Description

The present invention relates to a partition wall and a method for producing the partition wall.

The upper runner supported by the ceiling frame (ceiling slab) of the building, the lower runner supported by the floor frame (floor slab) of the building, and the horizontal direction supported between the upper runner and the lower runner. A partition wall having a plurality of studs arranged at intervals and a wall surface member supported in a state of straddling the plurality of studs has been conventionally known.

There are various types of partition walls that support the wall surface members on the studs, and specific examples thereof include a single-sided two-sheet type and a double-sided two-sheet type. Of these, the single-sided two-ply type has a wall surface member fixed to one side of the stud, and the wall surface member has an underlayment fixed to the stud and an upholstery fixed to the underlayment. On the other hand, in the double-sided double-sided type, wall surface members are fixed on both sides of the stud, and each wall surface member has an underlayment and an upper upholstery.

In a wall surface member having such an upholstery and an underlayment, each of the upholstery and the underlayment is usually formed of a plurality of face materials arranged so as to form a wall shape.

Fire resistance may be required for the partition wall, and in this case, a nonflammable face material such as gypsum board or calcium silicate board may be used as the face material constituting the wall surface member. In the conventional partition wall of the single-sided double-layered type and the double-sided double-layered type using such a gypsum board or the like, the face material constituting the underlayment is usually fixed to the stud by screws (screws) or the like, and the upholstery is used. The face material constituting the above is fastened to the face material constituting the underlayment with an adhesive, and is fixed with staples, screws, or the like.

By the way, it has been conventionally known that an abnormal noise called a scraping noise can be generated in such a partition wall. The scraping noise is thought to be caused by the inter-story displacement of the building, but the underlying mechanism of its occurrence has not yet been clearly elucidated.

Various techniques for suppressing scratching noise have been proposed so far. For example, in Patent Document 1 and Patent Document 2, in order to prevent the upper runner from coming into contact with the face material, for example, A partition wall that forms a relief in a portion of the face material facing the upper runner, a partition wall that provides a spacer between the face material and the stud, and the like are disclosed. These techniques were devised based on the knowledge that the cause of the scratching noise is the frictional contact between the runner and the face material.

Japanese Patent No. 4918333 Japanese Patent No. 3907424

However, in the above-mentioned prior art, since relief is formed in the face material, it takes time and effort to process the face material, and the processing cost increases. Further, when a spacer is provided between the face material and the stud, it takes time and effort to attach the spacer.

On the other hand, the wall surface member is fixed to the stud by a fixing member such as a screw, and at this time, the fixing members are inserted at intervals in the vertical direction. Here, the fixing member is generally inserted at a position as close as possible to the upper runner and the lower runner on the upper runner side and the lower runner side, specifically, at a position about 10 mm away from the upper runner or the lower runner. ing. Further, the other fixing members are inserted so as to have a gap of about 150 to 300 mm with respect to the adjacent fixing member. Further, in the vicinity of the joint on the wall surface member, the fixing member is inserted at a position about 10 to 100 mm away from the joint. The inventor of the present invention considers that the insertion position of such a fixing member is also one of the causes of the scratching noise, and considers that the scraping noise can be suppressed easily and cost extremely by devising the insertion position. I did a lot of research.

The present invention has been made in consideration of the above circumstances, and an object of the present invention is to provide a partition wall capable of suppressing scraping noise while easily and extremely suppressing costs.

The partition wall according to the present invention has a longitudinal upper runner supported by the ceiling skeleton of the building and a longitudinal lower runner supported by the floor skeleton of the building and arranged below the upper runner. And, it is supported between the upper runner and the lower runner, and is supported by a plurality of studs which are vertically spaced apart from each other in the horizontal direction and straddle the plurality of studs. A wall member located on both sides or one side of the stud is provided, and the upper runner and the lower runner have a pair of side plate portions extending in the vertical direction and a pair of side plate portions extending in the vertical direction in a cross-sectional view in a direction orthogonal to the longitudinal direction. It is a U-shape having a base plate portion that connects a pair of side plate portions, and the pair of side plate portions and the base plate portion in the upper runner form a groove open downward, and the lower runner has a groove. The pair of side plate portions and the base plate portion form a groove open upward, and the stud is inserted into the inside of the groove of the upper runner and the inside of the groove of the lower runner, and the pair It is fixed in contact with one inner surface of one of the side plate portions or both inner surfaces, and the wall surface member is arranged so as to face both the outer surface of the side plate portion and the stud, and penetrates the wall surface member.

It is provided at a position away from the base plate portion of the side runner.

According to the present inventor, when the fixing member is located relatively close to the upper runner or the lower runner, the wall surface member and the upper runner or the lower runner are in close contact with each other, so that the scraping noise becomes louder. It was found that the scraping noise is suppressed when the fixing member is separated from the upper runner or the lower runner to some extent. As a result of trial and error, when the distance from the base plate portion of the upper runner or the lower runner to the tip of the side plate portion is h, the fixing member closest to the upper runner is on the upper side by 2.5 h or more and 7.5 h or less. It is provided at a position away from the base plate of the runner, and / or the fixing member closest to the lower runner is provided at a position away from the base plate of the lower runner by 2.5 h or more and 7.5 h or less. In this case, the wall surface member and the upper runner or the lower runner are not pressed against each other excessively strongly, so that the fixing member does not excessively separate from the end portion of the wall surface member while effectively suppressing the scraping noise. As a result, they have found that the wall surface member can be stably fixed to the stud, and have reached the present invention.
According to the partition wall according to the present invention, since the scraping noise is suppressed by devising the position of the fixing member, the scraping noise can be suppressed easily and while extremely suppressing the cost.

The fixing member 33 is inserted from the surface side of the upholstery surface member 32 toward the underlayment surface member 22. The fixing member 33 is set to a length that does not penetrate the underlaying surface material 22.

Next, an example of a method for manufacturing the partition wall 1 according to the present embodiment will be described.

First, a base is formed by providing the upper runner 4, the lower runner 5, and the stud 6 (lower terrain process).

Next, the wall surface member 10 is supported in a state of straddling the plurality of studs 6 (wall surface forming step). In the wall surface forming step, first, the underlayment 21 is formed by supporting the plurality of studs 6 by arranging and supporting a plurality of underlaying surface members 22 with the back surfaces facing the sides of the studs 6 so as to form a wall shape. To do.

At this time, in the present embodiment, as described above, the underlaying surface material 22 is penetrated from the surface of the fixing member 23 such as a tapping screw or a screw in a so-called horizontal tension state, and the fixing member 23 becomes a stud 6. It is fixed by being inserted. The adjacent underlaying surface members 22 are arranged in a so-called abutting state, and the end faces of the adjacent underlaying surface members 22 are in a state of being abutted against each other.

Then, as described above, when the distance from the base plate portion 4B of the upper runner 4 to the tip of the side plate portion 4S is h, the fixing member 23 closest to the upper runner 4 is only 2.5 h or more and 7.5 h or less. It is provided at a position away from the base plate portion 4B of the upper runner 4. Further, the fixing member 23 closest to the lower runner 5 is also provided under the same conditions as the fixing member 23 closest to the upper runner 4.

Next, on the underlaying surface material 22 on which the underlaying surface 21 is formed as described above, a plurality of upholstery surface materials 32 with the back surface facing the front surface side of the underlaying surface material 22 are arranged so as to form a wall shape. , By supporting the corresponding underlaying surface material 22, the overlining 31 is formed. As a result, the wall surface member 10 is formed. The upholstery 31 may be formed of abutment or a watermark.

In the partition wall 1 according to the present embodiment described above, the scraping noise can be suppressed by devising the position of the fixing member 23, so that the scraping noise can be suppressed easily and cost extremely.

That is, in the present embodiment, when the distance from the base plate portion 4B of the upper runner 4 to the tip of the side plate portion 4S is h, the fixing member 23 closest to the upper runner 4 is 2.5 h or more and 7.5 h or less. It is provided at a position away from the base plate portion 4B of the upper runner 4. Further, the fixing member 23 closest to the lower runner 5 is also provided under the same conditions as the fixing member 23 closest to the upper runner 4. In this case, the wall surface member 10 (underlaying surface material 22) and the upper runner 4 or the lower runner 5 are not pressed against each other excessively strongly, so that the wall surface member 10 (underlaying) effectively suppresses the scraping noise. Since the fixing member 23 is not excessively separated from the end portion of the face member 22), the wall surface member 10 (underlay face member 22) can be stably fixed to the stud 6. Since the scraping noise is suppressed by devising the position of the fixing member 23 in this way, the scraping noise can be suppressed easily and while extremely suppressing the cost.

If the thickness of the side plate portion of the upper runner 4 or the lower runner 5 is excessively large, the underlaying surface material 22 and the upper runner 4 or the lower runner 5 are pressed excessively strongly against each other when the fixing member 23 is provided. Therefore, there is a risk that scratching noise is likely to occur. From such a viewpoint, the thickness of the side plate portions of the upper runner 4 and the lower runner 5 is preferably small, specifically 0.4 mm or more and 2.3 mm or less.

(Example)
Next, the scratch suppression performance of Examples 1 and 2 in which the partition wall 1 according to the present embodiment is specifically produced will be described in comparison with the partition wall according to the comparative example.

First, as the partition wall 1 according to the first embodiment, a gypsum board having a thickness of 21 mm is used as the underlaying surface material 22, and a gypsum board having a thickness of 9.5 mm is used as the upholstery surface material 32.

Further, the distance from the base plate portion of the lower runner 5 to the tip of the side plate portion is also 40 mm, and the fixing member 23 closest to the lower runner 5 is located at a position 150 mm away from the base plate portion of the lower runner 5. Provided. That is, the distance L = 3.75h.
Further, the other fixing member 23 between the fixing member 23 closest to the upper runner 4 and the fixing member 23 closest to the lower runner 5 is (1) about 10 mm from the joint when it is close to the joint. It is said that the positions are separated (specifically, within a range of 10 mm or more and 20 mm or less), and (2) a distance of about 200 mm (specifically, within a range of 150 mm or more and 300 mm or less) is provided with respect to the adjacent fixing member 23. It is provided so as to satisfy general conditions.

In the second embodiment, the fixing member 23 closest to the upper runner 4 is provided at a position 130 mm away from the base plate portion 4B of the upper runner 4. Further, the fixing member 23 closest to the lower runner 5 is provided at a position 130 mm away from the base plate portion of the lower runner 5. That is, the distance L = 3.25 h. Other conditions are the same as in Example 1.

On the other hand, in the partition wall according to the comparative example, as shown in FIG. 5, the fixing member 23 closest to the upper runner 4 is provided at a position 50 mm away from the base plate portion 4B of the upper runner 4. That is, the distance L = 1.25h. Further, the fixing member 23 closest to the lower runner 5 is provided at a position 50 mm away from the base plate portion of the lower runner 5. Other conditions are the same as in Example 1.

FIG. 6 shows the test equipment used in the scratching sound confirmation test for confirming the scratching sound suppressing performance of Examples 1 to 5. In the test facility, the lower runner 5 was installed on the floor surface, and both ends of the lower runner 5 were fixed to the floor surface by the runner restraint 100 to keep the partition wall in an upright state. Further, a hydraulic jack 101 is provided which comes into contact with one end of the upper runner 4 and applies a force in the horizontal direction to the upper runner 4. Then, in the scraping sound confirmation test, a force was applied to the upper runner 4 by the hydraulic jack 101 to form a behavior imitating the interlayer displacement. Then, the sound generated at this time is detected by a microphone provided at a position 500 mm away from the partition wall in the out-of-plane direction, the noise level is verified, and whether or not a scraping sound is generated is sensory. evaluated.

In the verification of the noise level, the maximum value Lmax of the noise level (Hz) at each frequency of 125 Hz, 250 Hz, 500 Hz, 1000 Hz, 2000 Hz, and 4000 Hz, which occurred in Examples 1 to 5 and Comparative Example, was extracted and compared with each other. I went by doing. Furthermore, the AP values in Examples 1 to 5 and Comparative Examples were also measured. The AP value is a value indicating the overall noise level, not the noise level for each frequency.

FIG. 3 is a table showing the results of a scratching sound confirmation test on the partition wall according to Examples 1 to 5 and the partition wall according to Comparative Example, and FIG. 4 shows the partition wall and the partition wall according to Examples 1 to 5. It is the figure which showed the result of the scraping sound confirmation test with respect to the partition wall concerning the comparative example in a graph. In FIGS. 3 and 4, the maximum value of the noise level when the scraping sound confirmation test is performed on Examples 1 to 5 and Comparative Example is shown for each of the frequencies described above. Further, the noise level of the hydraulic jack 101 when only the hydraulic jack 101 is moved is also shown as a reference.

As shown in FIGS. 3 and 4, in Examples 1 to 5 (L = 2.5h to 7.5h), the noise levels at all frequencies of 125Hz, 250Hz, 500Hz, 1000Hz, 2000Hz and 4000Hz are comparative examples. The difference from the noise level when only the hydraulic jack 101 is driven is extremely small. In particular, for Examples 1, 2, 4, and 5 (L = 3.25 h, L = 3.75 h, L = 5.0, L = 7.5), the noise level and AP value at each frequency are both. It was significantly smaller than the comparative example. Further, in Examples 1, 2, 4, and 5, the scraping sound could not be confirmed sensually. On the other hand, in Example 3 (L = 2.5h), it was confirmed that a small amount of scraping sound was generated, but it was sufficiently small as compared with the scraping sound generated in Comparative Example.

From the results of the scratching sound confirmation test for the above examples, the scratching sound suppressing effect of the partition wall according to the present invention could be confirmed. On the other hand, in the fifth embodiment, the fixing member 23 closest to the upper runner 4 is provided at a position 300 mm away from the base plate portion 4B of the upper runner 4, but in visual observation, it is observed that the hydraulic jack 101 operates. It was found that a slight gap was formed between the stud 6 and the underlaying surface material 22. Therefore, it was presumed that if the position of the fixing member 23 closest to the upper runner 4 is made significantly larger than 300 mm from the base plate portion 4B of the upper runner 4, the fixed state may become unstable. Specifically, if the fixing member 23 closest to the upper runner 4 is made significantly larger than the position 300 mm from the base plate portion 4B, the tightening between the underlaying surface material 22 and the stud 6 is likely to be loosened, and in the event of an earthquake or the like. It was presumed that the partition wall would be easier to move in the out-of-plane direction. In such a case, cracks are likely to occur, and abnormal noise due to the movement of the partition wall in the out-of-plane direction is also likely to occur. For this reason, the present inventor defines the upper limit of the preferable installation range of the upper runner 4 or the lower runner as the distance from the base plate portion of the upper runner 4 or the lower runner 5 to 7.5 h or less. .. On the other hand, as is clear from the graph as shown in FIG. 4, in Examples 1 and 2, the noise level is remarkably suppressed as compared with Comparative Example. Therefore, it can be evaluated that the noise level is remarkably suppressed and the fixed state is also good at around L = 3.0h or more and 4.0h. Further, the noise level of Example 2 (L = 3.25h) is significantly lower than the noise level of Example 3 (L = 2.5h). From this result, it is inferred that the range of L = 3.25h or more and 4.0h is an extremely good range.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications may be made in the above-described embodiments. For example, the partition wall 1 according to the above-described embodiment is a double-sided double-sided type, but the partition wall 1 may be a single-sided double-sided type.

Further, in the above-described embodiment, the upper runner 4, the lower runner 5 and the stud 6 are made of hot-dip galvanized steel sheet, but the materials thereof are not particularly limited.
