Described vertically little curved round steel pipe is by the continued access of joint card, and the extended line of vertical little curved round steel pipe axis of continued access overlaps.
Every cross binding steel pipe is separately positioned on cross binding steel pipe centre position and 2.5m place, both sides, center by three vertical joint steel pipe support tops.
Described vertically little curved round steel pipe with the abut contact position, its end arranges the support collet and supports.
The setting space of described sealing steel pipe equates with the setting space of supported rod erecting.
Compared with prior art the utlity model has following characteristics and beneficial effect:
The utility model can solve the difficult problem at oblique angle between collet and main joist by using cross binding steel pipe, vertical little curved round steel pipe to replace traditional lumps of wood in conjunction with the mode of cross clip, can save the appurtenance expense that increases in construction; Steel pipe plasticity is higher, can little curved rear solution arch ring bottom radian require and concreting after a concrete surface planeness difficult problem, and after finishing using, can the scene do straightening and process, cost is saved in recycling.
The utility model is when the solution Arch Bridge Ribs causes mould bases to set up difficult problem due to camber line, and construction technology is simple, material can repeatedly have enough to meet the need.
The utility model can be widely used in the lower floor support of the larger Arch Bridge Ribs structure of ratio of rise to span.
