Technical problem to be solved by this invention is achieved through the following technical solutions:
A kind of Super High conversion layer steel reinforced concrete crossbeam suspension type form bracing system comprises section steel beam, it is characterized in that: also comprise steel corbel, double flute steel master back cord, shaped steel time back cord, screw rod and nut; Described steel corbel is welded on the section steel beam both sides, and double flute steel master back cord is connected and fixed by screw rod and nut and bracket, and shaped steel time back cord is laid on and is used for support type steel concrete crossbeam on the double flute steel master back cord.
Also comprise backing plate, described screw rod and double flute steel master's back cord and bracket junction all arrange backing plate.
The job practices of Super High conversion layer steel reinforced concrete crossbeam suspension type form bracing system is characterized in that may further comprise the steps:
(1) steel corbel and section steel beam welding will be welded with the section steel beam lifting of steel corbel and set up handling frame;
(2) mounting rail means for supporting reinforcement steel bar, the mounting rail reinforcing bar;
(3) double flute steel master back cord is in place;
(4) place shaped steel time back cord;
(5) the mounting rail soffit formwork, with screw rod double flute steel master's back cord and bracket are connected and fixed.
After also being included in the mounting rail reinforcing bar, welded grider side Screw arbor with nut at both-ends, the then step of enclosed beam side template.
Until screw rod with double flute steel master's back cord and bracket is connected and fixed and the enclosed beam side template after carry out concreting.
Described beam steel bracing frame is welded on the top flange of section steel beam.
All lay sheeting caps on the operating platform of described handling frame.
The present invention has following beneficial effect:
1. need not set up the steel pipe support system at a plurality of floors, greatly reduce workload, and quick construction has guaranteed construction speed effectively.
2. can be directly with Load Transfer to vertical structure, with respect to traditional steel pipe support system, avoided the isostructural impact of beam slab;
3. can effectively reduce turnover rack material lease expenses and labor cost, remarkable in economical benefits.
