Abstract

The invention relates to a construction method of a complex steel-concrete composite structure, comprising steps: step 1, adopting a complex steel-concrete column-slab structure to construct steel-concrete slab-column joints; step 2, adopting a complex steel-concrete steel-column splicing structure to splice steel columns Node construction; Step 3, adopting complex steel-concrete-steel-column-beam-column structure for steel-concrete beam-column node construction; Step 4, complex steel-concrete composite structure reinforcement binding and pouring. The invention has the beneficial effects of: effectively strengthening the connection performance of the upper and lower steel columns, speeding up the construction efficiency, and preventing concrete voids at the joints; forming a stable whole by bolting high-strength bolts at the stiffeners, effectively improving the shock resistance of the assembled joints of the steel columns; The stability of the beam-column joint is enhanced; the workload of positioning the upper and lower steel columns at the steel-concrete beam-column joint is greatly reduced, and the connection performance of the steel-concrete beam-column is enhanced.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a complex steel-concrete composite structure and a construction method. Background technique [0002] In the construction process of conventional steel-concrete composite structures, welded ear plates on the flanges of steel columns are often used for positioning and fixing, and the embedded parts at the column caps are L-shaped embedded parts, resulting in poor seismic performance at each node of the steel columns. Construction measures have to be taken during construction to meet the seismic performance of each node, such as welding reinforcements, increasing the number of bolts used, etc. When encountering a project with a tight construction schedule and high seismic resistance, the conventional steel-concrete composite structure construction technology cannot meet the requirements. [0003] In the limited construction period, in order to ensure the seismic perf...
