<p>PURPOSE:To easily and surely fix a protecting pipe by arranging a number of anchor bolts in a concrete placing temporary frame buried in the ground, mutually connecting them by a connecting plate to form the insert part of the protecting pipe, and mounting a positioning member on the anchor bolts. CONSTITUTION:A rise fixing device is to fix a protecting pipe A in which each piping for lighting is collectively housed in the raised state from underground onto the ground. A number of anchor bolts 1 are arranged at prescribed intervals in a concrete placing temporary frame buried in the ground. Each anchor bolt 1 is mutually connected by a connecting plate 2 to form the insert part 4 of the protecting pipe A. Further, a rigid positioning plate 5 having mounting holes 7 to the anchor bolts 1 and the positioning part 8 of the protecting pipe A is mounted on the anchor bolts 1 to fix the protecting pipe A in a prescribed position. Thus, the rise of the protecting pipe A can be easily and surely fixed in the prescribed position.</p> |
