Description

The present invention relates to a glazing channel for a double-glazed glass used when mounting the double-glazed glass on a sash frame and, more particularly, to prevent the occurrence of internal dew condensation in the double-glazed glass. The present invention relates to a glazing channel for double-glazed glass capable of improving mounting workability and productivity, and a mounting method thereof.

  Conventionally, as shown in FIGS. 3 to 5, a window of a building has a rubber-like elasticity between a plurality of glass plates 2 a and 2 b in a sash frame 1 having a concave cross section constituting a window frame made of aluminum or the like. When the multilayer glass 5 in which the space layer 4 is formed is attached via the spacer 3 composed of the primary seal material 3a and the secondary seal material 3b composed of the body and the spacer member 3c, a sash frame is provided on the peripheral portion of the multilayer glass 5 A sealing frame 6 extruded and formed into an irregular cross section having a concave cross section called a glazing channel for the purpose of watertightness and airtightness of the gap between the glass 1 and the multilayer glass 5 is fitted and mounted. A method of fitting and mounting the multi-layer glass 5 mounted in advance on the bottom surface of the sash frame 1 with a setting block 7 interposed is performed (for example, see Patent Document 1).

  The sealing frame 6 (glazing channel) having a concave cross section as described above is provided with a plurality of drain holes 8 on the bottom surface by a soft / hard vinyl chloride resin (PVC) by an extrusion molding machine, and is extruded to an irregular cross section. Therefore, by fitting and attaching the multi-layer glass 5 to the periphery of the multi-layer glass 5 before the multi-layer glass 5 is attached to the sash frame 1, the water and airtightness with the outside is maintained and stress due to wind pressure is reduced. A function of preventing cracking due to external force is added to the multilayer glass 5.

  However, moisture such as rainwater that has entered from the gap X between the sealing frame 6 and the multi-layer glass 5 gives the secondary sealing material 3b (airtightness and watertightness between the two glass plates 2a and 2b). Which has been used for the purpose) causes a problem in long-term durability, such as causing condensation on the inner surfaces of the glass plates 2a and 2b of the multilayer glass 5.

  Further, in the step of fitting and attaching to the peripheral portion of the multilayer glass 5 of the sealing frame 6 (glazing channel), it is necessary to prepare a standard material corresponding to the total thickness of the multilayer glass 5. Therefore, it is difficult to manage the parts, and the cutting work of the standard material (adjusted to a certain length according to the size of the glass plate) and the fitting / mounting work itself are manual work that relies on manpower. In addition, there is a problem in terms of the environment because a large amount of soft and hard vinyl chloride resin cutting waste is generated during cutting.

Furthermore, in the normal manufacturing process of the multilayer glass 5, in order to protect the glass edge portion of the multilayer glass 5, a protective tape is applied after the secondary sealing material 3b is placed between the glass plates 2a, 2b as described above. There was a problem that it took a lot of time and labor.

  FIG. 1 shows a cross-sectional view of a sash assembly portion in which a multi-layer glass fitted with a glazing channel (seal frame) for multi-layer glass according to a first embodiment of the present invention is mounted on a sash frame. A sash frame 5 such as aluminum having a concave cross section serving as a window frame is formed from a primary sealing material 3a made of hot melt (adhesive), a thermoplastic resin material, or a reactive resin material between two glass plates 2a and 2b. The space layer 4 is formed through the spacer 3 composed of the spacer member 3c previously filled with or containing a desiccant with a secondary sealing material 3b and a material such as aluminum, thermoplastic resin, and thermoplastic elastomer. The multilayer glass is shown.

  The peripheral edge of the multi-layer glass 5 has a concave cross section called a glazing channel for the purpose of water-tightness and air-tightness in the gap between the multi-layer glass 5 and the sash frame 1 via an adhesive layer 10 made of hot melt. A sealing frame 6 made of a thermoplastic elastomer extruded into an irregular cross section is fitted and mounted.

  This frame 6 for sealing is formed by extrusion molding into an irregular cross section. Before the multi-layer glass 5 is mounted on the sash frame 1, it is fitted and mounted on the peripheral edge of the multi-layer glass 5, and the sash frame 1 is further fitted. The multi-layer glass 5 is fitted and mounted in a state in which the setting block 7 is interposed on the bottom surface portion. Further, it is preferable that the sealing frame 6 is continuously attached to the entire circumference of the peripheral edge portion of the multilayer glass 5 via the adhesive layer 10.

  The sealing frame 6 made of the thermoplastic elastomer is integrally bonded to the sealing frame mounting portion at the peripheral edge of the multilayer glass 5 via the adhesive layer 10, and the sealing frame 6 is It is integrally formed with a concave cross section. Examples of the hot melt used for the adhesive layer 10 include a hot melt mainly composed of butyl rubber, ethylene propylene rubber, styrene block copolymer, amorphous polyolefin, polyisobutylene, polyester, and the like, and mainly composed of polyurethane. The reaction type hot melt can be used, and preferably has adhesiveness and contains a silane compound.

  Further, as the adhesive layer 10, a one-component or two-component adhesive mainly composed of urethane resin, silicone resin, epoxy resin, acrylic resin or the like can be used, and preferably contains a silane compound. When the sealing frame 6 is extruded and simultaneously bonded to the glass plates 2a and 2b, a pre-apply type adhesive mainly composed of urethane resin and acrylic resin is advantageous, and preferably a polyester resin is used as a skeleton. The main component is urethane resin.

  FIG. 2 is a cross-sectional view similar to FIG. 1 in the second embodiment of the present invention. In the second embodiment, the sealing frame 6 is divided and molded at the center. In this embodiment, the divided sealing frames 6a and 6b are disposed on the bottom surface with a space S therebetween, and the hot melt is interposed between the two glass plates 2a and 2b as in the first embodiment. (Primary sealing material 3a made of (adhesive), secondary sealing material 3b made of a thermoplastic resin material or reactive resin material, and materials such as aluminum, thermoplastic resin, thermoplastic elastomer, etc. It is constructed by assembling to a multi-layer glass 5 in which a space layer 4 is formed via a spacer 3 composed of a contained spacer member 3c.

  That is, sealing frame bodies 6a and 6b that are divided through the adhesive layer 10 made of the same hot melt as described above are fitted and attached to the peripheral edge portion of the multilayer glass 5. Since other configurations and operations are the same as those in the first embodiment, the same reference numerals are given and description thereof is omitted.

  Next, a method of attaching the glazing channel (sealing frame) for double-glazed glass will be described.

  First, when the multi-layer glass 5 is mounted on the sash frame 1 via the sealing frame 6, the adhesive layer 10 made of hot melt is applied to the sealing frame mounting portion at the periphery of the multi-layer glass 5. The sealing frame 6 extruded into a certain shape from the extruder is integrally bonded simultaneously.

  Specifically, for example, a primary seal material 3a made of hot melt (adhesive) and a secondary seal made of a thermoplastic resin material or a reactive resin material between two glass plates 2a and 2b in advance on a processing table. The multi-layer glass 5 in which the space layer 4 is formed is horizontally positioned and fixed via the spacer 3 composed of the material 3b and the spacer member 3c, and can be swung to the sealing frame mounting portion on the peripheral portion of the multi-layer glass 5. The adhesive layer 10 made of the hot melt and the sealing frame body 6 extruded into a modified cross section made of a thermoplastic elastomer are simultaneously extruded and integrally bonded by a three-dimensional robot equipped with an appropriate discharge nozzle. .

  Note that the discharge nozzle of the three-dimensional robot is fixed at a predetermined position, and the adhesive layer 10 and the sealing frame 6 made of thermoplastic elastomer are simultaneously placed while rotating the multilayer glass 5 placed on the processing table. It is also possible to bond.

  In addition, when the sealing frame body 6 formed in a predetermined shape is attached to the sealing frame body mounting portion at the peripheral edge of the multilayer glass 5, an adhesive is applied to the sealing frame body mounting portion. Alternatively, the sealing frame 6 can be integrally bonded after being interposed.

It is also possible to mount the sealing frame bodies 6 divided via each of them.

  As described above, when the multilayer glass 5 is mounted on the sash frame 1 via the sealing frame 6, the adhesive layer 10 made of hot melt is applied to the sealing frame mounting portion at the peripheral edge of the multilayer glass 5. Since the sealing frame 6 extruded and formed into a certain shape from the extruder is integrally bonded at the same time, moisture such as rain water that has entered from the gap X between the sealing frame 6 and the multi-layer glass 5 is applied. Does not enter the portion of the secondary sealing material 3b, and therefore, it is possible to prevent dew condensation from occurring on the inner surfaces of the glass plates 2a and 2b of the multilayer glass 5.

  In addition, the attachment work of the sealing frame 6 (glazing channel) can be simplified, a lot of labor and work time can be shortened, and workability and productivity can be improved. Furthermore, since the glass edge part of the peripheral part of the multi-layer glass 5 can be protected by the sealing frame 6 and the cutting work for adjusting the dimensions is small, it can be a member that does not adversely affect the environment. .
