Abstract
The utility model relates to a composite beam bridge deck structure with a replaceable bridge deck slab. The composite beam bridge deck structure comprises the bridge deck slab and a replaceable connecting part, wherein the replaceable connecting part is arranged on the upper surface of a main beam of a bridge body; a preset pouring hole corresponding to the replaceable connecting part is formed in the bridge deck slab; the bridge deck slab is laid on the main beam of the bridge body, so that the preset hole is located in a position of the replaceable connecting part; and concrete is poured in the preset pouring hole, so that the bridge deck slab is connected with a main beam of the bridge body, so that a whole is formed. Compared with the prior art, the replaceable bridge deck slab is provided, the construction progress is effectively accelerated, and the service life of the structure is prolonged.
Description
Technical field
The utility model relates to a kind of bridge deck structure, especially relates to the removable compound beam bridge floor of a kind of bridge deck structure.
Background technology
Reinforced concrete bridge deck plate and steel bridge deck are two kinds of bridge deck structures commonly used.Steel bridge deck normally consists of the stiffening rib in length and breadth of steel plate and welding, its fluid concrete not above steel plate, directly black top road surface.With concrete slab, compare, steel bridge deck is lighter, and construction quality easily guarantees, asphalt road surface immediately after bridge deck set up, reduction of erection time.But also there are the shortcomings such as rigidity is lower, flexible pavement easily damages, cost is higher.The Steel concrete combining structure is with its whole stressed economy, and the reasonability of performance bi-material advantage separately and the outstanding advantages of constructability and be widely used have been built a large amount of various forms of composite bridges.Modal composite bridge is the combined steel plate beam bridge, by using connector, plate girder and concrete slab is combined, and bending rigidity can increase substantially, and reduces deck-molding, increase across footpath.
The endurance issues of built bridge more and more causes people's concern, and steel corrosion and concrete cracking are the subject matter that affects durability, and it not only affects the application life of structure, also can cause a large amount of potential safety hazards, even causes the accident.Wherein, bridge deck directly bear vehicular load and environmental load, to be subject to the unfavorable factors such as overload, corrosion and fatigue to affect the most direct member, and traditional concrete slab and steel bridge deck are understood very fast corrosion, ftractureed, peel off under some rugged environments, these bring huge hidden danger and loss to road traffic.Therefore, be necessary to improve bridge deck, improve the service life of bridge.
The utility model content
The purpose of this utility model is exactly to provide the removable compound beam bridge floor of a kind of bridge deck structure in order to overcome the defect that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions:
The removable compound beam bridge floor of a kind of bridge deck structure, comprise bridge deck and changeable type connector, described changeable type connector is arranged at the upper surface of pontic, described bridge deck are provided with the reserved pouring hole corresponding with the changeable type connector, bridge deck are laid on pontic, make the position of reserved pouring hole in the changeable type connector, in described reserved pouring hole, concreting makes bridge deck and pontic be connected to form integral body.
Described changeable type connector comprises bottom steel plate and shear connector, and described bottom steel plate is fixedly connected with the pontic upper surface, and described shear connector is arranged on the steel plate of bottom.
