Abstract

The present invention proposes a kind of assembled stealth beam floor, belongs to building element field.Stealthy beam floor is the integral module formed by web beam with holes and reinforced concrete floor, and first using the beam being prefabricated in the factory as the frame of beam slab integral module, precast concrete is poured in beam bottom portion.Then above concrete layer can free pipeline installation, pipeline is passed through from soffit of girder plate holes between different plates, and lightweight concrete is poured after the completion of being laid with.Stealthy beam floor under the premise of not reducing bearing capacity, reduces the integral thickness of beam slab, improves building headroom, keep space layout more flexible by beam slab integration;The upper lower flange of beam is embedded in the concrete of floor, the concrete reserved around one side beam can improve the local stability of component, on the other hand alleviate fire prevention and the Anticorrosion of steel structure girder to a certain extent;The mode that web opens up hole and placement layer by layer floor is conducive to the personalized arrangement of pipeline, facilitates the repair and transformation in later stage.

Description

A kind of assembled stealth beam floor
Technical field
The present invention designs a kind of assembled stealth beam floor, belongs to building element field.
Background technology
Annual 20 billion cubic meter of town and country newly constructed house area in China, wherein 80% or more builds for high energy consumption, China's unit Construction area energy consumption is the 2 times or more of developed country.Meter is joined in a common effort according to Chinese steel, China's output of steel in 2011 is broken through 700,000,000 tons big Close, it is the first to be sure to occupy within continuous 16 years countries in the world output of steel, corresponding current domestic construction industrialization degree less than 10%, and Developed country's steel building area accounts for 50% or more overall floorage, and Japan accounts for 80%.China is as building rule in the world Mould, the maximum country of steel yield, the development of light-duty steel construction house seriously lag.
Although existing steel building improves speed of application to a certain extent, difficulty of construction is alleviated, still So there are problems.In the construction process, some uses composite floor with profiled steel sheet, removes a large amount of templates from, but profiled sheet increases Add cost, and finishing processing is inconvenient below floor, additionally needs arrangement temporary support;Some is using reinforced concrete sandwich building Plate is generally also required to arrangement temporary support, and preformed layer is thicker increases floor total height.Traditional contignation, plate are arranged in Liang Shang increases beam slab total height, reduces structure and uses height.Girder steel is exposed to need anti-corrosion fire prevention to handle, and increases cost, and steel The exposed flexible arrangement for being unfavorable for space of beam.Conventional floors fulgurite is embedded in structure sheaf, and building storey is poured on structure sheaf, and water warms up Equal pipelines are embedded in building storey, keep total floor thickness larger.
Invention content
The present invention proposes a kind of assembled stealth beam floor, and the purpose is to solve in background technology to a certain extent The problem of.Stealthy beam floor reduces the integral thickness of beam slab by beam slab integration under the premise of not reducing bearing capacity, Building headroom is improved, beam is hidden in floor, keeps space layout more flexible;The upper lower flange of beam is embedded in In the concrete of floor, the concrete reserved around one side beam can improve the local stability of component, avoid local buckling, On the other hand fire prevention and the Anticorrosion of steel structure girder are alleviated to a certain extent.Web opens up hole and layering is poured The mode of build floor is conducive to personalized arrangement and the installation of pipeline, facilitates the repair and transformation in invention later stage.
Technical solution of the present invention is as follows:
The assembled stealth beam floor is the integral module formed by the beam and reinforced concrete floor of holes in soffit. Using the beam being prefabricated in the factory as the frame of beam slab module, arranges reinforcing bar in girder steel lower position, poured in reinforcement location high Degree is the precast concrete of 40mm -100mm, forms reinforced concrete floor.Stealthy beam floor includes concrete (1), girder I (2), girder II (3), girder III (4), girder IV (5), middle part secondary beam I (6) and reinforcing bar.Girder I (2), girder II (3), girder III (4), girder IV (5) are located at reinforced concrete floor surrounding, and welding two-by-two is spliced into the frame of reinforced concrete floor, main Beam I (2) is parallel with girder II (3), is long side;Girder III (4) is parallel with girder IV (5), is short side;Middle part secondary beam I (6) cloth It is placed in the span centre position of reinforced concrete floor and is parallel to short side;The girder I (2), girder II (3), girder III (4), master Beam IV (5) and middle part secondary beam I (6) open up hole at web, the laying so as to pipeline and arrangement;Then in factory's frame Pouring for concrete is carried out, the prefabrication part of assembled stealth beam floor is eventually formed;Assembled stealth beam floor is transported It is sent to construction site, at the construction field (site), assembled in situ is carried out using lifting, on the concrete layer of stealthy beam floor Pipeline installation (water, warm, fulgurite etc.), pipeline is pierced by from soffit of girder plate holes, and pipeline is arranged between facilitating plate;Wait for that pipeline arranges Finish, lightweight concrete is poured up to top surface of the beam in concrete floor.After pour lightweight concrete layer using air entrained concrete, polyphenyl Particle concrete or haydite concrete, it is convenient to dismount and repair in the future pipeline.
Advantageous effect
The present invention proposes a kind of assembled stealth beam floor belonging to building element field, and it is pre- to overcome traditional architecture The more complicated construction technology of floor processed.Stealthy beam floor is reduced by beam slab integration under the premise of not reducing bearing capacity The integral thickness of beam slab, improves building headroom, and beam is hidden in floor, keeps space layout more flexible;By beam Upper lower flange is embedded in the concrete of floor, and the part that the concrete reserved around one side beam can improve component is steady It is fixed, local buckling is avoided, on the other hand alleviates fire prevention and the Anticorrosion of steel structure girder to a certain extent.Web is opened The mode of apertured hole and placement layer by layer floor is conducive to personalized arrangement and the installation of pipeline, facilitates the repair in invention later stage And transformation.
