Abstract
The utility model relates to an opposite pulling anchor rod device for limiting the lateral deformation of a masonry wall body. The opposite pulling anchor rod device comprises an anchor rod body, an inner side tray and an outer side tray, wherein the anchor rod body passes through a pre-limited masonry wall body, the inner side tray and the outer side tray are respectively arranged at two sides of the pre-limited masonry wall body, screw nuts for fixing the outer side tray are arranged at the outer side of the outer side tray, the outer sides of the inner tray and the outer tray are respectively provided with wear reduction gaskets, the inner side end part of the anchor rod body is a T-shaped pier head, and the outer side end part is provided with a thread rolling section. Through preserving holes arranged on the masonry wall body, the anchor rod body penetrates through the masonry wall body, the outer side tray, the wear reduction gaskets and the screw nuts are respectively arranged on the outwards exposed thread rolling section, then, the screw nuts are tightly screwed through a torque spanner, the required moment value is reached, the two-end clamping anchoring structure is formed, the bonding damage failure of anchoring agents caused by great deformation of surrounding rock can be avoided, the structure of the opposite pulling anchor rod device is simple, and the effect is good.
Description
Technical field
The utility model relates to a kind of to drawing the anchor pole device, especially a kind of restriction masonry panel lateral deformation that is applicable to ground, roadway, construction of tunnel basis usefulness to drawing the anchor pole device.
Background technology
In order to satisfy mine ventilation, to produce and to take over and the needs of gas control, usually can construct some bodies of wall in the coal mining, the tunnel remained along the goaf, as the stope drift active workings of next work plane at mining face rear.Stay the body of wall of establishing behind these goafs, should bear strong mining influence during this working face extraction, experience the mining influence of follow-up adjacent work plane again, cause the drastic deformation of masonry panel to destroy, must add strong supporting masonry panel.Though conventional bolt support has certain effect, because masonry panel thickness is little, deflection is big; Be easy to cause the bond-anchorage section of anchor pole to destroy; Can't form stable anchoring basic point, cause anchorings such as sliding anchor, slip to lose efficacy immalleable long-term large deformation condition; In order to improve the stability that masonry panel carries under mining induced stress effect repeatedly, must explore novel bolt support structure and satisfy this type large deformation, control needs of masonry panel under the mining pressure condition by force.
Summary of the invention
The purpose of the utility model is the weak point that overcomes in the prior art, provide a kind of simple in structure, effective restriction masonry panel lateral deformation to drawing the anchor pole device.
For realizing above-mentioned purpose; The lateral deformation of the utility model restriction masonry panel to drawing the anchor pole device; Comprise the anchor rod body that passes preparatory restriction masonry panel, be located at the inboard pallet and the outside pallet of preparatory restriction masonry panel both sides respectively, the outside of outside pallet is provided with the nut that is fixed, and the outside of interior outside pallet is respectively equipped with the anti-attrition packing ring; The T-shaped pier nose in inboard termination of described anchor rod body, outboard end is for there being the rolled thread section; The length of said rolled thread section is 150 ~ 200mm.
Beneficial effect: the utility model make full use of two carry a tray clamping anchor structure; At utmost bring into play the tensile strength of anchor rod body; Through the adjustment nut screw and pine moves back the adjustment and the control that can realize the anchor pole working resistance; The initial stage of both can having realized in time screws and rises resistance, and pine moves back and suitably lets pressure in the time of can realizing after-deformation again; Because two ends all are the anchor structures of pallet clamping, and reliable origin of force can be provided, avoided because of adopting the anchoring agent to carry out anchoring; Cause the anchoring section bond damage to lose efficacy during the country rock large deformation; The tensile strength of anchor rod body is given full play in the generation of accidents such as the sliding anchor that causes, slip, significantly improves system supporting power; Strengthen supporting effect, be specially adapted to the anchoring of the masonry panel of large deformation; It is simple in structure, and good fixing effect has practicality widely.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: anchor rod body-1, inboard pallet-2, outside pallet-3, nut-4, anti-attrition packing ring-5, preformed hole-6 limits masonry panel-7 in advance.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Shown in the accompanying drawing, the restriction masonry panel lateral deformation of the utility model to drawing the anchor pole device, main warp is made up of anchor rod body 1, inboard pallet 2, outside pallet 3, nut 4, anti-attrition packing ring 5.Wherein: the T-shaped pier nose in inboard termination of anchor rod body 1; Outboard end is for there being the rolled thread section; The length of rolled thread section is 150 ~ 200mm, and anchor rod body 1 passes the preformed hole 6 of preparatory restriction masonry panel 7, and inboard pallet 2 and outside pallet 3 are located at the both sides of preparatory restriction masonry panel 7 respectively; The outside of outside pallet 3 is provided with the nut 4 that is fixed through the rolled thread section, and the outside of interior outside pallet is respectively equipped with anti-attrition packing ring 5.
During installation, at first anti-attrition packing ring 5 and inboard pallet 2 are passed anchor rod body 1 successively, and anti-attrition packing ring 5, inboard pallet 2 are pushed into T shape pier nose place; By goaf one side,, anchor rod body 1 is passed preparatory restriction masonry panel 7 through the preformed hole 6 on the preparatory restriction masonry panel 7; In the rolled thread section that exposes outside pallet 3, anti-attrition packing ring 5 and nut 4 are installed respectively; Use torque wrench fastening nut 3 then, reach required moment numerical value, form the anchor structure of two ends clamping.
Claims (2)
- One kind limit the masonry panel lateral deformation to drawing the anchor pole device; It is characterized in that: it comprises the anchor rod body (1) that passes preparatory restriction masonry panel (7), is located at the inboard pallet (2) and the outside pallet (3) of preparatory restriction masonry panel (7) both sides respectively; The outside of outside pallet (3) is provided with the nut (4) that is fixed; The outside of interior outside pallet is respectively equipped with anti-attrition packing ring (5); The T-shaped pier nose in inboard termination of described anchor rod body (1), outboard end is for there being the rolled thread section.
