Background technology
Along with the continuous development of modern road traffic, cement concrete is the same with bituminous concrete, becomes the main constructional materials of high grade highway pavement (bridge floor).Simultaneously, road surface (bridge floor) concrete functional performance is most important for the safety of system-wide segment structure, efficiency of operation etc.And adverse weather condition (as extreme sleet, freezing weather etc.) is totally unfavorable to the dynamic property and the safety of vehicle ', and the friction factor of pavement abrasion layer freezes because of snowfall and sharply reduces.Especially in some areas, China south, sleet disaster especially severe, cause highway pavement and some key road segments that serious icing phenomenon takes place, the traffic accident incidence increases considerably, in case the generation traffic accident will make traffic at a standstill completely, and have short-term can not reparation property, cause the decline significantly of traffic transport power, its loss is inestimable.The traffic accident that China causes because of winter is freezing over the years accounts for 30% of annual traffic accident, and accident rate is at ordinary times 4～5 times.Therefore, the conventional concrete road slab is designed, put forth effort to promote the antifreeze anti-slide performance of road slab structure, effectively promote the emergency reaction mechanism and the ability of road surface (bridge floor) structure, reduce accident rate, have the significant social meaning complicated environmental condition.
At present, several snow melt de-icing methods that highway pavement is commonly used mainly comprise artificial or the mechanical removal method, spread Snow Agent method, conducting concrete and heating cable deicing or snow melting etc.But numerous research datas show, still there is certain problem in the freeze proof anti-skidding technology in existing road surface, a large amount of Snow Agent of using can be damaged existing Pavement Performance, and conducting concrete and heating cable method etc. remain in bigger actual application problem, and slow as thawing speed, intelligent degree is low, efficient is low, energy consumption is big etc., thereby be badly in need of to seek high-intelligentization and the more excellent anti-slip technology of deicing cling property, and current research for this field is the focus direction of the antifreeze antiskid technology in road surface just.
Phase-changing energy storage material is meant in its thing phase change process, can carry out energy exchange (absorb heat or emit heat to external environment from external environment) with external environment, thereby reaches the material that control environment temperature and energy utilize purpose.Therefore, phase-changing energy storage material is applied in the concrete flag design, utilize the exothermic effect of liquid phase-change energy storage material in liquid-solid phase transition process, play the effect of snow melt deicing preferably, the application of this material system can effectively promote the antifreeze anti-slide performance of road slab, reduce accident rate.
Current, the application of phase-changing energy storage material in construction work mainly concentrates on the heating of the heat-insulating energy-saving mortar of architectural exterior-protecting construction, various sheet material, member, indoor floor etc., provide a kind of energy storage materials of phase change composite plate that contains as Chinese utility model patent ZL 200820035123.9, had heat preservation and energy conservation effects preferably; Utility model patent ZL 200620165844.2 provides a kind of phase-change material accumulation of energy floor heating device, can be as required carries out the heat release heating to indoor.This shows that the application of phase-changing energy storage material can realize the intelligent adjustable of temperature preferably, meet the development trend of current energy-saving and environmental protection building materials.
The utility model content
The purpose of this utility model be to overcome the deficiencies in the prior art and a kind of intelligent degree height is provided, need heat, the antifreeze antiskid concrete flag that contains phase-changing energy storage material of antifreeze antiskid, environmental protection, this road slab structure is incorporated into the phase-changing energy storage material system in the concrete flag design, improves the antifreeze cling property of road slab by phase transformation heat release function.
To achieve these goals, the technical solution of the utility model is: a kind of antifreeze antiskid concrete flag that contains phase-changing energy storage material, comprise main body concrete structure layer and antiskid concrete surface layer, be provided with the stainless steel hollow section layer that contains phase-changing energy storage material between described main body concrete structure layer and the antiskid concrete surface layer.
In the utility model, the described stainless steel hollow section layer that contains phase-changing energy storage material is made of fluid concrete on the stainless steel hollow section of even setting, is sealed with phase-changing energy storage material in the described stainless steel hollow section.
In the utility model, the described stainless steel hollow section layer that contains phase-changing energy storage material is apart from road slab surface 3～5cm, described hollow section external diameter 4～6cm.
In the utility model, the distance between the described hollow section of two adjacent tubes is 1～2 times of outer diameter of steel pipes.
The utility model has adopted the gradient method for designing, and traditional Cement Concrete Pavement Slab is carried out hierarchical design, is divided into the main body concrete structure layer of bottom, stainless steel hollow section layer and the surperficial antiskid layer of concrete that the centre contains phase-changing energy storage material.Phase-changing energy storage material normal temperature in the middle stainless steel hollow section is down for liquid, liquid-solid phase transition temperature scope is 6～10 ℃, in phase transition process, material is emitted heat, be transmitted to road crust, effectively prevent and delay process icy on road under the sleet freezing weather, simultaneously, under the table antiskid layer comprehensive function of road, effectively promoted the antifreeze cling property of concrete flag.Compared with prior art, show following advantage: (1) compares traditional snow melt deicing technology, and the heat release of phase-changing energy storage material has intelligent degree height, need not heat plurality of advantages such as energy-saving and environmental protection, and favorable repeatability.
