Abstract
The utility model discloses a prestressed profile steel base type T-shaped steel reinforced concrete composite beam, and belongs to the field of building components. The prestressed profile steel base type T-shaped steel reinforced concrete composite beam is composed of a prefabricated profile steel framework, a prefabricated steel reinforced concrete lower beam and a cast-in-place steel reinforced concrete upper beam. The prefabricated profile steel framework is composed of full-length tooth hole-shaped web T-shaped steel, an H-shaped steel base, prestressed steel bars and common constructional steel bars. The lower ends of tooth hole-shaped webs are connected with the H-shaped steel base. The prestressed steel bars and the common constructional steel bars are arranged on the lower part and the upper part of a lower flange plate of the H-shaped steel base respectively and are hooped through transverse stirrups to form a cage, wherein the transverse stirrups transversely penetrate through tooth holes of the tooth hole-shaped webs in a winding mode. Concrete is poured along the tooth holes of the tooth hole-shaped webs and the transverse stirrup cage to form the prefabricated steel reinforced concrete lower beam. On the spot, the steel reinforced concrete upper beam is cast in place on the lower beam along the top surface of the T-shaped steel to form the composite beam, or the cast-in-place steel reinforced concrete upper beam and a floor cast-in-place layer are integrally formed. According to the design, the self weight of a beam body is reduced, and the strength, rigidity and anti-seismic property of the composite beam are improved.

Background technology
Along with the fast development of building industry, existing conventional steel structure, wooden construction, masonry structure and reinforced concrete structure, can not meet development need, the steel reinforced concrete compound beam body structure that developed recently gets up, more traditional beam body has better performance, but, existing girder with rolled steel section en cased in concrete is the combination of single type Steel concrete substantially, along with building beam span increases, or the increasing of load, show gradually its weak point, for this reason, need exploitation can be suitable for the combining structure beam of different spans and load, acquisition is than traditional steel-concrete structure beam, bearing capacity is large, rigidity is large, the combining structure beam body that anti-seismic performance is good, to meet differing heights, the building demand of span.
Utility model content
The purpose of this utility model is to provide a kind of prestressing force shaped steel seat formula T-steel concrete combination beam, this superposed beam has that deadweight is light, cross section is less, and intensity is high, and bearing capacity is large, the feature that stability and anti-seismic performance are good, can meet compared with long span building building needs; And facilitate suitability for industrialized production and building operations.
The object of the utility model patent is achieved by the following technical solution:
A kind of prestressing force shaped steel of the utility model seat formula T-steel-concrete combination beam, by precasting reinforcing bar, prefabricated reinforcing bar concrete lower part beam and cast-in-place steel reinforced concrete top beam, formed, described precasting reinforcing bar is comprised of elongated T-steel, i shaped steel seat, prestressed reinforcement and ordinary constitution reinforcing bar, the web of described elongated T-steel is perforation shape web, in the each toothed surface of elongated T-steel perforation shape web lower end, be connected with i shaped steel seat top flange plate respectively, affixed with the junction plate that is provided with through hole respectively at the two ends of described elongated T-steel; Described prestressed reinforcement and ordinary constitution reinforcing bar are respectively on bottom and the top of i shaped steel seat bottom wing listrium, symmetrical its shaped steel seat web both sides longitudinally arrange, by transverse reinforcement hoop, walk around prestressed reinforcement, ordinary constitution reinforcing bar, and corresponding to perforation shape web perforation, hoop is connected into transverse reinforcement hoop cage, forms one-piece type reinforcing bar; Along perforation shape web perforation and transverse reinforcement hoop cage concreting, form prefabricated reinforcing bar concrete lower part beam, each i shaped steel seat top flange plate is emerging in the surface of this prefabricated reinforcing bar concrete lower part beam; At the construction field (site), on prefabricated reinforcing bar concrete lower part beam, along elongated perforation shape web T-steel end face cast-in-situ concrete reinforcing bar top beam, be shaped to compound beam; Or along elongated perforation shape web T-steel end face, implement the cast-in-place moulding of one of cast-in-situ concrete reinforcing bar top beam and precast floor slab in-situ layer.
The junction plate two ends that are provided with through hole that the two ends of described elongated T-steel connect are connected with i shaped steel connector respectively.
A kind of prestressing force shaped steel of the utility model seat formula T-steel-concrete combination beam, its precasting reinforcing bar is by elongated T-steel, i shaped steel seat, prestressed reinforcement and ordinary constitution reinforcing bar composition, bottom is divided prestressed reinforcement is set, make this structure produce compressive pre-stress at cross section lower limb, top edge produces pre-tensile stress, when beam bearing load, beam lower limb produces pulling force, top edge produces pressure, at prestressing force and load action, obtain good balance, in addition elongated T-steel web is arranged with i shaped steel seat, reduced the deadweight of girder steel, improved the intensity of compound beam, rigidity and shock resistance, during site operation, at the precast concrete lower beam two curb girder face overlap joint precast floor slabs of moulding, can implement the cast-in-place moulding of one of cast-in-situ concrete top beam and precast floor slab in-situ layer, improved whole building performance comprehensively.
