  By the way, each time a spacer is attached to a glass plate, the position of the spacer is determined by measuring with a gauge or using a scale, a gutter (mold plate) or the like. In addition, there are a plurality of types of spacers having different shapes such as L-shape and plate-shape, and which spacer is attached to which position has been confirmed by a construction method document prepared in advance.

  For this reason, it takes time for the work, and there is a concern that the attachment position may be mistaken or forgetting to stick.

  Accordingly, an object of the present invention is to provide a method for bonding a glass plate that can quickly and accurately attach a spacer to the glass plate.

  In order to achieve the above-mentioned object, the present invention provides a glass plate bonding method for attaching a glass plate to a peripheral edge of the glass plate in advance when bonding the glass plate to a window frame formed on a body. A mark for attaching the spacer is formed on the periphery of the plate, the spacer is attached with the mark as a target, and then the glass plate is bonded to the window frame.

  The spacer can be quickly and accurately attached to the glass plate.

(A) is the A section enlarged view of FIG. 1, (b) is the B section enlarged view of FIG. (A) is a perspective view of the state which gave the coating for adhesive protection to the glass plate, (b) is a perspective view of the state which apply | coated the adhesive agent to (a). It is the C section enlarged view of Drawing 3 (a). (A) is side sectional drawing of the window of a construction machinery cab rear part, (b) is a rear view of a construction machinery cab. (A), (b), (c) is the principal part enlarged view of the glass plate which shows the modification of a mark.

  Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

  FIG. 5A is a side cross-sectional view of the window (rear part) of the construction machine cab, where the left side of the drawing is the front and the lower side of the drawing is the lower side. FIG. 5B is a rear view of the construction machine cab before being assembled to the construction machine body.

  As shown to Fig.5 (a), (b), the window 2 is formed in the body 1 of the construction machine cab. The window 2 includes a window frame 3 formed on the body 1 and a glass plate 5 bonded to the window frame 3 with an adhesive 4.

  The window frame 3 is formed by forming a recess 6 for housing the glass plate 5 in the body 1 and forming an opening 7 in the recess 6. The recess 6 is formed by indenting a steel plate forming the wall surface of the body 1 inward. The recess 6 is bent at a substantially right angle with respect to the wall surface of the body 1 and is bent at a substantially right angle with respect to the outer frame 8 and extends into the frame of the outer frame 8. And an inner frame portion 9. The inner frame portion 9 is formed so as to face the glass plate 5 in the plate thickness direction when the glass plate 5 is accommodated in the window frame 3, and functions as an adhesion allowance for bonding the periphery of the glass plate 5. To do. The opening 7 is formed at the center of the inner frame portion 9.

  The glass plate 5 is formed in a shape corresponding to the window frame 3. As shown in FIG. 1, a protective film 10 for protecting the adhesive 4 from ultraviolet rays or the like is formed on the periphery of the glass plate 5, and a spacer for determining a space between the window frame 3 and the glass plate 5. 11a and 11b are attached. The glass plate 5 may have a shape that is appropriately curved according to the shape of the body 1.

  The protective film 10 is formed by applying black ceramic coating by silk printing (screen printing). As shown in FIG. 4, the protective film 10 is formed inwardly spaced from the outermost edge of the glass plate 5, and the transparent glass plate 5 is exposed on the glass plate 5 on the outer peripheral side of the protective film 10. A blank portion 12 is formed. The protective film 10 for protecting the adhesive 4 from ultraviolet rays is not limited to ceramic coating. Other adhesives may be used as long as the adhesive 4 can be protected from ultraviolet rays.

  As shown in FIG. 2, the spacers 11 a and 11 b have a plurality of types and have different mounting positions for each type. Specifically, the spacers 11a and 11b include an L-shaped spacer 11b formed in an L-shaped cross section and attached to the lower side of the glass plate 5, and a flat spacer formed in a flat plate shape and attached to the upper side of the glass plate 5. There are two types, 11a. The L-shaped spacer 11b is mounted along the lower end surface of the glass plate 5 and the surface on the inner frame portion 9 side, thereby positioning the glass plate 5 in the vertical direction and positioning in the horizontal direction (plate thickness direction). . The flat spacer 11a is positioned along the surface of the glass plate 5 on the inner frame portion 9 side to position the glass plate 5 in the horizontal direction. The L-shaped spacer 11b is longer than the flat spacer 11a so as not to be deformed with respect to the weight of the glass plate 5.

  Further, in particular, a mark 13 for attaching the spacers 11 a and 11 b is formed on the periphery of the glass plate 5.

  The mark 13 is formed simultaneously with the protective film 10 when the protective film 10 is formed, and is formed of a notch formed in the protective film 10. As shown in FIG. 4, the mark 13 is substantially V-shaped and has a shape in which all corners of the V-shape are rounded. The mark 13 is formed so as to be continuous with the blank portion 12 and can be easily found by following the boundary between the portion where the protective film 10 is formed and the blank portion 12.

  The marks 13 are formed as a pair at each spacer mounting position of the glass plate 5. These one-to-one set of marks 13 are formed apart from each other in the length direction of the spacers 11 a and 11 b, that is, in the direction along the peripheral edge of the glass plate 5. Further, the interval between the pair of marks 13 is set according to the lengths of the spacers 11a and 11b. As shown in FIGS. 2A and 2B, the one-to-one set of marks 13 is formed at the mounting position of the flat spacer 11a at an interval A slightly longer than the length of the flat spacer 11a. The spacer 11b is attached at a position B different from the position at which the flat spacer 11a is attached (an interval slightly longer than the length of the L-type spacer 11b). Thus, when the spacers 11a and 11b are attached to the glass plate 5, the attachment position can be easily recognized at the position of the mark 13, and it is easy to determine whether the L-type spacer 11b or the flat spacer 11a should be attached at the interval of the mark 13. It comes to understand.

  The mark 13 is not limited to the shape described above. For example, it may be a rectangular mark 14 as shown in FIG. 6 (a), a triangular mark 15 as shown in FIG. 6 (b), or as shown in FIG. 6 (c). The mark 16 having a shape imitating the cross-sectional shape of the spacers 11a and 11b may be used.

  In addition to the above-mentioned types of spacers, when these spacers are formed in various shapes to attach the glass plate 5 to the window frame 3, the mark is set in advance on the periphery of the glass plate 5. It is preferable that the spacer is formed so as to correspond to the various spacers so as to be attached at the predetermined position, and is formed so as to attach the spacer to the set position. In this case, the mark may be formed in a single position at the spacer mounting position, or may be formed in the same length as the spacer. In addition, it is desirable that the type of the mark can be easily distinguished because the shape is clearly different.

  Next, a method for bonding the glass plate 5 for bonding the glass plate 5 to the window frame 3 will be described.

  As shown in FIGS. 3 and 5, when the glass plate 5 is bonded to the window frame 3 of the body 1 such as a construction machine cab, first, a ceramic coating is applied to the periphery of the glass plate 5 by silk printing to form a protective film 10. Form.

  At this time, as shown in FIG. 4, the mark 13 is also formed by silk printing simultaneously with the protective film 10. The marks 13 are formed in a one-to-one pair at the mounting positions of the spacers 11a and 11b and spaced apart in the length direction of the spacers 11a and 11b. The distance between the pair of marks 13 is determined in advance according to the length of the spacers 11a and 11b to be attached. The interval between the one-to-one set of marks 13 is set to be different from the attachment position of the flat spacer 11a (for example, twice the interval) at the attachment position of the L-shaped spacer 11b. Because there is a large gap in the interval, the difference can be easily determined. Further, since the mark 13 is formed in the shape (contour shape) of the protective film 10 of ceramic coating that has been conventionally performed, the number of steps does not increase.

  Next, the adhesive 4 is applied to a predetermined position on the protective film 10. Here, the predetermined position is a position facing the inner frame portion 9 when the glass plate 5 is positioned in the window frame 3, and is located on the center side of the glass plate 5 from the mark 13 and attached later. , 11b.

  Thereafter, the flat spacer 11a and the L-shaped spacer 11b are attached to the glass plate 5 at preset positions. At this time, since a pair of marks 13 is formed at the spacer mounting position of the glass plate 5, the pair of marks 13 is targeted, and the spacers 11 a and 11 b are attached between these marks 13. Since the attachment position is clearly indicated by the mark 13, the attachment position can be accurately visually recognized without measuring with a gauge or using a scale, a gap, or the like. And the kind of spacer 11a, 11b which should be attached to an attachment position can be recognized easily and correctly by seeing the space | interval of the mark 13 without confirming with a construction method document.

  As shown in FIG. 1, when the flat spacer 11 a and the L-shaped spacer 11 b are attached to the glass plate 5, the glass plate 5 is pressed from the outside of the body 1 and bonded to the window frame 3. By attaching the flat spacer 11a and the L-shaped spacer 11b accurately without making a mistake in attaching positions or forgetting to attach them, the window frame 3 and the glass plate 5 can be bonded at an accurate interval.

  As described above, since the mark 13 for attaching the spacers 11a and 11b is formed in advance on the peripheral edge of the glass plate 5, the attaching operation of the spacers 11a and 11b can be performed in a short time, and the attachment position is wrong or forgotten to be attached. The spacers 11a and 11b can be quickly and accurately attached to the glass plate 5.

  Further, since the mark 13 is formed simultaneously with the protective film 10 when the protective film 10 is formed on the glass plate 5, the mark 13 can be formed without increasing the number of steps.

  A pair of marks 13 are formed apart from each other in the length direction of the spacers 11a and 11b, and the distance between the marks 13 is set according to the length of the spacers 11a and 11b. The spacers 11a and 11b can be attached to the glass plate 5 more easily and accurately.

  Since the mark 13 is formed by forming a notch in the protective film 10, it can be formed inexpensively and easily.

  The window frame 3 is not limited to the body 1 of the construction machine, and may be a body such as another vehicle.
