[Problems to be solved by the device]

 The above-mentioned conventional method for attaching a hanging tree to a horizontal member, attaching an upper board to the hanging tree, attaching a lower board to an upper board, and attaching a ceiling panel to a lower board are all performed. Since this is done at the construction site, and there are many nailing parts at the construction site, especially because the work is performed at high places, there is a problem that the danger is high and the workability is extremely poor. In addition, the ceiling panel and the floor plate above it interrupt the space between the lower floors and the upper floor, but the sound from above and below is transmitted through the ceiling panel and the floor plate above it, and there was a problem with sound insulation. .

The present invention solves such a problem, and makes it possible to easily install a ceiling panel in a wooden building and to improve sound insulation between the lower floor and the upper floor. The purpose is to

[Means for Solving the Problems]

 In order to solve this problem, the present invention provides a frame structure for mounting a ceiling panel, which is made by assembling a cauldron, between horizontal members such as beams that are parallel to each other in a wooden building. A ceiling panel is attached to the lower surface of the body, and a sound insulating surface material is attached to the upper end of the frame body so that a space between adjacent horizontal members can be vertically moved by the surface material. The idea is to partition.

With this configuration, a frame body for mounting a ceiling panel, which is made by assembling a coffin material, is arranged between horizontal members such as beams parallel to each other, and the ceiling panel is provided on the lower surface of the frame body. Work efficiency can be improved by mounting. In other words, by unitizing the cauldron for ceiling panel mounting, the hanging tree is attached to the horizontal material, the upper cauldron is attached to the hanging tree, and the lower cauldron is attached to the upper casket. It is possible to greatly improve the workability on the site and improve the safety of the work as compared with the case where the installation is done at the construction site. In particular, according to the present invention, the space between the adjacent horizontal members is divided into upper and lower parts by the sound insulating face material, so that the sound insulating property between the lower floor and the upper floor is obtained.
