[0022] Referring to the drawings above, a seismic ceiling panel fixing device (10) according to one embodiment of the present invention comprises: a carrying channel (100) that is coupled to a hanger bolt (not shown) installed on a ceiling slab; a clip bar (200) that is coupled to the carrying channel (100) at a certain distance and is arranged perpendicularly to the carrying channel (100) on the bottom surface of the carrying channel (100), and is composed of a locking wing portion (210) that is double-layered at both upper ends and inclined downward, a resilient portion (220) that narrows toward the center and forms an inverted triangle on both sides of the lower surface, and a ceiling panel insertion portion (230) into which a protrusion of the ceiling panel can be inserted at the center of the lower portion; and a wire clip (300) for coupling the carrying channel (100) and the clip bar (200).

[0023] Additionally, the carrying channel (100) includes a vertically erected standing plate (110), a first extension plate (120) that is bent integrally at one end of the standing plate (110) and placed on the upper side of the clip bar, and a second extension plate (130) that is bent integrally at the other end of the standing plate (110) and extends parallel to the first extension plate (120).

[0024] In addition, the first extension plate (120) has a first folding plate (120t) that folds inward, so that the structural rigidity is increased with double thickness, and the second extension plate (130) has a second folding plate (130t) that folds inward, so that the structural rigidity is increased with double thickness, making it strong against earthquakes and wind pressure.

[0025] Additionally, the wire clip (300) comprises a contact portion (310) surrounding the upper surface of the carrying channel (100), a tension portion (320) extending downwardly at both ends of the contact portion (310), and a locking portion (330) bent at the end of each tension portion (320) and hooked to the lower side of each locking wing portion (210), wherein a slit (221) is formed at regular intervals along the longitudinal direction on the side of the elastic portion (220).

[0026] Additionally, the end of the above-mentioned catch portion (330) is bent again along the longitudinal direction of the above-mentioned slit (221) to form an anti-detachment portion (340) that can be inserted into the above-mentioned slit (221) and caught, and an elastic coil portion (360) that is wound in a coil shape at least once is formed in one of the above-mentioned tension portions (320).

[0027] Additionally, the wire clip (300) comprises a contact portion (310) surrounding the upper surface of the carrying channel (100), a tension portion (320) extending downwardly at both ends of the contact portion (310), and a locking portion (330) bent at the end of each tension portion (320) and hooked to the lower side of each locking wing portion (210), wherein a slit (221) is formed at regular intervals along the longitudinal direction on the side of the elastic portion (220).

[0028] Additionally, the end of the above-mentioned catch portion (330) is bent downward to form a bent portion (350) that extends to the slit (221), and the end of the bent portion (350) is bent upward again to form an anti-detachment portion (340) that is inserted into the slit (221).

[0029] Additionally, the wire clip (300) may further include an elastic coil portion (360) wound in a coil shape at least once on the tension portion (320).

[0031] Then, the configuration and use of the seismic ceiling panel fixing device (10) according to the embodiments of the present invention will be specifically described as follows.

[0032] The seismic ceiling panel fixing device (10) proposed by the present invention is a fixing device coupled to a hanger bolt (not shown) installed on a ceiling slab, and, as shown in FIG. 2, etc., mainly includes a carrying channel (100), a clip bar (200), and a wire clip (300), etc.

[0034] Here, the carrying channel (100) is a construction component that is connected to a hanger bolt (not shown) installed on the ceiling slab of a building, and is widely used to connect a clip bar for fastening a ceiling panel to the lower part or to fix various pipes or cable trays to the upper part.

[0035] In addition, the carrying channel (100) forms a 'U'-shaped or "C"-shaped channel as shown in the cross-section, which can solve the problem of the ceiling finishing material being exposed to the risk of tearing during seismic or wind pressure tests due to the weak strength of the conventional carrying channel.

[0036] That is, since the carrying channel (100) is mounted in a high place such as a ceiling slab of a building, it must be strongly suspended from the ceiling with minimal weight to avoid the risk of falling.

[0037] However, conventional carrying channels use lightweight aluminum material and have a thickness of 0.7t (mm), but there is a risk that the ceiling finishing material will fall off as the carrying channel tears during seismic or wind pressure tests.

[0038] To solve these problems, the carrying channel (100) uses a galvanized steel plate which is stronger than aluminum, and applies a thickness of 0.5t (mm) which is thinner than aluminum, so that it is lightweight and has excellent rigidity, and can be folded once more to achieve the effect of 1.0t (mm), and can prevent tearing or damage during seismic and wind pressure tests.

[0039] Accordingly, the carrying channel (100) proposed by the present invention includes, as illustrated in FIG. 3 and the like, a vertically erected plate (110), a first extension plate (120) that is bent integrally at one end of the vertical plate (110) and placed on the upper side of the clip bar, and a second extension plate (130) that is bent integrally at the other end of the vertical plate (110) and extends parallel to the first extension plate (120).

[0040] In particular, the first extension plate (120) has a double thickness and a first folding plate (120t) that folds inward, which increases structural rigidity and strongly resists vibration and wind pressure, and can contribute greatly to preventing ceiling finishing materials from falling.

[0041] In addition, the second extension plate (130) has a second folding plate (130t) that folds inward with double thickness and interacts with the first extension plate (120) to increase structural rigidity, thereby strongly resisting vibration and wind pressure, and can contribute greatly to preventing ceiling finishing materials from falling.

[0043] The clip bar (200) is fixed at a right angle to the bottom surface of the carrying channel (100) using a wire clip (300), as shown in FIG. 4, etc.

[0044] Specifically, the clip bar (200) has the same shape and form that are repeated continuously back and forth, and can be used as is or cut to the required length and manufactured by press forming, and the upper ends are double-layered and inclined downward to form a catch wing portion (210) on which a wire clip (300) can be caught, and on both sides of the lower surface, a resilient portion (220) is formed that is inclined to narrow towards the center and forms an approximately inverted triangle shape, a ceiling panel insertion portion (230) formed in a hemispherical shape in the center of the lower part is formed, and a guide portion (240) that is spread outward at the lower end so that the edge of the ceiling panel (10) can be guided is formed.

[0045] Additionally, a pressure surface may be further formed between the ceiling panel insertion part (230) and the guide part (240) so that the edge of the ceiling panel (10) can be closely attached.

[0046] Additionally, when installing the ceiling panel (10), the elastic part (220) can be in close contact with the lower surface by the force of the ceiling panel (10) pressing upward, and the pressure surface is easily relaxed by the close elastic part (220) so that the ceiling panel (10) is easily inserted into the ceiling panel insertion part (230). After the ceiling panel (10) is inserted, the elastic part (220) is restored to have elasticity by separating from the lower surface due to the load of the ceiling panel (10), and the pressure surface is strongly in close contact with the edge of the ceiling panel (10) so that the ceiling panel (10) is firmly fixed and installed without detaching from the clip bar (200).

[0047] Additionally, the ceiling panel insertion part (230) has through holes (231) formed at regular intervals so that the insertion projection (11) of the ceiling panel (10) is inserted and does not move back and forth.

[0048] In particular, a plurality of slits (221) are formed at regular intervals on the side of the elastic portion (220) of the clip bar (200).

[0049] That is, the slit (221) is perforated by punching and may have a horizontally elongated shape and is arranged along the longitudinal direction of the clip bar (200).

[0050] In addition, the vertical width of the slit (221) must be larger than the outer diameter of the wire clip (300) so that the anti-detachment part (340) of the wire clip (300) can be easily inserted into the slit (221), and the horizontal length of the slit (221) must be longer than the length of the anti-detachment part (340).

[0052] As illustrated in FIG. 7, the wire clip (300) is formed by bending or folding a wire into a roughly trapezoidal shape, and is configured to connect the clip bar (200) to the carrying channel (100) by having one end hooked onto one side of the clip bar (200) and passing over the upper part of the carrying channel (100) and hooked onto the other side of the clip bar (200). It may be composed of a contact part (310), a tension part (320), a hooking part (330), and an anti-detachment part (340).

[0053] At this time, the contact portion (310) is a part that surrounds and contacts the upper surface of the carrying channel (100), and the length of the contact portion (310) can be formed to be approximately equal to or longer than the width of the carrying channel (100).

[0054] Meanwhile, since the wire clip (300) is connected at an angle rather than at a right angle to the carrying channel (100), it is advantageous for the length of the contact portion (310) to be longer than the width of the upper surface of the carrying channel (100).

[0055] In addition, the tension portion (320) extending from both ends of the contact portion (310) is formed to slope downward toward the lower side.

[0056] The tension portion (320) is formed from the upper surface of the carrying channel (100) to the locking wing portion (210) of the clip bar (200) and actually supports the connection between the carrying channel (100) and the clip bar (200). That is, tension force is applied to the tension portion (320) to strongly tighten the carrying channel (100) and the clip bar (200). In addition, the end of each tension portion (320) is bent inward to form a locking portion (330).

[0057] The catch portion (330) is bent approximately 90˚ with the tension portion (320) and is caught on the lower side of each catch wing portion (210). In the present invention, the end of the catch portion (330) can be bent again to form a detachment prevention portion (340).

[0058] The anti-detachment part (340) can form an angle greater than approximately 90° with the catch part (330), but can be limited to a range of 90° to 120°. This is because it is optimal for the anti-detachment part (340) to be fixed in the longitudinal direction of the slit (221), that is, in the longitudinal direction of the elastic part (220), while inserted into the slit (221). Additionally, the anti-detachment part (340) must maintain a caught state so as not to detach after being inserted through the slit (221).

[0059] In addition, the length of the anti-detachment part (340) must be smaller than the length of the slit (221).

[0060] Accordingly, when the wire clip (300) is joined, the anti-detachment part (340) can be easily inserted into the slit (221), and conversely, when disassembling, the anti-detachment part (340) can be easily withdrawn from the slit (221).

[0062] In the present invention, a coil-shaped elastic coil part (360) may be further formed in any one of the tension parts (320), as shown in FIGS. 4 to 7, etc.

[0063] The elastic coil portion (360) can be formed by winding the wire one or more times in a circular manner, and can have a shape similar to a coil spring and function to absorb some of the impact when subjected to external impact.

[0064] Generally, when an impact is applied to the ceiling panel (10) while the ceiling panel (10) is fixedly fitted to the clip bar (200), the impact is transmitted to the clip bar (200).

[0065] In the past, there was a problem where the wire clip (300) detached from the clip bar (200) due to impact, causing the clip bar (200) to be separated from the carrying channel (100). However, in the present invention, the elastic coil part (360) absorbs a significant portion of this impact, thereby resolving the problem of the wire clip (300) detaching.

[0066] In addition, since an elastic coil part (360) is formed, there is also an advantage that the worker can easily open or close the wire clip (300) when attaching it.

[0067] In addition, it is more advantageous for the elastic coil portion (360) to be formed on only one of the tension portions (320) rather than on both of them.

[0068] This is because, during construction, the worker carries around many of the wire clips (300), and there is a problem with the wire clips (300) getting tangled together, so it may be cumbersome to separate them one by one. The problem of tangling may be exacerbated by the formation of the elastic coil section (360), and if the elastic coil section (360) is formed on both sides of the tension section (320), the work time may be delayed.

[0070] Another embodiment of the present invention, a wire clip (300), may include a contact portion (310), a tension portion (320), a catch portion (330), an anti-detachment portion (340), and a bending portion (350), as shown in FIGS. 8 to 10. Meanwhile, the contact portion (310) and the tension portion (320) are identical to those described above, so a description is omitted.

[0071] Here, the catch portion (330) is bent inward at the end of each tension portion (320) and caught on the lower side of the catch wing portion (210).

[0072] At this time, the catch portion (330) is bent at an acute angle smaller than approximately 90˚ with respect to the tension portion (320) and is caught on the lower side of each catch wing portion (210). As described above, since the catch wing portion (210) is formed with a slight downward slope, the catch portion (330) forms an acute angle with respect to the tension portion (320), thereby allowing it to be brought close to and in close contact with the lower surface of the catch wing portion (210).

[0073] In addition, a bent portion (350) is formed by bending downward from the end of the catch portion (330).

[0074] In particular, the bend portion (350) extends to the slit (221), and the slope of the bend portion (350) is formed to be the same or similar to the slope of the elastic portion (220), so that the bend portion (350) is formed to be close to the surface of the elastic portion (220).

[0075] This is to improve fastening by ensuring that the wire clip (300) is in close contact with the locking wing portion (210) and the elastic portion (220).

[0076] Additionally, the end of the bent portion (350) is bent upward again to form an anti-detachment portion (340). Accordingly, as shown in FIG. 10, the tension portion (320), the catch portion (330), the anti-detachment portion (340), and the bent portion (350) are bent into a shape approximately like 'W'.

[0077] At this time, the anti-detachment part (340) is inserted into the slit (221) and its end comes into almost contact with the lower surface of the catch wing part (210). Therefore, the end of the anti-detachment part (340) catches on the upper end of the slit (221), so that detachment can be prevented.

[0079] Although representative embodiments of the present invention have been described above with reference to the drawings, those skilled in the art will be able to make various applications and modifications within the scope of the present invention based on the above. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined by the claims set forth below as well as equivalents thereof.
