Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the present specification and the drawings, components having substantially the same functional configuration are designated by the same reference numerals, so that duplicate description will be omitted.

(First Embodiment)
1 and 2 show the wall structure 1 according to the first embodiment of the present invention. The wall structure 1 is a door boundary wall that separates a space divided by a floor slab S into two sections P in a hierarchical building such as an apartment house. The building is not limited to an apartment house, and may be used as a hospital or an office. Further, the building is not limited to a hierarchical structure and may be a one-story building. Further, the wall structure 1 is not limited to the door boundary wall, and may be used as a partition wall.

In particular, as shown in FIG. 2, the wall structure 1 has a first finishing material 31 and a second finishing material 32 facing the two compartments P, respectively, and a first finishing material 31 and a second finishing material 32. A steel base material 4 including a runner 5, a stud 6, and a steady rest 7 that supports the wall thickness direction X, and a ceramic wool 9 arranged between the first finishing material 31 and the second finishing material 32. ,have.

The finishing materials 31 and 32 are, for example, gypsum board, rock wool board, calcium silicate board, ALC board (lightweight cellular concrete board cured by high temperature and high pressure steam) or GRC board (cement mortar and glass) formed into a substantially flat plate shape. It is a fireproof plate that exhibits a predetermined heat insulating performance such as a composite plate with fibers). The finishing materials 31 and 32 can have a laminated structure of a plurality of refractory plates. In this case, the same type of refractory plates may be stacked, or different types of refractory plates may be stacked. The finishing materials 31 and 32 are joined to the stud 6 by screws, for example. Specifically, of the plurality of refractory plates, the innermost refractory plate is joined to the stud 6 by a screw, and the other refractory plates are joined to the innermost refractory plate by staples and an adhesive. The means for joining the refractory plate to the stud 6 is not limited to screws, and means such as nails may be used. Further, the means for joining the refractory plates to each other is not limited to staples and adhesives, and for example, double-sided tape can be used for joining.
A floor plate or the like may be interposed between the stud 6 and the finishing materials 31 and 32.

The steel base material 4 can be assembled, for example, based on the standard defined by JIS A 6517. Specifically, the steel base material 4 includes a runner 5, a stud 6, and a steady rest 7 as described above. The runner 5 is a rail-shaped member fixed to the floor slab S and extending in the wall width direction Z at the upper and lower ends of the wall structure 1. The stud 6 is supported by the runner 5 and extends in the height direction Y, and is joined to the finishing materials 31 and 32. The steady rest 7 extends in the wall width direction Z and connects the studs 6 adjacent to each other in the wall width direction Z. As shown in the illustrated example, in the wall structure 1, a plurality of studs 6 are arranged in the wall width direction Z, and a plurality of steady rests 7 are arranged in the height direction.

As a more specific configuration, for example, the stud 6 may be formed of a thin steel plate having a thickness of, for example, about 0.8 mm, and may be a long groove-shaped member in a cross section (XX cross section). Further, the steady rest 7 penetrates the through hole 63 provided in the stud 6 to prevent the stud 6 from swinging. The steady rest 7 is a long member having a groove shape in a cross section (XY cross section), for example, formed of a thin steel plate having a thickness of about 1.2 mm. The steady rest 7 extends so as to be parallel to the floor slab S and the runner 5. The steady rest 7 is arranged in two rows in the height direction Y, but the steady rest 7 may be arranged in at least one row.

The steel base material 4 of the wall structure 1 of the present embodiment employs a so-called common stud method, and a plurality of studs 6 are arranged in a row along the wall width direction Z, and the wall thickness of each stud 6 is increased. The first finishing material 31 and the second finishing material 32 are fixed to both sides of the direction X, respectively.
By adopting the common stud method, the thickness of the wall structure 1 in the wall thickness direction X can be reduced.

Ceramic wool 9 is obtained by laminating ceramic fibers and forming a needle-processed felt-like heat insulating material into a blanket shape. Ceramic wool 9 has fire resistance. In the present embodiment, the ceramic wool 9 is arranged in the space V surrounded by the first and second finishing materials 31, 32, the studs 6 adjacent to each other in the wall width direction Z, and the steady rest 7. The plurality of spaces V are arranged in a matrix on the surface of the wall structure 1 on the surface including the wall width direction Z and the height direction Y. The ceramic wool 9 is cut into blocks so as to fit in each space V.
In the illustrated example, of the ceramic wool 9 blocks, the middle block 92 and the upper block 93 are supported by the steady rest 7.

Here, in the wall structure 1, the blocks of ceramic wool 9 are not arranged in all the spaces V surrounded by the finishing materials 31, 32, the studs 6, and the steady rest 7. More specifically, the block of ceramic wool 9 is not arranged in the space V adjacent to the space V in which the blocks 91, 92, 93 of the ceramic wool 9 are arranged. That is, one block of ceramic wool 9 is arranged in each space V so as to be placed one in the wall width direction Z and one in the height direction Y.

Next, the sound insulation performance of ceramic wool will be described.
As described above, the ceramic wool has a refractory material, but the present inventors have found that the ceramic wool also has a performance as a sound insulating material as described below.

FIG. 3 is a test performed to compare the sound insulation performance of a wall structure in which ceramic wool is arranged between a pair of finishing materials (see FIG. 4) and a wall structure in which ceramic wool is not arranged (see FIG. 5). It is a graph which shows the result of. As shown in FIG. 4, the wall structure 1X in which the ceramic wool 9 is arranged between the pair of finishing materials 31 and 32 has the ceramic wool 9 between the studs 6 of the steel base material 4 adopting the double stud method. It is a form that is completely inserted. As shown in FIG. 5, the wall structure 1Y in which the ceramic wool is not arranged is a form in which the ceramic wool is not arranged between the studs 6 of the steel base material 4 adopting the double stud method.
The horizontal axis of FIG. 3 is the 1/1 octave band center frequency (Hz), and the vertical axis is the sound transmission loss (dB). In the test, a sound source having a predetermined frequency was placed on one side of the wall structure, and the sound transmission loss when sound was received on the other side of the wall structure was measured. The test was carried out by the measuring method specified in JIS A 1416 (Measuring method of air noise blocking performance of building members in the laboratory).

As shown in FIG. 3, it was confirmed that the sound insulation performance was improved by arranging the ceramic wool. That is, it was found that ceramic wool has a function not only as a refractory material but also as a sound insulating material. Therefore, in the wall structure 1X in which the ceramic wool 9 is arranged between the first and second finishing materials 31 and 32 as described above, not only fire resistance but also sound insulation can be obtained.

Next, the filling rate of the ceramic wool 9 and the effect of limiting the filling rate will be described.
The ratio of the area where the ceramic wool 9 is arranged to the area of the wall structure 1 on the surface including the wall width direction Z and the height direction Y is defined as the filling rate. Generally, in a wall structure, the sound insulation performance improves as the filling rate of the sound insulation material increases. On the other hand, in the wall structure, if the refractory filling rate is too high, hot air is trapped between the finishing material and the refractory material, and the temperature of the finishing material rises, so that the fire resistance is lowered. Therefore, for refractory materials, it is not always necessary that the filling rate is high.
In consideration of the above points, the wall structure 1 of the present embodiment is configured such that the filling rate of the ceramic wool 9 is 0.47, which is smaller than 0.5 (50%).

FIG. 6 is a graph showing the results of experiments carried out to verify the fire resistance performance of a wall structure having ceramic wool (see Japanese Patent No. 5015362, specifications [0052] to [0056], and FIGS. 16 to 26). Is. In the experiment, the wall-structured test piece was placed in a medium-sized composite furnace and heated for 120 minutes according to the ISO834 standard heating curve, and the temperature of each part of the test piece was measured by a thermocouple. The horizontal axis of the graph of FIG. 6 is the filling rate of ceramic wool, and the vertical axis is the maximum temperature of each part of the test piece up to 120 minutes. Here, 750 ° C. is a temperature guideline for damaging the wall structure. From the graph, it can be seen that when the filling rate of the ceramic wool is 0.5 or more, the maximum temperature among the temperatures of various parts of the test piece reaches 750 ° C., which is a temperature guideline for damaging the wall structure. That is, from the viewpoint of fire resistance, the filling rate of ceramic wool is preferably less than 0.5. Further, according to the findings of the present inventors, from the viewpoint of sound insulation performance, the filling rate of the ceramic wool is preferably in the range of more than 0 and less than 0.7, more than 0.1 and 0. A range smaller than .5 is more preferable.
Based on the above examination results, the wall structure 1 of the present embodiment secures sufficient sound absorption performance while suppressing damage to the wall structure 1 by setting the filling rate of the ceramic wool 9 to 0.48. ing.

According to the first embodiment of the present invention as described above, the sound absorbing performance of the wall structure 1 is improved by arranging the ceramic wool 9 between the first and second finishing materials 31 and 32. At the same time, the fire resistance performance can be improved. Further, since the ceramic wool 9 is supported by the steady rest 7, it is not necessary to separately prepare a fixing member when fixing the ceramic wool 9, and the ceramic wool 9 can be arranged at a lower cost. Further, by using the common stud method for the steel base material 4, the finishing materials 31 and 32 can be divided into a plurality of spaces V. For example, by placing the steel base material 4 on the steady rest 7, each space V can be divided. The ceramic wool 9 can be made independent.

The method of arranging the ceramic wool 9 is not limited to the above, and can be appropriately changed depending on workability and cost. For example, as shown in FIG. 7, the blocks of the ceramic wool 9 are arranged in the space V adjacent to each other in the height direction Y, and are arranged so as to form a vertical stripe pattern in which every other block is arranged in the wall thickness direction X. May be good. Further, in another example (not shown), even if the blocks of the ceramic wool 9 are arranged in the space V adjacent to each other in the wall width direction Z and arranged in a horizontal stripe pattern in which every other block is arranged in the height direction Y. Good. Further, it is not always necessary to fill the entire individual space V with the ceramic wool 9, and for example, a block of the ceramic wool 9 formed to be about half the size of the space V may be arranged in each space V.
Further, the filling rate does not necessarily have to be smaller than 0.5. Further, the ceramic wool 9 may be spread inside the stud 6.
