Claims

[Scope of Claim for Utility Model Registration] 1. A soundproof wall structure constructed by combining a plurality of soundproof panels, in which each soundproof panel is formed into a box-like exterior by protruding flanges on the four peripheries of the body of the exterior board. It consists of a board and a sound absorbing material loaded into this box-shaped exterior board, and the flange of one adjacent soundproof panel and the flange of the other soundproof panel are placed between both soundproof panels with these flanges in between. A soundproof wall structure joined by removably interposed tightening connecting fittings. 2 The above-mentioned tightening connection fitting has an eccentric shaft which is fixed by a rotating shaft in one of the soundproof panels, a base end of which is fitted onto the outside of the eccentric ring so as to be relatively rotatable, and a hook is formed at the distal end. A tightening arm that can be retracted through a slit opened in the flange of one soundproof panel, and a hook provided in the other soundproof panel that protrudes through the slit opened in the flange of the other soundproof panel and is hooked. A soundproof wall structure according to claim 1, which comprises a locking pin. 3. Each soundproof panel is provided with a grid-like or net-like support on the surface side of the sound-absorbing material, and the peripheral edge of this support is fixed to the flange of the exterior plate. The soundproof wall structure according to item 2. 4. The soundproof wall structure according to claim 1, 2, or 3, wherein the sound absorbing material of each soundproof panel is made of glass wool.
