Construction reinforcing structure for high-space large-span section steel concrete structure beam hanging mold and construction method thereof

Abstract

The invention provides a construction reinforcing structure for a high-space large-span section steel concrete structure beam hanging mold and a construction method thereof. The construction reinforcing structure is characterized by comprising a prefabricated structural steel beam which is fixed on a construction site, a beam bottom die, a beam side template and a wooden square column which are preliminarily installed in-place, a plurality of hook head screws are welded and suspended at the bottom of the prefabricated steel beam lower flange plate, a gap inner template between the bottom of the hook head screws and the wooden square column on the bottom of the template, a longitudinal steel pipe and a fastener are used for fixedly suspending a U-shaped splicing channel steel, secondary reinforcement is carried out on the beam bottom die by utilizing a transverse steel pipe constructed by the beam bottom of the steel concrete structure beam, the two ends of the drawing rib are transversely and originally designed in the structure to conduct secondary reinforcement on the side die formworks on the two sides of the section steel concrete structural beam, and the purpose of reinforcingthe bottom die and the beam side die of the beam of the steel concrete structure is achieved. According to the construction method, the construction quality of the high-space large-span section steelconcrete structure beam hanging mold construction is improved, the engineering cost is reduced, and the safety of construction operation is ensured.

Description

technical field [0001] The invention belongs to the technical field of construction and reinforcement of concrete structures, and in particular relates to a construction and reinforcement structure of high-space and large-span steel concrete structure beams by hanging formwork and a construction method thereof. Background technique [0002] With the rapid development of the city, the high-space and long-span steel concrete structure has the advantages of good fire resistance, local and overall stability of the structure, good seismic performance of the structure, and saving steel. It is more and more used in urban public buildings, but this structure Generally, the storey height is high, the span is large, and the cross-sectional size of the beam is large. During the construction process, a high-support formwork support system is required, and the construction safety and difficulty are relatively high. [0003] The traditional steel concrete structural beam reinforcement con...
