Accordingly, as shown in FIG. 2, protrusions 110 are formed on the inner circumferential surface of the interlayer penetrating sleeve 100.

That is, since the projecting step 110 is provided at a portion corresponding to the bottleneck 110 of the interlayer penetration sleeve 100, the same reference numerals are used for the bottleneck 110 and the protruding step 110 in this specification. .

Meanwhile, FIG. 17 is a flowchart illustrating an execution process of the inter-layer piping construction method according to an embodiment of the present invention. Referring to FIG. 17, a description will be made of a process of performing an interlaminar piping construction method according to an embodiment of the present invention. First, the constructor includes an interlayer penetration sleeve 100 having a protruding protrusion 110 on an inner circumferential surface thereof as shown in FIG. (S710). Then, the concrete 400 is placed outside the interlayer penetration sleeve 100 to fix the interlayer penetration sleeve 100 (S720).

Next, the constructor installs the granulation pipe 200 in the inner space of the interlayer penetration sleeve 100 as shown in FIG. 2 (S730). The granulation piping 200 is installed in the center of the inner space of the interlayer penetration sleeve 100 such that the cross section of the granulation piping 200 installed in the inner space of the interlayer penetration sleeve 100 is concentric with the cross section of the interlayer penetration sleeve 100 However, in the construction process, the granular pipe 200 may not be installed in the center, but may have eccentricity.

In order to seal the space between the granulation pipe 200 and the penetrating sleeve 100 to prevent falling of the refractory material despite the eccentricity of the granulating pipe 200 which is not constant according to such a site condition, A first blocking plate 310 as shown in FIG. 3 has been proposed.

The first blocking plate 310 is preferably made of a nonflammable material and the outer diameter of the first blocking plate 310 is made equal to the upper inner diameter D1 of the interlayer penetrating sleeve 100.

In order to facilitate insertion of the granulation pipe 200 into the inner space of the first blocking plate 310, a slit formed near the narrowest part of the rim of the first blocking plate 310, as shown in FIG. 3, It may be preferable to manufacture it.

4, the constructor is inserted through the slit from the upper part of the granulating pipe 200, and then the first blocking plate 310 is dropped into the space between the granulating pipe 200 and the interlayer penetrating sleeve 100, 1 blocking plate 310 may be seated on the protrusion 110 of the inner circumferential surface of the interlayer penetration sleeve 100 (S740).

The hole formed in the first blocking plate 310 is located at the center of the first blocking plate 310 and the hole having a diameter equal to the outer diameter of the granulating pipe 200 is formed in a predetermined length: that is formed by being cut along the circumference of the (linear length S, about 2cm or more) by one line while moving in the direction circles formed continuously (O → 1 2 O).

4, the constructor is inserted through the slit from the upper part of the granulation pipe 200 so as to fill the space between the granulation pipe 200 and the interlayer penetration sleeve 100 as much as possible, 310, and thus the first blocking plate 310 is seated on the protrusion 110 (S750).

On the other hand, the eccentric length d spaced from the center of the through sleeve 100 of the granular pipe 200 is defined by the following equation (1) in relation to the lower inner diameter D2 of the through sleeve and the outer diameter D3 of the granular pipe 200 Is defined as Equation (1).

Figure pat00001

That is, according to Equation (1), the maximum value of the eccentricity length d is (D 2 -D 3) / 2. Therefore, in order to apply the present invention to the maximum eccentricity, It is preferable that the straight line distance S in the first blocking plate 310 at the point (D2-D3) / 2 in FIG.

Figure pat00002

When the outer peripheral surface of the granulation pipe 200 is in close contact with the inner surface of the lower tube of the penetrating sleeve 100 due to the occurrence of the maximum eccentricity, the first blocking plate 310 is inserted into the granulation pipe 200 and the penetrating sleeve 100, The width P1 of the narrowest part of the rim of the first blocking plate 310 is equal to the width T of the protrusion 110 as shown in Equation 3 below .

Figure pat00003

On the other hand, if the width of the widest part of the rim of the first blocking plate 310 is defined as Q1, the following relationship is established as shown in Equation (4) below.

Figure pat00004

On the other hand, the installer must fill the remaining space as shown in FIG. 4 which is not filled by the first blocking plate 310.

Accordingly, in the present invention, a second blocking plate 320 as shown in FIG. 5 is proposed. In order to facilitate insertion of the granulation pipe 200 into the inner space of the second blocking plate 320, a slit formed near the narrowest portion of the rim of the second blocking plate 320 as shown in Fig. 5 It may be preferable to manufacture it.

Accordingly, the constructor inserts the second blocking plate 320 as shown in FIG. 5 through the slit from the upper part of the granulating pipe 200, and then drops the space between the granulating pipe 200 and the interlayer penetrating sleeve 100 The second blocking plate 320 is seated on the first blocking plate 310 to fill the space between the first blocking plate 310 and the granulation pipe 200 as shown in FIG.

6, a circular hole having a diameter D3 equal to the outer diameter D3 of the granulating pipe 200 is formed in the second blocking plate 320, 320 are coupled to the granulation piping 200, the rim of the second blocking plate 320 fills the remaining space except the space in which the granulation piping 200 is coupled in the hole inside the first blocking plate 310 It is preferable that the second blocking plate 320 is formed in a shape having an eccentric circular hole formed therein.

Meanwhile, it is preferable that the second blocking plate 320 is made of a non-combustible material which is the same material as the first blocking plate 310.

Even when the outer circumferential surface of the granulating pipe 200 is in close contact with the inner surface of the lower tube of the penetrating sleeve 100 due to the occurrence of the maximum eccentricity, the second blocking plate 320 can prevent the granulating pipe 200 and the penetrating sleeve 100, The width P2 of the shortest portion of the rim of the second blocking plate 320 is equal to the width T of the protruding ridge 110 as shown in Equation 5 below .

Figure pat00005

In order to allow the second blocking plate 320 to fill the remaining space except the space in which the granulation pipe 200 is coupled in the hole inside the first blocking plate 310 despite the maximum eccentricity, The width Q2 of the widest part of the rim of the first and second electrodes should satisfy the following expression (6).

Figure pat00006

In addition, in step S750, the constructor may be configured such that the rim of the second blocking plate 320 is separated from the hole inside the first blocking plate 310 by the remaining space excluding the space in which the particulate pipe 200 is coupled The second shield plate 320 is lowered while the direction of the wide part of the rim of the second shield plate 320 is adjusted so that the second shield plate 320 can be filled. Thereby forming a coupling structure of the first blocking plate 310 and the second blocking plate 320 as shown in FIG. 7B.

In addition, even if the granular pipe 200 is biased in any direction within the perforated sleeve 100, the constructor can rotate the first blocking plate 310 and the second blocking plate 320 as necessary as shown in FIG. 7B The space between the granulation pipe 200 and the penetrating sleeve 100 can be filled up.

Meanwhile, in order to enhance the function of filling the space, a wide part of the rim of the second blocking plate 320 may be expanded or deformed into various shapes such as having a protruded arc shape having a separate curvature.

Next, the constructor installs the inflator 210 and the inflator guide plate 230 on the side of the lower end of the granulation pipe 200 as shown in FIG. 8 (S760).

Accordingly, even when the granular pipe 200 of a combustible material is melted due to fire, the inflatable material 210 expands in the direction opposite to the inflatable guide plate 230, thereby filling up the space occupied by the granular pipe 200 .

However, when the granular pipe 200 is made of a steel pipe, the granular pipe 200 is less likely to melt due to fire. Therefore, as shown in FIG. 9, The installation of the guide plate 230 would be unnecessary.

The constructor then charges the refractory material 250 such as mineral wool into the space between the granulation pipe 200 and the interlayer penetration sleeve 100 (S770).
