2) stair bench zigzag side form is made:
According to the length of bench and the profile height of stair step, zigzag fashion is made in the second plank sheathing of selection, and at it Iron nail fixes the second flitch respectively for both sides;
3) sizing steel pipe locating support is made:
According to the width and height of stair step, Z-shaped reinforcing bar is processed into round steel, and each summit is welded successively by it On same steel pipe;
(2) installation of staristep plate bed die:
1) concrete staircase poured using ground or lower floor is as the strong point, using supporting steel pipe to that will pour The staristep plate bed die of concrete staircase carries out support top, and ejects on the shear wall at stair the bullet of plate bed die installation site Line;
2) by the stair bench zigzag side form completed be arranged on bench side, and using staristep face short side to The split bolt in split bolt hole on the shear wall at place is inserted into split bolt steel pipe, the split bolt steel pipe it is another Stair bench zigzag side form is arrived in one end to top;
3) combine and ejected on the riser height of layout design, the shear wall in staristep with the high institute of each top mark marked time The straight line being linked to be, to position the position of stair step formwork erection 1, and by described stair step formwork erection and stair bench zigzag side The junction of mould is reinforced with iron nail;
4) described sizing steel pipe locating support is close to described stair step formwork erection and is stuck in described Z font reinforcing bars 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.
