Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass wall connecting fixture for a curtain wall used for connecting a support structure and a glass wall when forming a curtain wall.

[0002]

2. Description of the Related Art Conventionally, a glass wall made of tempered glass or a mirror made of tempered glass has been used in order to enhance the appearance of the wall surface of a building or the like. When constructing a glass wall of this kind, mechanical strength is not sufficient for a glass wall having a large area, and therefore, a method of fitting a glass or a mirror to a frame material made of a material having high rigidity such as metal is often used. There is.

However, when the above frame material is used, a frame material having a width of about 40 to 100 mm is exposed on the wall surface. Therefore, by eliminating such a frame material,
In recent years, a glass wall referred to as a curtain wall has been constructed as a glass wall having a more beautiful appearance.

In the curtain wall, as shown in the perspective view seen from the lower outer side in FIG. 1, the multi-layered glass walls 1, 1 ...
However, they are gathered so that their surroundings face each other. In this case, packing or caulking material is arranged between the edge portions of the glass walls 1 and 1, but the width between the edge edges is extremely small compared to the case where a frame material made of metal or the like is used. Therefore, the appearance of the wall surface can be effectively enhanced.

By the way, when constructing the curtain wall, it is necessary to connect each glass wall 1 to a support structure disposed inside the wall surface. In the example of FIG. 1, a plurality of glass wall connecting fixtures are used. 2 is used to connect the glass wall 1 to the support structure (not shown).

An example of the structure of the conventional glass wall connecting fixture 2 will be described with reference to FIGS. FIG. 2 is an exploded perspective view of the glass wall connecting fixture 2 together with the glass wall 1 and the mounting plate 3 which is a part of the support structure. FIG. FIG. 6 is a vertical cross-sectional view showing a state in which it is connected and fixed to a mounting plate 3.

The glass wall connecting fixture 2 has a substantially cylindrical main body 4 made of stainless steel or the like. A bolt insertion hole 4a extending in a direction connecting the glass wall 1 and the mounting plate 3 is formed at the center of the main body 4.

The main body 4 has an inner surface 1 of the glass wall 1.
It is arranged between a and the inner surface 3a of the mounting plate 3. Also,
The glass wall 1 is formed with a through hole 1c that is tapered so that its diameter is increased on the outer surface 1b side. The collar 5 is inserted into the through hole 1c,
A fixing bolt 6 is inserted in the collar 5 and the main body 4. On the other hand, a nut 7 is arranged on the outer surface 3b side of the mounting plate 3, and the glass wall 1 is connected and fixed to the mounting plate 3 by screwing the nut 7 onto the bolt 6.
Note that 8a to 8d represent elastic packing made of rubber or synthetic resin.

Although the mounting plate 3 is shown as a substantially L-shaped member in FIG. 2, it is actually fixed and integrated to a support structure fixed to the ground or another portion. Is.

The process of connecting and fixing the glass wall 1 to the mounting plate 3 using the connecting fixture 2 will be described. First, in front of the through hole 3c of the mounting plate 3, the through hole 1 of the glass wall 1
The glass wall 1 is positioned so that the center of c coincides with the center of the through hole 3c. In this case, the operator holds the glass wall 1 by hand and holds the glass wall 1 so that the positions of the through hole 3c and the through hole 1c overlap each other. While the operator keeps the glass wall 1 positioned in the above state,
The body 4 and the elastic packings 8a, 8b are inserted between the glass wall 1 and the mounting plate 3, and the position of the body 4 is determined so that the through holes 1c, 3c and the through hole 4a of the body 4 coincide with each other. . Then, the collar 5 is attached to the through hole 1c of the glass wall 1.
Then, the bolt 6 is inserted from the side of the glass wall 1 to project from the outer surface 3b of the mounting plate 3. Next, the glass wall 1 is fixed to the mounting plate 3 by mounting the nut 7 and tightening the bolt 6.

Further, as shown in FIG. 4, in the portion where the four glass walls 1, 1, 1, 1 are adjacent to each other, the mounting plates 3 and 3 each having a size extending over the plurality of glass walls 1 are provided. A plurality of glass walls 1 are arranged and fixed to each mounting plate 3 by the glass wall connecting fixture 2.

[0012]

However, in the above-mentioned conventional curtain wall construction method, a large number of parts must be prepared in a disassembled state prior to connecting and fixing the glass wall 1 to the mounting plate 3 of the support structure. I had to. That is, as the components constituting the glass wall connecting fixture 2, a tubular body 4, a collar 5, bolts 6, nuts 7,
The elastic packings 8a to 8d and the like had to be prepared in a separated state. Further, at the time of construction, each of the above-mentioned members prepared in a disassembled state had to be taken out from the parts storage box or the parts storage bag at the construction site and assembled after positioning the glass wall 1. Therefore, while maintaining the state of positioning the glass wall 1 during assembly,
Since it is necessary to assemble many parts of the connecting fixture,
There was a problem that the work at the time of construction was very complicated.

Also, in the conventional curtain wall construction method,
When connecting and fixing the glass wall 1 to the mounting plate 3, the operator must hold the glass wall 1 in a predetermined position until the bolt 6 is inserted, the nut 7 is attached, and the bolt 6 is tightened. That is, from the state where the glass wall 1 is positioned so that the through hole 1c of the glass wall 1 is located in front of the through hole 3c of the support portion 3 until the process of tightening the bolt 6 is completed, a plurality of workers perform a heavy glass wall Had to hold one. Therefore, when constructing the curtain wall using the glass wall 1, a plurality of workers are required to hold the glass wall 1, and yet another worker is required to tighten the bolts 6 and the nuts 7. I had no choice but to need.

Therefore, since the work efficiency in constructing the curtain wall is low and a large number of workers are required, the construction period is long and the construction cost is very high.

The object of the present invention is that it is not necessary to assemble a large number of parts during the work of connecting glass walls at the construction site, and the construction of the curtain wall can be performed efficiently and easily by a small number of workers, and therefore the construction period can be reduced. It is an object of the present invention to provide a glass wall connecting fixture for a curtain wall, which can effectively reduce the construction cost and the construction cost.

[0016]

According to a first aspect of the present invention, in a curtain wall construction method, a glass wall connecting fixture for connecting and fixing a glass wall to a support structure having a mounting plate provided with a through hole. A flange portion arranged outside the through hole of the mounting plate, and a bolt insertion hole provided at the center so as to extend in the longitudinal direction, and inserted into the through hole formed in the mounting plate. Fixed
A tubular body extending from the through hole to a through hole provided in the glass wall; a bolt inserted into the bolt insertion hole of the tubular body from the glass wall side; and a tubular body side. And a female screw portion for fixing a glass wall to the tubular body by being screwed with the bolt, and the tip of the tubular body on the glass wall side is the glass wall. It is a glass wall connecting fixture for a curtain wall having a diameter that allows it to enter the through hole.

Further, in the glass wall connecting fixture for a curtain wall according to the present invention, as described in claim 2, preferably, the tubular main body is connected to the flange portion, and inside the through hole of the glass wall. To an inner cylinder, and an outer cylinder that is externally inserted in the inner cylinder and is arranged between the glass wall and the mounting surface, and by fixing the inner cylinder and the outer cylinder to each other, Cylindrical body fixing means for fixing the cylindrical body to the support structure is further provided.

[0018]

In the glass wall connecting fixture for a curtain wall according to the first aspect of the present invention, the tubular body is inserted and fixed in the through hole of the mounting plate of the support structure.

Therefore, the work of connecting the glass walls can be performed in a state where the above-mentioned cylindrical main body is previously integrated with the mounting plate. Therefore, when connecting and fixing the support structure and the glass wall, the through hole of the glass wall is positioned in front of the tip of the tubular body so that the tip of the tubular body can be directly inserted into the through hole of the glass wall. In addition, the glass wall can be positioned by moving the glass wall.

After the positioning of the glass wall is completed, the glass wall is locked by the tip of the cylindrical main body that has entered the through hole. Therefore, after inserting the tip ends of the tubular main bodies of the plurality of connecting fixtures into the plurality of through holes of the glass wall and positioning the glass wall, there is no fear that the glass wall will drop downwards. The operator only needs to hold it down to prevent the glass wall from tipping over.

When fixing the glass wall, after the above-mentioned positioning is performed, a bolt is inserted into the bolt insertion hole of the tubular body from the outer surface side of the glass wall, and outside the flange portion of the tubular body, All you have to do is install the nut and tighten the bolt.

[0022]

When the glass wall connecting fixture for curtain wall of the present invention is used, most of the members of the glass wall connecting fixture are previously fixed and integrated to the support structure side, so that the glass wall can be handled. The work of can be simplified. Also, the glass wall is positioned so that the tip of the tubular body of the glass wall connecting fixture is inserted into the through hole of the glass wall, and the glass wall is used as a support by a simple work step of tightening with a bolt and a nut. Can be connected. Moreover, since the glass wall is locked at the tip of the tubular body, the work of holding the glass wall after positioning the glass wall can be easily performed.

Therefore, the efficiency of the work of fixing the glass wall at the construction site can be greatly improved, and the curtain wall can be constructed by a small number of workers and in a short period of time. Further, when the elastic packing made of silicone rubber is arranged between the cylindrical body and the mounting plate and between the mounting plate and the flange portion of the cylindrical body as in the invention described in claim 3, Even when the support structure side vibrates strongly due to an earthquake or the like, the transmission of the vibration to the glass wall side can be effectively suppressed.

It is provided to suppress the transmission of vibration between the outer cylinder 26 and the glass wall 1.

From the outside of the glass wall 1, collars 35, 3
6 is arranged in the through hole 1a of the glass wall 1, and the bolt 37 is inserted in that state. Each member of the glass wall connecting fixture for the curtain wall of the present embodiment is as described above,
The structure will be clarified by explaining the construction method of the glass wall connecting fixture.

At the time of construction, first, the glass wall connecting fixture 11 shown in FIG. 5 is prepared. In this case, the mounting plate 1
The above-mentioned members (excluding the glass wall 1) shown in FIG. 6 are fixed in advance to the upright wall 12b. That is, FIG.
As shown in, the inner cylinder 25 and the outer cylinder 26, which form a cylindrical main body, are attached to the upright wall 12b of the mounting plate 12 via elastic packings 27 and 28. In this case, the pair of pins 29a and 29b described above from above the outer cylinder 26.
(See FIG. 6) is inserted and the outer cylinder 26 and the inner cylinder 25 are fixed to the upright wall 12b.

An elastic packing 34 is externally inserted in front of the outer cylinder 26, as shown in FIG. Further, as is clear from FIG. 11, the elastic packing 33 described above is externally inserted into the small-diameter protruding portion 25c at the tip of the inner cylinder 25. Further, as is apparent from FIG. 5, the collars 35 and 36 are arranged in front of the elastic packing 34, and the bolt 37 is inserted from the front side, so that the flange portion 2
A nut 32 is attached to the bolt 37 at the rear of 5a.

Therefore, when connecting and fixing the glass wall to the mounting plate using the glass wall connecting and fixing device for the curtain wall of this embodiment, first, the glass wall connecting and fixing device 11 shown in FIG. Fixed to.

Next, the glass wall connecting fixture 1 shown in FIG.
From 1 above, the bolt 37, the collars 35 and 36, the washer 30, the spring washer 31 (see FIG. 6), and the nut 32 are removed. In this state, the structure excluding the glass wall 1 shown in FIG. 11 is realized. That is, a structure is obtained in which the inner cylinder 25 and the outer cylinder 26 forming the cylindrical body are fixed to the upright wall 12b of the mounting plate 12 together with the elastic packings 27, 28, 33, 34.

In this state, the glass wall 1 to be connected (see FIG.
The glass wall 1 is positioned so that the through hole 1c (see 1) corresponds to the tip of the inner cylinder 25. After that, the glass wall 1 is moved to the glass wall connecting fixture side, and the through hole 1c
The inner tube 25 is positioned so that the tip of the inner tube 25 is inserted therein. As is clear from FIG. 11, when the tip of the inner cylinder 25 is inserted into the through hole 1a of the glass wall 1, the glass wall 1 is attached to the inner wall of the through hole 1a by the tip portion of the inner cylinder 25 (main body). In the example, it will be locked (via the elastic packing 33).

Therefore, in the plurality of through holes 1a, as shown in FIG.
In the state where the front end of the glass wall connecting fixture is inserted and positioned as shown in FIG. 1, the glass wall 1 no longer falls as it is. Therefore, after the glass wall 1 is positioned in the state shown in FIG. 11, the glass wall 1 can be kept in that state only by one worker holding the glass wall 1 so as not to fall.

Next, continuing from the state shown in FIG. 11, the collars 35 and 36 and the bolt 37 shown in FIG. 6 are attached from the front of the glass wall 1 and extended outside the flange portion 25a of the inner cylinder 25. The bolt 37, the washer 30, the spring washer 31, and the nut 32 shown in FIG.
7 and tightening the bolts 37
As shown in FIG. 10, the glass wall 1 can be fixed to the glass wall connecting fixture for curtain wall of this embodiment. That is, the glass wall 1 can be connected and fixed to the support structure by connecting and fixing the glass wall 1 to the glass wall connecting fixture of the present embodiment which is previously fixed to the mounting plate.

As is apparent from the above construction method, when the glass wall connecting fixture for curtain wall of this embodiment is used, the connecting fixture is first connected to the support structure side. In this state, all the members necessary for connecting and fixing the glass wall are prepared. That is, as shown in FIG. 5, the bolts 37 necessary for fixing together with the inner cylinder 25, the outer cylinder 26, and the like.
All the small parts such as the nut and the nut 32 are prepared and set in advance. Therefore, when connecting and fixing the glass walls, it is not necessary to carry small parts separately, and it is possible to omit the complicated work of taking out the necessary parts from the parts container or the like.

Moreover, when fixing the glass wall 5 from the state shown in FIG. 5, the above-mentioned various washers 30 are used.
The bolt 37 and the nut 32 are removed, the glass wall is positioned with respect to the tip of the inner cylinder 25, and the through hole 1 of the glass wall 1
The glass wall is fixed only by positioning so that the tip of the inner cylinder 25 is inserted into the inside of c, attaching the bolts 37 and nuts 32 that have been removed, and tightening the bolts 37. Therefore, the glass wall can be connected and fixed to the support by an extremely simple process.

In addition, conventionally, when constructing a curtain wall, even after a plurality of workers hold a heavy glass wall in their hands and perform positioning with respect to the support and the connecting fixture, the plurality of glass walls are held. While the operator had to hold the glass wall, when the glass wall connecting fixture of the present embodiment is used, the glass wall is locked by the tip portion of the inner cylinder 25, and therefore the positioning is performed. There is no need to lift the glass wall after completion. Therefore, since the posture of the glass wall after positioning can be maintained by one worker, the curtain wall can be constructed by a small number of workers,
As a result, it is possible to shorten the construction period of the curtain wall and reduce the construction cost.

Further, the glass wall connecting fixture 11 of the present embodiment.
Since the tubular main body is fixed to the upright wall 12b of the mounting plate 12 via the elastic packings 27 and 28 made of silicon rubber, the case where the support body and the mounting plate vibrate due to an earthquake or the like occurs. Also, it is possible to effectively prevent the transmission of the vibration to the glass wall side. Similarly, the inner cylinder 2
Also at the tip portion of 5, the transmission of vibrations between the inner cylinder and the glass wall 1 is prevented by the elastic packing 33 described above, so that breakage of the glass wall can be effectively prevented.

When the glass wall connecting fixture 11 of this embodiment is fixed to the mounting plate (FIG. 5), the position of the cylindrical body 24 or the like may deviate from the intended position. In such a case, the mounting plate 12 shown in FIG.
In FIG. 14, the mounting plates 12 to 14 are formed by forming the through holes of the portions to which the bolts 16, 17, 20, 21 and the nuts 18, 19, 22, 23 are mounted in a long hole shape extending in the front-rear direction and the lateral direction. The position of the glass wall relative to the support structure can be adjusted, whereby the glass wall can be positioned easily and reliably at the construction site with respect to the support structure.

In the curtain wall glass wall connecting fixture 11 shown in FIG. 5, one glass wall connecting fixture 11 is used for the mounting plates 12 to 14. As described above, the present invention is not limited to the arrangement of one glass wall connecting fixture on one mounting plate. For example, in FIG.
Two glass wall connecting fixtures 11 may be arranged on the mounting plate 42, as shown in a schematic partial plan sectional view of FIG. 11A and a front view of the same seen from the front in FIG. Here, the mounting plate 42 is configured by joining L-shaped metal plates 41A and 41B. The portion of the mounting plate 42 where the glass wall connecting fixture 11 is attached is shown in FIG.
As shown in the front view of FIG. 9B when viewed from the front, through holes 42a and 42b having a long hole shape are formed in the vertical direction. Therefore, when the glass wall 1 is fixed, even if the height of the pair of through holes on the glass wall 1 side varies, the glass wall connecting fixture is attached to the through holes 42a and 42b having the long hole shape. 11
By adjusting the height at which the glass is fixed, it is possible to absorb the variation in the height of the through hole of the glass wall.

As shown in FIG. 12, the mounting plate 4
The structure in which a plurality of glass wall connecting fixtures 11 are attached to 2 is effective after being used, for example, in a portion for connecting and fixing adjacent glass walls.

Referring to FIGS. 13 to 15, the second embodiment of the present invention is described.
The glass wall connecting fixture for curtain wall according to the embodiment will be described. FIG. 13 is a partially cutaway sectional view showing a state in which the glass wall 1 is connected and fixed to the mounting plate 12 by using the glass wall connecting fixture 51A of the second embodiment, and FIG. It is a figure equivalent to. Therefore, the same parts as those in FIG. 10 are designated by the same reference numerals, and the description thereof will be omitted.

In the glass wall connecting fixture 51 of the second embodiment, the cylindrical body 54 has an inner cylinder 55 and an outer cylinder 56.
In the present embodiment, a female screw 55e is formed on the flange portion 55a side portion of the bolt insertion hole 55d provided at the center of the inner cylinder 55. The female screw 55e is configured to be screwed with the bolt 37. Therefore, in the glass wall connecting fixture 51 of the present embodiment, the internal thread 55e can be formed without using the nut 32 arranged outside the flange portion 55a.
Then, the glass wall 1 is fixed to the tubular main body 54 by screwing with the bolt 37. However, in this embodiment, the nut 32 is used in addition to the female screw 55e. Therefore, since both the internal thread 55e and the nut 32 form the internal thread part of the present invention, the bolt 37 is more effectively tightened to the tubular body 54 by the so-called double nut effect, and thereby the glass wall. 1 is more firmly fixed.

However, the nut 32 may be omitted, and the bolt 26 may be fastened to the cylindrical main body 54 only by the female screw 55e. Further, the glass wall connecting fixture 51 of the present embodiment.
Then, a male screw 55f is formed on the outer peripheral surface of the tubular main body of the inner cylinder 55 (see FIG. 15), while a female screw 56 screwed to the male screw 55f is formed on the inner peripheral surface of the through hole of the outer cylinder 56.
b is formed. Therefore, the inner cylinder 55 and the outer cylinder 56 are fixed to each other by screwing the male screw 55f and the female screw 56b together. That is, while the inner cylinder 55 is inserted into the through hole of the mounting plate 12, the outer cylinder 56 is screwed onto the inner cylinder 55 to fix them to each other.
The tubular body 54 can be fixed to the mounting plate 12.

Therefore, in this embodiment, since the male screw 55f and the female screw 56b are used as the structure for fixing the tubular main body to the mounting plate 12, the pins 29a and 29b are fixed as in the first embodiment. It is not necessary, and it is not necessary to machine a groove or the like on the outer cylinder.

Further, in the present embodiment, a pair of through holes 55g, 55g are formed in the flange portion 55a of the inner cylinder 55 in order to prepare the work for fixing the outer cylinder 56 to the inner cylinder 55. (See Figure 14). The through holes 55g and 55g are
It is provided so that the flange portion 55a can be easily rotated by a wrench having a protrusion that is inserted into the pair of through holes 55g, 55g. Therefore, the through hole 55
Instead of g and 55g, a recess into which the projection of the tool can be inserted may be formed.
