BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings. A structure of a glass wall unit in the present embodiment, as shown in FIGS. The channel-shaped glass 1 and 1 are adhered with a standard silicone sealing material 10 to manufacture a substantially hollow box-shaped glass wall unit 20, and a plurality of glass wall units 20 are stood upright and arranged side by side in a lateral direction. A narrow vertically long standing surface 21 of 20 is directed to the outside of a building 30 such as a building.

As shown in FIGS. 2 and 3, the pair of grooved glasses 1 and 1 are arranged so as to face each other so as to form a hollow, and one or more opaque plates 2 are incorporated in the longitudinal direction, and a cross section is formed at both ends of the opening. Plugs 3 each having a substantially U-shape and a substantially rectangular shape are selectively and arbitrarily mounted via cushioning rubbers. As shown in FIG. 3, the opaque plate 2 is formed to have the same length as that of the pair of grooved glasses 1.1, and seals inside the pair of grooved glasses 1.1 before and after, or inside and behind. It is selectively and arbitrarily attached via. Further, as shown in FIG. 3, a pair of rod holes 4 are formed in each plug 3 at intervals, and each rod hole 4 has a reinforcing rod 5 penetrating the inside of the pair of channel glass 1. Is screwed on via a double nut or a spring nut. A rod-shaped hanger 6 is detachably attached to the center of each plug 3, and the hanger 6 is attached to the building 30.
Will be hung from the opening that will be installed.

As shown in FIGS. 3 and 5 (a), each channel glass 1 is bent and formed into a long length (for example, about 3 to 5 m) having a substantially U-shaped cross section, and its narrow and short bent wall 7 is formed. A narrow vertically long standing surface 21, in other words, a part of the exposed front surface or back surface, and a wide and long non-bending wall 8 is a side surface facing the lateral direction of the building 30. The curved wall 7 of the channel glass 1 has a surface formed on the pattern surface of a mold pattern as needed,
The free end is rounded and chamfered to form the ear 9, and the fixed silicone sealing material 10 is bonded to the rounded ear 9 (see FIG. 5A).

The standard silicone sealing material 10 is shown in FIG.
As shown in FIG. 5, the strip-shaped strip is formed into a long and narrow shape, and is wound around a reel together with release paper, and is deformed when an appropriate external force is applied. This standard silicone sealing material 10 is
(Uncured) addition reaction type adhesive silicone material, or
Consists of (uncured) condensation reaction type adhesive silicone material.
The addition reaction type adhesive silicone material is cured at room temperature by adding an excessive amount of a curing reaction catalyst. In contrast,
The condensation reaction type adhesive silicone material is cured by moisture in the air. These standard silicone sealing materials 10 are
Sealing with oxime integrated Shin-Etsu Silicone Sealant Compared with general silicone sealing materials such as SA-45 (manufactured by Shin-Etsu Polymer Co., Ltd.), the adhesive strength is improved by 2 to 5 times, and the work of attaching masking tape The feature is that it is not necessary. Also, since the adhesion reaction is fast, there is no need to secure a curing space for a long period of time,
The rationalization of production can be expected and the cost can be reduced significantly.

The addition reaction type adhesive silicone material is
Organohydrogenpolysiloxane and platinum catalyst
Reactions with Addition Reaction Curing Catalysts
It cures by crosslinking. As the main component, the hardness after curing is
20-80 ° organopolysiloxane compound
This organopolysiloxane has an average unit formula R _a
SiO_{(4-a) / 2}Indicated by. In the formula, a is 1.90 to 2.
05, R is an alkyl group such as methyl group, ethyl group, propyl group, etc.
Kill group; cycloallyl group such as cyclohexyl group; phenyl
Aryl group such as vinyl group and tolyl group; vinyl group, allyl group, etc.
Alkenyl groups; or hydrogen bonded to these carbon atoms
Part or all of the atoms may be halogen atoms, amino groups,
A chloromeme substituted with a silane group, a carboxyl group, a cyano group, etc.
Same or different non-substituted or substituted monovalent hydrocarbon such as chill group
Elementary groups, preferably 80% mol or more is a methyl group, 0.1
To 0.5 mol% vinyl group-containing organopolysiloxa
And the viscosity at 25 ° C is 100 cSt or more,
It is better to use a base material of 1000 cSt or more.
The end of the organopolysiloxane is silanol.
Those blocked with a group, a methyl group or a vinyl group are preferable,
Those blocked with a vinyl group are particularly preferable.

The addition reaction type adhesive silicone material is 100 parts by weight of the alkenyl group-containing organopolysiloxane as described above, 1.5 to 10 times the equivalent amount of the organohydrogenpolysiloxane as the former, and vinyl as the adhesion improver. A room temperature-curable adhesive silicone rubber composition containing 3 to 10 parts by weight of alkoxysilane having a group and 20 to 500 ppm of chloroplatinic acid as a catalyst in terms of platinum. When the amount of the organohydrogenopolysiloxane is less than 1.5 times the equivalent of the amount of the alkenyl group-containing organopolysiloxane, the adhesive strength of the rubber composition according to the present invention becomes insufficient and exceeds 10 times the equivalent. Although the adhesive strength is increased, the silicone rubber itself becomes brittle. Also,
When the amount of the alkoxysilane having a vinyl group is less than 3 parts by weight, the water resistance is not sufficient, and conversely, when it exceeds 10 parts by weight, the effect is not improved. Further, when the content of chloroplatinic acid in the catalyst is less than 20 ppm in terms of platinum, the curing reaction rate at room temperature is insufficient, and when it exceeds 500 ppm, the curing reaction rate at room temperature is too large and the handling is difficult, and A strong acid catalyst such as chloroplatinic acid will cause depolymerization.

The standard silicone sealant 10 is generally a mixture of the above organopolysiloxane and the like with a silica-based filler. Examples of the silica-based filler include fumed silica, wet silica, hydrophobic silica and quartz powder. A typical example is diatomaceous earth. The particle size of the silica-based filler is preferably 50 μm or less, and the addition amount thereof is preferably in the range of 20 to 200 parts by weight with respect to 100 parts by weight of the organopolysiloxane. The composition may further contain, as a silica dispersant, a silane containing an alkoxy group, a silanol group or the like, a heat resistance improver, an inorganic pigment or the like. If the particle size of the silica filler exceeds 50 μm, it is difficult to obtain sufficient dispersibility, and if the amount added is less than 20 parts by weight, it is difficult to obtain a sufficient reinforcing effect, and conversely 200 parts by weight. When it exceeds, the original performance of the rubber composition is likely to be lost.

In the present invention, as the Si--H crosslinking agent,
It is preferable to use an organohydrogenpolysiloxane having at least two hydrogen atoms bonded to silicon atoms in the molecule, and an excess amount of a platinum catalyst for curing reaction (platinum chloroplatinate, chloroplatinic acid and alcohol, acetaldehyde). It is preferable to add a complex salt with and the like (1.5 to 50 times the usual amount) and an appropriate amount of the reaction inhibitor. The amount of the Si-H crosslinking agent added to the organohydrogenpolysiloxane containing the alkenyl group of the organohydrogenpolysiloxane is ≡ relative to the vinyl group (alkenyl group) contained therein.
SiH / ≡Si (CH = CH ₂ ) may be in a range that gives 1.2 to 5.0 (molar ratio). This is because if it is less than 1.2, the adhesive strength is insufficient, and if it exceeds 5.0, the adhesive strength increases, but the silicone rubber itself becomes brittle and causes problems in use. is there. As the adhesion improver added to the silicone rubber, a silane coupling agent, for example, an epoxy silane, a vinyl silane or a titanate coupling agent, an aluminum coupling agent, or a coupling agent obtained by blending these is added. good.

Further, since the addition reaction type adhesive silicone material has an excess amount of the curing reaction catalyst added therein, it can be cured and adhered at room temperature, but it cannot be stored for a long time as it is. is there. Therefore, when storing it for a long period of time, keep it at a low temperature of 5 ° C or lower, or enclose it in a completely sealed low-temperature container and make it saturated with the vapor of acetylene alcohol or its derivative that is an inhibitor of the addition reaction. Just do it. The addition reaction type adhesive silicone-based material can be cured and bonded instantly at high temperature, but since it can be cured and bonded even at room temperature, there is substantially no problem in adhesiveness.

On the other hand, the condensation reaction type adhesive silicone material is cured by a condensation reaction by dealcoholization and acetone removal in which organopolysiloxane having hydroxyl groups at both ends of the molecular chain is added with a crosslinking agent, titanium system catalyst and tin system catalyst. Some of them are cured by a condensation reaction with a deoxime, and among these, one of a deoxime is preferable. In the material of and, the organopolysiloxane used as the main raw material has the same average unit formula as the organopolysiloxane described in relation to the material having a hydroxyl group which is a reactive functional group at both ends of the molecular chain, It is preferable that 80 mol% or more of R is a methyl group.

The average degree of polymerization of this organopolysiloxane is 3,000 or more, and particularly 5,000 to 10,000.
Is preferred. In this condensation reaction type adhesive silicone material, by using an organopolysiloxane having an average degree of polymerization of 3,000 or more, the filler added for shaping the condensation reaction type adhesive silicone material is used. The amount of the agent can be reduced, and a cured product that does not impair rubber elasticity can be obtained.
In addition, the amount of low-molecular-weight organopolysiloxane remaining is reduced, so that the uncrosslinked material is less likely to be damaged before curing, and the adherend or the like can be prevented from being contaminated.

As the cross-linking agent to be blended with the above materials and / or materials, an organosilane having 3 to 4 alkoxy groups directly bonded to a silicon atom in a molecule or a mixture thereof, or a siloxane oligomer having an alkoxy group is used. To be done. Specifically, tetraethoxysilane, tetra-n-propoxysilane, methyltrimethoxysilane, methyltriethoxysilane, vinyltrimethoxysilane, phenyltrimethoxysilane, phenyltriethoxysilane, 3,3,3-trifluoropropyl Examples thereof include triethoxysilane, 3,4-epoxybutyltrimethoxysilane, 3-glycidoxypropyltrimethoxysilane, 3- (methacryloxypropyl) trimethoxysilane, and ethylpolysilicate, but especially methyltrimethoxysilane, Methyltriethoxysilane, phenyltrimethoxysilane and phenyltriethoxysilane are preferred.

Further, an organosilane having two ketoxime groups bonded to a silicon atom in one molecule, such as dimethylbis (methylethylketoxime) silane and methylvinylbis (methylethylketoxime) silane, is used in combination for adjusting the crosslink density. You may. However, it is desirable not to exceed 20% by weight with respect to the cross-linking agent having 3 or more ketoxime groups in one molecule. This is because if it exceeds 20%, the physical properties are deteriorated. The amount of the cross-linking agent to be added is 50 to 50 with respect to the hydroxyl group of the above organopolysiloxane.
The amount is 600 equivalents, and particularly preferably 200 to 500 equivalents. This is because if the amount is less than 50 equivalents, the moisture-proof storage property is deteriorated, and if the amount exceeds 600 equivalents, the original curing reaction is hindered, and conversely it becomes difficult to cure.

In the above materials, a titanium-based catalyst and a tin-based catalyst are blended in order to appropriately control the curing rate of the organopolysiloxane by condensation crosslinking. By thus using two kinds of catalysts in combination, the curing speed in the deep part of the organopolysiloxane can be increased. Considering the curing speed and curing stability, titanium-based
R) ₄ (wherein R represents an ethyl, propyl, butyl, amyl, or hexyl group) is exemplified, and the compounding amount thereof is 0.1 to 1% by weight based on 100 parts by weight of the organopolysiloxane. 0 parts by weight. If it is less than 0.1 part by weight, the curing is incomplete and the moisture-proof storage property is deteriorated.
This is because if the amount is more than parts by weight, the moisture-proof storage property is reduced. Further, tin-based catalysts, considering the curing rate, are exemplified by organic acid salts such as tin octoate and tin octenoate, and alkyltin compounds such as butyltin acetate, dibutyltin laurate and dibutyltin oleate. 0.01 to 100 parts by weight of polysiloxane
0.1 parts by weight. This is because if it is less than 0.01 parts by weight, the curing will be incomplete, and conversely if it exceeds 0.1 parts by weight, the moisture-proof storage property will be deteriorated.

The catalyst used for the above materials is
Organic acid salts such as tin octoate and tin octenoate, alkyltin compounds such as dibutyltin dilaurate and dibutyltin oleate, Ti (OR) ₄ (R is ethyl, propyl,
Examples thereof include organic titanium compounds represented by butyl, amyl, hexyl and other alkyl groups), and amines such as dimethylhydroxylamine and ethylhydroxylamine. These are not limited to one type, and two or more types may be combined. The amount of the catalyst blended is 0.005 to 0. 0, based on 100 parts by weight of the organopolysiloxane.
It is 1 part by weight, and particularly preferably 0.01 to 0.05 part by weight. This is because if it is less than 0.005 parts by weight, internal curing becomes incomplete, and if it exceeds 0.1 parts by weight, moisture-proof storability decreases and the curing speed becomes too fast, resulting in a decrease in workability. Because it does. When an amine-based silane coupling agent such as γ-aminopropyltriethoxysilane is used as an adhesion aid to be described later,
Since these also have a catalytic effect, it is not necessary to add the above catalyst, or even a very small amount may be added.

In the materials (1) to (3), a filler is added to the main component organopolysiloxane in order to impart strength and shapeability. As the filler, calcium carbonate, titanium oxide, or the like can be used, but a silica-based filler is preferable from the viewpoint of heat resistance and reinforcing effect. Examples of the silica-based filler include fumed silica, fumed silica, wet silica, hydrophobic silica, quartz powder, and diatomaceous earth, and fumed silica having a particle size of 50 μm or less is particularly preferable. This is because if it is larger than 50 μm, the reinforcing effect decreases.

The amount of the filler to be blended is 20 to 200 for the above materials based on 100 parts by weight of the organopolysiloxane.
It is considered to be part by weight. It is preferable to use 5 to 50 parts by weight, especially 10 to 35 parts by weight for the material of No. This is because when the compounding amount is less than 5 parts by weight, sufficient strength and shapeability cannot be obtained, and when the compounding amount exceeds 50 parts by weight, the condensation reaction type adhesive silicone rubber material becomes hard. The workability is reduced. In addition, these silica-based fillers may be surface-treated in advance with chlorosilane, silazane or the like in order to improve dispersibility. Further, in order to enhance the dispersibility of the filler and impart a stable strength to the uncured adhesive silicone rubber-based material, a wetting agent may be added to each of the materials.

As the wetting agent, a dimethyl silicone oil having a hydroxyl group at the terminal of the molecular chain and a low degree of polymerization of about 5 to 20, diphenylsilanediol, an alkoxy group such as hexamethyldisilazane, and a silanol group are included. Silane and low molecular weight siloxane. The amount of the wetting agent blended is preferably 0.5 to 10 parts by weight with respect to 100 parts by weight of the organopolysiloxane. This is because if it is less than 0.5 parts by weight, the dispersibility is not improved, and if it exceeds 10 parts by weight, the strength of the silicone rubber material is lowered.

In addition to the above components, an adhesion aid, a non-reinforcing filler, an inorganic pigment, an ultraviolet absorber, an antifungal agent and the like can be appropriately added to the above materials, particularly the above and / or materials. Adhesion aids include, for example, γ-aminopropyltriethoxysilane, vinyltrichlorosilane, vinyltriethoxysilane, γ-glycidoxypropyltrimethoxysilane, and other silane coupling agents, isopropyltriisostearoyl titanate, and isopropyltri ( N
-Titanate coupling agents such as -amidoethyl-aminoethyl) titanate and tetraoctylbis [(ditridecyl) phosphite] titanate are included, and the amount thereof is preferably 2 parts by weight or less based on 100 parts by weight of organopolysiloxane. It is also possible to use a sponge rubber to which a foaming agent such as azobisisobutyronitrile is added.

The uncured adhesive silicone rubber material can be obtained by uniformly mixing predetermined amounts of the above components in a dry atmosphere and molding the mixture into a given shape. When the obtained uncured adhesive silicone rubber-based material is exposed to the air at room temperature, the moisture in the air causes a condensation crosslinking reaction to proceed and cure into a rubber elastic body. Further, the hydrolyzable functional group bonded to the silicon atom in the cross-linking agent is hydrolyzed to generate a silanol group, and a hydrogen bond is formed between the silanol group and an inorganic material such as glass, tile, or metal.
Good adhesion is obtained after curing.

In order to shape the uncured adhesive silicone rubber material into a certain shape, it may be formed into a predetermined shape such as a sheet or a string by a generally known method. For example, after blending and kneading the above components using a two-roll, pressure kneader, Banbury mixer, etc., to obtain a silicone rubber composition,
It can be formed into a sheet with two rolls or a calendar roll, or can be cut with a guillotine cutter or slitter to form a string or strip with a desired width and thickness, or a string with an irregular cross section by an extruder. It can be a molded body.

The plasticity of these uncured adhesive silicone rubber materials is preferably in the range of 50 to 500. This is because when the plasticity is less than 50, when the regular silicone sealing material 10 is sandwiched between the ears 9 of the pair of upper and lower groove-shaped glasses 1.1, the regular silicone sealing material 10 is more than necessary. Because it collapses and does not function. On the other hand, when the plasticity is more than 500, when the fixed silicone sealing material 10 is sandwiched between the ears 9 of the pair of upper and lower grooved glasses 1.1, the fixed silicone sealing material 10 is hard and crushed. This is because it becomes difficult and the contact area of the ear 9 is reduced. The plasticity of the uncured adhesive silicone rubber-based material may be measured by a test method for uncured and cured silicone rubber [see JIS K 6249 et seq.].

When the obtained regular uncured adhesive silicone rubber material is stored for a long period of time, it is difficult to store the above materials as they are, but if they are stored at a low temperature of 5 ° C. or lower, they should be stored for a long period of time. You can At a high temperature, it cures and adheres instantly, but at room temperature of 5 ° C. or higher, practically no problem occurs in adhesiveness. In addition, it is advisable to completely seal the above materials in a moisture-proof package in which aluminum foil or the like is laminated so that the curing reaction does not proceed with moisture in the atmosphere.

Examples of the moisture-proof packaging include plastic films having a low moisture permeability, such as a single or composite film of OPP or PVDC, aluminum vapor-deposited PET, or a composite product of aluminum foil and plastic film. Among these, a laminated film of an aluminum foil and a plastic film, which has substantially zero moisture permeability, small temperature dependency, and excellent durability, is preferable. As for this laminated film, in order to prevent occurrence of pinholes in the aluminum foil due to bending, it is preferable that two laminated films are laminated and made into a bag by a method such as heat welding. If necessary, a hygroscopic agent such as calcium oxide, synthetic zeolite, or silica gel may be enclosed in the package, or nitrogen substitution, vacuum packaging, or the like may be performed.

In the above structure, the glass wall unit 20
In the case of manufacturing, first, the plurality of grooved glasses 1 are each cut into a predetermined size to have a predetermined length, and one grooved glass 1 is horizontally and upwardly arranged on the workbench and cleaned.
The opaque plate 2 is attached to the inside rear of the one grooved glass 1 (rightward in FIG. 5A) by a seal in a horizontally long state.
(See FIG. 5 (a)). At this time, the one channel glass 1 may be bent due to its own weight, and therefore the length of the work table should be carefully considered. Further, at the time of sealing, it is preferable to perform a spatula finish so that the seal does not remain on the ear portion 9 of the one grooved glass 1.
In this way, when the opaque plate 2 is attached to the inside of the one grooved glass 1, the frozen fixed silicone sealant 10 is formed.
Is thawed, and the fixed-shape silicone sealing material 10 is placed in the longitudinal direction of each ear portion of one grooved glass 1 and strongly pressed and adhered from above with a roller or the like (see FIG. 5B).

Next, the plugs 3 are fitted into the both ends of the opening of the one grooved glass 1 while adjusting each with a cushioning rubber, and a pair of rods 5 are inserted between the pair of plugs 3 via a double nut or a spring nut. Shaft (see Fig. 5 (c)),
The other grooved glass 1 is strongly overlapped from above the one grooved glass 1 and adhered by the fixed-shape silicone sealing material 10, and the fixed shape between the ears 9 and 9 of the pair of pressure-bonded grooved glasses 1 and 1 is pressed. The dimensional accuracy is adjusted so that the silicone sealing material 10 is sufficiently adhered (see FIG. 5D). When stacking the other channel glass 1, it is convenient to use a suction cup for a template. When the pair of grooved glasses 1.1 is bent, a liner is sandwiched between the center portions of the pair of grooved glasses 1.1 to adjust the joints.

Then, the fixed-shape silicone sealing material 10
It is confirmed that a certain amount of space between the ears 9 and 9 has been crushed and adhered sufficiently, and the shaped silicone sealing material 10 protruding from between the ears 9 and 9 is flattened from the outside by a roller indicated by an arrow (Fig. 5 (e )), The bag-shaped glass wall unit 20 can be manufactured by hardening the fixed-shape silicone sealing material 10 while sandwiching the pair of grooved glasses 1 and 1 in a jig (not shown) while preventing the deviation. it can.

When a plurality of glass wall units 20 are manufactured in the factory and stored in the rack in this way, the plurality of glass wall units 20 are collectively carried from the factory to the construction site of the building 30. Then, the hangers 6 are inserted into the plugs 3 of the plurality of glass wall units 20, respectively, and the hanger 6 is hung on the frame of the opening of the building 30 in a state where each glass wall unit 20 is erected to form the grooved glass. The self-weight of the glass wall units 20 is regulated, and the plurality of glass wall units 20 of the opening portions of the building 30 are directed toward the outside of the building 30 with the narrow vertical standing surface 21 of each glass wall unit 20 as the front. After arranging them side by side in a curtain manner in the lateral direction, and adhering a plurality of adjacent glass wall units 20, the outer wall of the building 30 can be transparently constructed and a large amount of light can be used for production ( (See Figure 1).

According to the above construction, the glass wall unit 20
Since the narrow vertical standing surface 21 is used as the front surface and is directed in the outward direction of the building 30, in other words, in the direction substantially orthogonal to the arrangement direction of the plurality of glass wall units 20, for example, the glass wall unit 20 is Even with a long length, it is possible to secure sufficient rigidity in the inward and outward directions of the building 30, and thereby obtain sufficient wind pressure strength (for example, it is possible to withstand a wind pressure strength of 500 kgf / m ² ). Further, even when a large number of them are used, since they are actually excellent in strength, they do not require any seismic reinforcement, and it is possible to easily reduce the number of parts and simplify the work. Further, even if the installation area is large, the number of the glass wall units 20 arranged is not particularly limited, so that continuous arrangement and free design can be greatly expected.

Further, since the outer wall of the building 30 is constructed by utilizing the short front surface of the glass wall unit 20, it is easy to obtain a beautiful and diverse design woven by a flat wall and a curved wall, and to reflect external light. The lighting can be changed in various ways, and new architectural expressions can be easily created. For example, the contradictory elements of a complicated but elegant curved wall lower structure and a linear upper structure may be replaced by the glass wall unit 2.
It can be fused with zero characteristics to complete a bold and delicate design. When the concrete wall surface is covered with the glass wall unit 20, it is possible to develop various design characteristics such as a change in color tone and texture due to matching with other building materials.

Further, since the glass wall unit 20 has a hollow cylindrical shape that cannot be put into the interior, the liquid silicone sealant cannot be pressed because it cannot be pressed at the time of manufacturing, but it is a fixed shape that is easy to handle. Since the silicone sealant 10 is used, the hollow box-shaped glass wall unit 20 can be manufactured very easily. Further, the plasticity of the fixed-shape silicone sealing material 10 is 50 to
Since it is in the range of 500, it becomes possible to prevent excessive subsidence and dimensional deviation and properly bond the pair of grooved glasses 1.1. Furthermore, since each glass wall unit 20 is suspended to prevent the weight of each channel glass 1 from being applied by its own weight, the glass wall unit 20 does not break due to an earthquake or the like. Furthermore, since a pair of grooved glasses 1.1 are used in combination facing each other, in addition to wind pressure resistance,
It is possible to greatly improve heat insulation and sound insulation.

In the above embodiment, the opaque plate 2, the plug 3, the buffer rubber, the rod 5, the hanger 6 and the like are used, but the present invention is not limited to this.
If substantially the same effect can be expected, the constituent elements can be appropriately increased or decreased. For example, the opaque plate 2 and the like can be omitted depending on the need and cost. Further, the structure of the glass wall unit 20 can be used as a curved wall of R type, S type, or the like.

[0039]

As described above, according to the present invention, the wind pressure strength and the continuity can be excellently used regardless of the area, and a beautiful design woven by a flat wall and a curved wall can be obtained. In addition, even when a large number is used, there is an effect that the reinforcing tool is not necessarily required.
