Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a partition wall structure, and more particularly to a partition wall structure of a dry construction method for preventing generation of scratching noise.
[0002]
[Prior art]
As a partition wall for a dry construction method in a building or a work, a lightweight steel partition wall with a frame structure in which a building surface material (board material) such as gypsum board or calcium silicate board is attached to a stud stud made of steel is widely used. It is offered to. In the partition wall having such a structure, the steel studs are aligned and arranged at predetermined intervals along the wall core, and the upper end portion and the lower end portion of the steel stud are fixed to the upper runner and the floor runner, respectively. The board material forming the wall surface is attached to the runner and steel stud frame structure by screws, staples, adhesives, or the like.
[0003]
In recent years, attention has been paid to the problem of noise generation on partition walls, particularly in medium- and high-rise buildings. This kind of abnormal noise is generally called a rubbing sound, and various measures for solving the problem of rubbing noise have been proposed. However, no fundamental solution to eliminate the generation of scratching noise has been proposed yet.
[0004]
The rubbing noise is believed to be mainly due to building behavior or interlayer displacement. For example, when a building vibrates in a long period during strong winds and an interlayer displacement occurs between floors, an unintended forcing force or external force acts on the partition wall, and stress acts on the components of the partition wall. Due to the stress in the partition wall, each component member of the partition wall tends to be relatively displaced, and as a result, the frictional contact member generates a rubbing sound such as a squeak noise.
[0005]
This type of rubbing noise is particularly likely to occur on middle and high floors of medium and high-rise buildings. For example, in middle- and high-rise hotels, office buildings, or apartment buildings, the behavior of buildings or interlayer displacement tends to be relatively large in the middle- and high-rise parts due to the effects of wind pressure acting on the building. The frequency is relatively high. For this reason, guests on the middle and high floors are likely to feel discomfort or anxiety due to such rubbing noise.
[0006]
In order to prevent the generation of such a rubbing sound, as disclosed in Japanese Utility Model Laid-Open No. 6-14310, a low-friction slip material such as PP tape or Teflon (registered trademark) tape is contacted between the stud, the runner and the board. Or an upper structure such as an upper floor slab or a beam and the upper runner are connected via a special metal fitting for reducing scratching noise, as disclosed in Japanese Patent Publication No. 4-47742. Measures have been proposed, and these measures have already been put into practical use.
[0007]
[Problems to be solved by the invention]
However, with the above-mentioned anti-friction measure using a low-friction material such as a low-friction tape material, a relatively troublesome field work of attaching or wrapping the cushioning material to the stud is required, so the process and work are complicated. At the same time, it is difficult in practice to accurately attach a resin tape or the like to the generation source of the rubbing sound. Therefore, further improvement is required to reliably take measures against the rubbing noise. In addition, this type of cushioning material is difficult to maintain the initial performance over a long period of time due to wear and aging of the low friction material itself, and is not suitable for permanent measures against scratching.
[0008]
Also in the countermeasures against the scratching noise using the above-mentioned special metal fittings, the necessity for the installation work of the special metal fittings, the maintenance of the special metal fittings, the durability of the metal component parts, etc. are similarly problematic. At the same time, when such special metal fittings are used, the number of parts increases, material costs increase, man-hours increase, the necessity of additional special metal fitting installation process, and the partition wall construction process associated with this increase. Problems such as lengthening occur.
[0009]
The present invention has been made in view of such circumstances, and the object of the present invention is to determine the number of parts and the number of man-hours in a partition wall of a dry construction method constructed by a shaft member such as a steel stud, runner and board material. It is an object of the present invention to provide a partition wall structure that can reliably and permanently prevent the generation of scratching noise by simple construction without increasing the amount of friction.
[0010]
[Means and Actions for Solving the Problems]
In order to achieve the above-mentioned object, the present invention has a construction in which a building surface material is attached to a steel shaft member including upper and lower steel runners and steel studs, and the building surface material fixed to the stud is provided. In the partition wall structure of the dry construction method arranged so that the back surface of the upper end portion faces the side surface of the upper runner, the upper runner is provided with separation means for separating the side surface of the upper runner from the back surface of the upper end portion of the building surface material. A gap for preventing frictional contact between the side edge portion of the building surface member and the upper end portion of the building surface material is formed between the side surface of the upper runner and the back surface of the upper end portion of the building surface material by the separating means. The separating means comprises a partition wall structure comprising a receding surface of the face material formed on the back surface of the upper end portion of the building face material .
[0011]
In general, the interlaminar displacement of each layer of the building causes stress and displacement in the components of the partition wall, and in particular, the upper runner is displaced horizontally relative to the stud. When the stress is applied to the constituent members in the partition wall due to the horizontal displacement of the upper runner and the stress exceeds the friction holding force between the members, relative displacement between the members occurs. Up to now, scratching noise such as squeak noise has been recognized as noise generated when the structural members inside the partition wall are relatively displaced, but the generation source and generation mechanism have not been accurately specified. . Based on the knowledge that the main cause of scratching is the frictional contact between the upper runner and the building surface material such as gypsum board, the present inventor is in a state where the upper runner side surface and the building material board back surface are slightly separated from each other. As a result of testing the generation of scratching noise, the conclusion was reached that the scratching noise can be generally eliminated by separating the upper runner and the building material board.
[0012]
According to the above configuration of the present invention, the partition wall does not form a frictional contact portion between the upper runner and the building surface material, which is the cause of the generation of fretting noise. It is substantially eliminated by the separation of. Thus, the present invention fundamentally removes the main source of scratching noise and reliably prevents the generation of scratching noise. In addition, the anti-friction effect according to the present invention lasts semi-permanently.
Further, in the measures for preventing fretting noise by the partition wall structure, a member such as a low friction material or a special metal fitting is not used. Therefore, the partition wall can be constructed by a simple process without causing problems such as an increase in the number of parts and man-hours.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
According to a preferred embodiment of the present invention, the receding surface comprises a recess formed on the back surface of the upper end of the building surface material, or a tapered surface formed on the upper edge of the surface material. For example, the building surface material is made of gypsum board, and the receding surface is made of a tapered surface constituting a tapered edge of the gypsum board. The height dimension of the receding surface is set to be 10 to 40 mm larger than the height of the side edge portion of the upper runner. The receding dimension of the receding surface is set to a dimension of about 0.3 to 3.0 mm.
[0015]
Preferably, a fireproof material or a sound insulating material is filled between the upper end of the building surface material and the building structure that supports the upper runner. The fireproof material functions as a cushioning material that improves the fireproof performance of the partition wall and absorbs the relative displacement between the building surface material and the building structure. In addition, the sound insulating material prevents abnormal noise generated inside the partition wall from leaking into the room.

[0022]
FIG. 3 is an enlarged cross-sectional view showing the upper structure of the partition wall 10.
As for the upper end part of the lower-pasting board 2, the inner surface is slightly retracted into the board, and between the receding surface 20 of the lower-pasting board 2 and the side edge part (web part) 19 of the upper runner 12, A gap 21 is formed. The receding dimension G of the receding surface 20 is set to about 1.0 to 3.0 mm, and the dimension g of the gap 21 is set to a range of 0.3 to 1.5 mm, for example, 0.5 mm. The height dimension h of the side edge portion 19 (distance between the bottom surface of the floor slab F2 and the bottom edge of the side edge portion) is generally about 30 to 40 mm, and the height dimension H of the receding surface 20 (from the bottom surface of the floor slab F2 to the bottom of the receding surface). The distance) is set to be about 10 to 40 mm larger than this, and H is set to 40 to 80 mm. For example, when the grooved steel: C-40 × 80 × 0.8 (h × w × t) mm is used as the upper runner 12, the height dimension H is set to 60 mm.
[0023]
The screws 8 fix the lower pasting board 2 to the studs 10 below the upper runner 12, and the latches 9 are distributed at predetermined intervals, and the upper pasting board 3 is placed on the lower pasting board 2 over the entire wall surface. Secure to. The back surface 2 a of the lower sticking boat 2 is in contact with the side surface portion (web portion) 10 a of the stud 10.
[0024]
The upper end surface 22 of the lower paste board 2 is slightly spaced from the lower surface of the upper floor slab F2, and the refractory filler 40 is filled between the upper end surface 22 and the upper floor slab F2. The upper end surface 32 of the upper paste board 3 is also slightly spaced from the lower surface of the upper floor slab F2, and the sound insulating sealing material 50 is filled between the upper end surface 32 and the upper floor slab F2. The A rock wool felt for fireproof joints, for example, “Tiger Rock Felt (220 kg / m ³ )” (product of Yoshino Gypsum Co., Ltd.) is preferably used as the fireproof filler 40, and the sound insulating sealant 50 includes, for example, “ Sealing materials such as “Tiger AC Tight” (acrylic sealant), “Tiger Gyptite” (inorganic gypsum sealant) or “Tiger refractory sealant” (interlayer displacement tracking type modified silicon sealant) (all of which are Yoshino Gypsum Co., Ltd.) Product) can be suitably used.
[0025]
When an interlayer displacement occurs in the slabs F1: F2 due to the behavior of the building during a strong wind, the stud 10, the floor runner 11, the upper runner 12, and the lower paste board 2 constituting the partition wall 1 are relatively displaced. In the conventional partition wall structure, the inner side surface of the upper end portion of the lower pasting board 2 is in frictional contact with the side edge portion 19 of the upper runner 12 and rubs against each other. However, in the partition wall 1 having the above-described configuration, the inner surface of the upper end portion of the lower paste board 2 is retracted from the side edge portion 19 and a gap 21 is formed between the retracted surface 20 and the side edge portion 19. Does not occur.
[0026]
According to the inventor's experimental results, the main vibration source or generation source of the rubbing sound is the friction contact portion between the upper runner 12 and the lower board 2, and the contact between the two is prevented by the gap 21. The rubbing sound generated from the entire partition wall is greatly reduced, and the rubbing sound is substantially eliminated. Moreover, according to such a configuration, complicated work such as mounting of a low-friction material such as a resin tape or fixing of a special metal fitting is not required, and a material that can be worn or deteriorated over time is not used. In addition, it is possible to reliably and permanently prevent the generation of scratching sound. Thus, although the partition wall structure has a very simple configuration, the partition wall structure exhibits a remarkable effect in reducing fretting noise, and thus is extremely advantageous practically.
