Background technology
Stair step in general shear wall structure building has two kinds of forms, and a kind of is that side of marking time has the building of shear wall
Ladder, another kind are the stair for having shear wall in both sides of marking time；The process that performs for having the stair step of shear wall to both sides is：
On the stair that lower first floor ladder concrete strength reaches after installing upper strata frame body requirement, the stair template branch of last layer is set up
Frame, then installs the bottom plate of this floor ladder, binds stair reinforcing bar, and according to absolute altitude and size of marking time, even partition stair are stepped on
Step, independently installs template of marking time, and a steel pipe is crimped in the upper end for template of respectively marking time, and consolidated with steel pipe with the silk template that will mark time is tied up
It is scheduled on together, marks time during casting concrete bulge phenomenon occur in order to prevent, is carried out in the lower end of template with the lumps of wood
Apical grafting is fixed, and finally carries out concreting, and it is that substep carries out that the template of this construction method, which is set up, the time length set up,
Be especially in the presence of stair tread formwork can not fixation the defects of, bulge phenomenon often occurs in casting process, due to
The support of whole formwork erection system is by two steel pipe banding fixeds set along stair direction, two in casting process
Steel pipe is easily distorted dislocation, be easy to cause the stair step torsional deformation poured.
