Description
Technical field
The utility model belongs to bridge structure technical field of buildings, and in particular to a kind of steel-ultra-high performance concrete combination
Deck paving seam construction and construction method.
Background technique
It is in recent years to solve the problems such as traditional temperature sensitive property of paving steel bridge deck is high, and fatigue life is short, steel-very-high performance
Concrete combined bridge deck starts to promote and apply in Steel Bridge Pavement at home.Due to this kind of paving structure have self weight compared with
The small, outstanding features such as bearing capacity is high, fatigue life is long, can increase substantially paving steel bridge deck design, service life, by bridge
The extensive concern of engineering circles.But due to having added a large amount of steel fibre in ultra-high performance concrete, concrete mixes and stirs, pours and apply
Work difficulty is big, speed is slow, large-stride steel bridge deck application when have to framing pour, health, thus inevitably bring
Concrete joint problem.
In order to enhance the intensity of ultra-high performance concrete plate seam crossing, it is typically employed in the direct weld reinforcement steel plate of seam crossing
Mode, as patent CN108396647A discloses a kind of steel-ultra-high performance concrete combined bridge deck connection structure, including embedding
In in ultra-high performance concrete layer, for connecting the reinforcement connecting elements of two steel bridge deck elementary layers, the reinforcement connects structure
Part includes: the steering component on the steel bridge deck elementary layer；Binding prestress reinforcement, for connect be located at it is adjacent described in
The steering component on steel bridge deck elementary layer.Steel bridge deck elementary layer connecting sewing is improved by above-mentioned reinforcement connection building
