- the sound absorbing material can be appropriately inserted or filled in the hollow region ⁇ , which is extremely advantageous in improving the sound insulation of the wall structure.
- the partition wall structure of the double runner / parallel column construction method can reliably block the propagation path of solid-borne sound, thus preventing the sound insulation loss and designing the wall structure that exhibits good sound insulation performance. It is considered possible.
- the wall thickness ⁇ 2 is doubled compared to the partition wall structure (FIG. 20A) of the single runner / common stud column method, so that the available room area or room space can be effectively used. There arises an architectural design or construction economic problem of a relatively large reduction or reduction.
- Fig. 21 (B) shows the partition wall structure of the single runner / staggered column method.
- the studs 4 are arranged in a staggered arrangement alternately eccentric to one side with respect to the wall core XX due to the arrangement of the spacers 9.

- Patent Documents 2 to 4 Japanese Patent No. 497176, Japanese Patent No. 5663119, and Japanese Patent No. 5296600.
- the partition wall structure of the single runner / staggered column method As with the partition wall structure (FIG. 20 (B)) of the single runner / saddle plate staggered array method, the propagation path of the solid propagation sound is not formed. If compared with the partition wall structure (FIG. 21A) of the double runner / parallel column construction method, the sound insulation performance is slightly inferior, but a sound insulation wall that exhibits relatively good sound insulation performance can be designed. In addition, the single runner / staggered column method does not require special considerations or considerations in terms of structure, detailed design, or construction due to the insertion of the siding plate 4a (FIG. 20B).
- the studs 4 are merely arranged in a staggered manner, it is only necessary to slightly increase the wall thickness ⁇ 2 as compared with the partition wall structure (FIG. 20 (A)) of the single runner / common stud method, so that it can be effectively used.
- the living room area or living room space is only slightly reduced or reduced as compared to the partition wall structure of the single runner / common column method.
- the thickness ⁇ 2 about 200 mm

- a C-shaped steel stud having a width ⁇ 3 having substantially the same or equivalent width as the runner 2 is erected on the end portion 100a as a steel stud 7.
- This type of steel stud 7 is generally called by a name such as a vertical runner, an end runner, or an end stud, and hereinafter, this building element is called an “end pole”.
- the applicant has developed a high-performance sound insulation wall (model A-2000 / WI) that has a partition structure (Fig. 21 (B)) with a single-runner / staggered column construction method and has already been put into practical use. ing.
- This high-performance sound insulation wall (model A-2000 / WI) is preferably constructed as a boundary wall for apartment buildings and hotels that require high sound insulation performance, especially as a boundary wall for high-rise or super-high-rise apartment buildings or hotels, Due to its high sound insulation performance, it has a very significant advantage in combination with the effects of reducing the structural load due to the light weight of the partition walls and shortening the construction period.
- the TLD value (D-Number of Sound Transmission Loss, TL D ) is the sound insulation effect or sound insulation of the partition wall, as measured by the sound transmission loss measured according to the measurement method specified in JIS A 1416 (ISO140-3). It is a numerical value shown as performance, and more specifically, is an index of the sound insulation effect or sound insulation performance of the partition wall and the like obtained by evaluating the measurement result based on the sound insulation reference curve defined by the Architectural Institute of Japan.
- the partition wall structure of the double runner / parallel partition method exhibits excellent sound insulation performance, but if this partition wall structure is used, there is a problem that the wall thickness increases considerably.
- the partition wall structure of the single runner / staggered column method or the single runner / staggered staggered array method the wall thickness is only slightly increased, and the problem of increased wall thickness can be substantially avoided.
- the partition structure of the single runner / staggered column method or the single runner / plaid staggered array method is slightly inferior to the double runner / parallel column method partition wall structure in terms of sound insulation performance. There was room left to do.
- the present inventors have increased the thickness and density of the heat insulating / sound absorbing material (glass wool, etc.) of the hollow part in the partition wall structure of the single runner / staggered column method, or a damping adhesive that exhibits damping performance, etc.
- a number of sound-insulating walls with improved measures or countermeasures such as the use of adhesive as a face material were prototyped and tested for sound-insulating performance under various conditions.
- In the frequency range of mid to high frequencies (500 to 2000 Hz) It is difficult to effectively increase the transmission loss. Therefore, such an improvement measure or countermeasure cannot improve the sound insulation performance as desired.
- this sound insulation performance test there is no significant sound insulation defect at a specific frequency. For this reason, it has been considered that it is practically extremely difficult to further improve the sound insulation performance.
- the present invention has been made in view of such circumstances, and the object of the present invention is to provide a medium-high frequency range in a partition wall structure of a single runner / staggered column method or a single runner / staggered plate staggered array method.
- the purpose is to increase sound transmission loss with respect to noise and improve the sound insulation performance of the partition wall.
- the present inventors have increased the thickness of the heat insulating / absorbing material such as glass wool inserted into the hollow portion of the wall.
- a plurality of partition walls having different thicknesses or densities, a partition wall using a special adhesive such as a vibration-damping adhesive as an adhesive for bonding the lower surface material and the upper surface material, or the structure of the wall end A number of test specimens such as partition walls with different values were manufactured, and a number of sound insulation performance tests with different conditions were performed.
