Description

[Technical field]

[0001] The present invention relates to a partition wall to be installed in an office or the like, and a construction method thereof. [Background technology]

[0002] Various partition walls of this type have been developed, which consist of multiple panels arranged side by side in the width direction between a ceiling rail and a floor rail, and some of these panels are made entirely or partially of transparent glass.

[0003] In the case of a glass plate used as the face plate, for example, the inner surface of the upper edge of the glass plate is attached to the outer surface of the side wall of an upper frame supported by a ceiling rail, and a glass ridge is attached to the outer surface of the upper edge of the glass plate. The upper edge of the glass plate is held in a clamped state by fastening the glass ridge to the upper frame or the ceiling rail. Similarly, the inner surface of the lower edge of the glass plate is attached to the outer surface of the side wall of a lower frame supported by a ceiling rail, and a glass ridge is attached to the outer surface of the lower edge of the glass plate. The lower edge of the glass plate is held in a clamped state by fastening the glass ridge to the lower frame or floor rail.

[0004] However, in the conventional glass panels, for example, the glass pressing edge that presses the upper edge (lower edge) of the adjacent glass panel is simply engaged with the upper frame (lower frame) or ceiling rail (floor rail) via a concave-convex engagement part. Therefore, when the glass panel is subjected to a temperature change or a large external force, the concave-convex engagement part may come off.

[0005] To prevent such problems, a glass bezel has been developed in which the tip is extended upward (downward) and the tip is screwed to the upper frame (lower frame) (see, for example, Patent Document 1). However, when the glass bezel is screwed to avoid the glass plate, a relatively large joint tends to be formed between the upper edge (lower edge) of the glass plate and the ceiling surface (floor surface), and this also leads to problems such as an increase in the number of parts and an increase in the labor required for assembly and disassembly.

The upper bracket 42 and the lower bracket are normal, so detailed explanations will be omitted.

[0025] A horizontal frame 5 (hereinafter sometimes referred to as "upper frame 5A") is fitted and screwed to the lower side of the ceiling rail 1 as shown in FIG. 2, and a horizontal frame 5 (hereinafter sometimes referred to as "lower frame 5B") is fitted and screwed to the upper side of the floor rail 2 as shown in the same figure. As shown in FIG. 2 and FIG. 5, the horizontal frame 5 is integrally provided with a flat groove-shaped horizontal wall 51, side walls 52 extending perpendicularly from both sides of the horizontal wall 51, and an extension wall 53 extending horizontally from the outer surfaces 52a of the side walls 52. The inner surfaces 52b of the both side walls 52 of the horizontal frame 5 that constitute the upper frame 5A are abutted against the outer surfaces 12a of the both side walls 12 of the ceiling rail 1, and the inner surfaces 52b of the both side walls 52 of the horizontal frame 5 that constitute the lower frame 5B are abutted against the outer surfaces 22a of the both side walls 22 of the floor rail 2. As shown in Fig. 6, each horizontal frame 5 in this embodiment has a length twice the width dimension (unit width dimension) of the glass plate 7. Furthermore, as shown in Fig. 5, a packing 54 made of an elastic material such as rubber is disposed between the outer surface 52a of the side wall 52 and the glass plate 7. The extending end of the extending wall 53 has a large thickness, a horizontal groove 53a is provided in the center in the thickness direction, and a raised step 53b is provided at the boundary with the base end 53c. C1 is a horizontal frame cover that conceals the horizontal frame 5.

[0026] Furthermore, as shown in Figures 2, 4 to 7 and 9, the partition wall W in this embodiment comprises two glass plates 7 with the inner edges attached to the outer surfaces 52a of the side walls 52 of the horizontal frame 5, and a glass boss 8 attached to the outer edges of the glass plates 7. The glass boss 8 is engaged with the horizontal frame 5 via the engagement portion K, so that the glass plate 7 is sandwiched between the horizontal frame 5 and the glass boss 8. The tip edge 52c of the side walls 52 of the horizontal frame 5 and the tip edge 83 of the glass boss 8 are arranged in parallel, and a fastening bracket 9 is fitted externally from the tip side to both tip edges 52c, 83 to prevent both tip edges 52c, 83 from moving apart from each other.

[0027] More specifically, as described above and as shown in Fig. 1 and Fig. 6, the glass plates 7 are rectangular, each having a width dimension of one unit, and as described above, the inner edges of the glass plates 7 are attached to the horizontal frames 5 that form the upper frame 5A and the horizontal frames 5 that form the lower frame 5B. A caulking material 74 is disposed between the two glass plates 7, as shown in Fig. 3. Each glass plate 7 in this embodiment is a so-called laminated glass, in which an adhesive layer 73 is interposed between a front glass layer 71 and a rear glass layer 72.

[0028] 2 and 5, the glass pressing edge 8 includes a vertical plate portion 81 having a glass pressing portion 811 at one end that is in contact with the outer surface of the edge of the glass plate 7, a horizontal plate portion 82 extending inward from the other end of the vertical plate portion 81, a tip edge portion 83 extending from the extending end of the horizontal plate portion 82 parallel to the side wall 52 of the horizontal frame 5, and a horizontal protrusion 84 extending inward from the vertical plate portion 81 and capable of engaging with a horizontal groove 53a provided in the horizontal frame 5. At least a portion of the horizontal plate portion 82 is in contact with the extending wall 53 of the horizontal frame 5, and an engaging claw 85 is provided at the extending end thereof that is capable of engaging with a raised step portion 53b of the extending wall 53 of the horizontal frame 5. The outer surface of the horizontal plate portion 82 is an engaging surface 82a that can come into contact with a stopper 94 of the fastener 9 described later.

[0029] The engagement portion K is for fastening the glass embossing 8 to the horizontal frame 5. As shown in FIG. 5, the main engagement element K1 engages with the leading edge 83 of the glass embossing 8 in the direction of approaching and separating from the leading edge 52c of the horizontal frame 5, and engages with the leading edge 83 of the glass embossing 8 by utilizing temporary deformation of the member just before the main engagement element K1 is completed. frame5 and a secondary engagement element K2 which enhances the engagement state with the glass boss 8. The primary engagement element K1 is arranged to fit a horizontal groove 53a provided at the extended end of the extended wall 53 of the horizontal frame 5 into a horizontal protrusion 84 provided on the glass boss 8. The secondary engagement element K2 is arranged at a position where the fastener 9 can prevent temporary deformation of the member during engagement / disengagement (in this embodiment, deformation such as the horizontal plate portion 82 of the glass boss 8 moving upward (see FIG. 11)). Specifically, the secondary engagement element K2 is arranged to engage a raised step portion 53b provided in the middle of the extended wall 53 of the horizontal frame 5 with an engagement claw 85 provided on the glass boss 8.

[0030] As shown in Fig. 5 and Fig. 8, the fastener 9 includes a pair of clamping pieces 91, 92 that clamp the leading edge 52c of the side wall 52 of the horizontal frame 5 and the leading edge 83 of the glass press 8, and a connecting piece 93 that connects the base ends of the clamping pieces 91, 92, and is integrally formed from, for example, a spring steel plate. In this embodiment, the fastener is attached to the upper end of the boundary X between two adjacent glass plates 7 on the left and right. In addition, the fastener 9 includes a stopper 94 at the leading end of one of the clamping pieces 91 that abuts against the locking surface 82a (the outer surface of the horizontal plate portion 82) formed on the glass press 8, and is configured so that a gap S is formed between the connecting piece 93 and both leading edges 52c, 83 when the stopper 94 abuts against the locking surface 82a, as shown in Fig. 5 and Fig. 13. The pair of clamping pieces 91, 92 approach each other as they move away from the connecting piece 93, i.e., toward the bottom in Fig. 5. The fastener 9 has a window 91a in one of the clamping pieces 91 that communicates the gap S with the outside.

[0031] As shown in Fig. 3, a vertical frame 6 is fitted and screwed to the glass plate 7 side of the intermediate support 4. The vertical frame 6 is integrally provided with an upright wall 61 having a long and narrow plate shape, side walls 62 extending from the vicinity of both front and rear ends of the upright wall 61 in a direction perpendicular to the glass plate 7, and extending walls 63 extending from both front and rear ends of the upright wall 61 in a direction perpendicular to the glass plate 7 and facing away from the glass plate 7. A packing 64 made of an elastic material such as rubber is disposed between the outer surface of the side wall 62 of the vertical frame 6 and the glass plate 7. The inner surface of the extending wall 63 of the vertical frame 6 is attached to the outer surface of the side wall of the support body 41 of the intermediate support 4. In addition, a vertical glass holder H is attached to the outer surface of the side edge of the glass plate 7, and the base end H1 of the vertical glass holder H is engaged with a vertical groove 63a provided on the outer surface of the extension wall 63 of the vertical frame 6, so that the glass plate is additionally held down by the vertical frame 6 and the vertical glass holder H. C2 is a vertical frame cover that conceals the vertical frame 6.

[0032] Here, the glass plate 7 is attached in the following procedure with reference to FIG.

[0033] First, as shown in Fig. 9, the glass plate 7 is attached to the packing 54 provided on the outer surface 52a of the side wall 52 of the horizontal frame 5. Then, as shown in Figs. 10 and 11, the horizontal plate portion 82 of the glass boss 8 is elastically deformed while engaging the primary engagement element K1. That is, the horizontal protrusion 84 of the glass boss 8 is inserted into the horizontal groove 53a of the extension wall 53 of the horizontal frame 5. Thereafter, the entire horizontal protrusion 84 is inserted into the horizontal groove 53a, and the horizontal plate portion 82 is elastically restored to engage the secondary engagement element K2. That is, the state is reached in which the engagement claw 85 is elastically engaged with the raised step portion 53b of the extension wall 53 of the horizontal frame 5, as shown in Fig. 12. Then, the other clamping piece 92 of the fastening bracket 9 is inserted between the side wall 12 of the ceiling rail 1 and the side wall 52 of the cross frame 5 (upper frame 5A) until the stopper 94 of the fastening bracket 9 abuts the engaging surface 82a of the glass edge 8, resulting in the state shown in Figure 13.

[0034] Here, FIG. 1 is a front view showing the partition wall W of this embodiment. FIG. 2 is a cross-sectional view taken along line AA in FIG. 1, and FIG. 3 is a cross-sectional view taken along line BB in FIG. 1. FIG. 4 is an enlarged view of part C in FIG. 1, and FIG. 5 is an enlarged view of part D in FIG. 2. FIG. 6 is an exploded perspective view showing the mounting mode of the glass plate 7 and the glass pressing edge 8 in the partition wall W, with the glass plate 7 and the glass pressing edge 8 on one side (the back side in FIG. 6) omitted. FIG. 7 is an exploded perspective view showing the mounting mode of the glass plate 7 and the glass pressing edge 8 in the partition wall W, with the upper part enlarged. FIG. 8(a) is a perspective view showing the fastener 9, FIG. 8(b) is a plan view showing the fastener 9, FIG. 8(c) is a front view showing the fastener 9, FIG. 8(d) is a right side view showing the fastener 9, and FIG. 8(e) is a rear view showing the fastener 9. FIG. 9 to FIG. 13 are explanatory views showing the mounting procedure of the glass pressing edge 8 and the fastener 9.

[0035] With this configuration, the leading edge 52c of the side wall 52 of the horizontal frame 5 and the leading edge 83 of the glass press 8 are arranged in parallel, and the fastener 9 is fitted from the leading end to both leading edges 52c, 83. Therefore, even if an external force acts on the glass plate 7 in a direction away from the horizontal frame 5, the clamping force of the fastener 9 can prevent both leading edges 52c, 83 from moving apart from each other. frame This effectively prevents the glass plate 7 from coming off the cross frame 5 due to the glass edge 8 being disengaged from the cross frame 5.

[0036] Moreover, in this embodiment, the fasteners 9 are disposed across the upper ends of the boundary portions X of the adjacent glass plates 7 on the left and right, so that the common fasteners 9 can effectively prevent the two adjacent glass plates 7 from separating. In particular, when the glass plates 7 expand due to a fire or the like, the butt joints of the glass plates 7 push against each other and bulge outward, and the glass plates 7 tend to start separating from these joints, but the partition wall W can effectively prevent this phenomenon from occurring.

[0037] In addition, in this embodiment, the glass ridge 7 is fixed to the horizontal frame 5 via the engagement portion K, so the number of parts can be reasonably reduced compared to when the glass ridge 7 is screwed to the horizontal frame 5, the ceiling rail 1, etc. using multiple bolts. Furthermore, when a screw fastening structure is adopted, the leading edge portion 52c of the side wall 52 of the horizontal frame 5 and the leading edge portion 83 of the glass ridge 8 tend to be longer in the vertical direction due to the provision of screw holes. Therefore, the joint width between the upper edge of the glass plate 7 and the ceiling surface must be large, but in this embodiment, it is only necessary to cover both leading edges 52c, 83 with the fastening metal fittings 9, so the occurrence of such a defect can be suppressed.

[0038] Furthermore, the engagement portion K of this embodiment not only includes a main engagement element K1 (horizontal groove 53a and horizontal protrusion 84) that engages with the leading edge 52c of the side wall 52 of the horizontal frame 5 and the leading edge 83 of the glass press 8 in the direction of approaching and separating, but also includes a secondary engagement element K2 (engagement claw 85 and raised step 53b) that utilizes temporary deformation of the member to engage and strengthen the engagement state of the glass press 8 with the horizontal frame 5 just before the main engagement element K1 finishes engaging. Therefore, even if the glass press 8 is not screwed, the glass press 8 can be strongly prevented from coming off the horizontal frame 5. Moreover, in this configuration, if the secondary engagement element K2 is provided at a position where the temporary deformation of the member during engagement and disengagement can be prevented by the above-mentioned fastener 9, it is possible to prevent the fastener 9 from being required to have high strength, and the initial purpose can be achieved with a small fastener 9. In other words, with this configuration, the fastening member 9 only needs to prevent the secondary engagement element K2 from coming off, so that no large load acts on the fastening member 9, and the small fastening member 9 can effectively prevent the glass edge 8 from coming off.

[0039] Specifically, in this embodiment, the glass boss 8 is installed in the correct position to press the glass plate 7 through the process shown in Fig. 9 to Fig. 13, and is fixed by the fastener 9. That is, when the glass boss 8 is moved toward the glass plate 7 from the initial state shown in Fig. 9, the horizontal protrusion 84 of the main engagement element K1 provided on the glass boss 8 is fitted into the horizontal groove 53a of the main engagement element K1 provided on the extension wall 53 of the cross frame 5 as shown in Fig. 10. Then, when the glass boss 8 is further pressed toward the glass plate 7, the horizontal protrusion 84 further enters the horizontal groove 53a, and just before the main engagement element K1 finishes engaging, the engagement claw 85 provided on the tip of the horizontal plate portion 82 of the glass boss 8 overcomes the raised step portion 53b by utilizing the temporary deformation of the horizontal plate portion 82 (member) as shown in Fig. 11, and the horizontal plate portion 82 elastically returns to the initial state as shown in Fig. 12, and the engagement claw 85 engages with the raised step portion 53b. During this process, the tip edge 83 integrated with the tip of the horizontal plate portion 82 temporarily tilts outward. Therefore, after the horizontal plate portion 82 elastically returns to its initial state and the secondary engagement element K2 enters an engaged state, if a fastener 9 is fitted externally to the tip edge 83 integrated with the tip of the horizontal plate portion and the tip edge 52c of the side wall 52 of the cross frame 5 to prevent the two tip edges 52c, 83 from separating, the reverse movement of the above-mentioned mounting operation is prevented, and the secondary engagement element K2 can be prevented from disengaging.

[0040] In addition, the fastener 9 includes a pair of clamping pieces 91, 92 that clamp the leading edge 52c of the side wall 52 of the cross frame 5 and the leading edge 83 of the glass press 8, and a connecting piece 93 that connects the base ends of the clamping pieces 91, 92, so that the fastener 9 can be easily formed as an integral member. If the fastener 9 of this embodiment is integrally formed from a spring steel plate, the fastener 9 can be made thin and small while still ensuring strength.

[0041] Furthermore, the fastening fitting 9 is provided with a stopper 94 at the tip of one of the clamping pieces 91 which abuts against the engagement surface 82a formed on the glass bezel 8, and is configured so that when the stopper 94 abuts against the engagement surface 82a, a gap S is formed between the connection piece 93 and the side wall 52 of the cross frame 5 and the tip edge portions 52c, 83 of the glass bezel 8.Therefore, the fastening fitting 9 can be easily removed by inserting a tool such as a flat-head screwdriver into this gap S.

[0042] The fastening fitting 9 has a window 91a in one of the clamping pieces 91 which connects the gap S to the outside, and this window 91a can be used to insert a tool such as a flat-head screwdriver, making the removal operation even easier.

[0043] The present invention is not limited to the above-described embodiment.

[0044] For example, the configuration of the partition wall is not limited to that of the above-mentioned embodiment, and the number of glass plates may be three or more. frame There is no need to splice on both sides of the frame Of course, the present invention may be applied to a partition wall in which a glass plate is attached to only one side of the partition wall.

[0045] In the above-described embodiment, the fasteners are attached only to the upper edges of the adjacent glass sheets on the left and right, but it is of course also possible to attach fasteners only to the lower edges of the glass sheets, or to both the upper and lower edges.

[0046] The engaging portion may be composed of only a primary engaging element, but if it is provided with a secondary engaging element as in the above embodiment, the load acting on the fastener can be significantly reduced, and the object of the present invention can be achieved with a small fastener as described above. Also, various configurations of the primary engaging element may be adopted. Furthermore, in the case of a portion provided with a secondary engaging element, various configurations of the secondary engaging element may be adopted.

[0047] The shape, material, and other configuration of the fastener may be variously adopted as long as it does not impair the gist of the present invention, even if it is different from that of the embodiment described above. However, if it is integrally formed from spring steel plate as in the embodiment described above, it is possible to make such a fastener thin and small while ensuring strength as described above. Also, if the fastener has a stopper that engages with the engagement surface formed on the glass embossing as in the embodiment described above, and is configured so that gaps are formed between the fastener and the side wall of the cross frame and both end edges of the glass embossing when the stopper is engaged with the engagement surface, it is possible to easily remove such a fastener as described above.

[0048] In addition, various modifications may be made without departing from the spirit of the present invention. [Explanation of symbols]
