The present invention relates to a fixing structure of a building exterior material, and more particularly to a building exterior material which can prevent heat loss, reduce energy loss of a building, prevent condensation, and perform a role as a passive house To a fixed structure.

Generally, anchors such as set anchors are mainly used as a means for fixing a building exterior material such as stone to a building structure.

The set anchor includes an anchor bolt having a thread formed at one end thereof and a head portion whose other end is conically shaped as in " Korean Patent Laid-Open Publication No. 10-2012-0035976 (2012.04.17) ", and a cylindrical anchor bolt An anchor cap comprising: an anchor cap to which an anchor bolt is fitted, the anchor cap having a side incision, and an anchor bolt threadedly connected to the anchor bolt, And a tightening nut that flares in the radial direction from the origin.

The set anchor is inserted into an anchor mounting hole drilled on a wall surface of a set anchor, which is a pair of the anchor cap, the anchor bolt and the tightening nut, and tightening action of the tightening nut fastened to the anchor bolt The anchor bolt is projected to the outside of the wall surface, and one end of the anchor cap corresponding to the head of the anchor bolt is raised in the radial direction from the incline by the pressing action of the head portion of the inclined and enlarged anchor bolt And is completely fixed to the outer wall of the building.

Meanwhile, recently, as the cost of fossil fuel such as coal and oil has rapidly increased, there is an increasing interest in passive houses that can minimize energy waste in designing and building buildings. In other words, a passive house is a building that keeps the room temperature properly without using fossil fuel by blocking heat from the building to the outside as much as possible. Various types of thermal barrier materials have been developed for this purpose, and attempts have been made to use the thermal barrier materials as the exterior materials of buildings. However, even if the building is constructed using the exterior material of the building having increased heat shielding efficiency, when the conventional fixing means as described above is used, heat loss to the outside due to the fixing means is generated, The problem has still been raised.

On the other hand, in order to improve the insulation performance of the building, insulation material is installed inside the exterior material of the building.

Therefore, when fixing the exterior material of the building to the exterior wall of the building, it is necessary to install the insulation material on the outer wall when the concrete is laid or to insulate the insulation material with the adhesive or the fixing pin, then cut off the installation part of the anchor bolt, Such as a bracket.

However, since the metal anchor bolts are installed using fixing means such as brackets, the heat insulating material is damaged and a finishing process is required. In addition, the heat from the outside of the building is transferred to the set anchor and the bracket, .

In addition, when metal anchor bolts and brackets are used, it takes a lot of time to install the exterior material of the building.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems and it is an object of the present invention to provide a fixing structure of a building exterior material which can prevent energy loss of a building, prevent condensation, and act as a passive house, will be.
