Construction cost is high, and fire resistance is poor, there are also chemical odors；Generally it will appear different degrees of decortication, blistering, mill using 3-5
Damage, comprehensive cost are higher.Diamond dust terrace has many advantages, such as wear-resistant, easy construction.But it is impervious, not durable, not corrosion resistant
Erosion；After a period of use, ground is easy to appear founding, plays phenomena such as dirt, dusting, hollowing, cracking.
Summary of the invention
The technical problem to be solved by the present invention is to, a kind of ultra-high performance concrete abrasion-proof terrace is provided, including according to
The secondary ordinary reinforced concrete layer and ultra-high performance concrete layer being laid on above blinding layer, the ordinary reinforced concrete layer
Interface between ultra-high performance concrete layer is coarse faying face, is painted with interface cohesion agent on the coarse faying face.
In above scheme, the interface cohesion agent is epoxy resin structural adhesive.
In above scheme, the ultra-high performance concrete layer with a thickness of 30mm~150mm.
In above scheme, ultra-high performance concrete abrasion-proof terrace is poured using framing, at the connecting sewing between two width terraces
Equipped with the distributing bar for connecting adjacent terrace, distributing bar is embedded in ultra-high performance concrete layer.
In above scheme, the distributing bar includes transverse steel and longitudinal reinforcement, the transverse steel and longitudinal reinforcement
The plane at place is mutually perpendicular to.
In above scheme, the transverse steel is umbrella hook-type.
In above scheme, the transverse steel is U-shaped, and the longitudinal reinforcement is located inside U-shaped opening.
The ultra-high performance concrete abrasion-proof terrace for implementing the utility model, has the advantages that
1, the utility model effectively increases the wear-resistant of terrace, shock resistance, impermeable, anti-using ultra-high performance concrete
Corrosive nature significantly improves the durability of terrace, substantially prolongs the service life of terrace；
2, the working procedure of the utility model terrace is simple, short construction period, operation phase maintenance cost are few, life cycle cost
It is low, there is good economy.
3, the utility model combines the respective advantage of normal concrete and ultra-high performance concrete, significantly increases ground
Wear-resistant, shock resistance and impermeable performance have many advantages, such as wear-resisting, shock resistance, antiseepage, are easy to construct, long service life,
Newly-built or transformation factory, machine shop, warehouse, airfield runway, harbour, parking lot, dam floodway etc. have wide application
Prospect.
