する方法が一般に用いられている。2. Description of the Related Art In recent years, wood soundproof flooring for direct upholstery, which is constructed directly on a concrete slab, has been used in middle and high rise houses such as apartments and condominiums. This wooden soundproof flooring for upholstery is provided with a cushioning material on the back side to improve soundproofing, so when placing heavy objects such as furniture, electric appliances, piano, etc. on the wall, the furniture tilts toward the wall side Sometimes. Therefore, in order to prevent the sinking phenomenon, a method of laying a plywood (so-called joist) having a width of 30 to 60 mm on a concrete slab near a wall and then laying a floor material thereon is generally used. .

発明に到達した。The inventors of the present invention have conducted intensive studies to solve the above-mentioned drawbacks. As a result, the use of an elastic sheet instead of plywood as the joist material has improved the sound insulation performance of the joist material. That the elastic sheet can be folded without separating the elastic sheet so that it can be used as a joist when construction of anti-wall damping material can be performed at the same time. The present inventors have found that by providing a protected adhesive layer, it is possible to obtain a joist for use in a straight wood-based soundproof flooring material with good workability, and arrived at the present invention.
