Problems solved by technology
The construction mode of reinforced concrete columns mainly adopts traditional on-site pouring construction, which is difficult to carry out industrialized large-scale production and has a long construction period. This construction mode has problems such as high energy consumption, high pollution, low efficiency, and extensive construction. , Incompatible with the requirements of information technology development
Concrete-filled steel pipe columns can be assembled by bolts or welding, but it is difficult to carry out factory production. Due to the increase in steel consumption, the construction cost is high, and the anti-corrosion and fire protection of steel pipes requires technical treatment. Dense resulting in local bending of the column
Steel concrete columns solve the problem of anti-corrosion and fire prevention of steel by outsourcing concrete, but pouring outsourcing concrete is more difficult, the amount of steel used is higher than that of reinforced concrete columns, and the connection with concrete beams is more complicated

Embodiment
[0044] The layout of the assembled steel-concrete combined column in this embodiment is as follows Figure 1(a) , 1(b)and 2 are shown. The steel-concrete combined column is 3 to 4 meters long, and the size of the column is 400mm×400mm. It is composed of concrete column 1, steel-concrete combination section 2 and short steel column 3. The length of steel-concrete combination section 2 is 250mm, height is 400mm, and width is 400mm; short steel column 3 is composed of H-shaped steel 8, stiffener 9 and connecting plate 10, the thickness of the flange and web of H-beam 8 is calculated according to the corresponding specifications,
[0045] The concrete column 1 and the steel-concrete combination section 2 of the present embodiment are as Figure 3-4 As shown, a certain number of longitudinal steel bars 5 are arranged in the concrete column 1, and the reinforcement ratio is calculated according to the actual engineering, and the stirrups are intensified at the steel-concrete junc...

The invention discloses an assembly type steel-concrete composite combined column structure, and a construction method thereof. The assembly type steel-concrete composite combined column structure comprises a concrete column, a steel-concrete composite segment, and a short steel column; the concrete column is composed of concrete, steel bar, a drilling device, and fining twisted steel bar; the short steel column is composed of fashioned iron, stiffening rib, and a connection plate; the steel-concrete composite segment is composed of shear connectors, concrete, stiffening rib, an anchorage system, steel bar, an end plate, an upper steel flange plate, and a lower steel flange plate; connection of concrete with the steel flanges of the steel-concrete composite segment is realized the shear connectors, so that co-bearing of external force is realized; the stiffening ribs are used for arranging the connection plate at the end part of the short steel column so as to increase the stability of the short steel column. According to the construction method, the advantages of concrete column and the advantages of steel column are combined, and steel and concrete are connected via the steel-concrete composite segment, so that full utilization of the excellent performance of the two materials is realized, mechanical property and construction operation performance of column structures are improved, rapid assembling construction can be adopted in construction of the assembly type steel-concrete composite combined column structure, construction speed is accelerated, construction period is shortened, and great economic benefit is achieved.
Description
technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to an assembled steel-concrete combined column structure and an implementation method thereof. Background technique [0002] In the current construction projects, the structural forms of columns mainly include: reinforced concrete columns, steel pipe concrete columns and steel concrete columns. The construction mode of reinforced concrete columns mainly adopts traditional on-site pouring construction, which is difficult to carry out industrialized large-scale production and has a long construction period. This construction mode has problems such as high energy consumption, high pollution, low efficiency, and extensive construction. , Information technology development requirements do not meet. Concrete-filled steel pipe columns can be assembled by bolts or welding, but it is difficult to carry out factory production. Due to the increase in steel consump...
