Abstract
The utility model relates to a kind of steel strand for hot melt anchor, belongs to basic technical field of fixed buildings.These steel strand being used for hot melt anchor comprise steel wire core and insulated cladding, and steel wire core is the steel wire of sub-thread or strands, are embedded with the wire extended along steel wire core length direction in insulated cladding.These steel strand for hot melt anchor have and can be connected with the electric heater unit on ground tackle by wire easily when not affecting existing steel strand performance, can realize by wire energising, electric heater unit being generated heat, the sheath of hot melt ground tackle can be made to soften or fusing, the frictional resistance reducing or relieve between core and clip assemblies, thus reach the convenient object reclaiming steel strand.
Description
Technical field
The utility model relates to a kind of steel strand, belongs to basic technical field of fixed buildings.
Background technology
Presstressed reinforcing steel (as reinforcing bar, steel strand or steel wire etc.) is widely used in existing prestressed reinforced concrete construction or geotechnical engineering structure, the above-mentioned presstressed reinforcing steel as main bearing member all will be used and can keep its pulling force and by pull transfer to the anchor device in concrete or ground, this anchor device is referred to as use for tendon ground tackle.Use for tendon ground tackle mainly contains the formula of bonding, supporting type, male cone type and clip type four class ground tackle.
Presstressed reinforcing steel is all single use usually, and uses and be all retained in (its length can reach 20-30 rice) in concrete or rock-soil layer afterwards.So, not only waste material, also obstacle is formed to adjacent structure construction.In considerable case history, adjacent structure in follow-up construction because the impact of reinforcing bar, steel strand or steel wire, have to take special working measure, process difficulty and the expense of underground obstacle when considerably increasing exploitation, therefore need to reclaim presstressed reinforcing steel.
Reclaim to realize steel strand, the application number of applicant's application is: the strand tapered anchorage of a kind of improvement of CN201310086728.6, when needs reclaim steel strand, wire can be utilized to be energized makes electric heater unit generate heat, sheath can be made to soften or fusing, thus the frictional resistance reducing or relieve between core and clip assemblies, reach the convenient object reclaiming steel strand.
But find when applicant uses, wire and steel strand are two separate respectively lines; in engineering construction; wire connects inconvenience with the electric heater unit on ground tackle, and the protection simultaneously for wire in construction can not put in place, can not meet the energising needs of hot melt anchor.
Utility model content
The technical problems to be solved in the utility model is not enough for prior art, proposes a kind of steel strand for hot melt anchor that wire can be facilitated when not affecting existing steel strand performance to connect with the electric heater unit on ground tackle.
The utility model is the technical scheme solving the problems of the technologies described above proposition: a kind of steel strand for hot melt anchor, comprise steel wire core and insulated cladding, described steel wire core is the steel wire of sub-thread or strands, is embedded with the wire extended along described steel wire core length direction in described insulated cladding.
The utility model by being embedded with the wire extended along steel wire core length direction in insulated cladding, easily wire can be connected with the electric heater unit on ground tackle when not affecting existing steel strand performance, can realize by wire energising, electric heater unit being generated heat, the sheath of hot melt ground tackle can be made to soften or fusing, the frictional resistance reducing or relieve between core and clip assemblies, thus reach the convenient object reclaiming steel strand.Meanwhile, two wires are embedded in insulated cladding, can protect wire.
The improvement of technique scheme is: the lateral wall of described insulated cladding is shaped with the raised line extended along described steel wire core length direction, and described wire is located in raised line.
The improvement of technique scheme is: be filled with anticorrosion grease between described steel wire core and insulated cladding.
The improvement of technique scheme is: described wire is enamel-covered wire.
The improvement of technique scheme is: described insulated cladding is PE insulated cladding.
The improvement of technique scheme is: described wire is two wires extended along described steel wire core length direction.
The improvement of technique scheme is: described raised line is a raised line extended along described steel wire core length direction, and two wires are located in a raised line.
The improvement of technique scheme is: described raised line is two raised lines extended along described steel wire core length direction, and two raised lines are oppositely arranged, and are provided with a wire in every bar raised line.
The utility model is oppositely arranged by two raised lines, is provided with a wire in every bar raised line, and like this, wire is oppositely arranged on the both sides of steel wire core, when using steel strand of the present utility model, can prevent wire clot, destroys insulated cladding.
The improvement of technique scheme is: described wire is four wires extended along described steel wire core length direction.
