DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a fixing structure of a building exterior material and a fixing material construction method according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a sectional view of a fixing structure of a building exterior material according to an embodiment of the present invention, and FIG. 2 is an exploded view of a fixing structure of a building exterior material according to an embodiment of the present invention.

As shown in FIGS. 1 and 2, a fixing structure A of a building exterior material according to an embodiment of the present invention includes an anchor 100 coupled to a building structure 10, and an anchor 100 A nut 300 coupled to an end of the anchor 100 to fix the bracket 200 to the building structure 10 and a bracket 200 coupled to the anchor 100 to support the bracket 200. [ A packing member 400 installed between the engaging portions of the bracket 200 to prevent heat transfer between the anchor 100 and the bracket 200 and an end portion of the anchor 100 and the nut 300 And a heat bridge cap 500 for preventing heat transfer through the end of the anchor 100 and the nut 300.

The building structure 10 may be a column or a wall forming the skeleton of the building.

A set anchor or a wedge anchor may be used as the anchor 100 to be coupled to the building structure 10, but in the present embodiment, a set anchor is used as the anchor 100. However, it does not exclude the use of wedge anchors and the like.

The anchor 100 includes an anchor bolt 110 having a body portion 111 having a predetermined radius and a head portion 112 formed at an end portion of the body portion 111 and having a conically shaped head portion 112, The anchor cap 120 is screwed to the body portion 111 of the anchor bolt 110 and the anchor bolt 110 is screwed to the anchor bolt 110 And a tightening nut 130 for extending one end of the anchor cap 120 in the radial direction through a pressing action of the head 112 of the anchor cap 120.

At this time, the anchor bolt 110 and the anchor cap 120 may be formed of zinc-plated metal or stainless steel so as not to rust with strength.

A thread 170 is formed on the body 111 of the anchor bolt 110 and the head 112 is formed in a conical shape at an end of the body 111. In this way, the formed anchor bolt 110 is fitted to the anchor cap 120. The anchor cap 120 is formed with a cutout 121. Therefore, the end side of the anchor cap 120 on which the incision 121 is formed can be opened.

A tightening nut 130 is screwed to the body portion 111 of the anchor bolt 110 and the tightening nut 130 can be tightened along the thread 170. Accordingly, when the tightening nut 130 is tightened, the anchoring bolt 110, which is transported by the tightening action of the tightening nut 130, 120 is opened. The anchor bolt 110 is inserted into the anchor installation hole 11 formed in the building structure 10 and then the anchor cap 120 is opened by tightening the tightening nut 130. As a result, Are firmly fixed to the building structure 10 or the like.

A tightening nut washer 140 and a spring washer 150 may be installed between the anchor cap 120 and the tightening nut 130 to tighten the tightening nut 130 when the tightening nut 130 is tightened.

At this time, the tightening nut 130, the tightening nut washer 140, and the spring washer 150 may be omitted when the bracket 300 is closely attached to the building structure 10.

A part of the head part 112 and the body part 111 of the anchor bolt 110 are inserted into the anchor installation hole 11 formed in the building structure 10.

As described above, the anchor 100 is fitted in the anchor mounting hole 11 before the anchor 100 is inserted into the anchor mounting hole 11, and is provided with a thermal bridge 30 for blocking the thermal bridge through the anchor 100.

The heat bridge 30 is for blocking heat transmitted to the building structure 10 through the anchor 100 and is filled in the anchor installation hole 11 and then is inserted into the anchor installation hole 11 And the anchor 100, as shown in Fig.

For this purpose, the thermal bridge member 30 filled in the anchor mounting hole 11 may be a resin which is filled in the anchor mounting hole 11 and solidified to exhibit heat insulating performance. As the resin to be filled in the anchor mounting hole 11, silicone, urethane or the like can be used.

In addition, a resin 160 molded to be integrated with the insert injection-molded anchor 100 may be provided to prevent heat from being transmitted to the building structure 10 through the anchor bolts 110.

As the resin 160, a resin 160 such as urethane or fiber reinforced plastic (FRP) may be used. The thermal conductivity of the resin 160, such as urethane, is much lower than that of a metal material such as stainless steel. Therefore, if the anchor bolt 110 is wrapped with the resin 160, heat conduction through the anchor bolt 110 can be prevented.

The resin 160 preferably covers the body portion 111 and a part of the head portion 112 inserted into the building structure 10 in the anchor bolt 110.

As described above, the heat flow blocking material 30 in the anchor mounting hole 11 and the resin 160 provided in the anchor bolt 110 block the heat flowing toward the building structure 10 through the anchor 100. Therefore, the energy loss of the building can be reduced. Also, it is possible to prevent the condensation phenomenon from occurring in the building by preventing the heat bridge.

Meanwhile, the bracket 200 is formed of a metal material and has a generally "A" shape. Only one bracket may be used to support the building exterior material, but brackets 200 may be used in combination if a plurality of brackets are needed.

Although not shown in the drawing, a heat insulating cover (not shown) may be provided to enclose the bracket 200 to block heat conduction through the metallic bracket 200.

Accordingly, external heat transmitted to the bracket 200 can be prevented from being transmitted to the interior of the building structure 10 through the anchor 100.

The anchor 100 extends from the seating part 510 and is exposed to the outside of the nut 300. The anchor 100 may be formed of a synthetic resin, And a space portion 520 in which the end of the gasket 520 is located.

The mounting part 510 is formed such that a nut 300 fastened to the anchor 100 is inserted into the thermal bridge cap 500 so that one surface of the packing member 400 corresponding to one surface of the thermal bridge cap 500 So that they do not come into contact with each other.

The end of the anchor 100 exposed to the opposite side of the tightening direction of the nut 300 may be positioned in the space 520 after the nut 300 is fastened and tightened. Therefore, it is possible to provide a clearance space for adjusting the length of the anchor 100 according to circumstances.

Since the ends of the nut 300 and the anchor 100 are cut off from the outside by the provision of the heat bridge cap 500 as described above, the external heat is transmitted through the ends of the nut 300 and the anchor 100 to the building structure 10, Can be prevented.

Meanwhile, the washer 330 may be provided on the anchor 100 before the nut 300 is fastened.
