Ceiling panel fixing structure for optimizing ceiling thickness {Ceiling panel fixing structure}

The present invention relates to a ceiling panel fixing structure for optimizing the ceiling thickness, which secures a ceiling height by minimizing the thickness of the ceiling panel fixing structure while securing sufficient space for equipment piping by connecting first and second embars spaced vertically apart with hangers, and wherein the anchor bolts that connect the upper surface of the first embar to the upper slab do not interfere with equipment piping.

Recently, as the generation-to-generation conflict due to noise between floors has become a serious social problem, various methods are being attempted to reduce noise between floors. Accordingly, the thickness of the floor slab structure can be increased, but in this case, the floor height increases by the increased thickness of the slab structure to secure the ceiling height, so the amount of frame material increases. In addition, since the height of the entire building also increases as the height of each floor increases, the number of floors inevitably decreases, which is economically disadvantageous.

Meanwhile, in apartment complexes, ceiling panels are installed under the upper slab to prevent electrical wiring and equipment pipes from being exposed to the outside and to improve the appearance.

The conventional general ceiling panel fixing structure installs a fixing bolt on the lower surface of the upper slab, fixes the upper end of a sawtooth bracket (or bracket bolt) to the fixing bolt, and suspends and fixes a carrier channel on the lower end of the bracket bracket. Then, an embar is combined on the lower portion of the carrier channel in a direction perpendicular to the carrier channel, and multiple rows of carrier channels and embars are arranged in a grid shape, and the ceiling panel is fixedly installed on the lower surface of the embar (Patent Registration No. 10-1943018).

Typically, an apartment-type ceiling system requires a space of approximately 170 mm in height, including a 130 mm space for the piping underneath the upper slab and a 40 mm thickness for the carrier channel, embar, and ceiling panel.

Therefore, if the thickness of the ceiling panel fixing structure is reduced, the required ceiling height can be secured without increasing the floor height even if the thickness of the floor slab is increased.

In the conventional ceiling panel fixing structure, a sawtooth bracket is attached to the upper part of the carrier channel, and an embar is attached to the lower part at a position spaced from the sawtooth bracket, so that a load is applied to the carrier channel. At this time, if the thickness of the carrier channel is reduced in order to reduce the thickness of the ceiling panel fixing structure, the bending rigidity of the carrier channel is reduced, so the interval between the sawtooth brackets, which serve as supports, must be reduced. However, if the installation locations of the sawtooth brackets increase, there is a problem that the workability is reduced because they interfere with each other when laying equipment piping.

In order to solve the above problems, the present invention provides a ceiling panel fixing structure for optimizing the ceiling thickness by minimizing the thickness of the ceiling panel fixing structure while sufficiently securing equipment piping space on the upper part of the ceiling panel, thereby sufficiently securing the ceiling height.

According to a preferred embodiment, the present invention comprises: a plurality of rows of first embars, each of which has an opening formed longitudinally at a lower portion, and on both sides of the opening, catches are formed by bending inward, and each of which has an upper surface fixedly installed so as to be in close contact with a lower surface of an upper slab; a plurality of rows of second embars, each of which has an opening formed longitudinally at an upper portion, and catches are formed by bending inward on both sides of the opening, and each of which is arranged at a lower portion of the first embar so as to be spaced apart from the first embar in a direction perpendicular to the first embar; And the upper and lower ends are respectively inserted into the openings of the first embar and the second embar and are joined to the engaging portions, and engaging grooves into which the engaging portions of the first embar are inserted and engaged are formed on both sides thereof, so that the upper head is inserted into the opening of the first embar and is joined to the engaging portions, the lower head is inserted into the opening of the second embar and is joined to the engaging portions by forming engaging grooves into which the engaging portions of the second embar are inserted and engaged on both sides thereof, and the connecting bar is formed so as to connect the upper head and the lower head by screw-connecting at least one of the upper head and the lower head so that the distance between the upper head and the lower head can be adjusted, the ceiling panel fixing structure for optimizing the ceiling thickness is provided, characterized in that the lower head is formed in a hemispherical shape whose width becomes narrower toward the bottom, and the engaging groove is continuously formed along the outer circumference of the lower head.

According to the present invention, a first embar and a second embar, each having an opening on the lower surface and the upper surface thereof, are arranged vertically apart and connected by a hanger, and a ceiling panel fixing structure is provided in which anchor bolts connecting the upper surface of the first embar to the upper slab do not interfere with equipment piping, so that the installation location of the anchor bolts can be freely set and sufficient equipment piping space can be secured on the upper surface of the ceiling panel.

In addition, since the upper and lower ends of the hanger are inserted into the openings of the first and second embars respectively and are caught on the hooks, the hanger can be freely installed at any location along the first embar, making construction convenient.

In addition, the carrier channel of the conventional ceiling panel fixing structure can be omitted, and since there is no cross-sectional loss of the first embar, the thickness of the first embar can be minimized, so the thickness of the ceiling panel fixing structure can be minimized. Accordingly, even if the floor slab thickness is increased to reduce interfloor noise, the required ceiling height can be secured without increasing the floor height.

Hereinafter, the present invention will be described in detail with reference to the attached drawings and preferred embodiments.

As illustrated in FIGS. 1 to 4, the ceiling panel fixing structure for optimizing the ceiling thickness of the present invention comprises: a plurality of rows of first EMs (3), each of which has an opening (30) formed longitudinally at the bottom, and hooks (31) formed by bending inward on both sides of the opening (30), and fixedly installed so that the upper surface is in close contact with the lower surface of the upper slab (1); a plurality of rows of second EMs (4), each of which has an opening (40) formed longitudinally at the top, and hooks (41) formed by bending inward on both sides of the opening (40), and arranged so as to be spaced apart from the first EMs (3) in a direction perpendicular to the first EMs (3) at the lower portion of the first EMs (3); and a plurality of hangers (5), each of which has an upper end and a lower end inserted into the openings (30, 40) of the first EMs (3) and the second EMs (4), and is coupled to the hooks (31, 41). It is characterized by being composed of:

The present invention provides a ceiling panel fixing structure for optimizing the ceiling thickness by minimizing the thickness of the ceiling panel fixing structure while securing sufficient equipment piping space on the upper part of the ceiling panel (2) to sufficiently secure the ceiling height.

The ceiling panel fixing structure of the present invention is composed of a plurality of rows of first embars (3) and second embars (4) and a hanger (5) connecting the first and second embars (3, 4), and, unlike the existing ceiling panel fixing structure, the carrier channel is omitted.

The first embar (3) above is opened at the bottom to form an opening (30) extending in the longitudinal direction of the first embar (3).

At the lower end of the first embar (3), a catch (31) is formed by folding inward on both sides of the opening (30). The catch (31) can be formed by folding the inner side of the lower end of the first embar (3) into an L-shape.

The upper surface of the above first embar (3) is in close contact with the lower surface of the upper slab (1).

The upper surface of the first embar (3) can be fixed to the upper slab (1) with an anchor bolt (6) so that the anchor bolt (6) acts as a support of the first embar (3).

The above first embars (3) are installed in parallel so as to be spaced apart from each other.

Since the above anchor bolt (6) does not interfere with the installation of the equipment piping, the installation location can be freely set. Accordingly, the thickness of the first embar (3) can be minimized.

The above second embar (4) has an opening (40) formed longitudinally at the top, and a catch (41) is formed by bending inward on both sides of the opening (40).

The above second embar (4) can be formed with the same cross-section as the above first embar (3).

The above second embar (4) can be arranged symmetrically vertically with the first embar (3), and an opening (40) and a catch (41) are formed at the top.

The above second embars (4) are installed in parallel so as to be spaced apart from each other in multiple pieces. The above second embars (4) are arranged in a direction perpendicular to the first embars (3) to form a grid shape on a plane together with the first embars (3).

A ceiling panel (2) is attached to the lower part of the second embar (4).

The above first embar (3) and second embar (4) can be arranged so as to be spaced apart vertically by the equipment piping space.

The above hanger (5) interconnects the first embar (3) and the second embar (4) which are spaced vertically apart.

The upper part of the above hanger (5) is inserted into the opening (30) provided at the lower part of the first embar (3) and is connected to be caught on the hook (31).

The lower end of the above hanger (5) is inserted into the opening (40) provided in the upper part of the second embar (4) and is connected to be caught on the hook (41).

The conventional ceiling panel fixing structure required the continuous formation of long holes on the upper part of the carrier channel in order to connect the sawtooth bracket to the carrier channel. Accordingly, the flexural rigidity inevitably decreased due to the loss of cross-sectional area of the carrier channel.

In contrast, the present invention allows the hanger (5) to be freely installed at any location by sliding along the first embar (3) since the hanger (5) is inserted and hung in the opening (30) provided at the bottom of the first embar (3). In addition, since there is no need to form a separate hole in the first embar (3), there is no cross-sectional loss, and thus the thickness of the first embar (3) can be minimized.

As shown in Fig. 3, the hanger (5) may be composed of an upper head (51) that is inserted into the opening (30) of the first embar (3) and coupled to a hook (31), a lower head (52) that is inserted into the opening (40) of the second embar (4) and coupled to a hook (41), and a connecting bar (53) that connects the upper head (51) and the lower head (52).

In order to connect the above hanger (5) to the first embar (3) and the second embar (4), the hanger (5) may be composed of an upper head (51), a lower head (52), and a connecting bar (53) connecting the upper and lower heads (51, 52).

Since the first embar (3) and the second embar (4) to which the upper and lower ends of the above hanger (5) are respectively connected can be formed with the same shape, the upper head (51) and the lower head (52) can also be formed with the same shape.

The width of the upper head (51) and lower head (52) can be formed wider than the width of the opening (30, 40) so that they can be caught on the catches (31, 41) on both sides.

As shown in FIG. 2 and FIG. 4, the upper head (51) can be simply placed on the upper part of the catch (31) of the first embar (3).

And the lower head (52) can support the lower part of the catch (41) of the second embar (4).

The above connecting bar (53) can be configured to be screw-connected to at least one of the upper head (51) and the lower head (52) so as to adjust the distance between the upper head (51) and the lower head (52).

The height of the ceiling space may vary depending on the utility piping embedded within the ceiling system.

In this case, the upper head (51) and/or the lower head (52) are screw-connected to the connecting bar (53) so that a single standard product can be used without replacing the hanger (5), and the distance between the upper and lower heads (51, 52) can be adjusted by rotating the upper and lower heads (51, 52) or the connecting bar (53).

Fig. 5 is a perspective view illustrating another embodiment of a hanger, and Figs. 6 to 8 are perspective views illustrating a joining process of the hanger illustrated in Fig. 5.

As shown in Fig. 5, the upper head (51) and the lower head (52) can have engaging grooves (511, 521) formed on both sides into which the engaging parts (31, 41) are inserted and engaged.

As shown in Figures 3 and 4, if the hanger (5) is simply hung and installed, it is maintained in place by the weight of the ceiling panel (2), so it may fall off due to external force and is vulnerable to vibration.

Accordingly, a hook groove (511, 521) can be formed on each side of the upper head (51) and lower head (52) of the hanger (5).

Accordingly, the catch (31) of the first embar (3) can be inserted into the catch groove (511) of the upper head (51) to firmly secure the upper head (51) to the catch (31) of the first embar (3).

And the catch (41) of the second embar (4) can be inserted into the catch groove (521) of the lower head (52) to firmly fix the catch (41) of the lower head (52) and the second embar (4).

The upper head (51) and lower head (52) above can be formed of synthetic resin, metal, etc.

In particular, if the upper head (51) and lower head (52) are made of earthquake-resistant rubber, which is a hard elastic material, the load of the ceiling panel (2) can be stably supported while absorbing vibrations. Accordingly, the joint damage can be prevented, ensuring stability when an earthquake occurs.

The joining process of the hanger (5) is explained as follows with reference to FIGS. 6 to 8.

The upper head (51) and lower head (52) can be formed as a rectangular shape with one side longer than the other on a plane. Then, the long side direction of the upper head (51) and lower head (52) is made the same as the length direction of the opening (30, 40) so that they pass through the opening (30, 40) between the catches (31, 41) (Fig. 6, Fig. 7)

Figures 6 and 7 illustrate the step of inserting the upper head (51) into the opening (30) of the first embar (3) and the inserted state, respectively.

When the engaging grooves (511, 521) of the upper and lower heads (51, 52) are positioned at the height of the engaging parts (31, 41) of the first and second embars (3, 4), the hanger (5) is rotated 90° to insert the engaging parts (31, 41) into the engaging grooves (511, 521) and fasten them (Fig. 8).

As shown in Figure 5, the lower head (52) may be formed to have a width that becomes narrower as it goes toward the outer end.

The ceiling panel fixing structure of the present invention can be constructed in the following order: first attaching the first embar (3) to the lower surface of the upper slab (1), then attaching the hanger (5) to the first embar (3), and then installing the second embar (4) at the bottom of the hanger (5).

At this time, when the above hanger (5) is connected to the first embar (3), the second embar (4) is not installed at the bottom of the hanger (5). Accordingly, the upper head (51) of the hanger (5) is aligned in the longitudinal direction of the opening (30) and inserted into the opening (30), and then the hanger (5) can be rotated 90°.

However, when the second embar (4) is combined, the upper part of the hanger (5) is already combined with the first embar (3) above, making it difficult to rotate the hanger (5).

Accordingly, the width of the outer end of the lower head (52), i.e., the lower end, can be formed to become narrower so that the lower head (52) of the hanger (5) can be pressed into the second embar (4) and fitted.

At this time, since the engaging portion (41) of the second emba (4) must be inserted into the engaging groove (521) of the lower head (52) and be hooked up and down, it is preferable to form the lower portion of the engaging groove (521) to be tapered so that it becomes narrower toward the bottom to enable stable support. In addition, it is preferable to form the tapered portion to be curved outward so that it can easily enter the opening (40) of the second emba (4) while maintaining an appropriate thickness to stably support the engaging portion (41).

The above second embar (4) can be formed by bending a metal plate. Accordingly, it has its own elasticity, so when the lower head (52) enters the opening (40), the engaging portions (41) on both sides are temporarily spread along the outer surface of the lower head (52) and then elastically restored at the position of the engaging groove (521), so that the engaging portions (41) can be inserted into the engaging groove (521).

Meanwhile, in order to allow the lower head (52) to enter the opening (40) more easily, an arch-shaped recessed portion (522) may be formed at the lower end of the lower head (52). By inducing elastic deformation of the lower head (52) by the recessed portion (522), the lower head (52) can easily enter the opening (40).

The upper head (51) above can also form a recessed portion (512) in the upper portion in the same shape as the lower head (52). In this case, the upper head (51) can be fitted into the opening (30) of the first amber (3) by applying pressure.

The upper head (51) or lower head (52) may be formed into a rectangular shape on a flat surface and rotated 90° to be connected to the first and second embars (3, 4), respectively, or may be formed with a width that becomes narrower toward the outer end and may be selectively used to fit into the openings (30, 40) of the first and second embars (3, 4) by applying pressure.

FIG. 9 is a perspective view showing a hanger equipped with a hemispherical lower head, FIG. 10 is a perspective view showing a hanger equipped with hemispherical upper and lower heads, and FIG. 11 is a cross-sectional perspective view showing the upper head or the lower head.

As shown in FIGS. 9 to 11, the lower head (52) is formed in a hemispherical shape, and the engaging groove (521) can be formed continuously along the outer circumference of the lower head (52).

Since the above second embar (4) is formed in a direction orthogonal to the first embar (3), the upper head (51) and the lower head (52) must also be provided in a direction orthogonal to each other.

However, when the above connecting bar (53) is screw-connected to the upper head (51) and the lower head (52), it is not easy to maintain the upper head (51) and the lower head (52) at an exact right angle. Accordingly, when the upper head (51) or the lower head (52) is connected to the first embar (3) or the second embar (4) at an angle, the engaging portions (31, 41) of the first and second embars (3, 4) may come off from the engaging grooves (511, 521) of the upper and lower heads (51, 52).

Accordingly, the lower head (52) can be formed into a circular shape on a plane so that the lower head (52) can be fastened in any direction.

At this time, in order to facilitate entry into the opening (40) formed in the upper portion of the second emba (4), the lower head (52) may be formed in a hemispherical shape with the width becoming narrower as it goes downward.

The upper head (51) above can also be formed in a hemispherical shape, similar to the lower head (52) (Fig. 10). In some cases, the upper head (51) can be formed in a rectangular shape and the lower head (52) can be formed in a hemispherical shape (Fig. 9).

Even when the lower head (52) is formed in a hemispherical shape, a recessed portion (522) can be formed at the outer end to enable elastic deformation of the lower head (52) (Fig. 11). Similarly, in the case of the hemispherical upper head (51), a recessed portion (512) can be formed at the outer end.
