Description
A kind of prestressing force perforation of the present invention shape web T-steel concrete combination beam, belongs to building unit field.
Background technology
Along with the fast development of building industry, existing conventional steel structure, wooden construction, masonry structure and reinforced concrete structure, development need can not be met, the transfer structure for SRC beams 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 its weak point gradually, for this reason, need exploitation can be suitable for the combining structure beam of different spans and load, obtain 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.
Summary of the invention
The object of this invention is to provide a kind of prestressing force perforation shape web T-steel concrete combination beam, T-steel web is perforation shape, reduce shaped steel deadweight, strengthen the engaging force of concreting and shaped steel simultaneously, improve bearing capacity and the anti-seismic performance of transfer structure for SRC beams.
The object of the invention is to be achieved through the following technical solutions:
A kind of prestressing force perforation of the present invention shape web T-steel concrete combination beam, be made up of precasting reinforcing bar, prefabricated reinforcing bar concrete lower part beam and cast-in-place steel reinforced concrete top beam, described precasting reinforcing bar is made up of elongated perforation shape web T-steel, prestressed reinforcement, ordinary constitution reinforcing bar, described elongated perforation shape web T-steel two ends have the affixed stiffener being provided with through hole respectively, are provided with the needling vertically overhanging to both sides at the castellated plates basifacial of its perforation shape web, prestressed reinforcement, ordinary constitution reinforcing bar respectively symmetrical elongated perforation shape web is arranged on around needling, its two ends are corresponding respectively inserts in the corresponding aperture of stiffener, and be connected into transverse reinforcement hoop cage through transverse reinforcement hoop through perforation shape web perforation hoop, be integrally connected with elongated perforation shape web T-steel, along elongated perforation shape web perforation and transverse reinforcement hoop cage concreting, form precast concrete reinforcing bar yi word pattern lower beam, at the construction field (site), in precast concrete reinforcing bar yi word pattern lower beam, along the cast-in-situ concrete of elongated perforation shape web T-steel end face, prefabricated steel reinforced concrete top beam, be shaped to compound beam, or it is cast-in-place shaping along the one of elongated perforation shape web T-steel end face enforcement cast-in-situ concrete reinforcing bar top beam and precast floor slab in-situ layer.
The symmetrical elongated perforation shape web of described prestressed reinforcement is separately positioned on the upper and lower of needling, and ordinary constitution reinforcing bar is located at prestressed reinforcement both sides respectively.
Described perforation shape web T-steel two ends stiffener, be connected to H profile steel connector, this H profile steel connector web has connecting hole.
A kind of prestressing force perforation of the present invention shape web T-steel concrete combination beam, T-steel has perforation shape web, reduce the deadweight of girder steel, enhance shape steel web and concrete bonding force when building simultaneously, not only improve the bearing capacity of girder steel to a certain extent, profile of tooth web both sides are provided with symmetrical needling, on the basis not being significantly increased shaped steel weight, needling is as a part for precasting reinforcing bar, effective enhanced type steel and concrete bonding force, improve the integrated carrying ability of structure, needling top and the bottom are provided with prestressed reinforcement simultaneously, when beam bearing load, beam lower limb produces pulling force, top edge produces pressure, can well be balanced when prestressing force and load action, improve arrangement works performance, improve the use ability of beam, and during site operation, the one can implementing cast-in-situ concrete reinforcing bar top beam and precast floor slab in-situ layer is cast-in-place shaping, meet the civilian and public building needs of the middle low layer of general span.
