Background technology
Domestic construction adopts reinforced concrete structure more at present, reinforced concrete structure has good stability, good endurance, but from great feature, in long span building structure, reinforced concrete beam is because deadweight is larger, in the time meeting the demand of large span, depth of beam is generally all special large, therefore causes the functional performance of building to be affected.For this reason, develop the superposed beam of different shaped steel, reinforcing bar and concrete one, obtain and conduct oneself with dignity with highly relative little than traditional girder with rolled steel section en cased in concrete, the reinforced concrete composite structure beam body that structural bearing is large, rigidity is large, anti-seismic performance is good, to meet the building demand of differing heights, span.
Utility model content
The purpose of this utility model is to provide a kind of prestressing force i shaped steel inverted T-shape cross section concrete folding beam, this superposed beam beam height is less, deadweight is lighter, stability and anti-seismic performance are good, can meet the highrise building needs of having relatively high expectations compared with large span, interior.
The utility model is achieved in the following ways:
A kind of prestressing force i shaped steel inverted T-shape of the utility model cross section concrete folding beam, by precasting reinforcing bar, prefabricated reinforcing bar concrete lower part beam and cast-in-place steel reinforced concrete top beam composition, described precasting reinforcing bar is by perforation shape web i shaped steel, prestressed reinforcement, plain bars composition, perforation shape web i shaped steel two ends are affixed with the stiffener that is provided with through hole, prestressed reinforcement is arranged on the bottom wing listrium upper surface of the perforation shape web both sides of perforation shape web i shaped steel, plain bars is arranged in the both sides of bottom wing listrium, in vertical, stirrup interval arranges, walk around perforation shape web i shaped steel top flange plate, the internal layer plain bars of bottom wing listrium bottom surface plain bars and perforation shape web both sides, hoop is connected into reinforcing cage, laterally outer stirrup is walked around the outer plain bars of bottom wing listrium both sides, level is crossed the perforation of perforation shape web of perforation shape web i shaped steel around bottom wing listrium, hoop is connected into reinforcing cage, be integrally connected with elongated perforation shape web i shaped steel, stirrup cage concreting along the perforation of perforation shape web and laterally, forms prefabricated reinforcing bar concrete lower part beam, at the construction field (site), on prefabricated reinforcing bar concrete lower part beam, along vertical interior stirrup cage cast-in-situ concrete reinforcing bar top beam, be shaped to inverted T-shape cross section superposed beam, or the steel reinforced concrete top beam of enforcement inverted T-shape cross section superposed beam and the cast-in-place moulding of one of precast floor slab in-situ layer.
The top flange plate thickness of described perforation shape web i shaped steel is greater than bottom flange plate thickness.
Insert respectively in the corresponding aperture of two ends stiffener at described prestressed reinforcement, plain bars two ends.
Top stirrup and the top flange plate of described vertical interior stirrup are affixed.
Described laterally outer stirrup is affixed with vertical interior stirrup intersection point place.
Described perforation shape web i shaped steel two ends stiffener is connected with respectively H shaped steel connector, and this H shaped steel connector web has connecting hole.
The utility model prestressing force i shaped steel inverted T-shape cross section concrete folding beam is by precasting reinforcing bar, precast concrete lower beam and cast-in-situ concrete top beam composition, this concrete-steel Beam has had reasonable in design, conduct oneself with dignity lighter, cross section is less, well balance the compressive stress of the concrete tensile stress in bottom and top steel plate, avoid the pressurized unstability of concrete cracking and reinforcing bar, form stable composite beam, cast-in-place top beam is connected with floor in-situ layer one, globality and anti-seismic performance are not only strengthened, and increase the effective usage space of building, being convenient to batch production produces, the perforation of perforation shape web, facilitate the laying of preheating embedding line, easy for installation, can meet compared with the middle-high building demand of large span.
