It is applied to the secondary beam in the secondary beam and girder or xoncrete structure of steel construction.
Background technology
In building structure, between girder steel and floor combination stressed so that the bending rigidity of combination beam and anti-bending bearing capacity
It is significantly greater than girder steel.And in actual engineering design, combination beam effect often more cannot accurately consider and make full use of；And
During actual design, calculate for simplifying, sometimes do not consider the bending rigidity to beam for the floor and the raising of anti-bending bearing capacity, cause girder steel
The waste of material, increased deck-molding, decreases indoor pure space.For making full use of girder steel material, play girder steel and beams of concrete
Combined effect, new combined beam structure needs to be proposed.
Content of the invention
For problem above, the present invention propose a kind of H+T shape part and its with floor combination beam, in girder span stage casing, girder steel
Employ the H+T tee section different from traditional H-shaped (or I shape), floor is shelved on the upper surface of H section bar top flange, on floor
The layer solderable upper surface on the T section edge of a wing of reinforcing bar.Beam is H+T type section, and effective cross-section height cuts more than traditional H-shaped
Face, can effectively improve bending rigidity and the anti-bending bearing capacity of beam.Therefore in same building floor height, beam span and load case
Under, using H+T tee section, under floor, less deck-molding can reach same beam bending rigidity and anti-bending bearing capacity；Deck-molding
Reduce, then indoor use clear height increases, and beam steel using amount is reduced, and can reach economic and practical purpose.In addition only in beam
Span in the middle part of moment of flexure large area setting T-steel, material-saving.
The present invention provides a kind of H+T shape part, including：T profile and H section bar；The edge of a wing of T profile and two wings of H section bar
Edge is parallel, and the web of T profile is in straight line with the web of H section bar, and T profile is fixed on H section bar, or both are integrally formed.
Further, the present invention provides a kind of H+T shape part, also has following characteristics：The length of T profile is less than or equal to H
Section bar.
Further, the present invention provides a kind of H+T shape part, also has following characteristics：Also include several shear keies, setting
One or both sides in T profile span direction.
Further, the present invention provides a kind of H+T shape part, also has following characteristics：T profile is in H section bar span
Between position.

Further, the present invention provides a kind of H+T shape part and floor combination beam, also has following characteristics：Reinforcement welding is solid
It is scheduled in T profile.
The present invention provides a kind of H+T shape part and floor combination beam, when using as building structure secondary beam, can be by girder steel
H-shaped web be connected with girder by bolt, realize secondary beam and be connected with main beam pivot.Because girder steel height (counts T steel
Highly) more traditional H-shaped girder steel increases, and the section rigidity of secondary beam obtains larger raising.
The present invention provides a kind of H+T shape part and floor combination beam, H-shaped beam section (no T steel) top flange weld stud or
Other shear keies of person.The height of T steel is just floor top bars bottom level, thus being conducive to reinforcing bar positioning it is ensured that steel
The thickness of tendon protective layer.
It is H+T new type section that the present invention provides a kind of H+T shape part and floor combination beam, equally building floor height, beam span
Under load case, effective cross-section height is more than traditional H-shaped section, can effectively improve the bending rigidity of beam and bending resistance carries
Power.Deck-molding reduces, then indoor use clear height increases, and beam steel using amount is reduced, and can reach economic and practical purpose.Separately
Outward, because web both sides are constrained by concrete, therefore web ratio of height to thickness limit value can greatly loosen T profile, saves further
Steel using amount.
