Looking at the piping construction process using the building insert (M) of the present invention configured as described above with reference to Figures 4a to 4i.

Referring to Figure 4a, the fixing pin 300 is fixed to the upper surface of the formwork (100).

That is, when the insert (M) is installed on the upper surface of the formwork 100, the fixing pin (300) is installed so that the insert (M) is not easily collapsed by an external force, so that the insert (M) can be accurately fixed in the installation position.

Next, referring to Figure 4b, the support member 30 is installed to surround the fixing pin 300 fixed to the upper surface of the formwork (100).

That is, the lower inner diameter of the support member 30 is formed to be slightly looser than the diameter of the fixing pin 300 so that the lower portion of the support member 30 surrounds the fixing pin 300 fixed to the upper surface of the formwork 100. do.

Next, referring to FIG. 4C, the coupling holder 50 is installed inside the support member 30.

That is, the edge 52 of the coupling holder 50 is hooked to the lower seating surface 31 inside the support member 30.

Next, referring to Figure 4d, the upper cap 70 is coupled to the support member 30 so that the coupling holder 50 is fixed.

That is, the upper edge of the coupling holder 50 seated on the seating surface 31 of the support member 30 while the upper cap 70 is screwed through the open upper side of the support member 30. A portion of the upper cap 70 is fixed to the inside of the support member 30 while being pushed out.

Here, the edge 52 of the coupling holder 50 seated on the seating surface 31 of the support member 30 is pressed by the upper cap 70 and the inclined surface 53 is stretched in a horizontal state. As shown in 5a, the diameter L1 between the end and the end of the engaging piece 51 forms a diameter corresponding to the diameter L2 of the fastening groove 11 of the coupler 10. Is fixed to

Next, referring to FIG. 4E, concrete CON is poured into the formwork 100.

Next, referring to Figure 4f, after curing the concrete (CON), the formwork 100 with the fixing pin 300 is removed from the concrete (CON).

That is, the insert (M) in which the support member 30, the coupling holder 50, the upper cap 70, etc. are mutually coupled to each other by the support of the fixing pin 300 on the upper surface of the formwork 100 is made of concrete (CON). When the formwork 100 is removed from the concrete (CON) through the curing process, only the insert (M) remains inside the concrete (CON).

At this time, the fixing pin 300 which is located inside the support member 30 is removed together with the formwork 100.

Next, referring to FIG. 4G, the coupler 10, the fixing member 30, the pipe holder 80, and the fastening pin 40 are positioned under the insert M embedded in the concrete CON.

That is, the coupler 10 is positioned toward the lower portion of the insert M to fix the pipe P, the fixing member 60 is positioned below the coupler 10, and the pipe ( The pipe holder 80 is positioned to surround P), and the fastening pin 40 is positioned at one side of the fixing hole 63 of the fixing member 60.

Next, referring to FIG. 4H, the fixing member 60, the pipe holder 80, and the fastening pin 40 are coupled to one end of the coupler 10.

That is, the fixing member 60 is coupled to one end of the coupler 10 by screwing, and the fixing piece 60 of the pipe holder 80 wrapping the pipe P corresponds to the fixing member 60. The pipe holder 80 coupled to the insertion groove 62 and coupled to the insertion groove 62 of the fixing member 60 is fixed to the fastening pin 40.

Referring to Figure 4i, one end of the coupler 10 is coupled to the insert (M) inside.

That is, by coupling one end of the coupler 10 to the insert M, the pipe P is fixed to the ceiling.

On the other hand, in the process of coupling the coupler 10 to the insert (M) embedded in the concrete (CON) as shown in Figure 4i the effect of the coupling holder 50 and the coupler 10 is coupled to Figure 5 and A detailed description with reference to FIG. 6 is as follows.

Figures 5a to 5d is a functional diagram showing the coupling process of the coupling holder and the coupler using the insert, Figure 6 is a cross-sectional view of the plane state showing the II-II line of Figure 5c.

Prior to the description of the operation of the present invention, L1 and L2 are diameters between the end portions and the end portions of the engaging pieces 51 of the coupling holder 50, and L1 and L2 diameters of the outer circumferential surface of the coupler 10 and the fastening grooves 11. It will be described with reference to Figure 4g as needed.

Referring to FIG. 5A, a state before the coupler 10 is coupled into the insert M is shown.

That is, the coupling holder 50 has a diameter L1 between each end and the end of the engaging piece 51 positioned at the left and right sides of the coupling holder 50 smaller than the outer peripheral surface diameter L1 of the coupler 10. It has been achieved. On the other hand, the diameter L1 between the fastening groove 11 diameter of the coupler 10 and each end and the end of the engaging piece 51 of the coupling holder 50 are the same.

Next, referring to FIG. 5B, the engaging piece 51 of the coupling holder 50 is turned back by the coupler 10.

That is, when the coupler 10 is coupled to the inside of the insert M, the engaging piece 51 at the virtual line position is flipped backward while contacting the outer circumferential surface of the coupler 10.

In other words, the diameter L1 between the end and the end of the engaging piece 51 is smaller than the outer diameter L2 of the outer circumferential surface of the coupler 10 so that the coupler 10 is located between the end and the end of the engaging piece 51. When the locking piece 51 is flipped back by the outer diameter (L2) of the coupler (10).

Therefore, the coupler 10 coupled into the insert M is not fully engaged.

Referring to FIG. 5C, the coupler 10 fixed by the coupling holder 50 is fully engaged with the insert M. Referring to FIG.

That is, if the coupler 10 positioned between the end and the end of the engaging piece 51 is continuously pushed upward in the drawing so as to be fully coupled to the insert M, the outer peripheral surface of the coupler 10 and the fastening groove 11 are selectively The locking piece 51 to be positioned is flipped back, and the process of returning to the original position is repeatedly performed.

When the end of the coupler 10 is completely moved to the inside of the upper cap 70 by the above process, the engaging piece 51 is coupled to the fastening groove 11 of the coupler 10. This coupler 10 is fully coupled to the insert (M).

In other words, the diameter L2 between the end and the end of the engaging piece 51 is matched to the outer circumferential surface of the coupler 10 and the diameter of the fastening groove 11.

For example, when the engaging piece 51 is located on the outer circumferential surface of the coupler 10, the coupler 10 is not coupled to the coupling holder 50, and the engaging piece 51 is the fastening groove 11 of the coupler 10. When placed in the coupler 10 is coupled to the coupling holder 50.

Therefore, when the engaging piece 51 is located in the fastening groove 11 of the coupler 10, the coupler 10 is in a state coupled to the insert (M).

In this case, when a load is applied to the coupler 10, the engaging piece 51 holding the coupler 10 also receives a lot of load, which may cause the engaging piece 51 to sag downward. However, since the edge portion 52 of the coupling holder 50 is pressed against the upper cap 70 and the inclined surface 53 is extended in a horizontal state, the coupler 10 is prevented from sagging downward. It is fixed inside the insert M by the coupling holder 50.

Referring to FIG. 5D, the coupler 10 is moved to the lower side inside the insert M. FIG.

That is, when the coupler 10 is rotated in a state in which the engaging piece 51 of the coupling holder 50 is correspondingly coupled to the spiral engaging groove 11 of the coupler 10, the coupler 10 is a spiral engaging piece. The end of the coupler 10 is moved downward by the movement range h1 while being guided by the 51 to rotate in the screw loosening direction.

Therefore, the height of the pipe P is adjusted from the ceiling, and when the coupler 10 is completely detached from the insert M, the end of the coupler 10 interferes with the engaging piece 51 of the coupling holder 50. You can rotate it so that it is not received.

Here, the height adjustment of the pipe (P) from the ceiling and when the coupler 10 is separated from the insert (M), as shown in Figure 4g, the fixing member 30 or the pipe coupled to one end of the coupler 10 The pipe holder 80 fixing (P) is separated from the coupler 10 and then adjusted.
