structural sealant glazing
A construction method called the System) construction method has been developed and is already in practical use.

FIGS. 26 and 27 respectively show the above SS
An example of an exterior wall glass assembly structure constructed using the G construction method is shown. In FIG. 26, reference numeral 1 denotes a glass plate forming the outer wall of the building, 2 a back mullion (supporting member) arranged on the indoor side and substantially supporting the plate glass 1, and 3 between the glass plate 1 and the back mullion 2. Adhesive filler 4 is interposed to adhesively fix the glass plate 1 to the back mullion 2, and 4 is the glass plate 1, 1 corresponding to the back mullion 2.
The waterproof sealing material 5 provided at the joint is a backup material that fills the part between the glass plate 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 room temperature vulcanized silicone rubber (structural sealant), 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 building interstory displacement tracking mechanism 6. Components that are the same as those shown in FIG. 26 are given the same reference numerals. In the structure shown in FIG. 27, an inter-story displacement follow-up mechanism 6 that absorbs inter-story displacement when it occurs in the building due to an external force is constructed by the clearance of an adhesive profile (supporting member) 2' attached to the back mullion 2. A plate glass 1 is adhesively fixed to a mold member 2' via an adhesive filler 3.

[0004] According to the exterior wall glass assembly structure assembled by the SSG construction method as described above, it is possible to form a flat exterior that does not show the frame of the sash to the outside of the building. This has effects such as being able to create a design that aims for a mirror effect over the entire exterior of the building.

[0005] The fabrication of the assembly structure using the SSG construction method as described above is carried out by 1) factory fabrication, 2) simple factory fabrication using the floor of the construction site as a temporary factory, or 3) on-site fabrication. There is. Among these, in factory production and simple factory production, the glass plate 1 and the profile 2' are fixed in advance to produce a unit (SSG unit), and the profile 2' of the unit is attached to the back mullion 2. is common. On the other hand, in the case of on-site manufacturing, the back mullion 2 is first built into the building structure, then the glass plate 1 is attached, and the gap between the back mullion 2 and the glass plate 1 is filled with the adhesive filler 3. The adhesive filler 3 is filled with, for example, a manual sealing gun, an air gun using compressed air, or the like.

[0006]

However, the conventional exterior wall glass assembly structure and construction method described above have the following disadvantages or points that should be improved. In other words, in the case of 1) manufactured in a factory, the adhesive filler 3 is applied under ideal conditions using well-equipped equipment.
It is possible to perform curing and inspection, and to manufacture high-quality SSG units; however, i) the adhesive filler 3 uses room-temperature vulcanization silicone sealant as described above, so curing is slow (although it varies depending on temperature and humidity). , it takes about 3 days to 1 month), therefore it occupies a large curing space for a long time, ii) it is not possible to meet large orders due to low productivity, and iii) it is expensive due to reasons i and ii. , etc. were inconvenient. In addition, the simple factory-manufactured products described in 2) are not affected by vibrations or wind pressure during the curing process, and are manufactured at a lower cost than factory-made products because they are manufactured at the construction site. However, i) the curing of the adhesive filler is slow, so a large curing space is required, and ii) differences in temperature and humidity due to seasons and daily weather, or the formation of floors. Condensation is likely to occur on the adhering surface due to the influence of moisture emitted from the concrete, and sand and dust are also likely to adhere, making it difficult to ensure uniform and stable adhesive strength. In addition, while 3) on-site fabrication is the easiest and cheapest to fabricate, it also has the following drawbacks: i) It is difficult to ensure stable adhesive strength due to the influence of weather conditions, and ii) The curing process is affected by wind, vibration, etc. Adverse effects such as damage to the adhesive filling material may occur. iii) Since the joint depth is large, sufficient cleaning, uniform primer application, and reliable filling are difficult, which may lead to poor adhesion or filling.

The present invention has been made in view of the above-mentioned circumstances, and is capable of firmly fixing the plate glass 1 and the support member 2 in a short time, thereby solving the above-mentioned inconveniences. The object of the present invention is to provide a structure for assembling glass on the exterior wall of a building and a method for its construction.

[0020]

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings. The invention according to claim 1 of the present invention, as shown in FIG. The illustrated example is a back mullion)]
The filling adhesive 3 for adhering and fixing is made of heat-vulcanized silicone rubber 10, and this filling adhesive 3 is constructed by extrusion molding.

The filling adhesive 3 made of the heat-vulcanized silicone rubber 10 according to this embodiment is obtained by extruding unvulcanized silicone rubber into a predetermined cross-sectional shape and then heat-vulcanizing it. .

[0022] A method of manufacturing the above-mentioned outer wall glass assembly structure will be explained below. In the figures shown below, the cross-sectional shape of the adhesive molding material 2' is slightly different from that in Figure 27, and the illustration of the backup material and sealing material is omitted except in some figures. .

FIGS. 2 to 4 are process diagrams showing the first method. This first method consists of a plate glass 1 and an adhesive mold 2.
It is suitable for factory production or simple factory production in which the two components are pre-assembled into an integrated unit. First, as shown in FIG. 2, unvulcanized silicone rubber 9 is extruded into a predetermined cross-sectional shape and size using an extrusion molding machine and adhered to the outer surface 2a of the mold material (supporting member) 2', that is, the surface on which the plate glass 1 is to be attached. At this time, it is preferable that the surface to which the unvulcanized silicone rubber is applied on the outer surface 2a of the mold material 2' be subjected to a primer coating treatment, if necessary. Next, as shown in FIG. 3, the plate glass 1 is crimped onto the unvulcanized silicone rubber 9 attached to the mold material 2' to form a unit (SSG unit) 12 in which the glass plate 1 and the mold material 2' are integrated. do. In this case as well, it is advisable to apply a primer treatment to the adhering surface of the plate glass 1, if 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 heat-vulcanized to form a heat-vulcanized silicone rubber 10. Heating in the vulcanization chamber is, for example, 120°C for 3
Preferably, the heating time is 0 minutes or about 15 minutes at 150°C.

According to the above method, since the adhesive filler 3 is provided on the mold material (supporting member) 2' by extrusion molding,
The work of adhering the adhesive filler 3 can be carried out continuously and efficiently, and its thickness etc. can also be freely set. Furthermore, the adhesive filler 3 can be completely cured in an extremely short period of time, and the adhesive strength of the conventional adhesive filler 3 made of room-temperature vulcanized silicone rubber is 7 to 7.
20-60K compared to about 12Kgf/cm2
A significantly large value such as gf/cm2 can be obtained. Further, although this method is suitable for factory production or simple factory production, since the adhesive filler 3 is completely cured in an extremely short period of time, no curing area is required.

Next, FIGS. 5 to 7 are process diagrams showing the second method. This second method also includes the plate glass 1 and the mold material 2'.
It is suitable for factory production or simple factory production in which the two are pre-assembled into an integrated unit. In this second method, as shown in FIG. 5, unvulcanized silicone rubber 9 is first applied to both the mold material 2' and the glass plate 1 by extrusion molding. The unvulcanized silicone rubber 9 may be rolled into a sheet. It is preferable to apply a primer to the surfaces of the glass plate 1 and the mold material 2' to which the unvulcanized silicone rubber 9 is to be applied. Next, as shown in FIG. 6, the sheet glass 1 and the mold material 2', each provided with unvulcanized silicone rubber 9, are pressed together with the attached unvulcanized silicone rubbers 9, and the unit 12 form. Thereafter, as shown in FIG. 7, the unit 12 is put into a vulcanization chamber and thermally vulcanized, thereby converting the unvulcanized silicone rubber 9 into a thermally vulcanized silicone rubber 10. This second method also provides the same effects as those achieved by the first method.

Next, FIGS. 8 to 11 are process diagrams showing the third method. This third method also includes plate glass 1 and mold material 2.
It is suitable for factory production or simple factory production in which the two components are pre-assembled into an integrated unit. In this method, as in the first and second methods described above, first, unvulcanized silicone rubber 9 (
The first unvulcanized silicone rubber 9A) is extruded into a predetermined cross-sectional shape and size using an extrusion molding machine or a rolling molding machine and bonded. If necessary, apply a primer to the surface to be adhered. Next, this first unvulcanized silicone rubber 9
The mold member 2' with A attached thereto is placed in a vulcanization chamber, and the first unvulcanized silicone rubber 9A is made into a heat-vulcanized silicone rubber 10 as shown in FIG. On the other hand, unvulcanized silicone rubber 9 (second unvulcanized silicone rubber 9B) is attached to the portion of the plate glass 1 that is bonded to the heat-vulcanized silicone rubber 10.
is extruded into a predetermined cross-sectional shape and dimensions and adhered (the adhered surface is coated with a primer if necessary), and then, as shown in FIG. A unit 12 is constructed by bonding together the sulfurized silicone rubber 10. Here, the second unvulcanized silicone rubber 9B provided on the side of the glass plate 1 is thinner than the heat-vulcanized silicone rubber 10, and is in the shape of a so-called tape. In the present invention, since the unvulcanized silicone rubber 9 is formed by extrusion molding or rolling molding as described above, the thickness etc. can be easily set as desired. Thereafter, as shown in FIG. 11, the unit 12 is placed in a vulcanization chamber and the second unvulcanized silicone rubber 9B is heat-vulcanized to form a heat-vulcanized silicone rubber 10.

The above method also makes it possible to realize the assembly structure of the outer wall glass as shown in FIG.
Because it hardens in an extremely short time, it can greatly improve work efficiency and eliminate the need for a curing area. In addition, since the adhesive filler 3 (unvulcanized silicone rubber 9) is formed by extrusion molding or rolling, the work of adhering the adhesive filler 3 can be carried out continuously and efficiently, and its thickness can be adjusted freely. For example, it is easy to form it into a tape shape like the second unvulcanized silicone rubber 9B.

Next, FIGS. 12 to 14 are process diagrams showing the fourth method. Note that the assembly structure constructed by this fourth method is different from the structure shown in FIG. Although the structure is similar, it differs from the structure shown in FIG. 1 in that the adhesive filler 3 and the support member are not fixed by adhesive but fixed by locking, as shown in FIG. First, as shown in FIG. 12, unvulcanized silicone rubber 9 is extruded and bonded to a glass plate 1 into a predetermined cross-sectional shape and size using an extrusion molding machine. If necessary, apply a primer to the surface to be adhered. In this case, as shown in the figure, the unvulcanized silicone rubber 9 has a groove 13 with which a support member such as the back mullion 2 or the profile 2' engages, and has an H-shaped cross section. . On the other hand, the support members such as the back mullion 2 and the mold material 2' are formed with grooves 14 that can be engaged with the unvulcanized silicone rubber 9, as shown in FIG. After the unvulcanized silicone rubber 9 is adhesively fixed to the plate glass 1 as described above, it is placed in a vulcanization chamber and heat vulcanized, and the unvulcanized silicone rubber 9 is converted into a heat vulcanized silicone rubber 10 as shown in FIG. shall be. Thereafter, the heat-vulcanized silicone rubber 10 (adhesive filler 3) is fitted into the support member 2, such as the mold 2', thereby attaching the plate glass 1 to the support member.

[0029] In the above method, of course manufacturing is possible in a factory, but
Since the plate glass 1 and the supporting member 2 are substantially fixed by fitting, it is also possible to construct the molded material 2' on the site in advance. Also, when forming the adhesive filler 3 into an H-shape as described above, this can be done extremely easily since the unvulcanized silicone rubber 9 is formed by extrusion molding. Furthermore, in the above assembly structure, only the glass plate 1 and the adhesive filler 3 are fixed by adhesive, so adhesive reliability is taken into consideration when fixing the adhesive filler 3 and supporting members such as the molding material 2'. There is no need to do so, and the labor and effort required for testing the adhesive strength can be reduced accordingly. In addition, in the above structure, the adhesive filler 3 and the mold material 2'
When fixing to a support member such as the above, the locking structure may be used as described above, and then both may be bonded together.

Next, FIGS. 15 to 18 show a fifth method. In this fifth method, the adhesive filler 3 is fitted into the support member 2, as in the fourth method. First, as shown in FIG. 15, unvulcanized silicone rubber 9 is extruded into an H shape. Then,
The unvulcanized silicone rubber 9 is heat-vulcanized in a vulcanization chamber to form a heat-vulcanized silicone rubber 10 as shown in FIG. On the other hand, a tape-shaped unvulcanized silicone rubber 9 extruded or rolled is fixed to the side of the plate glass 1 (the adhering surface is coated with a primer if necessary), and then as shown in FIG.
As shown in 7, the heat-vulcanized silicone rubber 10 is pressed and fixed onto the tape-shaped unvulcanized silicone rubber 9. after that,
The plate glass 1 to which the unvulcanized silicone rubber 9 and the heat-vulcanized silicone rubber 10 are fixed is placed in a vulcanization chamber, and the unvulcanized silicone rubber 9 is bonded to the heat-vulcanized silicone rubber 1.
Set to 0. Thereafter, as shown in FIG. 18, the heat-vulcanized silicone rubber 10 (adhesive filler 3) is fitted into a support member such as a mold 2', thereby attaching the plate glass 1 to the support member.

According to the fifth method, the same effects as the fourth method described above can be obtained, but in the case of this method, the H-shaped adhesive filler 3 itself is heated in advance. Since the sulfurized silicone rubber 10 is used, the unvulcanized silicone rubber 9 that integrates the heat-vulcanized silicone rubber 10 and the plate glass 1 can be made thin, and therefore the plate glass 1 and the adhesive filler 3 can be integrated. can be done in a shorter time.

Next, FIG. 22 shows an example of an assembly structure for outer wall glass according to claim 3 of the present invention. Figure 2
In No. 2, the reference numeral 15 is a laminate. This laminate 15 consists of thinly formed heat-vulcanized silicone rubber 10 (heat-vulcanized silicone rubber layer) and thinly formed hard material 16 such as metal or glass (hard material layer) alternately. It is made up of multiple layers. The plate glass 1 is fixed to the mold material 2' via the laminate 15.

An embodiment of the method for constructing the assembly structure described above will be described with reference to FIGS. 19 to 21. First, as shown in FIG. 19, a laminate 1 made of unvulcanized silicone rubber 9 (first unvulcanized silicone rubber 9A) and the hard material 16
5". The unvulcanized silicone rubber 9 (first unvulcanized silicone rubber 9A) constituting this laminate 15"
) is formed by extrusion molding or rolling molding. Further, this laminate 15'' is configured such that the bottom layer and the top layer thereof are layers of hard material 16.Next, the laminate 15'' is placed in a vulcanization chamber, and the laminate 15'' is placed in a vulcanization chamber.
The first unvulcanized silicone rubber 9A constituting the first unvulcanized silicone rubber 9A is heat-vulcanized to form a laminate 15' in which the first unvulcanized silicone rubber 9A is made into a heat-vulcanized silicone rubber 10 as shown in FIG. On the other hand, the plate glass 1 and the mold material 2' each have a second tape formed by extrusion molding or rolling molding.
unvulcanized silicone rubbers 9B and 9B are fixed to each other. It is preferable that the surfaces of the glass plate 1 and the mold material 2' be coated with a primer, if necessary. Next, as shown in FIG. 21, the laminate 15' is interposed between the plate glass 1 and the mold material 2' in correspondence with the second unvulcanized silicone rubber 9B, 9B, and the plate glass 1 is
and the mold material 2' are pressed together to the laminate 15' to form the unit 12. Thereafter, the unit 12 is placed in a vulcanization chamber, and the second unvulcanized silicone rubber 9B is bonded and fixed to the plate glass 1 and the laminate 15', and
The second unvulcanized silicone rubber 9B to which the mold material 2' and the laminate 15' are adhesively fixed is heat-vulcanized to form heat-vulcanized silicone rubbers 10 and 10. As shown in FIG. 22 and described above, the plate glass 1 and the mold material 2' can be assembled into the laminate 1 as shown in FIG.
5 constitutes a fixed assembly structure.

According to the above assembly structure, the glass plate 1 is rigid against tensile and compressive forces acting in an out-of-plane direction (a direction perpendicular to the glass plate 1), and is rigid against tensile and compressive forces acting on the glass plate 1 in an in-plane direction (a direction perpendicular to the glass plate 1). It is possible to construct a structure that is flexible against shear forces acting in the direction of formation of the material. Therefore, even if an external force such as wind pressure or an earthquake is applied to a building and displacement occurs between the layers, large stress will not be generated on the glass plate 1.
Damage to the glass plate 1 can be reliably prevented.

Next, FIG. 25 shows a structure for assembling exterior wall glass constructed on-site by partially applying the present invention. In the assembly structure of this exterior wall plate glass, first, as shown in FIG. 23, unvulcanized silicone rubber 9 having a predetermined cross-sectional shape and dimensions is extruded on the outer surface 2a of the mold material 2', and then the unvulcanized silicone rubber 9 is formed as shown in FIG. Unvulcanized silicone rubber 9 is heat-vulcanized in a vulcanization chamber to form heat-vulcanized silicone rubber 10;
Thereafter, the plate glass 1 is adhesively fixed to the heat-vulcanized silicone rubber 10 portion of the mold 2' via the RTV silicone rubber 20. Reference numeral 5 is a backup material. RTV silicone rubber is a room-temperature vulcanizable silicone rubber in liquid or paste form. In this embodiment, a paste-like material is used.

In the above assembly structure, the plate glass 1
is substantially fixed to the mold material 2' by the RTV silicone rubber 20, so the actual adhesive strength depends on the strength of this RTV silicone rubber, and the curing speed of this RTV silicone rubber 20 also depends on the heat vulcanization rate. silicone rubber 1
Since this is slower than 0, it is not as effective as the assembly structure shown in FIG. However, even when the distance between the plate glass 1 and the support member such as the mold 2' is large, most of the thickness is covered by the heat-vulcanized silicone rubber 10.
By forming the RTV silicone rubber 20, it is possible to make the RTV silicone rubber 20 thinner, thereby shortening the curing time compared to the conventional assembly structure.

The present invention, which has been described above based on several embodiments, is particularly suitable for application to plate glass provided on the exterior of buildings, but is also suitable for use with exterior wall components other than plate glass, such as large tiles. , a ceramic plate, a stone plate, etc. can also be applied to attachment to the support member 2.

[0038]

As explained above, according to the exterior wall glass assembly structure according to claim 1, by using heat-vulcanized silicone rubber as the adhesive filler, the plate glass and the supporting member can be bonded extremely firmly. This not only makes it possible to realize a highly reliable exterior wall glass assembly structure, but also significantly reduces the curing time of the adhesive filler, greatly improving work efficiency, and also allows for a large curing area. It is possible to manufacture this without the need for it and without being affected by environmental changes such as temperature and humidity, making it possible to realize a high-quality assembly structure efficiently and at low cost. Furthermore, since the adhesive filler is formed by extrusion molding or rolling, the adhesive filler can be applied continuously and efficiently, and its shape, thickness, etc. can be freely set. There are advantages.

[0039] According to the exterior wall glass assembly structure according to claim 2, there is no need to consider the adhesion reliability when fixing the adhesive filler and the supporting member, and the fixing reliability between the plate glass and the supporting member is improved. becomes more sexual. Also,
Since the adhesive filler is formed by extrusion molding, the shape of the adhesive filler can be easily formed into a shape that can be engaged with the support member. Furthermore, since the supporting member and the adhesive filler are fixed and locked, it is possible to easily perform construction on site even though the adhesive filler is made of heat-vulcanized silicone rubber.

[0040] Furthermore, according to the assembly structure of the exterior wall glass according to claim 3, the sheet glass is rigid against tensile and compressive forces acting in an out-of-plane direction, and is rigid against shear forces acting in an in-plane direction. It is possible to construct a flexible structure. Therefore, even if, for example, an external force such as wind pressure or an earthquake is applied to a building and displacement occurs between the layers, no large stress is generated on the glass plate, and breakage of the glass plate can be reliably prevented. Furthermore, the same effects as the invention according to claim 1 can be obtained, such as improving the adhesive strength between the plate glass and the supporting member and shortening the effective time.

[0041] The inventions according to claims 4 and 5 respectively correspond to the invention according to claim 1, the inventions according to claims 6 and 7 correspond to the invention according to claim 2, and the invention according to claim 8 corresponds to the invention according to claim 2. Each of the inventions described in item 3 can be efficiently realized.
