Description
Technical field
The utility model belongs to bridge member and its technical field of construction, especially a kind of type suitable for Large Span Bridges
Steel-UHPC compoboard longitudinal rib interlaced arrangement construction.
Background technique
Since concrete slab will undertake the horizontal component from suspension cable in conventional combination girder stayed-cable bridge, therefore it is average
Thickness is thicker, generally higher than 26cm, and the ratio for causing floorings to account for girder total weight is larger, overweight often 70% or more
Girder is the principal element for limiting the span of bridge upper limit, so that when the across footpath of steel-concrete continuous system beam bridge is more than 110m not
Economy, the combination girder stayed-cable bridge economic span upper limit are 600m.Simultaneously as the loading characteristic of cable-stayed bridge, with beam section and Sarasota
Distance reduction, the axle power in beam section gradually increases, therefore will bear very big axle power close to the beam section of Sarasota；For continuous beam
Bridge, the tensile stress that inner-support hogging moment bears the region floorings is much larger than other positions.
Ultra-high performance concrete (Ultra-High Performance Concrete, UHPC, hereinafter referred to as UHPC) has
Excellent mechanical property occurs making the developing trend of bridge construction structure in greatly across change, lightness.However, since UHPC makes
Valence is higher, and the thicker plate thickness of use cannot make full use of the economic advantages of UHPC, and in practical bridge structure, if pressing traditional group
The construction of beam is closed, girder steel is arranged in vertical bridge to corresponding, then to overcome axle power excessive in girder, need to increase bridge floor board size or increasing
Add girder steel panel thickness, this will cause to thicken transition area design and construction technology it is sufficiently complex, reduce economy.Therefore, for
The floorings of steel-UHPC combination beam preferably optimize seam crossing construction and combination beam stringer lateral arrangement construction, so that it is difficult to reduce construction
Degree and cracking risk, while solving the problems, such as that girder near Cable-stayed Bridge Pylon, continuous beam inner-support top floorings axle power are excessive.

Arrangement, direction across bridge parallel arrangement, seam crossing concrete in tension, so that seam crossing concrete is easy to crack under hogging moment effect；And
The utility model Shaped Steel-UHPC compoboard indulge bridge to two adjacent longitudinal ribs in direction across bridge by the way of interlaced arrangement, this
Seam crossing part UHPC will be in pressured state under arrangement, reduce cracking risk, have seam crossing section more preferably
Mechanical property.
(3) traditional steel-concrete composite beam cable-stayed bridge is to solve the problems, such as that girder axle power is excessive near Sarasota, generally takes
Increase bridge floor plate thickness or encrypt the measure of girder steel longitudinal rib, but will cause waste of material, while also will increase bridge construction
Cost, and the utility model Shaped Steel-UHPC compoboard longitudinal rib takes the construction of interlaced arrangement in seam crossing, only needs basis in this way
The increase degree of girder axle power suitably encrypts longitudinal rib, but is not required to the longitudinal rib of the encryption lesser girder of axle power, it is possible thereby to well
Solving the problems, such as Sarasota, nearby girder axle power is excessive, makes full use of material, reduces bridge construction cost, has economical well
Property.
(4) the utility model Shaped Steel-UHPC compoboard interlaced arrangement is constructed, by adjusting floorings, fashioned iron
The horizontal spacing of size and fashioned iron can facilitate the vertical, horizontal rigidity of matching floorings.
(5) since floorings are prefabricated in the factory, scene only needs to pour the wet seam of vertical, horizontal, cast in situs amount
Small, workload is small, and seam crossing reinforcing bar is not needed to overlap yet or be welded without bending and binding, easy to operate, equipment investment is small,
It is simple to operation, lower to labor quality and technique requirement.
