In general, the connection of a pipe through a block or a structure is commonly used to connect from both sides with an intermediate connecting pipe called a sleeve, which is called a sleeve joint.

Conventionally, in order to install a pipe to penetrate the block, a hole is drilled in the block and a sleeve is installed around the pipe.

In other words, the sleeve is installed in the through block, and the block and the sleeve are welded and fixed, and then the first pipe is inserted to one side to weld the sleeve and the pipe, and the second pipe is inserted again to weld the sleeve and the pipe to the opposite side. It can be installed through the block.

Figure 1 shows a conventional sleeve connection state, in the welding position in Figure 1 is not welded to the pipe inside the sleeve, it is to weld and fix between the end of the sleeve and the pipe.

However, when the coupling method as shown in the drawing is applied to the sleeve joint, a gap 100 is generated between the inner and outer pipes, and there is a problem in that water accumulates therein.

In addition, when the temperature is low, the standing water is frozen while the volume expands, which causes cracks in the welded portion, which causes the contents to leak out through the cracks.

The present invention has been made in order to solve such a conventional problem, in the welding method of connecting the pipe to the sleeve first weld one side and then fill the gap between the sleeve and the pipe with a filler to eliminate the gap, the second pipe The gap between the sleeve and the pipe is eliminated by inserting the seal into the sleeve, filling it in the sleeve, filling the gap between the sleeve and the pipe, eliminating the gap, and finally joining the sleeve and the pipe. It is an object of the present invention to provide a method of sealing a crevice waterproof inside a pipe sleeve connection to prevent cracking or corrosion of the pipe.

The present invention for achieving the above object is a step of welding the sleeve to the block is formed in the hole for installing the pipe through the block; Welding the outer sleeve and the first pipe after inserting the first pipe into the sleeve on one side of the block; Filling a filler in a gap between the first pipe and the sleeve in the sleeve; Inserting a second pipe having a sealing ring or tape attached to the end thereof in the sleeve; Filling a filler in a gap between the second pipe and the sleeve in the sleeve; And welding and fixing the end of the sleeve to the body of the second pipe.

On the other hand, the filler is characterized in that it uses a waterproof material, such as silicone, epoxy, polymer.

As described above, according to the present invention, unlike the problem in that when the pipes are connected by using the conventional pipe connection method, rusts easily occur in the gaps or holes due to corrosion occur, the present invention fills the gaps with fillers. By using the sealing method that removes the place where water may be accumulated, it prevents the pipe joint from being corroded and prevents the cracks due to the expanded volume of the frozen person. It is a very useful invention to make a joint.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

According to the present invention, welding the sleeve 20 to the block 10 in which the hole is formed to install the pipe through the block 10; A step S1 of welding the first pipe 30 and the outer sleeve 20 into which the first pipe is inserted into the sleeve 20 on one side of the block; Filling a filler (60) in a gap between the first pipe (30) and the sleeve (20) in the sleeve (20); Inserting a sealing pipe 70 or a taped second pipe 40 into the sleeve 20 at an end (S3); Filling a filler (60) in a gap between the second pipe (40) and the sleeve (20) in the sleeve (20); It characterized in that it comprises a; step (S5) of welding the end of the sleeve 20 and the body of the second pipe (40).

In order to install the pipe through the block 10, the sleeve 20 is welded to the block 10 in which the hole is formed. The sleeve 20 is used to interconnect the pipes installed in the block 10, and is pre-welded to be used when connecting the pipes to pass through the block 10.

The welding of the first pipe and the outer sleeve 20 in which the first pipe 30 is inserted into the sleeve 20 at one side of the block is a step of connecting the pipe to the sleeve 20. By inserting the first pipe 30 into the inside of the sleeve 20 is to be fixed by welding the end of the sleeve and the body of the inserted pipe. At this time, a gap is formed between the sleeve 20 and the pipe, and water passing through the pipe may collect in this gap and cause rust.

In order to solve this problem, the welding part 60 is filled in the gap between the first pipe 30 and the sleeve 20, which prevents water from accumulating between the sleeve 20 and the pipe. As the welding unit 60 may use a waterproof material such as silicone, epoxy, polymer, and the like, it is directly filled by using a syringe or the like.

After the filling is completed, a step of sealing the gap by using a welding part 70 or a tape at the end of the pipe may be added to prevent leakage of the welded part 60 between the filling parts.

Now, the second pipe 40, which is connected to the first pipe 30, should be inserted into and fixed to the sleeve 20. Before this, the weld 70 or the tape is wound around the end of the second pipe 40. Insert into the sleeve (20).

The rubber ring or tape wound around the end of the second pipe 40 inserted into the sleeve 20 is wound to fit the gap gap between the sleeve 20 and the second pipe 40 to fill the weld 60. (60) serves to prevent leakage.

Thereafter, the welding portion 60 is filled in the gap between the second pipe 40 and the sleeve 20 in the sleeve 20 so as to fill the gap between the sleeve 20 and the second pipe 40. . In this case, the method of filling the weld 60 may also fill the weld 60 using a syringe or the like by filling the weld 60 in a gap between the sleeve 20 and the first pipe 30.

After the filling of the welding part 60 is completed, the end of the filling sleeve 20 and the body of the second pipe 40 are welded and fixed to complete the connection of the sleeve 20 and the pipe.

On the other hand, Figure 3 is a cross-sectional view showing a horizontal pipe connection sequence of the gap sealing method of the inside of the sleeve 20 of the pipe connection method of the present invention, the first pipe 30 and the sleeve 20 in the sleeve 20. Between the step (S2) for filling the weld 60 in the gap between the) and the step (S3) for inserting the welding pipe 70 or taped second pipe 40 to the sleeve 20 at the end (S3) The step (S2a) of sealing the end of the pipe using the weld 70 or the tape was further performed to prevent the filling from leaking.

Referring to the effect of the present invention made of such a configuration and steps as follows.

In order to install a pipe through the block, a through hole is formed in the block, and the sleeve 20 is inserted into the through hole to fix the weld.

Conventionally, the connection of the pipe is completed by inserting the first pipe 30 into the fixed sleeve 20 to weld the sleeve 20 to fix the sleeve 20 and inserting the second pipe 40 to the other side to fix the weld. .

In this case, in order to prevent the gap between the first and second pipes and the sleeve 20, the welding part 60 should be inserted and sealed. For this purpose, the first pipe 30 is inserted and welded to the sleeve 20 to fix the gap. A weld 60 is filled between the first pipe 30 and the sleeve 20 through the inside of the sleeve 20.

If necessary, the end of the first pipe 30 is sealed with a weld 70 or a tape, and then the second pipe 40 is inserted into the opposite sleeve 20.

However, when the welding pipe 70 or the tape is wound on the end of the second pipe 40 in advance and the second pipe 40 is inserted into the sleeve 20 before the second pipe 40 is inserted, the sleeve 20 and The gap with the second pipe 40 can be blocked, and then the weld 60 is prevented from leaking by filling the weld 60 between the sleeve 20 and the second pipe 40.

After the filling of the weld 60 is completed, the connection installation of the pipe is completed by welding and fixing the end of the sleeve 20 and the body of the second pipe 40.

As a result, when the pipes inside the sleeve 20 are connected, water can be removed to prevent rust from occurring inside the sleeve 20.
