## Background
TECHNICAL FIELD
The present invention relates to an assembly of prefabricated panels for interior or exterior walls of a building construction, and more particularly to an assembly of prefabricated panels for a building construction which is capable of simply achieving connection of prefabricated panels attached to interior or exterior walls of the building construction, and application of a finish to upper, lower and opposite longitudinal ends of each prefabricated panel.
BACKGROUND ART
As building constructions are exposed to weather conditions such as sunlight, rain and snow, and pollution for a prolonged period of time, their exterior walls may be damaged. In order to repair such damage, a remodeling process may be used.
Also, in the interior of a building construction, decorative and functional panels may be attached to the interior walls of the building construction for repair of damage, display of goods, or remodeling of the interior. For such panels, prefabricated panels may be used which are made of bent metal sheets or aluminum sheets.
Such panels, which have an elongated rectangular structure, are fixed to a wall by means of nails or the like in a state of being vertically stacked in an end-to-end abutted manner.
However, since a number of nails must be used upon fixing such panels to a wall in the above mentioned manner, an installation process is prolonged. Furthermore, where this nailing process is applied to an old building construction, it may greatly damage the building construction.
Moreover, the nails used to fix the panels to the wall of such an old building construction provide paths for allowing rainwater to penetrate into the concrete of the building construction, thereby causing the concrete to be rapidly weakened.
Meanwhile, such panels have a limited length and a limited width for convenience of transportation and workability. For this reason, where these panels are attached to a building construction, they must be overlapped with one another while forming longitudinal junctions at certain intervals. Furthermore, these panels have a drawback in that they have no accessory for finishing the corners and upper/lower ends of the building construction.
Another example of panels configured to be used for the above mentioned purpose is disclosed in Korean Utility Model No. 0134667. This utility model discloses insulating panels for roofs. Each insulating panel is formed, at both longitudinal ends thereof, with inner and outer coupling portions, respectively, so that the insulating panels are serially coupled. Each insulating panel is also provided at upper and lower ends thereof with inwardly-bent portions shaped in such a manner that one bent portion has a size to be fitted around the other bent portion, respectively. Accordingly, adjacent insulating panels can be coupled in accordance with a fitted coupling between the bent portions respectively provided at the facing ends thereof. However, since these insulating panels are made of a material other than metal sheets, and the coupling portions thereof have an insufficient rigidity, they may be bent or separated from one another when an external force is applied thereto.
Although the above mentioned structure is applicable to insulating panels, it cannot be applied to non-insulating panels made of, for example, aluminum or other metal sheets. In the latter case, therefore, it is impossible to eliminate drawbacks caused by the fact that the panels have insufficient strength against an external force applied thereto.

The corner finishing member 20 is coupled with the facing longitudinal ends of prefabricated panels 10 defining a corner region therebetween, by fitting the facing ends of the prefabricated panels 10 between the outer extensions 21 and the associated outer claws 23, respectively. FIG. 5b illustrates a corner finishing member having a structure in which the outer extensions 21 are eliminated from the corner finishing member of FIG. 5a. Although the outer extensions 21 are eliminated, this structure can support the prefabricated panels 10 by the outer claws 23 and the apexes of the inner protrusions 22.
FIG. 6 is a sectional view illustrating a panel connecting member. This panel connecting member is adapted to couple the facing longitudinal ends of two prefabricated panels, that is, the prefabricated panels 10 and 10-2, arranged adjacent to each other while forming a junction therebetween, as indicated by a region “B” in FIG. 3. As shown in FIG. 6, the panel connecting member denoted by the reference numeral 30 has a T-shaped body 31 having a horizontal portion and a vertical portion extending vertically, at one end thereof, from a central position of the horizontal portion, and a pair of coupling claws 32 extending inclinedly outwardly from the other end of the vertical portion in the T-shaped body 31 toward the horizontal portion of the T-shaped body 31 at opposite sides of the vertical portion, respectively. The panel connecting member 30 is coupled with the facing ends of the prefabricated panels 10 and 10-2 by fitting the facing ends of the prefabricated panels 10 and 10-2 between the horizontal portion of the T-shaped body 31 and the associated coupling claws 32, respectively.
FIG. 7 is a sectional view illustrating a longitudinal end finishing member. This longitudinal end finishing member is adapted to finish the longitudinal end of a prefabricated panel 10 exposed at an end region without facing any other prefabricated panel, as indicated by a region “C” in FIG. 3. As shown in FIG. 7, the longitudinal end finishing member denoted by the reference numeral 40 has an inverted L-shaped body 41 having a horizontal portion and a vertical portion, and a coupling claw 42 extending inclinedly from a substantially intermediate position of the vertical portion in the inverted L-shaped body 41 toward the horizontal portion of the inverted L-shaped body 41. The longitudinal end finishing member 40 is fitted around the longitudinal end of the prefabricated panel 10 exposed at the end region.
FIG. 8 is a sectional view illustrating an upper end finishing member. This upper end finishing member is adapted to finish the upper end of an uppermost one of the prefabricated panels 10 attached to the building construction, as indicated by a region “D” in FIG. 4. As shown in FIG. 8, the upper end finishing member denoted by the reference numeral 50 has an S-shaped body having upper and lower bent portions 51 and 13-1, and a coupling claw 52 extending inclinedly inwardly from an outer tip of the upper bent portion 51. The upper end finishing member 50 is coupled with the upper end of the uppermost prefabricated panel 10 by engaging the coupling claw 52 with the rear surface of the uppermost prefabricated panel 10 at the upper end of the uppermost prefabricated panel 10 while fitting the lower bent portion 13-1 in the fitting recess 11 of the uppermost prefabricated panel 10.
FIG. 9 is a sectional view illustrating a lower end finishing member. This lower end finishing member is adapted to finish the lower end of a lowermost one of the prefabricated panels 10 attached to the building construction, as indicated by a region “E” in FIG. 4. As shown in FIG. 9, the lower end finishing member denoted by the reference numeral 60 has an inverted S-shaped body 15-1 having an upper bent portion defining a forwardly-opened coupling recess 11-1, and an engagement protrusion 12-1 upwardly protruded from the upper end of the inverted S-shaped body 15-1 into the coupling recess 11-1 by a desired length. The lower end of the lower end finishing member 60 is rearwardly bent. The lower end finishing member 60 is coupled with the lower end of the lowermost prefabricated panel 10 by fitting the lower bent section 13 of the lowermost prefabricated panel 10 in the coupling recess 11-1.
The prefabricated panels of the present invention are usable not only for the exterior walls of a building construction, but also for the interior walls of the building construction. In particular, where the prefabricated panels are used for the interior walls of the building construction, a display panel mounting member 70 may be coupled with the coupling recess 11 of a selected one of the prefabricated panels in order to mount a display panel 71 for goods to the selected prefabricated panel, as shown in FIG. 10a which is a sectional view illustrating the display panel mounting member coupled to the prefabricated panel.
As shown in FIG. 10a, the display panel mounting member 70 has a hook 72 adapted to be engaged with the engagement protrusion 12 of the prefabricated panel 10 to be coupled with the display panel mounting member 70, a fitting portion 73 for fitting an end of the display panel 71 therein, and a support portion 74 for supporting the end of the display panel 71 fitted in the fitting portion 73. In accordance with this structure, the display panel mounting member 70 can mount the display panel 71 to the prefabricated panel 10 in order to display goods on the display panel 71.
Meanwhile, cabinets or various hangers may be attached to the prefabricated panels 10 using hook members each adapted to be mounted to a cabinet or hanger while being engaged with the engagement protrusion 12 of a selected prefabricated panel 10. FIG. 10b illustrates an example in which a cabinet 80 is mounted to a selected prefabricated panel 10.
FIG. 11 is an exploded perspective view illustrating an assembly of prefabricated panels according to another embodiment of the present invention. FIG. 12 is a partially-cut-out assembled perspective view illustrating an assembly of prefabricated panels according to another embodiment of the present invention modified from the embodiment of FIG. 12. FIGS. 13a to 13j are sectional views illustrating use of various panel assemblies including the panel assembly shown in FIG. 11 or other panel assemblies in which their prefabricated panels are modified from those of FIG. 11 to have various panel body shapes, respectively.
Basically, each of the panel assemblies shown in FIGS. 11, 12, and 13a to 13j includes first brackets 110 adapted to be directly mounted to a wall 100 of the building construction. Each first bracket 110 has a vertically-extending strip structure while being provided with a plurality of hooks 111 arranged in pairs such that the hook pairs are vertically uniformly spaced apart from one another, Bolt holes 112 are also provided at each of the upper and lower end portions in each first bracket 110. The panel assembly also includes second brackets 120 each adapted to be coupled to an associated one of the first brackets 110. Each second bracket 120 has a vertically-extending hollow bar structure while being provided, at a rear wall portion thereof, with a plurality of engagement holes 121 arranged in pairs such that the hole pairs are vertically uniformly spaced apart from one another. Each pair of the engagement holes 121 is adapted to be engaged with an associated pair of the hooks 111 in the associated first bracket 110. Each second bracket 120 is also provided, at a front wall portion thereof, with a plurality of hooks 122 vertically uniformly spaced apart from one another. Each of the prefabricated panels, which are included in the panel assembly, has a panel body 15, an upper bent section extending from an upper end of the panel body 15 while being rearwardly and upwardly bent, a first engagement protrusion 12 upwardly protruded from the upper end of the panel body 15 while defining a coupling recess 11 in cooperation with the upper bent section, and a second engagement protrusion 19 downwardly protruded from the lower end of the bent section, and adapted to be engaged with an associated one of the hooks 122 in the second bracket 120. Each prefabricated panel also has a lower bent section 13 extending from a rear surface of the panel body 15 near a lower end of the panel body 15 while being rearwardly and downwardly bent. The prefabricated panels are vertically aligned while being coupled to one another such a manner that the lower bent section 13 of the upper prefabricated panel 10 is fitted in the coupling recess 11 of the lower prefabricated panel 10-1, as shown in FIG. 11. The second bracket 120 may be dispensed with. In this case, the second engagement protrusion 19 is engaged with an associated pair of the hooks 111 in the first bracket 110.
In the drawings, the reference numeral 80 denotes a cabinet, 100 a building wall, 101 an intermediate bracket, and 102 nails.
Now, the procedure for assembling the constituting elements of the panel assembly according to each embodiment of the present invention will be described in detail with reference to the drawings.
FIG. 2 is a sectional view illustrating an assembled state of the prefabricated panels included in the panel assembly according to one embodiment of the present invention. FIG. 3 is a sectional view illustrating an application of the panel assembly. FIG. 4 is a sectional view illustrating another application of the panel assembly.
The panel assembly of the present invention may be used when it is desired to remodel an old building construction for protection and repair of the building construction, by attaching the prefabricated panels 10 of the panel assembly to an exterior wall of the building construction in a state of being vertically stacked along the exterior wall in an end-to-end abutted manner.
That is, one prefabricated panel 10 is first attached to a lower end portion of the exterior wall, and then nailed on the lower wall end portion at its coupling recess 11, so that it is firmly fixed to the exterior wall, as shown in FIG. 2. Although the prefabricated panel 10 is nailed to an intermediate bracket 101 in the case of FIG. 2, it will be described as being nailed to the exterior wall of the building construction in the following description for convenience.
Thereafter, another prefabricated panel 10 is stacked on the fixed, lower prefabricated panel 10 in an end-to-end abutted manner. At this time, the coupling of the upper and lower prefabricated panels 10 can be achieved by inserting the lower bent section 13 of the upper prefabricated panel 10 into the coupling recess 11 of the lower prefabricated panel 10, and then downwardly pushing the lower bent section 13 along the coupling recess 11 until the lower end of the lower bent section 13 comes into contact with the bottom of the coupling recess 11. In this state, the lower bent section 13 of the upper prefabricated panel 10 is firmly fitted in the coupling recess 11 of the lower prefabricated panel 10 in a state of being engaged, at its lower end, with the engagement protrusion 12 of the upper prefabricated panel 10.
In such a manner, a plurality of prefabricated panels can be vertically assembled to cover the entire wall portion of the building construction.
However, the prefabricated panels have a limited length for convenience of manufacture, transportation, storage, and workability. For this reason, they must also be longitudinally assembled to cover the entire wall portion of the building construction. In this case, the longitudinally-adjacent prefabricated panels, for example, the prefabricated panels 10 and 10-2, are connected by the panel connecting member 30 of FIG. 6.
The panel connecting member 30, which has a T-shaped structure as shown in FIG. 6, is interposed between the facing longitudinal ends of the longitudinally-adjacent prefabricated panels 10 and 10-2, and coupled with the facing longitudinal ends of the prefabricated panels 10 and 10-2 by forcibly fitting the facing longitudinal ends of the prefabricated panels 10 and 10-2 between the horizontal portion of the T-shaped body 31 and the associated coupling claws 32, respectively, while covering a junction of the facing longitudinal ends by the horizontal portion of the T-shaped body 31.
Accordingly, it is possible to prevent foreign matters such as rainwater or dust from penetrating into the junction while providing a satisfactory decorative finish.
On the other hand, the corner finishing member 20 shown in FIG. 5a or 5b is used at a corner where the front and side wall portions of the building construction are connected.
That is, in the case of FIG. 5a, the corner finishing member 20 is coupled with the facing longitudinal ends of prefabricated panels 10 defining a corner region therebetween, by forcibly fitting the facing longitudinal ends of the prefabricated panels 10 between the outer extensions 21 and the associated outer claws 23, respectively, while covering a space defined between the facing longitudinal ends. Accordingly, it is possible to prevent foreign matters from penetrating into the junction while providing a satisfactory decorative finish. In the case of FIG. 5b in which the outer extensions 21 are dispensed with, the prefabricated panels 10 may be supported by the outer claws 23 and the apexes of the inner protrusions 22.
Where it is desired to finish the longitudinal end of a prefabricated panel 10 exposed at an end region, the longitudinal end finishing member 40 of FIG. 7 having an inverted L-shaped structure is used. The longitudinal end finishing member 40 is coupled with the longitudinal end of the prefabricated panel 10 exposed at the end region by fitting the longitudinal end of the prefabricated panel 10 between the horizontal portion of the L-shaped body 41 and the coupling claw 42. Accordingly, the longitudinal end of the prefabricated panel 10 is covered by the longitudinal end finishing member 40.
Where it is desired to finish the upper end of an uppermost one of the prefabricated panels 10 attached to the building construction, the upper end finishing member of FIG. 8 having an S-shaped structure is used. The upper end finishing member 50 is coupled with the upper end of the uppermost prefabricated panel 10 by fitting the lower bent portion 13-1 in the fitting recess 11 of the uppermost prefabricated panel 10 while engaging the coupling claw 52 with the rear surface of the uppermost prefabricated panel 10 at the upper end of the uppermost prefabricated panel 10.
Accordingly, the upper end of the prefabricated panel 10 is covered by the longitudinal end finishing member 40, so that it is smartly finished.
Where the lower end portion of a building construction wall is to be finished, it is desirable to first attach the lower end finishing member 60 of FIG. 9 to the lower wall end portion.
That is, the lower end finishing member 60 is first fixed to the lower end portion of the building construction wall at the coupling recess 11-1 thereof by means of nails. Thereafter, the lower bent section 13 of a prefabricated panel 10 is fitted in the coupling recess 11-1 of the lower end finishing member 60. Thus, the prefabricated panel 10 is coupled to the lower end finishing member 60. Since the lower end finishing member 60 has a small width, it maintains a sufficient firmness by the fixing means. Also, the lower end finishing member 60 provides a decorative finish because it covers the lower end portion of the building construction wall by its body 15-1.
The prefabricated panels of the present invention are usable not only for the exterior walls of a building construction, but also for the interior walls of the building construction. In particular, where the prefabricated panels are used for the interior walls of the building construction, the display panel mounting member 70 may be coupled with the coupling recess 11 of a selected one of the prefabricated panels in order to mount a display panel for goods or a decorative cabinet to the selected prefabricated panel.
As described above, the display panel mounting member 70 has the hook 72 adapted to be engaged with the engagement protrusion 12 of the prefabricated panel 10 to be coupled with the display panel mounting member 70, the fitting portion 73 for fitting an end of the display panel 71 therein, and the support portion 74 for supporting the end of the display panel 71 fitted in the fitting portion 73. In accordance with this structure, the display panel mounting member 70 can be conveniently used in that it can be coupled to and separated from the prefabricated panel 10 by simply engaging the hook 72 with the engagement protrusion 12 and simply disengaging the hook 72 from the engagement protrusion 12. Also, the display panel mounting member 70 can provide an enhanced display effect for goods in that it can support a wide display panel.
The panel assembly of FIG. 11 or 12 may also be used. As described above, FIG. 11 is an exploded perspective view illustrating an assembly of prefabricated panels according to the embodiment of the present invention different from that of FIG. 1. FIG. 12 is a partially-cut-out assembled perspective view illustrating the assembly of prefabricated panels according to the embodiment of the present invention modified from the embodiment of FIG. 12. In either case of FIG. 11 or 12, each first bracket 110 is first mounted to the wall 100 of the building construction by means of the bolt holes 112 provided at each of the upper and lower end portions in the first bracket 110. As described above, the first bracket 110 has the hooks 111 arranged in pairs such that the hook pairs are vertically uniformly spaced apart from one another. Each second bracket 120 is then coupled to the associated first bracket 110 by engaging each pair of its engagement holes 121 with an associated pair of the hooks 111 in the associated first bracket 110. As described above, each second bracket 120 is provided, at the front wall portion thereof, with the hooks 122 vertically uniformly spaced apart from one another.
Prefabricated panels are coupled to respective hooks 122 of the second bracket 120. Each prefabricated panel may have the panel body 15, the upwardly-protruded first engagement protrusion 12 upwardly protruded from the upper end of the panel body 15, and the downwardly-protruded second engagement protrusion 19. The second engagement protrusion 19 of the prefabricated panel is engaged with an associated one of the hooks 122 in the second bracket 120. In such a manner, the prefabricated panels are sequentially coupled to the second bracket 120 so that they are vertically aligned. Thus, the prefabricated panels decoratively cover the outer or interior wall of the building construction.
The prefabricated panels can be attached to the building construction wall while being spaced apart from the building wall by a certain distance in accordance with use of both the first bracket 10 and the second bracket 120. Of course, the attachment of the prefabricated panels may be achieved in a state in which the second bracket 120 is dispensed with. In this case, it is possible to minimize the space between each prefabricated panel and the building construction wall.
Thus, it is possible to use both the first bracket and the second bracket or to use a selected one of them.
