For example, at a construction site, an operator hits the fixing portion 12 of the fixture 1 against the side surface of the rafter 3 and drives the fixing portion 12 into the side surface of the rafter 3 with a hammer H. In this embodiment, two fixtures 1 are provided for one eaves tip placement member 4. Further, the length of the contact pieces of the first position defining portion 14 and the second position defining portion 15 is longer than the length of the fixing portion 12 (nail-shaped portion), and the tip of the fixing portion 12 is The contact pieces of each of the first position defining portion 14 and the second position defining portion 15 can be brought into contact with the lower surface and the tip surface of the rafter 3 in a state of hitting the side surface of the rafter 3.

Then, the operator lifts the eaves-placement member 4 to which the construction jig 2 is attached and attaches the hook portion 23 of the construction jig 2 to the temporary support portion 13 of the fixed fixture 1 described above. It is temporarily supported by being hooked on the temporary support portion 13. Since the eaves tip arranging member 4 is hooked, the worker can remove his or her hand from the eaves tip arranging member 4, and can start another work. In the temporary support state in this example, a clearance is formed between the height adjusting portion 24 and the lower surface of the rafter 3.

Next, the worker fastens the temporarily supported eaves tip arranging member 4 to the rafter 3 using a screw or the like. At this time, the operator lifts the eaves locating member 4 so that the gap between the height adjusting portion 24 and the lower surface of the rafter 3 is eliminated, and the eaves locating member 4 is adjusted in height (positioning).

Alternatively, the position of the lower side of the temporary support portion 13 of the mounting portion 1 may have a height adjusting function. That is, the position of the upper end surface of the eaves tip arranging member 4 may be defined by abutting the upper end surface of the eaves tip arranging member 4 on the lower side of the temporary support portion 13. However, also in this structure, by providing a portion having the same shape as the height matching portion 24, when the eaves tip arranging member 4 is lifted, the eaves tip arranging member 4 separates from the tip surface of the rafter 3. Defects (rolling) can be suppressed.

Further, as another aspect of the construction jig 2, it is possible to adopt a configuration in which the hooking portion 23 is not provided and the height adjusting portion 24 is provided. With such a configuration, although the eaves tip arranging member 4 cannot be temporarily supported, the height of the eaves tip arranging member 4 can be easily adjusted by the height adjusting portion 24. Further, it is possible to avoid the cost increase due to forming the step portion or the like on the eaves tip arranging member 4 itself.

When an elastic body is provided in the receiving portion 22 of the construction jig 2 and the eaves locating member 4 is received by the elastic body, the elastic force of the elastic body causes the eaves locating member 4 to move. The upper end surface may be pressed against the lower side of the temporary support portion 13 so that the position of the upper end surface of the eaves tip arrangement member 4 can be regulated.
