KR200189571Y1 - Plaster board fireproof construction by shaft wall - Google Patents

Abstract

The present invention relates to a gypsum board refractory structure for a shaft wall, and more particularly, to a fire structure in which a high temperature of the shaft wall is not transmitted to the inside by a metal stud when a fire occurs.

In order to prevent the high heat of the shaft wall from being transmitted to the inside of the passage through the metal studs, the present invention can be firmly installed by fixing the blades of the metal studs in the space secured against the tethered gypsum board. By preventing the studs from being exposed to the shaft wall side, it is possible to prevent the degradation of fire resistance due to heat transfer through the metal studs.

Description

Plasterboard fireproof structure for shaft wall {Plaster board fireproof Construction by shaft wall}

The present invention relates to a gypsum board fireproof structure for shaft walls, in particular vertically

The present invention relates to a gypsum board fireproof structure attached to a passage or a duct of a lift.

As is well known, a fireproof structure having fire resistance is installed on an inner wall of an elevator passage or a duct to protect an occupant in an elevator from heat generated in a fire.

An example of the construction of such a representative shaft wall can be seen by US Patent No. 4,353,192 (name of the invention: refractory metal stud) and Korean Patent Registration No. 0,151,171 (name of the invention: shaft wall and horizontal metal stud). These prior patents all use metal studs between adjacent gypsum core boards, and the metal studs are exposed to the shaft wall side or the shaft wall side and the inner center side.

Therefore, the prior patents have a problem in that the heat of the shaft wall is transferred to the inside of the elevator through the metal stud when the fire occurs, the fire resistance is reduced.

The object of the present invention is to provide a gypsum board fireproof structure for shaft walls that can greatly improve the fire resistance by preventing the external exposure of the metal studs to prevent the fire performance is degraded due to the exposure of the metal studs to solve this problem. have.

Referring to the present invention in more detail with reference to the accompanying drawings as follows.

All.

In the known shaft wall fireproof structure in which the gypsum boards 4, 4 ', 5 used to obtain fire resistance as shown in FIG. 1 are provided with metal studs 1 fixed with screws 11 or the like. In addition, the four ends of the tapered gypsum board (2,3,2`, 3 ') face each other, and the space part 10 is provided so that the blade piece 9 of the metal stud 1 is located.

In the present invention, the high heat is applied from the gypsum board (4,5,4 ') to the tapered gypsum board (2,3,2', 3 ') in the shaft wall during the fire. (1) Since the tapered gypsum board (2.2 ') surrounding the blade (9) of the metal stud (1) blocks the heat transferred to the blade (9), the fire resistant structure due to the heat transfer of the metal stud (1) Performance degradation is prevented. In addition, more preferably, the interior of the space 10 in which the blade piece 9 of the metal stud 1 is positioned may be filled with a filler 6 having fire resistance to further improve fire resistance. . In this embodiment, the tapered gypsum boards 2, 3, 2 'and 3' are inserted into and fixed to the blade 9 of the 'CH' type metal stud 1, and the tapered gypsum boards 2 and 2 ' Since the tapered gypsum boards 3 and 3 'are bonded with an adhesive or double-sided tape, the tapered gypsum boards 2, 3, 2' and 3 'can maintain a fixed structure in a very stable state.

And the gypsum board (4, 4`) is fixed to the metal stud (1) with a screw 11, the gypsum board (5) is a gypsum board (4, 4 ') to achieve a secure fastening state. In addition, in the embodiment shown in Figure 1 is shown an example using the 'CH' type metal stud (1), 'I' type metal stud (1) may be used, this embodiment is shown in FIG. As can be seen here, the present invention is a tapered gypsum board (3, 3 ') is fixed to the metal stud (1') wing 9 and the tapered gypsum board (2, 2 ') adhesive or double-sided tape By attaching to the gypsum boards 3, 3 ′, the blade 9 of the metal stud 1 ′ is fitted into the space 10 formed by the tapered gypsum boards 2, 3, 2 ′, 3 ′. Since the gypsum board (2, 3, 2 ', 3') and the metal stud (1 ') is fixed in a stable state, in this case as well, as shown in Figure 1 through the metal stud (1) Since the tapered gypsum board (2.2 ') surrounding the blade piece 9 of the metal stud 1 is blocked from the heat transferred to the blade piece 9 of the metal stud 1, fire resistance due to heat transfer of the metal stud 1 is prevented. The performance degradation of the structure can be prevented, and the fire resistance of the interior of the space portion 10 in which the blade piece 9 of the metal stud 1 is located, as in the embodiment shown in FIG. The filling (充 塡 物) (6) can be further enhanced by the fire that is to be filled as well.

In this embodiment also the other end of the 'I' type metal stud (1 ') gypsum board (4, 4`) is fixed to the metal stud (1) with a screw 11 and gypsum board (5) screw Or it is fixed to the gypsum board (4, 4 ') by a method such as a tacker, adhesive or double-sided tape to maintain a solid fastening state.

In the present invention, as shown in FIG. 3, when the space is inevitably formed at the ends of the gypsum boards 4 and 5 and the gypsum boards 4 and 5 ', the space portion (as shown in FIGS. 10) the blade 9 of the metal stud 1 is fixed, but the space formed at the junction of the gypsum boards 4, 5, 4`, 5 'is filled with a fire resistant sealant 7 having heat resistance. In addition, by bonding the metal stud (1) and gypsum board (4,4`) with the heat-resistant adhesive tape (8) to zoom and to ensure a solid fastening state while maintaining the fire resistance performance.

In addition, shown in Figure 4 the space portion 10 formed by the present invention.

In addition, in the present invention, a 'di 귿' type metal stud (1 '') is used to fix the gypsum board (2,3,4,5) at the end, and the tapered gypsum board (2,3) in the direction of the shaft wall. To form a space portion 10 corresponding to 1/2 of FIGS. The inner gypsum board 4 is fixed to the metal stud 1 '' with screws 11, and the gypsum board 5 is fixed to the gypsum board 4 by means of screws or tackers, adhesives or double-sided tape, etc. It will be able to secure the fastening state.

In this way, the present invention inserts the blade 9 of the metal studs (1,1 ', 1' ') into the space obtained by facing the tapered gypsum boards (2,3,2', 3 '), and thus the shaft in case of fire Since the tapered gypsum board (2.2 ') surrounding the blade (9) of the metal stud (1) is blocked by the heat transmitted to the blade (9) through the metal stud (1, 1', 1 '') of the wall It is possible to prevent the performance degradation of the refractory structure due to the heat transfer of the metal stud (1), more preferably of the space portion 10 in which the blade piece 9 of the metal stud (1, 1 ', 1' ') is located. It is possible to further improve the fire resistance by filling the filling (충전 物) having a fire resistance performance inside. In addition, in the present invention, even when the metal stud 1 is exposed at the gypsum board 4, 5, 4`, 5 'joint part, the fire resistant adhesive tape 8 and the fire resistant sealant 7 having fire resistance are required. There is a useful effect that can be applied to maintain a high fire resistance performance.
