DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. 1 to 5,
Reference numeral 1 is a horizontal member such as an eaves girder or a gable beam which is received by the upper end of the pillar 2 and fixed to the upper end of the pillar 2 by nailing or the like.
On the other hand, the ceiling beams 3 and the rafters 4 are fixed via the binding members 5.

The binding metal fitting 5 will be described in detail. The binding metal fitting 5 is formed by bending a metal plate, and has two substantially triangular side plate portions 6 sandwiching the rafters 4 and a lower end on one end side of the side plate portion 6. An inclined plate portion 7 which connects the two and the lower end is inclined in a direction away from the horizontal member 1, a plate portion 8 for positioning which is continuously provided at the upper end of the inclined plate portion 7, and the two side plate portions 6
Of the side plate portions 6 in a state of being biased toward one end side of each side plate portion 6 in a length range of approximately half of the upper end of the plate portion 8. On the other hand, the upper end of the inclined plate portion 7 is bent so as to be inclined so as to be inclined at a gentle angle, and the plate portion 9 is continuously bent at a right angle to the side plate portion 6. This binding member 5 is attached to the end portion of the ceiling beam 3 before the ceiling beam 3 is placed on the horizontal member 1. Specifically, the ends of the two parallel ceiling beams 3 are brought into contact with the outer surface of one end of each side plate portion 6 and the lower surface of the plate portion 9 and nailed to the plate portion 9 so that both ends of the ceiling beams 3 parallel to each other are the binding metal fittings. Connected by 5. At that time, the end portion of the ceiling beam 3 is aligned with the end portion 9a of the plate portion 9 of the binding fitting 5. Then, when the ceiling beam 3 is placed on the horizontal member 1, the positioning plate portion 8 is provided in the positioning recess 11 which is formed in the ceiling beam 3 mounting portion of the horizontal member 1 with the bottom surface being inclined in advance. Is inserted and the ceiling beam 3 is positioned. At this time, the ceiling beam 3 is hung while the inclined plate portion 7 hits the upper end corner portion of the horizontal member 1, and the positioning plate portion 8 is fitted into the positioning recess 11 and placed on the bottom surface of the recess 11. The alignment of the ceiling beam 3 with respect to the horizontal member 1 is completed when the ceiling beam 3 is placed on the horizontal member 1. In that state, the inclined plate portion 7 is fixed to the horizontal member 1 by nailing 10.

In this way, the sag 4 is fitted between the two side plate portions 6 and 6 of the binding fitting 5 fixed to the horizontal member 1, and the sacrifice tree 4 is placed on the plate portion 8 to form the two side plates. The side plate 6 and the barrel 4 are fixed by nailing 10 on the other end of one side plate 6 of the parts 6, 6. In addition, the rafters 4 are side plate portions on both sides of the substantially U-shaped positioning metal fittings 12 which are attached to the rafters 4 at the position of the binding metal fittings 5 by nailing 10 in advance.
The end surface of 13 is positioned by abutting the end surface of the side plate portion 6 of the binding metal fitting 5 on one end side, and is fixed to the purlin at the position of the ridge. By the way, the positioning bracket 12 is a bottom plate portion.
14 is fixed to the rafter 4 with 10 nails.

In the above manner, the ceiling beam 3 and the rafters 4 are fixed on the horizontal member 1 through the binding members 5, and the ceiling beams 3 and the rafters 4 are arranged in the longitudinal direction of the horizontal member 1. It is provided at appropriate intervals.

[0011]

As described above, according to the present invention, the positioning of the ceiling beam and the rafters with respect to the cross members such as eaves girders and girders can be applied to the fastening fittings and the fastening fittings. This can be easily performed by the positioning metal fittings attached to the rafters so as to be in contact with each other, and the work efficiency at the time of roof assembly can be significantly improved.
