Description

  The present invention relates to a glazed multi-layer glass that surrounds a peripheral portion of a multi-layer glass used for a sash window for a house and the like, protects a glass end portion, and has a grechan (glazing channel) as a fitting means when fitted into a sash.

  In recent years, in order to obtain a more comfortable indoor environment by performing heat insulation and sound insulation with the outdoors, the spread of double-glazed glass that imparts excellent heat insulation performance and sound insulation performance to residential windows and the like is increasing.

  For example, in a detached custom-built house that is constructed and sold by a housing manufacturer, multi-layer glass is often used as a standard. Under such circumstances, the durability of the multilayer glass is improved, that is, the sealing property for preventing moisture from entering the hollow portion of the multilayer glass and becoming cloudy, or the multilayer glass will not be damaged. While protecting an edge part, it is desired to perform the assembly construction work to the sash frame of multilayer glass more simply and efficiently.

  As a means for protecting the glass plate end of the multi-layer glass and fitting it into a sash, there is a Grechan that surrounds the peripheral edge of the glass plate. Usually, Grechan is made by extrusion molding using a flexible and elastic polyvinyl chloride resin (hereinafter abbreviated as PVC).

  FIG. 4 is a cross-sectional view of a main part of an example in which a multi-layer glass is assembled to a sash through a Grechan.

  As shown in FIG. 4, the hard member 1 having a substantially U-shaped cross section that surrounds the peripheral side wall surface and the end surface of the multi-layer glass G is in contact with the multi-layer glass inscribed in the vicinity of the opening of the hard member 1. The Grechan GL in which the soft member 2 is integrally provided in the portion sandwiches and sandwiches the multilayer glass G and surrounds the multilayer glass G, and the sash frame S and the recess provided in the Grechan GL are fitted, When fitted, the flexible soft member 2 is pressed against the glass surface so that there is no gap, so that the water-tightness is obtained so that water does not enter from the outside. Can be securely assembled. Normally, the hard member 1 is made of a flexible but hard vinyl chloride, the soft member 2 is made of soft vinyl that is softer and more flexible than the hard member 1, and Grechan GL is formed into the shape by coextrusion molding. It is done.

  Moreover, when assembling to the entire peripheral surface and end surface of the multilayer glass G, the peripheral surface and the end surface are exposed at the corner portion in order to protect the peripheral surface and the end surface of the corner portion of the multilayer glass G that is most easily damaged. It is necessary to surround Grechan GL at the corner so as not to be present.

  FIG. 5 is a side view for explaining the procedure of surrounding the corner portion of the double-glazed glass with Grechan.

  Normally, as shown in FIG. 5, the go-around operation of the Grechan GL to the multilayer glass G is performed by cutting the Grechan GL at an angle of 45 degrees so as to decrease toward the inner side of the multilayer glass. After the adhesive is applied to the cut surface 3, the cut surface 3 is abutted and bonded. Conventionally, the surrounding operation of the corner portion of the multi-layer glass G using Grechan GL is performed by abutting the cut surface 3 to which the adhesive is applied and then fixing and adhering to the contacted state, thereby obtaining sufficient adhesive strength. It takes time, and the go of the corner is rate limiting. In particular, in order to use the double glazing G for an aluminum sash window for a house or the like, the surrounding work of the corner portion when the rectangular double glazing G surrounds the Grechan GL is the bottom of the Grechan GL for the aluminum sash window. Since the thickness of the wall and the side wall is as thin as about 1 mm, the application of the adhesive to the cut surface 3 and the adhesion by butting the Grechan GL must be carefully performed manually.

  The surrounding operation of the corner portion of the conventional double-glazed glass G using an adhesive is inevitably performed manually and takes time, and it takes time until the adhesive is solidified and the Grechan GL is completely joined. This is not efficient and increases the cost of glazed multi-layer glass, and even if a fast-drying adhesive with strong initial adhesion is used as the adhesive, the durability of the bonded part There is a problem that the bonded portion is easily detached over time. In particular, the hard member back portion 4 at the corner portion of Grechan is easy to come off and easily forms a gap.

  In order to prevent such a gap from occurring, a double-glazed glass with an attachment, in other words, a double-glazed glass with a grechant, is described in Patent Document 1 in which an adhesive tape is attached to and connected to the back 4 of the hard member at the corner. ing.

  On the other hand, as a means for rapidly joining the Grechan without taking time and effort, it is possible to use a handy type ultrasonic welding machine to weld and join the Grechan corner. When using a hand-held ultrasonic welder, when the glachan is surrounded by the multilayer glass, the operator presses the horn that transmits the vibration energy generated from the ultrasonic vibrator against the weld at the grechan corner. It is possible to generate frictional heat at the joining interface between the Grechans and to weld the corners instantly. However, sufficient strength cannot be obtained if the area of the welded portion at the time of ultrasonic welding is small.

In view of this, the present applicant disclosed in Patent Document 2 a grechant that encloses the peripheral surface and end surface of a rectangular glass plate and cuts the corner portion at an angle of 45 degrees and then abuts the opposite corner portions, and has a substantially cross-sectional shape. The soft member is integrally provided in the contact portion with the glass plate inscribed in the vicinity of the opening of the letter-shaped hard member, and the side wall of the hard member having a substantially U-shaped cross section has a double structure having a hollow portion, Cut the side wall into a 45 degree angle leaving a part of the side wall holding the hollow part in a shape that can be inserted into the hollow part of the opposing corner part side wall, and the remaining side wall part into the hollow part of the opposing side corner part Disclosed is an ultrasonic welding grechant characterized by ultrasonically welding an overlapped portion formed by insertion.
Registered Utility Model No. 3036478 JP 2003-120135 A

  The Grechan described in Patent Document 2 is a technical creation for wearing for ultrasonic waves, and has a double structure in which a hollow portion is provided on a Grechann side wall.

  It is an object of the present invention to provide a glazed multi-layer glass in which a grechan corner is ultrasonically welded to a sufficient bonding strength using a conventional grechan without using a double structure having a hollow portion on a grechan side wall. Objective.

  Furthermore, the present invention takes time and effort to make a conventional multi-glazed glass by enclosing the greachan in the double-glazed glass by bonding the cut grechans together and bonding them with an adhesive. An object of the present invention is to provide a glazed multi-glazed glass that is easy to manufacture by reducing the work of encircling the corner and using an ultrasonic welding machine.

  According to the present invention, a soft member is integrally formed in a contact portion between a hard member having a substantially U-shaped cross section surrounding a peripheral side wall surface and an end surface of a multilayer glass and a glass plate inscribed in the vicinity of the opening of the hard member. A multi-layer glass with a grecan surrounded by a grechan provided at the corner, wherein a plurality of protrusions are engaged with each other at a corner portion with the rear end of the substantially U-shaped hard member having a plurality of protrusions. After being fitted together, it is ultrasonically welded to join and surround the Grechan, and is a multilayer glass with Grechan.

  Furthermore, the present invention is the above-mentioned multi-glazed glass with a grechant, and when the plurality of protrusions are engaged with each other and fitted, the protrusion tips are exposed after being fitted so as to be exposed from the fitting portion. A multi-layer glass with a grechant, characterized in that the tip of the protrusion is fused with an ultrasonic wave.

  Furthermore, the present invention is the above-mentioned multi-glazed glass with a grechant, wherein the end of the soft member is obliquely cut so as not to overlap at the corner portion, and the hard member side wall having a substantially U-shaped cross section surrounding the peripheral side wall Is a double-glazed glass with a grechant, characterized in that it is cut so as to overlap, and the overlapping part of the side walls of the hard member is surrounded by ultrasonic welding.

  Furthermore, the present invention is the above-mentioned multilayer glass with a grechant, wherein the hard member side wall is overlapped with each other, and a notch is made between the back of the hard member and the hard member side wall. It is glass.

  The multi-layer glass with a grechant of the present invention, which is produced by enclosing the grechant in the corner portion of the multi-layer glass, is time-consuming and time-consuming to perform by bonding the cut grechant together and using an adhesive. Since the corner portion surrounding operation is performed using an ultrasonic welding machine, it can be completed easily in a short time, and the workability is improved, for example, and the fabrication becomes simple, and sufficient bonding strength is obtained at the corner portion.

  FIG. 1 is a plan view showing an example of the shape of the rear end of a hard member having a substantially U-shaped cross section when the Grechan corner portion is ultrasonically welded.

  As shown in FIG. 1, when the Grechan GL is ultrasonically welded at the corner of the multi-glazed glass with the Grechan of the present invention, the weld area is increased and the bonding strength is obtained. The end of the hard member back portion 4 has a structure having a plurality of protrusions 5, and the plurality of protrusions 5 are engaged and fitted. After the fitting, ultrasonic welding is performed to join Grechan GL.

  FIG. 2 is a side view for explaining the procedure for enclosing the corner portion by the grechan in the multi-glazed glass with the grechant of the present invention.

  As shown in FIG. 2, the procedure for surrounding the corner portion using the Grecan GL in the multilayer glass G is a structure having a plurality of protrusions 5 at the end of the hard member back portion 4 having a substantially U-shaped cross section, After engaging and fitting the protrusions 5, the horn 6 of the ultrasonic welding machine matched to the corner portion shape is brought close to the corner portion while pressing the ultrasonic wave, and the hard member back portion 4 is welded.

  When the corner portion is fitted, the hard member back portion 4 is fitted in an orthogonal state. Therefore, when the plurality of projections 5 are engaged and fitted, the tip of the projection 5 is exposed from the fitting portion. If the exposed portion is melted by an ultrasonic welding machine after the fitting, the ends of the fitting portions are fused together. In other words, when the ultrasonic welding is performed, the strong joining portion 7 that is strongly joined is obtained. In this way, compared with the conventional method in which the cut surface of the hard member back portion 4 is bonded with a butt adhesive without fitting and the Grechan GL is surrounded at the corner portion, the bonding strength is far greater. It becomes excellent, and there is no fear that the joint portion 7 of the hard member is peeled off.

  It is conceivable that both the hard member side wall 8 and the soft member 2 are cut at an angle of 45 degrees and bonded with an adhesive as in the prior art, but only the end of the soft member 2 is slanted so as not to overlap at the corner portion. The hard member side wall 8 having a substantially U-shaped cross section surrounding the peripheral side wall of the multilayer glass G is cut so as to overlap, and the overlapping portion of the hard member side wall 8 is ultrasonically welded. Since only ultrasonic welding is used, the preparation of the multi-glazed glass with a Grechan is simple.

  Moreover, in the site | part with which the said hard member side wall overlaps, if the notch 12 is made between the hard member back part 4 and the hard member side wall part 8, the soft member 2 cut diagonally when enclosing the corner part of the multilayer glass G will be shown. Therefore, it becomes easy to stack the soft members 2 so that there is no gap, and the soft members 2 need not be bonded.

  Next, the ultrasonic welding machine used in the present invention will be described.

  An ultrasonic welding machine that melts the boundary surface by friction between surfaces by vibration energy and welds and joins the hard member 1 of Grechan GL includes an ultrasonic oscillator, an ultrasonic vibrator, a pressurizing mechanism, a control system, a horn, It consists of a receiving jig and the like.

  There are two types of ultrasonic welders: handheld ultrasonic welding with a small output that can hold the horn that gives vibration energy so that the operator can press it against the object to be welded by hand. There is a high output air press type ultrasonic welding machine that applies vibration energy while pressurizing a welding target placed in a predetermined place of the receiving jig by an air press with a machine and a horn part fixed to the receiving jig.

  When producing the multi-layer glass with grechant according to the present invention, it is possible to obtain a sufficient bonding strength in a short time, and the handy that enables on-site work in the convenience of the work of enclosing the grechant GL in the multi-layer glass G. It is preferable to use a type ultrasonic welding machine. The air press mold must be installed at a predetermined place of the air press receiving jig when the Grechan 1 is assembled to the glass plate G. The maximum output of a commercially available handheld ultrasonic welder is about 200 W, and the maximum output of an air press type ultrasonic welder is about 1800 W. The multi-glazed multi-glazed glass of the present invention can be obtained in a short time by instantly welding the end fitting part of the back part 4 of the hard member to be ultrasonically welded and the overlapping part of the side wall 8 using a handheld ultrasonic welder. Easy to make.

  In addition, the glass sheet used for the multi-layer glass with a grechant of the present invention includes tempered glass, bent glass, glass with various functional films and colored glass, and the material of the glass sheet is a combination of inorganic and organic materials. It does not matter.

A multilayer glass G was prepared by sandwiching the aluminum spacer 10 between the peripheral edges and sealing the peripheral edge with a seal 11 material.

  Next, the multilayer member in which the soft member 2 is integrally provided at a contact portion between the hard member 1 having a substantially U-shaped cross section shown in FIG. 4 and the multilayer glass inscribed in the vicinity of the opening of the hard member. Grechan GL for enclosing glass G was prepared.

  In order to surround the corner portion of the multilayer glass G, as shown in FIG. 1, the end of the hard member back portion 4 having a substantially U-shaped cross section was press-cut so as to have a structure having a plurality of protrusions 5. When fitting at the corner portion, the hard member back portion 4 is fitted in an orthogonal state, so that when the plurality of projections 5 are engaged and fitted, the tip of the projection 5 is exposed from the fitting portion. It was a length. In addition, as shown in FIG. 2, only the soft member 2 is obliquely cut so as not to overlap at the corner portion, and the substantially U-shaped hard member side wall 8 surrounding the peripheral side wall of the multilayer glass G overlaps. I did it. Further, when ultrasonically welding the overlapped portion, it becomes easy to abut the soft member 2 so that there is no gap while correcting the deviation of the soft member 2 cut obliquely, so that the soft member is not bonded. A cut 12 was made between the hard member back 4 and the hard member side wall 8.

  A procedure for surrounding the corner portion of the multilayer glass G using Grechan GL will be described.
