Description of the Related Art In the steel pipe erection of a suspension bridge type pipe bridge, for example, Japanese Utility Model Publication No. 39-1178 discloses a support device in which a erection roller is attached to a support ring. FIG. 5 shows an example of mounting such a prior art support ring and an installation transport roller.
(Side view) and FIG. 6 (front view). The roller frame 10 of the transport roller 3 has the mounting portion 11 bolted to the support ring 2 by bolt-nut joints 12 and 13, and is sandwiched between the steel pipe 1 and the support ring 2. For this reason, when removing the transport roller 3, it is necessary to suspend the steel pipe 1 separately or suspend the support ring 2. In any case, an extra load acts on the hanging rope 7, which is not preferable. Also, when removing the transport roller 3, it is necessary to insert a hand into the gap between the transport roller 3 and the steel pipe 1, and there is a risk of pinching the hand. In addition, it takes time to remove.

２、連結手段５、搬送ローラ３を示したものである。FIG. 1 shows a side view of an embodiment of the method of the present invention. A support ring 2 suspended by a suspension rope 7,
Are attached to the temporary connection means 5 with the hinge connection tool 4. The temporary fastening connecting means 5 may be a simple frame, for example, a long frame in which a pair of right and left shaped steel members or the like are appropriately connected by a horizontal connecting member, and the hinge connecting tool 4 is provided at a support ring position. By the connecting means 5, the distance between the support rings can be kept constant. FIG. 4 shows an example of the hinge connector 4. The connecting means 5 is connected to a hinge connecting tool 4 supported in the ring 2 by a bolt and nut 8. Since the temporary fixing connection means 5 are hingedly connected to each other, even if the support ring 2 is vertically displaced, it is possible to cope with the displacement. The hinge connector 4 and the support ring 2 are connected by bolts and nuts 8 so that attachment and removal are easy. The temporary fixing connecting means 5 also serves as a transport roller support member, and has the transport roller 3 mounted at an intermediate position between adjacent support rings. The steel pipe 1 is pulled on the conveying roller 3 in the feeding direction 6 and moves in the support ring 2. FIG. 2 is a front view of FIG. 1 and shows a state in which the steel pipe 1 travels on the transport roller 3 through the inside of the support ring 2. FIG. 3 is a plan view showing the support ring 2, the connecting means 5, and the transport roller 3 without steel pipe.

In comparison, attachment and removal together with the connecting means 5 can be performed very easily. As described above, according to the present invention, by temporarily fixing the support rings 2 and 2 with the connecting means 5 and installing the transport roller 3 between the support rings 2 and 2, it is not necessary to correct the interval between the support rings 2 and 2. In addition, the workability at the time of removing the transport roller 3 can be significantly improved.
