The inner tube of the multilayer tubular structure is made of synthetic resin or metal. A hard vinyl chloride pipe is mainly used as the synthetic resin inner pipe, and a multilayer tubular structure or a drainage pipe is constructed by combining this with an outer layer pipe mainly composed of fire-resistant materials such as hydraulic inorganic materials and inorganic fibers. It is used for purposes such as ventilation pipes attached to drainage pipes, power distribution pipes, water supply pipes, and supply/exhaust ducts. By adopting this configuration, while taking advantage of the features of the inner pipe such as workability, durability, and low cost and low water noise, the fire-resistant outer layer of the pipe allows the inner pipe to be transmitted to the next room or upper floor in the event of a fire. It has the function of preventing the spread of fire and minimizing reef damage.

The metal inner tube may be made of materials such as aluminum or galvanized stainless steel, and a combination of this and an outer tube made of a fire-resistant material can be used, for example, in group cable ducts, to provide protection in the event of a man-made disaster. In addition to increasing the energization time and securing the time for evacuating Mlfl, it is also used, for example, in an air supply/exhaust tact to prevent the risk of fire spread due to overheating.

When piping these multilayer tubular structures through partitions that separate partitions between upper and lower floors or adjacent rooms, the inner pipes may be directly glued or welded, or they are usually of the same type. Connect piping using various types of fittings such as T-shaped, Y-shaped, L-shaped, etc., which are coated. In the case of connections using pipe fittings, the pipe materials and pipe fittings must be fire resistant fH! 6 Even if the outer tube is covered with a material made of material, it is unavoidable that there will be a discontinuous part between the outer tubes at the connection part. There is insufficient safety against hot air or infiltrating fire or heat.

Under these circumstances, the method of filling or applying a mixture of fire-resistant hydraulic material and water to the joints is often used, which not only requires a lot of labor but also usually requires a small space for piping construction. Therefore, it is difficult to reliably carry out this construction all the way to the back of the pipe, but it is also possible to install a joint band at the connection between the outer layers, in which a noncombustible sealing layer made of a noncombustible inorganic fiber material is provided on one side of the metal strip material. We are also developing a method to securely fix the joint from the second place. Compared to the joint filling or coating method described above, it is easier to install and has the advantage of being able to reliably cover the joints on the back of the pipe even in narrow spaces.

Methods for fixing a noncombustible sealing layer made of an inorganic fibrous material to one side of a metal strip material include a method in which a sword-like claw piece is provided on the surface of the metal strip material in advance and fixed to it in a prick-like manner, and a method using adhesive. A method of fixing with an agent may be considered. In the former case, the fixing operation itself is easy, or it requires a processing step for the metal strip material, and is also technically difficult, so there are problems in practical use. On the other hand, the latter causes problems with fire resistance with organic adhesives, and inorganic adhesives generally take a long time to cure, so they must be left horizontally for a long time to prevent the adhesive from losing its shape or shifting until it hardens. In addition to requiring a large space to manufacture, there is a fundamental problem in that the metal strip material has very little flexibility.When this metal strip material is forcibly bent and fixed in a cylindrical shape at the joint, there is a curvature on the inside and outside. Due to the difference in the adhesiveness between the non-combustible sealing layer made of inorganic fiber material and the metal strip material, the adhesion breaks and peels off.
There was an inconvenience that a small hole was formed.

In accordance with these objectives, the present inventors have carried out research with great effort.
As a result of the soaking, a mixture of water and a hydraulic inorganic material containing cationic latex or emulsion of rubber or plastic is used to make metal, -If? We have completed the present invention by discovering that bonding and fixing a non-combustible sealing layer made of an inorganic fibrous material on one side of a board achieves the intended purpose.

The cationic system referred to here refers to latex particles in latex or emulsions, or emulsions that are stabilized by being positively charged, and the surface of the cement and aggregate particles of the present invention is coated with a comb membrane or plasdec. It is believed that when wrapped in a film, it is very well distributed and as a result, above a certain amount added, the hardened cement material acquires elastic properties. On the other hand, when anionic or menionic latex or emulsion is used, the above-mentioned uniform dispersion cannot be obtained, and elastic properties cannot be obtained. When the incombustible sealing layer made of inorganic fiber 4:tFl was applied, the adhesion broke near the metal/ny board, resulting in a gap between the sealing layer and the band plate A∆. It is not possible to prevent the intrusion of fires, etc., as there are many cases where the product is exposed to water. Of course, in this case as well, if latex or emulsion is used for human IIT, it will gradually acquire elastic properties or its fire resistance will be impaired, so it cannot be said to be practical.

Examples of the nonflammable sealing layer made of inorganic fibrous material according to the present invention include asbestos, rock wool, glass fiber, ceramic wool,
Examples include carbon fiber, cloth, and matte.The width of the noncombustible sealing layer may be the same as that of the metal strip material, or may be narrower than that. This is because there is usually a step in the joint of a multilayer tubular structure using a joint of the same type of structure, so the end surface of the nonflammable sealing layer is brought into close contact with the end surface of the joint, which is the rising part of the step. This is because it is best to wrap and fix the joint hunt so that it is wrapped around the outer circumference of the outer tube of the abutted multilayer tubular structure having the smaller outer diameter, with the nonflammable sealing layer behind.

When the outer periphery of the joint of a multi-layered tubular structure manufactured by the method according to the present invention is wound and coated using the above drawings, it can be wrapped around the sealing layer or the metal strip material without coming loose, and moreover, it can be wrapped around the inner tube. Since it is not exposed to or penetrates the surface, even if a man-made disaster occurs in a part of the building, flame will not come into contact with the connection.
The inner tube cannot be damaged by flames. In addition, when the inner tube is made of synthetic resin, even if the inner tube becomes hot and carbonized, the shape of the connecting portion is maintained by the ground hand, so that the tube material as a whole will not be damaged. Furthermore, even if the synthetic resin pipe were to burn, the internal flames would not be blown out through the peripheral wall of the nonflammable coating layer, so the fire would not spread and no debris would be blown into the room.

In addition, the joint hand manufactured by the method of the present invention not only has an extremely simple structure, but also is extremely easy to construct, so it is possible to work on a large number of joints in a short time, and to correctly perform joint construction without requiring any skill. This can greatly contribute to the spread of multilayer tubular structures that constitute complex connections.
