Description

Fixing device for installation of exterior panel for building and Exterior panel structure

The present invention relates to an exterior panel for construction, and more particularly, it is possible to reduce the heating and cooling load of a building by maintaining a stable coupling state of the exterior panel to the support pipe and blocking the thermal path between the exterior panel and the support pipe. It relates to a fixing device for installing an exterior panel and an exterior panel structure.

The exterior wall finishing work included in the building construction process is a construction of covering the exterior wall of a building using an exterior panel in a state in which the frame including the wall of the building is completed to some extent. There are various types of exterior panels used for exterior wall finishing, and recently, a light light metal exterior panel has been widely used.

In order to construct such an exterior panel, a method of fixing the steel structure in the form of a square pipe to the outside of the wall of a building first, and then fixing the exterior panel to the steel structure by welding is mainly used. However, the conventional welding fixing method described above is very inconvenient in that welding itself is very inconvenient, and when the vertical or horizontal alignment of the exterior panel is not properly aligned, the welding part must be completely removed and welded again. Due to these problems, the number of cases in which a non-welding construction method is applied is gradually increasing in recent years.

However, in the case of the exterior panel structure constructed by the conventional welding method as well as the non-welding construction method, the consideration of blocking heat conduction between the exterior panel and the steel structure is not taken into account, so that the heat of the exterior panel is directly transferred to the steel structure. have The heat from the exterior panel heated by the hot sun can pass through the steel structure to the building.

Hereinafter, one embodiment according to the present invention will be described in more detail with reference to the accompanying drawings.

1 is an exploded perspective view of an exterior panel structure 10 to which a fixing device 30 for installation of an exterior panel according to an embodiment of the present invention is applied, and FIG. 2 is a perspective view illustrating the exterior panel structure when viewed from another angle. In addition, FIG. 3 is a view showing the exterior panel of FIG. 1 separately, FIG. 4 is a view showing a state in which the fixing device according to an embodiment of the present invention is installed on the support pipe, and FIG. It is a cross section. In addition, FIG. 6 is an exploded perspective view of a fixing device according to an embodiment of the present invention, and FIGS. 7A, 7B, and 7C are views for explaining a mounting method of the exterior panel 40 to the fixing device 30 .

As shown, the exterior panel structure 10 according to the present embodiment includes a plurality of support pipes 20 , a fixing device 30 mounted to each support pipe 20 , and a support pipe through the fixing device 30 . It has a basic structure of the exterior panel (40) supported on (20).

The support pipe 20 is a square pipe that is disposed on the outer wall of the building and is fixed perpendicularly to the ground, and has a holder 21 integrally in the front. The front in this description means the direction opposite to the side facing the building.

The holder 21 provides a guide passage 21a that is opened forward through the slit 21b. The slit 21b has a predetermined width and passes through the male screw portion 33b of the bolt 33 as shown in FIG. 5 . The head portion (33a) of the bolt (33) can be positioned along the longitudinal direction of the support pipe (20) in a state locked in the guide passage (21a). Both sides of the slit 21b are separation prevention covers 21d. The separation prevention cover 21d blocks the head portion 33a from passing through the slit.

The support pipe 20 having such a configuration is disposed on the outer wall of the building, parallel to each other and spaced apart from each other, and is covered by a plurality of exterior panels 40 so as not to be seen from the outside. The support pipe 20 forms the overall load-bearing structure of the exterior panel structure 10 .

On the other hand, the fixing device 30 serves to hang and fix the exterior panel 40 in a state in which it is slidably installed on the holder 21 . The fixing device 30 includes a link bracket 31 , a bolt 33 , a nut 34 , and a heat conduction blocking member 36 .

The link bracket 31 is a steel material taking the shape of a substantially rectangular frame, as shown in FIG. 6 . In other words, it has a shape in which a rectangular pipe is cut short in the longitudinal direction. The length (L) of the link bracket (31) is shorter than the width (W). However, if necessary, the length (L) may be manufactured longer than the width (W).

The link bracket 31 is provided with a close contact portion 31c and a hanger portion 31f. The close contact portion 31c has a bolt hole 31d in the center as a portion that faces the separation prevention cover 21d. In addition, the hanger portion 31f is spaced parallel to the close contact portion 31c and has an insertion hole 31g. The insertion hole 31g is a hole through which a tool (not shown) for tightening the nut 34 passes. The space 31a between the close contact part 31c and the hanger part 31f is a space into which the locking part 43c is inserted into the exterior panel 40 side.

The bolt 33 is coupled with the nut 34 after the head portion 33a is accommodated in the guide passage 21a, and the male screw portion 33b passes upward through the slit 21b and the bolt hole 31d. The nut 34 is screwed with the bolt 33 in the space portion 31a, so that the link bracket 31 is in close contact with the separation prevention cover 21d. That is, by coupling with the bolt, the link bracket acts to be closely fixed to the holder part by the reaction force according to the screw coupling. For coupling of the nut 34 to the bolt 33, a socket wrench (not shown) is passed downward through the insertion hole 31g.

The heat conduction blocking member 36 is molded and manufactured from a heat-resistant synthetic resin, has a predetermined thickness, and has inward grooves 36a at both ends. The inward groove 36a is a groove for receiving both ends of the hanger part 31f in the longitudinal direction. The heat conduction blocking member 36 is elastically deformable by an external force.

The heat conduction blocking member 36 covers the hanger part 31f and prevents the exterior panel 40 supported by the hanger part 31f from coming into direct contact with the link bracket 31 . That is, by floating the exterior panel 40 from the link bracket 31, heat is prevented from being conducted from the exterior panel to the link bracket. Transmission of the heat of the exterior panel 40 heated by the solar heat to the support pipe 20 in summer is suppressed. If there is no heat conduction blocking member 36, heat is transmitted to the support pipe 20, and the heat of the support pipe is usually conducted to the building.

The exterior panel 40 is formed by pressing an iron plate having a predetermined thickness, and has the structure of FIG. 3 . As shown in FIG. 3 , the exterior panel 40 includes a body part 41 in the form of a square plate and a side wall part 42 bent at four edges of the body part 41 . In addition, coupling portions 43 are formed on the left and right sidewall portions 42 of the main body portion 41 up and down. As shown in FIG. 7A , the coupling part 43 corresponds to the fixing device 30 on a one-to-one basis and is a part fixed by being caught by the fixing device 30 .

The coupling portion 43 includes a retaining groove 43b and a locking portion 43c. The holding groove 43b is a groove for accommodating the fixing device 30 . In addition, the engaging portion 43c is a portion extending into the inner region of the retaining groove 43b and is fitted into the space portion 31a of the link bracket 31 . By hooking and fixing the engaging portion 43c to the link bracket 31 , the mounting of the exterior panel 40 to the support pipe 20 is completed. The interlocking portions 43c of the adjacent exterior panels 40 are fitted together in one space portion 31a, thereby maintaining a distance between them.

The coupling of the exterior panel 40 to the support pipe 20 is made as shown in FIGS. 7A to 7C .

7A and 7B, by moving the exterior panel 40 in the arrow a direction in a state where the coupling part 43 is positioned in front of the fixing device 30, the fixing device 30 is in the holding groove (43b) to be inserted. Then, the exterior panel 40 is lowered in the direction of the arrow b of FIG. 7B so that the engaging portion 43c is fitted into the space portion 31a. (See Fig. 7c) At this time, the inner portion of the holding groove (43b) is only in contact with the heat conduction blocking member (36), and is spaced apart from the link bracket (31). In addition, the exterior panel 40 is also spaced apart from the support pipe 20 at regular intervals.

The spacing of the exterior panel 40 with respect to the support pipe 20 can be adjusted by designing the spacing between the close contact part 31c and the hanger part 31f in the link bracket 31 .

8 is a cut-out exploded perspective view for explaining a modified example of the fixing device 30 for installing an exterior panel according to an embodiment of the present invention, and FIG. 9 is a diagram for explaining the function of the fixing device shown in FIG. 8 .

Hereinafter, the same reference numerals as the above reference numerals indicate the same members having the same functions.

Referring to the drawings, it can be seen that the toothed strip 23 is mounted on the upper surface of the separation prevention cover 21d of the holder 21 . The toothed strip 23 has a certain width and thickness, is spaced apart from each other in parallel with the slit 21b therebetween, and meshes with the toothed portion 32a of the toothed plate 32 as shown in FIG. 9 .

In order to couple the toothed strip 23 on the separation prevention cover 21d, a plurality of female threaded holes 21f are formed in the separation prevention cover 21d, and a through hole 23a is formed in the toothed strip 23 . After each through hole 23a is aligned with the female screw hole 21f, the fastening screw 24 is screwed into the female screw hole 21f through the through hole 23a, so that the toothed strip for the support pipe 20 is (23) is mounted.

In addition, the toothed plate 32 is mounted on the bottom surface of the contact portion 31c. The toothed plate 32 provides a toothed portion 32a as a plate-like member corresponding to the toothed strip 23 . The coupling of the toothed plate 32 to the link bracket 31 is possible by bonding or bolting.

As described above, by applying the toothed strip 23 and the toothed plate 32 , the coupling of the fixing device 30 to the support pipe 20 can be maintained more strongly. That is, as shown in FIG. 9 , since the toothed portions 23c and 32a facing each other are engaged, there is no fear that the fixing device 30 slides downward even if a strong vertical load, impact or vibration is applied.

In addition, a center hole 36c is formed in the central portion of the heat conduction blocking member 36 shown in FIG. 8 . The center hole 36c is a through hole coincident with the insertion hole 31g, through which a tool for tightening the nut 34 passes. In addition, a locking protrusion 36d is formed on the bottom surface of the heat conduction blocking member 36 to be inserted into the insertion hole 31g to prevent the relative movement of the heat conduction blocking member with respect to the hanger portion 31f.

10 is a perspective view illustrating another modified example of the fixing device 30 for installing an exterior panel according to an embodiment of the present invention.

As shown, the fixing device 30 according to another modified example has a tilting prevention block 45 on the lower side of the link bracket 31 . The tilt prevention block 45 is linked to the link bracket 31 through the torsion hinge 31k.

The torsion hinge 31k has a built-in torsion spring 31h and is integrally formed with the lower end of the contact part, and rotatably supports the connecting hinge 45h. The connecting hinge 45h is a part of the tilting prevention block 45 and is rotatable in the direction of the arrow s or the opposite direction by using the connecting pin 31m as a rotational center axis while being inserted into the torsion hinge 31k.

As described above, the tilt prevention block 45 is linked to the link bracket via the torsion hinge, and is elastically biased in the arrow s direction by the action of the torsion hinge 31k. The arrow s direction is the direction in which the guide passage 21a is located.

The tilt prevention block 45 is a substantially hexahedral member and has a width k that can pass between the slits 21b. The width of the tilting prevention block 45 may be smaller than the slit 21k width (m) by 1 mm or less. That is, the difference between the width of the tilting prevention block 45 and the width of the slit 21k is 1 mm or less.

The tilt prevention block 45 is partially inserted between the slits, and serves to prevent inclination of the link bracket 31 due to an eccentric load (applied to the link bracket 31). That is, to prevent the link bracket 31 from rotating in the direction of the arrow t or the opposite direction with respect to the z-axis.

As described above, since two adjacent exterior panels 40 are supported by one fixing device 30 , the weight of the adjacent exterior panels is different, or one exterior panel 40 is mounted first and the remaining exterior panels The link bracket 31 may be tilted by the eccentric load applied before the panel is mounted. The tilt prevention block prevents this phenomenon.

Locking projections 45f are formed on both sides of the tilt prevention block 45 . The locking protrusion 45f is caught on the upper surface of the separation prevention cover 21d, and blocks the tilting prevention block 45 from completely falling into the guide passage 21a.

11 is a perspective view showing another modified example of the fixing device 30 for installing an exterior panel according to an embodiment of the present invention, and FIG. 12 is a side view of the fixing device shown in FIG. 11 . Also, FIG. 13 is a view for explaining a method of using the fixing device of FIG. 11 .

The anti-tilt block 45 shown in FIGS. 11 to 13 provides multi-stage side portions 45m having mutually different widths (approximately taking the shape of a step). The reason why the multi-stage side part 45m is applied to the tilt prevention block 45 is to be universally used in the holder 21 having various slit 21b widths.

That is, even if the width of the slit 21b formed in the holder 21 is different, tilting of the link bracket 31 can be prevented with one tilting prevention block 45 . In other words, when the width of the slit 21b is narrow, the narrow side portion 45m is sandwiched between the slits, and when the width of the slit 21b is wide, the wide side portion 45m is sandwiched between the slits. will be.

In addition, the bottom surface of the tilting prevention block 45 is provided with a curved surface portion (45n). The curved portion 45b is a portion curved toward the torsion hinge 31k, and as shown in FIG. 13, even if the tilting prevention block 45 is tilted upward, the side portion 45m is located between the slits 21b. It is designed to be stable.

No matter which side part 45m of the plurality of multi-stage side parts 45m is inserted between the slits 21b, the tilt prevention block 45 is always elastically supported in the arrow s direction by the torsion hinge 31k. do.

As mentioned above, although the present invention has been described in detail through specific embodiments, the present invention is not limited to the above embodiments, and various modifications are possible by those of ordinary skill within the scope of the technical spirit of the present invention.
