Detailed description of the invention
Be described principle of the present invention and feature below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit scope of the present invention.
Embodiment of the present invention technical problem to be solved is traditional prestress anchorage cable is single use, not only causes the waste of material, also increases the development obstacles of the adjacent underground space, strengthens difficulty of construction.
As shown in Figure 1, Figure 2 and Figure 3, be a kind of hot melt self-tipping type anchor head schematic diagram for reclaiming anchor cable that the embodiment of the present invention provides, it comprises:
Outer anchor body 1, described outer anchor body is provided with at least one half anchor hole (i.e. half anchor hole 11 of outer anchor body); As shown in Figure 4, Figure 5, Figure 6 and Figure 7.
Interior anchor post 2, described interior anchor post is provided with at least one half anchor hole (i.e. half anchor hole 21 of interior anchor ring); Interior anchor post is arranged in described outer anchor body, and half anchor hole of outer anchor body forms anchor hole with half anchor hole of corresponding interior anchor post; Described interior anchor post is made up of low melting material; As shown in Figure 8, Figure 9, Figure 10 and Figure 11.
Electric heater unit 4, is arranged on described interior anchor body inner, low melting material can be made to melt; The fusing point of described low melting material is between 100 DEG C ~ 120 DEG C; In specific implementation process, low melting material is the epoxy resin of hot melt character.As shown in Figures 2 and 3.
Intermediate plate 3, described intermediate plate is arranged in described anchor hole;
Described steel strand penetrate described intermediate plate, and described in tractive, during steel strand, frictional force provides the tensioning fixation power of intermediate plate, and intermediate plate is automatically locked by anchor post in extruding.
The present invention is as follows for the assembling and use procedure of reclaiming the hot melt self-tipping type anchor head of anchor cable:
During assembling, interior anchor post opsition dependent is put into outer anchor body, half anchor hole of outer anchor body forms anchor hole with half anchor hole of corresponding interior anchor post, and interior anchor post is bound in a relatively airtight space, and when Shi Hanzhang, it is stressed more reasonable.In interior anchor post, be also provided with electric heater unit, wire is drawn outside seal closure, so that internal anchor post heats when reclaiming prestress anchorage cable.
After completing above-mentioned steps, penetrate steel strand, pass after outer anchor body certain length until steel strand, in the taper hole in the middle of steel strand, outer anchor body, interior anchor post, put into intermediate plate, like this when applying pulling force to steel strand, steel strand, intermediate plate, outer anchor body and interior anchor post can mutual jam-packeds; The pulling force of steel strand applying is converted into the frictional force of steel strand and intermediate plate inside, then is converted into the pressure of intermediate plate and interior anchor post, then be delivered to base plate, be finally delivered on cement slurry, be delivered in surrounding soil by the friction between cement slurry and the soil body.Outside ground tackle, through the steel strand outsourcing rubber sleeve of anchor hole, steel strand and cement paste are isolated, and steel strand are coated with one deck grease outward, to reduce the frictional force of itself and rubber sleeve, so that the corresponding reduction of recovery power when reclaiming steel strand.
During recovery prestress anchorage cable, internal anchor post heats, and the heat of electric heater unit release makes interior anchor post melt, and then intermediate plate launches, and the frictional force of steel strand and intermediate plate disappears, and can facilitate, reclaim steel strand easily.
State on the invention for reclaiming in the hot melt self-tipping type anchor head of anchor cable, one end to the other end of described anchor hole is diminishing structure; Described clamping piece structure and described anchor hole structure suitable and be arranged in described anchor hole.One end of described anchor hole is diminishing structural form and frustoconical construction to the other end, is convenient to intermediate plate and moves in anchor hole, forms the power of clamping steel strand.
Stating on the invention for reclaiming in the hot melt self-tipping type anchor head of anchor cable, there is the problem that cement paste enters anchor head in use, the cement solidified increases the frictional force between outer anchor body, interior anchor ring, intermediate plate, affects the recovery of steel strand.Improve further above-described embodiment, hot melt self-tipping type anchor head also comprises seal closure, and described seal closure covers described outer anchor body and interior anchor post, is connected with the sealed bottom of described outer anchor body.Be buckled in by seal closure on base plate, the two is fixedly connected with (as welding), in case cement paste enters anchor head, thus affects the recovery of anchor cable.
State on the invention for reclaiming in the specific implementation process of hot melt self-tipping type anchor head of anchor cable, described outer anchor body 1 comprises 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 half anchor holes be arranged symmetrically with along ring central axis (being illustrated in figure 4 4); The welded top of described top board and described outer anchor ring, the bottom welding of described base plate and described outer anchor ring; Top board, base plate are provided with the perforate (perforate 51 of top board, the perforate 61 of base plate) corresponding with half anchor hole position of outer anchor ring.Outer anchor ring is made by steel, and itself and top board, base plate form the chamber of a relative closure, so that anchor post in loading, during Shi Hanzhang, interior anchor post is in the state of three-dimensional pressurized, and its modulus is increased, and reduces distortion.
State on the invention for reclaiming in the specific implementation process of hot melt self-tipping type anchor head of anchor cable, described electric heater unit is connected with control member, power supply by wire, and whether control member works for controlling electric heater unit; Power supply provides the energy for electric heater unit.When pending prestress anchorage cable reclaims, energising makes electric heater unit heat, and interior anchor post is melted, and intermediate plate comes off, and reclaims steel strand.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
