Abstract
The utility model discloses a PBL (Planetary Boundary Layer) shear connector structure of a flange plate. Aiming at a combined structure, before a steel beam and concrete are joined by adopting a shear connector to form an I-shaped beam or an H-shaped beam, holes 3 are symmetrically formed on a steel beam flange plate 2; and then a steel beam web plate 1 and a steel beam flange plate 2 are manufactured to form the steel beam.
Description
Technical field
The utility model relates to a kind of novel frange plate PBL shear connector structure, is used for connecting the girder steel and the concrete bridge deck of combining structure bridge, belongs to the bridge construction field.
Background technology
Steel-concrete composite beam combines steel, two kinds of different materials of concrete rightly, has improved the service efficiency of stability of structure, intensity and material.Steel-concrete composite beam is a kind of important horizontal load-bearing combined member; It is combined into whole bearing load to girder steel and concrete flange plate through shear connector, thereby makes compound beam can give full play to steel tensile property and the good advantage of concrete compressive property.
Shear connector is to guarantee in the combining structure one of primary structure member that two kinds of different materials co-operation are the most key, makes steel work that modulus of elasticity has a big difference very with integral body of concrete structure formation and co-operation.Shear connector has played the horizontal shear at opposing steel and concrete interface place, prevents the effect of the mutual slippage of level between the two.It is directly connected to the supporting capacity of whole compound beam.Difficult point wherein is the vertical equity shearing that utilizes rational connector to control effectively to take place between steel and the concrete material.
Shaped steel connectors such as socket cap weldering nail and angle steel, channel-section steel are one of connectors the most frequently used in the present concrete structure, and the fatigue problem at its root weld place is also more outstanding.
Frange plate PBL shear connector, promptly be with the steel plate that is provided with circular hole along force direction, be embedded in the concrete and use as connector.A kind of heavy connection that the armored concrete slab and the bottom girder steel on top is combined into whole cooperative combination flexural member.
The utility model proposes a kind of novel frange plate PBL shear connector structure, has safe and reliable, easy construction technical characterstic efficiently.
The utility model content
The technical problem that the utility model will solve is a frange plate PBL shear connector structure, make attachment security between two kinds of materials of steel and concrete reliable, construct convenient.
So-called frange plate PBL shear connector structure is that the frange plate in the girder steel is holed or punching in advance, through manufacturing i beam or H shaped steel, builds a kind of antifatigue shearing connecting key structure that forms behind the bridge deck.In the perforate of frange plate symmetry, frange plate thickness, perforated area, spacing and quantity can be definite through calculating.Frange plate PBL shear connector structure does not need to process especially, and circular port only is set on steel plate; Reduced a large amount of in the past welding sequences; When thickness of slab, pitch-row are provided with when appropriate, its destruction is concrete shearing in the hole, does not receive tired influence.
The utility model is realized through following technical scheme: frange plate PBL shear connector structure comprises steel frange plate, steel web and frange plate perforate in the composition.
The technological progress that the utility model is obtained is: in the structure, frange plate perforate concrete block forms the anti-shear concrete pin after the moulding.Coagulation shear-pin opposing horizontal shear.This combining structure shear connector co-operation is safe and reliable, easy construction.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is explained further details:
To like Fig. 1,2,3, the frange plate PBL shear connector structure shown in 4, before being made into i beam or H shaped steel, girder steel frange plate 2 symmetries are opened the circular hole 3 in the frange plate, steel beam web plate 1 is made into girder steel with girder steel frange plate 2 again.
As stated, just can realize the utility model.
