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, and its feature existsIn: also comprise steel corbel, the main back cord of double flute steel, shaped steel time back cord, screw rod and nut; Described steel corbel is welded on section steel beam twoSide, the main back cord of double flute steel is connected and fixed by screw rod and nut and bracket, and shaped steel time back cord is laid on the main back cord of double flute steel to be usedCarry out support type steel concrete crossbeam.
Also comprise backing plate, described screw rod and the main back cord of double flute steel and bracket junction all arrange backing plate.
The construction method of Super High conversion layer steel reinforced concrete crossbeam suspension type form bracing system, is characterized in that comprisingFollowing steps:
(1) steel corbel and section steel beam welding, lift and set up crosshead by the section steel beam that is welded with steel corbel;
(2) mounting rail means for supporting reinforcement steel bar, mounting rail reinforcing bar;
(3) the main back cord of double flute steel is in place;
(4) place shaped steel time back cord;
(5) mounting rail end template, main double flute steel back cord and bracket are connected and fixed with screw rod.
Also be included in after 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 by main double flute steel back cord and bracket is connected and fixed and enclosed beam side template after carry out concreting.
Described beam steel bracing frame is welded on the top flange of section steel beam.
On the operating platform of described crosshead, all lay sheeting caps.
The present invention has following beneficial effect:
1. need not set up steel pipe support system at multiple floors, greatly reduced workload, and quick construction be protected effectivelyDemonstrate,prove construction speed.
2. can directly load be passed to vertical structure, with respect to traditional steel pipe support system, avoid beam slabIsostructural impact;
3. can effectively reduce turnover rack material lease expenses and labor cost, remarkable in economical benefits.
