摘要： PROBLEM TO BE SOLVED: To improve the sound insulation performance of the subject pannel with a light and low cost material by complexly integrating a sound absorbing plate made from inorganic grannular material and a sound insulating plate composed of a core layer formed of coal ash granular material and coal ash and upper and lower surface layers formed of coal ash and fibrous filler holding the core layer therebetween with a binder applied thereto, through air. SOLUTION: A sound absorbing material 1 is formed by hardening inorganic granular material and a fibrous filler 4 with a binder. A sound insulating plate 3 is formed by holding a core layer made of coal ash granular material formed by mixing coal ash and cement between both upper and lower surface layers made of fibrous binder 4, and hardening it with a binder. A sound absorbing and insulating pannel is manufactured by complexly integrating the material 1 and the material 3 through an air layer 2. Since the coal ash granular material is used as the core layer, the plate 3 has a high density and the sound insulation performance thereof is improved. With the constitution, the use of thermosetting resin used as a binder can be reduced, which provides the plate 3 with a high flame resistant characteristic.

摘要： PROBLEM TO BE SOLVED: To prevent the occurrence of a void easy to occur when sound absorption and insulation panels are arranged in parallel as much as possible without specially increasing dimensional accuracy. SOLUTION: A large number of sound absorption and insulation panels 10 are tightly arranged in a line in every direction, and sound absorbing plates 20 are arranged toward a construction site to construct a soundproof wall, A belt 26 is stuck on at least two outside surfaces adjacent to each other among outside surfaces 15, 15... of one frame 12, for example, the outside surface 15 and top side 16 or the outside surface 15 and bottom side 17. The belt 26 is formed of an elastic material such as hard rubber, felt or the like, so that the adjoining sound absorption and insulation panels 10 and 10 can be easily adhered to each other, Then, the adjoining sound absorption and insulation panels 10 and 10 are approached to each other, and when the belt 26 is held between the frames 12 and 12, the belt 26 is expanded and contracted to make it possible to fill up a void between the frames 12 and 12.

摘要： PROBLEM TO BE SOLVED: To provide a concrete sound insulating wall excellent in sound insulating effect, and to dispense with a withdrawing work in a formwork in the case of construction. SOLUTION: A sound insulating wall 8 is erected on an elevated foundation 6 and composed of a concrete wall 12 and a sound absorbing panel 10 unitedly attached to its front face. An adjacent sound absorbing panel 10 is attached at its end through a connecting metal fitting. Since the sound absorbing panel 10 is used as a placing form for the concrete wall 12, and after hardening of concrete, its removement is unnecessary, and at the same time as the hardening of concrete, the sound insulating wall 8 where the sound insulating panel 10 is joined to the surface of the concrete wall 12 is constructed.

摘要： PURPOSE:To doubly provide high workability and strength by way of improving water permeability by forming an inorganic surface of a composite material hardened by way of arranging strand type inorganic fiber impregnated with thermosetting resin on the whole or a part of an inorganic particulate layer consisting of resin covered sand covered with the thermosetting resin. CONSTITUTION:Resin covered sands are made by covering the surface of inorganic particulates more than 90weight% of which are within particle diameters of 0.75-1.0mm with thermosetting resin of a 1.5-5 weight part for an inorganic particulate 100 weight part. Additionally, a chop strand of inorganic fiber 3 impregnated with the thermosetting resin is prepared. Thereafter, a laminated body with the chop strand dispersed in it is made in the resin covered sands by sequentially and alternately splashing and laminating the resin covered sands and the chop strand by specified quantity each. A composite body 1 is formed by hardening the thermosetting resin by way of thermally curing this laminated body. Consequently, the particulates are connected to each other by point adhesion, a continuous cavity is left, cavities are formed between fiber bundles and the fiber bundles and the inorganic particulates, and they are laminated and integrated.

摘要： PURPOSE:To provide excellent strength, lightweight properties and safety by a method wherein a plurality of thin inorg. fiber layer mats undulated in the direction right-angled to the longitudinal direction thereof are mutually laminated so that the fibers are mutually entangled in the respective layers and between them to be oriented three-dimensionally at random. CONSTITUTION:Respective layers L1-L10 of inorg. fiber sheets are pressed and contracted so as to have a shape having many corrugated undulations. Since compression force is applied to the layers L1-L10 in the thickness direction thereof at the time of pressing and contraction, the thin inorg. fiber layers f1-f10 of the respective layers L1-L10 are directed in a three-dimensionally random direction and fibers become a mutually entangled state in the respective layers L1-L10 and between them. Since the thin inorg. fiber layers f1-f10 are fixed in this state by a binder, the thin inorg. fiber layers f1-f10 are directed in three- dimensionally various directions such as a horizontal direction, a vertical direction or an oblique direction in the obtained fiber aggregate. Therefore, sufficient yield strength is obtained to the force applied in the thickness direction and compression strength is enhanced.
