Abstract
The utility model relates to a fiber enhanced whole length anchor fixing bolt, which is composed of a rod body, a female screw and a tray, wherein screw thread is arranged on a surface through-body of the rod body, the screw thread and the rod body are an integral structure, the female screw is screwed on the rod body, the tray is close to the female screw and is sleeved on the rod body, and the rod body and a screw thread surface are also provided with an antistatic layer. The electrical resistance of the utility model is lower than or equal to 3*10<8> ohms, the flaming combustion maximum single value is smaller than or equal to 15 seconds, the flameless combustion maximum single value is smaller than or equal to 60 seconds, the screw thread on the rod body is obtained through once molding on the rod body, the tensile strength of the bolt is intensified, the bearing capacity can satisfy higher design requirements, both the connecting strength and the bearing strength of the female screw and the tray are bigger than or equal to 90 kilonewtons, and the rod body of the bolt is hollow and can realize hollow grout injection. The fiber enhanced whole length anchor fixing bolt provides forceful technical supports in the fields of system bolt support in tunnel engineering, support of coal mine tunnels, slop and dam engineering and the like.
Description
Technical field
The utility model relates to a kind of bolt support product that engineerings such as tunnel, frontier defense ramp, coal roadway support, water conservancy and hydropower, military people's air defense are used that is used for, and is specially a kind of fiber reinforcement full length fastening anchor pole.
Background technology
Bolt support is as the main flow of active support, in China's large-scale popularization and application now.Existing anchor pole form mainly is divided into anchor metal and glass fiber anchor pole, and anchor metal exists perishable, and application life is short, and shortcomings such as difficulty are installed in transportation.Though and existing glass fiber anchor pole is corrosion-resistant, still has many defectives, making it can't large-scale promotion: 1, body of rod screw thread load is low, and itself and nut bonding strength are below 90,000 newton; 2, its body of rod does not possess antistatic property, and the not high defective of fire resistance is obvious; 3, it mostly is end anchorage greatly, non-full length fastening; 4, the glass fiber anchor pole mostly is the solid body of rod, is difficult to realize hollow grouting.The anchor pole of said structure, form, performance all is difficult to satisfy the higher technical requirements of applying unit.
Summary of the invention
The technical problems to be solved in the utility model is: existing glass fiber spiral thread on anchor bolt load is low, and the body of rod can not be antistatic, and non-full length fastening is difficult to realize hollow grouting.
The technical solution of the utility model is: a kind of fiber reinforcement full length fastening anchor pole, by the body of rod, nut, pallet constitutes, body of rod surface entire body is provided with screw thread, and the screw thread and the body of rod are integrated, and nut is spun on the body of rod, on the body of rod, the body of rod and thread surface also are provided with antistatic layer to pallet near nut sleeve.
The utility model body of rod can be hollow structure or solid construction, and the hollow size can be decided according to the requirement of actual design.Cooperate the grouting operation, lever front end also is provided with stop grouting plug, slurry is formed reflux, and evenly is filled in the gap of environment such as anchor pole and rock on every side, strengthens anchor rod anchored intensity, reaches better supporting effect.
Antistatic layer of the present utility model is by realizing resistance value≤3 * 10 at body of rod surface-coated liquid antistatic
8Ohm, the maximum monodrome of flaming combustion≤15 seconds, the maximum monodrome of flameless combustion≤60 seconds; The tensile strength of anchor pole has been strengthened in the directly once moulding and getting on the body of rod of screw thread on the body of rod, and bearing capacity satisfies higher designing requirement, and nut and pallet are glass fiber and make, its bonding strength and bearing strength all 〉=90,000 Ns; Anchor pole can be realized hollow grouting.In the system anchor bolt supporting of construction of tunnel, the supporting of coal mine roadway provides strong technical guarantee in the use in fields such as side slope and dam construction.
Description of drawings
Fig. 1 is that the utility model body of rod is the schematic diagram of solid construction.
Fig. 2 is that the utility model body of rod is the schematic diagram of hollow structure.
The specific embodiment
As shown in Figure 1, the utility model body of rod 1 and thread surface 4 thereof get for one-shot forming, the body of rod 1 and screw thread 4 surface applied liquid antistatics, HDC-305 type antistatic additive as the production of Dechang, Linan, Hangzhou chemistry Co., Ltd, form antistatic layer 5, the body of rod 1 adds fire retardants such as antimony oxide before shaping, make the anchor pole main body have antistatic property and fire resistance, and nut 2 and pallet 3 form for glass fiber and process of resin.
Fig. 2 is the schematic diagram of anchor rod body hollow, grouting machine slip casting in hollow hole in construction, the body of rod 1 front end is provided with stop grouting plug 6, uniform hole is arranged above, slurry form to be refluxed, evenly be filled in the gap of environment such as anchor pole and rock on every side, anchor pole and surrounding environment better are anchored at together, form an integral body, supporting effect is more obvious.
The utility model fiber reinforcement full length fastening anchor rod body fiber can be a glass fiber, also can be Black Warrior fiber, also can be carbon fiber.
