Abstract
The utility model discloses a prefabricated decking for the bridge construction technical field that is under construction, including tetragonal steel bottom plate, steel bottom plate's edge all around all is equipped with decurrently to one side buckles, and steel bottom plate passes through it forms the chamfer at edge all around to buckle, and steel bottom plate's top surface sets up the steel fiber concrete layer, the steel fiber concrete layer is including the concrete layer and the horizontal and tendon of longitudinal arrangement in concrete layer of pouring, the both ends of tendon all form the end of stretching out the concrete layer terminal surface outside. The laminiform one -tenth of steel bottom plate and steel fiber concrete prefabricated decking's major structure, reduction decking weight that can be by a relatively large margin under the same bearing capacity condition and measuring with the steel to be favorable to reducing the cost of bridge, simultaneously, steel bottom plate chamfer all around makes prefabricated decking satisfy the minimum gauge requirement of installing on the uncovered lattice formula girder steel, and further the reduction is measured with the steel, in addition, joint strength is then guaranteed to the end of tendon formation when the wet seam between the decking is pour.
Description
Technical field
The utility model is used for bridge building operations technical field, particularly relates to a kind of prefabricated bridge.
Background technology
Along with the Large scale construction of highway in China, railway through street net, build one after another in a large number across river, river, sea-bridge beam, concrete-steel Beam is one of common load-carrying members of various arch bridge, cable stayed bridge, suspension bridge.For by the girder steel installing the erection of concrete slab order after first setting up girder steel, the uncovered lattice often of girder steel now, this kind of erection of main beam construction conventional method is: first set up girder steel, then install concrete slab, the wet seam between last concreting bridge deck.
In the structure of bridge, the bridge deck usually adopted are configured with concrete slab, superimposed bridge deck and steel bridge deck, concrete slab and superimposed bridge deck are conducted oneself with dignity larger, cause the overall dead load of bridge relatively bigger than normal, cause bridge that difficulty is installed, have impact on the economy of integral bridge; And although steel bridge deck deadweight is comparatively light, from the situation of domestic application, design, difficulty of construction are comparatively large, and reality rarely has the person of producing a desired effect in using, and rolled steel dosage is large, material of paving course unit price is high, causes overall cost higher.
Utility model content
For solving the problem, the utility model provides a kind of and has lightweight, that steel using amount is few, Engineering Overall expense is low prefabricated bridge concurrently.
The utility model solves the technical scheme that its technical problem adopts: a kind of prefabricated bridge, comprise the steel sole plate of quadrangle, the edge of steel sole plate is equipped with bending obliquely, steel sole plate forms chamfering by described bending in edge, the end face of steel sole plate arranges steel fibrous concrete layer, described steel fibrous concrete layer comprises the layer of concrete and the horizontal and vertical tendon be arranged in layer of concrete of building, and the two ends of described tendon all form the termination of stretching out outside layer of concrete end face.
Be further used as the improvement of technical solutions of the utility model, in described layer of concrete, be provided with the PBL shear connector strip-shaped steel plate that some transverse directions are arranged on steel sole plate end face, be provided with some installation positions passed for tendon along described PBL shear connector strip-shaped steel plate.
Be further used as the improvement of technical solutions of the utility model, described installation position comprises a ranking in the square groove of PBL shear connector strip-shaped steel plate top and the circular hole of a ranking below square groove.
Be further used as the improvement of technical solutions of the utility model, the corresponding square groove of described tendon and circular hole arrange two-layer.
Be further used as the improvement of technical solutions of the utility model, described PBL shear connector strip-shaped steel plate welds with steel sole plate is elongated, and PBL shear connector strip-shaped steel plate equidistantly distributes at steel sole plate end face.
Be further used as the improvement of technical solutions of the utility model, described steel sole plate thickness is 8mm, and steel fibrous concrete layer is the thick CF50 concrete of 150mm, also comprises the hanger stretched out by described layer of concrete end face corner.
The beneficial effects of the utility model: steel sole plate and steel fibrous concrete layer form the agent structure of prefabricated bridge, can reduction bridge deck weight by a relatively large margin and steel using amount under same bearer power condition, thus is conducive to the cost reducing bridge; Meanwhile, the chamfering of steel sole plate surrounding makes prefabricated bridge meet the minimum thickness requirement that uncovered lattice girder steel is installed, and reduces steel using amount further; In addition, the wet seam of termination then between bridge deck that tendon is formed ensures bonding strength when building.
