Description
Technical field:
The utility model relates to a kind of anchor cable, particularly a kind of recyclable type anchor cable.
Background technology:
Development along with modern building technology, urban construction is constantly to highrise building and underground space development, both need the infrastructure space equally, thereby can not cross the construction red line as building facilities and invade other underground space, the cable body steel strand of foundation ditch cable bolting are reclaimed the needs that embodied urban construction, also meet environmental protection requirement.
Existing domestic and international recyclable anchor cable system all exists cable body complex structure, cost recovery problem of higher; The recyclable anchor cable of U type as Japan, patent announcement number is: " the recoverable prestress anchorage cable " of CN200964593Y all is to adopt U type supporting body structure, its U type supporting body complex structure, cost of manufacture is very high, after steel strand are made the U type, influenced the intensity of steel strand itself, the reduction of having to is used, this has also increased the cost of cable body, and reclaim the back steel strand and be wavy, can not recover the original wire of steel strand, thereby steel strand can not reuse, Figure 11-13 represents a kind of structural representation with recyclable anchor cable of U type supporting body structure.
The utility model content:
The technical problems to be solved in the utility model is: a kind of recyclable type anchor cable simple in structure is provided, it can guarantee the prestressed realization of anchor cable reliably, when needs carry out the recovery of anchor cable cable body, the cable body steel strand can be pressed release the ground tackle from allowing again, steel strand are returned from the soil body, to solve problems such as complex structure, cost of manufacture that the recyclable anchor cable of above-mentioned existing U type exists are very high, steel strand can not be reused.
The technical scheme that solves its above-mentioned technical problem is: a kind of recyclable type anchor cable, comprise outer anchor head part and interior anchoring section, should comprise anchor cable cable body and multilevel cable body bearing structure by interior anchoring section, described bearing structure at different levels by allow press ground tackle or allow press that ground tackle and bearing plate form allow the pressure bearing structure, the first order of cable body allows presses bearing structure to press ground tackle I and bearing plate to form by allowing, all the other are at different levels to allow and presses bearing structure or only press ground tackle II to form or by allowing pressure ground tackle II and bearing plate form jointly by allowing, one end of each root presstressed reinforcing steel of described formation anchor cable cable body be anchored on the bearing plate I by to be allowed the extruded sleeve and the anchoring medium extruding of pressing ground tackle I respectively, allow press ground tackle I allow pressure point greater than allowing the pressure point that allows of pressing ground tackle II, that is: allow and press slip pulling force that ground tackle I bears greater than allowing the slip pulling force of pressing ground tackle II to bear.
Its further technical scheme is: each root presstressed reinforcing steel length of described formation anchor cable cable body all equates, allow on every presstressed reinforcing steel and press bearing structure quantity identical.
Its again further technical scheme be: described allowing presses ground tackle to comprise extruded sleeve and anchoring medium, and extruded sleeve and anchoring medium extruding are anchored to form on the presstressed reinforcing steel and allow the pressure ground tackle; Described anchoring medium is that cross section is a spring wire witha circular; Described presstressed reinforcing steel or steel strand or steel tendon, or have the unbonded tendon of sleeve pipe, this unbonded tendon is made by steel strand or steel tendon.
The bearing structures at different levels of the recyclable type anchor cable of the utility model all by allow press ground tackle or allow press that ground tackle and bearing plate form allow the pressure bearing structure, allow and press ground tackle to comprise extruded sleeve and anchoring medium, extruding by the extruding facility, the extruding of extruded sleeve and anchoring medium is anchored at formed one on the presstressed reinforcing steel and allow the pressure ground tackle, it allows the press reason be: externally under the tension, relatively do constant force and slide by anchoring medium and extruded sleeve under certain pulling force for presstressed reinforcing steel, extruded sleeve and anchoring medium play the anchoring effect to presstressed reinforcing steel when being lower than this value of thrust, and presstressed reinforcing steel does not slide.When presstressed reinforcing steel was done the constant force slip, anchoring medium was not damaged presstressed reinforcing steel, does not influence its mother metal performance.
Because the anchor cable cable body of the recyclable type anchor cable of the utility model is made up of many presstressed reinforcing steels of equal in length; Described bearing structure at different levels all is to allow the pressure bearing structure, first order bearing structure is to allow press ground tackle I and bearing plate to form, all the other are at different levels to allow and presses bearing structure or only press ground tackle II to form or by allowing pressure ground tackle II and bearing plate form jointly by allowing, allow and press ground tackle under design stress, the anchored force to the anchor cable presstressed reinforcing steel steadily to discharge, presstressed reinforcing steel slides allowing press in the ground tackle, thereby make the stressed automatic distribution of each grade bearing structure, whole stress is even, can reliably guarantee the prestressed realization of anchor cable.During design, make to allow and press that ground tackle I's allow pressure point greater than allowing the pressure point that allows of pressing ground tackle II, that is: make to allow and press slip pulling force that ground tackle I bears greater than allowing the slip pulling force of pressing ground tackle II to bear, thereby guarantee when needs carry out the recovery of anchor cable cable body, applying greater than allowing presses ground tackle I allow the pulling force of pressure point, just the cable body presstressed reinforcing steel can be pressed release the ground tackle from allowing, the cable body presstressed reinforcing steel is returned from the soil body, so that use next time.Thereby, have following beneficial effect:
1, adopt the recyclable system of single presstressed reinforcing steel, many presstressed reinforcing steels can be assembled flexibly, and easy to make, cost is low.
2, each root presstressed reinforcing steel length of anchor cable is the same, and cable body stress is more even, and is stressed reliable.
But 3 integral tensions, single tension are to value of thrust, and it is more easy to construct.
4, adopt the single pressure ground tackle that allows, release is simple, reclaims reliable.
5, reclaiming the back presstressed reinforcing steel can reuse, and does not influence its mother metal performance.
Be further described below in conjunction with the technical characterictic of drawings and Examples the recyclable type anchor cable of the utility model.
