Description

Fixed bracket of seismic reinforcement type ceiling finishing system {Seismic reinforcement type ceiling finishing apparatus}

The present invention relates to an earthquake-resistant reinforcement type ceiling finishing system, and more particularly, to an earthquake-resistant reinforcement type ceiling finishing system with improved seismic resistance, durability, impact resistance and sound absorption, which is easy to install and construct.

In general, the indoor ceiling of buildings such as apartments, buildings, and general houses is covered with electrical wiring or various pipes so that they are not exposed to the outside, and finishing construction is performed to make the exterior beautiful.

Conventional indoor ceiling finishing construction is generally performed by installing a separate ceiling finishing device on the slab bottom of a building and installing a finishing panel on the ceiling finishing device. Various techniques have been proposed and used.

The conventional ceiling finishing device consists of a hanger installed on the ceiling, a rectangular carrier bar installed on the hanger, and a configuration that is installed on the carrier bar and is mounted on a T-bar wing surface to which a finishing panel is attached.

The carrier bar and the T-bar are configured to form a support hook at the lower portion of the carrier bar and directly coupled to the T-bar through the support hook, or connect the carrier bar and the T-bar using a connecting clip.

However, the conventional coupling structure of the carrier bar and the T bar is not a structure having a strong bonding force by interlocking with each other, but a bonding structure that is simply suspended in a fitted state, so the bonding strength is very weak. There is a problem in that the bar and the T-bar are easily separated.

In addition, the finishing panel is installed so that the edge is placed on the T-bar. At this time, because it is simply placed on the top of the T-bar, when an external shock such as an earthquake is applied, the finishing panel is immediately separated from the T-bar and falls to the floor, resulting in a safety accident. There is a problem that occurs.

The sound-absorbing auxiliary plate 160 is formed so as to be coupled between the skirt portion 150 and the sound-absorbing plate 110 .

A plurality of sound-absorbing auxiliary parts 170 are formed in the sound-absorbing auxiliary plate 160, and the sound-absorbing auxiliary portion 170 is interlaced with the sound-absorbing portion of the sound-absorbing plate 110, and at the same separation distance as the surrounding sound-absorbing portions 120. Located.

The sound-absorbing auxiliary unit 170 is a sound-absorbing auxiliary plate (160) in which a part of the sound-absorbing auxiliary plate (160) faces the ceiling side from one side of the sound-absorbing auxiliary plate (160) toward the sound-absorbing plate (110) like the sound-absorbing unit (120) of the sound-absorbing plate (110). and a third embossing portion 180 and a fourth embossing portion 190 formed to protrude convexly by a predetermined length toward the rear side of the .

The third embossed portion 180 includes a third sidewall portion 181 and a third bottom portion 185 , and the fourth embossed portion 190 includes a fourth sidewall portion 191 and a fourth bottom portion 195 . is composed of

The third embossing unit 180 and the fourth embossing unit 190 have the same structure as the first embossing unit 130 and the second embossing unit 140 constituting the sound absorbing unit 120, respectively, and the third sidewall The portion 181 and the third bottom 185 and the fourth sidewall 191 and the fourth bottom 195 are respectively a first sidewall 131 and a first bottom 135 and a second The same structure as that of the side wall part 141 and the second bottom part 145 was applied.

The third embossing unit 180 and the fourth embossing unit 190 can apply the same embodiment as all embodiments of the first embossing unit 130 and the second embossing unit 140 described above, and have detailed structures Since it is the same as the description of the first embossing unit 130 and the second embossing unit 140 described above, a description thereof will be omitted.

On the other hand, on the edge side of the sound-absorbing auxiliary plate 160 corresponding to the skirt portion 150, a spacer plate 161 for separating the sound-absorbing auxiliary plate 160 from the sound-absorbing plate 110 by a predetermined distance in a direction that intersects with the sound-absorbing auxiliary plate 160 It is extended by a certain length.

When the separation plate 161 enters and inserts the sound-absorbing auxiliary plate 160 between the skirt unit 150 and the sound-absorbing plate 110 , its outer peripheral surface is in close contact with the inner peripheral surface of the skirt part 150 . Although not shown in the drawings, a thin rubber coating layer may be formed on the outer circumferential surface of the separation plate 161 to prevent slippage with respect to the skirt unit 150 .

The sound-absorbing auxiliary plate 160 is disposed at the rear of the sound-absorbing plate 110 to absorb the noise passing through the sound-absorbing part 120 of the sound-absorbing plate 110 in the spaced space formed between the sound-absorbing plate 110 and the sound-absorbing auxiliary plate 160 A certain portion of the space. It is possible to significantly increase the sound absorption performance by passing the remaining noise to the ceiling side through the sound absorption auxiliary unit 170 .

In addition, it is possible to obtain a very high sound-absorbing and sound-insulating effect by suppressing and blocking the noise reflected from the ceiling from passing to the sound-absorbing plate 110 side.

The seismic reinforcement type ceiling finishing system according to the present invention described above has been described with reference to the accompanying drawings, but this is only an example, and those of ordinary skill in the art will find various modifications and equivalent other embodiments therefrom You will understand that it is possible.

Accordingly, the scope of true technical protection of the present invention should be determined only by the technical spirit of the appended claims.
