PROBLEM TO BE SOLVED: To provide a simple building capable of being constructed with good workability.SOLUTION: A simple building 1 includes a principal rafter tool 7 including a principal rafter cover 17, a coupling material 19, a back plate 18, and a screw 21. The principal rafter cover 17 has a length approximately equal to those of frames 15 opposite to each other between both roofs 3, 5, is disposed so as to be stretched on the opposite frames 15 of both roofs, and includes a coupling material fitting part 27 to fit to the coupling material 19. The coupling material is disposed so as to be stretched under the opposite frames 15 of both roofs, and includes a coupling material fitted part 35 to be fitted to the coupling material fitting part 27 of the principal rafter cover 17. A screw hole 32 is formed on the back plate 18, the back plate 18 is fitted to the principal rafter cover 17 freely slidably in the longer direction, and the screw hole 32 is exposed downward from the principal rafter cover 17. The coupling material fitted part 35 of the coupling material 19 is elastically-repulsively engaged from below with the coupling material fitting part 27 of the principal rafter cover 17. A screw insertion hole 45 is formed in the lower face of the coupling material 19. The screw 21 inserted from under to the screw insertion hole 45 of the coupling material 19 is screwed together to the back plate 18 to fix the principal rafter cover 17 and the coupling material 19.SELECTED DRAWING: Figure 1 |
