JP7443073B2 - Glass partition, its construction method, and correction tool - Google Patents

Description

The present invention relates to a glass partition installed in an office or the like and a construction method thereof.

BACKGROUND ART Various types of glass partitions in which a plurality of glass plates are arranged side by side in the width direction have been developed (see Patent Document 1).

By the way, in the conventional glass plate, a connecting member having, for example, an H-shaped planar cross section is interposed between the abutting ends of adjacent glass plates, and this connecting member positions and holds the ends of both glass plates. That's what I do.

However, such a connecting member is made of a material that is different from that of relatively wide glass, and is also provided continuously from the upper end of the glass plate to the lower end, so that adjacent glass plates are connected to the connecting member. This results in visual separation. Therefore, the connecting member becomes conspicuous, and the transparent area made of glass is unduly narrowed, which tends to reduce the basic visual performance of the glass partition (Problem 1).

Additionally, it has been pointed out that because a connecting member with an H-shaped planar cross section is interposed between adjacent glass plates, the order of construction is likely to be restricted and the degree of freedom in assembly work is low (Issue 2).

One embodiment of the present invention will be described below with reference to FIGS. 1 to 7.

As shown in FIGS. 1 to 3, the glass partition 1 of this embodiment is made up of a plurality of glass plates 2 arranged side by side in the width direction (arrow W direction in FIG. 1), and the adjacent glass plates 2 are butted. A correction tool 4 for suppressing warping of the glass plate 2 is partially provided at a specific location in the region 3. Specifically, this glass partition 1 has a plurality of glass plates 2, four in the illustrated example, arranged adjacent to each other in the width direction, and as shown in FIG. A vertically continuous gap 3s is formed in , and a correction tool 4 is disposed near the center of each gap 3s in the vertical direction. That is, the correction tool 4 is arranged at a position that can serve as a mark to prevent a person from accidentally colliding with the glass plate 2. Note that the arrow H in FIG. 1 indicates the vertical direction.

FIG. 4 shows an enlarged view of the abutment area 3 of two glass plates 2 that meet at the center of the glass partition 1 in the left-right direction. That is, in this drawing, for convenience of explanation, the left glass plate is labeled "2A" and the right glass plate is labeled "2B", and FIG. FIG. 4B is an enlarged side sectional view corresponding to section B in FIG. 3. FIG.

The straightening tool 4 placed between the adjacent glass plates 2A and 2B prevents warpage in the thickness direction (in the direction of arrow D in FIG. 4) near the abutting end surface 2e of the glass plate 2A and in the thickness direction near the abutting end surface 2e of the glass plate 2B. This is to prevent the gap 3s from unduly expanding due to the warpage of the gap 3s, and is mainly made of a rigid metal material. More specifically, as shown in FIGS. 4 and 7, the correction tool 4 includes a first exterior body 41 attached to one surface 2c of the adjacent glass plates 2A and 2B, and a first exterior body 41 attached to one surface 2c of the adjacent glass plates 2A and 2B. The second exterior body 42 is attached to the other surface 2d, and a connecting body 43 is inserted into the gap 3s and connects the two exterior bodies 41 and 42. As shown in FIGS. 4 to 7, the connecting body 43 includes an insertion plate 431 that protrudes from the inner surface 41a of the first exterior body 41 and is inserted into the gap 3s, and an insertion plate 431 that protrudes from the inner surface 42a of the second exterior body 42. The screw shaft 432 is screwed into a screw hole 433 provided in the insertion plate 431. As shown in FIGS. 4, 5, and 7, the first exterior body 41 and the insertion plate 431 are integrally made of a metal material such as stainless steel. Further, as shown in FIGS. 4, 6, and 7, the second exterior body 42 and the screw shaft 432 are also integrally made of a metal material such as stainless steel. Here, the vertical dimension of the insertion plate 431 from the upper end to the lower end is set to a value slightly smaller than the diameter of the first exterior body 41. The insertion plate 431 is divided into upper and lower parts, and a screw hole 433 is formed in the divided part. Note that a glass buffer material 411 is attached to the inner surface 41a of the first exterior body 41, and glass buffer materials 431 are attached to both sides of the insertion plate 431. Further, a glass buffer material 421 is also attached to the inner surface 42a of the second exterior body 42. These glass cushioning materials 411, 421, and 431 are for preventing the metal portion of the correction tool 4 from coming into direct contact with the glass plate 2. The first exterior body 41 and the second exterior body 42 each have a circular shape when viewed from the front, and the outer peripheries thereof are knurled or the like. The glass cushioning materials 411, 421, and 431 are sheet-like materials made of non-metallic materials such as resin that do not damage glass.

FIG. 5 is a diagram showing the first exterior body 41 and the insertion plate 431 that are made integrally, and FIG. 5(a) is a plan view, FIG. 5(b) is a front view, and FIG. 5(c) is a right side view. It is a diagram. FIG. 6 is a diagram showing the second exterior body 42 and the screw shaft 432 that are made integrally. FIG. 6(a) is a left side view, FIG. 6(b) is a front view, and FIG. 6(c) is a bottom view. It is a diagram.

A portion of the gap 3s where the connecting body 43 is not provided is filled with a filler material (not shown). Examples of the filler include transparent caulking materials, specifically silicone rubber materials. The width of the gap 3s is set smaller than the thickness of the glass plates 2A and 2B.

Although the above description is about the two glass plates 2A and 2B that abut each other at the center in the left-right direction, the same structure is adopted in all the abutting regions 3 of the adjacent glass plates 2. As shown in FIGS. 1 to 3, the upper edges of these glass plates 2 are supported by an existing structural member 50 placed on the ceiling while being held between an upper frame 51 and a ridge 52. The edge is supported by an existing structural member 60 placed on the floor while being held between a lower frame 61 and a ridge 62. Further, the outer edges of the glass plate 2 at both ends are supported by the upright structural member 70 while being held by the vertical frame 71.

The construction method of the glass partition 1 explained above is as follows.

That is, this glass partition 1 is constructed by a process of butting together a plurality of glass plates 2 through a gap 3s, a process of filling the gap 3s with a filler, and a process of inserting a correction tool 4 while partially removing the filler. A step of inserting the plate 431 into the gap 3s and attaching the first exterior body 41 to one surface 2c of both glass plates 2, and screwing the screw shaft 432 into the screw hole 433 of the insertion plate 431 inserted into the gap 3s. The second exterior body 42 is attached to the other surface 2d of both glass plates 2.

With such a configuration, not only can the presence of the straightening tool 4 effectively suppress the relative deformation of the abutted glass plates 2 in the thickness direction, but also the straightening tool 4 can partially Compared to conventional glass plates that are provided continuously from the top to the bottom of the glass plate, the degree to which adjacent glass plates 2 are visually separated is reduced, and the transparency of the glass is reduced. It is possible to prevent the area from being unduly narrowed. Therefore, it is possible to achieve a high level of basic visual performance as a glass partition, which is good translucency.

Further, since the portion of the gap 3s where the connecting body 43 is not arranged is filled with a filler (not shown), airtightness and sound insulation in the space partitioned by the glass partition 1 can be ensured. In particular, in this embodiment, a silicone rubber-based transparent caulking material can be used as the filler, so airtightness and sound insulation can be ensured without compromising the basic visual performance of a glass partition, which is good light transmission. can.

Furthermore, the connecting body 43 is provided on the insertion plate 431 that projects from the inner surface 41a of the first exterior body 41 and is inserted into the gap 3s, and on the insertion plate 431 that projects from the inner surface 42a of the second exterior body 42. Since it is equipped with a screw shaft 432 that is screwed into a screw hole 433, it is easier to fill the gap 3s compared to the conventional method in which a connecting member having an H-shaped flat cross section is interposed between adjacent glass plates. After the step of filling the material, the step of inserting the insertion plate 431 of the correction tool 4 into the gap 3s while partially removing the filler may be performed, or before the step of filling the gap 3s with the filler. Since it is also possible to perform the step of inserting the insertion plate 431 of the correction tool 4 into the gap 3s, there are fewer restrictions on the order of construction, and the degree of freedom in the assembly work can be improved.

In addition, according to the configuration of the correction tool 4 according to this embodiment, both the left and right sides of the insertion plate 431 can be used as joint width guides, and the insertion plate 431 provided with the screw hole 433 can be inserted between the glass plates 2. It is also easy to tighten the screw by fixing it in a predetermined position and rotating only the male screw formed by the second exterior body 42 and the screw shaft 432.

Then, the correction tool 4 is located at a position where it can serve as a mark to prevent a person from accidentally colliding with the glass plate 2, specifically, for example, in the case of a glass partition 1 with a height of 3,000 mm, the correction tool 4 is located above and below the gap 3s. Since it is placed near the center of the direction, that is, at a height of 1,500 mm from the bottom edge, it is possible to make those passing near the glass partition 1 aware of the presence of the glass partition 1, and the passerby can notice the presence of the glass partition 1. It is possible to suppress the occurrence of problems such as accidental collisions. However, the height position from the lower end of the correction tool 4 is not limited to 1,500 mm, but the above-mentioned effects can be obtained if it is set in the range of 1,000 to 2,000 mm.

Note that the present invention is not limited to the embodiments described above.

That is, the present invention is applicable to all glass partitions in which a plurality of glass plates are arranged adjacent to each other in the width direction. By the way, when a fire breaks out near a glass partition, the warping of the glass plates caused by the heating of the glass plates, as well as the formation of large gaps between the glass plates caused by the warping of the glass plates, can be suppressed by the straightening tool, and flames can be prevented. Intrusion beyond the glass partition into the compartment divided by the glass partition can be suppressed. In this case, a plurality of correction tools may be vertically spaced apart from each other in a gap between a glass plate provided at both ends in the width direction, that is, both left and right ends, and a glass plate adjacent to the glass plate. As a guideline for the distance between the correction tools to obtain fireproof performance, for example, 1,600 mm can be cited. Further, if the glass plate is fireproof and heat resistant, further fireproofing performance can be obtained.

Furthermore, the connecting body that connects the first and second exterior bodies of the correction tool is not limited to the one described in the above-mentioned embodiments, and the connection body that connects the first and second exterior bodies of the correction tool is not limited to the one described in the above-mentioned embodiment. If it is equipped with a connecting body, it is possible to reduce restrictions on the order of construction and improve the degree of freedom in assembly work.

An example of a correction tool having such a connecting body is shown in FIG. 8. In this case, the connecting body 43 includes an insertion plate 431 which is protruded from the inner surface 41a of the first exterior body 41 and inserted into the gap 3s between the abutting end surfaces 2e of the adjacent glass plates 2A and 2B, and the second exterior body 41. The correction tool B4 includes a rivet 435 that projects from the inner surface 42a of the body 42 and is inserted into a rivet insertion hole 436 provided in the insertion plate 431. This correction tool B4 holds the first and second exterior fittings 41 and 42 in a state attached to the one surface 2c and the other surface 2d of the glass plates 2A and 2B, respectively, by caulking the tips 435a of the rivets 435. It looks like this.

Another example is as shown in FIG. In this case, the connecting body 43 is provided with an insertion plate 431 that protrudes from the inner surface 41a of the first exterior body 41 and is inserted into the gap s2 between the abutting end surfaces 2e of the adjacent glass plates 2A and 2B, and a second exterior body. An orthodontic correction comprising an engaging protrusion 437 that protrudes from the inner surface 42a of the body 42 and has a locking claw 437a at its tip that can engage a locking groove 439 in an engaging hole 438 provided in the insertion plate 431. This is ingredient C4. The correction tool C4 is attached by first inserting the insertion plate 431 into the gap 3s, and then inserting the engagement protrusion 438 into the engagement hole 436. During the process of inserting the engagement protrusion 438 into the engagement hole 436, the tip of the engagement protrusion 438 is elastically deformed and retreats inward, and the locking claw 439 of the engagement protrusion 438 is inserted into the locking groove 437. When the corresponding position is reached, the tip of the engagement protrusion 438 elastically returns, and the locking pawl 439 engages with the locking groove 437.

8 and 9 are enlarged views of the abutment area 3 of the two glass plates 2 in each embodiment, and both FIGS. 8(a) and 9(a) correspond to FIG. 4(a). However, both FIG. 8(b) and FIG. 9(b) correspond to FIG. 4(b). In the embodiment shown in FIGS. 8 and 9, the other parts are the same as those in the embodiment described above with reference to FIGS. 1 to 7, so the same reference numerals are omitted and the explanation will be omitted.

In constructing a glass partition equipped with these correction tools B4 and C4, either the step of filling the filler or the step of arranging the connected body of the correction tools B4 and C4 in the gap 3s may be performed first. It is possible to reduce restrictions on the construction order and improve the degree of freedom in assembly work.

Of course, it is also possible to adopt a correction tool in which the connecting body and the first and second exterior bodies are integrated. An example is as shown in FIG. This thing includes a first exterior body 41 having a rectangular plate shape, a second exterior body 42 having a rectangular plate shape parallel to this first exterior body 41, and these first and second exterior bodies 41. , 42, and a connecting body 43 that connects the correction tool D4 has an H-shaped cross section.

A glass partition equipped with such a correction tool D4 is corrected by a step of butting a plurality of glass plates 2A and 2B together through a gap 3s, and by using the gap 3s when butting the glass plates 2A and 2B. It is constructed by passing through the steps of interposing the tool D4 between the glass plates 2A and 2B, and filling the gap 3s with a filler while holding the correction tool D4 at a required position.

FIG. 10 shows an enlarged view of the abutment area 3 of the two glass plates 2 in this reference example . FIG. 10(a) corresponds to FIG. 4(a), and FIG. 10(b) corresponds to FIG. Corresponds to b). In the reference example shown in FIG. 10, the other parts are the same as those in the embodiment described above with reference to FIGS. 1 to 7, so the same reference numerals are omitted and the explanation is omitted.

If such a correction tool D4 is used, since the entire correction tool D4 is integrally formed, it is possible not only to reduce the number of parts and the number of assembly steps, but also to easily manufacture the correction tool D4. I can do it. That is, such a correction tool D4 can be easily made by sequentially cutting a long extruded material having an H-shaped cross section at required locations.

In the embodiment described above, adjacent glass plates are designed to ensure airtightness and sound insulation in the space partitioned by the glass partition while not impairing the basic visual performance of the glass partition, which is good light transmission. Although a silicone rubber caulking material is filled in the continuous gap between the abutting end faces of the caulking material, any material may be used for the caulking material, and a filler other than the caulking material may be used.

The number and arrangement of correction tools may also be set arbitrarily. However, as in the embodiment described above, if the correction tool is placed in a position that can serve as a landmark to prevent people from accidentally colliding with the glass plate, people passing near the glass partition will be able to see the glass partition. Since the presence of the glass partition can be recognized, it is possible to suppress the occurrence of a problem in which the passerby accidentally collides with the glass partition.

In addition, various modifications may be made without departing from the spirit of the present invention.
