〔The invention's effect〕

In the invention of claim 1, a flange portion is provided on the upper side of the cross section.
A number of structural members 1 having 1a, 1a are provided side by side, and the longitudinal ends of the main mounting material A for ceiling, in which support pieces 3, 3 are formed at both ends in the axial direction,
It is placed on the structural material 1 so that its longitudinal direction is orthogonal to the longitudinal direction of the structural material 1, and both ends in the longitudinal direction are fixed on the structural material 1 with fixing brackets. A rectangular ceiling plate C is placed between A and the facing structural members 1, 1 from above, and a metal folding member 13 is placed on the structural members 1, 1,. By using a roof and a ceiling structure with a plate-shaped roof D, firstly, a ceiling just below the metal roof D can be laid from above the roof D, and secondly, a work scaffold can be used at the time of ceiling construction. Thirdly, there is an effect that the ceiling structure can be simplified, and thirdly, the total construction cost of the roof and the ceiling can be reduced.

These effects will be described in detail. First, a large number of structural members 1 having flange portions 1a, 1a on the upper side of the cross-section are provided side by side, and the longitudinal direction of the main mounting material A for a ceiling having supporting sides 3, 3 formed at both ends in the width direction. The ends were placed on the structural material 1 such that the longitudinal direction was orthogonal to the longitudinal direction of the structural material 1, and both ends in the longitudinal direction were fixed on the structural material 1 with the fixing brackets E, so that the ceiling The mounting material A is firmly attached to the structural material 1 and its supporting side 3
And the flange portion 1a of the structural material 1 becomes a piece on which the ceiling plate C can be placed from above, whereby the ceiling plate C can be placed and fixed on the roof D, specifically, from above the structural material 1. Yes, and thus the entire ceiling can be laid. Therefore, since the construction of the ceiling and the roof D can be performed by the same contractor, there is no need for a roofing specialist and a ceiling construction specialist as in the past, and only the roofing contractor can perform the construction.
There is an advantage that the construction cost can be greatly reduced.

Furthermore, in the past, scaffolding was always required at the time of ceiling construction, and the transfer of scaffolds to the site, scaffold assembly, scaffold dismantling, transport to another location after dismantling, the time and cost required for this depending on the construction site , But in the present invention,
Since the ceiling can be laid from the upper side of the roof D, there is a great advantage that such a scaffold relationship can be completely eliminated.

Further, in the present invention, the structural materials 1,1,
Can also be used as a member for laying the ceiling, so that the structure of the roof and the ceiling structure can be remarkably simplified, and the effect that the construction can be carried out at low cost is also achieved.

In the roof and ceiling structure of the present invention, the structural material 1 is exposed when viewed from the lower surface side, but it can be sufficiently used in a gymnasium, a factory, an exhibition hall, and the like, not in a company or an office.

In addition, since the ceiling plate D is laid using the flange portions 1a, 1a on both sides of the upper side of the cross section, the lower portion of the structural materials 1, 1 is almost exposed. If it is large, it has strength.
An overhead crane and these various devices can be attached, and the structural material 1 can be used effectively.

Next, in the invention of claim 2, a large number of structural materials 1 are provided side by side so that the longitudinal direction of the metal roof D is the same as that of the metal roof D, and the supporting sides 3, 3 are provided at both ends in the width direction. The main mounting material A for the ceiling is formed so that the longitudinal direction is orthogonal to the longitudinal direction of the structural material 1 and the flange portion 1a of the adjacent structural material 1
A plurality of ceiling boards C are placed between adjacent ceiling main mounting materials A, A at appropriate intervals and fixed to the surface with fixing brackets E, and then the plurality of ceiling boards C are covered. to, long shingle D ₁ a structural material 1,1, ... and葺成construction above, sequentially, to appropriate intervals, by which the construction methods of the roof and ceiling structure construction repeat these, First, the construction of the roof D and the ceiling can be performed at substantially the same time. Second, the roof D and the ceiling can be constructed by the same installer. Third, the construction of the ceiling can be performed without any scaffolding. There are effects such as being able to be inexpensive.

To elaborate on these effects, firstly, laying the ceiling board C against appropriate intervals, then it was葺成roof plate D ₁ of the metal in the appropriate interval locations, conventionally,
Indeed, the ceiling construction was performed by another contractor after the roof D was roofed. However, according to the present invention, when the roof D can be roofed, the ceiling construction can be performed at the same time, making the construction simple and quick. It has the greatest effect possible.

In particular, after the ceiling construction, since the location serves as a safety net or a scaffold, the subsequent roof D construction,
It is as if there is a foothold, and the safety of workers can be secured.

Furthermore, according to the present invention, since the roof and the roof D can be constructed by the same trader, there is no need for a roofing specialist and a ceiling construction trader as in the past, and only the roofing trader is required. It has the advantage that construction costs can be greatly reduced.

In addition, as a reason for shortening the construction period and reducing the construction cost as described above, scaffolding is always required at the time of ceiling construction, scaffolding to the site, scaffold assembly, scaffold dismantling, dismantling Although the transportation and the time and cost required for such transportation are enormous depending on the construction site, the present invention can point out that such a scaffold relationship can be completely eliminated.

In addition, the main mounting member A for the ceiling can be fixed to the structural member 1 with only the fixing bracket E, and there is an advantage that the ceiling main mounting member A can be easily and quickly mounted.
