Conversion layer large-span section steel concrete beam and construction method thereof

Abstract

The invention provides a conversion layer large-span section steel concrete beam and a construction method thereof. A beam bottom steel bar shaping bracket comprises a non-dismantling shaping bracketand a dismantling shaping bracket, section steel beam peripheral steel bars bind the shaping brackets to be fixed on a scaffold, bolts and triangular reinforcing plates are arranged, and section steelbeam longitudinal steel bars and concrete column steel bars are in lap joint and bound through clamps with grooves; and a lifting jack drives section steel elevation adjusting crossbeams to perform preliminary fall of section steel and rough adjustment of the section steel elevation, the section steel elevation is further adjusted through fine adjustment bolts, a horizontal lifting jack is arranged to roughly adjust the section steel position, a horizontal alignment fine adjustment device is arranged to align, and accurate fall of the section steel is guaranteed. A beam side die is provided with a U-shaped clamp and a side wall adjustable shaping triangular support frame, and the die is jacked and retreated by the jack. According to the conversion layer large-span section steel concrete beam and the construction method thereof, the quick binding of the section steel beam steel bars, the quick lap joint and binding of the beam column steel bars, the accurate positioning of the sectionsteel and the reinforcement and shaping of the beam side die can be realized, and the construction efficiency of a section steel concrete beam is greatly improved.

Problems solved by technology

[0003] At present, in actual construction, it is difficult to bind the steel bars at the bottom of the beam and the steel bars around the beam. When the bottom steel bars of the steel beams are tied together, if the steel bars at the bottom of the beam are not well bound, it is easy to lose the steel bars in the concrete pouring and vibration projects. The position is not fixed and causes disorderly movement, and the position that may not meet the design requirements will seriously lose the bending resistance of the component

In addition, the positioning of section steel is also difficult to achieve the accuracy required by the corresponding design. Th
