Description

A kind of SFRC deck installation structures
Technical field
The utility model is related to construction paving structure, specially a kind of SFRC deck installation structures.
Background technology
Deck paving is also referred to as runway and mated formation, and is overcoat of the making on floorings, is the important composition of bridge structure Part.Effect is that protection belongs to the carriageway plate of girder integral part not by the direct abrasion of vehicle tyre, prevent girder by The erosion of rainwater, and the load of vehicle wheel weight can be made to play certain distribution.Due to bridge floor it is natural open and by big Gas influence is very sensitive, and the quality and useful life longevity of deck paving quality will directly influence the ride quality of automobile and use Durability.
With the fast development of China's economy, the magnitude of traffic flow is growing, and bridge surface in bridge project face is mated formation layer concrete mistake Early there is crack, due to infiltration and the repeated action of vehicle, accumulate over a long period, concrete of bridge deck paving subject to severe risks of damage, This directly jeopardizes the use of beam body normal function, even results in beam body breaking-up, influences traffic safety.
The content of the invention
The utility model influences asking for traffic safety to solve existing concrete deck paving in the presence of occurring crack too early Topic is there is provided simple in construction, and endurance quality is good, and very high ductility, toughness and a kind of excellent freeze proof, anti-wear performance SFRC is presented Deck installation structure.
The utility model adopts the following technical scheme that realization:A kind of SFRC deck installation structures, including bridge beam body, Bridge beam body upper surface is provided with SFRC concrete layers, be provided between bridge beam body and SFRC concrete layers with both it is fixed and Inverted U-shaped pre-buried anchor bar, the lower end of U-shaped pre-buried anchor bar is provided with and its one and the horizontal anchor that stretches out Gu the cold rolled reinforcing bar welded mesh above U-shaped pre-buried anchor bar, SFRC concrete are provided with reinforcing bar, SFRC concrete layers Layer upper surface is provided with SBS modified-high polymer emulsified asphalt waterproof layers, and SBS modified-high polymer emulsified asphalt waterproof layers upper surface is set It is equipped with particulate formula AC-13SBS modified asphalt concretes layer.
The U-shaped pre-buried anchor bar configured in the structure design is consolidated with SFRC concrete layers so that SFRC concrete Layer be connected well with bridge beam body, stress is more abundant, and cold rolled reinforcing bar welded mesh can make SFRC materials shock resistance, Stretch-proof, compressive resistance are not fully exerted, and then ensure the intact use effect of bridge deck structure, while SBS modified-high polymers are newborn Change the use of bituminous water-proof coating, improve effect of the SFRC concrete layers from corrosion of making moist, overcome existing concrete bridge floor The problem of mating formation in the presence of occurring crack influence traffic safety too early.
The utility model reasonable in design is reliable, and pavement thickness can reduce 30%-50% under identical loading condition, reduces Quantities, reduces bridge dead load;And because it has stronger impact resistance, it is ensured that it is connected reinforcing bar with expansion joint Secure bond, substantially increases the service life at expansion joint;Bridge floor cracking is slow simultaneously, significantly reduces concrete scaling, hole The generation of groove phenomenon, extends the service life of bridge deck structure, improves the driving conditions of vehicle.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure:1- bridge beam bodies, 2-SFRC concrete layers, the pre-buried anchor bar of 3-U types, the horizontal anchor bars of 4-, 5- is cold Roll welded steel fabric, 6-SBS modified-high polymer emulsified asphalt waterproof layers, 7- particulate formula AC-13SBS modified asphalt concretes layer.
Embodiment
A kind of SFRC deck installation structures, including bridge beam body 1, the upper surface of bridge beam body 1 are provided with SFRC concrete layers 2, it is provided with and is fixed with both and inverted U-shaped pre-buried anchor bar 3 between bridge beam body 1 and SFRC concrete layers 2, it is U-shaped pre- Bury anchor bar 3 lower end be provided with its one and the horizontal anchor bar 4 that stretches out, set in SFRC concrete layers 2 The cold rolled reinforcing bar welded mesh 5 positioned at the U-shaped pre-buried top of anchor bar 3 is equipped with, it is high that the upper surface of SFRC concrete layers 2 is provided with SBS Polymerized emulsified asphalt waterproof layer 6, the upper surface of SBS modified-high polymer emulsified asphalts waterproof layer 6 is provided with particulate formula AC- 13SBS modified asphalt concretes layer 7.
In specific implementation process, U-shaped pre-buried anchor bar 3 is the HPB300 reinforcing bars of Φ 10mm specifications, and U-shaped pre-buried anchoring The length that reinforcing bar 3 stretches into bridge beam body 1 is 10 centimetres, and the length for stretching into SFRC concrete layers 2 is 4 centimetres;SFRC concrete layers 2 It is to be gathered materials by cement, thickness and the short steel fibre of random distribution is combined, and short steel fibre is in three-dimensional random distribution;Bridge The top surface of beam body 1 is scored surface;Cold rolled reinforcing bar welded mesh 5 uses the HRB400 reinforcing bars of Φ 12mm specifications, and size of mesh opening is 10cmX10cm, the distance of cold rolled reinforcing bar welded mesh 5 and the top surface of SFRC concrete layers 2 is more than or equal to 3cm.
