[0003]

In the sealant construction method in the construction that must be performed under such external conditions, the formwork construction method is a wet construction method in which the sealant is filled, so that it takes time to cure and the humidity is high. ， Construction may not be possible in winter due to temperature conditions, and the sealant joints may contaminate the wall surface due to dust pollution or secondary pollution. In addition, a gasket construction method in which a fixed gasket is fitted has also been attempted, but the airtightness and watertightness of the gasket depend on the compression set characteristics of the material,
Performance deterioration is expected due to many factors such as weather resistance, heat resistance, ozone resistance, and temperature dependence of hardness. Basically, if there is no watertight function, the isobaric construction method and drainage construction method of the invading water are compelled. There is a drawback that it becomes high, and it is not sufficiently satisfied in terms of airtightness and watertightness. Especially, the fixed gasket is easily displaced due to wind pressure, vibration, and thermal stress, and it easily sticks out. There are many problems such as sashes and absorption of glass plate dimensional tolerances. The present invention eliminates these drawbacks of the conventional sealant construction method and gasket construction method, greatly improves the workability by the dry construction method, and can be constructed without being affected by the weather even in the relatively low temperature and low humidity winter season. It is possible to optimize the maintenance of airtightness and watertightness of joints,
It is an object of the present invention to provide a wall-to-wall seal structure and its driving seal construction method in a simple and inexpensive form, which can reduce the construction period and man-hours, can prevent dust pollution, and can also contribute to prevention of outer wall pollution.

EXAMPLE An example of the present invention will be described with reference to an example of a high-rise building wall in FIGS. 1 to 3. Hard rubber (hardness about 60 degrees), soft rubber or foamed rubber of silicone rubber whose elasticity, strength and hardness can be appropriately selected. Of the elastic gasket 1 made of a foam material or the like, and other similar elastic bodies are integrally bonded to both sides of a reaction type adhesive layer 2 containing a platinum catalyst as a main component and containing a Si—H crosslinking agent. Protective film 5 on 2 if necessary

The reactive adhesive layer 2 is one that undergoes a curing reaction at room temperature or a temperature above room temperature, preferably at a temperature of 10 ° C. to 40 ° C. An adhesive that reacts at room temperature and exerts adhesive strength, and an elastic gasket and glass to be adhered,
It shows an effective adhesive strength with aluminum, SUS, etc. It is stored in a cold place (5 ° C or less) and pasted on site during construction. For example, as the reactive adhesive layer 2, -Si-C is used.
H = CH ₂ Vinyl is an addition reaction type composed mainly of a Si-H crosslinking agent, a reinforcing agent such as silica, quartz powder, and alumina, and additives such as an adhesion improver, a heat-resistant material, and a flow regulator. The material may be formed on the side surface of the silicone rubber elastic gasket 1 by coating, impregnation, extrusion, or the like, or may be attached at the time of construction. In this case, since the addition reaction type adhesive layer has a suitable curing reaction catalyst added therein, it can be cured and adhered at room temperature, but for long-term storage, it should be kept at a low temperature of 5 ° C or lower or a completely sealed container. In addition, by coexisting with an addition reaction inhibitor (acetylene alcohols, etc.), long-term storage becomes possible. The addition reaction type adhesive layer can be cured and bonded instantly at a high temperature, but at a temperature of 10 ° C. or higher, practical adhesiveness can be used without any problem. That is,
The back pressure generated by the driving of the zipper 4 causes fluidization, improves adhesion to the wall to be adhered, and enables degassing and joining for integration.

Both side surfaces of the elastic gasket 1 are
The surface may be a flat surface, but the bonding surface is a silicone rubber elastic body formed on a rough surface, and the reactive adhesive layer 2 is formed on the rough surface.

The zipper fitting portion 3 is a concave groove extending in the longitudinal direction of the elastic gasket 1 and is made of rigid metal, hard rubber or hard synthetic resin, and is press-fitted into the concave groove. The taper end 4 ₂ and the zipper 4 having the engaging concave and convex portion 4 ₁ are driven and fixed, and a back pressure is generated to fluidize the reactive adhesive layer 2 by the displacement of the elastic gasket 1 and the interface of the adhered wall body. It is considered to accelerate degassing and improve the wettability and enhance the adhesion reliability. In this case, it is preferable that both end edges of the reactive adhesive layer 2 are located inward of the end edges of the elastic gasket so that burrs bulging from the end edges at the time of mounting and fixing are not generated.

Further, as the protective film 5, a releasable film or tape is used, and it is inserted together with the elastic gasket 1 in a fixed gap between the adhered walls, and only the protective film 5 is pulled out in a non-press contact state. It is good to cover and protect the reactive adhesive layer 2 in a form in which the pull-out knob end 5 ₁ is rolled on one end side of the protective film 5, that is, on the outer side surface in the longitudinal direction of the elastic gasket, to prevent dust pollution. , It is useful for prevention of adhesion of catalyst poison and mutual adhesion and improvement of workability.

In the example of FIG. 4, the reaction type adhesive layers 2 and 2 on both side surfaces of the elastic gasket 1 are wrapped and covered with a single protective film to simplify the extraction work. The mold adhesive layer 2 is not divided into both side surfaces, and a reactive adhesive layer (not shown) is continuously provided also on the insertion end surface side of the elastic gasket 1 to enhance the sealing property by integrally bonding with the backer material. You can also Incidentally, the locking uneven portion 4 ₁ of the zipper 4, the back pressure generating elastic gasket 1 is equalized to Sanya in the longitudinal direction and plural rows formed in the depth direction of the zipper engaging portion 3 It is better to do so.

In the example of FIG. 5, the fixed elastic gasket 1 is inserted between the aluminum mold member 6 and the glass plate 7 so as to be joined and integrated, but the stopper 6 provided together with the backer member 8 is provided on the aluminum mold member 6. _{In the} form of being fixed to ₁ , the reaction of the reactive adhesive layer 2 is performed by driving the zipper 4 so that workability can be simplified.

In the example of FIG. 6, the elastic gasket 10 is made of hard rubber, has a reactive adhesive layer 12 such as a silicone-based reactive adhesive rubber layer on one side, and the other side is inward with the notch 11 as a base line. A notch-folding type (FIG. 6) in which a zipper driving fitting portion 13 is formed between the facing surfaces by driving the two folds with a gap therebetween.
a), or a reaction type adhesive layer 12 is attached to one side of a flat elastic gasket 10 _{1 made} of soft rubber or foamed rubber, and the reaction type adhesive layer 12 side is placed on the outside to form a gap in two folds. A flat bent shape (FIG. 6b) in which the gap between the facing surfaces of the bent and bent portions is the zipper driving fitting portion 13 can be simplified and effectively performed on site.

In the examples shown in FIGS. 1 to 5, the elasticity of the elastic gasket 1 is compressed and inserted between the walls to be bonded and fixed by the reactive adhesive layer 2. After the protective film 5 on the reactive adhesive layer 2 of the gasket 1 is pulled out and removed, a zipper 4 made of a hard material is driven into the zipper fitting portion 3 formed on the outer side surface of the elastic gasket in the longitudinal direction to fix the elastic gasket 1. The reaction-adhesive layer 2 is swollen and deformed to be fluidized, and the reaction-adhesive layer 2 is fluidized and adhered to be integrated with the wall body.

Further, in the example of FIG. 6, the elastic gasket is a flat belt-like member, and the reaction type adhesive layer side adhered on one side is outside and the elastic gasket is formed in a U-shape along the longitudinal center line. It can be installed on site with good workability as a driving seal construction method in which it is folded and inserted between the walls to be adhered, and a hard zipper is driven into the gap formed between the folding facing surfaces to press and solidify.

In order to improve the workability in cold regions, the curing reaction of the reactive adhesive layer does not proceed under severe cold conditions such as 10 ° C. or less in winter and −10 ° C. in winter, and the reliability of adhesion is significantly increased. It is possible to accelerate the curing reaction of the adhesive rubber layer by using metal zipper such as SUS, hard conductive rubber zipper, etc., and heating by energizing and heating to about 40 ° C to 80 ° C. is there.

As in these examples, the elastic gasket 1
Is a dry method in which the reaction type adhesive layers on both sides of the elastic gasket are reacted and cured by the bonded reaction catalyst layer to the joint that is applied to the wall, there is no influence of humidity compared to the conventional wet sealant construction method, and the temperature It takes less than 1 week to complete curing, but the curing time (construction period) used to take 3 to 4 weeks is now 1 to 3 days, and the bonding strength can be increased 3 to 5 times, which is useful for preventing dust contamination and oligomers. .
