Description
Technical field
The present invention relates to building element technical field more particularly to a kind of prefabricated package Honeycomb Beams of holes in soffit.
Background technique
Annual 20 billion cubic meter of town and country newly constructed house area in China, wherein 80% the above are high energy consumption building, China's units
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 reaches 800,000,000 tons within 2016, from
The first in the world is sure to occupy from 2000, corresponding current domestic construction industrialization degree is less than 10%, and developed country's steel construction
Construction area accounts for 50% or more overall floorage, and Japan accounts for 80%.China is maximum as construction scope in the world, steel yield
Country, the development of light-duty steel construction house seriously lags.
China's building mostly uses traditional cast-in-place construction mode using combination beam floor now, and the girder steel below floor is
Steel flanged beam if holes in soffit is needed further to consider its destabilization problems, and girder steel easy-to-rust, non-refractory, is prevented from great
The problems such as corruption, fire prevention, is particularly important；Girder steel needs peg to be connected with each other with floor, and pouring concrete in-situ floor needs a large amount of moulds
Plate, labor intensive, material resources；Pipeline used is built mostly in the lower section of beam slab, causes to build headroom reduction, is occupied indoor using empty
Between；Under by load situations such as earthquakes, floor is controlling sections at support, bears hogging moment, and armored concrete is in tension
State is easily destroyed；In addition, beam slab section is T shape, deck-molding is the sum of girder steel height h0 and slab thickness L, girder steel free height
H0 cannot function as deck-molding expression, and statement is easily obscured.
Summary of the invention
Aiming at the shortcomings existing in the above problems, the present invention provides a kind of prefabricated package Honeycomb Beam of holes in soffit.
The invention discloses a kind of prefabricated package Honeycomb Beam of holes in soffit, including the molding steel skeleton of prefabrication and
Concrete layer；
The steel skeleton is " day " the font skeleton being made of four girders and a secondary beam, the girder and secondary beam
Web top is equipped with the hole passed through for pipeline；
The concrete layer wraps up the lower flange of the girder and secondary beam and the part web below described hole.
As a further improvement of the present invention, when construction, the prefabricated package Honeycomb Beam is transported to construction site, is used
The mode of lifting carries out assembled in situ；It is taken on the concrete layer of parallel girder and secondary beam and bleeds off pressure shape steel plate, with described
Profiled sheet is platform, passes through described hole and lays pipeline；After the completion of line layout, cast-in-place concrete forms and wraps up the pressure
Shape steel plate, pipeline, the top flange of the girder and secondary beam and remainder web cast-in-place concrete layer.
As a further improvement of the present invention, using the profiled sheet as platform, longitudinal reinforcement is laid；
The longitudinal reinforcement includes top longitudinal reinforcement and lower part longitudinal reinforcement, and the lower part longitudinal reinforcement passes through the master
Described hole on beam and secondary beam, the top longitudinal reinforcement passes through from the top flange top of the girder and secondary beam, described existing
Pouring concrete layer wraps up the top longitudinal reinforcement and lower part longitudinal reinforcement.
As a further improvement of the present invention, the prefabricated package Honeycomb Beam, profiled sheet, pipeline, longitudinal reinforcement and existing
Pouring concrete layer is overall structure.
As a further improvement of the present invention, the hole on the girder and the secondary beam is rounded.
As a further improvement of the present invention, the hole on the girder and the secondary beam is in rectangle.
As a further improvement of the present invention, with welding between the girder and girder, between the girder and secondary beam
Mode be connected and fixed.
Compared with prior art, the invention has the benefit that
The present invention cuts girder steel (girder or secondary beam) web, forms multiple rectangles or circular hole, not only mitigates self weight,
And pipeline used in building (water, warm, fulgurite etc.) can be passed through from hole, given up the traditional approach for walking pipeline in furred ceiling, accomplished
Pipeline is not exposed, achievees the effect that indoor regular beauty, and increase clear height inside room, to increase use space；
The present invention at the scene pouring reinforcement concrete floor when, profiled sheet is taken and is placed on adjacent concrete layer
On, stringing pricks placing concrete after muscle, is not necessarily to formwork, forms cast-in-place concrete layer；After the completion of construction, steel skeleton is by coagulation
Soil is fully wrapped around to improve the local stability of component in inside, and has good anti-corrosion, flameproof effect；
Conventional composite beam floor beam section is calculated by T shape, and deck-molding is the sum of girder steel height h0 and slab thickness L；Therewith not
With prefabricated package Honeycomb Beam of the invention is beam slab integral module, and deck-molding is girder steel clear height h0, is stated more clear；
In addition, floor is in T section top in conventional composite beam floor, girder steel is located at below floor, in the case where bearing load,
Floor bears hogging moment at support, is in tension state, and the girder steel top quartile of cast-in-place package Honeycomb Beam of the invention is in building
On the one hand intralamellar part saves the connection of beam slab peg, the neutral axis on the other hand making girder steel bear moment of flexure moves up, and floor tension is cut
Face area reduces, and structural safety performance gets a promotion.
