A plurality of small beams 20 are erected at a predetermined pitch between a pair of opposing long side beams 12 in the frame 16. A ceiling panel 18 is attached to the lower surfaces of these small beams 20, thereby forming the ceiling 19 of the building unit 1. Each end of the beam 20
Each is fixed to the long side upper beam 12 via the edge 30 and the bracket 40.

The bracket 40 is, as shown in FIG.
It is attached to each long side upper beam 12 at a predetermined interval. The bracket 40 includes a mounting surface 41 facing the inside of the frame 16 and the flange portions 17A, 17B of the long side upper beam 12.
The mounting surfaces 41 are opposed to each other between the pair of long-side upper beams 12 in a state where the brackets 40 are fixed to the respective upper-side beams 12. I have. The joining surfaces 42 and 43 and the flange 17
Joining with A and 17B may be performed using fasteners such as bolts and nuts. Such a bracket 40 is
It is formed by bending a plate material such as a steel plate. Specifically, the mounting surface 41 and the joining surfaces 42 and 43
Is formed by bending and raising three ends of a plate member formed in a substantially T-shaped plane at right angles. Thereby, the mounting surface 41 and the joining surfaces 42 and 43 are orthogonal to each other, and the mounting surface 41 is orthogonal to the longitudinal direction of the small beam 20 when the bracket 40 is mounted on the long side upper beam 12. Has become.

As shown in FIG. 2 and FIG. 3, a pair of edge portions 30 along the long beams 12 are attached to these brackets 40. As shown in FIG. These pair of edge 30
Is made of a lightweight section steel having a U-shaped cross section with a concave groove 31,
The grooves 31 are fixed to the mounting surface 41 of the bracket 40 so as to face each other. The edge 30 and the mounting surface 41 are joined by screws 44 screwed into the edge 30 and the mounting surface 41.

Each groove 31 of such a pair of rims 30
Between them, a plurality of small beams 20 made of lightweight section steel having a rectangular cross section are provided. The thickness of the small beam 20 is, for example,
Both ends of one side surface are extended in the longitudinal direction, and the extended portion 21 is folded back to close the end surface of the small beam 20. Also, as shown in FIG.
The notch 22 corresponding to a thickness of 0 is formed, and when the end of the small beam 20 is inserted into the concave groove 31 of the edge 30, the small beam 20 is formed.
And the lower surface of the edge 30 are formed flush with each other. Thereby, the ceiling panel 18 can be horizontally attached to each lower surface of the small beam 20 and the edge 30. Note that the ceiling panel 18 of the present embodiment is made of two gypsum boards stacked one on another.

Both ends of the small beam 20, that is, the notch 22
Is formed at a height corresponding to the height of the groove 31 of the edge 30, and when the end of the beam 20 is inserted into the groove 31, the upper surface of the end of the beam 20 is Each is in surface contact with the upper surface inside the concave groove 31. This allows
By simply inserting the end of the beam 20 into the groove 31, the beam 20
Is positioned with respect to the edge 30 in a correct posture without tilting. The small beam 20 and the edge 30 are screwed into the upper surface of the edge 30 and the upper surface of the beam 20, respectively.
3 are connected.

In the thus constructed embodiment, the ceiling 19 of the building unit 1 is constructed in the following procedure. First, the pillar 11, the upper beams 12, 13 and the lower beams 14,
15 to form a skeleton 16 and a pair of long side upper beams 12.
The bracket 40 is attached to each. Bracket 4
0 is inserted into the upper beam 12 on the long side, and the respective joint surfaces 42, 4
3 is brought into surface contact with the flange portions 17A and 17B of the long side upper beam 12 and positioned and fixed. Then, the mounting surface 41 of the bracket 40 becomes a vertical surface, and the upper side beam 1
Each of the mounting surfaces 41 of the bracket 40 mounted on 2 comes to be in the same vertical plane. The mounting intervals of these brackets 40 need not correspond to the pitch of the small beams 20.

Next, the edge 30 is fixed to these brackets 40 with screws 44. That is, the screw 44 is fixed after adjusting the mounting height position of the rim 30 to the bracket 40 so that the lower part of the rim 30 protrudes below the long side upper beam 12 by a predetermined dimension. The adjustment of the mounting height is performed by moving the edge 30 in the vertical direction while keeping the edge 30 in contact with the mounting surface 41 of the bracket 40.
Thereby, a gap having a desired height can be easily formed between the upper beam 12 on the long side and the ceiling joint panel 51 installed therebelow. In addition, this ceiling joint panel 51
This is for connecting a ceiling panel (not shown) and a ceiling panel 18 of another adjacent building unit 5. Further, the gap between the ceiling joint panel 51 and the long side upper beam 12 prevents the deformation of each long side upper beam 12 due to an external force from being directly transmitted to the ceiling joint panel 51, and the ceiling panel 18 and the ceiling joint panel 51. In order to ensure the flatness of.

Then, the small beams 20 are sequentially bridged at a predetermined pitch between the pair of edge portions 30. At this time, when the end of the small beam 20 is inserted into the concave groove 31 of the edge 30, the upper surface of the small beam 20 comes into surface contact with the upper surface of the concave groove 31.
0 is held at the edge 30 in the correct posture. When the small beam 20 is arranged at a predetermined position in the longitudinal direction of the long side upper beam 12, the small beam 20 is fixed to the edge 30 by screws 23.

The ceiling 19 of the present embodiment has a ceiling portion formed by attaching small beams 20 to a pair of edge portions 30 in advance, and the upper beam 12 on each long side of the frame 16.
A bracket 40 may be attached to the skeleton 16, and a ceiling integrated with the framework 16 may be incorporated to fix the rim 30 to the bracket 40.

According to this embodiment, the following effects can be obtained. That is, since the small beams 20 are erected between the edge portions 30, the pitch of the brackets 40 does not need to correspond to the pitch of the small beams 20. Since the influence on the ceiling 19 can be reduced, the bracket 40 does not need to be strictly attached, so that the construction of the ceiling 19 can be facilitated.

Further, if the edge 30 is made of a light-weight steel, the weight can be reduced as compared with the case where a wooden material is used, so that the handleability can be improved. In addition, since the light-weight steel is more uniform than the wooden material, In the case of stable quality, the margin 30 can be obtained at low cost. Further, since the small beam 20 is installed between the concave grooves 31 of the edge 30, the small beam 20 can be securely attached even if the length is slightly different. Since it is not necessary to do so, the processing of the beam 20 can be simplified.

Further, since the small beam 20 is made of a lightweight section steel having a cylindrical cross section, the weight can be reduced as compared with the case where the section is made of a wooden material, so that the handleability can be improved, and the lightweight section steel is more uniform than the wooden material. Therefore, small beams of stable quality can be obtained at low cost.

The bracket 40 is attached to the long side upper beam 12.
Joint surfaces 42 fixed to the flange portions 17A, 17B of
43, the joining surfaces 42, 43 and the flange 17
Since the bracket 40 can be positioned in the correct posture with respect to the long side upper beam 12 only by making surface contact with A and 17B,
The bracket 40 can be easily attached.

Since the bracket 40 is formed by bending a plate material, it can be manufactured simply and at low cost. Furthermore, the mounting surface 41 of the bracket 40
Is vertical, so that the rim 30 is moved in the vertical direction while keeping the rim 30 in contact with the mounting surface 41.
The mounting height of the can be easily adjusted.

It should be noted that the present invention is not limited to the above-described embodiment, but includes other configurations capable of achieving the object of the present invention, and also includes the following modifications.
That is, the bracket is not limited to that of the above-described embodiment. For example, as shown in FIG. 4, an L-shaped bracket 61 may be used, and is provided with a mounting surface for mounting a marginal edge. If so, its shape is not particularly limited. As shown in FIG. 4, a wooden base material 62 is attached to the mounting surface 61A of the bracket 61, and
2, the edge 30 may be fixed with a wood screw 63 or the like. In this case, if the ceiling joint panel 51 is configured to be fixed to the wooden base material 62, the work of attaching the ceiling joint panel 51 at the construction site can be simplified.

In the above-described embodiment, the bracket 40 and the edge 30 are connected by the screw 44, but they may be fixed using other fasteners such as bolts and nuts. However, since the mounting position of the edge can be adjusted by fixing with screws, it is preferable to use screws.

[0029]

As described above, according to the present invention,
Since the small beams are installed between the edges, it is not necessary to adjust the pitch of the brackets fixed to the beams to the pitch of the small beams, and the effect of the mounting position and posture of the bracket on the mounting condition of the small beams is reduced. Since it is possible to install the bracket strictly, ceiling construction can be facilitated.
