The pipe clamp 18 is a well-known conventional one, and includes a receiving metal 18a, a holding metal 18b that can be freely opened and closed, and a fastener 18c that fastens and fixes the free end of the holding metal 18b to the metal 18a.

[0012]

According to the temporary fence support device for construction of the present invention which can be implemented and used as described above,
Two fences adjacent by fence connecting means (1)
The vertical struts (7a, 7b) of (4) are connected to each other, and the lower end of the support rod (2) whose upper end is pivotally connected to the fence coupling means (1) by the left and right horizontal pivots (14). The each fence (4)
Vertical edge of the back of the section steel (5) on the ground supporting
The fences (4) can be held in a vertical posture by being coupled to the (5b) via the attaching means (3).

Therefore, a steel pipe for connecting the fences (4) to each other and a steel pipe for fixing the lower end of the supporting rod (2) are not required, and the fence connecting means (1) is connected to the fence (4). The mounting work also serves as the work of connecting the fences (4) to each other and the work of attaching the support rod (2) to each fence (4). Significant cost reduction of work can be achieved. In addition, since each fence (4) is held in a vertical posture by the support rod (2) on the vertical struts (7a, 7b) on both sides thereof, a strong temporary fence row can be formed. Further, according to the configuration of the present invention,
The lower end of the support rod (2) is fitted to the fitting (16) of the mounting means (3).
Directly supported by left and right horizontal support shafts (15)
Therefore, the fence temporary work can be performed more efficiently.

[0014] Incidentally, according to the configuration of claim 2, because it can freely adjust the effective length of the support rod (2), according to the height of the fence (4) to be used, the fence (4 ), The height at which the fence connecting means (1) is mounted can be adjusted, and a temporary fence row with higher safety can be easily formed.
