Description

Technology Field

[0001] The present invention relates to an exterior building panel, and more specifically, to a metal exterior building panel with improved seismic performance incorporating a movable bracket, which not only increases productivity by facilitating manufacturing but also ensures that the installation state remains stable even in situations such as earthquakes or typhoons by improving seismic and wind pressure resistance performance through support provided by the reinforcing member, and further enhances seismic performance by enabling multi-directional movement via the movable bracket while connected to a frame placed on the exterior wall of a building, thereby absorbing shock. Background Technology

[0002] Since exterior walls and facades of buildings are typically made of concrete or blocks, the aesthetic appeal may be diminished if they are left exposed.

[0003] For this reason, the exterior walls of a building, etc., are covered with a finishing material, namely an 'exterior panel' as disclosed in Korean Registered Patent Publication No. 10-2250859, etc., to make the exterior appearance beautiful.

[0004] At that time, there was a problem in that it was not easy to directly attach exterior panels to the exterior walls of buildings made of concrete or blocks, as they were not only very sturdy but also flat.

[0005] For this reason, a grid-shaped frame formed by the connection of vertical and horizontal sections is placed on the front of the exterior wall of the building, and then exterior material panels are attached to the front of the frame; more specifically, exterior material panels are attached between one of the horizontal sections of the frame and another horizontal section adjacent to its lower portion.

[0006] Installing exterior panels using a frame in this manner makes the work easier compared to directly attaching the panels to the exterior walls of a building, thereby reducing the time and labor required for installation and increasing the efficiency of the exterior panel installation work.

[0007] However, conventional exterior panels had a complex structure, which made manufacturing cumbersome and resulted in reduced productivity.

[0008] In addition, conventional exterior panels were typically joined to the frame using screw fastening, and since support was provided only by screw fastening, the exterior panels often deformed or separated from the frame as the screws loosened, especially when an earthquake or typhoon occurred, which caused the damage from the earthquake or typhoon to increase.

[0009] For the reasons mentioned above, attempts are being made in this field to develop architectural exterior panels that not only increase productivity by facilitating manufacturing but also ensure stable installation by enhancing seismic and wind pressure resistance through added load-bearing capacity; however, satisfactory results have not been achieved to date. Prior art literature

[0010] Republic of Korea Registered Patent Publication No. 10-2250859 The problem to be solved

[0011] The present invention is proposed to resolve the problems of the prior art as described above, and aims to provide an exterior building panel that not only increases productivity by facilitating manufacturing, but also ensures stable installation by improving seismic performance and wind pressure resistance through the addition of flow performance by a movable bracket and support force by a reinforcing member. means of solving the problem

[0012] To achieve the above objective, the present invention,

[0013] A metal exterior building panel with improved seismic performance, incorporating a movable bracket, is proposed, characterized by comprising: a body formed in the shape of a square plate, having a folded piece provided at each end of the width direction and the other end of the length direction; a plurality of fixed brackets disposed on the inner surface of each of the folded pieces of the body; a plurality of movable brackets fitted and coupled to each of the fixed brackets; a plurality of support brackets disposed facing each other with one of the folded pieces disposed at the width direction end and the other end of the body among the folded pieces; and a reinforcing member having a 'U'-shaped cross-section disposed between one of the support brackets and the other that face each other.

[0014] The above-mentioned bent piece includes: a first groove formed at multiple points between one end and the other end; and a pair of first through holes formed at the lower portion of each of the first grooves.

[0015] The first groove formed in one of the above-mentioned bent pieces is arranged offset from the first groove formed in the other bent piece located in the opposite direction.

[0016] Among the above-mentioned bent pieces, one and the other bent piece disposed at one end and the other end in the width direction of the body comprises: a second groove formed at at least one point between the one end and the other end; and a pair of second through holes formed at the lower part of the second groove.

[0017] The above fixing bracket comprises: a protruding piece connected between one end and the other end in the longitudinal direction, with the tip formed in an arc shape; and a pair of third through holes formed spaced apart below the protruding piece.

[0018] The above-described movable bracket comprises: a groove formed in an arc shape with a partially open inner surface, extending between one end and the other end in the longitudinal direction; a first insertion opening formed in the middle between one end and the other end of a surface extending to the outside of the bent piece; and openings formed on one side and the other side of the first insertion opening.

[0019] The groove portion of the above-mentioned movable bracket is formed such that its inner diameter is larger than the outer diameter of the tip of the protruding piece formed in the above-mentioned fixed bracket.

[0020] The support bracket comprises: a pair of through holes formed on one surface in contact with the inner surface of the bent piece; a first protruding piece extending into the body from the lower end of the one surface in contact with the inner surface of the bent piece; and a second protruding piece extending outward from the upper end of the one surface in contact with the inner surface of the bent piece.

[0021] The above reinforcing member includes a groove formed at each of one end and the other end in the longitudinal direction.

[0022] The groove portion of the above reinforcing member can be connected to the support bracket by welding.

[0023] The top of the above reinforcing member is located at the same height as the top of the above bent piece. Effects of the invention

[0024] A metal exterior building panel with improved seismic performance using a movable bracket according to the present invention includes a 'U'-shaped reinforcing member connected to one of the support brackets and the other, and extending between the lower end of one of the folded pieces positioned at one end of the body in the width direction and the lower end of the other. Since the twisting and bending of the body can be suppressed by the support provided by the reinforcing member, seismic performance and wind pressure resistance can be improved, thereby allowing the installation state to be maintained stably even in situations such as earthquakes or typhoons.

Specific details for implementing the invention

[0027] The present invention will be described in detail below with reference to the attached drawings.

[0029] As illustrated in FIGS. 1, 2 and 3, a metal exterior building panel (A) with improved seismic performance using a movable bracket according to the present invention comprises: a body (100); a fixed bracket (200); a movable bracket (300); a support bracket (400); and a reinforcing member (500).

[0030] The body (100) of the present invention is formed in the shape of a square plate, and a folded piece (110) is provided at each of one end and the other end in the width direction and length direction, respectively.

[0031] At this time, the bending piece (110) includes a first groove (111) formed at multiple points between one end and the other end; and a pair of first through holes (112) formed at the lower part of each of the first groove (111), thereby allowing a part of the movable bracket (300) to be caught in the first groove (111) and allowing a rivet (not shown in the drawing) to pass through the first through holes (112).

[0032] Here, the first groove (111) formed on one of the bending pieces (110) is positioned so as to be offset from the first groove (111) formed on the other bending piece (110) located in the opposite direction, so that when multiple bodies (100) are arranged in succession up and down or left and right, the movable bracket (300) coupled to the bending piece (110) provided at one end of the width direction and one end of the length direction of one body (100) and the movable bracket (300) coupled to the bending piece (110) provided at the other end of the width direction and the other end of the length direction of another body (100) are positioned so as to be offset from each other, that is, arranged in a zigzag shape.

[0033] And among the bending pieces (110), one and the other bending piece (110) disposed at one end and the other end in the width direction of the body (100) include a second groove (113) formed at least one point between the end and the other end; and a pair of second through holes (114) formed at the lower part of the second groove (113), so that the support bracket (400) can be mounted by the second groove (113) and the rivet can be penetrated by the second through holes (114).

[0034] The fixing bracket (200) of the present invention is provided in a plurality and is placed on the inner surface of each of the bent pieces (110) of the body (100).

[0035] At this time, the fixed bracket (200) includes a protruding piece (210) that is connected between one end and the other end in the longitudinal direction and has a leading edge formed in an arc shape; thereby, the groove of the movable bracket (300) described below is fitted and coupled to the leading edge of the protruding piece (210), so that the movable bracket (300) can slide in the fixed bracket (200).

[0036] And the fixing bracket (200) includes a pair of third through holes (220) formed at a distance from each other on the lower part of the protruding piece (210), so that the rivet can be penetrated by the third through holes (220).

[0037] The movable bracket (300) of the present invention is provided in a plurality of units and is rotatably coupled to each fixed bracket (200).

[0038] At this time, the movable bracket (300) includes a groove (310) formed in an arc shape with a partially open inner surface, which is connected between one end and the other end in the longitudinal direction; thereby, the tip of the protruding piece (210) of the fixed bracket (200) can be fitted and coupled by the groove (310).

[0039] Here, the inner diameter of the groove (310) is formed to be larger than the outer diameter of the tip of the protruding piece (210) provided in the fixed bracket (200), so that when the tip of the protruding piece (210) of the fixed bracket (200) is inserted into the groove (310) of the movable bracket (300), multi-directional movement of the movable bracket (300), such as left-right sliding as well as movement in the up-down and front-back directions, can be achieved.

[0040] And the movable bracket (300) includes a first insertion opening (320) formed in the middle between one end of a surface extending to the outside of the bent piece (110) and the other end, so that the fastening member can be penetrated by the first insertion opening (320).

[0041] At this time, the fastening member penetrating the first insertion hole (320) is a piece with a diameter of 4.8 to 6 mm having a hexagonal head, so the fastening force can be increased compared to a general fastening member with a diameter of 4 mm or less, and through the role of a fastening guide for the fastening member for vertical fastening, the vertical fastening strength of the metal exterior building panel (A) and frame (10) with improved seismic performance applied using the movable bracket according to the present invention can be increased.

[0042] And the movable bracket (300) includes an opening (330) formed on one side and the other side of the first insertion opening (320), so that when the fastening member is fastened, the connection between the opening (330) and the first insertion opening (320) is broken by an external impact, and as the opening (330) is opened, the left and right movement of the body (100) can be achieved.

[0043] The support bracket (400) of the present invention is provided in a plurality of portions and is positioned so as to face each other with one of the bending pieces (110) that is positioned at one end of the width direction of the body (100) and the other end.

[0044] At this time, the support bracket (400) includes a pair of through holes (410) formed on one side that contacts the inner surface of the bent piece (110), so that the rivet can be penetrated by the through holes (410).

[0045] Here, the unidirectional opening width of the through hole (410) is formed to be larger than the diameter of the rivet, so that when an impact is transmitted from the outside, the movement of the body (100) can be achieved, thereby providing a cushioning effect.

[0046] And the support bracket (400) further includes a first protruding piece (420) extending into the body (100) from the lower end of one surface in contact with the inner surface of the bending piece (110); and a second protruding piece (430) extending outward from the upper end of one surface in contact with the inner surface of the bending piece (110); so that unintended movement of the reinforcing member (500) can be suppressed as the first protruding piece (420) is inserted into the groove (510) of the reinforcing member (500) described below, and also unintended movement of the support bracket (400) in the body (100) can be suppressed as the second protruding piece (430) engages with the second groove (113) formed in the bending piece (110).

[0047] At this time, an insertion opening (440) is formed in the second protruding piece (430), so that the fastening member can be inserted through the insertion opening (440).

[0048] The reinforcing member (500) of the present invention has a 'U'-shaped cross-section and is positioned between one of the support brackets (400) facing each other and the other.

[0049] At this time, the reinforcing member (500) includes a groove (510) formed at each of one end and the other end in the longitudinal direction, so that a part of the support bracket (400), i.e., the first protruding piece (420), can be inserted through the groove (510).

[0050] Here, the reinforcing member (500) is connected to the support bracket (400) by welding, so that the connection between the reinforcing member (500) and the support bracket (400) can be maintained stably.

[0051] And the upper part of the reinforcing member (500) is positioned at the same height as the upper part of the bent piece (110), so that when the upper part of the bent piece (110) comes into contact with the frame (10), the upper part of the reinforcing member (500) can also come into contact with the frame (10).

[0053] The improvement in seismic performance and wind pressure resistance in a metal building exterior panel (A) with improved seismic performance by applying a movable bracket according to the present invention is described in detail as follows.

[0054] A metal exterior building panel (A) with improved seismic performance, to which a movable bracket according to the present invention is applied, is provided in multiple units as shown in FIG. 4 and is coupled to a frame (10) that is fixedly installed on the front of the exterior wall of a building.

[0055] At this time, one end in the longitudinal direction and the other end of the body (100) are fixed to one horizontal part (11) and the other horizontal part (11) below it that form the frame (10), and one end in the width direction and the other end of the body (100) are fixed to one vertical part (12) and the other vertical part (12) on one side thereof that form the frame (10).

[0056] Here, the fixation of the body (100) to the frame (10) can be achieved by fastening a fastening member.

[0057] That is, a bending piece (110) is provided at each end of the width direction and the other end of the body (100) in the length direction, and a fixing bracket (200) is disposed on each bending piece (110), and a movable bracket (300) is rotatably coupled to each fixing bracket (200). As a result, the body (100) can be fixed to the frame (10) by fastening the fastening member while the part of the movable bracket (300) exposed outside the bending piece (110) is in contact with the vertical part (12) and the horizontal part (11) of the frame (10).

[0058] Therefore, as the metal exterior building panel (A) with improved seismic performance, in which the movable bracket according to the present invention is applied to the entire frame (10), is fixed, the exterior appearance of the building can be made beautiful.

[0059] At this time, the movable bracket (300) includes a first insertion hole (320) formed in the middle between one end of a surface extending to the outside of the bending piece (110) and the other end, so that the body (100) can be fixed to the frame (10) as a fastening member penetrating the first insertion hole (320) is fastened to the frame (10).

[0060] And each of the bent portions (110) of the body (100) includes a first groove (111) formed at multiple points between one end and the other end, so that the mounting of the movable bracket (300) can be stably achieved by the catch formed by the first groove (111).

[0061] Each of the bending pieces (110) of the body (100) includes a pair of first through holes (112) formed at the lower part of each of the first grooves (111); and the fixing bracket (200) includes a pair of third through holes (220) formed at a distance from each other at the lower part of the protruding piece (210), so that the fixing bracket (200) can be stably connected to the bending piece (110) by riveting when the center of the first through hole (112) and the center of the third through hole (220) coincide.

[0062] However, if the fastening force of the fastening member is insufficient, the fixation of the body (100) to the frame (10) may become unstable, and thus the fixation of the body (100) may be released by vibration or wind, especially in situations such as earthquakes or typhoons.

[0063] However, the fastening member penetrating the first insertion hole (320) of the movable bracket (300) of the present invention is a piece with a diameter of 4.8 to 6 mm having a hexagonal head, so that the fastening force can be increased compared to a general fastening member with a diameter of 4 mm or less, and thus the fixed state of the body (100) can be stably maintained.

[0064] In addition, the movable bracket (300) of the present invention includes an opening (330) formed on one side and the other side of the first insertion opening (320). Therefore, when a fastening member is fastened to the first insertion opening (320), the connection portion between the opening (330) and the first insertion opening (320) is broken by an external impact, and the opening (330) is opened. As the body (100) moves left and right through the opening (330) with the broken connection portion, the shock applied from the outside can be mitigated, and the fixed state of the body (100) can be stably maintained.

[0065] Meanwhile, the metal exterior building panel (A) with improved seismic performance, to which the movable bracket according to the present invention is applied, can further enhance seismic performance.

[0066] That is, the movable bracket (300) coupled to the fixed bracket (200) is fitted into the fixed bracket (200). When an external impact is applied while the body (100) is coupled to the frame (10) placed on the outer wall of the building, the movable bracket (300) slides on the fixed bracket (200), thereby mitigating the external impact and further enhancing seismic performance.

[0067] At this time, the fixed bracket (200) includes a protruding piece (210) that is connected between one end and the other end in the longitudinal direction as shown in FIG. 6 and has a tip formed in an arc shape, and the movable bracket (300) includes a groove (310) that is connected between one end and the other end in the longitudinal direction as shown in FIG. 7 and has an inner surface formed in an arc shape, so that the tip of the protruding piece (210) of the fixed bracket (200) is inserted into the groove (310) of the movable bracket (300), thereby allowing the movable bracket (300) to be fitted into the fixed bracket (200).

[0068] Here, the inner diameter of the groove (310) provided in the movable bracket (300) is formed to be larger than the outer diameter of the tip of the protruding piece (210) provided in the fixed bracket (200). Due to the difference between the inner diameter of the groove (310) of the movable bracket (300) and the outer diameter of the tip of the protruding piece (210) of the fixed bracket (200), the tip of the protruding piece (210) of the fixed bracket (200) is inserted into the groove (310) of the movable bracket (300). As shown in FIG. 10, sliding of the movable bracket (300) can be performed within the range of the first groove (111). Furthermore, as shown in FIG. 11, multi-directional movement, such as movement in the up-down and forward-backward directions, can be performed. This allows for the mitigation of impacts applied from the outside, thereby further enhancing seismic performance.

[0069] In addition, the metal exterior building panel (A) with improved seismic performance, to which the movable bracket according to the present invention is applied, can suppress twisting and bending of the body (100) in the installed state.

[0070] That is, the present invention includes a 'U'-shaped reinforcing member (500) positioned between one of the mutually facing support brackets (400) and the other. Since the body (100) is supported by the reinforcing member (500), the twisting and bending of the body (100) can be suppressed, thereby improving seismic performance and wind pressure resistance, so that the fixed state of the body (100) can be maintained more stably, especially in situations such as earthquakes or typhoons.

[0071] At this time, among the bending pieces (110), one and the other bending piece (110) positioned at one end and the other end in the width direction of the body (100) include a second groove (113) formed at least one point between the end and the other end, and the support bracket (400) further includes a second protruding piece (430) extending outward from the upper end of one surface that contacts the inner surface of the bending piece (110) to the outside of the body (100); and as the second protruding piece (430) of the support bracket (400) engages with the second groove (113), the left and right movement of the support bracket (400) in the body (100) can be suppressed, so that the support bracket (400) can be stably mounted on the body (100).

[0072] Here, since an insertion hole (440) is formed in the second protruding piece (430) of the support bracket (400), the support bracket (400) can be fixed to the frame (10) as a fastening member inserted into the insertion hole (440) is fastened to the frame (10).

[0073] And among the bending pieces (110), one and the other bending piece (110) positioned at one end and the other end in the width direction of the body (100) include a pair of second through holes (114) formed at the lower part of the second groove (113), and the support bracket (400) includes a pair of through holes (410) formed on one surface that contacts the inner surface of the bending piece (110), so that the support bracket (400) can be stably connected to the bending piece (110) as riveting is performed with the center of the second through hole (114) and the center of the through hole (410) coinciding.

[0074] And the reinforcing member (500) includes a groove (510) formed at each of the longitudinal ends and the other end as shown in FIG. 9, and the support bracket (400) further includes a first protruding piece (420) extending into the body (100) from the bottom of one side in contact with the inner surface as shown in FIG. 8, so that as the first protruding piece (420) of the support bracket (400) is inserted into the groove (510), the left and right movement of the reinforcing member (500) can be suppressed, and thus the support of the body (100) by the reinforcing member (500) can be made more stably.

[0075] Here, since the reinforcing member (500) and the support bracket (400) are partially welded, the connection between the reinforcing member (500) and the support bracket (400) can be maintained stably.

[0076] In addition, the metal exterior building panel (A) with improved seismic performance, to which the movable bracket according to the present invention is applied, can facilitate finishing between one of the bodies (100) and another adjacent body (100) while the body (100) is fixed to the frame (10).

[0077] That is, in the present invention, the first groove (111) formed on one of the bending pieces (110) is arranged so as to be offset from the first groove (111) formed on the other bending piece (110) located in the opposite direction. As shown in FIG. 5, when the body (100) is arranged consecutively in the vertical or horizontal direction, the movable bracket (300) coupled to the bending piece (110) provided at one end of the width direction and one end of the length direction of one body (100) and the movable bracket (300) coupled to the bending piece (110) provided at the other end of the width direction and the other end of the length direction of another body (100) are offset from each other so that overlapping is prevented. Therefore, the gap between one of the bodies (100) fixed to the frame (10) and the other body (100) adjacent thereto can be reduced, and silicone, etc. can be filled between one of the bodies (100) and the other body (100) adjacent thereto. The finishing work can be easily carried out.

[0079] The present invention, as described above, is not limited to the embodiments described above and may be modified within the scope that does not deviate from the essence of the invention claimed in the claims, and such modifications fall within the scope of protection of the present invention as defined by the claims below.
