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 provide a welding method of a vibration damping section member capable of securing good weld penetration by way of giving no adverse effect to weldability at the welding, without lowering its damping property so much, even in case of this damping section stuck with a damping resin material on a thin aluminum plate of less than 2mm as well as enabling it to prevent any possible deterioration of bead of bead form due to an excessive weld heat input, thereby making good welding operability securable. SOLUTION: In time of welding a vibration damping section member 1 stuck with a damping resin material on an least one side of an aluminum or aluminum alloy plate 2, it is welded at a straight polarity ration ranging from 5 to 20% by an alternating current pulse MIG welding process which supplies a reverse polarity arc and a straight polarity arc alternately from the backside of a surface where damping resin material 3 of the aluminum or aluminum alloy plate 2 is stuck fast. In this connection, in this damping resin material 3, each hole 3a is formed in respective positions where plural pieces of first line rows 4 extending in the first direction and plural pieces of second line rows 5 extending in the second direction being intersected with the first direction, within the surface.

摘要： PROBLEM TO BE SOLVED: To provide an exterior structure for a building capable of maintaining over a long period the effect of reducing noises caused by rain, without using additional members. SOLUTION: The exterior structure 1 for a building comprises a metallic plate 2 and a heat insulating material 3 which are affixed to each other with a viscous adhesive 4 made fibrous and having elasticity. The viscous adhesive 4 having elasticity acts as a spring to absorb vibration to reduce noises caused by rain. Even if different kinds of materials are affixed and integrated together, stresses can be repeatedly absorbed by the elasticity. Further, because the fibrous viscous adhesive 4 is so formed that numerous fibers are twisted together, vibration can be absorbed or damped in numerous spaces formed between the fibers, whereby the effect of damping the vibration and the effect of absorbing impacts can be enhanced.

摘要： PROBLEM TO BE SOLVED: To improve the sound absorbing coefficient by preventing deterioration or breakage of a protection film enveloping a fibrous sound absorbing material and forming a surface air layer by giving an adequate clearance between the fibrous sound absorbing material and a porous board in a sound board construction comprising a frame member, a porous board portion and the fibrous sound absorbing material placed in a hollow portion of the porous board. SOLUTION: A linking portion (steped portion) 12 is formed at the side face of a fibrous sound absorbing material 3, and a linkage receiving portion 13 for receiving the linking portion 12 is integrally formed at the inner side of a frame portion 4. In this way, the protection film 2 does not contact the porous board 5, deterioration or breakage due to vibration or cleaning can be prevented, and a surface air layer 10 can be created between the fibrous sound absorbing material 3 and the porous board 5 thereby improving the sound absorbing coefficient. This sound absorbing board construction can be used, for example, as a rear surface sound absorbing board which is suspended downward below a girder of an elevated bridge.
