Abstract

PROBLEM TO BE SOLVED: To prevent an upper mounting structure from being damaged by supporting the upper part of an incompressible wall material and a slide spacer slidably on the inside of a runner. SOLUTION: An upper runner 2 with a top plate 2a of which width is equal to the thickness of a composite partition wall 1 and both side plates 2b is fixed to the lower surface 4 of an upper floor slab as the structural body of a building. Also a slide spacer 9 is provided with a top plate 9a and side plates 9b1 and 9b2. Then the side plate 9b1 is fixed to the side surface of an incompressible wall material 7 using a latch 10, and the upper part of an incompressible wall material 8 is stored between the side plates 9b1 and 9b2. In addition, the upper runner 2 is brought in contact with the partition wall 1 through the side surface of the wall material 7 and the spacer 9. By this, even if a vibration is applied to the building and the structural body is deformed, or a force is applied to the contact part, freedom to move in the vertical direction is restricted because the top plate 9a is brought in contact with the top plate 2a. On the other hand, it is free to slide in the horizontal direction so that the damage to the upper mounting structure can be prevented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described with reference to FIGS. In this example, a structure in which a composite partition wall including an incompressible wall material and a compressible wall material is arranged between the lower surface (ceiling) of the upper floor slab and the lower floor slab will be described. FIG. 1 is a partial cross-sectional perspective view in which a composite partition wall is attached between the upper floor slab and the lower floor slab of the building,
FIG. 2 is a side sectional view of the upper part showing the mounting structure of the composite partition wall. 3 is a plan sectional view of the composite partition wall taken along the line AA of FIG.

As shown in FIG. 1, the composite partition wall 1 is formed by superposing a compressible wall material 7 and an incompressible wall material 8.
The compressible wall material 7 is made of glass wool, rock wool, ceramic fiber blanket or the like as its material. Further, as the non-compressible wall material 8, ALC,
Extruded plates, PC plates, etc. are used.

Lower surface 4 of the upper floor slab, which is the structure of the building
The upper runner 2, which is a long metal rail, is fixed by using fasteners 6 such as nails. As shown in FIGS. 1 and 2, the upper runner 2 includes a top plate 2 having a predetermined width.
It is composed of a and side plates 2b and 2b whose both side edges in the width direction are raised, and has a U-shaped cross section. Side plates 2 on both sides
The inner surface of the top plate 2a on which the b and 2b are raised has a width that is the sum of the thickness of the incompressible wall material 8 and the width of the slide spacer 9 described later.

A lower runner 3, which is also a long metal rail, is fixed to the upper surface of the lower floor slab 5 by using a nail (not shown). As shown in FIG. 1, the lower runner 3 is composed of a plate body 3a and a side plate 3b whose one side edge is raised.

A slide spacer 9 holding a space for mounting the compressible wall material 8 is fixed to the upper side surface of the incompressible wall material 7. The slide spacer 9 is a top plate 9a.
And side plates 9b1 and 9b2 whose both side edges are raised, and is a bracket having a U-shaped cross section. One side plate 9b1 is longer than the other side plate 9b2, and the same side plate 9b1 is used for the incompressible wall material 7
Fasteners such as nails, screws, bolts and staples on the side of the
It is stopped using 0. The width between the side plates 9b1 and 9b2 of the slide spacer 9 is substantially the same as the width of the compressible wall member 8 or slightly narrower. The side plates 9b1 and 9b
The width between b2 is made larger than the width of the compressible wall material 8, a reinforcing member surrounding the upper part of the compressible wall material 8 is provided, or the spacer 3 is arranged between the compressible wall material 8 and the side plates 9b1, 9b2. You can also

The material of the upper runner 2, the lower runner 3, and the slide spacer 9 is selected from rolled steel for general structure, hot-dip galvanized steel plate, lightweight steel for general structure, etc. For example, a reinforced synthetic resin or the like can be used.

The incompressible wall material 8 and the compressible wall material 7 are overlapped with each other, and the upper end of the incompressible wall material 8 is fitted between the side plates 2b, 2b of the upper runner 2. On the other hand, the lower end is positioned so as to be pressed against the side plate 3b of the lower runner, and the lower end of the incompressible wall material 7 is fixed by using the auxiliary metal fitting 14. At this time, a gap is created between the upper end of the non-compressed wall material 7 and the top plate 2a of the upper runner 2, while the top plate 9a and the side plate 9b2 of the slide spacer 9 and the top plate 2a of the upper runner 2 and The height of the non-compressed wall material 7 and the fixed position of the slide spacer 9 are set so as to contact the side plates 2b, respectively.

Incidentally, when the incompressible wall material 7 and the compressible wall material 8 are built in the structure of the building, the adjacent wall materials are arranged so that the front and back are reversed, that is, FIG.
As shown in, the incompressible wall material 7 and the compressible wall material 8 are arranged so as to alternate with each other. Then, after that, the first outer board 11 and the second outer board 12, which also serve as fireproof coatings and decorative boards, are further fixed on both sides with metal fittings or the like to complete the construction of the composite partition wall 1.

In the composite partition wall 1 constructed as described above, the upper runner 2 on the lower surface side of the upper floor slab and the composite partition wall 1 are in contact with each other through the side surface of the incompressible wall material 7 and the slide spacer 9. . Therefore, even if vibration is applied to the building and the structure is distorted and a force is applied to the contact portion between the upper end of the composite partition wall 1 and the structure, the slide spacer 9 is prevented from sliding and being destroyed. . In particular, in this embodiment, since the top plate 9a of the slide spacer 9 is in contact with the top plate 2a of the upper runner 2, the freedom to move in the vertical direction is limited, while the slide plate 9 slides freely in the horizontal direction. Therefore, it is possible to construct the composite partition wall 1 in which the mounting portion is not easily damaged by an earthquake or traffic vibration.

Further, since the compressible wall material 8 can be fixed to the incompressible wall material 7 by using the slide spacer 9, when these are inserted into the upper runner 2, the incompressible wall material 7 and With the compressible wall material 8 combined, it can be easily stood up in the structure of the building, and the construction efficiency can be improved.

There is a possibility that the slide spacer 9 may rub against the upper runner 2 due to the vibration of the building to generate a friction noise. Therefore, if a sliding member having a small friction coefficient is interposed between the upper runner 2 and the slide spacer 9 by sticking a fluororesin tape to the slide spacer 2 or sandwiching a Teflon plate or the like, the friction noise is reduced. Occurrence can be prevented.

In the above embodiment, the incompressible wall material 7 is fixed by using two slide spacers 9 for each incompressible wall material 7, but this number is the same as that of the incompressible wall material 7. It can be arbitrarily selected according to the width and the like. Further, by forming the slide spacer 9 in a laterally long shape like the upper runner 2, it is possible to provide one slide spacer. Furthermore, although the slide spacer 9 is fixed to the incompressible wall material 7 in this embodiment, the incompressible wall material 7 and the slide spacer 9 are fixed.
The compressible wall material 8 to which is fixed may be fitted separately, and in this case, both are not necessarily fixed.

[0022]

As described above, depending on the upper mounting structure of the composite partition wall of the present invention, the slide spacer causes the composite partition wall to slide with respect to the runner provided on the lower surface of the structure of the building. Even if the structure is distorted by traffic vibration or traffic vibration, the force applied to the upper part of the composite partition wall can be released, and damage to the same part can be prevented.
