Description
Technical field
This patent is related to a kind of floorings of use UHPC clad cans and is longitudinally continuous structure.
Background technology
For the continuous structural system of structure freely-supported bridge floor, its continuous structure is general in the pre-buried shaped steel of prefabricated beam-ends, utilizes
Across the pre-buried shaped steel Site Welding formation continuous structure of seam steel plate and precast beam, the construction and installation connection required precision of the construction compared with
Height, the tolerance of construction is slightly inferior, and project application situation is poor, much all occurs leak.
For the continuous system of structure after first freely-supported, because it is related to the conversion of system, and it is general on middle pier structure top
Portion need to set prestressing force to improve the larger tension in hogging moment area, and working procedure is slightly complicated, and construction period is also slightly longer.
Structure freely-supported, floorings continuous structure be between a kind of foregoing structural system between the two, at present compared with frequently with
It is continuous for back plate, and configure in hogging moment area prestressing force, small box girder top plate is continuous, by set prestressing force meet stress and
Demand of anti-crack, slightly unfortunately scene needs sequence of prestressing, and simplicity is slightly inferior.
The content of the invention
Structure is longitudinally continuous the technical problem to be solved in the present invention is to provide a kind of floorings of use UHPC clad cans, it has
Have easy construction, dimension is supported convenient, durability more preferably, anti-cracking waterproof, the advantage of the flexural tensile stress in resistance continuous structure.
To solve the above problems, the present invention is adopted the following technical scheme that：
The floorings of the use UHPC clad cans of the present invention are longitudinally continuous structure, including the superstructure that left and right is oppositely arranged is pre-
Beam processed, it is characterised in that：The lower end of the superstructure precast beam is provided with the non-bent cap of falling T or the bent cap of falling T, the superstructure
The upper surface that precast beam is located between the left and right sides is equipped with UHPC layers, the upper surface of the superstructure precast beam and is located at
The UHPC layers of left and right sides are equipped with conventional concrete pave-load layer.
The above-mentioned bent cap of falling T is the bent cap of falling T structure, and the superstructure precast beam positioned at the bent cap of the falling T both sides is additionally provided with
One layer of bridge deck concrete is wet to be connect section and is rigidly connected by the wet section that connects of bridge deck concrete with superstructure precast beam.
Above-mentioned UHPC layers is laid on the wet upper surface for connecing section of concrete.
Above-mentioned UHPC layers width is 1860mm.
Above-mentioned UHPC layers width is 1000mm, and the thickness of described UHPC layer and conventional concrete pave-load layer is 80mm.
The beneficial effects of the invention are as follows：
The present invention is longitudinally continuous structure using a kind of floorings of novel high-strength toughness concrete material UHPC clad cans, its profit
There is the performances such as high-strength, high tenacity, good endurance with UHPC materials, start to use in science of bridge building recently.In view of UHPC materials
Expect self-characteristic, intend carrying out the local clad can of bridge floor continuous structure using UHPC, form new bridge floor continuous structure, reach construction
Tolerance is strong, easy construction, the more preferable purpose of durability, meanwhile, connect section reinforced concrete structure and UHPC mats formation shape using wet
Flexural tensile stress into combination structural union resistance continuous structure, two schemes can reach the purpose of construction anti-cracking waterproof.
