Profile steel framework structure concrete floor slab suspension mould pouring construction method

Abstract

The invention relates to a profile steel framework structure concrete floor slab suspension mould pouring construction method. The profile steel framework structure concrete floor slab suspension mould pouring construction method comprises the steps of installing and correcting profile steel components, measuring a released line, designing and manufacturing a suspension mould system, manufacturing and installing a hoisting bar, installing main rods, installing secondary rods, laying formwork panels, tying floor slab steel bars, pouring and maintaining concrete, and detaching the suspension mould system. Compared with the prior art, the profile steel framework structure concrete floor slab suspension mould pouring construction method has the advantages of being high in construction speed, being stable in quality of a concrete structure, reducing the use of circulation materials, relieving vertical conveying pressure, improving labor efficiency and relieving labor intensity. Compared with a traditional steel pipe whole-building supporting frame, the profile steel framework structure concrete floor slab suspension mould pouring construction method improves the labor efficiency by about 2.5 times. Due to the fact that labor intensity is largely relieved, the work of operators is continuous.

Description

technical field [0001] The invention relates to a construction method, in particular to a construction method for hanging formwork pouring of a steel frame structure concrete floor. Background technique [0002] At present, the structural form of high-rise and super high-rise buildings in my country is mostly reinforced concrete core cylinder plus steel structure outer frame cast-in-place concrete floor. The core cylinder concrete structure generally adopts the technically more mature climbing formwork construction, while the support system of the outer frame floor of the steel structure is mostly used in two ways, one is the traditional steel pipe full frame plus wooden square plus formwork as the support system The advantage of this method is that it is safe and reliable, but the disadvantage is that the construction progress is slow, the labor intensity of the operator is high, and the cost is high; the other is a profiled steel plate or steel truss floor deck system. The...

The core cylinder concrete structure generally adopts the technically more mature climbing formwork construction, while the support system of the outer frame floor of the steel structure is mostly used in two ways, one is the traditional steel pipe full frame plus wooden square plus formwork as the support system The advantage of this method is that it is safe and reliable, but the disadvantage is that the construction progress is slow, the labor intensity of the operator is high, and the cost is high; the other is a profiled steel plate or steel truss floor deck system. The advantages of this construction method are that the construction is convenient and the quality is high. Stable, the disadvantage is that the cost is higher
