More particularly, the present invention relates to a method for constructing a building exterior material using a pull-out bracket, and more particularly, to a method of constructing a building exterior material by reinforcing a fixing structure of a building exterior material when the exterior wall of the building is constructed, The present invention also relates to a method of constructing a building exterior material using the building exterior material fixing device and a method of constructing the exterior material using the building bracket, which is capable of maintaining a fixed structure of the building exterior material for a long period of time.

Generally, in a building such as a house or an apartment, a wall structure is formed by pouring concrete. In order to finish and decorate the outer wall of the wall structure, a panel type building exterior material such as marble or natural stone and an ALC block is used.

In order to construct such exterior materials, various external sizes of building exterior materials are installed continuously along the horizontal and vertical directions on the wall structure, and a fixing device is installed to fix the position of each building exterior material. .

Recently, in order to improve the heat insulation performance due to the heat loss of the building, a heat insulation material made of various materials such as polyurethane foam or foamed polystyrene is required to be installed between the wall structure and the exterior material.

As a conventional technique disclosed in relation to a fixing device for a building exterior material as described above, Korean Patent Registration No. 606647 (July 24, 2006) discloses a floor panel comprising a height control plate formed of a vertical plate and a horizontal plate, An anchor bolt which is buried in a wall surface through a slot of the vertical plate and is fastened to the wall by fixing the height regulating plate to the wall surface and an interval formed by the slot and fastened by the height regulating plate to the fastening bolt and the fastening nut through the slot of the horizontal plate And a connecting pin inserted into the pin hole of the gap adjusting plate and having an end inserted into the connecting groove of the stone, wherein the height adjusting plate includes a fixing pin facing rearward on the back surface of each corner of the vertical plate, And thus it is possible to reduce the time and cost required to install the stone, Lt; / RTI >

Also, Korean Patent Registration No. 1532703 (Jun. 26, 2015) discloses a fixing unit in which a position is fixed on a wall; And a supporting unit for supporting a building stone disposed in front of the wall, the supporting unit having a structure linearly extending rearward from the fixing unit, wherein the supporting unit comprises: a supporting member positioned at a side of a joining portion of the building stone; And a joining member coupled to the coupling portion of the building stone in a state of being coupled with the support member, wherein the supporting unit is connected to the fixing unit so as to be rotatable about an axis in the forward and backward direction, Is disposed eccentrically with respect to the center of rotation of the supporting unit and is displaced in accordance with the rotation angle of the supporting unit, thereby improving the workability and preventing construction defects.

However, in the case of the above-mentioned conventional arts, the installation structure of the fixing device is complicated due to the large mounting area of the fixing device due to the joining structure of the L-shaped height control plate and the plate-shaped interval control plate, A large hole is required to be opened on the heat insulating material by the occupied area of the fixing device, and the part of the heat insulating material that has been opened must be refilled.

In addition, in the case of the above-mentioned conventional technique, only one portion of the wall structure, which is contacted by the fixing unit, is buried on the wall structure, and only the thickness of the heat insulating material is fixed. Therefore, if an external force acts in the horizontal direction from the outside to the fixing device, a clearance capable of moving the fixing device occurs, causing a shaking phenomenon and a deflection phenomenon caused by a load applied in the vertical direction. There was a problem of being exposed to danger.

The set anchor part 10 is provided on the wall structure 3 for fixing the building exterior 7 as shown in Fig. 1 and is composed of an anchor bolt 11 and an anchor cap 17 .

As shown in FIG. 2, the anchor bolt 11 is fixed at one end on the wall structure 3 and extends in the longitudinal direction from the wall structure 3 forward.

And a fixing end portion 13 is provided at the rear of the anchor bolt 11. That is, the fixing end portion 13 is embedded on the wall structure 3, so that the anchor bolt 11 can be fixed.

Since the fixing end portion 13 is formed on the outer periphery of the peripheral surface of the anchor bolt 11 in an outward direction to form the inclined supporting surface 14 having a larger diameter than the anchor cap 17, As shown in Fig.

The inclined surface 14 of the fixing end portion 13 is inclined at an angle of 10 to 15 degrees toward the outer periphery with respect to the anchor bolt 11 so that the anchor cap 17 can be easily expanded .

The anchor cap 17 and the anchor cap 17 are formed integrally with the anchor cap 17 and the anchor cap 17. The anchor cap 17 and the anchor cap 17 are integrally formed with the anchor cap 17, It is possible to minimize the friction area at the time of the contact with the sliding surface, thereby achieving a smooth sliding action.

Since the anchor cap 17 has the receiving hole H penetrating in the longitudinal direction so as to receive the anchor bolt 11 inside the anchor cap 17, It is possible to maintain the state.

The reinforcement support 31 of the second embodiment of the present invention in which the base plate 32 is formed together with the support tube 33 and the reinforcement plate 35 in the case of the drawing bracket 30 is used.

(6) In the fixing head unit 20 mounting step S60, the fixing head unit 20 is fixed to one end of the fastening part 15 of the anchor bolt 11.

(7) Insulating material (5) In the filling step (S70), the heat insulating material scrap (6) cored in the step (3) is fitted into the heat insulating material (5) again.

The heat insulating material scrap 6 applies the heat insulating material scrap 6 obtained through the integrated composite working bit 40 as it is.

In the case of the cutting portion where the drill 41 or the cutting bit 45 of the integrated composite processing bit 40 is touched during the processing, the gap of the cutting portion is filled due to the inherent elasticity and buffering property of the heat insulating material 5.

(8) In the installing step (S80) of the building exterior 7, the building exterior 7 is brought into contact with the fixed head unit 20, but is fixed by fixing pins.

That is, according to the present invention, since the drawing bracket for supporting and supporting the anchor bolts of the set anchor portion is constructed, according to the construction exterior material fixing device having the drawer bracket according to the present invention and the building exterior material construction method using the same, It is possible to prevent the shaking of the anchor bolt due to the external force acting on the anchor bolt, to prevent the shaking of the anchor bolt, to prevent the sagging phenomenon of the building exterior from the load toward the vertical direction, to improve the structural stability and construction quality of the exterior casing, It is possible to extend the service life.

In addition, the present invention simplifies the installation structure for a fixing device of a building exterior material, secures a sufficient working space, combines a core structure and a heat insulating material, It is possible to drastically shorten the construction air.

While the preferred embodiments of the present invention have been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the present invention.
