Description

  The present invention relates to a crimping apparatus and a crimping method for a multi-layer glass window.

  From the viewpoint of heat insulation and soundproofing, a multi-layer glass window is frequently used as a glass window. The multi-layer glass window includes at least two glass plates and a spacer, the two glass plates are separated by a spacer, and both side surfaces of the spacer are bonded to the two glass plates by a primary sealing material. And it is comprised by sealing the edge part between two glass plates with a secondary sealing material.

  By the way, Patent Document 1 proposes to renovate the glass window into a multi-layer glass window by attaching a new glass plate with a spacer to an existing single-plate glass window constructed in a building. ing. By using the existing glass window as a part of the multi-layer glass window, there are advantages that the construction cost can be reduced, the construction period is shortened, the disposal of the existing glass window is unnecessary, and the sash is not required to be replaced.

  In the multilayer glass window of Patent Document 1, a glass plate with a spacer is attached to a glass window by bonding butyl rubber to the glass window via the spacer and then pressing the butyl rubber to the glass window. The crimping method was carried out by pressing a roller along the spacer from the surface of the glass plate with the spacer and running it.

  However, since butyl rubber has the property of repelling the pressing force of a roller applied instantaneously, it is difficult to reliably press the sealing material to the glass window by the pressing method using the roller. Therefore, Patent Document 2 proposes that the sealing material is pressure-bonded to the glass window by sucking air in the air layer and gradually pressing the sealing material against the glass window while decompressing the air layer. .

Further, as shown in FIG. 13B, even if two crimping jigs 104 are arranged along the upper and lower horizontal sides of the glass plate 12 with spacers, the surfaces of the four corners of the glass plate 12 with spacers are arranged. The glass window 16 can be pressed simultaneously. Moreover, you may arrange | position the crimping | compression-bonding jig | tool 104 along the diagonal of the glass plate 12 with a spacer. In this case, the two corners positioned at one diagonal are pressed first, and the butyl rubber 24 positioned at the two corners is pressure-bonded to the glass window 16, and then the two corners positioned at the other diagonal. This requires a two-step crimping operation.

  The crimping jig 104 of the embodiment can extend and contract the connecting member 120 in the axial direction by inserting and removing the pair of length adjusting members 124 with respect to the main body 122. Therefore, the length of the connecting member 120 can be adjusted to a length corresponding to the vertical side or the horizontal side of the glass plate 12 with a spacer.

  Further, according to the crimping jig 104, the suction member 118 is attached to the center portion of the main body 122, and the pressing member 116 is attached to the end portions of the pair of length adjustment members 124. Thereby, the reaction force of the force generated when the air layer 15 is depressurized, that is, the reaction force of the force that the glass plate 12 with a spacer tries to elastically deform (the drag force that prevents the elastic deformation of the glass plate 12 with a spacer), Transmission from the suction member 118 to the pair of pressing members 116 via the connecting member 120, and the pair of pressing members 116 simultaneously press the surfaces of the two corners of the glass plate 12 with spacers toward the glass window.

  Therefore, the reaction force can be used as the driving source without providing the pressing jig 104 with a driving source for pressing.

In other words, the attachment position of the suction cup 128 to the glass plate 12 with the spacer is preferably a central surface where the elastic deformation amount of the glass plate 12 with the spacer is large when the air layer 15 is depressurized. A corner portion where the elastic deformation of the glass plate 12 is small is preferable. The basic structure of the crimping jig 150 is the same as that of the crimping jig 104. The difference is that the connecting member 152 of the crimping jig 150 includes two main bodies 154 and 156, which are relatively rotatably connected.

  That is, the connecting member 152 includes a first main body 154 and a second main body 156 as shown in FIG. The first main body 154 and the second main body 156 are rotatably connected to each other via a shaft 158 connected to each central portion. A pair of length adjusting members 160 and 162 are inserted into the opening portions at both ends of the first main body 154 and the second main body 156 so as to be freely inserted and removed. A pressing member 116 is attached to the ends of the pair of length adjusting members 160 and 162, and an adsorption member 118 is attached to the center of the first main body 154.

  Next, a method for using the crimping jig 150 configured as described above will be described.

  First, the suction cups 128 of the pair of adsorption members 118 attached to the first main body 154 are adsorbed on the central portion of the entire glass plate 18 of the glass plate 12 with spacers. Next, the first main body 154 and the second main body 156 are rotated about the shaft 158, and the first main body 154 and the second main body 156 are angled along the diagonal line of the glass plate 12 with the spacer. To cross. Next, the positions of the pair of length adjusting members 160 and 162 attached to the first main body 154 and the second main body 156 are adjusted, and the length adjusting members 160 and 162 are attached to the pair of length adjusting members 160 and 162, respectively. A total of four head fittings 134 are brought into contact with the surfaces of the four corners of the glass plate 12 with spacers. Thereby, according to the crimping | compression-bonding jig | tool 150, the surface of the four corners of the glass plate 12 with a spacer can be simultaneously pressed on the glass window 16 with one crimping | compression-bonding jig 150. FIG.

  The crimping device of the embodiment has been described above, but the sealing material that is crimped to the glass window 16 by the crimping device is not limited to the butyl rubber 24. However, the butyl rubber 24 having the property of repelling a momentary large pressing force is suitable as a sealing material that presses against the glass window 16 while gradually increasing the pressing force of the pressing member 116.
