【Example】

 Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. FIG. 3 shows an example of a joint material for a carten wall according to the present invention. In the figure, reference numeral 10 is a joint material, and each of the joint materials 10 is shown in FIG. The ten wall panels 11 and 12 are attached and fixed in an inverted L shape from the right end edge to the lower end edge. The joint material 10 ensures the watertight function and the fireproof function between the two curtain wall panels 11 and 12 at the same time.

As shown in FIG. 1, the joint material 10 is a hollow secondary waterproof gasket material 13 formed of a waterproof material such as silicone sponge rubber having elasticity, and a ceramic fiber or glass fiber having elasticity. And a fire-resistant joint material 14 formed of a heat-resistant material such as a rubber. The fire-resistant joint material 14 is incorporated into the secondary waterproof gasket material 13 to form a single product.

As shown in FIG. 1, the secondary waterproof gasket material 13 has a substantially rectangular groove-shaped fixing portion 13 a located on the base end side, and a C provided integrally on the tip side of the fixing portion 13 a. As shown in FIG. 1, the length from the base end surface of the fixed portion 13a to the tip of the deformed portion 13b is the same as that of the curved portion. It is set to a value larger than the gap G between the wall panels 11, 12. Therefore, when the secondary waterproof gasket material 13 is interposed between the two curtain wall panels 11 and 12, the secondary waterproof gasket material 13 is mainly used as shown in FIG. The deformable portion 13b is elastically deformed so that the outer surface of the distal end of the deformable portion 13b is brought into close contact with the curtain wall panel 12 under pressure.

As shown in FIG. 1, at the central portion of the base end of the fixing portion 13 a, there is provided a separation portion 15 for incorporating the fireproof joint material 14 into the secondary waterproof gasket material 13, as shown in FIG. The cut-off portion 15 is provided so as to extend in the longitudinal direction of the sheet material 13. After the fire-resistant joint material 14 is incorporated, the cut-off portion 15 is covered with a waterproof sheet 16 attached to the outer surface of the fixed portion 13a. It has a waterproof structure. A non-woven fabric made of, for example, butyl is used for the waterproof sheet 16, and due to the rough state of the surface of the waterproof sheet 16, when the fixing portion 13a is adhered and fixed to the curtain wall panel 11, sufficient adhesion is achieved. It is designed so that you can get a fixing strength.

On the other hand, as shown in FIG. 1, the refractory joint material 14 is formed in the shape of a rod having a rectangular cross section having a width substantially the same as the inner width dimension of the fixed portion 13a, and the outer peripheral portion thereof is, for example, It is covered with an outer cover film 17 made of synthetic resin. The outer cover film 17 can prevent the felt-like joint material 14 from collapsing or being damaged when the fire-resisting joint material 14 is incorporated into the secondary waterproofing gasket material 13 or the like. In addition, as will be described later, when the fireproof joint material 14 is attached and fixed to the fixing portion 13a, a stable attachment and fixing force can be obtained.

As shown in FIG. 1, the base portion of the refractory joint material 14 is inserted into the fixed portion 13a and is fixedly adhered to the inner surface of the fixed portion 13a. It is in contact with or close to the inner surface of the tip of 13b. The dimension from the base end to the tip of the fire resistant joint material 14 is set to be larger than the gap G between the two curtain wall panels 11 and 12, as shown in FIG. When the joint material 14 is interposed between the two curtain wall panels 11 and 12, as shown in FIG. 2, the joint surface 14 is elastically deformed in the vertical direction in the figure, and the front end surface and the base end surface of the fireproof joint material 14 are The inner wall of the secondary waterproof gasket material 13 is brought into close contact with the inner surface under pressure.

Further, as shown in FIGS. 1 and 2, a large space S is formed between the refractory joint material 14 and the inner surface of the deformable portion 13b. Does not hinder the free elastic deformation of the secondary waterproof gasket material 13. That is, the secondary waterproofing gasket material 13 is elastically deformed in substantially the same shape with and without the fireproof joint material 14. As a result, as shown in FIG. 3, even when the joint material 10 is arranged at the corner portion of the curtain wall panel 11, the joint material 10 can be stably and closely attached to the curtain wall panel 12. It is supposed to do. This will be described in detail later.

Next, the operation of this embodiment will be described. When manufacturing the joint material 10, the secondary waterproof gasket material 13 and the refractory joint material 14 are separately manufactured, and the outer peripheral portion of the refractory joint material 14 is covered with the outer cover film 17. At this time, the outer coating film 17 covers the outer shape of the refractory joint material 14 in the unloaded state as it is, or even if the refractory joint material 14 is tightened, the outer shape of the refractory joint material 14 shrinks slightly. Be careful not to overtighten the refractory joint material 14.

Next, the fixing portion 13 a of the secondary waterproofing gasket material 13 is divided into two through the separating portion 15, and the inner surface of the fixing portion 13 a or the base end outer surface of the fire-resistant joint material 14, that is, the jacket film 17 is divided. Apply an adhesive or the like to the outer surface of the. Then, the base end portion of the fireproof joint material 14 is attached and fixed to the inner surface of the fixing portion 13a. After that, a waterproof sheet 16 is attached and fixed to the outer surface of the base end of the fixing portion 13a with an adhesive or the like, and the cut-off portion 15 has a waterproof structure. As a result, the joint material 10 is completed.

Then, from the right end edge to the lower end edge of each carten wall panel, for example, in the case of FIG. Stick 10 and fix. This sticking and fixing is usually carried out by applying an adhesive or the like to the outer surface of the waterproof sheet 16, but it is also possible to apply an adhesive or the like to the carten wall panels 11 and 12, and a double-sided adhesive tape. It is also possible to use -p or the like.

Next, the carten wall panel 11 is fixed to the wall surface of the high-rise building via a fastener (not shown), and the carten wall panel 12 is brought close to the carten wall panel 11. While maintaining a predetermined gap G in the meantime, the curtain wall panel 12 is fixed to the wall surface via the fastener. Then, as shown in FIG. 2, mainly the deformable portion 13b of the secondary waterproof gasket material 13 is elastically deformed, and the outer surface of the tip thereof is brought into close contact with the outer surface of the carten wall panel 12 under pressure and the fire-resistant joint material. 14 is elastically deformed, and its tip comes into close contact with the inner surface of the tip of the deformable portion 13b under pressure. As a result, the watertight function and the fireproof function between the two curtain wall panels 11 and 12 are simultaneously secured.

By the way, the secondary waterproof gasket material 13 and the fire-resistant joint material 14 are connected to each other only at the base end side, and the tip side of the fire-resistant joint material 14 and the deformed portion 13b are completely free. In addition, a sufficiently large space S is secured between them. Therefore, even when the secondary waterproof gasket material 13 is subjected to an oblique force when approaching the curtain wall panel 11 and the deformed portion 13b is inclined, for example, to the left in FIG. The material 14 is not deformed, and it can be brought into close contact with the inner surface of the tip of the deformable portion 13b in a state in which the front end surface of the material 14 is parallel to the outer surface of the curtain wall panel 12. Therefore, sufficient fire resistance can be obtained.

Further, the deformed secondary waterproof gasket material 13 normally returns to the initial state shown in FIG. 1 by its own restoring force, but in the temporarily deformed state, the carten wall panel 12 is kept. Even when it comes into close contact with the above, since the outer surface of the deformable portion 13b has an arc shape, a sufficient degree of close contact can be obtained.

That is, since the outer surface of the deformable portion 13b has an arc shape, even when the outer surface of the carten wall panel 12 is contacted from an oblique direction, the contact position is the starting point of the carten wall panel 12. Deforms smoothly according to the shape of the outer surface, and sufficient adhesion is obtained. Therefore, even at the corner portion of the curtain wall panel 11, the tip of the deformed portion 13b surely adheres to the curtain wall panel 12, and there is no problem that a gap is formed at this portion.

Since the joint material 10 is composed of the secondary waterproof gasket material 13 and the fireproof joint material 14, the joint material 10 is interposed between the both curtain wall panels 11, 12. Only by doing so, it is possible to obtain the watertight function and the fireproof function at the same time.

FIG. 4 shows a second embodiment of the present invention. Instead of the separation portion 15 of the first embodiment, a separation portion 25 is used, and the waterproof sheet 16 is omitted. Of.

That is, as shown in FIG. 4, the separating portion 25 is configured by stacking the left and right end portions of the deformable portion 13b in a two-ply shape, and this overlapping portion is a gasket material for secondary waterproofing. After the refractory joint material 14 is incorporated into the inside 13, it is attached and fixed by an adhesive or the like. In other respects, the structure is the same as that of the first embodiment and the operation is the same.

Therefore, by using the separating portion 25, a sufficient waterproof structure can be obtained by itself, and the waterproof sheet 16 in the first embodiment can be omitted.

FIG. 5 shows a third embodiment of the present invention, in which the joint material 10 is adhered and fixed not only to the carten wall panel 11 but also to the carten wall panel 12. The deformed portions 13b of the joint material 10 are in close contact with each other. In other respects, the structure is the same as that of the first embodiment and the operation is the same.

However, the two joint members 10 are butted to each other and jointed between the carten wall panels 11 and 12, so that the base end portion of each joint member 10 can be connected to each carten wall panel 11. Since it is attached and fixed to the and 12, it has a completely waterproof structure, so a more stable watertight function can be obtained.

In each of the above-described embodiments, the case where the secondary waterproof gasket material 13 is composed of the substantially square groove-shaped fixing portion 13a and the C-shaped cylindrical deforming portion 13b has been described. The outer surface of the tip of the secondary waterproof gasket material 13 has an arcuate cross-section, and a sufficient space S is formed between the secondary waterproof gasket material 13 and the fireproof joint material 14, especially between the tip portions of both. As long as the refractory joint material 14 does not hinder the elastic deformation of the secondary waterproof gasket material 13, the same effect can be obtained with any structure. Therefore, it is not limited to the structure of each of the above embodiments. The same applies to the refractory joint material 14.

[0045]

[Effect of the device]

 As described above, according to the present invention, since the joint material is constructed by incorporating the fireproof joint material in the secondary waterproof gasket material, it is only necessary to interpose this joint material between the pair of curtain wall panels. Thus, the watertight function and the fireproof function can be secured at the same time, and the workability can be greatly improved.

In addition, at least the outer surface of the tip of the secondary waterproof gasket material is formed in an arcuate cross section, and the space between the secondary waterproof gasket material and the fireproof joint material allows the secondary waterproof gasket material Since the structure is such that the refractory joint material does not hinder elastic deformation, sufficient water-tightness and fire resistance can be obtained even at the corners of the curtain wall panel, and the interior of the gasket material for secondary waterproofing can be obtained. There are no problems associated with the incorporation of refractory joint materials.

In the present invention, the secondary waterproof gasket material is formed into a substantially keyhole-shaped cross section from the fixed portion and the deformed portion, and the base end surface of the fixed portion is formed on one of the curtain wall panels. Since it is fixed, even if an external force is applied, the fixing state to the curtain wall panel is stable, and the deformed part follows the shape of the other curtain wall panel or other joint material. Since it deforms reasonably, it is possible to further improve the adhesion.

In addition, since the fixing portion is provided with a separating portion, and the separating portion has a waterproof structure with a waterproof sheet disposed on the outer surface of the fixing portion, it is easy to assemble the fireproof joint material, and the watertight joint is sufficiently watertight. Performance is obtained.

Further, since the fire-resistant joint material is formed into a rectangular rod shape in which the base end is fixed to the inner surface of the fixed portion and the tip end is in contact with or close to the inner surface of the deformed portion, the manufacture of the fire-resistant joint material is easy. In addition, a large space is secured inside the deformed portion, and even if the deformation is large, the fire resistant joint material does not hinder the elastic deformation of the secondary waterproof gasket.

Further, since the fire-resistant joint material is formed of ceramic fibers, sufficient fire-resistant performance is obtained, and since the outer surface of the fire-resistant joint material is covered with the covering film, the fire-resistant joint material collapses during handling. There is no risk of damage and easy handling.
