Be equipped with a plurality of square timbers 6 between square steel pipe 5 and the clear water template 7, the composite formwork structure is used for concrete placement shaping and bearing, and the structure is light, and it is convenient to be under construction. The sizes of the square steel tubes 5 and the square timbers 6, and the distance between the square steel tubes 5 and the distance between the square timbers 6 are determined by stress analysis.
The plastic sleeve head 4 has the effect of isolating the high-strength bolt 2 from the concrete, the high-strength bolt 2 is prevented from being bonded with the concrete to cause incapability of dismounting, and the nut 3 and the plastic sleeve head 4 are kept in the concrete when the formwork is dismounted and are not taken out any more.
The high-strength bolt 2 is an axial stressed member, so that the high-strength bolt can be prevented from bending deformation, and the characteristic of high tensile strength of the high-strength bolt 2 is effectively utilized.
After concrete pavement finishes, only need artifically demolish high strength bolt 2 and built-up plate structure, keep somewhere nut 3 and plastics pullover 4 in the concrete and can accomplish bridge floor concrete pavement work, need not secondary construction and repair, the template is demolishd the step and is simple, and the construction is high-efficient.
The thickness of the clear water template 7 is equal to that of the upper wing plate of the I-shaped steel beam 1
The utility model has the advantages that:
the utility model discloses a high-efficient I-steel-mix combination beam decking template structure and usage, high-efficient swift when concrete decking construction of mating formation, mainly embody following several points:
1. the high-strength bolt is an axial stress component, and is not easy to bend and deform, so that the high-strength bolt is convenient to disassemble and recycle.
2. The template structure installation is light, and the construction preface is simple, can demolish high strength bolt and built-up plate structure fast after concrete bridge deck pours and accomplishes, and need not the secondary and repair, therefore the construction is swift.
