ようにされているから、機能的な美観を損わない。When assembling the ceiling frame, the upper projection of the joining member is fitted into the fixing through hole of the main transverse member, and the cut and raised piece of the joining member is inserted into the cut and raised piece of the main transverse member. If the main transverse member and the joining member are temporarily fastened only by inserting and engaging, even if the end of the main transverse member is joined to the joining member whose position has not been determined yet, the temporary fastening action is provided. It is possible to release the hand from the joint portion and shift to another operation, and this temporary fixing operation facilitates the assembling operation. Furthermore, when joining the sub-horizontal member to the parallel main main member whose position is temporarily determined, the hanging piece of the sub-horizontal member is inserted into the sub-horizontal member hanging piece penetration hole of the main horizontal member and the sub-member of the joining member. The temporary stop state can be obtained only by inserting the suspension member into the escape hole of the hanging piece, and this operation also contributes to the increase in ease of the assembling work. As described above, the joint portion of the main horizontal member and the connection portion of the sub-horizontal member are securely joined, and the length between one lattice unit of the main horizontal member and the sub-horizontal member to be joined is determined. Since the relative position and angle between the main and sub-members whose ends are joined to the joints will be maintained in a fixed state, the unit lattice by the ceiling frame is accurate. Since the shape is maintained, the work of correcting the position of the ceiling frame is extremely insignificant, and when installing the ceiling plate created with a certain size, there is an error in the installation size of the ceiling plate on the main horizontal member. This does not make the installation difficult and does not cause distortion of the ceiling plate later. The ceiling frame of the present invention is structurally structured such that the main horizontal member and the sub-horizontal member constitute each side of the unit lattice.
When viewed from indoors, the secondary horizontal member is located behind the ceiling plate and is not exposed indoors, but is arranged in parallel and the lower edge of the main horizontal member that contains the equipment for building equipment is inside. It will appear to form a parting band, and the main transverse member is unlikely to be deformed as described above, and the joint joint thereof is also kept linear, so that a functional aesthetic appearance is obtained. Do not spoil.
