Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a socket flange connection cylinder type independent fast disassembly formwork support. BACKGROUND

[0002] At present, large-span beam-slab structures greater than 8m are common in frame structure construction, and formwork support is essential in the construction process of large-span beam-slab. The removal of formwork support after beam-slab pouring is strictly required in the construction specification, and the concrete strength must be equal to 100% of the design standard value of the concrete cube compressive strength before the formwork support can be removed; however, in most regions of China, the average temperature of day and night in summer can only reach about 21.5 degrees Celsius, and it takes 28 days to meet the requirements for removing the formwork, and it takes longer when the temperature is lower than 21.5 degrees Celsius, that is, at least 28 days are needed after pouring to remove the formwork support, which has a long waiting period and low turnover utilization rate of formwork support.

[0003] To this end, the related art adds independent formwork support to reduce the span of the beam-slab and shorten the removal period of the formwork support, for example, for an 8m beam-slab structure, an independent formwork support can be added at the middle position to divide it into two 4m beam-slab structures, and the formwork support of the 4m beam-slab structure can be removed when the concrete strength reaches 75% of the design standard value of the concrete cube compressive strength, which only takes 12 days to reach the compressive strength under an average temperature of 15 degrees Celsius, greatly reducing the removal period of the formwork support; however, in the related art, when the independent formwork support is added, for the position of the structural column set at the beam bottom, since many structural column reinforcing bars need to be set, the existing independent formwork support cannot be set at this position, and the construction can only avoid this position, which brings inconvenience to the construction.
