Knuckle at；
5) described stair bench zigzag side form is hung to the steel pipe in the sizing steel pipe locating support using iron wire
On, complete formwork.
In abovementioned steps (1)：
The thickness of first, second plank sheathing is 15mm, and its length and width is layout design size.
The specification of first, second flitch is 50*80mm.
The round steel specification for making the Z-shaped reinforcing bar is φ 12.
In abovementioned steps (1), (2)：
Described steel pipe, supporting steel pipe, the specification of split bolt steel pipe are φ 48*3.5mm.
Instant invention overcomes the shortcoming that prior art is present, its advantage is；
(1) it make use of steel pipe locating support to install technology, install what is installed with typified form than traditional template, flitch
Method, is less prone to problem on deformation, beneficial to the guarantee of construction quality.
(2) fund input is saved, it is easy to installation, particularly the height of stair step and tread run quality
It is well controlled.
(3) solve the art is difficult to ensure that stair step quality in terms of stair formwork erecting all the time well
Construction difficult problem, with good practicality.
