DESCRIPTION OF THE PREFERRED EMBODIMENTS A temporary passage for a construction site according to the present invention will be described with reference to FIGS. The temporary passage includes a plurality of passage members 1 and a plurality of connection members 2, and is formed by arranging the plurality of passage members 1 continuously in the passage direction and connecting boundaries of adjacent passage members 1 with the connection members 2. Is done. The passage member 1 is provided with baseboards 4 on both side edges of a substantially long plate-like floor material 3 which is long in the passage direction, and the floor material 3 is such that long concave portions and convex portions are alternately continuous in the short side direction. Although it is integrally formed of a light metal plate such as aluminum, it may be formed by connecting several members. The baseboard 4 is also formed of the same material as the flooring 3, and at both longitudinal ends of both baseboards 4,
The connection pieces 5 having the connection holes 5 a are respectively provided on the extension of the baseboard 4 to protrude.
