Abstract
The utility model relates to a rapid mounting flexible anchoring-bolt, comprising steel wires(1) and a lockset. The lockset consists of a lock tube(21) and a lock core(22) wedged in a lock tube(21). The external surface of the lock tube(21) is sheathed with a nut(3) connected with the lock tube(21) through thread. As the lockset and the steel wires are preassembled together, shoring with the help of roof-bolter without using expanding strain device and special blender can be constructed directly, and the utility model is capable of simplifying the construction process and saving the steel wires.
Description
Technical field:
The utility model relates to the flexible roof bolt that a kind of mine construction supporting is used.
Background technology:
At present, mine breaking roof anchoring, loosening massif are fixed and the tunnel inwall is reinforced the flexible roof bolts that adopt more, and flexible roof bolt is made up of steel strand and lockset two parts, and lockset is made up of a lock tube and a lock core, during construction, at first punch being reinforced on the body, the anchoring agent is headed into the hole with steel strand at the bottom of, manually tighten special-purpose agitator at the exposed junction of steel strand, agitator links to each other with roof-bolter, behind steel strand rotation stirring anchoring agent some minutes, stop operating again, solidify some minutes.At this moment steel strand by the anchoring agent be frozen into one by anchoring body, manually pull down special-purpose agitator then, lock tube, the lock core of supporting plate, lockset are penetrated steel strand successively, draw jack to be connected with rising the exposed junction of steel strand, pressurize to rise then and draw, with lockset and supporting plate, locked, finish the whole erection process by the anchoring body fluid-tight engagement.Because this structure of existing anchor pole, make steel strand and lockset to be installed separately at the scene, so not only make the mounting process complexity, need the special-purpose agitator and the tension equipment that rises, and rise with the tension equipment that rises and to need when drawing manyly with 50cm left and right sides steel strand, cause waste of material.
Summary of the invention:
The purpose of this utility model is to provide a kind of fast-assembling flexible roof bolt that can simplify working procedure and save steel strand when supporting construction.
The utility model fast-assembling flexible roof bolt comprises steel strand and lockset two parts, and lockset is made up of the lock core of lock tube and wedging lock tube, is with the nut that is threaded with lock tube in the lock tube periphery.
Because the utility model flexible roof bolt is made up of steel strand and lockset, lockset is made up of lock tube and lock core, adding man-hour, can in advance lockset and steel strand installation locking be one, during construction supporting plate is penetrated steel strand, on lock tube, screw in hold-down nut, screw in one again and stir nut, directly block the stirring nut with roof-bolter, the rotation steel strand stir the anchoring agent, this moment, hold-down nut rotated synchronously with steel strand, after treating that the steel strand precession is solidified, remove the stirring nut, rotate hold-down nut again, the locking supporting plate is finished installation process.Because the lockset and the steel strand assembled in advance of the utility model flexible roof bolt are one, with the direct construction supporting of roof-bolter, simplified working procedure, saved rise tension equipment and special-purpose agitator, steel strand do not need to stay the surplus of 50cm more yet simultaneously, have saved steel strand.
Description of drawings:
Fig. 1 is the utility model structural representation.
The specific embodiment:
As shown in Figure 1, the utility model fast-assembling flexible roof bolt is made up of steel strand 1 and lockset two parts, lockset is made up of the taper lock core 22 of lock tube 21 and wedging lock tube 21, lock core 22 is for having the taper sheath of the mouth that tightly rises, before supporting construction, can in advance steel strand 1 be passed lock core 22, lock tube 21, utilize lock core 22 lockset to be locked at an end of steel strand 1, the steel strand 1 of a little are only exposed in the outer end of lock core 22, outer periphery screw thread at lock tube 21, and be with nut 3, because of this flexible roof bolt utilizes the double nut precession when the supporting construction, thus the length of lock tube 21 to suit, should be greater than the thickness of two nuts.
Claims (1)
1, a kind of fast-assembling flexible roof bolt comprises steel strand (1) and lockset two parts, and lockset is made up of the lock core (22) of lock tube (21) and wedging lock tube (21), it is characterized in that: be with the nut (3) that is threaded with lock tube (21) in lock tube (21) periphery.
