Background technology
Concrete staircase is an important component of high building structure, and construction quality requirement is stringent.It is built at present
Stair formwork erecting in field mainly has two Class Types：One kind is to form support top by the connection between iron nail and template, flitch to step on
Walk formwork erection；Another kind of is to complete formwork using the assembling technique of the typified forms such as aluminum dipping form, punching block.
Although two class mold methods are widely used by building field more than, are had the following disadvantages when constructing：
(1) it forms support top by the connection between iron nail and template, flitch to mark time the method for formwork erection, iron nail is unique solid
Fixed, connector, and mould strip strength is little, the problem of easily deformation；
(2) using the assembling technique of the typified forms such as aluminum dipping form, punching block, once infusion of financial resources is too big while exigent
Mounting technique.
Utility model content
The purpose of this utility model is exactly to solve the problems of more than prior art, and provides one kind thus for controlling
Reinforced concrete stairs processed is marked time the erecting device of geometric dimension.
The technical solution of the utility model is：
A kind of erecting device for being used to that reinforced concrete stairs to be controlled to mark time geometric dimension, including stair step formwork erection, building
Bench zigzag side form and sizing steel pipe locating support；The stair step formwork erection is by being suitable for the width of stair step
It is formed with the first plank sheathing of height and the first flitch for being fixed on the upper and lower both sides of the first plank sheathing with iron nail respectively；Institute
The stair bench zigzag side form stated is by being suitable for ladder length and stair step profile height and being made the second of zigzag fashion
It plank sheathing and the second flitch of the two plank sheathings both sides is fixed on iron nail is respectively formed；The sizing steel pipe positioning branch
Frame includes the Z-shaped reinforcing bar for the width for the being suitable for stair step and height being processed into round steel, the Z-shaped reinforcing bar it is each
Vertex is welded on successively on same root steel pipe.
In aforementioned setting：
The thickness of first plank sheathing and the second plank sheathing is 15mm；
The sectional dimension of first flitch and the second flitch is 50x80mm；
Make a diameter of 12mm of round steel of the Z-shaped reinforcing bar；
A diameter of 48mm of the steel pipe, wall thickness 3.5mm.
The beneficial effects of the utility model are；
(1) steel pipe locating support is utilized and installs technology, installs what is installed with typified form compared with traditional template, flitch
Method is less prone to problem on deformation, conducive to the guarantee of construction quality.
(2) fund input is saved, is easily installed the height of construction, particularly 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 has good practicability.

Specific embodiment
In order to which the technical solution of the utility model is made to be easier to be understood, below in conjunction with the accompanying drawings with building in China Democratic National Construction Association engineering
The embodiment of terraced formwork construction is described in detail.
With reference to Fig. 1, Fig. 2, Fig. 3, the utility model is used for the formwork that reinforced concrete stairs is controlled to mark time geometric dimension dress
It puts, including stair step formwork erection, stair bench zigzag side form and sizing steel pipe locating support；
The stair step formwork erection 1 by be suitable for the width of stair step and the first plank sheathing 11 of height and respectively with
The first flitch that iron nail is fixed on the 11 upper and lower both sides of the first plank sheathing forms 12；
The stair bench zigzag side form 2 is by being suitable for ladder length and stair step profile height and sawtooth being made
It second plank sheathing 21 of shape and the second flitch 22 of 21 both sides of the second plank sheathing is fixed on iron nail is respectively formed；
The sizing steel pipe locating support 3 includes width and height that stair step is processed into and be suitable for round steel
Z-shaped reinforcing bar 31, each vertex of the Z-shaped reinforcing bar 31 are welded on successively on same root steel pipe 32.
With reference to Fig. 4, Fig. 5, it is using the method that the utility model carries out stair formwork erecting：
(1) using the concrete staircase that ground or lower floor have poured as supporting point, using diameter 48mm, wall thickness 3.5mm
