    • PROBLEM TO BE SOLVED: To provide a fireproof and soundproof structure for a wall, which is excellent in fire resistance efficiency, is capable of preventing dew condensation on a back surface of a steel plate exterior material and preventing the generation of rust due to infiltration of rainwater from an end part of the steel plate exterior material, is excellent in sound insulation, and is light in weight.SOLUTION: In the fireproof and soundproof structure for a wall, a plurality of recessed and projected steel plate exterior materials 11 are arranged side by side with respective ends 12, 13 overlapped on the front and back, and a sheet-like inorganic fiber heat insulation material 20 is bent along recesses and projection and stuck to the back surface of the steel plate exterior material 11. The inorganic fiber heat insulation material 20 is not interposed between the overlapped ends 12, 13 of the steel plate exterior materials 11, a plaster board 15 with waterproof paper stuck to at least one surface thereof is in abutment with the back side of the inorganic fiber heat insulation material 20, and the steel plate exterior material 11, the inorganic fiber heat insulation material 20 and the plaster board 15 are fixed to a steel column or furring strip 18 by driving a fixing machine screw 19 from the side of the steel plate exterior material 11.
    • 要解决的问题:为了提供耐火效率优异的防火隔音结构,能够防止钢板外部材料的背面发生结露,并防止生锈 从钢板外部材料的端部渗入雨水,隔音性能优良,重量轻。 解决方案:在墙壁的防火隔音结构中,多个凹凸投影钢板外部材料11并排设置,其相应的端部12,13重叠在前后上,并且片状无机 纤维隔热材料20沿着凹部和突起弯曲并粘附到钢板外部材料11的后表面。无机纤维隔热材料20不夹在钢板外部材料11的重叠端12,13之间, 具有粘附在其至少一个表面上的防水纸的石膏板15与无机纤维隔热材料20的背面邻接,钢板外部材料11,无机纤维隔热材料20和石膏板15 通过从钢板外部材料11的侧面驱动固定机螺钉19而固定到钢柱或橡胶条18上。版权所有(C)2012,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a ceiling for reducing the impact noises of a floor while preventing dew condensation without excessively increasing the thickness of a ceiling portion. SOLUTION: This on-ceiling-placed coals include coals which have major diameters of 15mm or less after carbonized, which account for 80 wt% or more of total coals, and which have a bulk density of 0.12 g/cm 3 or more. The bulk density is greater, a placement thickness is relatively smaller and the rate of short or small coals is higher to improve the diffusion efficiency of noises, while a specific surface area is larger to improve moisture control performance. The rate of the short or small coals is higher to make coals in layers, prevent the entry (blow) of outside air directly into a room and secure ventilation while maintaining air tightness. Thus, the ceiling reduces the impact noises of the floor while preventing dew condensation without excessively increasing the thickness of the ceiling portion. The ceiling is constructed using the preset thickness of coals for improved heat insulating property and heat storage property. COPYRIGHT: (C)2006,JPO&NCIPI
