The invention provides a large-section prestressed frame beam formwork support system and a construction method. The opening support is arranged between the opposite opening plates; when the frame beam support system is erected, two column side hoop plates are arranged on the outer side of the bearing column along the ring direction. Set transverse braces and sliding braces on the outer sides of the column side hoops on the upper and lower floors respectively; set beam base forms on the load-bearing platform, and set steel bar position control bodies on the beam base forms; adjust the pressure plate adjustment bolts to make the combination After the connecting step of the type pressure plate is connected with the beam side formwork, a fastening screw is set between the connection bolts of the pressure plate; the formwork is supported and reinforced through the horizontal pressure bar and the vertical pressure bar; when the frame beam is maintained and constructed, the position control baffle The top is connected with the sliding maintenance device, and a downpipe is arranged between the sliding maintenance device and the water storage tank. The invention can improve the construction quality of concrete pouring and maintenance, improve the mechanical performance of the construction structure, reduce the difficulty of template support and positioning, and protect the construction environment.
Description
technical field [0001] The invention relates to the field of construction engineering, in particular to a large-section prestressed frame beam support formwork system and a construction method that can improve the mechanical performance of construction structures, reduce the difficulty of formwork support and positioning, and protect the construction environment, and is suitable for large-section prestressed beams. Frame beam construction works. Background technique [0002] With the steady and rapid development of my country's national economy, concrete structures are gradually developing in the direction of large spans and high heights, and a large number of large cross-section frame beam-column structures have emerged. Compared with the conventional concrete beam-column structure, it is characterized by large cross-sectional dimensions, high load-bearing requirements for the formwork system, and difficult control of concrete pouring construction, etc. [0003] In the pri...
