After the completion of work, the steel pipe for placing horizontal hack lever is welded on frame body according to design drawing horizontal distribution bar spacing, according to web
Oblique angle penetrates horizontal hack lever in steel pipe, completes standard frame and makes.
2) fixed standard frame：According to the good bottom web reinforcement groove of marking on prefabricated case beam pedestal, with 1m between left and right away from solid
Calibrate quasi- frame；
3) steel bar stress is installed：Bottom web stress reinforcing bar is installed according to the position marked, and is bound temporarily with standard frame,
Ensure that principal rod and standard frame are stablized；
4) rely on standard frame horizontal hack lever that horizontal distribution reinforcing bar is installed；
5) it checks adjustment reinforcement installation situation, completes the installation of bottom web reinforcement；
6) standard frame moves to next prefabricated case beam pedestal.
Further, step 1) Plays frame bottom is additionally provided with standard frame pedestal, and pedestal is made of 5-8mm steel plates.
Further, step 2) fixed standard frame frame body, you can be connected and fixed, can also be adopted using reinforcing bar and horizontal hack lever
The standard frame spot welding for determining riding position is stablized on prefabricated case beam pedestal with the mode of spot welding.
Further, the spacing of step 2) standard frame is disposed with the integral multiple of steel bar stress spacing.
Compared with prior art, beneficial effects of the present invention are：
Under the premise of ensuring construction quality, construction is greatly shortened using the method installation prefabricated case beam reinforcing bar of the present invention
Duration has saved labour cost, improves the installation quality of prefabricated case beam reinforcing bar, has good economic and social benefit.

Specific implementation mode
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, it should be understood that preferred reality described herein
Apply example only for the purpose of illustrating and explaining the present invention and is not intended to limit the present invention.
Embodiment 1
Before construction, standard frame is first made.As shown in Figure 1, standard frame is by the horizontal hack lever 1 of standard frame, 2 and of standard frame frame body
Standard frame pedestal 3 forms.
According to horizontal distribution bar spacing processing criterion frame in design drawing.2 main material of standard frame frame body can be used and use angle steel
It makes, frame body can be met and do not occured bending and deformation；The horizontal hack lever 1 of standard frame is made of 10~Ф of Ф, 12 round steel.Frame body makes
After the completion, 20 steel pipes of Ф are welded on frame body according to horizontal distribution bar spacing on design drawing, facilitate horizontal hack lever reinforcing bar energy
It penetrates.Installation steel pipe is that the length that is put in for horizontal 1 reinforcing bar of hack lever of standard frame is adjustable, can meet all types of precast box joist steels
Muscle is installed and used, cost-effective.Standard frame pedestal 3 is made of 5~10mm steel plates, and plate size, which should not be too large, can make standard
Frame frame body is firm to be placed.
Embodiment 2
Such as Fig. 2, shown in Fig. 3, when prefabricated case beam reinforcing bar being installed using the standard frame in embodiment 1, it is as follows：
1) it is required according to design drawing, determines prefabricated case beam web gradient, standard frame frame body 2 is made using angle steel；Frame body
After completing, the steel pipe of the horizontal hack lever of placement standard frame 1 is welded on frame body according to design drawing horizontal distribution bar spacing,
Horizontal hack lever is penetrated in steel pipe according to web oblique angle, is completed standard frame and is made.
2) fixed standard frame：According to the good bottom web reinforcement groove of marking on prefabricated case beam pedestal 4, with 1m between left and right away from solid
Calibrate quasi- frame.
The spacing of standard frame is disposed with the integral multiple of steel bar stress spacing, can effectively control steel bar stress binding spacing, mark
The horizontal hack lever of quasi- frame 1 can also play the role of horizontal distribution reinforcing bar rest, and horizontal distribution reinforcing bar can be placed on standard frame water
It is directly bound on flatrack bar, the process that binding horizontal distribution reinforcing bar is fixed temporarily both has been omitted, it is thus also avoided that horizontal distribution reinforcing bar
There is buckling phenomenon.
When fixed standard frame frame body, you can it is connected and fixed using reinforcing bar and horizontal hack lever 1, it can also be by the way of spot welding
The standard frame spot welding for determining riding position is stablized on prefabricated case beam pedestal 4.
3) steel bar stress is installed：Bottom web stress reinforcing bar is installed according to the position marked, and is bound temporarily with standard frame,
Ensure that principal rod and standard frame are stablized.
4) rely on standard frame horizontal hack lever 1 that horizontal distribution reinforcing bar is installed.
5) it checks adjustment reinforcement installation situation, completes the installation of bottom web reinforcement.
6) standard frame moves to next prefabricated case beam pedestal 4.
In conjunction with the above embodiments, the installation of bottom web reinforcement is carried out by the way of standard frame, effectively increases reinforcing bar
Bottom web reinforcement installation effectiveness, also solves the problems, such as horizontal distribution bar bending；It is improved using standard frame prefabricated case beam reinforcing bar
Bottom web reinforcement installation quality accelerates construction speed, reduces recruitment, reduces construction cost.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
Understanding without departing from the principles and spirit of the present invention can carry out these embodiments a variety of variations, modification, replace
