In the outer anchor body, half anchor hole of outer anchor body forms anchor hole with half anchor hole of corresponding interior anchor post；The interior anchor post is by low melting point
Material is made；As shown in Figure 8, Figure 9, Figure 10 and Figure 11.
Electric heater unit 4, inside the interior anchor post, melts can low melting material；The low melting material
Fusing point between 100 DEG C～120 DEG C；In specific implementation process, low melting material is the epoxy resin for heating property.As schemed
Shown in 2 and Fig. 3.
Intermediate plate 3, the intermediate plate is in the anchor hole；
The steel strand wires penetrate the intermediate plate, and when pulling the steel strand wires, frictional force provides the tensioning fixation power of intermediate plate, folder
Piece is locked automatically by anchor post in extruding.
The present invention is used for the assembling of the hot melt self-tipping type anchor head for reclaiming anchor cable and uses process as follows：
During assembling, interior anchor post opsition dependent is put in outer anchor body, half anchor of half anchor hole of outer anchor body and corresponding interior anchor post
Hole forms anchor hole, and interior anchor post is bound in a relatively closed space, and when prestressing force is applied, its stress is more
Rationally.Electric heater unit is additionally provided with interior anchor post, wire is drawn outside seal closure, internal during prestress anchorage cable to reclaim
Anchor post is heated.
After completing above-mentioned steps, steel strand wires are penetrated, after steel strand wires pass outer anchor body certain length, in steel strand wires, outer anchor
Intermediate plate is put in taper hole in the middle of body, interior anchor post, so when pulling force is applied to steel strand wires, steel strand wires, intermediate plate, outer anchor body and interior
Anchor post can mutual jam-packed；Frictional force inside steel strand wires and intermediate plate is converted into the pulling force that steel strand wires apply, intermediate plate is then converted to
With the pressure of interior anchor post, then base plate is delivered to, is eventually transferred on cement slurry, by the friction between cement slurry and the soil body
It is delivered in surrounding soil.Outside anchorage, through the steel strand wires outsourcing rubber sleeve of anchor hole, steel strand wires are made to isolate with cement mortar, steel
Twisted wire applies outward one layer of grease, to reduce its frictional force with rubber sleeve, accordingly reduces in order to reclaim recovery power during steel strand wires.
When reclaiming prestress anchorage cable, internal anchor post is heated, and the heat of electric heater unit release makes interior anchor post fusing, enters
And intermediate plate launches, steel strand wires are disappeared with the frictional force of intermediate plate, can be facilitated, easily be reclaimed steel strand wires.

Tapered little structure；The clamping piece structure is adapted with the anchor hole structure and is arranged in the anchor hole.The one of the anchor hole
It is diminishing structural form i.e. frustoconical construction to hold to the other end, is easy to intermediate plate to move in anchor hole, is formed and clamps steel strand wires
Power.
In the above-mentioned hot melt self-tipping type anchor head for reclaiming anchor cable of the present invention, using when there is cement mortar and enter anchor head
Problem, the cement of solidification increases outer anchor body, the frictional force between interior anchor ring, intermediate plate, affects the recovery of steel strand wires.To above-mentioned
Embodiment is further improved, and hot melt self-tipping type anchor head also includes seal closure, and the seal closure covers the outer anchor body and interior anchor post,
It is connected with the sealed bottom of the outer anchor body.Seal closure is buckled on base plate, the two is fixedly connected（As welded）, in case cement mortar
Anchor head is entered, so as to affect the recovery of anchor cable.
In the above-mentioned specific implementation process of hot melt self-tipping type anchor head for reclaiming anchor cable of the present invention, the outer anchor body 1
Including outer anchor ring 12, top board 5 and base plate 6, as shown in Figure 12 and Figure 13；The inwall of outer anchor ring has several along ring central shaft pair
Claim half anchor hole of arrangement（It is illustrated in figure 44）；The welded top of the top board and the outer anchor ring, the base plate with described
The bottom welding of outer anchor ring；Top board, base plate are provided with perforate corresponding with half anchor hole position of outer anchor ring（The perforate 51, bottom of top board
The perforate 61 of plate）.Outer anchor ring is made by steel, and which constitutes the chamber of a relative closure with top board, base plate, so as to anchor in loading
Post, applies interior anchor post during prestressing force and is in three-dimensional pressurized state so as to which modulus increases, and reduces deformation.
In the above-mentioned specific implementation process of hot melt self-tipping type anchor head for reclaiming anchor cable of the present invention, the electrical heating dress
Put and be connected with control piece, power supply by wire, control piece is used for controlling whether electric heater unit works;Power supply is electric heater unit
The energy is provided.When pending prestress anchorage cable is reclaimed, being powered heats electric heater unit, interior anchor post fusing, intermediate plate is come off, is returned
Receive steel strand wires.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all spirit in the present invention and
Within principle, any modification, equivalent substitution and improvements that is made etc. should be included within the scope of the present invention.
