In general, the semiconductor industry requires many kinds of manufacturing equipment and manufacturing processes that are as complicated as their usability but require very precise precision. Such a semiconductor manufacturing process generally uses a large amount of toxic, corrosive, and flammable gases which are fatal to the human body due to its process characteristics.

For example, in a CVD (Chemical Vapor Deposition) process, which is one of typical semiconductor manufacturing processes, a toxic substance such as a large amount of silane, dichlorosilane, ammonia, nitric oxide, arsine, phosphine, diboron, boron, Use gas.

In addition to the CVD process, various kinds of toxic gases are used in many kinds of semiconductor processes such as plasma etching, epitaxial deposition, and sputtering.

In addition, air is supplied to regulate the temperature and humidity in a production line equipped with various facilities.

The duct body for supplying such air or discharging various toxic gases therein is installed by installing a plurality of branch pipes, and various techniques for installing the branch pipes are proposed.

Such a conventional technique is disclosed in Korean Patent No. 10-0373828 entitled " Method of connecting main pipe to branch pipe "

In the above prior art, a main pipe and a branch pipe connecting one or more synthetic resin branch pipes to a main pipe formed of a synthetic resin are connected to each other so that the inner diameter of the branch pipe is prevented from being narrowed inside the end of the branch pipe The main pipe is provided with a plurality of holes or heat is applied to the holes and the branch pipe in a state where the hole is mechanically machined in the main pipe And a method of connecting the main pipe and the branch pipe for inserting the branch pipe into the hole of the main pipe and coupling them in a molten state.

In addition, there is a prior art 10-2001-0019315 entitled " Main structure of automotive heating device and assembly structure of branching &

In the prior art, a seat is formed at one end of a branch pipe to be seated and fixed around the branch hole of the main outer circumferential surface to communicate the main pipe and the branch pipe, and the main pipe and the branch pipe have the same inner diameter, The main part of the heating system for the automobile, which is fixed to the main pipe by welding, is shown in Fig.

Furthermore, there is a prior art No. 10-0512522 entitled " Device for connecting branch pipes of corrugated steel plate structure "

The conventional technique described above is characterized in that a base portion is formed by molding a corrugation having the same waveform as that of the corrugated steel plate structure and is divided into a plurality of portions so as to cover all the edges of the branch holes, , Wherein the assembled branch pipe connecting device is first fastened to the corrugated steel plate structure and the branch pipe is fastened to the upright portion, thereby facilitating the installation of the branch pipe and the durability of the connecting portion Which can improve the performance of the corrugated steel plate structure.

In addition, there is a prior art 10-1068287 " branch connection structure "

In the prior art, a branch pipe is welded to a branch connection hole formed in a main pipe, and a lower insertion piece formed to be formed on a cut-out portion of the support jaw is supported on a main pipe Which is inserted into the branch connecting hole and is prevented from flowing in any direction of the branch pipe so that final welding of the connecting portion of the branch pipe can be performed without any welding process.

The above-mentioned prior arts disclose the use of welding or the like in order to form a branch pipe in a main pipe or a duct body which is generally used.

However, in recent years, fire accidents in the semiconductor process have caused unprotected exposure to enormous property damage and environmental damage. In particular, most of the materials of ducts and chemical tanks used in semiconductor factories and chemical plants are FRP materials Is being used. FRP (Fiber Reinforced Plastics) materials have excellent mechanical properties and excellent corrosion resistance of plastics. They have a smaller specific gravity than steel materials, have high strength, and are excellent in moldability, and are attracting attention as excellent functional materials. Therefore, it is widely used as a material for toxic gas, acid exhaust gas transfer duct, chemical storage tank and so on.

In the case of FRP, the product is manufactured using flame retardant resin. However, since it is not a non-flammable material in the case of fire, it is expected that the damage will be large when it is damaged by fire. Second damage caused by the stored medicine and gas It is also a tremendous amount that can not be predicted by numbers. In order to minimize such industrial safety damage, it is necessary to develop a nonflammable FRP product. To improve this, a duct having a reinforcing layer containing a nonflammable phenolic resin is used.

However, it is difficult to bond the reinforcing layer and the reinforcing layer at room temperature due to the characteristics of the phenol component when the branch pipe is installed in the duct in which the reinforcing layer is formed, and in the case of applying at room temperature, hardening is not easily occurred, .

In order to solve this problem, conventionally, toxic chemicals may be used for bonding. In such a case, it is difficult to construct and there is a problem that the worker's health is harmed.

Further, in the case of constructing in this manner, it is possible to work only in the factory equipped with the construction equipment, and even when the branching installation is additionally installed in the installed duct, the entire duct is separated and transferred to the factory, .

Specifically, in order to make a phenol duct having excellent corrosion resistance and nonflammability, a corrosion resistant layer is formed and a reinforcing layer containing a phenol component is formed thereon. At this time, a primer is used to improve adhesion between the corrosion resistant layer and the reinforcing layer.

The primer uses a polyester and an epoxy modified urethane. Since the primer has no adverse effect on moisture, the primer uses a moisture curing type principle and has an advantage of excellent adhesiveness, workability and curability, A primer having excellent adhesion to phenol FRP is applied on the vinyl ester FRP layer to improve the adhesion of the two FRP layers. Generally, when phenol FRP is laminated on the vinyl ester FRP layer, the adhesion is not very good because, unlike the vinyl ester resin, the phenol resin is water-soluble and has no chemical bond. In addition, the curing of the phenolic resin is a factor which inhibits the adherence due to the generation of water upon curing due to the condensation reaction.

In addition, when a branch is formed in a phenol duct formed with a reinforcing layer of phenol component, the outer surface of the branch is also formed as a reinforcing layer composed of phenol component, so that the reinforcing layer and the reinforcing layer must be joined.

However, in order to bond the reinforcing layer with the reinforcing layer according to the characteristics of the phenol component, the curing should be performed at a high temperature (80 ° C to 100 ° C) for about two hours. That is, in order to bond the reinforcing layer with the reinforcing layer, the curing can not proceed at room temperature, and only a factory equipped with a facility for a separate curing process is available.

Therefore, when the work is performed on the site in the field, it is difficult to satisfy the hardening conditions due to the nature of the phenol duct, so that hardening does not occur, cracks, corrosion occur, or peeling may occur.

Also, there is a conventional method of connecting by using a different kind of branching system. In this method, a hole is drilled in the main duct to insert a branch of SUS material, and the gap (joint part) is sealed with a resin. . However, this conventional access method causes many problems in the field.

That is, the end of the SUS branch pipe is deeply inserted into the main duct in order to prevent the branch pipe from being easily released from the main duct due to vibration. However, it has been pointed out that the powder is deposited on the end of the branch pipe inserted deeply into the main duct, and corrosion of the branch pipe end is thereby easily caused.

Further, due to vibration of the main duct and use for a long period of time, microcracks are generated in the resin sealing the joint, which causes many problems.

Further, in a state in which the FAB air conditioner is kept in an operating state, there are a few cases in which a branch pipe branching from the main tug is required to be additionally installed. However, the conventional construction method is difficult to meet such a demand.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a phenol duct assembly having a branch pipe,
