Described first floor concrete filled steel tube column bottom is also extended and is provided with a steel concrete suspension column, between steel concrete suspension column and reinforced concrete foundation post, by suspension column backing plate and stone bolt, is connected.
Described steel core concrete column is square steel tube concrete column, and sectional dimension is 200mm * 200mm.
Described herringbone is supported for square steel pipe or round steel pipe herringbone supports.Particularly, square steel pipe herringbone supporting section is of a size of 120mm * 120mm.
Described H girder steel depth of section is 300mm～400mm.
On described sleeve, be welded with the junction plate that connects H girder steel and independent component assembly unit, and on junction plate, be provided with bolt hole.
The floor height of described dwelling house system is 2.8m～3m, and depth is 5.1m～5.4m, and the standard width of a room in an old-style house is 3.6m～4.2m, and the number of plies is 2～4 layers, and seismic fortification intensity is not more than 8 degree.
On described steel core concrete column, be also provided with injected hole and steam vent.
The construction method of above-mentioned rural area assembling type steel structure dwelling house system, adopts following steps:
Step 1: the assembled unit of prefabrication plane, independent component assembly unit and the assembled unit of stair; Injected hole and steam vent are set on steel core concrete column, according to the position of H girder steel, sleeve are welded on steel core concrete column, then H girder steel is welded on sleeve; On component assembly unit, bolt hole is being set separately;
Step 2: require location setting-out according to design drawing, at bottom, steel core concrete column position excavation ground, independently reinforced concrete foundation is set, at reinforced concrete foundation construction reinforced bar concrete foundation post, and in reinforced concrete foundation column top pre-buried suspension column backing plate and the stone bolt that is not less than 20mm;
Step 3: the steel concrete suspension column that extension is set in first floor concrete filled steel tube column bottom;
Step 4: all reach 70% when above until the concrete strength of reinforced concrete foundation and reinforced concrete foundation post, the assembled unit of plane of the first floor is installed and is surrounded the assembled unit of solid that forms the first floor, steel core concrete column is corresponding one by one by steel concrete suspension column with reinforced concrete foundation post, and be connected firmly by stone bolt;
Step 5: connect three-dimensional assembled unit and separately with bolts and be aided with and be welded to connect by junction plate between component assembly unit between each three-dimensional assembled unit by independent component assembly unit; The assembled unit of stair is connected with the assembled unit of described solid and independent component assembly unit;
Step 6: assembling each three-dimensional assembled unit of last layer plane, the assembled unit of stair and independent component assembly unit, between levels steel core concrete column, by sleeve, be welded to connect, complete the assembling of floor;
