Described first floor concrete filled steel tube column bottom is the most extended an armored concrete suspension column, and armored concrete suspension column mixes with reinforcing bar Connected by suspension column backing plate and foundation bolt between solidifying earth foundation post.

Described steel core concrete column is square steel tube concrete column, and sectional dimension is 200mm × 200mm.

Described herringbone is supported for square steel tube or round steel pipe herringbone supports.Particularly, square steel tube herringbone supporting section is a size of 120mm×120mm。

Described H girder steel depth of section is 300mm~400mm.

It is welded with connection H girder steel and the connecting plate of independent component assembly unit on described sleeve, and on connecting plate, is 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 Layer, seismic fortification intensity is not more than 8 degree.

Injected hole and steam vent it is additionally provided with on described steel core concrete column.

The construction method of above-mentioned rural area assembling type steel structure dwelling house system, employing following steps:

Step one: prefabrication plane assembly unit, independent component assembly unit and stair assembly unit;At concrete filled steel tube Injected hole and steam vent are set on post, according to the position of H girder steel by sleeve weld to steel core concrete column, then H girder steel are welded Receive on sleeve;Independent component assembly unit arranges bolt hole;

Step 2: require location setting-out according to design drawing, excavates ground, arranges independence in bottom, steel core concrete column position Reinforced concrete foundation, 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 foundation bolt not less than 20mm;

Step 3: the armored concrete suspension column of extension is set in first floor concrete filled steel tube column bottom;

Step 4: when the concrete strength of reinforced concrete foundation and reinforced concrete foundation post all reaches more than 70%, installs The plane assembly unit of the first floor also surrounds the three-dimensional assembled unit constituting the first floor, by steel core concrete column and reinforced concrete foundation post By armored concrete suspension column one_to_one corresponding, and it is connected firmly by foundation bolt;

Step 5: be attached by independent component assembly unit between each three-dimensional assembled unit, three-dimensional assembled unit and independent structure Between part assembly unit with bolts by connecting plate and be aided with and be welded to connect;Stair assembly unit is three-dimensional assembled with described Unit and individually component assembly unit are connected;

Step 6: assemble each three-dimensional assembled unit of last layer plane, stair assembly unit and independent component assembly unit, up and down Connected by sleeve weld between layer steel core concrete column, complete the assembling of floor;

Step 7: cleaning concrete filled steel tube column wall, waters steel core concrete column inner concrete;

Step 8: install shingle nail, roof boarding and door and window;

Step 9: use light section steel structure triangular roof truss at top, it is supported on steel core concrete column.

Wherein, for post-disaster reconstruction engineering, because of very tight to construction period, do reinforced concrete foundation the most long, can be according to tool Body requires to make base steel plinth.Described base steel plinth can be by supporting steel plate, floor of putting more energy into, the basis component such as steel column composition, can allow the victims of the disaster First live in peace and move in, further according to requirement for anticorrosion, base steel plinth carried out corrosion-resistant concrete protective measure.

Described plane assembly unit, three-dimensional assembled unit and independent component assembly unit are considered as being easy to production and building site is installed and connected And transport, also to ensure livable being suitable for, standardization, modularization, seriation should be formed, applicable industrialization forms a complete production network requirement.

Beneficial effect:

Advantage of the invention is that the H girder steel composite construction using steel core concrete column and the support of band herringbone is as the load-bearing structure of house Part, this supporting member sectional dimension is less, and component can be completely hidden in fender body, it is ensured that the building of house uses requirement, Stress and deformation performance are preferable simultaneously.Filling concrete in steel pipe, the steel tube confinement deformation of concrete, delay pressurized cracking, In steel pipe, fill concrete avoids steel pipe pressurized generation cripling destruction simultaneously, and bi-material gives full play to respective advantage, makes The bearing power increase of component.Assembled by the assembled unit of prefabrication being carried out building site, eliminate reinforcing bar binding, building site coagulation The operations such as soil model sheetinstallat, construct more convenient.Its basis can use independent reinforced concrete under frame column as required Plinth or base steel plinth.

Owing to this assembled dwelling components uses prefabrication, on-site consolidation, component is easy to connect, quick construction, the most significantly Shorten construction period, saved the construction cost of peasant, it is provided that the living environment that high-strength light, anti-seismic performance are good, have The strongest sustainable developability.It is contemplated that, along with going deep into of China's economy, the development of technology and steel house research, inhale Take existing construction empirical studies and be suitable for the low-rise steel residential structure of rural condition, new rural village housing conditions is applied, special It not that post-disaster reconstruction will have significant economic benefit and social benefit.
