Abstract
The utility model relates to a high-amplitude steel strand group anchor inhaul cable which is composed of clamping pieces, an anchor plate, a supporting cylinder, nuts, a connecting cylinder, a cable body, etc., wherein the cable body comprises a plurality of steel strands for connecting a horn sleeve cylinder between the anchor plate and the connecting cylinder, mortar poured in the horn sleeve cylinder is wrapped with the steel strands which pass through the horn sleeve cylinder, the steel strands are clamped by the gripping and wrapping force which is generated by an anchoring unit and the mortar in the horn sleeve cylinder, and the anchoring unit is composed of the clamping pieces and the anchor plate. The fatigue load stress amplitude of the utility model can reach 250MPa, and the utility model has good anchoring performance under low stress.
Description
The utility model belongs to a kind of large span member (as cable stayed bridge etc.) load-bearing steel strand group anchor cable.
Existing steel strand group anchor cable anchoring property under low-stress state is not so good, and the amplitude of stress that drag-line can only bear fatigue loading is below the 200Mpa, can not satisfy big amplitude of stress bridge and use, and the antiseptic property of drag-line and durability are also not so good in addition.
It is 250Mpa that the purpose of this utility model is to provide a kind of fatigue loading amplitude of stress of bearing, the high amplitude steel strand group anchor cable that anchoring property is good under the low-stress state.
For achieving the above object, solution of the present utility model is to be provided with the loudspeaker sleeve in the anchor slab rear end, the front end of loudspeaker sleeve is placed between anchor slab and the carrying cylinder, screw rod passes anchor slab and the loudspeaker sleeve is tightened on the carrying cylinder, with the nut rotation set on carrying cylinder, the mortar that the filling of loudspeaker barrel bore has is bundled together with the steel strand that pass the loudspeaker sleeve, and the rear end of loudspeaker sleeve links to each other with connecting cylinder.The bond stress that anchoring unit that is made of intermediate plate, anchor slab and the mortar in the loudspeaker sleeve produce clamps steel strand, then power is delivered on carrying cylinder and the nut, by nut power is delivered on the member again.
Because the utility model is provided with the loudspeaker sleeve in the anchor slab rear end, and filling has mortar in the loudspeaker sleeve, the bond stress that mortar and steel strand produce in the loudspeaker sleeve, can bear 50% dynamic loading, amplitude of stress can reach 250Mpa when this drag-line bearing load was limited to 0.45 times of cable body steel strand Fracture Force on stress, anti-fatigue performance is further enhanced, the bridge that can satisfy big amplitude of stress uses, its intermediate plate is good from the anchor performance under low-stress state, steel strand have good antiseptic property and durability, and the drag-line appearance looks elegant is generous.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1--be structural representation of the present utility model.
Fig. 2--be the schematic diagram of the intermediate plate of Fig. 1.
As Fig. 1, shown in Figure 2, steel strand group anchor cable provided by the utility model partly is made up of drag-line part and group's anchor ground tackle, drag-line partly comprises the cable body 14 that is made of some steel strand, pre-pipe laying 8, connecting cylinder 9, damping device 10, transition conduit 11, parrel 12, group's anchor ground tackle partly comprises intermediate plate 3, anchor slab 4, carrying cylinder 5, nut 6, some taper holes that are circle distribution are arranged on the anchor slab 4, intermediate plate 3 is housed in the taper hole, the steel strand that pass taper hole tightly are clamped on the anchor slab 4 by intermediate plate 3, the outer cone gradient α that cooperates with anchor slab 4 taper holes of intermediate plate 3 is 5 °-7 °, the interior sound of baby talk type that intermediate plate 3 contacts with steel strand is that closely-pitched falls sawtooth pattern, tooth is apart from the t=0.5-1.5 millimeter, and intermediate plate 3 length are the 40-60 millimeter.Be equipped with by pressing plate and be loaded on the intermediate plate locking device 1 that every steel hinge line upper spring is formed at anchor slab 3 front ends; can prevent because the intermediate plate that a variety of causes causes is loosening and keeping clip effectively follows up; ground tackle protective cover 2 is linked to each other with nut 6, fill with cement mortar or epoxy mortar in the protective cover 2.Be provided with loudspeaker sleeve 7 in anchor slab 4 rear ends, loudspeaker sleeve 7 front ends are placed between anchor slab 4 rear ends and the carrying cylinder 5, screw rod passes anchor slab 4 and loudspeaker sleeve 7 front ends are tightened on the carrying cylinder 5, with nut 6 rotation sets on carrying cylinder 5, loudspeaker sleeve 7 inner chambers are irritated cement mortar or the epoxy mortar that has and the steel strand that pass loudspeaker sleeve 7 are bundled together, by intermediate plate 3, the bond stress that anchoring unit that anchor slab 4 constitutes and the cement mortar in the loudspeaker sleeve or epoxy mortar produce tightly clamps steel strand, part power on the steel strand can be delivered on carrying cylinder 5 and the nut 6 by loudspeaker sleeve 7, power is delivered on the member of bridge floor by nut 6, loudspeaker sleeve 7 links to each other with connecting cylinder 9 again.The pre-pipe laying 8 that is arranged on outside loudspeaker sleeve 7 and the connecting cylinder 9 is connected on nut 6 and the transition conduit 11, damping device 10 is installed between pre-pipe laying 8 exits and the connecting cylinder 9, be used to absorb or eliminate various vibrations from cable body 14, to reduce since vibration to the influence of anchoring unit anchoring property.Transition conduit 11 links to each other with connecting cylinder 9, and cable body 14 is combined by the low loose steel strand of 7-127 high strength, and they pass the taper hole of transition conduit 11, connecting cylinder 9, loudspeaker sleeve 7 and anchor slab 4, tightly are clamped on the anchor slab 4 by intermediate plate 3.Every steel strand are behind parcel paraffin wax layer or anticorrosion oil layer, double wrapped HDPE sheath again, antiseptic property with further raising steel strand, cable body outside the transition conduit 11 14 is put parrel 12, make the steel strand combination bunchy outside transition conduit 11, cable body 14 skins are with HDPE sleeve pipe 13, and the color of this sleeve pipe 13 is optional black, yellow, blue, orange etc.
