Description

[Detailed description of the invention] [Purpose of the invention] Industrial field of application The present invention relates to a partition that separates the interior of a building such as an apartment building or an office building, and more specifically to a partition that has a fire-resistant structure.

BACKGROUND ART Fire-resistant partitions in which panels are constructed from fire-resistant materials such as asbestos calcium silicate and asbestos cement boards have been known. Usually, the surface of this panel is covered with a surface plate such as a colored galvanized iron plate. As shown in FIG. 7, a conventional general fireproof partition has a floor rail A on the floor and a ceiling rail B on the ceiling, and the panel C is installed between the rails, similar to a window shoji screen. The upper and lower rails were generally made of metal.

Problems that the invention aims to solve Panel C itself is made of fire-resistant material as mentioned above, so it is fire-resistant, but if it is simply built between rails A and B, the height of the panel cannot be adjusted to match the floor and ceiling. Since it is not possible to match the spacing between panel C and the ceiling as shown in Figure 7, rails A and B are connected to both sides of panel C, and heat from one side is transferred to the gap and the metal. The disadvantage was that the heat was transmitted to the other side through the rail, resulting in high temperatures as well. In order to avoid this, it was necessary to cover the rail material with a separate heat insulating material.

The purpose of the present invention is to provide a fire-resistant partition that blocks the transmission of fire and heat from the parts where the panels are attached to the floor and ceiling.

In this specification, fire resistance does not necessarily mean only something that satisfies the fire resistance performance standards of the Building Standards Act. It means that the material is flammable, and it also includes performance to the extent of being non-flammable.

[Structure of the invention] Means for solving the problem The present invention has a panel 10 as shown in FIG. As shown, it is a fireproof partition installed with two backing materials facing each other, and a notch 13 cut out at right angles is formed at the top and bottom of the backing material 11 of the panel 10 so as to have a horizontal surface 13a and a vertical surface 13b. On the other hand, a support member 18 having fire resistance and a rectangular cross section with a constant width is fixed to the floor 16, and a mounting member 19 having a rectangular cross section and having fire resistance as well and having a width equal to the width of the support member is fixed to the ceiling 17, A panel is placed between this support material and the mounting material, and the horizontal surface 13a of the cutout on the lower side of both panels is connected to the support material 1.
8, the vertical surface is brought into contact with the supporting material, and the vertical surface 13b of the upper notch is brought into contact with the mounting material 19 and fixed.

If there is a gap between the tip of the mounting material 19 and the horizontal surface of the panel cutout 13 as shown in the figure,
It is desirable to fill this with a fireproof material 27, and the supporting material and mounting material are the fireproof board 20 and the sandwiching plates 21 and 2 that sandwich it from both sides and fix it to the floor or ceiling.
2 is desirable.

Function: Since fire-resistant supporting materials 18 and mounting materials 19 are placed at the upper and lower ends of the panel 10, respectively, it is possible to prevent fire and heat from being transmitted from these parts to the adjacent room, creating a fire-resistant partition. It can have sufficient performance. Further, since the panel is fixed by placing the horizontal surface 13a of the notch 13 on the tip of the mounting portion 18, the panel mounting operation becomes easy. Fire resistance performance can be improved by making the width of the supporting material and the mounting material larger than the thickness of both the two panels 10, 10, and attaching the panel 10 between the supporting material and the mounting material as shown in FIG.

Example FIG. 2 shows a panel 10 used in this example, in which a backing material 11 made of an obsidian foam board (obsidian foam grains formed into a plate shape with an appropriate binder) is coated with a front surface made of a colored galvanized iron plate. A face plate 12 is attached. As the backing material 11, in addition to the above-mentioned obsidian foam board, any fire-resistant material such as asbestos calcium silicate, asbestos cement board, etc. can be used. It goes without saying that other metal plates can also be used for the surface plate 12. This panel 1
At the upper and lower ends of the backing material 11 of 0, rectangular notches 13, 13 are formed at right angles so as to have a horizontal surface 13a and a vertical surface 13b. Furthermore, in this embodiment, a similar notch 14 is also formed on the side of the panel 10, as shown in FIG. The surface plate 12 covers the entire surface, upper and lower surfaces, and side surfaces of the backing material 11, that is, the back surface 15 of the backing material 11.
It is provided so as to cover the entire surface except the inside of the notch 13, and the tip of the portion covering the lower end surface is bent to form the hooking portion 12a.

The two panels 10 are installed between the floor 16 and the ceiling 17 with their back surfaces 15 facing each other to partition a room as shown in FIG. , a mounting material 19 is fixed to the ceiling 17, and panels 10, 10 are installed and fixed between them. Both the supporting member 18 and the mounting member 19 are made by sandwiching a fireproof plate 20 such as an asbestos calcium silicate plate of a predetermined width between metal sandwiching plates 21 and 22 from both sides. Asbestos cement board instead of asbestos calcium silicate,
Of course, other fire-resistant materials such as obsidian foam board may also be used.

The heights from the floor and ceiling surfaces, that is, the distance from the tip of the support material 18 to the tip of the mounting material 19 are the horizontal plane 13 of the lower cutout 13 of the panel 10.
a is placed on the tip of the support member 18, there is no or a slight gap between the horizontal surface 13a of the upper notch 13 and the tip of the attachment member 19. Furthermore, in this embodiment, the width of the supporting member 18 and the mounting member 19 (including the sandwiching plates 21 and 22) is
The width of the space formed by the notch 13 of 0,
That is, the distance is set to be equal to the distance between both vertical surfaces 13b, 13b, but the distance is not limited to this. Particularly, as shown in FIG. 6, in order to improve fire resistance performance, when the panels 10, 10 are installed with a gap between them, both the supporting material and the mounting material must be wide. In that case, in this embodiment, it is sufficient to simply use a wide fireproof board 20 or to stack other fireproof boards, and no other extra members are required, so it is easy to achieve the required fireproof performance. Can be set to a value.

The sandwich plate 21 has a vertical part 21a in contact with the surface of the fireproof board 20, a horizontal part 21b bent at a right angle so as to contact the floor 16 at the bottom, and a horizontal part 21b bent at a right angle from the horizontal part in parallel with the vertical part 21a. It has a cross-sectional shape having a support portion 21c,
Screw 23 screwed into the floor 16 from the horizontal part 21b
It is fixed to the floor 16 by. In this embodiment, the fireproof board 20 is bonded to the floor 16 with an inorganic adhesive whose main component is water glass. Sandwich plates 21, 21 arranged on both sides of this fireproof plate 20
are connected by tie rods 24 to sandwich the fireproof plate 20, but the fireproof plate 20 and the vertical portion 21a may be bonded together using the adhesive described above. The structure of the ceiling side sandwiching plate 22 and its attachment to the ceiling 17 are not particularly different from those on the floor side. In this embodiment, the width of the horizontal portion 22b of the sandwich plate 22 is made wider than that of the floor side sandwich plate 21b, but there is no essential difference.

The panel 10 has a horizontal surface 1 of a cutout 13 on its lower side.
3a on the tip of the support member 18, and the vertical surface 13b is brought into contact with the side surface of the support member 18, and the vertical surface 13b of the notch 13 at the upper end is placed on the vertical portion 2 of the mounting member 19.
2a and insert the pin screw 25 into the sandwich plate 22.
Pass through and secure. At this time, the ceiling cover 26 is attached between the surface plate 12 of the panel 10 and the support part 22c of the sandwich plate 22, and the space between the ceiling cover 26 and the vertical part 22a of the sandwich plate 22 is filled with rock wool 27. . Of course, other fireproof materials may be used instead of rock wool. The pin screws 25 are screwed in from above the ceiling cover 26 and fix the ceiling cover 26 at the same time. Baseboard 2 on the floor side
8 between the vertical part 21c of the plate 21 and the hooking part 12a.
and secure it with the tuft pin screw 25. Similarly, rock wool is filled between the baseboard 28 and the vertical portion 21a of the sandwich plate 21. In this embodiment, since the gap between the sandwich plate 21 and the baseboard 28 is made narrower than the gap between the ceiling side sandwich plate 22 and the ceiling cover 26, the hooking portion 12a is attached to the surface plate 12 of the panel 10.
is provided, and the upper end of the baseboard 28 is bent at a right angle, and the tip thereof is hung on the latching part 12a to hold down the panel 10, but the floor side may also be held in the same manner as the ceiling side. In that case, it goes without saying that it is not necessary to form the hooking portions 12a on the surface plate 12.

The other panel 10 is attached in the same way, but
In this case, it is difficult to fill the space between the mounting material 19 and the horizontal surface 13a with rock wool 27 later, so the following procedure is used. First, measure the thickness of the rock wool 27 to be filled from the previously attached panel 10, and then fill the rock wool 27 with this thickness.
7 is prepared and adhered to the mounting material 19 or the notch of the panel to be attached later with water glass or the like, and fixed in the same manner as the previously attached panel.

The wall end of the room is also fixed in exactly the same structure as the ceiling, as shown in FIG. In addition, the intermediate contact portions between the panels are joined by appropriate means without any gaps.

As described above, the panels 10, 10 are attached to the support member 18,
It is attached between the mounting members 19 to partition a room, but if the floor 16 is not horizontal, a liner 50 made of an asbestos calcium silicate plate or the like is attached to the tip of the support member 18 at an angle as shown in FIG. Accordingly, the sandwiching panels 10 are installed so as to be vertically aligned.
In this embodiment, a gap is formed between the horizontal portion 13a of the upper notch 13 of the panel 10 and the tip of the mounting member 19, so that adjustment can be made to the inclination of the floor surface. Panel 10 and support material 18 to be installed later
The method for attaching the liner 50 interposed therebetween is also carried out in the same manner as described above.

As described above, the fire resistance can be improved by increasing the thickness of the supporting member 29 and the mounting member 30, as shown in FIG. 6, so that the space between the panels 10 and 10 is wide. In this case, it is desirable to fill the space between the panels with rock wool, but the fire resistance is improved even if nothing is filled. Support material 29, mounting material 3
If 0 alone has sufficient fire resistance, there is no need for fire resistant materials such as rock wool on both sides as shown in Figure 1, and ceiling covers and baseboards are simply installed as needed for aesthetic reasons. That's fine.

[Effects of the invention] As explained in detail above, in this invention,
Since the structure is such that the fire-resistant panel is installed between the fire-resistant support material fixed to the floor and the mounting material fixed to the ceiling, it is possible to create a fire-resistant structure without any gaps from the floor to the ceiling, improving fire-resistant performance. be able to.

In addition, the present invention has rectangular notches formed on the top and bottom of the backing material of the panel, and the horizontal surface of the lower notch is placed on the tip of the support material, which facilitates the installation work of the panel.

Furthermore, since the panel is installed so that the vertical surface of the notch is in contact with the vertical part of the supporting material and mounting material, the fire resistance performance can be further improved simply by widening the width of the supporting material and mounting material. Fire resistance performance can be easily obtained. If the supporting material and the mounting material are configured such that the fireproof plate is sandwiched from both sides by sandwiching plates, the width can be easily increased, and the fireproof performance can be easily improved.
