Description
Technical field
The present invention relates to combinative structure field, especially relate to the combination beam attachment structure of a kind of tape welding nail and answer
With.
Background technology
The most same cross section of combinative structure or each rod member have the structure that two or more material makes, because of its material profit
With rationally, the advantage such as convenient of constructing, extensively applied in road and bridge and building field.In recent years, combinative structure is even
Continuous beam gradually replaces simply supported beam because of the advantages such as comfortable, building height is little, good integrity of driving a vehicle, and becomes combinative structure beam
The main expression-form of formula bridge.
At present, in steel performance, girder steel joint area typically has two kinds of versions, welding and bolt
Connect.Welding can produce bigger construction error；And residual stress can be produced, for girder steel part fatigue extremely
Unfavorable.But latching mechanism is simple, it is reliable to connect, quick construction, be convenient to mount and dismount.Therefore, many employings in engineering
Bolt carries out the connection of girder steel.
But, in steel performance, girder steel joint area bolt typically has two kinds of versions, at knot
Structure position is not provided with shear connector and welds shear connector on the upper splice plate of structure position.If in structure
Position is not provided with shear connector, and steel at this can be caused more weak with the combination of concrete, and girder steel can bear bigger lotus
Carry so that original weak jointing stress is the most unfavorable.Cut if welded on the upper splice plate of joint area
Power connector, often have influence on high-strength bolt tightens operation, causes the layout quantity of shear connector to be limited
System.And under load action, the stress of shear connector will be transferred directly to splice plate so that upper splice plate
Bear bigger Local Loads, the local of upper splice plate can be caused to start or lever up, the lever starting or levering up
Effect can produce bigger effect at high-strength bolt position, splice plate may be caused directly to come to nothing with girder steel, cause
Both are made directly to produce relative slip or the changing of the relative positions.As fruit structure bears bigger load width or steel and concrete
Between bear bigger tension load, the shear connector of joint area there will be fatigue rupture phenomenon.
Therefore, a kind of novel steel and concrete combination beam joint construction are developed for ensureing between steel and concrete
Effectively connect and the fatigue strength tool of raising connecting portion is of great significance.
