Description
Technical field
The present invention relates to a kind of new builing structure technical field, be specifically related to the dark beam composite floor system of a kind of honeycomb steel.
Background technology
In Residential Building, large bay (being that every cover house is a big room) superstructure can form the space of flexible partition, becomes the optimised form that solves ornament intention and former design function contradiction.But traditional beam and slab structure superstructure modular system can't meet this flexible, various modern functions requirement.To this, there is the scholar to propose the superstructure forms such as the flat beam precast assemble floor of combination, hidden steel beam flat slab, the novel superstructure of self-bearing type.Regrettably, the superstructure of these forms has a common shortcoming: whole superstructure is heavier, and it is relatively poor to combine the globality of flat beam precast assemble floor, and anti-seismic performance is not good enough; And the steel bar girder procedure complexity of the novel superstructure of self-bearing type is time-consuming, and the easy spillage of back plate connections.The superstructure of these forms has only solved the indoor problem exposed without beam, and fails effectively to solve the structure height that reduces the large bay superstructure, effectively reduces the building floor height, reduces dead load and reduce the key issues such as Civil Cost.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of honeycomb steel dark beam composite floor system, Steel Castellated Beams is embedded among profiled sheet and reinforced concrete floor, solve dexterously stability, fire prevention and the Anticorrosion of the dark beam of steel, increase the interlayer headroom, alleviate dead load, effectively reduce the comprehensive cost of engineering.
The technical solution used in the present invention is: the dark beam composite floor system of a kind of honeycomb steel comprises reinforced concrete floor, reinforcing bar, the dark beam of steel, girder and profiled sheet; Described girder and steel column form framework, girder is embedded in party wall, dispose reinforcing bar in described reinforced concrete floor, be provided with profiled sheet below reinforced concrete floor, the dark beam of described steel vertically splices on girder, the top flange of the dark beam of steel and web are embedded in reinforced concrete floor, and intersect the part welding with the reinforcing bar in reinforced concrete floor, the trough of described profiled sheet is connected with the bottom flange of the dark beam of steel, the dark beam of described steel is the dark beam of cellular steel, offers a plurality of holes on the web of the dark beam of steel.
As preferably, the hole on the web of the dark beam of described steel is circular.
As preferably, the hole on the web of the dark beam of described steel is polygon.
As preferably, the bottom flange of the trough of described profiled sheet and the dark beam of steel adopts welding or self-drilling connection.
The dark beam composite floor system of honeycomb fashion steel of the present invention is a kind of space structures jointly be comprised of Steel Castellated Beams, reinforced concrete floor and profiled sheet.It is by being embedded in girder steel among profiled sheet and reinforced concrete floor, utilize adhesion stress between girder steel and concrete to realize the acting in conjunction of the two, utilize and firmly connect and compose reliable support framework between the dark beam of steel mesh reinforcement and steel, utilize profiled sheet to reduce the thickness of reckoning the actual amount after a discount of superstructure, to reach, reduce dead load and the purpose that reduces the engineering comprehensive cost.
Girder in the present invention is embedded in party wall, and according to structural entity, analysis designs, and the dark beam of steel and girder can splice.Because the dark beam of steel is embedded among concrete, and with the steel mesh reinforcement welding, so its monolithic stability and local stability all can be guaranteed, so get final product by Intensity Design.The trough of profiled sheet (bottom flange) welds or self-drilling connection with the bottom flange of the dark beam of steel, and profiled sheet should be depending on the different situations design of composite floor or non-composite floor.The steel mesh reinforcement that the reinforcing bar of the above configuration of the crest of profiled sheet (top flange) forms, with the dark beam of steel, intersecting the part welding, in order to jointly form reliable support framework.The configuration of reinforcing bar should be looked the different situations of composite floor or non-composite floor and designing and calculating is determined.Near the reinforcing bar of the configuration trough of profiled sheet (bottom flange), by structure requirement configuration.Concrete in the present invention and protective layer thickness thereof etc., press the conventional method of Design of Floors and determine.
Beneficial effect: superstructure of the present invention, form of structure is reasonable, and structural span is large, can meet the functional requirement of large bay superstructure, be conducive to the flexible arrangement in room and freely separate, the user can reconfigure usage space according to the indoor partition wall of the random dismounting of the wish of oneself, and is convenient to transformation.
The present invention can increase indoor headroom to greatest extent, reduces the structure floor height, has increased number of floor levels on identical depth of building, also the corresponding expense that reduces space enclosing structure, finishing and pipeline facility.
Girder steel of the present invention wraps in concrete, has greatly improved stability and the anticorrosion fireproof performance of girder steel.
Superstructure of the present invention, owing between steel mesh reinforcement and the dark beam of steel, firmly connecting and composing reliable support framework, and cast-in-situ concrete, so its integral rigidity is large, anti-seismic performance good, shock resistance is good.
Superstructure of the present invention, do not appear secondary beam, smooth at the bottom of plate, without furred ceiling.
The dark web of steel in superstructure of the present invention punches, and both can alleviate deadweight, is convenient to again the traversing pipe lines such as water power, optical cable and lays.
Superstructure of the present invention, easy construction is quick, greatly shortens construction period, reduces the engineering comprehensive cost.
Superstructure of the present invention, given full play to the stress performance advantage of Steel concrete and brought significant economic benefit.
