Abstract
The utility model provides a yielding device used in anchoring, is mainly used for safe anchoring in geotechnical engineering, and can be used with an anchor rod or an anchor cable or used independently in underground roadway supporting. The yielding device is characterized in that the conical head on a rod body is stepped and is matched with an anchor pipe; and the anchor pipe adopts a pipe body with screw threads. The utility model has the beneficial contributions that as the conical head on the rod body is stepped and is matched with the anchor pipe, when the anchor rod is used in geotechnical anchoring, and pressure is suddenly exerted on a rock formation, the conical head moves in the anchor pipe in such a manner that the conical head is rubbed against the anchor pipe, and the yielding effect is achieved. The utility model protects the anchor rod from being damaged, and improves the performance of safe use.
Description
(1) technical field: the utility model be a kind of anchoring with allowing pressure device, be mainly used in the anchoring of geotechnical engineering safety, can cooperate anchor pole or anchor cable to be used in the underworkings supporting, also can be used in the underworkings supporting separately.It belongs to the anchoring of geotechnical engineering support anchor rod with allowing pressure device.
(2) background technology: the anchor pole that geotechnical engineering is used for anchoring be by metallic rod body, resin anchoring agent or cement anchoring agent, special nut, pallet is supporting forms.Its metallic rod body is by low vertical muscle or not have vertical muscle screw-thread steel be that mother metal is made, and it is made of the thread segment of body of rod section of anchoring into and afterbody top nut.When the geotechnical engineering anchoring construction, anchor pole section of anchoring into and rock stratum are through the bonding formation one of anchoring agent, and the thread segment of process anchor bar body afterbody and nut make pallet exert pressure to rock layer surface and form anchoring again.Because anchor pole section of anchoring into and rock stratum are through the bonding formation one of anchoring agent, the thread segment of process anchor bar body afterbody and nut make pallet exert pressure to rock layer surface and form anchoring again, thereby anchor pole pressurized multiplication when the rock stratum is pressed suddenly certainly will cause the anchor pole damage anchoring accident to occur.
(3) summary of the invention: the purpose of this utility model mainly adopts a kind of anchoring with allowing the pressure device design, and the rock stratum is pressed the problem that makes the anchor pole damage suddenly when solving anchoring, improves the safety in utilization of anchor pole.
A kind of anchoring described in the utility model is with allowing the design scheme of pressure device be: it is made of conehead on the body of rod and the body of rod and anchor tube.Be characterized in: the conehead on the body of rod is step and cooperates with anchor tube, and its anchor tube is the body that has spiral lamination, and the spiral lamination that anchor tube has is left-handed, also dextrorotation.
Originally make real novel described a kind of anchoring with allowing pressure device compared with prior art, its useful contribution is to cooperate with anchor tube owing to the conehead on the body of rod is step, make anchor pole rock stratum in ground anchorage press the back conehead in anchor tube, to grind difference suddenly and move the pressure effect that allows of playing, make anchor pole injury-free, improve safe application performance.
(4) description of drawings: Fig. 1 is the utility model schematic diagram.
(5) specific embodiment: 1 pair of a kind of anchoring of the present utility model is as follows with allowing pressure device be further described in conjunction with the accompanying drawings: a kind of anchoring described in the utility model with allow pressure device be by on the body of rod 1 and the body of rod conehead 2 and anchor tube 3 constitute, conehead 2 is step and cooperates with anchor tube 3, anchor tube 3 is the bodys that have spiral lamination, the spiral lamination that anchor tube has is left-handed, also dextrorotation.
Claims (2)
- An anchoring with allow pressure device by on the body of rod and the body of rod conehead and anchor tube constitute, it is characterized in that: conehead is step and cooperates with anchor tube, anchor tube is the body that has spiral lamination.
- 2. a kind of anchoring according to claim 1 is characterized in that with allowing pressure device: the spiral lamination that anchor tube has is left-handed, also dextrorotation.
