摘要： PROBLEM TO BE SOLVED: To lower the level of impact noises at low frequencies by providing a frame formed by assembling of girders, beams placed parallel to each other so that they couple the opposite girders together, and a floor board joined to the upper surfaces of the girders and beams, and fabricating the beam into a hollow closed cross section. SOLUTION: The end of each beam 23 is pushed into a lateral opening in a girder 2, the beams 2 and the girders 3 are coupled together by means of self-tapping screw s11, a coupling member 5 of an L-cross section is attached to the coupled parts of the girder 2 and the beam 3, and they are firmly coupled together by the self-tapping screws 11. In this case, the girders 2 are assembled into into a frame 6 of a rectangle or the like involving vertical and horizontal members, and the beams 3 are coupled to the opposite parts of the girders 2 to provide a frame of a rectangle or the like. A floor board 4 is placed in such a way as to abut to the upper flanged parts of the girders 2 and the beams 3 and is joined to the girders 2 and the beams 3 by self-tapping screws 12. Thus the use of the beam 3 of a closed cross section can effectively lower the level of impact noises at a low frequency that is characteristic of a floor structure 1 using a skeleton made of metallic shapes.

摘要： PROBLEM TO BE SOLVED: To remove a resin from vibration-damping sections whose mounting is defective and thereby reuse extruded aluminum sections by heating a laminate of a metallic material and a resin mounted on the surface of the metallic material and melting the resin to peel it off the surface of the metallic material. SOLUTION: When heating a laminate, the laminate is held so that the face on which a metallic material 1 is mounted comes to the top in a heating furnace and a molten resin 2 peels off and drops downward. In this case, a receiving member 3 is placed below so that the resin 2 lends on the member 3. The receiving member 3 is, for example, an aluminum foil which can be easily molded and introduced into the hollow part of long-size sections as a convenient material. The resin 2, heated in the heating furnace, peels off and drops onto the receiving member 3, so that the receiving member 3 has only to be drawn out after cooling. This method is applicable to especially, vibration-deadening sections consisting of the resin 2 mounted on the inner surface of the hollow part of long-size hollow sections.

摘要： PROBLEM TO BE SOLVED: To provide a damping section in which a damping sheet is thermally fused on the surface on which a conventional damping material sheet can not be thermally fused by loading a damping material sheet of high melting point on a section, heating the sheet, and after the thermal fusion, loading a damping material sheet of low melting point on the other surface of the section, and heating the sheet for thermal fusion. SOLUTION: A damping material sheet 12a on the high melting point side is inserted in a hollow part of an extruded section 11, and loaded on two surfaces across one corner part, and heated for thermal fusion with this side downward. When an aluminum extruded section 11 is of the kind to require the aging, the aging can be commonly achieved through the heating. After the extruded section is once cooled, the extruded section 11 is invested, a damping material sheet 12b on the lower melting point side is inserted in the hollow space of the extruded section 11, and loaded on the other two surfaces, and heated for thermal fusion. The heating temperature is below the melting point of the damping material sheet 12a on the higher melting point side so as to prevent the damping material sheet 12a from being re-melted and to prevent the resin from being dripped or peeled.

摘要： PURPOSE:To select a suitable material of a viscoelastic body in a simple manner with no computation as well as to remarkably enhance a vibration damping effect with the selected material by using the viscoelastic body whose complex shearing elastic modulus at the working temperature satisfies specified conditions. CONSTITUTION:In a vibration damping plate 1a, a viscoelastic body 3a is used, whose complex shearing elastic modulus G=G1+jG2 at the working temperature satisfies an expression I, wherein E represents the Young's modulus of the plate member 2 of the damping plate 1a. Since this damping plate 1a satisfies the conditions required by the first and the second expressions on G1 and G2, the loss factor of the damping plate becomes maximum in the range of audio frequencies. In addition, since the damping plate 1a satisfies the condition required by the third expression on G2/G1, it is possible to make the loss factor of the damping plate 1a equal to or more than about 0.05, so that its vibration damping effect can thereby be enhanced remarkably.

摘要： PURPOSE:To extend a working temperature range for a vibration damping device by setting the thickness of a viscoelastic body so that dissipation factor of the viscoelastic body at a prescribed temperature can fall within a prescribed range. CONSTITUTION:In a vibration damping device 1a, the thickness is set as 1mm so that the value of dissipation factor of a viscoelastic body 7a such as, for example, vinyl acetate-related resin at a prescribed temperature 5 deg.C can fall within a prescribed range. Thereby, even if the temperature of a structure 2 such as a floor panel becomes about 5 deg.C in the winter time, vibration of the structure 2 can be restricted sufficiently. By the way, when the temperature of the viscoelastic body 7a is high in the summer time and so on, the dissipation factor of the viscoelastic body 7a goes beyond its tolerance, so that a vibration damping device 1 equipped with a viscoelastic body 7, in which a prescribed temperature is set as 20 deg.C and the thickness is set as 50mum, is installed in the structure 2 in addition to the vibration damping device 1a. Thereby, in the summer time or in the intermediate period, the vibration damping device 1 can restrict the vibration of the structure 2, and in the winter time and so on, the vibration damping device 1a can restrict the vibration.

摘要： PURPOSE:To select construction materials for a viscoelastic body easily without calculating and restrict vibration of a structure sufficiently while using the viscoelastic body of the same construction materials by using the viscoelastic body in which Young's modulus and dissipation factor can satisfy a prescribed condition at a working temperature. CONSTITUTION:A viscoelastic body 8a, in which Young force E and dissipation factor eta can satisfy conditions as shown in equations I and II at a working temperature, is used. That is, in a damping device 1a, according to the equation I, the dissipation factor of the device 1a is set to be maximized in a low fre quency area of about 10 - 100Hz. In other words, the high dissipation factor can be obtained in the low frequency area and a damping effect can be maxi mized, so that it is optimum for restricting low frequency vibration of a struc ture 2 such as a floor panel. Since the dissipation factor of the viscoelastic body 8a is more than 0.2 according to the equation II, the dissipation factor of the damping device 1a is set to be more than 0.05 in the low frequency area of about 10 - 100Hz. That is, a condition of the dissipation factor, where the vibration damping effect is exhibited noticeably, can be satisfied so that vibration of the structure 2 can be restricted sufficiently.

摘要： PURPOSE:To obtain a wide vibration control frequency band by mounting a vibration controller having the vibration absorbing characteristic corresponding to resonance frequency of a structure, thereafter repeating the process of mounting a vibration controller having the vibration controlling characteristic corresponding to new resonance frequency of the structure after the vibration controller is mounted. CONSTITUTION:When a vibration controller 1 which corresponds to a frequency F0, is mounted close to a point of maximum amplitude of resonance frequency F0 of a structure 2 such as a floor panel, etc., the vibration frequency characteristic curve (b) of the structure 2 after the vibration controller is mounted, has peaks at the frequencies F1, F2 on adjacent both sides of the frequency F0. Vibration absorbers 1a, 1b which correspond to newly induced resonance vibration frequency F1, F2, are further mounted in the neighborhood of the vibration controller 1. Thus, the band width W0 of vibration absorption frequency of the vibration controller 1, the band width W1 of vibration absorption frequency of the vibration controller 1a, the band width W2 of vibration absorption frequency of the vibration controller 1b, can suppress the vibration of the structure 2 by group 7 of the vibration controller having a sufficiently wide band width WX.
