Problems solved by technology

However, in this method, the wall acts as the final source of heavy floor impact noise, and its rigidity reinforcement effect on the planar member is small, so the effect of reducing floor impact noise is limited.

Abstract

The invention provides a wall structure capable of inexpensively enhancing the impact reducing effect as a heavy floor impulsive sound reducing countermeasure of a house made of thin and lightweight shape steel. In this wall structure 100, the wall structure 100 is formed by sticking plaster boards 20 and 21 to a plurality of vertical frames 10. A connecting member 30 is arranged between the vertical frames 10 to a large amplitude part (a belly part) when the wall structure 100 vibrates, and plane members 20 and 21 are fixed to the vertical frames 10 and the connecting member 30.

Description

Technical field [0001] The present invention relates to a wall structure, especially a structure with excellent sound insulation performance. Background technique [0002] In recent years, in buildings such as two-story buildings, the impact sound generated on the lower floors due to walking, jumping on the upper floors, falling objects, etc. has often become a problem. This impact sound is called floor impact sound, and the measurement method and evaluation method are prescribed by JIS standards. [0003] Specifically, the floor impact sound includes (1) a heavy floor impact sound caused by a child's jumping and other heavy objects falling, and (2) a lightweight floor impact sound caused by a light weight object such as a spoon falling. [0004] Generally, the former (1) is the main component of low-frequency sound such as the 63 Hz band (1 / 1 octave band), and the latter (2) is the mid-range to the high-frequency band of the 250 Hz band and the 500 Hz band (1 / 1 octave band). The...
