As shown, the exterior fixing device 20 is the primary fixing member 25, the primary fixing member 25 of the "" "shaped to be detachably fixed to the steel angle 22, the primary fixing member 25 slides downwards. Control plate 21 that can prevent or adjust the height of the primary fixing member 25, the secondary fixing member 30 fixed to one end of the primary fixing member 25, and the interior of the exterior material 37. Buried, it is composed of a buffer case (Shoe Case) 38 to which the secondary fixing member 30 is coupled.

The primary fixing member 25 is in surface contact with the steel angle 22, and the lower portion of the vertical portion 23 and the vertical portion 23, the first through-hole 23a (Fig. 5) is formed at a predetermined position It is bent at a right angle and consists of a horizontal portion 24 having a second through hole 34 formed at its tip.

A pair of non-slip jaws 26 protrude from the upper predetermined position of the vertical portion 23, and the pair of non-slip jaws 26 contact the upper surface of the adjusting plate 21.

The adjusting plate 21 is a rectangular plate, and an inclined groove 27 inclined at a predetermined angle is formed therein. Accordingly, the first fastening screw 28 penetrates the first through hole 23a (Fig. 5) of the inclined groove 27 and the vertical portion 23, and the hole 22a of the steel angle 22 (Fig. 5). The fastening plate 21 and the primary fixing member 25 are integrally fixed to the steel angle 22 by being fastened to the steel plate. At this time, the upper surface of the adjustment plate 21 is in contact with the bottom surface of the pair of non-slip jaw 26 to support, thereby preventing the primary fixing member 25 from sliding downward.

In addition, if the adjusting plate 21 is properly moved laterally, the contact position of the inclined groove 27 and the first fastening screw 28 is changed along the inclined surface, so that the height of the primary fixing member 25 can be adjusted. have.

On the other hand, the secondary fixing member 30 is composed of an upper fastener 29 and a lower fastener 31. One end of the upper fastener 29 is formed with a first through hole 31a (FIG. 5), and the other end is formed with an upper bent portion 32 that is bent upwardly vertically. In addition, a second through hole 29a (Fig. 5) is formed at one end of the lower fastener 31, and the other end is bent vertically downward to form a lower bent portion 33.

Then, the second fastening screw 35 is fastened to the second through hole 34 of the primary fixing member 25 by passing through the first and second through holes 29a and 31a (FIG. 5). 29 and 31 are integrally fixed. Accordingly, the upper and lower fasteners 29 and 31 may be separately assembled and disassembled, the upper fastener 29 supports the vertical load and the wind load, and the lower fastener 31 supports the wind load. In addition, since the first and second through holes 29a and 31a (Fig. 5) are elongated in the horizontal direction, the second fastening screw 35 is moved in the horizontal direction, thereby between the exterior member 37 and the steel angle 22. The distance D1 of FIG. 5 can be adjusted.

The vinyl 36 is sandwiched between the bottom face of the lower fastener 31 and the top face of the horizontal portion 24 of the primary fastening member 25. In general, when materials of dissimilar components come into contact with each other, a potential difference occurs at the contact surface, thereby causing corrosion. Therefore, the non-conductive material such as vinyl is disposed between the lower fastener 31 and the primary fixing member 25 to prevent corrosion.

On the other hand, the packaging material 37 has a rectangular plate shape having a predetermined thickness, and a buffer case 38 is embedded therein. That is, the exterior member 37 is formed with circular grooves 39 of predetermined depths at the upper and lower ends thereof, respectively. The number of the circular grooves 39 may be formed one and a plurality depending on the size of the packaging material (37).

In addition, the buffer case 38 is a plastic material having a predetermined elastic force, and one side surface 38a has a triangular shape and a polyhedron shape in which an empty space is formed. When the shock absorbing case 38 is embedded in the circular groove 39 of the packaging material 37, the filler such as the epoxy 40 is filled between the circular groove 39 and the shock absorbing case 38, whereby the shock absorbing case 38 ) Is fixed to the circular groove (39). At this time, since one side 38a of the shock absorbing case 38 is triangular in shape, it is possible to prevent the shock absorbing case 38 from being pushed in one direction by an external force generated when filling the filler.

After the shock absorbing case 38 is fixed to the exterior material 37, the upper and lower bent portions 32, 33 of the upper and lower fasteners 29, 31 are fitted inside the shock absorbing case 38, respectively. The voids are removed by injecting the caulking material 41 into the buffer case 38. Thus, the upper and lower fasteners 29 and 31 are integrally and elastically fixed inside the shock absorbing case 38.

As described above, the exterior material 37 is fixed to the steel angle 22 by the upper and lower fasteners 29 and 31, and when an external shock is transmitted, the shock is absorbed by the shock absorbing case 38 primarily. Secondly, it is absorbed by the caulking material 41 inside the shock absorbing case 38.

Hereinafter, the construction method of the building exterior material according to the present invention will be described in more detail.

5 and 6, the exterior material construction method is the external circular groove processing step 100, epoxy filling step 200, buffer case mounting step 300, the primary fixing member installation step 400, secondary fixing The member temporary assembly step 500, the exterior material installation step 600, the secondary fixing member assembly step 700, and the finishing treatment step 800, such as sealing.

In the exterior member circular groove processing step 100, the circular groove 39 having a predetermined depth on the upper and lower surfaces of the exterior member 37 is processed. That is, a circular groove 39 having a predetermined curvature is processed using a tool such as a diamond saw, and the foreign matter such as dust is removed from the surface of the processed circular groove 39 by using a high pressure air injector. Therefore, when filling the epoxy 40, it is possible to improve the adhesive force of the epoxy (40).

In the epoxy filling step 200, a predetermined amount of epoxy 40 is filled in the circular groove 39 formed in the previous step. The epoxy 40 plays an appropriate buffer role when the buffer case 38 is embedded. Therefore, when an external force such as wind pressure or vertical load is applied, the external force transmitted to the shock absorbing case 38 is primarily absorbed.

In the buffer case mounting step 300, the buffer case 38, which is separately manufactured, is embedded in the circular groove 39 of the exterior material filled with the epoxy 40. That is, the shock absorbing case 38 is introduced into the epoxy 40 and positioned at the inner center of the circular groove 39 to prevent eccentricity. At this time, since one side 38a of the buffer case 38 is triangular, three points can be supported, thereby preventing the buffer case 38 from being eccentric when the buffer case 38 is embedded and the epoxy 40 is filled. In addition, since the shock absorbing case 38 has a predetermined surface area, when an external force is applied, concentration of stress can be prevented.

After embedding the buffer case 38, the residue of the epoxy 40 leaked to the outside of the circular groove 39 is removed. Then, the curing case 38 is firmly fixed to the exterior material through the curing process.

In the primary fixing member installation step 400, the adjusting plate 21 is brought into contact with the bottom of the pair of non-slip jaws 26, and the first fastening screw 28 is steel plate through the inclined groove 27 and the first through hole. By fastening to the angle 22 for fixing, the primary fixing member 25 is fixed to the angle 22 for steel frames. And, if necessary, the height of the primary fixing member 25 can be adjusted by properly moving the adjustment plate 21 laterally.

In the step of assembling the secondary fixing member 500, the upper and lower fasteners 29 and 31 are integrally fixed to the horizontal portion 24 of the primary fixing member 25 by the second fastening screw 35. At this time, since the upper and lower fasteners 29 and 31 need to be properly adjusted in the process of being embedded in the buffer case 38 of the packaging material, the second fastening screw 35 is temporarily assembled.

In the exterior installation step 600, the bent portion 33 of the upper and lower fasteners 29 and 31 is positioned inside the shock absorbing case 38 of the exterior material. Then, the caulking material 41 having a predetermined elastic force is filled in the shock absorbing case 38. Accordingly, the bent portions 33 of the upper and lower fasteners 29 and 31 are elastically fixed to the interior of the shock absorbing case 38, thereby absorbing external forces such as wind pressure and vertical load.

As a result, the external force acting on the packaging material 37 is primarily absorbed by the epoxy 40 and secondly by the caulking agent 41. Therefore, the exterior material 37 can be stably fixed to the upper and lower fasteners 29 and 31.

In the second fixing member assembly step 700, the upper and lower fasteners 29 and 31 are completely fixed to the inside of the shock absorbing case 38 by the caulking agent 41, and then temporarily assembled into the second through hole 34. The first fastening screw 28 is finally assembled. Accordingly, the exterior material 37 is integrally assembled to the angle 22 for steel frame by the primary and secondary fixing members 25 and 30. At this time, by appropriately moving the second fastening screw 35 in the horizontal direction, it is possible to adjust the distance (D1) between the exterior material 37 and the building outer surface.

In addition, in the finishing process step 800 such as sealing, after the exterior material 37 is assembled, the gap of the exterior material 37 is finished by using a finishing material such as sealant 42. Therefore, by preventing foreign matter such as external rainwater or dust from flowing between the exterior material 37 and the wall surface, corrosion is prevented.

As described above, the building exterior material is stably fixed to the wall surface of the building through the above steps.

As described above, the fixing device and the construction method of the building exterior material according to the present invention have various advantages.

First, since the buffer case is embedded in the interior of the packaging material by epoxy and the caulking material, an appropriate elastic force is generated and the stability of the packaging material is improved by absorbing the external force.

Second, since the surface area of the buffer case is wide, stress can be dispersed to prevent breakage of the exterior member and the fixing member.

Third, since the upper and lower fasteners are separately mounted, it is easy to repair and replace the exterior material.

Fourth, since there is no processing process of the exterior material in the field, only the assembly process is required, the assembly work is easy, and the working time is shortened.

Fifth, by embedding the shock absorbing case in the factory in the factory to be installed in the field, it is possible to increase the precision when assembling the exterior material.
