Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-combustible partition panel, and more particularly to a partition panel suitable for forming a lightweight fireproof and soundproof partition wall in a high-rise apartment house or a hotel. is there.

b. Conventional technology Conventionally, as a partition panel constituting this kind of lightweight fireproof and soundproofing partition wall, there is a partition panel having a structure as shown in FIGS. 9 and 10 (JP-A-63-27645 and JP-A-63-27645). 63-78942
No.).

The partition panel 1 of this structure is provided with vertical ribs 1b and 1c on the back side of the panel body 1a, and cut grooves 1d on the vertical ribs 1b and 1c, respectively. 3 is provided.

The panel 1 has, for example, a pair of such members, which are erected between the upper slab 2 and the lower slab 5 with a non-combustible sound absorbing material interposed therebetween, and the cut grooves 1d are attached to the upper runner 3 attached to the upper slab 2 by the spring material 4. The upper part is fixed by inserting through the slab, and the lower part is fixed to the lower slab 5 by a conventional means to form a partition wall.

The panel 1 was excellent in workability and was superior in terms of lightness, fire resistance and sound insulation as compared with a concrete driving type. In addition, panel 1 has upper and lower slabs 2,5
The upper runner 3 slides in the spring material 4 in the cut groove 1d to absorb the above-mentioned displacement, thereby preventing the generation of internal stress due to the displacement. It is also excellent in that the occurrence of cracks and destruction of the panel, which tends to occur in such cases, can be effectively prevented.

c. Problems to be Solved by the Invention By the way, the thickness of the teeth of a ceramic cutter used for providing the cutout groove 1d in the noncombustible partition panel 1 is usually about 3 mm. On the other hand, the thickness of the upper runner 3 used for the partition wall is usually about 0.6 to 1.6 mm.

Therefore, if the notch groove 1d is simply inserted into the upper runner 3 as it is, the joining between the upper runner 3 and the panel 1 is incomplete, resulting in rattling.

Therefore, in the conventional panel 1, in order to reliably hold the upper runner 3 in the cutout groove 1d by utilizing the elastic force of the spring material 4, the lower part of the spring material 4 is cut using the adhesive to form the cutout groove 1d. To fix it.

However, this work is time-consuming because it is necessary to hold the spring material until the adhesive cures,
Further, there is a problem that the spring member 4 may come off during transportation or construction of the panel 1.

d. Means for Solving the Problems The present invention has been made to solve such conventional problems, and provided a plurality of vertical ribs on the back surface of the panel body, on the upper portion of these vertical ribs, In a non-combustible partition panel provided with a cutout groove for inserting an upper runner on the building side, when the hanging portion of the upper runner is inserted into the notch groove and the panel is built, the lower end of the hanging portion The notched groove is formed at an angle α with respect to the hanging portion so that the side surface in the middle of the notched groove abuts on the inner side surface and the entrance corner of the notched groove, respectively.

e. Example Hereinafter, an example of the nonflammable partition panel according to the present invention will be described in detail with reference to the accompanying drawings.

1 to 5 show an embodiment of the present invention.

The incombustible partition panel 10 of the present embodiment has a pair of hollow vertical ribs 10b, 10b on both side edges of the rear surface of the flat panel body 10a.
Having. Notch grooves 10c, 10c are formed on the upper portions of the vertical ribs 10b, 10b, respectively. These notches 10c, 10c are formed so as to form an appropriate angle α with the hanging portion 12a of the upper runner 12 fixed to the upper slab 11. By providing the angle α in this manner, the panel 10 has the upper slab 11 and the lower slab 11 as described later.
13, the lower part 12 of the upper runner 12 at two points A and B in the notch groove 10c as shown in FIG.
a and is in a semi-fixed state with respect to the upper runner 12. In addition, by setting the angle α to be large, a force is exerted to bend the hanging portion 12a of the upper runner 12 further inward, so that the semi-fixed state between the panel 10 and the upper runner 12 can be further strengthened. .

As described above, the semi-fixed angle α is defined as a where the dimension of the hanging portion 12a of the upper runner 12 to enter the notch groove 10c is b, the groove width of the notch groove 10c is b, and the plate thickness of the upper runner 12 is t.
Then Can be derived from the relationship.

 In this embodiment, it is preferable that t ≒ 0.5 to 3.2 mm, a ≒ 10 to 100 mm, b ≒ 2 to 20 mm, and α ≒ 3 to 20 °.

FIG. 3 shows a state in which the panel 10 of the present embodiment is built in the upper runner 12.

When the panel 10 is pushed upward while being inclined so that the notch groove 10c faces directly upward, the lower part of the upper runner 12
Inserted into 12a. At this time, since the notch groove 10c faces right above, the panel 10 can be smoothly inserted into the upper runner 12. After insertion, panel 10
As shown in FIG. 2, the hanging portion 12a of the upper runner 12 comes into contact with the notch groove 10c at two points A and B, as shown in FIG. As a result, the panel 10 is held in the upper runner 12 in a semi-fixed state.

As is clear from the above, according to the present invention, since the panels 10 can be joined to each other in a semi-fixed state only by inserting the panels 10 into the upper runners 12 and standing up, the spring material as conventionally used becomes unnecessary. .

The non-combustible partition panel 10 can be formed, for example, by extrusion molding of fiber-reinforced gypsum mortar or fiber-reinforced cement mortar. In addition, the vertical ribs are not limited to two at both end portions of the panel body 10a, and a plurality of vertical ribs may be provided at an intermediate portion thereof. The vertical rib 10b is not limited to a hollow shape and may be a solid. Similarly, the panel body 10a is not limited to a solid,
One or more hollow portions may be provided.
Furthermore, the cutout groove 10c is not limited to the shape shown in FIG. 1, but may be another shape corresponding to the shape of the upper runner 12.

11 is an upper slab, 12 is an upper runner attached to the upper slab 11, and its thickness is a channel steel having a thickness of about 1 to 1.6 mm. When it is desired to increase the interval between the panels 10 facing each other, the upper runners 12 may be configured with a suitable interval using a pair of angle irons. 13 is a lower slab, 14 is a wall or a column, 15 is a lower runner attached to the lower slab 13, and its thickness is an angle steel having a thickness of about 1 to 1.6 mm, but is not particularly limited to the angle iron.

16 is a non-combustible sound absorbing material such as glass wool or rock wool disposed between the panels 10 and 10 facing each other;
Is a mat such as rock wool that fills the gap between the upper and lower slabs 11, 13 and the wall or column 14 and the panel 10, and serves as a buffer between the upper and lower slabs 11, 13 and the panel 10 in the event of an earthquake or the like. 18 is a liner for height adjustment laid under the panel 10,
Reference numeral 19 denotes a sealing material provided on the front side of the panel 10.

The partition panel 10 has an upper runner 12 inserted into each notch groove 10c to be in a semi-fixed state, and a lower portion thereof is fixed to the lower runner 15 using screws or the like. In order to further enhance the sound insulation performance, another flat plate may be added to the surface of the panel 10.

 FIG. 6 shows a second embodiment of the present invention.

In this embodiment, the hanging portion 12a of the upper runner 12 is machined at an obtuse angle. In addition, notch grooves 10
c was processed parallel to the panel body 10a. Also in this embodiment, the notch groove 10c and the hanging portion 12a of the upper runner 12 come into contact at two points C and D as shown in FIG. 6, so that the same operation and effect as in the above embodiment can be obtained.
