Referring to the assembly and construction process of the building insert (1) of the present invention configured as described above are as follows.

First, looking at the assembly process of the building insert (1) of the present invention, the coupling holder 30 is inserted into the inner seating portion 3 of the support member (10). At this time, the anti-rotation groove 37 formed on one side of the coupling holder 30 is matched to the anti-rotation bar 17 of the support member 10, the outer circumferential surface of the coupling holder 30 of the polygonal shape It corresponds to the inner side. As a result, the coupling holder 30 positioned at the seating portion 13 of the support member 10 is fixed in a state in which it does not move in either direction (see FIG. 4).

Next, the upper cap 50 for pressing and fixing the upper surface of the support ring 33 of the coupling holder so that the coupling holder 30 positioned in the seating part 13 does not deviate from the seating part 13. ) Is coupled to the support member 10 inside.

That is, the fitting part 51 formed on one side of the upper cap 50 is matched with the anti-rotation bar 17 of the support member 10. Subsequently, when the upper cap 50 is pushed into the supporting member 10, the locking protrusion 57 formed on the upper cap 50 is engaged with the locking groove 19 of the supporting member 10. . Accordingly, the coupling holder 30 is pressed and fixed to the lower end portion of the upper cap 50 by the seating portion 13 of the support member 10 (see FIG. 5).

Here, since the inner surface of the pillar portion 12 of the support member 10 and the outer circumferential surface of the upper cap 50 are combined in a cross-sectional polygonal shape, the upper cap 50 moves inside the support member 10. Is not.

Another coupling of the upper cap 50 inside the support member 10 is the iron portion formed on the outer circumferential surface of the upper cap 50 on the yaw portion 16 formed on the inner surface of the pillar portion 12. (52) may combine together mutually.

In the present invention, the engaging function between the engaging groove 19 of the support member 10 and the engaging projection 57 of the upper cap 50 and the yaw portion 16 and the upper cap of the support member 10 ( Coupling function between the iron portion 52 of 50) is shown together in FIG. 3, but may have only one function.

On the other hand, if you look briefly at the construction process according to the embedding of the building insert (1) inside the concrete (CON), a fixing pin (not shown) is fixed to the upper surface of the formwork (not shown), the upper surface of the formwork The support member 10 is fixed to surround the fixed pin. Next, the coupling holder 30 is inserted into the support member 10 fixed to the mold upper surface, and the upper cap 50 is coupled to the support member 10 to fix the coupling holder 30. Next, when the concrete (CON) is poured into the formwork, and after the concrete (CON) curing, the formwork is removed from the concrete (CON) together with the fixing pin, only the building insert (1) remains inside the concrete (CON). .

One end of the coupler 70 is coupled to the building insert 1 embedded in the concrete CON through the construction process through the through hole 14 of the support member 10, and then the At the other end, a pipe holder 80 for supporting the pipe pipe P is fixed with the help of the fixing member 90 (see FIG. 3).

Here, the configuration of the coupler 70 is a helical fastening groove 71 is formed on the outer circumferential surface so that a portion of the coupler 70 is coupled to the coupling holder 30 provided inside the building insert 1, The insertion portion 73 is formed by a plurality of annular rims 75 protruding from each other, and a plurality of rotating pieces 77 in a crisscross direction on the outer circumferential surface of the portion bordering the fastening groove 71 and the annular rim 75. ) Is formed.

The configuration of the pipe holder 80 is rotated around the hinge pin 81 and the band portion 83 is formed to surround the pipe pipe (P), each end of the band portion 83 is fixed piece (for convenience "pair" 85 "is formed. The outer circumferential surface of the pair of fixing pieces 85 is formed to have a smaller diameter toward the upper side, and grooves 85a and 85b are formed on the inner side of the pair of fixing portions 85 and the annular rims 75. The locking jaw 87 is formed at an upper side of the outer circumferential surface of the pair of fixing pieces 85 to prevent the fixing member 90 coupled to the pair of fixing pieces 85 from being separated.

The fixing member 90 has an inner circumferential surface corresponding to the pair of fixing pieces 85 so that the fixing piece 85 does not open in a state in which the insertion portion 73 and the annular frame 75 are wrapped. It is formed to be tapered, and the rotary knob 91 is formed to face the outer circumferential surface.

The fixing of the pipe pipe P through mutual coupling of the coupler 70, the pipe holder 80, the fixing member 90, and the like will be described with reference to FIGS. 3, 7A, and 7B. 1) At a lower end portion of the coupler 70 having one end fixed in advance, the band portion 83 surrounding the pipe pipe P is rotated about the hinge pin 81, so that the pair of fixing pieces 85 face each other. Make it look Next, the insertion portion 73 of the coupler 70 has a groove 85a portion surrounding the insertion portion 73, and the annular rim 75 has a groove 85b portion surrounding the annular rim 75. Let it hang

Next, the fixing member 90 is coupled to the outer circumferential surface of the pair of fixing pieces 85 so that the pair of fixing pieces 85 do not open in contact with each other.

Here, the diameter of the side in which the engaging jaw 87 is formed in the pair of fixing pieces 85 is large when the pair of fixing pieces 85 and the fixing member 90 are coupled to each other. Therefore, the fixing member 90 may also be coupled in a direction to match the diameter of the side on which the locking step 87 is formed.

Next, by coupling the fixing member 90 to the pair of fixing pieces 85, the pair of fixing pieces 85 do not open. This does not occur by the wedge action between the pair of fixing pieces 85 that are opened under the influence of the load of the piping pipe P between the fixing members 90 (see FIG. 7A). However, the fixing member 90 may be removed from the pair of fixing pieces 85 by an external force. In order to prevent this, when the rotary knob 91 formed on the outer circumferential surface of the fixing member 90 is rotated in the direction shown by the arrow shown in FIG. 7A, a portion having a smaller diameter among the inner diameters of the fixing member 90 may be formed. The locking jaw 87 formed on the pair of fixing pieces 85 is caught. For this reason, the fixing member 90 is not separated from the fixed state of the pair of fixing pieces 85 (see FIG. 7B).

When removing the pipe holder 80 from the coupler 70 supporting the pipe pipe P, a portion of the inner diameter of the fixing member 90 having a larger diameter is used for the pair of fixing pieces 85. Rotates while holding the rotary knob 91 of the fixing member 90 to match the locking jaw (87). Then, the fixing member 90 can be easily separated from the pair of fixing pieces 85, and the pair of inserts 73 and the annular rim 75 of the coupler 70 are enclosed. Since the fixing piece 85 can be separated from the coupler 70, the pipe holder 80 can be removed from the pipe pipe P that is fixed to the ceiling.

Meanwhile, the interaction between the coupling holder 30 according to the coupling of the coupler 70 inside the building insert M embedded in the concrete CON will be described with reference to FIGS. 3 to 6.

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 31 of the coupling holder 30, and L1 and L2 diameters of the outer circumferential surface of the coupler 70 and the fastening grooves 71. to be. Here, the outer circumferential surface of the coupler 70 is a screw thread located between the fastening grooves 71, and for convenience, the outer circumferential surface is referred to as a screw thread 79. Therefore, the diameter L1 between each end and the end of the engaging piece 31 positioned on the left and right sides of the coupling holder 30 is smaller than the outer diameter ℓ1 of the outer circumferential surface of the coupler 70, and the coupler The diameter L1 between the fastening groove 71 diameter 70 of the fastening groove 71 and each end of the engaging piece 31 of the coupling holder 30 is the same.

First, in the process of coupling the coupler 70 into the building insert 1, the coupler 70 may be interfered with the engaging piece 31 of the coupling holder 30.

That is, when the coupler 70 is forced into the support member 10, the engaging pieces 31 of the coupling holder 30 are pushed back against the threads 79 of the coupler 70. do. The engaging pieces 31 of the coupling holder 30 pushed backward by the thread 79 of the coupler 70 are flipped back by the one-dot chain line shown in FIG. 6 by their elasticity.

In other words, when a forced entry of the coupler 70 into the building insert 1 is performed, the diameter L1 between the end and the end of the engaging piece 31 is the diameter of the thread 79 of the coupler 70 ( Less than L2). Therefore, when the coupler 70 is positioned between the end and the end of the engaging piece 31, the engaging pieces 31 are inclined backward by the diameter of the thread 79 of the coupler 70. Thus, the coupler 70 is not completely coupled inside the building insert 1.

Here, when the engaging pieces 31 are folded back, the inlet portion of the inner insertion hole 53 of the upper cap 50 holding the upper portion of the support ring 33 of the coupling holder 30 on the inclined surface G Is not interfered with.

When the forced entry of the coupler 70 into the building insert 1 stops, the engaging piece 31 of the coupling holder 30 is self-elastic in the state of being positioned as a dashed line shown in FIG. 6. It is caught by the fastening groove 71 of the coupler 70 while being returned to its original state.

In other words, the diameter (L2) between the end and the end of the engaging piece 31 is in a state of matching the outer peripheral surface of the coupler 70 and the diameter of the fastening groove (71). Thus, the coupler 70 is in a state fully coupled to the building insert (1).

Through the entry of the coupler 70 as described above, the engaging pieces 31 of the coupling holder 30 are flipped to the rear, and then the coupler 70 into the support member 10 through the process of being returned to its original state. ) Is combined.

When a load is applied to the coupler 70, a lot of load is applied to the engaging pieces 31 that hold the coupler 70. As a result, the locking pieces 31 may be struck downward. However, since the bending preventing portion 15 of the support member 10 supports the locking pieces 31, the locking pieces 31 are not struck downward.

For example, when forcibly pulling and removing the coupler 70 coupled to the building insert 1, the engaging pieces 31 coupled to the fastening groove 71 of the coupler 70 to be inclined upward are bent. The coupler 70 cannot be forcibly removed from the building insert 1 because it is not bent under the support of the prevention part 15.

In order to remove the coupler 70 from the support member 10, the rotating piece 77 formed in the crosswise direction on the coupler 70 may be rotated in a screw release direction. For example, when the coupler 70 is rotated in the screw release direction, the position of the fastening groove 71 of the coupler 70 coupled to correspond to the engaging piece 31 of the coupling holder 30 is the position of the coupler 70. The rotary piece 77 is moved downward in accordance with the rotational speed.

In other words, when the position of the coupling groove 71 of the coupler 70 moves downward in the helical direction while being guided by the locking pieces 31, the coupler 70 completely moves away from the locking pieces 31. Is removed from the support member (10).

Here, the coupling holder 30 supporting the coupler 70 may move in the same direction as the rotation direction of the coupler 70. However, the outer circumferential surface of the coupling holder 30 corresponds to the polygonal surface 11 of the support member 10, and the anti-rotation groove 37 corresponds to the anti-rotation bar 17 of the support member 10. The coupler 70 is rotated only in the state in which the coupling holder 30 is fixed inside the support member 10.

Therefore, the height adjustment of the pipe pipe P from the ceiling is made as follows by the interaction between the coupler 70 and the coupling holder 30 as described above. That is, in a state in which the coupler 70 is inserted into the support member 10 and fixed in the one-touch manner, when the rotating piece 77 of the coupler 70 is rotated in the screw loosening direction or the screw locking direction, the spiral coupler 70 rotates in the spiral direction. As the position of the fastening groove 71 of the coupler 70 guided by the engaging pieces 31 is changed, the distance between the ceiling and the pipe pipe P is adjusted.

On the other hand, another embodiment of the coupling holder of the present invention will be described with reference to FIG.

Referring to these drawings, a plurality of engaging pieces 31 extending on the inner circumferential surface of the support ring 33 is inclined upward toward the center of the support ring 33, and a line connecting the ends of the engaging pieces 31 is spiraled. A portion of the support ring 33 is formed to be gradient so that the heights of the ends of the engaging pieces 31 are different from each other, and the engaging piece 31 is not formed in the gradient section P. In addition, one side of the support ring 33 is formed with a rotation preventing groove 31 coupled with the anti-rotation bar 17, the outer peripheral surface may be formed to correspond to the inner polygonal surface 11 of the support member 10. Do. Therefore, when used in the support member 10 seating portion 13 is made in the same manner as described above will be omitted accordingly.
