Title: Floor joist constitution and sound proofing double floor with floor joist constitution
Inventor: NAKAMURA KOSUKE
IPC: E04F15/00
Filed: 1995-09-25
Abstract: PROBLEM TO BE SOLVED: To provide floor joist constitution high in sound proofing performance even in a low sound area by sticking elastic sheet material to sound proofing double floor joists disposed on a floor bed so as to support floor base material. SOLUTION: Floor joists 3 are supported on a floor bed 1 through support legs 5, and floor base material 2 is provided on the floor joists 3 to constitute a sound proofing double floor. In this case, elastic sheet material 4 is stuck to the floor joist 3. In such a sound proofing double floor, impact applied to the floor base material 2 is relaxed by the elastic sheet material 4 so as to reduce the solid propagation of vibrational energy from the support legs 5 to the floor bed 1. Since a solid propagation path is interrupted, impact noise is not easily transmitted to the lower floor. Impact noise in a low sound area can thereby be damped effectively.

CONSTITUTION:An X-ray diffraction method is used in order to detect the hydrogen erosion to be generated in the pressure vessel, piping material, etc. which are exposed for a long period of time to the high-temp. high-pressure hydrogen environment. The X-ray diffraction wave thereof is then measured. The X-ray is converted by a monochrometer to a monochromatic ray at this time and the half value width of the diffraction wave of the Kbeta ray at the higher order than the 200 face of the member is measured without using an X-ray filter. The half value width of the X-ray diffraction wave of the member changes prior to a decrease of a Charpy absorption energy curve and, therefore, the non-destructive detection of the hydrogen erosion arising in the member is permitted by measuring said half value width.
