Description

The present invention relates to a partition wall and a method of making the same.

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 and lower runners. 2. Description of the Related Art Conventionally, a partition wall has been known which has a plurality of studs arranged at intervals and a wall member supported in a state of straddling the plurality of studs.

There are various types of partition walls that support wall members on studs, and specific examples include a single-sided two-ply type and a double-sided two-ply type. Among these, in the single-sided double-layer type, a wall member is fixed to one side of the stud, and the wall member has a bottom panel fixed to the stud and a top panel fixed to the bottom panel. On the other hand, in the double-sided two-ply type, wall members are fixed on both sides of the stud, and each wall member has an underlay and an overlay.

In a wall member having such an upper panel and a lower panel, each of the upper panel and the lower panel is usually formed of a plurality of surface members arranged to form a wall.

In some cases, partition walls are required to have fire resistance, and in this case, non-combustible facing materials such as gypsum boards and calcium silicate boards are sometimes used as facing materials constituting wall members. In the conventional partition walls of the one-sided two-ply type and the double-sided two-ply type using such gypsum boards, the face material constituting the underlay is usually fixed to the studs by screws or the like, and the upholstery is fastened with an adhesive to the face material forming the underlay, and is fixed with staples, screws, or the like.

By the way, it is conventionally known that such a partition wall may generate an abnormal noise called a scraping noise. Scraping sounds are thought to be caused by the displacement between layers of buildings, but the fundamental mechanism of their generation has not yet been clearly elucidated.

Various techniques have been proposed so far as techniques for suppressing the rubbing sound. A partition wall that forms a relief in a portion of the face member facing the upper runner, a partition wall that provides a spacer between the face member and the stud, and the like are disclosed. These techniques were invented based on the finding that frictional contact between the runner and the face material is the cause of frictional noise.

Japanese Patent No. 4918333 Japanese Patent No. 3907424

However, in the above-described conventional technology, since the relief is formed in the face material, it takes time and effort to process the face material, and the processing cost increases. Moreover, when a spacer is provided between the face member and the stud, it takes time and effort to attach the spacer.

On the other hand, the wall member is fixed to the stud with a fixing member such as a screw. At this time, the fixing member is inserted with a gap 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. Other fixing members are inserted so that there is 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 generation of rubbing noise. I did intensive research.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a partition wall that can suppress rubbing noise easily and at a very low cost.

The partition wall according to the present invention includes a longitudinal upper runner supported by the ceiling frame of the building and a longitudinal lower runner supported by the floor frame of the building and arranged below the upper runner. and a plurality of vertically elongated studs supported between the upper runner and the lower runner and arranged at intervals in the horizontal direction, and supported in a state spanning the plurality of studs, Wall members located on both sides or one side of the stud, and the upper runner and the lower runner each include a pair of side plate portions extending in the vertical direction in a cross-sectional view in a direction orthogonal to the longitudinal direction, and the and a base plate portion connecting a pair of side plate portions, the pair of side plate portions and the base plate portion of the upper runner form a downwardly open groove, The pair of side plate portions and the base plate portion form grooves that are open upward, and the studs are inserted into the grooves of the upper runner and the grooves of the lower runner. It is fixed in contact with one inner surface or both inner surfaces of the side plate portions, and the wall member is arranged in a state facing both the outer surface of the side plate portion and the stud, and penetrates the wall member. and fixed to the stud by a plurality of fixing members extending to the stud, and when the distance from the base plate portion to the tip of the side plate portion is h, the fixing member closest to the upper runner is 2.5 h.

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

The inventor of the present invention found that when the fixing member is positioned relatively close to the upper runner or the lower runner, the frictional noise increases due to the close contact between the wall surface member and the upper runner or the lower runner. It has been found that when the fixing member is separated from the upper runner or the lower runner to some extent, the rubbing noise is suppressed. As a result of trial and error, when h is the distance from the base plate portion of the upper runner or the lower runner to the tip of the side plate portion, the fixing member closest to the upper runner is located above the upper runner by 2.5 h or more and 7.5 h or less. It is provided at a position away from the base plate portion of the runner and/or the fixing member closest to the lower runner is provided at a position separated from the base plate portion of the lower runner by 2.5 h or more and 7.5 h or less. When the wall surface member and the upper runner or the lower runner are pressed excessively strongly against each other, the fixing member does not excessively separate from the edge of the wall surface member while effectively suppressing the scraping sound. As a result, the inventors have found that the wall member can be stably fixed to the stud, and have completed the present invention.
According to such a partition wall according to the present invention, since the frictional noise is suppressed by devising the position of the fixing member, it is possible to suppress the frictional noise easily and at an extremely low cost.

Moreover, the fixing member 23 closest to the lower runner 5 was provided at a position separated from the base plate portion of the lower runner 5 by 300 mm. That is, the distance L=7.5h. 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 was provided at a position separated from the base plate portion 4B of the upper runner 4 by 50 mm. That is, the distance L=1.25h. Moreover, the fixing member 23 closest to the lower runner 5 was 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 rubbing sound confirmation test for confirming the rubbing noise suppression performance of Examples 1 to 5. As shown in FIG. In the test facility, the lower runners 5 were installed on the floor, and both ends of the lower runners 5 were fixed to the floor by runner restraints 100 to hold the partition wall in an upright state. Also, a hydraulic jack 101 is provided for contacting one end of the upper runner 4 and applying a force in the horizontal direction to the upper runner 4 . In the rubbing sound confirmation test, a force was applied to the upper runner 4 by the hydraulic jack 101 to form a behavior simulating inter-layer displacement. Then, the sound generated at this time was detected by a microphone provided at a position 500 mm away from the partition wall in the out-of-plane direction, and the noise level was verified. evaluated.

The noise level verification is performed by extracting 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 generated in Examples 1 to 5 and the comparative example, and comparing them with each other. I went by doing Furthermore, AP values in Examples 1 to 5 and Comparative Example were also measured. The AP value is a value that indicates the overall noise level, not the noise level for each frequency.

FIG. 3 is a table showing the results of the rubbing sound confirmation test for the partition walls according to Examples 1 to 5 and the partition walls according to the comparative example, and FIG. It is the figure which showed with the graph the result of the rubbing sound confirmation test with respect to the partition wall concerning a comparative example. FIGS. 3 and 4 show the maximum values of the noise level for each of the above-mentioned frequencies when the rubbing sound confirmation test was performed for Examples 1 to 5 and Comparative Example. Also shown for reference is the noise level of the hydraulic jack 101 when only the hydraulic jack 101 is moved.

As shown in FIGS. 3 and 4, in Examples 1 to 5 (L = 2.5 h to 7.5 h), the noise levels at all frequencies of 125 Hz, 250 Hz, 500 Hz, 1000 Hz, 2000 Hz, and 4000 Hz are lower than those of the comparative example. , and 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 = 3.25h, L = 3.75h, L = 5.0, L = 7.5), both the noise level and AP value at each frequency are It was significantly smaller than the comparative example. Moreover, in Examples 1, 2, 4, and 5, the rubbing sound could not be sensuously confirmed. On the other hand, in Example 3 (L=2.5 hours), it was confirmed that a little rubbing sound was generated, but it was sufficiently small compared to the rubbing sound generated in the comparative example.

From the results of the rubbing sound verification test for the above examples, the effect of suppressing the rubbing sound of the partition wall according to the present invention could be confirmed. On the other hand, in Example 5, 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. It was observed that a slight gap was formed between the stud 6 and the underlying panel 22 . Therefore, 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, it is presumed that the fixing 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 underlay surface material 22 and the stud 6 is likely to be loosened, resulting in an earthquake or the like. It was presumed that the partition wall became easier to move in the out-of-plane direction. In such a case, cracks are likely to occur, and noise due to movement of the partition wall in the out-of-plane direction is also likely to occur. For this reason, the inventors of the present invention set the upper limit of the preferable installation range of the upper runner 4 or the lower runner to be a distance of 7.5 h or less from the base plate portion of the upper runner 4 or the lower runner 5. . On the other hand, as is clear from the graph shown in FIG. 4, in Examples 1 and 2, the noise level is significantly suppressed as compared with the comparative example. Therefore, it can be evaluated that the noise level is remarkably suppressed and the fixing state is good when L=3.0 h or more and about 4.0 h. 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 estimated that L=3.25 h or more and around 4.0 h is a very good range.

For example, although the partition wall 1 according to the above-described embodiment is a double-sided double-sided type, the partition wall 1 may be a single-sided double-sided type.

Moreover, although the upper runner 4, the lower runner 5 and the stud 6 are made of hot-dip galvanized steel in the above-described embodiment, these materials are not particularly limited.
