A branch pipe 500 branched from the cooling water pipe 10 is inserted into the first insertion hole 111 and the branch pipe 500 supplies cooling water to the cooling water accommodating space 110 .

The branch pipe 500 is provided with a first coupling plate 510 and a rotary bar 500 disposed on the upper side of the housing 100 after the branch pipe 500 is inserted into the first insertion hole 111. [ The housing 520 is rotated so that the housing 100 is pressed by the first engaging member 530 from the upper side to the lower side so that the first engaging plate 510 and the housing 100 are closely contacted.

The first engagement hole 521 is formed in the rotation bar 520 so that the first engagement member 530 is screwed to the first engagement hole 521 to press the rubber member 540, The rubber member 540 presses the upper portion of the housing 100 so that the branch pipe 500 and the housing 100 are tightly coupled.

One end of the branch pipe 500 is inserted into the first insertion hole 111 of the housing 100 and the other end of the branch pipe 500 is connected to the cooling water pipe 10, 10 is supplied to the cooling water accommodating space 110 through the branch pipe 500.

The housing 100 includes a body portion 120, a first connection portion 121, and a second connection portion 122. The body portion 120 forms an outer shape of the housing 100 and forms the cooling water accommodating space 110 therein. The cooling water accommodating space 110 is configured to receive cooling water supplied from the branch pipe 500.

The first insertion hole 111 communicating with the cooling water accommodating space 110 is formed below the body portion 120 and the third insertion hole 111 communicating with the cooling water accommodating space 110 is formed at the rear side thereof. 113 are formed.

In addition, the first connection part 121 protrudes forward from the body part 120 and is connected. Here, the first connection part 121 is formed to have a second insertion hole 112 communicating with the cooling water accommodating space 110.

One end of the first connection part 121 protrudes forward from the body part 120 and the second connection part 122 is connected to the other end of the first connection part 121, And is connected to the first connection part 121. [

The second connection part 122 is formed such that the second connection part 122 and the body part 120 are separated from each other by a predetermined distance as the first connection part 121 protrudes forward, 122 have a male-nozzle coupling hole 123 formed therein.

Here, when the second connection part 122 protrudes from the first connection part 121, the shape of the second connection part 122 may be variously shaped like a circle, an ellipse, or a rectangle.

The first insertion hole 111, the second insertion hole 112 and the third insertion hole 113 are formed in the housing 100 so that the branch pipes 500, (200) and the arm nozzle (300) are inserted.

Specifically, the male nozzle 200 is inserted into the second insertion hole 112, and the arm nozzle 300 is inserted into the third insertion hole 113.

Here, the male nozzle 200 includes a guide unit 210 and a second coupling plate 220.

The guide part 210 guides the path through which the reinforcing bar is moved, and the guide part 210 is preferably a tube having a hollow hole.

In other words, the guide part 210 is formed as a long tubular body so that the inner diameter D1 formed at the front is reduced by a predetermined length and then the inner diameter D2 of the same size is extended. This is to make the inner diameter D1 at the front wide so that the introduction of the high-temperature steel into the guide part 210 is facilitated.

An O-ring insertion groove 211 is formed on an outer circumferential surface of the guide portion 210 and an O-ring 250 is coupled to the O-ring insertion groove 211. The O-ring 250 may be at least one or more than two in the guide part 210. When the male nozzle 200 and the housing 100 are coupled to each other, the O- (112).

This is to prevent the cooling water accommodated in the cooling water accommodating space 110 from flowing out along the second insertion hole 112 when the male nozzle 200 and the housing 100 are coupled.

The guide part 210 may have a second coupling plate 220 protruding outward and the second coupling plate 220 may have a shape corresponding to the second coupling part 122.

A second coupling hole 221 is formed in the second coupling plate 220 so that the male nozzle 200 and the housing 100 are coupled by the second coupling member 230.

In other words, the second engaging member 230 is composed of a bolt 231 and a nut 232, and the bolt 231 passes from the front through the second engaging hole 221 and the male-nozzle engaging hole 123 And the male nozzle 200 is fixed to the housing 100 by being tightened by the nut 232.

If the second coupling plate 220 and the second coupling portion 122 are separated from each other due to the distance adjustment of the front and rear of the male nozzle 200, the second coupling plate 220 and the second coupling portion 122 are provided with a spacing member 240 to couple the male nozzle 200 and the housing 100 together.

At this time, the spacing member 240 is formed with a hole through which the second engaging member 230 is inserted, one surface of the spacing member 240 is in close contact with the second engaging plate 220, and the spacing member 240 Is in close contact with the second connection part 122 so that the male nozzle 200 and the housing 100 are coupled to each other to prevent the swing.

The thickness of the spacing member 240 may be varied according to the distance of the male nozzle 200 and may be varied by varying the distance of the male nozzle 200 through a plurality of stacks of the thin spacer 240. [ .

The spacing members 240 may be individually formed as shown in the drawing, or they may be connected in a shape corresponding to the second coupling plate 220.

7) and the second coupling plate 220 '(see FIG. 7) are circular, the second coupling hole 221' (see FIG. 7) (See FIG. 7) by a predetermined length along the circumference of a circle having a predetermined radius r from the center of the second coupling hole 220 '(see FIG. 7).

7) is formed by a predetermined length along the circumference of the circle having the predetermined radius (r), the worker presses the male (male) Since the engaging positions of the second engaging hole 221 and the male nozzle engaging hole 123 can be easily held when the nozzle engaging hole 123 and the second engaging hole 221 are engaged with each other, The engagement time of the housing 100 can be shortened.

The second coupling plate 220 according to the first embodiment of the present invention will be described as the second coupling plate 220 having a rectangular shape and the second coupling plate 220 ' 6) will be described as the second coupling plate 220 '(see FIG. 6) having a circular shape.

The arm nozzle 300 includes a protrusion 310 and a third coupling plate 320. The protrusion 310 is inserted into the third insertion hole 113, The housing 100 and the arm nozzle 300 are coupled to each other.

The outer diameter of the protrusion 310 inserted into the third insertion hole 113 is preferably set to correspond to the inner diameter of the third insertion hole 113, And an o-ring (not shown) may be further provided so that the o-ring (not shown) is brought into close contact with the third insertion hole 113 when the arm nozzle 300 and the housing 100 are coupled.

This is to prevent the cooling water accommodated in the cooling water accommodating space 110 from flowing out along the third insertion hole 113 when the arm nozzle 300 and the housing 100 are coupled.

The third engaging plate 320 protrudes outward from the protrusion 310 so that the third engaging plate 330 is engaged with the third engaging plate 320 while the third engaging plate 320 is in close contact with the body 120. [ The housing 100 and the arm nozzle 300 are coupled to each other.

The third engaging member 330 is inserted into the third engaging hole 321 formed in the third engaging plate 320 and then screwed into the arm nozzle engaging hole 114 formed in the housing 100. [ And the arm nozzle 300 is fixed to the housing 100.

The exhaust pipe 400 is integrally coupled to the arm nozzle 300.

In the above-described temp core apparatus 1000, the cooling water supplied from the branch pipe 500 is sprayed to the high-temperature reinforcing bars guided from the front, thereby making the high-temperature reinforcing bars water-cooled.

At this time, the amount of cooling water sprayed by the high-temperature reinforcing bar is determined by the outer surface of the guide part 210 located inside the housing 100 and the inner surface of the arm nozzle 300 located inside the housing 100 And is adjusted according to the gap L of the side surface.

In other words, when the male nozzle 200 is moved forward in a state where the female nozzle 300 is fixed to the housing 100, the gap L is widened, The amount of the cooling water discharged to the discharge pipe 400 is increased and when the male nozzle 200 is moved backward while the arm nozzle 300 is fixed to the housing 100, The amount of cooling water discharged to the discharge pipe 400 is reduced.

When the housing 100 and the male nozzle 200 are coupled with each other in a state where the center of the housing 100 and the male nozzle 200 are not aligned with each other, The length of the gap L is not the same along the circumference, so that the amount of cooling water discharged to the discharge pipe 400 varies depending on the position. That is, due to the difference in the clearance L, the cooling water is unevenly discharged to the discharge pipe 400.

This is because the cooling water discharged into the high-temperature reinforcing bars differs depending on the position, so that the high-strength reinforcing bars do not have uniform strength. Therefore, the centering of the housing 100 and the male nozzle 200 when the housing 100 and the male nozzle 200 are coupled must be checked.

One end of the branch pipe 500 is inserted into the first insertion hole 111 of the housing 100 and the housing 100 is inserted into the first insertion hole 111 of the housing 100. [ The housing 100 is pushed downward by the first engaging member 530 so that the housing 100 is joined to the branch pipe 500. In operation S510,

The guide portion 210 is inserted into the second insertion hole 112 and the second coupling member 230 is inserted through the second coupling hole 221 and the male nozzle coupling hole 123 The male nozzle 200 and the housing 100 are coupled to each other. (S520)

At this time, when the second coupling plate 220 and the second coupling portion 122 are separated from each other, the spacing member 240 is provided between the second coupling plate 220 and the second coupling portion 122, Thereby preventing shaking of the nozzle 200 and the housing 100.

A protrusion 610 of the inspection nozzle 600 having the same inner diameter as the arm nozzle 300 is inserted into the third insertion hole 113 and protruded outward from the protrusion 610 620 are coupled to the housing 100 by the third engaging member 330. (S530)

Since the discharge pipe 400 is not coupled to the inspection nozzle 600, the worker can visually confirm the centering of the housing 100 and the male nozzle 200, The centering of the female nozzle 300 can be inspected in advance and the gap L between the male nozzle 200 and the female nozzle 300 can be measured and inspected beforehand. It can be checked in advance that the exhaust gas is uniformly discharged to the discharge pipe 400.

Here, the worker may measure the centering and the distance L of the clearance through various measuring equipments as well as the naked eye.

This is because the distance L between the housing 100 and the male nozzle 200 can not be checked when the exhaust pipe 400 is integrally coupled to the female nozzle 300 It is for solving.

When the temp core apparatus 1000 is used for a long time, vibration may be applied to the temp core apparatus 1000. When vibrations are applied to the temp core apparatus 1000, the housing 100 and the male nozzles 200 can be changed.

The user can easily recognize the problematic portion by using the inspection nozzle 600 with respect to the positional change of the housing 100 and the male nozzle 200. The inspection nozzle 600 The central alignment of the housing 100 and the male nozzle 200 and the distance of the gap L are readjusted. (S540)

Next, the inspection nozzle 600 is detached from the housing 100, and the arm nozzle 300, to which the discharge pipe 400 is integrally coupled, is coupled to the housing 100. (S550, S560)

Cooling water is supplied to the cooling water accommodating space 110 through the branch pipe 500 and cooling water supplied to the cooling water accommodating space 110 is formed by the male nozzle 200 and the arm nozzle 300 And discharged to the discharge pipe 400 through the gap L. [ (S570)

Next, a high-temperature reinforcing bar is guided from the front of the male nozzle 200 to the discharge pipe 400, and the high-temperature reinforcing bar is subjected to water-cooling treatment by the cooling water discharged through the gap L . (S580)

As described above, according to the first embodiment of the present invention, no separate thread is formed on the outer side surface of the guide part 210, so that the coupling between the male nozzle 200 and the housing 100 is facilitated And the operator can quickly adjust the fine distance between the male nozzle 200 and the housing 100.

The worker visually checks the centering of the housing 100 and the male nozzle 200 and the distance L between the male and female nozzles 200 and 300 through the inspection nozzle 600 So that cooling water can be uniformly discharged to the discharge pipe 400 through the gap L and the misalignment of the center of the male housing 200 and the male nozzle 200, The cooling failure of the reinforcing bar produced due to the gap L of the nozzle 300 is blocked in advance.

Here, the display unit 224 has a scale shape, and an operator adjusts the distance that the male nozzle 200 'is inserted into the housing 100'.

In other words, the operator rotates the second engaging plate 220 'from the first insertion reference point 125 and the second insertion reference point 225 to guide the guide unit 210' to the housing 100 ' The guide portion 210 'is rotated until the second connection portion 122' and the second coupling plate 220 'are in contact with each other.

At this time, the insertion length of the male nozzle 200 'in a state in which the second coupling portion 122' and the second coupling plate 220 'are in contact with each other is determined by the pitch of the thread, The operator can determine the length of the second coupling plate 220 'from the state where the second coupling portion 122' and the second coupling plate 220 'are in contact with each other through the scale of the display portion 224 (See L in FIG. 4) between the male nozzle 200 'and the female nozzle 300' by rotating the guide portion 210 'forward by a desired length.

The worker moves the guide part 210 'forward by a desired length according to the thickness of the reinforcing bar to be cooled and then rotates the male nozzle 200' and the housing 100 ' Lt; / RTI >
