the mating plate-like member over the second plate-like member adjacent to the first plate-like member, and the beveled portion is formed of the mating plate-like member. Provided is a unit plate-like member which is constituted by beveling an end portion, and wherein the support member is locked to the beveled portion .

According to the laminated plate- like member of the unit plate-like member of the present invention, even if the plate-like member is a thin plate, the beveled portion is removed from the first plate-like member disposed on the surface side of the laminated plate-like member, Since the second plate-shaped member adjacent to the first plate-shaped member is continuously formed, a continuous beveling portion is formed from the first plate-shaped member to the second plate-shaped member. Necessary dimensions can be secured. Therefore, even in the case of a laminated plate member using a relatively thin plate member, it can be safely supported.

According to the method for manufacturing a unit plate member of the unit plate member , first, two or more plate members having the same plane size that are not beveled are arranged opposite to each other, and the intermediate adhesive layer is interposed therebetween. A laminated plate-like member having no beveled surface is produced by superimposing and bonding them together by thermocompression bonding. The positioning of the plate-shaped member at this time is easy because the plate-shaped member is not sloped. In addition, the plate-like member is not pre-sloped and the side portion has no cross-sectional defect, so even if the side portion contacts peripheral equipment during alignment, the side portion is damaged. There is little worry. Next, the laminated plate member is subjected to beveling processing exceeding the thickness of one plate member constituting the laminated plate member.

After thus manufactured combined plate-shaped member which is not obliquely chamfered by performing slope preparative process this mating plate-like member, it becomes easy alignment between the plate-shaped member, thus facilitating the production A method for producing a laminated plate member with a beveled surface can be provided . Although not the inclination angle of the swash chamfering is particularly limited, preferably about 45 degrees.

Prior Symbol plate member a transparent plate, it is preferable that the the intermediate adhesive layer is an intermediate layer of colored is interposed.

That is , a decorative laminated plate member having high design can be provided by using a transparent plate as the plate member and interposing a colored intermediate film in the intermediate adhesive layer. Here, the colored intermediate film means a material having adhesive properties such as poly-vinyl-butyral (PVB) or ethylene-vinyl-acetate (EVA). As another form, a decorative film is used as a pair of intermediate films. What is sandwiched between films is also included in the colored intermediate film. In addition, as a decorative film, a colored decorative film such as black, white, or blue, or a decorative film on which various designs and patterns are directly printed can be used. Thereby, the designability of a facade improves.

Prior Symbol plate member a transparent plate, it is preferable that all or a member other than a portion in the middle layer of the intermediate adhesive layer in the plane is interposed.

In other words , the plate- like member is a transparent plate, and the intermediate adhesive layer is made of, for example, an organic material such as Japanese paper, quilt (woven fabric), or leaves, a punching metal, a wire mesh, a metal blind, a glass bead or the like, or a metal material. By interposing, it is possible to provide decorative laminated plate members having a wide variety of appearance designs. For example, by forming an intermediate adhesive layer in which glass beads are sandwiched and held between two intermediate films, a deep laminated plate-like member having a high design property can be provided. Moreover, the surface of the plate-like member is subjected to surface treatment such as matte treatment, whereby a laminated plate-like member rich in changes can be provided.

According to the present invention, the plate-like member is non-tempered glass, the thickness of the first plate-like member is 6 mm or less, and the beveled portion is a C chamfer of 8 mm or more in the thickness direction. It is preferable that processing has been performed.
According to the present invention, the locking portion of the support member that faces the beveled portion is locked to the beveled portion via silicone rubber, and the backup portion of the support member is the fixing plate-like member. It is preferable that the second plate-like member is bonded and fixed to the fore edge side of the back surface of the second plate member via the silicone rubber and a sealing material.

  According to the present invention, by making the plate-like member non-tempered glass, it is possible to perform bevel cutting after the laminated glass is manufactured. In addition, as described above, it is known that even a laminated glass using a non-tempered glass having a thickness of 6 mm or less can obtain a sufficient strength for a facade depending on use, storage, and wind pressure conditions. Therefore, a laminated glass using non-tempered glass having a thickness of 6 mm or less is used as the first plate-like member, and a C chamfering process of 8 mm or more is performed in the thickness direction. Here, the C chamfering means slope chamfering that is removed from the ridge line portion where the surface of the laminated plate-like member and the fore edge face intersect each other in the surface direction and the fore edge direction. That is, the surfaces created by the chamfering process are inclined at an angle of about 45 degrees with respect to the surface of the laminated plate member and the facet. Therefore, when non-tempered glass having a thickness of 6 mm or less is used for the first plate-like member and C-chamfering of 8 mm or more is performed in the thickness direction, the non-tempered glass (first plate-like member located outside) ) To beveled continuously over the non-tempered glass (second plate member) adjacent to the non-tempered glass. Note that the basis for setting the C chamfering amount to 8 mm or more is the minimum that can securely support the laminated glass with the support member when the locking portion of the support member is locked to the slope chamfered portion via the cushioning material. It comes from the dimensions of

  In addition, it is preferable on manufacture that the supporting member is an extrusion mold material made of an aluminum alloy. In this case, it is preferable that the beveled portion is supported by the supporting member via a cushioning material. Moreover, it is preferable that the supporting member is bonded and fixed with an adhesive in the vicinity of the small edge part on the back side of the indoor side glass (second plate-like member). Furthermore, it is preferable that hinge bolts are attached to the support member at a plurality of locations, and a unit plate member (unit glass) is attached to the building via these hinge bolts.

  According to the unit plate member of the present invention, the support member is locked to the beveled portion of the laminated plate member. Since the beveled portion is formed from the first plate member disposed on the surface side of the laminated plate member to the second plate member adjacent to the first plate member, the surface side When the first plate-like member arranged on the outside is the outside of the facade, the support member holds the first plate-like member via the beveled portion. Therefore, even if the adhesive force of the intermediate adhesive layer is reduced, there is little risk that the first plate-like member will drop off. In addition, the support member protects and conceals the intermediate adhesive layer exposed to the edge by holding the beveled portion formed continuously from the first plate-like member to the second plate-like member. It is possible to hide foaming and peeling at the end of the intermediate adhesive layer. In particular, decorative laminated plate-like members (decorated laminated glass) interposing members such as organic materials, inorganic materials, or metal materials other than the interlayer film are affected by ultraviolet rays, heat, and moisture intrusion from the edge. Due to the influence, the intermediate adhesive layer often becomes cloudy or delamination occurs in the vicinity of the forehead, and attention is required when used for exterior applications. In the unlikely event that the inclined member formed continuously from the plate member (outdoor glass) to the second plate member (inside glass) is held by the support member, the adhesive force of the intermediate adhesive layer Even if it falls, there is little risk that the 1st plate-shaped member (outdoor glass) will fall off. Further, the laminated plate-like member can be held safely and on a flat surface having high design properties without depending on the adhesiveness of the intermediate film. In addition, in order to perform beveling processing after the alignment processing, when the plate-like member is a glass plate, non-tempered glass is assumed. Even if the non-tempered glass is broken, the broken glass piece is bonded to the intermediate adhesive layer, so that the glass piece can be prevented from scattering and function as safety glass.

  As described above, according to the present invention, a laminated plate member that can be safely supported can be provided. Moreover, according to this invention, the manufacturing method of the laminated plate-like member with the beveling process easy to manufacture can be provided. Furthermore, according to the present invention, it is possible to provide a unit plate-like member that can safely support the laminated plate-like member by protecting and concealing the intermediate adhesive layer exposed in the forehead.

  DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of a laminated plate member, a method for producing a laminated plate member, and a unit plate member according to the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is a cross-sectional view of a main part of a laminated glass 10 of the first embodiment and a unit glass (unit plate member) 14 in which the laminated glass 10 and a sash frame (supporting member) 12 are integrated. The perspective view shown is shown. FIG. 2 is a horizontal sectional view of FIG.

  As shown in these drawings, the laminated glass 10 is configured such that an outdoor side glass (first plate member) 18 and an indoor side glass (second plate member) 16 having the same plane dimensions are arranged to face each other. At the same time, they are laminated via the intermediate adhesive layer 20, and are formed by thermocompression bonding them together. In addition, non-tempered glass is applied to the outdoor side glass 18 and the indoor side glass 16 in order to perform beveling processing described later.

  As the intermediate adhesive layer 20, in addition to adhesive films such as polyvinyl vinyl butyral (PVB), ethylene vinyl acetate (EVA), and urethane, thermoplastic resin adhesive, elastomer adhesive, thermosetting resin adhesive However, it is preferable to use an intermediate film made of ethylene / vinyl / acetate which is excellent in adhesion performance and water resistance.

  Next, the manufacturing method of the laminated glass 10 is demonstrated.

  First, the outdoor side glass 18 and the indoor side glass 16 which are non-strengthened glass that has not been slope-cut are overlapped via the intermediate adhesive layer 20 and bonded together by thermocompression bonding. Not produce laminated glass. The alignment between the outdoor side glass 18 and the indoor side glass 16 at this time is easy because the outdoor side glass 18 and the indoor side glass 16 are not sloped. Further, the outdoor side glass 18 and the indoor side glass 16 are not subjected to beveling processing in advance, and the side portions thereof are free from cross-sectional defects. There is little worry that the side will be damaged. The “beveling process” referred to here is a characteristic of the present invention, such as a beveling part continuously applied from the first plate-like member to the second plate-like member. This shows a beveling process formed over a relatively large area with respect to the small facet, and does not include a beveling process applied to a minute area such as a so-called thread chamfering.

  Next, the laminated glass is continuously subjected to bevel cutting across the outdoor glass 18 constituting the laminated glass and the indoor glass 16 adjacent to the outdoor glass 18. That is, a laminated glass is set on a chamfering machine, and a side of the laminated glass is ground by a chamfering grindstone of the chamfering machine to perform a beveling process. Thereby, the beveling part 22 which reaches the indoor side glass 16 beyond the outdoor side glass 18 is formed in the side part of a laminated glass, and the laminated glass 10 of embodiment is manufactured.

  In the manufacturing method of the laminated glass 10 of such embodiment, first, the laminated glass which has not been beveled is produced, and thereafter, the laminated glass is subjected to the beveling process. Positioning with the glass 16 becomes simple, and therefore, the laminated glass 10 with a beveling process that is easy to manufacture can be provided. Further, even if the outdoor side glass 18 and the indoor side glass 16 are thin plates (for example, a thickness of 6 mm or less (nominal thickness: 4 mm, 5 mm, 6 mm)), the beveling processing exceeds the outdoor glass 18. Therefore, the laminated glass 10 can be ensured to have a required dimension of beveling (for example, C chamfering of 8 mm). The laminated glass 10 shown in FIGS. 1 and 2 is bonded to two glass plates having a nominal thickness of 6 mm via an intermediate adhesive layer and is subjected to 8 mm C chamfering in the thickness direction a. ing.

  Furthermore, according to the unit glass 14 of the embodiment, the sash frame 12 is attached so as to surround the side portion (small edge) where the beveled portion 22 of the laminated glass 10 is formed. Since the sash frame 12 is locked to the beveled portion 22, the sash frame 12 holds the laminated glass 10 including the outdoor side glass 18. Therefore, even if the adhesive force of the intermediate adhesive layer 20 is reduced, the risk of the outdoor glass 18 falling off is small.

  Here, the structure of the sash frame 12 will be described.

  The sash frame 12 is made of an aluminum alloy manufactured by extrusion molding, and the locking portion 12A, the backup portion 12B, and the rail portion 12C are integrally formed. These locking portions 12 </ b> A, backup portions 12 </ b> B, and rail portions 12 </ b> C are formed in a long shape along the side portion of the laminated glass 10.

  12 A of latching | locking parts are formed in the cross-sectional substantially triangular shape according to the shape of the beveling part 22 so that it may not protrude outside from the surface of the outdoor side glass 18, and it buffers to the beveling part 22 of the laminated glass 10 It is locked via a silicone rubber 24 that is a material. The backup portion 12B is formed in a flat plate shape along the edge surface of the side portion of the laminated glass 10, and the silicone rubber 24 and the sealing material 26 are provided on the edge side of the back surface of the indoor side glass 16 (laminated glass 10). It is bonded and fixed through. Furthermore, the rail portion 12 </ b> C is formed in a concave shape, and the tip fitting portion 32 of the rod-shaped support hardware 30 provided with the hinge bolt 28 is fitted. The position of the support metal 30 relative to the side portion of the sash frame 12 is obtained by fitting the tip fitting portion 32 of the support metal 30 to the rail portion 12C and sliding the tip fitting portion 32 in the longitudinal direction of the rail portion 12C. Is arbitrarily adjusted. After the position adjustment, the unit glass 14 is fixed to the housing via the support hardware 30 by fixing the base end portion 34 of the support hardware 30 to the housing side of the building. The above is the configuration of the sash frame 12.

  The sash frame 12 thus configured holds the beveled portion 22 continuously formed from the outdoor side glass 18 to the indoor side glass 16, thereby foaming and peeling off the end of the intermediate adhesive layer 20. Can be hidden. Moreover, the laminated glass 10 can be safely hold | maintained on a flat surface with high designability, without depending on the adhesiveness of the intermediate contact bonding layer 20.

  On the other hand, it is preferable that a colored intermediate film is interposed in the intermediate adhesive layer 20 of the laminated glass 10 of the embodiment.

  That is, a decorative laminated glass with high design can be provided by interposing a colored intermediate film in the intermediate adhesive layer 20. Here, the colored intermediate film means an adhesive material such as PVB or EVA, but as another form, a colored intermediate film includes a decorative film sandwiched between a pair of intermediate films. In addition, as a decorative film, a colored decorative film such as black, white, or blue, or a decorative film on which various designs and patterns are directly printed can be used. Thereby, the designability of a facade improves.

  In addition, the intermediate adhesive layer 20 of the laminated glass 10 according to the embodiment may be made of, for example, organic materials such as Japanese paper, quilt (woven fabric), and leaves, punched metal, wire mesh, metal blinds, inorganic materials such as glass beads, or metal It is preferable that a material is interposed.

  That is, by interposing a member other than the intermediate film, such as an organic material, an inorganic material, or a metal material, in the intermediate adhesive layer 20, decorative laminated glasses having a wide variety of appearance designs can be provided. For example, by using the intermediate adhesive layer 20 in which glass beads are sandwiched and held between two intermediate films, the laminated glass 10 having a deep design property can be provided. Moreover, the surface of the outdoor side glass 18 is also subjected to surface processing such as mat processing, whereby the laminated glass 10 rich in change can be provided.

  Furthermore, in the laminated glass 10 of the embodiment, the thickness of the outdoor glass 18 is 6 mm or less, and the beveled portion 22 is subjected to C chamfering processing of 8 mm or more in the thickness direction a. preferable.

  That is, according to the laminated glass 10 of embodiment, since the outdoor side glass 18 and the indoor side glass 16 are made into non-tempered glass, the beveling process after manufacturing a laminated glass is attained. Moreover, since it is known that sufficient strength can be obtained even with laminated glass using non-tempered glass (outdoor glass 18) having a thickness of 6 mm or less, as the first plate member, A laminated glass using an outdoor glass 18 having a thickness of 6 mm or less is used, and a C chamfering process of 8 mm or more is performed in the thickness direction a. Here, the C chamfering means slope chamfering that is removed from the ridge line portion where the surface of the laminated plate-like member and the fore edge face intersect each other in the surface direction and the fore edge direction. That is, the surfaces created by the chamfering process are inclined at an angle of about 45 degrees with respect to the surface of the laminated plate member and the facet. Therefore, when the laminated glass 10 is manufactured using the outdoor side glass 18 having a thickness of 6 mm or less, and C-chamfering processing of 8 mm or more is performed in the thickness direction a, the indoor side glass 16 is passed through the outdoor side glass 18. The reaching beveling process is continuously performed. The basis for setting the C chamfering amount to be 8 mm or more is that the laminated glass 10 can be reliably supported by the sash frame 12 when the locking portion 12A of the sash frame 12 is locked to the beveled portion 22. It comes from the dimensions of

  FIG. 3 shows a perspective view of the laminated glass 50 according to the second embodiment, and a cross-sectional view of the main part of the unit glass 54 in which the laminated glass 50 and the sash frame 52 are integrated. FIG. 4 is a horizontal sectional view of FIG. In the description of the laminated glass 50 and the unit glass 54, the same or similar members as those of the laminated glass 10 and the unit glass 14 shown in FIGS. To do.

  The laminated glass 50 shown in FIGS. 3 and 4 is manufactured by the same manufacturing method as the laminated glass 10. In other words, the non-tempered glass outdoor glass 18 and the indoor glass 16 that are not beveled are arranged opposite to each other, overlapped via the intermediate adhesive layer 20, and bonded together by thermocompression bonding. By doing so, a laminated glass without a bevel is manufactured. Next, the laminated glass is subjected to beveling processing exceeding the outdoor glass 18 constituting the laminated glass. Thereby, the beveled part 22 which reaches the indoor side glass 16 beyond the outdoor side glass 18 is continuously formed in the side part of the laminated glass, and the laminated glass 50 of embodiment is manufactured.

  Therefore, also in the manufacturing method of this laminated glass 50, first, the laminated glass which has not been beveled is produced, and thereafter, the laminated glass is subjected to beveling, so that the outdoor side glass 18 and the indoor side glass 16 are provided. Therefore, it is possible to provide the laminated glass 50 with the beveling process that is easy to manufacture. In addition, according to this laminated glass 50, the entire edge of the indoor side glass 16 is also beveled.

  Similarly to the sash frame 12, the sash frame 52 is made of an aluminum alloy manufactured by extrusion molding, and the locking portion 52A, the backup portion 52B, and the rail portion 52C are integrally formed. These locking portions 52 </ b> A, backup portions 52 </ b> B, and rail portions 52 </ b> C are also formed in a long shape along the side portion of the laminated glass 50.

  The locking portion 52 </ b> A is formed in a flat plate shape with a length that does not protrude outward from the surface of the outdoor glass 18, and is bonded and locked to the beveled portion 22 of the laminated glass 50 via the silicone rubber 24. The backup unit 52B and the rail unit 52C have the same configurations as the backup unit 12B and the rail unit 12C shown in FIGS.

  The sash frame 52 configured in this manner holds the beveled portion 22 formed continuously from the outdoor side glass 18 to the indoor side glass 16, thereby foaming and peeling off the end of the intermediate adhesive layer 20. Can be hidden. Further, the laminated glass 50 can be held safely and on a flat surface having high design properties without depending on the adhesiveness of the intermediate adhesive layer 20.

  Further, similarly, in the laminated glass 50, the thickness of the outdoor glass 18 is preferably 6 mm or less, and the beveled portion 22 is preferably C-chamfered by 8 mm or more in the thickness direction. Since the effect was demonstrated with the laminated glass 10 demonstrated previously, the description is abbreviate | omitted here. The laminated glass 50 shown in FIGS. 3 and 4 is formed by bonding two glass plates having a nominal thickness of 4 mm via an intermediate adhesive layer and performing a chamfering process of about 8 mm in the thickness direction. ing.

  In the embodiment shown in FIG. 1 to FIG. 4, inorganic glass is exemplified as the plate-like member, but the plate-like member may be an organic polycarbonate resin plate or an acrylic resin plate. Including those laminated by mixing. Moreover, when using a glass plate, various plate glasses, such as heat ray reflective glass, hard coat Low-E glass, ceramic printed glass, and meshed plate glass, are applicable besides normal float plate glass. Furthermore, the above-described embodiment can be applied to a laminated plate member formed by bonding three or more plate members through an intermediate adhesive layer.

  Furthermore, in the embodiment, the description has been given by limiting the size of the chamfered portion to C chamfering processing of 8 mm in the thickness direction, but the size is not limited to 8 mm. However, when the unit glass 14 to which the sash frame 12 is attached is used, it is not preferable to make the chamfer dimension too small because strength safety as the unit glass 14 is lowered.

[Examples and Comparative Examples]
As an example, two FL6s (nominal thickness 6 mm float glass plate) that are not beveled are placed facing each other and heated and pressed by an autoclave method through an intermediate adhesive layer. After the glass was manufactured, a C-chamfering process of 8 mm in the thickness direction was performed on the edge of the laminated glass (the edge side of the glass and the surface side had a chamfering amount of 8 mm on each side, and the inclination angle was 45 degrees). Thereafter, the sash frame was locked and fixed to the beveled portion. Thereby, it is possible to provide an easily manufactured unit glass having high design properties and wind pressure resistance.

  As a comparative example, a laminated glass using FL8 (float glass plate having a nominal thickness of 8 mm) subjected to beveling is illustrated. Before manufacturing the laminated glass, FL8 that has been chamfered (C chamfering) about 8 mm in the entire width in the thickness direction is used as the outdoor glass, and FL8 that has not been chamfered is used as the indoor glass. When the laminated glass is manufactured, the edge of the outdoor glass of the laminated glass has an acute angle. In the manufacturing method in which laminated glass is formed by thermocompression bonding of the outdoor glass that has been beveled and the indoor glass that has not been beveled through an intermediate adhesive layer, the acute angle of the outdoor glass Is easily damaged. Further, when the thickness of the glass plate is 8 mm or more, only the outdoor glass is sloped.

  As mentioned above, although embodiment thru | or Example of this invention has been explained in full detail using drawing, this invention is not limited to the said embodiment thru | or Example, In the range which does not deviate from the summary of this invention Various design changes and the like are possible.
