Description

[Detailed Description of the Invention] The present invention relates to a smoke-proof wall that is formed below the ceiling of an indoor opening of a building and temporarily blocks smoke flowing along the ceiling in the event of a fire.

A conventional and common structure of this smoke-proof wall is one in which a non-combustible board or semi-non-combustible board (hereinafter collectively referred to as a non-combustible board) such as plate glass is held by a wooden frame fixed to the lower part of the ceiling of the opening.

However, this structure is dangerous because in the event of a fire, the wooden frame will be destroyed and the non-combustible board will fall.

On the other hand, a structure in which the noncombustible plate is held by a metal frame made of aluminum or the like has problems in that it does not match in design with a room interior that is made of wood or has a wood-like interior, and is also expensive.

Therefore, the present invention uses a wooden frame as a frame body, and has a structure in which the noncombustible board does not fall even if the wooden frame is burnt down. The holding fittings to be held are fixed, the wooden frame is installed so that the holding fittings are buried between the walls on both sides of the lower part of the ceiling surface in the opening, and the noncombustible board is fitted and supported by the holding fittings at its side edges. It has a structure in which it is housed and fixed within a wooden frame.

Embodiments of the present invention will be described below with reference to the drawings.

As shown in Fig. 1, the smoke-proof wall is a concrete frame A that forms the ceiling of an indoor opening and one side wall, and a partition wall B that forms the other side wall. Can be installed by joining.

The wooden frame 1 consists of side frames 11, 12, an upper frame 13, and a lower frame 14, and the mutually abutting ends are fixed with wood screws to form a frame body, as shown in FIGS. 2 and 7. Each frame 11.
The plate glass 2 is fitted and held by the grooves provided at 12, 13, and 14.

As shown in FIGS. 5 and 6, a metal insert member 61 having a screw hole is embedded in the upper part of the side wall A2 of the building body at a position close to the ceiling, and a metal plate 7 is installed in the side wall A2. A plate glass holding fitting 31 having a U-shaped cross section is screwed therebetween with a bolt 51.

On the other hand, the plate 7 and the holding fittings 31 are attached to the side frame 11.
A hole 111 that fits with the outer peripheral surface of the side frame 1 is provided.
1 is connected to the plate 7 and the holding fitting 31 through the hole 111.
It is attached to the side wall part A2 in a state where it covers and fits.

An insert member 62 similar to the insert member 61 described above is embedded in a position corresponding to the flat end of the side frame 11 in the side wall portion A2.

A hole 112 is provided in the corner of the wooden frame formed by the side frame 11 and the lower frame 14, into which the plate glass holding fitting 32 is inserted and stored. It is screwed onto the side wall portion A2 with bolts 52.

As shown in FIG. 8, the holding fitting 32 has a support portion 321 formed inside the U-shaped portion to support the bottom side end of the glass plate 2. As shown in FIG.

The other side frame 12 is also screwed onto the partition wall B by the same means as described above, and also incorporates holding fittings identical to the holding fittings 31 and 32 at corresponding locations.

The outer periphery of the plate glass 2 held in the main frame 1 is fitted into the groove of the wooden frame 1, and as shown in FIG. There is.

The partition wall B side also has the same structure.

In addition, both ends of the bottom of the plate glass 2 have a fifth
As represented in the figure, it is supported by a support portion 321 of the holding fitting 32.

When assembling the smoke-proof wall, first, plate glass holding fittings 31 are screwed into predetermined positions facing each of the side wall portion A2 and the partition wall B of the frame.

Next, the side frames 11 and 12 are fitted into the holding fittings 31, respectively, and adhered to the metal plate 7 with an adhesive if necessary.

Thereby, the side frames 11 and 12 are attached to the side wall portion A2 and the partition wall B, respectively.

Next, the upper frame 13 is joined to the ceiling part A1 of the frame, and both ends thereof are inserted into the upper end abutting parts of the side frames 11 and 12, and fixed with wood screws.

Next, insert the plate glass 2 from below the both side frames 11°12,
The holding fitting 32 and the side frame 11, with both ends of the bottom supported by the support plate 321 of the holding fitting 32,
12 to port 1 on side wall A2 and partition wall B, respectively.
2. Screw on.

The installation is then completed by fixing the lower frame 14 at both ends to the lower ends of the side frames 11.12 with wood screws.

In this way, the smoke-proof wall of the present invention can be installed with good workability, and by using a wooden frame as the frame for the plate glass, it can be used in general houses in terms of interior design and is well-matched with others. Since the plate glass is held within the wooden frame by the holding metal fittings, even if the wooden frame is destroyed in the event of a fire, there is no risk of it falling, and firefighting operations can be carried out safely.

In addition, since the holding metal fittings are buried within the wooden frame and are not exposed, the appearance is extremely simple.
