Referring to Figure 4, the construction method of the installation structure (A) according to the present embodiment, including a fixing step (S100), a fixing material application step (S200), a sheet attachment step (S300), and a finishing material application step (S400) can do.

The fixing step (S100) is a step of arranging the body 100 along the tube 9 and fixing the body 100 to the wall 2. Specifically, after placing the tube 9 in the mounting hole 110 formed in the body 100, the anchor bolt 500 is placed in the buried portion 130 of the extension 120 formed at the front end of the body 100 By fastening, the body 100 can be fixed to the wall 2.

After the fixing step (S100), a fixing material applying step (S200) of applying the fixing material 200 to the outer surface of the body 100 may be performed. Here, the fixing material applying step (S200) may include fixing the body 100 to the wall 2 and then filling the fixing material 200 in the buried part 130.

After the fixing material applying step (S200), a sheet attaching step (S300) of attaching the sheet 300 made of a fiber-reinforced material to the outer surface of the body 100 may be performed. In addition, after the sheet attaching step (S300), a finishing material applying step (S400) of applying and finishing the finishing material 400 to the outside of the sheet 300 may be performed.

In the fixing material applying step (S200) and the finishing material applying step (S400), the fixing material 200 and the finishing material 400 may be used, respectively. As described above, the fixing material 200 and the finishing material 400 may be formed of a binder or a bonding material having excellent heat resistance and adhesion.

The installation structure (A) through the fixing step (S100) to the finishing material application step (S400) as described above can minimize the exposure of the anchor bolts 500 fixing the body 100 to the wall 2 to the outside. have. Accordingly, when a fire occurs, the anchor bolt 500 may be melted and damaged due to high temperature heat, or a secondary accident may be prevented due to separation of the tube body 9 to the power line 6 supported thereto.

In some cases, the construction method of this embodiment may further include a blasting process step.

The blasting processing step may include sandblasting the outer surface of the body 100 before the fixing step S100 to form a fine uneven surface on the outer surface of the body 100. Accordingly, the contact area between the outer surface of the body 100 and the sheet 300 is increased, and the sheet 300 can be more firmly attached to the outer surface of the body 100.

According to the installation structure (A) or the construction method according to the present invention as described above, the body 100 and the anchor bolt 500 fixing the tube 9 to the power line 6 to the wall 2 have excellent heat resistance. It may be properly shielded from external heat by the fixing material 200 and the finishing material 400. Accordingly, it is possible to effectively prevent the body 100 or the anchor bolt 500 from being damaged by the high temperature heat generated in the event of a fire, and to prevent a secondary accident due to the separation of the pipe body 9 to the power line 6 I can.

In addition, according to the installation structure (A) or construction method according to the present invention, a sheet 300 made of a fiber-reinforced material may be positioned between the fixing material 200 and the finishing material 400, and in this state, the sheet 300 It may serve to hold the fixing material 200 and the finishing material 400. Accordingly, damage of the fixing material 200 and the finishing material 400 due to thermal expansion may be prevented to a certain degree, and the tube body 9 may be prevented from falling off from the wall 2 due to the high temperature heat generated in the event of a fire. I can.

5 is a cross-sectional view schematically showing a power line installation structure of an apartment house according to a second embodiment of the present invention.

Referring to FIG. 5, the power line installation structure (hereinafter referred to as "installation structure (A1)") of an apartment house according to this embodiment may additionally be provided with sensor means for notifying an alarm when a fire occurs. .

Specifically, the installation structure A1 of this embodiment is formed in the same or similar to the first embodiment described above, but a piezoelectric element 610 may be added between the body 100 and the finishing material 400.

The piezoelectric element 610 may be electrically connected to the wireless communication module 620, and the wireless communication module 700 may wirelessly communicate with the notification means 630 provided outside the installation structure A1. The notification means 630 may be any one capable of providing an alarm signal in a form that is identifiable by the user, such as visual or audio, and may include, for example, a buzzer.

As is known, the piezoelectric element 610 may generate electric polarization according to an external mechanical force or pressure. In this embodiment, the piezoelectric element 610 may be used between the body 100 and the finishing material 400 to detect a pressure change according to the expansion of the finishing material 400. For example, when a fire occurs, the finishing material 400 may be expanded by high temperature heat, and accordingly, the piezoelectric element 610 may be pressurized and a pressure change may be sensed.

The installation structure (A1) of this embodiment detects the pressure change of the piezoelectric element 610 as described above, it is possible to appropriately determine whether the expansion of the finishing material 400 or the occurrence of fire or high temperature, and to transmit the alarm to the outside. And so on.

In particular, in the installation structure A1 of the present embodiment, the piezoelectric element 610 is disposed between the finishing material 400 and the body 100, so that it may not be directly exposed to the outside. Accordingly, even when a fire occurs, the piezoelectric element 610 may not be directly exposed to high-temperature heat, and damage of the piezoelectric element 610 due to heat may be partially prevented. This can contribute to improving the reliability of alarm operation at relatively low cost.

6 is a cross-sectional view schematically showing a power line installation structure of an apartment house according to a third embodiment of the present invention.

6, the power line installation structure (hereinafter, referred to as “installation structure (A2)”) of the apartment house according to this embodiment is formed in the same or similar to the first embodiment described above, but the buried part 130 The shape of -1) can be changed.

Specifically, the buried part 130-1 of the present embodiment may be formed in the shape of a groove recessed in the rear of the body 100. Here, the buried part 130-1 may have a first width W1 at the front end and a second width W2 at the rear end. The front end of the buried portion 130-1 refers to one end of the buried portion 130-1 facing the wall 2, and the rear end of the buried portion 130-1 is the buried portion 130-1 facing the sheet 300. Refers to the opposite end of ).

In the above, the first width W1 may be formed to be larger than the second width W2 by a predetermined degree. For example, the first width W1 may be formed to be 10 to 30% larger than the second width W2. The second width W2 may correspond to the diameter of the head of the anchor bolt 500 or may be formed to be slightly larger than the diameter in consideration of the fastening of the anchor bolt 500.

Due to the difference between the first and second widths W1 and W2, a support surface 131-1 may be formed at the edge of the buried part 130-1. The support surface 131-1 may be defined as a surface supporting rear separation of the fixing member 200 disposed in the buried part 130-1. The support surface 131-1 may be disposed to be inclined by a predetermined angle with respect to the front-rear direction, or may be formed as a surface substantially perpendicular to the front-rear direction. In the case of this embodiment, as in the former, the case where the support surface 131-1 is formed as an inclined surface is illustrated. For reference, the latter case is illustrated in FIG. 7.

The shape of the buried portion 130-1 as described above can appropriately limit the separation of the fixing member 200 impregnated with the buried portion 130-1 and the sheet 300 supported by the fixing member 200. That is, the external force to the rear acting on the sheet 300 may be supported by the support surface (131-1). Accordingly, the sheet 300 or the like may be more firmly attached to the rear of the body 100 and maintained.

In particular, the shape of the buried part 130-1 as described above may be effective in attaching and maintaining the sheet 300 even after a considerable period of time has passed after construction. For example, even if shrinkage deformation occurs in the fixing material 200 after a considerable period of time has passed or the hardened fixing material 200 is partially removed, the sheet through the mechanical shape of the fixing material 200 filled in the buried part 130-1 300, etc. can be held attached. Accordingly, even after a long period of time, the heat blocking effect due to the sheet 300 or the like may be maintained.

7 is a cross-sectional view schematically showing a power line installation structure of an apartment house according to a fourth embodiment of the present invention.

Referring to FIG. 7, the power line installation structure (hereinafter, referred to as “installation structure (A3)”) of an apartment house according to the present embodiment includes a buried part 130-2 similar to the third embodiment described above. However, the specific shape of the buried part 130-2 may be partially changed.

Specifically, in the buried part 130-2 of the present embodiment, the first width W1 of the front end may be formed to be larger than the second width W2 of the rear end by a predetermined degree, and accordingly, the support surface 131-2 Can be provided. The support surface 131-2 may have the same or similar function as the support surface 131-1 of the above-described embodiment. However, unlike the above-described embodiment, the support surface 131-2 of this embodiment is illustrated as a surface that is substantially orthogonal to the front-rear direction.

According to the difference between the first and second widths (W1, W2), the first boundary line 131-2 at the front end of the buried part 130-2 is the second boundary line 13 2-at the rear end of the burying unit 130-2. It may have a radius larger than 2). The second boundary line 132-2 may be generally disposed inside the first boundary line 131-2, and the head of the anchor bolt 500 is generally disposed inside the second boundary line 132-2. I can.

If necessary, the present embodiment may further include an injection path 132-2.

The injection path 132-2 is a front end side of the buried part 130-2 (that is, the space between the first boundary line 131-2 and the second boundary line 132-2), and the fixing material 200 is It can be assisted to ensure smooth entry. Alternatively, the injection path 132-2 may guide the inflow of the fixing material 200 to the front end side of the buried part 130-2.

The injection path 132-2 is formed to extend a predetermined length from the rear of the body 100 to the front, so that the rear end may communicate with the buried part 130-2. The location where the injection path 132-2 communicates is generally intended as a space between the first boundary line 131-2 and the second boundary line 132-2.

Preferably, the injection path 132-2 may be disposed between the first boundary line 131-2 and the second boundary line 132-2 at the rear of the body 100. In this case, the injection path 132-2 is formed in a direction orthogonal to the rear of the body 100, and the injection path is formed into the space between the first boundary line 131-2 and the second boundary line 132-2. (132-2) can communicate. This enables a smooth inflow of the fixing material 200.

The injection path 132-2 may be formed to extend a predetermined length vertically on the rear surface of the body 100. More preferably, the injection path 132-2 may be formed to extend in an arc shape. As shown, the injection path 132-2 of the present embodiment is illustrated in an arc shape disposed in a generally vertical direction.

The injection path 132-2 extending up and down allows the inflow of the fixing material 200 through the injection path 132-2 to be smoothly performed. This may function more effectively in that the installation structure A3 of the present embodiment is installed on the wall 2, not on the floor, ceiling, or the like. That is, after the body 100 is installed on the wall 2, when the fixing material 200 is applied to the outer surface of the body 100, a partial section (eg, the upper section) of the injection path 132-2 extending vertically is Through the fixing material 200 is introduced into the buried portion 130-2, air (bubbles) is discharged through the remaining section (eg, the lower section), the inflow of the fixing material 200 can be made smoothly.

If necessary, a plurality of injection paths 132-2 may be provided, and a plurality of injection paths 132-2 may be spaced apart from the buried part 130-2. In the case of the present embodiment, a case in which a pair of injection paths 132-2 are arranged left and right with the head of the buried part 130-2 or the anchor bolt 500 is illustrated. However, the number and arrangement of the injection paths 132-2 may be variously changed as necessary, and are not necessarily limited to those illustrated.

The injection path 132-2 as described above allows the fixing member 200 to sufficiently flow into the buried portion 130-2 when the fixing member 200 is applied to the body 100. That is, the fixing material 200 may be introduced into the buried portion 130-2 through not only the opening at the rear end of the buried portion 130-2, but also through the injection path 132-2 around the buried portion 130-2. Accordingly, although the second width W2 into which the fixing material 200 is introduced is formed smaller than the first width W1 on the inside, the fixing material 200 can sufficiently flow into the buried part 130-2. have.

Due to the above, a sufficient amount of the fixing material 200 is introduced and hardened between the first and second boundary lines 131-2 and 132-2 inside the buried part 130-2, and the fixing material 200 or the sheet ( 300) can be supported. The fixing member 200 remaining in the injection path 133-2 is also hardened, so that the fixing member 200 or the sheet 300 may be supported. Accordingly, separation of the fixing member 200 or the sheet 300 by the first width W1 may be prevented more effectively.

In the above, embodiments of the present invention have been described, but those of ordinary skill in the art will add, change, delete or add components within the scope not departing from the spirit of the present invention described in the claims. Various modifications and changes can be made to the present invention by means of the like, and it will be said that this is also included within the scope of the present invention.
