The basic H-shaped steel, struts, and beams There is known an assembly type soundproof box constructed by inserting soundproof panels one by one into the built frame.
Moreover, after driving a support pile into the ground, a structure is used in which a soundproof wall structure is constructed by setting up a column in the vertical direction and attaching a panel covering material. However, it takes a lot of time to drive the support pile into the ground, and there is also noise in driving the pile, and it is necessary to assemble the columns to form the panel covering material vertically on the wall, which takes time and money. There was a problem.

  In addition, since it is more effective for the sound barrier to have a certain amount of weight, the sound barrier is constructed by joining together one heavy plywood made of iron plate, air layer, glass wool and punching metal, and has a certain sound insulation effect. Construction walls were used. However, there is a problem that the structure is heavy and construction is difficult and expensive. Furthermore, due to the heavy weight, it was necessary to pay attention to safety during construction and maintenance.

  In addition, the soundproof wall is transported to the construction site when in use, and is constructed on the soundproof wall by being locked to the outside of the scaffold using mounting brackets attached to the scaffold. After that, it is used as a temporary wall that is repeatedly installed and removed in such a manner that it is removed from the scaffold and stored in a stacked state until the next use. Therefore, there has been a demand for a soundproof wall structure that is easy to assemble and that can be used repeatedly.
