Reference numeral 1 shown in the drawing is an inner pipe having a retaining groove 4 having a bolt mounting hole 2 at the outer end thereof. Reference numeral 5 is an outer pipe that is inserted into the outer side of the inner pipe 1 so as to be expandable and contractible. A mounting substrate 7 having a bolt mounting hole 6 at the outer end is fixedly provided, and the inner pipe 1 is prevented from coming off near the inner end thereof. Tightening bolts 8 in the range of expansion and contraction are provided so as to face the groove 4, and stoppers 9 for preventing removal are provided inward.

落下事故を未然に防止することができる。When the scaffolding base metal fitting for construction according to the embodiment of the present invention is used, as shown in FIG. 3, for example, an embedded metal fitting is provided on the inner surface of the concrete skeleton C in the opening of the elevator chamber A. B and B are embedded at predetermined positions and intervals in advance, and the inner pipe 1 and the outer pipe 5 of the scaffolding base metal fitting are expanded and contracted according to the opening width of the frame C to adjust to a predetermined length, and the tightening bolt 8 Tighten and fix with. In this state, the bolt fitting holes 2.6 are aligned with the embedding metal fittings B on the inner surface of the opening, and both ends of the bolts D are attached. At the time of mounting, it may be bolted by using a driving type anchor. After this, a plywood formwork E with a splint or a plywood scaffolding plate can be laid on the scaffolding base metal to construct a work scaffolding. By carrying out curing as well as a work scaffold at the opening of the slab by such a construction method, it is possible to prevent a fall accident during construction or the like.
