摘要： PROBLEM TO BE SOLVED: To provide a sound absorbing structure unit excellent in a sound absorbing coefficient as a sound absorber for road traffic noises. SOLUTION: This sound absorbing structure unit 11 comprises a hollow frame body and a sound absorber 14 placed in the hollow part of the frame. In this case, the hollow frame body comprises a frame part 12, which covers the back and a part of each side of the sound absorber 14 as seen from a cross section perpendicular to its longitudinal direction, and a porous plate part 13 covering at least the front and a part of each side of the sound absorber 14, with the frame part 12 and the porous plate 13 together forming the hollow part. Further, the front of the sound absorber 14 has a projecting shape, and the porous plate part 13 has a projecting shape matching it. The units 11 are used being connected together at their connections 16a, 16b along their cross direction, with a space (s) formed between the adjacent porous plate parts at their junction. Since the sound absorber 14 is shaped to project, its surface area facing a sound source is large, and sounds impinging on the space (s) are also absorbed by the sound absorber 14.

摘要： PROBLEM TO BE SOLVED: To enhance vibration damping performance of a vibration control shape in the vibration control shape formed by sticking vibration control resin on a hollow shape with high rigidity constituted of a rib connecting a pair of face plates therewith. SOLUTION: The thickness t1 of a rib 1 of a hollow shape is formed thinner than the thickness t2 of face plates 2, and vibration control resin 3 is stuck thereon. The thickness t1 of the rib 1 is formed thinner than the thickness t2 of the face plates 2 to make it possible to further enhance vibration damping performance additional efficiency by sticking the vibration control resin on the flat section of the rib. Since static rigidity of the hollow shape is not so relied on the thickness t1 of the rib 1, high vibration damping performance can be obtained without lowering the rigidity of the hollow shape so much. When the vibration control resins is also stuck on the insides of the face plates 2, the coincidence phenomenon is controlled, and the generation of the lowering phenomenon in sound transmission loss in specific frequency area can be prevented.

摘要： PROBLEM TO BE SOLVED: To thermally fuse a vibration control material sheet without causing positional displacement on an inclined face by providing a lug locking the lower end side of the vibration control material sheet and preventing a deviation at the time of thermal fusion on the thermal fusion face of the vibration control material sheet. SOLUTION: At the time of vibration control material execution, an aluminum hollow shape is kept at the inclined attitude, a valley-folded vibration control material sheet 13b is inserted and mounted on the chamfering section 11a and rib section 12b in the hollow shape, and a vibration control material sheet 13a is mounted on the outer face side of a rib face 12a so that the lower end of the vibration control material sheet 13a is located on the upper side of a projection 15. The aluminum hollow shape is heated in the inclined attitude, and the vibration control material sheets 13a, 13b... are thermally fused. The chamfering section 11a and the rib section 12b are formed into a V-shape, and the vibration control material sheets 13b... are surely thermally fused at these positions without causing displacement. The vibration control material sheet 13a on the rib section 12a is prevented from slipping down at the time of thermal fusion by the lug 15, and it is surely stuck by thermal fusion.

摘要： PROBLEM TO BE SOLVED: To obtain damping structures including truss aluminum extruded shapes and π-type aluminum extruded shapes which excel in damping characteristics, by damping the hollow part of a shape with a damping resin. SOLUTION: Many rectangular damping resin plates 10 are placed in series on a plastic film 11 which is longer than a damping shape 1 and pasted with an adhesive to form a continuum 12. The width of the rectangle depends on the width of a rib 4 or face plates 2, 3. However, the appropriate length of the rectangular damping resin plate 10 is about 1m. Since a resin plate longer than that produces a clearance in the interface with the interior of the hollow part due to warp, etc., and involves air, it should be cut to a length enough to obtain a flat rectangle. The continuum 12 is inserted into the hollow part 7 with the damping resin 10 faced down. The damping resins 10 can be inserted while being butted together.

摘要： PURPOSE: To provide a vibration restraining device which can cope with the change of an ambient temperature in use. CONSTITUTION: Two sheets of plate springs 12 and 13 different in thickness are projected in parallel, keeping an interval with each other in both right and left directions from the support 14 provided on an structure 11, and these plate springs 12 and 13 are joined with each other into stratified form by viscous elastic member 19, and plumbs 17 are attached, severally, to the free end of the plate spring 12, and the plate springs 12 and 13, the viscous elastic material 18, and the plumb 17 are arranged symmetrically about the support 14. By constituting this vibration restraint, with two sheets of plate springs 12 and 13 different in thickness, the position of the viscoelastic material 18 is separated from the position of the center axis of the plate spring structure, so the influence of the modulus of rigidity of the viscoelastic material 18 having on the natural frequency of the plate spring structure becomes small, and the change of the natural frequency of the plate spring accompanying the temperature change decreases. Accordingly, this can exhibit stable performance practically without being affected by the ambient temperature used.

摘要： PURPOSE:To prevent radiating noise, vibration unpleasantless, rattling and the like of furniture by joining a plurality of plate springs together in a laminate manner with viscoelastic body or viscous body, and fixing a dynamic vibration reducer with weights disposed at the ends thereof to a steel frame and/or steel bars. CONSTITUTION:A frame 1 and bars 2 are formed of a steel plate having a groove- shaped cross section. A wooden surface member 4 is fixed to a frame body which is constituted of the steel frame 1 and the plurality of steel bars 2 disposed across the frame 1. A dynamic vibration reducer 9 is attached to a flange of the bar 2. If impulsive excitation force due to jumping, running and the like of a person is exerted on the panel surface member on a floor, the frame body and the surface member are freely vibrated in an integral manner. A plate spring or the like of the dynamic vibration reducer is resonantly vibrated due to the vibration of the steel frame 1 and/or the steel bars 2, and vibration energy of the steel frame 1 and the steel bars 2 is converted into thermal energy owing to shear deformation of a viscoelastic body according to the change of the plate spring due to the resonant vibration, to be discharged to the atmosphere. Consequently, it is possible to restrain vibration of the floor panel.
