[0007]

According to the present invention, there is provided a wall panel for a building in which an outer wall and a sound absorbing material are integrated by the following means. Precast concrete panel (hereinafter referred to as PC version) is a concrete pre-made product. In the case of a molding plate such as a precast concrete panel, a mounting structure for mounting a sound absorbing material inside and a space for securing a sound absorbing performance are formed. The PC plate having the shape and the sound absorbing material are integrated. In the PC version, it is also possible to integrate a sound absorbing material into a form during concrete production by casting concrete. In the existing PC plate, a frame having a function of holding a space and mounting a sound absorbing plate is mounted inside the plate, and the sound absorbing plate is mounted via the frame. In the case of a wall member requiring a base at short intervals, a base frame that bears the outer wall structure is assembled, and the wall member and the sound absorbing material are attached. Note that, in any of the cases (1) to (4), the space formed inside performs a function for ensuring sound absorption performance.

A mounting portion having a peripheral wall portion and a step portion is formed inside a wall member made of a PC plate. Then, a sound absorbing material formed into a board shape such as glass wool or a porous ceramic type sound absorbing material having good sound absorbing performance is fitted between the steps in the adjacent mounting portion and attached to the inside of the wall member to provide an air layer. The wall panel of the present invention is integrally formed.

Prior to assembling the wall for the building, a steel frame is constructed in which beams are stretched to each floor level of the building. First, mounting pieces are mounted on the lower and upper surfaces on the outer side of the upper and lower beams. Next, the above-mentioned wall panel carried into the construction site is lifted by a crane, and is brought close to upper and lower beams horizontally stretched to the height of each floor. Bolts are inserted into the bolt holes on the side of the wall panel approached, and the wall panels are sequentially attached to the outside of the beam. The attachment of the wall panel to the beam is extended in the vertical direction from the horizontal direction, and a building whose outer peripheral wall is covered with a wall body made of the wall panel is constructed.

Most of the noise generated in the constructed building is absorbed by the sound absorbing material provided inside the wall member.
Part of the noise transmitted through the sound absorbing material is diffused by an air layer formed between the wall member and the sound absorbing material according to the frequency characteristics. As a result, if the wall panel of the present invention is applied to a wall body of a garbage incinerator or the like, it is possible to absorb and block the propagation of internal noise generated due to ventilation or the like to the outside. Moreover,
Since the outer wall surface of the wall is surrounded by the wall member made of the PC plate, it has high rigidity and durability, and also has fire resistance.
