[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembling structure of an outer wall glass of a building and a construction method thereof, and more particularly, to an SSG.
(Structural Sealant Glazing System) A building called the construction method, in which the glass sheets that make up the windows and outer walls of the building are bonded and fixed to supporting members placed inside the room via a silicone adhesive filler. The present invention relates to an assembling structure of an outer wall glass and a method of constructing the same.

[0002]

2. Description of the Related Art In recent years, sheet glass constituting windows and outer walls of buildings has been cooled by using a room temperature vulcanized silicone-based structural sealant.
SSG (St) that is adhesively fixed to a support member placed on the indoor side and safely supports and fixes against various external forces applied to the glass sheet
A construction method called the “ructural sealant glazing system” has been developed and is already in practical use.

FIGS. 26 and 27 respectively show the above SS
The example of the assembly structure of the outer wall glass comprised by the G construction method is shown. In FIG. 26, reference numeral 1 denotes a plate glass constituting an outer wall of a building, 2 denotes a back mullion (supporting member) which is disposed on the indoor side and substantially supports the plate glass 1, and 3 denotes a position between the plate glass 1 and the back mullion 2. Adhesive filler for interposing and bonding the plate glass 1 to the back mullion 2 is provided.
A sealing material 5 for waterproofing provided at the joint is a backup material for filling a portion between the sheet glass 1 and the back mullion 2 where the adhesive filler 3 is not interposed. Here, the back mullion 2 is made of, for example, an aluminum alloy, the adhesive filler is vulcanized silicone rubber (structural sealant) at room temperature (room temperature), and the backup material 5 is, for example, a polyethylene foam or a chloroprene molded body. It is. The assembly structure shown in FIG. 27 has a mechanism 6 for following the interlayer displacement of a building. The same components as those shown in FIG. 26 are denoted by the same reference numerals. In FIG. 27, an interlayer displacement follow-up mechanism 6 for absorbing an interlayer displacement in a building caused by an external force is provided by a clearance of a bonding member (support member) 2 ′ attached to the back mullion 2. The plate glass 1 is bonded and fixed to the mold 2 ′ via the adhesive filler 3.

[0004] According to the above-described structure of the outer wall glass assembled by the SSG construction method, it is possible to form a flat appearance in which the frame of the sash is not seen outside the building. There is an effect that a design aiming at a mirror effect over the entire outer surface of the building can be made.

[0005] Fabrication of the assembly structure by the SSG construction method as described above is performed by one of 1) factory fabrication, 2) simple factory fabrication in which a floor or the like of a construction site is a temporary factory, and 3) field fabrication. I have. Among them, in the factory production and the simple factory production, the glass plate 1 and the mold 2 ′ are fixed in advance to produce a unit (SSG unit), and the mold 2 ′ of the unit is attached to the back mullion 2. It is common. On the other hand, in the case of on-site production, the back mullion 2 is first erected in the structure of the building, and then the sheet glass 1 is attached, and the gap between the back mullion 2 and the sheet glass 1 is filled with the adhesive filler 3. The filling of the adhesive filler 3 is performed by, for example, a manual sealing gun or an air gun using compressed air.

[0006]

However, the above conventional structure for assembling the outer wall glass and the construction method thereof have the following disadvantages or points to be improved. That is, in the case of the factory-manufactured product of 1), using the well-equipped equipment, applying the adhesive filler 3 in an ideal environment,
Curing, inspection, etc. can be performed, and a high quality SSG unit can be manufactured. However, i) the adhesive filler 3 uses a room temperature vulcanized silicone sealant as described above, and cures slowly (depending on the temperature and humidity). Approximately three days to one month), which occupies a large hardening space for a long period of time, ii) low productivity makes it impossible to meet large orders, iii) expensive due to i and ii. ,
And so on. Also, in the case of 2) simple factory production, as in the case of factory production, it is not affected by vibration or wind pressure during the curing process, and it is manufactured at a construction site and is cheaper than factory production. However, i) also requires a large curing space due to the slow curing of the adhesive filler. Ii) Differences in temperature and humidity due to seasonal and daily weather, and formation of floors. In addition, dew condensation tends to occur on the adherend surface due to the effect of moisture coming out of the concrete, and dust and the like are also likely to adhere, so that it is difficult to ensure uniform and stable adhesive strength. In addition, in the case of 3), it can be manufactured most easily and inexpensively. On the other hand, i) it is difficult to secure a stable adhesive strength due to the influence of weather conditions.
The adhesive filler during the curing process is adversely affected by the influence of vibration and the like. iii) Since the joint depth is large, it is difficult to perform sufficient cleaning, uniform primer application, and reliable filling, and there is a problem that adhesion failure or filling failure may occur.

The present invention has been made in view of the above circumstances, and can fix the glass sheet 1 and the supporting member 2 firmly and quickly in a short time, thereby solving the above-mentioned disadvantages. An object of the present invention is to provide an assembling structure of an outer wall glass of a building and a method of constructing the same.

Embodiments of the present invention will be described below with reference to the drawings. First, referring to FIGS.
An embodiment of the invention according to claim 3 will be described. This embodiment
As shown in FIG. 1, the glass plate 1 is bonded to a support member [back mullion 2 or a mold 2 '(in the illustrated example, back mullion)] in the outer wall glass assembling structure previously shown in FIG. 26 as an example. The filling adhesive 3 for fixing
Was a NetsuKa硫silicone rubber 10, and is applied to a case constituting the filler bonding material 3 by extrusion molding.

The filling adhesive 3 comprising the heat-cured silicone rubber 10 according to the present embodiment is obtained by extruding an unvulcanized silicone rubber into a predetermined cross-sectional shape and then heat-curing the same. .

Hereinafter, a method for manufacturing the above-described structure for mounting the outer wall glass will be described. In the drawings shown below, the sectional shape of the bonding mold 2 'is slightly different from that of FIG. 27, and the illustration of the backup material and the sealing material is omitted except for some drawings. .

FIGS. 2 to 4 are process charts showing the first method. This first method is suitable for factory production or simple factory production in which the sheet glass 1 and the bonding mold 2 'are previously configured as an integrated unit. First, FIG.
As shown in the figure, an unvulcanized silicone rubber 9 is extruded to a predetermined cross-sectional shape and dimensions by an extruder and adhered to the outer surface 2a of the mold member (support member) 2 ', that is, the surface on which the sheet glass 1 is to be mounted. At this time, the outer surface 2a of the mold 2 '
It is preferred that the surface to be provided with the unvulcanized silicone rubber is subjected to a primer coating treatment if necessary. Next, as shown in FIG. 3, the plate glass 1 is pressure-bonded to the unvulcanized silicone rubber 9 attached to the mold member 2 'to form a unit (SSG unit) 12 in which the plate glass 1 and the mold member 2' are integrated. I do. Also in this case, the surface to be adhered of the glass sheet 1 may be subjected to a primer treatment as necessary. Thereafter, as shown in FIG. 4, the unit 12 is placed in a vulcanization chamber (not shown), and the unvulcanized silicone rubber 9 is subjected to a heat vulcanization treatment to obtain a heat vulcanized silicone rubber 10. The heating in the vulcanization chamber is preferably performed at, for example, 120 ° C. for 30 minutes or 150 ° C. for about 15 minutes.

According to the above method, the adhesive filler 3 is provided on the mold (support member) 2 'by extrusion molding.
The operation of applying the adhesive filler 3 can be performed continuously and efficiently, and the thickness and the like can be freely set. In addition, the adhesive filler 3 can be completely cured in a very short time, and the adhesive strength of the conventional adhesive filler 3 made of room temperature vulcanized silicone rubber is 7 to 7 in terms of adhesive strength.
While 12 kgf / cm was about ² can be obtained remarkably large value such 20~60Kgf / cm ^2. Further, this method is suitable for factory production or simple factory production, but since the adhesive filler 3 is completely hardened in such an extremely short time, a curing place is not required.

Next, FIGS. 5 to 7 are process charts showing the second method. This second method also includes a sheet glass 1 and a mold 2 '.
Are pre-configured as an integrated unit for factory production or simple factory production. In the second method, as shown in FIG. 5, first, an unvulcanized silicone rubber 9 is attached to both the mold 2 'and the sheet glass 1 by extrusion. The unvulcanized silicone rubber 9 may be formed by rolling into a sheet. It is preferable to apply a primer coating treatment to the surface of the plate glass 1 and the mold member 2 ′ to which the unvulcanized silicone rubber 9 is adhered. Next, as shown in FIG. 6, the sheet glass 1 provided with the unvulcanized silicone rubber 9 and the mold 2 'are pressed together with the unvulcanized silicone rubber 9 attached thereto, and the unit 12 is pressed. To form Thereafter, as shown in FIG. 7, the unit 12 is placed in a vulcanization chamber and thermally vulcanized, so that the unvulcanized silicone rubber 9 becomes a thermally vulcanized silicone rubber 10. According to the second method, the same operation and effect as those of the first method can be obtained.

Next, FIGS. 8 to 11 are process diagrams showing the third method. This third method is also suitable for factory production or simple factory production in which the sheet glass 1 and the mold 2 'are integrated as a unit in advance. In this method, similarly to the first and second methods, first, as shown in FIG. 8, an unvulcanized silicone rubber 9 is applied to the outer surface 2a of the mold 2 '.
The (first unvulcanized silicone rubber 9A) is extruded into a predetermined cross-sectional shape and dimensions by an extruder or a roll-forming machine and adhered. If necessary, the surface to be coated is coated with a primer. Next, the mold 2 'provided with the first unvulcanized silicone rubber 9A is put into a vulcanization chamber,
This first unvulcanized silicone rubber 9A is referred to as a thermally vulcanized silicone rubber 10 as shown in FIG. On the other hand, the unvulcanized silicone rubber 9 (the second unvulcanized silicone rubber 9)
B) is extruded and adhered to a predetermined cross-sectional shape and dimensions (primer coating is applied to the surface to be adhered if necessary), and then, as shown in FIG. The unit 12 is constituted by bonding together the heat-cured silicone rubber 10. here,
The second unvulcanized silicone rubber 9B provided on the plate glass 1 side is thinner than the heat-vulcanized silicone rubber 10 and is a so-called tape-like one. In the present invention, since the unvulcanized silicone rubber 9 is formed by extrusion molding or rolling molding as described above, the thickness and the like can be easily set as described above. Thereafter, as shown in FIG. 11, the unit 12 is placed in a vulcanization chamber, and the second unvulcanized silicone rubber 9B is thermally vulcanized to obtain a thermally vulcanized silicone rubber 10.

In the above method, the structure for mounting the outer wall glass as shown in FIG. 1 can be realized.
Since it is hardened in an extremely short time, the work can be made much more efficient and a curing place can be made unnecessary. Further, since the adhesive filler 3 (unvulcanized silicone rubber 9) is formed by extrusion molding or roll molding, the operation of attaching the adhesive filler 3 can be performed continuously and efficiently, and its thickness and the like can be freely adjusted. For example, it is easy to form a tape like the second unvulcanized silicone rubber 9B.

Next, referring to FIGS.
An embodiment of the invention according to claim 5 will be described. FIG.
14 to 14 are process diagrams showing a fourth method. In addition,
The mounting structure constituted by the fourth method is the same as the structure shown in FIG. 1 in that the glass sheet 1 is attached to a support member (back mullion 2, shape member 2 ', etc.) via an adhesive filler 3. However, as shown in FIG.
The structure shown in FIG. 1 is different from the structure shown in FIG. First, as shown in FIG. 12, an unvulcanized silicone rubber 9 is extruded to a predetermined cross-sectional shape and size by an extruder and adhered to a sheet glass 1. If necessary, the surface to be coated is treated with a primer. In this case, as shown in the figure, the unvulcanized silicone rubber 9 has a groove 13 for engaging a support member such as the back mullion 2 or the mold member 2 ′ and has an H-shaped cross section. . On the other hand, the supporting members such as the back mullion 2, the mold member 2 'and the like are formed with concave grooves 14 which can be engaged with the unvulcanized silicone rubber 9 as shown in FIG. As described above, the unvulcanized silicone rubber 9 is applied to the sheet glass 1
After being bonded and fixed to the vulcanization chamber, it is placed in a vulcanization chamber and thermally vulcanized, and the unvulcanized silicone rubber 9 is converted into a thermally vulcanized silicone rubber 10 as shown in FIG. Thereafter, the sheet glass 1 is attached to the support member by fitting the heat-vulcanized silicone rubber 10 (adhesive filler 3) into the support member 2 such as the mold member 2 '.

In the above method, of course, factory production is performed,
Since the fixing between the glass sheet 1 and the support member 2 is substantially a fitting and fixing, the on-site construction is possible in which the shape member 2 ′ is built in the site in advance. Also, when the adhesive filler 3 is formed in an H-shape as described above, it can be formed very easily because the unvulcanized silicone rubber 9 is formed by extrusion molding. Further, in the above-described assembly structure, only the fixing of the sheet glass 1 and the adhesive filler 3 is adhesively fixed, and therefore, the adhesion between the adhesive filler 3 and the support member such as the mold member 2 'is considered in consideration of the adhesive reliability. It is not necessary to do so, and it is possible to reduce the labor and the like related to the adhesive strength.
In the above structure, the adhesive filler 3 and the mold 2 'are used.
In fixing with a support member such as described above, a structure may be employed in which the locking structure is used as described above and the two are further adhered.

Next, FIGS. 15 to 18 show a fifth method. In the fifth method, similarly to the fourth method, the adhesive filler 3 is fitted into the support member 2. First, as shown in FIG. 15, the unvulcanized silicone rubber 9 is extruded into an H shape. Next, the unvulcanized silicone rubber 9 is thermally vulcanized in a vulcanization chamber to obtain a thermally vulcanized silicone rubber 10 as shown in FIG. On the other hand, a tape-shaped unvulcanized silicone rubber 9 extruded or roll-formed is fixed to the side of the glass sheet 1 (primer coating is applied to the surface to be adhered if necessary). The silicone rubber 10 is pressed and fixed to the tape-shaped unvulcanized silicone rubber 9. Thereafter, the plate glass 1 to which the unvulcanized silicone rubber 9 and the heat-vulcanized silicone rubber 10 are fixed is put into a vulcanization chamber, and the unvulcanized silicone rubber 9 is made into the heat-vulcanized silicone rubber 10. Thereafter, as shown in FIG. 18, the sheet glass 1 is attached to the supporting member by fitting the heat-vulcanized silicone rubber 10 (adhesive filler 3) into a supporting member such as a mold 2 '.

According to the fifth method, the same function and effect as those of the fourth method can be obtained. However, in the case of this method, the H-shaped adhesive filler 3 is heated in advance by itself. Since the vulcanized silicone rubber 10 is used, the unvulcanized silicone rubber 9 for integrating the heat-vulcanized silicone rubber 10 and the plate glass 1 can be made thinner, so that the plate glass 1 and the adhesive filler 3 can be integrated. Can be performed in a shorter time.

Next, referring to FIG. 19 to FIG.
An embodiment according to the invention of claim 6 will be described. FIG.
1 shows an example of an assembling structure of an outer wall glass according to claim 1 of the present invention. In FIG. 22, what is indicated by reference numeral 15 is a laminate. The laminated body 15 is composed of a thinly formed heat-cured silicone rubber 10 (a heat-cured silicone rubber layer) and a similarly thinly formed hard material 16 (a hard material layer) such as metal or glass. It consists of multiple layers. Then, the sheet glass 1 is placed on the laminate 15.
Is fixed to the mold 2 'via

One embodiment of a method of constructing the above-mentioned assembly structure will be described with reference to FIGS. First, as shown in FIG. 19, a laminate 1 composed of the unvulcanized silicone rubber 9 (first unvulcanized silicone rubber 9A) and the hard material 16
5 ". The unvulcanized silicone rubber 9 (first unvulcanized silicone rubber 9) constituting the laminate 15" is manufactured.
A) is formed by extrusion or rolling. The laminate 15 ″ is configured such that the lowermost layer and the uppermost layer are layers of the hard material 16. Next, the laminate 15 ″ is put into a vulcanization chamber, and the laminate 1 ″ is placed in a vulcanization chamber.
The first unvulcanized silicone rubber 9A constituting 5 ″ is thermally vulcanized, and as shown in FIG.
A forms a laminate 15 ′ in which the heat-cured silicone rubber 10 is formed. On the other hand, second unvulcanized silicone rubbers 9B, 9B formed in a tape shape by extrusion molding or rolling molding are fixed to the sheet glass 1 and the mold member 2 ', respectively. It is preferable that the surfaces of the plate glass 1 and the mold member 2 ′ to be coated are subjected to a primer coating treatment as required.
Next, as shown in FIG. 21, the laminated body 15 'is interposed between the glass sheet 1 and the mold 2' in correspondence with the second unvulcanized silicone rubbers 9B, 9B.
Then, the mold member 2 ′ is pressure-bonded to the laminate 15 ′ to form the unit 12. Thereafter, the unit 12 is placed in a vulcanization chamber, the second unvulcanized silicone rubber 9B having the plate glass 1 and the laminated body 15 'adhered and fixed thereto, and
The second unvulcanized silicone rubber 9B, to which the mold member 2 'and the laminate 15' are bonded and fixed, is thermally vulcanized to obtain thermally vulcanized silicone rubbers 10,10. As described above, as shown in FIG. 22 and described above, the sheet glass 1 and the mold 2 ′
5 constitutes a fixed mounting structure.

According to the above assembly structure, the glass plate 1 is rigid against the tensile and compressive forces acting in the out-of-plane direction (the direction perpendicular to the glass plate 1) and in the in-plane direction (the glass plate 1). (A forming direction) can be configured to be soft against a shear force acting on the structure. Therefore, for example, even when an external force such as a wind pressure or an earthquake is applied to a building and interlayer displacement occurs, a large stress is not generated in the glass sheet 1.
It is possible to reliably prevent the glass plate 1 from being damaged.

Next, FIG. 25 shows a structure for assembling an outer wall glass for on-site construction, to which the present invention is partially applied.
As shown in FIG. 23, an unvulcanized silicone rubber 9 having a predetermined cross-sectional shape and dimensions is first formed on the outer surface 2a of the mold 2 'by extrusion. Then, as shown in FIG. Unvulcanized silicone rubber 9 is thermally vulcanized in a vulcanization chamber to form a thermally vulcanized silicone rubber 10,
Thereafter, the glass sheet 1 is bonded and fixed to the heat-cured silicone rubber portion 10 of the mold member 2 ′ via the RTV silicone rubber 20. Reference numeral 5 is a backup material. The RTV silicone rubber is a liquid or paste-like vulcanized silicone rubber. In this embodiment, a paste-like material is used.

In the above assembly structure, the sheet glass 1
Is substantially fixed to the mold 2 'by the RTV silicone rubber 20, the actual adhesive strength depends on the strength of the RTV silicone rubber, and the curing speed of the RTV silicone rubber 20 Silicone rubber 1
Since it is slower than 0, the effect of the assembled structure as shown in FIG. 1 cannot be obtained. However, even when the distance between the glass sheet 1 and the support member such as the mold member 2 'is large, most of the thickness of the rubber sheet 10 can be replaced by the heat-cured silicone rubber 10.
, The RTV silicone rubber 20 can be made thinner, thereby shortening the curing time as compared with the conventional assembly structure.

The present invention described above with reference to some embodiments is particularly suitable for application to a sheet glass provided on the outer surface of a building. It can also be applied to attachment to a support member 2 such as a ceramic plate, a stone plate or the like.
