Description
Technical field
The utility model relates to a kind of concrete component, particularly a kind of high permanent seal cooling concrete structure member.
Background technology
How effectively to prevent corrosion of steel bar from being a great problem that in corrosive environment, (as in coal industry environment and marine environment) reinforced concrete structure faces.Corrosion of steel bar has become the main disaster causing global concrete steel building durability deficiency, premature failure.For many years, the accident that coastal building causes because durability is bad happens occasionally, and the economic loss brought thus and consolidation process expense constantly increase.There is a large amount of reinforced concrete structure to cause concrete cracking by corrosion of steel bar at present, sag of protecting coating and the event that causes is a lot, make its service life far below design load or desired value.Domestic and international statistics shows, the economic loss number that corrosion of steel bar causes structural failure to cause is surprising.China, the problem caused by corrosion of steel bar is in recent years very serious, such as Ministry of Communications once did investigation in 1996 to the destruction situation of China's port works concrete structure, result shows, 80% structure occurs seriously or more serious corrosion of steel bar destroys, and occurs that the time of corrosion and destruction only has 5 years; Railway autumn in 1994 inspection statistics is pointed out, what in Railway Concrete Bridge, have disease has 2675, and what corrosion of steel bar damage wherein occurred has 722, accounts for 27%.
Fiber composite reinforcing material replaces the better selection of reinforcing bar under progressively becoming corrosive environment owing to having good decay resistance, but the mechanical property difference between fiber composite reinforcing material and reinforcing bar is larger, fiber composite reinforcing material is a kind of linear elastic materials, its curves of stress-strain relationship is not similar to the same yield point of reinforcing bar, the damage-form of therefore joining the concrete structure member of fiber composite reinforcing material muscle shows as crushing of concrete or fiber composite reinforcing material muscle and breaks and all belong to brittle fracture, and a kind of damage-form that brittle fracture is engineering structures must be avoided.
Existing problems: (1) ordinary reinforced concrete structure component is due to concrete cover to reinforcement finite thickness, and reinforcing bar is easy to corrosion, thus cause the durability of structure not enough.(2) traditional ductility of joining the concrete structure member of fiber composite reinforcing material muscle is poor, and structure very easily brittle fracture occurs.
Utility model content
The purpose of this utility model to provide a kind of high permanent seal cooling concrete structure member, the problem of the brittle fracture of the corrosion of steel bar faced with existing reinforced concrete structure under solving corrosive environment and the concrete structure member of joining fiber composite reinforcing material muscle.
The purpose of this utility model is achieved in that high permanent seal cooling concrete structure member of the present utility model, comprises fiber composite reinforcing material and indulges muscle, fiber composite reinforcing material cloth, shaped steel, concrete and polyurea elastomer; The periphery of indulging muscle at fiber composite reinforcing material is wound around fiber composite reinforcing material cloth, forms fiber composite reinforcing material cage, arranges shaped steel in the inside of fiber composite reinforcing material cage; Adopt concrete parcel fiber composite reinforcing material cage and shaped steel; Polyurea elastomer is provided with at the external surface of concrete integument.
Described fiber composite reinforcing material is indulged muscle and is many, and is parallel to each other.
Described fiber composite reinforcing material is carbon fiber composite reinforced material, alkali resistant fiberglass composite reinforced material, aramid fiber composite reinforcing material or basalt fibre composite reinforcing material.
Described shaped steel is steel flanged beam shaped steel or lattice shaped steel.
The described staggered form that is wound up as is wound around or unidirectional winding.
Beneficial effect, the utility model is by adopting fiber composite reinforcing material to replace reinforcing bar and improving the durability of structural element in structural element surface spraying polyurea elastomer, place by inside concrete the ductility that shaped steel improves structural element, thus ensureing that the prerequisite of component ductility is issued to the object of component high-durability.Compared with prior art there is following advantage:
1) high-durability.Adopt fiber composite reinforcing material to replace reinforcing bar and ensure the high-durability of structural element in structural element surface spraying polyurea elastomer.
2) high ductility.Be furnished with shaped steel in the core of component, ensured the ductility of structural element by the good distortion of steel.Shaped steel has enough thickness of concrete cover because it is positioned at the core of structural element simultaneously, thus can exempt from corrosion.
3) good economy and processing characteristics.Adopt overall fiber composite reinforcing material cloth to be wrapped in the periphery that muscle indulged by fiber composite reinforcing material, its quick construction is convenient, saves because stirrup joint too much wastes material.Simultaneously fiber composite reinforcing material cloth easily bends, the problem that when avoiding the stirrup brake forming of fiber composite reinforcing material, intensity is significantly degenerated, thus can give full play to the mechanical property of material.
