Hereinafter, referring to FIGS. 1 to 4, the stone 3, in front of the wall 1 in which the heat insulator 2 is constructed on the front surface using the stone fixing device 10 for building exterior according to the first embodiment of the present invention, will be described. We explain how to construct 4).

The worker drills the heat insulating material 2 and the wall 1, inserts the stone fixing device 10 of the present invention into the drilling hole of the heat insulating material 2, and then the rear end of the stone fixing device 10, that is, the support piece ( When hitting the rear end of the 150, the fixing unit A is inserted into the perforation hole h of the wall 1 and the fixing unit A is fixed to the perforation hole of the wall 1. At this time, the extended support bar 140 is a form inserted through the heat insulating material 2, the support piece 150 is a shape protruding to the outside of the heat insulating material (2).

On the other hand, when the present invention is drilled in the heat insulating material 2 and the wall (1), the size of the drilling hole is formed to be the same or slightly smaller than the thickness of the extension support bar 140.

In the above description, the fixing unit A is fixed to the perforation hole of the wall 1 in detail. When the fixing unit A is inserted into the perforation hole h of the wall 1, the wedge-shaped anchor is inserted. The sleeve 130 is inserted into the perforated hole (h) of the wall (1), the wedge-shaped anchor sleeve 130 is reduced in diameter and tightened while pressing the anchor body 120 tightly, the anchor sleeve ( The fixing protrusion 134 and the auxiliary fixing protrusion 136 of 130 are fixed to the perforation hole of the wall 1, so that the fixing unit A is fixed to the perforation hole h of the wall 1 and stably fixed. Will remain intact.

Then, in the state in which the stone fixing device 10 of the present invention is fixed to the wall (1), by inserting the coupling pin (p) into the pin insertion hole 153, the coupling groove formed in the lower end of the upper stone ( Insert the upper portion of the coupling pin (p) to 3a), and insert the lower portion of the coupling pin (p) into the coupling groove (4a) formed in the upper end of the lower stone (4) support piece It can be installed so as to be supported by 150.

In the stone fixing device 10 of the present invention, the anchor body 120, the extension support bar 140, and the support piece 150 are integrally formed, so that the fixing unit A has a perforation hole h of the wall 1. In the settled state), the extension support bar 140 and the support piece 150 are not shaken or rattled with respect to the fixing unit A, thereby enabling stable installation of the

stones

3 and 4.

In addition, since the present invention has a structure in which the fixing unit A is stably settled in the perforation hole h of the wall 1 by hitting the rear end of the support piece 150, it is difficult for the worker to hold it by hand as in the past. You can do it easily without having to turn around.

In addition, the present invention, the construction of the stone (3, 4), the support piece 150 should be maintained in a horizontal state, after fixing the fixing unit (A), the support piece 150 is not horizontal and slightly inclined In this case, by gently tapping one side of the support piece 150, the anchor body 120 is easily rotated by a predetermined angle with respect to the wedge-shaped anchor sleeve 130, thereby easily adjusting the horizontality of the support piece 150 Stone (3, 4) can be constructed.

The present invention is drilled into the heat insulating material (2) and the wall (1) in the same or somewhat smaller size than the diameter of the extension support bar 140, and inserted into the drilled hole (h) formed, and extends from the constructed structure Since a space does not occur between the support bar 140 and the heat insulator 2, it is possible to secure the overall heat insulation without the need to fill a separate heat insulator.

On the other hand, the present invention has been described in the fixing the slab (3, 4) by fixing the fixing unit (A) to the wall (1) in which the heat insulating material (2) is installed on the front, the present invention is the heat insulating material (2) the front It is also possible to fix the wall in the same manner as described above to construct a slab.

Hereinafter, referring to FIGS. 5 to 9, a building exterior stone fixing device 10 ′ according to a second embodiment of the present invention will be described.

In the first embodiment, the rear end of the support piece 150 is hit, and the fixing unit A is inserted into the perforation hole h of the wall 1 to fix the rear end of the support piece 150 too strongly. When hitting the support piece 150 is crushed and deformed, it may be somewhat difficult to properly install the stone (3, 4) on the support piece 150 in accordance with the horizontal design to fit the construction design position.

Thus, the second embodiment of the present invention is configured to further include a striking auxiliary member 160 to strike the rear end of the extended support bar 140, without directly hitting the support piece 150.

The second embodiment differs only in that it further includes the hitting aid member 160 compared to the first embodiment, and the rest of the configuration is the same as that of the first embodiment, so only the differences will be described.

5 to 7, the striking assisting member 160 includes a striking body 162 and a bit 166 detachably screwed to the rear end of the striking body 162.

An insertion groove 163 into which the support piece 150 is inserted is formed at the front of the hitting body 162, and the female threaded portion 164 is integrally formed at the rear end thereof.

In the present embodiment, the thickness of the insertion groove 163 may be configured to be slightly larger than or slightly the same as the thickness of the support piece 150. However, even when the thickness of the insertion groove 163 is configured to be larger than the thickness of the support piece 150 is configured to be smaller than the diameter of the extended support bar 140. In addition, the length of the insertion groove 163 of the present invention is configured to be larger than the front and rear length of the support piece 150.

Therefore, as shown in Figure 9, when the support piece 150 is inserted into the insertion groove 163, the front end surface of the striking body 162 is caught by the inclined surface 145 of the extended support bar 140, it is no longer inserted, In this state, the rear end of the support piece 150 is spaced apart without touching the inner end of the insertion groove 163.

Bit portion 166 is formed in a bar shape that can be fixed to the bite chuck (c, Fig. 8) of the power tool (e, see Fig. 8), such as a hammer drill. The front end of the bit portion 166 is integrally formed with a male threaded portion 167 for screwing into the female threaded portion 164, so that the bited portion 166 may be screwed into the rear end of the striking body 162.

Hereinafter, referring to FIGS. 5 to 9, the stone 3 in front of the wall 1 in which the heat insulator 2 is constructed on the front surface using the stone fixing device 10 for the building exterior according to the second embodiment of the present invention. We explain how to construct 4).

First, the worker drills the heat insulating material 2 and the wall 1 in the same manner as in the first embodiment to form a hole for drilling.

Thereafter, as shown in FIG. 8, the operator inserts the support piece 150 into the insertion groove 163 of the striking assist member 160, and moves the bit part 166 of the striking assist member 160 to the power tool e. The fixing unit (A) of the stone fixing device (10) and the extension support bar (140) are inserted into the drilling holes of the heat insulating material (2), and the power tool (e) is driven. In this case, the front surface of the striking body 162 of the striking assist member 160 does not strike the support piece 150, but rather hits the rear end of the extended support bar 140, that is, the inclined surface 145, thereby fixing unit (A). The fixing unit A is fixed to the perforation hole h of the wall 1 while being inserted into the perforation hole h of the wall 1. At this time, the extended support bar 140 is a form inserted through the heat insulating material 2, the support piece 150 is a shape protruding to the outside of the heat insulating material (2).

Thereafter, after separating the striking assist member 160 from the support piece 150, in the same manner as in the first embodiment in a state in which the support piece 150 protrudes out of the heat insulating material 2, as shown in FIG. The plywood pin (p) may be inserted into the pin insertion hole 153 and installed to support the upper stone 3 and the lower stone 4 on the support piece.

As such, the present invention does not hit the support piece 150 in a state in which the support member 150 is mounted on the power tool e, and the support piece 150 is inserted into the blow aid member 160. By hitting the rear end of the extended support bar 140, since the fixing unit A is fixed to the wall 1, no deformation of the support piece 150 is crushed, and the flat original state of the support piece 150 is not generated. It can be maintained as it is, makes it easy to install the installation spacing of the slabs uniformly according to the construction position.

In addition, since the striking assistance member 160 of the present invention has a structure in which the striking body 162 and the bit part 166 can be detachably fastened to each other, the striking body 162 of the support bar 140 is extended. When broken or damaged in the process of hitting the rear end, that is, the inclined surface 145, replace only the striking body 162 with a new one can be used by re-fastening the existing bit portion 166, on the contrary, the bit portion 166 Even when it is damaged, the existing blow body 162 can be used by replacing only the bit part 166 without leaving it. That is, the striking assist member 160 of the present invention is a structure in which the striking body 162 and the bit portion 166 are formed in a modular form, respectively, used to be fastened to each other. In case of damage, only damaged parts can be replaced with new ones, which reduces the cost of construction.

While the present invention has been described as having a female threaded portion 162 formed on the striking body 162 and a male threaded portion 167 integrally formed on the bit portion 166, the present invention is not limited thereto. Of course, the male threaded portion may be formed at (), and the female threaded portion may be formed at the bit portion (166).

In addition, the bit portion 166 of the present invention may be made of the same material as the bit used to be inserted into a conventional power tool, the striking body 162 may be made of a stainless material or other metal material.

The invention has been shown and described in connection with the preferred embodiments for illustrating the principles of the invention, but the invention is not limited to the configuration and operation as shown and described. Rather, those skilled in the art will appreciate that many changes and modifications can be made to the present invention without departing from the spirit and scope of the appended claims. Accordingly, all such suitable changes, modifications, and equivalents should be considered to be within the scope of the present invention.
