Description
Technical field
This utility model relates to a kind of plate-girder field, particularly to a kind of steel concrete flitch beam.
Background technology
Shearing connecting piece is the key component in steel-concrete combination beam, and it should bear and promote shaped steel and the coagulation soil phase
Shearing force to the changing of the relative positions, bears again and promotes what both separated to start power；Therefore, shearing connecting piece design and the quality of welding
Directly decide quality and the effect of combination beam；Steel channel connector material usage is big, the palpus substantial amounts of channel-section steel of consumption, on the other hand,
The cutting processing amount of channel-section steel is big, and the cost of manufacture of connector is higher, additionally, because channel-section steel and concrete slab are that strip face connects
Touching, these faces are directed predominantly perpendicular to the span direction of beam, therefore steel channel connector has certain weakening effect to the intensity of concrete；
It is bigger that bendbor connectors consumes steel material；Meanwhile, existing steel concrete flitch beam, because of hinge seam structure reason, easily occur
Damage causes hinge seam part or even all lost efficacy, and this will directly affect the integral working of each plate shared vehicular load,
Increase the internal force of plate-girder thus cause plate-girder disease.
Utility model content
The purpose of this utility model is to provide a kind of simple structure, and making, welding conveniently, are saved material, reduced cost,
Safe and reliable steel concrete flitch beam.
To achieve these goals, the technical solution of the utility model is:
A kind of steel concrete flitch beam, including girder steel, and is positioned at the concrete flange plate at girder steel top, described concrete
Arranging trapezoidal supporting plate between wing plate and girder steel, at least two anti-shearing connector is laid in the inside of described supporting plate, anti-
Shearing connecting piece is the reinforcing bar in " Z " font, and adjacent anti-shearing connector symmetry is connected with each other successively, adjacent anti-shearing company
Fitting connect after "U" shaped in band wing, be installed with a horizontal reinforcing bar, anti-shearing connector and torr between anti-shearing connector
Laying steel bonding glue-line between plate base contact surface, the bottom of anti-shearing connector is implanted with bolt, and described steel beam bottom both sides are divided
Not arranging baffle plate and securing plate, described securing plate is trapezoidal, and described baffle plate one side is connected with girder steel, another side connects with securing plate
Connect.
Further, the by-level of described concrete flange plate lays a steel screen layer.
Further, both sides, described girder steel top are respectively symmetrically and arrange angle steel.
Further, the length wherein of described securing plate is equal to the length on baffle plate wherein one side.
This utility model is a kind of steel concrete flitch beam, and it has the beneficial effect that
Anti-shearing connector of the present utility model is the reinforcing bar in " Z " font, simple structure, making, welding convenience, by
Formed in reinforcing bar and girder steel top flange and close " Z " font, between reinforcing bar and concrete almost cannot relative movement, connector shearing resistance
Cutting and resisting starts very competent, connects extremely reliable, and connector will not form vertical or horizontal crack between concrete, will not
Weaken vertical and horizontal intensity and the rigidity of concrete, compared with the various shearing connecting pieces used now, the steel of " Z " font
Muscle connector material consumption is minimum, cost-effective；Paste steel bonding glue-line at the reinforcing bar of " Z " font with the upper limb of girder steel, strengthen it
Cooperative bearing ability.
